Mugihe cyo gusudira kurigusudira ultrasonic, ibimenyetso byamashanyarazi byinjira muri sisitemu ya acoustic ihinduka vuba, kandi intera ihindagurika ni nini.Kugirango tunoze umuvuduko wo gupima nukuri, ubanza, hafatwa ingamba zo guhitamo chip hamwe nigisubizo cyihuse, kandi umwanya uhoraho wibigize hamwe nayunguruzo rwumuzunguruko wa peripheri yumuzingi wa chip bigenzurwa kuba munsi ya 0.2 ms. , kugirango rero tumenye neza igihe cyo gusubiza cya sisitemu kiri munsi ya ms 2, kandi uhuze icyifuzo cyo kumenya ibimenyetso byamashanyarazi bihinduka vuba.Kugirango hamenyekane ibisabwa byumurongo mugari wa amplitude hamwe nibiranga sisitemu, sisitemu yo kurwanya ubwoko bwa RCK ifite ubusobanuro buhanitse kandi ihamye iratoranijwe, ifite inducance nkeya ya parasitike na capacitance.Ibice bya Op-amp bizatoranywa hamwe no gukingura gukinguye kurenza 10 no gufunga-gufunga gukabije munsi ya 10. Muri ubu buryo, umurongo wa amplitude-frequency umurongo ushobora kuboneka kuva 0 ~ 20 kHz ± 3 kHz.Ibikurikira nigisobanuro kigufi cya buri module ikora.
1.1 Gupima Vrms ya voltage RMS
Ibikoresho byo kwipimisha byakozwe muriyi mpapuro birashobora gupima ibimenyetso bya voltage ya sinusoidal hamwe no kugoreka hamwe na RMS ya 0 ~ 1 000 V hamwe na 20 kHz ± 3 kHz.Iyinjiza rya voltage ryakuwe mubimenyetso, agaciro ka RMS gahindurwa kuri AC / DC, hanyuma bigahinduka muburyo bubiri busohoka.Umuyoboro umwe utangwa kuri 3-biti ya metero ya metero yumutwe kumutwe wimbere wikizamini, cyerekana neza RMS agaciro ka 0-1 000 V.Ibindi bisohora 0 ~ 10 V analog voltage signal binyuze mumwanya winyuma wikizamini cyo gushaka amakuru no gusesengura na mudasobwa.
Ikimenyetso cya voltage kirashobora gukururwa na voltage transformateur, sensor ya element ya sensor cyangwa igikoresho cyo guhindura amashanyarazi.Ubu buryo
Nubwo kwigunga ari byiza, bizatanga impamyabumenyi zitandukanye zo kugoreka imivurungano no guhinduranya icyiciro cya 20 kHz yerekana amashanyarazi, bigatuma bigora kwemeza neza niba gupima ingufu hamwe no gupima icyiciro cya Angle.Iyi ngingo UKORESHEJWE KUGARAGAZA KUBIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHWA BIKORESHEJWE ibimenyetso byerekana imbaraga za generator ya ultrasonic, generator ya ultrasonic ikora nta ngaruka igira.
AD637 ikoreshwa mugupima voltage RMS.Ni AC-DC RMS ihindura hamwe na hejuru ya upconversion yukuri hamwe na bande yagutse, kandi ihinduka ntirishobora guhinduka.Nukuri guhindura RMS.Ikosa ntarengwa ni 1%.Iyo ibintu byahindutse ari 1 ~ 2, ntakosa ryongeyeho.
1.2 Gupima agaciro keza
Inzira ya RMS yo gutahura yakozwe muriyi mpapuro irashobora kumenya ibimenyetso biriho hamwe no kugoreka sinusoidal ya 0 ~ 2 A, 20 kHz ± 3 kHz.Mugukurikiza urugero rusanzwe rwicyitegererezo rwahujwe murukurikirane rwumutwaro wa ultrasonic generator muri FIG.1, ikigezweho kibanza guhindurwa mubimenyetso bya voltage bihwanye nayo.Kubera ko icyitegererezo cyicyitegererezo ari igikoresho cyananiwe kurwanya, ntabwo kizana kugoreka imiyoboro ihindagurika cyangwa guhinduranya icyiciro, kugirango hamenyekane neza ibipimo.Ikimenyetso cya voltage ihwanye nubu ihindurwamo ibimenyetso bisa na voltage ya RMS AC-DC ihindura AD637, isohoka kuri metero ya metero ya mudasobwa na mudasobwa muburyo bubiri.Ihame ryo guhindura ni kimwe na RMS ya voltage ihinduka.
