Feeding system real-time monitoring and database management (SCADA) and other upper computer application software, can save the product formula, reaction data, real-time data, etc., and can realize the historical data query, report printing, real-time data and status display, remote control and other functions, the two upper computer number of digging library can be effectively kept in sync. The main control program of PLC of the lower machine, as well as the communication, dosage precision control and dosage truck walking subroutine are designed.

The Batching system adopts a composite predictive control algorithm based on adaptive combined with PID, the algorithm combines the characteristics of adaptive control with wide-range and fast adjustment organically, and when the deviation of the system is larger than a certain set value, it adopts adaptive rule control combined with human experience, and when the deviation of the system is smaller than the set value, it adopts PID control, and the two inputs of the controller are the system expectation and deviation, and the different expectation values will predict the different deviation. different expectation values, different aerial fallout is predicted, and the effectiveness of the method is proved by experiments. The loading system adopts negative pressure Roots pump power source, the pipeline conveying pressure is low vacuum, the pipeline wind speed is about 10-35m/sec, and the material is in the form of mist in the pipeline. Negative pressure conveying starting point pressure is equal to or close to atmospheric pressure, the end point pressure between -10 to ~ 50Kpa, pipeline vacuum along the conveying pipeline gradually increased. Negative pressure rare-phase conveying system is also called vacuum rare-phase conveying system.

Feeding system is suitable for conveying, measuring and batching, with weighing and batching trolley, screw, belt as the material conveying tool, and at the same time dynamic weighing and batching control of the complete set of automation equipment. According to the user's specific production process requirements, through the human group configuration monitoring system and PLC program to load to the weighing and batching trolley material weight, flow control, so as to achieve accurate measurement and batching. As a dynamic continuous measuring and batching automatic control device, it can also provide accurate measuring data and control means for production control and management of various industrial sites.
