Description

[0001] The present invention relates to a monitoring system for a disabled person and an elderly person,

The present invention aims at providing a service for the handicapped and the elderly by using the short-distance wireless communication method of Bluetooth, and basically the Bluetooth communication is technically based.

Bluetooth uses 2.4GHz ISM bands worldwide for unlicensed use. In the ISM band, a spectrum spreading method is basically used. However, a frequency hopping (FH) scheme is adopted in which the circuit configuration can be simplified and interference is relatively strong in a microwave oven.

All Bluetooth devices are all the same in terms of hardware, but depending on the situation, they take a state called master or slave. They constitute the minimum configuration unit PICONET. In addition, a standby state in which the reduction in power consumption is conscious is also defined.

The Bluetooth device that has first started the communication becomes the master, and synchronizes the hopping pattern pattern with the slave in the PICONET. The communication in the PICONET is managed by the master. Basically, transmission and reception are performed in TDD (Time Division Duplex) in units of one hopping slot (625 μs = 1/1600 sec). The throughput of data transmission is up to 721kbps in a single direction / asymmetry.

Bluetooth supports not only asynchronous data but also isochronous data, that is, voice data. The speech CODEC employs 64 kbps CSVD and logPCM. The protocol stack of TCP / IP is implemented in the upper part of L2CAP. The present invention uses Bluetooth wireless local area communication, location recognition technology and various sensors based on the above technology to transmit location and status information to a guardian when an elderly or disabled person is in an emergency, The present invention aims at creating a system capable of taking a plurality of images.

Bluetooth is an industry standard for PANs (Personal Area Networks), which uses the IEEE 802.15.1 standard. Bluetooth allows multiple devices to communicate with each other using radio frequencies that are available globally at a safe and low cost.

In general, Bluetooth wireless systems use the Industrial Scientific and Medical (ISM) frequency band of 2400 to 2483.5 MHz. In order to prevent the interference of other systems using the upper and lower frequencies, a total of 79 channels, 240 MHz to 2480 MHz except 24 MHz to 2 MHz and 2483.5 MHz to 3.5 MHz, are used. The Bluetooth uses frequency hopping Frequency hopping is a technique that moves a large number of channels quickly according to a specific pattern and transmits data in small increments. Bluetooth hopes 1600 times per second to the assigned 79 channels, so that many Bluetooth devices have a unique frequency If you set the Bluetooth mode, the device will emit its own frequency and will not collide with other devices. Bluetooth can penetrate only one concrete wall. It has wireless strength and is not only a wireless earphone, wireless headset, wireless speaker, Widely it has been used in the line Mouse, Wireless keyboard.

Nowadays, the performance of the Bluetooth device is improved, so you can monitor a distance of about 3 inches (5 cm) to 150 bits (about 45 cm). Compared to NFC (near field communication), it has a wider range of beacons that can detect position more precisely than GPS (satellite navigation system), and it has a wireless sensor that recognizes the near location. Beacon is installed as a smartphone with Bluetooth 4.0 technology In this approach, beacons and smart phones can provide information and services through mutual recognition.

The present invention combines basic Bluetooth wireless local area communication technology, beacon location recognition technology, and various sensors to transmit the location and status information to a guardian in real time when an elderly or disabled person is in an emergency, It is the essence of the present invention to describe the logic, the process and the detailed method of building an information system that provides probation services for people with disabilities and the elderly as an invention aimed at creating an information system capable of taking rescue calls.

An object of the present invention is to provide an information system capable of delivering state information of a disabled person and an elderly person to a guardian in real time and capable of quick relief measures in case of an emergency. The elderly and the disabled need a sense and communication tool that can check the status information at a short distance. This means that they use a smartphone with high penetration rate, use Bluetooth for wireless communication and use a beacon for local location recognition. An elderly person living alone or a person with a disability living alone can make an information system that urgently responds to emergencies. In order to realize such a system, wireless communication, location and state accuracy should be basically performed. In order to realize this, it is necessary to reprocess the frame at the signal frequency generation stage of the beacon to increase the accuracy and performance of the position, It is necessary to analyze and reprocess the information of the beacon signal and to provide service by making it as a user and manager application.A component constitutes an access point for each person with a disability and the elderly, The information should be provided to the guardian, and the information should be provided to the probation officer or the hospital staff through the probation system server. In addition, the Manager Tools should be developed to manage the disabled and the elderly at a time.

It is the present invention to develop logic, processes and implementation details methods for configuring a probation system for persons with disabilities and the elderly using this overall Bluetooth communication method.

