Abstract

The invention relates to the technical field of train safety operation control, and discloses a train control system based on satellite communication and public cellular communication. The train control system comprises train-mounted equipment and ground equipment. The train-mounted equipment comprises a wireless communication unit. The ground equipment comprises a communication interface server. The wireless communication unit is used for conducting information transmission between satellite communication and public cellular communication networks and the communication interface server. The communication interface server is used for receiving position reports transmitted by the wireless communication unit and transmitting traveling permits and temporary speed limitation information generated by the ground equipment to the wireless communication unit. By the adoption of the train control system based on satellite communication and public cellular communication, stable, reliable and continuous mutual communication between the train-mounted equipment and the ground equipment is achieved through the combination of satellite communication and public cellular communication, the construction cost of train and ground wireless communication networks is greatly reduced, and automatic control over train operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of train safety operation control, and in particular relates to a train safety operation control system which utilizes satellite communication and public cellular communication to transmit train-ground information. Background technique [0002] The train control system uses positioning, communication and other related technologies to control the train's running direction, running interval and running speed, so that the train can run safely and efficiently. The blocking control equipment and station interlocking equipment of the train control system mainly realize the route control and tracking interval control, and generate the driving permit, and then transmit the driving permit to the train through the train-ground wireless transmission channel. After receiving the driving permit, the on-board equipment generates Train speed control curve, supervising and controlling the safe and efficient operation of tra...
