Road traffic signal controller

Abstract

The invention discloses a road traffic signal controller. The road traffic signal controller comprises a main control module as well as a light-driven control center, a yellow light flashing control module and a servo system control center which are in communication connection with the main control module. The road traffic signal controller is characterized in that a current transformer circuit and a first voltage detection circuit are connected to the light-driven control center; an RJ45 interface module, an RS232 interface module, an RS485 interface module and a wireless communication modulewhich realize communication are connected to the main control module; a person walking button, a front door state switch and a rear door state switch are connected to the input end of the main control module; and the main control module communicates with wireless remote control equipment through a wireless communication module. The road traffic signal controller disclosed by the invention can realize current and voltage double detection and networking coordinated control of signal lights; by arranging the servo system control center, the signal controller can set information backup to ensuresystem security; and by arranging the yellow light flashing control module which is separately controlled by yellow light flashing, safe stable operation of the signal controller is ensured. The roadtraffic signal controller has the obvious beneficial effects and is suitable for application and popularization.

Description

technical field [0001] The present invention relates to a road traffic signal machine, more specifically, to a road traffic signal machine equipped with a servo system control center, a yellow flash control module, and capable of detecting the current and voltage of each signal light. Background technique [0002] Traffic signals ensure the smooth and safe operation of traffic at intersections. Smart traffic signals can alleviate traffic congestion. Once traffic signals fail, traffic at the entire intersection will be paralyzed, and chain effects will occur, affecting the normal operation of the entire road traffic. The types and functions of the existing road traffic signals are various, and there is no relatively uniform standard. For example, the existing traffic signals only have one set of control signals. Once a hardware failure or program operation error occurs, the traffic signal will be wrong or disappear. Bring great potential safety hazard to the traffic of whole ...
