Posachedwapa ndidazindikira kuti mphaka wowonda komanso wamantha kwambiri, wokhala ndi maso achisoni kwamuyaya, adakhala m'chipinda chapamwamba ...
Sanalumikizane, koma adatiyang'ana patali. Ndinaganiza zomupatsa chakudya chamtengo wapatali, chomwe nkhope zathu zamphaka zapakhomo zimagwedezeka. Ngakhale pambuyo pa miyezi iwiri ya chithandizo, mphaka adapewabe zoyesayesa zonse kuti alankhule naye. Nβkutheka kuti anachilandira kwa anthu mβmbuyomo, zomwe zinapangitsa kuti akhale wamantha.
Monga akunena, popeza Muhamadi sapita kuphiri, phirilo lidzafika kwa Muhamadi. Pokhudzana ndi kusintha kwa nyengo ndi nyengo yozizira yosapeΕ΅eka, ndinaganiza zomanga "nyumba" yamtundu wina, ndikuyiyika pagawo lake, ndiko kuti, m'chipinda chapamwamba.
Maziko a nyumbayi ndi bedi lopangidwa kuchokera ku bokosi lawiri kuchokera ku mango a Hainan. Pawiri ndi pamene bokosi limalowetsedwa mu chivindikiro cholowetsedwa kuchokera mubokosi lomwelo. Theka lirilonse liri pawiri, kotero bokosilo limakhala la quadruple komanso la mphamvu zowonjezereka. Anthu aku China amadziwa zambiri za mabokosi, chifukwa kukula kwake kunali kwabwino kwa amphaka. π Pakati pa zigawozo, ndinayika laminate m'bokosi kuti muwonjezere kutentha. Kenako, ndimayika zigawo ziwiri za mphira wa thovu la centimita pansi, ndipo pamwamba - thaulo lakale la terry lopindidwa patatu.
Podziwa kuti "sitepe yamkaka" ndi chiyani ndikutulutsa zikhadabo, komanso momwe zofunda zilizonse zimadumphira pakapita nthawi, ndinasoka zigawo zonse zitatu za thaulo mpaka m'bokosi. Komanso, sanasoke ndi ulusi, womwe umatha kutafunidwa mosavuta kapena kung'ambika ndi zikhadabo, koma ndi waya wamkuwa (wokhotakhota) mu insulation ya vanishi, wokhuthala mpaka 1,2 mm. Inde, ndizovuta, koma ndi zotsutsana ndi zowonongeka, kuchokera ku zikhadabo za amphaka kapena mano.
Pogwiritsa ntchito njira yofananira, ndinasoka ngodya zonse kuti zofundazo zikhalebe ndi mawonekedwe ake, ngakhale atachitiridwa nkhanza ndi wokhalamo.
Koma sikokwanira kungoyika bedi lofewa, chifukwa m'nyengo yozizira mumakhala chisanu mu chipinda chapamwamba, ndi kutentha komweko kunja. Izi zikutanthauza kuti ntchitoyo idawuka kuti apange chinthu chonga "dome" mozungulira pabedi kuti asunge kutentha kochokera kwa mphaka. Kuti achite izi, bedi lokonzekera linayikidwa mkati mwa bokosi lalikulu.
Pakhoma la mbali ya bokosi lakunja ndinadula mtundu wa "khomo", ndikudzitsekera ndekha ndimeyi kuti kutentha kusathawe kwambiri.
Pamene ntchitoyo inkapitirira, nkhope za amphaka zapakhomo zinatha kuyesa nyumba yofewa mofewa kangapo:
Anasangalala kwambiri akupondaponda mozungulira pabedi, zomwe mkati mwa mphindi 5 nthawi yomweyo zidapangitsa aliyense kugona:
Chabwino, popeza titha kusunga kutentha mozungulira wokhalamo pogwiritsa ntchito chozungulira chotsekedwa kunja, ndiye bwanji osapanga kutentha komweko, kuti mphaka wokhalamo apulumutse kutaya kutentha m'thupi lake. Kuti tichite izi, zigawo ziwiri za makatoni wandiweyani okhala ndi kusungunula kwamafuta zidayikidwa pansi pabokosi lalikulu, pomwe zinthu ziwiri zogwira ntchito, zotentha zotentha zopangidwa ndi chingwe cha multi-core constantan zidayikidwa. Amapangidwa kuti azipereka mphamvu kuchokera ku USB, ndiye kuti, 5 volts. Nditawalumikiza motsatizana, ndidawatembenuza kukhala mphamvu kuchokera ku 9 - 10 volts, ndikugwiritsa ntchito pano pafupifupi 1 Ampere, zomwe zingatipatse mphamvu yotenthetsera ya 9-10 Watts. Ndipo izi ndizochuluka kale kwa voliyumu yaying'ono yotentha.
