Reed hloov - QHOV TSEEB

Reed hloov tau tsim nyob rau xyoo 1936 los ntawm Walter B. Ellwood hauv Tswb Xov Tooj Hu Xov Tooj. Reed Hloov muaj ib khub ntawm ferromagnetic (qee yam yooj yim rau magnetize raws li hlau) hloov pauv cov hlau sib xws feem ntau npib tsib xee-hlau hlau (raws li lawv yooj yim rau magnetize thiab tsis nyob magnetized ntev) cais los ntawm tsuas yog ob peb microns, coated nrog cov hlau hnyav hnyav xws li Rhodium lossis Ruthenium (Rh, Ru, Ir, lossis W) (kom muab lawv lub neej ntev raws li lawv hloov thiab tawm) hauv lub hnab ntim kaw (airtight) iav lub hnab (kom lawv muaj hmoov av thiab av dawb). Cov iav raj muaj cov pa roj inert (Cov pa roj inert yog cov pa uas tsis ua rau muaj tshuaj lom raws li cov txheej txheem muab) feem ntau yog Nitrogen lossis thaum muaj hluav taws xob siab nws tsuas yog lub tshuab nqus tsev yooj yim.

Kauj ruam 1:

Hauv kev tsim khoom, cov raj hlau tau muab tso rau hauv txhua qhov kawg ntawm lub raj iav thiab qhov kawg ntawm lub raj cua sov kom nws ntsaws ib ncig ntawm ib feem ntawm cov ceg ntoo. Cov xim ntsuab-xim Infrared-nqus iav tau siv ntau zaus, yog li cov duab hluav taws xob cua sov tuaj yeem tsom mus rau cov cua sov hauv thaj chaw me me ntawm lub raj iav. Cov iav siv yog cov hluav taws xob tiv taus siab heev thiab tsis muaj cov khoom hloov pauv xws li cov hlau lead oxide thiab cov tshuaj fluorides uas tuaj yeem kis tus neeg sib tiv thaum lub sijhawm ua haujlwm sib khi. Cov coj ntawm qhov hloov pauv yuav tsum tau ua tib zoo txhawm rau tiv thaiv kom tawg lub hnab ntawv iav.

Thaum cov hlau nplaum raug coj los ze rau ntawm cov neeg sib cuag, lub tshuab hluav taws xob hluav taws xob tau tsim thiab cov tawv npib tsib xee hlau tau dhau los ua cov hlau nplaum sib nqus thiab tau txais kev nyiam rau ib leeg, ua tiav qhov Circuit Court. Thaum cov hlau nplaum raug tshem tawm qhov hloov rov qab mus rau nws lub xeev qhib.

Txij li kev sib cuag ntawm Reed Hloov tau raug kaw los ntawm huab cua, lawv tau tiv thaiv tiv thaiv huab cua hauv ntiaj teb. Kev sib tsoo hermetic ntawm tus ntoo thuv hloov ua rau lawv haum rau siv hauv cov huab cua tawg qhov twg qhov tawg me me los ntawm cov pa hloov pauv yuav ua rau muaj kev phom sij. Reed Hloov muaj qhov tiv taus tsawg heev thaum kaw, feem ntau qis li 50 milliohms li no Reed Hloov tuaj yeem hais kom xav tau xoom lub zog los ua haujlwm nws.

Kauj ruam 2: Cheebtsam

Rau qhov kev qhia no peb xav tau:

- Reed Hloov

-220Ω Resistor

-100Ω Resistor

- LED teeb

- Ntau 'meter'

- Roj teeb

- Cov qhob cij

- Arduino Nano

- Magnets thiab

- Ob peb Txuas Cables

Kauj ruam 3: Demo

Siv ntau lub 'meter' Kuv yuav qhia koj li cas Reed Hloov ua haujlwm. Thaum kuv nqa cov hlau nplaum ze rau ntawm qhov hloov pauv ntau lub ntsuas ntsuas qhia tau hais tias txuas ntxiv mus raws li kev sib chwv sib cuam tshuam ib leeg kom ua tiav qhov Circuit Court. Thaum tshem cov hlau nplaum, qhov hloov pauv rov mus rau nws ib txwm qhib lub xeev.

