Corridor anti-trampling early alarm and evacuation device

Abstract

The invention relates to a corridor anti-trampling early-alarm and evacuation device. The device comprises an emergency branch, an emergency host and a piece of remote equipment. The emergency branch is composed of a video collector, an audio processing module, a loudspeaker, a single chip microcomputer system, a memory, a trampling emergency button, a recovery button, an alarm lamp and an interface circuit. The emergency host is composed of the single chip microcomputer system, a video decoder, a video analyzer, a microphone amplifier circuit, an audio amplifier circuit, a phone alarm module, an alarm whistle, the alarm lamp, a network communication module, an interface circuit, a burst button, a monitoring screen, a mobile phone client, the microphone, a floor trampling indicator lamp and a monitoring loudspeaker. The remote equipment is composed of the network communication module, the single chip microcomputer system, a video switching circuit, a voice communication module, a monitoring screen, the alarm whistle, the alarm lamp, a trigger and a controller. The device is simple in structure and stable in performance. Automatic guidance and evacuation can be carried out when crowding occurs in a corridor. Safe evacuation can be carried out when trampling occurs in the corridor.

Description

technical field

[0001] The invention relates to a security device, in particular to an anti-stepped warning and evacuation device for corridors. Background technique

[0002] How to systematically, scientifically and efficiently prevent and evacuate corridor stampedes is a very important and urgent issue at present. At present, society and schools are teaching the parties how to avoid the stampede and how to save themselves after the stampede occurs, but there is no way to solve the problem of how to control, guide and evacuate the chaotic situation of the stampede in a timely and scientific manner in case of occurrence. After the stampede happened in the corridor, the people behind who didn't know the truth continued to move forward, and the people in front were curious about the situation behind, and even turned back to watch the excitement, causing the scene to be seriously out of control, which led to a very bad stampede. Among the existing technical solutions, there is...

Examples

Embodiment 1

[0019] Example 1: Information Collection and Identification

[0020] Under normal circumstances, the video collector 1 in the emergency extension of each corridor continuously collects the personnel flow information of the corridor in real time, and sends the collected information to the video decoder 11, and the video decoder 11 decodes the flow decoding information and sends it to the video Analyzer 12, the video analyzer 12 obtains the direction of action of the flow of people in the corridor and the approximate number of crowds through analysis, and temporarily stores them in the memory 5 .

[0021] Embodiment 2: anti-stampede warning

[0022] After the emergency host knows the direction and number of people flow on all floors within a unit time period, the single-chip microcomputer system 10 in the emergency host will read the corresponding dredging plan, and send different dredging voices to different floors through address codes, Complete real-time dredging in daily situations. Such as: when the single-chip system 10 learns that there are a large number of people going downstairs on the third floor, and when there are people going upstairs on the first floor, the speaker 3 on the first floor will play a voice such as: "There are a large number of people going downstairs on the third floor, please You stay close to the right, wait until he goes downstairs and then go upstairs"; and the speaker 3 on the third floor will play another similar voice: "There are people going upstairs on the first floor, please pay attention to avoiding them when going downstairs."

[0023] Embodiment 3: Stampede emergency treatment

[0024] When a stampede event occurs on a certain floor, once the stampede emergency button 6 of this floor is triggered, the emergency extension corresponding to the floor will quickly send an electrical signal to the emergency host. After the emergency host receives the signal, it will know the floor number of the trampled floor and start Emergency treatment mode: According to the flow direction of people in the corridor analyzed by the video analyzer 12, different alarm and evacuation voices are sent to each floor through the speaker 3; the siren 16 and the warning light 17 in the control room are triggered; the emergency host quickly activates the emergency evacuation mechanism, The draw ring in the described emergency evacuation mechanism drops to the stampede area by the reel and the motor, assists the personnel in the stampede area to evacuate quickly, and prevents the further deterioration of the trampled event; meanwhi...
