Ukugcinwa kwesandisi-lizwi semizi-mveliso kubalulekile kuba ukuqondwa kwentetho kudla ngokuba yeyona nto iphambili ekujoliswe kuyo, hayi imveliso eluhlaza. I-IEC 60268-16 isetyenziswa kakhulu ukuvavanya umgangatho wokudluliselwa kwentetho, ngelixa i-IEC 60529 ichaza amanqanaba okhuseleko oluvaliweyo afana ne-IP65 kunye ne-IP66 yokumelana nothuli namanzi; ezo zilinganiso zinceda ekuchazeni isizathu sokuba ezinye iiyunithi zesithethi zefektri ziphile iminyaka emininzi ngaphandle ngelixa ezinye zisilela kwangethuba. Kwindawo yokuvelisa enengxolo, nenkqubo yesandisi-lizwi enamandla inokwenza umsebenzi ongaphantsi ukuba iigrilles ziyavaleka, zivale ubudala, okanye useto lwe-amplifier luyahamba. Ukuba iwebhusayithi yakho isebenzisaizixhobo zonxibelelwano lwemizi-mveliso, izixhobo ezikhusela imozuluokanyeizixhobo zendawo enobungozi, ingqiqo efanayo yokugcinwa iyasebenza: khusela indawo ebiyelweyo, qinisekisa indlela yesignali, kwaye ubhale phantsi uhlolo ngalunye.

Yintoni ekhusela ngokwenene ukugcinwa kwesandisi-lizwi semizi-mveliso kwinkqubo yesandisi-lizwi

Ukugcinwa kwesandisi-lizwi semizi-mveliso kukhusela izinto ezintathu: ukuqondwa, ixesha lokusebenza, kunye nokuthobela imithetho.

Enyanisweni, amaqela amaninzi ezityalo aphawula ingxaki kuphela emva kokuba imiyalezo ibe nzima ukuyiqonda, kodwa ngelo xesha unobangela uhlala uqokelelana. Ukwanda kothuli kunciphisa amandla okukhupha isandi, iiterminals ezidlakadlaka zongeza ukumelana, kwaye ukungena kwamanzi kutshintsha indlela aqhuba ngayo. Isithethi sasefektri esibonakala siphelele sisenokungacaci ukuba i-diaphragm idiniwe okanye i-transformer ishushu kakhulu.

Kwiindawo zoshishino, injongo yokugcinwa kwento kufuneka ilinganiswe. Ukudluliselwa kwentetho kudla ngokuvavanywa ngeendlela ezichanekileyo, kwaye i-IEC 60268-16 ibonelela ngesakhelo esimiselweyo sovavanyo lwesalathisi sokudluliselwa kwentetho. Oko kubalulekile kuba umyalezo omkhulu ogqwethekileyo unokuba luncedo kangako kunowothuleyo kodwa ocacileyo. Kunxibelelwano olungxamisekileyo, ukucaca konga ixesha, kunciphisa ukudideka, kwaye kunciphisa amathuba okuphazamisa abasebenzi ngexesha lokuphuma.

Kukwakho ne-engile yeendleko zokusebenza. Ngokwesikhokelo se-US OSHA, unxibelelwano olungxamisekileyo kufuneka luthembeke ngokwaneleyo ukuxhasa ukufuduka okukhuselekileyo kunye nokucwangciswa kwempendulo kwiindawo zomsebenzi, yiyo loo nto iirekhodi zokuhlola kunye nokuhlolwa kokusebenza kungeyona into yokuzikhethela kwiindawo ezilawulwayo. Kumaqela obunjineli, ukugcinwa kwempahla yinxalenye yolawulo lomngcipheko, kungekhona umsebenzi wobuhle.

Iindlela zokungaphumeleli kwesandisi-lizwi semizi-mveliso kunye nesithethi semizi-mveliso omele uzilindele

Uninzi lweengxaki zesandisi-lizwi kwimizi-mveliso ziyaxelwa kwangaphambili ukuba imeko-bume iyaziwa.

