PURPOSE: A system for controlling a number of screen doors is provided to allow passengers to conveniently get on and off trains by opening and closing the number of screen doors according to a number of train doors. CONSTITUTION: A system for controlling a number of screen doors comprises an input and output part(120), a memory part(110), a train RF modem(130), a train control part(100), a ground RF modem(230), a train position detector(240), a PSD(Platform Screen Door) controller, a movable fixed-door driving device(251), a movable fixed-door opening and closing device, a fixed movable-door opening and closing device, and a PSD frame. The input and output part inputs engineer requirements in a train or outputs necessary information. The memory part stores information on train numbers, a number of trains, and a number of train doors. The train RF modem transmits the information stored in the memory part and receives the necessary information. The train control part transmits the information stored in the memory part to the PSD controller by the train RF modem, and receives the necessary information from the PSD controller. The ground RF modem receives the train numbers and the number of trains and train doors from the train RF modem. The train position detector calculates the speed of the trains and a distance to regular stop positions of the trains, and transmits the calculated information to train operators.
