虽然采用过程控制计算机来代替分离的调节器有很大的吸引力,但是为了生产过程的安全,模拟后备几乎总是不可缺少的。而模拟调节器与数字计算机之间的连接并不是一件容易的事。下面来谈谈模拟后备控制和计算机有关的硬件与软件的问题。
Although the use of process control computers to replace discrete regulators has great appeal, but for the safety of the production process, the analog back-up is almost always indispensable. The connection between the analog regulator and the digital computer is not an easy task. Here to talk about analog backup control and computer-related hardware and software issues.
