(Embodiment 1)
Hereinafter, the driving behavior detection in the first embodiment of the present invention will be described with reference to FIGS. The following embodiments are examples of the embodiments of the present invention, and the present invention is not limited to these embodiments. Note that in the drawings referred to in this embodiment, the same portion or a portion having a similar function is denoted by the same reference symbol or a similar reference symbol (a reference symbol simply including A, B, etc. after a number) and repeated. The description of may be omitted. Further, even if the value of data stored in the server, terminal, or the like is actually “0” or “1”, it is expressed as the meaning of the data from the viewpoint of easy understanding.

  First, as shown in FIG. 1, an accident notification system 10 in the present embodiment includes a detection device (for example, a beacon) 1 and a terminal 3. In the following, an embodiment will be described taking beacon 1 as an example of the detection device. (The beacon 201 is illustrated in FIG. 2 and the beacon 301 is illustrated in FIG. 3 as an example.)

  The beacon 1 includes an acceleration sensor 5, a communication circuit 7, and a control unit 8. The terminal 3 includes a position information detection sensor 9, a receiving device 13, and an accident determination unit 15.

  The beacon 1 is connected to a predetermined part of the vehicle (the connection is a concept including installation). The predetermined part of the vehicle is an arbitrary part as long as it is a vehicle and can communicate with the terminal 3, but a position where the button can be pressed from the driver's seat and the indicator can be visually observed is preferable. For example, it corresponds to the interior of a dashboard, a compartment, a vehicle compartment such as a handlebar, or a trunk room. Note that beacon position correction (calibration) may be performed with respect to the connection position.

  The beacon 1 is connected to the vehicle. For example, it may be connected to the vehicle by using a suction cup or tape provided on the back of the beacon (the surface on the side where the beacon is connected to some member of the vehicle is the back of the beacon), or using a screw or the like May be fixed. However, since the beacon 1 is only required to be connected to the vehicle, it does not necessarily have to have a fixing member for fixing, and does not have to be fixed.

  Of course, the beacon 1 may be mounted on a vehicle that is being manufactured, but according to the above-described configuration, the beacon 1 can be easily connected to a manufactured vehicle. Therefore, so-called retrofitting is possible even if it is not mounted during manufacture of the vehicle.

  The beacon 1 includes an acceleration sensor 5, a position information detection sensor 9, a power source (for example, a battery), an LED indicator 6 indicating a remaining power source, and a communication circuit (for example, a wireless communication circuit) as vehicle accident detection means.

  The acceleration sensor 5 (G sensor) detects a vehicle impact and is provided inside the beacon 1. Since the beacon 1 is connected to the vehicle, the acceleration of the vehicle can be measured. Note that although one beacon 1 is basically connected to one vehicle, a plurality of beacons cannot be mounted.

  The acceleration sensor 5 is preferably a three-axis acceleration sensor (for example, an X1, Y1, or Z1 axis) or a six-axis acceleration sensor (for example, an X1, Y1, Z1, X2, Y2, or Z2 axis). . The use of the uniaxial acceleration sensor and the biaxial acceleration sensor is not preferable because the acceleration when the vehicle is traveling cannot be accurately captured. In addition, since it is not possible to accurately grasp the acceleration during traveling, it is not preferable that there is a demerit that it is impossible to accurately grasp the traveling distance, speed, presence / absence of rollover, and the like.

  In addition, by incorporating a circuit for detecting the internal voltage, the LED indicator may be turned on when the remaining battery level is reduced. Since the user can know when to replace the battery, it is possible to prevent the battery from running out because of the battery.

  The wireless communication circuit uses known communication standards such as Bluetooth (registered trademark) (for example, Bluetooth Low Energy), wireless LAN (Wi-Fi, etc.), optical wireless communication (IrDA (DATA), etc.), RFID, and NFC. It may be a short-range wireless communication circuit that supports it. When the terminal 3 has a terminal for a wired connection cable, the beacon 1 may further include a wired connection unit for supporting this. Such a wired connection unit may be based on each known standard such as the USB standard and the wired LAN standard.