Ukufuma okuphezulu, isitshizi setyuwa, uthuli, kunye nokungcangcazela zezona zinto zixinzelela kakhulu kwiindawo zokubeka izithethi zasefektri. Ukuba indawo ikufutshane neentambo zokuhlamba, izibuko zaselwandle, iindawo zokucubungula ukutya, okanye iindawo zokulayisha zangaphandle, indawo ebiyelweyo kunye neendawo zokudibanisa ziba ziindawo zokuqala ezibuthathaka. Ikhonkco eliqhelekileyo lokusilela liqala ngokudilizwa kwesitywina, emva koko kungene ukufuma, emva koko kufakwe i-oxidation, emva koko kuvele isandi esingenamsebenzi okanye ukusilela komqhubi ngokupheleleyo.

Ukungcangcazela yenye into efihlakeleyo. Kwimizi-mveliso, ukungcangcazela okuphindaphindiweyo koomatshini kunokukhulula izibophelelo kunye neebhloko zesiphelo ngokuhamba kwexesha. Yiyo loo nto isithethi sefektri esifakwe kwifreyimu yentsimbi kufuneka sihlolwe ukuba asinaso na i-torque yesibiyeli kunye nokukhululeka koxinzelelo lwentambo, ingakumbi xa inkqubo yesandisi-lizwi ifakwe kufutshane neepress, iiconveyor, okanye oomatshini abanzima.

Ukujikeleza kobushushu nako kubalulekile. Izithethi zangaphandle nezingaphandle zinokwanda kwaye zinciphe imihla ngemihla, zisenza buthathaka izivalo kancinci kancinci kwaye zenze izithuba ezincinci ezivumela uthuli kunye nokufuma ukuba kungene. Kwezo meko, impendulo echanekileyo yokulungisa ayikokucoca nje kuphela; kukuphinda kuqinisekiswe ubume begumbi kunye nokutshintshwa kwee-gaskets ezindala ngaphambi kokuba zenzekele.

Indlela yokugcina inkqubo yesandisi-lizwi inyathelo ngenyathelo

Inkqubo yokuhlola ecwangcisiweyo yeyona ndlela isebenzayo yokugcina inethiwekhi yesandisi-lizwi semizi-mveliso ithembekile.

1. Qala ngokujonga ngamehlo iindawo ezibiyelweyo, iigrilles, iibrakethi kunye neentambo zentsimbi.
2. Jonga ukuba akukho mifantu, umhlwa, amabala amanzi, umonakalo we-UV, kunye nezixhobo ezingekhoyo.
3. Qinisekisa imeko ye-amplifier, iilebhile zezoni, kunye nazo naziphi na izalathisi zempazamo kwisilawuli.
4. Dlala isaziso sovavanyo uze umamele ukugqwetheka, ukurhawuzelela, okanye ukugubungela okungalinganiyo.
5. Linganisa isiphumo kwiindawo ezibalulekileyo uze usithelekise nokufundwa kwesiseko.
6. Bhala phantsi umhla wokuhlolwa, indawo echaphazelekayo, kunye namanyathelo okulungisa.

Amaqela okulungisa angcono ahlala esebenza ngokwendawo. Oko kuthetha ukuba isandisi-lizwi ngasinye semizi-mveliso sibotshelelwe kwindawo ethile, injongo, kunye noluhlu lokusebenza olwamkelekileyo. Umzekelo, isithethi somgangatho wemveliso sinokwamkeleka kwiprofayili yoxinzelelo lwesandi eyahlukileyo kunesithethi sekhorido kuba ingxolo yangasemva ayifani kuyo yonke indawo. Le ndlela esekelwe kwindawo yenza ukusombulula iingxaki kube lula kwaye inceda ekuthinteleni ukutshintshwa okungeyomfuneko.

Ukucoca kufuneka kuqatshelwe. Igrille yesipikha sefektri kufuneka icocwe ngeendlela ezihambelana nezinto ezivalekileyo kunye nomgangatho we-IP. Amanzi anoxinzelelo oluphezulu akufuneki asetyenziswe ngaphandle kokuba uyilo lwemveliso luyixhasa ngokucacileyo. Endaweni yoko, sebenzisa iindlela zokucoca ezinomngcipheko omncinci ezisusa uthuli, inkungu yeoyile, kunye nentsalela yetyuwa ngaphandle kokunyanzela ukungcola endlwini.

