Kev txhim kho tsev tsis muaj zog ntawm cov xov hlau hluav taws xob

Lub tsev nyob hauv lub zej zog niaj hnub no yuav tsum tsis tsuas yog yooj yim thiab xis nyob, tab sis kuj tseem ntse, lom zem, thiab nyab xeeb. Qhov no yuav tsum muaj qhov hluav taws xob tsis muaj zog hauv tsev tam sim no. Cov hlua xaim hluav taws xob tam sim no yog "txoj hlab" hauv chav tsev, lawv xa cov hluav taws xob txuas mus rau ntau lub twj, kom ua tiav raws li daim ntawv thov saum toj no.


1. LAN kaw lus

Ua raws li cov ntsiab lus tseem ceeb: Cov chaw hauv cheeb tsam peb xav tsim yog lub hnub qub topology. Cov node lossis kev sib txuas cmuaj peev xwm tsis ua haujlwm tsuas yog cuam tshuam rau ib qho. Nruab qhov RJ45 qhov chaw faib khoom vaj huam sib luag uas tau ua lub luag haujlwm ntawm kev tswj kom zoo nyob rau hauv lub thawv ntawv nkag.Txhua Ethernet Hlab hlau los ntawm lub qhov (socket) txuas nrog sab nraum qab ntawm lub vaj huam sib luag faib tawm, thiab cov ntaub ntawv nkag mus rau lub thawv yuav tsum tau nruab nrog lub network qhib me me, uas txuas nrog rau sab pem hauv ntej interface ntawm lub vaj huam sib luag faib tawm Ethernet Hlab hlauCov. Txhawm rau khaws cov ntaub ntawv hauv lub vev xaib rau Is Taws Nem thiab ntau qhov ntawm cov xov xwm network uas yuav muaj nyob yav tom ntej. Peb xav tau tsawg kawg ob qhov cuam tshuam network uas txhua chav xav tau. Ib qho tuaj yeem siv rau lub network thiab lwm tus tuaj yeem siv los siv xov tooj. Qhov no yog nyob ntawm lub network thiab xov tooj multiplexing. Thiab qhov tseev kom muaj ntawm kev sib txuas rov qab kab. Xws li RJ45 cov vaj huam sib luag faib tawm, cov xov paj sib ntswg, RJ45 cov xov xwm qauv, Kuv yuav tsum xaiv cov npe nrov super tam sim no, uas tuaj yeem ua tau raws li qhov xav tau ntawm tam sim no thiab yav tom ntej.

Wiring key points: better materials should be selected for the household cmuaj peev xwm television kaw lus, and special two-way, high-shielding, high-isolation 1000MHZ CoaxialCmuaj peev xwm and panel, distributor, and amplifier (required when more than 4 branches are required) should be used. The distributor should use high-quality devices marked with 5-1000MHz technical indicators. The cmuaj peev xwm should be a 75-5 type, four-shielded physical foamed coaxialcmuaj peev xwm with good shielding performance against external interference signals to ensure the signal level of each room; the cmuaj peev xwm TV image is clear and there is no net interference. The wiring of the CATV yog qhov yooj yim. Rau cov tsev lag luam zoo tib yam, peb tsuas yog yuav tsum nruab qhov xa ib-rau-plaub tus neeg muab khoom hluav taws xob hauv tsev neeg cov ntaub ntawv kab ntawv txhawm rau faib covCmuaj peev xwm TV connected to the outside to the living room and each room.
