Description

The present invention relates to a moving object position search system that receives a radio wave of a transmitter attached to or attached to a moving body and searches for the position of the moving body. In addition, the present invention relates to a moving object position search system capable of searching the position of a domestic cat or a stolen motorcycle.

問題 The problem of elderly people (including those with juvenile dementia) is a problem that involves the burden of the family in dementia and involves the local community, and is also an anxious and risky problem for the person who does hemorrhoids. It is important to create a mechanism that allows society to follow up when it happens that the road to return home is lost.
As a recent situation,
1. Increasing cases leading to missing people and accidents,
2. There is a limit to watching over family members and caregivers, and it is necessary to respond to the entire region.
3. Due to differences in regional characteristics, it is difficult to build scrums for residents in urban areas, and measures cannot be found.
4). Education for dementia has started for elementary school students to increase “watching eyes”
5. The idea to watch in everyday life is an effective mechanism regardless of the size of the city,
6). There is an urgent need to create a system that enables identity inquiry beyond the regional boundaries of administrative agencies.
That's it.

徘徊 Anti-devices have been put on the market to help householders and caregivers in measures for the elderly. The content of the function varies depending on the progress of aging. At present, the main countermeasures up to the first trap are those with name tags, etc.
1. Introduce equipment that sounds a buzzer when stepping on the front door. Or, when moving from home or facility, a device that detects by radio waves and communicates with specific low power radio is introduced.
2. Hold a terminal device with a GPS function, and in the event of an emergency, identify it by looking at the map from a PC or smartphone.
The family will take such a method (see, for example, Patent Document 1).

Patent Document 1: Japanese Patent No. 3731736

However, the above method has the following problems.
1. It is necessary to install facilities at all the entrances, and it is ineffective if the resident is not nearby. The image is bad because it seems to limit going out of the elderly. There is also a risk that can be perceived as physical restraint in providing care.
2. There are two types, including those used for theft tracking for theft tracking.
A. There is a GPS logger (recording) type, but only the position is recorded on the device. Therefore, the path can be specified only after the elderly person is found and the device is collected, so it is not useful for finding the elderly person who is missing.
B. Mobile phone networks and GPS-based devices are the strongest tools to search for, but mobile phone-type devices are the smallest but 7.9cm x 4.3cm x 2.25 There is cm, and it is not possible to take a portable method such as lowering it from the neck slightly larger than the palm size. As a result, there are many examples that can not be held when going out, and there are few users even if it is a rental product of the local government. The small box type is 3.7cm x 3.9cm x 1.5cm and can be loaded into shoes, but because it is small, the battery has only 5 hours. In addition, there is an example of going out without wearing shoes as aging progresses, and in the nursing care field, things of the current size are unpopular and can be worn. Also, all GPS type batteries have only a few days of battery, and can only be charged by touching a charger. However, the fact is that it is not practical in the nursing field because it is useless if it is omitted. Caregivers are also becoming more aware of their work “attention to people”, and “checking against equipment” is unreasonable due to busy work and lack of knowledge. In addition, the initial cost of purchase and the running cost of the network usage fee are incurred, and there is a problem that it is costly to make a contract for multiple units.

The Bluetooth standard (hereinafter referred to as “Bluetooth”) is known as a standard for inexpensive communication terminals in mobile communication. Bluetooth divides the 2.4 GHz band into 79 frequency channels, and performs frequency hopping that randomly changes the frequency to be used, and performs wireless communication at a maximum of 24 Mbps with Bluetooth-equipped devices with a radius of about 10 m to 100 m. However, in Bluetooth, the communication range with a radius of about 10 m to 100 m is the limit, and it cannot be used as a communication device for a system that detects elderly people.

The smartphone 3, the mobile communication device 4, or the fixed communication device 100 is collectively referred to as a beacon communication device in the present invention.