Kauj Ruam 4: Hom Kev Hloov Reed

Muaj 3 yam yooj yim hom Reed Hloov:

1. Tib Ncej, Ib Leeg Pov, Ib txwm Qhib [SPST-NO] (ib txwm hloov mus)

2. Tib Ncej, Ib Leeg Pov, Ib Feem Kaw [SPST-NC] (ib txwm qhib rau)

3. Tib Ncej, Muab Ob Zaug [SPDT] (ib txhais ceg ib txwm raug kaw thiab ib txwm qhib tuaj yeem siv hloov ntawm ob lub voj voog)

Txawm hais tias feem ntau cov hloov pauv reed muaj ob lub ferromagnetic sib cuag, qee qhov muaj kev sib cuag uas yog ferromagnetic thiab ib qho uas tsis yog sib nqus, thaum qee qhov zoo li thawj Elwood reed hloov tau muaj peb. Lawv kuj sib txawv hauv cov duab thiab qhov ntau thiab tsawg.

Kauj Ruam 5: Txuas Tsis Muaj Arduino

Cia peb sim ntsuas Reed Hloov yam tsis muaj Arduino. Txuas lub LED hauv koob nrog Reed Hloov mus rau lub roj teeb. Thaum cov hlau nplaum raug coj los ze rau ntawm cov neeg sib cuag, lub teeb ci LED thaum lub npib tsib xee-hlau sab hauv lub qhov hluav taws xob nyiam ib leeg, ua kom tiav hauv Circuit Court. Thiab, thaum tshem cov hlau nplaum hloov mus rau nws lub xeev qhib thiab LED tua tawm.

Kauj Ruam 6: Txuas Txuas Reed Hloov mus rau Arduino

Tam sim no, cia txuas Reed Hloov mus rau Arduino. Txuas lub LED mus rau tus pin 12 ntawm Arduino. Tom qab ntawd txuas Reed Hloov mus rau tus lej tus lej 13 thiab tsaws rau lwm qhov kawg. Peb kuj xav tau 100ohm rub-up resistor txuas nrog tib tus pin kom tso cai tswj cov dej ntws tam sim no rau tus lej nkag. Yog tias koj xav tau, koj kuj tseem tuaj yeem siv sab hauv rub tawm tus tiv thaiv ntawm Arduino rau qhov teeb tsa no.

Cov cai yog yooj yim heev. Teeb tus lej tus lej 13 ua Reed_PIN thiab tus lej tus lej 12 ua LED_PIN. Hauv ntu teeb tsa, teeb tsa tus pin-hom ntawm Reed_PIN raws li kev tawm tswv yim thiab LED_PIN raws li tso tawm. Thiab Thaum kawg hauv ntu ntu, qhib lub LED thaum Reed_PIN mus qis.

Zoo ib yam li ua ntej, thaum cov hlau nplaum raug coj los ze rau ntawm cov neeg sib cuag, LED teeb tsa thiab, thaum cov hlau nplaum raug tshem tawm qhov hloov pauv rov qab mus rau nws lub xeev qhib thiab LED tua tawm.

Kauj Ruam 7: Reed Relay

Lwm qhov kev siv dav ntawm Reed Hloov yog hauv kev tsim khoom ntawm Reed Relays.

Hauv Reed Relay qhov chaw sib nqus tau tsim los ntawm cov hluav taws xob tam sim no ntws los ntawm cov kauj ua haujlwm uas haum rau "ib lossis ntau dua" Reed Switchs. Qhov tam sim no ntws hauv lub kauj ua haujlwm Reed Hloov. Cov coils no feem ntau muaj ntau txhiab tus tig ntawm cov hlau zoo heev. Thaum qhov hluav taws xob ua haujlwm tau thov rau cov kauj hlau tau tsim cov hlau nplaum uas tig rau qhov hloov pauv hauv tib txoj kev uas cov hlau nplaum ruaj khov ua.

