摘　　要：为了实现低功耗和远距离兼具的数据传输,文中以NB-IoT为核心技术,设计了无连接数据传输系统。该系统以STM32L151C8T6为主控芯片,BC28模块作为通信模块,利用UDP协议将终端传感器模块采集的数据通过NB-IoT网络传输到阿里云平台,同时阿里云平台也可以将控制数据等信息发送到终端系统。经测试,该系统稳定、可靠地实现了终端数据上传及云平台数据下发的双向传输功能,可广泛应用于实际需求。In order to realize the data transmission with low power consumption and long distance,this paper designs a connectionless data transmission system with NB-IoT as the core technology.The system uses STM32L151C8T6 as the main control chip and BC28 as the communication module.The data collected by the terminal sensor module is transmitted to Alibaba cloud platform through NB-IoT network by UDP protocol.At the same time,Alibaba cloud platform can also send the control data and other information to the terminal system.After testing,the system stably and reliably realizes the two-way transmission function of terminal data upload and cloud platform data distribution,which can be widely used in actual needs.
