A locomotive fire prevention and control system

Abstract

The embodiment of the present invention discloses a locomotive fire prevention and control system, which includes: several fire detection subsystems placed in different fire prevention areas. The fire detection sensor; the control subsystem communicates with the fire detection subsystem, the locomotive computer network control system, the locomotive on-board protection system, and the ground locomotive remote diagnosis system. The control subsystem can be based on the detection data collected by each fire detection subsystem. Real-time logical judgment of the fire status of the fire prevention area where each fire detection subsystem is located, and execute and display corresponding processing actions based on the corresponding judgment results; and the fire extinguishing execution subsystem. Through the locomotive fire prevention and control system, the present invention can form a complete and closed-loop fire protection for the entire locomotive from fire detection, control judgment to fire extinguishing execution, and fully guarantee the safety of railway transportation.

Description

technical field [0001] The invention relates to the technical field of rail transit mobile equipment safety, in particular to a locomotive fire prevention and control system dedicated to railway locomotives and vehicles. Background technique [0002] Safety is the eternal theme of railway transportation, but with the rapid development of my country's railway transportation, the development of prevention and control systems that can ensure the fire safety of rolling stock is lagging behind. At present, my country's railway locomotives are not equipped with a complete fire prevention and control system in batches. Some Harmony locomotives are only equipped with locomotive safety protection systems (referred to as 6A systems) to monitor locomotive fires. Personnel confirmed and carried fire extinguishers to the fire source to extinguish the fire. [0003] Since the equipment compartment of the locomotive is a large fire protection area compared to the crew, it is difficult for ...

AI Technical Summary

Problems solved by technology

[0003] Since the equipment compartment of the locomotive is a large fire protection area compared to the crew, it is difficult for the crew to detect the fire at an early stage, and once the fire expands, it will be harmful to the crew to put out the fire with a portable fire extinguisher. Therefore, there are contradictions that the fire cannot be detected in the early stage, and the fire is too large and cannot be controlled.

In addition, the relative distance between the location of the fire extinguisher and the location of the fire, and the convenience of the driver and passengers cannot be predicted in advance. Portable fire extinguishers need to be manually operated by the driver and passengers. It is very high and requires a lot of training and exercises. At the same time, there will also be operation and maintenance problems such as fire extinguisher inspection, easy loss, and unclear accountability.

[0004] In recent years, although various local railway companies have successively installed some fixed water mist fire extinguishing devices on locomotives, they are all in the stage of independent operation and have not been linked with fire monitoring equipment and vehicle control systems, and cannot be transmitted to the locomotive remote diagnosis system for assistance through the network. Railway transportation scheduling; in addition, the fine water mist system has a large load capacity, cumbersome maintenance, and hidden dangers of short circuit and liquid leakage, which cannot effectively guarantee the safety of drivers and passengers and the safety of railway operations
