Kungaba omunye wemiklamo yakudala kakhulu kwezesayensi: ibhokisi lokhuni elimhlophe qhwa, elithandwayo. Kungani, enkathini yamasathelayithi nama-radar, sisathembela kuyo ukuze isitshele iqiniso eliyisisekelo ngesimo sezulu sethu?
Ekhoneni lepaki, onqenqemeni lwenkundla yezindiza, noma phakathi nenkundla enkulukazi, kungenzeka uke wayibona—ibhokisi elimhlophe qwa elifana nendlu encane, limi buthule esigxotsheni. Ibonakala ilula, ngisho neyakudala, kodwa ngaphakathi, igada isisekelo sayo yonke isayensi yezezulu: idatha enembile, eqhathaniswayo yezemvelo.
Igama layo "indawo yokukhosela yezinsimbi," kodwa yaziwa kakhulu ngokuthi iStevenson Screen. Umgomo wayo ukuba “umahluleli ongakhethi,” othatha izinga lokushisa lemvelo futhi urekhode ukushaya komoya, ngaphandle kokuchema.
I. Kungani “Ibhokisi”? Izitha Ezintathu Zedatha Enembile
Zibone ngeso lengqondo ubeka ithermometer elangeni. Ukufundwa kwayo bekuzonyuka kakhulu ngenxa yemisebe yelanga, yehluleke ukukhombisa izinga lokushisa langempela lomoya. Ukulifaka ebhokisini elivalekile bekuzolishintsha libe “kuhhavini” ngenxa yokuntuleka komoya.
Ukwakhiwa kwesikrini sikaStevenson kuyisixazululo esihlakaniphile sokulwa ngesikhathi esisodwa nezitha ezintathu eziyinhloko zokunemba kwedatha:
- I-Solar Radiation: Indawo emhlophe ecwebezelayo yenza ukukhanya kwelanga kube ngcono, kuvimbele ibhokisi ekumunceni ukushisa nokufudumala.
- Imvula Nomoya Oqinile: Uphahla olutshekile kanye nesakhiwo esivundlile kuvikela ngempumelelo imvula, iqhwa, noma isichotho ukuthi zingangeni ngokuqondile, kuyilapho sinciphisa umthelela womoya onamandla kumathuluzi.
- Ukushiswa Kokushisa Okusuka Phansi: Ukufakwa endaweni yokuphakama okujwayelekile okungamamitha angu-1.5 kuyibeka kude nokushisa okuvela phansi.
II. Kungani “amaLouvers”? Ubuciko Nesayensi Yokuphefumula
Ingxenye ehlakaniphe kakhulu ye-Stevenson Screen yi-louvers yayo. Lawa mabhodi atshekile awahlobisi; bakha isimiso somzimba esinembile:
- I-Ventilation Yamahhala: Idizayini evundlile ivumela umoya ukuthi ugeleze ngokukhululeka, iqinisekisa ukuthi amathuluzi angaphakathi alinganisa umoya onyakazayo, omelela umoya wendawo, hhayi omile, “ovaleleke” umoya wendawo.
- I-Light Barrier: I-engeli ethile yama-louver iqinisekisa ukuthi kungakhathaliseki ukuthi ilanga likuphi, ukukhanya kwelanga okuqondile akukwazi ukufinyelela kumathuluzi angaphakathi, okudala indawo ehlala njalo yomthunzi.
Lo mklamo uphumelele kangangokuthi umgomo wawo oyinhloko awushintshile kusukela wasungulwa ngekhulu le-19. Iqinisekisa ukuthi idatha evela eziteshini zesimo sezulu emhlabeni wonke iqoqwa ngaphansi kwezinga elifanayo, okuvumela idatha evela e-Beijing ukuthi iqhathaniswe ngokunengqondo nedatha evela eNew York. Lokhu kunikeza uchungechunge lwedatha lwesikhathi eside, olungaguquki, noluyigugu lokufunda ukushintsha kwesimo sezulu emhlabeni jikelele.
III. I-Modern Evolution: Ukusuka Kwezinga Lokushisa Kuya Ekugadweni Kwegesi
Isikrini sendabuko sikaStevenson sasivikela ngokuyinhloko ama-thermometer nama-hygrometer. Namuhla, umgomo wayo wandile. I-"Thermohydrometer and Gas Shelter" yesimanje ingase ibe:
- Izinzwa ze-CO₂: Ukuqapha amazinga angemuva e-carbon dioxide emkhathini, okubalulekile ocwaningweni lwe-greenhouse effect.
- Ezinye Iziphequluli Zegesi: Ukuze kuqashwe i-ozone, i-sulphur dioxide, namanye amagesi athinta ezolimo, i-ecology, nempilo yomphakathi.
Ihlala ingumnakekeli ofanayo ongakhethi, ogcina izimfihlo eziningi.
Isiphetho
Ezweni eligcwele izinzwa ezihlakaniphile nama-buzzwords e-IoT, i-Stevenson Screen, enobuhlakani baso bomzimba bakudala, isikhumbuza ukuthi ukunemba kwedatha kuqala ezingeni elibaluleke kakhulu. Kuyibhuloho elixhuma okwedlule nekusasa, isisekelo esithulile sesayensi yesimo sezulu. Ngokuzayo uma ubona eyodwa, uzokwazi ukuthi akulona nje ibhokisi elimhlophe—kuyithuluzi elinembayo “elizwa” ukushaya kwemvelo esintwini, “umahluleli ongakhethi” waphakade wedatha, omile eqinile phakathi komoya nemvula.
Isethi ephelele yamaseva nesoftware engenantambo, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
