摘要

在对AIRMAX网桥设备调试安装时

为了快速进行天线波束对准和IP地址联通测试

必须要及时准确获得网桥信号接收强度和信噪比等多种实时参数。设计了一款简易而低成本的网桥天线调试仪

使用ENC28J60以太网控制器实现调试仪与网桥的Telnet连接;利用ATMEGA328处理器完成信息的提取与筛选;通过LCD1602液晶显示屏显示网桥状态参数。实验结果表明:本系统的启动时间小于1 min

每隔2 s对所需参数进行更新并显示。达到调试工作对调试仪小型、快速、准确的要求。

Abstract

In order to quickly test the antenna beam alignment and Unicom IP address in installing the AIRMAX bridge debugging equipment

the bridge receiving signal strength

the signal-to-noise ratio

and other parameters in real time must be accurately measured. A low cost and simple bridge antenna instrument was designed using an ENC28J60 Ethernet controller to set up bridge Telnet connection to measure these parameters. Additionally

an ATMEGA328 processor was used to carry out information extraction and selection. The bridge parameter statuses were shown on an LCD1602 display. Experimental results show that this system's start time is less than 1 min

and it extracts and displays the Bridges RSSI and the NOISE value in every 0.5 s

satisfying the requirements of small

rapid and accurate debugging.
