Ukuqapha esizindeni sesikhathi nge-RMS namanani aphezulu (bona Isahluko 5)

Ukuqapha esizindeni samafrikhwensi ngamavelu omkhawulo ancike kwi-frequency-band (bona Isahluko 6)

Khetha imodi ngaphansi kokuthi "Ukuqapha". Imodi esanda kukhethwa kanye nemikhawulo ehambisanayo izohlala isebenza ngemva kokuvala uhlelo noma ukuphazamisa uxhumano lwe-USB. Okufanayo kusebenza kumsebenzi wokufundisa (bheka. Isahluko 7).

4.2.3. Inzuzo
Inzuzo ingakhethwa kumanani 1, 10 kanye ne-100 ngemenyu ethi "Lungisa". Isilungiselelo esithi "Okuzenzakalelayo" sikhetha ngokuzenzakalelayo ububanzi bokuzuza obufaneleke kakhulu. Kulokhu imenyu yenzuzo iba mpunga.
Imisebenzi eminingi yokuqapha ingenziwa kusetshenziswa inzuzo ezenzakalelayo (auto). I-advantageous ngoba ifinyelela ukulungiswa okungcono uma ikala ukudlidliza okuphansi amplitudes emazingeni aphezulu okuzuza. Ngakolunye uhlangothi ukuphakama okungalindelekile ampama-litudes awabangeli ukugcwala ngokweqile.
Kukhona, nokho, izinhlelo zokusebenza lapho ukukhethwa kokuzuza okuzenzakalelayo okungafanelekile, ngokwesiboneloample, kwe ampama-litudes ahlala eguquguquka azungeze indawo yokushintsha noma ukushaqeka okukodwa.

4.2.4. Izihlungi nezihlanganisi
I-VS11/12 ingaqapha ukusheshisa kokudlidliza noma isivinini sokudlidliza. Uhlu lwezihlungi eziphakeme neziphansi ziyatholakala ukuze uzikhethe. Ibanga lefrikhwensi elibanzi kakhulu lingu-0.1 Hz ukuya ku-10 kHz ngokusheshisa, kanye no-2 kuya ku-1000 Hz ngesivinini. Ububanzi befrikhwensi bulungiswa ngemenyu yokudonsela phansi. Amabanga amathathu esivinini sokudlidliza angatholakala ekupheleni kwemenyu. Ukuze uthole ulwazi ngobubanzi befrikhwensi evamile ekuqapheni imishini ezungezisayo, bona Isahluko 9.
Ukusetha izihlungi nezihlanganisi kusebenza kuphela uma uqapha esizindeni sesikhathi (i-RMS nenani eliphakeme). Kumodi ye-FFT bayenziwa bangasebenzi.
4.2.5. Imikhawulo Yesexwayiso Ne-alamu
Ungakhetha inani lokuqapha kumenyu ethi “RMS/Peak”. Amanani e-RMS ngokuvamile asetshenziselwa ukulinganisa ukudlidliza, namanani aphezulu omthelela owodwa.
Umkhawulo we-alamu unquma umkhawulo wokushintsha kokuphumayo kwe-relay. Ifakwe ku-m/s² ukuze isheshiswe noma mm/s ngesivinini. Ibanga lenani elivumelekile lingu-0.1 kuye ku-500.0.
Umkhawulo wesixwayiso ufakwe njengephesentitage yenani le-alamu.
Amanani asuka ku-10 kuye ku-99% avumelekile. Umkhawulo oyisixwayiso ungasetshenziswa ukukhombisa isimo sangaphambi kwe-alamu ngama-LED ngaphambi kokuthi i-alamu icushwe (bona Isahluko 4.3).
I-“teach-in-factor” umsebenzi wokulinganisa ozenzakalelayo womkhawulo we-alamu (bona Isahluko 7). Inquma ukuthi umkhawulo we-alamu usethwe kude kangakanani ngaphezu kwenani eliphakeme elikalwa njengamanje. Umkhawulo wesexwayiso sokufundisa ngaso sonke isikhathi ubekwe ku-50%.
Kudingeka kuphela ukusetha kusengaphambili okuguquguqukayo kokuqapha kanye nomkhawulo we-alamu lapho ukala esizindeni sesikhathi (i-RMS nenani eliphakeme). Kwimodi ye-FFT umkhawulo we-alamu usethwe efasiteleni le-FFT (bona Isahluko 6).
4.2.6. Ishintsha okukhiphayo
I-VS11/12 iqukethe iswishi ye-PhotoMOS edluliselwe. Umsebenzi wokushintsha ungacaciswa kumenyu yezinketho. I-relay iyavula (nc) noma ivale (cha) ngokuphendula isixwayiso noma isignali ye-alamu.
Ukubambezeleka kokukhanyisa ukubambezeleka phakathi kokuvula amandla nokwenza kusebenze umsebenzi wokuqapha. Isiza ukuvimbela amasignali ama-alamu amanga ngemva kokuvula idivayisi okubangelwa ukusabela kwesikhashana kokucutshungulwa kwesignali.
Ibanga lokulibaziseka liyimizuzwana engu-0 kuye ku-99.
Ukubambezeleka kokukhanyisa ukubambezeleka phakathi komkhawulo we-alamu oweqiwe kanye nokushintshwa kwe-relay. Kuziro i-relay isabela ngokushesha.
Uma ubude besikhathi obuncane kufanele busebenze ekudluleni umkhawulo we-alamu, ukulibaziseka kokushintsha okungafika kumasekhondi angu-99 kungafakwa.
"Isikhathi sokubamba" yisikhathi lapho i- ampi-litude iwela ngaphansi komkhawulo we-alamu kuze kube i-relay ibuyela esimweni esivamile. Lesi silungiselelo singaba usizo uma kudingeka ubude besikhathi obuncane besexwayiso. Ububanzi busuka kumasekhondi angu-0 kuye kwangu-9.

