Position identifying device for guiding people to scatter based on audio technology and control method thereof

Abstract

The invention relates to a position identifying device for guiding people to scatter based on the audio technology. A power source conversion circuit is connected with a CPU circuit, a voice amplifying circuit, a power amplifying circuit, a light emitting drive circuit and a broadband voice bank storage circuit. The CPU circuit is connected with the voice amplifying circuit, an output control circuit, a parameter setting circuit and a broadband voice band storage circuit. A control method of the position identifying device comprises the following steps that the CPU circuits of multiple position identifying devices receive a trigger signal at the same time, the CPU circuit of each position identifying device starts the corresponding position identifying device according to a parameter signal and calls voice information in the broadband voice bank storage circuit, and the corresponding position identifying device is controlled to make a sound and emit light. According to the position identifying device for guiding people to scatter based on the audio technology, position identification is achieved based on the audio technology, the problem that light rays of a light indicating identifying device are blocked after smoke diffuses, and therefore a safe position cannot be clearly identified can be effectively solved, and the probability of secondary disasters is reduced.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting linkage control in the subject of safety engineering, and relates to a personnel evacuation position identification device mainly used in various emergency situations in large-scale public buildings such as large shopping malls, stadiums, hotels, office buildings, and exhibition centers where people are densely populated and implementation methods. Background technique [0002] At present, the location recognition devices installed in large public buildings with densely populated places for evacuation are all visual indicators, that is, light indicators, such as safety exit sign lamps, evacuation staircase indicator lamps, etc. The outer surfaces of these lamps are all composed of patterns that mark the positions, and the patterns are irradiated with a certain light intensity to make the signs clearly displayed. In an emergency, when personnel see the sign, move quickly to the sign and then...

AI Technical Summary

Problems solved by technology

[0004] 1. Visual indicators such as safety exit sign lamps and evacuation staircase indicator lights are generally installed above the evacuation door or passage, with a certain height from the ground. When a fire occurs in a crowded place, the smoke spreads rapidly. When the smoke drops to a certain When the height is high, the indicator signs will be blocked, resulting in a reduction in the penetration of light, so that the evacuees in panic cannot clearly distinguish the signs of the safe location, and the safe evacuation location is likely to be missed during the evacuation, causing secondary disasters

[0005] 2. With the complexity of the structure of large public buildings and the diversification of functions, the passages and routes for evacuation of people tend to be more complicated, and crossroads or T-junctions often appear. Although there are many safe evacuation routes to choose from, it is very likely that The length of the evacuation routes from each safety exit is inconsistent, so the route randomly selected at the intersection may not be the best evacuation route, which will prolong the safe evacuation time of people and increase the risk of escape

[0006] 3. In densely populated places in large public buildings, the characteristics of the personnel are complex. For those with visual impairments, in an emergency, the light indicator signs cannot play a role in evacuation guidance, so it is easy to cause unnecessary personnel injuries and have a bad social impact
