Inzwa yethrafikhi ye-Piezoelectric ye-AVC (Ukuhlukaniswa Kwemoto Okuzenzakalelayo)
Incazelo emfushane:
Inzwa yethrafikhi ehlakaniphile ye-CET8311 yakhelwe ukufakwa unomphela noma wesikhashana emgwaqeni noma ngaphansi komgwaqo ukuze kuqoqwe idatha yethrafikhi. Isakhiwo esiyingqayizivele senzwa sivumela ukuthi ifakwe ngqo ngaphansi komgwaqo ngendlela eguquguqukayo futhi ngaleyo ndlela ihambisane ne-contour yomgwaqo. Isakhiwo esiyisicaba senzwa simelana nomsindo womgwaqo obangelwa ukugotshwa komgwaqo, imizila eseduze, namagagasi agobile asondela emotweni. Ukusika okuncane ku-pavement kunciphisa umonakalo endaweni yomgwaqo, kwandisa isivinini sokufaka, futhi kunciphisa inani le-grout elidingekayo ukuze kufakwe.

Isingeniso
Inzwa yethrafikhi ehlakaniphile ye-CET8311 yakhelwe ukufakwa unomphela noma wesikhashana emgwaqeni noma ngaphansi komgwaqo ukuze kuqoqwe idatha yethrafikhi. Isakhiwo esiyingqayizivele senzwa sivumela ukuthi ifakwe ngqo ngaphansi komgwaqo ngendlela eguquguqukayo futhi ngaleyo ndlela ihambisane ne-contour yomgwaqo. Isakhiwo esiyisicaba senzwa simelana nomsindo womgwaqo obangelwa ukugotshwa komgwaqo, imizila eseduze, namagagasi agobile asondela emotweni. Ukusika okuncane ku-pavement kunciphisa umonakalo endaweni yomgwaqo, kwandisa isivinini sokufaka, futhi kunciphisa inani le-grout elidingekayo ukuze kufakwe.
Inzuzo yenzwa yethrafikhi ehlakaniphile ye-CET8311 ukuthi ingathola idatha enembile neqondile, njengesignali enembile yesivinini, isignali yokuqalisa kanye nolwazi lokuhlukanisa. Ingakwazi impendulo yezibalo zolwazi lwethrafikhi isikhathi eside, ngokusebenza okuhle, ukwethembeka okuphezulu nokufaka kalula. Ukusebenza kwezindleko eziphezulu, okusetshenziswa kakhulu ekutholeni inombolo ye-asi, i-wheelbase, ukuqapha isivinini semoto, ukuhlukaniswa kwezimoto, isisindo esiguqukayo nezinye izindawo zethrafikhi.

Ukulungiselela ukufakwa
Ukukhetha kwesigaba somgwaqo:
a) Isidingo semishini yokukala: Ukuzinza nokwethembeka isikhathi eside
b)Imfuneko ku-roadbed: Ukuqina
Indlela yokufaka
5.1 Isikhala sokusika:
5.2 Izinyathelo ezihlanzekile futhi zomile
I-1, Ukuqinisekisa ukuthi izinto zokubumba zingahlanganiswa kahle nomgwaqo ngemuva kokugcwalisa, indawo yokufaka kufanele igezwe ngesicoci sokucindezela okuphezulu, futhi ingaphezulu le-groove kufanele ligezwe ngebhulashi lensimbi, futhi air compressor/ high pressure air gun noma blower isetshenziswa ngemva kokuhlanza ukomisa amanzi.
2, Ngemva kokuba udoti usuhlanziwe, umlotha ontantayo endaweni yokwakha kufanele uhlanzwe nawo. Uma kukhona amanzi aqoqiwe noma umswakama osobala obonakalayo, sebenzisa i-air compressor (isibhamu somoya ocindezelayo) noma i-blower ukuze uyomise.
3, Ngemva kokuqedwa kokuhlanza, i-tape yokuvala (ububanzi obukhulu kuno-50mm) isetshenziswa
endaweni yomgwaqo ezungeze inotshi ukuvimbela ukungcoliswa kwe-grout.
5.3 Ukuhlolwa kwangaphambi kokufakwa
1, Umthamo wokuhlola: Sebenzisa i-multi-meter yedijithali ukukala ingqikithi yamandla enzwa ngekhebula elinamathiselwe. Inani elilinganisiwe kufanele libe phakathi kobubanzi obucaciswe inzwa yobude obuhambisanayo neshidi ledatha yekhebula. Ibanga lomhloli ngokuvamile lisethelwa ku-20nF. I-probe ebomvu ixhunywe kumgogodla wekhebula, futhi i-probe emnyama ixhunywe kwisihlangu sangaphandle. Qaphela ukuthi akufanele ubambe zombili iziphetho zokuxhuma ngesikhathi esisodwa.
2, Ukumelana nokuhlolwa: Kala ukumelana kuzo zombili iziphetho zenzwa nge-digital multi-meter. Imitha kufanele isethelwe ku-20MΩ. Ngalesi sikhathi, ukufundwa ewashini kufanele kudlule u-20MΩ, ngokuvamile okhonjwa ngokuthi “1”.
5.4 Lungisa ubakaki okhwezwayo
5.5 Hlanganisa i-grout
Qaphela: Sicela ufunde imiyalelo ye-grout ngokucophelela ngaphambi kokuxuba.