  The beacon 1 may be paired by transmitting a radio wave when the beacon 1 button is pressed. By pairing the beacon 1 and the terminal 3 in this way, the beacon 1 is connected to another terminal, and the accident notification system according to the embodiment of the present invention is provided to another terminal. Can be prevented.

  The power source of the beacon 1 is arbitrary and may be a solar cell, an AC power source using a dry cell, a button cell, a cigar socket, or the like. In addition, when the solar cell was used, since the beacon 1 was arrange | positioned in the position where light is irradiated, it turned out that a service life falls and it is not preferable. Therefore, a button battery or a dry battery is preferable.

  The control unit 8 of the beacon 1 controls a power supply for a load (position information detection sensor, acceleration sensor, etc.) by a predetermined trigger such as acceleration or position information.

  For example, the control unit may be a power supply unit that supplies power. Turning on the power may be that the power supply unit supplies power.

  The control unit 8 may be a program for executing the function, or an analog circuit (for example, when an acceleration exceeding the first threshold is detected, the switching element is used to energize the load. However, the present invention is not limited to this. It may be a functional block when executing a program from an external server through the terminal 3 to realize each function. The program is read and executed by a CPU (not shown).

  The position information detection sensor may be a device that grasps the latitude and longitude of the current location using GPS. For example, if a wired connection is made when the user gets on the vehicle, power can be supplied through the wired connection, and the beacon 1 can be activated only when the wired connection is made. By comprising in this way, it is also possible to selectively start the beacon 1 only at the time of boarding.

  The beacon 1 may be equipped with a search sensor that searches for the presence of a person. However, in the present embodiment, since the terminal can be paired with the beacon 1 and the wireless communication circuit, it is not necessary to mount a search sensor. That is, if the beacon is activated when the beacon 1 and the terminal 3 carried by the user M are within a certain range, the user M gets on the beacon even if the search sensor is not mounted on the beacon. It is possible to determine whether or not. The battery life of a beacon can be improved by configuring in this way and mounting a minimum function on the beacon.

  In addition, although a beacon can be equipped with a speaker that enables voice output, in the present invention, data is transmitted from the beacon 1 to the terminal 3 and the voice preset in the terminal or the data obtained from the server 20 is transmitted to the terminal 3. Therefore, it is not necessary to mount a speaker on the beacon. The battery life of a beacon can be improved by configuring in this way and mounting a minimum function on the beacon.

(Terminal 3)
The terminal 3 will be described by taking a touch panel type smartphone as an example. However, any terminal can be used as long as it is a communication terminal that can be carried by the user M of the vehicle. Mobile communication terminal devices, information processing terminal devices having communication functions and calculation functions such as personal computers are included. However, the terminal 3 needs to be equipped with an acceleration sensor and a communication function. The server 20 includes a browser or the like as a display control function for displaying a screen provided by a WEB application or an addable application, and includes a communication control unit that performs communication control between the CPU, the memory, and the server 20 ( (Not shown). Furthermore, an operation input device such as a mouse, a keyboard, and a touch panel, and a display device can be provided.

  The receiving device from which the terminal 3 receives a signal from the beacon 1 includes Bluetooth (registered trademark) (for example, Bluetooth Low Energy), wireless LAN (Wi-Fi, etc.), optical wireless communication (IrDA (DATA), etc.) It may be a short-range wireless communication circuit that supports a communication standard.

  The position information detection sensor 9 included in the terminal 3 may be a GPS. The GPS is a device for measuring the current position of an object by a technique using an artificial satellite called a global positioning system (Global Positioning System M). The GPS information measures the current position of the vehicle and outputs this current position information.

  The accident determination unit 15 provided in the mobile terminal device is provided by a native application that is installed in advance in a service providing application that can be additionally installed by a predetermined operation. The accident determination unit is a program that executes the function, but is not limited to this. It may be a functional block when executing a program from an external server to realize each function. The program is read and executed by a CPU (not shown).

  In addition, although the accident determination part is provided in the terminal 3 in FIG. 1, you may provide in a 1st detection apparatus (beacon 201) like FIG. In this case, the beacon 201 includes an acceleration sensor 205, a communication circuit 213, an accident determination unit 215 that determines whether an accident has occurred based on the first acceleration value detected by the acceleration sensor, And a transmission unit 216 that transmits the content of the message to the terminal.

