Anti-locking control method for turn-back region running of rail intersecting train

Abstract

The invention discloses an anti-locking control method for turn-back region running of a rail intersecting train. The method includes the steps that a rail access transaction region and a turn-back region are arranged; the train checks whether the rail access transaction region is locked or not, if the rail access transaction region is locked, the train waits for the rail access transaction region to be unlocked in front of the rail access transaction region, and if the rail access transaction region is not locked, the train enters the rail access transaction region; the train reaches the rail access transaction region and checks whether the turn-back region is occupied by another train or not, if the turn-back region is occupied by another train, rail access is not transacted, and the train waits in the rail access transaction region; if the turn-back region is not occupied by another train, the train obtains the use right of the turn-back region, rail access is transacted, and the train enters the turn-back region; the train reaches a turn-back point, and the rail access transaction region is unlocked; and after the train leaves the turn-back region, the turn-back region occupation right is released. By the adoption of the method, the train can be accurately controlled and dispatched, the train efficiently passes through the turn-back region in order, and the situation that the train is locked in the turn-back region is avoided.

Description

technical field [0001] The invention relates to the field of automation control, in particular to an anti-locking control method for rail transit trains running in a turning area. Background technique [0002] With the continuous improvement of my country's urbanization level, the pressure on urban traffic is increasing, and rail transit plays an important role in the urban traffic system. However, the huge cost and long construction period of the light rail subway limit its development in small and medium-sized cities. Faced with the current urgent transportation needs, modern trams with low cost and short construction period have been recognized by the city as a transportation mode with less energy consumption per unit, no pollution, and medium transportation capacity. The revival of modern trams in Europe also reflects the excellent ability of trams to relieve urban traffic pressure. Modern trams have the characteristics of reliable operation, comfort, energy saving, an...

Problems solved by technology

like figure 1 As shown, in the absence of an anti-locking control method, platform A to platform B is a section of the running line; when train 1 arrives at platform B, the route is unlocked, and train 1 stops at platform B; train 2 goes to platform B approach; such as figure 2 As shown, train 1 and train 2 are running towards each other, and a deadlock occurs. Train 1 and train 2 cannot continue to operate according to the planned route, and subsequent vehicles cannot pass through this area, resulting in the suspension of the entire line operation.
