Temporary speed limiting method and temporary speed limiting system in urban rail transit CBTC (communication based train control system) mode

Abstract

The invention discloses a temporary speed limiting method in an urban rail transit CBTC (communication based train control system) mode. The temporary speed limiting method includes starting normal route control after uploading and confirming temporary speed-limiting information before power interruption through a data storage unit, uploading the temporary speed-limiting information periodically to an automatic monitoring system from the data storage unit, performing interactive confirming twice between the data storage unit and the automatic monitoring system, dividing the temporary speed-limiting information and then downloading the same through the data storage unit, receiving the temporary speed-limiting information and feeding the information back to the data storage unit and then downloading movement authority speed-limiting instructions by zone controllers, saving feedback results by the data storage unit, and performing speed-limiting brake to trains through an automatic protection system. With the temporary speed limiting devices in the urban rail transit CBTC mode, the defect that effective speed limiting can be carried out by completely depending on real-time communications between dispatchers and drivers in the conventional speed limiting measures is overcome, the safety coefficient is increased, and running safety is guaranteed. The invention further discloses a temporary speed limiting system.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a temporary speed limiting method and a speed limiting system in urban rail CBTC (Communication Based Train Control System, communication-based train operation control system) mode. Background technique [0002] In urban rail transit, subways are generally divided into ground lines, ground lines and underground lines. Comprehensive consideration, the ground line will be the first choice. In addition, subways are generally built in areas with a large population flow and dense commerce and communities. Moreover, the operating hours of the subway are basically between 5:30 in the morning and 23:30 in the evening. Therefore, whether it is a subway under construction or in operation, it is directly related to people's lives and the urban environment. [0003] In the process of subway operation, infrastructure failures will inevitably occur. In order to avoid the paralysis ...

Problems solved by technology

[0004] In the prior art, when a train needs to run at a low speed temporarily, the speed can only be controlled by manual means, that is, the on-duty dispatcher talks to the driver. Sections are controlled in the form of intervals, which reduces operational efficiency and low troubleshooting efficiency, and there are certain security risks in relying on human operations
