Wireless Tsev Router Nrog Kev Siv Qhov Kev Ntsuas Zoo: 5 Cov Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30

Kuv loj hlob nyob rau hauv thiab ib puag ncig cov nkoj ua cov xov hluav taws xob thiab tswj cov vaj huam sib luag, thiab muaj cov khoom ntsuas thiab ntsuas uas ib txwm pom muaj txuas nrog cov cav me me diesel xyaw.

Hnub no kuv ua haujlwm raws li tus tsim qauv tsim kev cuam tshuam rau cov khoom siv sib tham. Raws li qhov no, Kuv nyiam rov siv cov ntsuas sib piv qub los tso saib cov ntaub ntawv network hauv tib neeg cov ntawv nyeem tau zoo dua. Tuav kuv yav dhau los rau tam sim no rau qee qib. Kuv siv 3 rev counter, tsim qauv huv, uas tuaj ntawm ib lub nkoj uas kuv txiv muaj thaum kuv tseem yog menyuam yaus thiab txuas nws mus rau lub wireless router kuv tau pw ib ncig ntawm kev ua haujlwm. kev siv tsheb khiav ntawm kuv lub tsev network thiab internet.

Kauj ruam 1: Txheej txheem cej luam ntawm Nws Ua Haujlwm Li Cas

Muaj ntau txoj hauv kev los nrhiav seb ntau npaum li cas bandwidth raug siv. Qhov no yog thawj kis ntawm cov digital rau kev sib piv ntawm kev siv, Kuv tau xaiv kom yooj yim siv uplink LED raws li qhov qhia txog qhov ntau ntawm cov tsheb hla ntawm kuv lub tsev thiab internet. Qhov no muaj qee qhov kev txwv loj. Kuv tsis paub tias kho vajtse (broadcom chipset) lossis firmware (dd-wrt) muaj cov piv txwv algorythm uas tsav lub LED, tej zaum yog chipset. Nov yog thawj qhov teeb meem, LED yuav tsum nyob ib puag ncig 30mS rau tib neeg lub qhov muag kom sau npe kom raug. Networking pob ntawv luv dua qhov no. Yog li tus router yuav tsum ua lej me ntsis thiab txhais cov kev sib txuas hauv network tiag kom qeeb LED ntsais muag. Yog li muaj qhov piv txwv poob, LED yog qhov kwv yees kwv yees ntawm cov tsheb khiav mus los, tom qab ntawd, Kuv yuav tsum txhawb 3.3V uas tsav lub LED mus txog 14V xav tau rau lub rooj rov qab (feem ntau cov tsheb hu thiab ntsuas zoo li no yog kab 0- 12 lossis 14V) Rau qhov no kuv siv qhov yooj yim op-amp Circuit. Tsis muaj qee qhov swanky Digital rau Analogue hloov pauv kuv rov xoob ntau qhov kev daws teeb meem Hauv qhov kawg, qhov no tsis yog qhov sawv cev zoo heev ntawm kev siv bandwidth siv, tab sis qhov txuas ntxiv kuv tau txais hauv qhov project, ntau nws los ua qhov khoom nthuav Nco tseg: Kuv tau ua haujlwm nrog cov hais mav los ntawm https://dd-wrt.com/dd-wrtv2/index.php nplua nuj qhib qhov firmware.

Kauj Ruam 2: Pem Hauv Ntej Vaj Huam Sib Luag

Kuv desoldered cov LEDs los ntawm tus router pcb thiab xa lawv tawm mus rau pem hauv ntej nrog kab xov txuas thiab lub taub hau txuas. Chiseled tawm ib cov channel rau overlay yog li nws muaj qhov ntxig zoo nkauj. Kuv poob rau hauv kev hlub nrog lub zog hloov pauv los ntawm ib qho ntawm kev tsim kho vajtse ntawm kev ua haujlwm, hmoov tsis nws yog qhov hloov pauv ib ntus yog li kuv siv sijhawm ntau lub sijhawm rov qab haum N /O microswitch nrog lub xiav LED glued rau lub taub. Qhov ntug ntawm ntu vaj huam sib luag pem hauv ntej tau hloov pauv.

