Japanese Unexamined Patent Publication No. 2020-149433

One of the purposes is to provide a technology different from the conventional vehicle monitoring. For example, conventional monitoring while parking is one of the purposes of controlling mischief, theft, etc. of the vehicle, for example, preventing children from being misplaced in the vehicle or children trapped in the vehicle. Problems such as controlling the occurrence of accidents such as heat stroke cannot be solved.

The above-mentioned problems are described as independent, and the present invention does not necessarily have to be able to solve all of the described problems. The object of the invention of the present application is not limited to this, and the intention is to acquire the right of the configuration for the purpose of obtaining the effect of the configuration disclosed in the present specification, drawings, etc. by divisional application, amendment, or the like. .. For example, the present specification discloses a problem in which the part described as "can be" is replaced with "is a problem" in the present specification. The issues are described as independent, and we intend to independently acquire the rights to the structure for solving this issue by divisional application, amendment, etc. Even if the subject matter is implicitly grasped from the description in the specification, the applicant intends to make a part of the structure described in the specification amended or to make the claims in the divisional application. It also discloses issues that combine these independent issues.

The following is an example of a means for solving a conventional vehicle monitoring problem.

(1) It is preferable to use a system having a detection function for detecting the state of the vehicle interior of a parked and / or stopped vehicle and an output function for outputting predetermined information based on the detection result. By doing so, predetermined information based on the state of the vehicle interior is output, so that the state of the vehicle interior can be known. The output function may be, for example, directly notified by the system or transmitted by communicating with the outside. The predetermined information may be, for example, the detection result itself, the information used for detection, other information, and the like.

(2) The state of the vehicle interior detected by the detection function may be whether or not a person is present on the rear seat side of the vehicle. By doing so, for example, when a person is present in the backseat, a predetermined output is produced, so that the driver can know that there is a person in the backseat, for example, the occurrence of misplacement of a child. Can be prevented. Further, even when a child or the like is left in the vehicle, it can be confirmed that the child is in the vehicle, so that it is possible to prevent an accident from occurring, for example, returning to the vehicle early.

(3) The state of the vehicle interior detected by the detection function may be whether or not a person is present in the child seat installed in the vehicle. By doing so, for example, when a child is present in the child seat, a predetermined output is produced, so that the driver can know that the child seat has a child, and for example, the occurrence of misplacement of the child is prevented. be able to. Further, even when a child or the like is left in the vehicle, it can be confirmed that the child is in the vehicle, so that it is possible to prevent an accident from occurring, for example, returning to the vehicle early.

(4) It is preferable to have a function of performing image analysis on an image acquired from the rear seat side of the vehicle or a means for photographing the child seat and analyzing whether or not there is a person in the image. By doing so, it is good that the existence of a person can be surely known by image analysis. If the image analysis is performed by the image processing circuit (edge side) installed in the vehicle, the amount of communication data to be performed after the analysis can be reduced.

(5) When the image analysis is performed and the presence of a person is detected in the image, the output function may send the detection result without sending the image. In this way, when a person is detected, the detection result is sent, but since the image data is not transmitted, it can be notified quickly and the amount of communication data can be reduced.

(6) The state of the vehicle interior detected by the detection function may be the presence or absence of an object moving in the vehicle interior. Since the object moving in the vehicle interior is, for example, a person or an animal, the driver or the like can know that the object exists and can prevent the object from being left behind in the vehicle.

(7) The detection function acquires a sound heard in the vehicle interior and detects a dangerous state from the acquired sound, and the output function externally detects the dangerous state when the dangerous state is detected. It is good to communicate and inform. By doing so, for example, a driver or the like who is away from the vehicle can know that the vehicle is in a dangerous state. As a result, the driver or the like can quickly return to the vehicle. The sounds that can be heard in the passenger compartment include, for example, the sounds that are generated in the passenger compartment, such as the voices of the people remaining in the passenger compartment, the sounds that are generated from the vehicle, and the sounds that are heard in the passenger compartment. ..

(8) The detection function may detect a dangerous state based on the temperature inside the vehicle interior, and the output function may notify the outside by communicating when the dangerous state is detected. .. By doing so, for example, a driver or the like who is away from the vehicle can know that the vehicle is in a dangerous state. As a result, the driver or the like can quickly return to the vehicle.

(9) The detection function shall detect a dangerous state based on the temperature inside the vehicle interior.
The output function may prevent the predetermined information from being communicated to the outside when the dangerous state is not detected. By doing so, for example, when the driver intentionally puts a child or the like in the vehicle, the notification is not given if the temperature inside the vehicle is not dangerous, so that the annoyance of unnecessary notification is eliminated. , You will not be able to be notified. Therefore, for example, necessary information can be notified when necessary.

(10) The predetermined information may be the detection result. By doing so, the driver or the like can know the state of the vehicle interior based on the detection result.

(11) The detection function may detect the state of the vehicle interior based on the output of the seating sensor provided on the child seat installed in the vehicle. By doing so, the presence or absence of a child can be reliably detected, and an appropriate output can be performed based on the detection.

(12) It is preferable that the output function outputs an alarm when the driver gets off with a means for detecting the driver's movement and a person is present in the child seat. By doing so, the driver can confirm that a person (for example, a child) is present in the child seat at the time of getting off, prevent the occurrence of an unintended misplacement, and temporarily leave a child or the like in the car. By getting off the train knowing that, it is possible to prevent accidents such as returning in a short time.

(13) When a person is present in the child seat, it is preferable to have a function of preventing the door of the vehicle from being locked. By doing so, it is possible to suppress the occurrence of a situation in which a child or the like is left in a state of being trapped in the vehicle.

(14) When a person is present in the child seat, when the door of the vehicle is locked, a function of notifying the presence of a person and preventing the lock from being locked, and a function thereof. If the lock operation is performed after the notification is performed, it may be locked. By doing so, the presence of a person on the child seat is notified along with the lock operation, so that it is possible to prevent an unintended misplacement of a child or the like in the vehicle, and further, the child or the like is intentionally left in the vehicle. In some cases, the door of the vehicle can be locked.

(15) The detection function detects the temperature in the vehicle interior, and the output function transmits the temperature in the vehicle interior to a predetermined communication destination when the condition is satisfied. It is preferable to have a function of changing the state of the vehicle interior by remote control of the vehicle from a terminal of a predetermined communication destination.

