Abstract
The utility model discloses an intelligent traffic signal controller, and the controller comprises a processing module, a signal lamp emergency switching-off module, and an alternating-current electrical interface. The alternating-current electrical interface is connected with the current input end of the signal lamp emergency switching-off module, and the current output end of the signal lamp emergency switching-off module is connected with a green light. A first output end of the processing module is connected with the control end of the signal lamp emergency switching-off module, so as to control the connection or disconnection of the signal lamp emergency switching-off module for controlling the power supply of the green light and a red light. The power supply of the green and red lights can be switched off automatically when a power-off fault happens to the red light or a normally-on fault happens to the green light, so as to avoid a wrong traffic signal command, and completely eliminate hidden troubles of traffic accidents. In addition, the controller has a function of zero-crossing detection, thereby enabling the change of a driving signal to be in a roughly zero-crossing state of an alternating current, and improving the driving stability of a silicon controlled rectifier. Moreover, the controller provided by the utility model also has a function of peak detection, and can improve the stability of fault detection.
