Description

Disclosure embodiments relate to reporting devices, reporting systems and reporting methods.

Conventionally, a technique has been proposed in which, for example, when a vehicle falls into an emergency state due to an accident or the like, a notification device mounted on the vehicle notifies the emergency notification center (see, for example, Patent Document 1). The emergency call center is also called an emergency response agency (PSAP: Public Safety Answering Point).

In such a technique, when the acceleration of the vehicle exceeds a predetermined threshold value, it is presumed that a large impact accident such as a collision accident has occurred, and the PSAP is notified. When PSAP receives such a report, it makes a request for dispatching an emergency vehicle or a police vehicle to a requesting organization such as a hospital or police.

Further, there is also known a technique of notifying PSAP by a user pressing a notification button or the like mounted on the vehicle even if the acceleration of the vehicle does not exceed a predetermined threshold value.

Hereinafter, embodiments of the reporting device, reporting system, and reporting method disclosed in the present application will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments shown below.

First, an outline of the reporting method according to the embodiment will be described with reference to FIG. FIG. 1 is a schematic explanatory view of a reporting method according to an embodiment. In FIG. 1, a reporting system 1 to which the reporting method according to the embodiment is applied will be described as an example.

As shown in FIG. 1, the notification system 1 according to the embodiment includes a center server 10 and in-vehicle devices 100-1, 100-2, ... Mounted on the vehicles V-1, V-2, respectively. In the following, the term "vehicle V" will be used to refer to the vehicle in general, and the term "vehicle device 100" will be used to refer to the in-vehicle device in general.

The center server 10 is a device provided in, for example, a PSAP and receives an emergency call transmitted from the in-vehicle device 100 via a network N such as the Internet or a mobile phone network.

The content of the received report is confirmed by, for example, the operator OP of PSAP, and the dispatch request is made to the requesting organization such as the hospital or the police according to the content of the report. In the following, the emergency call signal transmitted from the vehicle-mounted device 100 to the center server 10 will be referred to as MSD (Minimum Set of Data).

By the way, in the reporting method as a comparative example, the vehicle information of the vehicle on which the in-vehicle device 100 is mounted is transmitted as the MSD. Such vehicle information includes the vehicle classification, vehicle type, number, position information, reporting time, etc. of the corresponding vehicle V, but includes information that can confirm the status of the passenger (hereinafter referred to as "user") of the vehicle V. Not done. Therefore, it is difficult to grasp the user's situation in PSAP by the reporting method as a comparative example. Therefore, for example, when multiple reports are received at almost the same time, it is difficult to determine the priority of rescue.

Therefore, in the reporting method according to the embodiment, the in-vehicle device 100 transmits the MSD including the user's biological information in addition to the vehicle information to the center server 10. Then, the center server 10 determines the degree of urgency for each MSD based on the biometric information.

After that, the center server 10 decides to instruct the operator OP to request the dispatch with the priority according to the determined urgency. Then, the operator OP decides to make a dispatch request to the requesting organization in response to such an instruction.

Specifically, the in-vehicle device 100 includes, for example, a camera, an acceleration sensor, a GPS (Global Positioning System) sensor, a car navigation device having various sensors including a biological sensor, a storage device, a microcomputer, and an ECU (Electronic Control). It is configured as a Unit).

For example, when the SOS button 120 (see FIG. 2 or the like) mounted on the vehicle V is pressed by the user, the in-vehicle device 100 transmits an MSD including the user's biometric information (step S1). In FIG. 1, it is assumed that the MSDs are transmitted from the in-vehicle devices 100-1 and 100-2 at almost the same time.

When the center server 10 receives these MSDs (step S2), the center server 10 determines the degree of urgency for each MSD based on the biometric information of the user included in the MSDs (step S3). Such a determination can be performed using, for example, an analysis model that outputs the degree of urgency when each element included in the biological information is input as a parameter.

Such an analysis model can be generated in advance by, for example, performing machine learning using biometric information as teacher data.

Then, the center server 10 instructs the operator OP to request the dispatch with the priority according to the urgency determined in step S3 (step S4). Then, the operator OP makes a dispatch request to the requesting organization based on the instruction (step S5).

As described above, in the reporting method according to the embodiment, the in-vehicle device 100 transmits the MSD including the user's biological information in addition to the vehicle information to the center server 10. Then, the center server 10 determines the degree of urgency for each MSD based on the biometric information.

After that, the center server 10 decides to instruct the operator OP to request the dispatch with the priority according to the determined urgency. Then, the operator OP decides to make a dispatch request to the requesting organization in response to such an instruction.

