Qaphela: Nceda usebenzise unikezelo lwamandla olongezelelweyo lwe-12V kwinethiwekhi ye-RS485 enikezelweyo, oku kuya kuphucula kakhulu ukuthembeka konxibelelwano, ukomelela.
I-topology yenethiwekhi esetyenziswa ngokuqhelekileyo ukupheliswa kwesakhiwo sebhasi, ayixhasi inethiwekhi engqukuva okanye emile okwenkwenkwezi. Yonke i-node i-serial exhunywe ngebhasi enye yinto efanelekileyo, kumfanekiso ongentla, i-topology yenethiwekhi ngokubanzi ye-A8-05B inkqubo ibonisiwe. Ii-N nodes ziqhagamshelwe kwinethiwekhi yeengongoma ezininzi. Kwizantya eziphezulu kunye nemigca emide, ukuchasana kokuphelisa kuyimfuneko kuzo zombini iziphelo zomgca ukuphelisa ukubonakaliswa. Sebenzisa i-100 Ω izixhasi kwiziphelo zombini (ifuna kuphela ukuba ubude bocingo > 2km). Uthungelwano kufuneka luyilwe njengomgca omnye onamathontsi amaninzi, hayi njengenkwenkwezi. Nangona ubude bekhebula bubonke bunokuba bufutshane kuqwalaselo lwenkwenkwezi, ukupheliswa okwaneleyo akusenakwenzeka kwaye umgangatho womqondiso unokuthotywa kakhulu. Kumzobo woku-1 obonisa ngokulandelayo, b, d, f ludibaniso oluchanekileyo kwaye a, c, e lunxibelelwano olungalunganga.
Umzobo woku-1
Xa usebenzisa i-shield network wire (STP), Kufuneka ugcine ukuqhubeka komgangatho okhuselayo ogudileyo, kwaye udibanise uMhlaba kwindawo enye, njengoko kubonisiwe kwidayagram.
Kufuneka ucingo
Inkqubo esetyenzisiweyo ye-CAT-5E UTP kunye nentambo ye-STP.
Indlela yokukhetha intambo ye-CAT-5E efanelekileyo?
Ukumelana nocingo ngalunye kufuneka ≤35Ω xa ubude bumalunga ne-305M (ubude be-FCL).
Isikhululo somnyango ukuya kwiSibonelelo soMbane sisetyenziswe iRVV4*0.5, ukutshixa iRVV2*0.5 esetyenzisiweyo.
Isilumkiso:
Umfanekiso wesitishi somnyango awuyi kuboniswa ngokupheleleyo kwiscreen seVisual Room-station xa Igumbi-isikhululo sahluke kakhulu kumbane wevidiyo, kwiindawo ezifanelekileyo kwibhasi yokwakha ukwandisa umbane unokusombulula le ngxaki. Ubonelelo lwamandla lwevidiyo ngokubanzi oluvela kwindawo ebonwayo Isikhululo segumbi sowona mgama mkhulu awunakudlula iimitha ezingama-30.
Umzobo wesi-2
Scotchlok
UTP&UTP
UTP&Isixhobo's off-line
Ngaphandle kwe-intanethi&Off-line
Kufuneka kuphela i-vice emhlathini
Umfanekiso wesiphumo
Ngenxa yokuba umgangatho we-RJ-45 wenzelwe ukusetyenziswa ngaphakathi emnyango kuphela, awunabungqina bokufuma kwaye kulula kakhulu ukungcoliswa okanye ukufakwa kwi-oxidized. Ukuba iNtloko ye-RJ-45 iphukile, kukho iingcali ezibambe izixhobo zobugcisa ezifunekayo ukulungisa iphutha, oku kuya kubangela iindleko eziphezulu zokugcina.
IScotchlok yile nto kanye siyifunayo. Ngaphezulu kweminyaka engama-45 eyadlulayo, i-3M yazisa isiqhagamshelo sokuqala se-insulation displacement-i-Scotchlok Connector UR. Namhlanje, ngokunyuka kwemfuno ye-high-speed kunye ne-high-bandwidth networks, uchungechunge olupheleleyo lwe-3M izixhumanisi kunye nezixhobo ziye zavela kwakhona. Nceda undwendwele www.3M.com ngolwazi oluthe kratya lweScotchlok.
System Overview
Iimpawu zesisombululo
I-Visual Intercom Function
Umsebenzisi unokufowunela ngokuthe ngqo imonitha yangaphakathi kwifowuni yomnyango ukuqonda i-intercom ebonakalayo kunye nomsebenzi wokuvula. Umsebenzisi unokusebenzisa imonitha yangaphakathi ukufowunela ezinye iimonitha zangaphakathi ukuze ziqonde umsebenzi we-intercom wendlu ukuya kwindlu.
Umsebenzi woLawulo lokuFikelela
Umsebenzisi unokufowunela imonitha yangaphakathi ukusuka kwisikhululo sangaphandle emnyango ukuze uvule umnyango nge-intercom ebonakalayo, okanye usebenzise ikhadi le-IC kunye negama lokugqitha ukuvula umnyango. Umsebenzisi unokubhalisa okanye akhansele ikhadi le-IC kwaye usete igama lokugqitha kwisikhululo sangaphandle.
Umsebenzi weAlam yoKhuseleko
Umsebenzisi unokusebenzisa imonitha yangaphakathi ukujonga ividiyo yesikhululo sangaphandle emnyango, kwaye ujonge ividiyo yekhamera ye-analog efakwe ekhaya.
