JP 2010-238214 A JP-A-2009-32143

In general, an image captured by a camera such as a drive recorder is constantly overwritten in a storage device. The drive recorder described in Patent Document 2 transmits image data when an event occurs to an external device, but image data when no event occurs is overwritten and deleted over time.

By recording image data and the like on a removable medium and passing the image data and the like to an external device before the image data and the like are overwritten, the image data and the like can be accumulated in the external device. However, with this method, the removable medium must be periodically removed from the drive recorder or the like and carried to an external device before the image data or the like is overwritten. SUMMARY OF THE INVENTION It is an object of the present invention to provide a system or the like that can reduce the trouble of carrying removable media and can effectively use various data other than when an event occurs.

The purpose of the invention of the present application is not limited to this, and we intend to acquire rights by divisional application or amendment, etc. for the structure aiming to obtain the effect produced by the parts of the structure disclosed in the specification, drawings, etc. . For example, the present specification discloses a problem in which the phrase "can be done" is read as "is the problem." The problems are described as being independent of each other, and we have the intention to independently acquire the rights to the structure for solving the problems through a divisional application or an amendment, etc. Even if the problem is implicitly grasped from the description of the specification, the applicant intends to claim part of the structure described in this specification in an amended or divisional application. Also disclosed is a combination of these independent tasks.

(1) Receiving vehicle-mounted device identification information, image data acquired by the vehicle-mounted device, and driving data representing the running state of the vehicle from the vehicle-mounted device via a wireless transmission path, and identifying the vehicle-mounted device. The system may have a function of creating a database by associating the information, the image data, and the travel data, searching the database based on search conditions specified by the user, and displaying the search results.

When transferring image data and driving data from in-vehicle equipment to this system, it is possible to reduce the trouble of carrying removable media and to effectively use various data other than when an event occurs. By displaying the results of searching the database based on the search conditions, the user can easily find the necessary data from the database containing a huge amount of data. Here, the user includes a vehicle driver, an operation manager who manages the operation of the vehicle, and a system administrator who manages this system. Note that the operation manager may also serve as the system manager.

Vehicles equipped with in-vehicle devices include passenger cars, trucks, buses, and other vehicles that run on general roads, special vehicles such as forklifts that run on specific premises, streetcars that run on tracks, and trains that run on railways. included. It is preferable to collect data from a plurality of in-vehicle devices. This allows us to collect more information. As the in-vehicle device, for example, a drive recorder or the like having a built-in imaging device and a storage device may be used. As the wireless transmission line, a mobile communication network provided by a telecommunications carrier (for example, a transmission line of the LTE standard), a wireless LAN installed by the user of this system, or the like may be used. For example, a wireless transmission path (for example, a WiFi standard transmission path) is formed between an access point of a mobile communication network or a wireless LAN and an in-vehicle device. A wired or wireless transmission line may be used as the transmission line between the access point and this system.

It is preferable to determine whether to use a mobile communication network or a wireless LAN as a wireless transmission path according to the moving range of the vehicle whose data is to be collected. For example, when collecting data from in-vehicle equipment mounted in a vehicle such as a forklift that moves within a specific premises, a wireless LAN may be used. The number of wireless LAN access points should be determined according to the size of the area to be covered by the wireless transmission line and the hierarchical structure. A mobile communication network may be used to collect data from vehicles that travel over a wide area that cannot be covered by a wireless LAN, such as long-distance trucks and taxis. It is preferable that data can be transmitted from the in-vehicle device to the present system using both the mobile communication network and the wireless LAN. In this case, when the vehicle is located within the communicable range of the wireless LAN, communication is preferably performed via the wireless LAN, and otherwise, communication is performed via the mobile communication network.

In-vehicle equipment installed in a vehicle that may run outside the wireless LAN coverage area determines whether the current location is within the wireless LAN coverage area based on current location information acquired by GPS, etc. and search for an access point if it is within a communicable area. If GPS radio waves cannot be received and the current position information cannot be obtained (when positioning is not performed), it is preferable to periodically search for an access point at regular intervals.

It is preferable that in-vehicle devices mounted on vehicles that basically work within a premises where wireless LAN communication is possible search for access points all the time. When the access point cannot be detected, it is preferable to repeatedly execute (retry) the process of searching for the access point. The system should preferably have a function for setting the number of retries or the retry cycle in correspondence with the non-detection time. For example, the longer the non-detection time, the longer the retry period. For example, when the non-detection time is 10 minutes or less, the retry period may be set to 5 seconds, and when the non-detection time is 10 minutes to 1 hour, the retry period may be set to 2 minutes. It is further preferable that the system has a function of notifying the operation manager when the non-detection time exceeds a predetermined upper limit value, for example, one hour. The correspondence relationship between the non-detection time and the retry period may be changed according to the installation status of the access point or the like.

When a mobile communication network is used as a wireless transmission path, the vehicle-mounted device should always search for an access point. When the access point cannot be detected, it is preferable to repeatedly execute (retry) the process of searching for the access point. As in the case of using a wireless LAN, it is preferable that this system has a function of setting the number of retries or the retry cycle in correspondence with the non-detection time.

The vehicle-mounted device identification information is information for specifying one vehicle-mounted device among a plurality of vehicle-mounted devices. When one on-vehicle device is fixedly mounted on one vehicle and cannot be remounted between a plurality of vehicles, the vehicle can be identified by the on-vehicle device identification information. Furthermore, when the correspondence between the vehicle and the driver is fixed, the driver can be identified by the in-vehicle equipment identification information. When the in-vehicle device is remounted and used in a plurality of vehicles, vehicle identification information for identifying the vehicle should be added to the information transmitted to the system. Furthermore, if there is a possibility that one vehicle will be driven by a plurality of drivers, it is preferable to add driver identification information for identifying the drivers to the information transmitted to the system. When a removable medium is attached to an in-vehicle device and operated, media identification information for identifying the removable medium should be added to the information to be transmitted to the system. When the driver carries and uses a specific removable medium, the removable medium identification information can be used as information for identifying the driver.

Image data acquired by the in-vehicle device may include, for example, image data in front of the vehicle. It is even better to include at least one of rear, side, and interior image data. More information can be gathered by including image data such as the rear of the vehicle. This image data may be moving image data, for example. By collecting moving image data, it is possible to obtain information about motion that cannot be obtained from still images. Data may be transmitted from the in-vehicle device to the system all the time, not only when a specific event such as an accident occurs in the vehicle, but during the period when communication via the wireless transmission line is possible. As a result, various kinds of information other than when an event occurs can be stored in a database.

The travel data may include, for example, date and time information, position information, speed information, acceleration information, event occurrence factor information, driver's operation information, and the like. The date and time information represents the date and time when the image data was captured. Latitude and longitude information acquired by a global positioning system (GPS) receiver, for example, may be used as the position information. For example, the vehicle-mounted device may acquire the speed information from the vehicle via a vehicle-mounted network such as CAN. Acceleration information may be acquired from a three-axis acceleration sensor that measures front-rear, vertical, and horizontal accelerations mounted on the vehicle-mounted device.

As search conditions instructed by the user, for example, information regarding date and time or period, information regarding position, vehicle identification information, driver identification information, event occurrence factors, etc. may be employed. The positional information may be, for example, latitude and longitude, name of a specific intersection, distance from the intersection, address, information indicating a specific division when a certain area is divided into a plurality of divisions, and the like. To allow the user to specify a specific point such as latitude and longitude, display a map on the screen and allow the user to specify a specific point on the displayed map with a pointing device (e.g., mouse, touch panel, etc.). . For the display of search results, for example, a map format, a list format, or the like may be adopted.

Examples of event occurrence factors include acceleration (magnitude of impact applied to the vehicle) exceeding a threshold value, vehicle running speed exceeding the legal speed limit, and occupants performing an event recording operation on in-vehicle equipment. factors such as driving conditions. The information indicating the legal speed limit may be obtained, for example, by analyzing the image in front of the vehicle and obtaining the speed limit road sign. In addition, the legal speed information may be added to the map information of the car navigation device, and the legal speed information included in the map information and the current position information of the vehicle may be used to obtain the legal speed information.

This system may be implemented by a computer, such as a personal computer, installed at the user's place of business. This system may be realized by installing database software and an application program using the database in this computer. The application program may be implemented by adding a function to access the database and a function to specify search conditions to a conventional personal computer viewer for viewing image data and driving data recorded by a drive recorder, for example. . It is even better if the application program has a function of searching for necessary data with additional search conditions from the data extracted from the database.

The system may consist of a database server and a client. At this time, the database server and the client should be connected by a wired LAN or a wireless LAN. Terminals that are not connected to this LAN should be prevented from accessing the database server. As a result, it is possible to prevent the data stored in the database from leaking out of the office.

In (1) above and (2) to (26) described below, a system that collects image data and driving data from in-vehicle equipment installed in a vehicle is described as an example. A system that collects image data captured by a camera may also be used. As a fixed point camera, for example, a surveillance camera installed to check the normality of the operation status of equipment in a factory, a surveillance camera installed in the premises where work vehicles move, and installed on the road where an unspecified number of people pass. security cameras installed in the building, and security cameras installed in the entrances and hallways of buildings. Data acquired by such a fixed-point camera does not include data corresponding to traveling data. For example, image data and date/time information may be transmitted from these cameras to a database system. Further, instead of the in-vehicle device identification information, the device identification information for identifying the camera may be transmitted from the fixed point camera to the database system. When this system collects data from a fixed point camera, it is preferable to use a wireless LAN as a wireless transmission line. If the wireless LAN access point cannot be detected, it is considered that some abnormality has occurred in the wireless LAN system. Alternatively, data may be transferred to the present system via a wired transmission path without via a wireless transmission path. The applicant of this application also intends to obtain a patent for a system that receives data from these fixed point cameras and creates a database.

In this system, when wireless communication is possible, image data and driving data are always sent from the in-vehicle device to the system. Alternatively, the vehicle-mounted device may transmit image data and travel data requested by the received command to this system. For example, the system transmits a command "send the image data acquired during the month, day, hour, minute, and minute". The in-vehicle device should read the image data corresponding to the content of the request from the removable medium and send it to the system. In general, it is difficult to simultaneously read and write to removable media such as SD cards. Therefore, when reading image data, writing should be temporarily stopped. If the amount of data to be read is small, writing and reading may be executed simultaneously. If the amount of data to be read is less than a predetermined amount, it is preferable to read the necessary data without interrupting writing.

(2) The system may further include a function of performing image analysis on the image data after receiving the image data from the vehicle-mounted device, and storing the analysis result in the database in association with the image data.

When the image analysis results are stored in the database, the image analysis results can be used as search keys without performing image analysis when searching the database. As a result, search speed can be increased.

For example, image analysis can determine whether an accident has occurred around the vehicle, whether an accident did not occur, but whether a situation corresponding to a near-miss incident has occurred, whether a traffic light is reflected in the image, etc. Whether or not a pedestrian is reflected in the image, whether or not a predetermined road sign is reflected in the image, whether or not a vehicle is reflected in the image, and if a vehicle is reflected, the vehicle Appearance features, etc., may be determined. The analysis results may be converted into text data, coded, or flagged, and stored in a database, for example. Information such as vehicle color, vehicle classification, license plate, etc., may be employed as the external features of surrounding vehicles. Vehicle categories may include, for example, buses, trucks, passenger cars, motorcycles, and the like. For example, if it is desired to know the running state of a red passenger car at a certain place during a certain time period, the analysis results regarding the vehicle color and vehicle classification can be used. Further, by using the analysis results regarding the presence or absence of an accident, it is possible to easily search whether or not images of accidents that occurred at a certain place on a certain date and time are stored in the database. If an image of the accident is stored in the database, this image will provide useful information for identifying the cause of the accident.

In addition, it is preferable to analyze the image inside the vehicle, identify the driver by face authentication, and store the driver identification information in a database. For example, after the driver's seat becomes vacant, face authentication of the driver may be performed each time it is detected that the driver has taken the driver's seat.

In the system described in (2) above, after image data is received, image analysis is performed before it is stored in a database. It is preferable that the present system has a function of analyzing the image being reproduced and determining whether or not a near-miss incident has occurred during the period in which the image is being reproduced. It is preferable that the present system has a function of stopping the reproduction at the moment when the occurrence of a near-miss incident is detected and notifying the viewer of the image of the occurrence of the near-miss incident.

As another configuration, for example, a system that analyzes image data from a monitoring camera installed to confirm the normality of the operating conditions of devices in a factory may be used. If the device has a function to notify the occurrence of an abnormality by a method such as blinking an alarm lamp when an abnormality occurs, it is preferable to detect the blinking of the alarm lamp by image analysis and determine whether or not there was a notification of the occurrence of an abnormality. It is preferable to store information on the presence or absence of an abnormality in the database as an analysis result.

(3) the travel data includes current position information of an in-vehicle device, and after receiving the travel data from the in-vehicle device, assigns the current position of the vehicle to one of a plurality of groups based on the current position information; The system may further include a function of classifying, associating the travel data with information on the group to which the current position belongs, and storing the information in the database.

By searching the database using the group as a search key, it is possible to perform a rough search based on the position of the vehicle in a short period of time, compared to searching by the latitude and longitude of the position of the vehicle.

As the plurality of groups for classifying the current position, for example, the map may be divided into a plurality of sections by dividing it with a mesh, and the plurality of divided sections may be adopted. The size of the partition may be, for example, a square with a side length of 50 m to 100 m. In this case, it is preferable that the points existing in the band-shaped area of a constant width including the boundary line of the division belong to the two divisions on both sides of the boundary line. As a result, even when the search target point is located very close to the boundary line, it is possible to avoid missing necessary data in the search.

Alternatively, the current location may be grouped based on distance from each of a plurality of intersections. For example, it is preferable to classify into a group with a distance of 100 m or less from the intersection A, a group with a distance of 100 m or less from the intersection B, or the like. By grouping in this way, it is possible to easily extract image data and travel data acquired near the intersection using the name of the intersection as a search key.

In addition, as a plurality of groups for classifying the current position, it is preferable to adopt the address of the current position, for example, the name of the municipality (up to the town name of the residential address). By grouping in this way, it is possible to easily extract image data and travel data acquired within the address using the address as a search key.

(4) A map and an input area for inputting search conditions are displayed on the screen, and when the user inputs search conditions in the input area displayed on the screen, data (records) satisfying the input search conditions are displayed. The system may further include a function of displaying a mark at a position on the map specified by the current position information included in the data (record) extracted from the database.

The user can easily grasp the position on the map where the data satisfying the search condition was obtained. For example, by specifying the start date and time, the end date and time, and the event occurrence factor as search conditions, the points where the event occurred due to the specified event occurrence factor between the specified start date and time and the end date and time will be displayed on the map. can be displayed. A mark such as a flag pattern or a balloon pattern may be used as the mark to be displayed on the map.

It is preferable to display a pane for displaying a map and a pane for inputting search conditions in one window. It is good to display the item name of the search condition and the check box in the pane for entering the search condition. Detailed conditions are preferably selected from a pull-down menu, pop-up menu, or the like. Narrowing down the search conditions reduces the number of marks displayed on the map, and loosening the search conditions increases the number of marks displayed on the map. The user can set appropriate search conditions while confirming the increase or decrease of marks.

(5) A function that displays a map on the screen and allows the user to designate a part of the area from the displayed map; The system may further include a function of extracting from the database and displaying a mark at a position on the map corresponding to the extracted data (record).

The user can intuitively specify a position by specifying a partial area from the map displayed on the screen. Dragging with a mouse, pinch-in, pinch-off on a touch panel, or the like may be adopted as an operation for specifying a partial area from the map. Furthermore, as shown in (4) above, it is preferable to allow the user to input search conditions other than position information, such as date and time information, event occurrence factors, and the like. Necessary information can be easily found by gradually narrowing down the area on the map and other search conditions. For example, it is possible to gradually narrow down the search conditions based on memories of the month, day, and time when the brake was suddenly applied.

When this system consists of a database server and a client, the database is first searched using rough conditions and the extracted data is transferred to the client. It is preferable to provide a function for searching data. As a result, the number of accesses to the database can be reduced.

