Elderly Fall Detector Radar Presence Sensing Designed for Falls

The elderly fall sensor radar presence sensing is specially designed for falls. The elderly have reduced body balance, fragile bones, and are prone to falls. Many elderly sudden diseases such as stroke and cerebral hemorrhage can lead to accidental falls. According to statistics, among the 300 million elderly people in China, accidental falls are the cause of death for people over the age of 65.

Whether it is a community pension or a family pension, children and caregivers cannot accompany them 24 hours a day. If an accident cannot be taken in time, it may be life-threatening. If the elderly have memory loss, mental decline, and can't remember phone numbers, they may also be lost. ,get lost.

It is a public consensus that the elderly cannot fall. After an elderly person falls, timely rescue is very important, but what should I do when there is no one around when the accident happens?

Today, Xiao Bian recommends a radar sensing elderly fall sensor specially designed for falls, which can be applied to various typical fall scenarios of the elderly, an intelligent sensor that recognizes the fall of the elderly, and escorts the elderly safely.

Once the elderly falls and faints, the elderly fall sensor can immediately sense and notify the caregiver or family members, and push relevant information, so that emergency measures can be taken in time.

Radar induction is an electronic device that uses electromagnetic waves to detect targets. By emitting electromagnetic waves to illuminate the target and receiving its echoes, it can obtain information such as distance, distance change rate (radial velocity), direction, and angle. The radar sensing distance is long, the angle is wide, there is no dead zone, and it can penetrate glass, thin plates, etc. At the same time, radar sensing is not affected by environment, temperature, dust, etc. under normal working conditions.

Falls in the bathroom account for 41.67% of the total falls of the elderly, and almost 20 million elderly fall in the bathroom every year. Therefore, the bathroom in the house is the most prone to accidents for the elderly: tripping due to kicking the threshold, slipping and slipping on the ground, sitting for a long time on the toilet, squatting for a long time, fainting, taking a long bath, unstable center of gravity, falling, etc. Wait.

A safe and convenient smart radar sensor is an important guarantee for the elderly at home, especially for the elderly at home. It would be even more thoughtful if they could accidentally fall and automatically send out an emergency call for help.

The radar has strong performance, rich algorithms and strong scalability, which is suitable for high performance requirements. It supports standard UART interface, can be connected with other masters or sensors, and can also be used as masters to realize presence sensing based on human breathing detection.

The non-contact elderly fall sensor can be installed on the top of the toilet for the elderly. Doppler detection and other technologies are integrated. Through data analysis, it can judge the normal behavior of the elderly entering and leaving the toilet, sedentary, sitting, lying, etc. in the toilet, and real-time through the network. Send safety information, early warning information and emergency alarm information to the platform and related personnel, which is more user-friendly.

In recent years, my country has attached great importance to the investment in the elderly and human resources, which has promoted the rapid development and application of science and technology, provided technical support for elderly services, and fully reflected the people-oriented governance concept. With the upgrading of hardware technology, the elderly fall sensor can realize the combination of sensing and communication, embedded in hardware devices and other advantages, so that intelligent development has strong practicability and broad application prospects.
