Nursing homes mainly serve the elderly, the elderly problem is more prominent. Because of the older age, the elderly more or less in the body some inconvenience, self-care degree is not as good as young people, more prone to accidents. The infrastructure construction of nursing homes is increasingly advanced, and generally there are gardens, fitness places, entertainment places, leisure places, etc. These facilities first enrich the life of the elderly, for the elderly's life to add light and color; It also brings potential inconvenience to the elderly. Because the place involves a large area, the management staff cannot take into account every old person in every position. When the old person has a problem, the service staff should find the location of the old person at the fastest speed and provide corresponding help.

Due to the large site and complex environment of the nursing home, the staff cannot timely locate and rescue the elderly in case of emergency, our company has designed and implemented a set of indoor and outdoor personnel positioning alarm system based on Zigbee: technology.

Introduction of the scheme:

Each old person is equipped with a positioning tag card, which is equipped with a ZIGBEE radio frequency card. The card is based on ZIGBEE wireless technology. Using the internationally common 2.4~2.5GHz frequency band, the tag card can actively send information to the outside world, and can transmit 0-1500 meters. After the information of the tag card is received by the base station, the base station can interpret the information in the card, and then know which old man's tag card number? Where is it? The base station then sends the information to the computer. When the elderly person moves to another location, the computer can monitor the location in real time.

When the elderly encounter difficulties anywhere in the floor, press the button on the tag card, and the computer screen of the management staff of the monitoring center will immediately display the location of the elderly, as well as the elderly's personal health status, disease and other relevant information, so as to provide guidance for the quick response and emergency help of medical staff.

Basic process of system implementation:

The base station of wireless positioning network is arranged in the rooms of the nursing home, and one base station is installed in 3-5 rooms. The area is the unit, and the built-in ZigBee module is used to provide data forwarding and routing functions, which is the routing node of the network. The collected signals are transmitted to the monitoring terminal over Ethernet.

The elderly should be equipped with a location tag, which has a built-in fall sensor. As the location node of identity identification, it has only identity and location information, and records the relevant information of the elderly in the terminal database.

The positioning base station passively receives the information transmitted by the tag, and the tag can choose to send data to the positioning base station from time to time or at intervals. The positioning base station receives and processes the information, and sends the information to the monitoring terminal.

Implementation function:

Automatic location report for the elderly

The label can be set to intermittently send information to the base station and report its location to the system. The system can monitor and manage all the elderly. When the information of an elderly person is not uploaded to the computer, the computer will pop up an alarm dialog box, prompting the management to check. The system will automatically depict the old man's movement path in a certain period of time.

Elderly SOS call

When the elderly encounter difficulties in any place in the community and press the emergency rescue button on the label, an emergency message will be sent to the base station, which will be transmitted to the computer in real time, and the computer will immediately display the location of the elderly, as well as the relevant information of the elderly's personal health status and diseases suffered by the elderly on the computer screen of the management staff. To provide guidance for medical staff in quick response and emergency help. At the same time, the real-time position of the staff can be monitored for standardized management and reasonable scheduling.

Fall alarm

The built-in fall sensor of the location tag will send alarm information to the monitoring center in time when the old person falls. The service staff of the monitoring center can query the location of the old person in time and treat the old person in time.