(6) A function that allows the user to enter an address as a search condition, and searches the database using both the old address display and the current address display as keys when there is a history of changes in the address display of the input address. , the system may further include:

At the time of travel data collection, a database is created based on the address display at that time. After that, even if the address display is changed due to merger of municipalities, introduction of residential display, etc., necessary data can be extracted based on the changed address display. Conversely, even if the search condition is set based on the old address display, it is possible to extract data having the corresponding address display after the change. In addition to the address display, this system has a function to search for data associated with the intersection even if the name of the intersection is changed, using either the old intersection name or the new intersection name as a search key. Good.

(7) The system may further include a function of reading the image data and the travel data recorded on a removable medium installed in on-vehicle equipment installed in the vehicle and storing the data in the database.

It is possible to store data recorded on removable media during a period in which wireless communication was not possible, data recorded on removable media by in-vehicle devices that do not have wireless communication functions, etc., in the database. By storing the data of the period during which the wireless transmission line communication was not possible in the database, the image data and the travel data can be stored in a database without a break in time. By importing data from in-vehicle devices that do not have wireless communication functions, the database can be further enhanced. A removable media reader may be included in the system to read data recorded on removable media.

When data is transmitted to this system via a wireless transmission line after the operation of the vehicle is completed, it is desirable to keep the engine of the vehicle running until the data transmission is completed. When data is read into the system via removable media, the engine may be stopped after the vehicle has finished running. By using data transfer via removable media, data loss is less likely to occur in the image data and driving data for each driver. It becomes difficult for unfairness to occur in each evaluation. For example, it is possible to incorporate image data and driving data during the period when the vehicle is driving in a remote area or in the mountains where the radio wave of the mobile communication network does not reach, in the evaluation of the driver.

As one attribute of the database, it is preferable to include data acquisition method identification information for identifying the method by which the data was acquired. Data acquisition method identification information may be used to identify any one of wireless LAN, mobile communication network, and removable media. The user can search the database using the data acquisition method identification information as a search key.

The image data and travel data on the removable media may include a transmitted flag for identifying whether or not they have been transmitted via the wireless transmission path. When reading image data and driving data from removable media into this system, the image data and driving data for which the transmitted flag is not set will be read, and the image data and driving data for which the transmitted flag is set will be transferred to the system. The system should have a function not to read. If the sent flag is not recorded on the removable media, when data is read from the removable media, it will be recorded on the removable media based on the removable media identification information, in-vehicle equipment identification information, image acquisition time, image frame counter, etc. It is preferable that the system has a function of determining whether or not the image data stored in the database has already been stored in the database, and reading the image data, etc., that are not stored in the database.

(8) A function to transmit at least one of a command to change the setting information that determines the operating conditions of the on-board device and a command to update the firmware of the on-board device to the on-board device via a wireless transmission path. , the system may further include:

The operation manager can change the setting information of the in-vehicle device without going to the vehicle in which the in-vehicle device is mounted. In addition, the system administrator can update the firmware of the vehicle-mounted device without going to the vehicle in which the vehicle-mounted device is mounted.

If the operation manager or system administrator performs an operation to change the setting information or update the firmware without specifying a specific onboard device, this system will change the setting information or It is advisable to update the firmware. It is possible to simplify the change or update operation compared to the case where setting information change or firmware update operation is performed for each of a plurality of managed in-vehicle devices.

Further, the system preferably has a function of classifying a plurality of on-vehicle devices to be managed into a plurality of groups, and changing setting information or updating firmware for each group. For example, the on-vehicle devices may be classified according to the safe driving level and skill level of the driver of the vehicle in which the on-vehicle devices are mounted. For example, it is preferable to classify drivers into three groups of high, normal, and low safe driving levels, and classify in-vehicle devices into three groups according to the correspondence between drivers and in-vehicle devices. For example, in a vehicle driven by a driver with a high degree of safe driving, it is difficult for the event triggered by the acceleration to occur because it is difficult for a situation in which acceleration such as sudden start or sudden braking occurs to occur. In order to detect an event to some extent even in a vehicle driven by a driver with a high degree of safe driving, it is preferable to set the acceleration threshold for determining that an event has occurred to be lower than the thresholds for other groups. Conversely, for vehicles of drivers with a low degree of safe driving, the resolution of image data to be recorded should be higher than that of other groups to facilitate cause analysis when accidents or near-miss incidents occur. In addition, it is preferable to classify drivers who have a strong tendency to perform dangerous actions or actions while driving into a specific group, and set the in-vehicle device corresponding to the driver to collect detailed images of the interior of the vehicle. . Here, examples of "detailedly" include increasing the resolution, increasing the frame rate, and the like.

In addition, it is preferable to group the in-vehicle devices according to the department in the company to which the driver belongs. For example, it is preferable to group by department such as a design department, a sales department, and a planning department.

When the operation manager or system administrator operates this system and instructs to change the setting information of the on-board equipment or update the firmware, the setting information will be changed for the on-board equipment that cannot communicate wirelessly. The system should have a function of reserving changes or reserving firmware updates. When the in-vehicle device for which a reservation for setting information change or firmware update has been reserved becomes capable of wireless communication with this system, the system may send a command for changing the setting information or updating the firmware to the on-vehicle device.

The system should have a function to send a command to format (initialize) the removable media of the on-board device from the system to the on-board device. For example, when it becomes necessary to reformat the removable medium due to updating the firmware of the vehicle-mounted device, it is preferable to format the removable medium of the vehicle-mounted device using this function.

It is preferable that the system administrator operates this system, for example, a personal computer, to send commands such as updating the firmware and formatting the removable media. In the case of firmware update that requires formatting of removable media, when the system administrator operates the firmware update, formatting of the removable media is required and the image data and driving data recorded up to now It is a good idea to notify the system administrator that the At this time, it is more preferable to notify the system administrator whether or not image data and travel data that have not been transmitted to the present system remain in the in-vehicle device. After this notification, it is preferable to allow the system administrator to select whether to update the firmware or cancel it. As a result, it is possible to prevent the occurrence of a situation in which image data and travel data are erased even though the system administrator wants to keep them.

The system may have a function of instructing the in-vehicle device to format the removable media after sending all image data and travel data recorded on the removable media to the system. When receiving this command, the vehicle-mounted device should have a function to automatically start formatting the removable media after sending all the image data and driving data recorded on the removable media to this system.

When the system administrator performs an operation to update the firmware, the system notifies the system administrator that the recording of the onboard device will be interrupted during the firmware update before sending the command to update the firmware to the onboard device. should be notified to After sending this notification, the system should allow the system administrator to select whether to execute or cancel the firmware update. This allows system administrators to cancel the firmware update if they do not want to interrupt the recording.

(9) The database includes driver identification information that identifies a driver of the vehicle, and further includes a function of setting data management conditions of the database for each driver identified by the driver identification information. system.

Data can be managed by setting optimal data management conditions for each driver. Data management conditions may include, for example, the upper limit of storage capacity, data storage period, attributes of image data, necessity of event recording, and the like.

Since the storage capacity of the database is finite, when the amount of data accumulated in the database reaches the upper limit of the storage capacity, the past data must be deleted or discarded without storing new data. If the maximum capacity of the storage area corresponding to a specific driver is increased and the data retention period is set long, data relating to that driver will be less likely to be erased. For example, by making the maximum capacity of the storage area for the data about the driver to be managed intensively larger than the maximum capacity of the storage area for the data about the other drivers, the data about the driver to be managed intensively is less likely to be deleted. You can get the effect of becoming

By making the retention period of the data on the driver to be managed intensively longer than the retention period of the data on the other drivers, the data on the driver to be managed intensively can be stored for a longer period of time. For example, the driver may set the data storage period to one day or one year.

For example, the resolution, frame rate, etc. may be used as attributes of the image data. When the operation manager operates this system to specify the driver and input the attributes of the image data, this system acquires the identification information of the in-vehicle equipment installed in the vehicle in which the specified driver rides, and It is preferable to transmit a command to change to the input attribute to the vehicle-mounted device corresponding to the vehicle-mounted device identification information. The in-vehicle device that receives this command should change the attribute of the image data to be recorded and transmitted.

When the operation manager operates this system to designate a driver and set whether or not to record an event, the system acquires the identification information of the on-vehicle equipment installed in the vehicle in which the designated driver rides, and It is preferable to transmit a command to change the set value of whether or not to record the event to the on-vehicle device corresponding to the on-vehicle device identification information. Upon receiving this command, the vehicle-mounted device may enable or disable the event recording function according to the set value of whether or not event recording is necessary.

Instead of setting these settings on a driver-by-driver basis, multiple drivers may be grouped into multiple groups so that these settings can be changed for each group. For example, drivers may be classified into groups such as "excellent", "normal", and "dangerous" according to their driving skills and driving attitudes. In this way, the data management condition setting operation by the operation manager can be simplified compared to the case where the data management conditions are set by designating each driver.

This system should have a function of outputting the labor management information for each driver in the form of a list based on this database. In addition, it is preferable to have the operation manager input the driver for whom the labor management information is to be output, the work period, and the like. Furthermore, it is preferable to have a function of outputting the labor management information for each office in the form of a list.

It is preferable that this system has a function of collecting image data of security cameras installed in convenience stores, ATMs, condominiums, shopping streets, etc., and that the data storage period can be set for each security camera.

(10) A function to display the contents of a plurality of attributes of the database on one screen, to instruct the user whether or not to print for each attribute, and to print the contents of the attribute required to be printed by the user's instruction to the printer. It is preferable that the system further includes a printing function.

A user such as a driver or an operation manager can easily grasp the contents of a plurality of attributes on one screen. Also, the user can determine whether or not printing is necessary while looking at the content displayed on the screen, and can easily instruct the attributes to be printed.

For example, the system may divide one window into a plurality of areas (panes) and display the contents of the attributes of the database in each pane. Further, a print necessity box is displayed in the corner of each pane, and the user checks the print necessity box to instruct printing of the contents of the attribute displayed in the pane. good. Further, by setting the brightness of the pane selected by the user higher than the brightness of the other panes, it is possible to distinguish whether or not the pane is the pane for which the user has instructed printing.

The system may have a function of automatically correcting the size and layout of the pane to be printed according to the pane to be printed. It is even better if the user has a function to register the print layout in advance. Once the user selects which panes to print and the print layout, the system prints the contents of the selected panes in the selected print layout. For example, the user can register in advance an image-oriented layout in which an image obtained by an in-vehicle device is printed in a large size, a map-oriented layout in which a map is printed in a large size, and the like.

The system may further have a function of registering a print layout for each group or each driver when drivers are classified into groups. When the user designates a pane to be printed and instructs printing, the system preferably performs printing in a print layout registered in advance for a group of drivers to be printed or a driver.

On one screen, for example, an image acquired by an in-vehicle device, a map of a certain range including the vehicle position, a mark indicating the vehicle position, a graph showing the measured values of speed and acceleration, and a database search condition. It is preferable to display a list of search condition items, an operation panel for performing operations such as playback, stop, fast-forward of images, and the like.

When the user selects one item from the search condition item list, the display content of the pane displaying the search condition item list may be switched to a display for inputting detailed conditions related to the selected item. For example, when the user selects the item "driver" from the search condition item list, a list of driver names may be displayed in the pane to prompt the user to select a driver name. Also, when the user selects "date and time" from the search condition item list, the pane may be switched to display content for inputting the date and time period.

When the user inputs search conditions by operating panes for inputting search conditions, it is preferable to switch the display contents of other panes to information that satisfies the search conditions entered by the user. For example, when the user selects a specific driver, an image acquired by the in-vehicle equipment of the vehicle in which the driver is riding may be displayed in the image display pane.

(11) The database includes date and time information and location information when the image was acquired, and based on at least one of the date and time information and the location information, the content of the image data and the travel data acquired from a plurality of in-vehicle devices is displayed on the screen. It is preferable that the system further includes a function to simultaneously display the

Images acquired at the same time by a plurality of in-vehicle devices or images acquired by a plurality of in-vehicle devices having a specific positional relationship can be browsed while being compared on the screen. For example, by browsing the image of the on-vehicle equipment installed in a vehicle that was traveling in a specific place during a certain time period, it is possible to obtain more information about an accident or the like that occurred in that specific place. For example, when moving with multiple trucks, by viewing the images of the in-vehicle equipment installed in each truck at the same time, information about an accident that occurred in one truck can be displayed in other trucks. can be obtained from the image. In-vehicle devices are installed in the first and last cars of a train, and images obtained by the on-board devices in the first and last cars are viewed simultaneously. be able to. In addition to the date/time information or position information, it is further preferable to have a function of simultaneously displaying the contents of the image data and the travel data on the screen based on a plurality of vehicle-mounted device identification information specified by the user.

(12) Further receive radio wave intensity information indicating the radio wave intensity of the wireless transmission path from the in-vehicle device, associate the current location information of the in-vehicle device with the radio wave intensity information, and store the radio wave intensity information in the database to visualize the distribution of the radio wave intensity. It is preferable that the system further includes a function of displaying on the screen as an image.

Areas with weak signal strength can be easily identified. This information can be used as effective information when increasing the number of access points. If LTE is used as the radio transmission path, this information should be provided to the mobile communication operator. If the company is constructing a wireless LAN, it is advisable to provide this information to the wireless LAN management department and encourage them to increase the number of access points.

When the radio field strength is 0 or too weak to transmit data by wireless communication, the in-vehicle device stores the radio field strength and the location information in association with each other. It is advisable to send it to this system. As a result, the system can obtain information about the radio wave intensity in areas where communication is impossible.

For example, the system may have a function of displaying the distribution of radio wave intensity by displaying a map color-coded according to the radio wave intensity. It is even better if a function for displaying an icon or the like is provided at the location of the access point on the map.

(13) Receive the value of the overwrite counter from the in-vehicle device having the overwrite counter that overwrites the image data on the removable medium and records the number of overwrites via the wireless transmission line, and the value of the overwrite counter is the recommended overwrite. The system may further include a function of judging whether or not the upper limit has been exceeded, and prompting the user to replace the removable medium if the value of the overwrite counter exceeds the recommended upper limit of overwriting.

If the number of overwrites on removable media exceeds the recommended overwrite limit, write errors are more likely to occur. A user, such as an operation manager or a system administrator, who is prompted by the present system to replace the removable medium replaces the removable medium, thereby suppressing the occurrence of write errors. The upper limit of the recommended number of overwrites is determined by the specifications of the removable media.

The in-vehicle device or this system should have a function to format removable media. When formatting removable media, the value of the overwrite counter should be inherited after formatting. For example, it is preferable to read and store the value of the overwrite counter before formatting, and write the value before formatting to the overwrite counter after formatting.

(14) Calculate the length of the period during which data is not received for each in-vehicle device, and determine whether the length of the period during which data is not received exceeds a predetermined non-communication time upper limit value. However, the system may further include a function of notifying the user when the length of the period during which no data is received exceeds a predetermined non-communication time upper limit value.

In principle, this system receives image data and driving data from the on-board equipment while the on-board equipment is operating normally and the vehicle is located within the communication area. For example, communication should be performed once a day with an in-vehicle device installed in a vehicle that is used to return to the parking lot of the office where the access point is installed once a day. In addition, in the case of long-distance trucks, which are used in vehicles that do not return for several days after leaving the parking lot of an office, the on-vehicle equipment returns to the parking lot once in a certain number of days. communication. If the number of days without communication exceeds the upper limit of non-communication time, it may be caused by a failure of the on-board equipment, an abnormality in the communication environment, or the driver turning off the power switch of the on-board equipment. An abnormal situation may occur. When the length of the period during which data is not received exceeds the predetermined non-communication time upper limit value, the user will notice the occurrence of such an abnormal situation by having the function of notifying the user. be able to.

The non-communication time upper limit value may be set according to the usage pattern of the vehicle. It is even better if the non-communication time upper limit value can be set for each driver or each group of drivers. Further, it would be even better if the non-communication time upper limit value could be set depending on whether a wireless LAN is used or a wireless network of a mobile communication carrier such as LTE is used as a wireless transmission path for communication. . For example, when using a wireless network of a mobile communication carrier, the non-communication time upper limit value may be shortened. For example, when there is no communication for one hour or more even though the vehicle should be traveling within the communication coverage area of the wireless network, the driver may turn off the engine of the vehicle and take a rest. It is considered that some unexpected situation has occurred, such as whether some kind of accident has occurred.

