設(shè)計(jì)了基于WiFi技術(shù)的煤礦井下信息設(shè)備終端，利用WiFi無(wú)線局域網(wǎng)技術(shù)和VoIP語(yǔ)
音處理技術(shù)，通過(guò)采用嵌入式微處理器S3C2410和Linux操作系統(tǒng)作為軟件平臺(tái)可實(shí)現(xiàn)VoIP語(yǔ)音通話、人員定位和環(huán)境監(jiān)測(cè)等功能。各項(xiàng)功能都已經(jīng)通過(guò)試驗(yàn)，通話時(shí)語(yǔ)音清晰，無(wú)明顯延遲，可以滿足井下生產(chǎn)應(yīng)用的需要。同時(shí)終端還具有良好的可擴(kuò)展性。

Abstract: 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.
