Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of a target person discovery support system 1.

The target person discovery support system 1 includes a beacon transmitting device 10 and a beacon receiving device 20 that are worn on a target person's shoes, an illumination type repeater 30 that is a lighting facility and has a wireless communication relay function, and registration related to the target person. When a guardian terminal 40 that transmits an information / search request and receives a subject's action history and other information, a volunteer terminal 41 that functions as a repeater, and information on the subject are accumulated and a predetermined condition is met And a cloud server 50 for outputting a predetermined instruction signal.

The guardian terminal 40 and the volunteer terminal 41 are both terminal devices but have different functions. The guardian terminal 40 is used when the guardian of the subject (including a family member, a caregiver, a doctor, a nurse, etc.) requests a search for the subject or confirms the situation (current location, etc.) of the subject. Used for. The volunteer terminal 41 is used when a person registered in the target person discovery support system 1 cooperates with a target person's search request, specifically when relaying a target person's beacon.

FIG. 2 is a diagram illustrating a functional configuration for explaining an outline of the target person discovery support system 1.
The beacon sending device 10, the beacon receiving device 20, the lighting type repeater 30, the guardian terminal 40, the volunteer terminal 41, and the cloud server 50 have functions as shown in FIG.

The beacon transmission device 10 transmits a beacon indicating individual identification information (user ID) for uniquely identifying the target person to the illumination repeater 30. The illumination type repeater 30 receives the beacon from the beacon transmission device 10 and transmits the user ID indicated by the beacon to the cloud server 50.

When the cloud server 50 receives search target person identification information as a search request from the guardian terminal 40, the cloud server 50 searches the user ID stored in the cloud server 50 for information on the search target person. When the cloud server 50 finds information about the search target person, the cloud server 50 transmits a search target person discovery notification to the guardian terminal 40. Furthermore, the cloud server 50 transmits an LED blink instruction signal (search target user ID) to the illumination repeater 30 in order to blink the LED of the beacon receiving device 20 attached to the search target person.

When receiving the LED transmission instruction signal transmitted from the cloud server 50, the lighting repeater 30 transmits a beacon indicated by the LED blinking instruction signal to the beacon receiving device 20. When receiving the LED blink instruction signal, the beacon receiving device 20 blinks the LED.

FIG. 3 is a block diagram showing the configuration of the beacon transmission device 10. The beacon transmission device 10 includes a beacon transmitter (for example, a Bluetooth (registered trademark) module) 11 that transmits a beacon that is an electromagnetic wave having a predetermined frequency, a battery 12 that supplies driving power to the beacon transmitter 11, and a Z-axis (vertical). And an acceleration sensor 13 for detecting the acceleration in the direction.

Further, the beacon transmission apparatus 10 includes an EEPROM (Electrically Erasable Programmable Read-Only Memory) 14 in which digital information of the user ID is stored, a RAM (Random Access Memory) 15 that stores a user ID read from the EEPROM 14, and a user ID. And a control circuit 16 for performing reading / writing and other control.

Before using the beacon transmission device 10, a seal is attached to the positive electrode or the negative electrode of the battery 12. When the user pulls out the seal, the power supply voltage of the battery 12 is supplied to each circuit in the beacon transmission device 10.
When the power supply voltage of the battery 12 is supplied for the first time, the control circuit 16 reads the user ID from the EEPROM 14, stores this user ID in the RAM 15, and erases the user ID in the EEPROM 14.

Thereby, as long as the energized state by the battery 12 continues, the RAM 15 stores the user ID, and the beacon transmitter 11 continues to transmit the user ID of the RAM 15. Thereafter, when the power supply voltage is lost due to the discharge or removal of the battery 12, the user ID stored in the RAM 15 is erased, and the transmission of the user ID is completely completed.
Here, even if the battery 12 is replaced with a new one, the EEPROM 14 and the RAM 15 do not store the user ID to be transmitted. For this reason, the beacon transmitter 11 detects a state in which the user ID is not set, and stops the beacon transmission process.

As described above, the beacon transmission device 10 can continue to transmit the user ID with the beacon as long as the energized state is maintained by the battery 12, and when the energized state is no longer maintained, the battery 12 is replaced. Even if it is done, the user ID cannot be transmitted. As a result, a third party cannot continue to use the beacon transmission device 10 while remodeling (battery replacement). That is, it becomes impossible for a third party to reuse the used beacon transmission device 10 without a regular purchase of the beacon transmission device 10 from the manufacturer (avoidance of use of the beacon transmission device 10 due to malicious intention). In addition, future exhaustion of user IDs can be prevented.

