Description

  The present invention relates to a vehicle drive recorder, an operation recording system, and an operation recording control method, and more particularly to a technique for associating recorded data with a driver.

  For example, a vehicular drive recorder developed on the assumption that it is installed in a car is equipped with an in-vehicle camera, and generally images the situation in a short time zone including when an abnormality such as a traffic accident occurs. Automatically record and save as information. The presence or absence of an abnormality such as a traffic accident can be automatically identified by using an acceleration sensor or the like. In the case of a drive recorder equipped with a large-capacity storage device, images taken by the in-vehicle camera may be continuously recorded continuously. In this case, when an abnormality occurs, information on a mark (flag) indicating the occurrence of the abnormality is recorded together with the image.

  Such a drive recorder can reliably record the situation at the timing before and after that point as an image when a dangerous situation occurs while driving a car or when a traffic accident actually occurs. it can. Therefore, the information recorded by the drive recorder can be used as evidence when investigating the situation of an accident, or can be used for management and analysis of safe driving.

  By the way, in the case of a private car, for example, the driver of the vehicle is often a predetermined owner or a family member. Therefore, it is possible to easily identify the driver corresponding to the driving situation represented by the information recorded by the drive recorder mounted on the vehicle.

  On the other hand, in the case of commercial vehicles such as taxis, buses, trucks, and rental cars, the owner of each vehicle is often a company. In many cases, an unspecified number of drivers use a common vehicle alternately. Therefore, it is difficult to specify the driver corresponding to the driving situation represented by the information recorded by the drive recorder mounted on each vehicle.

  Therefore, when a problem such as a traffic accident is detected in a company that manages the vehicle, the situation of the accident can be analyzed based on the information recorded by the drive recorder. Unable to identify the driver.

  A technique for associating information recorded by the drive recorder with a specific driver is disclosed in Patent Document 1, for example. Patent Document 1 proposes that information for specifying a driver is automatically acquired by reading the contents of an IC card or a license and recorded on a recording medium.

  Information recorded by the vehicle drive recorder is generally recorded on a removable recording medium such as a memory card. Therefore, a large number of recording media are prepared in advance, one recording medium is distributed to each of a large number of drivers, and the driver is identified on each recording medium as in the contents of the IC card of Patent Document 1. It is also possible to register possible information in advance. That is, if each driver starts operating a specific recording medium distributed to himself / herself to the drive recorder, the information recorded on each recording medium can be associated with the driver. it can.

  However, it is extremely difficult for each driver to repeat a daily operation of attaching a recording medium to the drive recorder before starting the operation and removing the recording medium from the drive recorder and bringing it home when the operation is finished. Annoying. Therefore, there is a high possibility that each driver forgets to attach the recording medium to the drive recorder before starting the operation or forgets to remove the recording medium from the drive recorder when the operation is finished. As a result, it is considered that a situation where the information recorded on the recording medium and the actual driver do not match is likely to occur.

  The information recorded by the drive recorder is generally not used unless a special problem such as a traffic accident occurs. Therefore, in order to correctly record information that is used infrequently in this manner, it is very troublesome for the driver to attach or remove the recording medium to / from the drive recorder at the start / end of driving. . Also, as disclosed in Patent Document 1, it is similarly troublesome to make the drive recorder read the license information each time the vehicle is driven.

A plurality of in-vehicle cameras 131 may be connected to the drive recorder main body 110. In that case, the plurality of in-vehicle cameras 131 are arranged so as to capture images in different directions.

  The acceleration sensor 132 outputs an electrical signal indicating the magnitude of acceleration applied to the vehicle. This signal is used to identify whether or not an abnormal condition such as a traffic accident has occurred. The acceleration sensor 132 may be built in the drive recorder main body 110.

  The vehicle speed sensor 133 outputs a vehicle speed pulse signal that can be used for detecting the moving speed (vehicle speed) of the vehicle. That is, every time the wheel rotates by a predetermined amount and the vehicle moves by a predetermined amount, one pulse signal appears as a vehicle speed pulse signal. The vehicle speed can be calculated based on the generation period of the vehicle speed pulse signal.

  The microcomputer 111 implements a predetermined function for operating as a drive recorder by executing a program previously stored in an internal memory. Thereby, for example, the operation of the drive recorder 100 as shown in FIG. 1 is realized.