The transmitter 2 has a spherical shape with a diameter of about 3 cm and incorporates a battery. Therefore, it can be easily put in a talisman bag, incorporated into a part of a rosary, loaded into a walking stick, or sewn to the collar or inside of a garment or tag. As a transmission content, it has a function to transmit at least different IDs for each transmitter 2, and Bluetooth divides the 2.4GHz band into 79 frequency channels and performs frequency hopping to randomly change the frequency to be used, Wireless communication is performed with Bluetooth-equipped devices of about 10m to 100m. Then, a plurality of beacon communication devices (smartphone 3, mobile communication device 4, or fixed communication device) specify a specific ID to be searched for by the transmitter 2 attached to the mobile body or mobile person to be searched. When a radio wave having a specific ID is received, a message indicating that the radio wave is received is transmitted to the main control computer 6 and the program is downloaded in advance as an application through the Internet or the like. Yes.
Further, the transmitter 2 has a function of receiving Bluetooth radio waves (beacon radio waves) other than itself as an additional function, stores a specific ID of the received radio wave, and stores the specific ID of the received other person together with the specific ID of the other party. A specific ID also has a function of transmitting together with its own specific ID.

A search requester 9 such as a family member or a caregiver sends the search target ID of the transmitter 2 attached to or attached to the mobile object or the mobile person 1 to be searched from the terminal 8 or the like to the main control computer. Make a request. Alternatively, the search requester 9 may request the secretariat for a search request, and the operator of the secretariat may operate the main control computer 6.
The main control computer 6 also has a function of receiving the search target ID of the transmitter 2 attached to or attached to the mobile object or the person 1 to be searched, the search target IDs to the plurality of smartphones 3, and the mobile communication device. 4 or transmitted to the beacon communication device such as the fixed communication device 100 through the Internet or a communication line, the fact that the transmission of the specific ID from the beacon communication device has been received, and the received smartphone 3, mobile communication device 4, or Receiving position information of a beacon communication device such as the fixed communication device 100, the discovery of the transmitter 2 attached to or attached to the mobile object or person 1 to be searched and the position information are output to the display 7, Moreover, the program which outputs the effect of a discovery and a position to the distant terminal 8 via communication is provided. Also, if the search requester 9's consent is obtained, the face photograph registered in advance is registered in association with the specific ID, so that the face photograph is transmitted to the beacon communication device that has received the transmission of the specific ID. You can also verify your identity by sending it.
All the received beacon communication devices such as the smartphone 3, the mobile communication device 4, or the fixed communication device 100, regardless of whether or not the search request is specified by changing the setting. It is also possible to have a function of transmitting the ID of the main control computer 6 to the main control computer 6. At this time, all the IDs and position information received by the main control computer 6 are stored, and the information is stored when a search request is generated. It can also be used for searching.

In the embodiment of the present invention, the transmitter is
1) The form in the amulet case
2) The form of rosary,
3) The form charged in the walking stick,
4) Clothes collar or the inside of the collar or a form sewn on the tag,
5) Form completely waterproof with silicon resin or vinyl chloride,
It is comprised with at least 1 form.

In the beacon communication device of the smartphone 3, the mobile communication device 4, or the fixed communication device 100,
1. 1. Download application from application store Once installed, under the operation of this application,
The investigation is started: (The main control computer 6 activates the search / the investigation start by the operation of the secretariat operator)
That is,
1. 1. Receive search request with push notification Start application (may be always running)
3. 3. Automatically obtain search ID from main control computer 6 (may include server) Application termination. Or it works as it is.
5. The application receives Bluetooth radio waves (from transmitter 2). No response is made for radio waves that are not search IDs.
6). When the Bluetooth of the search ID is detected, it is displayed on the beacon communication device such as the smartphone 3. Operate the send button from the application (may be automatic send). Time / position information (position coordinates, etc.) is transmitted to the main control computer 6 (which may include a server).
8). The operator of the secretariat who desires can see the news information input by the holder of the smartphone 3.

Watching the above embodiment as a net (provisional name) project,
By simply launching an app from their own smartphone 3, a 100m radius search is possible, and a system that can be used to detect elderly people even in a wide area by placing it in the mesh. it can.

In the present embodiment, the following is further possible.
1. Use residents' smartphones as sensors for detecting elderly people,
2. Use the smartphone's short-range communication function (Bluetooth = commonly used to connect to cars, headphones, etc.)
3.最短 Use of the shortest, smallest and lightest electronic devices that the elderly wear
4). Practical application of maintenance-free operation technology, etc. that matches the current status of caregivers.

