Description

  The present invention relates to a vehicle moving image transmission system and a vehicle moving image transmission method.

  2. Description of the Related Art Conventionally, a digital tachograph equipped with a camera stores moving image data of images taken at regular intervals in a recording medium such as an SD card, in addition to vehicle driving data. The digital tachograph also stores a search list in which the moving image data stored in the recording medium and the shooting date / time are associated with each other. There is also a digital tachograph that can transmit moving image data and a search list stored in a recording medium by wireless communication in response to an acquisition request from an office PC or the like.

  In a bus company as a business operator, when there is a complaint from a user, it is required to check the recorded video as a countermeasure. At that time, the digital tachograph transmits moving image data and a search list to an office PC such as a head office or a sales office corresponding to the complaint.

  For example, a digital tachograph with a drive recorder function that records the operation status of a vehicle disclosed in Patent Document 1 can be communicated with an office PC operated by an operation manager who manages the operation of the vehicle. In order to make a call to the driver on board the vehicle, the driver's video and the driver's voice are acquired as information on the driver through the in-vehicle camera / microphone and transmitted to the office PC. Yes.

  Operation | movement of the vehicle moving image transmission system 5 which has the said structure is shown. For example, it is assumed that a complaint from a bus passenger that “a problem has occurred in the bus around 5 o'clock” enters the sales office 60B. The manager of the client 30 of the sales office 60B specifies the bus for which the complaint has been made based on information from the passenger. The client 30 uses the identified vehicle identification information as follows.

  FIG. 5 is a flowchart showing a search list request procedure by the client 30. First, the CPU 31 of the client 30 displays the specified vehicle driving situation screen G01 (see FIG. 2) on the display unit 33 (step S1). The CPU 31 determines whether or not the moving image request button bt1 arranged on the driving situation screen G01 has been pressed by the user and a search list acquisition request has been made (step S2). When there is no search list acquisition request by a user operation, the CPU 31 repeats the process of step S2.

  On the other hand, when there is a search list acquisition request by a user operation, the CPU 31 transmits a search list acquisition request to the server 50 (step S3). CPU 31 waits until reception of the search list from server 50 is completed (step S4).

  When the reception of the search list is completed, the CPU 31 displays the search list screen G02 on the display unit 33 (step S5). At this time, map information is also displayed. When the user presses the list list request button bt2 on the search list screen G02, the search list SLT displayed on the search list screen G02 can be updated. The CPU 31 determines whether or not any record registered in the search list has been selected by the user on the search list screen G02 (step S6). If not selected, the CPU 31 repeats the process of step S6. On the other hand, when any record is selected, the CPU 31 determines whether the selected record is plural or individual (step S7). When a plurality of records are selected, the CPU 31 acquires a plurality of 60-second moving image data records registered in the search list SLT, displays a map corresponding to these moving image data on the display unit 33, and displays each image. A plurality of vehicle positions at the time are displayed as points Pt (see FIG. 3) on the map (step S8). On the other hand, when one record is selected, that is, when an individual record is selected, the CPU 31 acquires a record of individual 60-second moving image data registered in the search list SLT, and a map corresponding to this moving image data. Is displayed on the display unit 33, and the position of the vehicle is displayed as a point Pt (see FIG. 3) on the map (step S9). After the processes in steps S8 and S9, the CPU 31 ends this process.

  FIG. 6 is a flowchart showing a search list transmission procedure by the server 50. The CPU 51 of the server 50 determines whether a search list acquisition request has been received (step S11). When the search list acquisition request has not been received, the CPU 51 repeats the process of step S11. On the other hand, when the search list acquisition request is received, the CPU 51 determines whether or not the vehicle search list based on the received search list acquisition request is stored in the storage 55 (step S12). If the search list has been stored, the CPU 51 reads the search list SLT stored in the storage 55 (step S13), and returns (transmits) the read search list SLT to the client 30 (step S14). Thereafter, the CPU 51 ends this process.

  On the other hand, if the search list is not stored in the storage 55 in step S12, the CPU 51 communicates with the digital tachograph 10 to obtain the search list SLT stored in the memory card 65 of the digital tachograph 10 (step S15). This search list SLT is stored in the storage 55 (step S16). Further, the CPU 51 transmits the search list SLT to the client 30 in step S14. Thereafter, the CPU 51 ends this process.

