Abstract

To suppress further power consumption in a system for controlling communication means by LPWA.SOLUTION: In a drive recorder 1, a camera 18 captures an image of a driver's seat and outputs a vide signal indicating this image. A controller 11 converts this video signal into video data, analyzes the video data to determine a danger of driving, generates determination result data indicating a determination result, and causes an LPWA communication device 13 to transmit the generated determination result data to a server 2. Since the determination result data is data indicating a comprehensive determination result obtained by analyzing the content of the video data and comparing motion and a position of each site of a driver with a predetermined pattern, a threshold value, etc., an information amount of the determination result data is smaller than an information amount of the video data. Therefore, power to be consumed when a drive recorder 1 transmits data to the server 2 is suppressed as compared with a case where the drive recorder 1 transmits the video data which is data before the video data has been processed.SELECTED DRAWING: Figure 4

JP-A-2018-59706

Communication by LPWA (Low Power Wide Area) is generally known to consume less power than 4G or 5G.

An object of the present invention is, for example, to further suppress power consumption in a system that controls communication means by LPWA, which generally consumes less power than communication by 4G or 5G. Further, not limited to this, the purpose is to provide a system superior to the conventional one.

The object of the invention of the present application is not limited to this, and there is an intention to acquire rights by divisional application, amendment, etc. even for a configuration for the purpose of obtaining an effect produced from a portion of the configuration disclosed in the present specification, drawings, etc. .. For example, the present specification discloses a problem in which the part described as "can be" is replaced with "is a problem" in the present specification. The issues are described as independent, and the intention is to acquire the rights to solve each issue independently by divisional application, amendment, etc. Even if the subject matter is implicitly grasped from the description in the specification, the applicant intends to make a part of the structure described in the specification amended or to be claimed in the divisional application. It also discloses a structure that solves problems that combine these independent problems, and has the intention to acquire rights.

(1) A system that controls communication means by LPWA (Low Power Wide Area).
A system having a power consumption suppressing means for controlling the communication means so as to suppress the power consumed may be used.

The power consumption is suppressed as compared with the case where the power consumption suppressing means is not provided.
As the LPWA, for example, it is preferable to use one that realizes long-distance data communication with low power consumption as compared with a communication method such as 4G or 5G. For LPWA, for example, a 920 MHz band or the like may be used. LPWA may be capable of long-distance transmission of several kilometers with low power consumption, for example. As the LPWA, for example, one having a low bit rate and a limitation on the amount of transmission per period may be used.

LPWA includes, for example, "ELTRES""LoRa""LoRaWAN""LTE-MTC""NB-IoT""NB-FiProtocol""RPMA""GreenOFDM""DASH7""RPMA""Wi-SUN""EnOcean" It is recommended to use at least one of "Long Range", "Weightless-P", "SIGFOX", "LTE Cat.0", "LTE Cat.M1", etc.
In particular, the system may be configured as a battery-powered device.
As a method of controlling the power consumption so as to be suppressed, for example, the methods illustrated in (2) to (22) described later may be used. In particular, the data transmitted in this way may be stored in the database by the system on the receiving side, but it is extremely good to store it in the blockchain.

(2) The power consumption suppressing means may be a system that causes the communication means to transmit a specific type of data in which the amount of data to be transmitted is smaller than that of other types of data.

Compared to systems that transmit other types of data, less data is transmitted.
As the content of the control for controlling the communication means so as to suppress the power consumption, the communication means is made to transmit a specific type of data in which the amount of data transmitted by the power consumption suppression means is smaller than that of other types of data. It is good to control.
For example, a taxi calling device equipped with an LPWA communication function, a taxi calling button, and a display will be installed in a facility such as a pub. The taxi will be equipped with an empty vehicle notification device equipped with GPS and LPWA communication functions and an empty vehicle button and display device that can be operated by the taxi driver. The taxi calling device stores a different facility ID for each device, and when the press of the taxi calling button is detected, the stored facility ID is wirelessly transmitted to the server by the LPWA communication function. The taxi vacancy notification device has a button that is held in a pressed state and a non-pressed state, and only when the vacant car button is held in a pressed state, the LPWA communication function is used in advance. The taxi ID that is different for each stored taxi is associated with the current location information from GPS and sent to the server every minute (the server also has an LPWA communication function). The facility ID and the location information / facility name of the facility are stored in the server in advance, and when the facility ID is sent to the server, the taxi company has an application that runs on the installed tablet. The group of the location information of the facility, the facility name, the location information of the taxi that is within the predetermined range from the location of the facility and the location information has been transmitted up to the predetermined time, and the taxi ID are notified by push notification. When the tablet app receives this push notification, the taxi position and current location information reception time, facility location and facility ID reception time are displayed on the map. The taxi dispatcher of the taxi company looks at the displayed taxi position, facility position, and reception time of each, and touches the taxi to be dispatched from the displayed multiple taxis. The tablet uses the taxi ID of the touched taxi as the taxi ID to be dispatched and transmits it to the server together with the facility ID of the corresponding vehicle dispatch destination. The server uses the LPWA communication function to send the facility name and facility location information of the facility ID of the dispatch destination to the vacant vehicle notification device of the taxi ID, and the taxi location information of the taxi ID to the taxi calling device. Information on the estimated arrival time calculated from the route between the taxi and the location information of the facility to which the taxi is dispatched is transmitted. When the taxi calling device receives this, it displays on the display that the taxi is being dispatched and the estimated arrival time. The vacant vehicle notification device of the taxi ID that has received the facility name and facility location information of the facility ID of the vehicle dispatch destination displays the route to the facility of the vehicle dispatch destination on the display device using the received information and also vacant vehicles. Releases the hold of the button being pressed.
In this way, the taxi requester can call the taxi with the touch of a button. For facilities such as stores, it is only necessary to install simple devices that are smaller than smartphones and do not require charging of batteries near cash registers and waiting areas. The taxi company will know the taxi near the client and will be able to deliver it to the requested location.
The taxi calling device may be provided with a taxi recall button to similarly transmit to the server that the taxi has been recalled. In addition, the taxi calling device is equipped with a function to input the number of vehicles desired to be dispatched, and information on the number of vehicles is also transmitted. It may be displayed on a map to accept selections from the map of the number of taxis. Further, it may be provided with a function of displaying a list of press time of the call button and canceling the one in the list that has been pressed by mistake. In this case, the information to the effect of cancellation, the information of the number in the list to be canceled, and the facility ID are sent to the server side, and the server side displays the information to the effect of cancellation on the map display based on this information. At the same time, if the vehicle has already been dispatched, the cancellation information is delivered to the taxi calling device and the vacant vehicle notification device. In response to this, it is advisable to make each device display the fact of cancellation and return the empty car button to the state where the empty car button is pressed. In addition, the server may be a blockchain server, and in particular, a blockchain shared by tablet apps of multiple taxi companies.
Further, for example, it is preferable that the so-called golf navigation system is provided with an LPWA communication function and has a function of transmitting information on the user's hitting position to the server side by the LPWA communication function. For example, in a golf course, the golf navigation system has a function of notifying the distance from the current position measured by GPS or the like to the pin position of the hole of the course currently being played, which is stored in advance, and the user at the position where the ball is hit. It is particularly preferable to have a point registration button to be pressed by the button and to send the position information of the position where the point registration button is pressed to the server by the LPWA communication function. Further, it is preferable to have at least one of the following functions, and preferably to have all the functions. It is preferable to have a function to memorize the position registered by pressing the point registration button. It is preferable to have a function to memorize the position registered by pressing the point registration button. It is advisable to associate the time information of the time when the point registration button is pressed with the information of the position to be transmitted by LPWA and transmit it. The transmission by LPWA may be performed immediately when the point registration button is pressed, but it is detected by the cup-in detected by the button for inputting the cup-in instruction from the user or by GPS. The position of the point registration button in the hole you were playing before the move, based on at least one of the current positions being moved to or initiated from another previously stored hole position. It is particularly preferable to collectively send the history of information to the server side by the LPWA communication function. Further, it is preferable to have a function of transferring the position stored after playing to another device such as a PC, or a function of displaying the position on the hole corresponding to the stored position together with the schematic diagram of the golf course.
In addition, it is preferable that the so-called radar detector is equipped with an LPWA communication function and has a function of transmitting sighting information such as crackdowns from the user to the server side by the LPWA communication function. The location information when the post button is pressed by the user may be transmitted to the server side by the LPWA communication function together with the time information when the button is pressed.

(2-1) When other types of data are, for example, pre-processed data (for example, so-called raw data), the specific type of data may be these post-processed data.

It is advisable to perform processing in which the data before processing is used as the data after processing.
The data before processing may be, for example, data detected and measured by a sensor, a measuring device, or the like, data indicating the substance, or the like.
The data before processing may be, for example, text data, while the data after processing may be binary data.

The processed data may be, for example, data obtained by applying lossless compression, lossy compression processing, or the like focusing on redundancy or the like to the data before processing.

Further, the data after processing is, for example, representative values and statistics such as additive mean value, synergistic mean value, median value, mode value, etc. obtained by performing statistical processing on a plurality of data before processing. It is preferable to use data indicating. For the processed data, for example, statistical values obtained by statistically processing the sample data for the accident sample data, learning model data generated by performing machine learning on the sample data, and input and output of the training model data are used. It is preferable to use the distillation model data or the like generated as a result. Machine learning may be used, for example, for predicting equipment failures.

Further, in artificial intelligence, especially in artificial intelligence that performs deep learning, the trained model data deserves statistical information compression of the data used for learning, so the amount of data is larger than that of the data used for learning. small. Therefore, it is preferable that the data before processing is used as the data used for the above-mentioned learning, and the data after processing is used as learned model data or the like used in artificial intelligence. Further, in particular, the processed data may be, for example, the number of layers of the neural network, the number and configuration of neurons in each layer, the network connection configuration and its weight between each layer, the firing function and its threshold value, and the like. Further, in particular, the processed data may be limited to the part that changes due to learning. In particular, the processed data may be weight data. In this way, a particularly excellent effect is exhibited in normal learning in which the static configuration of the neural network is not dynamically changed. It is preferable to use a format in which the processed data can be exported from a plurality of frameworks and the size is relatively small. In particular, NNEF may be used, but ONNX (Open Neural Network Exchange Format) is recommended.

In this system, for example, when a sign or a vehicle is image-recognized and identified by the trained model data, the initial model is stored in the drive recorder at the time of shipment from the factory. If there is an error in image recognition, it is advisable to have the user press an operator such as a button as an input for correction. In this system, the user's correction of this error should be supervised learning and implemented on the edge side (drive recorder in this example). As a result, a derivative model is created on the edge side with respect to the initial model. Moreover, a large number of derivative models will be created in parallel with the drive recorders of multiple vehicles. The edge side in this system may send this derived model to the server at a predetermined timing. The predetermined timing may be the timing when the mileage of the vehicle reaches the predetermined distance, or the timing when it is detected that the amount of change in the model has increased, but the evaluation result based on the evaluation image data is improved on the edge side. It is especially good to set the timing when is seen. The improvement of the evaluation result may be determined, for example, by comparing the numerical value, which is an index of the evaluation included in the evaluation result, with the threshold value.

In this system, the information used for learning on the edge side is recorded on a removable medium such as an SD card, and when connected by a communication means other than LPWA, this information is associated with the learning data on the server together with the information. You should send it.

On the server side, the model data sent by this system from the drive recorder of each vehicle is evaluated using the evaluation image, and the best one is simultaneously distributed from the server to the drive recorder that has not been learned yet. This is especially good because it seems that a significant number of people do not press the button even if they make a mistake, that is, they are users who use the defaults without cooperating with learning.