Compared with the existing contact network for protecting elderly people,
1. Contact of search request is overwhelmingly faster than FAX and telephone. 2. Since it is not necessary to convey the information of “searching for who (name)”, it is innovative to build a method that protects the privacy of individuals. It has the feature that it is innovative that the information of discovery reaches the end of the searcher instantly.

  In addition, in this system, when a search for an elderly person or the like needs to be performed, the transmitter 2 that has been mounted in advance is searched, but immediately after the search is started, the position of the transmitter 2 to be searched is determined. It is assumed that it cannot be specified (when no radio wave from the transmitter is received by any beacon communication device). Assuming such a case, all the reception records and position information of all transmitters 2 registered in advance are stored in the main control computer 6, and when a search request is received, the transmitter to be searched is stored. It is desirable to know the past position information of 2. Therefore, the main control computer 6 obtains the position information of the beacon communication device every time it receives a notification that the search target ID is received from the beacon communication device that has received the specific ID transmitted from the transmitter 2. The function of storing the location information of the transmitter 2 in time series is further provided, and the transmitter 2 that transmits the search target ID was not found when the search was required. Even in this case, it is desirable that the main control computer 6 has a function of outputting past time-series position information of the transmitter 2 to be searched.

The effects obtained from the present embodiment are as follows.
1. Since it is a mechanism that fully utilizes the current infrastructure of using residents' smartphones, it can be built at low cost.
2. There is no need to change the equipment to match the progress of aging, and it is possible to respond to emergencies simply by introducing a cheap and small transmitter as a protection in advance.
3. The whole society can raise the awareness of participants to protect the elderly in the community.
4). It is not always running and can only function in an emergency.
5. Since personal information is divided and operated, it is difficult to specify and management can be under the control of each individual.
6). Privacy is protected because personally identifying information such as name is not generally distributed.
Note that the location information of the transmitter 2 received by the beacon communication device is accumulated in the server, and the characteristics of each action can be determined by rearranging the information in time series.

[Transmitter 2]
1. Transmitters can be obtained at a low price.
Elderly people throw away transmitters, so it may be necessary to take multiple measures, such as putting one in a talisman, the other in footwear, and even on clothes. One elderly person can have multiple transmitters.
2. The transmitter is bluetooth and can be composed of a small 3cm x 3cm x 1.5cm sphere, 3cm in diameter, or even smaller. Can be.
3. Can be washed waterproof.
In addition, it has a thin design so that it does not interfere with daily life, and can be sewn into clothes.
To do.
4). The basic structure + transmitter chip + battery (or battery) can realize a light, thin, small, and low price, and the battery can be used for a long time by setting the transmission time to once every 4 seconds. As a short-range wireless communication technology, Bluetooth such as Class 1 is used.

[As receiver]
1. Use a commercially available smartphone.
The reception function is just by downloading a dedicated application to the smartphone and using the communication function of the smartphone from the beginning, so the overall system construction cost is low.
2. Residents can watch over and participate in the internet simply by downloading a dedicated app.
Even after an emergency such as missing, you can easily join the search by launching the app.
3. Residents can control the degree of participation.
You can ask the residents to express their intention to participate individually. There is no function to search for a specific transmitter (individual) on the smartphone itself.
Since the received information is automatically sent to the server ID, it is not necessary to know the name and characteristics of the elderly, and the privacy of the elderly and their families can be protected.

[Main control computer 6 (may include a server)]
1. Community function that gathers good intentions of local residents.
(Thanks messages from family members and caregivers can be viewed)
2.徘徊 Automatic verification function for elderly ID and search request ID (after verification, output to digital map)
3. Transmitter / resident registration function (alerts such as battery life cycle are also automatically transmitted)
As a point of system operation,
1. A movement for young people with a wide range of activities can be created.
2. It can handle access from various users (= various devices).

