Research on 5G Networking in Multi Machine Cooperative Operation of Suburban Smart Farm

The research on the operation technology of a single agricultural machine gradually tends to be mature, and few research reports on the communication technology of joint operation of multiple agricultural machines are seen. During the operation of multiple agricultural machines, a large number of different types of data (images, videos, etc.) are continuously collected by on-board sensors. Whether 5G can meet the transmission requirements of these data on bandwidth, time delay, speed, etc. to realize the cooperative operation of machine groups is a scientific problem worth studying. After carefully combing the research status and dynamic analysis at home and abroad, it is proposed that wireless communication technology supporting multi machine cooperative operation is the key technical feature of the smart farm; It is worth studying whether the coverage and signal strength of 4G and 5G in the farm support multi machine cooperative operation. In this paper, a national agricultural science and technology farm in Xinxiang, Henan province is selected as the experimental base. Through the design of experiments, the received power of reference signals and the ratio of signal to interference and noise are tested. The coverage and intensity of 4G and 5G signals are measured by on-board instruments and hand-held instruments, and the measured data are plotted for visual display and analysis, so as to provide a scientific basis and guidance on how to use 4G and 5G hybrid networking.
