The data collection device 10 is configured, for example, as a cloud server that provides a cloud service via a network such as the Internet or a mobile phone network. Vehicle data is collected from each in-vehicle device 100 based on the collection request. The data collection device 10 then provides the collected vehicle data to the user.

The in-vehicle device 100 includes various sensors such as a camera, an acceleration sensor, a GPS (Global Positioning System) sensor, a vehicle speed sensor, an accelerator sensor, a brake sensor, and a steering angle sensor, a storage device, a microcomputer, and the like. The in-vehicle device 100 acquires from the data collection device 10 a collection instruction in response to the collection request received by the data collection device 10, and collects (acquires) vehicle data from the vehicle V based on the collection instruction.

The camera described above can, for example, take an image of the surroundings of the vehicle V and output moving image data. Further, the acceleration sensor detects acceleration acting on the vehicle V, and the GPS sensor detects the position of the vehicle V. FIG.

Moreover, the steering angle sensor detects the steering angle of the steering wheel of the vehicle V. FIG. A drive recorder, for example, can be used as the in-vehicle device 100 .

Also, the in-vehicle device 100 appropriately uploads the collected vehicle data to the data collection device 10 . By using the drive recorder as the in-vehicle device 100 in this way, the in-vehicle components mounted on the vehicle V can be made more efficient. It should be noted that the in-vehicle device 100 and the drive recorder may be configured separately without using them together.

The user terminal 200 is a terminal used by a data user, and may be a notebook PC (Personal Computer), a desktop PC, a tablet terminal, a PDA (Personal Digital Assistant), a smart phone, an eyeglass type, or a watch type information processing device. Examples include a wearable device, which is a terminal. The user terminal 200 is an example of a terminal device, and the data user is an example of a user.

In the data collection system 1 according to this embodiment, the data collection device 10 collects vehicle data from the in-vehicle device 100 based on collection conditions specified via the user terminal 200 and provides the vehicle data to the user terminal 200 . can be done. By using the provided vehicle data, the data user of the user terminal 200 can analyze the behavior of the vehicle V for which the vehicle data was collected, the events occurring in the vehicle V, and the like.

A series of flows until vehicle data is provided to data users in the data collection system 1 will be described below with reference to FIGS. 1A to 1C. As shown in FIG. 1A, the data user first designates collection conditions using the user terminal 200 connected to the data collection device 10 .

Here, the collection conditions described above include various parameters such as a condition that triggers collection, and an example of a condition that triggers collection is, for example, when the vehicle speed exceeds a predetermined speed.

Further, when the collection conditions are specified, the data collection device 10 is added to the actual data R (an example of vehicle data) to be collected, and is used as index data for searching the actual data R and for grasping the outline. data for generating tag data T having the characteristics of That is, the tag data T is meta data in which the actual data R is turned into meta information. The data for generating the tag data T is generated based on the operation of the data user while using the program and data for generation stored in the user terminal 200 or the data collection device 10 .

Then, the specified collection conditions and the data for generating the generated tag data T are stored in the data collection device 10, distributed to the vehicle V that is the object of data collection, and also stored in the in-vehicle device 100. be done.

Next, each in-vehicle device 100 monitors the output data of various sensors, and when an event occurs that satisfies the stored collection conditions (here, when the vehicle speed exceeds a predetermined speed), the output data and Actual data R such as moving image data is stored in a storage device.

Each in-vehicle device 100 generates and stores tag data T corresponding to the actual data R based on the data for generating the tag data T and the actual data R stored therein. Then, each in-vehicle device 100 uploads the tag data T to the data collection device 10, and the data collection device 10 stores the tag data T. FIG. Note that the actual data R is not uploaded to the data collection device 10 at this time. That is, as shown in FIG. 1A, the data collection device 10 holds only the tag data T. FIG.

Then, when the data user connects to the data collection device 10 to check the collection status or collect the actual data R using the user terminal 200, the meta information based on the tag data T collected by the data collection device 10 is displayed. It is displayed on the user terminal 200 .

Then, as shown in FIG. 1B, when the data user desires to collect and transmit predetermined actual data R (vehicle data, such as video data), the user terminal 200 allows the collected actual data R to be Specify the corresponding tag data T. As a result, the user terminal 200 outputs a transmission request for predetermined actual data R (vehicle data) to the data collection device 10 . Then, the data collection device 10 outputs an instruction to transmit the actual data R (in other words, instruction data designating the actual data R) in response to the transmission request to the corresponding in-vehicle device 100 .