Popeza nyamayo ndi yosadziwa kuwerenga, imatha kutafuna chingwe chamagetsi pamagetsi otenthetsera m'bokosi. Ndipo ngati ndi choncho, ndiye kuti muyenera kuganizira za nkhani yotsimikizira chitetezo chotsimikizirika cha thanzi la nyama, kuchokera kugwedezeka kwa magetsi. Kuti ndikwaniritse ntchitoyi, ndinasiya kugwiritsa ntchito zida zamakono zamakono ndikusankha mtundu wakale wa magetsi a thiransifoma, ndi kudzipatula kwa galvanic kuchokera pa intaneti (sanaphatikizidwe muzithunzi). Ngakhale ma generator a pulse amakhalanso ndi decoupling, amakhalabe "pinch" pang'ono, mwachitsanzo pokhudzana ndi dera lotenthetsera.
Chabwino, popeza tinalowa m'nyumba ndi "mabelu ndi mluzu", ndinaganiza kuti ndiyika bokosilo m'chipinda chapamwamba, ndikukhomerera gable ndi sheathing ndi kutsazikana. Nanga bwanji ngati tichita mtundu wina wowunikira makanema? Zidzakhala zosangalatsa kudziwa ngati mphaka adzalandira mwayi pa lingaliro lonse? Sindinkafuna kugwiritsa ntchito chingwe cha kanema; zimafuna zowonera zambiri, motero ndidaganiza zoyamba kutumiza kanema pawayilesi. Nthawi ina ndidakumana ndi chosinthira makanema chotenthedwa cha 5,8 GHz, chomwe mwini wake adakwanitsa kuwotcha. Makamaka, gawo lotulutsa mphamvu ya RF amplifier lidawotchedwa. Nditachotsa gawo lolakwika la microcircuit, komanso "mapipi" onse a SMD ozungulira, ndidalumikiza siteji yoyendetsa mavidiyo ndi coaxial "bypass" ku cholumikizira cha SMA cha mlongoti. Pogwiritsa ntchito makina owonetsera vekitala a Arinst 23-6200 MHz, ndinayeza choyezera cha S11 ndikuwonetsetsa kuti kulepheretsa kutulutsa kwa ma frequency ogwiritsira ntchito kumakhalabe m'malire ovomerezeka, pafupifupi 50 Ohms.
Chidwi chinalowa mkati, ndiye mphamvu yeniyeni ya vidiyo "yothena" yotereyi ndi yotani, ngati mumadyetsa mlongoti mwachindunji kuchokera ku "boost", ndiko kuti, popanda chokulitsa mphamvu konse? Ndidayezera pogwiritsa ntchito mita yamphamvu ya microwave yolondola kwambiri ya Anritsu MA24106A, munjira yoyenera mpaka 6 GHz. Mphamvu yeniyeni pa njira yotsika kwambiri ya transmitter iyi, 5740 MHz, inali ma milliwatts 18 okha (mwa 600 mW). Ndiko kuti, 3% yokha ya mphamvu yapitayi, yomwe ili yochepa kwambiri, koma yovomerezeka.
Popeza zimachitika kuti mphamvu ya microwave yomwe ilipo sikokwanira, ndiye kuti kufalitsa kwabwinoko kwa mtsinjewu muyenera kugwiritsa ntchito mlongoti wabwinoko.
