Analog sensor ikoreshwa cyane mubikorwa biremereye industry inganda zoroheje ile imyenda 、 ubuhinzi 、 umusaruro nubwubatsi education uburezi bwubuzima bwa buri munsi nubushakashatsi bwa siyansi, nibindi bice. Analog sensor yohereza ikimenyetso gihoraho, hamwe na voltage 、 ikigezweho 、 kurwanya nibindi, ubunini bwibipimo byapimwe. Kurugero, ubushyuhe bwubushyuhe sensor sensor ya gazi sensor igitutu cyumuvuduko nibindi nibisanzwe bigereranya.
Igereranya ryinshi rigereranya naryo rizahura nimbogamizi mugihe cyohereza ibimenyetso, cyane cyane kubintu bikurikira:
1.Electrostatike iterwa no kwivanga
Kwinjiza amashanyarazi biterwa no kuba hariho ubushobozi bwa parasitike hagati yumuzunguruko wamashami abiri cyangwa ibice, kuburyo amafaranga yishyurwa mumashami amwe yimurirwa mu rindi shami binyuze muri parasitike, rimwe na rimwe nanone bizwi nka capacitive coupling.
2, Kwivanga kwa Electromagnetic
Iyo habaye inductance hagati yumuzunguruko ibiri, impinduka zumuyaga mumuzunguruko umwe zifatanije nizindi zinyuze mumashanyarazi, ibintu bizwi nka induction ya electromagnetic. Iki kibazo gikunze kugaragara mugukoresha sensor, dukeneye kwitondera byumwihariko.
3, ibicurane bimeneka bigomba kubangamira
Bitewe no kubika nabi ibice bigize ibice, iposita yanyuma, icyapa cyumuzingo cyacapwe, imbere ya dielectric cyangwa shell ya capacitor imbere mumuzunguruko wa elegitoronike, cyane cyane ubwiyongere bwubushuhe mubidukikije bikoreshwa na sensor, kurwanya insulasiyo bigabanuka, kandi noneho imyanda isohoka iziyongera, bityo bitera kwivanga. Ingaruka zirakomeye cyane mugihe imyanda yamenetse itembera murwego rwo kwinjiza uruziga.
4, Kwivanga kwa radio inshuro nyinshi
Nubusanzwe imvururu zatewe no gutangira no guhagarika ibikoresho binini byamashanyarazi hamwe no kwivanga murwego rwo hejuru.
5.Ibindi bintu bivanga
Byerekeza cyane cyane kubikorwa bidahwitse bya sisitemu, nkumucanga, umukungugu, ubuhehere bwinshi, ubushyuhe bwinshi, ibintu byimiti nibindi bidukikije. Mubidukikije bikaze, bizagira ingaruka zikomeye kumikorere ya sensor, nka probe ihagarikwa numukungugu, umukungugu nibintu byangiza, bizagira ingaruka kumupima. Ahantu h’ubushuhe buhebuje, imyuka y’amazi irashobora kwinjira imbere muri sensor kandi ikangiza.
Hitamo aibyuma bitagira ibyuma, ikaba ikomeye, ubushyuhe bwinshi kandi irwanya ruswa, hamwe n ivumbi namazi birinda kwangirika kwimbere imbere. Nubwo igishishwa cya probe kitagira amazi, ntabwo kizagira ingaruka kumuvuduko wogukurikirana, kandi umuvuduko wa gazi no guhana byihuse, kugirango ugere ku ngaruka zo kwihuta.
Binyuze mu biganiro byavuzwe haruguru, tuzi ko hari ibintu byinshi byo kwivanga, ariko ibi nibisanzwe gusa, byihariye kubintu, bishobora kuba ibisubizo byimpamvu zitandukanye. Ariko ibi ntabwo bihindura ubushakashatsi bwacu kuri analog sensor anti-jamming.