  Here, the network 23 is, for example, a network for portable information terminals such as CDMA2000, 3G, and 4G, a wireless LAN, and the like, and assumes a wireless network environment. The network 23 is not particularly limited except that mobile communication is possible.

  The server 20 is configured to be able to receive data transmitted from the communication circuit of the terminal. Although not shown, the servicer may manage customer information by the server 20. The server 20 may manage contract conditions, driving conditions (past accident information), and the like.

  In the server 20, the notified terminals 30 a, 30 b, and 30 c to be connected are connected via the network 27. The notified terminal 30 is used by a servicer (insurance company, security company, etc.), and can manage and supervise the workflow from the terminal 3 via the server 20. A function for responding to a report from the user M is provided based on a predetermined workflow, and predetermined information is displayed on the screen of the notified terminal 30 so that the person in charge of the service is aware of the presence of the notification. .

  Here, the network 27 is a network such as a LAN (local area network) or the Internet, for example, and a network environment in which the user terminal 3 can connect to the server 20 regardless of a wireless / wired line, a dedicated line, or the like is applied. The

(function)
In this embodiment, in a beacon having an acceleration sensor, a communication circuit, and a control unit, power is always supplied to a portion that detects an acceleration value. This beacon may further have the above-described configuration such as a position information detection sensor.

  When the beacon 1 detects a first acceleration value that is equal to or greater than the first threshold, the control unit loads the communication circuit power supply or other load (for example, a position information sensor, a detection sensor such as a voice detection sensor, or the like). Turn on the power of By comprising in this way, a power supply can be efficiently used by supplying power to a communication circuit power supply or a position information sensor only during driving | running | working. In addition, a function for turning off the power when a predetermined time elapses after no acceleration is detected is installed. As a result, for example, if a terminal (cell phone, etc.) is put in a bag after parking and the user goes out, the beacon placed in the vehicle cannot communicate with the terminal in the bag, and the power is cut off. This saves power consumption.

  In particular, in the present invention, the acceleration sensor is not only used for starting the communication circuit of the beacon 1 and the various detection devices as described above, but when the second acceleration value is detected, the third acceleration value is set. It is important to have another function even if it is detected.

  In the present specification, a specific example of the first acceleration is an acceleration accompanying an increase in speed due to departure. As a specific example of the second acceleration, there is acceleration accompanying a decrease in speed due to sudden braking or collision with an obstacle. The unit of acceleration is represented by G.

  After the beacon 1 detects the first acceleration value equal to or greater than the first threshold value, the second acceleration value is detected. If it is greater than the second threshold value, the current acceleration value is Transmit by communication circuit. The second threshold value may be set larger than the first threshold value.

  This will be specifically described. First, the first threshold may be, for example, 0.1G to 5G, and the second threshold may be, for example, about 1G to 10G. FIG. 5 shows a table showing specific numerical values of acceleration data in the control unit. For example, if the first threshold value is 1.0 G and the second threshold value is 7.0 G, in node 1, the acceleration is 0.0 G at time 4:10, the acceleration is 0.1 G at time 4:20, and the time At 4:30, the acceleration is 1.0 G, and at time 4:40, the acceleration is 0.1 G. Then, since the acceleration is 1.0 or more at time 4:30, the first threshold value is exceeded at time 4:30. Accordingly, power is supplied to the load from this point. In node 2, the first threshold value of 1.0 G is not exceeded at any time from 4:10 to 4:40. Therefore, power is not supplied to the load. At node 3, the acceleration is 0.0 G at time 4:10, the acceleration is 1.0 G at time 4:20, the acceleration is 7.0 G at time 4:30, and the acceleration is 0.0 G at time 4:40. Then, since the acceleration is 1.0 or more at time 4:20, the first threshold value is exceeded at time 4:20. Accordingly, power is supplied to the load from time 4:20. Since the acceleration is 7.0 at the time 4:30, the second threshold value is exceeded at this point. Therefore, the acceleration data of 7.0 G is transmitted to the terminal 3 as the second acceleration. In node 4, the acceleration is 0.0 G at time 4:10, the acceleration is 0.1 G at time 4:20, the acceleration is 7.0 G at time 4:30, and the acceleration is 15.0 G at time 4:40. Then, since the acceleration is 1.0 or more at time 4:30, the first threshold value is exceeded at time 4:30. Therefore, power is supplied to the load from time 4:30. Since the acceleration is 7.0 at the time 4:30, which is the same time, the second threshold value of 7.0 G is also exceeded at this time. Therefore, the acceleration data of 7.0 G is transmitted to the terminal 3 as the second acceleration. Further, at time 4:40, the acceleration is 15.0, which exceeds the second threshold value 7.0 G. Therefore, this acceleration is also transmitted to the terminal 3. The information transmitted to the terminal 3 is the minimum acceleration information in the above, but a beacon ID may be transmitted. When the beacon ID is transmitted, as shown in FIG. 6, in addition to the acceleration value, the result of the accident determination by the accident determination unit, if there is a beacon ID and a time stamp function, there is a time and position information sensor. In such a case, position information and the like are transmitted from the terminal 3 to the server 20.

