摘要
为了实现在电力传输线路中构建物联网络,使得用电设备能方便地通过电力线接入网络,设计出一种由通信平台、控制平台和感知平台组成的网络架构,将原有CSMA/CA协议中的请求发送/清除发送机制改换为确认帧机制,增加了链路报警提示帧。经过合理配用微处理器和通信专用芯片,完成电力线组网。测试表明,网络架构和协议符合在电力传输线路中传送物联网信息的需要。
In order to achieve the construction of internet of things in electric power transmission lines,to make the electrical equipment access networks conveniently through the power line and to change the present situation of how to deploy the cable,a network architecture is constructed with communication platform,control platform,and cognitive platform.In this architecture,the mechanism of Request To Send/Clear To Send previously used in CSMA/CA protocol is changed to Acknowledgement frame,and therefore a type of frame for alarming in link is added.Experimental testing shows that the network architecture and protocol can meet the need for transmitting information of Internet of things in a power transmission line.
