Design of Embedded Monitoring System for Large-Scale Grain Granary

The scientific and effective storage of grain has a very important significance for the country. On the basis of analyzing the present situation of the traditional granary monitoring technology, a new network embedded granary monitoring system is designed based on STM32F103C8T6 processor and CAN bus, combining with the actual functional requirements of large-scale granary monitoring. The proposed granary monitoring system realizes real-time data transmission and monitoring of the environmental parameters such as temperature, humidity, and grain reserves. The hardware circuit of each module of the lower computer is given. And the driver program of the lower computer is developed. In the host computer part, the monitoring interface of the remote host computer is designed on PC. Meanwhile, the proposed granary monitoring system has the function of alarm and prompts. The test results show that the embedded granary monitoring system has good stability and reliability. The new monitoring system for large-scale granary based on STM32 processor can monitor the current grain situation more accurately and quickly.
