A method for controlling tanning process based on recipe software

Abstract

The invention discloses a tanning process control method based on formula software, which comprises the following steps: step A, formula software; step B, equipment control station; step C, monitoring. In the tanning production line of the present invention, the operator can monitor two production equipments by each person in the past, and each operator can monitor eight production equipments. 16 devices in a production line can be inspected by only three operators, which reduces the number of staff, reduces labor intensity, improves product consistency, and greatly reduces the safety, economy, and stability of the production system. Reduce labor costs and reduce error rates. In addition, the process management personnel can modify, add, delete the actions and parameters of the formula, edit and add new formulas according to different needs, and do not need to change the program of the equipment control station, which solves the problem of the original solidified formula, many personnel interventions, and the program Disadvantages such as large changes.

Description

technical field [0001] The invention relates to a process control system, in particular to a formula software-based tanning process control method, and belongs to the technical field of tanning application in the fur industry. Background technique [0002] With the continuous development of industrial automation, PLC and DCS (Distributed Control System, distributed control system) are widely used in various industries, and the control system is gradually developing towards fine control. The demand for industrial automation is more diversified. The traditional sequential control method , has been unable to meet the needs of production for product upgrading. [0003] In the fur industry, the tanning production line has a large number of identical production equipment, and the equipment is relatively independent. Different production lines can produce different leather types, and even the same production line can produce different leather types. Different leather types requir...

Problems solved by technology

[0006] (2) One or several fixed formulas can no longer meet the requirements of product changes for process control changes

The control method that relies on manual intervention has high requirements for the quality of employees, the number of employees is large, the labor cost is also a great waste, and the error rate is also high, and the product quality is uneven.

[0007] (3) Different PLC brands have control schemes based on S88 flexible formula, but the implementation method has high requirements on the system, high cost, large waste, and the connection between equipment is too strong, and the impact of the main system failure on the entire production line If it is too large, it does not meet the characteristics of relatively independent tanning process equipment. Therefore, to solve the above problems, a tanning process control method based on formula software is proposed.
