The invention provides a signal lamp color acquisition device and a working method, and the system comprises a signal lamp monitoring unit which is used for collecting pulse signals of each group of signal lamps in a traffic signal controller according to a preset period; the calculation and analysis unit is used for acquiring a lamp color state and a lamp color period of each signal lamp according to the pulse signals of the signal lamps, and calculating countdown information of each signal lamp according to the lamp color period; and the data transmission unit is used for transmitting the lamp color state and the countdown information of each signal lamp to a rear-end platform in a wired or wireless manner according to a preset format. Real-time lamp color states of the signal lamps are collected and learned through the high-compatibility signal lamp color collecting device, the device is simple in overall structure and low in cost and is not affected by weather, light or angles, the problem that equipment is insufficient in compatibility with signal machines of different brands can be solved, and the device is suitable for popularization and application. The accuracy and reliability of signal lamp color acquisition are improved.
