摘要
通过分析工控系统的特性,提出采用状态机的思想进行工控软件设计。详细论述了高速状态机的错步问题以及控制层中状态机的状态划分问题。结合具体的应用实例,给出了基于状态机的实现方法。实验表明,采用状态机的设计方法有助于准确描述受控对象的行为,软件的健壮性和可靠性得到显著提高。
A new method of using FSM (finite state machine) to implement the design of industrial controlling software is proposed by analyzing the special character of it. The "error step"of high speed state machine and the state partition of state machine are dis- cussed in details. Combining practical examples, the state machine based design is given. Experiment result verifies that the object behavior can be described much more precisely by state machine based controlling software, meanwhile, the robustn...