(15) Receiving an event occurrence signal notifying that an event has occurred from an in-vehicle device having a function to detect the occurrence of an event, and upon receiving the event occurrence signal, specifying the in-vehicle device in which the event has occurred and notifying the user. The system may further include a function to

A user such as an operation manager can quickly know that an event such as an accident, dangerous driving, or the like has occurred in a vehicle to be managed. The vehicle-mounted device may determine that an event has occurred, for example, when the value of acceleration detected by an acceleration sensor mounted on the vehicle-mounted device exceeds a predetermined threshold value. This system may, for example, push notification of the occurrence of an event to an application program on the PC of this system. The system should send an e-mail to the mobile terminal of the user or notify the user using a web service such as SNS.

(16) A function that allows the user to input matters to be communicated to the driver, and a command to output the matters to the in-vehicle equipment of the vehicle driven by the driver of the contact when the matters to be communicated to the driver are input. It is preferable that the system further includes a transmission function.

A user such as an operation manager can operate this system to inform the driver of the message. The in-vehicle device should preferably output the message in the form of voice, text, image, or the like.

In addition to inputting message items, it would be even better to have a function for allowing the user to input conditions for outputting message items to the in-vehicle device. As this condition, it is preferable to apply a condition relating to the position of the vehicle, for example, a condition that the current position of the vehicle is within a predetermined range. For example, if a condition is set that the current position of the vehicle is in the parking lot of the office, it is possible to notify the driver of the message when the vehicle returns to the parking lot of the office. For example, it is possible to cause the driver to output a message such as "There will be a barbecue party from 18:00 today. If you wish, please join us." can be done.

It would be even better to have a function of setting a time condition for outputting the message as a condition for outputting the message. For example, when the current time satisfies a set time condition, the system may send a command to the in-vehicle device to output a message. Alternatively, the system transmits the time condition to the in-vehicle device, and the on-vehicle device judges whether or not the set time condition is satisfied, and outputs the message when the time condition is satisfied. It is good to have a function. For example, if the start time of the barbecue party is 6:00 p.m., setting the time condition to be before 6:00 p.m. , if the start time of the barbecue party has passed, it is possible to prevent the notification of the barbecue party from being made.

Alternatively, the traffic manager can operate the system to notify the driver to bring the removable media to the traffic control department. For example, if image data or driving data that has not been transmitted to this system via a wireless transmission line remains in the on-vehicle device, the driver of the vehicle equipped with the on-vehicle device that has unsent data remains. It can be notified to bring the removable media to the operations management department.

If the system and the in-vehicle equipment are provided with a function that allows the operation manager who operates the system and the driver of the vehicle equipped with the in-vehicle equipment to interact via the in-vehicle equipment and the system, good. By using this dialogue function, the recipient of the message can immediately respond to the message sent from one of the operation manager and the driver to the other with high immediacy.

(17) A function to display a map in a window displayed on the screen, and change the scale of the map displayed in the window according to the change in the size of the window when the user changes the size of the window. , the system may further include:

Even if the size of the window is changed, the map of the desired range is displayed, so there is no need to adjust the scale of the map each time the size of the window is changed. When a part of the map is selected by operating the pointing device, it is preferable to have a function of enlarging and displaying the selected area. The user can easily enlarge and display an area that the user wants to see in detail. As the operation using the pointing device, for example, an operation of dragging with a mouse may be adopted.

One window is divided into multiple panes, and information with different attributes of the database is displayed in multiple panes. When the user selects one pane, the information displayed in that pane is displayed in one window. The system should have a function to enlarge and display. For example, when a variety of information is displayed on a large screen to a plurality of students at a venue such as a seminar, necessary information can be immediately enlarged and displayed so that the students can easily see it.

(18) A function of associating information indicating that an event has occurred in the vehicle with location information of the point where the event occurred, and storing the information in the database; The system may further include a function of obtaining the occurrence frequency of events in the partition for each partition using the database and displaying the event occurrence frequency for each partition.

The user can easily grasp the event occurrence frequency for each partition. As an event, for example, the occurrence of an accident, or a situation in which there is a high risk of an accident, such as sudden braking or drowsy driving, may be adopted. A plurality of divisions obtained by dividing a certain area on the map may be in the form of a square lattice (mesh), honeycomb, or the like. As a form of displaying the frequency of occurrence, it is preferable to use a histogram in which the horizontal axis corresponds to a plurality of sections. In this display mode, it is possible to easily compare the frequency of occurrence for each section. Moreover, it is preferable to provide a function for displaying a map and color-coding each section according to the frequency of occurrence. In this display mode, it is possible to easily grasp the area where the event frequently occurs on the map. It would be even better to have a function that displays the frequency of occurrence numerically on the map instead of color-coding.

When the user changes the scale of the map, it is preferable to have a function to change the size of each section according to the scale of the map. By reducing the scale of the map, it is possible to roughly grasp the distribution of event occurrence frequencies in a wide area. By selecting an area with a high event occurrence frequency and enlarging the scale, it is possible to grasp a more detailed distribution of the event occurrence frequency.

This system preferably has a function of dividing one window into a pane displaying a map and a pane displaying a list of search condition items. When the user operates a pane displaying a list of search condition items to specify a search condition associated with location information, for example, specifying a condition that a specific event has occurred, the data that satisfies the search condition is associated with the data. It is preferable to have a function to display a mark such as a pin or flag at a position on the map corresponding to the position information obtained. It is further preferable to have a function of displaying detailed information corresponding to the mark when the user operates the pointing device to select one mark on the map. For example, if you place the mouse cursor over a mark, the log data corresponding to that mark, such as acceleration data, velocity data, etc., will be displayed. It is even better if a function for displaying an image corresponding to the image, for example, a moving image, is provided.

(19) A system further comprising a function of connecting to the Internet, and a function of transmitting the contents of the database to the requesting site through a predetermined application programming interface when receiving a request to use the database from another site on the Internet. should be

The contents of the database of this system can be referred to via the Internet not only from the office where this system is installed but also from other servers. In particular, if the database is a document-oriented database, it becomes relatively easy to implement this function. Furthermore, since the database can be accessed from a server, personal computer, etc. that supports a predetermined application programming interface (WebAPI), if this interface is made public, an unspecified number of users will be able to access this database. . An unspecified number of users can freely create application programs to obtain desired information.

In addition, databases managed by other companies and databases managed by one's own company can be at least partially integrated via this Web API.

Even if the same vehicle is equipped with an event data recorder and a drive recorder as in-vehicle devices, and the system to which the data of the event data recorder is transmitted and the system to which the data of the drive recorder is transmitted are installed separately. good. Here, the event data recorder mainly means an in-vehicle device for recording vehicle information before and after a collision accident, and does not record image data. A drive recorder is an in-vehicle device that records images of the surroundings of a vehicle and data related to driving. A part of the data regarding the running state of the vehicle is redundantly recorded by the event data recorder and the drive recorder.

When the system for accumulating event data recorder data and the system for accumulating drive recorder data open their databases to the public through a predetermined application programming interface, one personal computer in which the application program is installed can be used to record events of one vehicle. Data recorder data and drive recorder data can be combined and handled. In order to combine the data of the event data recorder of one vehicle and the data of the drive recorder, the vehicle-mounted device identification information of the event data recorder mounted on the same vehicle and the vehicle-mounted device identification information of the drive recorder are prepared in advance. It is good to associate. This association information may be stored, for example, in a personal computer that accesses the two systems. If the automobile registration number is associated with the vehicle equipment identification information, two pieces of vehicle equipment identification information can be associated based on the vehicle registration number.

(20) The system may further include a function of connecting to the Internet and a function of transmitting data stored in the database to a blockchain.

Once registered in the blockchain, each block is given a time stamp, basically making it impossible to retroactively rewrite the data content, making it possible to prevent tampering with image data and driving data. If a dispute arises between the parties involved in a vehicle accident, the data registered on the blockchain can be useful information for resolving the dispute. A public type or consortium type blockchain can be used as a data storage destination blockchain.

When analyzing the cause of an accident, it would be even better to have a function to send information that is beneficial to the driver to the blockchain and not to transmit information that is unfavorable to the driver. The determination of whether it is advantageous or disadvantageous to the driver may be made by providing the present system with, for example, the function described in (21) below.

The in-vehicle device may be equipped with a function to transmit image data and driving data to the blockchain. In particular, the in-vehicle device should be equipped with a function that transmits information that is advantageous to the driver to the blockchain, and does not transmit information that is disadvantageous to the driver. By transmitting to the blockchain in real time while driving, it becomes easier to prove that there was no tampering, and it is possible to prevent disclosure of data that is disadvantageous to you.

Predetermined data may be extracted from the data acquired by this system or onboard equipment and transmitted to a public database other than blockchain.

(21) In elucidating the cause of an accident, the image data and the travel data stored in the database are data that is advantageous to the driver of the vehicle equipped with the in-vehicle device that acquired the image data and the travel data. It is preferable that the system further includes a function of determining whether or not the data is disadvantageous.

It is possible to easily extract and disclose only information that is advantageous to oneself in lawsuits concerning accidents or the like. Whether the information is advantageous or disadvantageous may be determined, for example, based on the traveling speed of the vehicle. In addition, traffic regulation information is registered in the database in advance, and it is equipped with a function to judge whether the information is advantageous or disadvantageous based on the presence or absence of traffic violations by comparing the registered traffic regulation information with driving data. Good. Furthermore, it has a function to extract traffic regulation information by analyzing image data and judge whether the information is advantageous or disadvantageous based on the presence or absence of traffic violations by comparing the extracted traffic regulation information with driving data. Be prepared. Furthermore, it is preferable to have a function of determining whether the information is advantageous or disadvantageous by analyzing image data and travel data before and after the accident. The system should be equipped with an artificial intelligence (AI) function for performing this analysis.

Information that indicates that the driver is traveling in compliance with traffic rules is determined to be information that is advantageous to the driver, and information that indicates that the driver is traveling in violation of traffic rules is determined to be information that is disadvantageous to the driver. Judgment is good. Image data indicating that the vehicle has stopped at a stop point may be determined to be information that is advantageous to the driver. Conversely, image data indicating that the vehicle did not stop at the stop point should be determined as information disadvantageous to the driver. The color of the traffic light is determined from the image data, and information indicating that the vehicle has entered the intersection despite the red light is preferably determined to be information disadvantageous to the driver. Conversely, information indicating that the vehicle has entered an intersection with a green light may be determined to be information advantageous to the driver.

For example, a video obtained from image data and a timeline indicating the period from the start to the end of the video and the point in time during playback are displayed on the screen of a personal computer. The system may be provided with the ability to recognizably display on a timeline the determined time period and the time period determined to be adverse information. For example, it is preferable to provide a function of displaying in red a period determined to be information unfavorable to the driver, and displaying in blue a period determined to be advantageous information.

The system should have a function of extracting only information that is beneficial to the driver and displaying it on the screen or printing it. It is even better if the information that is disadvantageous to the driver is encrypted so that a third party cannot easily access it.

It would be even better if this system had a function of extracting only information that is advantageous to the driver and automatically creating a statement of opinion to be submitted to the lawsuit when a lawsuit concerning an accident occurs. For example, "When we entered the intersection, the traffic light on our side was green.", "We were driving at the legal speed limit when the accident occurred.", "We stopped before the intersection." It is preferable to automatically generate sentences such as "." to create a written opinion.

(22) A function of displaying an image on a screen based on the image data stored in the database and attaching a memo or tag to the user who has viewed the image displayed on the screen, and a memo attached by the user. Alternatively, the system may further include a function of associating a tag with the image data and storing the tag in the database.

If a memo or tag is attached to an image while viewing it, the image to which the memo or tag is attached can be easily extracted later. For example, the image may be marked with a speech bubble, in which simple text information may be entered. For example, a speech bubble can be accompanied by text information such as "Watch out for this place". It is even better if frequently used text information is prepared in advance as tags and the user is allowed to select one from a plurality of tags. For example, a continuously recorded moving image (image data) may be segmented at fixed time intervals (e.g., 1 minute, 3 minutes, 5 minutes, etc.) and each segmented moving image may be stored in a database as one image file. Also, the event-recorded image data may be made into one image file for each event. It is preferable to have a function of attaching a memo or tag to each image file or event. It is even better to have a function of displaying a list of image files on the screen and displaying memos and tags attached to the image files in association with the image files. The user can easily locate image files with notes or tags.

It would be even better to have a function of specifying a point in time or a certain period from the start point to the end point of the moving image of one image file and adding a memo or tag in association with the specified point in time. In this way, the user can easily find a desired part to which a note or tag is attached from a certain length of moving image. For example, the user specifies a certain period of time, saying, "There were no accidents during this period.", "We were obeying the legal speed limit during this period." You can attach a note such as "Look at it." These notes and tags will be useful information for utilizing the database in the future.

(23) A function of storing, in the database, driver identification information that identifies the driver of the vehicle, a function of allowing the user to designate a specific driver, and the travel data associated with the driver designated by the user. from the database and output information about the extracted travel data.

Even if one driver changes cars, the driver can be used as a key to seamlessly integrate image data and travel data relating to the driver across multiple vehicles. For example, if one driver drives a truck back to the work site, drives a forklift at the work site, and then drives another truck from the work site to the destination of the load, the driver drives the truck. It would be desirable to be able to display information about driving data for a period of driving, driving a forklift, and then driving other trucks in a sequential flow. As a result, the operation manager can easily confirm how the work of one driver has changed over time.

A corporation that owns a plurality of vehicles may have a plurality of business establishments, and a vehicle usage pattern may be considered in which a vehicle is assigned to each business establishment and operation management of the vehicles is performed. In order to facilitate management of vehicles in such usage patterns, the database of this system should preferably have a function of storing office identification information for identifying the office to which the vehicle belongs. Furthermore, the system has a function of allowing the user to designate a specific office, and a function of extracting driving data associated with the office designated by the user from the database and outputting information on the extracted driving data. Good. Such a function of this system is convenient for managing the operation of vehicles for each office. For example, when three trucks and three forklifts belong to one office, the user can specify the office to specify three trucks and three forklifts belonging to the specified office. information on travel data with forklifts is readily available. Furthermore, if a surveillance camera is installed in the office, the image data acquired by the surveillance camera may be transmitted to the system. The system preferably has a function of associating the establishment identification information of the establishment where the surveillance camera is installed with the image data transmitted from the surveillance camera and storing them in the database.

(24) The database may be a system that is at least one of a relational database, a document-oriented database, and a graph database.

Since relational databases are highly versatile databases, they can be used for various purposes.

When using a document-oriented database, each column of the GPS log should be captured in JSON format, and the original data should also be captured in JSON format. The original data should also be searchable. For example, it is possible to easily perform a process of extracting only traveling data of 80 km/h or less.

When using a graph type database, it is preferable to store relationships among a large number of vehicles, drivers, places visited, places where unsafe driving is performed, etc. in a graph structure. This makes it possible to easily display drivers who have similar driving styles, vehicles and drivers related to dangerous places, and the like. It would be even better if it had a function to display the graph structure as a figure. This function can be effectively used to improve the efficiency of patrol work.

It is preferable to store the relationship between the biological information of the driver and the abnormality information (location, time, content of abnormality in behavior of the vehicle, etc.) in a graph database. By doing so, it becomes easier to visualize the relationship between the driver's biological condition and driving. The biological state of the driver may include, for example, information such as looking aside while looking at the head, dozing off based on how open the eyes are, driving posture, heart rate, and the like. The abnormality information may include, for example, information regarding the presence or absence of occurrence of lane departure, abnormal inter-vehicle distance, sudden braking, sudden start, and the like. Furthermore, it is preferable to store the result of the roll call in the database as driver information.

Instead of face-to-face roll call, IT roll call is permitted, which uses equipment approved by the Minister of Land, Infrastructure, Transport and Tourism to perform roll call remotely. For example, if an operation manager who is on standby at a business office uses wireless communication between this system installed at the business office and the on-board device to make an IT roll call, the system and the on-board device are equipped with a function. good. The system may have a function of inputting the result of the IT roll call to the operation manager, and a function of storing the input result of the roll call in the database as driver information. Further, the system may be provided with a function to perform image analysis based on the image data of the driver transmitted from the on-vehicle device to the system and to determine the health condition of the driver and the presence or absence of drunkenness. The system preferably has a function of storing the determination result in the database as information about the driver.

