Ukulayishwa ngokweqile kanye nokweqa imingcele yezimoto zomgwaqo omkhulu kudala umonakalo omkhulu emigwaqeni futhi kubangela ingozi enkulu yezingozi zokuphepha, okuyinkinga ebucayi ikakhulukazi ezweni lakithi lapho u-70% wezigameko zokuphepha emgwaqeni ubangelwa ukugcwala kwezimoto ngokweqile kanye nokweqa imingcele. Lokhu kuholela ekulahlekelweni okuqondile kwezomnotho okucishe kube ngamabhiliyoni ama-RMB ezi-3, nokulahlekelwa ngenxa yokulayishwa ngokweqile kwezimoto kanye nokweqa imingcele emigwaqweni emikhulu engaphezu kwezigidigidi ezingama-RMB ezingama-30 ngonyaka. Ngakho-ke, kubaluleke kakhulu ukuqapha nokuqondisa izimoto ezigcwele ngokweqile emigwaqweni emikhulu.
Ukuze kulawulwe ukulayishwa kwezimoto ngokweqile ngaphandle kokuphazamisa isiminyaminya, sekuvelile uhlelo lokukala umgwaqo onguthelawayeka we-Weighting In Moving (WIM). Lolu hlelo lusebenzisa izinzwa ze-quartz ze-piezoelectric ukuze zilinganise ngokushesha isisindo semoto njengoba izimoto zidlula phezu komgwaqo ngesivinini esiphezulu (<120km/h) futhi icuphe amakhamera okuqapha ukuze athwebule.
Izinzwa ze-quartz ze-Enviko ziklanyelwe ngokukhethekile izinzwa zequartz ze-piezoelectric ezibiza izindleko eziphansi zokukala isisindo somgwaqo omkhulu nokuvikelwa kwebhuloho. Zakhiwe ngengxubevange ye-aerospace ye-aerospace ye-aerospace kanye nomshini wokunemba, lezi zinzwa zinokucindezela okuphezulu, okuqinile, ukugoba, ukugunda, nokumelana nomthwalo wokukhathala. Ngokwelashwa kokuguga, ukuzwela kwezinzwa kuhlala kuzinzile amashumi eminyaka.
Ngaphakathi egcwele insulating yokunamathisela okukhethekile okunamathiselwe, izinzwa ze-quartz ze-Enviko zigcina ingcindezi yangaphakathi ezinzile, zivimbela ngempumelelo umswakama, ngenani elijwayelekile le-insulation impedance engu-200GΩ.
Kushumekwe endaweni yomgwaqo, lapho izimoto zidlula, amasondo acindezela phansi endaweni ethwele inzwa, okubangela ukuthi amakristalu e-quartz angaphakathi kwenzwa akhiqize ukushaja ngenxa yomphumela we-piezoelectric. Ukushaja bese kukhuliswa isandisi sokushaja sangaphandle sibe isignali kagesi, elingana ngokuqondile nokucindezela okusetshenziswa kunzwa. Ngokubala isignali yokucindezela, isisindo sesondo ngalinye futhi ngaleyo ndlela isisindo esiphelele semoto singatholakala.
Isici sesilinganiso se-pressure-charge sezinzwa ze-quartz ye-piezoelectric sihlala singashintshile kungakhathaliseki izinga lokushisa, isikhathi, usayizi womthwalo, nesivinini somthwalo. Ngakho-ke, ngisho nalapho izimoto zidlula endaweni yokulinganisa ngesivinini esiphezulu, izinzwa ze-quartz zingakwazi ukugcina ukunemba kwesilinganiso esiphezulu.
Ngemuva kokuthi izinzwa ze-WIM zishunyekiwe endaweni yomgwaqo, zichayeka elangeni, emvuleni, nomfutho wesondo, okwenza ukuhlola ukwethembeka kubaluleke kakhulu.
Ukuhlolwa Kwezinga Lokushisa Nokuswakama Kokuhamba Ngebhayisikili:
Izinzwa ezinendawo ethwalayo zifakwa egunjini lokuhlola imvelo izinga lokushisa elingu-40℃ ukuya ku-85℃ nokuhlolwa kokuhamba ngebhayisikili okuswakama amahora angu-500. Ngesikhathi sokuhlolwa, i-insulation impedance yezinzwa akumele ibe ngaphansi kuka-100GΩ. Ngemuva kokuhlolwa kokuhamba ngebhayisikili lokushisa nomswakama, izinzwa zithola ukuvikeleka kokushisa nokuhlolwa komthwalo wokukhathala.
Ukuhlolwa Komthwalo Wokukhathala:
Ukuhlolwa kokukhathala komthwalo kusebenzisa ingcindezi yomjikelezo ongu-6000N kusetshenziswa inhloko yokucindezela kwensimbi enobubanzi obungu-50mm x 50mm ezindaweni ezintathu ekugcineni kwenzwa namaphakathi, nokulayisha nokuthulula kanye ngomzuzwana, okuhlanganisa imithwalo yokukhathala engu-1,000,000. Ukwehluka kokuzwela kwezikhundla zokuhlola ezilayishiwe kufanele kube ngu-<0.5%, futhi akumele kube khona umonakalo noma ukuhlukaniswa kwendawo ethwele.
Ukuvikelwa kwe-Insulation:
Ukuhlolwa kokuvikela ukufakwa kwe-insulation kubandakanya ukucwiliswa ngokugcwele kwenzwa emanzini, ukuhamba ngebhayisikili phakathi kwezinga lokushisa legumbi kanye no-80℃, nenani lobude besikhathi lokuhlola lamahora angu-1000. Kuso sonke isivivinyo, ukumelana nokufakwa kwenzwa akumele kube ngaphansi kuka-100GΩ.
I-linearity ye-piezoelectric quartz sensor signals iyinkomba ebalulekile yezinqubo zokukhiqiza nokunemba. Izinzwa ezinhle kakhulu ze-quartz ze-piezoelectric ziqinisekisa i-FSO<0.5% kulo lonke uhla. Kuzinzwa ze-WIM, iphutha lokuzwela kunoma iyiphi indawo ngobude benzwa akumele lidlule u-2%. Ngakho-ke, imishini yokuhlola ukuzwela eqinile nenembile ibalulekile ekwenzeni izinzwa.
Ijika lesici sokulayisha likala ijika lokushaja ngamandla kanye nephutha lomugqa (%FSO) phakathi nokulayisha nokuthulula ngobubanzi bekhanda lokulayisha elingu-100mm elisetshenziswa kunzwa kunoma iyiphi indawo.
Ijika lesici sesignali sokucaba silinganisa inani lokuzwela ngesikhathi sokulayisha eduze kwesiqondiso sobude benzwa (ngaphandle kwendawo ethwalayo) kusetshenziswa ikhanda lokucindezela kobubanzi obungu-50mm ngamandla angu-8000N, ngamavelu okuzwela atholakala endaweni ngayinye yokuhlola yokulayisha esetshenziselwa ukubala isignali. flatness eceleni kobude besiqondiso senzwa.
Kodwa-ke, abanye abakhiqizi basebenzisa ngamabomu ikhanda lengcindezi yokulayisha ububanzi obungu-250mm ukuze kuhlolwe isignali flatness, okulingana nesilinganiso esiphindwe ka-5 sejika lesici, okuholela ekunembeni okungamanga okungu-1%. Amasignali kuphela atholwe ngokulayisha izilinganiso kusetshenziswa ikhanda lokucindezela kobubanzi obungu-50mm angabonisa ngempela ukunemba nekhwalithi yenzwa.