Ndinapeza mlongoti wakale wa gulu ili la 5,8 GHz. Ndinakumana ndi mlongoti wamtundu wa "helical wheel" kapena "clover", ndiye kuti, mlongoti wokhala ndi ventor yozungulira mozungulira, makamaka kumanzere kozungulira. M'madera akumidzi, ndi bwino kuti chizindikiro sichidzatulutsidwa ndi polarization, koma mozungulira. Izi zithandizira ndikuwongolera chithunzi cholimbana ndi kusokoneza kosalephereka pakulandila komwe kumachitika chifukwa cha zopinga ndi nyumba zapafupi. Chithunzi choyamba, chomwe chili pakona yakumanja yakumanja, chikuwonetsa momwe kufalikira kozungulira kwa vector yofalitsa mafunde amagetsi amagetsi amawonekera.
Pogwiritsa ntchito chowunikira chatsopano cha vector network (chipangizo cha VNA), nditatha kuyeza VSWR ndi kutsekeka kwa mlongoti uwu, ndidakhumudwa, chifukwa zidakhala zocheperako. Potsegula zivundikiro za mlongoti ndikugwira ntchito ndi makonzedwe a malo a ma vibrator onse 4 kumeneko, ndi chikhalidwe chofunikira kwambiri choganizira za permeability wa zovundikira pulasitiki, tinatha kuchotsa kwathunthu parasitic reactivity onse capacitive ndi inductive chikhalidwe. Panthawi imodzimodziyo, kunali kotheka kuyendetsa kukana kwapakati pa chithunzi chozungulira cha Wolpert-Smith (ndendende 50 Ohms), pamafupipafupi osankhidwa a njira yotsika ya transmitter yomwe ilipo, yomwe ikukonzekera maulendo afupipafupi. 5740 MHz:
Mogwirizana ndi izi, mulingo wa zotayika zowonekera (pa avareji ya kukula kwa logarithmic magnitude graph) udawonetsa mtengo wocheperako wa 51 dB. Chabwino, popeza palibe zotayika pamawunivesite a mlongoti uwu, ndiye kuti mphamvu yamagetsi yamagetsi (VSWR) imasonyeza kufanana kwapakati pa 1,00 - 1,01 (kutsika kwa SWR graph), pamafupipafupi osankhidwa a 5740 MHz (otsika kuchokera ku ma transmitter omwe amapezeka).
Choncho, mphamvu zonse zing'onozing'ono zomwe zilipo zimatha kutulutsidwa muwailesi popanda kutaya, zomwe zinali zofunika pankhaniyi.
Pang'onopang'ono, nayi zida zowonjezera zomwe zidasonkhanitsidwa kuti zikhazikitsidwe m'nyumba ya mphaka:
Apa, kuwonjezera pa "otenthetsera" (mbale zazikulu ndi zonyezimira pansi), njira yakutali yoyatsa / yozimitsa idawonjezedwanso, mwa mawonekedwe a wailesi yakutali ndi gawo lolandirira ndi kutumizirana mauthenga, lokonzedwa kuti lizilumikizana pawailesi. 315 MHz osiyanasiyana.
Izi ndizofunikira kuti musamapangire mphaka wogona nthawi zonse ndi kuyatsa kwa LED komanso chosinthira pawayilesi, ngakhale chitakhala chofooka kwambiri ndipo chili kuseri kwa chitsulo chotchinga chachipinda chapamwamba.
Nyamayo iyenera kugona mwamtendere, popanda kuunikira kopanga, kamera yapafupi ya kanema kapena ma radiation oyipa omwe amalowa m'maselo amoyo athupi. Koma kwakanthawi kochepa, nthawi iliyonse mukapemphedwa, mutha kugwiritsa ntchito chiwongolero chakutali kuti mupereke mphamvu pakukhazikitsa makanema onse okhala ndi nyali zamtundu wa diode, onani mwachangu momwe mavidiyo amawonera, ndikuzimitsa nthawi yomweyo.
Kuchokera pakuwona kugwiritsa ntchito magetsi, izi ndizosankha zabwino kwambiri komanso zachuma.
Mzere wa LED wa ma diode 12 adadulidwa m'magawo awiri, amamatira ndi "kusokedwa" pamwamba ndi waya wamkuwa wowawa womwewo, kuti usang'ambe ndi chikwapu chomwe chingathe, ndipo magetsi aziwala ngati pakufunika:
Kamera ya kanema yokhala ndi chowulutsira mavidiyo ndi mizere iwiri ya LED yoyendetsedwa ndi chuma kudzera pazitsulo zochepetsera zomwe zilipo (390 Ohms iliyonse), komanso cholumikizira wailesi, zimangotenga 199 mA, ikayatsidwa, kuchokera pa sekondi imodzi. Gwero lamakono la 12-volt. Kumalo akutali, mumayendedwe oyimilira, mawayilesi okhawo amapezeka, omwe amangogwiritsa ntchito ma 7,5 mA okha, omwe ndi ang'onoang'ono kwambiri ndipo amabisika kumbuyo kwa kutayika kwa metering pamaneti.
