Alarm system for prevention of crowd treading

Abstract

The invention discloses an alarm system for prevention of crowd treading. The system comprises a human body obstruction device, a pressure sensing device, an alarm device, a power source device and a voice device, wherein the human body obstruction device also comprises a main air bag and a plurality of branch air bags which are installed and disposed outside the main air bag at an equal interval; and when the branch air bags are broken thanks to extrusion taking place in a crowd dense area, a spring of the pressure sensing device can stay at a stretched state, the power source device, the alarm device and the pressure sensing device can form a circuit loop, the alarm device can be started, and the voice device can send out a voice alarm announcement. The wearable human body obstruction devices are issued to people in a large-scale crowd collective activity, so that the alarm device in the human body obstruction device can send out alarm information when an emergency situation takes place in the crowd dense area. In this way, the objective of anti-treading alarming is realized. The system disclosed by the invention is characterized by simple, convenient and rapid operations and low cost.

Description

technical field [0001] The invention belongs to the technical field of alarm equipment and relates to an alarm system for preventing crowds from trampling. Background technique [0002] In recent years, in large-scale crowd collective activities, such as Hajj, large-scale celebrations and other activities, incidents of stampede caused by dense crowds have occurred from time to time, and there are currently two main ways to detect crowds, one using multi-sensor Monitor the flow of people in the case of side-by-side mode of people; the other uses video monitoring technology to count the flow of people. The common feature of the above two people flow detection methods is that the number of people can be measured more accurately, the measurement accuracy is relatively high, but the cost is relatively high, and when a dense crowd is detected, the relevant emergency center needs to be manually notified Activate the corresponding emergency measures. [0003] Therefore, how to ado...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes an anti-crowd stampede alarm system aiming at the problems existing in the prior art, the purpose of which is to reduce the defect of high cost of human flow detection technology in the anti-stampede alarm technology, and propose an anti-crowd stampede alarm system, which can be used in large-scale crowd collective activities In the human body blocking device for wearing, when an emergency occurs in a crowded area, the alarm device in the human body blocking device will send out an alarm message, so as to achieve the purpose of anti-stampede alarm, which is simple, convenient, fast and low cost. cheap and other characteristics