  Here, when the acceleration detected by the beacon exceeds the third threshold value equal to or greater than the second threshold value, the terminal 3 is automatically notified to the servicer (insurance company, security company, etc.). It may be set.

  Then, the second acceleration is transmitted to the terminal 3 from the communication circuit 7 of the beacon 1. The receiving device 13 of the terminal 3 receives acceleration information transmitted from the communication circuit 7 of the beacon 1. The accident determination unit 15 of the terminal 3 may determine the presence or absence of a collision using the received first acceleration information 100.

  Separately from this, the beacon 1 detects and transmits the acceleration at the second acceleration, and thereafter continues to detect the acceleration until the third acceleration exceeds the third threshold value that is larger than the second acceleration. Also good.

  Furthermore, an acceleration sensor may be mounted on the terminal 3 itself, and it may be determined whether or not it is a collision by further using fourth acceleration information that is acceleration information of the terminal itself.

  When the first acceleration value exceeds the second threshold value or the third threshold value, the voice sensor mounted on the beacon 1 or the terminal 3 can further detect a predetermined frequency generated at the time of the accident. It may be. This can be realized by creating a program to detect the frequency when the acceleration sensor exceeds a certain threshold. Whether a sound having a frequency of 1 KHz to 3 KHz, or a high frequency side (Hi side) of 480 KHz to 540 KHz and a low frequency side (Lo side) of 380 KHz to 440 KHz is extracted from a sound input from the audio sensor at a predetermined volume or more. To detect. A frequency from 1 kHz to 3 kHz is a brake sound. Moreover, the frequencies of the high sound side (Hi side) 480 KHz to 540 KHz and the low sound side (Lo side) 380 KHz to 440 KHz are horn sounds.

A flow relating to transmission of acceleration information according to an embodiment of the present invention will be described with reference to FIG. This flow is started by detecting the acceleration. First, step 101 is a step of determining whether the acceleration is equal to or greater than a first threshold value. Step 102 is a step for starting the drive mode. Step 103 is a step of transmitting a signal for starting a service providing application to the terminal 3. Step 104 is a step of determining whether the acceleration is equal to or greater than a second threshold value. Step 105 is a step of transmitting the detected acceleration value equal to or higher than the second threshold value to the terminal 3. Step 105 may be repeatedly performed (if the acceleration value is equal to or greater than the second threshold value, transmission may be continued at any time).

  First, when the beacon detects an acceleration value equal to or greater than the first threshold (step 101: YES), the beacon proceeds to step 102 for starting the drive mode. If an acceleration value equal to or greater than the first threshold is not detected, step 101 loops until it is detected.

  After starting the drive mode, the beacon 1 issues a signal for starting the service providing application to the terminal 3 (step 103). Note that step 103 may be another signal. For example, a signal for setting a mode for storing subsequent acceleration values in the memory of the terminal 3 as needed, or a mode for storing subsequent position information in the memory of the terminal 3 as needed. It may be a signal or the like.

  If the acceleration exceeds the second threshold after the transmission of the signal (step 104: YES), the acceleration information is transmitted to the terminal 3 (step 105). When it does not exceed (step 104: NO), the detection is continued until it exceeds.