By doing so, for example, whether or not the passenger compartment has a high temperature that may cause heat stroke, or a low temperature that may cause hypothermia, etc., by appropriately setting the conditions. Or, you can know the state just before those dangerous states. Then, the driver may return to the vehicle, for example, and quickly take measures to avoid those dangerous situations. Further, the state of the vehicle interior can be changed by remote control of the vehicle from the terminal of the communication destination, and for example, it may be possible to avoid the vehicle interior from becoming a dangerous state more quickly.

(16) The detection function may have a function of photographing the vehicle interior, and the output function may transmit the photographed image to a predetermined communication destination. By doing so, a user such as a driver who is away from the vehicle can know the state of the inside of the vehicle, can appropriately determine whether or not it is necessary to return to the vehicle, and act accordingly.

(17) Each of the above functions may be configured by a drive recorder.

(18) A smart band attached to a child's foot or arm to detect the child's ecological information is provided, and the state of the vehicle interior detected by the detection function is the ecological information of the child in the vehicle interior.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to illustrate the technical features that may be employed in the present invention. The configuration, shape, etc. of the apparatus described are merely explanatory examples, and the present invention is not construed as being limited thereto, and is based on the knowledge of those skilled in the art as long as it does not deviate from the scope of the present invention. , Various changes, corrections and improvements can be made. In the following description, labeling using the first and second numerical values is for identifying each element, and does not determine the number of elements.

[Background to the idea of the invention of the present application]
The use of child seats is compulsory when driving an infant under the age of 6 in a vehicle. In addition, even children over the age of 6 are recommended to use child seats according to their growth until they reach a height of 140 cm, which is the height that a vehicle seat belt can be worn. There is a type of this child seat that is installed in the back seat of the vehicle. For example, a child sitting in a child seat is left behind in a car, and an accident such as heat stroke of a child trapped in the car has become a social problem. The cause of the accident is, for example, when the driver forgets the existence of the child sitting in the child seat and gets off as it is, even if he / she is aware of the existence of the child, when he / she sees the child when getting off. When I'm sleeping, I feel sorry for waking up, for example, when I get off the train because I think "it's okay if it's time to shop" or "it's okay because I'll be back soon", and so on. Be done. Also, considering the child remaining in the vehicle, if the air conditioner is operated with the engine running and the vehicle gets off, the air conditioner may stop due to the engine turning off for some reason. There is a risk that the temperature of the air conditioner will rise and children in the vehicle will be at risk of heat stroke. Regardless of the presence or absence of a child seat, for example, the driver is scheduled to return immediately, and the same situation will occur if it takes longer than planned to get off the vehicle with children etc. in the vehicle and return to the vehicle. There is. In addition, the accident that occurs when a child is left in a parked vehicle is not limited to the heat stroke caused by the above-mentioned increase in the temperature inside the vehicle, and is not limited to the heat stroke caused by the decrease in the temperature inside the vehicle in winter, for example. There is also hypothermia. The following embodiments are examples of embodiments for solving such problems.

[Basic configuration of one embodiment of the system]
1 and 2 show a preferred embodiment of the system. The system of this embodiment includes a drive recorder 10 which is an aspect of an electronic device and an in-vehicle device, and a power supply device 30 and the like for supplying power to the drive recorder 10. By receiving the power supply from the power supply device 30, the drive recorder 10 can operate for a predetermined period of time even when the engine or the like is off, for example, while parking. Further, the drive recorder 10 alone constitutes an embodiment of the system of the present application.

In the present embodiment, the drive recorder 10 is a device installed later with respect to the vehicle 1. The drive recorder 10 is attached, for example, at a predetermined position above the windshield 2 of the vehicle 1 or at an appropriate position such as on the dashboard. In the illustrated example, the vehicle 1 has a child seat 4 installed in the rear seat 3. The child seat 4 is, for example, an auxiliary device for infants, and includes, for example, a child seat for babies (also referred to as a baby seat), a child seat for infants, a child seat for school children (also referred to as a junior seat), and the like.

The power supply device 30 is a device that is interposed between the vehicle and the drive recorder 10 to supply power to the drive recorder 10. The power supply device 30 is composed of a housing different from the drive recorder 10. The power supply device 30 includes a charge / discharge control unit 30a, a DC-DC converter 30b, a CPU 30c, an internal battery 30d, and the like. The charge / discharge control unit 30a controls charging of the internal battery 30d and power supply to the drive recorder 10. The internal battery 30d is a secondary battery, and is realized by, for example, a nickel hydrogen rechargeable battery. The DC-DC converter 30b converts the voltage of 12V or 24V supplied from the battery of the vehicle into a voltage of 5V and outputs the voltage via the charge / discharge control unit 30a. The CPU 30c uses a memory (for example, RAM) (not shown) as a work area to control each part of the power supply device 30 such as the charge / discharge control unit 30a. Further, the CPU 30c communicates with the drive recorder 10 connected via the cable 5. The cable 5 includes a power supply line and a communication line.

The charge / discharge control unit 30a receives power from the internal battery 30d. The charge / discharge control unit 30a controls the power supply path so as to supply power from the vehicle battery to the internal battery 30d and the DC-DC converter 30b while the power is being supplied from the vehicle battery. As a result, the internal battery 30d is charged, and the DC-DC converter 30b supplies the voltage-converted electric power to the drive recorder 10. The charge / discharge control unit 30a determines ON / OFF of the ACC of the vehicle and switches whether to charge or discharge the internal battery 30d. When the charge / discharge control unit 30a determines that the ACC is ON, the charge / discharge control unit 30a controls to supply power from the vehicle battery to the internal battery 30d and the DC-DC converter 30b. When the charge / discharge control unit 30a determines that the ACC is OFF, the charge / discharge control unit 30a controls to discharge the internal battery 30d and supply power from the internal battery 30d to the DC-DC converter 30b.

As described above, the power supply device 30 receives power from the vehicle battery and outputs electric power to the drive recorder 10 during the period when the ACC is ON. When the power supply from the vehicle battery is cut off, the electric power is output to the drive recorder 10 using the internal battery 30d for a specified time after the cutoff. After the specified time has elapsed, the power output is turned off. When the supply of electric power from the vehicle battery is resumed, the electric power is output to the drive recorder 10 again using the vehicle battery.

As a result, the drive recorder 10 can continue to operate for a specified time after the ACC is turned off and the power supply from the battery of the vehicle is cut off. The specified time may be set, for example, by serial communication from the drive recorder 10. When the drive recorder 10 receives the battery switching signal from the power supply device 30, it transmits a signal instructing a predetermined time. The CPU 30c may set a specified time set value included in a signal for instructing a specified time to be received as a specified time.

