More specifically, each of the first terminals 200 uploads the current position, orientation, posture, vibration, speed, battery voltage, and the like of the vehicle 500 to the server 100, so that the possibility that the vehicle 500 has been stolen may be increased. The server 100 determines whether or not it is high. When it is determined that the possibility that the vehicle 500 has been stolen is high, the server 100 transmits a notification of a warning to that effect to the second terminal 300 of the user who is the owner of the vehicle 500. is there.
<Configuration of first terminal 200>

  Hereinafter, the configuration and function of each device configuring the network system 1 according to the present embodiment will be described. First, the configuration of first terminal 200 attached to vehicle 500 in network system 1 according to the present embodiment will be described.

  Note that the first terminal 200 is attached to a vehicle 500 such as an automobile, a motorcycle, a bicycle, an electric motorcycle, a boat, or the like so that the voltage of a battery of the vehicle 500 can be measured. More specifically, first terminal 200 is preferably attached to vehicle 500 at a predetermined position and in a predetermined posture in order to accurately measure the direction, posture, and the like of vehicle 500. However, by running the vehicle 500 for several minutes in a state where the first terminal 200 is attached, the direction and orientation of the first terminal 200 with respect to the orientation and posture of the vehicle 500 are specified in advance, and thereby, The form which calculates the direction and attitude of the vehicle 500 based on the direction and attitude of the first terminal 200 may be used.

  Referring to FIG. 2, first terminal 200 mainly includes an MCU (Micro Controller Unit) 210, a position information acquisition unit 230, a communication unit 260, a motion sensor 270, a DC / DC converter 280, A battery voltage monitor 290 and the like are mounted.

  More specifically, the MCU 210 includes a processor, a memory such as a RAM (Random Access Memory), and various ROMs (Read-Only Memory). The processor controls each unit of the first terminal 200 based on programs and data in the memory.

  The location information acquisition unit 230 has a GNSS (Global Navigation Satellite System) function and the like, and periodically updates the current location and time of the first terminal 200, that is, the vehicle 500, based on a signal acquired by a GNSS antenna. The data is provided to the MCU 210. For example, the MPU 210 periodically uploads the data measured by the position information acquisition unit 230 to the server 100 using the communication unit 260.

  The motion sensor 270 periodically measures the direction, posture, and vibration of the vehicle 500, that is, the direction, posture, and vibration of the first terminal 200 attached to the vehicle 500 in a predetermined posture, and transmits the measured data to the MPU 210. Enter it regularly. As shown in FIG. 3, while the engine of the vehicle 500 is starting, the motion sensor 270 detects a small vibration due to the vibration of the engine and inputs the small vibration to the MPU 210. Then, while the vehicle 500 is traveling, the motion sensor 270 detects a large vibration caused by the shake of the vehicle 500 and inputs the vibration to the MPU 210. When the engine of vehicle 500 is stopped, motion sensor 270 does not detect vibration of the engine.

  Returning to FIG. 2, DC / DC converter 280 supplies electric power from battery 501 to each unit of first terminal 200.

  Battery voltage monitor 290 measures the voltage of battery 501 and outputs the measurement result to MCU 210. As shown in FIG. 3, while the engine of the vehicle 500 is starting, the voltage of the battery 501 rises and falls, so that the battery voltage monitor 290 inputs the value of the fluctuating voltage to the MPU 210. Note that while the engine of the vehicle 500 is stopped, the voltage of the battery 501 hardly fluctuates.

The communication unit 260 has an LTE antenna, a SIM card, and the like, and transmits and receives data to and from the server 100 via a carrier network, the Internet, or another communication terminal. For example, the MPU 210 periodically transmits the current position information acquired by the position information acquisition unit 230, information indicating the magnitude of vibration acquired by the motion sensor 270, voltage information measured by the battery voltage monitor 290, and the like to the communication unit 260. And upload it to the server 100.
<Configuration of server 100>

  Next, a configuration of the server 100 in the network system 1 according to the present embodiment will be described. As shown in FIG. 4, the server 100 includes, as main components, a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, and a communication interface 160.

  The CPU 110 realizes the theft notification service while controlling each unit of the server 100 by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120 and executes various processes described below by referring to various data.

  The memory 120 is realized by various RAMs and ROMs, and may be included in the server 100, may be removable from various interfaces of the server 100, or may be accessed from the server 100. It may be a database in other possible devices. The memory 120 stores a program executed by the CPU 110, data generated by execution of the program by the CPU 110, user information data 121, vehicle information data 122, and the like.

