Explication ya board ya PDB (Power Distribution Board) ya drone

Mokandimi ya mokanda oyo elimbisi ndenge ya kosalela ba power distribution boards (PDBs) na botongi ya ba drones. Ba PDBs bapɛtɔlɔki kosangisa ba nsinga mpe koyangela likebi ya puissance mpo na ba electronic speed controllers (ESCs), ba flight controllers, ba caméras, mpe ba composants mosusu. Kosalela PDB ebandisi bobongisi mpe bosembi ya système ya puissance ya drone na yo. Oyo ezali moko ya makambo ya ntina mingi mpo na kosala drone na nzela ya sembo mpe ya kitoko.

Tala ba ideas mosusu ya misala oyo ekoki kopesa litomba na kosalela PDB:

• Botongi ya quadcopter to hexacopter ya yo moko.
• Kosangisa caméra ya haute résolution mpo na photo ya likoló.
• Kobakisa émetteur vidéo FPV (First-Person View) mpo na koyangela mpɛpɔ na ntango ya solo.
• Kotia ba lumières LED mpo na komonana malamu na ba vols ya butu.

Matériel/Ba Composants

Mokanda oyo esalelaka ba types mibale ya ba power distribution boards: PDB passive (sans régulation ya tension) mpe PDB active (na ba sorties régulées ya 5V mpe 12V). (na vidéo na 00:08)

Okosalela mpe:

• Ba Electronic Speed Controllers (ESCs)
• Batterie (3-4 cellules LiPo ekomendami)
• Multimètre (mpo na ba mesures ya tension)
• Ba nsinga mpe ba connecteurs
• Ba LEDs (oyo ezali na choix)

Mokambi ya Kosangisa Ba Nsinga

PDB passive (na vidéo na 01:31) ezali na ba terminaux ya positif mpe négatif oyo ekomami polele. Ba terminaux nyonso ya positif esangisami na kati, ndenge moko mpe na ba terminaux nyonso ya négatif. Chaque ESC esangisami na pɛre ya positif mpe négatif. Ba connexions mosusu ezali mpo na ba LEDs mpe ba composants mosusu. (na vidéo na 01:39)

PDB active (na vidéo na 04:39) mpe ezali na ba terminaux ya positif mpe négatif mpo na kosangisa batterie mpe epesaka ba sorties régulées ya 5V mpe 12V. Board oyo ezali mpe na ba interrupteurs mpo na koyangela puissance na ba sorties ya 12V mpe 5V, mpe na choix, ba LEDs. (na vidéo na 03:37)

Limbisi ya Code

Code moko te esengeli mpo na misala oyo.

Misala ya Sika/Démonstration

Vidéo emonisaka kosangisa mpe komeka ba PDBs mibale. Mopesi ya lisolo asangisaka multimètre mpo na komeka tension na ba points ndenge na ndenge na ba boards, emonisaka bokabwani ya puissance mpe mosala ya ba régulateurs ya tension na PDB active. (na vidéo na 02:56)

Vidéo emonisaka kosalela ba interrupteurs mpo na koyangela puissance na ba sorties ya 12V mpe 5V mpe ba LEDs. (na vidéo na 03:37, 05:52) Mopesi ya lisolo alakisaka mpe ndenge ba tensions ndenge na ndenge ya batterie (lokola 15.5V na batterie ya 4 cellules) ekomi régulé mpo na kopesa ba sorties ya 5V mpe 12V oyo ezali sembo.
