Distribution controlling method capable of configuring chemical valve chest

Abstract

The invention provides a distribution controlling method capable of configuring a mechanical valve chest. The method provides a microcomputer parameter control system, at least one intelligent chemical valve chest distribution system and a plurality of chemical supply systems, wherein the microcomputer parameter control system is connected with the intelligent chemical valve chest distribution system and the plurality of chemical supply systems; the intelligent chemical valve chest distribution system is connected with the plurality of chemical supply systems; and the plurality chemical supply systems supply a chemical reagent to a used bench through a manifold tank and the chemical valve chest by means of a chemical pipeline respectively. In the method, related control parameters are set by the microcomputer parameter control system, the plurality of chemical supply systems can be driven and controlled through the intelligent chemical valve chest distribution system, and the control parameters of the intelligent chemical valve chest distribution system can be uploaded or downloaded and edited, so that the control cost of the chemical supply system can be saved.

Description

technical field [0001] The invention relates to a chemical control system, in particular to a control method of the chemical control system. Background technique [0002] Such as figure 1 As shown, in chemical factories, semiconductor factories and petrochemical factories, in various preparation processes, at least one chemical supply system 1 needs to be used to provide various chemical reagents to meet the requirements of the preparation process. [0003] The chemical supply system 1 is connected to a microcomputer parameter control system 7, and through a chemical pipeline 8, passes through a branch box 6 and a chemical valve box 2 to supply chemical reagents into a use machine 3. The chemical valve box 2 generally passes through an electromagnetic The control of the valve box 5 is to determine whether to add chemical reagents. Each chemical supply system 1 needs a parameter controller 4 of its own. The parameter controller 4 is equipped with control parameters. The para...

Problems solved by technology

[0004] Therefore, if the preparation process is complex and requires the use of multiple chemical supply systems 1 to add various chemical reagents into different use machines 3 or the same use machine 3, the same number of parameter controllers 4 must be configured, which will cause the chemical supply system 1 high cost of control

[0005] The known parameter controller 4 is directly arranged on the chemical supply system 1 to form an integral body or is directly arranged beside the chemical supply system 1 for the user to directly set various parameters, so each parameter controller 4 has a corresponding The control program written for the chemical supply system 1, when there is a change in the preparation process and the dosage of the added chemical reagents needs to be changed, in the prior art, the parameter controller 4 can only be changed one by one or directly replaced, which is time-consuming and labor-intensive. Meet the needs of users
