Ekulawulweni kwenqubo yezimboni, ngenxa yokusebenza okuqhubekayo kokukhiqiza, kunezidingo eziphezulu zokuthembeka kwemishini, futhi kusetshenziswa ubuchwepheshe obuningi obungadingeki ukuqinisekisa ukuthembeka kokulinganisa nokulawula.
Ngaphezu kwebhalansi yezakhi zesistimu ye-DCS, isidingo sebhalansi yezakhi siphinde sibekwe phambili endaweni.izinzwaUhlelo lwe-DCS luthemba ukwazi isimo sokusebenza salowo nalowoinzwangesikhathi futhi uthole iphutha ngesikhathi obstacle. Ngendlela yendabuko yokulinganisa, izimpawu zezinzwa eziningi ze-analog zixhunywana ngebhokisi lokuhlangana futhi zibe yisignali eyodwa, ngakho izimpawu zenzwa ngayinye azisazimele..
Ngaphezu kwalokho, ithuluzi alikwazi ukuthola izinkinga ku-inthanethi futhi lithole amaphutha, ngakho-ke kunzima ukuhlangabezana nezidingo zokuthembeka okuphezulu ekukhiqizweni okuqhubekayo. Ligcinwe ku-sensor yesisindo yedijithali ye-teller Toledo..
Iyunithi ine-microprocessor, engazixilonga. Umhlangano ngamunye unekheli lawo. Ithuluzi lingaqapha ukuphuma kwebhokisi lenzwa ngayinye ku-inthanethi futhi lenze ukucubungula okuhlakaniphile, okungagcini nje ngokuthuthuka kakhulu.. Akugcini nje ngokuthuthukisa ukuthembeka kohlelo lokukala, kodwa futhi kungaxazulula kalula izidingo zezinzwa ezithile ze-analog, njengesisindo esikhulu se-tare, inani elincane kanye nokutholwa komthwalo wesignali.
Engeza eyakho eyingqayizivele hubuchwepheshe bokuguqula umkhiqizo / ukuguqulwa kwe-D ngokunemba okuphezulu
•Cubuchwepheshe besengezo sesignali yedijithali yenzwa egcwele yonke indawo kanye nekhono lokuxhumana elisheshayo elivikela ukuqhuma ibanga elide kwenza ukusebenza kudlule umkhawulo wezinzwa ze-analog futhi kufinyelele tUkunemba kwe-oin C6 kudlule izitifiketi eziningi zomhlaba wonke, futhi kuyinzwa yangempela yokukala yedijithali: iminyaka engaphezu kweyishumi, izinzwa zokukala zedijithali zeCI-Toledo eyinhloko ibilokhu isetshenziswa kabanzi emhlabeni mi-ore engaphezu kuka-500000.
Uma kuqhathaniswa nenzwa ye-analog, izici ezilandelayo zenzwa yokulinganisa yedijithali zingahlangabezana kangcono nezidingo zokulawula inqubo: ukuthembeka okuphezulu kanye nokulwa nokuphazamiseka.
Amandla aqinile kanye nokusebenza kahle kokuvikela umbani. Inzwa ye-analog inikwa amandla yithuluzi, futhi i-voltage ethokozisayo yebhuloho layo ilingana nokunikezwa kwamandla kwethuluzi langaphandle. Emkhakheni wezimboni, ithuluzi kanye nenzwa kuthinteka kakhulueUkuphazamiseka kogesi kanye nokuqondisa kokuqhuma kuzobangela ukungazinzi kwedatha futhi kushise ngisho nenzwa ngokushesha. Inzwa yedijithali isebenzisa ubuchwepheshe bokushisela insimbi engagqwali evalwe ngokuphelele futhi igcwele igesi ye-ammonia ukuvikela ingaphakathi..
Isekethe isebenza ngokuthembeka futhi izinga lokuvikela lifinyelela ku-IP68. Ishubhu ifakwe amasekethe ahlukahlukene okuvikela kanye nomklamo wokuvikela umbani. Ukunikezwa kwamandla okunikezwa yithuluzi kuqala kucutshungulwa bese kusetshenziselwa ibhuloho ngemva kokuzinza..
Lokhu kuvusa inkanuko kususa ukuphazamiseka kokuphuma kwamandla kagesi kanye nombani, kwenza inzwa ikhiphe izimpawu ezizinzile, futhi iqinisekise ukusebenza okuvamile kwenzwa..
Uhlelo lungaqinisekisa ukuqhubeka kokukhiqiza futhi lufeze izinto ezintsha ezingezona ezakho. Ithuluzi aligcini nje ngokuqapha izimo zokusebenza zezinzwa ezahlukene zedijithali ngaso sonke isikhathi, kodwa futhi libona iphutha lezinzwa..
Ithuluzi lingaqala ngokuzenzakalelayo imodi yokusebenza engaphazanyiswa, futhi lisengaqinisekisa ukulinganiswa ngesikhathi esithile nangokunemba okuthile, ngaphandle kokubangela ukuvalwa kokukhiqiza. Ngesikhathi esifanayo, ithuluzi lizothumela isignali.
Kumsebenzisi, thola inzwa enephutha bese udinga ukushintshwa. Lingisa umcimbi omkhulu uhlelo lwenzwa olungenakuwulinganisa uma inzwa inephutha, okuholela ekuvaleni.
- kuyinto enhle kakhulukuyinkimbinkimbi into ethile, futhi izinhlelo eziningi zamathangi ezinto zokwakha kunzima ukwengeza isisindo noma cha; Ukulinganiswa kungenziwa ngokusebenzisa ikhodi yokulenga intambo futhi inzwa yedijithali ingasetshenziswa ukulinganisa.
