Kev piav qhia ntxaws ntawm UAV Davhlau Control Interface Connection Technology

Part 1: Dab tsi Cables yog siv rau Drone Flight Controller Interfaces?

Tus tswj lub davhlau, raws li "lub hlwb," xav tau kev sib txuas lus nrog ntau yam "kis" (cov khoom siv). Kev sib txuas cables feem ntau muab faib ua ob pawg: lub zog cables thiab cov teeb liab cables.

1. Teeb liab / Data Cables

DuPont Wires: Feem ntau siv cov kab txuas txuas. Lawv tuaj hauv ib qho -strand thiab ntau-strand ribbon cables.

Hom: Txiv neej-rau-txiv neej, txiv neej-rau- poj niam, poj niam-rau- poj niam. Flight controllers feem ntau siv 2.54mm pitch pins, yog li DuPont xov hlau yog cov qauv txuas.

Muaj nuj nqi: Siv los txuas lub davhlau maub los UART, I2C, SPI, RX / TX, thiab lwm yam teeb liab chaw nres nkoj rau receivers, cov duab kis tau tus mob, GPS li, LEDs, thiab lwm yam. Lawv feem ntau tsuas xa cov teeb liab, tsis yog lub zog loj.

Cov yam ntxwv: Slexible, yooj yim rau kev sib sau thiab hloov kho, tab sis tuaj yeem tshwm sim yooj yim thaum cov xov hlau tsis sib haum.

Flexible Ribbon Cables: Qee qhov sib xyaw ua ke ntawm lub davhlau tswj lossis cov khoom siv (xws li DJI cov duab xa mus, thiab qee lub koob yees duab nrog lub qhov (socket)) siv cov hlua txuas txuas nrog cov lej tshwj xeeb.

Muaj nuj nqi: Txuas ntau lub teeb liab thiab lub zog hluav taws xob ib zaug, zoo huv si thiab txhim khu kev qha.

Nta: Cov xov hlau zoo huv si, tab sis yuav tsum muaj cov cuab yeej zoo sib xws sib txuam, ua kev tu thiab hloov me ntsis nyuaj.

2. Fais fab Cables

Silicone Fais Fab Cables: Siv los txuas lub roj teeb mus rau lub zog loj ntawm lub davhlau tswj thiab ESC. Feem ntau thicker, muaj peev xwm nqa tau siab tam sim no.

Standard Wires: Siv rau cov khoom siv fais fab xws li receivers, cameras, image transmitters, and LEDs from the flight controller's power output port. Thinner hlau diam.

Qhov thib ob: Yuav tsum ua li cas rau Kev Sib Tw Sib Tw Drone?

Qhov no tsis yog ib qho yooj yim ntawm "txuas cov cables." Nws suav nrog cov txheej txheem ua haujlwm hauv ob qho tib si kho vajtse thiab software kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm.

Hardware Processing Techniques

1. Cov txuj ci Soldering: Qhov no yog ib qho txuj ci tseem ceeb hauv kev sib tw drone sib dhos.

Flight Controller Pads: Feem ntau cov sib tw drone davhlau controllers xav kom koj ncaj qha solder lub cev muaj zog ESC teeb liab kab, receiver kab, thiab lwm yam. Cov pob qij txha yuav tsum du, ruaj, tsis muaj cov pob qij txha los yog luv luv.

1. Fais fab Cable Soldering: Siab- cov xov hlau tam sim no yuav tsum tau muab qhwv rau lub hwj chim input pads los ntawm lub ntsiab roj teeb cable mus rau lub davhlau maub los, thiab los ntawm lub davhlau tswj mus rau ESC. Xyuas kom cov pob qij txha tau ruaj khov.

2. Thaum tshav kub kub Shrink Tubing: Insulate tag nrho cov solder pob qij txha (tshwj xeeb tshaj yog lub zoo thiab tsis zoo lub hwj chim terminals) nrog tshav kub shrink tubing los tiv thaiv luv luv circuits.

3. Interface Identification thiab Txhais:

Xa mus rau phau ntawv tswj lub davhlau! Nkag siab txog kev ua haujlwm ntawm txhua lub ncoo/socket.

