基于S3C2410的井下WiFi便攜終端的設(shè)計

設(shè)計了基于WiFi技術(shù)的煤礦井下信息設(shè)備終端，利用WiFi無線局域網(wǎng)技術(shù)和VoIP語
音處理技術(shù)，通過采用嵌入式微處理器S3C2410和Linux操作系統(tǒng)作為軟件平臺可實現(xiàn)VoIP語音通話、人員定位和環(huán)境監(jiān)測等功能。各項功能都已經(jīng)通過試驗，通話時語音清晰，無明顯延遲，可以滿足井下生產(chǎn)應(yīng)用的需要。同時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.
