封闭型集散系统在运用APC控制时应注意的问题及解决方法

Problems desevring attention and ways of solving them in applicotinms of APC in close-loop control system

先进工艺控制 (APC)在封闭型集散系统上运用时会产生如何连网 ,外部电脑中的APC控制程序与原有封闭型集散系统之间怎样进行无扰动切换等问题 ,通过采取操作系统升级 ,设置看门狗 ,实时跟踪等措施可以加以解决。

When APC (advanced processing control) is applied in a close-loop distributel conerol system, some problems appear: how to link with internet? How to switch smoothly between APC in outside computer and the early a close-loop distributed control system? A series of measures have been taken to solve these problems, such as upgrading the operating system, setting watchdog, real-time tracking and so on.
