Line protection and fire fighting system of vehicle

Abstract

A line protection and fire fighting system of a vehicle comprises a switching circuit and an over-current protection circuit. The switching circuit is in series connection between an automobile storage battery and an automobile current-using device, and controlled by the over-current protection circuit to connect and disconnect the power supply line of the automobile storage battery. The over-current protection circuit monitors the current on the power supply line of the automobile storage battery in real time, determines whether the monitored current value exceeds a current threshold value or not, and controls the switching circuit to connect and disconnect the power supply line of the automobile storage battery according to the determination result. The system further comprises a remote control emitter, a remote control receiver and an extinguisher with an electronic control switch, wherein the remote control receiver controls a driving circuit to supply power for the electronic control switch when receives a remote control signal, and the electronic control switch starts the extinguisher to work. According to the system, not only potential fire danger is preventively eliminated, but also flames can be extinguished timely, reliably, quickly and completely, and simultaneously, the normal start of the automobile is not affected when the start bus of the automobile is under control.

Description

technical field [0001] The invention relates to a vehicle line protection and fire-fighting system for preventing vehicle line short-circuit fire. Background technique [0002] Cars are already a common means of transportation, which brings a lot of convenience to people, but spontaneous combustion of cars is also a potential killer, which poses a huge threat to people's lives and property safety. Most of the reasons for spontaneous combustion of automobiles are the short circuit of the automobile circuit or the burnout of electrical components, which causes the spontaneous combustion of the vehicle, or the damage of the line insulation caused by the impact of the vehicle, so that the positive pole is directly grounded and causes a fire. The spontaneous combustion caused by the short circuit of the automobile, although the engine It will stop running, but the starting battery of the car still has huge electric energy, which continues to supply power to the vehicle circuit, s...

Problems solved by technology

However, this kind of automatic fire extinguishing device that automatically controls the work of the fire extinguisher by the sensor has potential safety hazards. Due to the complex working environment of the vehicle, the automatic fire extinguishing device is prone to malfunction. For example, sudden spraying in the driving cab of a vehicle will block the line of sight and cause traffic safety accidents; moreover, the reliability of the automatic fire extinguishing device cannot be guaranteed to be 100%, resulting in the failure of the fire extinguisher to spray out fire extinguishing materials in time, etc.
