本文结合电力业务实际通信需求,提出了一种融合多种通信协议的5G物联网关设计。选用IPQ8072A作为主控芯片,支持5G、WiFi、以太网、HPLC、LoRa和串口等通信方式,不仅适用于视频监控、智能巡检等对性能敏感的宽带通信业务场景,还适用于采集、传感等对成本敏感的窄带通信业务场景。测试结果表明,5G网关与4G终端相比,大幅提升了传输速率,并且验证了轻量级安全加密认证功能。本设计功能接口丰富,实现了多数据通道并行传输,通过汇聚的方式化繁为简地实现了电力物联网“端-边-云”的通信链路,具有广泛的应用场景。

In the paper,a 5G IoT gateway design scheme that integrates multiple communication protocols is proposed combining with the actual communication requirements of the power business.The design selects IPQ8072A as the main control chip and supports 5G,WiFi,Ethernet,HPLC,LoRa,and serial port communication methods.It is not only suitable for performance-sensitive broadband communication business scenarios such as video surveillance and intelligent inspection,but also suitable for cost-sensitive narrowband communication business scenarios such as acquisition and sensing.The test results show that compared with 4G terminals,the 5G gateway has greatly increased the transmission rate and verified the lightweight security encryption and authentication function.This solution has rich functional interfaces,realizes the parallel transmission of multiple data channels,and realizes the “end-side-cloud” communication link of the power Internet of Things by means of convergence,which has a wide range of application scenarios.
