- Mafunso Ofunsidwa Kawirikawiri 6: Kodi mumapereka chithandizo chaukadaulo mukamaliza kubereka?
- Chidziwitso cha Uinjiniya
Mu mpikisano wa FPV, kujambula mafilimu amlengalenga, ndi ntchito za UAV zamafakitale, magwiridwe antchito a drone module amatsimikizira kupambana. Ku Rich Full Joy, timaphatikiza zaka zoposa 20 zaukadaulo wa PCB/PCBA ndi luso lapadera la kapangidwe ka UAV kuti tipange owongolera ndege odalirika kwambiri, ma ESC, ndi machitidwe a VTX okhala ndi malo ovuta.
Mafunso Ofunsidwa Kawirikawiri 1: Ndi mitundu iti ya ma drone modules omwe mumapereka?
Timapereka ma module othamanga kwambiri a FPV, ma UAV oyendetsedwa ndi AI, ndi ntchito zamafakitale:
- Owongolera Ndege (FCs) - Kulumikizana kwa masensa ndi kukhazikika kwa ndege
- Olamulira Liwiro Lamagetsi (ESCs) - Kulamulira liwiro la injini
- Mabodi Ogawa Mphamvu (PDBs)
- Makina Otumizira Makanema (VTX) - Kanema wa HD wocheperako
- Magawo a GPS ndi Kuyenda
- Ma Flight Stacks Ogwirizana - Kuphatikiza kopangidwa kale
Imagwirizana ndi Holybro Kakute, Matek F7/F4, SpeedyBee, T-Motor, Hobbywing XRotor, ndi Foxeer Reaper. Imathandizira STM32F743, STM32F722, STM32F405, ndi STM32H743 MCUs.
Mafunso Ofunsidwa Kawirikawiri: Kodi mungathandizire kapangidwe ka module ya drone yopangidwa mwamakonda?
Inde. Ntchito zathu za ODM/OEM zimaphimba:
- Kapangidwe ka Zipangizo: Mapangidwe a PCB apadera, ma RF circuits, kasamalidwe ka mphamvu
- BOM yonse: Kupeza zinthu mogwirizana ndi ROHS/REACH
- Firmware & Mapulogalamu: Kuphatikizika kwa Betaflight, ArduPilot, PX4
- Zolemba: Mafayilo a Gerber, zojambula, mitundu ya 3D CAD
- Kuyesa: EMI/EMC, kutentha, kutsimikizika kwa kugwedezeka
Kafukufuku: Ma STM32F743 FC opangidwa mwamakonda okhala ndi 60A ESCs adachepetsa kulemera ndi 18% ndipo adakulitsa kuchedwa ndi 25%.
Mafunso Ofunsidwa Kawirikawiri 3: Kodi ma module anu amagwirizana ndi nsanja za UAV zotseguka?
Yogwirizana kwathunthu ndi:
- PX4 - Ma UAV amalonda/ofufuza
- ArduPilot - Ntchito zodziyimira pawokha
- Betaflight - mpikisano wa FPV
- iNav - Kuyenda pa GPS
Ubwino: Kuchepetsa nthawi yolumikizirana, zosintha za firmware, komanso kusinthasintha kwa makina osakanizidwa.
Mafunso Ofunsidwa Kawirikawiri 4: Kodi nthawi yoyambira kupanga zitsanzo ndi kupanga zinthu zambiri ndi iti?
- Zitsanzo: Masiku 7 ogwira ntchito
- Kupanga Kwambiri: Masabata 2–4
- Maoda Ofulumira: Kuthamanga kulipo
Kuchita bwino: Ma STM32 MCU omwe adasungidwa kale achepetsa nthawi yopangira maoda obwerezabwereza ndi 30%.
Mafunso Ofunsidwa Kawirikawiri 5: Kodi mumatsimikiza bwanji kuti PCB ndi yodalirika pazochitika zovuta kwambiri?
Zitsimikizo zikuphatikizapo:
- Kudalirika kwa Makina: Mayeso a kugwedezeka/kugwa
- Kukhazikika kwa Kutentha: -20°C mpaka +85°C
- Chitetezo cha Zachilengedwe: Chophimba/kuphimba m'miphika
- Kukhulupirika kwa Chizindikiro: Zotsatira zolamulidwa ndi Impedance
- Miyezo: Kupanga kwa IPC Class 3
Mafunso Ofunsidwa Kawirikawiri 6: Kodi mumapereka chithandizo chaukadaulo mukamaliza kubereka?
Chithandizo pambuyo pobereka chimaphatikizapo:
- Kuthetsa Mavuto Patali
- Zosintha za Firmware
- Thandizo Lophatikizana
- Kukonza Mwamakonda
Chidziwitso cha Uinjiniya
- Ma MCU Owongolera Ndege: STM32F405 (otsika mtengo) poyerekeza ndi STM32F743/STM32H743 (ogwira ntchito bwino kwambiri)
- Firmware ya ESC: BLHeli_32 (yotchuka) poyerekeza ndi AM32 (yamphamvu kwambiri)
- Zipangizo za PCB: Rogers (VTX yocheperako) vs FR-4 (yotsika mtengo)
Ndi zaka zoposa 20 zaukadaulo wa PCB/PCBA, Rich Full Joy imapereka kapangidwe, kupanga, ndi kuphatikiza zamagetsi a drone odalirika kwambiri.
Lankhulani ndi Mainjiniya Athu Musanasankhe
Tathandiza opanga ma drone oposa 150 ku Europe, Middle East, ndi ku US kupanga ma PCB stackups oyenera cholinga. Kaya simukudziwa bwino za kutayika kwa dielectric, ma thermal coefficients, kapena kukhazikika kwa lamination, tili pano kuti tikuthandizeni.