1.3 Gupima imbaraga zikora
Ikimenyetso gikomeye cyo gupima imbaraga kiva mubitereko bya voltage na I / V byahinduwe muburyo bwa RMS bwo gupima module ya voltage nubu.Intandaro yimbaraga zo gupima module ni AD534 igereranya igwiza kandi ikayungurura.Nyuma yumubyigano uhita ugwizwa nubu kugwiza kugezubu, ibice byinshi-byihuta byungururwa kugirango ubone imbaraga zifatika.
1. 4 Gupima itandukaniro ryicyiciro hagati yubu na voltage
Itandukaniro ryicyiciro hagati yinjiza voltage niyumuvuduko wa ultrasonic transducer bipimwa muguhindura voltage yinjiza nibimenyetso byubu mumiraba ya kwadarato ukoresheje igereranya rya zeru, hanyuma ugahuza itandukaniro ryicyiciro binyuze muri XOR itunganijwe.Kuberako nta tandukanyirizo ryicyiciro riri hagati yumubyigano numuyoboro gusa, ariko kandi hariho itandukaniro riri hagati yisasu no gutinda, Ming Yang yanashizeho uruziga rwigihe kugirango amenye icyerekezo nicyerekezo.Niba hari icyo ukeneye, twandikire.
1.5 Gupima inshuro
Module yo gupima inshuro imwe ifata chip microcomputer imwe imwe ya chip 8051, ikoresheje inshuro zisanzwe za kristu, kristu ya pulse yerekana ibimenyetso mugihe runaka, irashobora kugerwaho muri ms 1, inshuro ni 20 kHz, ikosa ntirirenga 2 Hz.Ibisubizo byo gupima inshuro bisohoka numubare wa 16-biti, kwinjiza mudasobwa ya I / O, hanyuma uhindurwe muburyo bwa decimal nyayo ya progaramu ya software.
Ultrasonic plastike yo gusudira irangiye mugihe gito nigitutu, kandi inzira yo gusudira yerekana ibiranga ibintu byihuse, bigoye, bigoye kandi nibintu byinshi.Mugihe na nyuma yo gusudira, guhangayikishwa cyane no guhindura ibintu (gusudira gusigara gusigara, gusudira kugabanuka, gusudira gusudira) bizabyara umusaruro, kandi guhangayika gukomeye hamwe no gusudira gusigara biterwa no gusudira, ariko bikagira ingaruka no guhindura imikorere yakazi hamwe nudusembwa two gusudira.
Iragira kandi ingaruka ku gusudira kwimiterere yimirimo nimbaraga zivunika zoroheje, imbaraga zumunaniro, imbaraga zitanga umusaruro, ibiranga kunyeganyega nibindi.Cyane cyane bigira ingaruka kubikorwa byo gusudira bikora neza kandi bigahinduka.Ikibazo cyo gusudira ubushyuhe bwumuriro no guhindura ibintu biragoye cyane, utabanje kureba kure, ntushobora guhanura byimazeyo no gusesengura ingaruka zo gusudira kumiterere yubukanishi bwabasuderi bose, kandi ugasuzuma neza ubuziranenge bwo gusudira.Mugihe kimwe, amakuru menshi yingenzi, arizo ngaruka, ntashobora gupimwa muburyo busanzwe.
Turi abanyamwuga R & D, umusaruro, no kugurisha kwaimashini yo gusudira ultrasonic, imashini yo gusudira cyane, imashini yo gusudira ibyuma, Imashini itanga amashanyaraziuruganda.Twishimiye gusangira inkunga ya tekinike ya ultrasound hamwe nuburambe bwa ultrasound.Niba ufite umushinga wo kugisha inama, nyamuneka tubwire ibikoresho nubunini bwibicuruzwa byawe.Tuzaguha gahunda ya ultrasonic yo gusudira kubuntu.
