Remote operation parameter regulation and control method applied to constant-pressure water supply system

Abstract

The invention discloses a remote operation parameter regulation and control method applied to a constant-pressure water supply system. A single-chip microcomputer module, a data operation unit, a data control unit, a data receiving unit and a data scheduling unit are adopted as remote operation parameter regulation and control tools applied to the constant-pressure water supply system. The remote operation parameter regulation and control method applied to the constant-pressure water supply system comprises three steps. Based on a PLC control subsystem of an existing secondary water supply system, only a small number of components are added, so that the overall cost is low and the use is convenient; the data scheduling unit can conveniently control pressure threshold data of a PLC at the far end in application; the PLC controls a water pump to keep relatively low water amount and low water pressure in the low-peak time period of water use to supply water to a user side pipeline, so that the energy-saving purpose is achieved; and the frequency of a frequency converter can be improved in real time under the condition that the PLC does not change an original pressure setting threshold value in the high-peak time period of water use, so that the rotating speed of the water pump is increased, the power is increased, the water pressure of a user side is increased, and normal water use of high-rise residents in the high-peak time period of water use is guaranteed.

Description

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

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.