On the other hand, this system should not be distributed to drive recorders that are individually learning. In addition, this system distributes data to drive recorders that are being individually learned, and which of the model data distributed on the edge side and the data currently learned by that drive recorder has higher performance? It is better to evaluate and adopt the one that is good. This is because the content of the image changes depending on the mounting method of the drive recorder and the like, so that the model data highly evaluated on the server side is not always the optimum model data for the image of the drive recorder. When there are a plurality of edge sides (drive recorders, etc.) that have not been learned yet, the server may send the best model data to each of those edge sides on a one-to-one basis, but as described above, LPWA is used. It is advisable to broadcast all at once using connectionless communication.

When the derived model is transmitted to a server or the like, this system blocks the hash value of the model data together with the ID of the edge device that generated the derived model, the ID of the owner of the edge device, and preferably both of them. Write to the chain. In this way, the right holder of the derived model can be easily identified.

Further, the data after processing may be, for example, data extracted from the data before processing by satisfying a predetermined condition.

The processed data may be, for example, data extracted from the data obtained by measuring the behavior related to driving for calculating the insurance premium.

Further, when the data before processing is, for example, POI (Point of interest) data before change, the data after processing may be the difference between the POI data before and after the change.

Further, the data after processing may be data or the like extracted at a certain point in time from a plurality of data before processing whose values may fluctuate with time.

When the data before processing is, for example, entity data representing an object indicating an entity, the data after processing may be data indicating the result of determination by a machine or a human with respect to the entity data. .. The data after processing may be, for example, a comparison result between the data before processing and the threshold value.

The processed data is, for example, data indicating the result of recognizing the image with respect to the image data indicating the image itself, information indicating whether or not the measured value exceeds the threshold value with respect to the measured value of impact, and the behavior of the user itself. Information that labels the behavior of the data indicating the CAPTCHA, data indicating the result of the user recognizing the CAPTCHA for the image for CAPTCHA, and whether or not the measured value exceeds the threshold value for the measured value of alcohol intake. It is preferable to use data showing the inspection result for the judgment result of the danger of drunk driving indicated by the above, the measured value of the maintenance inspection target of the vehicle, etc.
On the receiving side, it is advisable to perform a process of writing the received processed data to the blockchain.

(2-2) When other types of data are, for example, a plurality of certain data, the specific type of data may be identification information or the like assigned to specify the data.

The specific type of data may be, for example, information about the vehicle detected at the timing of imaging, recording, or recording of each data of an image captured around the vehicle, a recorded moving image, and a recorded voice. For example, when the drive recorder included in this system communicates information about this vehicle as specific type of data, it is not possible to send a video, but it is possible to contact only the location data and the occurrence of an event such as an accident.

The specific type of data may be, for example, identification information used for identifying the game item with respect to image, video, and audio data indicating the game item itself.

Further, the specific type of data may be, for example, a URI (Uniform Resource Identifier) used for identifying the web content for each data of the web content. Also, for example, it may be a URL. In particular, the URL should be generated as a URL processed (converted) from the actual URL into the URL of the shortened URL service.

The specific type of data may be, for example, detection data indicating that the machine has detected the target, report data for reporting that the user has found the target, or the like.

The specific type of data is, for example, detection data indicating that a radio wave (radar wave) output by an automatic speed violation control device or a radio wave of a specific frequency used in police radio or the like has been detected by a radio wave detector. It is good to say.

In addition, for specific types of data, for example, an image taken on the road is analyzed, and the image recognizes a traffic mobilizer, a police officer, or the vehicle (police car or motorcycle) and detects them. It is good to use the detection data shown.

Further, the specific type of data may be, for example, report data for reporting that the user has found an automatic speed violation control device or a traffic mobilization member by visual inspection or the like.

This system is equipped with a detection device that measures the position of the detection device itself by, for example, a Global Navigation Satellite System (GNSS), and a notification button for an automatic speed violation control device inside the vehicle. It is preferable that the system is provided with a server, and when the user presses this notification button, the detection device sends a coordinate value indicating its own position to the server. As a result, this system can collect big data of speed violation control performed in real time. In addition, the server in this system may acquire congestion information in addition to the coordinate values.

This system is equipped with a detection device for detecting abnormal situations such as intrusion and fire in the user's home or automobile, and when these abnormal situations occur while the user is away and are detected by the detection device. In addition, it is advisable to notify the user by e-mail or the like as a specific type of data such as a notification that an abnormal situation has been detected.

In particular, this system also includes an image pickup device, and when the detection device detects the occurrence of the above-mentioned abnormal situation, it is preferable to send the image captured by the image pickup device. When an abnormal situation occurs, for each occurrence of the abnormal situation, for example, a 20-byte command header, 16-byte date and time data, and 4-byte data indicating the type of the abnormal situation are included. A total of 40 bytes of data are sent to the server. Further, it is preferable that a total of about 40 kilobytes of data is sent to the server by adding 327 × 252 (82404 pixels) image data in addition to the above 40 bytes of data.

When a total of about 40 kilobytes of data is sent to the server for each occurrence of an abnormal situation, for example, if 10 abnormal situations are detected in a month, a total of 400 kilobytes of data per month will be detected. Is sent. The mail used for transmitting data may be sent to a server, and the server may send the mail to, for example, a user's smartphone (hereinafter, also referred to as "smartphone") or a mobile terminal. In this case, it is possible to reduce the amount of data on the server as compared to the case where it does not go through the server. The above e-mail may be sent directly to the user's smartphone or the like as a free e-mail or the like.

When the other type of data is, for example, image data indicating an image or voice data indicating voice, the specific type of data may be character data indicating characters or the like.

SNS data such as Twitter and Instagram mainly consists of character data, image data, and video data. Of these, the system may send only character data, and image data and moving image data may be sent by a communication means other than LPWA. In this system, in order to link character data and image data, etc., information should be added to each and sent, and the correspondence between the two should be linked and processed on the server side.

When other types of data exceed, for example, an amount that can be recognized, stored, input, etc. at one time by humans, the specific type of data is defined as data that does not exceed this amount. Good.

For example, in the case of character data, the specific type of data may be character data within the optimum number of characters to convey a cohesive meaning.

As an example of the optimum number of characters to convey a unified meaning, for example, a general number of characters that can be described in a postcard may be used. Further, as an example of the optimum number of characters for conveying a unified meaning, for example, 70 full-width characters or 160 half-width alphanumeric characters adopted in the short message service (SMS) may be used.

In particular, the specific type of data may be character data within the number of characters that human beings can memorize at one time by short-term memory, for example.

As an example of the number of characters that human beings can memorize at one time by short-term memory, for example, about 3 to 9 characters are good.

Due to the nature of the type itself, the amount of data of a specific type may be smaller than that of other types of data.

Certain types of data include, for example, information for authentication, credential consisting of a user ID and password pair, driver's name written on the license or electronically stored, date of birth, home address, etc. Identification information, vehicle information, data indicating roll call, data that detected an intruder indoors while away, hash value for blockchain, etc., data generated in one transaction in the blockchain, time stamp, Ethereum Scripts and source codes of contract-oriented languages such as Solidity used in blockchain platforms such as, hash tags used in SNS, etc., identification information such as stamps and pictograms used in SNS, contact input data, count results Data indicating, opening / closing detection data such as a thumb turn, permission information permitted by the user when downloading or executing an application program (referred to as an application), weight measurement data of the contents, etc. may be used. The system may use certain types of data, for example, as evidence.

The above-mentioned information for authentication may be, for example, a driver's license reading device provided in the automobile, an alcohol checker, a user's (driver's) license, a check result regarding a drunken state, or the like. The device installed in the car sends these check results to the server before the start of operation. In particular, it is preferable to transmit information in which information for identifying the driver (for example, driver ID) and information on the check result are associated with each other.

For example, the data sent in one operation is a total of 36 bytes including a 20-byte command header, a 12-byte license number data, and a 4-byte alcohol measurement result. .. In this case, once a day, the amount of communication is about 1 kilobyte per month. The server should manage the history.

The hash value for the blockchain or the like described above may be a hash value recorded when a user who uses the blockchain distributed database updates the distributed database. The block itself increases with each update, but the hash value of the block at a certain point in time is smaller than that of the block itself, so the amount of data transmitted is suppressed. The contents of the publicly available distributed database can be referenced and updated by participants in the blockchain, and the hash value of the previous block is entered in the next block, so it is virtually impossible to tamper with the block information. Therefore, it is extremely useful for data storage and distribution between people with conflicting interests. Due to these characteristics, blockchain is widely used not only for virtual currencies but also for distribution, for example. This system sends a hash value indicating from which vendor to which vendor the shipment is currently delivered as a specific type of data and records it on the blockchain to trace the objects among those who participate in the supply chain. Should be complete and easy. In addition, this system may be used, for example, between a person who bought an advertising space (advertising company) and a company that sells the advertising space (advertising agency, etc.). Furthermore, this system may transmit a hash value indicating the performance status of all contracts with conflicting interests as specific types of data and record it on the blockchain. In addition, the system may send a script as a specific type of data and record it on the blockchain so that the program automatically executes the next contract or factual act according to the execution of the contract.

Further, the above-mentioned "data generated by one transaction in the blockchain" is data generated every time the distributed database of the blockchain is updated. This data is, for example, only the amount of information about who transferred to whom and how much in the case of virtual currency. Therefore, the system may transmit this data as a specific type of data.

In addition, the system may be set to execute smart contracts when it detects that the sensor has entered a specific state or that a specific operation has been performed by the user.
This system is set as a condition of smart contract to execute a contract that raises the insurance premium by 0.1% when acceleration corresponding to dangerous driving is detected at the time of insurance contract, for example. In addition, this system is set as a condition of smart contract to execute a contract that reduces insurance premiums by 0.1%, for example, if a situation equivalent to safe driving continues for a predetermined period. When these conditions are met according to the operating conditions, the system automatically transmits the detection result as a specific type of data and writes it to the blockchain. This enforces these contracts.

In addition, for example, if this system builds a model in which the unit price is charged high when the usage amount is small, the unit price is reduced when the usage amount is large, and the unit price is unlimited after that when the usage amount exceeds a specific amount. Good. In this system, the contract for the use of the car navigation system may be contracted by smart contract, for example, 2 yen per 1 km up to the first 5000 km, 1 yen per 1 km from 5000 km to 20000 km, and free of charge for 20000 km or more. In addition, when the user operates the car navigation system and presses the purchase instruction button for map update, the system may execute a smart contract for map update purchase. Here, since the amount of information in the map update data is large, it is updated by communication means other than LPWA, SD distribution, etc. After that, in addition to the above navigation amount, after the map update, up to the first 2500 km is 2 yen, 10000 km It is advisable to execute a smart contract such as 1 yen up to 1 yen and free after that to charge.

When transmitting the above-mentioned game item identification information as specific types of data, this system can be used in addition to so-called items such as weapons, armor, and medicine used in the game, as well as, for example, gacha execution and crystal. It is advisable to record on the blockchain the identification information of the right to be granted purchases, shortened time to the event, and other favorable conditions.

In addition, this system may record information related to input of user authentication information and acceptance of access right information in the blockchain. For example, this system may send authentication information consisting of a set of a user's ID and password, and record information on the pros and cons of the authentication result on the blockchain. Further, for example, information on whether or not an instruction for permission to access the hardware / software resources of the application has been given may be recorded in the blockchain together with the information for identifying the application and the content of the permission.

