Iyo Yekupedzisira Inotungamira kuPCB Prototyping Uchishandisa Real-Nguva Kudzora Masystem

Nhanganyaya:

Prototyping akadhindwa edunhu mabhodhi (PCBs) uchishandisa chaiyo-nguva yekudzora masisitimu inogona kuve yakaoma uye inotyisa basa. Nekudaro, nemidziyo yakakodzera, ruzivo, uye matekiniki, maitiro anogona kupedzwa zvinobudirira.Mugwaro rino rakazara, tichakufamba iwe nematanho ekutanga uye akanakisa maitiro ekuita prototyping maPCB uchishandisa chaiyo-nguva yekudzora masisitimu.Kunyangwe iwe uri nyanzvi yeinjiniya kana yemagetsi hobbyist, iyi blog inokupa iwe ruzivo rwunodiwa kuti uchinje pfungwa dzako dzePCB kuita chokwadi.

1. Nzwisisa PCB prototype dhizaini:

Usati wanyura munyika yechaiyo-nguva yekudzora masisitimu, zvakakosha kuti uzive izvo zvekutanga zvePCB prototyping. PCBs chinhu chakakosha chemidziyo yakawanda yemagetsi, inopa hubhu yekubatanidza uye maseketi. Kuti unyatso prototype PCBs, unofanirwa kunzwisisa maitiro ekugadzira, PCB maseru, zvikamu, uye maitiro ekugadzira. Ruzivo urwu ruchaita hwaro hwekubatanidza chaiyo-nguva yekudzora masisitimu mumaPCB.

2. Sarudza maturusi akakodzera uye zvikamu:

Kufananidzira PCB uchishandisa chaiyo-nguva yekudzora sisitimu, unofanirwa kusarudza maturusi akakodzera uye zvikamu. Kutanga, iwe unoda yakavimbika PCB dhizaini software inopa chaiyo-nguva simulation kugona. Dzimwe dzakakurumbira software sarudzo dzinosanganisira Eagle, Altium, uye KiCad. Tevere, sarudza microcontroller kana processor inokodzera zvaunoda purojekiti. Sarudzo dzakajairika dzinosanganisira Arduino, Raspberry Pi, uye FPGA mabhodhi.

3. Dhizaini PCB marongero:

PCB dhizaini inoita basa rakakosha mukubatanidzwa kwakabudirira kweiyo chaiyo-nguva yekudzora masisitimu. Ita shuwa kuti zvikamu zvakamisikidzwa zvine hungwaru kuti zvideredze kukanganiswa kwechiratidzo uye kukwenenzvera kuita. Funga nezvezvinhu zvakadai sekutsvaga kureba, simba uye ndege dzepasi, uye kupera kwekushisa. Shandisa EDA (Electronic Dhizaini otomatiki) maturusi ekubatsira nehurongwa hwekugadzirisa uye kuwedzera mugadziri-akapihwa dhizaini mitemo kudzivirira zvakajairika kugadzira nyaya.

4. Yakasanganiswa nechaiyo-nguva yekudzora system:

Real-time control masisitimu anogona kunyatso tarisa uye kudzora zvigadzirwa zvemagetsi. Kuti ubatanidze sisitimu yakadaro kuita PCB dhizaini, unofanirwa kunzwisisa dzakasiyana siyana dzekutaurirana senge SPI, I2C, UART, uye CAN. Aya mainterface anogonesa kusangana kusina musono nemasensor, actuators, uye mamwe maperipheral. Zvakare, nzwisisa mitauro yekuronga seC/C++ nePython sezvo inowanzoshandiswa kunyora firmware inomhanya pane microcontrollers.

5. Kuedza uye kudzokorora:

Kana prototype yagadzirira, zvakakosha kuti unyatso kuyedza kuita kwayo. Shandisa maturusi ekugadzirisa uye software kuti ive nechokwadi chekuti-chaiyo-nguva yekudzora masisitimu anoshanda sezvaitarisirwa. Edza akasiyana mamiriro ekuona kuverenga kwe sensor uye kuve nechokwadi chekutonga kwakaringana. Kana paine nyaya dzikamuka, ongorora dambudziko uye ramba uchidzokorora kudzamara wawana kuita kwaunoda.

Mhedziso :

Prototyping PCBs ine chaiyo-nguva yekudzora masisitimu inovhura mikana isingaperi yekugadzira zvigadzirwa zvemagetsi zvitsva. Nekutevera maitiro akaiswa, kushandisa maturusi akakodzera, uye kugara uchidzidza uye uchidzokorora, unogona kushandura mazano ako kuita zvizere prototypes. Gamuchira dambudziko, iva nemoyo murefu, uye unakirwe nemaitiro ekushandura PCB yako dhizaini kuita chokwadi.
