Zoyenera kuchita ngati choyezera mafuta sichikugwira ntchito

Nthawi zonse ndikofunikira kuti dalaivala adziwe kuti ndi mtunda wotani omwe adzakhale ndi mafuta otsala mu thanki. Kuwerengera kwamitengo yeniyeni ya mtunda wanthawi yomweyo kapena wapakati, kuchuluka kwa malita amafuta mu thanki, ndikusungira mtunda kumachitidwa ndi kompyuta yomwe ili pa bolodi, koma sensor level mafuta (FLS) imapereka chidziwitso choyambirira izo.

Popeza mawonekedwe a thanki sasintha, voliyumu imakhala ndi chidziwitso chodziwika bwino pamlingo.

Cholinga cha gauge yamafuta mgalimoto

Kusiyanitsa pakati pa cholozera ndi sensa. Yoyamba ili pa dashboard ndipo ndi muvi kapena cholozera cha digito.

Mulimonsemo, manambalawa amapangidwanso ndi sikelo ya analogi, zilibe kanthu, mwa mawonekedwe a gawo lowonetsera kapena chipangizo chosiyana chokhala ndi magnetoelectric drive ya muvi. Umu ndi ulemu wochuluka ku miyambo kuposa kufunikira, koma ndi momwe zilili.

Cholozeracho chimalumikizidwa ndi sensa, ndipo mawonekedwe amagetsi pazida zonse ziwiri amasankhidwa m'njira yoti cholakwikacho chikhale chocheperako chovomerezeka pamlingo uliwonse.

Sikofunikira kukhala ndi mawonekedwe amtundu wa pointer ndi FLS. Komanso, pafupifupi nthawi zonse amakhala opanda mzere. Koma pamene makhalidwe awiri ayikidwa pamwamba pa chimzake, ndi zina zowonjezera zopanda mzere wa sikelo zikuwonjezedwa kwa iwo, ndiye kuti chidziwitso chowonetsedwa chikhoza kudaliridwa.

Pankhani yokonza makompyuta a chizindikiro cha sensor, simuyenera kudandaula za kudalirika kwa kuwerenga. Wowongolera mapulogalamu amatha kugwiritsa ntchito chilichonse chovuta kwambiri, ngakhale sichinafotokozedwe mosanthula. Ndikokwanira kuwerengera zowerengera, zomwe zimachitika panthawi yachitukuko.

Mtundu wovuta kwambiri wa thanki, pomwe, kutengera momwe mafuta alili, kusuntha kwa choyendetsa cha sensor kumakhudzidwa ndi kuchuluka kwamadzimadzi m'mayunitsi a voliyumu yosiyana kwambiri, kumayikidwa mu kukumbukira kwa chipangizocho mu mawonekedwe a tebulo.

Kuphatikiza apo, eni ake nthawi zonse amatha kuyika zinthu zawo zowongolera panthawi yosinthira makonda kuti awerenge zolondola kwambiri. Umu ndi momwe makompyuta amtundu uliwonse, omwe amaikidwa ngati zida zowonjezera, nthawi zambiri amagwira ntchito.

Malo a chipangizocho

LLS nthawi zonse imayikidwa mwachindunji mu thanki yamafuta. Mapangidwe ake ndi osagwirizana ndi mpweya wa petulo kapena dizilo ndipo mwayi umadutsa pamwamba pa thanki, yomwe nthawi zambiri imaphatikizidwa ndi doko lothandizira pampu yamafuta.

Sensor yokhayo imaphatikizidwanso mu module imodzi nayo.

Mitundu ya masensa amafuta

Pali mfundo zambiri zosinthira malo kukhala chizindikiro chamagetsi.

Ena amakonza ndendende malo amadzimadzi, ndiye kuti, malire pakati pa zinthu zamitundu yosiyanasiyana, koma ndizotheka kuyeza voliyumu mwachindunji. Palibe chosowa chapadera cha izi, ndipo zipangizozi zidzakhala zovuta komanso zodula.

Pali mfundo zingapo zofunika:

• zamagetsi;
• mu atomu;
• capacitive;
• ultrasonic.

Pakhoza kukhalanso kusiyana kwa njira yolankhulirana ndi cholozera:

• analogi;
• pafupipafupi;
• chisonkhezero;
• encod mwachindunji ndi data bus algorithm.

Chipangizocho chimakhala chosavuta, chimapangidwira kwambiri, mtengo wake umakhala wovuta kwambiri. Koma palinso ntchito zapadera, monga malonda kapena masewera, kumene kulondola ndi kukhazikika ndizofunikira kwambiri.

Chipangizo ndi ndondomeko ya ntchito

Nthawi zambiri, kuwongolera pamwamba kumachitika pogwiritsa ntchito choyandama. Ikhoza kulumikizidwa ndi Converter m'njira zosiyanasiyana.

zoyandama

Chosavuta ndikulumikiza choyandama ku potentiometer yoyezera pogwiritsa ntchito lever. Kusuntha malo a osonkhanitsa panopa kumayambitsa kusintha kwa kukana kwa variable resistor.