  The data shown in FIG. 6 described above may be sent from the terminal 3 to the server 20. At this time, FIG. 8 shows a step of adding various information. There may be a step of confirming before sending information to the servicer (not shown).

  Step 201 is a step of determining whether or not position information can be acquired. Step 202 ′ is a step of determining whether or not position information can be acquired. Step 202 is a step of acquiring position information and adding it to the information. Step 203 is a step for determining whether time information can be acquired. Step 204 is a step of acquiring time information and adding it to the information. Step 205 is a step of adding the user name and beacon ID to the information. Step 206 is a step of transmitting information related to the accident to the server 20.

First, when the accident determination is made, the terminal 3 determines whether the position information can be acquired (step 201). If the position information can be acquired (step 201: YES), the position information is acquired and added to the information (step 202). On the other hand, if the position information cannot be acquired, it is determined in step 202 ′ whether the position information can be acquired again. At this time, a certain time may be set between step 201 and step 202 ′. If the position information cannot be acquired in step 202 ′, step 202 is skipped and the process proceeds to step 203.

  Next, it is determined whether time information can be acquired (step 203). If the time information can be acquired (step 203: YES), the time information is acquired and added to the information (step 204). If the time information cannot be acquired (step 203: NO), step 204 is skipped.

  A user name and a beacon ID are further added to the information related to the accident including the information added as described above (step 205). This information is transmitted to the server 20 (step 206).

  In the above description, the time information and the position information are given as the information regarding the accident. However, this is a typical example in the present invention, and the present invention is not limited to these. The information related to the accident and the information specifying the user transmitted when notified by the accident are mainly the date and time, the acceleration information at the time of the accident determination, and the position information at the time of the accident determination. Vehicle speed and total travel distance information calculated from the vehicle travel time and the presence or absence of a brake operation or accelerator operation calculated from the acceleration information immediately before and after the vehicle. , The user's insurance enrollment status, the user's insurer ID, name, age, and the like may be included.

(Modification)
1 to 3 show the entire system including the beacon 1. What has been described above with reference to FIG. 1 is a basic system 10. In addition, there are modifications shown in FIGS. 2 and 3, in addition to the first embodiment, additional configurations are added to the detection device and the terminal, respectively. In the modification 1 shown in FIG. 2, the case where the accident determination part 215 exists in the detection apparatus side is shown. In this case, an accident determination is performed on the beacon side, and the result is transmitted to the terminal and displayed on the terminal. In the second modification shown in FIG. 3, the position information detection sensor is mounted on the beacon side. Thereby, position information can be grasped on the beacon 301 side. Since the beacon can grasp its own location, the terminal 303 has a strong personality as a gateway to the Internet. In the second modification, the second acceleration sensor 311 is provided on the terminal side. As a result, an application in which the accident determination is performed only when the second acceleration sensor 311 of the terminal 303 and the acceleration sensor 305 of the beacon 301 are synchronized is possible.

