Intelligent Operation and Maintenance System of Grain Combine Harvester Based on STM32 and Onenet Platform

When the grain combine harvester is running in the field, it is easy for the corn harvester to fail due to the different density of crops, uneven roads, complex external environment, etc., so it is particularly important to monitor the components of the corn harvester. This paper designs an intelligent operation and maintenance system of grain combine based on STM32 and Onenet platform, which takes STM32 as the monitoring core and realizes real-time monitoring of grain combine operating parameters.fault diagnosis and data during operation are uploaded to Onenet platform and controlled by STM32 to ensure the stable operation of grain combine. It also facilitates the driver to know the operation state of the grain combine through the screen, facilitates remote monitoring and improves the level of intelligence.
