摘　　要：近两年我国已基本全面形成了以5.8G频点为基础的ETC系统,然而该系统较少考虑到无线电干扰问题。本文分析了可能发生的无线电干扰情况,并设计了一套基于物联网技术的5.8G无线电干扰定位系统。当ETC系统出现问题时,能够帮助高速公路管理人员快速了解周边环境中ETC频段射频信号的分布情况,并对无线电空间中的干扰源进行初步定位分析,尽快排除无线电干扰问题。In the past two years,China has basically formed an ETC system based on 5.8G frequency,but this system takes less con⁃sideration of radio interference issues.This article analyzes the possible radio interference situation and designs a 5.8G radio inter⁃ference location system based on the Internet of Things technology.When there is a problem with the ETC system,it can help high⁃way managers quickly understand the distribution of RF signals at ETC band in the surrounding environment,and conduct a pre⁃liminary analysis of interference sources in the radio space to eliminate radio interference problems as soon as possible.
