SensorsPuas yog kev paub txog kev paub thiab thev naus laus zis-siv tau cuam tshuam nrog ntau hom lus. Ntawm no yog cov lus qhia luv luv rau cov qauv siv tam sim no siv.
Ua ntej, raws li lub tshuab ua haujlwm ntawm lub sensor, nws tuaj yeem faib ua lub hauv paus ntawm lub cev, cov kev cai lij choj uas yog txoj cai kev txuag, thiab kev cai lij choj ntawm kev txheeb cais.
Thib ob, raws li lub hauv paus ntsiab lus ntawm kev sib xyaw, nws tuaj yeem faib ua ob pawg: hom qauv hom thiab hom lub cev.
Cov txheej txheem txheej txheem txheej txheem yog raws cov kev cai ntawm kev ua haujlwm, suav nrog cov qauv ntawm kev ua haujlwm yog qhov kev hloov pauv ntawm cov chaw ua haujlwm. sensor, dua li qhov hloov ntawm cov khoom siv khoom.
Cov cuab yeej ntawm lub cev tau tsim kho raws li txoj cai ntawm kev cai lij choj thiab Ohm txoj kev cai lij choj thiab txoj cai ntawm teeb meem uas qhia qee lub hom phiaj ntawm cov teeb meem ntawm teeb meem. Feem ntau ntawm cov cai no tau muab nyob rau hauv daim ntawv ntawm constants ntawm cov khoom nws tus kheej. Qhov loj ntawm cov kev txiav txim siab tas li txiav txim siab qhov ua tau zoo ntawm lub sensor. Yog li ntawd, kev ua yeeb yam ntawm cov cuab yeej siv lub cev sib txawv nrog cov neeg sib txawv ntawm cov khoom siv sib txawv, uas siv cov teeb meem sab nraud, uas siv cov kev cai sab nraud ntawm txoj cai ntawm teeb meem. Pom tseeb, nws cov yam ntxwv yog ze ze rau cov khoom siv uas siv cov kev hloov pauv ntawm cov hlau, thiab lwm yam, yog los ntawm kev hloov ib puag ncig ib puag ncig, yog txhua tus sensors ib puag ncig. Ib qho ntxiv, tseem muaj cov sensors raws li kev txuag kev cai thiab cov cai tswjhwm, tab sis lawv yog ob peb. tsawg dua.
Thib peb, raws li lub zog hloov ntawm lub sensor, nws tuaj yeem faib ua ob pawg: Zog tswj hom khoom.
Zog Tswj Hom Sensor, nyob rau hauv cov txheej txheem ntawm cov ntaub ntawv hloov, nws lub zog xav tau lub zog sab nraud. Xws li tsis kam, inductance, capacitance, thermal kuj mob, siv cov nyhuv uas muaj yees duab, thiab lwm yam.
Lub zog hloov dua siab tshiab sensor feem ntau yog tsim ntawm lub zog hloov dua siab tshiab, thiab nws tsis tas yuav muaj lub zog sab nraud. Piv txwv li, sensors raws li cov nyhuv piozoelectric, pyroelectric nyhuv, photoelectromotive quab yuam nyhuv, thiab lwm yam li cov sensors.
Plaub, raws li lub ntsiab cai lub cev, nws tuaj yeem faib ua
1) Hluav taws xob lub tshuab hluav taws xob etoror. Suav nrog peb daim ntawv yooj yim: tsis kam, inductive, thiab muaj peev xwm.
2) Magnetoelectric sensor. Suav nrog Magneto-hluav taws xob induction hom, Hall hom, sib nqus phiaj xwm, thiab lwm yam.
3) Piezoelectric sensor.
4) Lub photoelectric sensor. Xws li hom photating hom, grating hom, laser hom Disc Disc Hom, Hom Tshuaj Fiber, Tsis Muaj Zog, Cov Yeeb Yam, thiab lwm yam.
5) Pneumatic Sensor
6) pyroelectric sensor.
7) yoj sensor. Suav nrog ultrasonic, microwave, thiab lwm yam.
8) ray sensor.
9) semiconductor hom sensor.
10) sensors ntawm lwm cov ntsiab cai, thiab lwm yam.
Tus txheej txheem ua hauj lwm ntawm qee cov sensors muaj daim ntawv sib xyaw ntau tshaj ob lub hauv paus ntsiab lus. Piv txwv li, ntau semiconductor sensors kuj tseem tuaj yeem pom raws li hluav taws xob cov ntsuas hluav taws xob.
Qhov thib tsib, cov thawj coj tuaj yeem raug cais raws li lawv lub hom phiaj, xws li cov sensors, sensors siab, sensors rau kev co, thiab yog li ntawd.
In addition, according to whether the sensor output is an analog signal or a digital signal, it can be divided into analog sensors and digital sensors. Raws li kev hloov dua siab tshiab tau thim rov qab, nws tuaj yeem faib ua cov sensors thiab unidirectional sensors.
Ntau sensors, vim muaj cov ntsiab cai sib txawv thiab cov qauv siv sib txawv, lawv cov lus qhia sib txawv yog qhov zoo ib yam, suav nrog: ① kev ntseeg tau; ② qhov raug zoo li qub; ③ dynamic kev ua tau zoo; Sensitivity; daws teeb meem; ⑥ Tej yam; ⑦ anti-cuam tshuam muaj peev xwm; (⑧ Kev Siv Zog; ⑨ nqi; cuam tshuam ntawm cov khoom, thiab lwm yam.
Qhov yuav tsum tau ua rau kev ntseeg tau, qhov raug zoo li qub, kev ua tau zoo, thiab ntau yog tus kheej. Sensors ua tiav lub hom phiaj ntawm ntau qhov ntsuas los ntawm kev nrhiav haujlwm. Muaj ntau lub sensors yuav tsum ua haujlwm nyob rau hauv kev ua neej nyob rau hauv kev ua haujlwm zoo, thiab tag nrho cov chaw ua haujlwm tsis txaus, yog qhov tsis zoo, lossis qhov tsis zoo. Yog tias ib lub ntsuas tsis txaus, nws yuav cuam tshuam rau qhov xwm txheej tag nrho. Yog li ntawd, kev ntseeg tau ua haujlwm, qhov raug zoo li qub thiab kev cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam nrog qhov xwm txheej, thiab muaj ntau yam kev npaj txhij txog yuav tshwm sim. Yog li ntawd, lub sensor yuav tsum muaj qhov yoog raws li txoj kev hwm no, yog li kom zam dhau ib qho kev siv rau ib zaug thiab ua tiav lub hom phiaj ntawm kev tau txais ob zaug tshwm sim nrog ib nrab ntawm lub dag zog. Muaj ob peb lwm yam yuav tsum tau piav qhia tus kheej thiab yuav tsis hais txog ntawm no.