Therefore, according to the reporting method according to the embodiment, it is possible to realize an efficient dispatch request according to the situation.

The contents of the biometric information added to the MSD will be described later with reference to FIGS. 3A and later.

Hereinafter, a configuration example of the reporting system 1 to which the reporting method according to the above-described embodiment is applied will be described more specifically.

It can be integrated and configured.

Further, in the description using FIG. 2, the description of the components already described may be simplified or omitted.

As described above, as shown in FIG. 2, the reporting system 1 according to the embodiment includes a center server 10 and an in-vehicle device 100.

First, the center server 10 will be described. The center server 10 includes a communication unit 11, a storage unit 12, and a control unit 13.

The communication unit 11 is realized by, for example, a NIC (Network Interface Card) or the like. The communication unit 11 is connected to the network N by wire or wirelessly, and transmits / receives information to / from the in-vehicle device 100 via the network N.

As described above, the analysis model 12a is an urgency determination model that functions as a function that outputs the urgency when each element included in the biological information is input as a parameter.

The analysis model 12a is generated in advance by, for example, performing machine learning using biometric information as teacher data. As the machine learning algorithm, various known algorithms such as deep learning can be used.

The request destination information DB 12b is a database of information about the request destination organization, and includes identification information of the request destination organization, a location, contact information, requestable contents, and the like.

The control unit 13 is a controller, and for example, various programs stored in a storage device inside the center server 10 by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like use the RAM as a work area. It is realized by being executed. Further, the control unit 13 can be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The control unit 13 includes an acquisition unit 13a, an analysis unit 13b, a determination unit 13c, and an instruction unit 13d, and realizes or executes an information processing function or operation described below.

The determination unit 13c determines the degree of urgency for each MSD acquired by the analysis unit 13b, and determines the priority for each MSD according to the degree of urgency.

The instruction unit 13d extracts the optimum request destination organization from the request destination information DB 12b based on the content of the MSD, and instructs the operator OP to make a dispatch request with the priority determined by the determination unit 13c. The instruction content is displayed, for example, on the display of the terminal used by the operator OP.

Next, the in-vehicle device 100 will be described. The in-vehicle device 100 includes a communication unit 101, a storage unit 102, and a control unit 103. Further, as described above, the in-vehicle device 100 is connected to various sensors 150 such as a camera, an acceleration sensor, a GPS sensor, and a biological sensor.

The communication unit 101 communicates between the network N and various sensors 150 and the in-vehicle device 100. The communication unit 101 realizes communication with the network N by a wireless communication interface. For the wireless communication interface, for example, WiFi (Wireless Fidelity) or Bluetooth (registered trademark) may be used. The wireless communication interface is wirelessly connected to the network N by using, for example, the tethering function of a smartphone. The communication unit 101 transmits / receives information to / from the center server 10 via the network N.

In addition, the communication unit 101 communicates with various sensors 150. The communication unit 101 realizes communication with various sensors 150 by a CAN (Controller Area Network) bus. The communication unit 101 receives the output data of the various sensors 150. Communication with the various sensors 150 may be performed by another protocol of CAN. It may also be performed wirelessly.

The storage unit 102 is realized by, for example, a semiconductor memory element such as a RAM or a flash memory, and in the example of FIG. 2, the vehicle information 102a and the biological information 102b are stored.

The vehicle information 102a is information on the vehicle V, and includes static information such as a vehicle classification such as an engine vehicle, a vehicle type, and a number. Further, it may include dynamic information such as position information acquired from various sensors 150.

The biological information 102b is information about the user's biological body, and includes the user's pulse, the amount of sweat, the body temperature, and the like. The biological information 102b is monitored at any time via the biological sensors included in the various sensors 150, and a predetermined amount is always accumulated in the biological information 102b.

For example, in the case of a driver's use, the biosensor can be provided at a portion of the steering wheel that comes into contact with the skin when grasped. In addition, the biosensor may be provided as a wearable device. Further, for example, a camera for in-vehicle imaging for driving assistance or the like or an infrared sensor for detecting the line of sight may be used as a biosensor.

The control unit 103 is a controller like the control unit 13, and is realized by, for example, executing various programs stored in the storage device inside the in-vehicle device 100 by the CPU, MPU, or the like using the RAM as a work area. Will be done. Further, the control unit 103 can be realized by, for example, an integrated circuit such as an ASIC or FPGA.

The control unit 103 includes an acquisition unit 103a, a generation unit 103b, and a transmission unit 103c, and realizes or executes the functions and operations of information processing described below.

