Seva m'mitambo: kukonzekera kuyambitsa

В positi za regatta Tidanena kuti mu Ogasiti padzakhala mpikisano wokhala ndi mphotho kwa ma Habrazhitel onse. Nthawi yakwana yochotsa chophimba cha chinsinsi. Mwanjira ina tinapeza lingaliro lakuti mawu akuti "seva mumitambo" angatengedwe kwenikweni. Tiyeni tiyambitse seva yogwira ntchito mumlengalenga yomwe imatha kuyimitsidwa! Poyamba lingalirolo linkawoneka ngati lopenga, koma titatha kulipotoza uku ndi uku, kukambirana mwa njira iliyonse, potsirizira pake tinadza ndi njira yotumizira seva kwa mbalame. Kukhazikitsa kwanthawi yayitali kudzachitika kumapeto kwa Ogasiti, koma pakadali pano tikugwira ntchito pagawo la hardware la polojekitiyi. Tsatanetsatane pansi pa odulidwa.

1. Seva idzakhazikitsidwa pa Raspberry Pi 3

   Zingakhale zosangalatsa kukweza seva ya unit imodzi mumlengalenga, koma kulemera kwake + kulemera kwa UPS ... Zonsezi zingafune mphamvu yokweza kwambiri. Ndipo bwanji, ngati pamaziko a compact Raspberry Pi 3 mutha kuyika seva yabwino kwambiri, yokhala ndi mphamvu yamakompyuta nthawi mazana angapo kuposa makina omwe Tim Berners-Lee adasangalala nawo mu 1991.

2. Tiyeni tiyambitse seva mu baluni ya mpweya wotentha

   Tinali ndi malingaliro okweza seva pa kafukufuku wa helium, koma ndiye seva sichinali kulira kwa nthawi yayitali chibaluni chisanaphulike pamalo okwera mumlengalenga wosowa kwambiri ndipo mawonekedwe onsewo amagwa pansi. Ndinkafuna kuwonjezera "zenera" la airtime mpaka ola limodzi ndi theka. Ndiyeno anaganiza zogwiritsa ntchito baluni. Kutalika kwa ndege ndi maola awiri. Kuwonjezera apo, ngakhale kuti ndegeyo siikhoza kulamulirika kotheratu, pangakhale injiniya wathu m’basiketiyo amene, ngati zasokonekera, “akhoza “kuyatsa ndi kuzimitsa” pomwepo, pomwepo.

3. Tidzagwiritsa ntchito ma cellular communications ngati network yoyendera

   Ma antennas amakono a WiFi amatha "kuboola" mtunda wautali, koma pachifukwa ichi pangakhale kofunikira kuti apange njira yolumikizirana yomwe siili yotsika kwambiri pamagawo ake ngati siteshoni ya radar yankhondo. Ndipo chifukwa cha kulankhulana kwa maola 1,5-2, sikumveka kupanga dongosolo loterolo, chifukwa pamtunda wa baluni, mauthenga a m'manja ayenera kugwira ntchito mokhazikika.

Titapanga “zolemba” zimenezi, ntchitoyi sinaonekenso yosatheka, ndipo posakhalitsa tinayamba kugwira ntchito mbali zonse zitatu nthawi imodzi.

Choyamba, tinatembenukira kwa anyamata ochokera Nearspace.ru, amene adadya galuyo pamene akutulutsa zidutswa zazitsulo zamtundu uliwonse mumlengalenga (ndi kufufuza ndi kupulumutsa).

Kenako tidatulutsa Raspberry Pi 3, yomwe idagona patebulo la olamulira athu, ndikuyamba kuyiyika.

Cholumikizira kamera:

Ndipo tidayesa pa "Semyon" yathu:

Semyon ndi yabwino kwambiri monga chitsanzo ndi wothandizira - samapempha chakudya, samasokonezedwa ndi foni, nthawi zonse amakhala ndi maganizo abwino komanso akumwetulira kwakukulu kuchokera pachipewa chake chonse. Zoonadi, sitifunikira mlengalenga wotero wa ndege, koma zimapanga mpweya wabwino muofesi.

Ndondomeko ya polojekitiyi ndi iyi:

Powerbank imagwiritsidwa ntchito poyesa pansi; china chake chodalirika chimafunikira pakuyambitsa.

