Abstract

The invention provides a train operation control system, a method and a device. In the train operation control system, at least two vehicle-mounted radio control units are connected with one another, and the vehicle-mounted radio control units are connected with ground traction control equipment and different positioning equipment; the vehicle-mounted radio control unit is used for acquiring the positioning information acquired by the connected positioning equipment, sending the acquired positioning information to other vehicle-mounted radio control units connected with the vehicle-mounted radio control unit, receiving the positioning information sent by other vehicle-mounted radio control units, and sending all the obtained positioning information to ground traction control equipment. According to the train operation control system, the method and the device provided by the embodiment of the invention, the transmission redundancy of the positioning information is greatly increased, and the situation that the positioning information is not transmitted to the ground traction control equipment is avoided as far as possible.

Description

technical field [0001] The invention relates to the field of maglev technology, in particular to a train operation control system, method and device. Background technique [0002] At present, after the maglev train obtains the positioning information through the maglev train positioning system, it can send the obtained positioning information to the ground base station through the wireless communication system. [0003] The high speed of the maglev train makes the mobile communication network between the maglev train and the ground base station unstable, and it is easy to cause the positioning information not transmitted to the ground base station when the maglev train transmits the positioning information to the ground base station. Contents of the invention [0004] In order to solve the above problems, the purpose of the embodiments of the present invention is to provide a train operation control system, method and device. [0005] In a first aspect, an embodiment of t...
