Heart rate-based fall detection method and system

Abstract

The invention relates to a heart rate-based fall detection method and a heart rate-based fall detection system applied to a wearable electronic device. The system comprises an air pressure unit, a heart rate unit and a fall unit, wherein the air pressure unit is used for starting an air pressure detection function to acquire a relative height difference; the heart rate unit is used for starting heart rate detection if the relative height difference is larger than or equal to a preset height difference threshold; and the fall unit is used for sending a fall alarming signal when the heart rate change value is detected to be larger than or equal to a preset heart rate change threshold. Thus, according to the heart rate-based fall detection method and the heart rate-based fall detection system applied to the wearable electronic device, through detecting the air pressure to trigger heart rate detection, a condition in which an old person does not wear the detection terminal on the body can be eliminated, whether the old person falls can be intelligently judged more accurately, timely help is given, practicability is strong, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of wearable electronic devices, in particular to a heart rate-based fall detection method and a heart rate-based fall detection system applied to wearable electronic devices. Background technique [0002] With the rapid development of wearable electronic devices, more and more elderly people have also become loyal users of wearable electronic devices. Wearable electronic devices, such as smart watches, can solve the safety problems of most elderly people, especially for empty nest elderly or elderly people who go out alone, wearable electronic devices can play a very critical role. Under normal circumstances, wearable electronic devices use air pressure sensors or motion sensors to detect falls. When an elderly person is detected to fall, an alarm will be sent to the family members of the elderly in time to help the elderly faster. However, because sometimes the old man does not wear the smart watch, but ac...

Problems solved by technology

However, because sometimes the old man does not wear the smart watch, but accidentally drops the smart watch on the ground, or because the old man's hand shakes, the smart watch is dropped during the wearing process.

However, the above two kinds of elderly people did not really fall, and the smart watch will still send out an alarm message, causing certain troubles to the family members of the elderly. It can be seen that the current wearable electronic devices cannot accurately alarm