Yebo. Lokhu kungenxa yokuthi inzwa yedijithali ikhishwe kunzwa nge-dynamometer ejwayelekile yamazwe ngamazwe ekukhiqizweni; Ukulinganiswa kwenziwa, futhi inani lamagama aphumelelayo okukhishwayo kanye nenani lamandla ajwayelekile kuyithuluzi elihambisanayo..
Lokho okufundwa yimitha inani lesisindo empeleni elilinganiswa yinzwa yedijithali. Akukho ukulahleka phakathi. Ngakho-ke, ukulinganisa kungagwenywa eShayina.
•kuyilapho izinzwa ze-analog nezinsimbi zokulinganisa
Uma uhlelo lokulinganisa i-analog seluhlanganisiwe, isixhumanisi ngasinye soxhumano sizolahlekelwa yisignali. Isignali elinganiswe yithuluzi ayilingani ngokuphelele nomphumela wenzwa.
Ngakho-ke, ukusetha insimu yesistimu kumele kwenziwe ngesikhathi sokufaka isicelo. Ibanga lokudlulisela lide, isivinini sokuxhumana siyashesha, futhi umphumela wokulwa nokuvinjelwa ubalulekile. Ileveli = isignali yenzwa ye-analog incane kakhulu, futhi kulula ukuyifaka. sAkunandaba nokuphazamiseka kwemvamisa yomsakazo kanye nokuphazamiseka kwe-electromagnetic. Kodwa-ke, ngenxa yethonya lokumelana nekhebula, ibanga lokudlulisa isignali lifushane. Ukukopela okulinganisiwe kwesisindo kukhulu kakhuludkunzima ukulawula. Inzwa yedijithali inesignali yedijithali, engagcini nje ngokuba phezulu kunesignali ye-analog, futhi akulula ukuyiphazamisa, kodwa futhi idluliselwa ngokwephrothokholi yokuxhumana yebhasi lensimu ye-bifbus. Isivinini sokuxhumana singama-letters ayishumi ajwayelekile angu-R $485. Sishesha kakhulu futhi sinekhono lokulungisa amaphutha okuxhumana, siqinisekisa idatha esheshayo nethembekile. Ngenxa yobumfihlo besivumelwano, isayithi alikwazi ukukopela. Umehluko we-engeli kulula ukuwulungisa..
Ngomzimba wesikali owakhiwe inzwa ye-analog, ngenxa yokungahlukaniswa kwesiginali, ikhodi izongezwa kunzwa ngayinye futhi i-potentiometer ebhokisini lokuhlangana izosetshenziswa ukulungisa umehluko we-engeli ngesikhathi sokulinganisa, dNgenxa yokusebenzisana phakathi kwezinzwa, kudinga ukulungiswa ngokuphindaphindiwe, okudla isikhathi futhi kukhathazayo. Kulula kakhulu ngomzimba wesikali owakhiwe ngezinzwa zedijithali ukuba uhlinzwe ubuhle.
Ithuluzi lingafunda amandla enzwa ngayinye emakhoneni amane, ngakho uma nje umthwalo owodwa ungeziwe ekhoneni ngalinye, ithuluzi lingakwazi ukubala umehluko we-engeli wephuzu ngalinye, futhi lingakala ngokuzenzakalelayo..
Ukulungiswa komehluko we-engeli kususa inkinga yokulayisha nokwephula ikhodi ngokuphindaphindiwe, futhi kuthuthukisa ukusebenza kahle. Ukulungiswa komehluko we-engeli kungaqedwa ngomthwalo owodwa wokujaha, okulula kakhulu futhi okusheshayo.
Inzwa ye-analog yokulungisa elula
Ekukhiqizeni, isinxephezelo sokushisa senziwa kanye nekhebula, ukuze kuqedwe ithonya lokushisa lokumelana nekhebula. Uma ikhebula lenzwa yokukhetha isikhunta lonakele futhi lixhunywe ngokuthanda, khona-ke rokuholela emaphutheni okulinganisa. Ngakho-ke, uma ibanga lide, inzwa idinga ukwenziwa ngokwezifiso. Uma inzwa ishintshwa, idinga ukufakelwa kabusha, okuyinto engathandeki kakhulu ekusetshenzisweni kwangempela.
Ukudluliselwa kwedijithali
Inzwa isebenzisa ipulaki yendiza yelogo yemoto, engagcini nje ngokuqinisekisa izinga lokuvikelwa elingu-if68, kodwa futhi eyenza inzwa kanye nekhebula kube amadivayisi amabili azimele. Shintsha inzwa noma ikhebula
Kulungile. Angidingi izintambo. Njengoba i-transmission iyisignali yedijithali, ubude bomugqa wesistimu kagesi bungashintshwa njengoba kudingeka ngaphandle kokuthinta ukunemba kokulinganisa. Lapho inzwa yedijithali ishintshwa, isigaba kuphela.
Uma ipharamitha yokuvala ifakwa ku-sensor entsha, asikho isidingo sokuthilungisa kabusha uhlelo. Izindleko zizonke zohlelo ziphansi. Ngokombono wezindleko zohlelo, hnoma kunjalo, njengoba inzwa yedijithali inciphisa ukususwa kwamaphutha kanye nezindleko zohlelo lokusebenza kuhlelo lokusebenza (isibonelo, kulula ukulungisa umehluko we-engeli), kungenzeka ukugwema ukulinganiswa, ukufaka esikhundleni inzwa ngaphandle kokulungiswa kabusha, kanye tUkuzixilonga kanye nokusebenza okungaphazanyiswa kwe-word sensor kuthuthukisa ukuthembeka kohlelo futhi kunciphisa isikhathi sokungasebenzi. E-China, izindleko zizonke zohlelo ziphansi kunezohlelo lwe-analog sensor.
