Intelligent fire extinguishing system for electric locomotive

Abstract

The invention discloses an intelligent fire extinguishing system for an electric locomotive. The system comprises an intelligent fire extinguishing system mounted on the electric locomotive, and the intelligent fire extinguishing system comprises a miniature aerosol automatic fire extinguishing device, a wireless characteristic gas detector, a locomotive fire alarm controller and a wireless data transmission module. The system has the beneficial effects that a detection technology adopted by the system is an electric appliance fire characteristic gas detection technology, the system has the characteristics of early warning, low false alarm probability and reliable alarm, and meanwhile, by combining an autonomous temperature sensing detection starting technology of a fire extinguishing device, the reliable, safe and misoperation-free effects are achieved. The system adopts an intelligent fire-fighting design concept to combine the fireproof and fire extinguishing elements with the management, so that the real-time monitoring is realized. An existing vehicle safety system is combined with an Internet of Things technology, a safety site is organically connected with a management department and the related personnel through a narrow-band network information transmission technology, so that three early functions of early discovery, early disposal and early knowing of a fire are realized.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an intelligent fire protection system for electric locomotives. Background technique [0002] At present, the AC electric locomotives operating in the railway system are equipped with an on-board safety protection system (6A system), and the DC locomotives are equipped with locomotive fire monitoring devices. This kind of device uses point-type temperature-sensing detectors to detect the ambient temperature, and uses smoke detectors to detect whether there are smoke particles in the surrounding air. Early detection of fires. At present, the system used by the locomotive is only a fire alarm system, without linkage fire extinguishing and disposal equipment, and cannot automatically alarm and extinguish the fire. Even if a fire is found, the crew must operate the portable fire extinguisher carried by the locomotive to extinguish the fire. Comprehensive analysis has the fo...

AI Technical Summary

Problems solved by technology

[0003] (1) Due to the use of photoelectric smoke detectors and temperature detectors as fire trigger devices, during the operation of the locomotive, dust accumulation in the locomotive or water vapor atomization of the compressor often cause misjudgment by the detector and false alarm by the system

[0004] (2) The electric locomotive has a lot of equipment, complicated lines, and the interior space of the locomotive is very narrow, and most of the equipment and lines are installed in the electrical cabinet, and the cabinet door or protective cover is closed. The existing fire detection equipment cannot be detected first. Failure to report to the police and deal with them in a timely manner

[0005] (3) When a fire breaks out in a part of the locomotive, the crew needs to enter the machine room and other parts to make a judgment. To extinguish the fire, the crew needs to find the fire extinguisher equipped on the locomotive to manually extinguish the fire. For some parts that are prone to explosion due to fire, there are serious safety hazards for the crew

[0006] (4) The existing vehicle-mounted fire extinguishers are only 2 portable water-based fire extinguishers and 2 portable dry powder fire extinguishers. These two fire extinguishers have poor fire extinguishing effects on electrical fires, and the fire extinguishing dose is limited, especially water-based fire extinguishers cannot be used. Fire extinguishing for live electrical fires
