基于AR2524芯片的矿用摄像仪无线网络接口设计

摘要

In view of demand that some mine field is unconvenient for cable laying and need video transmission by wireless, wireless network interface of camera based on AR2524 chip was designed on platform of network camera. The wireless network interface uses IEEE802.11b/g protocol and can access Ethernet by wireless AP. The experiment result showed that the wireless network interface can realize wireless connection with wireless monitoring and control substation and transmit video signals, and has long transmission distance, clear image, smooth video, which meets with basic demands of mine video transmission.%针对部分煤矿现场有线敷设不方便、需要通过无线传输视频的需求,在网络摄像仪的平台上,基于AR2524芯片设计了摄像仪的无线网络接口.该无线网络接口采用基于IEEE802.11b/g标准的传输协议,可通过矿用无线AP接入局域网中.测试结果表明,该无线网络接口能与无线监控分站实现无线连接并传输视频信号,传输距离远,图像清晰,视频流畅,满足了矿用视频传输的基本需求.
