摘要

计算机联锁软件的基础是联锁软件数据结构的选取和进路搜索算法的设计。针对传统计算机联锁系统上位机软件在站场结构发生变化时需要作出大量修改的问题，为提高联锁系统的灵活性与可重用性，降低人员劳动强度，一方面通过拖拽的方式由控件拼凑构建平面站场图，达到平面站场图灵活重构的目的；另一方面，利用二叉树与站场数据结构之间的相似性建立单链表站场数据结构。在此基础上，提出了一种新的计算机联锁进路搜索算法，达到使整个计算机联锁系统上位机软件可重用的目标。整个计算机联锁上位机软件以VS2015为开发平台，采用面向对象的语言进行编写与实现，为车站的后期改造提供便捷。

Abstract

The basis of computer interlocking software is the selection of data structure of interlocking software and the design of path searching algorithm. The software of the traditional computer interlocking system needs to make a lot of modifications when the structure of the station changes. In order to improve the flexibility and reusability of the interlocking system and reduce labor force, on one hand, the planar station map was constructed by dragging and pulling controls to achieve the purpose of flexible reconstruction of the planar station map; on the other hand, the data structure of single-linked list was established by using the similarity between binary tree and station data structure. On this basis, a new computer interlocking route search algorithm was proposed by using recursive algorithm to achieve the goal of reusing the upper computer software of the whole computer interlocking system. The whole computer interlocking upper computer software was written and implemented in object-oriented language on VS2015 development platform,which provided convenience for the late reformation of the station.