Further, the beacon transmitter 11 is driven only when the battery 12 is driven, and when the walking is detected by the acceleration sensor 13, the beacon transmitter 11 can operate for about 1000 hours or about six months to one year.
Specifically, the beacon transmitter 11 starts beacon transmission when the output value of the acceleration sensor 13 exceeds the threshold value during the stop of the beacon transmission process, and the beacon transmission period (for example, 30) from that point (start point). In a minute, the beacon is repeatedly transmitted and stopped periodically.

If the output value of the acceleration sensor 13 exceeds the threshold value during the beacon transmission period, the beacon transmitter 11 sets the time when the output value exceeds the threshold as a new start point of the beacon transmission period, and sets a new beacon transmission period. The beacon transmission / stop is repeated periodically.
If the output value of the acceleration sensor 13 does not exceed the threshold value within the beacon transmission period, the beacon transmitter 11 stops the beacon transmission process and stops its operation.

FIG. 4 is a block diagram showing a configuration of the beacon receiving device 20. The beacon receiving device 20 includes a beacon receiver (for example, a Bluetooth (registered trademark) module) 21 that receives a beacon that is an electromagnetic wave having a predetermined frequency transmitted from the illumination repeater 30, an LED 22 that emits light in an emergency, and the light emission of the LED 22 , A battery 24 that supplies power to the beacon receiver 21, the LED 22, and the control circuit 23, and an acceleration sensor 25 that detects acceleration in the Z-axis (vertical) direction. The following beacon transmission / reception uses Bluetooth (registered trademark), but is not limited thereto.

The beacon receiver 21 starts beacon reception when the output value of the acceleration sensor 13 exceeds the threshold value during the stop of the beacon reception process, and during the beacon reception period (for example, 30 minutes) from that point (start point). Perform reception processing.
When the output value of the acceleration sensor 13 exceeds the threshold value during the beacon reception period, the beacon receiver 21 sets the time when the output value exceeds the threshold value as a new start point of the beacon reception period, and sets a new beacon reception period. The beacon reception process is performed. If the output value of the acceleration sensor 13 does not exceed the threshold value within the beacon reception period, the beacon receiver 21 stops the beacon reception process and stops its operation.

The control circuit 23 does not cause the LED 22 to emit light during normal times (when it is not in an emergency state), and causes the LED 22 to emit light during an emergency. Specifically, the control circuit 23 compares the user ID indicated by the beacon received by the beacon receiver 21 with the user ID that identifies the target person to which the beacon receiving device 20 is attached, and When the user IDs match, it is determined that there is an emergency and the LED 22 is blinked.

The beacon transmitting device 10 and the beacon receiving device 20 are attached to shoes as follows. In the following, an example in which the beacon transmission device 10 is mounted on a shoe will be described, but the beacon receiving device 20 is also mounted on the shoe.

FIG. 20 is a block diagram showing a configuration of the illumination type repeater 30.
The illumination type repeater 30 is attached to various places in an urban area or a suburb as an illumination facility. However, the illumination type repeater 30 not only functions as a lighting facility but also functions as a repeater. For example, the illumination repeater 30 transmits the beacon information (user ID) transmitted from the beacon transmission device 10 to the cloud server 50 and transmits the user ID transmitted from the cloud server 50 to the beacon reception device 20 as a beacon. To do.

As shown in FIG. 20, the illumination type repeater 30 includes a beacon receiver 31 that receives a beacon from the beacon transmission device 10, a beacon transmitter 32 that transmits a beacon to the beacon reception device 20, and wireless communication. A wireless communication device 33 connectable to the Internet line; a power supply circuit 34 that converts an AC voltage supplied from the outside into a predetermined standard; and an illumination lamp 35 that is turned on based on the power supply voltage from the power supply circuit. Yes. The illumination lamp 35 may be an LED, a fluorescent lamp, or a light bulb.

