The invention relates to the technical field of track detection, in particular to a bottom-contact type subway contact rail track detection system. The system comprises a detection system and a power supply system used for supplying power to the detection system, wherein the detection system comprises an encoder, a laser photoelectric sensor, a visual sensor, an upper computer, a distance measuring sensor and a programmable logic controller, wherein the encoder is connected with the programmable logic controller; the laser photoelectric sensor is in signal connection with the visual sensor and the programmable logic controller respectively; and the visual sensor is connected with the upper computer and the programmable logic controller respectively. According to the bottom-contact type subway contact rail track detection system, the structure is simple, detecting parameters are visual and effective, a detection method is simple, the responses speed is high, and early-stage character of contact rail faults can be reflected; and further, manual detection is replaced with automatic detection, the number of workers is small, the labor intensity is reduced, and the work can be finished by one worker.
