Air pressure sensors, zvinhu zvakakosha mumakumi ezviuru zvekushandisa, zvigadziriso zvakagadzirirwa kuyera uye kutarisa kudzvanywa kwemhepo munzvimbo dzakasiyana siyana. Aya masensa anoita basa rakakosha mukuona kushanda zvakanaka, kuchengetedzeka, uye kuita kwemasisitimu mumotokari, ndege, kufembera kwemamiriro ekunze, uye zvikamu zvemagetsi zvevatengi, pakati pezvimwe. Kunzwisisa mashandiro anoita ma sensors emhepo kunosanganisira kunyura mukati memisimboti yekunzwa kudzvanywa kwemhepo, tekinoroji iri kuseri kwema sensors aya, uye mashandisiro awo akasiyana.
Iyo Yekushanda Nheyo yeDzvinyiriro Sensors
Pressure sensors zvishandiso zvinokwanisa kuona uye kuyera mhepo yemhepo, inoshandiswa zvakanyanya mune meteorology, ndege, mota, uye mamwe akawanda minda. Aya masensor anoshandisa akasiyana tekinoroji ekunzwa kushandura shanduko shanduko kuita masaini emagetsi, anosanganisira piezoelectric, capacitive, uye resistive tekinoroji.
Detailed Analysis yeSensing Technologies:
- Piezoelectric Technology:Piezoelectric sensors inoshanda zvichienderana nepiezoelectric mhedzisiro yezvinhu, uko mukati memukati shanduko inochinja inoburitsa machaji emagetsi pasi pekumanikidzwa. Aya masensa anokosheswa nekuda kwekunzwa kwavo kwepamusoro uye nekukurumidza kupindura nguva, zvichiita kuti ive yakakosha mumidziyo yerabhoritari yepamusoro-chaiyo uye maitiro chaiwo emaindasitiri.
- Capacitive Technology:Capacitive sensors inoyera shanduko yedzvinyiriro nekuona mutsauko we capacitance pakati pemarata maviri esimbi. Sezvo kumanikidzwa kwemhepo kunochinja, chinhambwe pakati pemahwendefa chinoshanduka, kushandura capacitance. Iyi tekinoroji yakanakira zviteshi zvemamiriro ekunze, ichipa yakakwirira-chaiyo yemamiriro ekunze kuverengera kwakakosha pakufanotaura kwemamiriro ekunze.
- Resistive Technology:Resistive sensors inoshanda nekuona shanduko mukupikisa kunokonzerwa nekudzvanywa kwakasiyana. Aya ma sensors ari nyore, anodhura, uye anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana uye mota dzekushandisa.
Nyaya Yenyaya:
Iko kushandiswa kwecapacitive pressure sensors muzviteshi zvekufungidzira mamiriro ekunze inoshanda semuenzaniso wakanaka wekuti kuyerwa kwedziviriro kwakaringana kungawedzera sei kurongeka kwekufanotaura, kwakakosha kuronga zviitiko zvekunze uye marongero endege.
Muzviteshi zvemamiriro ekunze, capacitive pressure sensors inoshandiswa kuyera kumanikidzwa kwemhepo. Sezvo machinjiro ehurefu hwemamiriro ekunze (akadai seyepamusoro nepasi-pressure system) anofamba, mhepo yemuchadenga inosiyana. Nekuramba vachiongorora shanduko idzi dzekumanikidza, nyanzvi dzezvemamiriro ekunze dzinogona kuronda mafambiro emamiriro ekunze uye kufanotaura kuchinja kwemamiriro ekunze (zvakadai semamiriro ekunze akajeka, ekunaya, kana madutu), nokudaro achinatsiridza huchokwadi hwekufanotaura kwemamiriro ekunze.
Capacitive pressure sensors inowanzo sanganisira mahwendefa maviri esimbi anofanana, nenzvimbo iri pakati pawo izere ne insulating material (dielectric). Kana kudzvinyirirwa kwekunze kuchiiswa kune sensor, chinhambwe chiri pakati peaya mahwendefa esimbi maviri anoshanduka, nekudaro achichinja capacitance yavo (kukwanisa kuchengeta charge). Shanduko ye capacitance yakanyatso kuenzana nekumanikidzwa kunoshandiswa, uye nekuyera shanduko iyi, kudzvanywa kwekunze kunogona kuverengerwa nemazvo.
Iyo yakanyanya senitivity uye kurongeka kwecapacitive pressure sensors inovaita maturusi akakosha mukufembera kwemeteorological. Kuyera kwakaringana kudzvanyirira kunobatsira vanofanotaura zviri nani kushanduka kusinganzwisisike mumhepo yemhepo, iyo inowanzoratidza shanduko huru yemamiriro ekunze. Zvakare, aya masensa anogona kushanda akadzikama pasi pemamiriro ekunze akanyanya, achivimbisa kuenderera uye kuvimbika kweiyo data.
Technology Kuenzanisa:
Kuenzanisa matekinoroji aya kunoburitsa kuti piezoelectric sensors inokunda mukurongeka uye kumhanya kwekupindura asi zvinouya nemutengo wakakwira. Capacitive sensors inoita zvakanaka mukugadzikana uye nekurongeka, yakanakira kuyerwa kwemamiriro ekunze. Resistive sensors inofarirwa nekuda kwekudhura-kushanda uye kushanda kwakafara munzvimbo dzakawanda.
