Yini kufunwe ikhebula?

Lapho uthuthukela noma ukulungisa zokuxhumana ngocingo kanye nezinye izinhlelo akulula ngaso sonke isikhathi ukuthola indawo okuvela kuyo ukuxhumana egandayiwe. Ukulandelela ikhebula - usesho indawo lapho abafundi abaphumelela ngayo zokugcina.

Ngisho uma kungabonakala ngokucacile, ngezinye izikhathi kuyadingeka ukulandelela ukuphi ye nomunye ugongolo. Ngokuvamile amadokhumenti umzila ayitholakali noma eliphansi.

Akuwona wonke umsebenzisi kuyaqondakala ikhebula ukope: ukuthi kuyini futhi kanjani ezikhathini zamanje. Ngalesi kokuhlinzwa, okulandelayo imisebenzi:

• ekutholeni indawo kanye lokudlula isignali namandla izintambo ukujula;
• ekutholeni amaphutha imigqa;
• ucwaningo endaweni ngaphambi yokwemba ukugwema ukulimala Tinsita.

Umgomo we operation kabeleiskatelya

Sesha izintambo wenza ngosizo kumadivayisi ezisebenza isimiso isiqondiso ithoni isignali generator ku izintambo futhi reception yayo, okhulisa kanye ukudlala ngama-headphone nezipikha.

Ukucinga, okuyinto oscillator nge locator isetshenziswa, ibizwa ngokuthi esebenzayo. Ukuhlangana elandelela indlela iphuzu isignali okuphakelayo agudle ezingeni ivolumu. Kudivayisi nerejista hhayi umqhubi kanye emkhakheni kagesi ezivezwa isignali eyenga therein.

Okokuqala, inzwa ne generator akhethiwe kanye nemingcele efanayo - inhlobo efanele lemigqa ukuskenwa: namapayipi komhlaba, izintambo ezakhiweni, izintambo zikagesi, iziteshi metal. Arsenal of amadivaysi atholakalayo ikhithi ze nge imisebenzi ethuthukile, phakathi lapho kukhona inqubekela phambili ukumelana nesilinganiso et al.

Inzwa angathola ensimini eyenziwe kweminye imithombo amasignali:

• Amandla imigqa;
• izintambo zocingo;
• Umsakazo inethiwekhi;
• imigqa conductive phezu 140-300 kHz.

Kulezi zimo, ungenza ngaphandle generator, lapho search wenziwa ikumodi yekwentiwa.

Kwemigomo isignali ugesi

Amapharamitha eziyinhloko amandla kanye nokuvama isignali eyenga, okungase esikukhompiyutha njalo noma njengoba multiple (kufika ku ezine) Inani 0,2-130 kHz. Esiginali sisetshenziswa ngetindlela letehlukene:

• uxhumano ngqo babashayeli esebenzisa Ukugunda;
• esehlanganise ingaphandle ngocingo exhasa noma isiqeshana ngaphandle kokuphula igobolondo (ezindaweni ezifinyelelekayo);
• ngaphandle ikhebula antenna endaweni komhlaba.

Ngokuvamile, ikhebula ukope kwenziwa uma kuvaliwe. Ngokuxhuma ngqo ezingeni isignali etholwe eliphezulu. Abanye onobuhle angathola umugqa ngaphansi voltage. Kulokhu, ukuxhumana ngqo akunakwenzeka. Ukuqeda nokugxambukela izintambo zikagesi, asetshenziselwa izihlungi, hhayi odlulayo imvamisa 50 Hz.

A kusimo ukusetshenziswa exhasa isignali antenna nokukhomba bonke Kwenzekani izintambo eduze. Nokho, lula kokusebenzisa indlela zinkulu yokuntula zayo. ke livame ukusetshenziswa ezindaweni lapho kuxhumana ngqo namatheminali akunakwenzeka. generator Coverage ulinganiselwe futhi ngezinye izikhathi kuba nesidingo ukwenza kube nokuhlobana izikhathi ezimbalwa kuze kube sekupheleni ithrekhi.

