Movable blocking downgrading operation system and method

Abstract

The invention relates to the technical field of railway signals and discloses a movable blocking downgrading operation system and method. According to the system, a plurality of axle counters are arranged on arrival signal machines and a plurality of pass signal machines of two adjacent stations correspondingly, wherein the multiple pass signal machines are arranged in the interval formed by the arrival signal machines to divide the interval into a plurality of sections, and the axle counters detect whether each section is idle or not; according to the detecting results of the axle counters of the corresponding sections, the pass signal machines display indicating signals; a plurality of railway circuits are arranged in the preset range travelled when a train arrives at the pass signal machines, and train control codes are sent according to the indicating signals displayed by the corresponding pass signal machines; and train-mounted equipment receives the train control codes and controls the train to operate according to the train control codes. The movable blocking downgrading operation system and method are mainly applied to the movable blocking failure condition, thus under the condition, the operation safety of the train can still be ensured, and the train has the certain transporting efficiency and capacity; and meanwhile the engineering cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of railway signals, in particular to a mobile block degraded operation system and a mobile block degraded operation method. Background technique [0002] In the field of railway signaling, blocking means that after a train enters a section, it is isolated from the outside world, and stations at both ends of the section no longer depart to this section to prevent trains from colliding and rear-end collisions. This was the concept of early single-track railways, now known as semi-automatic blockades. With the development of technology, railways need to increase their transportation capacity, especially after the development of single-track railways into double-track railways, the concept of automatic blockage appears, that is, the interval between two stations is divided into several block sections, and only one block is allowed in each block section. The train runs. Blocking equipment is the railway...

Problems solved by technology

[0005] However, after the failure of the key equipment of the mobile block, if it is downgraded to an automatic block between stations, only one train is allowed to run between two adjacent stations, which has a great impact on the transportation capacity
