Automatic interstation blocking control method and system under heavy-load movable blocking

Abstract

The invention provides an automatic interstation blocking control method and system under heavy-load movable blocking. The method includes: arranging an axle counter between a first state and a secondstation; determining interstation state between the first station and the second station according to interstation occupation condition between the first station and the second station and collectedby the axle counter by interlocking equipment of the first station or that of the second station; when the first station applies an outgoing route to the second station, determining interstation statebetween the first station and the second station by the interlocking equipment of the first station and that of the second station by means of mutual communication, and performing control managementon interstation blocking between the first station and the second station according to the interstation state between the two. By the method, the characteristic that mutual communication can be realized during interlocking under movable blocking is utilized fully, the axle counter is arranged to collect the interstation occupation condition on the basis of interlocking communication, automatic interstation blocking is realized, and running efficiency after heavy-load movable blocking degradation is improved effectively.

Description

technical field [0001] The invention relates to the technical field of safety control, in particular to an automatic inter-station block control method and system under heavy-duty mobile block. Background technique [0002] The degraded operation scheme of the existing heavy-haul railway system adopts the traditional inter-station block. There can only be one train running at the same time between the departure signal of this station and the arrival signal of the next station under blockage between stations. For inter-station block safety control, the most commonly used is semi-automatic inter-station block, such as figure 2 The Model 64D relay shown is a semi-automatic blocker. see figure 2 , set up a pair of semi-automatic blocking machines (BB) at two adjacent stations in a section, and connect them through the blocking telephone line between the two stations, and through the mutual control of the semi-automatic blocking machines at two stations, it is ensured that onl...

AI Technical Summary

Problems solved by technology

[0004] The main problem of semi-automatic blocking is that there is no idle inspection equipment in the section, and the complete arrival of the train must be confirmed manually. In case of ...
