Method and controller for preventing automobile spontaneous combustion

Abstract

The invention discloses a method and a controller for preventing automobile spontaneous combustion. The method comprises that: the prior automobile electrical-apparatus control system is adopted; a voltage-variable relay which is started as soon as electrical apparatus is short-circuited and the voltage drops is designed on a power bus of the prior automobile electrical-apparatus control system; the voltage-variable relay detects of the electrical apparatus and lines of a whole automobile in real time; when the electrical apparatus or a wire is short-circuited and the voltage is in an unstabledropping state, the voltage-variable relay outputs a group of relatively stable power supplied to an alarm system and an outage operating system so as to achieve the aims of protecting the electricalapparatus and the lines and preventing the occurrence of automobile spontaneous combustion. The invention has the advantages that the controller is connected with an automobile circuit in a conditionwithout changing the prior automobile lines, has a detecting-monitoring system capable of monitoring the states of electrical-apparatus lines in real time, performs intelligent recognition, voice-sound-light alarming and whole-automobile centralized control, is simple and effective in operation of controlling automobile spontaneous combustion, and instantly gives sound-light alarms in case of short circuits of the electrical-apparatus lines so as to effectively control situation in time and prevent the electrical-apparatus lines from burning down and avoid automobile spontaneous combustion.

Description

technical field [0001] The invention relates to an automobile spontaneous combustion protection technology, in particular to an automobile spontaneous combustion prevention method and a controller. Background technique [0002] The culprit of spontaneous combustion in a car is caused by a short circuit of electrical appliances or wires. When a short circuit occurs in electrical appliances or lines, the current in the line increases sharply instantly, and a steady stream of current passes through the short circuit point. At this time, the core of the wire turns red from heat, and the wire sheath is quickly ignited to form an open flame. 98% of the items in the car The above are flammable materials, which will burn immediately when exposed to an open flame, and will quickly cause a fire. [0003] For a long time, TV stations, newspapers, and the Internet have often reported car spontaneous combustion incidents. A car that was driving normally caught fire and could burn the ca...
