Method and system for temporary speed limitation in urban rail transit

Abstract

The invention provides a method for temporary speed limitation in urban rail transit. The method comprises the following steps: after an ATS (Automatic Train Supervision) workstation sets up the temporary speed limitation, a DSU (Data Service Unit) carries out legality check on the temporary speed limitation as well as carries out correctness check on the temporary speed limitation together with the ATS workstation; after the correctness check is passed, the DSU sends out the temporary speed limitation to a ground ATP (Automatic Train Protection) system; the ground ATP system respectively sends the temporary speed limitation to a vehicle-mounted ATP system and a computer interlocking system, so that the vehicle-mounted ATP system executes CBTC (Communications Based Train Control) temporary speed limitation, and the computer interlocking system executes point type temporary speed limitation. The invention also provides a system for the temporary speed limitation in the urban rail transit. The system comprises the ATS workstation, the DSU, the ground ATP system, the vehicle-mounted ATP system and the computer interlocking system. According to the method and the system, the setup, the management, the issuing and the execution of the temporary speed limitation are realized by using typical signal equipment, and the CBTC temporary speed limitation and the point type temporary speed limitation are integrated.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and system for temporary speed limit of urban rail transit. Background technique [0002] Temporary speed limit is an important measure to ensure the safety of train operation during the train running process. In the actual operation process, due to construction, maintenance and other reasons, the temporary speed limit control of the train is often carried out as needed. If the train speeds in the speed limit area Driving may cause serious accidents such as derailment. Therefore, it is very important to ensure the correctness and reliability of the temporary speed limit. The urban rail transit signal system is different from the railway / high-speed rail signal system. There is no unified standard or specification for temporary speed limits. The products of each signal system supplier are different, and the operational needs of each city are also different. [...

AI Technical Summary

Problems solved by technology

[0004] Under the point-type control level, the train receives mobile authorization information through the ground active transponder, and the communication between the ground and the train is discontinuous. At present, there is no mature point-type temporary speed limit method and system, and a set of point-type temporary speed limit equipment needs to be configured separately
