Yuav ua li cas xaiv lub tsheb xov tooj cua? Rau cov tsheb thauj khoom, tsheb tavxij tsav tsheb
Txhua tus neeg tsav tsheb paub tias nws tseem ceeb npaum li cas kom tiv tauj nrog lub ntiaj teb sab nraud thaum mus ncig. Hmoov tsis zoo, kev sib txuas lus hauv xov tooj ntawm tes tsis rub tau zoo nyob txhua qhov chaw - nws yog txaus kom tsav deb ntawm lub nroog thiab tus naj npawb ntawm cov teeb liab tuav lub zog poob qis.
Nrov niaj hnub no GLONASS lossis GPS trackers ua rau nws tuaj yeem xa lub tswb nrov, tab sis lawv tsim nyog rau kev sib txuas lus tsuas yog hauv thaj tsam ntawm GSM tes hauj lwm.
Yog vim li cas cov neeg tsav tsheb nyiam tsheb xov tooj cua.
Qhov zoo ntawm nws cov installation yog raws li nram no:
- kev sib txuas lus yog dawb - koj tsis tas yuav them raws li tus nqi ntawm tus neeg teb xov tooj ntawm tes lossis rau pob ntawv hloov pauv ntawm GPRS;
- koj tuaj yeem yooj yim npaj cov rooj sib tham tiag tiag - tus neeg tsav tsheb tau hnov txhua tus neeg nyob hauv ib lub vojvoog ntawm 10-20 mais, tuaj yeem sib tham, tshaj tawm ntau yam ntaub ntawv, piv txwv li, hais txog cov tub ceev xwm tshaj tawm;
- ib txoj hauv kev zoo rau kev sib txuas lus rau cov tsav tsheb tavxij thiab cov neeg xa khoom;
- teeb liab zoo tsis nyob ntawm huab cua.
Yuav ua li cas xaiv lub xov tooj cua pheej yig thiab txhim khu kev qha hauv tsheb? Vodi.su yuav sim xyuas nws.
Cov yam ntxwv tseem ceeb ntawm cov xov tooj cua
Lub walkie-talkie hauv lub tsheb yuav tsum txhawb nqa Citizen's Band lossis tsuas yog CB. CB yog ib qho tshwj xeeb 27 MHz band. Tsis muaj ntawv tso cai yuav tsum tau sib txuas lus ntawm cov nthwv dej no. Raws li txoj cai, txhua lub tsheb xov tooj cua yog tsim los rau ntau zaus ntawm 26 txog 695 Hertz lossis ntau dua.
Cov yam ntxwv tseem ceeb:
- kav hlau txais xov;
- lub xub ntiag ntawm lub suab nrov txo kev ua haujlwm (AQL) - filtering extraneous cuam tshuam;
- tus naj npawb ntawm cov kab lossis kab sib txuas - 80 lossis ntau dua;
- modulation - kev hloov ntawm AM / FM zaus;
- zaus daim phiaj C thiab D - txhua daim phiaj muaj 40 raws;
- hwj chim - teeb liab propagation vojvoog;
- receiver rhiab heev;
- kev khiav hauj lwm kub.
Cia peb saib qee qhov ntawm cov kev xaiv no.
Kav hlau txais xov
Antennas tuaj nyob rau hauv peb hom mounting:
- ntawm cov hlau nplaum - lawv tau yooj yim txuas, tab sis tib lub sij hawm lawv khawb cov xim pleev xim ntawm lub ru tsev, thiab cov kav hlau txais xov hom no tsis tuaj yeem siv lub cev lub cev ua lub teeb liab amplifier, yog li cov hlau txuas ntxiv yuav tsum tau txuas. rau lub cev;
- ntawm lub mount - mounted ntawm lub bumper, qhov rooj, ntws, muab kev sib cuag nrog lub cev thiab teeb liab amplification;
- mortise - qhov kev xaiv zoo tshaj plaws, tab sis koj yuav tsum ua lub qhov hauv lub cev rau kev teeb tsa.
Cov pib tshiab feem ntau xaiv ib qho ntawm thawj ob txoj kev xaiv, thiab lawv kuj yog qhov pheej yig tshaj.
Suab nrov hluav
Ib qho txiaj ntsig zoo, yam tsis muaj koj lub taub hau yuav dhau los ua square hauv ob peb teev. Squelch suppresses lub suab nrov pib kom ntau li ntau tau, thaiv cov suab nrov nyob rau hauv lub pauses ntawm lub teeb liab txais tos.
Raws li txoj cai, txhua tus tau hnov txog li cas cov neeg tsav tsheb tavxij walkie-talkies ua haujlwm: nws nyob ntsiag to, thiab sai li sai tau thaum lub teeb liab tuaj txog, nws hnov nws thiab tus neeg xa xov lub suab tau hnov. Lub squelch pib tuaj yeem hloov kho raws li qhov xav tau.
Ntau zaus, kab sib chaws, kev hloov pauv
Qhov ntau zaus koj tuaj yeem mloog tau, qhov zoo dua. Piv txwv li, koj tuaj yeem mloog cov kev sib tham uas cov tswv ntawm vintage radiotelephones muaj.
Kev ua haujlwm ntau yog CBS, feem, nws nyob ntawm nws uas koj tuaj yeem sib txuas lus nrog lwm tus tsav tsheb lossis cov neeg xa khoom. AM / FM modulation tso cai rau koj hloov ntawm nruab nrab thiab ultra-luv nthwv dej.
Ntawm FM zaus, cov xov xwm tshwj xeeb raug faib nyob rau hauv thiab ib ncig ntawm lub nroog, piv txwv li, 15th lossis 19th channels.
Sab nraum lub nroog, cov tsheb thauj khoom ua lawv cov kev sib tham ntawm AM, cov nthwv dej zoo li no nthuav dav ntau dua, thiab yog li ntawd yuav tsum muaj lub zog tsawg dua.
Channel daim phiaj yog tshwj xeeb npaj ntau yam. Nyob rau hauv European daim phiaj, lawv xaus nyob rau hauv tsib (21, 175 Hertz), thiab nyob rau hauv Russia, nyob rau hauv xoom - 21, 275, thiab hais txog. Nws yuav yooj yim dua rau koj tshawb nrhiav. Txhua daim phiaj muaj 21 channels.
Kev tsis
Hauv qhov no, peb tab tom tham txog lub zog, kev ua haujlwm voltage, qhov kub thiab txias, kev nkag siab ntawm tus neeg txais.
Lub zog ntau dua, lub vojvoog ntau koj tuaj yeem npog. Lub zog zoo tshaj plaws yog 8-10 watts, koj lub teeb liab tuaj yeem kis tau hauv ib lub vojvoog ntawm 10-20 km. Amplifiers txog li 100 watts kuj tau muag, tab sis lawv siv ntau lub zog, thiab lawv xav tau kev tso cai.
Qhov rhiab heev yog ncaj qha ntsig txog lub kav hlau txais xov. Kev khiav hauj lwm voltage - 12 (tsheb) lossis 24 (tsheb) Volts. Ntawm kev muag khoom koj tuaj yeem nrhiav adapters rau 12/24 Volts.
Qhov kub thiab txias - ntawm qhov kub npaum li cas lub walkie-talkie yuav ua haujlwm zoo. Qhov kev ntsuas no yog qhov tseem ceeb rau cov neeg uas mus ya nyob rau sab qaum teb. Rau nruab nrab latitudes, tus yam ntxwv no tsis yog qhov tseem ceeb.
Xaiv lub chaw nres tsheb xov tooj cua
Qhov ntau hnub no yog qhov dav heev, koj tuaj yeem nrhiav cov khoom siv ntawm tus nqi ntawm plaub txhiab, txog plaub caug thiab ntau dua.
Cov ntawv luam pheej yig rau 4-5 txhiab rubles muaj tag nrho cov yam ntxwv tsim nyog:
- compact, lub teeb yuag;
- Tag nrho cov fasteners suav nrog.
- magnetic kav hlau txais xov (tej zaum yuav muag nyias);
- ua haujlwm hauv Lavxias thiab European network ntawm cov channel;
- CB.
Nws yog qhov tseeb tias cov teeb meem tuaj yeem ua rau lub suab nrov txo qis, lub zog tsis muaj zog, tsis zoo ntawm tus neeg txais kev xav. Rau lub nroog, qhov no tsis yog qhov kev xaiv zoo tshaj plaws, raws li koj tsuas yog yuav lag ntseg los ntawm kev thuam.
Ntau kim walkie-talkies yog qhov txawv los ntawm kev ua haujlwm siab, kev teeb tsa ntxiv, kev yooj yim thiab siv tau yooj yim. Lawv tau yuav, raws li txoj cai, rau kev siv tshaj lij, piv txwv li, cov neeg tsav tsheb tavxij, cov neeg ua haujlwm ntawm ntau yam kev pabcuam xa khoom, cov tsheb thauj khoom. Tus nqi ntawm cov khoom siv li no yog los ntawm 20 mus rau 40 txhiab.