Zvishandiso zvePressure Sensors muIndasitiri Yemotokari
Resistive sensors midziyo inoyera kudzvanywa nekushandisa iyo musimboti wekuti kuramba kunoshanduka nekudzvanywa. Izvo zvakakosha zvema sensors aya anowanzo gadzirwa kubva kune zvinhu zvinonzwa nekumanikidza shanduko. Kana kudzvinyirirwa kwekunze kuchishandiswa kune zvinhu izvi, chimiro chavo chemuviri chinoshanduka, zvichiita kuti pave nekuchinja kwekupikisa. Shanduko iyi inogona kuyerwa nemazvo kuburikidza nedunhu uye kushandurwa kuita kuverenga kwekumanikidza. Nekuda kwechimiro chavo chakareruka uye mutengo-kushanda, resistive sensors inonyanya kufarirwa mumaindasitiri uye emotokari maapplication.
Mumagetsi ekushandisa, resistive sensors inoita basa rakakosha. Ivo vanoona shanduko yekumanikidza nekuyera shanduko mukupokana, uye kureruka kwavo uye mutengo-kushanda kunoita kuti ive chishandiso chakakosha munzvimbo dzemotokari nemaindasitiri. Semuyenzaniso, mumotokari injini manejimendi masisitimu, resistive sensors ine basa rekutarisa shanduko yedzvinyiriro muhuwandu hwekutora. Iyi data inoshandiswa neInjini Kudzora Unit (ECU) kugadzirisa chiyero chemhepo-kune-mafuta, optimize kushanda kwemafuta uye kuderedza kuburitswa. Pamusoro pekuita optimization, resistive sensors zvakare inoita basa rakakosha mukusimudzira kuchengetedzwa kwekutyaira. Iwo anoshandiswa kutarisa kudzvanywa shanduko mumasisitimu anokonzera kutumirwa kweairbag ipapo ipapo panguva yekudhumhana. Pamusoro pezvo, kunyorera kwavo kunosvika kune kugadzikana kwemotokari uye rollover kudzivirira masisitimu, vachiramba vachitarisisa system kudzvanywa kuti ive nechokwadi chekuchengetedza mota uye kugadzikana pasi pemamiriro akasiyana ekutyaira.
Kuburikidza nekushandiswa kwehunyanzvi hwematekinoroji aya, ma sensors anodzivirira haangonatsiridze mashandiro uye kugona kwemotokari asi zvakare anowedzera zvakanyanya kuchengetedza uye kunyaradza kwevatyairi. Nekufambira mberi kwetekinoroji uye kuenderera mberi kwekutsvaga mutengo-kushanda, resistive sensors icharamba ichiita basa rakakosha muindasitiri yemotokari, ichifambisa humwe kuvandudzwa mukuchengetedza uye kushanda nesimba.
Ramangwana Trends muPressure Sensors
Kubatanidzwa neInternet Yezvinhu (IoT):
Nekukurumidza kufambira mberi kweIoT, ma sensors ekumanikidza ari kuwedzera kubatanidzwa neIoT zvishandiso, zvichiita kuti kure kure kutarisa uye kuongororwa kwedata. Mudzimba dzakangwara uye maindasitiri otomatiki, chaiyo-nguva data kubva kumanikidziro sensors inogona kushandiswa kutarisa shanduko yezvakatipoteredza uye kukwidziridza mashandiro ehurongwa.
Zvishandiso Zvitsva uye Zvigadzirwa zveTekinoroji:
Kushandiswa kwezvinhu zvitsva (senananomaterials) uye matekinoroji (senge tekinoroji yeMEMS) kwaita kuti ma sensors ekumanikidza ave madiki, anyatsojeka, uye akasimba. Aya magadzirirwo haangosangana chete nezvinodiwa zveazvino maapplication asi zvakare anovhura magonhi emangwana maapplication akadai sezvishandiso zvinopfekwa uye zvakanyanya nharaunda detectors.
Ramangwana Application Tarisiro:
Pressure sensors inotarisirwa kuita basa rakakura mundima dziri kusimukira sekutarisa kwezvakatipoteredza, hutano hwehutano, uye maguta akangwara. Semuenzaniso, ma sensors ekumanikidza anogona kutarisa kukanganisa kwekushanduka kwemamiriro ekunze munzvimbo dzakakwirira, zvichipa ruzivo rwakakosha rwekutsvakurudza kwesayenzi.
Kuburikidza nekuongororwa kwakadzama uku uye zvidzidzo zvekesi, isu tinogona kuona mashandisirwo akawandisa ema sensors ekumanikidza munzvimbo dzakasiyana siyana uye kugona kwavo kwekusimudzira mune ramangwana. Nekufambira mberi kwetekinoroji uye kushandiswa kwezvinhu zvitsva, ma sensors ekumanikidza acharamba achiita basa rakakosha mumaindasitiri akasiyana, achiunza humwe hutsva nekuvandudza.