The beacon receiver 31 supplies the received beacon user ID to the wireless communication device 33. The wireless communication device 33 transmits the user ID supplied from the beacon receiver 31 to the cloud server 50 via the Internet line using wireless communication such as WiFi (registered trademark) / PHS / 3G / 4G. . At this time, the wireless communication device 33 also transmits the relay ID, which is identification information of the illumination-type relay 30, to the cloud server 50 together with the user ID.

Further, when the user ID is transmitted from the cloud server 50, the wireless communication device 33 supplies the user ID to the beacon receiver 32. The beacon receiver 32 transmits the beacon of the user ID supplied from the wireless communication device 33 to the outside.

In addition, you may use not only the illumination type repeater 30 but the repeater of the structure remove | excluding the power supply circuit 34 and the illumination light 35 from the illumination type repeater 30. FIG. For example, you may use the repeater mounted in the emergency vehicle, the beacon repeater which operate | moves with portable terminals, such as a search volunteer, and the stationary (desktop type) beacon repeater installed in a station or a police box. For example, it can be incorporated into an electric table clock, a wireless router, or the like. As will be described in detail later, the volunteer terminal 41 functions as the above-described repeater. In addition, when the lighting type repeater 30 is installed in a store or a tourist information center, a Bluetooth (registered trademark) module is incorporated into the store information such as coupon information (discount information) and tourist information. Can be sent to other mobile terminals.

The guardian terminal 40 and the volunteer terminal 41 correspond to so-called smartphones. However, the guardian terminal 40 and the volunteer terminal 41 are not limited to smartphones as long as the functions described in this embodiment can be executed, and may be other hardware devices. For example, the guardian terminal 40 may be a so-called desktop PC (personal computer) or a mobile phone. The volunteer terminal 41 may be any device that can be configured such as a so-called tablet terminal or small PC.

In this embodiment, the guardian terminal 40 and the volunteer terminal 41 have the same hardware configuration as a smartphone, but different applications are installed to enable each function to be executed. The guardian terminal 40 may install an application for the volunteer terminal 41 in order to function as the volunteer terminal 41.

The guardian terminal 40 and the volunteer terminal 41 which are smartphones are a touch panel on which an operation input by the user is performed and an image or the like is displayed, a beacon transmitter / receiver (Bluetooth (registered trademark) module) for transmitting / receiving by beacon, Based on a communication device (3G / 4G line) for transmitting / receiving information to / from the cloud server 50, a GPS system for detecting the current position based on GPS information from a satellite, and a control program or installed application And a control circuit that performs overall control.

The touch panel displays various screens based on characters / images received by a beacon transmitter / receiver, a communication device, or an application. Moreover, a touch panel transmits the information of a user's operation input outside via a beacon transmitter / receiver and a communication device. The position information detected by the GPS system is transmitted to the cloud server 50. Thereby, the cloud server 50 can acquire and manage the current position of each volunteer terminal 41 when the current position of each volunteer terminal 41 is required.

The guardian terminal 40 transmits the user ID, name, age, gender, address, and contact information as registration information to the cloud server 50. The user ID is provided from the store when the user purchases the beacon transmitting device 10 and the beacon receiving device 20. For this reason, the user can input registration information immediately after purchasing the beacon transmitting device 10 and the beacon receiving device 20.

FIG. 21 is a block diagram showing the configuration of the cloud server 50. The cloud server 50 registers the target person information transmitted from the guardian terminal 40 and sequentially accumulates the target person position information to search for the requested target person information. In addition, the cloud server 50 transmits an LED blink instruction signal to the beacon receiving device 20 attached to the subject who has requested the search.

Specifically, the cloud server 50 includes a communication device 51 connected to the Internet line, a storage unit 52 that stores a database and other various information, and a CPU 53 that performs data read / write and other controls. ing.
When the communication device 51 receives the registration information of the subject person from the guardian terminal 40, the CPU 53 stores the registration information in the storage unit 52. Thereby, the subject database is constructed in the storage unit 52.

FIG. 22 is a diagram showing a subject database. The subject database includes a user ID, name, age, gender, address, and contact information. The user ID, name, age, gender, address, and contact information are information transmitted from the guardian terminal 40.
Moreover, CPU53 will memorize | store the received information in the memory | storage part 52, if the communication apparatus 51 receives the user ID and repeater ID of the subject who are outside. Thereby, a movement history database is constructed in the storage unit 52.

FIG. 23 is a diagram showing a movement history database. The movement history database has date and time, repeater ID, and user ID. FIG. 23 shows which target person (user ID) was in which place (where the repeater is installed).

