ʻApōpō e hoʻouna mākou i kā mākou kikowaena i ka stratosphere. I ka holo ʻana, e puʻunaue ka baluna stratospheric i ka Pūnaewele, pana a hoʻouna i ka ʻikepili wikiō a me ka telemetry i ka honua. Ua kākau mākou i mau manawa e kamaʻilio mākou e pili ana i ka ʻaoʻao ʻenehana o kā mākou papahana "Space Data Center" (i pane mua ʻia i ka inoa ""). Ua hoʻohiki mākou - hāʻawi mākou! Ma lalo o ka ʻokiʻoki aia kahi lima o nā ʻāpana ʻāpana a me nā code.
kikowaena pūnaewele
ʻOiai i ka papahana "Server in the Clouds" ma mua, i ka wā i piʻi ai mākou i kahi baluna piha me kahi ohua o ʻelua mau kānaka, lawe pū me mākou i kahi kikowaena piha piha me kahi hui pākahi, e ʻōlelo mākou, ʻaʻole noʻonoʻo. A i kēia manawa ke kamaʻilio nei mākou e pili ana i kahi balloon stratospheric liʻiliʻi, pono e piʻi i 30 km, ʻaʻole 1. No laila, ua koho mākou i ka Raspberry Pi like me kahi kikowaena pūnaewele. Na kēia microcomputer e hana i kahi palapala HTML a hōʻike iā ia ma kahi hōʻike ʻokoʻa.
Hoʻohui Satellite
Ma waho aʻe o Raspberry, e lele ana nā modem mai ka Iridium a me Globalstar satellite communication network ma luna o ka moku. E like me kāu e hoʻomanaʻo ai, ua hoʻolālā mākou e hoʻohui i kahi modem no ka pūnaewele Gonets kūloko i kā lākou hui, akā ʻaʻole i loaʻa iā mākou ka manawa e loaʻa mua ai, no laila e hoʻouna mākou iā ia i ka lele aʻe. Ma o nā modem satellite, e loaʻa i ka pūnaewele pūnaewele kāu mau memo, hiki ke hoʻouna ʻia i . E hoʻouna ʻia kēia mau memo i ka Raspberry Pi, e hoʻonohonoho iā lākou a hōʻike iā lākou ma kahi ʻaoʻao HTML.
Manaʻo nui: ʻo ka palena o ka lōʻihi o kahi memo ma ka ʻōlelo Lūkini he 58 mau huaʻōlelo (me nā hakahaka). Inā ʻoi aku ka lōʻihi o ka memo, e ʻoki ʻia ia i ka wā o ka hoʻouna ʻana. Eia kekahi, e ʻoki ʻia nā kiʻi kūikawā a pau mai ka kikokikona, no ka laʻana, /+$%&;''""<>n a me nā mea like.
No ka mea, hoʻokahi wale nō awa UART o ka Raspberry Pi, e hoʻopili mākou i nā modem satellite ma o kahi hub waena, e hōʻiliʻili i ka ʻikepili mai nā modem a hoʻouna iā ia i ka Raspberry Pi.
Modem lekiō
ʻAʻole e hōʻike wale ke kikowaena pūnaewele i nā memo a pau i loaʻa mai iā ʻoe ma ka hōʻike, akā e hoʻouna pū iā ia i ka Honua ma o ka modem radio LoRa. No laila makemake mākou e hoʻāʻo i ka manaʻo o ka hāʻawi ʻana i ka Pūnaewele mai ka stratosphere (he hoʻomaikaʻi i ka papahana Google Loon). ʻOiaʻiʻo, ʻaʻole ʻo kā mākou baluna stratospheric kahi kamaʻilio kamaʻilio piha, akā inā lawa kona hiki no ka hoʻouna ʻana i ka ʻikepili paʻa, me ka ʻole o ka nui o ka ʻike, a laila e hoʻokō pono nā ʻōnaehana kūikawā i ka hāʻawi ʻana i ka Pūnaewele mai mua o ka hakahaka.
Telemetry
Eia hou, hoʻolālā mākou e hōʻike i ka ʻikepili telemetry ma ka ʻaoʻao HTML like. Na ka Raspberry Pi e lawe iā lākou mai kahi mea hoʻokele lele kaʻawale.
