A Train Operation Control System Based on Space-Sky-Train-Ground Integrated Network

Abstract

The invention discloses a train operation control system based on a space-air-vehicle-ground integration network. The train operation control system comprises an aircraft, a satellite, a wireless communication base station, vehicle-mounted equipment, trackside equipment and a dispatching center, wherein the aircraft is used for achieving train speed measurement, train location, line or turnout condition monitoring and a communication function; the satellite is used for achieving train speed measurement, train location and a communication function; the wireless communication base station is used for achieving a communication function; the vehicle-mounted equipment is used for achieving train speed measurement and train location, train control and a communication function; the trackside equipment is used for achieving train speed measurement, train location, line or turnout condition monitoring and turnout control; the dispatching center is used for achieving line or turnout resource dispatch and trackside equipment control. By means of the space-air-vehicle-ground integration network, dynamic adjustment of transport capacity of low-transport-capacity rails is achieved, and the requirement for high transport capacity in a special period is met. In addition, the train operation control system can operate according to an ordinary train operation control system in a normal period, the cost is reduced, and the train safety is guaranteed through redundancy design.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and relates to a train operation control system for rail transportation, in particular to a train operation control system based on an integrated network of space, sky, vehicle and ground. Background technique [0002] At present, the train control systems that support high-density, high-capacity operation are all communication-based mobile block systems. At present, the vehicle-ground communication mode of the communication-based mobile block system is generally one of GSM-R, WLAN, and LTE, and these communication modes are all based on the trackside AP. [0003] For low-capacity railways, the long-term demand for transport capacity is low, and there are few trains usually running. If the existing communication-based mobile block system is used, the cost of deploying trackside APs is high, and the cost performance is not high, because it is hardly used in normal times, and it relies ...
