Intelligent transport system for urban railway based on safety communication

Abstract

The invention discloses an intelligent transport system for an urban railway based on safety communication. The intelligent transport system for the urban railway comprises a DCS (data communication system), an ATS (automatic train supervision), an ATP (automatic train protection), an ATO (automatic train operation), a DTO (driverless train operation) and a MMS (maintenance management system), wherein the ATS, the ATP, the ATO, the DTO and the MMS realize the network connection through the DCS. The intelligent transport system for the urban railway has the advantages that the proper Internet storm influence of a CBTC (communication based train control) is favorably overcome, the safety problem of the train-ground wireless communication is favorably solved, the man-machine interface of the CBTC is favorably unified, the linkage efficiency among the systems under the emergency condition is improved, the ease maintenance of the system is enhanced, and the complete network operation scheme is provided.

Description

technical field [0001] The present invention relates to an Intelligent Transport System for Urban Railway (ITS-UR for short) based on safe communication. rail transit needs. The invention belongs to the technical field of intelligent traffic safety control. Background technique [0002] In recent years, "communication-based train control system (CBTC)" has been widely adopted as the main system in the field of urban rail transit intelligent control system in domestic urban rail transit construction and renovation projects. The CBTC system has two standards: CBTC using inter-rail cables as the transmission channel (called IL CBTC) and CBTC using wireless data transmission communication (called RF CBTC). In view of the fact that the cable of IL CBTC is easy to be stolen, it is not conducive to the line Maintenance, so RF CBTC has become the main CBTC standard. Although the RF CBTC system has already had successful cases in China, it can realize mobile blocking, improve the ...

AI Technical Summary

Problems solved by technology

[0003] 1) The mobile block system is adopted, which increases the communication volume between the train and ground equipment, which is likely to cause an impact on the backbone network and form a sudden "network storm", which will cause communication delays between the control center equipment, trackside equipment, and on-board equipment. interruption;

[0004] 2) The vehicle-to-ground wireless communication adopts the IEEE standard protocol, which increases the risk of external intrusion into the system;
