Nguva pfupi yadarika ndakaona kuti katsi yakaonda uye inonyara kwazvo, ine maziso akasuwa nekusingaperi, yakanga yagara mukamuri remba ...
Haana kuita contact, asi akatitarisa ari kure. Ndakafunga kumurapisa nechikafu chemhando yepamusoro, izvo zviso zvekatsi yedu yemumba zvinokwidza. Kunyangwe mushure memwedzi miviri yekubatwa, katsi yakaramba ichidzivisa zvese kuedza kumubata. Zvichida akaiwana kuvanhu kare, izvo zvakatungamirira kukutya kwakadaro.
Sezvavanotaura, sezvo Mohammed asingaendi kugomo, gomo pacharo rinouya kuna Mohammed. Maererano nekuchinja kuri kuuya kwemwaka uye kusingadzivisiki kutonhora kwemamiriro okunze, ndakasarudza kumuvakira imwe rudzi rwe "imba", ndichiisa pandima yake, kureva, muimba yepamusoro.
Nheyo yeimba mubhedha wakagadzirwa kubva kubhokisi reviri kubva kuHainan mango. Kaviri ndipo panopinzwa bhokisi muvharo yakatenderedzwa kubva mubhokisi rimwechete. Hafu imwe neimwe yakapetwa kaviri, saka bhokisi rinoshanduka kuva quadruple uye yekuwedzera simba. VaChinese vanoziva zvakawanda nezvemabhokisi, sezvo ukuru hwaive hwakakwana kune katsi. π Pakati pematanho, ndakaisa laminate lining mubhokisi rekuwedzera kupisa kwemafuta. Tevere, ndinoisa 2 zvidimbu zve centimita furo rabha pazasi, uye pamusoro - tauro rekare reterry rakapetwa mumatatu.
Ndichiziva kuti "nhanho yemukaka" ndeyei nekuburitswa kwezvikwambo, uye kuti chero chekurara chinozopwanyika sei nekufamba kwenguva, ndakasonera zvidimbu zvitatu zvetauro kusvika kubhokisi. Uyezve, haana kuisona neshinda, iyo yaigona kutsenga nyore nyore kana kubvarurwa nembavha, asi newaya yemhangura (inomonereka) muvhanish insulation, yakakora 1,2 mm. Hongu, ine hutsinye, asi zvakare inopesana-vandal, kubva kumakumbo ekati kana mazino.
Ndichishandisa nzira yakafanana, ndakasonera makona ese kuitira kuti mubhedha uchengetedze chimiro chayo chekuisa, kunyangwe chero kushungurudzwa kubva kumugari-mugari.
Asi hazvina kukwana kungoisa mubhedha wakapfava, nekuti munguva yechando kune chando dhizaini muattic, ine tembiricha yakafanana neyekunze. Izvi zvinoreva kuti basa rakamuka kugadzira chinhu chakaita se "dome" chakatenderedza mubhedha kuchengetedza kupisa kunobva pakatsi. Kuti uite izvi, mubhedha wakagadzirirwa wakaiswa mukati mebhokisi guru.
Pamadziro emadziro ebhokisi rekunze ndakacheka rudzi rwe "gonhi", ndichizvivhara pachedu kuitira kuti kupisa kurege kupukunyuka zvakanyanya.
Sezvo basa richifambira mberi, zviso zvemukati zvekatsi zvakakwanisa kuedza paimba yakapfava yakadaro kakawanda:
Vainyatsonakidzwa nekutsika-tsika pamubhedha, izvo mukati memaminitsi mashanu zvakabva zvaita kuti munhu wese arare:
Zvakanaka, zvakanaka, sezvo tichigona kuchengetedza tembiricha yakatenderedza mugari tichishandisa perimeter yakavharwa nekunze, saka wadii kugadzira kupisa ipapo, kuitira kuti katsi inogara ichengetedze kurasikirwa kwekupisa mumuviri wake. Kuti uite izvi, mamwe maviri akaturikidzana eakakora kadhibhodhi ane kupisa kwekupisa akaiswa pazasi pebhokisi hombe, pakati payo maviri anoshanda, ekupisa kupisa zvinhu zvakagadzirwa ne-multi-core constantan cable yakaiswa. Vakanga vakagadzirirwa magetsi kubva USB, kureva, 5 volts. Sezvo ndakavabatanidza munhevedzano, ndakavashandura kuva simba kubva ku9 - 10 volts, nekushandiswa kwemazuva ano kwe1 Ampere, iyo yaizotipa simba rekupisa re9-10 watts. Uye izvi zvatowanda kune vhoriyamu diki yekudziya.
