Bing is a point-to-point bandwidth measurement tool (hence the b ), based on ping. Bing determines the real (raw, as opposed to available or average) throughput on a link by measuring ICMP echo requests roundtrip times for different packet sizes for each end of the link

water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a main line". In -10~+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.

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。其基本工作過程是:首先人機(jī)交互系統(tǒng)接收到用戶通過鍵盤或鼠標(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。
