Interface method of EMU depot (office) control centralized system and signal system

Abstract

The invention provides an interface method of an EMU depot (office) control centralized system and a signal system. The method includes the steps of S1, expanding the functions of the EMU depot (office) control centralized system (CCS) to allow the CCS to have all the functions of centralized traffic control (CTC) extension equipment in the signal system, and omitting the CTC extension equipment;S2, transforming the information flow of the CCS and the signal system to allow the a train operation plane issued by CTC central equipment to be directly transmitted to interlocking equipment throughthe CCS; S3, modifying the interface position and interface manner of the CCS and the signal system to build connection between the CCS and the CTC central equipment and the connection between the interlocking equipment and a train control center (TCC). By the method, the data transmission flow of train operation plan issuing and execution is simplified, risks generated by the simultaneous operation of the CTC extension equipment and the CCS equipment, equipment idleness is reduced, and the equipment work efficiency of an EMU depot (office) is increased.

Description

technical field [0001] The invention relates to the field of railway signal system interface design, in particular to an interface method between a centralized control system and a signal system of a bullet train depot. Background technique [0002] Traditionally, the high-speed rail signaling system mainly includes centralized dispatching (CTC), interlocking, blocking, train control, and centralized monitoring subsystems. The new centralized control system (CCS) in the bullet train depot completes the automatic control functions related to the signal system, such as the acquisition of train plans and the issuance of train route control commands, through the interface with the signal system. [0003] Among them, for CTC: high-speed railways, including passenger dedicated lines and intercity railways, are generally equipped with centralized dispatching (CTC) systems. It is a kind of railway signal technology equipment that commands and manages trains and shunting operations ...

AI Technical Summary

Problems solved by technology

This processing method increases the workload of the CTC system and increases the coupling between the CTC and CCS systems, which is not conducive to the modular design of the system; there is no clear demarcation between the working modes of CTC "decentralized self-discipline" and CCS "centralized control". Determined by the management system

[0012] (2) CTC and CCS system control terminals have not realized mutual card

[0013] From the technical requirements of CTC and CCS, both CTC and CCS switch the control mode through the interlocking system to distinguish whether the system is in the "very station control" mode. CTC and CCS have not realized the switching and interlocking of different control modes. Both CTC and CCS system equipment can be used when it is not in the "very station control" mode. Improper use will cause failure or error to the system

[0014] (3) The control terminal of CTC is idle

On the one hand, repeated investment in equipment is not conducive to the full utilization of resources; on the other hand, the normal operation of the CCS system depends on the guarantee of the equipment management system

[0016] (4) The implementation of the train operation plan increases

This type of information transfer method increases the complexity of information processing in the CTC system, which is not conducive to the stability of the system

[0018] (5) Application risks brought about by limited information interaction between the two systems

[0019] When CCS is in use, the CTC station extension runs in parallel with it, but according to the technical conditions of CCS, the content of the information exchanged between the two is limited, for example, there is no interaction between CCS and CTC. Therefore, if one of the two systems needs to switch the control right due to a certain system, the information of the two systems is not synchronized, which will cause confusion in the operation of the operators
