Distributed active fire extinguishing system for railway vehicle and control method

Abstract

The invention discloses a distributed active fire extinguishing system for a railway vehicle. The system comprises radiation type smoke and fire detection probes, spray heads, a water storage tank, anitrogen cylinder, an electromagnetic valve and a controller, wherein the number of radiation type smoke and fire detection probes and the spray heads which correspond one-to-one are the same; the radiation type smoke and fire detection probes are connected with the controller through cables, the spray heads are connected with the water storage tank and the nitrogen cylinder which are installed below the vehicle through a steel pipeline and the electromagnetic valve, and the electromagnetic valve is further connected with the controller at the same time; and the active controller is connectedwith a train network system, and is used for transmitting a temperature field in a guest room to the train network system and displaying the temperature field on a driver display screen, the controller controls the water storage tank and the nitrogen cylinder through the electromagnetic valve, water and nitrogen gas are filled into a steel pipe, the controller sprays high-pressure fine water mistto an ignition position by starting the corresponding spray heads, so that the active fire extinguishing is completed. According to the method, the accurate active fire extinguishing can be realized at an early stage when fire behavior is occurred, and a large amount of smoke generated during the fire can be sucked, a fire extinguishing agent is the water, and secondary damage caused to passengersand vehicles in the guest room does not happen.

Description

technical field [0001] The invention relates to the technical field of safety protection for passenger compartments of rail vehicles, in particular to a distributed active fire extinguishing technology. Background technique [0002] Inductive smoke and fire alarms are used to extinguish the fire in the passenger compartment of traditional rail vehicles. When the alarm detects a sufficient concentration of smoke and fire, the fire and fire alarm is triggered, and the crew or passengers use the on-board fire extinguisher to extinguish the fire. The whole process not only consumes precious fire extinguishing time At the same time, due to the lack of unified command and professional fire-fighting training for the fire scene, it is difficult to ensure that the fire can be quickly extinguished or controlled, and the smoke permeating the train cannot be controlled. The train does secondary damage. Contents of the invention [0003] The purpose of the present invention is to prov...
