Typical application of Internet of Things technology: elderly fall detection system
chrispeng [ad_1]
With the increasing trend of population aging, home care for the elderly has become a concern of all sectors of society. Coupled with the flow of modern young laborers, the elderly live separately from their children, weakening the function of the family to provide for the elderly, and the phenomenon of “empty nest elderly” has appeared. This phenomenon has made the problem of aging “exacerbated”. According to statistics, among the 167 million elderly people over 60 years old in my country, the “empty nest elderly” accounted for half. As the most prominent performance and one of the most severe challenges in this aging wave, the It has attracted great attention from the government and all sectors of society.
In response to the aging population and the “empty nest elderly” phenomenon, Xi’an Zhongxing Measurement and Control Co., Ltd. launched an elderly fall detection system to solve the problem of unattended elderly or “empty nest elderly”, and also hope to solve the problem of modern young people. He is busy at work, and worrying about the health and safety of the elderly in the family makes him feel at ease to go to work.
The elderly fall detection system can detect the movement status of the elderly at any time. When the status changes, it will send out an alarm message via GSM/GPRS to notify children or designated persons such as hospitals, communities, relatives, neighbors, etc. in time.
The elderly fall detection system is a true IoT product. The Internet of Things includes three parts: perception layer, transmission layer, and application layer. The sensing layer of the elderly fall detection system is a three-axis tilt sensor that senses the human body motion state, its transmission layer is a GSM/GPRS network, and its application layer is a mobile phone terminal that receives alarm signals. Therefore, the elderly fall detection system is a typical application of the Internet of Things technology.

Guardianship of the elderly in hospitals, communities, nursing homes, etc.
The product can also be used for:
Automatic alarm when sentinels, security guards, etc. fall in emergencies

5. Battery level reminder function
The red indicator on the surface of the product is a battery indicator. When the battery is fully charged, the red light will be off; when the battery is low, the product’s red indicator light flashes slowly and needs to be charged immediately; when the battery is exhausted, the product’s red indicator light flashes quickly, at this time, the sensor will turn off all functions .
6. Network signal prompt function
The green indicator on the surface of the product indicates the network status. When the green indicator light flashes quickly, it means that the product has not found a network signal. At this time, the product cannot send out an alarm message. When the indicator light flashes slowly, it means that the downer has been registered to the GSM network; in addition, when there is data transmission between the downer and the GSM network, the indicator light will flash frequently.
