隨著光伏發(fā)電系統(tǒng)快速發(fā)展,以及電動(dòng)汽車充電樁的普及,傳統(tǒng)的剩余電流保護(hù)器無(wú)法滿足實(shí)際需求。介紹了一款B型剩余電流保護(hù)器,采用磁調(diào)制剩余電流互感器和零序電流互感器采集剩余電流。根據(jù)GB/T 22794—2017標(biāo)準(zhǔn)要求,可識(shí)別1 kHz及以下的正弦交流、帶和不帶直流分量的脈動(dòng)直流、平滑直流等剩余電流信號(hào)。經(jīng)信號(hào)調(diào)理電路將電壓信號(hào)送到單片機(jī)進(jìn)行采集和判斷。通過(guò)試驗(yàn)測(cè)試,該樣機(jī)在測(cè)試精度和速度上均符合國(guó)家標(biāo)準(zhǔn)的相關(guān)要求。The rapid development of photovoltaic power generation systems and the popularity of electric vehicle charging piles make the traditional residual current protective devices unable to meet the actual demand.This paper proposed a type B residual current protective device,which uses the magnetically modulated residual current transformer and the zero sequence current transformer to acquire the residual current.According to the requirements of GB/T 22794—2017,the type B residual current protective device can detect sinusoidal AC residual current of 1kHz and below 1kHz,pulsating DC residual current with and without DC component,smooth DC residual current and so on.The signal processing circuit sends the voltage signal to the MCU for acquisition and judgment.Through experimental tests,the device meets the relevant requirements of national standards in terms of test accuracy and speed.

便攜式B型超聲診斷儀具有無(wú)創(chuàng)傷、簡(jiǎn)便易行、相對(duì)價(jià)廉等優(yōu)勢(shì),在臨床中越來(lái)越得到廣泛的應(yīng)用。它將超聲波技術(shù)、微電子技術(shù)、計(jì)算機(jī)技術(shù)、機(jī)械設(shè)計(jì)與制造及生物醫(yī)學(xué)工程等技術(shù)融合在一起。開(kāi)展該課題的研究對(duì)提高臨床診斷能力和促進(jìn)我國(guó)醫(yī)療事業(yè)的發(fā)展具有重要的意義。 便攜式B型超聲診斷儀由人機(jī)交互系統(tǒng)、探頭、成像系統(tǒng)、顯示系統(tǒng)構(gòu)成。其基本工作過(guò)程是:首先人機(jī)交互系統(tǒng)接收到用戶通過(guò)鍵盤或鼠標(biāo)發(fā)出的命令,然后成像系統(tǒng)根據(jù)命令控制探頭發(fā)射超聲波,并對(duì)回波信號(hào)處理、合成圖像,最后通過(guò)顯示系統(tǒng)完成圖像的顯示。 成像系統(tǒng)作為便攜式B型超聲診斷儀的核心對(duì)圖像質(zhì)量有決定性影響,但以前研制的便攜式B型超聲診斷儀的成像系統(tǒng)在三個(gè)方面存在不足:第一、采用的是單片機(jī)控制步進(jìn)電機(jī),控制精度不高,導(dǎo)致成像系統(tǒng)采樣不精確;第二、采用的數(shù)字掃描變換算法太粗糙,影響超聲圖像的分辨率;第三、它的CPU多采用的是51系列單片機(jī),測(cè)量速度太慢,同時(shí)也不便于系統(tǒng)升級(jí)和擴(kuò)展。 針對(duì)以上不足,提出了基于FPGA的B型超聲成像系統(tǒng)解決方案,采用Altera公司的EP2C5Q208C8芯片實(shí)現(xiàn)了步進(jìn)電機(jī)步距角的細(xì)分,使電機(jī)旋轉(zhuǎn)更勻速,提高了采樣精度;提出并采用DSTI-ULA算法(Uniform Ladder Algorithm based on Double Sample and Trilinear Interotation)在FPGA內(nèi)實(shí)現(xiàn)數(shù)字掃描變換,提高了圖像分辨率;人機(jī)交互系統(tǒng)采用S3C2410-AL作為CPU,改善了測(cè)量速度和系統(tǒng)的擴(kuò)展性。 通過(guò)對(duì)系統(tǒng)硬件電路的設(shè)計(jì)、制作,軟件的編寫、調(diào)試,結(jié)果表明,本文所設(shè)計(jì)的便攜式B型超聲成像系統(tǒng)圖像分辨率高、測(cè)量速度快、體積小、操作方便。本文所設(shè)計(jì)的便攜式B型超聲診斷儀可在野外作業(yè)和搶險(xiǎn)(諸如地震、抗洪)中發(fā)揮作用,同時(shí)也可在鄉(xiāng)村診所中完成對(duì)相關(guān)疾病的診斷工作。
