基于PLC控制的大楼物业供水系统设计 10届毕业生毕业设计成果 PAGE PAGE 6 摘要 供水系统是现代化城市的重要基础设施，是为城市人民生活和经济发展提供满足不同需求的供水水量、水质和水压。因此供水工程是维系人类生存发展的生命系统工程。城市中各类小区的建设发展十分迅速，同时也对小区的基础设施建设提出了更高的要求，小区的供水系统是其中的一个重要方面。本设计是针对供水要求设计的基于PLC控制的大楼物业供水系统设计系统。 本设计详细介绍了大楼物业供水系统的方案设计、硬件选择、软件规划和编写，并重点描述了大楼物业供水系统的工作原理、系统设计、软件编程的原则和技巧。 本设计介绍了大楼物业供水系统的基本原理以及工作流程。具体说明了可编程序控制器在大楼物业供水系统中的作用。程序涉及到了大楼物业供水系统工作的绝大部分过程。利用PLC控制的大楼物业供水系统提高了系统的稳定性，保证大楼物业供水系统能够长期稳定运行。 最终完成的大楼物业供水系统具有平稳运行、节能等主要功能，整个系统的开发体现了在设计数字控制系统的灵活性、实用性。 关键词：供水系统，PLC，水压，稳定，可编程序控制器 Abstract The water supply system is the modernization of the important infrastructure in the city, for the city peoples life and economic development to provide to meet the different needs of water quantity, water quality and water pressure. So the water supply project is to maintain the survival and development of human life system engineering. City of residential construction development is very rapid, but also on the community infrastructure construction raised taller requirement, small water supply system is one of the important aspects. This design is for the water supply requirement design based on the PLC control property building water supply system design system. The detailed design of the building property of water supply system design, hardware selection, software design and write, and describes the property building water supply system working principle, system design, software programming principles and techniques. This design introduced the building property water supply system the basic principle and workflow. Detailed description of the programmable controller in the water supply system in the role of building property. The procedure involved the building property of water supply system of most of the course work. Using the PLC control property building water supply system improves the stability of the system, to ensure that the building property water supply system can run stably for long term. The final building property water su
