Chengetedza Kamera Prototyping: Iyo Yakakwana Nhungamiro yePCB Dhizaini

suma:

Munyika yanhasi inomhanya-mhanya, makamera ekuchengetedza ave chikamu chakakosha chekuchengetedza dzimba dzedu, mabhizinesi nenzvimbo dzeveruzhinji. Sezvo tekinoroji ichifambira mberi, ndizvo zvinoitawo kudiwa kwehunyanzvi uye kwakanyatso chengetedza kuchengetedza kamera masisitimu. Kana iwe uchifarira zvemagetsi uye unofarira zvekuchengetedza masisitimu, unogona kunge uchizvibvunza iwe:"Ndinogona kuratidza PCB yekamera yekuchengetedza?" Mhinduro ndeyokuti hongu, uye mune ino blog, tichakufambisa iwe kuburikidza nemaitiro akagadzirirwa kuSecurity kamera PCB (yakadhindwa redunhu bhodhi) dhizaini uye prototyping maitiro.

Dzidza izvo zvekutanga: Chii chinonzi PCB?

Usati wanyura mukati mekukasira kwekuchengetedza kamera PCB prototyping, zvakakosha kuve nekunzwisisa kwekutanga kweiyo PCB chii. Zvichitaurwa zviri nyore, PCB inoshanda semusana wezvikamu zvemagetsi, ichizvibatanidza pamwe chete nemichina uye nemagetsi kuti iite dunhu rinoshanda. Inopa compact uye yakarongeka chikuva chezvikamu kuti zvigadzirwe, nokudaro kuderedza kuoma kwedunhu richiwedzera kuvimbika kwayo.

Kugadzira PCB Yekuchengetedza Makamera:

1. Conceptual dhizaini:

Nhanho yekutanga mu prototyping yekuchengetedza kamera PCB iri kutanga neiyo conceptual dhizaini. Sarudza iwo chaiwo maficha aunoda kuwedzera, akadai sekugadzirisa, kuona kwehusiku, kuona kufamba, kana PTZ (pan-tilt-zoom) mashandiro. Tsvagurudza iripo yekuchengetedza kamera masisitimu kuti uwane kurudziro uye mazano ega dhizaini yako.

2. Magadzirirwo ehurongwa:

Mushure mekufunga dhizaini, nhanho inotevera ndeyekugadzira iyo schematic. A schematic iratidziro inomiririra yedunhu remagetsi, inoratidza kuti zvikamu zvakabatanidzwa sei. Shandisa zvishandiso zvesoftware seAltium Designer, Eagle PCB kana KiCAD kugadzira uye kutevedzera PCB marongero. Ita shuwa kuti schematic yako ine zvese zvinodiwa senge ma sensors emifananidzo, microcontrollers, magetsi regulators, uye zvinobatanidza.

3. PCB dhizaini:

Kana iyo schematic yapera, yave nguva yekuchishandura kuita chimiro chePCB chemuviri. Iyi nhanho inosanganisira kuisa zvikamu pane redunhu bhodhi uye routing inodiwa yekubatanidza pakati pavo. Paunenge uchigadzira yako PCB dhizaini, funga zvinhu zvakaita sechiratidzo chekutendeseka, kuderedza ruzha, uye kutonga kwekupisa. Ita shuwa kuti zvikamu zvakaiswa zvine hungwaru kuti zvideredze zvinovhiringa uye optimize kushanda.

4. PCB kugadzirwa:

Paunenge uchinge wagutsikana nePCB dhizaini, inguva yekuvaka bhodhi. Export Gerber mafaira ane ruzivo runodiwa nevagadziri kugadzira PCBs. Sarudza yakavimbika PCB mugadziri anogona kuzadzisa dhizaini zvaunoda uye zvirevo. Munguva iyi, teerera kune zvakakosha zvinhu senge layer stackup, ukobvu hwemhangura, uye solder mask, sezvo zvinhu izvi zvinogona kukanganisa zvakanyanya kuita kwechigadzirwa chekupedzisira.

5. Gungano uye kuyedzwa:

Kana wangogamuchira PCB yako yakagadzirwa, yave nguva yekuunganidza zvinhu pabhodhi. Maitiro acho anosanganisira kutengesa zvinhu zvakasiyana senge ma sensors emifananidzo, microcontrollers, majoini, uye magetsi ekudzora paPCB. Kana gungano rapera, nyatso edza kushanda kwePCB kuti uve nechokwadi chekuti zvikamu zvese zviri kushanda sezvazvinotarisirwa. Kana paine nyaya dzaonekwa, dzigadzirise usati waenda kune chinhanho chinotevera.

6. Kugadziriswa kweFirmware:

Kuunza maPCB kuhupenyu, kuvandudza firmware kwakakosha. Zvichienderana nekwaniso uye maficha ekuchengetedza kamera yako, ungangoda kugadzira firmware inodzora zvinhu zvakaita sekugadzirisa mifananidzo, kufambisa kwekuona algorithms, kana vhidhiyo encoding. Sarudza pane yakakodzera programming mutauro kune microcontroller yako uye shandisa IDE (Integrated Development Environment) yakadai seArduino kana MPLAB X kuronga firmware.

7. Kubatanidzwa kweSystem:

Kana iyo firmware ikabudirira kugadzirwa, iyo PCB inogona kubatanidzwa mune yakazara yekuchengetedza kamera system. Izvi zvinosanganisira kubatanidza PCB kune inodiwa peripherals senge lenzi, dzimba, IR lluminators uye magetsi ekushandisa. Ita shuwa kuti zvese zvinongedzo zvakasimba uye zvakanyatsoenderana. Kuyedzwa kwakakura kunoitwa kuratidza kushanda uye kuvimbika kweiyo yakabatanidzwa system.

Mukupedzisa:

Prototyping a PCB yekamera yekuchengetedza inoda musanganiswa weruzivo rwehunyanzvi, kusika, uye kutarisisa kune zvakadzama. Nekutevera matanho akatsanangurwa mune ino blog, unogona kushandura mazano ako kuti ave echokwadi uye kugadzira inoshanda prototype kune yako yekuchengetedza kamera system. Ramba uchifunga kuti dhizaini uye prototyping maitiro anogona kusanganisira iteration uye kunatsiridza kusvika mhedzisiro yaunoda yawanikwa. Nekutsunga uye kutsungirira, iwe unogona kubatsira kumunda unoramba uchikura wekuchengetedza kamera masisitimu. Happy prototyping!
