Abstract
The invention discloses a control system of an oil removal device. The control system adopts control combination of an IPC (Industrial Personal Computer) and a PLC (Programmable Logic Controller), is very suitable for the field of industrial automation, is strong in controlling stability of the oil removal device and high in reliability, and can be widely generalized and applied in the industrial wastewater treatment.
Description
Technical field
The present invention relates to field of software development, be specifically related to a kind of control system of oil removal plant.
Background technology
Along with industrial expansion, the discharge capacity of oily sewage grows with each passing day, and the harm of environment is on the rise.Contained oily substance in oily waste water, comprises natural oil, petroleum products, tar and fraction thereof, and edible animals and plants oil & fat class.From concerning the pollution of water body, be mainly oil and tar.The concentration difference of the contained oily substance of waste water that different industrial sectors are discharged is very large.As the waste water producing in oil refining process, oleaginousness is about 150～1000 mg/litre, and in Coking Plant Wastewater, tar content is about 500～800 mg/litre, and the tar content in the waste water that gas generating station is discharged can reach 2000～3000 mg/litre.If oily waste water is not recycled, can cause waste; Enter river, lake or bay, meeting polluted-water, affects hydrobiont existence; For agricultural irrigation, can stop up interstices of soil, hinder crop growth.
Adopt now the processing of oily sewage gradually to enter robotization control flow, but control system imperfection are ripe, last treatment effect neither be very desirable.
Summary of the invention
The present invention is directed to above problem provides a kind of control system of oil removal plant, this control system adopts the control combination of industrial computer and PLC, be highly suitable for industrial automation, the stability of controlling oil removal plant is strong, reliability is high, can be applied in Industrial Wastewater Treatment widely.
Object of the present invention reaches by the following technical programs:
A control system for oil removal plant, comprises industrial computer, PLC, load module and output module, and described industrial computer is host computer, in order to human-computer interaction interface platform to be provided; Described PLC is slave computer, and PLC carries out communication by bus and industrial computer, and the signal of the load module detecting is passed to industrial computer, and industrial computer is inputted issuing command to PLC according to user, and PLC responds user instruction and outputs signal to output module and completes control.
Also comprise A/D modular converter and D/A modular converter, A/D modular converter is all connected with PLC with D/A modular converter, and described A/D modular converter is connected with load module, and D/A modular converter is connected with output module.