Further, it is preferable that the power supply device 30 is provided with a DIP switch or other operation unit to have a function of setting a specified time. By doing so, for example, even a drive recorder having no communication function can be supplied with power until a predetermined time elapses after the supply by the vehicle battery is cut off.

When the power supply from the vehicle battery is cut off, the power supply device 30 switches the power supply source to the internal battery 30d and supplies power to the drive recorder 10. Since the drive recorder 10 continues to be supplied with power before and after the switching, the drive recorder 10 cannot determine whether the power supply source is the vehicle battery or the internal battery 30d. Therefore, when the power supply source is switched to the internal battery 30d, the CPU 30c transmits a battery switching signal to the drive recorder 10. If the ACC is turned on after the power supply device 30 turns off the output after the specified time has elapsed, the drive recorder 10 restarts the power supply that has been stopped, so that it can be determined that the ACC has been turned on. .. On the other hand, when the ACC is turned on within the specified time, the drive recorder 10 continues to be supplied with power, so it cannot be determined whether the power supply source is the vehicle battery or the internal battery 30d. Therefore, when the ACC is turned on within the specified time, the CPU 30c transmits a vehicle switching signal notifying that the power supply source has been switched to the battery of the vehicle. As a result, the drive recorder 10 can recognize that the ACC is turned on and the power supply source is switched to the battery of the vehicle. The drive recorder 10 may switch the operation mode according to the input of the battery switching signal and the vehicle switching signal.

The drive recorder 10 has a function of capturing a predetermined area with a camera which is a shooting device, a function of generating the captured image and other data, a function of outputting the generated data, and the like. The data output includes an output for recording the data in the storage area, an output (that is, transmission) of the data by communication, an output to an external device via the data output terminal, and the like. Further, the predetermined area photographed by the drive recorder 10 of the present embodiment may be, for example, an indoor area including a front area of the vehicle and a child seat 4 in the vehicle interior. In this way, the cameras for photographing the front area and the indoor area are provided with, for example, a plurality of cameras so that the field of view of each camera faces the direction of each area, for example, a 360 ° camera or a larger angle of view. It is preferable to use one camera to take a picture of the front and the inside of the vehicle, and in particular, it is good to use a plurality of cameras because the area including the child seat can be taken with high accuracy.

The drive recorder 10 includes a camera 11, a microphone 12, an abnormality detection sensor 13, a GPS module 14, an operation unit 15, a control unit 16, a temporary storage memory 17, a monitor 18, a speaker 19, a memory card slot 20, a microwave sensor 22, and a temperature. It includes a humidity sensor 23, a communication unit 24, and the like. The camera 11 is provided with one or a plurality of cameras, and captures a predetermined area such as the front of the vehicle and a predetermined area in the vehicle interior. The microphone 12 collects, for example, ambient sounds. The microphone 12 collects, for example, the voice of a person riding in a vehicle, other sounds generated in the vehicle interior, and the impact sound when an object collides with the vehicle. The abnormality detection sensor 13 is, for example, an acceleration sensor or a 6-axis sensor (3-axis acceleration, 3-axis angular velocity integrated type), and detects a vehicle state such as an impact applied to the vehicle, vehicle acceleration, and tilt.

The control unit 16 estimates that an accident (collision) has occurred when the detected value of the abnormality detection sensor 13 exceeds a threshold value or, for example, shows a predetermined temporal change indicating that an impact has occurred. In addition to the occurrence of an accident, the control unit 16 may be used to detect driving conditions such as sudden braking / sudden steering, sudden start, and sudden braking, and to record the history thereof.

The GPS module 14 receives GPS signals based on positioning. GPS is an example of a global navigation satellite system (GNSS), which is a satellite positioning system. Positioning by GNSS is generally used as GPS positioning. GPS signals are signals that can be received from GPS satellites. The GPS module 14 obtains the position information (longitude, latitude) of the current position from the received GPS signal by an original algorithm. The control unit 16 may acquire the position information output from the GPS module 14 at regular intervals (for example, every second).

The operation unit 15 is a button that gives various instructions to the control unit 16, and has, for example, a function of giving a recording start instruction. When the operation unit 15 is pressed, the control unit 16 may perform event recording to start recording the image taken by the camera 11 and the sound collected by the microphone 12. Further, the operation unit 15 may have a function of giving a recording stop instruction. The recording start instruction and the recording stop instruction may be different buttons for giving each instruction, for example, but may be performed by different operations on the same button. By doing so, the number of buttons installed can be reduced, and the drive recorder 10 can be downsized.

The temporary storage memory 17 is, for example, a RAM that temporarily stores video data or the like captured by the camera 11. The control unit 16 constantly stores video data and the like captured at least from the present to the past for a certain period of time or more. Since the storage capacity is finite, the control unit 16 deletes old video data and the like based on a certain standard. A certain standard may be, for example, a video data stored a certain time or more before, or a case where the memory capacity to be stored becomes a certain amount or more. In the present embodiment, the temporary storage memory 17 may be configured by, for example, a ring buffer.

The monitor 18 is a display unit that displays an image. The control unit 16 displays, for example, video data captured by the camera 11 on the monitor 18 in real time. The speaker 19 outputs sound. The control unit 16 outputs a predetermined sound from the speaker 19 at a predetermined recording time, an alarm time, an operation time, or the like. For example, the control unit 16 notifies the operation sound of the operation unit 15 and various messages (guides, alarms, etc.) by using the speaker 19.

The memory card slot 20 can be attached to and detached from, for example, a micro SD card 21. When the micro SD card 21 is attached, the control unit 16 reads / writes data to / from the micro SD card 21. The micro SD card 21 is a storage medium on which data such as video and location information is recorded by the drive recorder 10. The micro SD card 21 is an external storage means that can be attached to and detached from the memory card slot 20, but is used in place of or in combination with the internal storage means (for example, a hard disk or EEPROM) of the drive recorder 10 or other storage means. May be done. However, if the drive recorder 10 makes it possible to access a system capable of recording data without using an environment accessible to an unspecified number of people (for example, a cloud computing environment), the data stored in the storage means. It is desirable to protect the environment.

The microwave sensor 22 detects, for example, the movement of an object in the vehicle, and may, for example, detect the movement of an object (for example, a person) on the rear seat 3 or the child seat 4. The temperature / humidity sensor 23 detects the temperature and humidity in the vehicle interior. The communication unit 24 may use, for example, an LTE-M module capable of LTE (Long Term Evolution) communication.

