摘要
提出了一种输电导线温度智能传感器的设计方法,该传感器由温度采集单元和无线适配单元组成,对外提供标准SDI-12通信协议的RS-485接口,温度采集单元与无线适配单元间采用433MHz的ISM频段进行无线通信,具有通信距离远的特点。
A design of smart temperature sensor on transmission line is proposed.The sensor is formed with temperature sensor units and wireless adapter modules,which provide external RS-485 interface with standard SDI-12 communication protocol.The wireless communication between temperature acquisition unit and wireless adapter unit used industrial scientific medical（ISM） band at 433 MHz,which have the characteristic of distance communication.
