Sequential control configuration method of water processing system

Abstract

The invention discloses a sequential control configuration method of a water processing system. The method comprises a main program, all subprograms, an automatic entire filter system startup program,and an automatic entire filter system stop program. The all filter sequential control subprograms include single cell filter subprograms, single cell filter backwashing programs, and single cell filter stop subprograms. According to the invention, all subprograms are nested into the main program and manual, program-control and step-control selection buttons are added. The operator can select onefilter cell randomly based on the actual need to carry out backwashing in a forced manner, so that the flexibility and convenience of operation control are enhanced. Since a backwashing application signal, a backwashing end signal, and priority determination are introduced into the sequential control, only one filter cell is in a backwashing state at the same time and each filter cell can carry out backwashing timely based on a time sequence, so that the device is protected, the service life of the device is prolonged effectively, the work efficiency of the operator is improved substantially,and the labor intensity is reduced.

Description

Technical field [0001] The invention relates to the technical field of water treatment control programs, in particular to a sequential control configuration method of a water treatment system. Background technique [0002] At present, the process sequence control operation of the 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 means are 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 large negative impact on the project's operation and management benefits. Summary of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a sequential control configuration method for a water treatment system. Each subprogram is nested in the main program, and manual, ...