It is preferable that this system has a function of displaying time periods and places where personnel are insufficient by using a graph type database. Furthermore, based on this information, it is preferable to have a function of issuing a job advertisement.

(25) A function of receiving image data from a fixed camera that captures an image of a specific location, and storing the received image data in the database in association with a fixed camera identifier that identifies the fixed camera and information on the date and time when the image was captured; It is good to set it as the system further equipped.

The image data acquired by the fixed camera and the image data acquired by the in-vehicle equipment installed in the vehicle can be collectively managed in a database. For example, it is preferable to use a premises where trucks and forklifts run as a place to be imaged by the fixed camera. In some cases, it is possible to supplement an image of a blind spot of a fixed camera where a large truck is parked with image data captured by on-vehicle equipment such as a truck or a forklift. In-vehicle devices that are likely to capture images of places that are blind spots for fixed cameras can be narrowed down based on date and time information, location information, and the like.

(26) The system may further include a function of displaying a list of on-board devices to be managed together with the operating status of each on-board device.

A user such as an operation manager or a system manager can easily grasp the operation status of the in-vehicle device from the information displayed on the screen. The operating status displayed in the list includes, for example, the firmware version, update date, whether the firmware update is scheduled, whether there is an error log, the setting value for each setting item, the most recent image data acquisition date and time information, and the most recent driving data acquisition. Date and time information should be included. It is preferable that this system has a function that allows a user who sees this column to issue commands such as various settings of the in-vehicle device via the screen on which the list is displayed.

As the user attributes of the user ID used when the user logs into this system, it is preferable to provide "operation manager" and "system manager". The items to be displayed in the list may be different between when logging in with a user ID with an attribute of an operation manager and when logging in with a user ID with an attribute of a system manager. When logged in with a user ID with the attribute of an operation manager, items required for operation management are displayed, and when logged in with a user ID with the attribute of a system administrator, items required for system management etc.) should be displayed.

In this system, when a user logs in, it is preferable to change the contents of the screen display according to the user attributes of the logged-in user. For example, when there is a login with a user ID that has the attribute of an operation manager, it is preferable to display a screen that facilitates acquisition of information necessary for operation management. When there is a login with the user ID of the system administrator, it is preferable to display the screen so that information necessary for system management can be easily obtained.

Furthermore, it is preferable to provide "driver" as a user attribute of the user ID. The system should have a function to limit the image data and travel data that can be viewed when logging in with a user ID that has a driver's attribute to those acquired by the on-board equipment of the vehicle that the user drives. Furthermore, it is preferable that the system has a function of creating a daily report based on the data relating to the driver stored in the database when logging in with a user ID having attributes of the driver.

Furthermore, the system should have a function of recording an access log to data in the database. For example, it is preferable to have a function of recording the date and time when the data was accessed, the user ID, the data to be accessed, and the like. The access log can be used for auditing when falsification of data is found. The access log can also be used as evidence to prove that the data has not been tampered with when investigating an accident.

(27) The program may be a program for causing a computer to implement any of the system functions of (1) to (26) above.

The functions of this system can be implemented on a personal computer or server on which this program is installed.

(28) Transmitting image data acquired by an imaging device mounted on a vehicle and driving data representing the driving state of the vehicle via a wireless transmission line, and transmitting the image data during a period when wireless communication is not possible; and an in-vehicle device having a function of recording the traveling data and transmitting at least part of the recorded image data and the traveling data via a wireless transmission line when wireless communication becomes possible. do it.

In the method of transferring driving data and image data from on-vehicle equipment to an external device via removable media, it is necessary to carry the removable media. With this in-vehicle device, driving data and image data transmitted via a wireless transmission line can be handed over to an external device without carrying removable media. Some of the traveling data and image data obtained while traveling in an area where wireless communication is not possible can be transferred to an external device via a wireless transmission line. This saves the trouble of handing over travel data, image data, and the like. A drive recorder, for example, may be used as the in-vehicle device. The data transmission destination may be the system described in any one of (1) to (26) above.

The image data may include data of at least one image such as an image in front of, behind, or to the side of the vehicle, or an image inside the vehicle. The travel data includes, for example, position information (such as GPS data), date and time information, speed information, acceleration information (such as information indicating the magnitude of impact), and information representing operations performed on the vehicle (such as braking, accelerator operation information, steering information, etc.). The period during which wireless communication is not possible includes the period during which the vehicle is traveling outside the wireless communication available area, the period during which wireless communication is disabled due to a failure in the wireless communication system, and the like.

The data to be transmitted when wireless communication becomes possible may be determined based on the data processing speed of the in-vehicle device, the communication speed of the wireless transmission line, and the like. For example, if the data processing speed and communication speed are sufficiently high, all image data and travel data should be transmitted. If the data processing speed and communication speed are not sufficient, it is preferable to transmit only part of the image data and travel data. The type of data to be transmitted should be set in the vehicle-mounted device in advance.

In addition to the in-vehicle equipment, other imaging devices such as surveillance cameras in fixed locations may be provided with a function to transmit data to an external device via a wireless transmission line. In this case, data corresponding to travel data should not be transmitted, and image data, device identification information, date and time information, etc. should be transmitted. When data cannot be transmitted due to a failure in the wireless transmission path, it is preferable to have a function of recording image data and the like in a storage device such as a removable medium mounted on the imaging device. It is preferable to have a function of transmitting at least part of data such as recorded image data via a wireless transmission path when wireless communication becomes possible.

(29) During a period when wireless communication is not possible, the image data and the driving data are recorded on a removable medium, and when wireless communication becomes possible, the driving data recorded on the removable medium is transmitted via a wireless transmission path. It is preferable that the in-vehicle device further includes a function of transmitting the image data recorded on the removable medium and not transmitting the image data recorded on the removable medium.

Normally, the amount of image data is much larger than the amount of travel data. By not transmitting image data after wireless communication has become possible, even if there is not enough margin in the transmission speed, wireless communication was not possible without stopping the transmission of image data and driving data acquired at the present time. Running data for the period can be transmitted.

For example, if wireless communication is unavailable for about one hour, about 8 GB of image data is accumulated during this period. Removable media such as SD cards are not good at simultaneously writing and reading data. It is difficult to read the image data written during the period when wireless communication was not possible while writing the image data currently being collected to the removable medium. Furthermore, it is difficult to transmit about 8 GB of image data along with the image data currently being collected through a wireless transmission line. In such a case, it is possible to prevent the loss of the traveling data by transmitting the traveling data collected during the period when wireless communication was not possible. The image data that could not be transmitted should be read by an external device via a removable medium or the like.

The travel data to be sent to the external device should include the items specified in the technical standards for digital tachographs (digital operation recorders). For example, time information, instantaneous speed information, mileage information, identification information for specifying the vehicle, etc. may be included. As a result, this in-vehicle device can be used as a substitute for a digital tachograph. Also, it is preferable to transmit the time during which the engine is turned off to an external device. Then, the operation manager can easily know the rest time of the driver from the external device.

The external device that collects such information from the on-vehicle equipment preferably has a function of displaying daily, weekly, and monthly mileage for each driver and each vehicle. Further, it would be even better if a user using an external device could specify the period for totaling the traveled distance.

The in-vehicle device preferably has a function of reading the driver's license information and recording the information identifying the driver who will be driving from now on in association with the image data and the driving data. Alternatively, the in-vehicle device has a function of capturing an image of the inside of the vehicle, and has a function of identifying the driver by analyzing the image of the driver reflected in the image inside the vehicle, for example, performing face recognition. Even better.

(30) The in-vehicle device may further include a function of transmitting at least one of the information on the connection status and the operating status via the wireless transmission path.

A user of the external device can know the connection state with the vehicle-mounted device via the wireless transmission path or the operating state of the vehicle-mounted device. For example, when the in-vehicle device is not connected to an external device, the in-vehicle device is not operating because the vehicle engine is turned off. , and states where communication is not possible due to failure of on-vehicle equipment, etc. When communication becomes possible, the vehicle-mounted device should have a function of transmitting information such as the time when the engine is turned on and off, the time when the radio wave becomes weak and communication is disabled, and the time when the communication is restored. Furthermore, as the operating state of the in-vehicle device, it is preferable to transmit information indicating whether or not image data and travel data are being recorded normally.

The in-vehicle device preferably records the history of the connection state and operation state, and transmits information representing the current connection state and operation state to the external device in real time. The external device preferably has a function of notifying the user of the information received in real time indicating the connection state and operation state. A user who uses an external device can know the operating state of the in-vehicle device in real time. In particular, when the operating state of the vehicle-mounted device is abnormal, it is preferable to notify the user immediately. A user who notices the abnormality can take some action to avoid trouble. For example, if errors have frequently occurred in the imaging device in the past, it is possible to take measures such as replacing the imaging device. In addition, if writing errors to removable media have occurred frequently in the past, it is possible to take measures such as replacing the removable media.

(31) a function of sequentially overwriting and recording the image data on a removable medium; storing the number of times the removable medium has been overwritten in an overwrite counter secured in a storage area of the removable medium; The in-vehicle device may further have a function of transmitting values via a wireless transmission path.

In general, repeated overwriting of removable media degrades the removable media, making it more likely that write errors will occur. The user of the external device that receives the overwrite counter value can predict when the removable medium will be replaced by checking the overwrite counter value. The external device should have a function of notifying the user of the number of remaining overwrites.

The in-vehicle device should have a function to take over the value of the overwrite counter before and after formatting the removable media. For example, the in-vehicle device may read the value of the overwrite counter before formatting, and write the value before formatting to the overwrite counter after formatting. By providing a function to take over the value of the overwrite counter, the user can save the trouble of performing an operation to take over the value of the overwrite counter when formatting the removable medium.

(32) An in-vehicle device further comprising a function of detecting an event that has occurred in the vehicle, and a function of notifying an external device of the occurrence of the event via a wireless transmission line when the occurrence of the event is detected. should be

A user of the external device can know that some event has occurred in the vehicle. The in-vehicle device should preferably notify the occurrence of the event in real time. This allows the user of the external device to notice the occurrence of the event at an early stage.

(33) a second period from before the first period to the start of the first period than the information amount of the image data in the first period from before to after the event occurrence time; and The vehicle-mounted device may reduce the information amount of the image data in the third period starting from the end of the first period and transmit the image data via a wireless transmission path.

The amount of data to be transferred can be reduced compared to the case where the information amount of the image data in the second period and the third period is equal to the information amount of the image data in the first period. Here, "information amount" means the amount of information per unit time. Since the amount of information in the image data in the first period is large, it is possible to provide sufficient information to search for the cause of an event such as an accident. Furthermore, the image data of the second period before and after the first period or the third period can also be used to search for the cause of event occurrence.

To reduce the amount of information in the image data in the second and third periods, for example, at least one of the resolution and frame rate should be lower than the resolution and frame rate of the image data in the first period. In addition, it is preferable that the compression rate of the image data in the second period and the third period is higher than the compression rate of the image data in the first period.

It is preferable that the external device and the vehicle-mounted device have a function of controlling the vehicle-mounted device from the external device and setting the lengths of the first period, the second period, and the third period. This function is preferably implemented by transmitting a command signal from an external device to the vehicle-mounted device via a wireless transmission line. Also, it is preferable that the length of the period can be set for each type of event. The types of events may include, for example, types such as acceleration (impact) applied to the vehicle exceeding a specified value, speed change exceeding a specified value, and air bag operation. When the user operates the external device to set the length of this period, the function to display the communication charge per event for the length of the period to be set is provided by the external device. be prepared for It is even better to have a function of displaying the occurrence frequency of past events and displaying the communication charges incurred in a certain period of time (for example, one month) when events occur with the same frequency.

Furthermore, the function of controlling the on-vehicle device from an external device and setting the value of the setting item regarding the amount of information of the image data for the first period, the second period, and the third period may be provided by the external device and the on-vehicle device. Equipment should be prepared. The setting items may include resolution, frame rate, compression rate, and the like. The external device preferably has a function of displaying a sample image to allow the user to confirm how the image is actually reproduced when the user sets the value of the setting item to be set.

The in-vehicle device preferably has a constant recording function for constantly recording images and an event recording function for recording images when an event occurs. For example, if the acquired image data is temporarily recorded in the cyclic memory area of the RAM, read out from the cyclic memory area, image-processed for constant recording and event recording, and constant recording and event recording are performed. good. Here, image processing means processing for converting original image data so as to have the resolution, frame rate, and compression rate for constant recording and event recording.

Two video streams, a detailed image with a large amount of information and a rough image with a small amount of information, may be created and recorded in different areas of the RAM. The image data for the first period is read out from the area where the detailed image is recorded, and the image data for the second and third periods is read from the area where the coarse image is recorded and is transmitted to an external device. do it.

(34) The in-vehicle device may further have a function of outputting the received message by voice or displaying it on the screen when the message is received from an external device via a wireless transmission line.

A user of an external device, such as an operations manager, can provide messages to the vehicle operator. It is even better if the function described in item (16) above is provided.

(35) The in-vehicle device may further include a function of analyzing the image data, recognizing characters contained in the image data, converting the character information into voice, and outputting the voice.

The driver can notice that there is a character signboard or the like that he did not notice while driving. For example, when there is information about a destination, for example, a guide signboard that says, "Turn right after XX, 200 m", the driver can notice that he should turn right even if he misses the guide signboard.

For example, when character information about a facility such as a store, hospital, or public facility is found by image analysis, the in-vehicle device accesses the Internet, searches for the address of the facility, and connects with the car navigation system to locate the facility as the destination. It is preferable that the in-vehicle device and the car navigation system are provided with the function of setting to .

For example, when driving from Okazaki on National Route 1 toward Toyohashi, you will notice a sign that says "Baby Brush Center". It is preferable to recognize the characters on this signboard, automatically search through the Internet, and read out the search results using a text-to-speech (TTS) function. At this time, from the search results, it recognizes the closest thing to the current location, the direction indication and the distance indication on the signboard, extracts the things within the range and direction from the current location, and reads out only the extracted search results. It is better to

For example, there are "Baby Brush Centers" in Tokyo, Kawaguchi, Nagoya, and Toyokawa. If you recognize the signboard of "Baby Brush Center" while driving in the direction of Toyohashi in Miai, you can read out the contents of the web page of the nearest Toyokawa Baby Brush Center in the direction of travel. good. If you recognize a string of digits corresponding to a phone number on a sign, you can search with that phone number.

At the end of voice output, a voice asking the driver whether or not to set the recognized facility as the destination, for example, "Would you like to set this place as the destination?" It is preferable to have a function to wait for an answer by When the driver gives an affirmative answer to set the destination, the in-vehicle device interlocks with the car navigation system so that the car navigation system sets the facility as the destination and starts route guidance. do it.

In particular, a function that analyzes the image of the driver in the image, recognizes the line of sight of the driver, and gives priority to the explanation of the signboard when it is recognized that the driver is gazing at the signboard ahead of the line of sight. , the in-vehicle equipment should be provided.

In particular, when automatic driving is realized, the driver will be released from the driving operation and will be idle. For example, research is being conducted on games that replace the scenery from the vehicle with a virtual world, move in the virtual world according to the movement of the vehicle, and make monsters appear in the virtual world when the traffic light turns red. . In such a game, it is preferable to use an automatic read-aloud function by voice.

It is even better if a function to cancel this function is provided. For example, when driving on a road with a large number of signboards installed, canceling this function can prevent frequent unnecessary voice outputs from interfering with driving.

Character signs to inform drivers that automatic speed control devices and mobile orvis are installed, for example, recognize the character "automatic speed control" among character signs such as "route with automatic speed control device installed" Therefore, the in-vehicle device should be equipped with a function to generate an alarm or a function to generate an audible warning. Based on the rule of the Supreme Court decision in the Kyoto Gakufuren Incident, ``No one has the freedom to not have his or her face photographed without permission. , is installed in front of the control machine. Small, portable mobile orvis also take pictures automatically, so similar text signs are installed based on this norm. Therefore, by issuing an alarm or warning to the driver based on the existence of this character sign, it is possible to motivate the driver to obey the traffic rules before the location where the automatic speed control device is installed.

