摘　　要：为了研制基于低功耗的ARM硬件架构的嵌入式系统的103协议主站通信控制器,需对原有103通信程序作结构化、精简化移植改造。将有限状态机(FSM)模型引入规约状态管理中。从有限状态机模型的定义出发,讨论了状态、转移函数及事件集合等概念和在规约实现中的具体应用。提出了采用状态搜索树来扩展FSM的行为方式,为提高主站的响应速度奠定基础。提出了分步式轮询应答及采用历史状态响应中断操作的实现方式,进一步提高了主站的响应速度,解决了以往通信程序采集模型周期长、状态管理困难等问题。In order to develop a 103-protocol master communication controller based on a low-power ARM hardware architecture embedded system,the original 103 communication program porting modification needs to be structured and streamlined.The finite state machine(FSM)model is introduced into the statute state management.From the definition of the FSM model,the specific applications of the concepts of state,transfer function and event set in the statute implementation are discussed.A state search tree is proposed to extend the behavior of the FSM to lay the foundation for improving the response speed of the master.The implementation of stepwise polling response and the use of historical state response interrupt operation are proposed to further improve the response speed of the master station and solve the problems of long cycle time and difficult state management of the previous communication program acquisition model.