The acquisition unit 103a receives output data from various sensors 150, and acquires a dynamic situation that changes from moment to moment based on the output data. For example, the acquisition unit 103a updates the vehicle information 102a with the position information of the GPS sensor that changes from moment to moment.

Further, for example, the acquisition unit 103a monitors the user's state at any time via the biological sensor, and constantly accumulates a predetermined amount in the biological information 102b.

Further, the acquisition unit 103a acquires the occurrence of an event in which the user presses the SOS button 120 connected to the in-vehicle device 100.

The generation unit 103b generates an MSD based on the vehicle information 102a and the biological information 102b when the acquisition unit 103a acquires the event occurrence of the SOS button 120 pressing by the user, that is, when the SOS button 120 is pressed.

Here, the contents of the MSD generated by the generation unit 103b will be specifically described with reference to FIGS. 3A to 3D. 3A to 3D are explanatory views (No. 1) to (No. 4) of the MSD.

As shown in FIG. 3A, the MSD is generated when the user presses the SOS button 120. The MSD includes vehicle information and biometric information. As the biological information, a predetermined latest amount when the SOS button 120 is pressed is added.

As shown in FIG. 3B, the vehicle information of the MSD includes a vehicle classification such as an engine vehicle and an EV (Electric Vehicle) vehicle, a vehicle type, a number, a position information, a reporting time which is the time when the SOS button 120 is pressed, and the like.

In addition, the biological information of MSD includes pulse, sweat amount, body temperature, camera image, infrared ray detection information and the like. As shown in the figure, the biometric information of the MSD may be provided for each user such as the driver, the passenger # 1, and so on.

Further, in FIG. 3A, the case where a predetermined latest portion is added to the biological information of MSD is taken as an example, but as shown in FIG. 3C, a predetermined past portion is further added in addition to the predetermined latest portion. May be good. As a result, the center server 10 can analyze, for example, the temporal transition of the user's physical condition for a predetermined time, and can accurately grasp the user's state.

Further, the time transition may be processed and prepared on the in-vehicle device 100 side, and may be added to the MSD as biometric information as shown in FIG. 3D. In such a case, there is an advantage that the processing load on the center server 10 side can be reduced.

Returning to the description of FIG. The transmission unit 103c transmits the MSD generated by the generation unit 103b to the center server 10.

By the way, up to now, the case where the center server 10 receives a plurality of MSDs from a plurality of in-vehicle devices 100 at almost the same time has been taken as an example, but even when the center server 10 receives MSDs in a single shot, the urgency is determined based on biometric information. However, there is no change in instructing the dispatch request according to the degree of urgency. The case of receiving the MSD in such a single shot will be described with reference to FIGS. 4A and 4B.

4A and 4B are explanatory views (No. 1) and (No. 2) when the center server 10 receives the MSD in a single shot.

As shown in FIG. 4A, the vehicle-mounted device 100 first transmits the MSD (step S11). Then, the center server 10 receives this (step S12) and determines the degree of urgency based on the biological information included in the MSD (step S13).

Then, the center server 10 instructs the operator OP to dispatch according to the determined urgency (step S14), and in response to this, the operator OP makes a dispatch request to the requesting organization. (Step S15). FIG. 4A differs from the example of FIG. 1 in that the priority according to the urgency is not considered, but even when the MSD is received in a single shot, the priority is considered depending on the time difference. The need comes out.

An example of such a case is shown in FIG. 4B. As shown in FIG. 4B, it is assumed that the in-vehicle device 100-1 has transmitted the MSD # 1 (step S21).

Then, the center server 10 receives the MSD # 1 and determines the degree of urgency (step S22), and prepares a dispatch request instruction corresponding to the determination (step S23).

Then, it is assumed that the in-vehicle device 100-2 has transmitted the MSD # 2 (step S24). In such a case, the center server 10 redetermines the urgency of MSDs # 1 and # 2 (step S25). As a result, it is assumed that MSD # 2 has a higher degree of urgency (step S26).

Then, the center server 10 instructs the operator OP to give priority to the MSD # 2 based on the result of the re-determination (step S27). As a result, even if the center server 10 receives the MSD in a single shot, if the urgency of the late MSD is high, the late MSD is given priority before the dispatch request corresponding to the early MSD. Can be handled by.

Next, a modification of the MSD will be described with reference to FIGS. 5A and 5B. 5A and 5B are explanatory views (No. 1) and (No. 2) of the MSD according to the modified example.

By the way, so far, the case where the acceleration is not included in the vehicle information of the MSD when the SOS button 120 is pressed has been taken as an example (see FIG. 3B). When the acceleration exceeds a predetermined threshold value indicating a strong impact, the notification system 1 can automatically transmit the MSD without pressing the SOS button 120, and the acceleration can be included in the MSD in such a case. Is.

