摘要
在数字经济发展的浪潮中,窄带物联网(NB-IoT)等物联网(IoT)技术在燃气行业的应用较为广泛,但普遍存在兼容性问题。如果物联网终端通信平台要兼容不同厂家、不同类型、不同协议的燃气设备,并监控不同数据点、处理不同业务需求,其难度非常大,尤其要兼容将来的新增设备更是难上加难。为了减少系统二次开发,节约人力、财力、物力,对物联网系统框架进行了研究,设计了物联网应用控制平台、物联网终端通信平台和物联网终端设备三级新型框架。在某集团公司物联网系统中,采用独特的数据传输格式,对不同设备、不同协议、不同业务、不同加密算法进行无差别化数据编组,采用统一格式减少数据交互次数,解决了系统对不同设备的兼容性、安全性和数据传输效率问题,实现了物联网通信的安全、可靠、灵活、高效。该研究有助于燃气行业的信息化、数字化发展。
In the wave of digital economy development,narrow band Internet of Things(NB-IoT)and other Internet of Things(IoT)technologies are more widely used in the gas industry,but there is a general compatibility problem.If the IoT terminal communication platform must be compatible with different manufacturers,different types and protocols of gas equipment,and monitor different data points and handle different business needs,it is very difficult,especially to be compatible with new devices in the future.To reduce the secondary development of the system and save human,financial and material resources,the framework of the IoT system is studied and a new three-level framework of IoT application control platform,IoT terminal communication platform and IoT terminal equipment is designed.In a group company’s IoT system,a unique data transmission format is used to group data without differentiation for different devices,different protocols,different services and different encryption algorithms,and a unified format is used to reduce the number of data interactions,which solves the compatibility,security,and data transmission efficiency problems of the system for different devices and realizes the safety,reliability,flexibility,and efficiency of IoT communication.This research contributes to the development of informationization and digitization in the gas industry.
