Kab lus no qhia koj yuav ua li cas ua cov khoom siv transistor vibrator.

Lub voj voos tig rau ntawm tus neeg ua haujlwm vibrator thaum lub teeb liab ultrasonic nkag mus rau lub sensor.

Thawj Circuit Court yog tus txais ultrasonic. Qhov thib ob Circuit Court yog tus tsav tsheb vibrator.

Kuv siv lub tshuab txais ultrasonic los ntawm kab lus no:

Khoom siv

Cheebtsam: ultrasonic sensor - 3, transistors ntau zaus - 5, lub hom phiaj transistors - 5, lub zog transistor/darlington khub - 2, cov cua sov - 1, matrix board - 1, insulated xov hlau, hlau hlau - 1 mm lossis 0.9 mm, 100 ohm resistors (lub zog siab) - 10, 1 kohm resistors - 10, 470 nF capacitors - 10, 100 kohm resistors - 5, 470 uF capacitors - 5, ultrasonic transmitter (koj tuaj yeem siv qee yam ultrasonic senr).

Cov cuab yeej: USB oscilloscope, pliers, hlau stripper, ultrasonic teeb liab generator.

Cov khoom siv xaiv tau: kab laug sab, nkag/lub thawv, LED/ci LED - 3.

Yeem cov cuab yeej: cov hlau txuas.

Kauj ruam 1: Tsim Circuit Court

Qhov tsawg kawg nkaus transistor cov khoom siv hluav taws xob hla rau Darlington khub lub zog transistor yuav yog 0.9 V. Yog li qhov siab tshaj plaws hla LED yuav yog 2.1 V.

Yog tias koj hloov pauv Darlington khub transistor nrog lub zog transistor (txhawm rau txo tus nqi ntawm cov khoom siv) tom qab ntawd koj yuav tsum txuas rau 100-ohm resistor hauv koob nrog LED vim tias qhov tsawg kawg nkaus transistor cov khoom siv hluav taws xob tuaj yeem poob qis dua 0.2 V.

Kauj Ruam 2: Simulation

Lub xov tooj cua txais ultrasonic zoo li muaj qhov ncua sij hawm 100 ms. Qhov ua rau ON los ntawm 0 vib nas this, sawv cev ntawm lub xub ntiag ntawm lub teeb liab ultrasonic (duab plaub liab hauv thawj daim duab). Txawm li cas los xij, lub Circuit Court tab tom tsim AC cov zis 100 ms tom qab.

Qhov kev sim ua ntu zus qhia qhov me me bandwidth vim tias PSpice simulation software cov tub ntxhais kawm ntawv tsab tsis muaj xov tooj cua zaus transistors. Txawm li cas los xij, tus neeg txais ultrasonic yuav tseem ua haujlwm nrog cov hom phiaj dav dav transistors.

Qhov tsawg kawg Darlington khub cov khoom siv hluav taws xob poob qis txog li 0.6 V. Qhov ntawd txhais tau tias tus qauv transistor tsis raug.

Qhov siab tshaj tam sim no hla tus vibrator yog li 24 mA. Txawm li cas los xij, kuv tus qauv ntawm tus vibrator (100-ohm resistor) tuaj yeem tsis raug.

Kauj Ruam 3: Ua Circuit Court

Kev ua ntawm Circuit tau ncua rau ntau lub lis piam vim qee yam khoom siv tsis muaj rau tus tsav tsheb vibrator.

Lub hauv paus resistor (Rb1 thiab Rb2) yuav tsum tau hloov kho rau qhov tshwj xeeb transistor tam sim no nce. 150 kohm tus nqi Rb1 thiab Rb2 resistors yuav tsis haum.

Kauj ruam 4: Xeem

Kuv txuas cov khoom siv hluav taws xob ultrasonic ncaj qha rau kuv lub tshuab hluav taws xob teeb liab. Koj tuaj yeem ua koj tus kheej lub cim hluav taws xob nrog lub 555 lub sijhawm thiab tsawg kawg yog 9 V fais fab mov.

Kuv kuj tau ua lub qhov me me hauv lub hnab yas txais kom txhim kho kev nthuav tawm ntawm ultrasonic nthwv dej.

LED ci tig rau thaum lub teeb liab ultrasonic tau thov rau lub ntsuas. Koj yuav tsum nce ntim kom hnov lub vibrator.