In addition, it is difficult to hand over keys in so-called private lodgings where travelers and the like stay in ordinary private houses. This system may send key information indicating the key in a private residence, opening / closing information for detecting the opening / closing of a door, etc. to a server or the like by LPWA. Since the amount of data of a specific type such as key information and open / close information is smaller than that of other types of data such as video data, this system consumes less power when sending data to a server or the like by LPWA. Suppress compared to sending other types of data. This system should generate and send the hash value of the key information itself instead of sending it to the server.

Further, when the server or the like receives the key information, the hash value of the key information, the opening / closing information, etc., it is preferable to write these together with the information of the received time in the blockchain. Since the blockchain is tamper-resistant, it should be used as proof of accommodation records in private lodgings.

Further, the server or the like may be linked with the thumb turn that opens and closes the door, or may communicate with the device that drives the thumb turn by LPWA. The server or the like should authenticate the key information received from this system, and when the authentication is successful, instruct the device that drives the thumb turn to unlock the key. Since the power consumption is suppressed by LPWA, the suppressed power is used to drive the thumb turn, and the battery life is relatively long.

Further, the power consumption suppressing means is a communication means as a specific type of data, in which data indicating the result of determination by edge computing in association with the above-mentioned contact input for a large amount of information output in chronological order is used. It is good to send to. Examples of the large amount of information output in time series include output from various sensors such as microwave sensors, audio, video, and the like. Examples of the content of edge computing include a process of recognizing only a large amount of information output in a time series while the contact state is on. That is, in this system, for example, if the above-mentioned "thing with a large amount of information" is an image, the contact point is turned on by the probability vector of the result of recognizing an object or the like included in the image through a deep learning model. It is advisable to send it to the communication means together with the time information of.

The above-mentioned data showing the counting result shows the traffic volume counted (counted) by human power or machine in the traffic volume survey conducted all over the country for, for example, new road construction and other city planning. Data etc. can be mentioned. In the work of counting the traffic volume, it is necessary for one person to operate 4 to 8 counters in order to record what kind of moving object has moved from which direction to which direction. In addition, at intersections where many people and cars come and go, 4 to 10 observation points are required at one intersection, and an observer is required for each of these observation points. Therefore, this work involves changing observers. It is necessary to secure about 8 to 20 people including personnel. Therefore, there is a problem that labor costs are high, it is difficult to secure human resources, and the measurement accuracy is poor.

Therefore, this system may count the traffic volume by the camera and the image recognition, and have the communication means transmit the count result. As the count result, it is sufficient to send the aggregated result of one day, so that the communication amount of the communication means in this system is about several tens of bytes per day.

The contacts and the like that generate the above-mentioned contact input may be attached to, for example, a delivery box. In this system, when a courier company or a participant who participates in the sharing economy as a service provider puts a package in a delivery box, the above-mentioned communication means may transmit a package delivery completion signal. Further, in this system, a weight scale such as an electronic balance or a spring scale is installed in the delivery box, and the weight measurement data obtained by measuring the weight of the contents contained in the delivery box is used as the above-mentioned communication means. It is good to send to.
It is advisable to perform a process of recording specific types of data in a distributed ledger such as a blockchain, while recording other types of data in a predetermined server of a general database (relational database, NoSQL database, etc.).

(2-3) When the other type of data is data that has already been transmitted by, for example, a communication means other than LPWA, the specific type of data may be data other than the transmitted data.

The specific type of data is data other than the data already transmitted by other communication means other than LPWA, such as smartphones, proximity communication, 4G, 5G, etc., among the data that can be transmitted by the communication means by LPWA controlled by this system. It should be selected from among.
The system may not transmit the already transmitted data, especially by a communication means other than LPWA.

(3) The power consumption suppressing means may be a system that does not allow the communication means to transmit data indicating an image.

The amount of data to be transmitted is smaller than that in the case of transmitting video.
As the content of the control for controlling the communication means so as to suppress the power consumption, it is preferable to control the power consumption suppression means so as not to transmit the data showing the image to the communication means. Further, as the content of this control, it is preferable to control so that the data indicating the video is not transmitted to the communication means and, for example, to transmit the specific type of data shown in (2).

(4) The power consumption suppressing means may be a system that does not allow the communication means to transmit the data under a predetermined situation even if there is data to be transmitted.

Power consumption due to data transmission is suppressed under certain circumstances.
The data to be transmitted may be, for example, the specific type of data shown in (2).

The determined situation may be a situation in which the environment of this system satisfies or does not satisfy the determined conditions. The environment of this system may be, for example, time, elapsed time, position such as latitude / longitude / altitude, communication environment, available electric energy, presence / absence of acquisition of information or signal, and a combination thereof.

The determined conditions may be a combination of a plurality of conditions. The determined conditions may be predetermined rules, patterns, combinations thereof, and the like.

For example, when a system that transmits data related to a certain target detects the target under a predetermined situation, the detection itself may be incorrect. For example, when the system detects radio waves in a predetermined band output by an automatic speed violation control device or the like, the radio waves in the same band may be used for automatic doors of various stores such as convenience stores. In this system, if a detection device controlled by this system enters within a certain distance from the store during business hours of these stores, radio waves emitted from an automatic door or the like different from the intended purpose may be detected.

This system measures the position of the detection device by, for example, GNSS, specifies the current time and the position of the detection device, and determines whether or not the detection device exists at a predetermined time and place. .. Then, when the system determines that the detection device exists at that time and place, it is preferable not to transmit the detection data indicating the detection. As a result, unnecessary data transmission is suppressed under a predetermined situation, specific types of data to be transmitted are further thinned out, and power consumption due to data transmission is suppressed.

(5) The power consumption suppressing means may be a system that transmits acquired acquired data at adjusted intervals.

The amount of data to be transmitted is smaller than that in the case where the acquired data is transmitted at unadjusted intervals.

The adjusted interval is defined as an interval that is at least longer than the interval for acquiring the acquired data so that the number of times the data is transmitted is less than the number of times the acquired data is acquired in a predetermined period such as one day or one week. Good.

The adjusted interval may be, for example, an integral multiple of the interval at which the acquired data is acquired (however, the integer referred to here is a positive integer excluding 1). If the adjusted interval is, for example, N times the interval at which the acquired data is acquired (N is an integer of 2 or more), the data is transmitted only once every N times when the acquired data is acquired.

For example, this system has data indicating the start date and time and end date and time (16 bytes each = 32 bytes) and vehicle coordinate value data recorded at 5-minute intervals over 8 hours (20 bytes x 96 times = 1920 bytes). ) And to the transmitting means. This 5-minute interval is an integral multiple of the interval at which the acquired data is acquired.

In addition, when an event occurs, this system indicates a 4-byte measured value (for example, G sensor value) related to the event, 16-byte data indicating the date and time when the event occurred, and the location where the event occurred. The 20-byte data and the data are temporarily recorded and transmitted to the transmitting means. The amount of event-related data temporarily recorded is 400 bytes, which is the total of (4 + 16 + 20) bytes × 10 times, assuming that the event occurs 10 times a day. In addition, in these reports, 5 types of data of driver ID, driving time, average speed, maximum speed, and mileage are represented by 4 bytes each, and a total of 20 bytes of data contains bibliographic items. Included as shown data. Therefore, the system may send, for example, 32 + 1920 + 400 + 20 = 2372 bytes once a day. The monthly communication volume of this system is about 71 kilobytes. Since this system sends reports collectively at the end of business, the amount of data for so-called command headers such as command type and sender information can be reduced.

Also, the adjusted intervals do not have to be constant. The adjusted interval may be, for example, an indefinite interval determined as a result of transmission at a timing satisfying a predetermined condition. The timing at which the predetermined condition is satisfied may be the timing at which the system acquires a signal indicating the switching of the business contents of the monitored person monitored by the system. In this system, for example, when the monitored person is performing delivery work, it is advisable to collectively send the acquired data at the timing when the monitored person completes a series of work from depositing one package to delivering it to the destination. .. The timing at which the delivery operation is completed may be determined, for example, at the timing when the barcode reading device reads the barcode written on the copy to be delivered to the delivery destination at the time of delivery.

Further, this timing is a signal indicating that the monitored object of the system has reached a predetermined position, a signal indicating that the moving distance of the monitored object has reached the threshold value, and the moving speed of the monitored object has exceeded the threshold value. It is advisable to set the timing at which the system acquires various signals related to the monitoring target, such as a signal indicating that the signal has fallen below the limit. Further, this timing is preferably the timing when a taxi or the like gets on or off the passenger. Further, this timing is preferably the timing when the truck or the like loads the cargo or the timing when the truck or the like unloads the cargo.

Further, this timing may be the timing when the engine is started or turned off, the timing when the light is turned on or off, and the timing when the character opens or closes the door.

Further, this timing may be the timing at which the system receives a control signal corresponding to the operation from the server device, the smartphone, or the like that has received the user's operation.

Examples of the predetermined conditions described above include conditions such as whether or not the engine is stopped. For example, LTE-M has a function to adjust the transmission interval of radio waves like eDRX. In the vehicle, when the engine is stopped, it is preferable to control the transmission interval of radio waves to be longer than when the engine is started.

(6) The power consumption suppressing means may be a system in which the acquired acquired data is transmitted to the communication means at intervals adjusted based on the information indicating the contract contents of the LPWA of the user.

The amount of data to be transmitted varies depending on the user's contract details. Information indicating the contract contents of LPWA is stored in storage means such as a cloud or a server device, and the system may acquire information indicating the contract contents of LPWA from these storage means. The system may adjust the interval at which data is transmitted based on this information obtained. For example, when the user presses the notification button of the above-mentioned automatic speed violation control device, it is preferable to reduce the communication volume by setting the interval for transmitting the detected coordinate values to be larger than the detection interval.

For example, when the above-mentioned coordinate values are sent at 5-minute intervals, the amount of data per month is, for example, 115 kilobytes. Further, each time the above-mentioned notification button is pressed by the user, the detection device is a total of, for example, 16-byte date and time data, 20-byte coordinate value data, and 20-byte command header data. Sends 56 bytes of data. The data indicating the date and time is transmitted because it is necessary to resend the data if the transmission fails. This system sends 224 bytes of data in a month, assuming that the report is made once a week. Further, if the reported information is received 10 times a month, the system receives 560 bytes of data in a month. Summing up these, the amount of data per month is, for example, 116 kilobytes.

(7) The power consumption suppressing means may be a system in which the acquired acquired data is processed so that the amount of data to be transmitted is smaller than that of the acquired data, and the processed data is transmitted.

The amount of data to be transmitted is smaller than that in the case where the acquired data is transmitted without processing. It is preferable that the acquired data corresponds to the other types of data described above, and the processed data corresponds to the specific type of data shown in (2).

For example, when the data before processing is text data including one or more messages, rows, etc. composed of one or more fields, columns, etc., the data after processing is a specific message or row from this text data. However, it is preferable that the data is obtained by extracting only specific fields or columns.

For example, when the data before processing is text data generated in accordance with standards such as NMEA 0183 (hereinafter, simply referred to as "NMEA") regulated and managed by the National Marine Electronics Association. The processed data may be data obtained by extracting only some types of messages such as RMC messages and GGA messages. When the user presses the report button of the automatic speed violation control device described above, it is preferable to send only the coordinate values by GNSS or the like to the server instead of sending the so-called raw data such as NMEA.

(8) The power consumption suppressing means has a function of processing the acquired acquired data so that the amount of data to be transmitted is smaller than that of the acquired data, and causes the communication means to transmit the processed data, and the acquired data. It is preferable that the system has a function of transmitting the data as it is to the communication means.

