A knowledge based scada system for agricultural process control

摘要

This approach leads to the design design of a digital control system with generalized functions for process control, configurable to meet greenhouse control requirements. Intelligence is shared among low level control loops in the controller and high level decisions made at the central process computer. The system can operate in "central mode", "remote control" or "hybrid mode". The development of an open Knowledge Based System in the form of tasks and subtasks, provides an elegant way of rapid program development.
