A detection method for door clamps of a subway locomotive platform is disclosed. Whether a door body is subjected to rail side squeezing force is detected during a door closing process to confirm thatno clamp is present during door closing. After the door is closed in place, the pressure on the rail side of the door body and the pressure on the sill on the rail side of the platform door are detected, and the double confirmation is used to detect whether a person is clamped by the door or not, so as to achieve the purpose of automatic detection. Compared with the traditional anti-pinch methodof mechanical anti-pinch baffled, LED lamp bands and infrared light curtain systems, the detection method of the invention does not cause personal injury to passengers, has high safety, can be realized on the curved platform, has strong applicability, is not susceptible to vibration, dust or light interference, and is long in service life and high in stability.