Itha kukhala mu mtundu wosavuta kwambiri wa waya kapena mawonekedwe a zopinga zokhala ndi matepi ndi zolumikizirana, zomwe slider imayenda, yolumikizidwa ndi zoyandama kudzera pa lever.

Zida zotere ndizotsika mtengo, komanso zolakwika kwambiri. Polumikiza kompyuta, amayenera kuyesedwa ndi kudzazidwa ndi ma voliyumu odziwika amafuta.

Maginito

Mukhoza kuchotsa lever polumikiza potentiometer ku zoyandama ndi maginito. Maginito okhazikika olumikizidwa ndi choyandamacho amayenda motsatira njira yolumikizirana ndi ma taps kuchokera ku zopinga zamakanema. Zitsulo flexible mbale zili pamwamba pa nsanja.

Malinga ndi malo a maginito, mmodzi wa iwo amakopeka ndi izo, kutseka pa nsanja lolingana. Kukana kwathunthu kwa gulu la resistors kumasintha molingana ndi lamulo lodziwika.

Pakompyuta

Kukhalapo kwa zida zamagetsi mu sensa kumalola kuti zipangizo zosiyanasiyana ziphatikizidwe m'gululi. Mwachitsanzo, sensor capacitive, pomwe mbale ziwiri za capacitor zili molunjika mu thanki.

Pamene imadzaza ndi mafuta, mphamvu ya capacitor imasintha chifukwa cha kusiyana kwa dielectric nthawi zonse pakati pa mpweya ndi mafuta. Mlatho woyezera umatenga kupatuka kuchokera ku dzina ndikumasulira kukhala chizindikiro cha mulingo.

The akupanga sensa ndi yaying'ono emitter ya mafunde apamwamba-pafupipafupi amayiwidwe ndi wolandila chizindikiro chonyezimira. Poyesa kuchedwa pakati pa kutulutsa ndi kusinkhasinkha, mtunda wofika pamlingo ukhoza kuwerengedwa.

Malinga ndi mtundu wa mawonekedwe, chitukuko chikuyenda molunjika pakulekanitsa sensa mu node yodziyimira payokha ya basi imodzi yagalimoto. Monga zida zina zonse, imatha kutumiza zambiri pabasi iyi poyankha pempho lochokera pa dashboard.

mavuto ofanana

Zolephera za FLS zimalembedwa ndi kuwerenga kwake kolakwika kapena kusakhalapo kwawo konse. Pazochitika zodziwika bwino zamakina olumikizana ndi choyandama ndi potentiometer ya analogi, singano ya pointer imayamba kunjenjemera, kupitilira kapena kunyalanyaza zowerengera. Izi zimakhala pafupifupi nthawi zonse chifukwa cha kuvala kwamakina kwa gulu lolumikizana la resistor variable.

Mlandu wachiwiri wachiwiri ndi kusintha kwa kuchuluka kwa zoyandama chifukwa cha kuwonongeka kwa zinthu kapena kuzidzaza ndi mafuta. Mpaka kumaliza kumira ndikuwerenga ziro mosalekeza.

Masensa amagetsi pakagwa vuto la zinthu amangosiya kuwerengera. Nthawi zina izi zimachitika chifukwa cha mawaya omwe satetezedwa kuzinthu zakunja. Zizindikiro zimalephera kawirikawiri.

Momwe mungayang'anire magwiridwe antchito a sensor

Pachipangizo chilichonse chokhala ndi potentiometer, pali tebulo lowerengera mgwirizano pakati pa kukana ndi kuchuluka kwamafuta.

Ndikokwanira kutenga miyeso ndi multimeter mu ohmmeter mode pazigawo zingapo, mwachitsanzo, thanki yopanda kanthu, malo osungirako, mlingo wapakati ndi thanki yonse.

Ndi kupatuka kwakukulu kapena kusweka, sensa imakanidwa.

Momwe mungayang'anire sensor level mafuta (FLS)

Njira zokonzera gauge yamafuta

FLS yamakono sichitha kukonzedwa ndikusinthidwa ngati msonkhano. Pambuyo poyang'ana mawaya ndi kuyesa kukana pa cholumikizira, sensa imachotsedwa mu thanki pamodzi ndi mpope ndi kuyandama pa lever.

Izi zidzafuna mwayi wofika pamwamba pa thanki, yomwe nthawi zambiri imakhala pansi pa mpando wakumbuyo kapena thunthu. Sensa imachotsedwa pa module ya pampu ndikusinthidwa ndi yatsopano.

Kupatulapo kungawonekere kuphulika kwa waya. Soldering ndi kudzipatula mfundo yopuma ikuchitika. Koma kawirikawiri chifukwa cha kulephera ndi kuvala kwa mikangano pamwamba pa potentiometer.

Kubwezeretsedwa kwake ndikotheka, koma sikungatheke, chipangizo chokonzedwanso ndi chosadalirika, ndipo chatsopanocho ndi chotsika mtengo.
