An intelligent belt and an intelligent fall emergency warning system

Abstract

The invention discloses an intelligent belt and an intelligent fall emergency warning system. A battery module of flexible material for power supply is installed in the belt body, and the control module is electrically connected with an acceleration sensor, an angle sensor and a pressure sensor for identifying a fall situation , the control module is also electrically connected with a wireless module. The invention is easy to carry, integrated and installed in the belt, without any attached feeling, conforms to people's wearing habits, combines mobile communication device, flexible battery, WIFI communication module indoor positioning and GPS outdoor positioning module, and information fusion detected by acceleration sensor and angle sensor , Judging whether the human body has fallen, the correct rate of judgment is extremely high; emergency avoidance can be carried out to protect the user at the moment of a fall, and reduce the probability of injury; when a fall occurs, timely rescue and follow-up wireless forecast can be provided to avoid falling. lead to more serious consequences.

Description

technical field [0001] The invention relates to the field of smart wearable devices, in particular to a smart belt with a smart fall emergency warning system. Background technique [0002] With the continuous development of communication technology, battery technology, position positioning and micro-sensor technology and the continuous progress of the information society, it is possible to develop convenient and reliable SOS alarms, fall alarms and position positioning devices. A positioning device that can automatically alarm when there are various accidental injuries inside, so that the injured can be treated in time. [0003] Nowadays, the problem of aging is becoming more and more serious. It is very necessary to design a positioning device for human body fall detection and alarm that is easy to wear and has no sense of attachment for the elderly over 65 years old or mentally handicapped people with inconvenient walking, mountain climbers, etc. [0004] At present, the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the main forms of devices with mobile communication functions are various handheld or wrist devices. There is no belt-type mobile communication device on the market. The power supply for mobile communication devices is mainly various hardware batteries, which cannot be bent at will; position positioning technology Mainly GPS positioning, there is usually no GPS signal indoors; commonly used technologies for fall detection include: ①Analysis of audio signals, fall events are judged by analyzing the frequency of vibration caused by impact, complex installation, easy misjudgment, and poor versatility

②Aiming at the image analysis of the video, the motion status of the object is monitored in real time through the camera, and the user's privacy is easily exposed

③ Based on the wearable detection device, the existing wearable fall monitoring is learned by analyzing the acceleration or obtaining the state of some devices (such as rotating devices), which has high requirements for the fall condition, single recognition condition, large power consumption, and is prone to misjudgment