  FIG. 7 is a flowchart showing a moving image request procedure by the client 30. This moving image request process is a process performed subsequent to the search list request process of FIG. That is, in the search list screen G02 displayed on the display unit 33, a specific record is selected by the user.

  The CPU 31 determines whether or not the moving image request button bt3 is pressed by the user for the record selected on the search list screen G02 and there is a request for acquisition of moving image data for 60 seconds (step S21). When there is no request for acquisition of 60-second moving image data by a user operation, the CPU 31 repeats the process of step S21.

  On the other hand, when there is a request for acquiring 60-second moving image data by a user operation, the CPU 31 determines whether or not the 60-second moving image data at the same time is stored in the moving image storage unit 46 (step S22). When the 60-second moving image data is stored in the moving image storage unit 46, the CPU 31 proceeds to the process of step S26. On the other hand, when the 60-second moving image data at the same time is not stored in the moving image storage unit 46, the CPU 31 requests the server 50 to acquire 60-second moving image data (step S23). The CPU 31 waits until reception of 60-second moving image data from the server 50 is completed (step S24). Usually, it takes about several minutes to complete the reception of 60-second moving image data.

  When the reception of the 60-second moving image data is completed, the CPU 31 stores the 60-second moving image data in the moving image storage unit 46 (step S25). Further, the CPU 31 displays a preview screen (see FIG. 4) of 60-second moving image data on the display unit 33 (step S26). In this case, when the video request button bt3 is pressed and there is no 60-second video data at the same time, a preview screen is displayed when the received 60-second video data is saved. If there is data, the 60-second moving image data stored in the moving image storage unit 46 is read and a preview screen is displayed. Further, not only when requesting a moving image, the preview screen G03 can be displayed at an arbitrary timing by the user pressing the preview button bt4.

  The CPU 31 determines whether the selected record is individual or plural (step S27). If there are a plurality of selected records, the CPU 31 determines whether or not the record corresponding to the 60-second moving image data displayed on the preview screen G03 is the last record (step S28). If it is not the last record, the CPU 31 returns to the process of step S23. On the other hand, if it is the last record in step S28 or if it is determined as individual in step S27, the CPU 31 determines whether or not the “close” button bt5 is pressed in the search list screen G02 (step S29).

  If the “close” button bt5 is not pressed, the CPU 31 returns to the process of step S21. On the other hand, when the “close” button bt5 is pressed, the CPU 31 deletes the search list screen G02 and ends this operation.

  FIG. 8 is a flowchart showing a moving image transmission procedure by the server 50. This moving image transmission process is a process performed subsequent to the search list transmission process of FIG. That is, on the search list screen G02 displayed on the display unit 33, the video request button bt3 is waiting to be pressed by the user.

  The CPU 51 of the server 50 determines whether or not a 60-second moving image data acquisition request has been received (step S31). When the 60-second moving image data acquisition request has not been received, the CPU 51 repeats the process of step S31. On the other hand, when receiving the 60-second moving image data acquisition request, the CPU 51 determines whether or not 60-second moving image data based on the received 60-second moving image data acquisition request is stored in the storage 55 (step S32). When the 60-second moving image data has been stored, the CPU 51 reads the 60-second moving image data MV stored in the storage 55 (step S33), and returns (transmits) the read 60-second moving image data MV to the client 30 ( Step S34). Thereafter, the CPU 51 ends this process.

  On the other hand, when the 60-second moving image data is not stored in the storage 55 in step S32, the CPU 51 communicates with the digital tachograph 10, and the 60-second moving image data stored in the memory card 65 or the recording unit 17 of the digital tachograph 10 is stored. The 60-second moving image data is acquired (step S35) and stored (stored) in the storage 55 (step S36). Furthermore, CPU51 transmits this 60 second moving image data to the client 30 in step S34. Thereafter, the CPU 51 ends this process.

  The vehicle moving image transmission system 5 of this embodiment has a configuration including a digital tachograph 10, a server 50, and a client 30. The digital tachograph 10 shoots at least one of the vicinity of the vehicle and the inside of the vehicle and generates moving image data every predetermined time length (for example, 60 seconds), 60-second moving image data generated by the camera 23 and its shooting time. And a memory card 65 capable of storing 60-second moving image data and the search list SLT. The server 50 has a storage 55 and acquires 60-second moving image data and a search list SLT from the digital tachograph 10. The client 30 makes a transmission request for the search list SLT and a transmission request for 60-second moving image data included in the received search list SLT to the server 50.