(Embodiment 2)
A flow relating to transmission of acceleration information according to another embodiment of the present invention will be described with reference to FIGS. Since the following description will be made in accordance with the BLE standard, explanation of technical terms related to BLE will be omitted as appropriate, and the exact explanation of technical terms will be left to the standards. A description will be given by disassembling into steps S1 to S14 in FIGS. First, S1 is an operation start step. Here, when the advertisement packet of the detection device is detected, if it is a predetermined UUID (an identifier for uniquely identifying an object on the software, for example, a hexadecimal 128-bit numerical value), “in-vehicle Information such as “machine detection notification” is transmitted. At this time, the ID (for example, beacon ID) of the detection device is searched from the detection device master table using the acquired major and minor values. When the detection device ID is found, a push notification is sent and a BLE scan is performed. If the detection device ID is not found, if a detection device pairing screen is being displayed in the foreground state, a record of information relating to the detection device is registered in the detection device master table. Subsequently, in S2, BLE scanning is performed. The application on the terminal executes the following processing. First, in order to make a BLE connection to the acceleration sensor of the detection device, the following method is executed to start scanning the BLE device. At this time, information such as “scan start” is transmitted. When a device is discovered, information such as “device discovery notification” is transmitted from the transmission means in the sensor. In S3, the application on the terminal executes the following process. The detection device ID (beacon ID) is searched from the detection device master table using a predetermined value (major value, minor value) of the discovered device. If the detection device ID is found on the table, TRUE is returned as the return value of the “didDiscoverSensor method”, and BLE connection is performed. If it is not found, it is an irrelevant detection device, so FALSE is returned and BLE connection is not performed. At the same time as the BLE connection, the terminal application transmits “Notification” to the detection device, and then transmits a connection completion notification to the application. After that, the application on the terminal automatically stops scanning. In S4, traveling data acquisition is started. The detection device transmits the acceleration data measured by the acceleration sensor of the detection device at a predetermined interval (for example, every 10 seconds) and for the time within the predetermined interval (for example, data for 10 seconds). . S5 is cutting of BLE at the end of operation. When the radio wave is out of the BLE radio wave area or the “disconnect button” is selected, information such as a disconnect notification is transmitted. In S6, driving diagnosis data is acquired. In addition to collecting data on driving status for each session and storing it in the diagnostic information table for each driving operation in the storage unit of the information processing device, the accumulated data for a predetermined period (for example, daily) is recorded by overwriting every predetermined period. To do. S7 is a step of transmitting driving diagnosis data. In this step, the diagnosis result is stored in a table in the storage unit of the information processing apparatus. Furthermore, the processing can be executed for transmission to another information processing apparatus associated with the information processing apparatus. S8 is a flow that occurs in any state when the emergency button of the detection device is selected. In all states, when the emergency button is selected, the detection device stops sending a BLE connection or a normal AD packet (advertisement packet) and sends an emergency packet. S10 is a demo experience packet transmission, which is activated by pressing the emergency button for a long time in this embodiment (this allows the number of buttons to be omitted). When A second (for example, 90 seconds) elapses from S8 and S9, a standby state is set. S10 is a case where vibration is applied to the beacon (acceleration occurs). In this case, when a certain threshold G is applied, an AD packet is transmitted, and if there is no BLE connection for N seconds, the state shifts to a standby state. S11 relates to the BLE connection. When the BLE connection is established, the AD packet is stopped, and the connection is continued while the motion is detected. If N seconds (for example, 90 seconds) elapse after BLE connection cannot be established from S11, a standby state is set. S12 is a stop for a certain period of time, and when it has been stopped for B seconds (for example, 600 seconds) during BLE connection (when acceleration cannot be detected for B seconds), BLE is disconnected and a sleep state is entered. S13 is BLE disconnection, and when the BLE connection is disconnected, the detection apparatus shifts to a sleep state. S14 is a standby state, and when it has been stationary for C seconds (for example, 600 seconds) in the standby state, it shifts to the sleep state, and if it moves even a little, the standby state is maintained.

  Here, there is a problem that the advertisement packet cannot be transmitted as it is because the state shifts to the standby state after transmitting the emergency advertisement of S8. Therefore, a transmission interval extension portion that extends the transmission interval is provided, and the transmission interval extension portion can be used to extend the transmission interval for transmission. In order to solve the problem that the advertisement packet cannot be transmitted in the standby state in connection with S14 and cannot be reconnected after C seconds, C is set to A seconds or less, B seconds or less and N seconds or less. You can also.

  As described above, when the first acceleration is detected from the sleep state, the advertisement information is transmitted and the detection device is turned on and connected to the terminal, so the operation state (drive mode) is entered. Is limited to when the vehicle is moving and the terminal is (near). For example, if the first acceleration is not detected, the sleep mode is maintained, and communication is not started. If communication is not established even if advertisement information is transmitted, the standby mode is set. It also has a function of shifting to a standby mode or a sleep mode when acceleration is not detected for a predetermined time. Thus, power consumption can be reduced. In addition, the detection apparatus sends acceleration information for a predetermined time in a predetermined interval. Thereby, communication frequency can be reduced and power consumption can be reduced. In the second embodiment, the power consumption of the detection device can be further reduced as compared with the first embodiment.

