The mixer has gradually developed from the classical PID regulation, feedback and feedforward loop control to run-to-run control, distributed control, object-oriented optimization control and artificial intelligence control to multi-parameter and multi-objective control. To correct and compensate it, the algorithm needs to be more and more detailed and accurate, which is particularly important. The optimal control, adaptive control or artificial intelligence of batching and mixed objects are realized by the computer distributed control system itself, and no other computer hardware is attached.

The feeding system is a Weighing system composed of IPC and network communication. The requirement for the support of batching is not only how powerful and rich its functions are, but also the demand for the redevelopment ability of users with different objects is becoming more and more important.

According to the different requirements of each special control object, it can realize its own control strategy, which will provide an important means for the pertinence of the industry. Now sort out the plan of batching control and see if it can help in the batching process of different industries.

(1) Intelligent weighing instruments are widely used in the field, and all kinds of communication technologies and PLC are interchangeable. The touch screen can automatically peel and other different weighing operations. For example, in the case of touch screen failure, intelligent weighing instruments can replace quantitative control, which meets the needs of mutual replacement functions.

(2) Digital DC speed regulator, frequency conversion controller, soft starter, switch components, etc. cooperate with stirring quantitative weighing control in the production process of the reaction kettle. The touch screen can fine-tune the stirring frequency conversion power, and the stirring motor rotates at a low speed, so that the liquid materials can be better mixed, and the properties of the materials will not be destroyed under high-speed stirring, which is suitable for low-speed frequency conversion mixing and mixing ingredients.

(3) The manual intervention is less and less, the operation points are more and more concentrated, and the operation mode is more and more software. The real-time displayed weight can be read at the batching site of the reaction container production while feeding, and the stirring power display is also in the same monitoring position, which is convenient to read different data at any time, saving the time of manual intervention, and the Batching system corrects errors by itself for artificially incorrect operation, thus solving errors in the process of incorrect feeding.

(4) The function of control system is becoming more and more comprehensive, and the role of CRT is becoming stronger and stronger. Control system and

The batching site can monitor the batching situation in different offices to improve the work efficiency of employees.

(5) The digital signal goes deeper and deeper into the field, and the control will be further dispersed. This program is mainly reflected in the application of digital weighing instruments and digital weighing sensors. The accuracy of on-site weighing control will not be affected by external mechanical structure. The digital integration technology is also comprehensively applied in the touch screen, which avoids the use space on site and simplifies the complex configuration of equipment.

(6) Information management technologies such as enterprise management information system (MIS) and enterprise resource planning (ERP) have been successfully applied in some advanced enterprises. The integration of enterprise management informationization and production process control is also developing rapidly, and e-commerce is also playing an increasingly important role in changing the operation and management mode of enterprises.