Analog sensor anti-jamming tekinoroji ifite ibi bikurikira:
6.Ikoranabuhanga
Ibikoresho birimo ibikoresho byuma. Umuzunguruko ukeneye uburinzi urawuziritsemo, ushobora gukumira neza kwivanga kwumuriro wamashanyarazi cyangwa magneti. Ubu buryo bwitwa gukingira. Kwikingira birashobora kugabanywa gukingira electrostatike, gukingira electromagnetic gukingira hamwe na magnetique ikingira.
（1） Amashanyarazi
Fata umuringa cyangwa aluminium nibindi byuma bitwara nkibikoresho, kora icyuma gifunze, hanyuma uhuze numuyoboro wubutaka, shyira agaciro k'umuzunguruko kugirango urindwe muri R, kugirango umurima w'amashanyarazi wivanga hanze ntugire ingaruka kumuzunguruko w'imbere, naho ubundi, umurima w'amashanyarazi wakozwe numuzunguruko w'imbere ntuzagira ingaruka kumuzunguruko wo hanze. Ubu buryo bwitwa electrostatike ikingira.
（2） Gukoresha amashanyarazi
Kumurongo mwinshi wa interineti yumurongo wa magnetiki, ihame ryumuvuduko wa eddy rikoreshwa mugukora umurongo mwinshi wa interineti yumuriro wa electromagnetique itanga amashanyarazi ya eddy mubyuma bikingiwe, bitwara imbaraga zumuriro wa magnetique, kandi umurima wa magneti wa eddy uhagarika hejuru Umuvuduko ukabije wa magnetiki yumurima, kugirango umuzenguruko urinzwe urindwe ningaruka zumuriro mwinshi wa electromagnetic. Ubu buryo bwo gukingira bwitwa electromagnetic ingabo.
（3） Umuyoboro muke wa Magnetic Shielding
Niba ari magnetiki yumurongo muto, ibintu bya eddy ntibigaragara muriki gihe, kandi ingaruka zo kurwanya interineti ntabwo ari nziza cyane ukoresheje uburyo bwavuzwe haruguru. Kubwibyo, ibikoresho bya magnetiki bihanitse bigomba gukoreshwa nkigice cyo gukingira, kugirango ugabanye umurongo muke woguhuza umurongo wa magnetiki induction imbere imbere ya magnetiki ikingira hamwe na magneti ntoya. Umuzenguruko urinzwe urinzwe kurinda imbaraga nke za magnetiki guhuza. Ubu buryo bwo gukingira bukunze kwitwa magnetique ikingira. Igikonoshwa cyicyuma cyibikoresho bya sensor ikora nkibikoresho bike bya rukuruzi. Niba irushijeho gushingirwaho, ikina kandi uruhare rwo gukingira electrostatike no gukingira amashanyarazi.
7.Ikoranabuhanga rishingiye
Nubuhanga bumwe muburyo bwiza bwo guhagarika kwivanga ningwate yingenzi yo gukingira ikoranabuhanga. Guhindura neza birashobora guhagarika neza kwivanga hanze, kunoza ubwizerwe bwa sisitemu yikizamini, no kugabanya ibintu bivangwa na sisitemu ubwayo. Intego yo guhagarara ni ebyiri: umutekano no guhagarika ibikorwa. Kubwibyo, guhagarikwa bigabanijwe kuburinzi, gukingira hasi no kwerekana ibimenyetso. Mu ntumbero yumutekano, ikariso na chassis byuma bipima sensor bigomba guhagarara. Ubutaka bwibimenyetso bugabanijwemo ibimenyetso byerekana ibimenyetso hamwe nubutaka bwa signal, ibimenyetso bisa muri rusange ni intege nke, bityo ibisabwa kubutaka biri hejuru; ibimenyetso bya digitale muri rusange birakomeye, kubwibyo ibisabwa kubutaka birashobora kuba munsi. Imiterere itandukanye ya sensor igaragara nayo ifite ibisabwa bitandukanye munzira igana kubutaka, kandi uburyo bukwiye bwo guhitamo bugomba guhitamo. Uburyo busanzwe bwo guhingamo burimo ingingo imwe hamwe nubutaka bwinshi.