24A shows a smartphone-type beacon receiving device, FIG. 24B shows a desktop-type beacon receiving device, and FIG. 24C shows an illumination-type beacon receiving device.
FIG. 25 is a diagram illustrating an installation location of the beacon receiving device. The illumination-type beacon receiver can be exchanged for fluorescent lamps in stores, bus stops, banks, and convenience stores, mainly in the terminal station. Desktop beacon receivers are installed in police boxes and station offices. These should be installed at regular intervals and radially from the station in consideration of traffic lines. In places where the illumination type beacon receiving device cannot cover the smartphone, a smartphone with a dedicated application installed serves as a substitute for the beacon receiving device.

FIG. 26 is a diagram schematically illustrating the current position of the target person and the installation location of the illumination repeater. FIG. 27 is a diagram illustrating a data accumulation state of the movement history database.
For example, when the illumination type repeater 30 with the repeater ID = A008 receives the beacon with the user ID = LDS 4321, the user ID = LDS 4321 and the repeater ID are sent to the cloud server 50 to notify the beacon detection. = A008 is transmitted. The cloud server 50 records, as the latest information (0022), information on the date and time when the information is received together with the user ID = LDS 4321 and the relay ID = A008 in the movement history database. Thus, the cloud server 50 constructs a movement history database by sequentially recording information transmitted from each illumination type repeater 30.

In addition, when there is a search request for a specific target person from the guardian terminal 40, the cloud server 50 performs the following processing.
FIG. 28 is a diagram illustrating a movement trajectory of a subject who has made a search request. FIG. 29 is a diagram showing the location of the subject who has made a search request. When there is a search request for a specific target person (for example, user ID = LDS4321), the cloud server 50 refers to the movement history database, and the cloud server 50 detects the beacon of the user ID = LDS4321 of the lighting type repeater 30 detected. The repeater ID is searched, and the searched repeater IDs are arranged in time series. As a result, the movement trajectory of the subject can be understood.

By the way, it is not possible to know where the subject was specifically from the repeater ID alone. Therefore, the storage unit 52 stores a relay ID-position correspondence table.
FIG. 30 is a diagram showing a relay ID-position correspondence table. The repeater ID-position correspondence table shows a correspondence relationship between a repeater ID for identifying the illumination type repeater 30 and position information (latitude and longitude) of the illumination type repeater 30. Thus, when the repeater ID is determined, the specific installation location (position information) of the illumination type repeater 30 indicated by the repeater ID is determined.

When the target person is missing, the guardian terminal 40 can transmit search request information requesting the search for the target person to the cloud server 50. After transmitting the search request information, the guardian terminal 40 receives information related to the target person from the cloud server 50 and, for example, the installation location (position information of the illumination type repeater 30 that detected the user ID of the target person) ) And the detection time are displayed in time series.

In the target person discovery support system 1 configured as described above, when the target person suddenly hesitates, the following processing is performed.
FIG. 31 is a flowchart showing a target person search support routine. When the target person search support application is launched, processing in step S1 and subsequent steps is performed.

In step S <b> 1, the user inputs the user name and password from the input screen of the guardian terminal 40.
FIG. 32 is a diagram illustrating an input screen of the guardian terminal 40. The guardian terminal 40 transmits the input information to the cloud server 50, and when successfully authenticated, the guardian terminal 40 can communicate with the cloud server 50.

In step S2, the guardian terminal 40 displays a map screen.
FIG. 33 is a diagram showing a map screen after authentication. Here, it becomes possible to input the user ID (possible nickname) of the search subject. When the user ID is input, the process proceeds to step S3.

In step S <b> 3, the guardian terminal 40 transmits the input user ID to the cloud server 50. At this time, the cloud server 50 starts searching for information related to the user ID.

Specifically, the CPU 53 of the cloud server 50 searches for the repeater ID associated with the user ID from the action history database of the storage unit 52, and sets the latest “date and time” from the searched repeater IDs. The associated repeater ID is selected. Then, the CUP 53 reads the position information corresponding to the selected repeater ID with reference to the repeater ID-position correspondence table. The CPU 53 transmits the read position information to the guardian terminal 40 as the position information of the search target person.

