本项目是市建委下达的科研课题,由市地方铁路局技术处和铁道部信号研究设计院共同承担。在1993年5月27日通过了由市建委组织的鉴定。经过北大港车站1年来的经营,证明工作稳定、安全可靠,在不远的将来,微机联锁将逐步取代目前的6502电气集中控制。本文对该系统的硬件和软件这两大部分作了阐述,并着重指出其安全措施和特点。具体内容为:(1)本系统的构成。硬件有联锁计算机、高分辨率彩色监视器、微型化集中操纵台、安全型继电器输入输出接口柜、微机联锁专用电源以及信号机。软件有车站数据库和应用程序(系统管理程序、时钟中断管理程序、信息采集及处理程序、操作命令输入及分析程序、选路及转岔程序、信号开放程序、解锁程序、站场彩色显示程序)。(2)本系统的安全措施。(3)本系统的特点。
This project is issued by the Municipal Construction Commission of scientific research topics, by the city Department of Railway Technology and the Ministry of Railways signal research and Design Institute shared. On May 27, 1993, it passed the appraisal organized by the Urban Construction Commission. After a year of operation at Beidagan Station, it proves that the work is stable, safe and reliable. In the near future, the microcomputer interlock will gradually replace the current 6502 electric centralized control. In this paper, the hardware and software of the system are described in two parts, and highlight its security measures and features. The specific content is: (1) The composition of the system. Hardware interlock computer, high-resolution color monitor, miniaturized centralized console, safety relay input and output interface cabinet, microcomputer interlocking power supply and signal. The software has station database and application programs (system management program, clock interrupt management program, information acquisition and processing program, operation command input and analysis program, routing and switching program, signal open program, unlock program, station color display program) . (2) the system’s safety measures. (3) The characteristics of the system.
