The intelligent grain storage and retrieval system adopts the 'one card' for management, including 9 links. Starting from the registration of grain transport vehicles entering the grain depot, the system can automatically obtain weighing scale data. Vehicle information and grain information can be displayed in real time at different stages through intelligent chip cards. One vehicle, one card, strict management, and each operator can only enter data from their own control stage. This not only constrains each other but also relates to each other, avoiding the occurrence of favoritism, corruption, and "favoritism" in the management mechanism.

　　The rapid grain collection and testing system is a fast chain modular system, consisting of an automatic sampling system and an automatic testing system. The system is centered on a controller and adopts a modular design, fully considering the various needs of grain collection. It can control the position of the sampling machine and the rotation angle of the sampling rod to accurately obtain data on impurities, moisture, bulk density, etc. of grain. The main features of this system are complete functionality, simple structure, clear panel, and easy operation. The integration of manual and automatic operation can greatly improve the efficiency of grain collection inspection and reduce grain collection costs.