As a result, the position of the search target person (the point where the latest beacon of the search target person has been received) is displayed on the map on the guardian terminal 40. Further, when “search start” is clicked, the process proceeds to step S4.

In step S4, the guardian terminal 40 transmits to the cloud server 50 an instruction signal for blinking the user ID of the search target person and the LED 23 of the search target person.
When the CPU 53 of the cloud server 50 receives the above signal via the communication device 51, the CPU 53 transmits the user ID specified by the guardian terminal 40 to each lighting repeater 30.

In each lighting repeater 30, the wireless communication device 33 receives the user ID from the cloud server 50. The beacon transmitter 32 transmits a beacon indicating the user ID received by the wireless communication device 33.

In the beacon receiving device 20, the beacon receiver 21 receives the user ID of the beacon transmitted from the illumination type repeater 30.
The control circuit 22 compares the user ID of the beacon received by the beacon receiver 21 with a preset user ID (user ID for identifying the user wearing the beacon receiving device 20). If the two user IDs match, the LED 23 blinks. As a result, the search target person can be easily found from those around him and protected by a third party.

In step S5, the CPU 53 of the cloud server 50 reads the position information corresponding to each of the plurality of repeater IDs searched in step S3 with reference to the repeater ID-position correspondence table stored in the storage unit 52, These position information is transmitted to the guardian's terminal 40 together with the date / time information.

FIG. 34 is a diagram showing a map screen of the guardian terminal 40. As shown in the figure, on the map screen, the trajectory of the search target person is displayed on the map, and the passing point of the trajectory is displayed as text information. Thereafter, when the beacon transmitted from the search target is received at another place, the map screen is automatically updated.

In step S <b> 6, the CPU 53 of the cloud server 50 compares the trajectory of the search target person (the latest position information obtained in step 5) with the past trajectory of the search target person, and determines the walking speed of the target person. The distance that can be moved (predicted movement range) calculated from the above is predicted and transmitted to the guardian terminal 40. Here, the following processing is executed.

First, the CPU 53 matches or is closest to the last recorded (latest) position of the search target person from the past movement trajectories of the search target person in the movement history database stored in the storage unit 52. Search for position P _n . In addition, _P 1 the past movement locus of the search _{subject, P 2, ···, P n} , P n + 1, and .... CPU53, for all search positions _{P n} acquires the position _{P n + 1} is the next destination, and counts the number of occurrences of each of the positions _{P n + 1.} The CPU 53 selects the position P _{n + 1} with the highest number of appearances as the next predicted destination.

Further, the CPU 53 calculates the average walking speed v of the target person based on the past movement trajectory of the search target person in the movement history database. Specifically, the CPU 53 performs the following calculation.
v _n = (distance between P _n and P _{n + 1} ) / (elapsed time between P _n and P _{n + 1} )
v = (Σv _n ) / n
Incidentally, v _n is the case of 5 [km / h] or more values, search subject is assumed using moving means other than walk. At this time, in v = (Σv _n ) / n, v _n is excluded from (Σv _n ), and n decreases by the number of excluded v _n .

Finally, the CPU 53 sets the range that can be moved within one hour on foot (within a circle with a radius of v [km]) as the predicted movement range centered on the next predicted destination position _{Pn + 1.} . And CPU53 transmits the information which shows this estimated movement range to the guardian's terminal 40 which requested the search via the communication device 51. Thereby, the predicted movement range of the search target person is displayed on the map screen on the guardian terminal 40 that has requested the search.

FIG. 35 is a diagram illustrating the predicted movement range displayed on the map screen. As shown in the figure, the predicted movement range of the search target person is displayed in a circular area having a radius v [km] with the position P _{n + 1} as the center. A blue dotted line represents a destination predicted from the past movement trajectory of the search target person in the movement history database.

It should be noted that the information on the target person is not limited to the guardian terminal 40 but may be another device, for example, a desktop beacon receiving device. Desktop beacon receivers are installed in police boxes, station offices, and government offices, for example. When the guardian makes a search request or a detection request, the desktop beacon receiving device displays the data of the target person when the search target person approaches. Thereby, since the police officer, the station clerk, and the office clerk can recognize that the search target person is approaching, the search target person can be easily protected.

