摘要 针对现如今农业领域灌溉系统在其灌溉区域进行实时数据采集中出现数据中断或丢包的问题,提出了基于双5G频段的先进技术在本地、远程以及中远距离的实时数据采集策略。首先规定采集终端与主控制器之间的通讯规约和握手准则,在现有自控技术的基础上采用中继放大技术对信号的失真率加以纠正,通过传统的通信技术完成数据的加密工作,保证数据的安全性。其次借助5G网关和内网穿透的DTU实现主控制器与远程IO采集器之间的无缝连接,最后通过实际信号强度测试得出该方法的正确性与有效性。 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.
