Automatic batching compound fertilizer production system based on parallel bin structure

Fertilizers play a very important role in ensuring the continuous increase in production and income of crop producers. However, in the production process of compound fertilizers, due to the lag and external interference in the production process of fertilizer ingredients, problems with yield and quality can arise. Therefore, the accuracy of ingredients plays a crucial role in the production of compound fertilizers. This article focuses on the complex production process of compound fertilizers, using a parallel weighing bin structure to design a batching control scheme. The upper computer provides a relatively good and intuitive human–machine interface. By using WinCC software, real-time communication between the programmable logic controller system and the remote computer system can be achieved through the online network, thereby achieving effective monitoring and unified management of the entire system process, and achieving precise control of material distribution. Through the analysis of software and hardware, as well as the setting of on-site equipment, the composition of composite fertilizers was analyzed, indicating that this method has good application prospects as a batching control scheme.
