Fire detection and smoke exhaust system for underground traffic conversion platform

Abstract

The invention relates to a fire detection and smoke exhaust system for an underground traffic conversion platform. The fire detection and smoke exhaust system comprises a control algorithm, a fire detection module, a fire retardance and extinguishment module and a ventilation and smoke exhaust module. The control algorithm can make decisions automatically in the stages of fire detection, fire retardance and extinguishment and ventilation and smoke discharge, but dispatchers can stop the algorithm at any time. The fire detection module judges whether a fire occurs and whether someone is trapped by monitoring environmental parameters of the underground traffic conversion platform in real time, and a control algorithm automatically decides the next action according to the monitored parameters. The fire arresting and extinguishing module adopts an automatic fireproof partition to seal a fire scene area, so that oxygen is exhausted to extinguish fire; after the control algorithm confirms fire extinguishing through the detection module, the ventilation and smoke exhaust module is automatically started to exhaust poisonous and harmful gas in a fire scene area. The fire extinguishing device is simple in structure, rescue of trapped persons is fully considered while quick fire extinguishing is carried out, and the safety is higher.

Description

technical field [0001] The invention relates to the field of fire protection of tunnels and underground projects, in particular to a fire detection and smoke exhaust system of an underground traffic conversion platform. Background technique [0002] The underground transportation conversion platform is a complex underground structure connecting the urban transportation network, usually composed of open sections connecting several connecting channels. Underground transportation conversion platforms are often important hubs in the three-dimensional transportation network. The traffic flow is large and the transportation organization is complex. Once a fire occurs, it will cause a huge threat to the lives of drivers and passengers, especially the irregular spread of toxic and harmful high-temperature gases will seriously hinder the crowd. Evacuate safely. In order to ensure the safety and efficient evacuation of drivers and passengers under fire conditions, the patent of the p...

Problems solved by technology

However, the structural size of related equipment and passages is relatively large, and it is not realistic to integrate them uniformly in the inflatable partition wall. Even if it is feasible, the design will be complicated and the stability has yet to be verified.
