The invention discloses a system and method for controlling an urban rail transit platform gap automatic compensation mechanism. The system comprises a turnover pedal, a turnover mechanism, a turnover motor, a turnover motor controller, an expansion-in-place detecting switch, a door controller and an upper computer, wherein the turnover pedal is mounted on the external side of a safety door threshold through the turnover mechanism; the turnover motor is positioned on one side of the turnover mechanism to control the turnover of the turnover mechanism so as to expand or retract the turnover pedal; the expansion-in-place detecting switch is positioned on the other side of the turnover mechanism; the turnover motor is connected with the turnover motor controller; the expansion-in-place detecting switch is connected with the door controller; and the turnover motor controller and the door controller are connected with the upper computer, respectively. According to the invention, as a platform gap compensator and a safety door are linked with each other, passengers are prevented from missing steps or dropping small articles to rails and the problem that the vehicle body may be scratched by a fixed platform gap compensator is solved; and the system and method for controlling the urban rail transit platform gap automatic compensation mechanism, disclosed by the invention, has the advantages of safety, reliability, convenience in use and good application prospect.
