Problems solved by technology

Under the traditional fixed block system, the system cannot know the specific position of the train in the zone, so the starting point and end point of the train braking are always at the boundary of a certain zone

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1-3 shown.

[0022] A kind of train location method applicable to different blocking systems, it comprises the following steps:

[0023] First, input the entire route of the train in the form of a digital map into the calculation computer located in the control center and the route computer installed in the station; all target points related to driving are corresponding to a description point in the digital map.

[0024] Secondly, use the start and end points of the existing track circuit or beacons as the description points of the physical block partition, and then use mobile communication technology to divide each two description points into several virtual block partitions during the train operation process;

[0025] Third, the on-board equipment automatically and regularly notifies the absolute position coordinates of the tr...

Abstract

Aiming at the existing mainstream blocking systems in the automatic control system of urban rail transit trains, the present invention discloses a train positioning method compatible with fixed blocking (including quasi-moving blocking) and moving blocking and suitable for different blocking systems. It is not only suitable for train positioning under fixed block conditions, but also suitable for train positioning under moving block conditions, and finds a good solution for the transition from fixed block system to mobile block system.

Description

technical field [0001] The invention relates to a method for realizing train positioning, in particular to a method for realizing train positioning compatible with fixed blocking, quasi-moving blocking and moving blocking in an urban rail transit control system, specifically a method suitable for different blocking systems Train location method. Background technique [0002] In rail transit, in order to ensure the safety of train operation, it is necessary to ensure that the trains run at a certain safety interval, which is what the signal professional calls the block partition. [0003] In the early days, people used the signal system of fixed block (including quasi-movable block) to ensure the safe operation of trains. That is to say, the line is fixedly divided into several block zones, and the size of each block zone is determined according to the braking length of the train with the worst performance. Each blocked area is equipped with a corresponding position detecti...
