摘　　要：本文为在广播电视发射台站实现硬馈等温度监测,开发了一种基于Linux嵌入式的物联网测温系统。温度监测系统分为测温服务器、测温网关、测温节点三部分。低功耗的测温节点采用电池供电,测温网关采用POE供电,经实地测试运行表明该系统满足设计要求,实现了一种远距离,广覆盖的广电物联网应用[1]。This paper develops a temperature measurement system of Internet of Things based on Linux embedded to realize temperature monitoring such as hard feed in radio and television transmitting stations. Temperature measurement system is divided into three parts, which are temperature measurement server, temperature measurement gateway and temperature measurement node. Low-power temperature measurement node is powered by battery, and gateway is powered by POE. Test shows that the system meets design requirements and realizes a long-distance, wide-coverage radio and television Internet of Things application.