If the in-vehicle device has a POI file of the installation location of the automatic speed control device, and the installation location of the automatic speed control device is within a predetermined distance (for example, 2 km) of the route on which the vehicle is currently running, the POI file Only warnings or warnings based on text signs should be issued, and warnings or warnings based on text signs should not be issued. For fixedly installed speed control devices, issuing an alarm or warning based on the POI file is sufficient. However, a POI file cannot be created in advance for a temporary installation such as a mobile orbis. Therefore, mobile orvis should be configured to issue an alarm or warning by recognizing the text sign.

Character signs to notify the installation of the automatic speed control device are installed in two places up to the point where the automatic speed control device is installed. It is preferable that the alarm or warning when the character sign is recognized for the second time be stronger than the alarm or warning when the character sign is recognized for the first time. For example, an alert or warning that is more noticeable to the driver may be issued. If the vehicle deviates from the installation location of the automatic speed control device by turning right or left, it is preferable not to issue an alarm or warning. Since the detection of speed by the automatic speed control device is performed by emitting radar or laser toward the vehicle, a function to detect (catch) the signal of this radar or laser is provided, and when these signals are detected , should be provided with a function to issue a stronger alarm or warning. It is preferable to provide a function for notifying the driver that the vehicle has passed through a location where these signals are detected.

Furthermore, in the zone 30 area, when issuing an alarm or warning due to recognition of a sign, it is preferable to issue a stronger alarm or warning.

An in-vehicle device may be mounted on a vehicle or device such as a forklift, a hoist, or a crane that performs cargo handling work, and the in-vehicle device may be provided with a function of reading marks such as barcodes attached to cargo. Furthermore, it is preferable to have a function of recognizing characters attached to the package in addition to the mark. A package can be specified by reading a mark or characters (hereinafter referred to as package identification information) attached to the package. This information can be used for cargo handling work.

It is preferable to mount a celestial camera (360-degree camera) or a plurality of cameras for imaging the surroundings on the cargo handling vehicle or cargo handling device. The in-vehicle device should be equipped with a function of reading the baggage identification information given to the surrounding baggage from the images captured by these cameras by image recognition, and identifying the location where the baggage to be transported is stored. It is even better to have a function of displaying on the display screen the location (relative direction and position with respect to the own vehicle) where the cargo to be transported is stored.

For example, assume that a cardboard box of Mikkabi oranges is placed in front of the first forklift in a warehouse, a cardboard box of Unshu oranges is placed behind it, a cardboard box of Aoshima oranges is placed on the right, and a cardboard box of Ponkan is placed on the left. Each cardboard box is provided with a barcode for identifying the contents. Through wireless communication, the on-vehicle device of the first forklift receives information that it is necessary to load 15 cardboard boxes of Qingdao mandarin oranges, which are currently being shipped from the warehouse, onto the No. 5 truck of Company A, which is located alongside the No. 1 loading area. sent. The in-vehicle equipment of the first forklift is connected with communication functions such as LPWA and WiFi, four cameras on the front, back, left and right, and a display. Information such as "product name: Qingdao mandarin orange", "quantity: 15", "location: No. 1 loading area", and "truck: A's No. 5 truck" are displayed on the display, and four cameras Image recognition is performed to determine whether any of the captured images has a barcode indicating “Qingdao mandarin orange”. In this example, it recognizes that there is a barcode of "Aoshima oranges" in the image of the camera capturing the right side, and displays the information "The object to be transported is Aoshima oranges on the right side." The same content is notified by voice. On the display, for example, the direction of the object to be loaded may be indicated by an arrow, or the range in which the object to be loaded is captured among the images of the four cameras may be conspicuously displayed. For example, by recognizing the area where the object to be transported is shown in the real-time image of the in-vehicle device (identifying the cardboard box with the Qingdao mandarin orange barcode and recognizing its range), a translucent red Hatching should be added.

I explained an example of a kind of thing like a mandarin orange (any cardboard box of that kind is fine), but the object to be transported is a specific thing (such as a mail order package addressed to Mr. A). This function is particularly useful in the case of , since the appearance of the box does not allow one to recognize that particular package. For example, the above function is particularly useful when packages addressed to companies A, B, C, and D have the same appearance but different contents.

It is preferable to have a function of counting the number of cardboard boxes that have been transported and reporting the number of remaining cardboard boxes to be transported. It would be even better to have a function to issue a notification to that effect when it is likely to carry too much. It would be even better to have a function of navigating the traveling route within the premises from the place where the cargo to be transported is to the transport destination. When the object to be transported is placed on the fork of the forklift, loaded on the truck, unloaded from the fork, and unloaded from the truck, the transportation status of the cargo is recorded in the office server, cloud database and blockchain. It is preferable to have a function to

Instead of attaching package identification information to packages, it may be assigned to pallets and racks. As the parcel identification information, for example, a two-dimensional code or other various codes may be used in addition to the bar code.

(36) The in-vehicle device may further have a function of communicating with an RFID tag, reading information stored in the RFID tag, and storing the reading result in a storage device.

It is thought that a system like Amazon Go will appear in the future that does not require a cash register when shopping, and the payment is automatically completed just by picking up the product from the shelf and leaving the store. For example, by 2025, it is planned that RFID tags will be attached to all products at convenience stores (attached at the time of product manufacture). By reading the RFID tag attached to the product, information on the product purchased by the vehicle occupant and brought into the vehicle can be stored in the in-vehicle device. For example, it is possible to create a list of purchased products.

It is preferable to construct a system having a function of installing a camera at the entrance of the store and photographing the purchaser when the purchaser passes through the RFID reading gate. The system may be provided with a function of determining the age and sex of the purchaser from the image of the purchaser, and recording the information on the age and sex of the purchaser in association with the sales record of the product.

At convenience stores, payment confirmation buttons on the register are arranged by age and gender, and the store clerk judges the purchaser's age and gender based on the purchaser's appearance (appearance) and presses one of the payment confirmation buttons. , enter the purchaser's age and gender information. By automatically determining the purchaser's age and sex from the purchaser's image, it is possible to save the work of the store clerk. In addition, it is possible to more objectively determine the age and gender by eliminating subjectivity of the store clerk.

In addition to the age and gender of the purchaser, the type of clothing (work clothes, school uniforms, suits, etc.) and group type (single, couple, family, with children, etc.) are automatically determined and recorded in association with the sales record of the product. It would be even better if it had a function to This system may determine the presence or absence of companions from people who entered and exited the gate in close temporal proximity, and determine the group type based on this determination result.

When a plurality of purchasers carrying commodities pass through the RFID reading gate at the same time, it becomes impossible to determine which purchaser should be charged for which commodities. Therefore, in principle, only one person can pass through the RFID reading gate at a time. Therefore, as described above, it is possible to determine the presence or absence of companions from people who entered and exited the gate in close time proximity.

It is preferable to provide a function of counting people who pass through the RFID reading gate during the period from reading of the RFID tag to reading of the next RFID tag as one group. In addition, an upper limit is set for the time interval to be counted as one group, and if multiple people pass through the gate in a time interval that exceeds this upper limit, these multiple people are not counted as the same group. and even better.

It would be even better if a camera was installed in the parking lot of the store and provided with a function of determining people who got into the same vehicle as one group. With this function, it is possible to improve the accuracy of determining a plurality of people as one group.

It is preferable to have a function to transmit the recognition result of the purchaser and companion to a server on the cloud or to store it in a local server installed in the store.

(37) The program may be a program for causing a computer to realize the functions of the in-vehicle device described in (28) to (36) above.

When transferring image data and driving data from in-vehicle equipment to this system, it is possible to reduce the trouble of carrying removable media and to effectively use various data other than when an event occurs.

The effect of the invention of the present application is not limited to this, and the effect produced by the parts of the configuration disclosed in the specification and drawings, etc. is also disclosed, and the configuration that produces the effect is also acquired by divisional application, amendment, etc. have the intention to For example, in this specification, the description of "can be done" is a description that clearly shows the effect, and there are parts showing the effect even if there is no description of "can be done". Moreover, even without such a description, there is an effect that can be grasped by the configuration.

[First embodiment]
A server (system) according to the first embodiment will be described with reference to FIG.
FIG. 1 is a block diagram showing the functions of a server 40 according to the first embodiment, and a schematic diagram of devices connected to the server 40. As shown in FIG. The server 40 includes a transmission/reception unit 41, a database management unit 42, an image analysis unit 43, a current position analysis unit 44, an SD card reading unit 45, an input/output unit 46, an API unit 47, an advantage/disadvantage determination unit 48, and a database 50. . The functions of these units are realized by the personal computer executing programs. A relational database is employed for the database 50 . Since relational databases are highly versatile databases, they can be used for various purposes.

A plurality of access points 35 constructing a WiFi standard wireless LAN are connected to a server 40 via a wired LAN 37 . A communicable area 36 is defined for each access point 35 . A wireless transmission path 32 is established between a drive recorder 30 mounted on each of a plurality of vehicles 31 and an access point 35 . The drive recorder 30 of the vehicle 31 located within the communicable area 36 and the transmission/reception unit 41 of the server 40 perform data communication via the wireless transmission line 32 and the wired LAN 37 . Vehicles 31 equipped with the drive recorder 30 include, for example, passenger cars, trucks, and buses that run on general roads, special vehicles such as forklifts that run on specific premises, streetcars that run on tracks, and trains that run on railroads. etc.

The input/output unit 46 controls input/output devices 60 including input devices such as keyboards, pointing devices, and touch panels, and output devices such as printers and display screens.

The drive recorder 30 transmits vehicle-mounted device identification information for identifying the drive recorder, image data acquired by the drive recorder 30, and driving data representing the driving state of the vehicle 31 via the wireless transmission path 32 and the wired LAN 37. Send. The database management unit 42 creates a database 50 by associating the in-vehicle device identification information, the image data, and the travel data received from the drive recorder 30 with each other. Furthermore, the database management unit 42 searches the database 50 based on the search conditions specified by the user, and outputs the search results to the input/output device 60 .

An instruction from the user is given from the input/output section 46 to the database management section 42 by the user operating the input/output device 60 . The search result is displayed on the display screen or the like of the input/output device 60 when the database management unit 42 gives a display command to the input/output unit 46 .

The image analysis unit 43 performs image analysis on image data received from the drive recorder 30 . The database management unit 42 stores the analysis result of the image analysis unit 43 in the database 50 in association with the image data. By performing image analysis, the image analysis unit 43 determines whether or not an accident has occurred around the own vehicle 31, whether or not a situation corresponding to a near-miss event has occurred even though the accident did not occur, and whether or not the traffic light is displayed on the image. whether a pedestrian is reflected in the image; whether a predetermined road sign is reflected in the image; whether a vehicle is reflected in the image; If so, determine the exterior features of the vehicle. Information such as vehicle color, vehicle classification, and license plate is used as the external features of surrounding vehicles. The vehicle category includes buses, trucks, passenger cars, motorcycles, and the like. The analysis result is converted into text data, coded, or flagged by the image analysis unit 43 and handed over to the database management unit 42 . The database management unit 42 stores the text data, coded, or flagged analysis results in the database 50 .

The travel data includes current position information of the vehicle 31 equipped with the drive recorder 30. After receiving the travel data from the drive recorder 30, the current position analysis unit 44 analyzes the current position of the vehicle 31 based on the current position information. Classify the current position of into one of multiple groups. The database management unit 42 associates the travel data with information on the group to which the current position belongs, and stores them in the database 50 .

As a plurality of groups for classifying the current position, the map is divided into a plurality of divisions with a mesh, and the divided divisions are adopted. The size of the partition is, for example, a square with a side length of 50 m to 100 m. In this case, a point existing in a belt-shaped area of constant width including the boundary line of the division belongs to two divisions on both sides of the boundary line. As a result, even when the search target point is located very close to the boundary line, it is possible to avoid missing necessary data in the search.

The SD card reader 45 controls reading of data from the SD card attached to the drive recorder 30 . The database management unit 42 reads, via the SD card reading unit 45, vehicle-mounted device identification information, image data, and travel data recorded on the SD card. Further, the database management unit 42 stores in the database 50 the in-vehicle device identification information, the image data, and the travel data read from the SD card.

The server 40 has a function of connecting to the Internet 70 . When the API unit 47 receives a request to use the database 50 from another site 71 on the Internet 70, it transmits the contents of the database 50 to the requesting site 71 using a predetermined application programming interface (API). Furthermore, the database management unit 42 has a function of transmitting data stored in the database 50 to the blockchain.

The advantage/disadvantage determination unit 48 determines that the image data and travel data stored in the database 50 are advantageous to the driver of the vehicle 31 equipped with the drive recorder 30 that acquires the image data and travel data in clarifying the cause of the accident. determine whether the data are favorable or unfavorable.

Next, the determination method will be described. The advantage/disadvantage determination unit 48 makes determinations based on vehicle travel data and image data. The advantage/disadvantage determination unit 48 compares the traffic rule information registered in the database 50 or the traffic rule information obtained from the analysis result of the image data with the driving data to determine whether or not there is a traffic violation. If there is no traffic violation, the information is judged as advantageous information. For example, image data indicating that the vehicle has stopped at a stop point is determined to be useful information for the driver. Conversely, image data indicating that the vehicle did not stop at the stop point is determined to be information disadvantageous to the driver. The color of the traffic light is determined from the image data, and information indicating that the vehicle has entered the intersection despite the red light is determined to be information disadvantageous to the driver. Conversely, information indicating that the vehicle has entered an intersection with a green light is determined to be information advantageous to the driver. Further, the advantage/disadvantage determination unit 48 analyzes the image data and travel data before and after the accident to determine whether the information is advantageous or disadvantageous. The advantage/disadvantage determination unit 48 is equipped with an artificial intelligence (AI) function for performing this analysis.

Next, the excellent effects of the first embodiment will be described.
In the first embodiment, when transferring image data and driving data from the drive recorder 30 to the server 40, it is possible to reduce the trouble of carrying an SD card and to effectively use various data other than when an event occurs. become. By displaying the results of searching the database based on the search conditions, the user can easily find the necessary data from the database containing a huge amount of data. Here, the user includes a vehicle driver, an operation manager who manages the operation of the vehicle, and a system administrator who manages the server 40 . Note that the operation manager may also serve as the system manager.

The image analysis result by the image analysis unit 43 is converted into text data, coded, or flagged and stored in the database 50, so that the image analysis result is used as a search key without image analysis at the time of searching the database 50. be able to. As a result, search speed can be increased. For example, if it is desired to know the running state of a red passenger car at a certain place during a certain time period, the analysis results regarding the vehicle color and vehicle classification can be used. Further, by using the analysis result regarding the presence or absence of an accident, it is possible to easily search whether or not the image of an accident that occurred at a certain place on a certain date is stored in the database 50 or not. If an image of the accident is stored in the database 50, this image provides useful information for identifying the cause of the accident.

Since the current position analysis unit 44 classifies the current position of the vehicle 31 into one of a plurality of groups, by searching the database 50 using the group as a search key, compared to searching by the latitude and longitude of the position of the vehicle. can be used to quickly and coarsely search based on vehicle location.

Since the server 40 has an SD card reading unit 45, the data recorded on the SD card during the period when communication via the wireless transmission line 32 was not possible, and the data recorded on the SD card by the drive recorder 30 without a wireless communication function. Such data can be stored in the database 50 . By storing in the database 50 the data of the period during which the wireless transmission line 32 was unable to communicate, the image data and the travel data can be stored in a database without a break in time. By importing data from the drive recorder 30 that does not have a wireless communication function, the database 50 can be further enriched.

The database management unit 42 provides the information of the database 50 to other sites on the Internet via the API unit 47, so that not only the office where the server 40 is installed but also from other servers etc. via the Internet It becomes possible to refer to the contents of the database 50 . Furthermore, since the database 50 can be accessed by a server, personal computer, or the like that supports a predetermined application programming interface (WebAPI), if this interface is open to the public, an unspecified number of users can access this database 50. become. An unspecified number of users can freely create application programs to obtain desired information. In addition, databases managed by other companies and databases managed by one's own company can be at least partially integrated via this Web API.

Once the data in the database 50 is registered in the blockchain by the database management unit 42, each block is given a time stamp, and basically the contents of the data cannot be retroactively rewritten. Therefore, falsification of image data and travel data can be suppressed. If a dispute arises between the parties involved in a vehicle accident, the data registered on the blockchain can be useful information for resolving the dispute. A public type or consortium type blockchain can be used as a data storage destination blockchain.

