The frequency conversion variable-speed variable-variable water supply and data acquisition and processing system was designed and researched. The CAD network was used to calculate the pipe network adjustment, and the mathematical model of the most unfavorable point pressure control of the pipe network in different flow sections was established and programmed. In the parallel operation environment of the controller, frequency conversion governor and water pump, the variable pressure variable adjustment of the water supply operation is realized, so that the water supply system is in the best working condition, and the utility model solves the problem of water and electricity waste that is currently being applied to the constant pressure variable water supply method. The problem reached the ideal energy-saving goal for water supply operation. At the same time, this article also adopts the means of communication connection to realize real-time communication and motion control between the lower computer and the host computer and the programmable controller, and achieves the purpose of automatic data collection, storage, processing and dynamic monitoring, and improves the water plant. The modern management level.
