<p>According to the present invention, a laser distance measurement sensor system for a platform screen door (PSD) of an urban railway comprises: an electric train; a laser distance measurement device emitting and receiving laser to the electric train, and measuring a distance from a stop position; a TIP integrated control device receiving and correcting, and linearizing a data value of the distance measured by the laser distance measurement device; and a status and distance indicator indicating a stop position and a distance of the electric train corrected and linearized by the TIP integrated control device to enable crew driving the electric train to see the status and distance indicator, and to stop the electric train at the normal position. The present invention is economically efficient as the system includes a same performance level while the system has a lower purchase costs; and the system is compatible in communication between the products, including an interface function so as to be replaced for a previously used foreign product. Moreover, maintenance efficiency and convenience of use are improved to rapidly process failures.</p> |
