An automatic rescue system and evacuation guidance method based on pressure perception

Abstract

An automatic rescue system and evacuation guidance method based on pressure perception, the system is composed of a number of self-rescue devices connected to a server through wireless communication; wherein the self-rescue device is composed of a control unit connected to a number of pressure sensors; The control unit is composed of a micro-controller connected with a power supply module, a communication module, a GPS module, a speech synthesis module, an indicator light and a buzzer, wherein the speech synthesis module is also connected with a loudspeaker. The method includes: (1) system initialization; (2) the server performs segmentation and management of the ground area; (3) the self-rescue device enters an automatic rescue mode; (4) the server monitors the real situation of the crowd and enters an early warning / alarm state; (5) the self-rescue device Listen to the server command and enter the early warning / alarm evacuation guidance state. The present invention centrally manages large-scale crowds in closed border areas through modern network technology, so as to achieve effective evacuation of crowds and reduce safety accidents of dense crowds.

Description

technical field [0001] The invention relates to the technical field of public place safety, in particular to an automatic rescue system and an evacuation guidance method based on pressure perception. Background technique [0002] With the continuous improvement of social living standards, the masses are more and more enthusiastic about various entertainment activities such as square gatherings and large-scale concerts. Since the vast majority of public places did not consider the possible safety problems caused by dense crowds at the beginning of their design, most public places only have fire protection equipment such as fire hydrants without other safety protection measures. [0003] Due to the above-mentioned design flaws, in recent years, as crowds gather more and more frequently, stampede incidents have also occurred, and have caused considerable loss of life and property, such as the stampede on the Bund in Shanghai on December 31, 2014. [0004] At present, there are...