However, as shown in FIG. 5A, the acceleration may be included in the vehicle information of the MSD when the SOS button 120 is pressed. Further, the content of the biometric information of the MSD may be changed according to the acceleration.

When the MSD when the SOS button 120 is pressed includes an acceleration, the acceleration itself is weaker than when the MSD is automatically transmitted (hereinafter, referred to as "weak acceleration" for convenience). I can say. However, even though the MSD is not automatically transmitted, if the SOS button 120 is pressed, the vehicle V may be impacted to some extent, affecting the physical condition of the user.

Therefore, as shown in FIG. 5B, the level may be divided even in such a weak acceleration, and the elements included in the biological information may be changed according to the level. For example, if the weak acceleration is less than a predetermined value, the element to be included in the biological information may be the minimum necessary, and if the weak acceleration is more than the predetermined value, another element (here, a camera image) may be added.

This can contribute to improving the accuracy of the analysis of the user's state when it is considered that a certain degree of impact has been received, although the acceleration is weak.

Next, the processing procedure executed by the reporting system 1 according to the embodiment will be described with reference to FIG. FIG. 6 is a processing sequence executed by the notification system 1 according to the embodiment.

As shown in FIG. 6, the in-vehicle device 100 collects sensor data from various sensors 150 (step S101). This is repeated until the SOS button 120 is pressed in step S102 (steps S102, No).

Then, when the SOS button 120 is pressed (step S102, Yes), the in-vehicle device 100 extracts the biological information to be added to the MSD (step S103) and generates the MSD (step S104). Then, the generated MSD is transmitted to the center server 10 (step S105).

Then, the center server 10 receives the MSD (step S106) and determines the degree of urgency based on the biological information contained in the MSD (step S107). Then, the center server 10 instructs the operator OP to request the dispatch with the priority according to the determined urgency (step S108). Then, the operator OP makes a dispatch request (step S109).

As described above, the vehicle-mounted device 100 (corresponding to an example of the "reporting device") according to the embodiment is the vehicle-mounted device 100 mounted on the vehicle V, and includes an acquisition unit 103a and a transmission unit 103c. The acquisition unit 103a acquires biometric information of the user of the vehicle V (corresponding to an example of the "passenger"). When making an emergency call, the transmission unit 103c has a center server 10 (corresponding to an example of a "server device") provided so as to be able to determine the degree of urgency based on the biometric information, and has an MSD ("" Equivalent to an example of an "emergency call signal") is sent.

Therefore, according to the in-vehicle device 100 according to the embodiment, it is possible to realize an efficient dispatch request according to the situation.

Further, when the center server 10 receives a plurality of MSDs, the center server 10 determines the priority of the MSDs according to the urgency.

Therefore, according to the in-vehicle device 100 according to the embodiment, it is possible to appropriately process a plurality of MSDs according to the priority based on the urgency, and it is possible to realize an efficient dispatch request.

Further, when the center server 10 receives the later MSD before the dispatch request to the requesting organization according to the urgency of the first MSD, the center server 10 re-determines the urgency and gives priority based on the result of the re-judgment. To determine.

Therefore, according to the in-vehicle device 100 according to the embodiment, if the urgency of the later MSD is high, the later MSD can be preferentially handled before the dispatch request corresponding to the earlier MSD.

Further, the acquisition unit 103a acquires the biometric information from a sensor provided at a portion of the steering wheel of the vehicle V that comes into contact with the skin when gripped, or a sensor provided as a wearable device.

Therefore, according to the in-vehicle device 100 according to the embodiment, it is possible to easily monitor the biometric information of the user at any time.

In addition, the biometric information includes at least one of the user's pulse, sweat volume, and body temperature.

Therefore, according to the in-vehicle device 100 according to the embodiment, it is possible to analyze the user's state from at least one of the user's pulse, sweat amount, and body temperature user.

Further, the transmission unit 103c transmits an MSD having different contents of the biometric information according to the situation of the vehicle V.

Therefore, according to the in-vehicle device 100 according to the embodiment, the accuracy of the analysis of the user's state is improved depending on the situation of the vehicle V, for example, when it is considered that a certain degree of impact has been received although the acceleration is weak. Can contribute to.

In the above-described embodiment, the case where the operator OP finally makes a dispatch request to the request destination organization is given as an example. For example, the instruction unit 13d of the center server 10 uses automatic voice or the like to request the request destination organization. It is also possible to automatically make a request for dispatch to.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described as described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
