Intelligent power-saving control method for water supply pressurization

Abstract

The invention relates to the technical field of constant-pressure water supply, in particular to an intelligent power-saving control method for water supply pressurization. The method comprises the following steps that parameters required by intelligent power-saving control through an upper computer management system are edited and then sent to a power-saving control terminal through GPRS (General Packet Radio Service) in a wireless mode, the power-saving control terminal collects local water supply pressure, local instantaneous flow in real time and water supply network coefficients, the local water supply pressure is controlled through calculation, and an actual value of the pressure of the most unfavorable point is adjusted to be consistent with a target value. Under the condition that normal water supply is not affected, the operation speed of a booster pump is controlled through collected local pressure and local instantaneous flow through operation output, variable-pressure operation of the local water supply pressure is achieved so as to achieve far-end constant-pressure operation, and therefore the purpose of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of constant pressure water supply, in particular to a control method for water supply pressurization and intelligent power saving. Background technique [0002] At present, the energy-saving method of water supply stations is that experienced staff adjust the outlet pressure of water supply stations in real time according to seasonal changes and people's water habits. In winter, the water consumption is small, and the management personnel of the water supply station, according to experience, reduce the water supply pressure at the outlet of the water supply station to ensure that the village can use water normally; according to experience, during the daily peak water supply period Setting a different water supply pressure from the low water supply period will increase the labor intensity of the staff at the water supply station, and it will not be possible to accurately save energy and save water. The water ...

[0002] At present, the energy-saving method of water supply stations is that experienced staff adjust the outlet pressure of water supply stations in real time according to seasonal changes and people's water habits. In winter, the water consumption is small, and the management personnel of the water supply station, according to experience, reduce the water supply pressure at the outlet of the water supply station to ensure that the village can use water normally; according to experience, during the daily peak water supply period Setting a different water supply pressure from the low water supply period will increase the labor intensity of the staff at the water supply station, and it will not be possible to accurately save energy and save water. The water consumption varies greatly, and it is difficult for the staff at the water supply station to accurately judge the required water supply pressure. Setting the pressure too high is wasteful. Electric energy, the setting pressure is too small, which will affect the water consumption of users at the most disadvantaged point. Experienced technicians are required to adjust the water supply pressure in time according to the season, temperature, and user water habits. The adjusted water supply pressure may not meet the needs of users, and often The staff of the water supply station should adjust the water supply pressure immediately if the feedback from the user is that the pressure is insufficient or there is no water.
