恰希玛核电站全范围仿真控制室实时网络和接口系统的设计

Real-The Network and I/O Interface of Full Scope Simulator for Chashma 300MW Nuclear Power Plant

介绍了在巴基斯坦恰希玛300MW核电站全范围仿真控制室中使用的实时网络和接口系统的设计思路和最终性能。该网络系统采用了10BASE5以太网技术和EDC公司的PATHWORK for DOS(TCP/IP)网络环境。接口系统由工业PC机、CRTP实时工业总线以及智能化RS232接口组成分布式处理系统,对约14000路数据(其中模拟量2500点,数字量达12000点以上)I/O实时刷新,仿真周期可达每秒12次以上,通讯耗时每次约14ms。

This paper introduced the real-time network and I/O interface, design consideration and features offull scope simulator for pakistan Chashma 300MW nuclear power plant. The network used 10 BASE5 Ethernettechnology and under the PATHWOHK for DOS(TCP/IP) network environment. I/O interface consisted of indus-try PC, CETP products and intelligent RS232 interface and distributed process about 14000 channel(analog 2500,digital above 12000). The simulation frequency is 12 per second, communication time is about 12 ms.
