摘　　要：为了建立一个具有良好的可扩展性和可维护性的系统,必须有一个具有高度可复用性和灵活性的设计。设计模式代表了成功的可复用的优秀设计经验,在系统设计中引入设计模式将有效的提高系统的可扩展性和可维护性。首先简要分析了设计模式,然后介绍了数据采集系统的功能、体系结构,并详细描述了工厂方法模式、观察者模式、单件模式在数据采集系统中的应用。经实践检验,设计模式的应用,使得软件系统的开发效率和软件系统的质量都得到了很大的提升。该方法具有较高的理论和实践意义。In order to develop a good scalable and maintainable system, there must be a architecture with high degree of reusability and flexibility. Design patterns represents excellent and reusable design experience. Application of design Patterns in system design will enhance the scalability and maintainability of the system effectively. This paper briefly describes the signification of design pattern at first, and explains the function and structure of data acquisition system. It describes the application of factory method pattern, observer pattern, singleton pattern in the system detailedly. The practical result verifys that application of design patterns in system design improves development efficiency and the quality of .software systems. This method have certain theoretical and practical significance.