Not only the data after processing but also the data before processing can be transmitted.
On the receiving side, while the received processed data is recorded on the blockchain, the received acquired data is recorded on a predetermined server of a general database (relational database, NoSQL database, etc.). Good.

(9) The power consumption suppressing means may be a system in which acquired data acquired under a predetermined situation is processed so that the amount of data to be transmitted is smaller than that of the acquired data, and the processed data is transmitted. ..

Power consumption due to data transmission is suppressed under certain circumstances.
The determined situation may be the situation shown in (4).

(10) The power consumption suppressing means processes the acquired acquired data so that the amount of data to be transmitted is smaller than that of the acquired data according to the degree of the event detected in the target device. It is good to have a system that sends later data.

The degree to which the amount of data to be transmitted decreases depends on the degree of the event detected in the target device.

The target device may be, for example, a vehicle, and the detected events may be the posture, orientation, position, impact applied to the vehicle, pressure applied to the vehicle, temperature of the vehicle, and the like.

When it is detected that the vehicle is in a predetermined posture, for example, the vehicle is turned upside down, the system processes the acquired data to the first level so as to reduce the amount of data, and transmits the data in a posture other than the predetermined posture. When it is detected, it is preferable to transmit the processed data obtained by processing the acquired data to the second level, which has a smaller amount of data than the first level.

(11) The power consumption suppressing means may be a system that transmits data according to the acquired acquired data when one or more events detected in the target device satisfy a predetermined condition.

The transmission of data according to the acquired data is determined depending on whether or not the event detected in the target device satisfies the determined condition.

The target device is, for example, a vehicle and a driver of the vehicle, and the detected events are the posture, orientation, position of the vehicle, the impact applied to the vehicle, the pressure applied to the vehicle, the temperature of the vehicle, etc., and the driver's arousal level. , Eye open state, eye opening, number and speed of blinking, respiratory rate, heart rate, etc.

For example, when the driver is determined to be in a dozing state as a result of detecting the driver's arousal level and an impact exceeding the threshold is applied to the vehicle, the system does not process the acquired data or the first method. Processing is performed to the standard, and the acquired data itself or the processed data processed from the acquired data, that is, the data corresponding to the acquired data is transmitted. For example, when the driver's dozing state or looking away / looking aside is detected and the vehicle is impacted above the threshold value, the system acquires the second level, which has a smaller amount of data than the first level. It is advisable to send the processed data after processing the data.
(12) The power consumption suppressing means processes the acquired acquired data based on the information indicating the contract contents of the LPWA of the user so that the amount of data to be transmitted is smaller than that of the acquired data, and after processing. It is good to have a system that sends data.

The degree to which the amount of data to be transmitted is reduced varies depending on the contents of the LPWA contract of the user.

The information indicating the contract contents of LPWA may be stored and acquired in the manner shown in (6), for example. The system may acquire information indicating the contract contents of LPWA and process it so that, for example, the smaller and limited the amount of data that can be communicated, the smaller the amount of data to be transmitted.

(13) The power consumption suppressing means is the remaining amount of data permitted to be transmitted to the user based on the contract contents of the LPWA so that the amount of acquired data to be transmitted is smaller than that of the acquired data. It is advisable to use a system that processes according to the above and sends the processed data.

The degree to which the amount of data to be transmitted decreases depends on the remaining amount of data permitted to be transmitted to the user based on the LPWA contract details.

The information indicating the contract contents of LPWA may be stored and acquired in the manner shown in (6), for example. The remaining amount of data permitted to be transmitted by the user based on the contents of the LPWA contract may be, for example, the remaining amount of data that the user is permitted to transmit under the LPWA contract.

For example, if the user has an LPWA contract that allows a predetermined amount of communication for each renewal date of each month, the amount of data communicated by that renewal date is subtracted from the contracted monthly data amount. As the update date approaches, the remaining amount of data decreases. In this configuration, for example, when the remaining amount of data is low before the update date, the amount of data is processed to be smaller than when the remaining amount of data is sufficient. As a result, the remaining amount of data is less likely to be insufficient as compared with a system that does not have this configuration.

(14) The power consumption suppressing means may be a system that adjusts the interval for searching for a transmission destination.

Compared to the case where the interval for searching the destination is not adjusted, the power consumption is suppressed.

The communication means controlled by this system may have a function of searching for a destination, and may further have a function of adjusting the search interval from the outside. In addition, this system should have a function to search for a destination. Further, it is particularly preferable that both the system and the communication means controlled by the system have a function of searching for a destination.
In particular, the power consumption suppressing means of this system may adjust the interval for searching the transmission destination of the communication means.

It is preferable that the system has a means for receiving an instruction from the user, and forcibly restarts the search for the destination when the instruction from the user is received even at the interval of searching for the destination.

(15) The power consumption suppressing means may be a system that adjusts the time interval for stopping the search for the transmission destination.

The power consumption is reduced as compared with the case where the time interval for stopping the search for the destination is not adjusted.
The communication means controlled by this system may have the function shown in (14).
In particular, the power consumption suppressing means of this system may adjust the time interval for stopping the search for the transmission destination of the communication means.

The time interval for stopping the search for the transmission destination of the communication means may be an interval between timings that satisfy a predetermined condition. Examples of the predetermined conditions described above include conditions such as whether or not the engine is stopped. For example, LTE-M has a power saving mode (PSM). In the vehicle, when the engine is stopped, it is preferable to control the stop interval of the radio wave search to be longer than when the engine is started.

When the time to stop the radio wave search is set to the maximum time, the radio wave search starts again after the maximum time has passed. Therefore, it is preferable that this system has a function of stopping the radio wave search at the maximum time if the base station is not found in the radio wave search after the lapse of the maximum time.

This system sets the radio wave transmission interval relatively short immediately after stopping the radio wave search for a fixed time and then restarting this radio wave search, and then increases the transmission interval as time elapses. It is good to control it.

(16) It is preferable to use a system that controls another communication means having a communication method different from that of the communication means.

Compared with the case where the communication means and the specific method communication means are operated at the same time, the power consumption is suppressed. In particular, the power consumption suppressing means may have a function of switching between the communication means and the other communication means.

Other communication means include 3G, LTE, 4G, 5G, Wi-Fi, Bluetooth (registered trademark), DSRC (Dedicated Short Range Communications), Electronic Toll Collection System (ETC), and other non-LPWA communications. It is preferable to use a communication method that adopts the method.

In addition, module replacement in basic technology edge computing Some edge-side devices for edge computing can replace communication modules. Therefore, the other communication means may be configured to be replaceable with this system. This system has a function of detecting whether or not a replaceable other communication means is available, and the power consumption suppressing means of this system communicates with the communication means by another method according to the detection result. It is preferable to have a function of switching between means. That is, it is preferable that this system detects the type of the communication module inserted in the device on the edge side and selects the communication destination and the communication data according to the type of the communication module. In this system, for example, if the communication means is not connected and the Wi-Fi module is inserted as another communication means, all communication including images and videos is performed by the Wi-Fi module. , When the other communication means is not connected and the LPWA module is inserted as the communication means, it is preferable to store the images / moving images in the local storage without communicating. The system may transfer the stored information by the Wi-Fi module, for example, when the Wi-Fi module is connected.

Also, for example, when both the LPWA module and the Wi-Fi module are plugged in, LPWA communicates information other than images / videos (data whose amount of data exceeds a certain amount), while images / videos etc. It is good to communicate with the Wi-Fi module.

Further, for example, when LPWA is used for an in-vehicle device (car security, door lock, etc.), it may fall into a state where it cannot be used at all outside the service area. In particular, there may be a situation in which the door can be locked when getting off, but the door cannot be unlocked due to interruption when getting on, or a state in which it becomes impossible to even notify the user's handheld terminal (smartphone) of out-of-service from the on-board unit.

In this system, in order to prevent falling into the above-mentioned state, it is preferable to provide a terminal (smartphone) owned by the user and a spare communication means by Bluetooth or the like. That is, when the LPWA is out of service area or out of service, the system may use a connection by a spare communication means to guarantee the user's out-of-service / out-of-service notification to the terminal and the minimum use of functions. Here, the guaranteed function may be limited to, for example, only door lock / unlock among the plurality of functions of the spare communication means. It is desirable that the establishment of communication in the spare communication means is not conscious of the user.

Further, in this system, for example, a setting for a user to use another communication means may be read from a server by using a communication means by LPWA and supplied to the user's terminal. In this system, the user's terminal may be directly connected to the Internet (server) via the LPWA base station so that the terminal itself prepares the usage environment independently. As a result, the user does not need to set the connection of the network-using product having complicated functions, and the complexity for using the product is reduced.

(17) The communication means may be a system having a first communication means that communicates with a server device that stores data and a second communication means that does not communicate with the server device.

Compared with the case where the first communication means and the second communication means are operated at the same time, the power consumption is suppressed. In particular, the power consumption suppressing means may have a function of switching between the first communication means and the second communication means.

As the server device for accumulating data, for example, a server device included in the cloud provided by SIGFOX or the like may be used.
The first communication means for communicating with the server device may be, for example, SIGFOX or the like.
The second communication means that does not communicate with the server device may be, for example, LoRa or the like. It is preferable that the second communication means does not directly communicate with the server device by the LPWA communication method. The second communication means is indirectly connected to another network via, for example, a gateway device included in the network formed by the second communication means and connected to another network by a communication method other than LPWA. It is good to include the one that interacts with the server device.

This system has a first communication means that communicates with the server device and a second communication means that does not communicate with the server device. For example, the communication function of LoRa and cellular LPWA (for example, LTE-M), LoRa and Wi-Fi. It has a combination of communication functions and so on.
Then, this system acquires data from another device by communication by the second communication means and transfers it to a server on the Internet by the first communication means.

In this system, for example, a drive recorder equipped with a communication means by Wi-Fi may be provided with functions such as remote control operation by LoRa, and the operation contents of the LoRa remote control may be transmitted at the time of Wi-Fi connection. In this case, a delay will occur when the Wi-Fi connection is not established. Therefore, when real-time operation is required, cellular LPWA or the like is desirable instead of Wi-Fi. The LoRa communication device should communicate with various sensors equipped with LoRa in addition to the LoRa remote controller, and transfer the acquired information to the server by a network connection function such as cellular LPWA.

(18) The communication means may be a system having a third communication means capable of handover communication and a fourth communication means not capable of handover communication.

Compared with the case where the third communication means and the fourth communication means are operated at the same time, the power consumption is suppressed. In particular, the power consumption suppressing means may have a function of switching between the third communication means and the fourth communication means.

As the handover communication, for example, communication for switching a base station that communicates with a mobile station while the mobile station is moving may be used.
The third communication means capable of handover communication may be, for example, LTE-M or the like.
The fourth communication means that does not enable handover communication may be, for example, LoRaWAN, SIGFOX, or the like.

The third communication means capable of the handover function tends to have a higher usage fee than the fourth communication means capable of the handover communication. Therefore, this system determines whether or not there is a high possibility that the handover is not necessary, and when there is a high possibility that the handover is not necessary, the fourth communication means may be used and the handover may be necessary. When the property is high, a third communication means is used.

It is preferable to detect whether or not the position of the moving body is moving to determine whether or not the situation is likely not to require handover. This system may determine that, for example, when the position of the moving body remains within a specific range, it is unlikely that a handover is necessary (that is, there is a high possibility that a handover is not necessary). The specific range may be, for example, a radius of several tens of meters.

