A remote control operation parameter method for constant pressure water supply system application

Abstract

A method for remotely adjusting and controlling operating parameters in a constant-pressure water supply system, using a single-chip microcomputer module, a data calculation unit, a data control unit, a data receiving unit, and a data dispatching unit as tools for remotely adjusting and controlling operating parameters in a constant-pressure water supply system; constant-pressure water supply The method for remotely controlling the operating parameters of the system application is divided into three steps. The present invention is based on the PLC control subsystem of the existing secondary water supply system, only a small number of components are added, the overall cost is low, and the use is convenient. The PLC controls the water pump to maintain a relatively low water volume and low water pressure to supply water to the user-side pipeline to achieve the purpose of energy saving; during the peak water consumption period, the PLC can increase the frequency of the inverter in real time without changing the original pressure setting threshold, and thus the water pump. The speed increases, the power increases, and the water pressure on the user side increases, thereby ensuring that high-rise residents can use water normally during peak water consumption periods.

Description

technical field [0001] The invention relates to the technical field of secondary water supply systems, in particular to a method for remote control of operating parameters applied to a constant pressure water supply system. Background technique [0002] The secondary water supply system of high-rise buildings is a facility that pressurizes the tap water under pressure so that the residents of high-rise buildings can use the tap water normally, and provides guarantee for the residents of high-rise buildings to use water. When the existing secondary water supply system of high-rise buildings is working, the supporting pressure sensor monitors the water outlet pressure on the side of the water pump outlet pipe (connected with the user's pipe) of the secondary water supply system in real time, and then transmits the pressure signal (4-20mA current signal) to the secondary water supply system. PLC and other water supply control subsystems supporting the secondary water supply sys...

Problems solved by technology

[0004] In order to overcome the disadvantages that the PLC control subsystem used in the existing secondary water supply system cannot adjust the PLC water pressure setting threshold according to the user's water consumption, which leads to the fact that the user's water consumption cannot be effectively guaranteed during the peak period, the present invention provides a system based on the existing secondary water supply system. The PLC control subsystem of the water supply system only adds a small number of components, the overall cost is low, and it is easy to use. In the application, the pressure of the water pressure sensor is collected in real time and transmitted to the remote end. The data dispatching unit can conveniently control the pressure threshold of the PLC at the remote end. Data, PLC controls the water pump to maintain relatively low water volume and low water pressure to supply water to user-side pipelines during the peak water consumption period to achieve the purpose of energy saving. After switching, the offset current signal data can be output to simulate the pressure data of the secondary water supply system pressure sensor and enter the PLC signal input terminal, so that the PLC can increase the frequency of the inverter in real time without changing the original pressure setting threshold, and then the water pump Increased speed, increased power, and increased water pressure on the user side ensure that high-rise residents can use normal water during the peak water consumption period.
