A pickling process control system based on precise control as claimed in claim 6, characterized in that: The environmental impact effect assessment module is used to obtain environmental data of the pickling process and import it into the environmental impact effect assessment model to perform environmental impact effect assessment. The pickling time analysis module is used to obtain oxidation effect assessment results and environmental impact assessment results and import them into the pickling time analysis model to perform pickling time analysis. The pickling process control module is used to control the module to control the pickling process according to the pickling time obtained by analysis. The general control module is used to control the operation of the data acquisition module, the oxidation effect assessment module, the environmental impact effect assessment module, the pickling time analysis module and the pickling process control module.

8. An electronic device, comprising: A processor and a memory, wherein the memory stores a computer program that can be called by the processor; It is characterized in that the processor executes the pickling process control method based on precise control as described in any one of claims 1 to 5 by calling the computer program stored in the memory.

9. A computer-readable storage medium, characterized in that: Instructions are stored, and when the instructions are run on a computer, the computer is caused to execute a pickling process control method based on precise control as described in any one of claims 1 to 5.