This system has a function of recognizablely notifying the user whether communication is performed using a third communication means capable of handover or communication using a fourth communication means capable of handover. It is good.
The communication means includes a mobile communicable communication means capable of communicating even when the vehicle is moving at a speed exceeding a predetermined speed, and a mobile communication means capable of communicating even while the vehicle is moving at a speed exceeding a predetermined speed. It is preferable to use a system equipped with a mobile communication difficult communication means that cannot communicate.
In this way, communication can be performed even when the vehicle is moving at high speed or the vehicle is parked, and the communication amount can be distributed to both communication means, so that the communication amount is limited according to the charge. It becomes possible to use the LPWA service efficiently. The mobile communication capable communication means may be, for example, ELTRES, and the mobile communication difficult communication means may be, for example, SIGFOX.
The communication means may be a system including a GPS essential communication means that requires the use of GPS time information for communication and a GPS-free communication means that does not require the use of GPS time information for communication.
In this way, communication can be performed indoors where GPS cannot be received, communication can be performed outdoors where GPS can be received, and the amount of communication can be distributed to both communication means, so communication can be performed according to the charge. It is possible to efficiently use the LPWA service, which has a limited amount. The mobile communication capable communication means may be, for example, ELTRES, and the mobile communication difficult communication means may be, for example, SIGFOX.
If different communication means are switched to enable communication, the server side should perform a process of recording which communication means the data was received in association with the received data, especially the blockchain. If such recording is performed when recording in the server, it becomes easier to verify the reliability of the data and to identify the origin of the data.

(19) The communication means may be a system having a function of using a SIM that can be attached to and detached from the communication means and a function of using a SIM provided in the communication means.

The SIM that can be attached to and detached from the communication means and the SIM provided in the communication means can be controlled according to their respective uses. In particular, the power consumption suppressing means may have a function of switching between a SIM that can be attached to and detached from the communication means and a SIM provided in the communication means. Compared with the case where these SIMs are operated at the same time, the power consumption is suppressed.

SIMs used in LPWA include a normal card-shaped SIM that is inserted into a slot and a chip-type SIM that is soldered to a substrate. In addition to incorporating a chip-type SIM, this system may also be provided with a normal card-shaped SIM slot. This system communicates using a chip-type SIM when the SIM is not inserted in the normal SIM slot, while it is better than the chip-type SIM when the SIM is inserted in the normal SIM slot. It is preferable to perform the process of preferentially using the SIM inserted in the slot.

Further, the above-mentioned "function of switching between the SIM that can be attached to and detached from the communication means and the SIM provided in the communication means" is whether or not the engine of the vehicle is running, or the vehicle is running. It is advisable to decide the switching destination according to whether or not it is in a state. It is advisable to detect the occurrence of vibration and estimate the state of the engine of the vehicle and the state of running of the vehicle based on the degree of vibration. For example, this system may use a chip-type SIM when it is determined that vibration is generated, and a normal SIM when it is not determined that vibration is generated.

In addition, the above-mentioned function may determine the switching destination according to the temperature. For example, this system may determine whether or not the temperature is high based on the measurement result of the thermometer, use a chip-type SIM when the temperature is high, and use a normal SIM when the temperature is not high. ..

Further, it is preferable that the above-mentioned function determines the switching destination according to the location of the communication means. This system may automatically switch which SIM to use according to the location of the communication means specified by the positioning system such as GNSS.

(20) Having a first positioning means for measuring a position,
The communication means may be a system having a second positioning means different from the first positioning means.

Information that cannot be obtained by the first positioning means can be obtained from the second positioning means. In particular, the power consumption suppressing means may have a function of switching between the first positioning means and the second positioning means. Compared with the case where the first positioning means and the second positioning means are operated at the same time, the power consumption is suppressed. The second positioning means may provide information necessary for the communication means to communicate.

The first positioning means may be, for example, a positioning device using GNSS or the like built in the drive recorder, and the second positioning means may be, for example, a positioning device included in LTE-M, ELTRES, or the like.

For example, LTE-M has a positioning function. Therefore, it is preferable that this system is provided with a positioning function different from this positioning function, and has a function of selecting one of the two pieces of information as information to be used. This system should be equipped with a function that allows the user to set which positioning function to select by accepting operations, but a function that compares the output data of both and automatically selects which one to use is provided. You should prepare.

(21) It is preferable to use a system that controls the notification means to notify the user of the state of the communication means.

The user can know the changing state of the communication means in the system.

The contents to be notified to the user include, for example, the last transmission time by the communication means that performed the intermittent transmission, the information indicating the search state of the destination shown in (14) and (15), and the first information shown in (16). Information indicating which one is used in the system having the communication means and the second communication means, and the system having the third communication means and the fourth communication means shown in (17). It may be information indicating which one is used.

This system may be provided with a function of recognizablely notifying the user whether or not the radio wave search is stopped.
This system may be provided with a function of recognizable information regarding the radio wave search interval.

This system may be provided with a function of recognizable information regarding the transmission interval.

The system may have a function of recognizablely notifying the user whether a chip SIM or a normal SIM is used.

(22) The communication means is a communication means attached to a mobile body that communicates with a fixed communication means that does not move, and is a system that transmits data received from the fixed communication means at the destination where the mobile body moves. Good.

Compared with the case where data is transmitted by a communication means other than LPWA, the power consumption is suppressed.

The fixed communication means is fixedly connected to, for example, a measuring instrument such as a thermometer or a hygrometer, acquires the measured value by the measuring instrument, and transmits a signal indicating the measured value by LPWA. LoRa, NB-IoT, SIGFOX The moving body may be, for example, an automobile (truck, taxi, motorcycle) used in the transportation industry such as rail transportation, automobile transportation, ship transportation, air transportation, railroad, ship, aircraft, or the like.

The system may, for example, attach a communication means by LPWA to a moving body such as a truck of a courier company or a taxi of a taxi company. When the mobile body enters a predetermined range centered on the fixed communication means described above, the system causes the communication means attached to the mobile body to receive a signal transmitted from the fixed communication means, and the signal indicates. The data may be stored in a storage device. Then, when a moving object such as a truck or a taxi described above enters a facility such as a business office or a resting place of a courier company or a taxi operator, the data stored in the storage device is stored in the server device provided in the facility. And so on. In this configuration, for example, when the moving body moves to an area where communication is difficult, the measurement results of the measuring instruments provided in that area can be collected.

To acquire information from IoT devices in areas with poor communication conditions, one is to communicate with the edge device and the base station device and connect to the Internet from the base station device, and the other is to connect the base station device to the Internet without connecting to the Internet. Some of them communicate with each other and acquire data with base station equipment. Both devices need to be able to communicate with each other. However, for example, in mountainous areas, there are mountains and valleys, and communication may not be possible.

In this system, the LPWA communication means attached to the above-mentioned mobile body communicates with the LPWA device in a place where the radio wave condition is bad or the base station is not maintained, acquires and stores information, and connects to the base station. It is advisable to transmit these information stored at the time of the reception to, for example, a server via the base station.

(23) A second system on the side of transmitting information to the system according to any one of (1) to (22).
A second power consumption suppressing means for generating the data so as to suppress the power consumed by the communication means when the communication means receives the data transmitted from the second system side to the system side. Two systems are recommended.

The power consumption of the communication means of the system according to any one of (1) to (22) when receiving data from the second system is higher than that of the case where the second system does not have the second power consumption suppressing means. Less.

As a method for controlling the power consumption so as to be suppressed, it is preferable to use a method equivalent to the method illustrated in (2) to (22) performed by the power consumption suppressing means in the above-mentioned system.

Further, the second power consumption suppressing means may generate a specific type of data in which the amount of data to be transmitted is smaller than that of other types of data. The data generated by the second power consumption suppressing means may be, for example, data for remotely controlling the system.

That is, the second power consumption suppressing means of the second system is, for example, air conditioning equipment such as a dwelling / vehicle air conditioner, a heater, a humidifier, and an air purifier, a vehicle starting device such as a vehicle engine starter, and a vehicle starting device. It is preferable to generate the control signal for remotely controlling the control target of various devices installed in a house, a vehicle, etc., such as a car security device such as a keyless entry system and a recording device such as a drive recorder, as the above-mentioned data. .. When this second system is applied to a user's smartphone, the smartphone functions as a so-called remote controller.

The second system may be, for example, an in-vehicle device such as a drive recorder or a car navigation system provided in a mobile body, and may be a system on the side of transmitting information to a system that controls communication means by LPWA.

Then, when the second system periodically distributes POI data to the communication means controlled by this system, the second system does not transmit all the POI data by LPWA, but posts from the user, for example. It is preferable that only the POI data based on the above is distributed by LPWA, and the other POI data is distributed by the above-mentioned other communication means adopting a communication method (Wi-Fi or the like) other than LPWA.

Further, the second system may select and distribute only POI data satisfying a predetermined condition, such as POI data indicating the position of an automatic speed violation control device or a traffic mobilization member, by LPWA.

Further, the second power consumption suppressing means may generate a control signal indicating the trigger / trigger of the start or stop of the drive as the above-mentioned data in the controlled object of the drive recorder, the surveillance camera, the in-vehicle security system, or the like. ..

(24) The second power consumption suppressing means may be a second system that generates data indicating a determination result of determining whether or not the target device can be operated based on the access status from the system.

The amount of data received by the communication means of the system according to any one of (1) to (22) is smaller than that in the case where the communication means other than the determination result is received.

The second system may, for example, have the second transmission means transmit the determination result as a control signal of the target device. When the communication means receives a signal indicating a determination result indicating that the operation of the target device is prohibited, the target device may be controlled by the system to prevent the operation of the target device regardless of the user's operation.

The target device may be, for example, a mobile device used by a taxi or a courier company that carries luggage or a person such as a car or a motorcycle.

In this second system, the target device may access the server at the time of startup to perform the procedure so that the target device does not operate unless the authentication is passed for a certain period of time. Further, in the second system, when the server detects the theft of the target device, it is preferable not to pass the authentication.

(25) The second power consumption suppressing means may be a second system that generates data indicating a warning to a user who intends to operate the target device.

The amount of data to be transmitted is smaller than when other than the data indicating the warning is transmitted.

The operation of the target device and the target device may be as shown in (23). The second system causes the user who intends to drive the vehicle to transmit identification information such as data such as an image, a character string, and voice indicating a message indicating the prohibition of driving, or indexes thereof, to the second communication means. It is good.

(26) The second power consumption suppressing means may be a second system that causes the communication means to transmit position data indicating the position of the target device and generates the data based on the position data.

The amount of data to be transmitted is smaller than that in the case of transmitting the measurement data measured at the position of the target device for specifying the position.

The target device may be the one shown in (24). The second system may manage the position of the vehicle by storing the position data indicating the position of each vehicle received by the second communication means in a management device provided in a management center or the like.

A target device such as a drive recorder mounted on a vehicle or the like acquires position data indicating the position of its own device in the above-mentioned NMEA format by measuring with, for example, GNSS, but transmits the position data to the server in the NMEA format. Then, for example, even if the commands are narrowed down to GPMRC and GPGGA, the capacity will be large in one hour. Therefore, the system that exchanges with the second system may send only the coordinate values to the server instead of sending the raw data of NMEA, and it is particularly preferable to reduce the amount of communication by increasing the transmission interval of the coordinate values.

For example, this second system equipped with a server that manages the allocation of taxis, etc., receives a new vehicle allocation arrangement including location data indicating the location of the smartphone from the smartphone of a customer seeking a taxi, and the location is reached. It is advisable to send the next destination to the target device (drive recorder, navigation system, etc.) of a nearby vehicle to instruct the vehicle to be dispatched. In addition to the use for taxis, this second system may be applied to bus operation management operations by bus companies, pizza delivery operations, operation management operations such as transportation operations, police patrol operations by police cars, and the like.