  When there is a request for transmitting the search list SLT and 60-second moving image data from the client 30, the server 50 acquires the search list SLT and 60-second moving image data from the digital tachograph 10 by wireless communication and transmits the data to the client 30. At the same time, it is stored in the storage 55. When the search list SLT and 60-second moving image data requested to be transmitted from the client 30 are stored in the storage 55, the server 50 stores the search list SLT and 60-second moving image data stored in the storage 55 in the client 30. Send to.

  Thereby, when there is an acquisition request of the moving image data of the video imaged by the vehicle from the client, the moving image data can be transmitted promptly. Therefore, it is possible to shorten the time until the client reproduces the video based on the moving image data. For example, even when there is a request for acquiring 60-second moving image data from a plurality of clients 30 at a base such as a head office or a sales office at the same time, the server 50 can smoothly respond to these acquisition requests. Therefore, one client can access the digital tachograph, but another client cannot access it, and communication with the digital tachograph is interrupted due to a timeout, so that it is not possible to acquire 60-second moving image data.

  In addition, when a client receives 60-second moving image data, but the object of the complaint is not reflected in the 60-second moving image data, a request for acquiring 60-second moving image data is repeated many times, so that another client is notified. It is possible to avoid delaying the distribution of the 60-second moving image data. Therefore, the user of another client does not have to wait for a long time, and the operability is improved.

  Further, since it is not necessary to transmit the same 60-second moving image data from a digital tachograph to a plurality of clients, there is no waste of communication, and the communication cost and the load on the digital tachograph can be reduced. Further, when moving image data is stored in the storage, it is not necessary to transmit the digital tachograph, so that the time until the client 30 displays the preview screen can be shortened.

  The client 30 also has a display unit 33. The display unit 33 displays a search list screen G02. Further, when the user of the client 30 selects any 60-second moving image data included in the search list SLT, the display unit 33 displays a map including a location associated with the 60-second moving image data on the search list screen G02. To display.

  In this way, since the vehicle equipped with the digital tachograph at the imaging time is displayed on the map, it is easy for the user (client administrator) to find the 60-second moving image data being searched from the position of the vehicle on the map, The 60-second moving image data can be searched early. Accordingly, it is possible to increase the probability (hit rate) of searching for desired 60-second moving image data from among many 60-second moving image data, and the operability is improved. Further, the time required for the search operation can be shortened, and for example, it is not necessary to wait for a long time for a user who reports a complaint at the complaint processing center.

  When the server 50 acquires the search list SLT and 60-second moving image data from the digital tachograph 10, the search list SLT and the 60-second moving image data already stored in the storage 55 are stored in the search list SLT and the 60-second moving image data. Overwrite to.

  Thus, since the server 50 stores only the latest search list SLT and 60-second moving image data in the storage 55, the search list and 60-second moving image data received from the digital tachograph mounted on many vehicles are stored. Even so, the memory capacity of the storage does not have to be consumed more than necessary, and it can be handled with a small capacity. Accordingly, storage equipment costs can be reduced. Further, the storage 55 can avoid a situation in which the remaining capacity becomes small and data cannot be stored.

  Further, the client 30 can request transmission of a plurality of 60-second moving image data included in the search list SLT to the server 50 in a lump.

  Thus, since the server 50 transmits a plurality of 60-second moving image data registered in the search list SLT to the client 30 at once, for example, even when transmitting moving image data of about 5 minutes exceeding 60 seconds, The server 50 does not need to transmit 60-second moving image data a plurality of times in response to a plurality of moving image acquisition requests, and can efficiently transmit a plurality of 60-second moving image data over about 5 minutes.

  The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, in the above embodiment, the search list and the 60-second moving image data are transmitted from the server to the client regardless of whether the search list and the 60-second moving image data are stored in the server. May be transmitted from the server to the client only when the message is stored in the server. Thereby, when not stored in the server, the client may acquire the search list and the 60-second moving image data directly from the digital tachograph. In this case, the search list and the 60-second moving image data are not transmitted through the server. It is possible to acquire moving image data quickly.

  Moreover, although the case where it applied to the digital tachograph which mounted the camera as an onboard equipment was shown in the said embodiment, an onboard equipment may be a drive recorder, an ETC apparatus with a camera, etc.

  Moreover, in the said embodiment, although the bus company was illustrated as a provider, a trucking company, a taxi company, etc. may be sufficient.
