Sequence Control Configuration Method of Water Treatment System

Abstract

The invention discloses a sequential control configuration method for a water treatment system, which includes a sequential control main program, each subroutine, an automatic start program for the entire filter system, and an automatic stop program for the entire filter system. The subroutines for the filter sequence control in the present invention include : subroutine for single-cell filter filtration, single-cell filter backwash program, and single-cell filter stop subroutine. The present invention nests each subroutine in the main program, adds manual, program control, and step control selection buttons, and the operator can also select a filter tank for forced backwashing according to actual needs, which increases the flexibility and convenience of operation control The backwashing application signal, backwashing end signal, and priority judgment introduced in the sequence control ensure that only one filter tank is in the backwashing state at the same time, and ensure that each filter tank can be backwashed in time according to the sequence. It protects the equipment, effectively prolongs the service life of the equipment, significantly improves the work efficiency of the operators, and reduces the labor intensity.

Description

technical field [0001] The invention relates to the technical field of water treatment control programs, in particular to a sequential control configuration method for a water treatment system. Background technique [0002] At present, the process sequence control operation of water treatment system is becoming more and more complicated. The general distributed control system (DCS) and programmable logic controller system (PLC) sequence control configuration operation method is single, the robustness is poor, and the degree of automation is not high. It greatly wastes the energy and time of the operators in the central control room, and has a considerable negative impact on the operation and management benefits of the project. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a sequential control configuration method for the water treatment system. Each subroutine is nested in the main p...
