Intelligent evacuation guide system for fire and gas leakage, and communication method thereof

Abstract

The invention discloses an intelligent evacuation guide system for fire and gas leakage, and a communication method thereof. The system comprises a plurality of evacuation guide terminals, one evacuation guide gathering terminal and one industrial control computer, wherein each evacuation guide terminal node consists of a detection sensor, a wireless communication module and a direction indicating lamp. The detection sensors collect the fire or gas diffusion degree at a place, and transmit the fire or gas diffusion degree to the evacuation guide gathering terminal through a wireless self-organizing network, and then the evacuation guide gathering terminal communicates with the industrial control computer. The industrial control computer makes a reasonable evacuation route according to a floor map, and transmits the direct information to each node. The indicating lamps in the direction of each node changes correspondingly, so as to indicate the change of the evacuation route. The system has the functions of the self-organizing network and a jump function. If the network nodes are arranged in a range where the network nodes can communicate with each other, the network nodes can carry out the automatic search mutually, thereby forming an interconnection network. The system is good in flexibility, is safe and reliable, and is high in intelligentization degree.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an intelligent evacuation guidance system for fire and gas leakage and a communication method thereof. Background technique [0002] The research on intelligent evacuation system has always been highly valued by various countries. Research on intelligent evacuation in Europe, the United States and other countries and Japan started earlier, developed rapidly, and is currently in a leading position. Although our country started late, there are also some companies whose products are at the leading level in the industry. Japan's evacuation indication system has developed rapidly, and there are two representative research results: 1. Light flashing mobile evacuation indication system. 2. An evacuation system using the preceding sound (Haas effect). The two use the flashing lights and sound prompts respectively to guide the victims to escape in the direction of the safety ex...
