基于WiFi技术的井下多功能便携终端的设计与实现

Design of a Kind of Multifunction Portable Terminal Used in Underground Based on WiFi Technology and Its Implementation

针对井下信息设备各成体系、维护困难的问题,设计了一款基于WiFi技术的多功能便携终端。该多功能便携终端采用WiFi模块实现无线局域网的接入,其硬件电路以ARM嵌入式微处理器为核心,应用软件以嵌入式Linux为平台,可实现VoIP语音通话、人员定位、环境监测等多种功能。

In view of the problems that underground information equipments are self-governed and difficult in maintenance, a kind of multifunction portable terminal based on WiFi was designed. The multifunction portable terminal used WiFi module to realize connecting with wireless local network, its hardware circuit used ARM embedded microprocessor as core, and its application software used embedded Linux as platform. It could perform functions of VoIP, positioning for personnel and monitoring for environment.
