Embodiment 1

[0043] refer to figure 1 , the CBTC and regional interlocking integrated system includes a vehicle-vehicle communication integration device 10 and a vehicle-ground communication integration device 20;

[0044] Wherein, in the case of automatic mode control, the vehicle-vehicle communication integrated device 10 is used to obtain the first position information, route application information and first route data information, and process the first position information and route application information , to obtain the first route state information, and then calculate the first movement authorization restriction LMA (Limit Movement Authority, movement authorization restriction) information according to the first line data information and the first route state information;

[0045] In the case of backup mode and manual mode control, the vehicle-ground communication integration device 20 is used to obtain the second location information and the second line data information, and calcu...

Embodiment 2

[0078] refer to Figure 4 , the integration method of CBTC and regional interlocking includes the following steps:

[0079] Step S101, identifying the signal, and judging the control mode according to the signal;

[0080] Step S102, when the control mode is the automatic mode, obtain the first location information, route application information and first route data information, process the first position information and route application information, and obtain the first route status information, according to The first line data information and the first route state information calculate the first mobile authorization restriction LMA information;

[0081] Specifically, during normal operation, the signal system is mainly based on the automatic driving mode of vehicle-to-vehicle communication, the vehicle-mounted VOBC calculates the LMA by itself, and realizes mobile blocking, and the train control adopts a continuous control method. The automatic mode is the automatic drivin...

Abstract

The invention provides a CBTC (Communication Based Train Control) and regional interlocking integrated system and method, relating to the technical field of rail transit. The system comprises a train-train communication integrated device and a train-ground communication integrated device; in case of control with an automatic mode, the train-train communication integrated device acquires first location information, route entering application information and first line data information, processes the first location information and the route entering application information to obtain first route entering state information, and calculates first LMA (Limit Movement Authority) information according to the first line data information and the first route entering state information; in case of control with a backup mode and a manual mode, the train-ground communication integrated device acquires second location information and second line data information, and calculates second LMA information according to the second locationinformation and the second line data information, thus optimizing closed-loop control links, ensuring stability of the integrated system and improving rail transit operating efficiency.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an integrated system and method of CBTC and regional interlocking. Background technique [0002] With the development of urban rail transit, CBTC (Communication Based Train Control, communication-based train operation control system) technology and interlocking technology of signaling system have been widely used in high-density train safety automatic control. Although the interface between CBTC and the interlocking ground control part facilitates the coordinated control of trackside equipment, as the maturity of CBTC applications continues to increase, the exposed equipment settings, overlapping functions, transmission delays and faults in the interface links also affect It affects the reliability and safety of the signal system, and restricts the further improvement of the operating efficiency of the entire rail transit. Contents of the invention [0003] In view of thi...
