Kutshanje ndiye ndaqaphela ukuba ikati ebhityileyo kwaye yoyikeka kakhulu, enamehlo alusizi ngonaphakade, yahlala kwigumbi eliphezulu lendlu ...
Akazange aqhagamshelane, kodwa wasibukela kude. Ndaye ndagqiba ekubeni ndimphathe ngokutya kwe-premium, nto leyo yethu yasekhaya i-cat-face iphakamisa. Kwanasemva kweenyanga ezimbini zokuphatha, ikati isakuphepha yonke imizamo yokunxibelelana nayo. Mhlawumbi wayeyifumene kubantu bangaphambili, nto leyo eyakhokelela ekubeni azive eneentloni.
Njengoko bethetha, ekubeni u-Mohammed engayi entabeni, intaba ngokwayo iya kuza ku-Mohammed. Ngokumalunga noshintsho oluzayo lwexesha kunye nemozulu ebandayo engenakuphepheka, ndagqiba ekubeni ndimakhele uhlobo oluthile "lwendlu", ndibeke kwintsimi yakhe, oko kukuthi, kwi-attic.
Isiseko sendlu yibhedi eyenziwe kwibhokisi ephindwe kabini ukusuka kwimango yaseHainan. Ukuphinda kabini kuxa ibhokisi ifakwe kwisiciko esiguqulweyo ukusuka kwibhokisi enye. Isiqingatha ngasinye siphindwe kabini, ngoko ke ibhokisi ijika ibe yi-quadruple kunye nokomelela okwandisiweyo. AmaTshayina ayazi kakhulu ngeebhokisi, njengoko ubungakanani bebufanelekile kwiikati. π Phakathi kweengqimba, ndibeke umgca we-laminate kwibhokisi ye-insulation eyongezelelweyo ye-thermal. Emva koko, ndibeka iileyile ezi-2 zerabha yamagwebu esentimitha emazantsi, kwaye ngaphezulu - itawuli endala ye-terry esongelwe kathathu.
Ukwazi ukuba yintoni na "inyathelo lobisi" kunye nokukhululwa kweenzipho, kwaye ukuba nayiphi na indawo yokulala iya kushwabana ngokuhamba kwexesha, ndithunge yonke itawuli yomithathu ukuya ebhokisini. Ngaphezu koko, akazange ayithunge ngemicu, enokuhlafunwa lula okanye ikrazulwe zizizipho, kodwa ngocingo lobhedu (olujikajikayo) olufakwe kwivarnish, ukuya kuthi ga kwi-1,2 mm ubukhulu. Ewe, ibukhali, kodwa ikwachasene ne-vandal, ukusuka kwiinzipho zekati okanye amazinyo.
Ndisebenzisa indlela efanayo, ndathunga zonke iikona ukuze indawo yokulala igcine imilo yayo yokubeka, nangona kukho naluphi na ukuxhatshazwa okuvela kumhlali.
Kodwa akwanele nje ukubeka ibhedi ethambileyo, kuba ebusika kukho iidrafti zeqhwa kwi-attic, kunye nokushisa okufanayo nangaphandle. Oku kuthetha ukuba umsebenzi uvele wokudala into efana ne "dome" ejikeleze ibhedi yokugcina ubushushu obuphuma kwikati. Ukwenza oku, ibhedi elungiselelwe ifakwe ngaphakathi kwebhokisi enkulu.
Kwindonga yecala lebhokisi langaphandle ndinqumle uhlobo "lwengcango", ndizivala ngokwalo isicatshulwa ukuze ubushushu bungaphumi kakhulu.
Njengoko umsebenzi uqhubela phambili, ubuso bekati yasekhaya bukwazile ukuzama ikhaya elithambileyo izihlandlo ezininzi:
Bakonwabele kakhulu ukunyathela ebhedini, okwathi emva kwemizuzu emi-5 kwalalisa wonke umntu:
Ewe, ke, kuba sinokugcina ubushushu obujikeleze umhlali sisebenzisa umjikelezo ovaliweyo wangaphandle, kutheni ungavelisi ubushushu kanye apho, ukuze ikati ehlala kuyo ikwazi ukugcina ukulahleka kobushushu emzimbeni wakhe. Ukwenza oku, imigangatho emibini eyongezelelekileyo yekhadibhodi eshinyeneyo kunye ne-thermal insulation yafakwa ezantsi kwebhokisi enkulu, phakathi kwazo ezimbini ezisebenzayo, izinto zokufudumeza zobushushu ezenziwe ngentambo ye-multi-core constantan zafakwa. Zaziyilelwe unikezelo lwamandla kwi-USB, oko kukuthi, 5 volts. Emva kokuba ndiwadibanise kuluhlu, ndiwaguqulele kumandla ukusuka kwi-9 - 10 volts, kunye nokusetyenziswa kwangoku malunga ne-1 Ampere, eya kusinika amandla okufudumala kwe-9-10 watts. Kwaye oku sele kuninzi kumthamo omncinci wokufudumeza.
