The invention discloses a novel industrial process automation control system and method, and the industrial process automation control system comprises a signal transponder for forwarding the controlincrements of control components in an industrial process; a central processing system; and incremental PID controllers, wherein the number of the incremental PID controllers is the same as the numberof the control components, and the incremental PID controllers are in one-to-one correspondence with the control components. Each incremental PID controller is connected with the corresponding control component, and the signal transponder is connected with a computer through a normally opened contact of a cycle time relay. The central processing system comprises a computer, a comparator, and an oscilloscope. The computer is connected with the oscilloscope, and the comparator is connected with an internal bus of the computer. Through combining with the control method, the system can iron out the defects that feedback signals cannot be comprehensively controlled, and is not high in automation degree. The system can achieve the real-time and stable detection of the increments of the controlcomponents, and avoids the potential risks caused by the large fluctuation of the increments.
Description
technical field [0001] The invention belongs to the technical field of industrial process automation, and in particular relates to a novel industrial process automation control system and control method. Background technique [0002] At present, in the industrial process, the industrial process can often be subdivided into several control components, and the control components generally have three types of actions: first, synchronous action. If the industrial process is composed of two control components, the two control components start synchronously, and the If the other two control components stop operating, the industrial process will stop running. If one of the control components does not stop operating, the other control component stops operating, and the other control component can cooperate with the non-stop operating control component to operate; Second, sequential operation, if the industrial process is composed of two control components, but one of the functional ...