Nīnau ʻo ia i nā mea ʻike like ʻole i hiki ke waiho ʻia ma loko a ma waho o ka pahu hermetic hardware, hōʻiliʻili i ka ʻike i loko o kahi puʻu, hoʻopili a hāʻawi ʻia i kahi ʻano kūpono i ka poʻe e noi. I kā mākou hihia, e noi ia iā Raspberry Pi. E hoʻopaʻa mākou i ke kaomi, ke kiʻekiʻe, nā hoʻonohonoho GPS, ka wikiwiki a me ka wikiwiki a me ka mahana.
Hoʻouna ʻia ka ʻikepili mai ka mea hoʻokele lele ma nā laina lōʻihi, ʻo ia hoʻi, me ka hoʻohana ʻana i kēia code:
$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
':' => '=',
';' => '&'
]), $result);
print_r($result);e hoʻololi i kahi ʻano ma kahi ʻano kūpono no ka hōʻike ʻana:
Array

)E hoʻolaha pū mākou i ka ʻikepili telemetry i ka Honua me kāu mau memo. No ka hana ʻana i kēia, e kau mākou i kahi kikowaena hoʻokipa ma ka pūnaewele hoʻomaka.
Hōʻike a me ka pahupaʻikiʻi
No laila hiki iā ʻoe ke hōʻoia i ka loaʻa ʻana o kāu mau memo ma o ke kamaʻilio ukali, a ua lele maoli ʻo ia i ka stratosphere a ʻaʻole kū i loko o kā mākou keʻena, ua hoʻoholo mākou e hōʻike i nā memo āpau me ka telemetry ma kahi hōʻike e hopu ʻia e he GoPro. He liʻiliʻi ka manawa e hoʻomākaukau ai i ka papahana (pehea e hiki ai i ka nui o ia mea?!), no laila ʻaʻole mākou i pilikia me Aliexpress a me kahi hao hao, akā ua lawe i kahi mea i mākaukau. ʻOi aku ia ma mua o ko mākou pono. E hoʻopili mākou i ka hōʻike i ka Raspberry ma o HDMI.
Hoʻolālā pū mākou e hoʻolaha wikiō mai GoPro ma o kahi kaila lekiō ʻokoʻa, akā ʻaʻole ʻike ʻia pehea e hana ai - malia paha e hoʻemi nui nā ao haʻahaʻa i ka laulā kamaʻilio. Akā i kekahi hihia, ma hope o ka loaʻa ʻana o ka balloon stratospheric pae ʻāina, e kau mākou i kahi wikiō mai ke kāmela a ʻike ʻoe iā ʻoe iho i nā leka i loaʻa i kā mākou "pre-space data center" a me ke kiʻekiʻe i piʻi ai - e hōʻike ʻia ka telemetry. ma ka ʻaoʻao HTML hoʻokahi, Eia kekahi, e ʻike ʻia kahi ʻāpana o ka lewa.
Ka lako
ʻO nā mea nani a pau i hōʻike ʻia ma luna nei e hoʻoikaika ʻia e kahi hui o nā pākahi lithium i hōʻuluʻulu ʻia e like me ke kaapuni 3S4B - ʻekolu i ka pūʻulu, ʻehā i ka like. ʻO ka nui o ka mana ma kahi o 14 Ah ma ka volta o 12 V. E like me kā mākou mau manaʻo, pono e lawa kēia, akā ma hope o ka hui hope, ʻoiaʻiʻo, e ana mākou i ka hoʻohana maoli ʻana, a inā pono, e hoʻohui hou i nā pā.
E hoʻohui i kēia mau kukui GPS, a mākou e hoʻohana ai no ka ʻimi ʻana i ka baluna stratospheric i pae. A ʻo ka pahu hermetic ka "hale" no ke kikowaena a me nā mea hana ʻē aʻe.
Mālama ia i nā mea hana maʻalahi mai ka hoʻololi ʻana i ka mahana a me ke kaomi. I ka manawa like, e hoʻemi ana ia i ka nui o ka radiation, ʻoiai ʻaʻole ia e pāʻani i kā mākou papahana, e lele ke kikowaena i ka stratosphere no ka manawa pōkole, a ʻaʻole kiʻekiʻe ke kiʻekiʻe ma laila e like me ka ISS.
Ma waho aʻe o ka hoʻouna ʻana i nā leka i , hiki iā ʻoe ke komo i ka hoʻokūkū a koho i kahi e pae ai ka ʻimi. ʻO ka makana nui he huakaʻi i Baikonur no ka hoʻokuʻu ʻia ʻana o ka Soyuz-MS-13 manned spacecraft.
