Design and Research of Agricultural Production System Based on OpenHarmony

With the development of science and technology, intelligent environmental monitoring system has been widely used in the agricultural field.In order to implement the updated iteration of this technology, we are now developing a complete agricultural production system based on OpenHarmony: We use the development board, Hi3861 as the core of perception layer in the system, together with the acquisition of real-time data; Using MQTT protocol and TCP/IP protocol as the communication protocols, the information transmitted by Hi3861 is received through WiFi and uploaded to HuaweiCloud, which realizes environmental data monitoring, terminal equipment controlling and data connectivity. The experimental results show that the system can correctly collect feedback data, and the terminal can also correctly respond and control related devices according to user operations, and once again shows the advantages of OpenHarmony operating system in IoT (Internet of Things).
