Abstract

The invention discloses a circuit board autonomous fireproof method and system, a circuit board and an electronic device. The method comprises the steps of: collecting smog sensing signals in the working process of the circuit board; carrying out voltage signal analysis and processing on the smog sensing signals obtained by selection so as to obtain a fire monitoring result; and based on the fire monitoring result obtained by the voltage signal analysis and processing, and carrying out early-warning processing on a fire of the circuit board. The circuit board autonomous fireproof method and system, the circuit board and the electronic device have the advantages that the defects in the prior art that protection is incomprehensive and the electric safety is poor are overcome, and the beneficial effects of comprehensive protection and good electric safety are realized.

Description

technical field [0001] The invention relates to the technical field of circuit protection, in particular to a circuit board autonomous fire prevention method, system, circuit board and electronic device. Background technique [0002] In the current circuit board protection module, the most commonly used protection mode is to add a fuse to the main circuit, or to add a device that can independently detect arc faults and disconnect the circuit on the power cord plug at the same time - arc fault circuit breaker / leakage Fault protector (AFCI / LCDI). [0003] The above two protection modes can only play a protective role when the current in the main circuit meets the set conditions, and for the branch circuit (such as between component pins) the strong arc caused by the voltage difference will cause the circuit board to break down and burn , or even ignite the electrical box, and even the whole machine catches fire, as long as the main circuit current does not meet the setting co...