Sezvo mhuka iri priori isingagoni kuverenga, inogona kutsenga kuburikidza netambo yemagetsi yekudziya pad mubhokisi. Uye kana zvakadaro, saka iwe unofanirwa kufunga nezvenyaya yekuvimbisa kuchengetedzwa kwakachengeteka kwehutano hwemhuka, kubva pane zvinogona kuitika magetsi. Kuti ndiite basa iri, ndakasiya kushandiswa kwemazuva ano pulse units uye ndakasarudza yekare-modhi yemhando yemagetsi ekushandura magetsi, ine galvanic isolation kubva kune network (yaisabatanidzwa mumifananidzo). Kunyange zvazvo majenareta emagetsi anewo decoupling, achiri "pinch" zvishoma, semuenzaniso maererano nemhepo inopisa.
Zvakanaka, sezvo takapinda mumba ne "mabhero nemuridzo", ndakafunga kuti ndichaisa bhokisi muimba yepamusoro, roverera gable kumashure nesheathing uye zvakanaka. Ko kana tikaita imwe mhando yekutarisa vhidhiyo? Zvichave zvinonakidza kuziva kana katsi ichatora mukana weiyo pfungwa yese? Ini ndanga ndisingade kumhanyisa vhidhiyo tambo; yaizoda yakawanda yemifananidzo, saka ndakafunga kuita zvekufambisa vhidhiyo pachiteshi cheredhiyo. Ndakambosangana neyakapiswa-kunze 5,8 GHz vhidhiyo transmitter, muridzi wayo neimwe nzira akakwanisa kuipisa. Kunyanya, iyo yekubuda nhanho yeRF simba amplifier yakave yakapiswa kunze. Ndabvisa iyo yakashata yekubuda nhanho microcircuit, pamwe neiyo SMD "pombi" yakaitenderedza, ndakabatanidza kubuda kweiyo vhidhiyo transmitter drive nhanho necoaxial "bypass" kune SMA inobuda yekubatanidza yeantenna. Ndichishandisa Arinst 23-6200 MHz vector reflectometer, ndakayera iyo reflection coefficient yeS11 uye ndakaita shuwa kuti iyo impedance yekubuda pamhepo yekushanda yakaramba iri mukati memiganhu inogamuchirika, yakatenderedza 50 Ohms.
Kuda kuziva kwakapinda mukati, chii zvino isimba chairo reiyo "castrated" vhidhiyo transmitter, kana iwe ukadyisa antenna zvakananga kubva ku "boost", kureva kuti, isina simba amplifier zvachose? Ndakatora zviyero ndichishandisa chaiyo microwave simba mita Anritsu MA24106A, muchikamu chakakodzera kusvika ku6 GHz. Iyo chaiyo simba pane yakaderera frequency chiteshi cheiyo transmitter, 5740 MHz, yaingova 18 milliwatts (kunze kwe600 mW). Ndiko kuti, 3% chete yesimba rakapfuura, iro ridiki kwazvo, asi zvakadaro rinogamuchirwa.
Sezvo zvichiitika kuti simba rinowanikwa re microwave harina kukwana, saka kune yakajairika kutapurirana kwevhidhiyo rwizi uchafanirwa kushandisa iri nani antenna.
Ndakawana antenna yekare yeiyi 5,8 GHz bhendi. Ndakasangana neantenna yemhando ye "helical vhiri" kana "clover", kureva, antenna ine spatially denderedzwa polarization vector, kunyanya kuruboshwe nzira yekutenderera. Mumadhorobha, zvakatonaka kuti chiratidzo hachizobuditswa nemutsara polarization, asi denderedzwa. Izvi zvichabatsira nekuvandudza mufananidzo wekurwisana nekukanganiswa kusingadzivisiki pakugamuchira kunokonzerwa nekufungisisa kubva kune zvipingamupinyi zviri pedyo uye zvivako. Mufananidzo wekutanga, mukona yezasi yekurudyi, schematically inoratidza kuti denderedzwa polarization yepropagation vector ye electromagnetic radio wave inoita sei.
