The invention provides a signal lamp fault detection device which performs data transmission based on a direct-current power line carrier communication modulation and demodulation system, and a processor receives voltage loaded at two ends of a signal lamp and current flowing through the signal lamp detected by a detection circuit, and determines the working state of the signal lamp according to the received current and voltage. According to the embodiment of the invention, the modulation and demodulation system based on direct-current power line carrier communication accurately transmits thecurrent and voltage information of the signal lamp, so that the processor can accurately judge the working state of the signal lamp according to the received voltage and current, the working state ofthe signal lamp is judged, and the travelling safety is guaranteed.

    本发明提供了一种信号灯故障检测装置,基于直流电力载波通信调制解调系统进行数据传输,处理器接收到检测电路检测加载在信号灯两端的电压以及流经信号灯的电流,并根据接收到的该电流和该电压,确定该信号灯的工作状态。由于本发明实施例中基于直流电力载波通信调制解调系统,准确的传输信号灯的电流和电压的信息,从而可以使处理器根据接收到的电压和电流,对信号灯的工作状态进行准确的判断,进而实现了对信号灯工作状态的判断,保障了出行安全。
