In order to solve the problem of data interruption or packet loss in the real-time data collection in the irrigation area of the irrigation system in the agricultural field,a real-time data collection strategy based on advanced technology of dual 5G frequency bands in local,remote and medium and long distances was proposed.Firstly,the communication protocol and handshake criterion between the acquisition terminal and the main controller are stipulated,and the relay amplification technology is used to correct the distortion rate of the signal on the basis of the existing automatic control technology,and the data encryption work is completed through the traditional communication technology to ensure the security of the data.Secondly,with the help of 5G gateway and intranet-penetrating DTU,the seamless connection between the main controller and the remote IO collector is realized.Finally,the correctness and effectiveness of the method are obtained by the actual signal strength test.
