摘要:在数字乡村建设中，为解决分布广、数量多的乡村生产设施监测数据集成效率低的问题，本文设计研发了一种基于物联网的乡村生产设施数字孪生管控技术并投入了使用。该技术使用MODBUS-RTU（Remote Terminal Units）协议采集各种生产设施监测数据；采用了MQTT(Message Queuing Telemetry Transport)和实时流数据处理技术，解决监测数据传输不稳定的问题；应用了NFC技术，解决传感器与模型自动关联问题，快速构建生产设施数字孪生模型。应用表明，本方法操作简单，可减少90%的数据映射工作量，且数据的稳定性和时效性高，为生产设施远程、智慧化管控奠定了基础。

Abstract: To promote rural digital construction and deal with slow integration and low efficiency of monitoring data of rural production facilities, MODBUS-RTU protocol is used in this paper to collect monitoring data of different types of production facilities based on modern information technology. Regarding to the unstable and untimely data transmission in rural area, the paper also adopts MQTT combined with real-time stream data processing technology, which greatly improves the stability and timeliness of data. What's more, to simplify the operation of the system, NFC technology is applied so that ordinary villagers can skillfully use it after simple training. The application results show that after the adoption of the digital twin management and control system, the workload has been reduced by 90%. Moreover, the data is stable and timely and the system is easy to operate. The method proposed in the paper is important to digital rural construction and it also provides a reference for subsequent improvement and development.
