Āpōpō ka tukuna e mātou tā mātou tūmau ki te paparangi. I te wā e rere ana, ka whakaratohia e te poihau te urunga ipurangi, ka hopu me te tuku raraunga ataata me te telemetry ki te Ao. Kua maha ā mātou tuhinga e whakapuaki ana i ngā taipitopito hangarau o tā mātou kaupapa "Whare Raraunga Mokowā" (i mua ko ""). I oati mātou—ka pupuri mātou i tēnā! Kei raro i te tapahi he ringa iti o ngā taputapu me ngā waehere.
Tūmau tukutuku
Ahakoa i roto i te kaupapa "Server in the Clouds" o mua, i te wā i piki ai mātou i roto i tētahi poihau wera tino nui me tētahi kapa tokorua, he mea koretake te tango i tētahi tūmau tino nui me tētahi kete pākahiko. Inaianei kei te kōrero mātou mō tētahi poihau iti e piki ana i te 30 km, kaua ki te 1 km. Nō reira, i whiriwhiria e mātou te Raspberry Pi kotahi hei tūmau tukutuku. Ka whakaputahia e tēnei rorohiko iti he whārangi HTML, ā, ka whakaatuhia ki tētahi whakaaturanga motuhake.
Ngā whakawhitiwhiti kōrero amiorangi
Haunga te Raspberry Pi, ka uru atu ngā modem mai i ngā whatunga whakawhitiwhiti amiorangi Iridium me Globalstar. E mahara ana pea koutou, i whakaaro mātou ki te tāpiri i tētahi modem mai i te whatunga Gonets ā-rohe ki ā rātou rarangi, engari kāore i a mātou te wā ki te whiwhi i te wā tika, nō reira ka tukuna atu e mātou i te rerenga e whai ake nei. Ka whiwhi te tūmau tukutuku i ō karere mā roto i ngā modem amiorangi, ka taea te tuku ki Ka tukuna ēnei karere ki te Raspberry Pi, ka whakarārangihia e rātou, ka whakaaturia ki tētahi whārangi HTML.
He mea nui: Ko te roanga o ngā karere kuputuhi i te reo Rūhia he 58 ngā pūāhua (tae atu ki ngā mokowā). Mena he roa ake te karere, ka tapahia i te wā e tukuna ana. Ka tangohia hoki ngā pūāhua motuhake katoa i te tuhinga, pēnei i: /+$%&;''""<>n me ērā atu mea pērā.
Nā te mea kotahi anake te tauranga UART o te Raspberry Pi, ka honoa e mātou ngā pouwhanga amiorangi mā te pokapū takawaenga, ka kohia ngā raraunga mai i ngā pouwhanga ka tukuna atu ki te Raspberry Pi.
Pouwhanga reo irirangi
Ehara i te mea ka whakaaturia noa e te tūmau tukutuku ngā karere katoa i riro mai i a koe i runga i te mata, engari ka tukuna atu hoki ki te Ao mā te pouwhanga reo irirangi LoRa. Koinei te huarahi e hiahia ana mātou ki te whakamātautau i te whakaaro o te tohatoha ipurangi mai i te paparangi (he whakanui i te kaupapa Google Loon). Ko te tikanga, ehara tā mātou poihau paparangi i te mea he pūrua whakawhitiwhiti kōrero tino matatau, engari ahakoa he rawaka ōna āheinga mō te tuku raraunga pumau me te kore e ngaro nui ngā raraunga, ka tino taea e ngā pūnaha motuhake te whakahaere i te tohatoha ipurangi mai i te wāhi-mua.
Telemetry
Kei te whakamahere hoki mātou ki te whakaatu i ngā raraunga telemetry ki te whārangi HTML kotahi. Ka whiwhi te Raspberry Pi i tēnei mai i tētahi atu kaiwhakahaere rere.