In the first embodiment, the advantage/disadvantage determination unit 48 determines whether the data is advantageous or unfavorable to the driver. Therefore, it is possible to easily extract and disclose only information that is advantageous to the driver in a lawsuit concerning an accident or the like. can be done.

[Modification of the first embodiment]
Next, a modification of the first embodiment will be described.
In the first embodiment, a wireless LAN is used as the wireless transmission line 32 between the access point 35 and the drive recorder 30, but in the modified example, a mobile communication network provided by a telecommunications carrier is used instead of the wireless LAN. (for example, LTE standard transmission line) is used. A wireless transmission line may be used as the transmission line between the access point 35 and the server 40 instead of the wired LAN 37 .

It is preferable to determine whether to use a mobile communication network or a wireless LAN as a wireless transmission path according to the moving range of the vehicle 31 whose data is to be collected. For example, when collecting data from a drive recorder 30 mounted on a vehicle such as a forklift that moves within a specific premises, a wireless LAN may be used. The number of wireless LAN access points 35 may be determined according to the size of the area to be covered by the wireless transmission line and the hierarchical structure. A mobile communication network may be used to collect data from vehicles that travel over a wide area that cannot be covered by a wireless LAN, such as long-distance trucks and taxis. Data may be transmitted from the drive recorder 30 to the server 40 using both the mobile communication network and wireless LAN wireless transmission paths. In this case, when the vehicle is located within the communicable range of the wireless LAN, communication is preferably performed via the wireless LAN, and otherwise, communication is performed via the mobile communication network.

A drive recorder 30 installed in a vehicle that may travel outside the wireless LAN communication area detects whether the current position is within the wireless LAN communication area based on the current position information acquired by GPS or the like. It has a function to determine whether or not it is within the communication area and search for an access point. When GPS radio waves cannot be received and current position information cannot be obtained (during non-positioning), the drive recorder 30 has a function of periodically searching for an access point 35 at regular intervals.

Basically, the drive recorder 30 mounted on a vehicle that performs work within a premises where wireless LAN communication is possible always searches for an access point 35 . When the access point 35 cannot be detected, the process of searching for the access point 35 is repeatedly executed (retryed). The server 40 has a function of setting the number of retries or the retry cycle in correspondence with the non-detection time. For example, the longer the non-detection time, the longer the retry period. For example, when the non-detection time is 10 minutes or less, the retry period is set to 5 seconds, and when the non-detection time is 10 minutes to 1 hour, the retry period is set to 2 minutes. When the non-detection time exceeds a predetermined upper limit value, for example, one hour, the server 40 detects the overtime and has a function of notifying the operation manager. The drive recorder 30 has a function of changing the correspondence relationship between the non-detection time and the retry period depending on the installation status of the access point 35 or the like.

If a mobile communication network is used as the wireless transmission line, the drive recorder 30 should always search for the access point 35 . When the access point 35 cannot be detected, the process of searching for the access point 35 should be repeatedly executed (retryed). As in the case of using a wireless LAN, the server 40 preferably has a function for setting the number of retries or the retry cycle in correspondence with the non-detection time.

The in-vehicle device identification information is information for specifying one drive recorder 30 among the plurality of drive recorders 30 . When one drive recorder 30 is fixedly mounted on one vehicle 31 and cannot be remounted among a plurality of vehicles, the vehicle 31 can be identified by the on-vehicle device identification information. Furthermore, when the correspondence between the vehicle and the driver is fixed, the driver can be identified by the in-vehicle equipment identification information. When the drive recorder 30 is remounted and used among a plurality of vehicles, vehicle identification information for identifying the vehicle 31 may be added to the information transmitted to the server 40 . Furthermore, if there is a possibility that a plurality of drivers will drive one vehicle 1, it is preferable to add driver identification information for identifying the drivers to the information transmitted to the server 40. FIG. When the SD card is attached to the drive recorder 30 and operated, it is preferable to add media identification information for identifying the SD card to the information transmitted to the server 40 . When the driver carries and uses a specific SD card, the media identification information can be used as information for identifying the driver.

Image data acquired by the drive recorder 30 may include, for example, image data in front of the vehicle 31 . It is even better to include at least one of rear, side, and interior image data. By including image data such as the rear of the vehicle 31, more information can be collected. This image data may be moving image data, for example. By collecting moving image data, it is possible to obtain information about motion that cannot be obtained from still images. Data may be transmitted from the drive recorder 30 to the server 40 all the time, not only when a specific event such as an accident occurs in the vehicle 31, but during a period when communication via the wireless transmission line 32 is possible. As a result, various kinds of information other than when an event occurs can be stored in a database.

The travel data may include, for example, date and time information, position information, speed information, acceleration information, event occurrence factor information, driver's operation information, and the like. The date and time information represents the date and time when the image data was captured. Latitude and longitude information acquired by a global positioning system (GPS) receiver, for example, may be used as the position information. For example, the drive recorder 30 may acquire the speed information from the vehicle via an in-vehicle network such as CAN. Acceleration information may be acquired from a three-axis acceleration sensor that measures longitudinal, vertical, and lateral acceleration mounted on the drive recorder 30 .

As search conditions instructed by the user, for example, information regarding date and time or period, information regarding position, vehicle identification information, driver identification information, event occurrence factors, etc. may be employed. The positional information may be, for example, latitude and longitude, name of a specific intersection, distance from the intersection, address, information indicating a specific division when a certain area is divided into a plurality of divisions, and the like. In order to allow the user to specify a specific point such as latitude and longitude, a map is displayed on the screen of the input/output device 60, and a specific point on the displayed map is pointed by the pointing device (for example, a mouse, etc.) of the input/output device 60. It is preferable to let the user specify the setting using a touch panel, etc.). For the display of search results, for example, a map format, a list format, or the like may be adopted.

Examples of event occurrence factors include acceleration (magnitude of impact applied to the vehicle) exceeding a threshold value, vehicle running speed exceeding the legal speed limit, and an occupant performing an event recording operation on the drive recorder 30. factors such as driving conditions. The information indicating the legal speed limit may be obtained, for example, by analyzing the image in front of the vehicle and obtaining the speed limit road sign. Alternatively, the legal speed information may be added to the map information of the car navigation device, and the legal speed information may be obtained based on the current position information of the vehicle 31 and the legal speed information included in the map information.

The server 40 is implemented by a computer, such as a personal computer, installed at a user's place of business. The server 40 may be realized by installing database software and an application program using the database in this computer. The application program is realized by adding a function to access the database 50, a function to specify search conditions, etc. to a conventional personal computer viewer for viewing image data and driving data recorded by the drive recorder 30, for example. do it. It is even better if the application program has a function of searching the data extracted from the database 50 for necessary data with additional search conditions.

The server 40 of the first embodiment may be composed of a database server having a database management function and a client having other functions. At this time, the database server and the client should be connected by a wired LAN or a wireless LAN. Terminals that are not connected to this LAN should be prevented from accessing the database server. As a result, it is possible to prevent the data stored in the database from leaking out of the office.

The server 40 according to the first embodiment collects image data and travel data from the drive recorder 30 mounted on the vehicle 31, but instead of the drive recorder 30 or in addition to the drive recorder 30, the server 40 is a fixed point camera. It is preferable to have a function of collecting captured image data. As a fixed point camera, for example, a surveillance camera installed to check the normality of the operation status of equipment in a factory, a surveillance camera installed in the premises where work vehicles move, and installed on the road where an unspecified number of people pass. security cameras installed in the building, and security cameras installed in the entrances and hallways of buildings. Data acquired by such a fixed-point camera does not include data corresponding to traveling data. For example, image data and date/time information may be transmitted from these cameras to the server 40 . Further, instead of the in-vehicle device identification information, device identification information for identifying the camera may be transmitted from the fixed point camera to the server 40 . When collecting data from a fixed point camera, it is preferable to use a wireless LAN as a wireless transmission path. If the wireless LAN access point cannot be detected, it is considered that some abnormality has occurred in the wireless LAN system. In addition, data may be transferred to the server 40 via a wired transmission path without via a wireless transmission path.

In the first embodiment, when wireless communication is possible, the drive recorder 30 constantly transmits image data, travel data, etc. to the server 40. However, the server 40 requests the drive recorder 30 to transmit specific data. and the drive recorder 30 transmits to the server 40 the image data and driving data requested by the received command. For example, the server 40 transmits a command "Send the image data acquired during the month, day, hour, minute, and minute." The drive recorder 30 reads the image data corresponding to the content of the request from the SD card and transmits it to the server 40 . In general, it is difficult to read and write to an SD card at the same time. Therefore, when reading image data, writing should be temporarily stopped. If the amount of data to be read is small, writing and reading may be executed simultaneously. If the amount of data to be read is less than a predetermined amount, it is preferable to read the necessary data without interrupting writing.

The image analysis unit 43 preferably has a function of analyzing the image inside the vehicle, identifying the driver by face authentication, and storing the driver identification information in the database 50 . The face authentication of the driver may be performed, for example, every time it is detected by image analysis that the driver is seated in the driver's seat after it is determined by image analysis that the driver's seat has become vacant.

In the first embodiment, after image data is received, image analysis is performed before it is stored in a database. , the server 40 preferably has a function of analyzing an image being reproduced and determining whether or not a near-miss incident has occurred. It is preferable that the server 40 has a function of stopping the reproduction at the moment when the occurrence of a near-miss incident is detected and notifying the viewer of the image of the occurrence of the near-miss incident.

The image analysis unit 43 preferably has a function of analyzing image data from a monitoring camera installed to confirm the normality of the operating conditions of the devices in the factory. If the equipment in the factory has a function to notify the occurrence of an abnormality by a method such as blinking an alarm lamp when an abnormality occurs, the blinking of the alarm lamp is detected by image analysis, and it is determined whether or not there was a notification of the occurrence of an abnormality. good. It is preferable to store information on the presence or absence of an abnormality in the database 50 as an analysis result.

The current position analysis unit 44 may group the current position of the vehicle 31 based on the distance from each of the plurality of intersections. For example, it is preferable to classify into a group with a distance of 100 m or less from the intersection A, a group with a distance of 100 m or less from the intersection B, or the like. By grouping in this way, it is possible to easily extract image data and travel data acquired near the intersection using the name of the intersection as a search key.

In addition, as a plurality of groups for classifying the current position, it is preferable to adopt the address of the current position, for example, the name of the municipality (up to the town name of the residential address). By grouping in this way, it is possible to easily extract image data and travel data acquired within the address using the address as a search key.

In the first embodiment, data is transmitted from the drive recorder 30 to the server 40 via the wireless transmission line 32. Data that could not be transmitted during operation is transmitted from the SD card of the drive recorder 30 after the vehicle has finished running. It is preferable to transfer the data to the server 40 . When data is transmitted to the server 40 via the wireless transmission line after the vehicle has finished running, it is desirable to keep the engine of the vehicle running until the data transmission is completed. When data is transferred to the server 40 via an SD card, the engine may be stopped after the vehicle has finished running. By using the data transfer via the SD card together, data loss is less likely to occur in the image data and driving data for each driver. It becomes difficult for unfairness to occur in the evaluation of each person. For example, it is possible to incorporate image data and driving data during the period when the vehicle is driving in a remote area or in the mountains where the radio wave of the mobile communication network does not reach, in the evaluation of the driver.

As one attribute of the database 50, data acquisition method identification information for identifying the method by which the data was acquired may be included. Data acquisition method identification information may be used to identify any one of wireless LAN, mobile communication network, and SD card. The user can search the database using the data acquisition method identification information as a search key.

The image data and travel data on the SD card may include a transmitted flag for identifying whether or not they have been transmitted via the wireless transmission path. When image data and travel data are read from the SD card to the server 40, the image data and travel data for which the sent flag is not set are read, and the image data and travel data for which the sent flag is set are transferred to the server 40. It is preferable that the server 40 has a function of not reading. If the sent flag is not recorded on the SD card, when reading data from the SD card, it will be recorded on the SD card based on the media identification information, vehicle equipment identification information, image acquisition time, image frame counter, etc. The server 40 preferably has a function of determining whether or not the image data stored in the database is already stored in the database, and reading image data or the like that is not stored in the database.

An event data recorder and a drive recorder 30 are mounted as in-vehicle devices in the same vehicle 31, and a server to which data of the event data recorder is transmitted and a server 40 to which data of the drive recorder 30 are transmitted are installed separately. Build a system. Here, the event data recorder mainly means an in-vehicle device for recording information of the vehicle 31 before and after the collision accident, and does not record image data. The drive recorder 30 is an in-vehicle device that records images of the surroundings of the vehicle 31 and data related to driving. Part of the data regarding the running state of the vehicle is redundantly recorded by the event data recorder and the drive recorder 30 .

The server for storing the data of the event data recorder and the server 40 according to the first embodiment for storing the data of the drive recorder 30 publish the database through a predetermined application programming interface, and the application program is installed in one personal computer. , it is preferable to have a function to combine and handle the data of the event data recorder of one vehicle 31 and the data of the drive recorder 30 . In order to combine the data of the event data recorder of one vehicle 31 and the data of the drive recorder 30, the vehicle equipment identification information of the event data recorder mounted on the same vehicle 31 and the vehicle equipment identification of the drive recorder 30 are used. Information should be associated in advance. This association information may be stored in a personal computer that accesses the two event data recorder servers and the drive recorder 30 server 40, for example. If the automobile registration number is associated with the vehicle equipment identification information, two pieces of vehicle equipment identification information can be associated based on the vehicle registration number.

The advantage/disadvantage determination unit 48 preferably has a function of transmitting information that is advantageous to the driver to the blockchain and not transmitting information that is disadvantageous to the driver when analyzing the cause of the accident.

In the first embodiment, the server 40 has the function of transmitting image data and travel data to the blockchain, but the drive recorder 30 may have the function of transmitting image data and travel data to the blockchain. In particular, the drive recorder 30 preferably has a function of transmitting information that is advantageous to the driver to the blockchain and not transmitting information that is disadvantageous to the driver. By transmitting to the blockchain in real time while driving, it becomes easier to prove that there was no tampering, and it is possible to prevent disclosure of data that is disadvantageous to you.

Predetermined data may be extracted from the data acquired by the server 40 or the drive recorder 30 and transmitted to a public database other than the blockchain.

The database management unit 42 displays, on the screen of the input/output device 60, a moving image obtained from the image data, a period from the start point to the end point of the moving image, and a timeline indicating the point in time during the current reproduction. It is preferable to provide a function for recognizably displaying on a timeline the period determined to be information advantageous to the user and the period determined to be disadvantageous information. For example, it is preferable to provide a function of displaying in red a period determined to be information unfavorable to the driver, and displaying in blue a period determined to be advantageous information.

The advantage/disadvantage determination unit 48 preferably has a function of extracting only information that is advantageous to the driver and displaying or printing it on the screen. It is even better if the information that is disadvantageous to the driver is encrypted so that a third party cannot easily access it.

It is even better if the advantage/disadvantage determination unit 48 has a function of extracting only information that is advantageous to the driver and automatically preparing a statement of opinion to be submitted to the lawsuit when a lawsuit regarding an accident occurs. For example, "When we entered the intersection, the traffic light on our side was green.", "We were driving at the legal speed limit when the accident occurred.", "We stopped before the intersection." It is preferable to have a function to automatically generate sentences such as "." and create a written opinion.

In the first embodiment, a relational database is adopted as the database 50, but a document-oriented database or a graph database may be adopted besides the relational database or in addition to the relational database.

When using a document-oriented database, each column of the GPS log should be captured in JSON format, and the original data should also be captured in JSON format. The original data should also be searchable. For example, it is possible to easily perform a process of extracting only traveling data of 80 km/h or less.

When using a graph type database, it is preferable to store relationships among a large number of vehicles, drivers, places visited, places where unsafe driving is performed, etc. in a graph structure. This makes it possible to easily display drivers who have similar driving styles, vehicles and drivers related to dangerous places, and the like. It would be even better if it had a function to display the graph structure as a figure. This function can be effectively used to improve the efficiency of patrol work.

