Abstract

The invention relates to a signal lamp control switch protecting circuit and an adaptive protecting method thereof, wherein compared with the prior art, the signal lamp control switch protecting circuit and the adaptive protecting method thereof are advantageous by overcoming a defect of incapability of performing adaptive protection on a signal lamp control switch. The adaptive protecting method comprises the following steps of performing real-time detection on an AC voltage magnitude; determining the state of the AC voltage magnitude; processing a first-grade alarm range, uploading the fault and storing a detected value by a signal lamp microcontroller module; processing a second-grade alarm range, and performing voltage protection by the signal lamp microcontroller module according to state of a signal lamp set; and processing a third-grade alarm range, transmitting a switching-off control signal by the signal lamp microcontroller module through a first control signal output end, a second control signal output end and a third control signal output end, and making a red lamp control switch, a yellow lamp control switch and a green lamp control switch in an off state. According to the signal lamp control switch protecting circuit and the adaptive protecting method thereof, through adaptive adjustment on the signal control system, switching frequency and fault frequency of the signal lamp control switch in a strong interference environment are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of signal light control switches, in particular to a signal light control switch protection circuit and an adaptive protection method thereof. Background technique [0002] The signal control system is the most basic and core functional unit in the field of intelligent transportation. Due to the rapid development of infrastructure such as road traffic in my country, large-scale power projects such as foundation construction often occur at many intersections, which affect the voltage stability of the intersection and increase the signal. The failure rate of the control system. [0003] In the current traffic signal control technology, the method of real-time detection of the current working state is adopted for the failure of the signal light control circuit. This method can only detect the problem after the fault occurs, and cannot protect the relevant functional components before the fault occurs, so that w...
