【Ukuthuthukiswa Komkhiqizo Wokuklanywa Kwemboni】 Impahla yokuhlonza ifrikhwensi yomsakazo wemoto entsha
Isingeniso Somkhiqizo
Isizukulwane esisha sohlelo lokuhlonza ifrikhwensi yomsakazo wemoto olususelwe kubuchwepheshe bokuxhumana befrikhwensi yomsakazo webanga elifushane.Lolu hlelo luwuhlelo lokuhlonza okungenantambo olusekelwe kumgomo wokuxhumana kwedijithali nokusebenzisa i-transceiver ye-UHF ehlanganisiwe ye-single-narrowband.Umgomo oyisisekelo wokusebenza nombono womklamo wehadiwe wohlelo lokuhlonza ifrikhwensi yomsakazo uchaziwe, futhi kunikezwe ishadi lokugeleza lohlelo lomklamo wohlelo.Ngokombono wokusetshenziswa kwamandla okuphansi, ukuhlonza okuphumelelayo nokusebenza, umaka we-RFID ofanele imoto uyaklanywa.Ngaphansi kwesimo sezimo zomgwaqo eziyinkimbinkimbi (umgwaqo omatasatasa), ingakwazi ukuqashelwa ngempumelelo phakathi kwama-300m, futhi ngaphansi kwesimo sebanga lokubona, ingafinyelela ukuqashelwa okusebenzayo phakathi kwama-500m.
Isibonisi somkhiqizo
Isizukulwane esisha sohlelo lokuhlonza ifrikhwensi yomsakazo wemoto olususelwe kubuchwepheshe bokuxhumana befrikhwensi yomsakazo webanga elifushane.Lolu hlelo luqukethe iyunithi yemoto yokuxhumana engenantambo yebanga elifushane kanye nesistimu yesiteshi eyisisekelo ukwakha isistimu yokuhlonza okungenantambo ye-point-to-multipoint, engasetshenziselwa ukuhlonza imoto kanye neziqondiso ezihlakaniphile ngaphakathi kokumbozwa kwesiteshi sesisekelo.
Ihadiwe yesistimu yakhiwe ngokuyinhloko ingxenye yokulawula, ingxenye ye-RF kanye nengxenye yohlelo lokusebenza enwetshiwe yangaphandle.Nge-MCU yamandla aphansi njengeyunithi yokulawula, i-transceiver ye-single-chip ye-narrowband ye-UHF ehlanganisiwe, i-antenna yedizayini eyakhelwe ngaphakathi, namandla ebhethri e-photovoltaic athuthukisiwe, qaphela ukuhlanganiswa okuphezulu kwebanga elifushane lokuhlonza i-wireless radio frequency terminal (OBU).Ngokwezidingo zangempela zohlelo lokusebenza, amasekhethi amaningi e-analog, amasekhethi edijithali nama-microprocessors ahlanganiswe ku-chip eyodwa ukuze anikeze isisombululo "se-chip eyodwa".
Inzuzo Yomkhiqizo
Ingxenye yokuphakelwa kwamandla yesistimu inikwa amandla inhlanganisela yebhethri ye-photovoltaic njengomthombo wamandla wansuku zonke kanye nebhethri ye-lithium-ion njengebhethri eliyisipele.Amandla elanga asetshenziselwa ukushaja ibhethri yokugcina amandla ngaphansi kwesimo sokukhanya okuhle, futhi inani elithile lesikhathi sokukhanya lingahlangabezana nezidingo zomsebenzi zansuku zonke ze-OBU, enweba kakhulu impilo yesevisi yebhethri eliyisipele kanye nempilo yokusebenza. kwe OBU.
Uhlelo lusebenzisa ukwakheka kwemodular futhi lubhalwe ngolimi C.Ikakhulukazi yakhiwe izingxenye ezine: imojula yohlelo oluyinhloko, imojula yohlelo lokuxhumana, imojula ye-peripheral circuit processing, i-interrupt and memory module.Inqubo yokuxhumana phakathi kwe-OBU ne-BSS ihlukaniswe ngezinyathelo ezintathu: ukusungula izixhumanisi, ukushintshisana ngolwazi nokukhipha izixhumanisi.
I-chip ye-RF ididiyelwe kakhulu, engafinyelela usayizi omncane, ukusetshenziswa kwamandla okuphansi kanye nokufakwa kalula, futhi iyasebenza ekwakhiweni kwesistimu yokuqapha nokuqapha yamahhala yokupaka izimoto.