Kauj Ruam 3: Op-amp Circuit

Muaj ob theem ntawm LED ntawm lub rooj tsavxwm tseem ceeb thiab lub rooj sib tham hloov kho. 1) Rho cais cov op-amp Circuit Court los ntawm lub rooj tsav xwm router. Qhov no ua tiav nrog 'tsis' nyob rau hauv daim ntawv ntawm 74HC04. Ib tus invertor uas muaj rooj vag uas yuav tsis kos ib qho tam sim no los ntawm lub router thiab yuav tso tawm lub teeb liab raws li qhov rov qab ntawm nws cov tswv yim. Tus txiv neej no los nrog 6 lub rooj vag, yog li yog tias koj xav tau txais tib lub teeb liab tso tawm raws li lub teeb liab nkag koj khi rau lub rooj vag rov qab. Missing Link) Kuv tau muaj theem nrab uas tau tsim los ua kom plaub fab xwm yeem yoj teeb liab tsav tsheb LED mus rau qhov sib piv zoo sib xws nce/poob tus nqi rau lub khoos phis tawm tshiab, txawm li cas los xij cov tshuab khoos phis tawj tau muab qhov tsim nyog. Yog li, hauv qee qhov kab duab koj yuav pom thiab RC Low pass filter.2) Op-amp. Kuv xaiv cov nti qub heev, LM 741, uas ua haujlwm tab sis tuaj nrog ntau qhov kev txwv uas cuam tshuam loj heev rau kev tsim. Nco tseg yuav ua li cas lub rooj sib tham tsis rov mus rau xoom, thiab thaj tsam zoo li hover ncig ib puag ncig ntawm lub xov tooj. Cov kev txwv ntawm op-amp. Leason tau kawm thiab dhau lub asthiv tom ntej no kuv yuav txhim kho qhov kev sib tw no kom muaj kev nthuav dav dav.

Kauj Ruam 4: Qhov & Cov Cuab Yeej

Qhov List ListRev txee: Qhov no yog ib feem kuv 'rov siv', VDO meter, tseem muaj qee lub nkoj nuv ntses ntsaws rau ntawm nws. Kev ntsuas pom nws cov yam ntxwv yog tias nws nyiam pub cov kab tawm ntawm 0-12VRouter: Qhov tsawg tshaj plaws PCB daim ntawv foos hauv khw uas kuv pom yog BuffaloSoftware: Kuv tau teeb tsa https://www.dd-wrt.com/dd -wrtv2/index.php Qhov no tsis yog qhov tsim nyog tab sis kuv tsis tuaj yeem txhawb nqa cov software no txaus. Ntoo: Ntoo qhib ntoo los ntawm cov khoom siv kho vajtse hauv ib cheeb tsam (lossis tsev xa khoom hauv tsev) Lub khob cij rau kev sim thiab Protoboard rau zaum kawg op-amp CircuitOp-amp: 741, yuav siv ib feem zoo dua rau daim ntawv thov no hauv kev hloov kho tom ntej ntawm D rau A CircuitBuffer: 74hc04 hex invertorDecal: cov nyiaj siv ua haujlwm ua ntej daim ntawv, haum rau koj lub tshuab luam ntawv (laser/inkjet) Cov cuab yeej Hluav taws xob: Siv tooj dag hlau, Multimeter thiab tau yog tias koj muaj ib qho txhaum Kev ntsuas ntoo: cov saw pom, lub rooj pom, cov txua ntoo txua ntoo, cov cuab yeej ua kom tuag, kua nplaum & dowelsDecal: txhua daim duab thov. thiab feem ntau ntawm koj tus lej tseem txuas nrog

Kauj ruam 5: Rooj plaub

Nov yog ib txoj hauv kev ua liaj ua teb heev los ua ib rooj plaub, txoj hauv kev yog yuav siv qee qhov pheej yig chipboard lossis ntoo thuv thiab veneer nws nrog ntoo zoo dua. Hauv kev txaus siab ntawm kev tsis muaj peev xwm Kuv txheej caked rooj plaub los ntawm ib feem ntawm ib leeg txiav daim phiaj.

Milled tawm cov cheeb tsam xav tau rau lub rooj rov kho dua, router pcb board, op-amp protoboard thiab channel rau aerial coax mus rau tom qab. Kuv cim txhua ntu los ntawm tus qauv, txiav nrog cov ntawv pom, lo thiab lo rau hauv av. Ua tiav nrog cov xim tsaus nti thiab ib nrab ci.
