I-walkie talkie ehamba phambili ngo-2021—exhuma umhlaba kalula
Imisakazo yezindlela ezimbili, noma i-walkie-talkies, ingenye yezindlela zokuxhumana phakathi kwezinhlangothi.Ungathembela kuzo uma insizakalo yomakhalekhukhwini imabala, iyakwazi ukuxhumana, futhi iyithuluzi elibalulekile lokuhlala ehlane noma emanzini.Kodwa indlela yokukhetha i-walkie-talkie, manje ngizoyichaza ngendlela elula ukuyiqonda.
Okuqukethwe:
A. Ezinye izinkinga lapho uthenga ama-walkie talkies
1. Kungani i-walkie-talkie ingenayo ipharamitha yebanga?

A. Ezinye izinkinga lapho uthenga ama-walkie talkies
1. Kungani i-walkie-talkie ingenayo ipharamitha yebanga?
Nakuba ibanga lokudlulisela liyinkomba yokusebenza ebalulekile ye-walkie-talkie, njengohlobo lwemishini yokuxhumana yamagagasi e-ultrashort, ibanga lokudlulisela lizothintwa amandla e-walkie-talkie, izithiyo ezizungezile, nobude.
Amandla:amandla okudlulisa iyipharamitha ebaluleke kakhulu yama-walkie-talkies.Amandla azothinta ngqo ukuzinza kwesiginali kanye nebanga lokudlulisela.Ngamagama alula, lapho amandla okukhiphayo emakhulu, ibanga lokuxhumana likhulu.
Izithiyo:Izithiyo zingathinta ibanga lokudlulisela lamasignali e-walkie-talkie, njengezakhiwo, izihlahla, njll., zonke zingamunca futhi zivimbe amaza omsakazo akhishwa ama-walkie talkies.Ngakho-ke, ukusebenzisa ama-walkie-talkies ezindaweni zasemadolobheni kuzonciphisa kakhulu ibanga lokuxhumana.
Ubude:Ukuphakama kokusetshenziswa komsakazo kunomthelela omkhulu.Lapho iphezulu indawo esetshenziswayo, yilapho isignali izodluliswa ngokude kangakanani.
2. Ingabe izinhlobo ezahlukene ze-walkie-talkie zingaxoxa zodwa?
Uhlobo lwe-walkie-talkie luhlukile, kodwa isimiso siyafana, futhi bangakwazi ukuxhumana uma nje imvamisa ifana.
3. Lingakanani ibanga lokuxhumana le-walkie-talkie?
Isibonelo, i-civil walkie talkie ngokuvamile ingaphansi kuka-5w, kufika ku-5km ezindaweni ezivulekile, kanye ne-3km ezakhiweni.
4. Ingabe ngidinga ilayisense yokusebenzisa i-walkie-talkies?
Ngokomgomo wendawo yangakini, sicela uthintane nomnyango wezokuxhumana wezwe lakini.
5. Uyini umehluko phakathi kwe-digital walkie-talkie kanye ne-analog walkie-talkie?
I-Digital walkie-talkies iyinguqulo ethuthukisiwe ye-analog walkie-talkie.Uma kuqhathaniswa ne-analog walkie-talkie yendabuko, izwi licacile, ukuzethemba kunamandla, nekhono lokudlulisa idatha lingcono.Kodwa intengo futhi iphakeme kune-analog walkie-talkie yendabuko.Uma okuqukethwe kokuxhumana okubethelwe kuyadingeka, ungakhetha ama-walkie-talkies edijithali.Ngakolunye uhlangothi, i-analog walkie-talkie yanele ukusetshenziswa okuvamile.
6. Ungalihlola kanjani izinga lokuvikela ukuphepha?
Ama-walkie-talkies amaningi amakwe ngebanga lawo elingangeni manzi nelingenazintuli, elimele i-IPXX.U-X wokuqala usho izinga elingangenwa izintuli, kanti u-X wesibili usho izinga lokungangeni kwamanzi.Isibonelo, i-IP67 isho ukuthi i-level 6 ingangenisi uthuli kanye neleveli7 ingangeni manzi.