4.2.7. Izilungiselelo / Ukulinganisa Kwefekthri
Ngokuchofoza inkinobho ethi “Setha okuzenzakalelayo” wonke amapharamitha abuyiselwa kuzilungiselelo zefekthri (ukusheshisa okungu-2-1000 Hz, ukuzuza okuzenzakalelayo, inani lomkhawulo elingu-10 m/s², i-alamu yangaphambili iye ku-50%, i-teatainin factor 2, i-relay ivala uma i-alamu icushiwe, ukushintsha ukubambezeleka 10 s, alarm ukubambezeleka 0 s, ukubamba isikhathi 2 s).
Iphasiwedi yokulinganisa (“I-Cal. Iphasiwedi”) idinga kuphela ukufakwa ngamalebhu okulinganisa.

4.3. Izinkomba zesimo se-LED
I-VS11 ikhombisa isimo samanje ngama-LED amane aluhlaza/abomvu. Noma nini lapho idivayisi isilungele ukusebenza wonke ama-LED akhanya. Ama-LED anokucushwa okulandelayo:
4 x eluhlaza: asikho isixwayiso / akukho alamu
2 x okuluhlaza/ 2 x okubomvu: umkhawulo wesixwayiso weqiwe
4 x okubomvu: umkhawulo we-alamu weqiwe
Ama-LED abonisa ileveli yamanje yokudlidliza ngokuhlobene namanani omkhawulo.
Angase ahluke esimweni samanje sokushintshwa uma ukulibaziseka kokushintsha noma isikhathi sokubamba singakadluli.

Ukulinganisa Kusizinda Sesikhathi

Ngaphandle kokuqapha kokudlidliza okuphumayo, i-VS12 ingasetshenziswa ngokuhambisana nesofthiwe ye-PC ukuze urekhode futhi ubonise i-RMS kanye namanani aphezulu ngokukhethiwe. filer kanye nezilungiselelo zokuhlanganisa.
Ngale njongo shintshela kuthebhu ethi “RMS/Peak”. Iwindi eliphezulu liqukethe isibonisi sezinombolo se-RMS ne-peak. Ishadi lesikhathi lihlela isikhathi senani lokudlidliza elikhethwe ngaphansi kokuthi “Isakhiwo” (Umfanekiso 4).Ilebula ye-axis yenani ibonisa ubuningi bokudlidliza kanye nesihlungi esikhethiwe. I-eksisi yesikhathi ilungisa ubude besikhathi sokurekhoda. Ngokuchofoza kwesokudla endaweni yeshadi (I-Fig – ure 5) ungakwazi ukukala ishadi ngokuzenzakalelayo (i-auto-scaling X/Y). Ngaphezu kwalokho ungakhetha imodi yokuvuselela (Umfanekiso 6).

Ishadi le-strip: idatha iboniswa ngokuqhubekayo ukusuka kwesokunxele kuye kwesokudla. Ishadi lomugqa lifana nerekhoda yeshadi (Y/t rekhoda).

Ishadi lobubanzi: libonisa isignali (isb. impulse) ngezikhathi ezithile ukusuka kwesokunxele kuye kwesokudla. Inani ngalinye elisha lengezwe kwesokudla kwelandulelayo. Uma igrafu ifika onqenqemeni lwesokudla lwendawo yesibonisi iyasulwa futhi idwetshwe kabusha ukusuka kwesokunxele kuye kwesokudla.
Isibonisi sifana naleso se-oscilloscope.
Shanela ishadi: lifana neshadi lescope ngaphandle kokuthi idatha endala ngakwesokudla ihlukaniswa umugqa oqondile osuka kudatha entsha kwesokunxele. Uma isakhiwo sifika onqenqemeni olungakwesokudla lwendawo yesibonisi asisuswa kodwa siyaqhubeka nokusebenza. Ishadi lokushanela lifana nesibonisi se-ECG.

