井下低功耗WiFi手持终端设计
Design of WiFi Handheld Terminal with Low-power Consumption
摘要
Abstract
In view of problems that traditional handheld terminal is difficult to communicate in coal mine and its standby time is short, a design scheme of handheld terminal with low-power consumption was proposed, and designs of hardware circuit and software of the handheld terminal were introduced. The handheld terminal uses PXA322 processor to finish collection and transmission of data of voice, image and video, programmable management of power supply circuit was designed for that WiFi network wastes electricity in searching on network. The experiment result showed that the handheld terminal has characteristic of reliable communication, low-power-consumption and long lifetime, which can satisfy with demand of underground production application.关键词