Kom meej meej txhais cov ntsiab lus interface (VCC, GND, Signal) rau cov khoom siv (receiver, video transmitter, thiab lwm yam).

4. Kab lis kev cai:

Tsis txhob cuam tshuam los ntawm lub hwj chim cables rau cov teeb liab cables: Khaws cov teeb liab cables (xws li receiver antennas thiab video transmitter signal cables) deb ntawm lub hwj chim cables thiab lub cev muaj zog cables. Yog tias hla tsis tau, hla perpendicularly thaum twg los tau.

Kev ruaj ntseg thiab ruaj ntseg Cables: Kev ruaj ntseg cables nrog cable ties, hluav taws xob daim kab xev, los yog kub kua nplaum los tiv thaiv kev co thaum lub sij hawm davhlau los ntawm ua rau desoldering los yog luv luv circuits.

Kav hlau txais xov tuav: Lub receiver thiab video transmitter kav hlau txais xov yuav tsum tau muab cia kom deb ntawm cov pa roj carbon fiber fuselage (carbon fiber yuav tiv thaiv cov teeb liab) thiab ruaj ntseg zoo.

4. Fais fab mov:

Voltage Matching: Paub meej tias qhov kev khiav hauj lwm voltage ntawm tag nrho cov cuab yeej thiab kos lub hwj chim los ntawm qhov tseeb BEC tso zis chaw nres nkoj ntawm lub davhlau maub los. Tsis txhob txuas qhov hluav taws xob ntau tshaj qhov khoom siv tiv thaiv hluav taws xob.

Filtered Power Supply: Yog hais tias siv analog video kis tau tus mob, nws yog qhov zoo tshaj plaws los kos lub hwj chim ntawm lub davhlau tswj lub lim fais fab chaw nres nkoj kom txo cov video daus los ntawm lub hwj chim mov suab nrov.

Software Configuration Techniques

1. Chaw nres nkoj qhib thiab teeb tsa:

Hauv parameter tuning software, koj yuav tsum qhib thiab teeb tsa UART chaw nres nkoj koj siv.

Piv txwv li: Configure UART2 li "Serial Receiver" rau txuas tus txais; configure UART1 li "Video Transmission/MSP" rau kev sib txuas cov video kis tau tus mob los yog configuring ntse suab.

2. Kev xaiv raws tu qauv:

Txais Tus Txheej Txheem: Hauv "Tsev Txais" tab, xaiv cov txheej txheem uas phim koj tus txais.

Video Transmission Protocol: Yog tias siv digital video kis tau tus mob, koj yuav tsum teeb tsa thiab tswj nws siv cov txheej txheem kom raug.

3. Fault Protection Settings:

Kev teeb tsa tus cwj pwm hauv software thaum lub receiver poob teeb liab (xws li tsis siv neeg tsaws lossis rov qab mus tsev) yog ib kauj ruam tseem ceeb rau kev nyab xeeb. Cov txheej txheem kev sib txuas thiab kev kuaj xyuas kev nyab xeeb

1. Fais fab kev khiav hauj lwm: Ib txwm disconnect lub roj teeb ua ntej muaj kev sib txuas ntawm hardware los yog soldering.

2. Txuas ib qho los ntawm ib qho, Fais fab rau maj mam: Nws raug nquahu kom siv tsuas yog cov khoom siv hluav taws xob thiab lub tshuab txais ua ntej, tom qab ntawd muab lub hwj chim rau thiab sim kev sib txuas ntawm lub davhlau tswj thiab cov chaw taws teeb tswj. Tsuas yog txuas lub cuab yeej tom ntej tom qab kev sib txuas ua tiav.

3. Voltage Check: Siv ib lub multimeter los xyuas seb qhov voltage ntawm txhua qhov hluav taws xob tso zis qhov chaw nres nkoj ntawm lub davhlau tswj yog qhov qub.

4. Kev Ntsuam Xyuas Teeb Meem: Tshawb xyuas hauv qhov ntsuas qhov ntsuas software seb lub teeb liab receiver teb puas yog, thiab seb lub cev muaj zog thiab kev sib hloov puas yog.

5. Rwb thaiv tsev Check: Muab ob npaug rau- xyuas tias tag nrho cov khoom siv hluav taws xob thiab cov hlau xaus yog insulated.