Mawotchi otenthetsera magetsi samayatsanso pamanja. Kwa iwo, thiransifoma yotsika-pansi imalumikizidwa ndi thermostat yoyendetsedwa ndi wailesi, chowongolera chakutali chokhala ndi masensa omwe ali mnyumbamo. Chifukwa chake pakatentha kale, makina otenthetsera amangozimitsa ndikuyatsa pokhapokha kutentha kwakunja kutsika.
Kamera ya kanema idasankhidwa kuchokera ku kamera yopanda mawonekedwe, koma yokhala ndi chithunzithunzi chapamwamba cha 0,0008 lux.
Kuchokera ku aerosol ndidakutira ndi varnish ya polyurethane kuti mutetezeke mumlengalenga ndi kusintha kwa chinyezi, kapena ngakhale mvula yomwe ingathe.
Mlongoti wophimbidwa ndi kamera pambuyo pa varnish, mawonedwe akumbuyo. Pansipa mutha kuwona tepi yofiyira yomwe sinachotsedwebe, kuphimba kulumikizana kwa cholumikizira chachikulu:
Pa kamera ya kanema, ndinayenera kukonzanso mandala kuti ndigwire ntchito pafupi ndi mtunda wa 15-30 cm.
Gawo lokhazikitsidwa la zida (zokhala ndi mawaya) pabokosi lanyumba, musanatumize nyumba yonse kuchipinda chapamwamba:
Monga mukuonera, apa "denga" la bokosilo limalimbikitsidwa kuchokera mkati ndipo "amasokedwa" ndi mkuwa, ngati mphaka asankha kulumpha pamwamba ndikupondaponda "denga" la nyumbayo. Mulimonsemo, sipadzakhala tepi yokwanira pano, ngakhale itakhala yotsutsana ndi zowonongeka.
Mayesero omaliza a amphaka apakhomo, kuyatsa ndi kuyatsa mavidiyo, adawonetsa kupambana kovomerezeka kwa lingaliro lopangidwa:
1) Ndi Siamese:
2) Ndi tricolor:
Ulalo wa kanema, ndithudi, suli wa Full HD kusamvana, koma SD yokhazikika ya analogi (640x480), koma pakuwongolera kwakanthawi ndikokwanira. Palibe ntchito yowunika tsitsi lililonse; ndikofunikira kumvetsetsa ngati chinthucho chili ndi moyo.
Tsiku linafika loti akhazikitse nyumba yonse pamalo ogonawo, amene anali chipinda chapamwamba chapamwamba mβkhumbi lalingβono lokhala ndi poyatsira moto. Chipinda chapamwamba chinakhala chosasamalidwa, chinangomangidwa ndi misomali ndipo ndi momwemo. Ndinayenera kugwiritsa ntchito pliers kuchotsa misomali pafupifupi 50 yomwe ili mozungulira pamphepete mwa mapepala awiri a gable sheathing.
Ndinkayembekezera kuti mphakayo ndi wamantha ndipo nthawi yomweyo amathawa phokoso la "opaleshoni ya zida" ndi chipinda chapamwamba. Koma kunalibe! Anandithamangira, akulira mosimidwa, akusisima ndikuyesera kuvulaza zikhadabo. Zikuoneka kuti m'mbuyomu adamenyana ndi amphaka am'deralo kangapo ndipo m'nkhondo adadzipezera yekha malowa. Izi sizikudziwika.
Aka kanali koyamba kuwona mphanga wotere wa m'chipinda chapamwamba. Uwu ndi fumbi, ubweya wakale wagalasi, wopangidwa kuti ukhale wosalala. Zikuoneka kuti uyu si mphaka woyamba kukhala kumeneko. Kufupi ndi kumeneko kunali mulu wa nthenga za mbalame, mwachionekere mabwinja a nyama zodyedwa. Kuzungulira kuli magulu akale ndi akuda, fumbi lochuluka, nthenga ndi mafupa a mbalame zazing'ono, nthawi zambiri mawonekedwe osawoneka bwino komanso owopsa:
Nditayika nyumba ya mphaka mokhazikika pansi pa denga ndikulumikiza mawaya, ndidakhomerera chikwama chakale ndi zomangira zatsopano.