Thereafter, as shown in FIG. 1C, the designated actual data R is transmitted (uploaded) from each vehicle-mounted device 100 to the data collection device 10 and stored in the data collection device 10 based on the transmission instruction. Then, the data user accesses the actual data R stored in the data collection device 10 using the user terminal 200, and accesses or downloads the actual data R from the data collection device 10 to the user terminal 200. Transmission processing of R is performed.

From the viewpoint of the data capacity of the in-vehicle device 100, the actual data R uploaded to the data collection device 10 and the tag data T corresponding thereto should be deleted from the in-vehicle device 100 after being uploaded to the data collection device 10. is preferred.

Moreover, the tag data T is not data that is simply extracted from part of the actual data R, but allows the data user to grasp the outline of the actual data R and determine whether or not the actual data R is necessary. It is preferable that the information is converted to meta-information to some extent.

Here, in the present embodiment, the communication status image 210 indicating the communication status of vehicle data such as the actual data R is displayed on the user terminal 200 . Thus, in this embodiment, for example, the data user can accurately grasp the communication status of the actual data R (vehicle data).

More specifically, the communication status image 210 includes the vehicle data communication status between the vehicle data collection device 100 and the data collection device 10 and the vehicle data communication status between the data collection device 10 and the user terminal 200 . A communication status image and the like showing the communication status of the terminal device related to the data communication status are shown.

For example, when the user terminal 200 designates the tag data T corresponding to the actual data R to be collected and receives a transmission request for the actual data R from the user terminal 200, the data collection apparatus 10 and the in-vehicle apparatus 100 collect the data. In-vehicle device side communication status data relating to the communication status with the device 10 and terminal device side communication status data relating to the communication status between the data collecting device 10 and the user terminal 200 are collected.

Note that the timing of collecting the data of the communication status described above is merely an example and is not limited. Any other timing such as

The above-described communication status includes, for example, a status indicating that a transmission request for the actual data R has been transmitted (uploaded) from the user terminal 200 to the data collection device 10, A situation indicating that the transmission instruction has been transmitted (uploaded), a situation indicating that the in-vehicle device 100 is preparing to transmit the actual data R, and the actual data R is transmitted (uploaded) from the in-vehicle device 100 to the data collection device 10. ), a situation indicating that the actual data R has been transmitted (downloaded) from the data collection device 10 to the user terminal 200, and the like.

Then, the data collection device 10 generates a communication status image 210 based on the collected vehicle-mounted device side communication status data and terminal device side communication status data, and transmits the generated communication status image 210 to the user terminal 200. indicate. Although the communication status image 210 is generated by the data collection device 10 in the above description, it is not limited to this, and may be generated by the user terminal 200 .

The communication status image 210 schematically displays the communication status as an animation image. For example, in the communication status image 210, the user terminal 200 is displayed as an animation image of a notebook PC. The data collection device 10 is displayed as an animation image of the building of the management center that manages the data collection device 10, and the in-vehicle device 100 is displayed as an animation image of the vehicle. In addition, each animation image shown in FIG. 1C is an example and is not limited.

In the communication status image 210, arrows A1 to A4 are displayed between the user terminal 200 and the data collection device 10 and between the data collection device 10 and the in-vehicle device 100 to indicate the respective communication states.

For example, the arrow A1 corresponds to the transmission status of the transmission request from the user terminal 200 to the data collection device 10 . An arrow A2 corresponds to the transmission status of the transmission instruction from the data collection device 10 to the in-vehicle device 100 . An arrow A3 corresponds to the state of transmission of the actual data R from the in-vehicle device 100 to the data collection device 10, and an arrow A4 corresponds to the state of transmission of the actual data R from the data collection device 10 to the user terminal 200. FIG. In other words, the arrows A1 and A4 correspond to the terminal device side communication status, and the arrows A2 and A3 correspond to the in-vehicle device side communication status.

Then, the data collection device 10 changes the display mode of the communication status image 210 according to the in-vehicle device side communication status and the terminal device side communication status. For example, if the current communication situation is a communication situation in which actual data R is being transmitted from the in-vehicle device 100 to the data collection device 10, the data collection device 10 can highlight the corresponding arrow A3. For example, the data collection device 10 changes the display mode of the communication status image 210 by changing the color of the arrow A3 different from that of the other arrows or blinking the arrow A3.

