Light train control system applied to oversea freight railways

A light train control system applied to oversea freight railways, the system integrating automatic block, station turnout control and train operation overspeed protection control and comprising an on-board subsystem, an RBC subsystem and a satellite positioning differential base station management subsystem, wherein the on-board subsystem is respectively connected to the RBC subsystem and the satellite positioning differential base station management subsystem by means of on-board equipment external interfaces;

• the light train control system adopts two-way continuous train-ground wireless communication and uses on-board signals as main signals of train operation to control the train operation;
• meanwhile, the system monitors the train operation, so as to provide an alarm to a driver when the situation changes, and to brake a train when necessary;
• and the system uses an electronic map to manage line data of a whole line, achieves dynamic configuration of the transport capacity by means of a virtual block technology, and remotely controls basic signaling equipment by means of an RBC,
• wherein the on-board subsystem comprises on-board host OBS and on-board peripheral equipment, and the on-board peripheral equipment is connected to the on-board equipment external interfaces by means of the on-board host OBS,
• wherein the on-board host OBS comprises an ATP master control unit and a speed and distance measurement unit, a balise information receiving unit, a train integrity receiving unit, a data recording unit, a train interface unit, a wireless transmission unit and a satellite receiving unit which are respectively connected to the ATP master control unit;
• and the on-board host OBS determines the speed and the position by combining satellite information, a balise and a speed sensor to measure the speed and the distance,
• wherein the system realizes the train-ground wireless communication and wireless communication between the on-board host OBS and train tail equipment in the low-density freight railways by means of a DMR digital co-frequency relay technology, and digital signals are received and synchronously forwarded via a DMR co-frequency relay base station to ensure timely communication and to reduce delay.
