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. The system also has a loading protection function. The system has a low pressure alarm and highpressure alarm, if the system is often to remind the water pressure is too low, you need to remind the user to the need for additional pumps to ensure that the normal water supply system to remind the water pressure high, the user can manually turn off all pumps. The design is the property of PLCbased water supply system, through the debugger to show that this system can meet the design requirements and have a good value in use.
