【摘要】 设计了一套基于可编程逻辑控制器(PLC)自动控制的自动供水系统，从系统硬件设计与系统软件设计2个方面对系统设计进行介绍。用户可以在中控室远程监控水源井电流、流量及液位等实时信息。对水源井各种供水参数进行远程自动监控，系统能根据用户程序控制逻辑自动监视输入，并随时更改输出状态，对水源井泵的自动起停状态进行远程控制，提高供水效率，减少水源损失，从根本上确保供水质量，实现对供水系统的自动控制和计算机对现场监控的管理。更多还原

【Abstract】 A set of rural automatic water supply system based on PLC automatic control is designed, and the system design from two aspects of system hardware design and system software design is introduced.Users can remotely monitorthe current, flow and liquid level of the water source well in the central control room.Through the realization of remote automatic monitoring of various water supply parameters of the water source well,according to the user program control logic,the input state can be automatically monitored and the output state can be changed at any time.The automatic start and stop state of the water source well pump is remotely controlled,which improves the efficiency of water supply,reduces the loss of water source,and fundamentally ensures the quality of water supply.It realizes the automatic control of water supply system and the management of computer on-site monitoring.更多还原