The control unit 16 is a microcomputer equipped with a CPU, ROM, RAM, non-volatile memory, I / O, etc., and has the above-mentioned various input devices (camera 11, microphone 12, abnormality detection sensor 13, GPS module 14, operation unit 15). , Temporary storage memory 17, memory card slot 20, microwave sensor 22, temperature / humidity sensor 23, etc.) to execute predetermined processing based on the information input, and output devices (temporary storage memory 17, monitor 18, speaker 19, etc.) The predetermined information is output by using the memory card slot 20, the communication unit 24, etc.). The function of the drive recorder 10 is stored in the EEPROM of the control unit 16 as a program executed by the computer included in the control unit 16, and is realized by the computer having the control unit 16 executing the program. As a function realized by the computer by the program possessed by the control unit 16, it has a function of performing various controls in the drive recorder 10. The control unit 16 has, for example, a function of recording data such as video and information about a position, a function of outputting data, and a function of displaying an image (video).

The control unit 16 is a circuit for realizing the basic functions of the drive recorder 10, and stores the video data captured by the camera 11 in the temporary storage memory 17 as a video file, a detection signal from the abnormality detection sensor 13 and the like. Based on the pressing of the operation unit 15, the above-mentioned captured video file is stored in the non-volatile memory. In the present embodiment, the micro SD card 21 installed in the memory card slot 20 is used as the non-volatile memory. By removing the micro SD card 21 and attaching it to a memory card reader or the like connected to a personal computer, data can be taken into the personal computer and the video file can be played back using a viewer installed in the personal computer. Further, the recorded video or the like is not limited to the micro SD card 21 attached / detached and taken out to the outside as described above, but may be performed by data transmission by wire communication or wireless communication. Further, in order to perform wired communication, it is preferable that the main body of the drive recorder 10 is provided with a connector for connecting a communication cable, USB, or the like.

The function of recording this video data (recording function) will be described in more detail. For example, when the engine-started ACC is ON, the camera 11 constantly captures, for example, the surrounding conditions of the own vehicle. Then, the control unit 16 stores, for example, the video data captured by the camera 11 in a temporary storage memory 17 such as a ring buffer. The video stored in the temporary storage memory 17 is sequentially updated to the latest one, and the past video data is retained for a set time.

Then, for example, when the output value of the abnormality detection sensor 13 exceeds the threshold value or shows a predetermined temporal change in the impact generated at the time of an accident, sudden braking, or sudden steering, the control unit 16 is before the impact detection time. The video data for a certain period of time is read from the temporary storage memory 17 and stored in a non-volatile memory, for example, the micro SD card 21, and after the time when the threshold value is exceeded, the image of the camera 11 captured thereafter is stored in the micro SD card 21. Recording is performed directly or via the temporary storage memory 17. As a result, the images for a predetermined time before and after the impact are stored in the micro SD card 21 which is a non-volatile memory. At this time, the control unit 16 also records the surrounding sound collected by the microphone 12 in association with the video data. The control unit 16 also temporarily stores this recording in the temporary storage memory 17, and when the video data is stored in the micro SD card 21, the recorded audio data is also stored in the micro SD card 21.

The storage of data in the micro SD card 21 in the drive recorder 10 is not limited to the one triggered by the detection signal of the abnormality detection sensor 13 as described above. The control unit 16 may have, for example, a function that is triggered by pressing the operation unit 15. In this way, video recording can be performed when a situation occurs in which the user wants to record.

Further, recording to the micro SD card 21 is not limited to the event recording mode performed when an accident or the like based on the output of the abnormality detection sensor 13 occurs or when the recording start condition is satisfied such as pressing the operation unit 15. For example, it is preferable to provide a continuous recording mode for recording to the micro SD card 21 from the time the drive recorder 10 is turned on to the time the drive recorder 10 is turned off. The continuous recording mode is a mode for performing continuous recording, which is an example of recording other than event recording. When the continuous recording mode is provided, the control unit 16 records the recording destination of the video data output from the camera 11 and the sound data output from the microphone 12 directly on the micro SD card 21 instead of the temporary storage memory 17. It is good to set it to. By recording directly to the micro SD card 21 in this way, the process of writing to the temporary storage memory 17 once becomes unnecessary.

Further, when the video data or the like is directly written to the micro SD card 21 and the continuous recording mode and the event recording mode are provided, the control unit 16 satisfies the event recording start condition when the event recording start condition is satisfied. As the data of the past section from time to time, it is advisable to use the data recorded as continuous recording. Then, in the event recording, the control unit 16 may record, for example, as a file different from the file for continuous recording. The event recording mode is a mode for recording an event. Event recording is recording performed when a predetermined event (an example of an event) occurs. Event recording is performed when a predetermined event occurs even if the user does not explicitly instruct to start recording.

While the vehicle is parked with the engine stopped (ACC turned off), it is preferable to operate in the parking monitoring mode and record the video data or the like taken by the camera 11 in the micro SD card 21 according to the set operating conditions. The recording in the parking monitoring mode is the same as when the ACC is ON, for example, when the image taken at a predetermined recording time (for example, 30 minutes) is constantly recorded, or when an abnormality is detected by the abnormality detection sensor 13. , It is preferable to provide event recording or the like for continuously recording video data for a predetermined time. Event recording includes, for example, "detecting that a person or vehicle is approaching", "detecting an impact above a certain level", "detecting an inclination of a vehicle above a certain level (for example, jacking up)", and "opening the vehicle door". Performed when event conditions such as "detection" are met. The abnormality detection sensor 13 includes one or a plurality of sensors for detecting them.

[Dangerous condition notification / avoidance function in the vehicle interior]
The drive recorder 10 has a function of notifying a driver or the like or performing a predetermined danger avoidance process when a dangerous state occurs in the vehicle interior while the vehicle is stopped or parked. .. Dangerous conditions include, for example, misplacement of children and the like in the vehicle, and conditions in which the children remaining in the vehicle may cause a life-threatening condition such as heat stroke. Then, when the drive recorder 10 receives the battery switching signal from the power supply device 30 (ACC is OFF), the drive recorder 10 switches to a monitoring mode for monitoring the presence or absence of a dangerous state in the vehicle interior, and the control unit 16 performs the following processing.

* Image-based detection The control unit 16 has an image analysis function for analyzing whether or not a person is shown in the image to be processed. When the mode is switched to the monitoring mode, the image captured by the camera 11 that captures the area including the child seat 4 is acquired, image analysis is performed, and the presence or absence of a person is determined. When a person is detected in the image, the control unit 16 transmits predetermined information to the registered destination using the communication unit 24. The predetermined information may be the presence notification of the existence of a child, the acquired image, the temperature information and humidity information in the vehicle interior acquired from the temperature / humidity sensor 23, the position information acquired from the GPS module 14, and the like. If only the recognition result is used without sending the image, the amount of communication can be reduced and the notification can be promptly performed. Further, the image analysis may be processed by software, but for example, a chip having an image recognition function and having a function of sending only the recognition result to the server without sending the image is preferable.