Izindlela ezintathu zokubuyekeza zithinta kuphela isikhawu sesikhathi esibonakalayo seshadi. Yonke idatha elinganisiwe kusukela ekuvuleni iwindi, okuhlanganisa idatha engabonakali, isafinyeleleka. Kuya view idatha isebenzisa ibha yokuskrola engezansi kweshadi.
Izindlela ezintathu zokubuyekeza zisebenza kuphela uma "Ukukala okuzenzakalelayo" kuyekiwe ukukhethwa (Umfanekiso 5).
Izimbazo zeshadi zingalinganiswa kabusha ngokwenza ngokuchofoza kabili kunani lenombolo yelebula yezimbazo kanye nokubhala ngaphezulu inani.
Ngaphansi kokuthi "Khipha" uzothola izinketho ezilandelayo:

Kopisha idatha yeshadi njengethebula lenani ebhodini lokunamathisela

Kopisha igrafu yeshadi ebhodini lokunamathisela
Vula idatha yeshadi kuthebula le-Excel (uma i-Excel ifakiwe)

Lezi zinketho zokuthumela zingatholakala futhi njengezinkinobho eduze kweshadi.
Cindezela inkinobho ethi “Misa” uma ufisa ukukhansela ukurekhoda. Isibonisi sizophumula.
Ngokucindezela okuthi “Qalisa kabusha” ishadi liyasuswa futhi liqala kabusha.

Ukulinganisa ku-Frequency Range (FFT)

Ngaphezu kokuqapha i-RMS nenani eliphakeme, i-VS11 ne-VS12 inika amandla ukuqapha inani lomkhawulo ebangeni lefrikhwensi ngokusebenzisa ukuhlaziya (FFT). I-spectra yokudlidliza ingaba viewed ngokuhlanganyela nesofthiwe ye-PC.
Ukuze wenze lokhu, shintshela kuthebhu ethi "FFT". Iwindi (Umfanekiso 7) libonisa i-spectrum yemvamisa yenani eliphakeme lokusheshisa, elikhetheka ukusuka ku-5 kuye ku-1000 Hz noma ku-50 kuye ku-10000 Hz.Imodi yemvilophu iyatholakala kumadivayisi enguqulo xxx.005 nangaphezulu. Ukuze uyinike amandla, khetha into ethi “ENV” ngaphansi kokuthi “Ububanzi befrikhwensi”.
Ngoguquko olujwayelekile lwe-Fourier (FFT), cishe akunakwenzeka ukukhipha ama-pulses abuthakathaka uma kuqhathaniswa ne-spectrum yokudlidliza ye-roller bear. Ukuhlaziya imvilophu kuyithuluzi eliwusizo lale njongo. Ngokulungiswa okuphezulu okusheshayo, ijika lemvilophu yesiginali yokusheshisa iyatholakala (Umfanekiso 8)Ijika lemvilophu libe selibhekana noguquko lweFourier (FFT). Umphumela uwukumelelwa kwe-spectral lapho ama-rollover frequencies avela khona ngokucacile.
Irola elingalimele livame ukuba nokugqamayo kuphela ampi-litude kufrikhwensi yokujikeleza ku-spectrum yemvilophu. Uma kwenzeka umonakalo, ama-rollover frequencies abonakala njengamafrikhwensi ayisisekelo. I ampama-litudes ayanda ngomonakalo okhulayo. Umfanekiso 9 ubonisa ukuvezwa kwe-spectrum yemvilophu. Ngokuchofoza kwesokudla endaweni yeshadi ungakwazi ukukala ishadi ngokuzenzakalelayo (ukukala okungu-Y okuzenzakalelayo). Ukuchofoza kabili kulebula yesikali ye-Y-eksisi kukuvumela ukuthi ukale kabusha i-eksisi ngokuyibhala ngaphezulu.
Ukukala i-frequency axis (X) akudingekile ngenxa yokuthi kunqunywa ububanzi befrikhwensi ye-FFT (1/10 kHz). I-axis ye-Y ingaboniswa ngesikali somugqa noma se-logarithmic. Ukukhipha idatha yeshadi izinketho ezifanayo njengasezilinganisweni zesizinda sesikhathi ziyatholakala (bona Isigaba 9).
Izinkambu zokufaka ezingu-10 ampama-litudes namafrikhwensi ayi-10 atholakala ngaphansi kwemenyu yeshadi. Lapha ungacacisa umugqa womkhawulo ofakwa ku-spectrum yefrikhwensi bese ubonisa i-alamu lapho umkhawulo weqiwe. Umugqa womkhawulo ukuvumela ukuthi ukhethe ngokukhetha izingxenye ze-spectral.
Lokhu kungase kube i-advantageous ukuze kuqashwe ingxenye ethile phakathi kwenhlanganisela yamafrikhwensi okudlidliza.
Ngemodi yokushintsha, umkhawulo wesexwayiso nesikhathi sokulibaziseka izilungiselelo ezichazwe ezigabeni 4.2.5 no-4.2.6 ziyasebenza.
Emgqeni onamafrikhwensi angu-10 ungafaka noma yiliphi inani olifisayo kububanzi obungu-1 Hz ukuya ku-1000 noma u-10000 Hz (kuye ngebanga lesihlungi elikhethiwe). Umbandela kuphela ukuthi ama-frequency akhuphuka esuka kwesokunxele aye kwesokudla. I ampi-litude efakwe ngaphansi kwe-frequency ku-m/s² ingumkhawulo wefrikhwensi elandelayo ephansi kuze kufike kule frequency. Uma udinga amapharamitha ayisisekelo angaphansi kwe-10 ungaphinda ufake imvamisa ephezulu engu-1000 noma engu-10000 Hz ngokuhambisanayo. ampumkhawulo wokufunda ngokuya kwesokunxele.
Kulesi simo amanani angakwesokudla se-frequency ephezulu azozitshwa.
Ijika elilinganiselwe lingaboniswa noma lifihlwe eshadini. Ukuqapha komkhawulo we-VS11/12 nokho kuhlale kusebenza.