Ka tirotirohia e ia ngā momo pūoko, ka taea te whakanoho ki roto, ki waho hoki i te pouaka taputapu, ka kohia ngā raraunga, ka whakaritea, ka tukuna ki te whakatakotoranga watea ki te hunga e tono ana. I roto i tā mātou take, ka tono ia i tētahi Raspberry Pi. Ka tuhia e mātou te pēhanga, te teitei, ngā taunga GPS, te tere poutū me te whakapae, me te pāmahana.
Ka tukuna ngā raraunga mai i te kaiwhakahaere rere i roto i ngā aho roa, ā, ka tukatukahia ēnei mā te whakamahi i tēnei waehere:
$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
':' => '=',
';' => '&'
]), $result);
print_r($result);ka hurihia hei rarangi i roto i tētahi āhua e watea ana mō te whakaatu:

)Ka tukuna atu hoki e mātou ngā raraunga telemetry ki te Ao me āu karere. Mō tēnei kaupapa, ka whakatūria e mātou he teihana whiwhi ki te wāhi whakarewatanga.
Whakaaturanga me te kāmera
Hei whakarite kei te whiwhi te tūmau i ō karere mā te amiorangi, ā, kei te ao tūroa tonu, kaua e noho noa i roto i tō mātou tari, i whakatau mātou ki te whakaatu i ngā karere telemetry katoa ki runga i tētahi whakaaturanga i hopukina e tētahi GoPro. He iti noa te wā i pau i a mātou ki te whakarite i te kaupapa (ā, āhea rā te wā e nui ai?!), nō reira i whakarērea e mātou te raruraru o AliExpress me te rino whakapiri, engari i whiriwhiria he taputapu kua oti te hanga. He nui atu i te rawaka mō ā mātou hiahia. Ka honoa e mātou te whakaaturanga ki te Raspberry Pi mā te HDMI.
Kei te whakaaro hoki mātou ki te whakapāho ataata mai i te GoPro mā tētahi hongere reo irirangi motuhake, engari kāore anō kia mōhiotia me pēhea te mahi—ka taea e te iti o te kapua te whakaiti i te whānuitanga o te whakawhitiwhiti kōrero. Ahakoa pēhea, i muri i te kimi i te poihau kua tau, ka tukuna atu e mātou te ataata mai i te kāmera, ā, ka taea e koe te kite māu ake he aha ngā karere i riro mai i tā mātou "pokapū raraunga i mua i te mokowā" me te teitei i tae atu ai—ka whakaaturia te telemetry ki te whārangi HTML kotahi, ā, ka kitea tētahi wāhanga o te pae tawhiti.
Питание
Ka whakakahangia tēnei ataahua katoa e te pākahiko lithium 3S4B—e toru e raupapa ana, e whā e whakarara ana. Ko te kaha katoa e tata ana ki te 14 Ah i te 12 V. E whakaaro ana mātou he rawaka tēnei, engari i muri i te huihuinga whakamutunga, ka inehia e mātou te whakapaunga tuturu, ā, ka tāpirihia atu ētahi atu pākahiko mēnā e tika ana.
Tāpirihia ki ēnei katoa ngā tohu GPS, ka whakamahia e tātou hei kimi i te poihau kua tau. Ā, ka noho te whare ārai hei "kāinga" mō te tūmau me ētahi atu taputapu.
Ka tiakina ngā taputapu ngāwari mai i ngā rerekētanga o te pāmahana me te pēhanga. Ka whakaitihia hoki te horopeta irahiko, ahakoa kāore he pānga o tēnei ki tā mātou kaupapa; kāore te tūmau e rere roa i te paparangi, ā, kāore te irahiko papamuri i reira e teitei pērā i te ISS.
Haunga te tuku karere ki , ka taea e koe te whai wāhi atu ki tētahi whakataetae me te matapae i te wāhi taunga o te waka rererangi. Ko te taonga nui he haerenga ki Baikonur mō te whakarewatanga o te waka mokowhiti Soyuz-MS-13.