Ekubeni isilwanyana siyi-priori engafundanga, sinokuhlafuna ngokwethiyori ngentambo yamandla kwiphedi yokufudumeza kwibhokisi. Kwaye ukuba kunjalo, ngoko kufuneka ucinge malunga nomba wokuqinisekisa ukhuseleko oluqinisekisiweyo lwempilo yezilwanyana, ukusuka ekutshitshisweni kombane. Ukufezekisa lo msebenzi, ndiyekile ukusetyenziswa kweeyunithi ze-pulse zanamhlanje kwaye ndakhetha uhlobo oludala lwe-transformer power supply, kunye ne-galvanic isolation kwi-network (ayizange ifakwe kwiifoto). Nangona iijeneretha ze-pulse nazo zine-decoupling, zisa "pinch" kancinane, umzekelo ngokumalunga nesekethe yokufudumeza.
Ewe, ekubeni sangena endlwini "neentsimbi kunye neempempe", ndacinga ukuba ndiza kufaka ibhokisi kwi-attic, ndibethelele i-gable nge-sheathing kunye nokuhamba kakuhle. Kuthekani ukuba senza uhlobo oluthile lokujonga ividiyo? Kuya kuba mnandi ukufumanisa ukuba ikati iya kuthatha inzuzo yonke ingcamango? Ndandingafuni ukuqhuba intambo yevidiyo; yayiza kufuna umfanekiso omninzi, ndiye ndagqiba ekubeni ndibhenele ekusasazeni ividiyo ngesikhululo sikanomathotholo. Ndakhe ndadibana ne-5,8 GHz ividiyo etshisiweyo, umnini wayo wakwazi ukuyitshisa ngandlela thile. Ngokukodwa, inqanaba lemveliso ye-RF amplifier yajika yatshiswa. Emva kokuba ndisuse i-microcircuit yenqanaba lesiphumo esingalunganga, kunye nayo yonke i-SMD "yokubhobhoza" ejikeleze kuyo, ndidibanise imveliso yeqonga lokuhambisa ividiyo kunye ne-coaxial "bypass" kwisinxibelelanisi se-SMA se-antenna. Ukusebenzisa i-Arinst 23-6200 MHz i-reflectory ye-vector, ndilinganise i-coefficient ye-reflection ye-S11 kwaye ndaqinisekisa ukuba i-impedance ye-output kwi-frequencies yokusebenza ihlala ngaphakathi kwemida eyamkelekileyo, malunga ne-50 Ohms.
Ukufuna ukwazi kungene, yintoni ke ngoko amandla okwenene aloo vidiyo "ethenwe" ehambisa ividiyo, ukuba uyondla i-eriyali ngokuthe ngqo ukusuka "kwi-boost", oko kukuthi, ngaphandle kwe-amplifier yamandla konke konke? Ndithathe imilinganiselo ndisebenzisa imitha yamandla ye-microwave echanekileyo i-Anritsu MA24106A, kuluhlu olufanelekileyo ukuya kwi-6 GHz. Awona mandla elona tshaneli lisezantsi losasazo, i-5740 MHz, yayiyi-18 milliwatts kuphela (ngaphandle kwe-600 mW). Oko kukuthi, kuphela i-3% yamandla angaphambili, encinci kakhulu, kodwa nangona kunjalo iyamkeleka.
Ekubeni kwenzeka ukuba amandla e-microwave afumanekayo ayanele, ngoko ukuhanjiswa okuqhelekileyo kwevidiyo kuya kufuneka usebenzise i-antenna engcono.
Ndifumene i-eriyali endala yale bhendi ye-5,8 GHz. Ndidibene ne-eriyali yohlobo lwe "helical wheel" okanye "clover", oko kukuthi, i-eriyali ene-spatially circular polarization vector, ngakumbi kwicala lasekhohlo lokujikeleza. Kwiindawo zasezidolophini, kulungile ukuba umqondiso awuyi kukhutshwa nge-polarization yomgca, kodwa isetyhula. Oku kuya kuququzelela kwaye kuphuculwe umfanekiso wokulwa nokuphazamiseka okungenakuphepheka ekufumaneni okubangelwa ukubonakaliswa kwemiqobo ekufutshane kunye nezakhiwo. Kwawona mfanekiso wokuqala, kwikona esezantsi ekunene, ubonisa ngokucwangcisekileyo ukuba injani na i-polarization yesetyhula ye-propagation vector ye-electromagnetic radio wave.
