2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
IR lub suab txav txav tau siv los hloov qhov hloov pauv ib txwm siv rau lub teeb & kiv cua hauv tsev. Qhov kev hloov Motion no yog siv kom tsis txhob muaj qhov xau tam sim no hloov pauv & zam qhov xwm txheej tam sim no. Hom khoom no uas yuav tsis ua tiav ntawm ib qho xwm txheej twg. Nov yog kuv thawj qhov kev qhia uas yuav yog qhov pheej yig dua.
Kauj Ruam 1: Sau Cov Khoom Siv:
Cov ntaub ntawv xav tau rau txoj haujlwm yog, 1. IC lm358 & cd4017.
2. IR Receiver (IR LED) thiab Transmitter.
3. Hloov pauv resistor 10k.
4. Resistors 220 ohm-2
10 k oh-os
100 hli-1
5.2 Txhua xim LED
6. Mov ci.
7. Jumper xov hlau.
8. 9v Roj Teeb.
Kauj Ruam 2: IR Sensor Ua Haujlwm & Circuit
IR sensor tsab ntawv tsa suab nrhiav tau siv hauv qhov kev hloov no. Lub ntsuas hluav taws xob no yuav kuaj pom cov khoom hla hla ob lub IR sensors uas yog IR xa mus (Tx) thiab IR txais (Rx). Thaum qhov khoom (Reflecting surface) raug kuaj pom IR tus neeg tau txais lub ntsej muag liab liab los ntawm IR coj thiab tom qab ntawd qhib lub Circuit Court. Tom qab ntawd qhov cuam tshuam ntawm kuv qhov haujlwm yog peb txhais tes.
Tom qab ntawd siv lub voj voog no rau txoj haujlwm.
Kauj ruam 3: Terminal (+, -) Txheeb cais
Ua ntej txuas raws li ib kab lus xub thawj paub cov dav ntawm cov khoom siv thiab nws txiav txim siab li cas hauv daim duab kos.
1. For LED, IR LED & IR tus neeg txais tos ntev dua yog lub davhlau ya nyob twg zoo thiab lwm cov hlau lead luv yog qhov tsis zoo.
2. Rau IC's Siv tus lej teeb tus lej.
3. Rau VR 10k chaw tus pin yog tso tawm thiab kawg tus pin siv raws li ib qho twg yog +ve lossis -ve.
Kauj Ruam 4: Ua kom tiav Thawj Lub Circuit Court
Thawj qhov Circuit Court yog IR sensor's IC lm358 Circuit.
Vcc tus pin 08 - +muaj lub davhlau ya nyob twg ntawm roj teeb
Gnd pin 04 - -ve davhlau ya nyob twg ntawm roj teeb
tus pin 02 - +ve davhlau ya nyob twg ntawm IR Rx
Txuas raws li daim duab qhia chaw kom tau txais kev siv LED tua thaum cov khoom hla lossis rov qab 2 & 3 tus pin ntawm IC lm358 kom tau txais qhov hloov pauv mus rau qhov siv LED. Xws li thaum cov khoom hla hla Ref LED yuav ci lossis lwm qhov tseem nyob hauv lub xeev.
Kuv tsis tau siv VR 10k, yog tias koj xav tau qhov rov qab tawm raws li kuv tau hais los saum no thov siv VR 10k.
Tom qab ua tiav thawj qhov kev kuaj xyuas seb IR tus xa hluav taws xob tau tso tawm cov duab hluav taws xob IR lossis tsis yog. Txhawm rau txheeb xyuas qhib koj lub xov tooj lub xov tooj ntse thiab tsom mus rau Ir coj thiab tam sim no koj tuaj yeem pom Ir coj ci zoo ib yam li kuv daim duab (cim ua IR tso tawm). Qhov no tsis tuaj yeem pom hauv peb lub qhov muag liab qab yam tsis muaj lub koob yees duab.
Kauj Ruam 5: Ua kom tiav Secondary Circuit
Qhov thib ob Circuit Court yog qhov yooj yim IC cd4017 kev sib txuas.
ie Vcc tus pin 16 - +ve davhlau ya nyob twg ntawm 9v roj teeb.
Gnd pin 08 - -ve termial ntawm 9v roj teeb.
pin 13 - Pin 08.
tus pin 04 - Pib dua tus pin 15.
tus pin 03 - Resistor 220ohm Uas yog rau peb lub teeb.
Thaum kawg clck tus pin 14 - Tus lej pin 01 ntawm IC lm358.
Tom qab ua tiav qhov Circuit Court koj qhov project yuav zoo li hauv daim vis dis aus. Txheeb ib yam li kuv seb ua haujlwm lossis tsis ua.
Kauj Ruam 6: Kev ua tiav ………………
Txuas lub hauv paus thiab theem thib ob los ua kom tiav txoj haujlwm.
Txuas tus IC cd4017's clck pin 14 - Tus lej pin 01 ntawm IC lm358.
tam sim no peb tes num tiav lawm.
Txuas qhov yooj yim txuas hluav taws xob hloov chaw ntawm Lub Teeb LED hauv Daim Duab Duab Circuit uas txuas nrog IC cd4017, Txhawm rau txuas tsev neeg 220v teeb lossis kiv cua ncaj qha rau hauv koj qhov haujlwm yam tsis muaj kev hloov pauv.
Kev ua haujlwm tag nrho thiab ua yeeb yaj kiab ntawm qhov haujlwm no yog hauv qab no.