It is preferable to store the relationship between the biological information of the driver and the abnormality information (location, time, content of abnormality in behavior of the vehicle, etc.) in a graph database. By doing so, it becomes easier to visualize the relationship between the driver's biological condition and driving. The biological state of the driver may include, for example, information such as looking aside while looking at the head, dozing off based on how open the eyes are, driving posture, heart rate, and the like. The abnormality information may include, for example, information regarding the presence or absence of occurrence of lane departure, abnormal inter-vehicle distance, sudden braking, sudden start, and the like. Furthermore, it is preferable to store the result of the roll call in the database as driver information.

Instead of face-to-face roll call, IT roll call is permitted, which uses equipment approved by the Minister of Land, Infrastructure, Transport and Tourism to perform roll call remotely. For example, an operation manager who is on standby at an office may provide the server 40 and the drive recorder 30 with a function of making an IT roll call using wireless communication between the server 40 installed at the office and the drive recorder 30. Be prepared. The server 40 preferably has a function of inputting the result of the IT roll call to the operation manager and a function of storing the input roll call result in the database 50 as driver information. Further, the server 40 preferably has a function of performing image analysis based on the image data of the driver transmitted from the drive recorder 30 to the server 40 to determine the health condition of the driver and whether or not the driver is drunk. The server 40 preferably has a function of storing the determination result in the database 50 as information about the driver.

It is preferable that the server 40 has a function of displaying the time period and place where there is a shortage of personnel by using a graph database. Furthermore, based on this information, it is preferable to have a function of issuing a job advertisement.

The server 40 according to the first embodiment receives image data from a fixed camera that captures an image of a specific location, associates the received image data with a fixed camera identifier that identifies the fixed camera and information on the date and time when the image was taken, and stores the data in the database 50. It is preferable to further have a function of storing in the .

The image data acquired by the fixed camera and the image data acquired by the drive recorder 30 mounted on the vehicle can be collectively managed in the database 50 . For example, it is preferable to use a premises where trucks and forklifts run as a place to be imaged by the fixed camera. In some cases, it is possible to supplement an image of a blind spot of a stationary camera where a large truck is parked with image data captured by a drive recorder 30 of a truck, forklift, or the like. The drive recorders 30 that are likely to capture an image of a blind spot for a fixed camera can be narrowed down based on date/time information, position information, and the like.

[Second embodiment]
Next, referring to FIG. 2, the vehicle-mounted equipment according to the second embodiment will be described by taking a drive recorder as an example.
FIG. 2 is a block diagram showing functions of the drive recorder 30 according to the second embodiment. The drive recorder 30 includes a processing unit 80 , a GPS receiver 81 , a camera 82 , an SD card reader/writer 83 , an acceleration sensor 84 , an RFID module 85 , a speaker 86 , a display 87 , operation buttons 88 and a WiFi communication module 89 .

The speaker 86 and display 87 function as output means for informing the user of various information. The speaker 86 issues warnings and various information by sound and voice under the control of the processing unit 80 . The display 87 displays various information as images under the control of the processing unit 80 . The operation button 88 functions as input means for the user to give various commands to the drive recorder 30 .

The GPS receiver 81 detects positional information of the vehicle at the current time based on instructions from the processing unit 80 . The positional information includes information such as the time obtained based on the signals from the GPS satellites, the speed of the vehicle, longitude, latitude and altitude. The processing unit 80 performs a process of recording the history of the position information.

The camera 82 images the front of the vehicle as a moving image. A moving image captured by the camera 82 is taken into the processing unit 80 as image data.

The SD card reader/writer 83 reads data from the SD card or records data on the SD card under the control of the processing unit 80 .

As the acceleration sensor 84, a 3-axis type sensor that detects acceleration and tilt in each of 3 axes (x-axis, y-axis, z-axis) is used. The acceleration sensor 84 always outputs the detected value to the processing section 80 . The processing unit 80 acquires triaxial acceleration information every 10 ms, for example.

The RFID module 85 receives a signal from the RFID tag 75 according to a command from the processing section 80 . The reception result is taken into the processing unit 80 , and the processing unit 80 reads the ID information included in the signal from the RFID tag 75 .

The WiFi communication module 89 performs data communication with the server 40 ( FIG. 1 ) via the access point 35 according to a command from the processing unit 80 .

The processing unit 80 acquires various travel data from the ECU 33 of the vehicle. The travel data includes speed information and information representing operations performed on the vehicle (for example, brake and accelerator operation information, steering information, etc.).

The processing unit 80 transmits position information acquired from the GPS receiver 81, acceleration information acquired from the acceleration sensor 84, image data acquired from the camera 82, and travel data acquired from the ECU 33 to the server 40 ( Figure 1). These data are recorded in the SD card attached to the SD card reader/writer 83 during the period in which wireless communication cannot be performed. When wireless communication becomes possible, at least part of the image data and driving data recorded on the SD card is transmitted to the server 40 (FIG. 1) via the WiFi communication module 89. FIG. The data to be transmitted when wireless communication becomes possible is determined based on the data processing speed of the drive recorder 30, the communication speed of the wireless transmission line, and the like. For example, if there is sufficient margin in the data processing speed and communication speed, all image data and travel data are transmitted. If the data processing speed or communication speed does not have enough margin, only part of the image data and travel data is transmitted. The type of data to be transmitted is set in the processing unit 80 in advance. The period during which wireless communication is not possible includes the period during which the vehicle is traveling outside the wireless communication available area, the period during which wireless communication is disabled due to a failure in the wireless communication system, and the like.

The processing unit 80 further stores the ID information obtained based on the signal obtained from the RFID module 85 in the SD card.

Next, the excellent effects of the second embodiment will be described.
In the method of transferring the driving data and image data from the drive recorder 30 to the server 40 via the SD card, it is necessary to carry the SD card. In the drive recorder 30 according to the second embodiment, the driving data and image data transmitted via the wireless transmission line can be handed over to the server 40 without carrying the SD card. Some of the traveling data and image data obtained while traveling in an area where wireless communication is not possible can be transferred to an external device via a wireless transmission line. This saves the trouble of handing over travel data, image data, and the like.

Next, various modifications of the second embodiment will be described. Note that functions of the server 40 related to the functions of the drive recorder 30 will also be described in the angular variation.

<Data to be sent after wireless communication becomes possible>
In the second embodiment, when wireless communication becomes possible, at least part of the image data and travel data recorded in the SD card is transmitted to the server 40 (FIG. 1) via the WiFi communication module 89. In this modification, when wireless communication becomes possible, the driving data recorded on the SD card during the period when wireless communication was not possible is transmitted via the wireless transmission path, and the image data recorded on the SD card is transmitted. Don't send.

Normally, the amount of image data is much larger than the amount of travel data. By not transmitting image data after wireless communication has become possible, even if there is not enough margin in the transmission speed, wireless communication was not possible without stopping the transmission of image data and driving data acquired at the present time. Running data for the period can be transmitted.

For example, if wireless communication is unavailable for about one hour, about 8 GB of image data is accumulated during this period. SD cards are not good at writing and reading data at the same time. It is difficult to read the image data written during the period when wireless communication was not possible while writing the image data currently being collected to the SD card. Furthermore, it is difficult to transmit about 8 GB of image data along with the image data currently being collected through a wireless transmission line. In such a case, by not transmitting the image data collected during the period when wireless communication was not possible, but transmitting the driving data, it is possible to prevent the lack of the driving data. The image data that could not be transmitted should be read by the server 40 (FIG. 1) via the SD card.

<Items to be included in driving data>
The travel data to be transmitted to the server 40 should preferably include items specified by technical standards for digital tachographs (digital operation recorders). For example, time information, instantaneous speed information, mileage information, identification information for specifying the vehicle, etc. may be included. As a result, the drive recorder 30 can be used as a substitute for the digital tachograph. Also, it is preferable to transmit the time during which the engine is turned off to the server 40 . Then, the operation manager who is the user of the server 40 can easily know the rest time of the driver.

A server 40 (FIG. 1) that collects such information from the drive recorder 30 has a function of displaying daily, weekly, and monthly travel distances for each driver and each vehicle. It also has a function that allows a user who uses the server 40 (FIG. 1) to specify a period for totaling traveled distances.

<Function to identify the driver>
The drive recorder 30 has a function of reading the driver's license information, recording information identifying the driver who will drive from now on in association with image data and driving data, and a function of transmitting to the server 40 . Alternatively, the drive recorder 30 has a function of capturing an image of the interior of the vehicle, and has a function of identifying the driver by performing face recognition, for example, by analyzing the image of the driver reflected in the image of the interior of the vehicle. and even better.

<Applications other than automotive applications>
Although the drive recorder 30 mounted on the vehicle has been described in the second embodiment, it is preferable to provide other electronic devices with the same function as the drive recorder 30 and other vehicle-mounted devices. Such an electronic device collects image data from, for example, a surveillance camera or the like whose location is fixed, and transmits the data to the server 40 (FIG. 1) via a wireless transmission line. In this case, data corresponding to travel data is not transmitted, but image data, device identification information, date and time information, and the like are transmitted. This electronic device has a function of recording image data and the like in a storage device such as an SD card when data cannot be transmitted due to a failure in the wireless transmission line. It has a function of transmitting at least part of data such as recorded image data via a wireless transmission path when wireless communication becomes possible.

<Function to transmit connection status and operation status>
The drive recorder 30 has a function of transmitting, via the wireless transmission path 32, information regarding the connection status and the operating status via the wireless transmission path 32. FIG.

A user of the server 40 can know the connection state with the drive recorder 30 via the wireless transmission path 32 or the operating state of the drive recorder 30 . For example, when the drive recorder 30 and the server 40 are not connected, the drive recorder 30 is not operating because the engine of the vehicle is turned off. It includes a state in which communication is not possible, a state in which communication is not possible due to a failure of the drive recorder 30, and the like. When communication becomes possible, the drive recorder 30 has a function of transmitting engine on/off time information, time when radio waves become weak and communication becomes impossible, time when communication is restored, and the like. Further, it has a function of transmitting information indicating whether or not image data and travel data are being recorded normally as the operating state of the drive recorder 30 .

The drive recorder 30 has a function of recording a history of the connection state and operation state and transmitting information representing the current connection state and operation state to the server 40 in real time. The server 40 has a function of notifying the user by outputting to the input/output device 60 information representing the connection state and operation state received in real time. A user using the server 40 can know the operating state of the drive recorder 30 in real time. In particular, the server 40 has a function of immediately notifying the user when the operating state of the drive recorder 30 is abnormal. A user who notices the abnormality can take some action to avoid trouble. For example, if errors have frequently occurred in the imaging device in the past, it is possible to take measures such as replacing the imaging device. In addition, when writing errors to the SD card frequently occur in the past, it is possible to take measures such as replacing the SD card.

<Overwrite counter value transmission function>
The drive recorder 30 stores the function of sequentially overwriting and recording image data on the SD card and the number of times the SD card has been overwritten in an overwrite counter secured in the storage area of the SD card. It has a function of transmitting via the wireless transmission line 32 .

In general, when an SD card is repeatedly overwritten, the SD card deteriorates and write errors tend to occur, so an upper limit is set for the number of overwrites that can be performed. The server 40 that has received the value of the overwrite counter can predict when the SD card will be replaced by checking the value of the overwrite counter. The server 40 has a function of outputting the number of remaining overwrites to the input/output device 60 and notifying the user. This output should be performed when the number of remaining overwritable times falls below a certain reference value.

The drive recorder 30 further has a function of inheriting the value of the overwrite counter before and after formatting the SD card. For example, the drive recorder 30 reads the value of the overwrite counter before formatting and writes the value before formatting to the overwrite counter after formatting. By providing a function to take over the value of the overwrite counter, the user can save the trouble of performing an operation to take over the value of the overwrite counter when formatting the SD card.

<Event notification function>
The drive recorder 30 has a function of detecting an event that has occurred in the vehicle 31, and a function of notifying the server 40 of the occurrence of the event via the wireless transmission line 32 when detecting the occurrence of the event.

A user of the server 40 can know that some event has occurred in the vehicle 31 . The drive recorder 30 should preferably notify the occurrence of the event in real time. Thereby, the user of the server 40 can notice the occurrence of the event at an early stage.

<Character recognition function>
Next, the character recognition function of the drive recorder 30 will be explained.
The drive recorder 30 has a function of analyzing the image data acquired by the camera 82 , recognizing characters contained in the image data, converting the character information into voice, and outputting the voice from the speaker 86 .

This function makes it possible for the driver to become aware of character signboards and the like that he did not notice while driving. For example, when there is information about a destination, for example, a guide signboard that says, "Turn right after XX, 200 m", the driver can notice that he should turn right even if he misses the guide signboard.

Further, when the drive recorder 30 finds character information of a facility such as a store, a hospital, or a public facility by image analysis, it accesses the Internet, searches for the address of the facility, and interlocks with the car navigation system to locate the facility. It has a function to set as a destination.

For example, when driving from Okazaki on National Route 1 toward Toyohashi, you will notice a sign that says "Baby Brush Center". The drive recorder 30 recognizes the characters on this signboard, automatically searches through the Internet, and reads out the search results using the text-to-speech (TTS) function. At this time, from the search results, it recognizes the closest thing to the current location, the direction indication and the distance indication on the signboard, extracts the things within the range and direction from the current location, and reads out only the extracted search results. The drive recorder 30 has the function.

For example, there are "Baby Brush Centers" in Tokyo, Kawaguchi, Nagoya, and Toyokawa. When the drive recorder 30 recognizes the signboard of "Baby Brush Center" while traveling in the direction of Toyohashi in Miai, the contents of the web page of the Baby Brush Center in Toyokawa, which is the closest and in the direction of travel. read aloud. The drive recorder 30 has a function of retrieving a telephone number when a number string corresponding to the telephone number on the signboard is recognized.

At the end of the voice output, the drive recorder 30 outputs a voice asking the driver whether or not to set the recognized facility as the destination, for example, "Would you like to set this place as the destination?" It has a function to wait for a voice response from the driver. When the driver gives an affirmative answer to set the destination, the drive recorder 30 interlocks with the car navigation system and has a function of causing the car navigation system to set the facility as the destination. . The car navigation system interlocked with the drive recorder 30 starts route guidance to the facility.

Further, the drive recorder 30 analyzes the image in which the driver is reflected, recognizes the line of sight of the driver, and gives priority to the commentary on the signboard when it is recognized that the driver is gazing at the signboard ahead of the line of sight. It has a function to perform effectively.

In particular, when automatic driving is realized, the driver will be released from the driving operation and will be idle. For example, research is being conducted on games that replace the scenery from the vehicle with a virtual world, move in the virtual world according to the movement of the vehicle, and make monsters appear in the virtual world when the traffic light turns red. . In such a game, it is preferable to use an automatic read-aloud function by voice.

The drive recorder 30 has a function of canceling this function. For example, when driving on a road with a large number of signboards installed, canceling this function can prevent frequent unnecessary voice outputs from interfering with driving.

Character signs to inform drivers that automatic speed control devices and mobile orvis are installed, for example, recognize the character "automatic speed control" among character signs such as "route with automatic speed control device installed" The drive recorder 30 further has a function of issuing an alarm or a function of issuing an audible warning. Based on the rule of the Supreme Court decision in the Kyoto Gakufuren Incident, ``No one has the freedom to not have his or her face photographed without permission. , is installed in front of the control machine. Small, portable mobile orvis also take pictures automatically, so similar text signs are installed based on this norm. Therefore, by issuing an alarm or warning to the driver based on the existence of this character sign, it is possible to motivate the driver to obey the traffic rules before the location where the automatic speed control device is installed.

If the drive recorder 30 has a POI file of the installation location of the automatic speed control device, and the installation location of the automatic speed control device is within a predetermined distance (for example, 2 km) of the current route, the POI file It is equipped with a function to issue only an alarm or warning based on the character sign and not to issue an alarm or warning based on the character sign. For fixedly installed speed control devices, issuing an alarm or warning based on the POI file is sufficient. However, a POI file cannot be created in advance for a temporary installation such as a mobile orbis. Therefore, for mobile orvis, the drive recorder 30 has the function of issuing an alarm or warning by recognizing the character sign.

