Txoj haujlwm no yug tom qab ServetI lub zais pa thaum lub caij ntuj sov xyoo 2017 nrog lub tswv yim xa cov duab hauv lub sijhawm tiag tiag los ntawm Stratosphere rau lub Ntiaj Teb. Cov duab uas peb tau muab khaws cia rau hauv rpi lub cim xeeb thiab tom qab ntawd, lawv tau xa ua tsaug kom hloov pauv mus ua lub teeb liab. Cov duab yuav tsum raug xa txhua lub sijhawm 'x' mus rau chaw tswj hwm. Nws kuj tau hais qhia tias cov duab no yuav muab cov ntaub ntawv xws li ntsuas kub lossis qhov siab, nrog rau kev txheeb xyuas kom txhua tus neeg uas yuav tau txais daim duab, nws tuaj yeem paub tias nws yog dab tsi.
Hauv kev xaus, Rpi-z siv cov duab thiab sau cov txiaj ntsig ntawm lub ntsuas (ntsuas kub thiab av noo). Cov txiaj ntsig no tau khaws cia hauv CSV cov ntaub ntawv thiab tom qab, peb tuaj yeem siv nws los ua qee cov duab. Cov tshuaj ntsiav xa cov duab SSTV siv daim ntawv sib piv los ntawm xov tooj cua. Nws yog tib qho kev siv los ntawm ISS (Chaw Thoob Ntiaj Teb Chaw Thoob Ntiaj Teb), tab sis peb cov duab muaj kev daws teeb meem tsawg dua. Ua tsaug rau nws, nws siv sijhawm tsawg dua los xa cov duab.

Kauj ruam 2: Pi-Zero
Rpi Zero Peb xav tau nruab Raspbian nrog cov duab ib puag ncig, nkag mus rau cov ntawv qhia zaub mov raspi-teeb tsa peb yuav ua kom lub koob yees duab cuam tshuam, I2C thiab Serial. Tau kawg lub graphical interface tsis yog yuav tsum tau tab sis kuv siv nws los ntsuas qhov system. Ua tsaug rau WS4E, vim nws piav qhia kev daws teeb meem rau SSTV hla RPID rub tawm SSTV nplaub tshev ntawm peb lub chaw cia khoom thiab rub nws mus rau koj "/home/pi" phau ntawv teev npe cov cai tseem ceeb hu ua sstv.sh, thaum yuav pib txoj cai, nws pab kev sib txuas lus nrog xov tooj cua module thiab bmp180 sensor, kuj tseem yuav thaij duab thiab hloov nws mus rau hauv lub suab kom xa nws los ntawm xov tooj cua rau hauv lub suab.
Koj tuaj yeem sim cov kab ke siv lub suab ncaj ncaj txiv neej rau txiv neej 3.5 hli lossis siv cov xov tooj cua thiab lwm yam khoom siv kom tau txais cov ntaub ntawv zoo li SDR lossis ib tus neeg taug kev-tham nrog Android Robot36 daim ntawv thov.
Kauj ruam 3: Devices
RTC thiab BMP180 chav nyob tuaj yeem sib dhos ua ke ntawm lub pcb, ua tsaug rau nws lawv tuaj yeem sib qhia tib yam khoom siv thiab kev sib txuas lus sib tham. Txhawm rau teeb tsa cov qauv no tuaj yeem ua raws cov lus qhia ntawm nplooj ntawv hauv qab no, uas tau pab kuv.
Kauj ruam 4: Lub Koob Yees Duab Chaw
Hauv peb qhov haujlwm peb tuaj yeem siv lub koob yees duab tab sis peb nyiam siv raspi-cam v2 los ntawm qhov hnyav, qhov zoo thiab qhov loj me. Hauv peb tsab ntawv peb siv Fswebcam daim ntawv thov los thaij duab thiab muab cov ntaub ntawv hais txog lub npe, hnub tim thiab txiaj ntsig ntsuas los ntawm OSD (ntawm cov ntaub ntawv tshuaj ntsuam). Txog qhov raug kuaj pom lub koob yees duab los ntawm peb cov software peb xav tau saib cov lus qhia no.
Kauj Ruam 5: Suab Tso Tawm
Rpi-xoom tsis tau hais ncaj qha rau lub suab tso tawm, qhov no yuav tsum tau ntxiv daim npav me me los ntawm USB lossis tsim ib qho yooj yim Circuit Court uas tsim lub suab los ntawm ob lub PWM GPIO chaw nres nkoj. Peb tau sim thawj qhov kev daws teeb meem nrog USB daim npav suab tab sis qhov no tau rov pib dua txhua lub sijhawm uas lub xov tooj cua tau muab tso rau TX (Yam Tsis Zoo). Thaum kawg, peb siv lub suab tso tawm los ntawm PWM tus pin. Nrog ob peb yam, koj tuaj yeem tsim lub lim kom tau lub suab zoo dua.
Peb tau sib sau ua tiav qhov Circuit Court nrog ob txoj hauv kev, L thiab R suab tab sis koj tsuas xav tau ib qho. Ntxiv mus, thiab raws li koj tuaj yeem pom hauv cov duab thiab cov phiaj xwm peb tau ntxiv 600 ohm suab hloov pauv zoo li rwb thaiv tsev galvanic. Tus hloov pauv yog nyob ntawm yeem tab sis peb nyiam siv nws txhawm rau zam kev cuam tshuam.
Kauj Ruam 6: Xov Tooj Cua VHF
Tus qauv siv yog DRA818V. Kev sib txuas lus nrog tus qauv yog los ntawm qhov chaw nres nkoj txuas yog li peb yuav tsum ua kom nws nyob hauv GPIO pins. Hauv RPI cov ntawv kawg muaj teeb meem hauv kev ua vim RPI muaj Bluetooth module uas siv tib tus pin. Thaum kawg, Kuv pom qhov kev daws teeb meem los ua qhov no hauv qhov txuas.
Ua tsaug rau uart peb tuaj yeem tsim kev sib txuas lus nrog tus qauv los muab xov tooj cua tshaj tawm, txais tos (nco ntsoov tias yog tus xa xov) nrog rau lwm yam kev ua haujlwm tshwj xeeb. Hauv peb qhov xwm txheej, peb tsuas yog siv tus qauv ua tus xa tawm thiab ib txwm nyob hauv tib zaus. Ua tsaug rau tus lej GPIO, nws yuav qhib rau PTT (Txuas mus tham) xov tooj cua qauv thaum peb xav xa daim duab.
Ib qho tseem ceeb tshaj plaws ntawm cov cuab yeej no yog qhov tsis zam lub zog 5v thiab peb hais qhov no los ntawm … "kev paub". Yog li peb tuaj yeem pom hauv cov phiaj xwm uas muaj cov diode raug 1N4007 los txo qhov hluav taws xob mus rau 4.3V. Peb kuj tseem siv me me transistor los ua haujlwm PTT. Lub zog hluav taws xob tuaj yeem teeb tsa ntawm 1w lossis 500mw. Koj tuaj yeem nrhiav cov ntaub ntawv ntau ntxiv txog tus qauv no ntawm cov ntawv teev npe.
Kauj Ruam 7: Kav hlau txais xov
Nws yog ib qho tseem ceeb ntawm cov tshuaj ntsiav. Kav hlau txais xov xa xov xov tooj cua mus rau lub hauv paus chaw nres tsheb. Hauv lwm lub tsiav tshuaj peb kuaj nrog enna lambda antenna. Txawm li cas los xij, txhawm rau kom ntseeg tau tias muaj kev pov hwm zoo, peb tsim lub kav hlau txais xov tshiab hu ua Turnstile (hla dipole). Txhawm rau tsim lub kav hlau txais xov no, koj xav tau ib kab ntawm 75 ohm thiab 2 meters ntawm txhuas raj ntawm 6mm txoj kab uas hla. Koj tuaj yeem pom cov lus suav thiab tsim 3D ntawm daim uas tuav lub dipole hauv qab ntawm cov tshuaj ntsiav. Peb tau sim qhov kev tiv thaiv ntawm tus kav hlau txais xov ua ntej tshaj tawm thiab thaum kawg, nws xa cov duab dhau 30 km ua tiav.