Kanemayo adakonzekera nthawi yomweyo kuti achotsedwe m'dera la "shading" lazitsulo, kotero kuti palibe chomwe chingasokoneze mafunde a wailesi omwe kale anali ofooka kwambiri omwe akuyenda pabwalo, ndikuwonekera kuchokera kumpanda, kulowa kudzera pawindo lotsegula mnyumbamo, wolandila ndi polojekiti. Chopatsiranacho chinali chokulungidwa ndi kutentha kwa kutentha ndi malekezero osindikizidwa ndikuyika pa mwendo wa mast kotero kuti panalibe zinthu zopangira zozungulira kuzungulira mlongoti pamtunda wa 1,5 - 2 Lambda. Mu chithunzi mungathe kuona mlongoti wokhotakhota, iwo amati, n'chifukwa chiyani mosasamala?. Patapita nthawi, tinayenera kutsegulanso nsonga, komanso kuteteza chotengeracho mosiyana ndikupinda mlongoti pakona yoyenera, komanso kuti titetezedwe ku mvula yamvula komanso mvula yamatalala ndi mphepo, yomwe nthawi zonse imagwa kuchokera mbali imodzi. Poganizira zinthu ziwiri nthawi imodzi, coaxial feeder idapindika, koma palibe chifukwa chokopera chithunzi chofananira.
Wowerenga wofuna kudziwa angazindikire, chifukwa chiyani munayenera kutsegulanso chipinda chapamwamba? Chifukwa nditadikirira masiku atatu ndikuyatsa nthawi ndi nthawi kuyang'anira mavidiyo, sindinapeze mphaka m'nyumba yatsopano. Mwina amangoopa kuyandikira kapena kuyang'ana mkati. Mwina anamva fungo la amphaka a anthu ena mβbokosilo. Ndipo mwina mphaka sanamvetsetse kuti iyi inali nyumba yokhala ndi bedi ndipo mutha kulowamo mwa kungosuntha chivundikiro cha kagawo ndi mphumi yanu. Chifukwa sichidziwika.
Ndinaganiza zomunyengerera kupyolera mufungo lazakudya. Chabwino, osachepera chifukwa cha kuzolowerana, muloleni amvetse kuti palibe choopsa m'bokosi, ndi kuti ndizosangalatsa kwenikweni kumeneko. Ndikagona ndekha, koma ndikufunika kugwira ntchito. π
Nthawi zambiri, nditatsegulanso mwayi wopita kuchipinda chapamwamba, ndisanalowe m'bokosilo komanso mukhonde la bokosilo, komanso pabedi, ndidaponya ma granules a chakudya ndi fungo labwino.
Hurray, chinyengo chokomacho chinagwira ntchito!
Theka la ola pambuyo pake, chinthu chofunidwacho, mosamala kwambiri komanso pang'onopang'ono, adapeza khomo la nyumbayo, adayendera zonse (ndipo kangapo), kudya zabwino zonse kumeneko.
(pachithunzichi tsopano pali chowunikira chosiyana, chokhala ndi mawailesi omangidwa komanso zolembedwa zobiriwira)
Chifukwa chake, mphaka wapachipinda chapamwamba tsopano ali ndi "nyumba" yokhala ndi zopindika za Hi-Tech, ndipo ndili ndi chowonjezera mu karma yanga pazantchito zabwino, komanso, kuthekera kowonera kanema wakunja, zomwe zilipo komanso momwe. Zingakhale zotheka kujambula mavidiyo omwe adalandira ndikukonzekera kuwulutsa kwake pa intaneti. Ingakhale webcam.
Koma popeza palibe chochititsa chidwi apa, ndipo kachiwiri, palibe chifukwa chosokoneza mphaka, ndiye kuti palibe bungwe lojambula ndi kuwulutsa.
Koma kulibenso mbewa, ndipo izi ndizoyenera kwa mmodzi wa ife, ndi mphaka uyu.
