In recent years, there has been a lot of research on nursing measures for elderly patients with diseases, but there is less management of elderly care and safety measures for elderly in nursing homes. Beijing Chuangyi Xingsheng Technology Development Co., Ltd. uses technology to analyze the daily life status, behavior and elderly care of elderly in nursing homes. In view of the current nursing situation, an intelligent management system for nursing homes has been developed to improve the quality of nursing services and improve the quality of life of the elderly.
1. System introduction
1.1 System Introduction
This system is a complete and efficient intelligent management system developed by using wireless sensor network and RFID radio frequency identification technology, by installing RFID hardware and corresponding functional software, aiming at the actual situation of the management of the elderly.
1.2 System characteristics
(1) Advanced RFID equipment technology
RFID active tag technology can read data through external materials; it has a long service life and can work in harsh environments; it has a longer reading distance; it can write and access data, and the writing time is fast; the content of the tag can be dynamically changed It can handle multiple tags at the same time; the data access of the tags is protected by a password, and the security is higher; it can track and locate the objects attached to the tags.
(2) The system has a high degree of maturity
It has the characteristics of low cost, low power consumption, stability and confidentiality, and can run independently without relying on other systems. Fully consider the reliability and security design of the network, host, operating system, database, etc.
(3) Good compatibility and scalability
It adopts advanced computer application technology and has good expandability. The open architecture and long-term life cycle can meet the needs of future development of new functions; the data obtained by the system through GPRS or serial port can be seamlessly connected with the system.
2. System introduction
2.1 System overview
1) Distribute a key card type label or key type wristband label for each elderly person. The label stores a unique ID number as the unique identification of the person. It can also store the simple information of the person: name, apartment, room, etc., contact Methods, information about children, etc.;
2) Install omnidirectional card readers on important roads and lakesides in the community to realize personnel positioning and determination.
3) Through the recording of the information read by the omnidirectional card reader, it is possible to locate all the elderly in the area. By connecting the readers that all the elderly pass through, you can know the approximate route that the person has passed by, and support historical trajectory query.
4) Deploy a directional card reader at the entrance and exit of the community to realize the functions of determining the entrance and exit of the elderly and recording the entrance and exit time of the elderly.
2.2 Equipment layout
1. The small red dot represents the omnidirectional card reader (to achieve personnel positioning)
2. The pink rectangle represents the directional card reader (determine people entering and leaving the community)
3. The green hexagon represents the coordinator (accepts all the information from the directional card reader and uploads the data to the host computer)

2.4 Function realization
2.4.1 Elderly management
Distribute a card tag or wristband tag to each elderly person. The tag stores a unique ID number that can uniquely identify the elderly person. It can also store simple information about the elderly: name, apartment, room, etc., contact information, and children’s information Etc.; other detailed information is stored in the back-end database corresponding to this ID number for management personnel to query and access.
Because the card tag is active and sends signals all the time, every elderly person holding the card tag will read the content of the tag when he enters his work area.
When the card reader reads the information, it sends the data to the upper computer of the system through the communication interface, and compares it with the information of the old man in the upper computer: if the information of the old man matches the information in the background database, it can be entered smoothly;
Timely count the information of all the old people in the community. If the old people have physical or other conditions, they can press the button to alarm, and the monitoring center can immediately know the location information of the old people.
Video linkage function can be selected. After a button alarm occurs, the system analyzes the location of the old man and automatically calls nearby cameras to check the situation.
2.4.2 Whole-process regional positioning
When each elderly person holding an electronic card tag enters the corresponding area, the omnidirectional card reader on each road reads the tag, determines which area he is in, locates it, and the card reader sends the elderly person through the communication interface. The information is sent to the upper computer at the control end, and the upper computer records the movement trajectory of the elderly, and can locate the area of the elderly. The monitoring personnel can query the location of an elderly person’s area through the upper computer.
2.4.3 Button alarm
Each wristband tag and card-type tag has a button. If the old person has a physical condition, the old person can call the alarm by pressing the button. The alarm signal will be sent to the monitoring center through the omnidirectional card reader, and its location will be displayed on the electronic map. And through the intercom system to notify nearby staff to check in the past.
2.4.4 Viewing the travel route
When an elderly person holding an electronic tag passes through a card reader arranged in each area, the card reader will record the information and appearance time of the tag at this time. Connect these passing card readers to know the approximate route of the person.
2.4.5 Records of entering and leaving the community
After the elderly with electronic tags pass the entrance and exit of the community, the system will automatically record the time of entry and exit of their electronic tags, the name of the elderly, etc., for later query.
