本文指出我国设备自动化系统存在的主要问题是将系统的集成作为弱电集成，导致自动化系统和设备系统相脱节。分析了设备自动化系统集成的目标、阶段划分及其评价标准。提出防护工程自动化系统与设备系统一体化集成的方法：瞄准设备自动化系统预期目标，在设计、施工、编程调试各个环节，甚至产品开发阶段，必须密切加强自动化系统与设备系统配合。

This paper points out the main issue of our building automation system is that the system has been integrated as weak current, which leads to be incompatibility between automation system and facility. It analyses the integration objectives, phrasing and evaluation criterion of facility automation system, and proposes the integration method about automation system and facility system in protective engineering, which aimed at the function of system, enhanced the coordination between automation system and facility system in all aspects of design, construction, programming and debugging, and even the development stage of product and management strategies.