The present invention is not only a model for creating a user service using Bluetooth's location sense or information communication, but also a logic and a construction method that can implement various kinds of senses to a disabled person or an elderly person to implement a disabled person and an elder care observation system. In the present invention, various sensors such as beacon position recognition technology, Bluetooth local communication technology, frame reprocessing for the signal frequency, various sensors, gyroscope, geo-megnetic, accelerometer and G- It is characterized by the fact that the guardian or probation officer obtains the information and grasps the status and location information in real time and responds promptly in the event of an emergency, thereby creating a safe probation system for the disabled and the elderly. In the case of the position sensor described in the present invention, it is possible to develop a specialized service capable of exchanging positions and information between the inside of the apartment building and the inside of the cellar, the attic room, and the home, which can not be covered by the GPS area, and the Gyroscope, Geo-megnetic, Accelerometer, G-sensor, etc., health status or danger situation of the handicapped person and the elderly person can be provided to the guardian or the probation supervisor as the perception and data. As described above, according to the present invention, Location recognition technology, and smartphone sensors to create real-time probing systems for people with disabilities and the elderly.

The present invention relates to a method for creating an information system capable of taking emergency relief measures by transmitting position and status information to a guardian in real time when an elderly person or a disabled person is in an emergency in the room Content.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a diagram of the working principle of a probing system.

101Access Point1 and Access Point2, and 102Access Point3 and Access Point4 refer to the location-aware Bluetooth installed at the home of the handicapped and the elderly, which serves as a probation server to transmit the location of a disabled person or an elderly person at home, When an emergency occurs, the nearest probation officer's smartphone informs the emergency situation and informs the location.

103 probing server computes the distance and coordinate information of the current access point and the location of the smartphone of the handicapped and the elderly through the converter, which is the locating agency information (LAI) received from the access point. It is stored in the database in real time.

In addition, the SmartPhones owned by the probation observer check whether the probation observer is abnormal through the built-in gyroscope sensor, and store the change value A in the database by time.

The next step is to check the abnormality of the probation observer through the Geo-magnetic sensor and store the change value B in the database by time. Then, the next step is to check the abnormality of the probation target through the accelerometer sensor, and store the change value C in the database by time. Next, the next step is to check the abnormality of the probation observer through the G-sensor, and store the change value D in the database by time. Next, the Smarphone Health Check value change value E in a normal state And stores it in the database. When the value of the stored change in the time of the probation target is calculated as A + B + C + D + E = E, the emergency code is stored in the probation server, Point and the nearest person to the probation observer and the elderly report observer.

As shown in Fig. 2, the 201 elderly or disabled access point reprocesses the frame and sends a parameter called LAI to the probation server. Then, the probation server saves the near location through the nearby AP and stores it in the designated database in case of escaping to the inside or outside of the probation observer based on the LAI value, and transmits it when the emergency code occurs.

The information received from the Access Point, such as 204, includes the MAC address, the ID of the AP, the location information of the AP, and the LAI. The LAI is received in the form of 03_10011102120413051406150716081709, which indicates the indoor movement path and the change value do. Based on this, A + B + C + D + E is calculated by sequentially comparing the change values of 205 Gyroscope: A, 206Geo-magnetic: B, 207Accelerometer: C, = E, and if there is an error, insert the Emergency Code into the LAI. The LAI with the Emergency Code inserts the ID of the AP that received the Emergency Code and the ID of the probation officer into one pair. Then, it extracts the Smartphone ID closest to the Access Point of the disabled and the elderly and transmits it to the probation supervisor so that the nearest person in the crisis situation can manage the disabled and the elderly.

Figure 3 shows the flow chart of the probation system. The designated Access Point of 301 verifies ID, Mac Address and LAI value, Locating Agency Infomation at 305 Pair A. If it is Yes, Smart ID, Smartphone MAC Address, Smart The LAI value of the phone is verified at 309 Pair B. Then, the gyroscope, the geo-magnetic, the accelerometer and the G-sensor of the smartphone of the specific smartphone, that is, the probation target, are turned on And the time variant value is transmitted to the probation server. The transmitted change value and the normal health check value registered at the time of user registration are performed, and when the abnormality occurs, the emergency code is generated and it forms the AP and the pair of the probation observer through LAI. That is, the AP ID is verified at 320, the smartphone ID is verified at 330, and the AP and smartphone pair is verified at 340. The smartphone that has been verified confirms that the sensors are turned on and the change in the time is transmitted to the probation server. When the change value of the sum of the change values is compared with the existing health check value, an emergency code is generated. The nearest probation officer will send AP ID, smartphone ID and Health Check information to the nearest probation officer to help the handicapped or elderly people who are in an emergency at home. In addition, according to the setting, it is possible to manage the occurrence status of real-time emergency situation to the disabled person or the elderly to be observed by linking with a system of a hospital, an emergency evacuation agency, a business or a welfare organization together with a smartphone of a probation officer.