Ndisebenzisa isihlalutyi senethiwekhi ye-vector esanda kulungiswa (isixhobo se-VNA), ndilinganise i-VSWR kunye nokuphazamiseka kwale antenna, ndiye ndafumana unxunguphalo, kuba baye babonakala bephakathi kakhulu. Ngokuvula izigqubuthelo ze-eriyali kunye nokusebenza ngolungelelwaniso lwendawo yazo zonke ii-vibrators ezi-4 apho, kunye nemeko eyimfuneko yokuthathela ingqalelo ukunyanzeliswa kwezigqubuthelo zeplastiki, sakwazi ukususa ngokupheleleyo i-parasitic reactivity yazo zombini i-capacitive kunye ne-inductive nature. Kwangaxeshanye, kwakunokwenzeka ukuqhuba ukuchasana okusebenzayo kwindawo ephakathi ye-Wolpert-Smith umzobo wesetyhula (kanye i-50 Ohms), kwi-frequency ekhethiweyo yesitishi esisezantsi se-transmitter ekhoyo, oko kukuthi kwi-frequency ecwangcisiweyo yokusasaza. 5740 MHz:
Ngokuhambelanayo, inqanaba lelahleko ebonakalisiweyo (kwigrafu ye-logarithmic magnitude ye-avareji) ibonise ixabiso lemicroscopic lika-minus 51 dB. Ewe, kuba akukho lahleko kwi-resonance frequency yale antenna, ke umlinganiselo we-voltage stand wave wave (VSWR) ubonisa ukuhambelana okufanelekileyo ngaphakathi kwe-1,00 - 1,01 (igrafu esezantsi ye-SWR), ngexesha elifanayo elikhethiweyo le-5740 MHz (ephantsi ukusuka amajelo osasazo akhoyo).
Ngaloo ndlela, onke amandla amancinci akhoyo anokukhutshwa emoyeni werediyo ngaphandle kokulahlekelwa, eyona nto ifunekayo kule meko.
Kancinci, nantsi iseti yezixhobo ezongezelelweyo ezidityaniselwe ukufakwa kwindlu yekati:
Apha, ukongeza kwi "warmers" (iipleyiti ezinkulu kunye ezicwebezelayo ezantsi), inkqubo ekude yokucima / yokucima nayo yongezwa, ngendlela yolawulo olukude lwerediyo kunye neyunithi yokwamkela kunye nokuhanjiswa, elungiselelwe unxibelelwano lwerediyo ehambelanayo. ububanzi 315 MHz.
Oku kuyimfuneko ukuze ungaphembeleli rhoqo ikati eleleyo kunye nesibane se-LED kunye nesitshixo sosasazo lwerediyo, nokuba ibuthathaka kakhulu kwaye ibekwe ngasemva kwentsimbi ye-attic gable.
Isilwanyana kufuneka silale ngoxolo, ngaphandle kokukhanyisa okwenziweyo, ikhamera yevidiyo ekufutshane okanye imitha yerediyo eyingozi engena kwiiseli eziphilayo zomzimba. Kodwa ixesha elifutshane, nangaliphi na ixesha xa uceliwe, ungasebenzisa isilawuli kude ukuze unikeze amandla kuyo yonke isethingi yevidiyo enezibane ze-diode strip, ubone ngokukhawuleza ukuba imiboniso yevidiyo injani, kwaye ucime ngokukhawuleza inkqubo.
Ukususela kumbono wokusetyenziswa kombane, oku kwakhona kukhetho olufanelekileyo kunye noqoqosho.
Umtya we-LED we-12 diode wanqunyulwa ube ziinxalenye ezimbini, wancamathelwa kwaye "wathungwa" phezulu kunye nocingo oluqatha olufanayo lobhedu, ukuze ungakrazuli kuhlaselo olunokwenzeka, kwaye izibane ziya kukhanya apho zifuneka khona:
Ikhamera yevidiyo ene-video transmitter kunye neperi ye-LED strips enikwe amandla kuqoqosho ngokusebenzisa iperisi yangoku yokunciphisa (390 Ohms nganye), kunye ne-radio switch receiver, idla kuphela i-199 mA, xa ivuliwe, ukusuka kwisekondi. I-12-volt umthombo wangoku. Kwimeko engaphandle, kwimowudi yokulinda, kuphela iswitshi yerediyo ekhoyo, ngokusetyenziswa kokulinda kwe-7,5 mA kuphela, encinci kakhulu kwaye igqunywe ngokusisiseko ngokuchasene nemvelaphi yelahleko ekusetyenzisweni kwemitha kwinethiwekhi.