Kauj ruam 8:

Muab piv rau cov cuab yeej siv hluav taws xob sib txuas, Reed Relays tuaj yeem hloov pauv tau sai dua, vim tias cov khoom txav tau me me thiab hnyav (txawm hais tias hloov bounce tseem muaj nyob). Lawv xav tau lub zog ua haujlwm tsawg dua thiab muaj kev tiv tauj qis dua. Lawv lub peev xwm tuav tam sim no muaj qhov txwv tab sis, nrog cov ntaub ntawv tiv toj tsim nyog, lawv tsim nyog rau "qhuav" hloov daim ntawv thov. Lawv yog cov tshuab yooj yim, muab kev ua haujlwm siab, ua haujlwm tau zoo nrog cov dej ntws me me, ntseeg tau zoo thiab muaj lub neej ntev.

Ntau lab tus reed relays tau siv hauv kev sib tham hauv xov tooj xyoo 1970s thiab 1980s.

Kauj Ruam 9: Cov Ntawv Thov

Tsuas yog txhua qhov chaw koj mus, koj yuav pom Reed Hloov nyob ze uas ntsiag to ua nws txoj haujlwm. Reed cov hloov pauv tau nthuav dav heev uas koj yuav zaum tsis ntau tshaj li ob peb ko taw deb ntawm ib qho ntawm txhua lub sijhawm. Qee qhov ntawm lawv thaj tsam ntawm kev thov yog hauv:

1. Cov tub sab nyiag lub tswb rau lub qhov rooj thiab qhov rais.

2. Reed keyboards tso koj lub laptop kom tsaug zog/hibernation thaum lub hau kaw

3. Cov kua ntsuas qib/ntsuas ntsuas hauv lub tank - lub tshuab nqus dej ntab tau siv los qhib cov hloov pauv tso rau ntawm ntau qib.

4. Kev ntsuas nrawm ntawm lub log tsheb kauj vab/ DC lub tshuab hluav taws xob

5. Nyob rau hauv lub caj npab tig ntawm lub tshuab ntxuav tais diav kom pom thaum lawv jam

6. Lawv khaws koj lub tshuab ntxhua khaub ncaws kom tsis txhob khiav thaum lub hau qhib

7. Hauv kev txiav cov cua sov hauv cov dej tso hluav taws xob, kom tsis txhob tso cua sov rau qhov txaus ntshai.

8. Lawv paub tias lub tsheb puas muaj lub cev nres dej txaus thiab seb puas yog koj lub rooj zaum raug kaw.

9. Anemometers nrog lub khob tig tau reed hloov pauv sab hauv uas ntsuas qhov nrawm ntawm cua.

10. Lawv kuj tseem siv rau hauv cov ntawv thov uas ua rau siv lawv qhov tsis tshua muaj qhov xau tam sim no.

11. Cov twj siv qub, hauv tsheb, cov tshuab tsim khoom, Khoom siv hauv tsev, kev sib txuas lus, khoom siv kho mob, Xov tooj Clamshell thiab ntau ntxiv ……

Nyob rau sab relays lawv tau siv rau kev txiav ua ntu ntu.

Kauj ruam 10: Lub neej

Cov lus tsa suab ntawm cov ntoo tau qis dua qhov qaug zog txwv ntawm cov ntaub ntawv, yog li cov paj ntoo tsis tawg vim qaug zog. Hnav thiab lub neej yuav luag tag nrho nyob ntawm qhov hluav taws xob thauj khoom cuam tshuam rau cov neeg sib cuag nrog rau cov khoom siv ntawm lub reed hloov. Kev sib cuag saum npoo tsuas yog tshwm sim thaum qhov kev sib txuas sib txuas qhib lossis kaw. Vim li no, cov tuam txhab tsim khoom lub neej nyob rau hauv cov lej ntawm kev ua haujlwm ntau dua li teev lossis xyoo. Feem ntau, cov hluav taws xob ntau dua thiab cov dej ntws siab dua ua rau hnav tau sai thiab lub neej luv.

Lub hnab ntawv iav txuas ntxiv lawv lub neej thiab tuaj yeem raug puas ntsoog yog tias lub reed hloov tau raug rau cov neeg kho tshuab kev nyuaj siab. Lawv pheej yig, lawv nyob ruaj khov, thiab hauv daim ntawv thov qis-tam sim no, nyob ntawm cov khoom siv hluav taws xob, lawv tuaj yeem nyob ntev txog li ib txhiab daus las.
