摘要
介绍智能燃气表无线通信技术的现状,分析Lo Ra通信技术的特点、原理、网络结构,指出Lo Ra通信技术应用在智能燃气表的特点。Lo Ra通信技术传输距离远,功耗小,是一种有效的通信方式,但传输速率低,实时性差,有待进一步改进。
The current status of wireless com- munication technology for smart gas meter is intro- duced. The features, principle and network structure of LoRa communication technology are analyzed. The characteristics of LoRa communication technology that has been applied to smart gas meter are presented. The LoRa communication technology is an effective commu- nication mode due to its long transmission distance and small power consumption, but it needs further improve- ment due to its low transmission rate and poor realtime.
