Abstract

With the development of agricultural technology, modern farms have higher and higher requirements for crop storage control system. The crop storage control system based on PLC is designed to improve the storage quality and efficiency of crops, and to reduce the probability of deterioration, decay and loss of agricultural products.

This design is committed to the development of a modern crop storage control system based on PLC to meet the needs of modern farms for efficient and intelligent storage management. The system is for 1,000 square meters of storage space, which can be intelligent storage control of more than three kinds of crops. It integrates crop status monitoring, environmental monitoring, intelligent warehouse monitoring, fault diagnosis and alarm, and man-machine interface and other functions. Through the selection and programming of major control equipment such as PLC and touch screen, the intelligent management of crops is realized, storage efficiency is improved and management costs are reduced. At the same time, the operation status of the device is monitored in real time. Once the abnormal situation is found, immediately alarm and diagnose the cause of the fault to ensure the stable operation of the system.
