E nā hoaaloha, ʻo ia ka manawa e hōʻuluʻulu i nā hopena o kā mākou papahana hoʻokūkū "Server in the Clouds". Inā ʻaʻole ʻike kekahi, ua hoʻomaka mākou i kahi papahana geek leʻaleʻa: hana mākou i kahi kikowaena liʻiliʻi ma Raspberry Pi 3, hoʻopili i kahi tracker GPS a me nā mea ʻike iā ia, hoʻouka i kēia mau mea a pau ma luna o kahi baluna ea wela a hāʻawi iā ia i nā mana o ke ʻano. . ʻO kahi e pae ai ka pōleʻa, ʻike wale ʻia e nā akua makani a me nā mea mālama o ka aeronautics, no laila ua kono mākou i nā mea a pau e kau i nā kiko ma ka palapala ʻāina - nona nā kiko kokoke loa i ka pae ʻāina maoli e loaʻa nā makana "ʻono".
No laila, ua lele mua kā mākou kikowaena i nā ao, a ʻo ka manawa kēia e hōʻuluʻulu i nā hopena o kā mākou hoʻokūkū.
Nā loulou i nā puke mua e pili ana i ka hoʻokūkū
- (ʻo ka makana no ka wahi mua o kā mākou hoʻokūkū ʻo ke komo ʻana i ka regatta holo moku, e mālama ʻia ana mai Nowemapa 3 a hiki i ka 10 ma ka Saronic Gulf (Greece) me ka hui RUVDS a me Habr.
- Pehea mākou i hana ai "»ka papahana - no ka poʻe pā i ka porn geek, me nā kikoʻī a me ka loiloi code.
- me ka wehewehe piha.
- , kahi i hiki ai ke nānā i ka neʻe ʻana o ka pōpō a me ka telemetry i ka manawa maoli.
- mai kahi i hooleleia ai ka poepoe.
A ʻo ka ʻike, ke keiki o nā hewa paʻakikī
Ke hoʻomanaʻo nei ʻoe, ua hoʻolālā mākou e hoʻolaha i ka ʻikepili mai ke kikowaena ma o kahi modem GSM. ʻO kēia ke ala nui no ka hoʻouna ʻana i ka ʻike. Me he mea lā ua hāʻawi mākou i nā mea kupanaha me ka uhi ʻana o ka pūnaewele kelepona ma o ka hoʻokomo ʻana i loko o ka modem ʻelua kāleka SIM mai nā mea hoʻohana me ka uhi maikaʻi loa ma ka ʻāina Dmitrovsky. Eia kekahi, ua loaʻa i ka modem kahi antenna omnidirectional maikaʻi. Akā, e like me kā lākou e ʻōlelo nei, manaʻo ke kanaka, a hoʻopau nā opsos. I ka piʻi ʻana o ka pōleʻa ma luna o 500 mika (ke kiʻekiʻe o ka hale kiaʻi TV Ostankino), ua nalowale loa nā kamaʻilio kelepona.
I ka nānā ʻana, ʻike maopopo ʻia, akā ʻo ia ke ʻano o ka hindsight. ʻOiaʻiʻo, ua hoʻolālā ʻia nā antenna kelepona no ka uhi ʻana ma ka honua, ʻaʻole i ka lewa. ʻO kā lākou mau hiʻohiʻona radiation "kuʻi" ma ka hoʻomaha a ʻaʻole "alohi" i nā ao. No laila, ʻo ke kamaʻilio kelepona ma kahi kiʻekiʻe o ka hapalua kilomita a ma luna aʻe he hōʻike wale nō ia o ka lobe o kekahi antenna. No laila, no ka hapalua o ke ala, ʻaʻohe kamaʻilio me ka baluna ma o ke ala kelepona. A i ka wā o ka iho ʻana, i ko mākou hele ʻana ma lalo o 500 mika, hoʻomaka hou nā kamaʻilio kelepona.
Pehea i loaʻa ai iā mākou ka telemetry mai ka baluna? Mahalo i ke ala hoʻoili ʻikepili redundant no kēia. Hoʻokomo mākou i kahi kit ma ka pōleʻa, e hana ana ma 433 MHz.
He liʻiliʻi kona throughput, akā no kā mākou kumu ua lawa. No ka hoʻoholo ʻana i kahi o ka pōleʻa me ka hoʻohana ʻana i ka GPS, ʻaʻohe pilikia me kēia; ua hana ka tracker me ka ʻole o nā hiccups.
A i ka wā o ka lele, ua ʻike ʻia ʻo ke kelepona USB e hoʻopili ana i ka module telemetry i ka Raspberry Pi 3 ua hewa. Ua hana ʻo ia ma ka honua, akā hōʻole ʻo ia e hele i ka lani. Makaʻu paha i ke kiʻekiʻe. Ua ʻike mākou i ka hewa o ke kaula ma hope o ka pae ʻana. ʻO ka mea pōmaikaʻi, ua hiki iā mākou ke hoʻokumu pololei i ka hoʻoili ʻikepili mai ka module telemetry ma o LoRa.
A e pili ana i ka maikaʻi
Ua minoʻaka ka laki i ka poʻe habrayuser @ (kahi mua), @ (kahi lua) a me @ (wahi ʻekolu)! ʻO ka mea laki loa e loaʻa i nā manaʻo he nui (manaʻolana ʻoluʻolu) mai, a e hōʻike koke mākou i nā smartphones maikaʻi i ka poʻe paʻa i ka lua a me ke kolu. A ʻoiaʻiʻo, e loaʻa iā mākou ʻekolu ka hoʻolimalima manuahi o kahi kikowaena virtual mai RUVDS ma ke ʻano he makana.
Hiki iā ʻoe ke ʻike i ke ʻano o ka hoʻomaka ʻana i kēia wikiō pōkole:
