Safety protection terminal and system with tumbling recognition function

Abstract

The invention discloses a safety protection terminal and system with a tumbling recognition function. The terminal comprises an acceleration sensing module used for obtaining acceleration of a user inreal time, a GPS positioning module used for obtaining position information of the user, a communication module used for sending information under control of a single chip microcomputer, an alerter used for issuing an alarm under control of the single chip microcomputer, and the single chip microcomputer used for obtaining acceleration amplitude and included angle by calculating based on the acceleration obtained by the acceleration sensing module, taking the acceleration amplitude and included angle as state eigenvalues of a human body, determining the current user status through threshold conditions of the state eigenvalues in different human states to conduct tumbling type recognizing, sending the fall recognition type and position information through the communication module, and controlling the alerter to issue the alarm. The safety protection terminal and system can provide good safety and security for the elderly, the disabled and the like. Recognition accuracy rate is higher,and false alarm is reduced.

Description

technical field [0001] The invention relates to electronic information technology, in particular to a safety protection terminal and system with a fall recognition function. Background technique [0002] Population aging is a global development trend, and China is no exception. According to research data, in China, 50% of the elderly over the age of 65 fall at least once a year. It can be seen that the proportion of falls in the elderly is quite high. According to the National Injury Surveillance System (NISS) data, falls / falls in the elderly aged 60 and above accounted for 50.53% of the injury cases. [0003] The existing fall detection methods are as follows: [0004] Zhuo Congbin, Yang Longpin, Zhou Lin and others pointed out in the article "Design of Fall Detection and Alarm System Based on MPU6050 Acceleration Sensor" that the module can be used to measure the acceleration of three axes and synthesize the acceleration to obtain the acceleration amplitude Furthermor...

AI Technical Summary

Problems solved by technology

However, the fall recognition algorithms established by these existing technologies are all to monitor whether they fall, and once they fall, they will call the police immediately, but falling is very similar to the user's spontaneous jumping movement, which may cause false alarms, and it is impossible to detect falls. inverted type for identification