| Ibanga lokungangeni uthuli | Ibanga elingangeni manzi | ||
| 0 | Akukho ukuvikelwa ekuthinteni nasekungeneni kwezinto | 0 | Asikho isivikelo ekungeneni kwamanzi |
| 1 | > 50 mm 2.0 ku Noma iyiphi indawo enkulu yomzimba, njengengemuva lesandla, kodwa asikho isivikelo ekuthintaneni ngamabomu nengxenye yomzimba | 1 | Amanzi aconsayo Amanzi aconsayo (amaconsi ahla aqondile) ngeke abe nomthelela olimazayo kusifanekiso uma sifakwe endaweni eqondile ku-turntable futhi sizungeziswa ngo-1 RPM. |
| 2 | > 12.5 mm 0.49 ibe Iminwe noma izinto ezifanayo | 2 | Amanzi aconsayo lapho etshekiswa ku-15° Amanzi aconsayo aqondile ngeke abe nomthelela olimazayo lapho indawo ebiyelwe itshekiswa nge-engeli engu-15° ukusuka endaweni yayo evamile.Isamba sezikhundla ezine sivivinywa phakathi kwama-eksisi amabili. |
| 3 | > 2.5 mm 0.098 in Amathuluzi, izintambo eziwugqinsi, njll. | 3 | Ukufafaza amanzi Amanzi awela njengesifutho kunoma iyiphi i-engeli efika ku-60° ukusuka mpo ngeke abe nomphumela olimazayo, kusetshenziswa noma: a) i-oscillating fixture, noma b) Isifutho somlomo onesivikelo esinokulinganisela. Isivivinyo a) senziwa imizuzu emi-5, bese siphinda isifanekiso sizungeziswa ngokuvundlile ngo-90° ngokuhlolwa kwesibili okuyimizuzu emi-5.Ukuhlolwa b) kwenziwa (kufakwe isihlangu endaweni) imizuzu emi-5 ubuncane. |
| 4 | > 1 mm 0.039 in Izintambo eziningi, izikulufu ezizacile, izintuthwane ezinkulu njll. | 4 | Ukuchaphazwa kwamanzi Ukuchaphaza kwamanzi endaweni ebiyelwe kusuka kunoma iyiphi indlela angeke kube nomphumela olimazayo, kusetshenziswa noma: a) into enyakazayo, noma b) Isifutho somlomo ongenaso isihlangu.Isivivinyo a) senziwa imizuzu eyi-10.b) yenziwa (ngaphandle kwesihlangu) imizuzu emi-5 ubuncane. |
| 5 | Kuvikelwe uthuli Ukungena kothuli akuvinjelwe ngokuphelele, kodwa akumele kungene ngobuningi okwanele ukuphazamisa ukusebenza okwanelisayo kwemishini. | 5 | Amajethi amanzi Amanzi akhiqizwa ngombhobho (6.3 mm (0.25 in)) ngokumelene nendawo ebiyelwe ukusuka kunoma iyiphi indlela angeke abe nemiphumela elimazayo. |
| 6 | Uthuli oluqinile Akukho ukungena kothuli;isivikelo esiphelele ekuthinteni (uthuli-tight).Kufanele kufakwe ivacuum.Ubude besikhathi sokuhlola bufika emahoreni angu-8 ngokususelwe ekugelezeni komoya. | 6 | Amajethi amanzi anamandla Amanzi akhiqizwa ngamajethi anamandla (12.5 mm (0.49 in)) ngokumelene nendawo ebiyelwe ukusuka kunoma iyiphi indlela angeke abe nemiphumela elimazayo. |
| 7 | Ukucwiliswa, kufika kumitha elingu-1 (3 ft 3 in) ukujula Ukungena kwamanzi ngenani eliyingozi ngeke kwenzeke uma indawo ebiyelwe icwiliswa emanzini ngaphansi kwezimo ezichaziwe zokucindezela nesikhathi (kufika kumitha elingu-1 (3 ft 3 in) lokucwiliswa emanzini). | ||
| 8 | Ukucwiliswa, imitha elingu-1 (3 ft 3 in) noma ukujula okwengeziwe Izinto ezisetshenziswayo zifanele ukucwiliswa ngokuqhubekayo emanzini ngaphansi kwezimo ezizocaciswa umenzi.Nokho, ngezinhlobo ezithile zemishini, kungasho ukuthi amanzi angangena kodwa kuphela ngendlela yokuthi angakhiqizi imiphumela eyingozi.Ukujula kokuhlolwa nobude besikhathi kulindeleke ukuthi kube kukhulu kunezimfuneko ze-IPx7, futhi eminye imiphumela yemvelo ingase yengezwe, efana nokuhamba ngebhayisikili ngaphambi kokucwiliswa emanzini. | ||