  The memory 115 is used to write and read data that is temporarily used. The memory 115 is also used as a buffer memory for temporarily storing the latest image data obtained by photographing with the in-vehicle camera 131 for a predetermined time (for example, 10 seconds).

  The communication interface 116 is an interface for enabling data communication between the drive recorder 100 and the operation recording device 200.

  The recording medium 120 is provided for storing data recorded by the drive recorder 100. As a realistic recording medium 120, it is assumed that a memory card incorporating a nonvolatile memory is used. The recording medium 120 is detachable from the drive recorder 100.

  That is, when the data recorded by the drive recorder 100 is to be analyzed, only the data recorded by removing the recording medium 120 from the drive recorder 100 can be acquired. In the present embodiment, as will be described later, since a crew member code representing each driver is automatically added to data recorded on the recording medium 120, the recording medium 120 is replaced when the driver changes. There is no need.

  2 includes a microcomputer (CPU) 201, interfaces 202 to 208, a power supply unit 209, a nonvolatile memory 211, a volatile memory 212, a recording medium interface 213, an audio interface 214, a clock circuit ( RTC) 215, read only memory (EEPROM) 216, switch input unit 217, display controller 218, and communication interface 219.

  The microcomputer 201 implements a function as the operation recording device 200 by executing a program stored in advance on the read-only memory 216. With this function, the operation of the operation recording apparatus 200 as shown in FIG. 1 is also realized.

  The interface 202 is provided for inputting and processing an electric signal representing the vehicle speed, an electric signal representing the engine speed, and the like. The interface 203 is provided for outputting an alarm signal relating to an abnormality in the vehicle speed or an abnormality in the engine speed.

  The interface 204 is used for inputting a signal from a predetermined external device, and the interface 206 is used for outputting a signal to the predetermined external device. The interface 205 is used for inputting an analog electric signal.

  The interface 207 is provided for connecting a predetermined GPS device that receives a radio wave from a GPS (Global Positioning System) satellite and calculates the position of the vehicle. The interface 208 is provided for connecting a predetermined communication terminal.

  The non-volatile memory 211 is used to store data (such as constants) that need to be retained even when the power supply of the operation recording apparatus 200 is interrupted. The volatile memory 212 is used to write or read temporarily used data as necessary.

  The recording medium interface 213 physically holds a detachable recording medium 220 and is used for writing and reading data on the recording medium 220. The recording medium 220 is a detachable memory with a built-in nonvolatile memory such as a memory card. In the present embodiment, a plurality of recording media 220 are prepared in advance, and each recording medium 220 has a crew code individually assigned to a specific crew member using the recording media 220, that is, identification for distinguishing a plurality of crew members. Information is registered in advance.

  The voice interface 214 is used for converting sound such as voice into data and inputting it. The clock circuit 215 can generate information regarding the current date and time. The switch input unit 217 is provided for accepting an input by a driver's predetermined switch operation. For example, a signal that changes according to the operation of the “recording end button” is input to the switch input unit 217.

  The display controller 218 is provided to display information related to the operation state of the operation recording device 200 on a predetermined liquid crystal display (LCD). The communication interface 219 has a function for enabling data communication between the operation recording device 200 and the drive recorder 100.

  The main operations of the drive recorder 100 and the operation recording apparatus 200 shown in FIG. 2 are shown in FIG. First, operation | movement of the operation recording apparatus 200 shown in FIG. 1 is demonstrated. When the operation recording apparatus 200 is turned on, the microcomputer 201 executes predetermined initialization in step S11 of FIG. 1 and then proceeds to step S12.

  In step S12, the microcomputer 201 monitors the state of the recording medium interface 213, identifies whether or not the recording medium 220 is attached to the recording medium interface 213, and after detecting that it has been attached, proceeds to the next step S13. move on.

  In step S <b> 13, the microcomputer 201 starts the recording operation of the operation recording device 200. For example, vehicle speed and engine speed information input from the interface 202 is collected at regular time intervals, and the information is recorded on the recording medium 220 as operation information together with information on the current date and time acquired from the clock circuit 215. This recording operation is continued until the “recording end button” is pressed.

  In step S14, the microcomputer 201 reads out and acquires the crew member code held at the predetermined location from the recording medium 220 currently mounted on the recording medium interface 213, and records that the crew member code has started recording. Along with the start code, it is transmitted to the drive recorder 100 via the communication interface 219.

  In step S15, the microcomputer 201 monitors the state of the switch input unit 217 to identify whether or not the “recording end button” has been pressed. If the “recording end button” has not been pressed, the operation information recording operation started in step S13 is continued. If the “recording end button” has been pressed, the operation proceeds to step S16 to end the operation information recording operation.

  In step S <b> 17, the microcomputer 201 transmits the crew member code acquired in step S <b> 14 to the drive recorder 100 via the communication interface 219 together with a recording end code indicating that recording has ended.

  Next, the operation of the drive recorder 100 shown in FIG. 1 will be described. When the power of the drive recorder 100 is turned on, the microcomputer 111 executes predetermined initialization in step S21 in FIG. 1 and then proceeds to step S22.

  In step S22, the microcomputer 111 monitors the state of a predetermined input port to which the recording medium 120 is connected, identifies whether the recording medium 120 is connected to the drive recorder main body 110, and enters the connected state. Proceed to the next Step S23.

  In step S23, the microcomputer 111 starts a predetermined recording operation for operating as the drive recorder 100. For example, the magnitude of the acceleration output from the acceleration sensor 132 is constantly monitored, and when the acceleration exceeds a predetermined threshold, it is used as a trigger for image data, acceleration data, and vehicle speed data for a predetermined time (for example, 10 seconds). Only time series data is recorded on the recording medium 120. It should be noted that the latest image data for a predetermined time (for example, 10 seconds) is constantly recorded in the buffer memory so that data before the time when the trigger is generated can also be recorded on the recording medium 120.

  In step S24, the microcomputer 111 identifies whether or not the communication interface 116 has received the crew member code data from the operation recording device 200. If received, the microcomputer 111 proceeds to step S25. If not received, the microcomputer 111 proceeds to step S28. .

  In step S25, the microcomputer 111 identifies whether the data received by the communication interface 116 together with the crew member code data from the operation recording device 200 is the “recording start code”. If the data is “recording start code”, the microcomputer 111 proceeds to step S26. If “recording end code”, the process proceeds to step S27.

  In step S26, the microcomputer 111 considers that the new crew member has started the operation of the vehicle, and stores the crew member code received in step S24 and the operation start code indicating the start of operation in the recording medium 220. Record. About the position on the recording medium 220 which records a crew member code and an operation start code by step S26, it is set as the area | region which plans to record image data from now on, or the folder showing it. Moreover, you may record the information of the present date and time with a crew member code and an operation start code.

  In step S27, the microcomputer 111 considers that the current crew member has finished the operation of the vehicle, and stores the crew member code received in step S24 and the operation end code indicating that the operation has ended in the recording medium 220. Record. The position on the recording medium 220 where the crew member code and the operation end code are recorded in step S27 is the area where the last image data or the like is recorded or the folder representing it. Moreover, you may record the information of the present date and time with a crew member code and an operation end code.

  In step S28, the microcomputer 111 monitors the state of a “recording end button” (not shown) connected to the drive recorder 100. If this “recording end button” is pressed, the microcomputer 111 proceeds to step S30 and is pressed. If not, the process proceeds to step S29.

  In step S29, if the recording period is within a predetermined time from the occurrence of the trigger, the image data obtained by photographing with the in-vehicle camera 131 is recorded in the recording medium 120 as time series data.

  In step S30, the microcomputer 111 ends the recording operation started in step S23.

  Therefore, for example, when the drive recorder 100 and the operation recording device 200 are mounted on a business vehicle such as a taxi, a bus, or a truck in which a plurality of crew members perform driving operations in turn, one recording medium for the drive recorder 100 If 120 is left attached, data such as images relating to the driving conditions of a plurality of crew members will be recorded on the common recording medium 120. However, since the control as shown in FIG. 1 is performed, it is possible to distinguish which crew member each of the plurality of data recorded on the recording medium 120 corresponds to.

A specific change in the situation of the drive recorder 100 and the operation recording apparatus 200 will be described with reference to an example shown in FIG.
As shown in FIG. 3, when the crew member A starts to ride on a certain vehicle at time t1, the crew member A uses the recording medium 220A distributed in advance to the recording medium 220 of the operation recording device 200 mounted on the vehicle. The interface 213 is loaded. This is an operation that each crew member should perform daily. At this time, if the recording medium 120 is not attached to the drive recorder 100, the crew member A loads the recording medium 120 prepared in advance into the drive recorder 100, for example.