-Txhua yam los xam qhov ntev ntawm tus kav hlau txais xov (nrog peb cov ntaub ntawv)
Frecuency ntawm SSTV ntawm Spain: 145.500 MhzVelocity piv ntawm txhuas: 95%Kev nrawm tshaj ntawm 75 ohm cable: 78%
Kauj Ruam 8: Cov Khoom Siv Hluav Taws Xob
Koj tsis tuaj yeem xa cov roj teeb alkaline mus rau hauv stratosphere nws tau qis dua -40'C thiab lawv tsuas yog tso tseg kev ua haujlwm.
Yog tias koj siv dc-dc hloov pauv qhov qis tshaj tawm kev tswj hwm tom qab ntawd koj tuaj yeem yws ntau lub davhlau-sijhawm los ntawm koj lub hwj chim-pob
Peb siv watimetter los ntsuas kev siv hluav taws xob thiab yog li xam pes tsawg teev nws tuaj yeem ua haujlwm. Peb tau yuav tus qauv thiab teeb tsa hauv lub thawv me me, peb poob rau hauv kev hlub nrog lub cuab yeej no sai.
Peb siv 6 pob ntawm AA roj teeb lithium thiab cov kauj ruam no.
Kauj Ruam 9: Tsim Tshuaj Tshuaj
Peb siv "ua npuas dej" los tsim lub cev hnyav thiab tiv thaiv kab mob. Peb ua nws nrog CNC ntawm Lab´s Cesar. Nrog lub tshuab txiav thiab kev saib xyuas, peb tau qhia txhua yam hauv nws. Peb qhwv cov tshuaj ntsiav grey nrog daim pam cua sov (Zoo li lub hnub qub tiag;))
Kauj ruam 10: Hnub Pib
Peb tau tshaj tawm lub zais pa ntawm 2018-25-02 hauv Agon, ib lub nroog ze Zaragoza, lub dav hlau pib thaum 9:30 thiab lub sijhawm ya davhlau yog 4 teev, nrog qhov siab tshaj ntawm 31, 400 meters thiab qhov kub sab nraud yam tsawg kawg nkaus ntawm - 48º Celsius. Nyob rau hauv tag nrho lub zais pa tau mus txog 200km. Peb muaj peev xwm txuas ntxiv nws txoj kev taug mus ua tsaug rau lwm lub tshuaj ntsiav Aprs thiab kev pabcuam ntawm www.aprs.fi
Txoj kev mus los tau suav nrog ua tsaug rau kev pabcuam www.predict.habhub.org nrog kev ua tiav zoo, raws li tuaj yeem pom hauv daim duab qhia chaw nrog kab liab thiab daj.
Qhov siab tshaj plaws: 31, 400 meters Qhov siab tshaj sau cia qhovntsej thiaj tsis mob: 210 kph Sau npe lub davhlau ya nyob twg qhov siab ceev: 7 m / s Sau npe sab nraud yam tsawg kawg nkaus kub: -48ºC txog 14, 000 meters siab
Peb tau ua SSTV tshuaj ntsiav tab sis txoj haujlwm no tsis tuaj yeem ua tiav yam tsis muaj kev pab los ntawm lwm tus koom tes: Nacho, Kike, Juampe, Alejandro, Fran thiab ntau tus neeg tuaj yeem pab dawb.
Kauj Ruam 11: Qhov Ua Tau Zoo Tshaj
Ua tsaug rau Enrique peb muaj cov vis dis aus luv luv ntawm kev ya dav hlau qhov twg koj tuaj yeem pom tag nrho cov txheej txheem pib. Tsis muaj kev poob siab qhov khoom plig zoo tshaj tom qab ua haujlwm hnyav