(Embodiment 3)
In another embodiment, the terminal 3 may supply power to a load such as an acceleration detection sensor or a position information sensor depending on whether or not the beacon 1 exists within a predetermined range. For example, when the beacon 1 exists within 1M, the terminal 3 sends a signal to the beacon 1 to supply power to a load such as an acceleration detection sensor or a position information sensor. On the other hand, when the beacon 1 is separated from 1M, a signal is sent to the beacon 1 to stop the power supply and enter the sleep mode. In this case, the terminal 3 always scans for the presence of the paired terminal 3 around it. The scanning range may be wider than the predetermined range described above.

  The period that the terminal 3 scans may be changed based on the position and the actual first detection device that is present. For example, when it is detected that the terminal 3 is in an estimated low-frequency area (supermarket, shopping mall, home, etc.), the first detection device is scanned because the possibility of getting into the car is low. The speed may be slow (at least frequent).

  Thus, the scan mode may be changed according to the position information of the terminal 3. For example, when in a shopping mall, the scan speed may be changed to a slow mode such as 5 second scan, 1 minute pause, or 10 second scan, 2 minute pause. For example, the acquisition frequency may be 10 Hz, the transmission frequency may be every 10 seconds, or the like.

  Conversely, the beacon 1 may always detect whether the terminal 3 is in the communication prefecture. Also in this case, the number of scans may be reduced in the case of the estimated low frequency area. In this case, first, the beacon 1 sends a packet. Terminal 3 receives the packet and responds by sending a scan request. At this time, the beacon 1 measures the strength of the signal RSSI, and if the signal strength is equal to or lower than the specified level, the beacon 1 determines that the terminal 3 exists far away, and the beacon 1 ignores the terminal 3. On the other hand, when the terminal 3 is nearby, the beacon 1 is switched from the RSSI detection mode to the packet reception mode.

  At this time, the packet information transmitted every X seconds in the scan of the terminal 3 or the beacon 1 may include a synchronization packet. As the synchronization packet, time information, an encryption key, a terminal-specific identification number, a beacon-specific An identification number or the like may be included.

(Additional functions)
The terminal can also connect to the Internet via a cellular data communication network and obtain synchronization information regarding the beacon 1 from a secure cloud server protected by an authentication key and an encryption key. In a further embodiment, the terminal may function as a gateway to the Internet to download beacon 1 firmware updates and may send diagnostic information regarding the function of the beacon 1 to the server. . Thereby, even if it does not equip the beacon 1 with a wide area communication function, it can communicate using the terminal 3 as a gateway.

  Furthermore, the beacon 1 can be calibrated. For example, RSSI may be used for the calibration function. RSSI is a circuit or signal for measuring the strength of a signal received by a wireless communication device, and the distance can be estimated from the sensitivity level. By comparing and contrasting this with the actual distance, the approximate distance between the first detection device and the terminal 3 can be calculated. However, since this is based on the signal quality, the signal may be interfered depending on the type of the terminal 3, the presence or absence of a person or object to be blocked, the weather, etc., and is not perfect.

(Use as a key)
When communication between the terminal 3 and the server 20 is performed, the terminal 3 and the beacon 1 are paired without being input with a user name and a personal identification key. By using the existing encryption key, it is possible to communicate with the server 20 securely.

  The beacon 1 basically consumes electricity when transmitting and receiving. Bluetooth (R) consumes more power when receiving rather than transmitting.

Example 1
User M attaches beacon 1A to automobile C. Since the LED indicator would not be visible on the glove box and could slide off when placed on the dashboard, it was connected to the dashboard using a suction cup.

  The beacon 1 is equipped with a control unit, an acceleration sensor, a wireless communication circuit, and a button battery, and each has a function as described in the first embodiment.

  In the present embodiment, the LED indicator is lit when the remaining battery level is reduced. About this LED indicator, the lighting state of LED changes for every starting mode.

  The terminal of the user M includes an acceleration sensor, a wireless communication circuit, a touch panel liquid crystal display as an input device, a CPU, a memory, a speaker, a power supply, a GPS, a time stamp function, and the like.

  The user M is paired using the service providing application in which the terminal 3A and the beacon 1A are pre-installed in the terminal 3A that he / she owns.

