Chii chinonzi phase sensor
Ma phase sensors zvinhu zvakakosha zvemagetsi zvemotokari uye anoshandiswawo muminda yakasiyana-siyana kuyera huwandu hwemuviri hwakadai senzvimbo uye kumhanya kwezvinhu.
Mumunda wemotokari, inonyanya kushandiswa kuona nguva yevharuvhu yeinjini kuti ione nguva yakakodzera yekupisa.
Kune mhando dzakasiyana dzema phase sensors, ayo akapatsanurwa mumhando dzemagnetoelectric neHall, zvichigadzira masaini esine wave nesquare wave zvichiteerana. Kazhinji, inosanganisirawo ma photoelectric sensors ne magnetic sensors.
Sensor yechikamu che photoelectric inoburitsa masaini emazinga akasiyana nekutenderedza panel yechiratidzo uye kubatidza kana kudzima phototransistor zvichienderana nekutumira kana kuvharira chiedza.
Rudzi rweHall mumasensa emagetsi anoshandisa Hall effect, nepo rudzi rwemagnetoelectric ruchishandisa musimboti we magnetic induction. Kana rotor yechiratidzo ichitenderera, shanduko mudunhu remagetsi inokonzera kuti simba remagetsi rienderane nealternating electromotive rigadzirwe mu induction coil.
Musimboti wayo wekushanda ndewekuti uwane basa iri nekuona nzvimbo uye kutenderera kweAngle yecamshaft. Coil yekuona yemukati inogona kunzwa zvinhu zvesimbi zviri pedyo. Kana pasina zvinhu zvesimbi, LC circuit inorira uye voltage inobuda inokwira. Kana chinhu chesimbi chasvika, eddy currents inokonzerwa mu detection coil, inductance ye coil inochinja, LC parallel circuit inobvisa harmonizes, uye output voltage inodonha. Shanduko iyi inoenderana nedaro rechinhu chesimbi. Phase change inowanikwa nekuyera output voltage change.
Nguva yevharuvhu inoreva Angle apo mavharuvhu ekupinda nekubuda einjini anovhurwa nekuvharwa kana tichitarisa kutenderera kwe crankshaft. Nguva chaiyo yevharuvhu inokosha pakushanda kweinjini, zvichikanganisa simba, kuchengetedza mafuta uye kuburitswa kwemhepo.
Sensor ye phase ine basa rekutarisa kururama kwechikamu che valvu. Kana paine chisina kumira zvakanaka, alarm inorira uye mwenje wekutadza kweinjini unovheneka.
Ma phase sensors, ayo ariwo mazwi akajairika e camshaft position sensors uye crankshaft position sensors, ndiwo hwaro hwakakosha hwekuona nguva yekupisa injini.
Sensor yechikamu checamshaft inoongorora nzvimbo yekutenderera kwecamshaft uye inopinza chiratidzo kuECU, inova ndiyo chiratidzo chikuru chekudzora kupisa.
Sensor yenzvimbo yecrankshaft inoona angle yecrankshaft yeinjini nepakati pepiston, uye inotumira masaini kukombiyuta yeinjini kuti idzore nguva yekupisa uye kupinza mafuta. Ndiyowo nzvimbo yechiratidzo chekuyera kumhanya kweinjini.
Mune dzimwe nzvimbo, ma phase sensors, zvichibva panheyo yekuyera phase, anoburitsa masaini kuzvinhu uye anoverenga ruzivo rwenzvimbo yezvinhu nekuyera musiyano wephase pakati pemasaini anoburitswa neanoratidzwa.
Inoshandiswa zvakanyanya muminda yakaita seyemaindasitiri otomatiki, aerospace, kurapwa, uye robotics, uye inogona kubatsira mukutonga kwekufamba kwemarobhoti akazvimirira, kudzora kufamba kwemotokari dzekutakura, uye kuongororwa kwekurapa, nezvimwewo.