The registered destination may be, for example, a server 32 such as a cloud server, or a driver's smartphone 33. The server 32 stores the information of the drive recorder 10 and the destination of the user in association with each other, and when a predetermined information is sent from the drive recorder 10, the server 32 stores the received information and all or all of the acquired information. Send a part to the destination of the associated user. As a result, for example, when the ACC is turned off to park or stop the vehicle, if the child is sitting on the child seat 4, the driver's smartphone 33 or the like is notified directly or via the server 32. As a result, the driver can be aware of the existence of the child again, and can suppress as much as possible the possibility that the driver forgets the existence of the child sitting in the child seat 4 and gets off as it is. In addition, even if the child is left in the car for some reason, if the child's existence is noticed, for example, the engine is restarted to turn on the air conditioner, or the child returns to the vehicle as soon as possible. It is possible to prevent the child remaining in the vehicle from suffering from heat stroke as much as possible.

When the destination of the drive recorder 10 is the server 32, access information to the server 32 can be registered in advance at the time of shipment of the drive recorder 10, for example, and a user who has purchased the drive recorder 10 can use the drive recorder 10. It is not necessary to register the destination such as the user's telephone number or address. The drive recorder 10 is, for example, small in size, and in the installed state, it may be hidden behind the rearview mirror at a predetermined position above the windshield, for example, and it is difficult to perform operations such as mode setting. This is good because the processing for the drive recorder 10 for the purpose is not required. Then, the user can receive the notification via the server, for example, by accessing the server 32 and registering the information of the smartphone or the like to be notified in the server 32. The access and registration process to the server 32 may be relatively easy.

Further, even after the above transmission is performed, the control unit 16 acquires an image taken by the camera 11 at an appropriate timing, performs image analysis, and determines the presence or absence of a person. Then, when a person is detected in the image, the control unit 16 transmits predetermined information to the registered destination using the communication unit 24. The predetermined timing may be in the order of "minutes" such as several minutes to ten and several minutes. By being notified that there is a child in the vehicle on a regular basis, it is good to remember the existence of the child and to give an opportunity to return to the vehicle early.

Further, it is preferable that the predetermined information is not only the recognition result but also the image taken by the camera, the temperature information and the humidity information detected by the temperature / humidity sensor 23, and the like. In this way, when the vehicle gets off with a child left, the condition inside the vehicle is periodically sent to the driver's mobile terminal such as the smartphone 33, so that the vehicle returns to the vehicle when something happens. It is good because it can prevent the occurrence of accidents. For example, if an image taken by the camera 11 is sent as predetermined information, it is possible to know that the child has awakened when he / she goes in the vehicle because he / she was asleep at the time of getting off, and immediately returns to the vehicle. It is good because it will be an opportunity for you. In addition, if temperature information, humidity information, etc. are used as predetermined information, a driver or the like who is away from the vehicle can know the temperature change or humidity change such as temperature rise or temperature drop at an early stage, and heat stroke. It is possible to return to the vehicle and deal with it before it becomes a dangerous environment that causes hypothermia.

On the other hand, the control unit 16 does not transmit to the server 32, the smartphone 33, or the like when there is no person as a result of image analysis. By communicating when there is an abnormality or the like in this way, the number of communications can be reduced and the amount of communication data can be reduced. That is, the captured image may be sent to the server and the image analysis may be performed on the server side, but it may be determined on the edge side such as the drive recorder 10 as in the present embodiment, and communication may be performed only when there is an abnormality. If there is no abnormality, the image is not transmitted, so the amount of communication data can be reduced. Further, by processing on the edge side, if the image is not included as the predetermined information to be transmitted in the event of an abnormality, the amount of data can be further reduced.

Further, the predetermined information to be transmitted may be the same or different each time. For example, at the time of the first notification after switching to the monitoring mode, it is preferable to notify that a person exists, do not send other information such as an image, and send an image or the like after a predetermined number of times or a predetermined time has elapsed. .. Since the first notification is often present in or near the vehicle, the notification allows the driver to visually confirm the presence of the child. Further, even after a predetermined number of times or a predetermined time has elapsed, information having a large amount of data such as an image may be sent once every several times, for example. By doing this, the communication load can be suppressed, the presence of the child can be notified efficiently and quickly, and the actual situation can be notified with images from time to time to make it more realistic and return to the vehicle early. It is good because it can encourage.

As a result of image analysis, if there is no person, it is better not to perform further analysis. If the person does not exist, the child has not been misplaced or the child has been taken out, so even if the image analysis is performed thereafter, the analysis result of "does not exist" is continuously obtained. Therefore, the load on the drive recorder 10 may be reduced by not performing the analysis process itself. Further, even if the analysis result of "non-existence" is obtained once, there is a risk of erroneous determination. Therefore, for example, when the analysis result of "non-existence" is obtained a plurality of times, it is preferable not to perform the subsequent analysis.

Further, in the above-described embodiment, the presence or absence of a person is determined by image analysis, and if there is a person, the person is notified. It is good to do it. The second information may be, for example, the detection result of the temperature / humidity sensor 23. For example, when the mode is switched to the monitoring mode, if a person is detected, the image is transmitted based only on the image analysis, and after a predetermined number of times or a predetermined time has elapsed, the second information is detected when the person is detected. If the temperature or humidity exceeds the set threshold value, or if the temperature / humidity changes significantly, it should be sent, and if the temperature etc. is within the specified range even if a person is detected, it should not be sent. .. If you consciously leave your child in the car, it will be annoying if you receive an alarm continuously, and you may become an alarm. On the other hand, in this embodiment, the driver or the like is not transmitted when the temperature inside the vehicle is not likely to cause heat stroke, but is transmitted when the temperature is likely to rise or the like. It is good because it informs the emergency situation and gives an opportunity to return to the vehicle immediately.

In addition, for example, when there is a person in the car, the temperature inside the car is monitored, and when the temperature inside the car becomes higher or lower than a certain level, predetermined information is transmitted to the driver or the like. It is advisable to change to the notification function or to automatically start the air conditioner in addition to the function. By doing so, the temperature inside the vehicle becomes an appropriate range before the driver returns to the vehicle, so that the safety of the person remaining in the vehicle can be maintained. Such a function is also useful as an insurance product utilizing a connected car, for example.