Figure 4 shows the specific form of the surveillance system described above. The disabled person is present in the room and the elderly person is outdoors. 401 The probation officer is 3 km away from them. 402 The probation officer is 4 km. 403 The probation officer Is 1km away, and the 404 probation officer is 2km away. In the current state, the probation server receives the emergency code signal and location information about the health abnormality of the handicapped person or the elderly person through the access point installed at home or outdoors,

403 Transmit the status of persons with disabilities and the elderly, who are probation observers of the probation officer's smartphone, and inform them of the emergency situation. If the 403 probation officer does not receive a signal from the smartphone or is absent, then the 404 will be automatically notified to the next 404 proximity probation officer. The signal reception Ok function is equipped with Fail Over function, and the signal range can be defined within the range of 70m within the range area. In case of the disabled in the room, the indoor position is transmitted in real time through the AP installed at home In the case of an elderly person in the outdoors, there is a way to attach a beacon to a tool such as a cane or an electric wheelchair, This indoor and outdoor range change value can be confirmed by AP position information and LAI value, and it is possible to adjust the position recognition range or distance (up to 75m) as the set value through mode switching through it.

FIG. 5 is a drawing applied to a person subject to a probation by a court judgment.

509 The person subject to probation shall wear a restraint tool such as a bracelet or footrest and be warned when he or she is away from home at a certain distance or when approaching a specific area. This places the AP in the home of the probation observer and the position of the bracelet or footstep is transmitted to the probation server in real time, indoors or outdoors. In this case, LAI1 is set as the location of the set house, and LAI2 is set as the bracelet and footsteps. If the real distance and position of these two places become more than a certain standard, the warning server and the warning server can notify the guardian .

If the warning is ignored and LAI1 and LAI2 values are exceeded and the residence is out of range, the escape code is transmitted to the police officer at the most recent distance and the LAI2 position of the probation observer is transmitted to the police officer in real time. If the police officer can not receive the current Fail OVer function according to the route, Aram and Escape Code will be automatically transmitted to the next police officer in the street, and the mobile phone number, Mac address, and near AP ID In this case, the probation server operates a probation management server that manages the movement line, current position, and health status of the probation observer by a judgment such as a police officer and a court, And the total number of protected persons who have received the protection.

The numerals 01 to 08 following it are decimal numbers, The combination of Hex01 ~ Hex08 as in 703 is preceded by 03 and generates LAI code as 03_10011102120413051406150716081709.

The meaning of this LAI value is 1001 or 1011 depending on whether or not the place is moved as shown in 705, 1102 or 1112 depending on whether the place is stopped or not, 1204 or 1214 depending on whether the place range is changed or 1305 or 1315 , 1406 or 1416 depending on whether the current time is changed or not, 1507 and 1517 depending on the time range change, 1608 or 1618 depending on whether there is an error range, and 1709 or 1719 depending on whether or not the security code is applied. Is transmitted to the location information server LAI Converter and the location information server refers to the LAI value to convert the current beacon position to the information value. This information value is converted into the values of the current beacon state, distance, position, movement value, time, error tolerance, security, and the like.

8A and 8B are diagrams for explaining the LAI Converter in more detail. In FIG. 8, 801 is a value indicating a place movement, a place stop, a place range, a long axis coordinate, a time change, a time range, an error range, Based on the current time information, the current time information and the change time information are checked based on the current time information, and the set tolerance and the authentication value are determined based on the current moving time portion, the current stop portion, the current position range portion, The current error is checked and the current security value is checked.

The position of the current Bluetooth, the position of the access point and the coordinate distance information of the current smartphone are compared with the LAI Position, distance, time, proximate beacon information, etc. can be stored in the DataBase in real time with the above structure. The accumulated object position information is shown in Fig. 1 And the distance and coordinate information of the current access point's position.

The application direction of this information system can be applied as a management system for the probation observer by the simple disconnection. The biggest advantage is that it can be applied at home, indoors and underground The health status of the probation observer, the current location of the probation, the current location and route, and the emergency situation.

As described above, the handicapped and elderly care monitoring system stores the location of the home or the room of the disabled and the elderly in the probation server through the reprocessing of the beacon and the LAI through the LAI, It checks the health status or abnormality of the person to be protected through the sensor and bundles it as a pair. If an emergency occurs, it generates an emergency code and sends it to the smartphone of the probation officer at the latest distance. And the elderly in real time, health status, emergency situation and rescue, etc., which can constitute a system that can be used as a single information system, The logic, process, and construction methods that make up the invention It is characterized.

LAI = Locating Agency Information
Pair = Create two new values by combining two values