Iipads zokufudumeza zombane nazo azivuli ngesandla. Kubo, i-transformer ye-step-down ixhunywe nge-thermostat elawulwa ngumsakazo, i-remote control kunye ne-sensors ekhoyo endlwini. Ngoko xa sele ishushu, inkqubo yokufudumala iya kucima ngokuzenzekelayo kwaye ivule kuphela xa ukushisa kwangaphandle kwehla.
Ikhamera yevidiyo ikhethwe kwikhamera engenafreyimu, kodwa ine-photosensitivity ephezulu ye-0,0008 lux.
Ukusuka kwi-aerosol ndiyiqabe nge-polyurethane ivanishi yokukhusela umoya kunye nokutshintsha komswakama, okanye imvula enokwenzeka.
I-antenna egqunyiweyo kunye nekhamera emva kwe-varnishing, ukujonga ngasemva. Ngezantsi ungabona iteyiphu ebomvu engekasuswa, igquma abafowunelwa besiqhagamshelo esingundoqo:
Kwikhamera yevidiyo, kwafuneka ndiphinde ndigxininise i-lens ukuze ndisebenze kwindawo ekufutshane, kumgama omkhulu we-15-30 cm.
Inxalenye exhonyiweyo yezixhobo (kunye neengcingo) kwindlu yebhokisi, ngaphambi kokuthumela sonke isakhiwo kwi-attic:
Njengoko ubona, apha "i-ceiling" yebhokisi iqiniswa ngaphakathi kwaye "ihlanganiswe" ngobhedu, xa kwenzeka ukuba ikati inqume ukutsiba phezulu kwaye inyathele "uphahla" lwendlu. Kwimeko nayiphi na into, akuyi kuba ne-tape eyaneleyo apha, nokuba i-anti-vandal-reinforced.
Iimvavanyo zokugqibela kwiikati zasekhaya, kunye nokukhanya kunye nokuhanjiswa kwevidiyo kuvuliwe, kubonise impumelelo eyamkelekileyo yengcamango efunyenweyo:
1) NgeSiamese:
2) Nge-tricolor:
Ikhonkco levidiyo, ngokuqinisekileyo, ayikho i-Full HD isisombululo, kodwa i-SD ye-analog eqhelekileyo (640x480), kodwa ukulawula okufutshane kunokwaneleyo. Akukho msebenzi wokuhlola zonke iinwele; kubalulekile ukuqonda ukuba into yokujongwa iyaphila na.
Yafika imini yokufakwa kweso sakhiwo siphela kwindawo yokulala, eyayiliphahla elidala kwishedi encinane eneziko lasekuhlaleni. I-attic yabonakala ingagcinwanga, yayiboshwe nje ngezikhonkwane kwaye yiloo nto. Kuye kwafuneka ndisebenzise iipleyiti ukususa malunga nezikhonkwane ezingama-50 ezibekwe kufutshane nomjikelezo wephepha ngalinye lamaphepha amabini egable sheathing.
Ndandilindele ukuba ikati ineentloni kwaye ngokukhawuleza yayiza kubaleka ingxolo "yotyando lwezixhobo" olunjalo kunye ne-attic. Kodwa yayingekho! Wandigxalathelana, ebhomboloza ephelelwe lithemba, efutha ezama ukonzakalisa uzipho. Kuyabonakala ukuba wayekhe walwa neekati zasekuhlaleni ngaphezu kwesihlandlo esinye kwaye emadabini wazifumanela le ndawo yokuhlala. Oku akwaziwa.
Ndiyaqala ukubona umngxuma onje wekati ephahleni. Oku kunothuli kakhulu, uboya beglasi obudala, budityaniswe bukwimo esicaba. Kubonakala ngathi le asiyokati yokuqala ehlala apho. Kufuphi kwakukho imfumba yeentsiba zeentaka, ekucaca ukuba yayizintsalela zexhoba elityiweyo. Ukujikeleza kukho iqoqo leentambo ezindala kunye nezimnyama, uthuli oluninzi, iintsiba kunye namathambo eentaka ezincinci, ngokubanzi umbono ongathandekiyo nowothusayo:
Emva kokuba ndibeke indlu yekati ngokuzinzileyo phantsi kophahla ndaza ndaqhagamshela iingcingo, ndayijija i-casing endala ngezikrufu.