  Next, information processing of the server 100 according to the present embodiment will be described with reference to FIG. When receiving data from the first terminal 200 via the communication interface 160, the CPU 110 of the server 100 executes the following processing.

  First, the CPU 110 reads the identification information of the first terminal 200 from the data received from the first terminal 200, and specifies the user with reference to the user information data 121 (step S102). The CPU 110 acquires various measurement data from the data received from the first terminal 200 (Step S104). For example, CPU 110 acquires information indicating the voltage of battery 501 of vehicle 500 and information indicating the vibration of vehicle 500.

  Then, CPU 110 determines whether an abnormal situation has occurred in vehicle 500 based on the measurement data (step S106). For example, CPU 110 determines whether the voltage of the battery of vehicle 500 fluctuates above a predetermined level, for example, 5% or higher, or determines whether vehicle 500 is vibrating. Then, if the voltage of the battery of vehicle 500 is hardly fluctuating, but vehicle 500 is vibrating, it is determined that there is a high possibility that vehicle 500 has been stolen (YES in step S106). Conversely, when the vehicle 500 is not vibrating, it is determined that the possibility of theft is low, and when the voltage of the battery 501 of the vehicle 500 fluctuates more than a predetermined value, it is determined that the possibility of theft is low. . This determination method is particularly effective when the battery 501 of the vehicle 500 is charged by another driving force generating device such as a gasoline engine.

  As described above, when it is determined that vehicle 500 has been stolen and carried (YES in step S106), CPU 110 outputs the second terminal of the user of vehicle 500 via communication interface 160. A notification is sent to 300 indicating that there is a high possibility that vehicle 500 has been stolen and carried (step S108). At this time, it is preferable that the CPU 110 provides the user's second terminal 300 with the current position of the vehicle 500, measurement results, and the like.

On the other hand, if it is not determined that vehicle 500 has been stolen and carried (NO in step S106), CPU 110 transmits the next measurement data from first terminal 200 via communication interface 160. Await.
<Configuration of second terminal 300>

  Next, one mode of the configuration of the second terminal 300 configuring the network system 1 will be described. The second terminal 300 is a device capable of data communication with the server 100, such as a smartphone, a wearable terminal, a tablet, a personal computer, a speaker, or the like. The second terminal 300 includes, as main components, a CPU 310, a memory 320, a display 330, an operation unit 340, a communication interface 360, a speaker 370, a microphone 380, and the like.

  The CPU 310 controls each unit of the second terminal 300 by executing a program stored in the memory 320 or an external storage medium.

  The memory 320 is realized by various RAMs and various ROMs. The memory 320 stores programs executed by the CPU 310, data generated by executing the programs by the CPU 310, text data, image data, audio data received from the server 100, data input via the operation unit 340, and the like. Remember.

  The display 330 outputs characters, images, and the like based on a signal from the CPU 310. Operation unit 340 receives a command from a user and inputs the command to CPU 310. The display 330 and the operation unit 340 may be realized by the touch panel 350.

  The communication interface 360 is realized by a communication module such as a wireless LAN communication or a wired LAN. The communication interface 360 transmits and receives data to and from another device such as the server 100 by wire communication or wireless communication.

  Speaker 370 outputs sound based on a signal from CPU 310. Microphone 380 creates an audio signal based on external audio and inputs the signal to CPU 310.

In the present embodiment, CPU 310 receives theft detection data from server 100 via communication interface 360. The CPU 310 outputs a warning sound from the speaker 370 based on the received data, the possibility that the display 330 may have stolen, the current position, the moving direction, the degree of vibration, and the remaining battery level of the vehicle 500 of the user. And so on.
<Second embodiment>

  In the above embodiment, server 100 determines that there is a high possibility that vehicle 500 has been stolen when server 500 is vibrating even though the voltage of battery 501 of vehicle 500 has not fluctuated. Was something. However, another determination method may be used. For example, CPU 110 of server 100 determines whether the voltage of battery 501 of vehicle 500 is decreasing at a predetermined pace or more, for example, at 1% or more in five minutes, or when vehicle 500 vibrates. Or not.

  This determination method is particularly effective, for example, when the vehicle 500 is an electric vehicle or an electric bicycle without a gasoline engine, as shown in FIG.