In this system, for example, a user can check where his / her vehicle is by using a map application on a smartphone. In this system, the coordinate value indicating the position of the vehicle is not always sent, but the coordinate value is sent only when there is a request from an external device such as a smartphone or a server. This saves traffic.

(27) The second power consumption suppressing means may be a second system that generates instruction data instructing the surroundings of the target device to drive a notification device that notifies the existence of the target device. ..

In order to make the user who has lost the position of the target device find the target device, the amount of data to be transmitted is smaller than that in the case of transmitting other than the instruction data.

The target device may be, for example, a vehicle parked in a parking lot. The second system causes the second communication means to transmit instruction data, and when the communication means receives the instruction data, the system may drive a notification device that notifies the presence of the vehicle toward the surroundings of the vehicle. As the notification device, for example, a lighting device such as a headlight, a tail lamp, or a fog lamp provided in the vehicle may be used. When the notification device controls the lighting device for the purpose of notifying the presence of the vehicle toward the surroundings of the vehicle, the notification device may blink in a predetermined pattern.

In this second system, for example, when a user does not know where his / her vehicle is parked in the parking lot, when a request is made from a smartphone, a car light or a sound is emitted. In this second system, the notification device is driven instead of sending the coordinate values indicating the position of the vehicle to the smartphone. This saves traffic. By applying this second system, for example, when a mobile phone cannot be found, the user can know the position of the vehicle or the like as if he / she calls the mobile phone and makes a ringing tone.

(28) It is preferable to use the second system for transmitting the firmware for operating the system and the position data indicating one of the positions separately from the other data so that the charge is cheaper than the other data.

Compared to the case where the location data is not transmitted with the same charge system as the firmware, the charge generated by the transmission of the location data is suppressed.

Systems such as in-vehicle devices require "firmware", which is the basic software for operating themselves, and when the firmware is updated, the second system needs to send the updated firmware to each system. is there. When sending firmware, the fee structure is often set so that it is cheaper (including free) than other data. When managing the firmware update data communication, which is the communication when updating the firmware, and the normal communication with different charge systems, the second system puts the position of, for example, POI data, etc. in the firmware update data. The indicated position data may be included or attached and transmitted by LPWA in the firmware update data communication.

<Function of drive recorder>
The function of the drive recorder 1 which is an example of the first system will be described below.
The controller 11 of the drive recorder 1 functions as a "power consumption suppressing means" that controls the LPWA communication device 13 so as to suppress the power consumed.

As described above, the camera 18 captures the image of the driver's seat and outputs a video signal indicating this image, and the controller 11 converts this video signal into video data and records it on the SSD 12. The controller 11 processes this video data as "data before processing".

Specifically, the controller 11 analyzes this video data and recognizes the position and movement of each part such as the driver's neck, face, torso, and arms reflected in the video data. Then, the danger of driving by the driver is determined based on the recognized position and movement of each part of the driver.

For example, as a result of analyzing the video data, the controller 11 recognizes that the driver's neck is moving periodically according to the timing of breathing or the eyelids are closed at a rate exceeding the threshold value. Judge that the driver is dozing off. Further, when 10 seconds have passed since the driver closed his eyes, the controller 11 determines that there is a danger in driving.

When the controller 11 analyzes the above-mentioned video data to determine the danger of driving by the driver, the controller 11 generates data (judgment result data) indicating the determination result as "data after processing", and the generated determination result. The data is transmitted to the server 2 by the LPWA communication device 13.

Since this judgment result data is data showing the result of comprehensively judging the movement and position of each part of the driver by analyzing the contents of the video data and comparing it with a predetermined pattern, threshold value, etc. The amount of information is smaller than the amount of information in the video data.

Therefore, according to the above-described configuration, the power consumed when the drive recorder 1 transmits data to the server 2 is suppressed as compared with the case where the drive recorder 1 transmits the video data which is the data before processing as it is. ..

That is, the controller 11 processes the acquired acquired data so that the amount of data to be transmitted is smaller than that of the acquired data, and transmits the processed data by the LPWA communication device 13 to obtain "power consumption suppressing means". It functions as.

As described above, the controller 11 of the drive recorder 1 functions as a "power consumption suppressing means" that controls the LPWA communication device 13 so as to suppress the power consumed. Therefore, the drive recorder 1 can further suppress the power consumption in the system that controls the communication means by LPWA, which generally consumes less power than the communication by 4G or 5G.

<Modification example>
The above is the description of the embodiment, but the content of this embodiment can be modified as follows. Moreover, the following modification examples may be combined.

<Modification example 1>
The controller 11 of the drive recorder 1 described above processes the acquired data so that the amount of data is reduced and transmits the data. However, by selecting the type of data to be transmitted from the acquired data, the amount of data is transmitted. May be reduced.

That is, the controller 11 may suppress the power consumption by causing the LPWA communication device 13 to transmit a specific type of data in which the amount of data to be transmitted is smaller than that of other types of data. In this case, the drive recorder 1 does not need to process the acquired data.

For example, when the drive recorder 1 acquires two types of data, continuous time series data having a large amount of information and contact input (trigger information), the controller 11 does not select the time series data and contacts input. Only may be transmitted by LPWA. The contact input has a relatively small amount of information as compared with time series data. The drive recorder 1 suppresses power consumption in communication by not sending time-series data having a large amount of information.

In addition, the controller 11 may cause the LPWA communication device 13 to transmit identification information for identifying each data assigned to each of the plurality of data groups. Since the amount of identification information of each data is smaller than that of each data itself, the power consumed by LPWA communication is suppressed according to this configuration.

Further, when the controller 11 already has data already transmitted by a communication means different from the LPWA communication device 13 such as the short-range communication device 10, the controller 11 transmits data other than the transmitted data to the LPWA communication device 13. You may let me.

<Modification 2>
The controller 11 may suppress the power consumption by not transmitting the data indicating the video to the LPWA communication device 13.

That is, the controller 11 may select character string data, contact input data, and the like and transmit them by LPWA without selecting video data. Video data showing images and moving images (which may include audio) generally has a larger amount of data than other data showing character strings, contact inputs, judgment results, and the like. By excluding the controller 11 from the target of transmission by the LPWA communication device 13, the power consumption consumed for the communication using the LPWA communication device 13 is suppressed.

The data other than the video data may be, for example, data indicating a connection state between the drive recorder 1 and the smartphone 3 in addition to data indicating a character string, contact input, a determination result, and the like. Further, the data other than the video data may be the data received by the drive recorder 1 from the smartphone 3 when the drive recorder 1 and the smartphone 3 are connected.

The video data may be recorded on the SSD 12 and collected at a later date. Further, the video data may be sent from the smartphone 3 connected by short-range communication to the server 2 via the communication line 6.

<Modification example 3>
Even if there is data to be transmitted, the controller 11 may suppress the power consumption by not transmitting the data to the LPWA communication device 13 under a predetermined situation.

For example, the drive recorder 1 described above has a detection device for detecting a target, and when the detection device detects the target, the LPWA communication device 13 is made to transmit detection data indicating that the target has been detected. That is, when the detection device detects the target, it is when there is data to be transmitted.

On the other hand, the drive recorder 1 described above measures, for example, the position of the GNSS receiver itself, that is, the position of the drive recorder 1 including itself by the GNSS receiver 19, and specifies the current time and the position of the drive recorder 1. There is.

Then, the drive recorder 1 outputs the above-mentioned detection data to the LPWA communication device even if the detection device detects the target only when it is determined that the drive recorder 1 itself exists at a predetermined time and place. It is advisable not to let 13 transmit. That is, under the predetermined situation that the drive recorder 1 itself exists at a predetermined time and place, even if there is data to be transmitted, the data is not transmitted by the LPWA communication device 13.

<Modification example 4>
The controller 11 may suppress the power consumption by transmitting the acquired acquired data at adjusted intervals. For example, the controller 11 may transmit the position data indicating the position of the drive recorder 1 acquired from the GNSS receiver 19 to the LPWA communication device 13 at the adjusted intervals.

The adjusted interval is an interval in which the number of times the data is transmitted is less than the number of times the GNSS receiver 19 outputs the data and the controller 11 acquires the data. That is, the controller 11 adjusts the interval for transmitting the position data to the LPWA communication device 13 so as to be at least longer than the interval for the controller 11 to acquire the position data from the GNSS receiver 19. The adjusted interval does not have to be constant.

<Modification 5>
The controller 11 may transmit the acquired acquired data to the LPWA communication device 13 at intervals adjusted based on the information indicating the contract contents of the user's LPWA.

In this case, the SSD 12 stores information indicating the contract details of the user of the drive recorder 1. The controller 11 causes the LPWA communication device 13 to transmit the position data acquired from the GNSS receiver 19 at intervals adjusted based on the above-mentioned information indicating the contract contents stored in the SSD 12. As a result, for example, as compared with the case where all the position data is transmitted, the power consumption is suppressed, and the degree to which the power is suppressed depends on the contract contents of the user.

<Modification 6>
The controller 11 described above acquires and analyzes video data showing the image of the driver's seat captured by the camera 18 and stored in the SSD 12, and generates judgment result data showing the result of judging the danger of driving by the driver. Then, this was transmitted to the LPWA communication device 13.

That is, the controller 11 processes the video data into the determination result data and transmits it to the LPWA communication device 13, but the amount of data to be transmitted by the other method is smaller than that of the acquired data. It may be processed in the same manner and the processed data may be transmitted.

For example, the controller 11 may process the position data acquired from the GNSS receiver 19 so that the amount of data is small, and transmit the processed data to the LPWA communication device 13.

For example, when the position data acquired from the GNSS receiver 19 is text data generated in accordance with a standard such as NMEA 0183 regulated and managed by the National Marine Electronics Association, the controller 11 sets the controller 11. The data may be processed by extracting only some types of messages from the position data. Here, examples of some types of messages include RMC messages and GGA messages.

The processing process for processing the acquired position data so that the amount of data is reduced may be performed by a configuration other than the controller 11. For example, the controller 11 may outsource this processing to the controller 41 or the ECU 71. The controller 11 may receive the processed data generated on consignment and transmit it to the LPWA communication device 13.

Further, the danger of driving is not limited to that determined by the result of analyzing the image captured by the driver. The drive recorder 1 according to the present invention may include, for example, a device that detects the tension of a belt or rope that tightens a load of a truck in real time. The controller 11 may predict a load collapse or the like based on the detected tension and determine the danger of driving.

Moreover, the object of judgment is not limited to the danger of driving. The object of judgment may be, for example, the safety of cargo based on temperature, humidity, illuminance, etc. at the time of delivery of refrigerated goods and animals.

Further, for example, the controller 11 acquires and analyzes video data indicating a road image captured by the camera 18 and stored in the SSD 12, generates determination result data indicating the analysis result, and causes the LPWA communication device 13 to generate data. You may send it. As a result of analyzing the video data, the controller 11 may determine, for example, the presence or absence of contact, deformation, or damage of the vehicle on the road and the degree thereof.

In this case, the object of judgment is the presence or absence of a vehicle contact accident and its degree. Based on the acquired video data, the controller 11 extracts, for example, the contours of the automobile 7 and another vehicle, and specifies the respective positions in the video. Then, the controller 11 may recognize whether or not an accident has occurred by determining whether or not these vehicles are in contact with each other.

Further, the controller 11 may specify the type of the event that has occurred based on the video data, and may transmit only the identification information that identifies the type of the event to the server 2 by LPWA.

