為了提高PCB板制作的效率,改變傳統(tǒng)的化學(xué)腐蝕制板工藝,使用機(jī)械仿形銑制作電路板的方法,設(shè)計(jì)了以ATMEGA16單片機(jī)為核心部件的PCB板雕刻機(jī)控制系統(tǒng)。其中包括PCB雕刻機(jī)的基本功能、主要硬件電路設(shè)計(jì)和軟件的實(shí)現(xiàn)流程,并給出了相關(guān)設(shè)計(jì)電路。重點(diǎn)分析了雕刻機(jī)步進(jìn)電機(jī)的驅(qū)動(dòng)電路以及主軸電機(jī)的驅(qū)...
便攜式信號(hào)采集在機(jī)器健康診斷系統(tǒng)中有較高的應(yīng)用價(jià)值。機(jī)器健康診斷的信號(hào)特點(diǎn)是包括低頻信號(hào)。本文研究是為了實(shí)現(xiàn)簡(jiǎn)易而且低成本的低頻便攜式信號(hào)采集。以Microchip公司單片機(jī)PIC18F1320為核心設(shè)計(jì)信號(hào)采集電路,實(shí)現(xiàn)了信號(hào)的采集和保存。系統(tǒng)采用串行電可擦除芯片24LC32A保存數(shù)據(jù),經(jīng)...
介紹了當(dāng)前普通標(biāo)記機(jī)控制系統(tǒng)現(xiàn)狀及其存在缺點(diǎn),給出氣動(dòng)標(biāo)記機(jī)及相頻修正PWM模式的工作原理。采用ATmega16單片機(jī)和USB轉(zhuǎn)換RS232接口器件CH341T實(shí)現(xiàn)驅(qū)動(dòng)控制系統(tǒng)與PC的實(shí)時(shí)通訊,標(biāo)記控制系統(tǒng)可升級(jí)到USB接口。采用基于ATmega16的相頻修正PWM替換555振蕩電路產(chǎn)生的PWM,可...