Ngaphezu kwalokho, i-antenna ngenye indlela exhasa isetshenziswa ukuthola indlela ukuxhumana intersecting emgqeni lamcoka Transmitter. Ngenxa yale njongo, abamukelayo sishukumiseleka eduze ikhebula 2 abantu esifundeni 20 m.

Ngaphezu antenna esetshenziswa namanye amadivayisi exhasa elihlangana okuyinto asidingi uxhumeke babashayeli. Uma lokhu isignali lisetshenziswa ikhebula eyodwa kuphela.

ukukhetha izinsimbi

Uma ukuthenga Kufanele ukhethe idivayisi kuyafaneleka kakhulu uhlobo oluthile lomsebenzi. I element eziyisisekelo uphenyo exhasa kuyinto inzwa, antenna (isiswebhu noma kazibuthe) we elihlangene yedivaysi noma uthintane kudivayisi. Ngaphezu kwalokho inkomba ezwakalayo ezibukwayo isetshenziswa bakwazi ukusebenza ngaphansi khona umsindo. Izilawuli ukuzwela asethwe ku iphenya.

onobuhle Special ziyatholakala ewachitha emoyeni futhi coaxial amakhebuli. Lapho uthenga umkhiqizo kumele ayejwayele imiyalelo, lapho inqubo yesicelo kuchazwa ngokuningiliziwe.

Ukope ikhebula imigqa

Okusatshalalisiwe locators komhlaba lunye sivumele ukuthola izintambo wabeka emgodini ovulekile noma iziteshi a ka 2 m ukujula. Lezi imisebenzi kungafaka ekutholeni indawo kanye kwe-circuit eluka ukujula noma abahlala emhlabeni. Amadivayisi esetshenziswa ezihlola komhlaba noma izakhiwo.

amakhebuli Ilandelela ezakhiweni ezenziwe amadivayisi jikelele nge ukusebenza okugcwele. Ngosizo lwabo, ungathola umqhubi ngaphansi usimende, i-panel ku sebefaka ukhonkolo kanye ophahleni imisiwe. Esiginali ihlinzekwa kuclamp exhasa ukuthola at ibanga 1.5 km. It is kahle neyaziwayo latimviwa, uma sakhiwa amaza ezimbili wasuthisa yanjalo. Ukuze yenza antenna izintambo ubambe livuliwe noma livaliwe phezu umthwalo asindayo. Ukuze ukuthola ikhebula ikhoyili babashayeli yayo kazibuthe noma izikhindi yonkana ongaphakeme ukumelana Resistor.

Nokuxhumana Ukucinga Izici

Ikhebula kufunwe kudinga ukuthuthukiswa kwamakhono ezithile ukuthola indawo evulekile noma elifushane wahlala. Ngokulungisa nozwela probe kumele kwenziwe ku ugongolo isiginali namandla. Uma Umbono wakhe sokuzwa akusebenzi njalo ezindaweni ezinomsindo, ungasebenzisa inkomba ezibukwayo.

Lapho ukuhlanekezela kazibuthe kusukela eseduze babashayeli isinyathelo kwenzwa kungase kuhluke izilinganiso okuphindaphindiwe. Inani olungisiwe wathola njengoba i value okulinganiselwa ku.

Hlola ukwakheka ithrekhi ukujula at amabanga ehlukene emhlabeni. Ngakho amanani etholwe kufanele ihluke ngu isamba ukunyakazisa ukuba kwenziwe uphenyo.

trace izinhlelo

Amadivayisi ekusesheni lemigqa komhlaba emkhathini wezulu kuzomele sifake isethi egcwele imishini. Isibonelo salokhu i-kit ezihlola 132j ikhebula CTS sizibone namabhuzu izintambo futhi izintambo zikathelefoni.

Uhlelo isetshenziswa ukucinga imigqa komhlaba emkhathini wezulu futhi ukuthola amaphutha kuyo.

