摘　　要：首先,阐述了我国现有的区域供水系统的概况,指出传统的供水系统难以满足人们生活中对水量的需求变化的要求。然后,提出了根据供水的水压自动的进行供水泵的启动和停止的切换,从而实现水压自动调节变化。而后归纳总结了供水泵的故障现象,针对其故障状态建立了故障树。最后,利用LabVIEW仿真实现了供水系统的自动调节和故障诊断的仿真,通过仿真软件的结果证明系统设计的方法能够实现各个供水泵的自动切换并且能够准确的对供水泵产生的故障给出实时诊断结果。This paper describes an overview of the regional water supply system. Firstly, pointed out that the traditional water supply system can not meet the changes requirements for water. Therefore, according to proposed water supply pressure conducted for automatic start and stops the pump. Thus automatically adjust the water pressure. Then summarizes the failure phenomenon for pump, establish the fault tree for phenomenon. Finally, realize Simulation of automatic adjustment and troubleshooting for water supply system based on LabVIEW, the system certificate that supply pump can automatically switch and gives real-time diagnostics for the fault by the results of simulation.
