Kev ceev thiab direty Sideway Ceeb toom system raws li lub tswv yim ib sab ntawm Tus Kheej Photonics ntawm Media Computing Group Aachen, pab nyiaj los ntawm tsoomfwv German kev kawm thiab kev tshawb fawb. Thaum twg los xij ib yam dab tsi los rau koj uas koj tsis hnov (yog vim lub ntsej muag tsis zoo lossis tsuas yog vim lub tsheb hluav taws xob nyob ntsiag to ntau dua li qub), qhov kev co ntawm koj txhais caj npab yuav tsum qhia rau koj tias koj yuav xav saib sab. 5 Kev co lub cev muaj zog (qhov tseeb tsuas yog siv peb leeg (tsav los ntawm ULN2803), lwm qhov yog thaub qab yog tias muaj qee yam tsis raug) tau siv txuas nrog peb lub VL53L1X qhov deb nrug. Lawv tau tswj hwm nrog Wattuino Pro Mini (3, 3V), roj teeb siv nrog duall AAA roj teeb pob. Cov tsev 3D luam tawm snap txhua yam ntawm lub dab teg.
Vim yog tshav ntuj thiab caj npab txav mus rau lub cev tsis ua haujlwm zoo hauv lub neej tiag tiag, tab sis tsawg kawg nws muaj kev lom zem los sim, peb tau kawm txuas ob peb lub sijhawm-ntawm-lub davhlau ya nyob twg ib zaug (ua tsaug rau Lukas Ossmann rau coding) thiab rov siv dua lub dab teg zoo rau qee yam zoo saib (ua tsaug rau Sophy Stönner ua tus tsim qauv).
Kauj ruam 1:
Thawj 3D luam tawm ntu hauv OpenScad teb. Txheeb ze thaum pib koj tuaj yeem pom - ib nrab tawm tswv yim tawm - ntu. Koj yuav tsum luam 3 zaug sensorHolderTop thiab holderBottom, ntxiv rau ib lub sijhawm tswjHolderTop thiab -Bottom. Tom qab ntawv luam ib zaug ntawm lub roj teeb (uas yuav xav tau hloov kho rau koj lub roj teeb pob siv). Cov yeeb yaj kiab ntxiv rau cov kab hluav taws xob thiab cov tshuab kev co yog los ntawm peb HaptiVision Toolkit, cov ntawv tsim qauv 3D tuaj yeem pom ntawm no. Yam tsawg kawg ntawm lub cav cav tuaj yeem hloov pauv nyob ntawm qhov kev co lub cev muaj zog, tab sis kuj tseem tuaj yeem pom qhov dav dav hloov pauv tau yooj yim.
Tom qab luam ntawv, xaws koj tus kheej lossis siv lub dab teg uas twb muaj lawm, qhov uas koj ua qhov rau cov neeg tuav ntxiv rau lub roj teeb pob, uas yuav muab xaws rau hauv.
Kauj ruam 2: Kev thaiv kab
Ua haujlwm me ntsis, tab sis hais ncaj ncaj rau pem hauv ntej: Ua ntej lub pcb me me tau muab tsoo rau ULN uas yog qhov pib siv tom qab ntawm tus tswj. Lub Vattery pob tau txuas nrog VDD thiab Gnd ntawm pawg tswj hwm, nrog rau txhua lub ntsuas. Tom qab ntawd txhua lub ntsuas hluav taws xob thiab lub rooj tswj hwm tau txuas nrog ua ke ntawm I2C npav. Ib lub xov hlau ntawm txhua tus Tsav Tsheb mus rau tus pin 3, 6 thiab 10 hla ULN tom qab, lwm qhov rau GND, thaum XSHUT ntawm txhua lub sensor mus rau A0, A1, A2 rau xaiv lub sensor.
Kauj Ruam 3: Tshaj Tawm Txoj Cai thiab Sim Nws Tawm
Thaum kawg, tus lej tuaj yeem raug rub tawm thiab kuaj qhov system. Muaj ntau txoj hauv kev xaiv siv lub ntsuas ntsuas, koj tuaj yeem hloov pauv ntawm qhov sib txawv ntawm qhov tsis sib xws nrog rau lub sijhawm ntsuas (txheeb xyuas lub sijhawm). Rau kev co lub zog tawm tswv yim sab saud thiab qis thershol tau siv, nrog rau lub tshuab lim dej rau lub suab nrov. B
Txhua lub ntsuas tau tshuaj xyuas ib qho tom qab ib qho los ntawm kev siv tus lej XSHUT rau tig lawv rau thiab tawm, tom qab ntawd lub sigbnal raug lim thiab lub zog ua kom muaj zog raug tswj raws qhov nrug nrog PWM.