As a result, for example, the data user can see the current communication status from the in-vehicle device 100 to the data collection device 10 by checking the portion of the communication status image 210 whose display mode has changed, here the highlighted arrow A3. It is possible to accurately grasp the progress of the process, such as the communication status in which the actual data R of is being transmitted.

Note that the change in the display mode of the communication status image 210 is not limited to the above-described change in color or blinking, and may be other changes such as enlarging or reducing the size of the arrow, for example.

Of the communication states described above, the transmission preparation processing of the actual data R in the in-vehicle device 100 is not indicated by an arrow in the communication situation image 210. By highlighting the device 100 by blinking it, the data user can understand that the in-vehicle device 100 is preparing for transmission.

Further, the data collection device 10 may display a message M indicating the communication status on the communication status image 210. FIG. As a result, the data collection device 10 allows the data user to more accurately grasp the communication status of the actual data R, more precisely, the progress status of various processes such as collection and provision of the actual data R. FIG.

As described above, in this embodiment, since the communication status image 210 is displayed as described above, it is possible, for example, to allow the data user to accurately grasp the communication status of the actual data R (vehicle data). can be done. Note that the communication status image 210 shown in FIG. 1C is an example and is not limited. Other examples of the communication status image 210 will be described later with reference to FIG. 6 onwards.

As described above, the communication status image 210 represents the in-vehicle device side communication status between the in-vehicle device 100 and the data collection device 10, the terminal device side communication status between the data collection device 10 and the user terminal 200, and the like. indicate. Note that the communication status image 210 shown in FIG. 5 is the same as the example shown in FIG. 1C, so detailed description thereof will be omitted.

The graph information 220 is data included in the actual data R, and is information indicating the vehicle speed of the vehicle V, the accelerator, and the like. Although vehicle speed, accelerator, brake, and steering angle are shown as graph information 220 in FIG. 5, these are only examples and are not limited. The map information 230 is data included in the actual data R, and is information indicating the position of the vehicle V on the map.

Next, other examples of the communication status image 210 will be described with reference to FIGS. 6 to 11. FIG. 6 to 11 are diagrams showing an example of the communication status image 210. FIG.

As shown in FIG. 6, the display control unit 13f can display the transmission progress status until the transmission of the actual data R is completed as a communication status image 210. FIG.

For example, after the user terminal 200 outputs a transmission request for the actual data R to the data collection device 10, the display control unit 13f transmits (provides) the actual data R to the user terminal 200 and the user terminal 200 and the user terminal 200. until the communication is completed, that is, for the entire transmission process related to the collection and provision of the actual data R, the status of the transmission process completed up to now (transmission progress) can be displayed as the communication status image 210 . In the example shown in FIG. 6, a graph indicating that 40% of the entire transmission process relating to the collection and provision of the actual data R has been completed is displayed in the display column P1.

As a result, for example, the data user can accurately grasp the communication status of the actual data R, more specifically, the progress status of the processing related to the collection and provision of the actual data R.

Further, as shown in FIG. 7, the display control unit 13f can display the estimated time until transmission of the actual data R to the user terminal 200 is completed as a communication status image 210. FIG. That is, the display control unit 13f can display the estimated time from when the actual data R is provided to the user terminal 200 until the communication with the user terminal 200 is completed as the communication status image 210. FIG.

For example, after the transmission request for the actual data R is transmitted from the user terminal 200 to the data collection device 10, the display control unit 13f provides the actual data R to the user terminal 200 and completes the transmission of the actual data R. Until, that is, until the entire processing related to the collection and provision of the actual data R is completed, the estimated completion time can be estimated, and the estimated completion time can be displayed as the communication status image 210 . In the example shown in FIG. 7, a message is displayed in the display field P2 indicating that the remaining estimated time of completion is five minutes.

As a result, for example, the data user can accurately grasp the communication status of the actual data R, more specifically, the progress status of the processing related to the collection and provision of the actual data R.

Further, as shown in FIG. 8, the display control unit 13f controls the degree of completion of transmission of the actual data R between the in-vehicle device 100 and the data collection device 10, and the degree of transmission between the data collection device 10 and the user terminal 200. The degree of completion of transmission of the actual data R during the period can be displayed as the communication status image 210 .