Ngoku kaI-ISO 7240-16, iinkqubo ze-alamu yelizwi kulindeleke ukuba zixhase unxibelelwano oluthembekileyo olungxamisekileyo, kwaye olo lindelo luchaphazela indlela yokugcinwa okucwangcisiweyo. Ukuba inkqubo yesandisi-lizwi isetyenziselwa ukufuduka okanye izilumkiso zezityalo, amaxesha ovavanyo kufuneka abe mancinci kuneepeji zesiqhelo.

Imigangatho ebalulekileyo kwisandisi-lizwi semizi-mveliso kunye nokhathalelo lwesithethi sefektri

Imigangatho inika amaqela olondolozo ulwimi olufanayo lokuhlola nokwamkela.

I-IEC 60529 ichaza amanqanaba okhuseleko olunikezelwa ziindawo ezivalekileyo, kuquka amanqaku aqhelekileyo afana ne-IP65 kunye ne-IP66. Kwisithethi sasefektri esifakwe kwiindawo ezinothuli okanye ezimanzi, olo luhlu aluyonto nje yekhathalogu; luphawu lokugcinwa. Ukuba amanzi okanye uthuli lungena kwindawo evalekileyo, isixhobo sisenokuvelisa isandi, kodwa sele singaphandle kwemeko yaso yokusebenza.

I-IEC 60268-16 ibalulekile kuba ijongana nomgangatho wokudluliselwa kwentetho. Kwi-industrial paging, imiyalelo yongxamiseko, kunye nezibhengezo ze-alamu, ukuqondakala yeyona KPI yokwenyani. Inkqubo enomsindo kodwa engacacanga inokucothisa ukuphuma okanye ibangele imiyalelo engaphendulwanga, ingakumbi kwiindawo ezinengxolo apho ingxolo yangasemva inokudlula i-85 dB kwezinye iindawo ngokwemigangatho yokulondolozwa kokuva ye-OSHA.

Kwindlela yokufaka kunye nokugcina amaxwebhu, amaqela amaninzi axhomekeke kwiirekhodi zovavanyo ezicwangcisiweyo kunye neenkqubo zokwamkelwa kwendawo. Ngokwenyani, oku kuthetha ukurekhoda uhlobo lwesithethi, itephu yombane, indawo yokugubungela, ukuphakama kokuxhoma, kunye neziphumo zovavanyo. Loo maxwebhu yiyo eyenza ukugcinwa kamva kube yimpumelelo.

Ukukhetha imveliso, kunceda ukuthelekisa iintsapho zezixhobo ngokuqina kunye nenkonzo. Ukuba indawo yakho iyanda, unokufuna umxube weizixhobo zonxibelelwano lwe-analog, Izixhobo ezisekelwe kwi-IPkunyeiiyunithi zonxibelelwano olungxamisekileyo. Le ndlela ifanayo iyasebenza ekugcinweni kwesithethi: misela umgangatho apho kunokwenzeka khona, kodwa ubhale phantsi apho iintlobo zezixhobo zahlukile khona.

Indlela yokusombulula iingxaki zesandisi-lizwi semizi-mveliso ngaphambi kokuba zingasebenzi

Eyona ndlela ikhawulezayo yokusombulula ingxaki yenkqubo yesandisi-lizwi kukufumanisa ukuba ingxaki ikwi-electric, i-acoustic, okanye ikwi-environmental.

Ukuba isithethi asithethi, jonga itshaneli ye-amplifier, ukuqhubeka komgca, kunye ne-zone fuse kuqala. Ukuba isiphumo sibuthathaka kodwa sikhona, jonga ii-transformer taps, ukumelana nekhebula, kunye nomonakalo onokwenzeka wamanzi. Ukuba isandi sigqwethekile, ingxaki isenokuba yi-driver eyonakeleyo, i-amplifier clipping, okanye i-grille ekhululekileyo ebangela isandi.

