定制工控机在老旧线路计算机联锁设备中的应用

Application of Customized Industrial Computer in Computer Interlocking Equipment in Existing Railway

计算机联锁是铁路车站信号系统的核心设备,《维规》规定,二乘二取二计算机联锁设备使用寿命为15年,联锁系统中的工控机使用寿命为10年,因此在1个计算机联锁设备的寿命周期内一定存在1次工控机局部大修。本文结合1条既有线联锁工控机局部大修过程中遇到的诸多问题,对工控机与板卡兼容性、资源占用、功耗、对外接口等问题进行分析并提出解决方案,为联锁工控机进行大修时的工控机选型和施工提供借鉴。

Computer Interlocking is the core equipment of station signal.The Regulation on Railway Signal Maintenance stipulates that the service life of the computer interlocking equipment is 15 years and the service life of the industrial control computer in the interlocking system is 10 years.So,there must be a local overhaul of the industrial control computer in the life cycle of computer interlocking equipment.In combination with the problems encountered in the local overhaul of the industrial control computer in an existing line,the compatibility between IPC and board,resource occupation,power consumption,external interface and other issues are described and the solutions are put forw ard,which can be used for reference in the selection and construction of IPC in an overhaul of the interlocking IPC.
