System and method for controlling passage of autonomous rail rapid transit in virtual turnout area

Abstract

The invention relates to the field of rail transit, in particular to a system and a method for controlling the passage of autonomous rail rapid transit in a virtual turnout area. The system for controlling the passage of autonomous rail rapid transit in the virtual turnout area comprises: a vehicle-mounted device, which is in wireless communication with a ground device, sending a virtual access application command when the vehicle-mounted device is close to the virtual turnout area, receiving a passing permission or passing forbidding signal from the ground device, and deciding whether to drive into the virtual turnout area or not; and the ground device, which is used for carrying out interlocking control logic judgment according to the access application signal in combination with the relative position information of the vehicle-mounted device, and feeding back a passage permission signal or a passage forbidding signal to the vehicle-mounted device, wherein the virtual turnout area isa wireless coverage area formed by ground device. Based on the ultra-wideband (UWB) positioning technology, the accurate position of the autonomous rail rapid transit in the virtual turnout area is calculated in real time, protection control over the vehicle in the virtual turnout area is completed through ground interlocking, and safe operation of the autonomous rail rapid transit in the virtualturnout area is achieved.

Description

technical field [0001] The invention relates to the field of rail transit, and more specifically, to a system and method for controlling the passage of smart rail cars in virtual fork areas. Background technique [0002] As the problem of urban traffic congestion becomes increasingly prominent, a variety of public transportation solutions have been proposed, including subways, BRT (Bus Rapid Transit), light rail, smart rail, etc. Among them, the smart rail express system with smart rail cars as the core vehicle has the advantages of short construction period, small infrastructure investment, high urban adaptability, and strong comprehensive transportation capacity, and has a good application prospect. [0003] Intelligent rail cars adopt high-speed rail flexible marshalling, use "virtual track following control" technology to run on the established "virtual track", have the characteristics of zero emission and no pollution of rail trains such as light rail and subway, and su...

AI Technical Summary

Problems solved by technology

[0006] 1) The position of the vehicle detected by the beacon is a discrete position, and the running direction and position of the vehicle are not judged. Multiple sets of beacon reading equipment need to be installed in a branch area, and the construction difficulty of the main line and the vehicle base increases;

[0007] 2) Without considering the impact of hostile routes and the failure of key equipment, the control method based on the unified dispatch of the center is adopted, which is not very practical
