大亚湾核电站全范围模拟机硬件 I/O 实现

The Full Scope Simulator Hardware I/O Realization in Daya Bay Nuclear Power Station

广东大亚湾核电站全范围模拟机(以下简称模拟机)是从法国汤普森公司引进的。它是用数字仿真技术对大亚湾核电站主控制室进行1:1高保真模拟的大型设备,用于培训核电站的操作运行人员、系统分析包括对操作规程的验证等。模拟机的 I/O 接口系统是计算机与各种开关、仪表交换信息的桥梁。本文力求从数据传输的角度,结合程序流程图论述 I/O 接口系统的工作原理。

The full scope simulator in Daya Bay Nuclear Power Stationis imported from THOMSON-CSF company in France.It is alarge facility,using digital simulation technology,that simulatethe main control room of Daya Bay Nuclear Power Station withthe high fidelity.It is used for training operators;systemanalyzing including operation procedure verification.The inputoutput interface system of the simulator is the bridge of theinformation exchang between instrumentation and the computer.From the point of view of data transfer,this paper discussesthe operation principle of the I/O interface system.
