ndofungae vazhinji vedu tinorota sevana vekuve rimwe zuva mukana wekugona kuve nawo kana kubhururuka roketi rakagadzirwa kana ngarava diki yakagadzirirwa kubhururuka uye pamusoro pezvose kuve nemirairo inogona kutipa rusununguko rwekuitungamira pamadiro.
Nhasi, sekudaro, kurota uku kwakatozadziswa nevazhinji Zvakanaka, kune mamwe emhando dzekutengesa dzaunogona kutenga kana mune kesi yedrones, chimwe chinhu chakafanana nezvataizoda isu sevana.
Asi ngatitaurei chokwadi, vazhinji vedu vangadai vakada kugadzira chishandiso nemaoko edu uye pamusoro pesimba rese rekudzidza kuiunganidza uye mashandiro anoita chikamu chimwe nechimwe.
Uye zvakanaka nhasi ndauya kuzogovana ruzivo Ndakawana pamambure nezve chimwe chinhu chakafanana neicho ini chandinotsanangura uye ndizvo Cygnus-X1 chirongwa chinogadzira yakavhurika sosi bhodhi yejet injini yekukanda vector kutonga uye inoenderana pane-bhodhi masisitimu.
Vanofarira vanogona kushandisa ndiro kudzikamisa kubhururuka kwemaroketi akagadzirwa uye pamusoro pezvose uye chakanyanya kukosha chinhu nezve chirongwa ichi, ndechekuti budiriro dzeprojekti dzinogoverwa pasi pezenisi yeGPLv3.
Iyo yatingawana nayo yakawanda nhamba inowanika madhayagiramu, pcb dhizaini uye zvakatemwa zveiyo EasyEDA (Elektroniki Dhizaina Yekushandisa) simulator.
Chimwe chiitiko chinomira kunze kweprojekiti ndechekuti iyo bhodhi inoenderana zvizere neArduino IDE uye Platformio nharaunda dzekuvandudza.
Pamusoro pezvinhu zve software zviri kunyorwa muC ++ uye sehwaro, iyo SAMD51 microcontroller inoshandiswa, iyo inoshanda pa frequency ye120 MHz uye ine 1 MB yeyakavakirwa-mukati Flash memory.
Flash yekunze kana SD kadhi inogona kushandiswa kurekodha telemetry panguva yekubhururuka. Dhata uye mirairo zvinopfuudzwa kuburikidza neBluetooth Low Energy (BLE), iyo inobvumidza iwe kushandisa yakajairwa smartphone kutonga.
Nzira nhatu dzekutonga servo dzinopihwa: mbiri yekufamba kwemhino kana iyo vector ichichinja uye imwe yemamwe masisitimu, semuenzaniso, kumisikidza kutumirwa kweparachute. Kune zvakare maviri mapyrochannel ekuvesa uye anovhenekera plugs uye yemagetsi mota yekudzivirira chiteshi kuti ishandise coil nenzira yegyro.
2S kana 3S LiPo mabhatiri anogona kushandiswa sesimba sosi. Pakati pemaseru anoshandiswa pane yakasanganiswa accelerometer-gyro (IMU BOSCH BMI088) uye altimeter (MS560702). UART neI2C zvinowanika kuti ubatanidze mamwe maseru seGPS module.
Pakati pehunhu hunomira kunze kweprojekti, zvinotevera zvinotaurwa:
- Kubva pane iyo SAMD51 microcontroller inoshanda pa120 MHz ine 1 MB ye flash. (ATSAMD51J20A-MUT).
- Inodzora neBluetooth Low Energy (BLE), izvi zvinobvumira data kutumirwa uye kugamuchirwa pakati pe roketi ne smartphone.
- 3 Servo Channels (maviri mageji anoshandiswa kukanda vectoring uye imwe yezvimwe zvinhu senge yemuchina parachuti ejection system).
- 2 Pyro Channel inokwanisa kubatidza mota inodzima uye nichrome waya. Yakazara PWM inodzora kuitira kusiana kwazvino kutonga.
- 1 x DC mota chidhiraivhu chenguva idzo iwe paunoda sway kudzora ine yekuita vhiri.
- Inoshanda neLIPO 2S uye 3S mabhatiri. 3S inosarudzika (11,1V)
- Inosanganisira yekumisikidza yekuzvidzivirira kudzivirira kukundikana mune pyrotechnic chiteshi.
- Nhanhatu-axis IMU (BOSCH BMI088) uye altimeter (MS560702)
- Kadhi re SD kadhi kuti iwe ugone kusevha yako data.
- 16MB yekunze yekuchengetera flash. Sevha data panguva yekubhururuka (Kadhi re SD kadhi rinogona kunge risinganetsi panguva yekufamba nekuda kwekuzunguzika)
- Buzzer uye RGB Neopixel ma LED
- Kuwedzera UART uye I2C kubatana kana iwe uchida kubatanidza ekunze maseru seGPS module.
Pakupedzisira, kana iwe uchifarira kuziva zvakawanda nezvazvo yeiyo purojekiti iwe unogona kubvunza iwo ruzivo, emanyorero uye madhayagiramu Mune inotevera chinongedzo.