Indlela elula yentsimi kukuthelekisa isithethi esinye esirhanelwayo sefektri kunye neyunithi eyaziwayo kwindawo enye. Ukuba ingxaki ilandela isithethi, ingxaki ikwindawo leyo. Ukuba ingxaki ihlala kwindawo leyo, intambo okanye i-amplifier kusenokwenzeka ukuba yimbangela eyintloko. Loo thelekiso inye inokonga iiyure kwinethiwekhi yesandisi-lizwi semizi-mveliso emininzi.

Amaqela okulungisa kufuneka ajonge ukuba akukho kuqhuba ngokugqithisileyo na. Kwiinkqubo zemigca ye-100 V, useto olungalunganga lwetap lunokugqithisa i-amplifier kwaye ludale ukuphazamiseka ixesha elide ngaphambi kokuba kwenzeke ukungasebenzi kakuhle. Uphawu lusenokubonakala ngathi sisithethi esibi, kodwa ingxaki yokwenyani idla ngokuba kukushukuma koyilo lwenkqubo emva kokwandiswa okanye ukulungiswa kwendawo.

Xa ukusilela kuphinda kwenzeke kwindawo enye, khangela izizathu zokusingqongileyo. Isithethi se-loading dock esivezwe kwi-spray, i-forklift vibration, kunye nokutshintsha kobushushu kuya kusilela ngokwahlukileyo kwiyunithi ye-corridor yangaphakathi ecocekileyo. Ukulungiswa okuchanekileyo kusenokuba yindawo engcono yokuvala, i-bracket eyahlukileyo yokufakela, okanye ukufuduselwa kwenye indawo endaweni yokutshintshwa okuphindaphindiweyo.

Ukukhetha amaxesha okugcina inethiwekhi yesithethi yefektri

Amaxesha okugcina izinto kufuneka abonise ubunzima bemeko-bume, kungekhona nje ukulula kwekhalenda.

Isityalo esicocekileyo sangaphakathi sinokusebenza rhoqo emva kokuhlolwa kokusebenza kwekota, ngelixa indawo yangaphandle okanye yokuhlamba ingadinga ukuhlolwa nyanga zonke. Iindawo ezinobungozi okanye ezingxamisekileyo kufuneka zihlolwe rhoqo kuba iindleko zokungasebenzi ziphezulu. Ukuba inkqubo yesandisi-lizwi ixhasa ii-alamu, ukuphuma, okanye izibhengezo ezibalulekileyo zeshifti, yiphathe njengezixhobo zokhuseleko lobomi kunezixhobo ze-AV eziqhelekileyo.

Kwimodeli yocwangciso olusebenzayo, iindawo ezininzi zoshishino zisebenzisa ishedyuli enamanqanaba amathathu:

• Ukuhlolwa kwenyanga nganye kweendawo ezivezwe, ezimanzi, ezinothuli, okanye ezingcangcazela kakhulu.
• Ukuhlolwa kwekota nganye kwemigangatho yemveliso eqhelekileyo kunye neendawo zangaphandle ezigqunyiweyo.
• Inkonzo yonyaka enzulu yokuphononongwa ngokupheleleyo kwe-acoustic, ukutshintshwa kwetywina, kunye nokuhlolwa kwamaxwebhu.

Le ndlela ikwaxhasa uhlahlo-lwabiwo mali. Endaweni yokutshintsha zonke izipikha zesandisi-lizwi zemizi-mveliso xa kuqala ukuguguleka, utshintsha kuphela iiyunithi ezibonisa ukuwohloka okunokulinganiswa. Ekuhambeni kwexesha, oko kunciphisa uxinzelelo lwesitokhwe esisele kwaye kuthintele ukungasebenzi okungalindelekanga.

