空分装置计算机控制系统的硬件设计

The Hardware Designing of the Computer Control System of Air Separation Device

介绍了空分装置计算机控制系统的硬件设计方法 ,主要包括以下几个部分。计算机控制系统硬件设计依据 :有输入输出信号的类型和点数 ,控制回路 ,顺序逻辑控制 ,联锁控制。控制系统的选择 :选择计算机控制系统时除考虑要满足工艺要求和控制功能外 ,还考虑性能价格比 ,技术支持 ,开放性。模板的选择 :主要包括CPU模板、电源模板、机架间连接模板、I/O模板等。信号地址的确定

The hardware designing method of the computer control system of 6?000?m 3/h air separation device is described. It the type of involves the follow principle contents. The basis of computer hardware designing includes the types and points belong to I/O sign,control cycle,order logical control,interlock control. The selection of control system satisfies not only technics needs and control founction,but capability price rate?technic support and opening performance. The selection of module includes CPU templet?electric source?frame-saw connect and I/O. The signal address defining of the computer control system contacts with the distribution of the I/O.