Sensor yechikamu chimwe chezvinhu zvikuru zvemazuva ano zvekutonga injini dzemotokari, zvinoumbwa nemasensor enzvimbo dzecrankshaft uye masensor enzvimbo dzecamshaft. Sensor yenzvimbo dzecrankshaft ine basa rekuunganidza kumhanya kweinjini uye masaini eAngle ecrankshaft, zvichipa referensi yenguva yekupisa nekupinza mafuta. Sensor yenzvimbo dzecamshaft inovimbisa kuitwa kwakarurama kwekutonga kwekuisa mafuta nekudzivirira kudonha nekuona nzvimbo yepakati pepamusoro pesimba recylinder [3] [8]. Izvi zviviri zvinoshanda pamwe chete kuburikidza nekubatanidza chikamu, izvo zvinonyanya kukosha panguva yekutanga uye zvinoda kuenzaniswa kwakanyatsojeka kwenguva yekutanga yekupisa [6]. Boka iri resensor rinonzi "sensor yechikamu" nekuda kwebasa rayo rose rekudzora pamusoro pechikamu chechitima chevharuvhu nenguva yekupisa.
Kukundikana kwesensa yechikamu kunogona kukonzera matambudziko akawanda.
Dambudziko rekutanga nderekuoma kwekuvhura injini. Phase sensor inofanira kupa ECU ruzivo rwenzvimbo yecrankshaft, uye ECU inoverenga nguva yekupisa uye huwandu hwemafuta zvichibva paruzivo urwu. Kana phase sensor ikatadza kushanda zvakanaka, haigone kupa ruzivo rwakarurama. ECU haigone kudzora kupisa uye mafuta, zvichiita kuti kutanga kweinjini kuve kwakaoma kana kutotadza.
Zvadaro pane kusagadzikana kwekushanda. Mumamiriro ezvinhu akajairwa, phase sensor inotarisa nzvimbo ye crankshaft, zvichibvumira injini kugadzirisa nguva yekupisa uye huwandu hweinjini kuti ive nechokwadi chekuti injinjini inomhanya zvakanaka. Kana phase sensor ikatadza kushanda zvakanaka, ruzivo rwunotumirwa kuECU ruchava rusina kururama, uye kutonga kweECU pamusoro peinjini kuchachinja. Nekuda kweizvozvo, kumhanya kwekushanda kuchava kusina kugadzikana, uye matambudziko akadai se injit jitter uye kumhanya kunochinja-chinja zvinogona kuitika.
Zvichakonzerawo kusamhanya zvakanaka. Kana mota ikamhanya zvakanyanya, sensor ye phase inofanira kupa ruzivo rwakarurama uye rwakarurama panguva chaiyo senge nzvimbo ye crankshaft, kuitira kuti ECU ikwanise kugadzirisa nekukurumidza nzira dzekubatidza nekuisa mafuta kuti ienderane nezvinodiwa nemotokari yekumhanyisa. Kana paine dambudziko, ruzivo rwacho haruna kururama, ECU haigone kugadzirisa nemazvo, simba reinjini rinokanganiswa, kumhanya kunenge kusina simba, uye kunyange kunzwa kusingafadzi kunogona kuitika, izvo zvinokanganisa ruzivo rwekutyaira.
Pamusoro pezvo, rambi rekutadza richabatidzwa. Kana sisitimu yekuongorora zvikanganiso yemotokari ikaona kutadza kwesensa yechikamu, ichatanga kodhi yekutadza, uye rambi rekutadza kweinjini riri padashboard richabatidzwa, zvichiyeuchidza muridzi wemotokari kuti pane dambudziko nemotokari.
Pakupedzisira, kushandiswa kwemafuta kunowedzera. Kukundikana kwesensa yechikamu chemagetsi kunoita kuti ECU isakwanise kudzora vhoriyamu yemafuta. Vhoriyamu yemafuta inogona kunge yakawandisa kana kuti shoma, zvichikonzera kutsva kusina kukwana uye mafuta asingashandiswe zvakanaka kuita simba, zvichiita kuti kushandiswa kwemafuta kuwedzere.
Mukupedzisa, kutadza kushanda zvakanaka kwe phase sensor kunokanganisa zvikuru mota. Kana matambudziko ari pamusoro apa akaitika, zvakakosha kuti uongorore phase sensor nekukurumidza uye, kana zvichidikanwa, uigadzirise kana kuitsiva kuti mota idzorere pamamiriro ayo akajairika.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