For example, the display control unit 13f determines the degree of completion of transmission of the actual data R between the in-vehicle device 100 and the data collection device 10, and transmission of the actual data R between the data collection device 10 and the user terminal 200. can be separately displayed as the communication status image 210 . Specifically, the display control unit 13f displays the degree of completion of transmission from the data collection device 10 to the in-vehicle device 100 in the display field P3a for the degree of completion of transmission from the user terminal 200 to the data collection device 10. A graph is displayed in column P3b. Similarly, the display control unit 13f displays the degree of completion of transmission from the in-vehicle device 100 to the data collection device 10 in the display column P3c, and displays the degree of completion of transmission from the data collection device 10 to the user terminal 200 in the display column P3d. to display as a graph.

As a result, for example, the data user can more accurately grasp the communication status of the actual data R, more precisely, the progress status of the processing related to the collection and provision of the actual data R.

Further, as shown in FIG. 9, the display control unit 13f controls the transmission speed (communication speed) of the actual data R between the in-vehicle device 100 and the data collection device 10, and the transmission speed between the data collection device 10 and the user terminal 200. The transmission speed (communication speed) of the actual data R during the period can be displayed as the communication status image 210 .

For example, the display control unit 13f displays the transmission speed of the actual data R from the in-vehicle device 100 to the data collection device 10 in the display column P4a, and the transmission speed of the actual data R from the data collection device 10 to the user terminal 200 in the display column P4a. It can be displayed as a message on P4b.

As a result, for example, by checking the communication speed, the data user can grasp the communication status of the actual data R, and at the same time, check the progress status, such as whether the processing related to the collection and provision of the actual data R can be performed smoothly. Accurate judgments can be made.

Further, for example, the display control unit 13f can display the transmission speed difference in a display field P4c in addition to or instead of the display fields P4a and P4b in which the transmission speeds are displayed. Specifically, the display control unit 13f controls the transmission speed of the actual data R between the in-vehicle device 100 and the data collection device 10 and the transmission speed of the actual data R between the data collection device 10 and the user terminal 200. A transmission speed difference can be displayed as a communication status image 210 .

As a result, for example, the data user can grasp the communication status of the actual data R by confirming the transmission speed difference, and in the processing related to the collection and provision of the actual data R, the device in which the actual data R etc. It is possible to make accurate judgments regarding the progress status, such as whether or not a task is delayed.

Further, the instruction to transmit the actual data R described above may be output to a plurality of in-vehicle devices 100 . In such a case, the on-vehicle device side communication status corresponding to the plurality of on-board devices 100 can be displayed as the communication status image 210 . Specifically, as an example is shown in FIG. 10, the display control unit 13f can display the communication statuses of the plurality of in-vehicle devices 100 on the communication status image 210. FIG.

For example, when a transmission instruction corresponding to a transmission request is output to a plurality of in-vehicle devices 100, that is, when there are a plurality of vehicles from which actual data R is to be collected, the display control unit 13f (in-vehicle device side communication status) is displayed on the communication status image 210 . Then, for example, the display control unit 13f can change the display mode of the in-vehicle device 100 for which transmission of the actual data R to the data collection device 10 has been completed, in other words, it can be highlighted. Note that the example of FIG. 10 indicates that communication from the in-vehicle device 100a to the data collection device 10 has been completed.

As a result, for example, even if there are a plurality of vehicles for which the actual data R is collected, the data user can check the communication status of the actual data R, more specifically, the progress of processing related to the collection and provision of the actual data R (here Then, it becomes possible to accurately grasp the progress of the processing of the in-vehicle device 100 .

Note that when there are a plurality of vehicles for which the actual data R is to be collected, in the example of FIG. It is not limited to this. That is, as an example is shown in FIG. 11, a numerical value or the like indicating the communication status of a plurality of in-vehicle devices 100 may be displayed in the communication status image 210. FIG.

For example, when there are a plurality of vehicles for which the actual data R is to be collected, the display control unit 13f displays the plurality of vehicle-mounted devices 100 (here, the vehicle-mounted devices 100a to 100c) in the communication status image 210 in the example of FIG. However, it is not limited to this. That is, as an example is shown in FIG. 11, a numerical value or the like indicating the communication status of a plurality of in-vehicle devices 100 may be displayed in the communication status image 210. FIG.

