The invention discloses an unattended controller and a control method of a regional pressurized pump station for urban water supply. The controller includes: a data acquisition module for collecting data; an expert module for setting the low water level of a storage tank and the set value of the high water level, and set the set value of the water delivery pressure in each period according to the user's needs; the prediction module is used to conduct time series analysis and predict the future according to the historical measurement data and current measurement data of the outlet water flow of the pressurized pumping station The water output per unit time of each time period within a period of time, and divide the peak water consumption period and the low water consumption period; the dispatching module is used to calculate the liquid level in the reservoir to reach the high water level before the peak water consumption period, and after the peak period ends The water intake per unit time of each period when the liquid level in the reservoir drops to a low water level, and adjust the water intake valve opening of the booster pump station according to the water intake per unit time of each period to adjust the water intake. The invention can realize the scientific scheduling of water supply pressure and flow of the pressurized pumping station.
Description
technical field [0001] The invention relates to the technical field of urban water supply, in particular to an unattended controller and a control method of a regional pressurized pumping station for urban water supply. Background technique [0002] In order to solve the phenomenon that the water supply pressure in the ever-expanding remote areas of the city is not enough to supply water to the local residents normally, the method of adding regional pressurized pump stations for secondary pressurization is usually used to solve the water supply problem in this area. The regional pressurized pump station is mainly composed of water inlet pipe, water inlet valve, reservoir, water pump, outlet pipe, water outlet valve and corresponding automatic control and monitoring system. Turn on the T access on the main road. [0003] However, the existing pressurized pumping stations basically use time-based constant pressure water supply and manual control of the water intake and output...
