Protecting and alarming device and use method thereof

Abstract

The invention discloses a protecting and alarming device and a use method of the protecting and alarming device. The protecting and alarming device comprises a waistcoat which comprises four annular inflation channels and is made of elastic materials, a state sensor, four gas bomb electromagnetic starting devices, four gas bombs and a mobile phone client side. The channels are externally connected with the gas bombs. The state sensor covers the chest part of the waistcoat and is internally provided with an acceleration sensor, a single-chip microcomputer and a Bluetooth module. The four gas bombs are connected with the gas bomb electromagnetic starting devices and are internally provided with compressed carbon dioxide gas. The mobile phone client side receives data, starts positioning and sends alarming information to family members of a user. According to the protecting and alarming device and the use method of the protecting and alarming device, the body state can be detected through the acceleration sensor at the chest part, the single-chip microcomputer is used for calculating acceleration data to judge weather falling happens or not, if yes, the gas bomb electromagnetic starting devices are triggered to start the four gas bombs, and the four gas bombs are connected with the four inflation channels of a coat respectively. The waistcoat is inflated to reach a certain thickness to ensure that the back, the chest and the head of the user cannot collide with the ground surface after the user falls, and meanwhile signals are sent to the family members of the user through mobile phones.

AI Technical Summary

Problems solved by technology

The device is relatively inconvenient to carry, and it is relatively slow to inflate with only one inflatable bottle, and the relatively long response time for opening the backpack is not conducive to better protection for the user. It may happen that the user has fallen but is not fully inflated. The device cannot protect people more comprehensively, and the airbags are scattered, which may bend the user's torso and cause injury
