摘要
设计了基于WiFi技术的煤矿井下信息设备终端,利用WiFi无线局域网技术和VoIP语音处理技术,通过采用嵌入式微处理器S3C2410和Linux操作系统作为软件平台可实现VoIP语音通话、人员定位和环境监测等功能。各项功能都已经通过试验,通话时语音清晰,无明显延迟,可以满足井下生产应用的需要。同时终端还具有良好的可扩展性。
In view of the maintenance difficulty of tunnel information equipment that caused by disunity,a portable terminal based on WiFi technology was designed and can perform VoIP,human position,environment detection funciotn . The hardware circuit was designed by using ARM embedded microprocessor as the core;the access to WLAN was achieved by introducing WiFi module,the development of software was accomplished rely on Embedded Linux which served as platform.