The feature of the present embodiment is that the transmitter 2 is overwhelmingly smaller and lighter than a device (cell phone) using GPS. Since the functions are narrowed down, it is inexpensive and does not cost much running costs. It is possible to avoid the “not brought out” state, which was the biggest problem with GPS devices, by being attached anywhere depending on the ingenuity of the householder. In addition, it is possible to build a program to connect elderly householders and local residents. Its main function is
1. ID registration from householders --------- Multiple transmitters can be registered 2. Acceptance of investigation requests from householders ---- Receptions can be made on smartphones, computers, and phones. Push notifications to smartphones in the area
---- Missing time for elderly homes x 6km radius
4). Function to inquire ID information automatically sent from residents' smartphone
---- Matching with investigation request ID A function to contact the family member of the ID that has been verified
---- Combination of E-mail / SMS / Voice call Acceptance of discovery reports from family members ------- Thank you for accepting messages. The point of the design is that the information linked to the ID does not need to be associated with the name only by the contact information of the householder, so privacy is protected.
Also, the actions necessary for residents to cooperate in the search are simple, just launch their smartphone app. There is no need to know the name, clothes, features, etc. of the elderly who are the subject of the search, and all search activities and communications for discovery are performed automatically.

The invention of the present application is an invention that supports nursing care sites. If this is named “Yui System”, anyone who has a smartphone can participate in this system as a volunteer. All you need to do is download an application called “.net”. The application automatically captures the weak radio waves transmitted by the elderly “talisans” and reports them automatically. The radio wave is really weak, reaching only about 100 meters, but it is as effective as actually searching by hand. It is difficult to find elderly people who have never met. Whether you are deceived? Although it is actually difficult to determine whether a search request has been issued, in the present invention, the determination is automatically performed by the application. Volunteers just have a smart phone and phone with an application, and if an elderly person comes within 100m, they can notify the discovery.

  The portable communication device 4 can be further applied to “car car navigation” as an application form. Detects weak radio waves (beacons) emitted by a person's transmitter using the car navigation communication function, accumulates time information in the car navigation system, and performs pairing with the owner's smartphone 3 when the owner gets into the car The information is transmitted to the smartphone 3, and the content of the transmitter 2 received by the smartphone 3 is sent from the smartphone 3 to the server 6. Bluetooth can only determine a short distance, but by mapping information of a plurality of smartphones 3 on a server, coordinates are derived and mapped on a map.

Furthermore, a mechanism for predicting behavioral patterns of dementia can be considered.
1. A mechanism that analyzes behavior patterns from the time of independence and predicts behavior patterns in the unconscious state.
Pre-registered mobile users can collect information such as personal walk courses from the start of dementia habits by recording location information at multiple points in time as they are obtained. Can be put. By referring to the past movement route and course in the event, effective information for searching and securing the position can be obtained.
2. A mechanism to collect information that cannot be detected at the time of search and determine the search direction.
From the number of smartphones and their location information, the location where the high-density search was performed is specified, and information is provided to the person who searches as an area that does not need to be searched in case of an accident.

Furthermore, when multiple requests such as a search request by a family member or a search request from a nursing facility or public institution are used in order to prevent the use of the search for elderly people from being used for other purposes (stalker purposes) In particular, it is important that only authorized persons (relatives, owners and mortgages in the case of objects) can start a search or display the search results. . On the other hand, it is also important to identify a person who does not want to be searched for the purpose of stalking and reject a search request or result report.
In Bluetooth, a specific ID is transmitted, but this alone cannot identify an individual, so personal information is protected. In addition, collation of personal information from a specific ID can be managed by narrowing down the client's authority management to the parties mentioned above, and the display of the results is controlled for the appropriate authority or person it can.

In addition, a mechanism is also considered in which distance information (possible with Bluetooth) in the radio waves received by multiple smartphones (two or more) is aggregated by the server, the direction and speed of the user's movement are calculated, and the current location is predicted. It is done. The content to be communicated does not include personal information. Personal information is not distributed. Nationwide local residents 5 holding smartphones 3 or mobile communication devices 4 who have agreed to cooperate in advance are classified according to the degree of cooperation and authority. It is conceivable as an application of the present invention that a mechanism for requesting the protection or securing of the user can be requested by telephone or e-mail.
