Nov yog qee yam kuv xav ua kom ntev. Tus oscillator nrog rab diav rawg hloov pauv ntawm LC, RC, siv lead ua lossis lwm yam resonator. Kuv tsis muaj (lossis kuv tsis tuaj yeem xav txog) daim ntawv thov siv tau rau nws. Kuv tsim nws kom lom zem xwb.

Kuv ua tsis tau ob peb zaug. Qhov teeb meem tsis yog yuav ua li cas txhawm rau kho lub resonate, lub tshuab hluav taws xob yooj yim li tus actuator ua txoj haujlwm. Qhov teeb meem yog yuav ua li cas thiaj paub qhov kev co rau cov lus tawm tswv yim.

Kauj ruam 1: Duab Interrupter

Kuv sim nrog HAL-sensors, coils thiab hlau nplaum. Ib txwm muaj kev cuam tshuam ntawm qhov sib nqus ntawm tus actuator yog qhov teeb meem. Tsis ntev los no kuv xav txog cov duab cuam tshuam, lawv tsawg kawg tsis nkag siab rau cov chaw sib nqus. Tab sis kuv tsis paub yog qhov kev co ntawm kev kho yuav txaus los ntsuas nrog cov duab cuam tshuam. Ntawm Ebay Kuv pom daim duab cuam tshuam nrog qhov sib txawv nruab nrab ntawm (IR) coj thiab yees duab transistor dav txaus kom tso cai rau ntawm txhais ceg ntawm rab diav rawg.

Nws ua haujlwm thawj zaug! Nrog me ntsis khoov rau pem hauv ntej thiab thim rov qab ntawm tus yees duab cuam tshuam (saib daim duab), txhais ceg ntawm lub diav rawg nyob zoo ib nrab ntawm cov coj thiab yees duab transistor. Cov ceg vibrating tsim txog 500mV ntawm lub teeb liab. Ob lub opamp ua kom nrov nrov thiab schmitt-ua rau lub teeb liab mus rau ib puag ncig yoj. Qhov no tau pub rau hauv lub teeb liab me me npn transistor uas tig mus rau thiab tawm npn lub zog transistor.

Nov yog lub teeb liab tawm los ntawm opamp thib ob. Raws li koj pom qhov zaus tsis yog qhov nws yuav tsum yog, 440 Hz. Suav rab diav rawg hauv Suav yog kwv yees li 1.5 Hz qis heev. Kuv tuaj yeem kho qhov ntawd los ntawm kev tshem tawm qee qhov ntev ntawm ob txhais ceg tab sis kuv tsis xav tias kuv yuav ua. (kom txo qis, ua ntawv me ntsis tawm qhov twg ob txhais ceg sib ntsib)
