Operation sequence selecting method suitable for STP operation test

Abstract

The invention discloses an operation sequence selecting method suitable for an STP operation test. The operation sequence selecting method suitable for the STP operation test comprises the steps of abstracting a whole railway yard into binary tree representations of different tree roots according to throats by using station tracks as boundaries, yard edge segments as root nodes, station tracks asleaf nodes and equipment on a path as other nodes of a binary tree; carrying out depth-first search on each tree and intensively marking passing segments; and after all searches are finished, using marked information to calculate an occupation error and a clearance error of each segment. According to the operation sequence selecting method suitable for the STP operation test, through tree form modeling, depth-first search and undetected segment statistics, the coverage of operation segments is guaranteed, and the omission probability of completely depending on manually following a vehicle to review the lengths of segments is effectively reduced. Through statistics of operation conditions and results of different segments, statistical analysis of the segment length error is automatically output so that the working intensity of manually following and watching the vehicle is effectively reduced, and the statistical accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for selecting an operation sequence suitable for an STP operation test. Background technique [0002] With the widespread use of wireless shunting locomotive signal and monitoring system (STP) in the whole road, the safety protection of special shunting locomotive operation process has been effectively guaranteed. STP adopts the "target-distance" mode to control the train to stop within a safe distance before the signal is closed in front. Through the real-time tracking of the position of the train, the real-time calculation of the distance from the front end of the train to the parking point is realized. Therefore, the distance is important for system control. It plays a decisive factor. If the distance error is large, the protection function of the system cannot be discussed at all. In accordance with the requirements of the "Administrative Measures for the Opera...

AI Technical Summary

Problems solved by technology

The current methods are mainly based on the normal operation of the shunting operation, which is completed by manual follow-up and monitoring, which has the characteristics of long time, strong subjectivity, and high intensity of monitoring and control. Based on experience and manual compilation of train reception and departure conditions at stations, there is no effective technical means to automatically compile the pressure track plan
