The invention discloses a lamp control board circuit of an intelligent traffic signal controller. The circuit comprises a single-chip microcomputer minimum system (1), a Hall sensor circuit (2), an optocoupler silicon controlled rectifier drive circuit (3), a 220V voltage detection circuit (4), a relay circuit (5), a voltage amplification filter circuit (6), a CAN bus communication circuit (7), anRS-485 communication circuit (8), a hard yellow flashing signal circuit (9), an LED traffic light display circuit (10) and a system indicating lamp circuit (11). The optocoupler silicon controlled rectifier drive circuit (3) can effectively control 220 alternating current passing through the optocoupler silicon controlled rectifier drive circuit (3) through an optocoupler control silicon controlled rectifier so as to realize light flashing control of the traffic light. The circuit can be used for instruction receiving, instruction response and LED traffic light intelligent control, the LED traffic light can be controlled in combination with a specific light control program, the time of the traffic light is reasonably adjusted according to the passing condition, and the circuit has application value in the field of road traffic.