Ndichishandisa ichangobva calibrated vector network analyzer (VNA mudziyo), ndayera iyo VSWR uye impedance yeiyi antenna, ndakasangana nekuora mwoyo, sezvo ivo vakaratidza kuve vepakati. Nekuvhura zvivharo zveantenna uye nekushanda nekurongeka kwenzvimbo kwese 4 vibrators ipapo, nemamiriro akakosha ekufunga nezvekupinda kwemapurasitiki evhavha, takakwanisa kubvisa zvachose parasitic reactivity yezvose zviri zviviri capacitive uye inductive hunhu. Panguva imwecheteyo, zvaigoneka kutyaira kupikisa kunoshanda kusvika pakati peiyo Wolpert-Smith denderedzwa dhiyagiramu (chaiyo 50 Ohms), panguva yakasarudzwa frequency yeyakaderera chiteshi cheiyo iripo transmitter, iyo panguva yakarongwa nhepfenyuro frequency. 5740 MHz:
Saizvozvo, mwero wekurasikirwa kwakaratidzwa (paavhareji logarithmic magnitude graph) yakaratidza kukosha kwe microscopic ye minus 51 dB. Zvakanaka, sezvo pasina kana kurasikirwa paresonance frequency yeiyi antenna, ipapo iyo voltage standing wave ratio (VSWR) inoratidza yakakodzera kuenderana mukati me1,00 - 1,01 (yakaderera SWR graph), panguva imwechete yakasarudzwa frequency ye5740 MHz (yakaderera kubva iripo transmitter chiteshi).
Nokudaro, simba rose duku rinowanikwa rinogona kubudiswa mumhepo yeredhiyo pasina kurasikirwa, izvo zvaidiwa munyaya iyi.
Zvishoma nezvishoma, heino seti yezvimwe zvishongedzo zvakaunganidzwa kuti zvigadzirwe muimba yekati:
Pano, kuwedzera kune "warmers" (mahwendefa makuru uye anopenya pazasi), kureba kwe / kudzima system yakawedzerwawo, muchimiro cheredhiyo remoti control uye yekugamuchira uye relay unit, yakagadzirirwa kutaurirana redhiyo mukati. chiyero che 315 MHz.
Izvi zvinodikanwa kuitira kuti usarambe uchifurira katsi yakarara ine mwenje we LED uye inobatidzwa paredhiyo transmitter, kunyangwe isina kusimba zvakanyanya uye iri kuseri kwesimbi yakavharwa yeattic gable.
Mhuka yacho inofanira kurara murunyararo, isina chiedza chekugadzira, kamera yevhidhiyo iri pedyo kana mwaranzi inokuvadza yeredhiyo inopinda mumasero mapenyu omuviri. Asi kwenguva pfupi, chero nguva pakukumbira, unogona kushandisa remote control kuti upe simba kune yese vhidhiyo setup ine diode strip mwenje, kurumidza kuona kuti vhidhiyo inoratidzwa sei, uye nekukasira kudzima system.
Kubva pakuona kwekushandiswa kwemagetsi, iyi ndiyowo sarudzo yakakwana uye yehupfumi.
Mutsetse we LED we 12 diode wakachekwa kuita zvikamu zviviri, wakanamirwa uye "wakasonerwa" pamusoro newaya yakakasharara yemhangura, kuitira kuti isabvarura kubva pakurwiswa kweclaw, uye mwenje yaizopenya painoda:
Vhidhiyo kamera ine vhidhiyo transmitter uye peya ye LED mitsetse inopihwa simba rehupfumi kuburikidza neazvino-zvinomisikidza resistors (390 Ohms imwe neimwe), pamwe neredhiyo switch inogamuchira, inoshandisa chete 199 mA, kana yabatidzwa, kubva sekondi. 12-volt ikozvino sosi. Mune iyo off state, mune yekumira modhi, chete redhiyo switch iripo, ine yekumira yekushandiswa kwe7,5 mA chete, iyo idiki kwazvo uye yakanyatso kuvharwa nekumashure kwekurasikirwa mukushandiswa kwemamita kubva kunetiweki.
Magetsi ekudziya mapedhi zvakare haabatike nemaoko. Kwavari, nhanho-pasi-transformer yakabatana kuburikidza neredhiyo-inodzorwa thermostat, iyo kure kure ine sensors iyo iri mumba. Saka kana kwave kutodziya, iyo yekudziya system inodzima nekubatidza chete kana tembiricha yekunze yadonha.
Vhidhiyo kamera yakasarudzwa kubva kune isina furemu kamera, asi ine yakaringana yakakwira photosensitivity ye0,0008 lux.
Kubva pane aerosol ndakaiputira nepolyurethane varnish yekudzivirira kwemuchadenga uye kushanduka kwehunyoro, kana kutogona kunaya kwemvura.
Yakavharwa antenna uye kamera mushure mevarnishing, kumashure kwekuona. Pazasi iwe unogona kuona iyo dzvuku tepi isati yabviswa, ichivhara mabikirwo eiyo main connector:
