A single-chip microcomputer water treatment system based on plc control program

Abstract

The invention relates to a single-chip water treatment system based on PLC control program, which includes the following processing steps: S1: collecting external signals and setting time parameters; S2: parameter integration; S3: parameter display; S4: operation; S5: liquid level Detection; S6: water pump stop; S7: valve work; S8: water pump work; S9: alarm; S10: water treatment equipment work. The device of the present invention is simple, beautiful, easy to maintain, convenient to repair and replace, and only needs to return to the factory to replace the main board in case of failure; multi-point automatic conversion saves space and human resource costs; the output port is designed as an LED touch screen to realize data reading, Quick command operation; low cost; the invention can be better applied to UF, RO, carbon filter, sand filter and other pure water, waste water, waste water recovery and treatment processes, and can identify abnormal fault points of equipment relatively simply and quickly, which is convenient for equipment maintenance and management.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a single-chip microcomputer water treatment system based on a PLC control program. Background technique [0002] The microcomputer controller used in the water treatment process is a device based on the PLC control program system. At present, PLC technology at home and abroad has been widely used in various industries such as steel, petroleum, chemical industry, electric power, building materials, machinery manufacturing, automobile, textile, transportation, environmental protection and cultural entertainment, and its development is towards high-speed processing and small modular structure. , and constantly enhance the communication function, and the programming is increasingly rich. [0003] However, microcomputer control systems used in ultrafiltration, reverse osmosis, carbon filtration, sand filtration and other pure water, wastewater, and wastewater recycling processes often...

AI Technical Summary

Problems solved by technology

[0003] However, microcomputer control systems used in ultrafiltration, reverse osmosis, carbon filtration, sand filtration and other pure water, wastewater, and wastewater recycling processes often use multi-path conversion to achieve water treatment, which is difficult to achieve simplification and intensive Miniaturization and miniaturization, and it is difficult to operate, maintain and repair
