河南理工大学 《可编程控制器原理及应用》设计报告 PLC的物业供水系统 成 员:王彦凯 李 强 王翱翔 专业班级: 电仪09-3班 指导老师: 杜静静 所在学院:电气工程与自动化学院 2012年6月 14日 摘 要 随着我国社会经济的发展,住房制度改革的不断深入,人们生活水平的不断提高,城市中各类小区建设发展十分迅速,同时也对小区的基础设施建设提出了更高的要求?小区供水系统的建设是其中的一个重要方面,供水的经济性?可靠性?稳定性直接影响到小区住户的正常生活和工作,也直接体现了小区物业管理水平的高低?传统供水方式普遍不同程度的存在效率低?可靠性差?自动化程度不高等缺点,难以满足当前经济生活的需要? 本论文针对住宅小区的供水要求,设计了一套由可编程逻辑控制器PLC?四台水泵?压力传感器等主要设备构成的全自动供水系统,系统分为手动模式和自动模式?自动模式,首先由传感器把信号传给PLC,再由PLC根据水压的高低,分析控制四台水泵的工作状态;手动模式下,可以通过各个水泵的启动停止按钮独立的工作?该系统还设有过载等保护功能?该系统设有低压报警和高压报警,如果系统经常提醒水压过低,那就提醒使用者需要增设水泵以保证供水的正常,如果系统提醒水压偏高,使用者可手动关掉所有水泵?本设计是基于PLC的物业供水系统,通过调试表明本系统能够满足设计要求并有很好的使用价值? 关键字: PLC 物业供水系统 Abstract With the development of Chinas socio-economic, housing system reform is the deepening of the continuous improvement of peoples living standard, various types of residential construction and development in the city very quickly, but also put forward higher requirements for the districts infrastructure. The construction of the residential water supply system is one of the important aspects of water supply in the economy, reliability, stability directly affect the normal life and work of the district households, but also directly reflects the level of residential property management. The traditional way of water supply in general the presence of varying degrees of efficiency, poor reliability, degree of automation, disadvantages, it is difficult to meet the needs of the current economic life. This thesis focuses on the residential quarters of the water supply requirements, design the automatic water supply system consisting of a programmable logic controller PLC, four water pumps, pressure sensors, and other major equipment, systems work hours of manual operation and automatic operation, automatic operation, the first signals to the PLC by the sensor according to the level of water pressure signal from the PLC to control the working status of the four water pumps; manual operation by the start of each pump stop button to work independently.