Izibuyekezo ze-ithuluzi kufunwe CTS 132j Ikhebula esiguqukayo: ngezinye izikhathi kuyadingeka ukuthenga izesekeli ezengeziwe, okuyinto ezibizayo. Kubalulekile ukukhetha isevisi ofanele kakhulu.

Test ikhithi 701K

Ikhebula isethi ukope isetshenziswa ukucinga sezintambo emgqeni noma ezithelo, kwencazelo amakhefu nelezifunda iDemo.

Izakhi eziyinhloko generator ithoni bese uphenyo exhasa. Idivayisi isebenza nanoma iyiphi wiring: izintambo olulodwa, ngazimbili nesisontekile, izintambo coaxial. Kube ezwakalayo futhi ezibukwayo isignali inkomba. idivayisi yesimanje isethwe 711K, lapho wanezela 3 imisindo.

Kit trace Tempo CTS 132j ikhebula

Lesi simiso sihlanganisa ithoni generator ne ukushintshashintsha imvamisa isignali isicelo. Ukuthola amandla kazibuthe ikhoyili sisetshenziswa, futhi ensimini kagesi - Uphenyo exhasa. Esimweni sokuqala abanamandla isignali eyamukelayo wesifunda unikezwa phezu ekupheleni distal umbhangqwana, kanti eyesibili - ivuliwe. Ukuba udonga lwangaphandle ucwecwe ivikela emkhakheni kagesi, kodwa kazibuthe Kutholwe kalula. Lapho kufunwe isignali ikhebula kungenzeka enikeziwe ngokusebenzisa eluka ukuzivikela. Isethi yakhelwe ekutholeni ngababili ukuvalwa, usesho uqhutshwa emigceni futhi ukusatshalaliswa amakhabethe, uzingela izifunda esifushane futhi amakhefu.

Setha kufunwe IntelliTone

Isethi yakhelwe ukulandela ngomkhondo nendawo izintambo ekuxhumaneni asebenzayo. Generation of amasignali digital Ikhipha izitshengiselo isiqondiso nezingahlobene nendaba inikeza sokunquma olufanele wahlala izinyanda inquma zamehlo. Kungenzeka futhi ukuba Analog.

Nisondeze trace MT 8200 ikhebula 60A

Uhlelo kwenza kube nokwenzeka ukuba ukucinga ifoni, ikhebula coaxial, pair wasonta, ezinye izinhlobo zokuvikela kanye ithelevishini. Futhi, kukhona ukusetshenziswa amasignali digital, okuyinto ukunciphisa ithonya ukuphazamiseka.

Ukucinga optic ikhebula

Fibre optic ikhebula lungaba izakhi metallic. Thina kufanele bawasebenzisele ngokufanayo wire isikrini ezivamile. Landzelela ikhebula optical ixhunywe igobolondo generator ensimbini yinoma yimuphi indlela ezaziwayo ke kungenzeka ukucinga ngokusebenzisa i-probe.

Uma ikhebula ayiqukethe izakhi metallic, uphawu lwakhe phakathi nokufaka. Ukuze wenze lokhu, phezu ikhebula setha wesifunda resonant ka inductors futhi capacitors. Ngakho ngokuthi yokwenziwa umaka ikhebula, okuyinto akudingi amandla, uthola futhi ibonisa isiginali kusuka Lidlulisela. Ngakho indawo indawo umugqa.

isiphetho

Ukope ikuvumela ukuba zilawule indlela nendawo kufihlwe izinto enwetshiwe, ikakhulukazi - amakhebuli. Kukhona ebaluleke ukulungiselelwa lesifanele ivolumu ezingeni on osidluliselayo kanye umamukeli. Ngokukhethekile ukhangwa esikhundleni izinguquko zalo ngokuzumayo. Lokhu kungaba nokugxambukela metal izingxenye komhlaba amagatsha ekwakhekeni, ekushintsheni isiqondiso sokuphela ikhebula, ushintsho ukujula, ukubukeka eduze parallel ahlelwe babashayeli.
