Smart fire scene escaping system and evacuating method for large-scale exhibition halls

Abstract

The invention discloses a smart fire scene escaping system and evacuating method for large-scale exhibition halls. The system comprises a monitoring system for obtaining the onsite information of a fire scene; a handheld terminal and a sound-and-light indication device for guiding the escape of people; and a control terminal for receiving the data from the monitoring system and issuing escape routes to the handheld terminal. The monitoring system comprises M fire detectors, N infrared cameras, and L audio frequency acquisition cards. The handheld terminal comprises a processor pre-stored with the emergency channel map for the large-scale exhibition hall. The I / O disconnection interface of the processor is electrically connected with a positioning chip. The sound-and-light indication device comprises a sound-and-light alarming device and an audio player. Each door of the emergency channel is provided with at least one sound-and-light alarming device and one audio player. Each sound-and-light alarming device and each audio player are provided with a wireless communication module respectively. The processor is provided with a wireless communication module and a display module. The control terminal comprises a main controller and a standby controller.

Description

technical field [0001] The invention relates to the technical field of fire escape equipment, in particular to an intelligent fire escape system and an evacuation method for large exhibition halls. Background technique [0002] As we all know, fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of civilization progress. Therefore, the history of human use of fire and the history of fighting against fire go hand in hand. Fire usually refers to a burning phenomenon that occurs or expands against human intentions, and eventually loses control in time and space and causes property and personal injury. According to fire losses (casualties, number of affected households and direct loss of property), they are divided into general fires, major fires ...

Problems solved by technology

[0003] In a large exhibition hall, due to the dense population, once a fire breaks out, how to quickly and effectively evacuate the people in the large exhibition hall to a safe location has always been the focus of attention of firefighters and related scientific researchers. At present, the traditional evacuation equipment is mainly The evacuation indicator light and fire alarm fixed on the wall, once a fire breaks out, the people in the large exhibition hall will swarm in one place according to the evacuation indicator light, which is very easy to cause a stampede accident; at the same time, the situation at the fire scene changes rapidly, sometimes A fire will break out in the evacuation channel, so the evacuation instructions are likely to lead people to a dangerous escape route. Therefore, it is necessary to design and develop an intelligent fire escape system and evacuation system that can adjust the evacuation route in time according to the real-time situation of the fire scene. method appears to be particularly important