Umsebenzi Wokufundisa

I-VS11 inomsebenzi wokufundisa wokulinganisa umkhawulo we-alamu. I-PC ayidingeki kulo msebenzi. Ukuze usebenzise umsebenzi wokufundisa inswitshi yokudlidliza kufanele igxunyekwe entweni ezokalwa, okufanele ibe sesimweni soku- linda ukuqapha ukusebenza.
Ukuze uvule umsebenzi wokufundisa susa ikhava yesikulufu esibhalwe ukuthi “fundisa-ngaphakathi” bese ucindezela kafushane inkinobho engaphansi ngento ende, engabambisi. Lapho wenza lokhu qaphela ukugwema imithelela ku-casing.
Ngokwemodi yokuqapha ekhethiwe, iswishi yokudlidliza manje izonquma umkhawulo we-alamu ngokusekelwe kumanani atholakalayo.
Lokhu kungathatha amasekhondi angu-4 kuya kwangu-40, lapho ama-LED ahlala engakhanyi. Okwamanje izinqubo ezilandelayo zizosebenza ekushintsheni kokudlidliza:

Nge-RMS nokuqapha okuphezulu esizindeni sesikhathi ubuningi bokuqapha obukhethiwe ngebanga lokuhlunga elimisiwe likalwa imizuzwana embalwa. I-RMS ewumphumela kanye namanani aphezulu aphindaphindwa into yokufundisa (ehlelwe ngaphansi kokusetha) futhi alondolozwe njengomkhawulo we-alamu. Umkhawulo wokuxwayisa ubekwe ku-50%.
Ngaphambi kokwenza kusebenze umsebenzi wokufundisa sicela ukhethe ibanga lesihlungi elifanelekile.

Ngokuqapha kwe-FFT esizindeni samafrikhwensi i-spectrum ye-frequency efika ku-10 kHz iyalinganiswa futhi ilinganiswe imizuzwana embalwa futhi imiphumela iyarekhodwa.
Kamuva, umugqa omkhulu we-spectral uyanqunywa. Uma lo mugqa ungaphansi kuka-1kHz, ukuhlaziya kuzophindwa ngebhendi engu-1 kHz ububanzi. Ibanga lefrikhwensi lizobe selihlukaniswa izikhawu eziyishumi ezibanzi ngokulinganayo ze-100 noma 1000 Hz. Ngayinye yalezi zigaba i ampi-litude enomugqa we-spectral omkhulu kunayo yonke, iphindaphindwa yi- teachingin factor , futhi isethwe njengomkhawulo. Uma inani eliphezulu lilele emaphethelweni e-in – terval, isikhawu esilandelayo sizosethwa kulo mkhawulo.
Umkhawulo wesexwayiso nawo ubekwe ku-50%.

Ngale ndlela umkhawulo we-alamu unganqunywa ngaphandle kolwazi lokusheshisa kwangempela kanye nesivinini. Isici sokufundisa sinquma ukubekezelelana okuvumelekile.
Qaphela: Sicela ungayithinti i-VS11 ngesikhathi sokufundisa.