By the way, when the search target person moves to an area where the lighting repeater 30 is not permanently installed, the position of the search target person cannot be specified. Therefore, for example, a police vehicle, a fire-fighting vehicle, or the like may be mounted with a mobile repeater to expand the beacon reception area. In this case, the mobile repeater measures the position information by the GPS system at the timing when the beacon is received, and transmits the measured position information to the cloud server 50 together with the user ID of the received beacon. The mobile repeater uses a 3G / 4G line when transmitting to the cloud server 50.

Volunteer terminal 41 functions as the above-mentioned mobile repeater and can expand the beacon reception area of the present system 1. The volunteer terminal 41 is installed with a beacon relay application. The beacon relay application relays the target person's beacon when a guardian requests a search for the target person.
On the other hand, when there is a search request for the target person from the guardian terminal 40, the cloud server 50 transmits information about the search target person (number of persons, etc.) to all communicable volunteer terminals 41.

FIG. 36 is a diagram showing an icon of a beacon relay application. When there is a search request for the target person from the guardian, the number of current search requests is displayed on the touch panel icon of the volunteer terminal 41.

FIG. 37 is a diagram illustrating a search request status displayed immediately after the beacon relay application is activated. When the beacon relay application is activated, the volunteer terminal 41 requests the search server information from the cloud server 50. When the cloud server 50 receives a search requester's information request from the volunteer terminal 41, the cloud server 50 transmits information on how many search requests each municipality has to the volunteer terminal 41. As a result, the number of search requests in each municipality is displayed on the touch panel of the volunteer terminal 41. Then, when the letter “participate in search” is tapped, the volunteer terminal 41 starts operation as a repeater.

Specifically, the volunteer terminal 41 starts the beacon reception process when the letter “participate in search” is tapped. When the volunteer terminal 41 receives and detects a beacon from an arbitrary beacon transmission device 10, the volunteer terminal 41 displays a discovery notification screen.

FIG. 38 is a diagram illustrating a discovery notification screen when the volunteer terminal 41 detects the beacon of the target person. At this time, the volunteer terminal 41 notifies the user that the beacon of the target person has been received with characters and sounds. Further, the volunteer terminal 41 measures the current position information by the GPS system, and transmits this position information and the received beacon user ID to the cloud server 50.

On the other hand, when the cloud server 50 receives the user ID and the position information transmitted from each volunteer terminal 41 functioning as a repeater, the cloud server 50 sends the search request for the user ID (person to be searched) to the guardian terminal 40. The received user ID and its position information are transmitted. Thereby, the position of the search target person is displayed on the guardian terminal 40, and the guardian can confirm the current position of the search target person.

In FIG. 38, when the character “OK” on the display screen is tapped, the next discovery history screen is displayed.
FIG. 39 is a diagram showing a discovery history screen. The date and time when the beacon of the target person was received is displayed on the discovery history screen. When the date and time are tapped, the discovery location screen is displayed.
FIG. 40 is a diagram showing a discovery place screen. On the discovery location screen, the pinpoint that received the beacon of the subject and a map around it are displayed.

As described above, the target person discovery support system 1 uses the beacon transmission device 10 and the beacon reception device 20 driven by the battery without using the GPS system. Thereby, continuous use for six months or more is possible without battery replacement, and it can prevent that subjects, such as a dementia patient and a child, are missing.

In addition, when the lighting repeater 30 receives the beacon of the target person, the target discovery support system 1 immediately transmits the information to the guardian's terminal 40 such as the guardian, so that the location of the target person is almost real time. Can be contacted by parents.

Further, when the guardian makes a search request for the target person, the target person discovery support system 1 blinks the LED 23 of the beacon receiving device 20 attached to the target person to indicate the presence of the search target person in the surrounding area. Can be informed.

In addition, in the area where the illumination type repeater 30 is not installed, the target person discovery support system 1 activates and operates the beacon relay application of the volunteer terminal 41, so that the searchable area of the target person can be set for each volunteer. It can be expanded to the peripheral area of the terminal 41.

In addition, this invention is not limited to embodiment mentioned above, It can apply also to what was changed in the design within the range of the matter described in the claim.
In the above embodiment, the cloud server 50 transmits the information about the search target person to all communicable volunteer terminals 41 when there is a search request of the target person. Good.