Character signs to notify the installation of the automatic speed control device are installed in two places up to the point where the automatic speed control device is installed. The drive recorder 30 has a function of making the alarm or warning stronger when the character sign is recognized the second time than when the character sign is recognized the first time. For example, when the character sign is recognized for the second time, the drive recorder 30 issues an alarm or warning that is more noticeable to the driver. The drive recorder 30 further has a function of not issuing an alarm or a warning when the vehicle deviates from the installation location of the automatic speed control device due to a right or left turn. Automatic speed control devices detect speed by directing radar or laser at the vehicle. The drive recorder 30 has a function of detecting (catching) this radar or laser signal. The drive recorder 30 has a function of issuing a stronger alarm or warning when these signals are detected. Furthermore, it has a function to notify the driver of passing through a point where these signals are detected.

Furthermore, in the zone 30 area, the drive recorder 30 has a function of issuing a stronger alarm or warning when issuing an alarm or warning due to recognition of a sign.

<Function of drive recorder in cargo handling vehicle>
Next, an example in which the drive recorder 30 is mounted on a vehicle or device such as a forklift, hoist, or crane that performs cargo handling work will be described. This drive recorder 30 has a function of reading a mark such as a bar code attached to a package. Furthermore, in addition to marks and the like, it has a function of recognizing characters given to packages. A package can be specified by reading a mark or characters (hereinafter referred to as package identification information) attached to the package. This information can be used for cargo handling work.

Furthermore, a celestial camera (360-degree camera) and a plurality of cameras for imaging the surroundings are mounted on cargo handling vehicles and cargo handling equipment. The drive recorder 30 has a function of reading the baggage identification information given to the surrounding baggage by image recognition from the images captured by these cameras, and identifying the location where the baggage to be transported is stored. The drive recorder 30 has a function of displaying on the display 87 the location (direction and position relative to the own vehicle) where the cargo to be transported is stored.

For example, assume that a cardboard box of Mikkabi oranges is placed in front of the first forklift in a warehouse, a cardboard box of Unshu oranges is placed behind it, a cardboard box of Aoshima oranges is placed on the right, and a cardboard box of Ponkan is placed on the left. Each cardboard box is provided with a barcode for identifying the contents. Through wireless communication, the on-vehicle device of the first forklift receives information that it is necessary to load 15 cardboard boxes of Qingdao mandarin oranges, which are currently being shipped from the warehouse, onto the No. 5 truck of Company A, which is located alongside the No. 1 loading area. sent. The drive recorder 30 of the first forklift is connected with communication functions such as LPWA and WiFi, four cameras on the front, back, left and right, and a display. The display shows information such as "Product name: Qingdao mandarin orange", "Quantity: 15", "Location: First loading area", and "Truck: No. 5 truck of A company". The drive recorder 30 performs image recognition to determine whether any of the images captured by the four cameras has a barcode indicating "Qingdao mandarin orange". In this example, it recognizes that there is a barcode of "Aoshima oranges" in the image of the camera capturing the right side, and displays the information "The object to be transported is Aoshima oranges on the right side." The same content is notified by voice. The drive recorder 30 has a function of displaying, for example, the direction of the object to be loaded as an arrow on the display 87 . Furthermore, the drive recorder 30 has a function of conspicuously displaying the range in which the object to be loaded is captured among the images of the four cameras. For example, the real-time image of the drive recorder 30 recognizes the area where the object to be transported is shown (identifies the cardboard box with the barcode of Qingdao mandarin orange and recognizes the range), and the translucent red with hatching.

I explained an example of a kind of thing like a mandarin orange (any cardboard box of that kind is fine), but the object to be transported is a specific thing (such as a mail order package addressed to Mr. A). This function is particularly useful in the case of , since the appearance of the box does not allow one to recognize that particular package. For example, the above function is particularly useful when packages addressed to companies A, B, C, and D have the same appearance but different contents.

The drive recorder 30 has a function of counting the number of cardboard boxes transported and reporting the number of remaining cardboard boxes to be transported. It is equipped with a function to issue a notification to that effect when it is likely to carry too much. Furthermore, it is equipped with a function for navigating the traveling route within the premises from the location of the cargo to be transported to the transport destination. When the object to be transported is placed on the fork of the forklift, loaded on the truck, unloaded from the fork, and unloaded from the truck, the transportation status of the cargo is recorded in the office server, cloud database and blockchain. The drive recorder 30 has the function of

Instead of attaching package identification information to packages, it may be assigned to pallets and racks. As the parcel identification information, for example, a two-dimensional code or other various codes may be used in addition to the bar code.

<RFID tag reading function>
Next, the function of the drive recorder 30 to read the information of the RFID tag will be described. The drive recorder 30 has a function of communicating with the RFID tag, reading information stored in the RFID tag, and storing the reading result in a storage device.

It is thought that a system like Amazon Go will appear in the future that does not require a cash register when shopping, and the payment is automatically completed just by picking up the product from the shelf and leaving the store. For example, by 2025, it is planned that RFID tags will be attached to all products at convenience stores (attached at the time of product manufacture). The drive recorder 30 reads the information of the RFID tag attached to the product purchased by the passenger of the vehicle and brought into the vehicle. By storing the read information, the drive recorder 30 can create, for example, a list of purchased products.

Next, an example in which a camera is installed in a store will be described as a modified example of the RFID tag reading function.
The store equipment according to this modification has a function of installing a camera at the entrance of the store and photographing the purchaser when the purchaser passes through the RFID reading gate. Furthermore, this store equipment has a function of determining the age and sex of the purchaser from the image of the purchaser, and recording information on the age and sex of the purchaser in association with the sales record of the product.

At convenience stores, payment confirmation buttons on the register are arranged by age and gender, and the store clerk judges the purchaser's age and gender based on the purchaser's appearance (appearance) and presses one of the payment confirmation buttons. , enter the purchaser's age and gender information. By automatically determining the purchaser's age and sex from the purchaser's image using the function of the store equipment according to this modified example, it is possible to save the work of the store clerk. In addition, it is possible to more objectively determine the age and gender by eliminating subjectivity of the store clerk.

Furthermore, the store equipment according to this modified example automatically determines the type of clothing (work clothes, school uniforms, suits, etc.) and the group type (single, couple, family, with children, etc.) in addition to the purchaser's age and gender. It has a function of recording in association with the sales record of the product. Furthermore, the store equipment according to this modified example has a function of determining the presence or absence of companions based on the people who entered and exited the gate in close time proximity, and determining the group type based on this determination result.

When a plurality of purchasers carrying commodities pass through the RFID reading gate at the same time, it becomes impossible to determine which purchaser should be charged for which commodities. Therefore, in principle, only one person can pass through the RFID reading gate at a time. Therefore, as described above, it is possible to determine the presence or absence of companions from people who entered and exited the gate in close time proximity.

The store equipment according to this modified example further has a function of counting people who pass through the RFID reading gate during the period from the reading of the RFID tag to the reading of the next RFID tag as one group. Also, if you set an upper limit for the time interval counted as one group, and multiple people pass through the gate in a time interval that exceeds this upper limit, these multiple people will not be counted as the same group. It has

The store equipment according to this modification has a function of capturing an image from a camera installed in the parking lot of the store. The store equipment has a function of determining that people who have gotten into the same vehicle belong to one group from the images taken by the cameras installed in the parking lot. With this function, it is possible to improve the accuracy of determining a plurality of people as one group.

Furthermore, the store equipment according to this modified example has a function of transmitting the recognition result of the purchaser and the accompanying person to a server on the cloud or storing it in a local server installed in the store.

The server 40 has a function of allowing the user to input conditions for outputting the message to the drive recorder 30 in addition to inputting the message. As this condition, a condition regarding the position of the vehicle, for example, a condition that the current position of the vehicle is within a predetermined range can be applied. For example, if a condition is set that the current position of the vehicle is in the parking lot of the office, it is possible to notify the driver of the message when the vehicle returns to the parking lot of the office. For example, the driver is instructed to output a message such as "Today, there will be a barbecue party from 18:00. Please join us if you wish." from the drive recorder 30 of the vehicle returning to the parking lot. be able to.

The server 40 further has a function of setting a time condition for outputting the message as a condition for outputting the message. For example, when the current time satisfies the set time condition, the server 40 sends a command to the drive recorder 30 to output the message. In addition, the server 40 has a function of transmitting message items and time conditions to the in-vehicle equipment. The drive recorder 30 has a function of determining whether or not a set time condition is satisfied, and outputting a message when the time condition is satisfied. For example, if the start time of the barbecue party is 6:00 p.m., setting the time condition to be before 6:00 p.m. However, if the start time of the barbecue party has passed, it is possible to prevent the notification of the barbecue party from being sent.

In addition, the operation manager can operate the server 40 to notify the driver to bring the SD card to the operation management department. For example, if image data or travel data that has not been transmitted to the server 40 via the wireless transmission line 32 remains in the drive recorder 30, the driver of the vehicle 31 equipped with the drive recorder 30 that has unsent data remains. can be notified to bring the SD card to the operation management department.

The server 40 and the drive recorder 30 provide a function that allows the operation manager who operates the server 40 and the driver of the vehicle equipped with the drive recorder 30 to interact via the drive recorder 30 and the server 40. I have more. By using this dialogue function, the recipient of the message can immediately respond to the message sent from one of the operation manager and the driver to the other with high immediacy.

It transmits via the wireless transmission line 32 . As shown in FIG. 12B , when the user performs an operation to update the firmware, the server 40 transmits a firmware update command to the drive recorder 30 via the wireless transmission path 32 .

The operation manager who is the user can change the setting information of the drive recorder 30 without going to the vehicle in which the drive recorder 30 is mounted. Also, the system administrator who is the user can update the firmware of the drive recorder 30 without going to the vehicle in which the drive recorder 30 is mounted.

When the user designates a specific drive recorder 30 and performs an operation to change the setting information or update the firmware, the server 40 performs a function to change the setting information or update the firmware of the specified drive recorder 30. have Furthermore, if the user performs an operation to change the setting information or update the firmware without specifying a specific drive recorder 30, the server 40 changes the setting information or updates the firmware of all drive recorders 30 to be managed. It has a function to update. By using this function, it is possible to simplify the operation of changing or updating the setting information or updating the firmware compared to performing the operation of changing the setting information or updating the firmware for each of the plurality of drive recorders 30 to be managed.

Further, the server 40 has a function of classifying a plurality of drive recorders 30 to be managed into a plurality of groups and changing setting information or updating firmware for each group. The server 40 has a function of classifying the drive recorders 30 according to the safe driving level and skill level of the driver of the vehicle 31 in which the drive recorders 30 are mounted, by the operation of the operation manager who is the user. For example, drivers are classified into three groups of "high", "normal", and "low" safe driving levels, and the drive recorders 30 are divided into three groups according to the correspondence between the drivers and the drive recorders 30. Categorize into groups. For example, in a vehicle driven by a driver with a high degree of safe driving, it is difficult for the event triggered by the acceleration to occur because it is difficult for a situation in which acceleration such as sudden start or sudden braking occurs to occur. In order to detect a certain degree of event even in the vehicle of a driver with a high degree of safe driving, the server 40 sets the acceleration threshold for determining that an event has occurred to be lower than the thresholds for other groups. . Conversely, for vehicles of drivers with a low degree of safe driving, the server 40 sets the resolution of image data to be recorded higher than that of other groups to facilitate cause analysis when accidents or near-miss incidents occur. . Also, when the user performs an operation to designate a driver who has a strong tendency to perform dangerous actions or actions while driving, the server 40 classifies the driver into a specific group, and selects a drive corresponding to the driver. The recorder 30 is set to collect detailed images of the interior of the vehicle. Here, as an example of "detailedly", the server 40 executes setting of at least one of increasing the resolution and increasing the frame rate.

Further, the server 40 has a function of grouping the drive recorders 30 in accordance with the division within the company (department) to which the driver belongs. For example, the server 40 performs grouping for each department such as a design department, a sales department, and a planning department.

When the operation manager or system manager who is the user operates the server 40 and instructs to change the setting information of the drive recorder 30 or to update the firmware, the drive recorder 30 that is incapable of wireless communication , the server 40 has a function of making a reservation for changing setting information or making a reservation for firmware update. When the drive recorder 30 for which a reservation for setting information change or firmware update has been reserved becomes capable of wireless communication with the server 40, the server 40 automatically instructs the drive recorder 30 to change the setting information or update the firmware. have the ability to send

When the user performs an operation to format (initialize) the SD card on the screen shown in FIG. 12B, the server 40 sends a command to format the SD card to the drive recorder 30 . For example, when the SD card needs to be reformatted due to updating the firmware of the drive recorder 30, the user can format the SD card of the drive recorder 30 using this function.

The server 40 has a function of determining whether or not the SD card needs to be formatted when the system administrator who is the user operates to update the firmware. When formatting is necessary, the server 40 has a function of notifying the system administrator that "image data and driving data will be deleted because the SD card needs to be formatted". Furthermore, the server 40 has a function of notifying the system administrator whether or not image data and travel data that have not been transmitted remain in the drive recorder 30 . After making this notification, the server 40 has a function of allowing the system administrator to select whether to update the firmware or cancel it. As a result, it is possible to prevent the occurrence of a situation in which image data and travel data are erased even though the system administrator wants to keep them.

Further, the server 40 has a function of instructing the drive recorder 30 to format the SD card after transmitting all the image data and travel data recorded on the SD card to the server 40 . Upon receiving this command, the drive recorder 30 has a function of automatically starting to format the SD card after transmitting all the image data and driving data recorded in the SD card to the server 40 .

When the system administrator who is the user performs an operation to update the firmware, the server 40 suspends the recording of the drive recorder 30 during the firmware update before sending the command to update the firmware to the drive recorder 30. It has a function to notify the system administrator. After making this notification, the server 40 has a function of allowing the system administrator to select whether to execute or cancel the firmware update. This allows system administrators to cancel the firmware update if they do not want to interrupt the recording.

<Management function of driving car>
Functions of the server 40 relating to the screen for managing drivers shown in FIG. 14A will be described. The database 50 includes driver identification information that identifies the driver of the vehicle 31, and has a function of setting data management conditions for the database 50 for each driver identified by the driver identification information.

With this function, it is possible to set optimal data management conditions for each driver and manage data. As data management conditions, for example, the storage capacity upper limit value, data storage period, attributes of image data, necessity of event recording, and the like are adopted.

Since the storage capacity of the database 50 is finite, when the amount of data accumulated in the database 50 reaches the upper limit of the storage capacity, past data must be deleted or discarded without storing new data. If the maximum capacity (upper limit of storage capacity) of the storage area corresponding to a specific driver is increased and the data storage period is set long, data relating to that driver is less likely to be deleted. For example, by making the maximum capacity of the storage area for the data about the driver to be managed intensively larger than the maximum capacity of the storage area for the data about the other drivers, the data about the driver to be managed intensively is less likely to be deleted. You can get the effect of becoming

By making the retention period of the data on the driver to be managed intensively longer than the retention period of the data on the other drivers, the data on the driver to be managed intensively can be stored for a longer period of time. For example, the driver can set the data retention period to one day or one year.

For example, resolution, frame rate, etc. are adopted as attributes of the image data. When the operation manager, who is the user, operates the server 40 to specify the driver and input the attributes of the image data, the server 40 sends the drive recorder 30 installed in the vehicle 31 in which the specified driver rides. It has a function of acquiring device identification information and transmitting a command to change to the input attribute to the drive recorder 30 corresponding to the vehicle-mounted device identification information. The drive recorder 30 that has received this command has the function of changing the attributes of the image data to be recorded and transmitted.

When the operation manager, who is the user, operates the server 40 to specify the driver and set whether or not to record the event, the server 40 stores the drive recorder 30 installed in the vehicle 31 in which the specified driver rides. It has a function of acquiring device identification information and transmitting a command to the drive recorder 30 corresponding to the in-vehicle device identification information to change the input set value of event recording necessity. The drive recorder 30 that has received this command has a function of enabling or disabling the event recording function according to the set value of whether or not event recording is necessary.

Instead of setting these settings for each driver, the server 40 has a function of classifying a plurality of drivers into a plurality of groups and changing these settings for each group. For example, the server 40 has a function of classifying drivers into groups such as "excellent", "normal", and "dangerous" according to their driving skills and driving attitudes through user operation. In this way, the data management condition setting operation by the operation manager can be simplified compared to the case where the data management conditions are set by designating each driver.

The server 40 also has a function of outputting the labor management information for each driver in the form of a list based on the database 50 . It also has a function to allow the operation manager, who is the user, to input the driver for whom the labor management information is to be output, the working period, and the like.
