NB-IoT通信技术在智能燃气表的应用

Application of NB-IoT Communication Technology to Smart Gas Meter

阐述智能燃气表无线通信技术的发展现状,分析NB-IoT通信技术应用在智能燃气表中的特点,指出应用NB-IoT通信技术的智能燃气表存在的问题(缺少必要的交易鉴权机制、缺乏燃气数据专业处理能力、技术成熟度不够)。智能燃气表通过内置网关解决了上述问题。指明内置网关的智能燃气表结构及网关的结构及功能。内置网关具有信息安全保护功能,能够进行通信鉴权和交易鉴权,具有专业的燃气数据处理能力,能够保证智能燃气表应用程序的升级与电信运营商网络升级的同步。探讨智能燃气表与燃气公司服务器的信息交互流程。

The development status of wireless communication technology for smart gas meter is explained. The characteristics of NB-IoT communication technology applied in smart gas meter are analyzed. It is pointed out that the existing problems of smart gas meter using NB-IoT communication technology (lack of necessary transaction authentication mechanism,lack of professional processing capability of gas data and insufficient technical maturity). The above-mentioned problems are solved through the built-in gateway in the smart gas meter. The structure of the smart gas meter with the built-in gateway and the structure and function of the gateway are indicated. The built-in gateway has information security protection function,can perform communication authentication and transaction authentication. It has professional gas data processing capability,which can ensure the synchronization of the upgrade of smart gas meter application program with the upgrade of the telecom operator network. The information exchange process between smart gas meter and gas company server is discussed.