Kumaqela okuthenga ubunjineli, isithethi esilungileyo nesinobuhlobo nokugcinwa asisiso esibiza kakhulu. Seso sinokufikelela okucacileyo kokufakelwa, iindawo ezinokutshintshwa, inkxaso yokubonelela ezinzileyo, kunye nodidi lokhuseleko olubhaliweyo. Yiyo loo nto amaqela amaninzi eprojekthi ethelekisa kungekuphela nje isandi esiphumayo kodwa kunye nenkonzo, ukufumaneka okushiyekileyo, kunye noyilo lofakelo ngaphambi kokuba kugqitywe inkqubo yesandisi-lizwi.

Anjani amaxwebhu amahle okugcinwa kwesandisi-lizwi semizi-mveliso?

Amaxwebhu alungileyo aguqula ukugcinwa kube yinkqubo ephindaphindwayo.

Isandisi-lizwi ngasinye semizi-mveliso kufuneka sibe nerekhodi equka indawo, imodeli, itephu yombane, umhla wokufakwa, udidi lokhuseleko, iziphumo zovavanyo lokugqibela, kunye nembali yokutshintshwa. Ukuba indawo inezakhiwo ezininzi okanye iindawo zemveliso, yongeza isalathiso semephu okanye i-ID yempahla. Oku kwenza ukulandelelwa kweempazamo kukhawuleze kakhulu xa kuvela ingxaki yekhasi ngexesha lokutshintsha ishifti okanye ukuqhuba okungxamisekileyo.

Iingxelo zolondolozo nazo kufuneka zibambe indlela yovavanyo. Inqaku elithi "ivavanyiwe Kulungile" aliluncedo kangako kunelo lirekhoda iziphumo ezilinganisiweyo, ukugqwethwa okubonweyo, kunye nomgwebo wokuqondwa ngokwendawo. Okukhona idatha ihambelana ngakumbi, kokukhona kulula ukubona iindlela zokuwohloka ngaphambi kokuba ukusilela kubonakale.

Kwiisayithi ezineenkqubo zonxibelelwano ezixutyiweyo, uqeqesho olufanayo loxwebhu lungasetyenziswa kwiintsapho zezixhobo. Umzekelo, isityalo sinokusasazaiinkqubo ze-intercom, iiyunithi zongxamiseko, kunye neenethiwekhi zezithethi zasefektri kunye, ngoko ke irejista yeeasethi kufuneka ibonise indlela inxalenye nganye enegalelo ngayo kumjelo wonxibelelwano ofanayo.

Ngokwesikhokelo se-NIST malunga nemigaqo yokulandelela umlinganiselo, izigqibo zokugcinwa eziphindaphindwayo zixhomekeke kumlinganiselo ohambelanayo kunye neenkqubo ezibhaliweyo. Loo mgaqo usebenza ngokuthe ngqo kuvavanyo lwesandisi-lizwi: ukuba awulinganisi ngendlela efanayo ngalo lonke ixesha, awunakukwazi ukungqina ngokuthembekileyo ukuphucuka okanye ukonakala.

Iindlela ezilungileyo zokwandisa ubomi besandisi-lizwi semizi-mveliso

Iinkqubo ezihlala ixesha elide zezo zikhuselekileyo kuxinzelelo olunokuthi luphetshwe.

Sebenzisa umlinganiselo ochanekileyo wokuvalwa kwendawo, kuphephe ukutyibilika kweentambo ezincinci, kwaye uqinisekise ukuba isithethi sifakwe ukuze amanzi angangeni kwi-grille okanye kwi-bracket. Gcina ukufikelela okucacileyo kwenkonzo ejikeleze iyunithi ukuze iingcali ziyihlole ngaphandle kokonakalisa indlu. Ukuba indawo isebenzisa ukuhlamba rhoqo, qinisekisa ukuba iikhemikhali zokucoca ziyahambelana nezinto zokuvalwa kunye noyilo lwe-gasket.

Ukhetho olubini loyilo lwenza kube lula ukugcinwa kwezixhobo ngokuhamba kwexesha. Okokuqala, sebenzisa izixhobo zokufakela ezisemgangathweni apho kunokwenzeka khona ukuze ukutshintshwa kube ngokukhawuleza.
