TRAFFIC SIGNAL CONTROLLER AND SIGNAL DRIVING UNIT MOUNTED ON TRAFFIC SIGNAL CONTROLLER

摘要

PURPOSE: A traffic signal controller and a signal driving unit mounted on the traffic signal controller are provided to reduce an installation space and installation expenses of the traffic signal controller. CONSTITUTION: A communication unit(120) communicates with a main control unit of a traffic signal controller. A signal light driving unit(140) outputs a signal light driving signal for driving multiple signal lights including a red signal light and a green signal light. A control unit(110) controls the signal light driving unit according to a control signal from the main control unit of the traffic signal controller received through the communication unit. A first terminal(130) is connected to a control board. A second terminal(150) connects output from the signal light driving unit to a connection line of each signal light.
