Research on Software Design Optimization of Temporary Speed Restriction Server
摘要
Abstract
Temporary Speed Restriction Server (TSRS) to achieve centralized management of Temporary Speed Restriction (TSR) is the basic equipment of CTCS-2/3 level train control system.This paper analyzes the TSR state and the transformational relation of the interaction between TSRS and the external equipment and four TSRS software optimization measures are put forward.Cancellation of TSR life cycle optimization design can optimize the TSR cancellation process.Increasing collision validation in proposing phase can solve TSR proposing error.Suspending refresh between TSRS in validation and implementation phase can solve the occasional failure during verification or implementation of TSR.Based on balanced binary search tree of TSR management, algorithms to meet the requirements of the size of a balanced binary tree (SBT), AVL trees and red black tree (RBT) are proposed, the efficiencies of randomly insert and delete of a plurality of TSR of the three algorithms are tested to find out suitable TSRS temporary speed restriction management algorithm, which can provide decision-making basis for the optimization design of TSRS software.关键词