Mwina chida chosangalatsa kwambiri ndi bolodi lolandirira deta kuchokera ku masensa onse:

Anyamata ochokera Nearspace.ru Tinalimbana kwa nthawi yayitali ndi ma analogue osiyanasiyana, kenako tidapanga tokha pakompyuta, chifukwa kudalirika ndikofunikira kwambiri, tsogolo la polojekiti yonseyo zimadalira deta ya telemetry. Makompyuta omwe ali pa board ali ndi udindo wolandila zidziwitso kuchokera ku masensa onse olumikizidwa ndikuzitumiza ku Raspberry Pi.

Tidayiyambitsa, tidayikonza, ndipo patadutsa milungu ingapo ndikusewera ndi maseche, tidatha kupeza zambiri za telemetry ndi chithunzi cha Semyon kuchokera pa kamera yayikulu:

Deta ya Telemetry imafalitsidwa mumzere umodzi motere:

Khodi iyi imatembenuza chingwecho kukhala gulu ndikutulutsa deta patsamba:

$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
	
':' => '=',
	
';' => '&'
]), $result);
print_r($result);

Kufotokozera za data ina:

• N:2432; - nambala ya paketi ya data, ikuwonjezeka nthawi zonse
• T:40m39s; - nthawi kuyambira pomwe wowongolera ndege adayatsidwa
• MP.Stage: 0; - siteji ya ndege (0 - pansi kapena pansi pa 1 km, 1 - kukwera, 2 - kuyendayenda pamtunda, 3 - kutsika)
• MP.Alt:54; - kutalika kwa barometric mu mita kuchokera pamtunda wa nyanja - ziyenera kuwonetsedwa
• MP.VSpeed: 0.0; - Liwiro loyima pamamita pa sekondi imodzi yokhala ndi zosefera zapakatikati
• MP.AvgVSpeed: 0.0; - Liwiro loyima pamamita pa sekondi imodzi yokhala ndi zosefera
• Baro.Press:1006.49; - kuthamanga kwa barometer mu millibars
• Baro.Alt:54; - kutalika molingana ndi barometer
• Baro.Temp:36.99; - kutentha kwa barometer palokha
• GPS.Coord:N56d43m23s,E37d55m68s; - ma coordinates

• GPS.Alt:165; - GPS kutalika mu mita
• GPS.Dst:10; - mtunda kuchokera poyambira pamamita
• DS.Temp:[fc]=34.56; - sensor kutentha pa bolodi

Momwe zotsatira zake zimawonekera:

Zoyenera kuchita ngati kulumikizana kwa ma cell "kwagwa"? Pachifukwa ichi, tili ndi khadi yachiwiri; SIM makhadi awiri amalowetsedwa mu modem (kagawo kamodzi):

Ikhoza kusinthira ku tchanelo chotsalira ngati chachikulucho chasiya kuyankha mwadzidzidzi.

Kodi chingachitike ndi chiyani ngati maukonde onse a m'manja sakupezeka?

(Mwana wa nkhani "Yeralash" No. 45 Sizopanda pake kuti amawerenga "Lingaliro la Kuthekera")

Pankhaniyi, tidzakhala ndi GPS tracker yodziyimira yokha yomwe imatumiza chizindikiro cha malo ake. Chonde dziwani kuti sizimatero kudzera pa netiweki yam'manja, kupezeka kwake komwe mtunda wautali sikutsimikiziridwa ndi aliyense, koma kudzera pa satellite.

Inde, GPS tracker ndi yayikulupo kuposa yomwe idayikidwa pansi pakhungu la James Bond. Popeza mpikisano wathu umadalira kugwirizanitsa kwa seva yowuluka, gawo ili la deta lomwe limalandira kuchokera ku bolodi lidzakhala lofunika kwambiri. Koma tidzakambirana izi mu positi yotsatira. Ikubwera posachedwa, tsatirani blog yathu!

Timakhulupirira kuti bizinesi yonse yachita bwino kwambiri kotero kuti tidalengezanso mpikisano kwa iwo omwe mwadzidzidzi akufuna kuganiza komwe mpira utsikire. Tsatanetsatane wathu positi yatsopano.
