Abstract: Based on creation pattern and requirements of the telemeter reading system, characters of factory pattern, singleton pattern and builder pattern are analyzed, and the thinking of OOD is introduced. This paper proposes the novel solutions of multi protocol with system expansibility, spending and encapsulation. The problem of the long-distance telemeter reading is solved completely and efficiently.

Key words: Factory pattern, Singleton Pattern, Builder pattern, Protocol, Software reuse

摘要： 电力行业的远程抄表系统中涉及的表计规约众多，传统的设计模式与开发方法难以满足应用需求。论文在介绍创建性模式概念和相关技术的基础上，结合远程抄表系统中实际应用的需求，从面向对象的设计思想出发，着重分析了工厂模式、单例模式和建造模式的特点，并从扩展性、系统开销大小和封装继承等方面对多规约处理问题提出几种模式融合的解决方案。
