Fall alarm, fall alarm detector and fall alarm detecting method

Abstract

The invention provides a fall alarm, a fall alarm detector and a fall alarm detecting method. The fall alarm comprises an MCU (microcontroller unit), a sensor unit, a GSM (global system for mobile communications) wireless unit, a display unit, a push-button unit, an alarm unit and a Bluetooth unit. The sensor unit, the GSM wireless unit, the display unit, the push-button unit, the alarm unit and the Bluetooth unit are connected with the MCU. The sensor unit comprises a 3D (three-dimensional) acceleration sensor for detecting the acceleration of a user and an air pressure sensor for detecting air pressure data. Through the data acquired by the 3D acceleration sensor and the air pressure sensor, the moving-down state, state of weightlessness and collision state of the body center of gravity of the user can be detected accurately, and misjudgement is less easy to occur. When the user is judged to fall down, the fall alarm operates timely, and accordingly injuries of unattended patients or old people can be reduced to the lowest level.

Description

technical field [0001] The invention relates to fall detection, in particular to a fall alarm device, a fall alarm detection device and a method. Background technique [0002] With the rapid development of the 21st century, the environment has been greatly threatened, and people's pace of life is getting faster and faster. Health, especially the health of the elderly, is a problem that cannot be ignored. Due to the acceleration of young people's life and work, usually the sick or elderly at home are left unattended, so that emergencies cannot be dealt with in time. Falls are a clinical problem worthy of attention for the above-mentioned population. In addition to physical injuries, falls may also cause serious sequelae in psychology, physiology and social life. Therefore, it is of great practical and social significance to develop an intelligent fall detection and alarm system. [0003] Now there are mainly the following types of products: [0004] A> mercury switch ty...

AI Technical Summary

Problems solved by technology

[0009] This type of fall detector judges whether an alarm is required by comparing whether the inclination of the human body is greater than the threshold, and the results are often inaccurate

[0010] The above-mentioned several fall detectors are often not accurate enough, nor smart enough to accurately judge whether the user has fallen, nor can they automatically and quickly send a help signal after the user falls.

This is undoubtedly very inconvenient for unattended patients or the elderly
