随着工业设备在复杂控制领域的不断发展，其控制系统越来越庞大。为了降低系统设计的复杂度，针对嵌入式控制系统的特点进行研究，提出了一种基于WinCE系统的流程场景化设计方法。该方法以应用场景为基础配置工作流程，通过有限状态机和多线程技术结合来实现动作机构自动化运行，并将其应用到触摸式工业分析仪控制系统的设计中。研究结果表明，该方法具有业务集中、结构松耦合、代码复用效率高的优点，适用于嵌入式控制系统的开发。%With the development of industrial facilities in sophisticated control field,related control systems are becoming increasingly large. In order to reduce the complexity of system design, the characteristics of embedded control systems are studied and a process scenarios design method based on WinCE is proposed. On the basis of application scenarios, the workflow is configured; automatic operation of actuating mechanism is implemented by combining finite state machine with multi-thread technology. The method is also applied in the design of control system of touch-type industrial analyzer. The result of research shows that the method has many advantages,including business concentrated, structure loosely coupled,and high efficiency of code reuse;it is suitable for development of embedded control systems.