For example, the display control unit 13f may display the number of collection target vehicles and the number of collection target vehicles for which transmission of the actual data R to the data collection device 10 has been completed as a message in the display field P5. Note that the example of the display field P5 in FIG. 11 indicates that 30 of the 60 collection target vehicles have completed transmission of the actual data R to the data collection device 10 .

As a result, for example, when there are a plurality of vehicles for which the actual data R is to be collected, the data user can check the communication status of the actual data R, more specifically, the progress of processing related to the collection and provision of the actual data R (in this case, the in-vehicle device 100 process progress) can be accurately grasped.

In the above description, the number of collection target vehicles that have completed transmission of the actual data R is displayed. However, the present invention is not limited to this. The number of units to which the actual data R has not yet been transmitted may be displayed.

Further, the display control unit 13f, instead of or in addition to the numerical value indicating the communication status of the plurality of in-vehicle devices 100, calculates the ratio of the number of collection target vehicles for which transmission of the actual data R to the data collection device 10 has been completed. You may display the numerical value and graph shown in the display column P6 shown by the imaginary line. Note that the example of the display column P6 in FIG. 11 indicates that transmission of the actual data R to the data collecting device 10 has been completed for 50% of the collection target vehicles.

Further, the display control unit 13f may display the communication statuses of the plurality of in-vehicle devices 100 with animation images (icons) 100d showing the in-vehicle devices 100 instead of or in addition to the display fields P5 and P6 described above. For example, as shown in FIG. 11, the display control unit 13f changes the size of the animation image 100d showing the in-vehicle device 100 according to the increase or decrease in the number of collection target vehicles. That is, the display control unit 13f enlarges the animation image 100d when the number of vehicles to be collected increases, and decreases the animation image 100d when the number of vehicles to be collected decreases, thereby increasing or decreasing the number of vehicles to be collected. can be displayed.

Then, the display control unit 13f can display the ratio of the number of collection target vehicles for which transmission of the actual data R to the data collection device 10 has been completed using the animation image 100d showing the in-vehicle device 100. FIG. For example, the display control unit 13f changes the color ratio of the animation image 100d (in this case, the animation image 100d of the vehicle) according to the ratio of the number of units for which transmission of the actual data R is completed. communication status can be displayed. In the example of the animation image 100d of FIG. 11, by coloring 50% of the lower half, 50% of the collection target vehicles out of the collection target vehicles can transmit the actual data R to the data collection device 10. indicates that it is complete.

In the example of FIG. 11, the colored portion of the entire animation image 100d indicates the ratio of the number of devices for which transmission of the actual data R has been completed, but this is not a limitation. That is, for example, the display control unit 13f gradually changes the color of the entire animation image 100d or changes the flashing speed of the animation image 100d according to the ratio of the number of units for which transmission of the actual data R is completed. , or other methods may be used to display the communication statuses of the plurality of in-vehicle devices 100 .

By displaying the communication status shown in FIG. 11 in this way, for example, the data user can accurately grasp the communication status of the actual data R even when there are a plurality of vehicles for which the actual data R is collected. it becomes possible to

In the example of the communication status image 210 shown in FIGS. 6 to 11, the transmission status from the user terminal 200 to the in-vehicle device 100 via the data collection device 10 (so-called upstream transmission status) and the in-vehicle device 100 to the user terminal 200 via the data collection device 10 (so-called downlink transmission status). You may do so. For example, since the amount of data is relatively large in the downstream direction for transmitting the actual data R including images, the display control unit 13f can display only the transmission status in the downstream direction to inform the data user of the communication status. It is possible to grasp it accurately.

Also, the display control unit 13f may display the communication status image 210 according to the data volume. That is, the display control unit 13f acquires the data volume of the actual data R (vehicle data), and when it is determined that the acquired data volume is a predetermined value or more and is relatively large, the display control unit 13f A communication status image 210 may be displayed. In this way, by displaying the communication status image 210 only when the actual data R having a relatively large data volume is transmitted, for example, when it is estimated that the data user wants to grasp the communication status, the communication It becomes possible to display the situation image 210 .

Further, for example, when the detecting unit 103b detects occurrence of an event that serves as a trigger for uploading vehicle data to the data collecting device 10 under the collection conditions, the detecting unit 103b causes the uploading unit 103e to upload the vehicle data.

The collecting unit 103 c collects vehicle data based on the vehicle data collection instruction, and stores the collected vehicle data in the storage unit 102 .
