摘　　要：FMS控制系统传统的开发方式不够灵活,面对需求的改变,维护困难、扩展能力差,运用设计模式能生成易维护、易扩展、易复用、灵活性好的系统,文章以控制流程为例,用状态模式进行了说明,状态模式把状态的判断逻辑转移到表示不同状态的一系列类中,把复杂的逻辑简单化,在业务流程做出改变之后,用这一模式可以很快的对客户的需求做出响应,更改流程变的更加明晰和简便。FM S control systems developed by traditional approaches were not flexible to use when it comes to the changes of demanding, Design pattern is employed to improve the programming method so a system constructed, as a result, which is easy to maintain, to expand and reuse. Taking the controlling flow as an example, this paper describes the process to construct the FM S control system. State pattern, which transform the judge logic of the state to a series of classes, make the raw complex logic much easier. When the business flow was modified, system mentioned above can respond to customer＇s demands swiftly, and the change to system is more convenient.