In addition, image analysis should be able to recognize not only the presence or absence of a person but also the state of a person. It is good to be able to recognize the state of a person, for example, sleeping / waking / crying. Then, the recognition result may be transmitted.

Further, in the above-described embodiment, it is detected that the ACC is turned off based on the signal from the power supply device 30, but the present invention is not limited to this, and the ACC is turned off. For example, it may be acquired directly from the vehicle, or it may be detected by various methods.

On the other hand, when the vehicle is parked and stopped without turning off the engine, the ACC is not turned off. Therefore, for example, it is preferable to provide a means for detecting the driver's disembarkation and perform the above-mentioned processing when the driver's disembarkation is detected. As a means for detecting the driver's disembarkation, for example, a seating sensor installed in the driver's seat may be used. The seating sensor turns on when a person sits in the driver's seat and turns off when the person stands up from the driver's seat. Then, when the seating sensor installed in the driver's seat is turned from ON to OFF, it may be determined that the driver gets off. In addition, it is advisable to provide a sensor that detects the opening and closing of the door on the driver's side, or to acquire information on the opening and closing of the door from the vehicle. .. Further, it is advisable to use various methods such as setting the image pickup range of the camera so that the driver's seat is included and determining whether or not there is a person in the driver's seat by image analysis.

* Sound-based detection The control unit 16 acquires, for example, the voice detected by the microphone 12 when the mode is switched to the monitoring mode, and analyzes the voice. Voice analysis may be performed by a method using deep learning (neural network) or other machine learning. When the control unit 16 detects an abnormal sound by voice analysis, the control unit 16 transmits predetermined information to the registered destination using the communication unit 24. The predetermined information may be the analysis result, and in addition to the analysis result, position information, room temperature, humidity and the like may be sent. The abnormal sound includes, for example, the sound of glass breaking, a collision sound, a scream, a cry, and the like. The screams include, for example, a child's cry such as "help". The cry is, for example, the cry of an infant. The analysis result to be transmitted may be the presence or absence of abnormal noise, but the analyzed content may also be transmitted.

For example, when a sleeping child is left in the vehicle when getting off, the driver can know that the child has awakened by screaming or crying, which is an opportunity to return to the vehicle at an early stage. In addition, by knowing the abnormalities that have occurred in the vehicle due to the sound of glass breaking or collision, it is possible to go to see the state of the vehicle, especially when a child is left in the vehicle, it is necessary to return more quickly. It is good because you can know.

In the voice analysis, what kind of sound may be determined by various analyzes using a database or the like. Further, the voice analysis is not limited to the sound generated in the vehicle, but may be performed based on the surrounding sound outside the vehicle. For example, when a person who finds a child left behind in the vehicle is making noise outside the vehicle, the control unit 16 recognizes the child's misplacement or the state of the child inside from the recognized voice content. And send it.

Further, the operation timing in the detection based on the sound, the information to be transmitted, and the like can be the same as those in the embodiment and the modification in the detection based on the image described above. For example, it is advisable to add temperature and humidity to the information to be transmitted in the same manner as the analysis result, or to add an indoor image taken by a camera or the like. Further, it is preferable to provide a means for detecting the driver's disembarkation and to start the operation after the disembarkation is detected, and various elements can be applied.

* Detection based on the microwave sensor When the control unit 16 switches to the monitoring mode, for example, it acquires the output of the microwave sensor 22 and determines the presence or absence of an object moving in the vehicle. If there is a moving object, there is a possibility that a child or the like may be present in the rear seat 3 or the child seat 4, so the communication unit 24 is used to transmit predetermined information to the registered destination. Further, the detection based on the microwave sensor 22 may be performed periodically even after being transmitted once, and the determination result or the like may be output as in each of the above-described examples.

Further, the moving object based on the microwave sensor 22 is not limited to a human being, for example, and it is preferable that an animal in the vehicle can be detected. In this way, it is possible to detect misplaced pets.

In each of the above-described embodiments and modifications, the drive recorder 10 is used to transmit the predetermined information to the registered destination when an abnormality is detected, but the information is not always transmitted to the outside and the monitoring mode is set. In a situation where the driver is present in or near the vehicle, such as immediately after switching, the alarm may be issued from the speaker 19 of the drive recorder 10, for example.

Further, in each of the above-described embodiments and modifications, the electric power is supplied from the power supply device 30, but the electric power is directly supplied from the battery of the vehicle so that the electric power can be supplied even after the ACC is turned off. Or it may be provided with an internal battery so that power is supplied from the internal battery after the ACC is turned off. In such cases, the internal battery may be a rechargeable secondary battery.

Further, in each of the above-described embodiments and modifications, the implementation is performed as a part of the function of the drive recorder, but the present invention is not limited to the drive recorder, and may be implemented as a part of the functions of various in-vehicle devices, electronic devices, and the like. It may be realized as an independent device / equipment.

For example, in the case of a system using image analysis, for example, it is preferable to use a camera that supports LTE communication and is capable of edge AI processing. This camera is an AI camera that integrates a communication module, SIM card, camera, and power supply, and is capable of edge processing. In addition, device management such as replacement of AI algorithms and monitoring of communication connection status can be performed remotely via a cellular line. For example, NNC (Neural Network Console) may be used for deep learning and implementation of human detection by image analysis relatively easily. With this AI-processable camera, for example, the rear seat side including the child seat is photographed, and the obtained image is AI-processed to analyze the presence or absence of a person. Then, for example, when a person is detected in an image, the communication module may be operated to transmit the detection result or the like to a predetermined destination.

[Alarm based on the seating sensor installed in the child seat]
FIG. 3 shows a block diagram of a system of another embodiment. The system of this embodiment is another embodiment for preventing an infant or the like from being misplaced in a vehicle, and includes a main body device 40, a seating sensor 41, and the like as shown in the figure. In the present embodiment, it is configured as a dedicated device, but it may be implemented as a function of a drive recorder or other in-vehicle device, or it may be realized as an independent device / device. Further, the main body device 40 may be composed of the same housing or a plurality of housings.

In this embodiment, for example, the seating sensor 41 is installed in the child seat. It is preferable to provide a plurality of seating sensors 41 and arrange them at appropriate positions on the seat surface and the backrest portion of the child seat. The seating sensor 41 is turned on when an infant or the like is on the child seat, and turned off when the child seat is not on. The main body device 40 includes an interface unit 43 that receives an input signal from the seating sensor 41, a control unit 42, a speaker 45, an interface unit 46 that outputs a control signal to the vehicle side, and the like.