Umshicileli wevidiyo wacwangciswa ngoko nangoko ukuba asuswe kwindawo enentsimbi "yomthunzi", ukuze kungabikho nto iphazamisana namaza kanomathotholo asele ebuthathaka kakhulu atyhutyha eyadini, kwaye abonakaliswe elucingweni, angene ngefestile evula ifestile endlwini, umamkeli ngemonitha. I-transmitter ngaphambili yayisongelwe ngokushwabana kobushushu kunye neziphelo ezitywiniweyo kwaye yaxhonywa emlenzeni wemasti ukuze kungabikho zixhobo zolwakhiwo ezijikeleze i-eriyali kumgama we-1,5 - 2 Lambda. Kulo mfanekiso ungabona i-eriyali egoso, bathi, kutheni i-sloppy? Emva kwexeshana, kuye kwafuneka ukuba sivule i-pediment kwakhona, kunye nokukhusela isidluliseli ngokwahlukileyo kwaye sigobe i-eriyali kwi-engile efanelekileyo, kunye nokukhusela kwimvula enethayo kunye nemvula yesichotho ngomoya, osoloko uwela ngokungqongqo kwicala elinye. Ukuthathela ingqalelo izinto ezimbini ngexesha elinye, i-coaxial feeder yayigobile, kodwa akukho sizathu sokuphinda ifoto efanayo.
Umfundi othanda ukwazi unokubona, kutheni kufuneke uvule i-attic kwakhona? Kuba emva kokulinda iintsuku ezintathu kwaye ngamaxesha athile ndivula inkqubo yokubeka iliso yevidiyo, andizange ndifumane ikati kwindlu entsha. Mhlawumbi woyika ukusondela okanye ukukhangela ngaphakathi. Mhlawumbi wayeva ivumba leekati zabanye abantu ebhokisini. Kwaye kusenokwenzeka ukuba ikati yayingaqondi nokuba le yindlu enebhedi kwaye ungangena apho ngokutyibilika nje isiciko sendawo ngebunzi lakho. Isizathu asaziwa.
Ndaqonda mandimtsale ngevumba lezinto ezityiwayo. Ewe, ubuncinci ngenxa yokuqhelanisa, makaqonde ukuba akukho ngozi kwibhokisi, kwaye kumnandi ngokwenene apho. Bendizolala mna, kodwa kufuneka ndiphangele. π
Ngokubanzi, emva kokuvula kwakhona ukufikelela kwi-attic, ngaphambi kokungena ebhokisini kunye ne-corridor yebhokisi ngokwayo, kunye nasebhedini, ndaphosa ezinye iigranules zokutya kunye nevumba elitsha.
Hurray, iqhinga elimnandi lisebenzile!
Isiqingatha seyure kamva, into efunwayo, ngokucokisekileyo kunye namanyathelo amancinci, yafumana umnyango wendlu, wayityelela ngokupheleleyo (kwaye ngaphezu kweyodwa), idla zonke izinto ezilungileyo apho.
(kwifoto ngoku kukho imonitha eyahlukileyo, enerediyo ezakhelwe ngaphakathi kunye nemibhalo eluhlaza)
Ke, ikati ye-attic ngoku ine "indlu" ene-Hi-Tech twist, kwaye ndine-plus kwi-karma yam ngesenzo esihle, kwaye ukongeza, ukuba nokwenzeka kokujonga ividiyo elawulwa ngaphandle, yintoni ekhoyo kwaye njani. Kuya kwenzeka ukuba kufakwe ividiyo efunyenweyo kwaye uququzelele usasazo lwayo kwinethiwekhi. Iya kuba yikhamera yewebhu.
Kodwa ekubeni akukho nto inomdla ngokusisiseko apha, kwaye okwesibini, akukho mfuneko yokuphazamisa ikati, ngoko akukho ntlangano yokubamba ngokusasazwa.
Kodwa azisekho iimpuku, kwaye ngokuqinisekileyo oku kukufanelekela komnye wethu, kunye nale kati.
Intsimi yethu kunye nentsimi yabamelwane bethu iye yacocwa ngokupheleleyo.
Ngoko ke ikati ifanelekele ngokupheleleyo ibhedi ecocekileyo, efudumeleyo nenokuthula ukuze iphumle kuyo.
Makahlale apho ixesha elide kangangoko, ethuthuzelekile noxolo.
Ithamsanqa kuMtyholi oneentloni ngamehlo alusizi:
