Ungakhetha kanjani umsakazo wemoto? Kwabashayeli bamaloli, abashayeli bamatekisi
Noma yimuphi umshayeli weloli uyazi ukuthi kubaluleke kangakanani ukuxhumana nabantu bangaphandle phakathi nohambo. Ngeshwa, ukuxhumana kweselula akudonsi kahle yonke indawo - kwanele ukushayela kude nedolobha futhi inani lamabha wamandla esignali liyancipha ngokuyingozi.
Okudumile namuhla i-GLONASS noma i-GPS trackers yenza kube nokwenzeka ukuthumela isignali ye-alamu, kodwa ifanele ukuxhumana kuphela endaweni yokumboza yamanethiwekhi e-GSM.
Yingakho abashayeli bekhetha imisakazo yezimoto.
Izinzuzo zokufakwa kwayo zimi kanje:
- ukuxhumana kumahhala - awudingi ukukhokha ngokwezindleko zika-opharetha weselula noma ukudluliswa kwedatha yephakethe nge-GPRS;
- ungakwazi ukuhlela kalula izingqungquthela zangempela - umshayeli weloli uzwa wonke umuntu ongaphakathi kwebanga elingamakhilomitha angu-10-20, angaqhubeka nengxoxo, abike idatha ehlukahlukene, isibonelo, mayelana nokuthunyelwe kwamaphoyisa omgwaqo;
- indlela enhle yokuxhumana nabashayeli bamatekisi kanye nama-dispatchers;
- ikhwalithi yesignali ayincikile esimweni sezulu.
Ungakhetha kanjani umsakazo ongabizi futhi onokwethenjelwa emotweni? I-Vodi.su izozama ukukuthola.
Izici eziyinhloko zeziteshi zomsakazo
I-walkie-talkie emotweni kufanele isekele i-Citizen's Band noma i-CB nje. I-CB iyibhendi ezinikele engu-27 MHz. Ayikho ilayisensi edingekayo ukuze kuxhunyanwe kulawa maza. Empeleni, yonke imisakazo yezimoto yakhelwe ibanga lokuvama ukusuka ku-26 kuya ku-695 Hertz noma ngaphezulu.
Izici ezibalulekile:
- uthi;
- ukuba khona komsebenzi wokunciphisa umsindo (AQL) - ukuhlunga ukuphazamiseka okungaphandle;
- inombolo yamashaneli noma igridi yefrikhwensi - iziteshi ezingama-80 noma ngaphezulu;
- ukuguquguquka - ukuguqulwa phakathi kwamafrikhwensi e-AM / FM;
- ama-frequency grids C no-D - igridi ngayinye iqukethe amashaneli angama-40;
- amandla - irediyasi yokusabalalisa isignali;
- ukuzwela umamukeli;
- amazinga okushisa okusebenza.
Ake sibheke ezinye zalezi zinketho.
I-Antenna
Ama-antenna eza ngezinhlobo ezintathu zokukhweza:
- kumagnet - anamathiselwe kalula, kepha ngasikhathi sinye adweba upende ophahleni, futhi lolu hlobo lwe-antenna alwenzi kube nokwenzeka ukusebenzisa umzimba wemoto njenge-amplifier yesiginali, ngakho-ke izakhi zensimbi ezengeziwe ziyadingeka ukuxhuma. emzimbeni;
- entabeni - efakwe ku-bumper, iminyango, i-drain, ukuthintana nomzimba kanye nokukhulisa isignali kunikezwa;
- mortise - inketho engcono kakhulu, kodwa kufanele wenze imbobo emzimbeni ukuze ufakwe.
Abaqalayo ngokuvamile bakhetha eyodwa yezinketho ezimbili zokuqala, futhi nazo zishibhe kakhulu.
Ukucindezela komsindo
Isici esiwusizo, ngaphandle kwalokho ikhanda lakho lizoba isikwele emahoreni ambalwa. I-Squelch icindezela umkhawulo womsindo ngangokunokwenzeka, ivimbe imisindo engaphandle ekuphumuzeni phakathi kokwamukela isignali.
Empeleni, wonke umuntu wezwa ukuthi ama-walkie-talkies abashayeli bamatekisi asebenza kanjani: uthule, futhi lapho nje isignali ifika, kuzwakala i-hers futhi kuzwakala izwi lomthumeli. Umkhawulo we-squelch ungalungiswa njengoba uthanda.
Amafrikhwensi, amagridi eziteshi, ukushintshashintsha kwezwi
Uma ungalalela amafrikhwensi amaningi, kuba ngcono. Isibonelo, ungalalela izingxoxo abanazo abanikazi bama-radiotelephones zakudala.
Uhla olusebenzayo luyi-CBS, ngokulandelana, kukulo lapho ungaxhumana khona nabanye abashayeli noma ama-dispatchers. Ukushintshashintsha kwe-AM/FM kukuvumela ukuthi ushintshe phakathi kwamagagasi aphakathi nendawo namafushane kakhulu.
Kumafrikhwensi e-FM, iziteshi ezikhethekile zabiwa ngaphakathi naseduze kwamadolobha, isibonelo, iziteshi ze-15 noma ze-19.
Ngaphandle kwedolobha, abashayeli bamaloli baqhuba izingxoxo zabo ku-AM, amagagasi anjalo anda ebangeni elikhulu, ngakho-ke kudingeka amandla amancane.
Amagridi eziteshi angamabanga alungiselelwe ngokukhethekile. Egridi yaseYurophu, ziphela ezinhlanu (21, 175 Hertz), naseRussia, ngo-zero - 21, 275, njalonjalo. Kuzoba lula kuwe ukuthi useshe. Igridi ngayinye ineziteshi ezingu-21.
Izintandokazi zezinhlelo
Kulokhu, sikhuluma ngamandla, i-voltage yokusebenza, ububanzi bokushisa, ukuzwela komtholi.
Lapho amandla engeziwe, irediyasi eyengeziwe ongayifaka. Amandla afanelekile angama-watts angu-8-10, isignali yakho ingasakazeka ngaphakathi kwendawo eyi-10-20 km. Ama-amplifiers afika ku-100 watts nawo ayathengiswa, kodwa adla amandla amaningi, futhi adinga imvume.
Ukuzwela kuhlobene ngokuqondile ne-antenna. Amandla kagesi asebenzayo - 12 (izimoto) noma ama-24 (amaloli) Volts. Uma uyathengiswa ungathola nama-adaptha angu-12/24 Volts.
Izinga lokushisa - kuliphi izinga lokushisa i-walkie-talkie izosebenza kahle. Le parameter ibalulekile kulabo abahamba ngezindiza ezifundeni ezisenyakatho. Kuma-latitudes amaphakathi, lesi sici asikona ukubaluleka kokunquma.
Ukukhetha isiteshi somsakazo
Ububanzi namuhla bubanzi kakhulu, ungathola amadivaysi ngentengo yezinkulungwane ezine, kuze kufike kumashumi amane nangaphezulu.
Amakhophi angabizi ama-ruble ayizinkulungwane ezingama-4-5 anazo zonke izici ezidingekayo:
- compact, isisindo esincane;
- Zonke izinsimbi zifakiwe.
- i-antenna kazibuthe (ingathengiswa ngokwehlukana);
- isebenza kunethiwekhi yamashaneli aseRussia naseYurophu;
- CB.
Kuyacaca ukuthi izinkinga zingaba ngokuncishiswa komsindo, amandla aphansi, ukungazweli kahle komamukeli. Edolobheni, lena akuyona inketho engcono kakhulu, njengoba uzovele ungezwa endlebeni.
Ama-walkie-talkies abiza kakhulu ahlukaniswa nokusebenza okunwetshiwe, izilungiselelo ezengeziwe, ukuba lula kanye nokusebenziseka kalula. Zithengwa, njengomthetho, ukusetshenziswa kochwepheshe, isibonelo, abashayeli bamatekisi, abasebenzi bezinsizakalo ezihlukahlukene zokulethwa, abashayeli bamaloli. Izindleko zamadivayisi anjalo zivela ku-20 kuya ku-40 ayizinkulungwane.
Iyalayisha...
