A traffic signal lamp automatic correction device and a traffic signal lamp system comprise a signal lamp automatic correction module and a control circuit, and the signal lamp automatic correction module comprises a signal detection circuit and a switching circuit; the signal detection circuit is used for detecting driving signals of signal lamps; the control circuit is used for judging whether the driving signal is an abnormal driving signal, and outputting a correction signal to the switching circuit if the driving signal is the abnormal driving signal; and the switching circuit is used for correcting the driving signal of the signal lamp according to the correction signal. The signal detection circuit can detect the driving signal of the signal lamp and send the detected driving signal to the control circuit, and the control circuit judges whether the detected driving signal is an abnormal driving signal or not and outputs a correction signal to the switching circuit if the detected driving signal is the abnormal driving signal; and the switching circuit corrects the abnormal driving signal according to the correction signal, so that the signal lamp can still work normally under the condition that the driving signal sent by the traffic signal controller is abnormal.

    一种交通信号灯的自动纠正装置及交通信号灯系统,包括信号灯自动纠正模块和控制电路,信号灯自动纠正模块包括信号检测电路和开关电路;信号检测电路用于检测信号灯的驱动信号;控制电路用于判断驱动信号是否为异常驱动信号,若为异常驱动信号,则输出纠正信号至开关电路;开关电路用于根据纠正信号,对信号灯的驱动信号进行纠正。由于信号检测电路能够检测信号灯的驱动信号,并将所检测到的驱动信号发送至控制电路,控制电路判断所检测的驱动信号是否为异常驱动信号,若为异常驱动信号,输出纠正信号至开关电路,开关电路根据纠正信号对异常驱动信号进行纠正,使得信号灯能够在交通信号控制机发送的驱动信号为异常的情况下,仍然能够正常工作。