The interface unit 43 for the seating sensor 41 includes, for example, a pin jack or a connector for inserting the output terminal unit of the seating sensor 41, and transmits the output signal of the seating sensor 41 to the control unit 42. The control unit 42 has a function of outputting an alarm from the speaker 45 when the driver leaves the driver's seat or stands up when an infant or the like is on the child seat. Further, the control unit 42 has a function of outputting a signal for preventing the door lock from the vehicle side via the interface unit 46 when a predetermined condition is satisfied.

In order to realize such a function, the control unit 42 determines whether or not the seating sensor is ON, for example, as shown in FIG. 4 (S1). When the seating sensor is OFF, there are no infants or the like, so S1 is looped.

When an infant or the like is in a child seat, the control unit 42 determines whether or not the driver is away from the seat. Leaving a seat may be, for example, leaving the driver's seat or standing up from the driver's seat in the preparation stage. The determination of leaving the seat or the like may be based on, for example, providing a seating sensor in the driver's seat and turning off the output of the seating sensor or turning off the ACC. Based on this, it is possible that the person leaves the seat immediately after the situation is reached (the branch determination is Yes), but the branch determination may be Yes after a predetermined fixed time has elapsed. It is better to judge that the driver is leaving the vehicle immediately because the alarm sounds before the driver leaves the vehicle. Further, for example, when the driver has a slave unit capable of wireless communication with the master unit installed in the vehicle and the distance between the master unit and the slave unit is more than a certain distance, it may be determined that the driver is away from his / her seat. Further, for example, a camera for photographing the driver's seat may be provided, and the image captured by the camera may be analyzed to determine whether the driver is away from the seat or the like.

When the driver has not left his / her seat (No in S2), he / she returns to S1 and determines whether the seating sensor is ON / OFF. Then, when the driver's seat is away (Yes in S2), the control unit 42 issues an alarm from the speaker (S3). The alarm may be a buzzer sound or a voice alarm message. In this way, the driver notices that a child such as an infant is on the child seat by an alarm, so he forgets its existence and gets off the car, so that the child can be left behind in the car as much as possible. It can be suppressed.

Further, in the present embodiment, the control unit 42 prevents the vehicle door from being locked after the alarm is generated (S4). For example, the control unit 42 outputs a door unlock signal to the vehicle side via the interface unit 46. As a result, the door of the vehicle is kept unlocked without being locked, and even if a child is left in the vehicle, a third party (discoverer) can open the door of the vehicle and rescue the vehicle. It is also possible.

Then, when the seating sensor is turned off (Yes in S5), the control unit 42 releases the lockable state and makes it lockable (S6). As a result, the child or the like can be locked by lowering the child seat from the child seat, and the driver can lock the vehicle by performing a locking operation, for example, and can safely leave the vehicle.

In addition, by attaching a seating sensor to the child seat itself, it is possible to detect which seat the child seat is installed in. Furthermore, it is advisable to connect this system to a drive recorder and use the above unlocked state as an external trigger to notify the smartphone or server from the drive recorder. As in the above-described embodiment, the notification may be sent with predetermined information including a video.

As described above, by making the judgment of leaving the seat or the like on the condition that the ACC is turned off, it is possible to call attention when the engine is turned off with a child seat in the car and a child there. Further, by issuing an alarm by turning off the engine, for example, when the driver himself / herself performs the work of lowering the child from the child seat, it may be possible to suppress the generation of an unnecessary alarm by performing the work while the engine is running.

FIG. 5 shows another embodiment using a seating sensor. In this embodiment, for example, the function of determining whether to leave the seat or the like in the control unit 42 in the system shown in FIG. 3 is changed so that the driver can determine whether or not to leave the seat by using the opening and closing of the door on the driver's seat side. There is. Similar to the above, the control unit 42 determines whether or not the seating sensor is ON (S11). When the seating sensor is OFF, there are no infants or the like, so S1 is looped.

When the seating sensor is ON, the control unit 42 determines whether or not the door on the driver's seat side is in the open state (S12). If the door is closed, return to S11. When the door is opened, the control unit 42 waits for the next door to close (S13). Then, when the door is closed (Yes in S13), the control unit 42 issues an alarm from the speaker (S14). The alarm may be a buzzer sound or a voice alarm message. In this way, the driver notices that a child such as an infant is on the child seat by an alarm, so he forgets its existence and gets off the car, so that the child can be left behind in the car as much as possible. It can be suppressed.

Further, also in the present embodiment, after the alarm is generated, the control unit 42 prevents the door of the vehicle from being locked (S15). As a result, even if a child is left in the car, a third party (discoverer) can open the door of the car and rescue the child.

Then, when the seating sensor is turned off (Yes in S16), the control unit 42 releases the lockable state and makes it lockable (S17). As a result, the child can be locked by lowering the child or the like from the child seat, and the driver can safely leave the vehicle.

In the above-described embodiment, the alarm is issued after the door is closed after the door is opened, but the alarm may be issued when the door is opened without providing the processing step S13. However, in order for the driver to lower the child in the child seat by himself, the driver's door is often opened and moved outside the vehicle to the rear seat side, so the driver's door is used to lower the child. If you open the door, an alarm will sound, which may make the driver feel annoyed. Therefore, as in the present embodiment, the alarm condition is that the door is closed. For example, when the child is removed from the child seat with the door open and then the door on the driver's seat side is closed, the alarm is issued. It's okay because it doesn't ring.

In each of the embodiments shown in FIGS. 4 and 5, the lock is disabled in S4 and S15 so that the lock cannot be locked even if the lock is applied, but an alarm is issued when the lock is attempted. May be good. In this case, it is not necessary to give an alarm for S3 or S14, but if it is given, a double alarm may be given.

Further, instead of disabling the lock in S4 or S15, it is preferable to lock the lock after the alarm or to lock the lock when the lock operation is performed again after the alarm. By doing so, it is possible to prevent a suspicious person or the like from invading the vehicle by leaving the child or the like in the vehicle at the driver's will and locking the vehicle.

[Communication type temperature measuring device]
FIG. 6 shows an example of a system for preventing heat stroke of children and the like left in the vehicle based on the temperature inside the vehicle. The system 50 of the present embodiment includes a function of measuring the temperature inside the vehicle (for example, a temperature / humidity sensor 51), a communication function (for example, a communication unit 52), a control unit 53 that controls them, and the like. When the temperature inside the vehicle exceeds the set temperature, the control unit 53 notifies the registered destination using the communication function. For the communication function, for example, an LTE-M module capable of LTE communication may be used, and for example, the server 32 or the driver's smartphone 33 registered in advance is notified. When transmitting to the server 32, it is preferable to notify the driver's smartphone 33 or the like via the server.

