Problems solved by technology

However, if the forward and reverse directions are considered at the same time when calculating the effective time of the backup variable, since the reverse approach is generally relatively long, it will inevitably cause the effective time of the backup variable to be too long, which will affect the operational efficiency.

Embodiment

[0033] Add reverse point backup active beacons at appropriate locations, so that when the train is running in reverse, it will not cause emergency braking due to the failure to update the effective time of the backup variable in time. The configuration diagram is as follows figure 1 , figure 2 , image 3 shown. Backup variable valid time T=Max([distance A / (forward point-type average inter-station speed)]; [(Max (distance B; distance C) / (forward point-type average inter-station speed))+( longest platform length / (average speed of forward platform)+(maximum stop time)]

[0034] Among them, the distance A = the longest distance from the active beacon corresponding to the outbound signal or the interval signal of the long interval to the third consecutive active beacon;

[0035] Distance B = the longest distance from the previous active beacon of the last interval signal in the long interval to the entrance of the next station except the signal of the next station;

[0036] D...

Abstract

The invention relates to a method for setting a reverse dot type active beacon, so that a protection demand of a reverse dot type ATP system can be satisfied. The method comprises: according to forward equipment arrangement, forward dot type reserve variable effective time T is calculated; traction simulation calculation is carried out to obtain a reverse inter-station operation time t of a train; on the basis of a relationship between the reserve variable effective time T and the reverse inter-station operation time t of the train, a corresponding station position needing to add a reverse active beacon is determined; and after completion of the above-mentioned steps, whether a distance between the newly-added active beacon and a concentrator station which the newly-added active beacon belongs to exceeds a set distance is determined; and if so, a corresponding annunciator is added and the concentrator station which the active beacon belongs to is changed. Compared with the prior art, the method has the following advantages: hardware equipment can be saved; the operation, maintenance, and debugging work efficiency is improved; and reversed dot type ATP protection is provided on the premise that the forward dot type ATP operation efficiency is not affected.

Description

technical field [0001] The invention relates to the technical field of rail transit safety driving, in particular to a method for setting a reverse point active beacon. Background technique [0002] In order to meet the needs of people's travel, the operation time of subway lines has been continuously extended, and the time left for subway operation and maintenance and project debugging has become shorter and shorter. In order to improve efficiency and ensure safety, it is necessary for trains to run in reverse and provide ATP protection. However, if the forward and reverse directions are considered at the same time when calculating the effective time of the backup variable, since the reverse approach is generally relatively long, it will inevitably cause the effective time of the backup variable to be too long, which will affect the operational efficiency. Contents of the invention [0003] The object of the present invention is to provide a method for setting a reverse ...