Further, when an event such as an accident occurs, the controller 11 may cause the LPWA communication device 13 to transmit information regarding the occurrence of the event in addition to the code indicating the type of the event without sending the video data. .. The information related to the occurrence of an event is the information that the measurement is started when the event occurs, the information that is extracted based on the occurrence of the event, and the information that is measured, extracted, etc. is analyzed. Information showing the result and the like can be mentioned.

For example, the controller 11 may cause the LPWA communication device 13 to transmit behavior information indicating the driver's behavior measured for 20 seconds before and after the collision accident. The behavior information includes, for example, the direction of the driver's face, the direction of the line of sight, the open / closed state of the eyelids, and the like, and the amount of data is smaller than that of the video data.

Further, the controller 11 may cause the LPWA communication device 13 to transmit information such as the acceleration detected by the acceleration sensor at the time when the collision accident occurs and the speed measured by the tachometer 74.

Further, the controller 11 may cause the LPWA communication device 13 to transmit information indicating the position of the automobile 7 positioned by GNSS or the like, vehicle behavior information indicating the behavior of the vehicle, and the like.

That is, the drive recorder 1 sends only "an accident has occurred", "the type code of the event that has occurred", and "information about the occurrence of the event" to the server 2 by LPWA together with the identification information of the drive recorder 1. Therefore, the drive recorder 1 suppresses the amount of communication as compared with the case of transmitting the video data or the audio data itself, and also suppresses the power consumption at the time of communication.

<Modification 7>
The controller 11 processes the acquired acquired data so that the amount of data to be transmitted is smaller than the acquired data, and causes the LPWA communication device 13 to transmit the processed data, and the LPWA communication device as it is. It may have a function of transmitting to 13.

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 so that the amount of data is small. Then, the controller 11 may have a function of transmitting the processed data to the LPWA communication device 13 and a function of transmitting the acquired position data to the LPWA communication device 13 as it is.

<Modification 8>
The controller 11 may process the acquired data acquired under a predetermined situation so that the amount of data is small, and transmit the processed data to the LPWA communication device 13.

Here, the determined situation may be a situation determined according to the degree of the event detected in the target device. For example, when the automobile 7 receives an impact from the outside due to a traffic accident or the like, the acceleration sensor 17 detects this impact.

Further, for example, when the automobile 7 rolls over or turns over due to an accident or the like, the acceleration sensor 17 detects the posture of the automobile 7. For example, the controller 11 processes the position data acquired from the GNSS receiver 19 according to the degree of an event such as an impact or an attitude detected in the automobile 7 so that the amount of data is small, and processes the processed data. It may be transmitted to the LPWA communication device 13. In this case, the automobile 7 is an example of the target device.

Further, when the degree of the accident is extremely large, the controller 11 may cause the LPWA communication device 13 to transmit the video data. That is, since the controller 11 does not transmit data having a large amount of data such as video data in a normal case where the degree of accident is not significantly large, compared with the case where video data is transmitted regardless of the degree of accident. Reduce the power consumption spent on communication.

Further, when the degree of the accident is larger than the threshold value, it may be clear that the automobile 7 is inoperable and no further communication is performed. In this case, since it is meaningless to leave the amount of data that can be communicated by the LPWA communication device 13, the drive recorder 1 may transmit data having a large amount of data such as video data by the LPWA communication device 13.

By transmitting the video data, the user of the server 2 can easily determine whether or not an event such as an accident has really occurred based on the video data. Then, by making it easier to determine whether or not the event has really occurred, it becomes easier to make an accurate determination of subsequent arrangements and the like.

This arrangement is, for example, calling an ambulance, calling the police, and so on. In addition, it may be found from the video data that the automobile 7 has fallen into water such as a dam. In this case, for example, the user of the server 2 can convene a diver who has undergone underwater search training as a countermeasure.

Although the acceleration sensor 17 is a sensor that measures acceleration by the MEMS method, it may be a gyro sensor that measures the rotational angular velocity of the automobile 7, or a combination thereof.

Further, when the degree of the accident is extremely large, the controller 11 may increase the amount of data transmitted to the server 2 by the LPWA communication device 13.

Further, when the degree of the accident is extremely large, the controller 11 may transmit data from the smartphone 3 connected by short-range communication to the server 2 via the communication line 6. Video data having a relatively large amount of data may be selected as the data transmitted from the smartphone 3 via the communication line 6. The smartphone 3 may be connected to the drive recorder 1 by operating the short-range communication device 30 in the background, for example. For example, the smartphone 3 has a so-called tethering function of connecting the drive recorder 1 to a communication line 6 such as the Internet by connecting the drive recorder 1 to the drive recorder 1 with the short-range communication device 30 and connecting to the communication line 6 with the communication device 37. You may have.

The smartphone 3 may have an acceleration sensor (not shown). The controller 31 of the smartphone 3 may start tethering and connect to the drive recorder 1 based on the impact detected by the acceleration sensor described above. The smartphone 3 connected to the drive recorder 1 may acquire the video data and transmit the video data to the server 2 via the communication line 6.

<Modification 9>
When one or more events detected in the automobile 7 satisfy a predetermined condition, the controller 11 may cause the LPWA communication device 13 to transmit data corresponding to the acquired acquired data.

For example, as a result of analyzing the first image captured by the driver, it is found that the driver is dozing with a probability of 70% or more, and the measured impact force exceeds a threshold value such as 5G. Suppose that the condition is satisfied. This impact force is measured by, for example, an impact force measuring device (not shown) provided in the drive recorder 1.

In this case, the controller 11 may cause the LPWA communication device 13 to transmit data corresponding to the acquired acquired data. The data corresponding to the acquired data is data showing the analysis result of the video data, data showing the behavior information of the driver, and the like.

As a result, for example, if there is a mere impact, the data will be transmitted even if the step is overcome. Data is transmitted only when it is highly likely that it has occurred.

Further, when the drive recorder 1 acquires, for example, both the detection data indicating that the automatic speed violation control device and the traffic mobilization member have been detected by the machine and the report data indicating that the user has found the data. May be transmitted. This will improve the accuracy of finding automatic speed camera and traffic mobilizers.

The drive recorder 1 according to this modification determines whether or not the conditions are satisfied for one or more detected events and determines whether or not to transmit the data. Therefore, when transmitting data focusing on only one event. In comparison, the opportunity for transmission is narrowed down, and the power consumption consumed for communication is suppressed.

<Modification example 10>
The controller 11 may process the acquired acquired data based on the information indicating the contract contents of the user's LPWA so that the amount of data to be transmitted is smaller than the acquired data, and transmit the processed data. ..

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 based on the information indicating the user's contract details (described above) stored in the SSD 12 so that the amount of data is small, and processes the processed data. It may be transmitted to the LPWA communication device 13.

For example, the user may determine the type of data to be transmitted and the conditions for transmission according to the contracted amount of communicable data per month.

<Modification 11>
The controller 11 processes the acquired acquired data according to the remaining amount of data permitted to be transmitted to the user based on the contract contents of LPWA so that the amount of data to be transmitted is smaller than the acquired data. Later data may be transmitted.

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 so as to reduce the amount of data according to the remaining amount of data permitted to be transmitted to the user based on the above-mentioned contract contents. The latter data may be transmitted to the LPWA communication device 13.

For example, if the contract is made on a monthly basis, the remaining amount of data permitted for communication is maximum at the beginning of the month, decreases according to the communication record, and becomes minimum at the end of the month. The conditions for transmitting data vary according to the fluctuation of the remaining amount of data described above. Therefore, for example, the data transmitted when the remaining amount of data is large is also transmitted when the remaining amount of data is low. It may disappear.

<Modification example 12>
The controller 11 may adjust the interval at which the LPWA communication device 13 searches for a destination for transmitting data.

The LPWA communication device 13 controlled by the controller 11 of the drive recorder 1 may have a function of searching for a transmission destination, and may further have a function of adjusting the search interval from the outside. Further, it is preferable that the controller 11 has a function of searching for a destination. Further, it is particularly preferable that both the controller 11 and the LPWA communication device 13 have a function of searching for a transmission destination.
In particular, the controller 11, which is the power consumption suppressing means of this system, may adjust the interval for searching the transmission destination of the LPWA communication device 13.

The drive recorder 1 has a means for receiving an instruction from the user, and it is preferable to forcibly restart the search for the destination when the instruction from the user is received even at the interval of searching for the destination.

<Modification example 13>
The controller 11 may adjust the time interval at which the LPWA communication device 13 stops searching for a destination for transmitting data.

The interval of the time for stopping the search for the transmission destination of the LPWA communication device 13 may be an interval between timings satisfying a predetermined condition. The controller 11 of the drive recorder 1 receives, for example, a notification from the ECU 71 of the result of monitoring the state of the engine 72 of the automobile 7. Then, when the controller 11 receives the notification that the engine 72 has stopped, it is preferable to control the stop interval of the radio wave search to be longer than when the engine 72 is started.

The controller 11 may have a function of stopping the radio wave search at the maximum time if the base station is not found in the radio wave search after the lapse of the maximum time.

After stopping the radio wave search for a predetermined time, the controller 11 sets the radio wave transmission interval to be relatively short immediately after restarting the radio wave search, and thereafter, the transmission interval is lengthened as time elapses. It is good to control it.

<Modification 14>
The controller 11 described above controls the LPWA communication device 13 and also controls the short-range communication device 10 having a communication method different from that of the LPWA communication device 13. However, when transmitting data, the controller 11 is close to the LPWA communication device 13. It is preferable to switch with the communication device 10.

This switching may be determined, for example, according to the communication state of the LPWA communication device 13 and the short-range communication device 10, the time zone, or the size of the data to be transmitted. May be done.

In the above-described embodiment, Bluetooth is adopted for the short-range communication device 10 which is an example of the "other method communication means", but as the other method communication means, 3G, LTE, 4G, 5G, Wi -Fi, DSRC, electronic toll collection system, etc. can be adopted.

Further, the short-range communication device 10 may be configured to be replaceable with the drive recorder 1. The drive recorder 1 has a function of detecting whether or not the replaceable short-range communication device 10 is available, and the controller 11 sets the LPWA communication device 13 and the short-range communication device according to the detection result. It is preferable to have a function of switching between 10.

For example, in this drive recorder 1, the LPWA communication device 13 is not connected, and the Wi-Fi module is inserted as the short-range communication device 10, and all communication including images and videos is performed by Wi. -Use the Fi module.

On the other hand, in the state where the short-range communication device 10 is not connected and the LPWA communication device 13 is plugged in, the drive recorder 1 does not communicate with the image / video and stores it in the SSD 12 which is a local storage. It is good to keep it. The drive recorder 1 may transfer the information stored in the SSD 12 by the short-range communication device 10 when the short-range communication device 10 which is a Wi-Fi module is connected, for example.

Further, for example, when both the LPWA communication device 13 and the short-range communication device 10 are plugged in, the drive recorder 1 communicates information other than images, moving images, etc. (data whose amount of data exceeds a certain amount) by LPWA. On the other hand, it is preferable to communicate the images, moving images and the like with the short-range communication device 10.

<Modification 15>
The LPWA communication device 13 of the drive recorder 1 described above may have a first communication means for communicating with the server 2 for accumulating data and a second communication means for not communicating with the server 2. In particular, the controller 11 of the drive recorder 1 may have a function of switching between the first communication means and the second communication means of the LPWA communication device 13. The first communication means for communicating with the server 2 may be, for example, SIGFOX or the like. The second communication means that does not communicate with the server 2 may be, for example, LoRa or the like. The second communication means may have a function of communicating with the server 2 via the communication line 6.