(1) Ingingo imwe
Mumuzunguruko muke, mubisanzwe birasabwa gukoresha ingingo imwe ihagarara, ifite umurongo wa radiyo hamwe numurongo wa bisi. Imirasire ya radiologiya isobanura ko buri muzunguruko ukora mumuzunguruko uhujwe neza na zeru zishobora gukoreshwa ninsinga. Guhagarara kwa busbar bivuze ko imiyoboro yo mu rwego rwo hejuru ifite igice runaka cyambukiranya imipaka ikoreshwa nka bisi ihagarara, ihujwe neza na zeru ishobora kuba. Ubutaka bwa buri gice gikora mumuzunguruko kirashobora guhuzwa na bisi iri hafi. Sensor n'ibikoresho byo gupima bigize sisitemu yuzuye yo gutahura, ariko birashobora kuba kure.
(2) Impamvu nyinshi
Imirongo yihuta cyane irasabwa kwemeza ingingo nyinshi. Umuvuduko mwinshi, ndetse nigihe gito cyubutaka bizagira impagarike nini ya impedance igabanuka, hamwe ningaruka zo kugabura ubushobozi, ntibishoboka ko habaho ingingo imwe, kubwibyo rero birashobora gukoreshwa muburyo bwubutaka bwo hasi, aribwo buryo bwo kugwiza ibintu byinshi, ukoresheje inzira nziza kuri zeru ahantu hashobora kwerekanwa kumubiri windege, umuvuduko mwinshi wumurongo kugirango uhuze nindege iyobora hafi yumubiri. Kuberako umuvuduko mwinshi wumubyigano windege yindege ari nto cyane, ubushobozi bumwe kuri buri mwanya buremewe cyane, kandi capacitor ya bypass yongeweho kugirango igabanye umuvuduko wa voltage. Kubwibyo, iki kibazo kigomba gufata ingingo nyinshi zifatika.
8.Gushungura tekinoroji
Akayunguruzo ni bumwe mu buryo bufatika bwo guhagarika AC serial uburyo bwo kwivanga. Akayunguruzo gasanzwe mumuzunguruko wa sensor igaragaramo akayunguruzo ka RC, akayunguruzo ka AC hamwe nukuri kwamashanyarazi.
. Twabibutsa ariko ko RC muyunguruzi igabanya urukurikirane rwimikorere ititaye kumafaranga yihuta.
.
. Kugirango wirinde kwivanga kwatewe ninzitizi nyinshi binyuze mukurwanya imbere kwamashanyarazi, RC cyangwa LC decoupling filter igomba kongerwaho amashanyarazi ya DC ya buri muzunguruko kugirango ushungure urusaku ruke.
9.Ikoranabuhanga ryo guhuza amashanyarazi
Inyungu nyamukuru yo guhuza amafoto ni uko ishobora guhagarika neza impiswi yimisozi nubwoko bwose bwivanga urusaku, kuburyo igipimo cyerekana ibimenyetso-urusaku mubikorwa byo kohereza ibimenyetso byateye imbere cyane. Urusaku rwivanga, nubwo hari intera nini ya voltage, ariko ingufu ni nto cyane, irashobora gukora gusa imbaraga zidafite imbaraga, kandi ifoto yumuriro winjiza igice cyumucyo utanga diode nakazi kameze ubu, icyerekezo rusange cyamashanyarazi ya 10 ma ~ 15 ma, niyo rero niyo haba hari intera nini yo kwivanga, intambamyi ntizishobora gutanga ibihagije kandi byahagaritswe.
Reba hano, ndizera ko dusobanukiwe neza nimpamvu zoguhuza analog sensor nuburyo bwo kurwanya interineti, mugihe ukoresheje sensor ya analog, niba habayeho kwivanga, ukurikije ibivuzwe haruguru umwe umwe iperereza, ukurikije uko ibintu bimeze kuri fata ingamba, ntugomba gutunganya buhumyi, kugirango wirinde kwangirika.
