Embodiment

[0092] Utilize described train priority calculation method and each equipment function logic below, with Figure 4 The train concurrency situation shown is taken as an example for modeling and analysis. Assume that the starting positions of train 1 and train 2 are on the throat tracks on both sides of the station. First, calculate the static priority of the train. Because the importance of the track is the same, it is assumed that Z1=Z2=2; since both train 1 and train 2 are entering the station, it is assumed that train 1 is more urgent than train 2, so A1=4, A2=1; the types are the same S1=S2= 1. The weight values ​​are w1=0.2, w2=w3=0.4. Therefore, before entering the station, the static priority of train 1 and train 2 is determined locally, which are respectively:

[0093] ps1=0.2*2+0.4*4+0.4*1=2.4 (3)

[0094] Ps2=0.2*2+0.4*1+0.4*1=1.2 (4)

[0095] Secondly, when the two trains both send the application for entering the station to the signal machine, the signal machine...

Abstract

The invention discloses a distributed train concurrent dispatching method based on train priorities, which comprises signal machine dispatching, switch machine dispatching and track circuit dispatching. By correlating trains with priorities, the distributed train concurrent dispatching method based on the train priorities solves the concurrent conflict of a system. The method for determining the priorities views track sections and the like occupied and obtained by the trains during running as limited resources and therefore the trains are endowed with different static priorities according to the importance of the resources owned by the trains in a line and in combination with requirements on real time. In combination with dynamic properties, dynamic priorities are determined by comprehensively considering relevant factors according to a running plan to realize the dynamic allocation of the resources and the concurrent running of the trains.

Description

technical field [0001] The invention belongs to the technical field of train scheduling and control, and relates to a train scheduling method, in particular to a distributed train concurrent scheduling method based on train priority. Background technique [0002] Due to its advantages of large volume, low price and relative safety, railway has gradually become the preferred mode of transportation for people in recent years. Therefore, on the premise of ensuring the safety of train operation, how to improve the speed and efficiency of trains has become a research hotspot. As a key system to ensure the safe operation of trains in the station, the station interlocking system has always been the focus of researchers. Since computer technology was introduced into the railway interlocking system 30 years ago, it has played a huge role in ensuring the safe operation of trains. The fully decentralized railway interlocking system emphasizes the dispersion of equipment in physical l...