  First, when the user M gets into the car C equipped with the beacon 1A and departs, the beacon 1A detects the acceleration at the time of departure and automatically activates the drive mode. At this time, since the start information is transmitted from the beacon 1A to the user's terminal 3A, a service providing application that is installed in advance and provides the service described in the present embodiment is launched, and the user's terminal 3A automatically enters the drive mode. The service providing application enters the drive mode, and the service providing application starts recording the running data.

  By detecting the acceleration at the time of departure and setting to automatically activate the drive mode, when the vehicle departs, the service provision application is activated, and the fact that the service provision application has been activated is displayed on the screen of the terminal 3A, for example, “App Is now in drive mode. Enjoy safe driving today. " As you can see, if you accelerate, detection starts automatically, so you don't have to forget to turn on the switch and the battery lasts longer.

  When the acceleration sensor of the beacon 1A senses an impact of 7G or more, the information that the beacon 1A automatically senses the impact is transmitted to the terminal 3A. The terminal 3A transmits information indicating that an impact has been detected, position information, and time information to the server 20. At this time, the terminal 3A also transmits an alert that a collision has been detected. The alert includes the insured person name, the insured person ID, the position information of the place where the collision is detected, the time when the collision is detected, and the value of the acceleration sensor.

  A text message (SMS) is sent to the driver's smartphone. The message is, “A car in which Mr. M is on board has just sensed an impact near Iwata at 4:40. Is it safe? Mr. M responds to this message within a specified time (eg, 60 seconds). If you don't receive the call, we will call you, or you can call the number directly from User M. The message is "03-XXXX-XXXX". In the following, the servicer's telephone number is expressed as 03-XXXX-XXXX.

  If there is no response to the SMS message within a predetermined time (for example, 60 seconds), the response confirmation unit determines that a response by telephone is necessary. This allows the insurance company to avoid making calls when it is not needed, and to minimize making direct calls. In addition, when the user M first wants to contact the police or the fire department, the user M has only to respond so that he / she does not receive a telephone call from the servicer, which has the effect of reducing the troublesomeness of the user.

  If there is no response on the phone, enter “no phone response” into the system. Then, the message sending part of the server said, “M-sama, is it safe? I just called you, but there was no reply. A response confirmation message (SMS) is sent, such as “Contact within an hour (for example, 60 seconds) and the emergency member will rush to the scene.”

  In response to this, if there is no response within a predetermined time (for example, 60 seconds), the insurance company arranges an ambulance, and if necessary, the police, the security company, etc. are notified of the user's last location information (location where the collision was detected). Position information). When making an arrangement, enter “arranged” in the system, and the server's message sending section will send a message to the user such as “M, now the emergency service is going to the user M” (SMS ).

  When personnel rush to arrange emergency services by the servicer, the terminal 3 may be notified of the rushing service personnel and arrival time. For example, an application notification and a map may be displayed indicating who will be in what car and when. By configuring in this way, the user M can know what person will come in what car and by what time, so it is possible to prevent fraud due to impersonation of emergency services.

  Depending on the type of the terminal 3, the above notification or the text message may be used instead of the pop-up. The terminal type may be confirmed by the service providing application confirming the model information, or the WEB application may acquire the terminal type through the WEB browser.

  When personnel arrive at the emergency service, the safety 31 is confirmed by the terminal 31 possessed by the personnel, and if the safety is entered, a flag of end F (Finish) is entered in the express workflow.

  As described above, in the system 10A according to the embodiment of the present invention, it is possible to accurately determine the presence or absence of an accident because the accident determination is performed using both the acceleration sensors of the beacon 1A and the terminal 3A.

  In addition, when accessed (or when the app is started), the date and time of the accident, weather, traveling speed, and location are automatically entered, so the contents of the accident can be accurately grasped.

  ADVANTAGE OF THE INVENTION According to this invention, an accident report can be performed simply and cheaply, and an energy-saving detector, an accident report system, an accident report method, and an accident report program can be provided. Furthermore, it is possible to report from outside the vehicle by using a smartphone. In one embodiment, the servicer can accurately grasp the accident information.