  Then, when the voltage of the battery 501 of the vehicle 500 has hardly decreased, but the vehicle 500 is vibrating, it is determined that there is a high possibility that the vehicle 500 has been stolen (Step S106 in FIG. 7). YES). Conversely, when the vehicle 500 is not vibrating, it is determined that the possibility of theft is low, and when the voltage of the battery 501 of the vehicle 500 is decreasing at a predetermined pace or more, the possibility of theft is low. to decide.

  Alternatively, in step S106 of FIG. 7, server 100 may determine the possibility of vehicle 500 being stolen based on information indicating the voltage of battery 501 of vehicle 500 and current position information and speed information of vehicle 500. . For example, CPU 110 determines whether or not the voltage of battery 501 of vehicle 500 fluctuates more than a predetermined value, or determines whether or not vehicle 500 is moving. If the voltage of the battery 501 of the vehicle 500 hardly fluctuates and the vehicle 500 is moving, it is determined that the possibility that the vehicle 500 has been stolen is high. Conversely, when the vehicle 500 is not moving, it is determined that the possibility of theft is low, and when the voltage of the battery 501 of the vehicle 500 fluctuates more than a predetermined value, it is determined that the possibility of theft is low. .

Alternatively, CPU 110 of server 100 may determine whether the voltage of battery 501 of vehicle 500 is decreasing at a predetermined pace or higher, or may determine whether vehicle 500 is vibrating. Good. If the voltage of the battery 501 of the vehicle 500 has hardly decreased, but the vehicle 500 is moving, it is determined that there is a high possibility that the vehicle 500 has been stolen. More specifically, when the vehicle 500 is not moving, it is determined that the possibility of theft is low, and when the voltage of the battery 501 of the vehicle 500 is decreasing at a predetermined pace or more, the possibility of theft is low. Judge as low.
<Third embodiment>

  Some or all of the roles of each device of the network system 1 of the above embodiment may be executed by another device. For example, some or all of the roles of the server 100, the first terminals 200, 200,... And the second terminals 300, 300,. All may be carried by a plurality of devices.

  More specifically, as in the above embodiment, the first terminal 200 periodically uploads the measurement data to the server 100, and the server 100 executes all the theft determinations based on the measurement data. The first terminal 200 may upload measurement data to the server 100 when the first terminal 200 detects that a predetermined condition is satisfied, and the first terminal 200 may be stolen based on the measurement data received by the server 100. Sex determination may be performed. For example, when the MPU 210 of the first terminal 200 detects the vibration using the motion sensor 270, the MPU 210 may start uploading the current position information, the voltage information, and the vibration information to the server 100.

  Alternatively, the first terminal 200 may determine the possibility of theft instead of the server 100. That is, the MPU 210 of the first terminal 200 may execute the determination in step S106 of FIG. More specifically, when detecting vibration of the vehicle 500 via the motion sensor 270, the MPU 210 starts acquiring the voltage of the battery 501 of the vehicle 500 via the battery voltage monitor 290. Then, when the voltage of the battery 501 of the vehicle 500 hardly fluctuates, but the vehicle 500 is vibrating, the MPU 210 determines that the possibility that the vehicle 500 has been stolen is high. When it is determined that the vehicle 500 is stolen and carried, the MPU 210 transmits the stolen vehicle 500 to the server 100 or the second terminal 300 of the user of the vehicle 500 via the communication unit 260. Send a warning notification that you are likely to be there. At this time, it is preferable that the MPU 210 provides the server 100 and the user's second terminal 300 with the current position of the vehicle 500 and various measurement results.

  Alternatively, the MPU 210 may periodically acquire the voltage of the battery 501 of the vehicle 500 via the battery voltage monitor 290. Then, when the MPU 210 detects the vibration of the vehicle 500 via the motion sensor 270, the MPU 210 acquires the voltage of the battery 501 of the vehicle 500 again via the battery voltage monitor 290, and compares the two to obtain the battery 501. The degree of fluctuation or the degree of decrease of the voltage may be determined.

  As described in the above embodiment, the method of determining the possibility of theft can be appropriately selected.

The server 100 may be operated by a company that handles vehicle insurance, may be operated by a company that independently provides a theft notification service, or may be a manufacturer or a vehicle of the vehicle 500. It may be operated by 500 sales companies. In addition, the notification destination of the possibility of theft is not limited to the terminal of the owner or the user of the vehicle 500, but may be a server or a communication terminal of an insurance company or police.