When this system is installed in a vehicle and the temperature inside the vehicle approaches a temperature at which there is a risk of heat stroke after the engine is stopped, a notification is given to the driver's smartphone or the like to notify that the danger is approaching. By doing so, the driver receives the notification and takes appropriate measures toward the vehicle to prevent the high temperature inside the vehicle. Further, in the present embodiment, as in each of the above-described embodiments, the function of determining whether or not a child is present in the vehicle may be provided, but by not providing the function, the configuration may be simplified.

Further, the engine stop such as OFF may be detected, and then the room temperature may be monitored and notified when the condition is satisfied, but the engine stop detection function may not always be provided. In general, if the driver is on board and the engine is running, there is a possibility that the room temperature will rise to a dangerous room temperature that may cause heat stroke, for example, by using an air conditioner or opening windows. low. Therefore, it is often the case that the temperature inside the vehicle becomes higher than the set temperature during parking with the engine turned off. Therefore, by not providing the engine stop detection function, it is possible to install the engine independently of the vehicle, and it is sufficient to effectively take measures against heat stroke with a simple configuration.

In this embodiment, by notifying the smartphone when the temperature is high, it is possible not only to leave the child behind but also to leave the vehicle for a short time. In addition, by appropriately setting the temperature to be notified, it is possible to notify in advance from the caution stage, and it is possible to rush before the dangerous temperature is reached. The temperature to be notified may be set to an appropriate value as an initial value in consideration of the temperature at which there is a risk of heat stroke so that the user can change it by setting.

In heat stroke, temperature is one of the important factors, but humidity also has an effect. Therefore, it is advisable to provide a function for measuring temperature and humidity so as to notify when the relationship between temperature and humidity satisfies a predetermined condition. When humidity is taken into consideration, it is good to be able to notify even if the environment is such that heat stroke or the like may occur due to the humidity even if the temperature is relatively low.

[Communication type temperature measuring device + remote compatible operation]
In addition to the functions of the embodiment of the communication type temperature measuring device described above, it is preferable to have a function of connecting to an OBD, opening a window remotely, and enabling an engine start, for example. In this way, for example, when the driver's smartphone receives a notification of high temperature, a guide such as "Do you want to fully open the window?" Or "Do you want to start the engine?" Is displayed on the smartphone screen. When the "YES" button displayed on the screen is touched, remote operation becomes possible. As a result, the inside of the vehicle can be cooled by starting the engine by opening the window to take in the outside air or turning on the air conditioner in advance, and it is possible to prevent heat stroke of the child before rushing to the vehicle.

In this embodiment, it is an effective function in a situation where it is not possible to rush immediately even if a notification arrives. Moreover, even if the child can return to the vehicle immediately, the child can be released from the dangerous state as soon as possible by responding immediately.

In addition, such remote control may be performed only when it is dangerous. By doing so, it is possible to suppress the occurrence of situations such as unnecessary opening of windows to allow entry and exit, and erroneous starting due to the engine starting.

[In-car drive recorder (with motion detection)]
For example, the shooting area of the camera of the drive recorder shown in FIGS. 1 and 2 is set in the vehicle. Further, it has a function of registering, for example, the driver's smartphone 33 in the transmission destination of the communication unit 24, linking the drive recorder 10 with the smartphone, and transmitting the image being photographed by the drive recorder to the smartphone. As a result, the user can check the state of the child in the back seat in real time from the smartphone. In addition, for example, the state of a child can be seen even from a distance by LTE communication. Furthermore, it is advisable to use a drive recorder specialized for in-vehicle recording. Furthermore, if a temperature sensor is provided in the drive recorder so that the temperature inside the vehicle can be displayed at the same time, it may lead to early detection of heat stroke. It is even better to install a humidity sensor and display the humidity as well as the temperature. For example, in the example shown in FIG. 2, since the temperature / humidity sensor 23 is provided, both temperature and humidity can be displayed.

Further, the above-mentioned video confirmation includes, for example, a method in which the user voluntarily connects to the drive recorder for viewing, and a method in which the drive recorder transmits the video to the smartphone when there is movement in the vehicle by motion detection. Often, it is good to be able to select it in the user settings. Equipped with a motion detection function, it is also useful for crime prevention while parking.

[Smart Band]
FIG. 7 shows yet another embodiment of the system. The system of this embodiment includes a smart band 60. The smart band 60 includes, for example, a band portion 60a for being worn on a child's foot, leg, arm, or the like. The smart band 60 includes a biological information acquisition sensor 61 that measures biological information such as body temperature, heart rate, and blood pressure of the user wearing the smart band 60, a communication unit 62 that transmits the biological information to the smartphone 33, and a communication unit 62 thereof. A control unit 63 or the like that controls control is provided. Then, the smart band 60 is attached to, for example, a child's legs, legs, arms, or the like. As a result, for example, biological information such as the body temperature and heart rate of a child waiting in the vehicle can be constantly monitored using a smartphone 33 owned by a user away from the vehicle.

Further, the attachment portion of the smart band 60 may be, for example, a foot or a leg. For example, when worn on an arm, a child or the like sitting on a child seat may touch and remove the smart band 60, turn off the power, or cause a malfunction. On the other hand, when it is attached to the foot or leg, it is difficult to reach the smart band 60 in such a state of Suwa and others, and it is good that the above-mentioned problem can be suppressed as much as possible.

It is preferable that the smart band 60 has a function of sending a notification to the smartphone 33 when the child wearing the smart band 60 becomes in a dangerous state. A child is in a dangerous state, for example, when the detection value of the biological information acquisition sensor 61 exceeds a preset threshold value. In addition, this smart band may be configured to eliminate the screen and specialize in the transmission of information. Not providing a screen leads to cost reduction, simplification of configuration, miniaturization and thinning, and if a screen is provided, children may be interested in touching the screen, etc. It is good because it can suppress the inviting as much as possible.

Further, the notification destination of the smart band is a smartphone in the above-described embodiment, but the notification destination is not limited to this, and may be transferred to, for example, a smart watch carried by the user. You may not carry your smartphone with you at home, so it's a good idea to use a smartwatch that's easy to wear and check notifications.

Further, the present embodiment is not limited to the one worn on the child left in the vehicle, and can be used not only in the vehicle but also at home or on the go. For example, there are scenes where children are separated from their children not only in the double-income generation but also at home, which is good because it helps prevent unexpected accidents at each location.

In the above-described embodiment, the case where GPS is used as the satellite positioning system has been described, but GLONASS, Galileo, a quasi-zenith satellite system and the like may be used as long as the gist of the present invention is not deviated.