  When the operation recording apparatus 200 detects that the recording medium 220A has been loaded after the time t1, the operation recording apparatus 200 executes step S14 of FIG. 1, so that the crew code registered in the recording medium 220A (identification information assigned to the crew A) ) And a recording start code are transmitted to the drive recorder 100.

  When the drive recorder 100 receives the crew member code and the recording start code from the operation recording device 200, the drive recorder 100 executes steps S24, S25, and S26 of FIG. 1, and therefore the received crew member code and operation start code (when the current date and time information is included). Is recorded in an area (for example, the head position) where image data is to be recorded from now on the recording medium 120.

  When a trigger is generated due to detection of an abnormally large acceleration or the like, the drive recorder 100 records data such as a captured image on the recording medium 120 as a trigger. Data such as images to be recorded here is associated with the crew member code and the operation start code.

  When the crew member A intends to finish the operation of the day (time t2), as a daily operation, after pressing the “record end button” of the operation recording device 200, data relating to his own operation record is recorded. The recording medium 220A is removed from the operation recording device 200 and brought back. Since the operation recording device 200 executes step S17 of FIG. 1 when the “recording end button” is pressed, the crew member code and the recording end code acquired from the recording medium 220A are transmitted to the drive recorder 100.

  When the drive recorder 100 receives the crew member code and the recording end code from the operation recording device 200, the drive recorder 100 executes steps S24, S25, and S27 of FIG. Is recorded in an area on the recording medium 120 where image data is recorded (for example, the last position of the image data).

  Further, when the crew member B starts to crew from another time t3 with respect to the same vehicle as described above, the crew member B uses the recording medium 220B distributed in advance to himself / herself as the recording medium of the operation recording device 200 mounted on the vehicle. The interface 213 is loaded.

  As a result, as in the case of time t1, the operation recording apparatus 200 executes step S14 in FIG. 1, and displays the crew member code (identification information assigned to the crew member B) and the recording start code registered in the recording medium 220B. It transmits to the drive recorder 100.

  When the drive recorder 100 receives the crew member code and the recording start code from the operation recording apparatus 200, the drive recorder 100 executes steps S24, S25, and S26 of FIG. 1, so that the received crew member code and operation start code of the crew member B are stored on the recording medium 120. The image data is recorded in an area (for example, the head position) where image data is to be recorded.

  When the crew member B intends to end the operation of the day (time t4), as a daily operation, after pressing the “record end button” of the operation recording device 200, data relating to his own operation record is recorded. The recording medium 220B is removed from the operation recording device 200 and brought back. Since the operation recording device 200 executes step S17 of FIG. 1 when the “recording end button” is pressed, the crew member code and the recording end code acquired from the recording medium 220B are transmitted to the drive recorder 100.

  When the drive recorder 100 receives the crew member code and the recording end code from the operation recording device 200, the drive recorder 100 executes steps S24, S25, and S27 of FIG. Is recorded in the area (for example, the last position of the image data) on the recording medium 120 where the image data is recorded.

  Accordingly, the data such as images recorded on the recording medium 120 mounted on the drive recorder 100 is associated with a crew member code representing the corresponding crew member at each start of operation and end of operation of each crew member. In other words, when a plurality of crew members use a common vehicle in turn to perform operation work, each recorded data and each crew member's information can be recorded without replacing the recording medium 120 mounted on the drive recorder 100 for each crew member. It can be associated with the operation section.

  As described above, the vehicle drive recorder, the operation recording system, and the operation recording control method according to the present invention perform operation operations by using a single commercial vehicle such as a taxi, a bus, and a truck, for example, in turn. It can be assumed to be used in such cases. Then, the data recorded by the drive recorder can be associated with each crew member without the crew member performing a special operation such as replacing the recording medium to be mounted on the vehicle drive recorder when the crew member changes. Therefore, an operation error (for example, forgetting to attach the recording medium) of the crew is less likely to occur, and the information recorded by the drive recorder can be managed correctly. Note that the operation of mounting an independent recording medium or the like for each crew member on the operation recording device is an operation that is indispensable for daily work, and therefore, operation mistakes are unlikely to occur.
