Chizindikiro cha elevator cha pansi 20, seti ya "elevator"chobwereza chizindikiro"Kuthetsa vuto la kufalikira kwathunthu. Imathandizanso magulu a NR41 ndi NR42 a 5G. Mtundu uwu wachokulitsa chizindikiroyopangidwa mwapadera kuti ipereke chivundikiro cha elevator, kuti makasitomala aziyamikiridwa kwambiri.
Kusanthula kwa Pulojekiti
Tsopano pansi pa anthu ammudzimo zikukwera kwambiri, ndipo elevator yakhala njira yofunika kwambiri yoyendera. Komabe, elevatorkuphimba chizindikiroSikokwanira, chizindikirocho ndi chofooka, ndipo ngakhale chizindikirocho chimatayika, zomwe zabisa zoopsa zachitetezo kwa anthu omwe amakwera chikepe. Chifukwa chake, ogwira ntchito yoyang'anira ayenera kukonza ndikuwonjezera kufalikira kwa chizindikiro cha chikepe kuti atsimikizire chitetezo cha okhalamo.
Ntchitoyi ili m'nyumba yatsopano ku Hunan, yokhala ndi ma elevator awiri okhala ndi zipinda 20 komanso chipinda chapansi. Chifukwa cha ndemanga ya mwiniwake mobwerezabwereza kuti elevator ilibe chizindikiro, ogwira ntchito oyang'anira adapeza gulu la Lin Chuang kuti lichite.kuphimba chizindikiro.
Ndondomeko ya kapangidwe
Timaganizira kuti pansi pa elevator pali zipinda 20, ndipo kugwiritsa ntchito "elevator signal repeater" ndikotsika mtengo komanso kothandiza.
Chikepecho chimagawidwa m'magulu awiri a zida, chipangizo chachikulu chowongolera ndi chipangizo cha galimoto, mwachidule: chipangizo chachikulu chowongolera "chimatsogolera" chizindikiro kuchokera kunja kupita ku shaft ya elevator, ndipo chipangizo cha galimoto chimasamutsa chizindikiro cha shaft ya elevator, ndikuphimba chikepe chonse.
Ndondomeko yogwirizanitsa zinthu
ChikepeChobwerezabwereza ZizindikiroImathandizira 2G-5G, kuwonjezera ma signal a frequency atatu, oyenera kuphimba ma signal a elevator osakwana 30 floors, frequency band yowonjezera imaphatikizapo NR41 ndi NR42, liwiro la netiweki ya "5G" ndi lachangu kwambiri! Yopangidwira kuphimba ma signal a elevator, ikangoyambitsidwa, imayamikiridwa kwambiri.
Njira Yokhazikitsira
1. Pezani malo panja pomwe gwero la chizindikiro (ma gridi opitilira atatu) lili bwino (monga chipinda chapamwamba), ndikuyika antenna yolandirira ya chipangizo chachikulu chowongolera apa. Antena yolandirira iyenera kuyang'ana nsanja ya chizindikiro.
2.Gwiritsani ntchito chodyetsera kuti mulumikize antenna yolandirira yakunja ku RF_IN kumapeto kwa amplifier, ndi RF_OUT kumapeto kwa amplifier ku antenna yotumizira yamkati. Onetsetsani kuti kulumikizana kuli kokhazikika.
3. Onetsetsani kuti zipangizo zonse zalumikizidwa ndipo zolumikizira zakhazikika, ndipo yatsani amplifier. Kenako ikani galimotoyo mofanana, ndipo chizindikiro cha elevator chidzadzaza nthawi yomweyo!
Antena yolandirira imayikidwa pamwamba pa elevator.
Antena yotumizira imayikidwa mkati mwa elevator.
Ziwirizi zimalumikizidwa ku makina akuluakulu pogwiritsa ntchito chodyetsera.
4. Kuzindikira Chizindikiro Pambuyo poyika, pulogalamu ya "CellularZ" imagwiritsidwanso ntchito kuzindikira chizindikiro cha elevator, ndipo mtengo wa RSRP umawonjezeka kuchokera ku -116dBm kufika pa -78dBm, mphamvu yowonjezera imakhala yamphamvu kwambiri!
RSRP ndiye mtengo wamba woyezera ngati chizindikirocho chili chosalala, nthawi zambiri, chimakhala chosalala kwambiri pamwamba pa -80dBm, ndipo palibe netiweki yomwe ili pansi pa -110dBm.
Pambuyo poyika chuma cha elevator, sichimangolankhula bwino mu elevator, komanso chimatha kusokoneza masewera afupiafupi a pakompyuta, ndipo ogwira ntchito yoyang'anira anthu ammudzi amayamikira kuphimba kwake! Ngati anthu ammudzi mwanu ali ndi vuto la chizindikiro, mutha kusiya zambiri zanu zolumikizirana kumbuyo.