For example, after obtaining the predicted movement range as described above, the cloud server 50 confirms the position information of each volunteer terminal 41 and transmits search request information to the volunteer terminals 41 within the predicted movement range. May be. At this time, the search request status within the predicted movement range is displayed on the volunteer terminal 41. Then, the volunteer terminal 41 may start the beacon reception process in the same manner as the above-described embodiment when the letter “participate in search” is tapped. Thereby, since the target person discovery support system 1 can request a direct search only to a user near the search target person, it is possible to discover the search target person at an early stage and confirm accurate position information. it can.

The beacon transmission device 10 is not limited to being worn on shoes, but can be worn on hats, clothes, bags, canes, and necklaces. The nonvolatile memory is not limited to the EEPROM 14 and may be any non-volatile memory that can hold information even when power is not supplied, such as a mask ROM, PROM, EPROM, EEPROM, FeRAM, flash memory, or the like. Further, the RAM 15 may be a DRAM or an SRAM as long as it is a volatile memory.

Furthermore, in addition to the configuration shown in FIG. 3, the beacon transmission device 10 may include a push button for transmitting a panic signal for preventing the kidnapping of the subject and an EEPROM 14 in which the panic signal is stored. The beacon transmission device 10 may include a switch that turns on when the string is pulled out, instead of the push button.

In such a beacon transmission device 10, when detecting a long press of the push button, the control circuit 16 reads the user ID and panic signal from the EEPROM 14 and stores the read user ID and panic signal in the RAM 15.

By the way, in a normal case (when a long press of the push button is not detected), the beacon transmitter 11 reads the user ID from the RAM 15 and outputs the user ID to the outside with an output of, for example, about 80% of the maximum output. Always send to.

On the other hand, when a long press of the push button is detected, the beacon transmitter 11 outputs the user ID and panic signal stored in the RAM 15 at the maximum output and at an arbitrary time interval (for example, every minute). Send it out. That is, when the push button is pressed for a long time, the beacon transmitter 11 further transmits a panic signal in addition to the user ID.

Then, when the cloud server 50 receives the panic signal transmitted from the beacon transmission device 10 via the illumination type repeater 30, the emergency information regarding the target person (the person wearing the beacon transmission device 10 that transmitted the panic signal). And the position information is transmitted to the guardian terminal 40. Thereby, the guardian can confirm an emergency state and its position.

In the above-described embodiment, the beacon transmission device 10 assumes a coin-sized size and shape type with a button-type battery as shown in FIGS. Type (hereinafter referred to as a cover case type).

The cover case type beacon transmitter 10 is equipped with a rechargeable battery and can be used for a much longer period (one year or more) than a button type battery. Further, since the cover case type beacon transmission device 10 can be carried together with a so-called smartphone, it is possible to record its own location information on the server even without a repeater. For example, it can be effectively used as a tool for keeping a record of the amount of exercise such as running and a record of a travel destination.

The beacon transmission device 10 can also transmit a user ID in the form of a bucket relay by multi-hop routing if the wireless communication standard “Wi-SUN” (registered trademark) using sub-gigahertz is used. is there. Multihop routing is a wireless network that enables not only direct communication between terminals but also communication with a wider range of terminals through other terminals. As a result, the problem of “the user ID may not reach” can be avoided even in a place where there is no wireless environment.

Furthermore, the target person discovery support system 1 is applicable not only to humans but also to pet discovery support. In this case, the beacon transmission device 10 may be attached to a pet collar.

Also, the subject discovery support system 1 can issue an alert for prevention of heat stroke or influenza. In this case, the beacon transmission device 10 includes, for example, a temperature / humidity sensor (not shown) in addition to the configuration shown in FIG. When the beacon transmission device 10 reaches a certain temperature and humidity, for example, the beacon transmission device 10 transmits alert information for calling attention of influenza to the cloud server 50. The cloud server 50 transmits alert information to the guardian terminal 40. When the guardian terminal 40 receives the alert information from the cloud server 50, the guardian terminal 40 displays an alert screen for calling attention of influenza as shown in FIG.

As described above, when the target person carrying the beacon transmission device 10 is in the room, the target discovery system 1 alerts the guardian terminal 40 of the risk of becoming influenza (or heat stroke). When the target person goes out, the target discovery system 1 records the position information of the target person. Furthermore, when the subject is deceived, the target discovery system 1 predicts the tip of the subject and detects that the subject has fallen by the acceleration sensor, and then sends the alert information to the guardian terminal 40 via the cloud server 50. You can leave.