I-1) Vula i-potting grout, ngokuya ngesivinini sokugcwalisa kanye nesilinganiso esidingekayo, ingenziwa ngamanani amancane kodwa izikhathi ezimbalwa ukuze ugweme imfucuza.
2) Lungiselela inani elifanele le-potting grout ngokwesilinganiso esishiwo, bese ugovuza ngokulinganayo ngesando sikagesi esishukumisayo (cishe imizuzu emi-2).
3)Ngemva kokulungiselela, sicela usebenzise phakathi nemizuzu engama-30 ukugwema ukuqina ebhakedeni.
5.6Izinyathelo zokuqala zokugcwalisa i-grout
1) Thela i-grout ngokulinganayo ngobude be-groove.
2)Uma ugcwalisa, imbobo yokukhipha amanzi ingakhiwa ngesandla ukuze kube lula ukulawula isivinini nokuqondisa ngesikhathi sokuthulula. Ukuze wonge isikhathi namandla omzimba, ingathululwa ngeziqukathi zomthamo ezincane, okulungele abantu abaningi ukuthi basebenze ngesikhathi esisodwa.
3) Ukugcwalisa kokuqala kufanele kube izikhala ezigcwele ngokugcwele, futhi kwenze indawo engaphezulu ye-grout ibe phezulu kancane kunomgwaqo ogandayiwe.
4) Londoloza isikhathi ngangokunokwenzeka, ngaphandle kwalokho i-grout izoqina (lo mkhiqizo unesikhathi sokwelapha esivamile samahora angu-1 kuya kwangu-2).
5.7 Izinyathelo zokugcwalisa i-grout yesibili
Ngemuva kokuthi i-grouting yokuqala ilaphekile, bheka ubuso be-grout. Uma ingaphezulu liphansi kunomgwaqo noma indawo iboshiwe, hlanganisa kabusha i-grout (bheka isinyathelo 5.5) bese wenza ukugcwalisa kwesibili.
Ukugcwaliswa kwesibili kufanele kuqinisekise ukuthi ubuso be-grout bungaphezu kancane komgwaqo.
5.8Ukugaya ngaphezulu
Ngemva kokufaka isinyathelo 5.7 siqedwa isigamu sehora, futhi i-grout iqala ukuqina, iklebhule amateyipu ezinhlangothini zezikhala.
Ngemva kokufaka isinyathelo 5.7 siqedwa ihora elingu-1, futhi i-grout iqiniswe ngokuphelele, gaya i-
i-grout nge-grinder ye-engeli ukuze iyenze iguqe nomgwaqo.
5.9 Ukuhlanza endaweni kanye nokuhlolwa kwangemuva kokufakwa
1) Hlanza izinsalela ze-grout nezinye izinsalela.
2) Ukuhlola ngemva kokufaka:
(1)Amandla okuhlola: sebenzisa imitha eningi yedijithali ukukala ingqikithi yamandla enzwa ngekhebula elinamathiselwe. Inani elilinganisiwe kufanele libe phakathi kobubanzi obucaciswe inzwa yobude obuhambisanayo neshidi ledatha yekhebula. Ibanga lomhloli ngokuvamile lisethelwa ku-20nF. I-probe ebomvu ixhunywe kumgogodla wekhebula, futhi i-probe emnyama ixhunywe kwisihlangu sangaphandle. Qaphela ukuthi ungabambi iziphetho ezimbili zokuxhuma ngesikhathi esisodwa.
(2)Ukumelana nokuhlola: sebenzisa imitha eminingi yedijithali ukukala ukumelana kwenzwa. Imitha kufanele isethelwe ku-20MΩ. Ngalesi sikhathi, ukufundwa ewashini kufanele kudlule u-20MΩ, ngokuvamile okhonjwa ngokuthi “1”.
(3) Ukuhlolwa kokulayisha ngaphambilini: ngemva kokuhlanzwa kwendawo yokufaka, xhuma okukhiphayo kwenzwa ku-oscilloscope. Isimo esijwayelekile se-oscilloscope yile: I-Voltage 200mV/div, Isikhathi 50ms/div. Ukuze uthole isignali evumayo, i-voltage ye-trigger isethelwe cishe ku-50mV. I-waveform evamile yeloli nemoto iqoqwa njenge-waveform yokuhlola ukulayisha kuqala, bese i-waveform yokuhlola igcinwa futhi ikopishwe ukuze iphrintwe, futhi ilondolozwe unaphakade. Okukhiphayo kwenzwa kuncike endleleni yokukhweza, ubude benzwa, ubude bekhebula nezinto zokubumba ezisetshenzisiwe. Uma ukuhlolwa kokulayisha kuqala kujwayelekile, ukufakwa kuqediwe.
3) Ukukhishwa kwethrafikhi: amazwibela: Ithrafikhi ingadedelwa kuphela uma imbiza isilaphe ngokuphelele (cishe amahora angu-2-3 ngemva kokugcwalisa okokugcina). Uma ithrafikhi ikhishwa lapho i-potting material ingalashwa ngokuphelele, izolimaza ukufakwa futhi ibangele inzwa ukuthi ihluleke ngaphambi kwesikhathi.
Layisha kuqala i-waveform yokuhlola
