Fire monitoring control system

Abstract

The invention discloses a fire monitoring control system. The fire monitoring control system comprises a temperature-sensitive detector used for acquiring a temperature value of an easy-to-burn source and emitting a first temperature alarm signal to a monitoring host when the temperature value surpasses the first preset alarm temperature value, a smog-temperature detector used for acquiring a smog-temperature signal value at the position of the easy-to-burn source and emitting a smog-temperature alarm signal to the monitoring host when the smog-temperature signal value surpasses a preset smog-temperature threshold, the monitoring host used for simultaneously receiving the first temperature alarm signal and the smog-temperature alarm signal, emitting a fire extinguishing processing instruction to a performing device and emitting an alarm processing signal to a conductor and a driver when only the first temperature alarm signal or the smog-temperature alarm signal is received, and the performing device used for carrying fire extinguishing processing according to the fire extinguishing processing instruction. Through the system, unnecessary fire extinguishing processing probability of an automatic fire extinguishing device caused by error operation of the smog-temperature detector or temperature-sensitive cables can be reduced, high accuracy and efficiency for fire monitoring are realized, and monitoring performance of vehicle fire monitoring control systems is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle fire monitoring, in particular to a fire monitoring and control system. Background technique [0002] In the current society, vehicles have become an indispensable means of transportation in people's lives, and people have higher and higher requirements for the safety performance of vehicles. For example, EMUs are a very common means of transportation. There are many heating devices such as cables inside the EMU. These heating devices usually generate heat during work, which may cause the temperature of the devices to be too high, or even cause a fire. If the conditions of these heating devices cannot be detected or dealt with in a timely and accurate manner, not only It will cause damage to train equipment, and even cause loss of life and property of passengers. [0003] Existing EMU fire monitoring and control systems are detected only through smoke detectors or only through temperature-sensing...

AI Technical Summary

Problems solved by technology

[0004] Although the existing technology can realize alarm and fire extinguishing, it is prone to false alarms

For example, factors such as passengers smoking and the failure of the smoke temperature detector itself can easily cause the misoperation of the smoke temperature detector, and factors such as the failure of the temperature sensing cable itself can easily cause the misoperation of the temperature sensing cable. In the case of accurate or false alarms, if the automatic fire extinguishing device directly extinguishes the fire, it may cause unnecessary damage to normal equipment and cause unnecessary panic to passengers

It can be seen that the monitoring performance of the EMU fire monitoring and control system in the prior art is low, which poses a threat to the safety of the EMU