<Modification 16>
Further, the LPWA communication device 13 may have a third communication means capable of handover communication and a fourth communication means not capable of handover communication. As the handover communication, for example, communication for switching a base station that communicates with a mobile station while the mobile station is moving may be used. The third communication means capable of handover communication may be, for example, LTE-M or the like. The fourth communication means that does not enable handover communication may be, for example, LoRaWAN, SIGFOX, or the like.

<Modification 17>
The LPWA communication device 13 of the drive recorder 1 described above has a function of using a SIM that can be attached to and detached from the own machine and a function of using a SIM provided in the own machine. May not be provided. That is, the LPWA communication device 13 does not have to have the on-chip SIM 133 shown by the broken line in FIG. In this case, the LPWA communication device 13 need only use a removable SIM.

<Modification 18>
Further, the LPWA communication device 13 does not have to be provided with a removable SIM in its own device. In this case, the LPWA communication device 13 may use only the on-chip SIM 133.

<Modification 19>
The drive recorder 1 described above had a GNSS receiver 19 as a first positioning means for measuring a position. The LPWA communication device 13 has a built-in GNSS receiver 131 as a second positioning means different from the GNSS receiver 19, but the drive recorder 1 does not have to have the GNSS receiver 19. Further, the LPWA communication device 13 does not have to have the built-in GNSS receiver 131.

<Modification 20>
The controller 11 may control the user to be notified of the state of the LPWA communication device 13 from a notification means such as a display 15.

For example, the controller 11 is in use when the LPWA communication device 13 has the time when the last data was transmitted, the search state of the transmission destination, the reception strength of radio waves, and a plurality of communication means. The information indicating the time and the like may be displayed on the display 15. Further, the drive recorder 1 may notify the user of this notification by sound, LED light emission, or the like. A pictogram may be used for the display.

<Modification 21>
The LPWA communication device 13 of the drive recorder 1 may communicate with a fixed communication means that does not move. In this case, the controller 11 receives the data when the automobile 7 approaches the fixed communication means described above, and when the automobile 7 approaches the server 2 at the destination where the automobile 7 moves, the received data is transmitted by the LPWA communication device 13. It may be sent to the server 2. The fixed communication means described above is, for example, LoRa, NB that acquires measured values by measuring instruments such as a thermometer, a hygrometer, an anemometer, a rain gauge, a seismic intensity meter, and an illuminance meter, and transmits a signal indicating the measured values by LPWA. -IoT, SIGFOX, etc. are recommended.

The drive recorder 1 may be mounted on a truck, a taxi, a bus, or the like used in the transportation industry, as long as it is a moving body, or may be mounted on a motorcycle, a motorized bicycle, a bicycle, or the like. Further, the drive recorder 1 may be mounted on a railroad, a ship, an aircraft or the like used in a transportation industry such as rail transportation, ship transportation, and air transportation.

<Modification 22>
The communication line 6 may be, for example, a LAN (Local Area Network), a WAN (Wide Area Network), a combination thereof, or a combination thereof and the Internet.
Further, the communication line 6 may include a public switched telephone network (PSTN: Public Switched Telephone Networks), an integrated services digital network (ISDN), and the like.

<Modification example 23>
The drive recorder 1 and the car navigation system 4 may be wirelessly connected to each other so as to be able to communicate with each other.

<Modification 24>
In the above-described embodiment, the drive recorder 1 and the smartphone 3 are communicably connected by Bluetooth (registered trademark). For example, 3G, LTE, 4G, 5G, Wi-Fi, DSRC (Dedicated Short Range Communications) , Electronic toll collection system (ETC) or other communication means (other communication means) different from LPWA may be used for connection.

<Modification 25>
The LPWA communication device 13 described above is a communication device conforming to the LPWA method for performing relatively long-distance communication with low power consumption, in addition to the above-mentioned "ELTRES", "LoRa", "LoRaWAN", and "LTE-MTC". "NB-IoT""NB-FiProtocol""RPMA""GreenOFDM""DASH7""RPMA""Wi-SUN""EnOcean Long Range""Weightless-P""SIGFOX""LTECat.0""LTE It may be "Cat.M1" or the like.

<Modification 26>
The drive recorder 1 may have an insertion slot for inserting a removable medium such as an SD card for permanently storing data in place of or in addition to the SSD 12.

<Modification 27>
The video signal output from the camera 18 was recorded on the SSD 12, but may be recorded on a removable medium such as an SD card. Further, the video data converted from the video signal may be sent to the server 2 when the drive recorder 1 and the server 2 are connected by a method other than LPWA such as LTE or Wi-fi. In this case, the drive recorder 1 may send the video data to the server 2 via the smartphone 3. The controller 11 of the drive recorder 1 may monitor the state of the camera 18 and send information indicating this state to the server 2 by LPWA. The state of the camera 18 is information such as temperature, exposure amount, whether or not the camera 18 is moving, and whether or not it is normal.

<Modification 28>
The short-range communication device 10 described above communicated using Bluetooth (registered trademark). That is, the above-mentioned short-range communication device 10 is a communication means based on IEEE802.5.1, but other standards such as a wireless LAN system (IEEE802.11) and an ultra-wideband wireless system (IEEE802.1.3a). ), ZigBee (IEEE802.154), near field communication (ISO / IEC 10536, ISO / IEC 14443, ISO / IEC 15693, ISO / IEC 18092, ISO / IEC 21481, etc. and combinations thereof). It may be a device.

<Modification 29>
The car navigation system 4 may have an insertion slot for inserting a removable medium such as an SD card for permanently storing data in place of or in addition to the SSD 42.

<Modification 30>
The controller 11 of the drive recorder 1 described above functions as a "power consumption suppressing means" that controls the LPWA communication device 13 so as to suppress the power consumption so as to exchange information with the server 2. In addition to or instead, the controller 21 of the server 2 suppresses the power consumed by the LPWA communication device 13 when the LPWA communication device 13 receives the data transmitted from the server 2 side to the drive recorder 1 side. It may function as a "second power consumption suppressing means" for generating this data.

In this case, the server 2 is a second system on the side of transmitting information to the drive recorder 1. The controller 21 may use a method equivalent to the method for the controller 11 of the drive recorder 1 described above to function as the power consumption suppressing means.

<Modification 31>
The system in the present invention is not limited to the drive recorder 1 as a monitoring system for a vehicle, and may be another device or the like. For example, the system in the present invention may be a monitoring system for a vending machine, a monitoring system for a gas meter, a water meter, or the like, instead of the drive recorder 1.

Further, for example, the system in the present invention may be a house monitoring system for monitoring a house. This home surveillance system takes a picture of the door with a camera and analyzes the image with a controller to determine if the door has opened. In addition, the controller of this house monitoring system analyzes the above-mentioned image to determine whether or not the person who entered through the open door is a pre-registered family member. Then, the house monitoring system may transmit these determination results to the server 2 by LPWA.

The server 2 may comprehensively judge these judgment results and send the judgment result to the housing monitoring system by LPWA, such as "the risk of a thief is 70%". Communication from the housing monitoring system to the server 2 and communication from the server 2 to the housing monitoring system are performed by LPWA, and the data acquired by each is not sent as it is, but processed and the type is selected. Therefore, the power consumption required for communication is suppressed.

<Modification 32>
The controller 21 of the server 2 may generate data indicating a determination result of determining whether or not the target device can be operated based on the access status from the drive recorder 1.

For example, when the drive recorder 1 analyzes the video data and determines the danger of driving, the drive recorder 1 transmits the determination result data indicating the determination result to the server 2 by the LPWA communication device 13. The server 2 may cause the LPWA communication device 23 to transmit a control signal of the automobile 7 according to the acquired determination result data.

For example, when the driving risk exceeds the threshold value, the server 2 may transmit a control signal prohibiting the driving of the automobile 7 to the drive recorder 1 by the LPWA communication device 23. When the drive recorder 1 receives the control signal prohibiting this operation from the server 2 by the LPWA communication device 13, for example, the drive recorder 1 may transmit this control signal to the ECU 71 of the automobile 7 via the car navigation system 4 described above.

Upon receiving the control signal prohibiting driving, the ECU 71 of the automobile 7 may control the engine 72 and the transmission 73 to control each part of the automobile 7 so as to prevent the driving of the automobile 7 regardless of the user's operation.

The drive recorder 1 may access the server 2 at startup to perform the procedure, and instruct the ECU 71 not to operate the automobile 7 when the authentication does not pass for a certain period of time. Further, when the server 2 detects the theft of the automobile 7, it is preferable not to pass the authentication.

The automobile 7 may be an automobile used by a taxi, a courier, or the like, or may be another moving body such as a motorcycle, a motorized bicycle, or a bicycle that carries luggage or a person.

Further, when the determined driving risk does not exceed the threshold value, the drive recorder 1 may record the content of the determination or the information used for the determination in the SSD 12. This record may be used by the user as a so-called life log. That is, by recording the content of the judgment of the danger of driving or the information used for the judgment in the drive recorder 1, the user can reflect on the content of the driving, grasp the tendency of his / her own driving, and normalize. You can increase your motivation to drive well.

<Modification 33>
The controller 21 of the server 2 may generate data indicating a warning to a user who intends to operate the target device.

For example, the control signal for prohibiting driving of the automobile 7 transmitted by the server 2 to the drive recorder 1 may include data instructing the user who intends to drive the automobile 7 to warn. When the controller 11 of the drive recorder 1 receives this control signal, it may control the driving of the automobile 7 and display a warning to a person who intends to drive the automobile 7 on the display 15.

<Modification 34>
The controller 21 of the server 2 may cause the communication means to transmit position data indicating the position of the target device, and generate the data based on the position data.

For example, when managing taxi dispatch, the server 2 receives a new vehicle dispatch arrangement including location data indicating the location of the smartphone 3 from the smartphone 3 of the customer seeking a taxi. Then, the server 2 may transmit the next destination to the drive recorder 1 of the automobile 7 or the car navigation system 4 near the location indicated by the location data to instruct the vehicle allocation.

Further, when the server 2 receives a request for position information indicating the position of the automobile 7 from the user's smartphone 3, the server 2 may send this request to the drive recorder 1 by the LPWA communication device 23. The LPWA communication device 13 of the drive recorder 1 may receive this request from the server 2 and send the position information indicating the position of the own device measured by the GNSS receiver 19 to the server 2 by the LPWA communication device 13.

The server 2 sends the location information acquired from the drive recorder 1 to the smartphone 3 via the communication device 27 and the communication line 6. Then, the smartphone 3 may display the position of the drive recorder 1, that is, the position of the automobile 7 equipped with the drive recorder 1 on the display 35 based on the sent position information.

As a result, the user can confirm where his / her car 7 is by using the map application of the smartphone 3. In this system, the drive recorder 1 does not always send the coordinate value indicating the position of the automobile 7, but sends the coordinate value only when there is a request from an external device such as a smartphone 3 or a server 2, so that the amount of communication is saved. And the power consumption for communication is suppressed.

<Modification 35>
The controller 21 of the server 2 may generate instruction data instructing the surroundings of the target device to drive the notification device that notifies the existence of the target device.

For example, when the controller 11 of the drive recorder 1 receives this instruction data from the server 2, it communicates with the ECU 71 of the automobile 7 via the car navigation system 4. Then, the controller 11 may instruct the ECU 71 of the automobile 7 to drive the lamp 75 so as to notify the existence of the automobile 7 in response to the instruction data. In this case, the automobile 7 is an example of the target device, and the lamp 75 is an example of the notification device.

<Modification 36>
The controller 21 of the server 2 controls the LPWA communication device 23 and supplies the firmware for operating the drive recorder 1 and the position data indicating one of the positions so that the charge is cheaper than the other data. It may be transmitted separately from the data of.

<Modification 37>
