摘要
设计出一种具有NB-IoT通信双网关的物联网智能燃气表,根据前置网关和后置网关的位置和连接方式不同分为4种方案,分析4种方案的燃气表功能结构和信息流转步骤。在智能燃气表中设置前置网关和后置网关,对传输数据的安全性、准确性实现了双重保证。
An IoT intelligent gas meter with NBIoT communication dual gateway has been designed.It is divided into four schemes according to the different positions and connection modes of front gateway and rear gateway,and the functional structure and information flow steps of gas meters in four schemes are analyzed.Setting the front gateway and the rear gateway in the intelligent gas meter can ensure the security and accuracy of the transmitted data.
