1. Application background
With the rapid expansion of the problem of population aging, the issue of elderly care for the elderly has received widespread attention and concern from the government and society. In order to enable more elderly people to enjoy their old age, more and more elderly care institutions have been built. In order to ensure the safety of the elderly in nursing homes and other institutions, so that the elderly can enjoy more comprehensive and considerate services, it is necessary to use technology to provide real-time care for the elderly, and to be able to detect and rescue the elderly when they encounter emergencies. .
At present, in nursing homes and elderly communities, traditional wired call systems are commonly used to solve the problem of rescue for the elderly. Because the technologies used in these devices are relatively old and backward, there are many problems in the actual use of the timeline:
The pager is fixedly installed on the wall, which is inconvenient to use. When the elderly encounter an emergency (such as a fall or a sudden heart attack), they often have difficulty moving. If they are far away from the beeper, they will not be able to send a signal for help in time.
The call system is limited to indoor use, and cannot be effectively monitored when the elderly are active outdoors.
Unable to realize active care, unable to intelligently analyze the physical signs of the elderly, so as to discover possible dangers and hidden dangers.
The location of caregivers cannot be located, and system resources cannot be effectively integrated.
2. System introduction
The elderly apartment personnel positioning help system (this system) adopts the international leading ZigBee wireless communication technology, which can realize real-time and full-scale care of the elderly, and can effectively integrate the existing care resources, which can fundamentally solve the traditional elderly call Many problems exist in the system. The main features of this system include:
Full-range seamless monitoring: Every elderly person carries a positioning card with him, and the active position of the elderly can be monitored in real time, whether indoors or outdoors. System signal coverage is comprehensive, no dead ends.
The system responds in time: When the elderly need help in an emergency, they can use the location card to call for help at any time. The response time is less than 3 seconds.
Intelligent analysis: Intelligent analysis can be performed on the behavior of the elderly, and early warning of possible dangers. For example, when the elderly stay in the bathroom for a long time, the system can issue an early warning.

When an elderly person asks for help, the system can display the caregivers closest to the elderly person for help, so that the elderly can get them in the shortest possible time. For help.
Convenient installation and modification: The system equipment adopts ZigBee-based wireless MESH self-organizing network wireless technology, no wiring is required during construction, which can effectively reduce the difficulty and cost of initial installation, especially system transformation.
Complete management platform: In addition to real-time management functions such as seeking help for the elderly, the system can also establish a complete elderly information database, which can be integrated into the database for each elderly’s physical condition, personal preferences, medical history information, etc.
All-in-one card integration: In addition to the function of locating help for the elderly, the locator card can also expand the functions of electronic consumption and electronic access control.
