Lub reed hloov yog ib qho hluav taws xob relay ua los ntawm kev siv magnetic teb. Txawm hais tias nws tsuas yog zoo li ib daim iav nrog cov hlau lead tawm los ntawm nws, nws yog ib qho kev tsim khoom siv zog uas ua haujlwm zoo nrog txoj hauv kev kho kom haum rau lawv siv hauv ntau daim ntawv thov. Yuav luag tag nrho cov reed keyboards ua hauj lwm nyob rau hauv lub hauv paus ntawm ib tug txaus nyiam quab yuam: ib tug opposite polarity tsim nyob rau hauv ib txwm qhib kev sib cuag. Thaum cov hlau nplaum txaus, qhov kev quab yuam no kov yeej qhov tawv ntawm cov reed hniav, thiab kev sib cuag rub tawm ua ke.
Lub tswv yim no yog Ameslikas tsim nyob rau hauv 1922 los ntawm Lavxias teb sab xib fwb, V. Kovalenkov. Txawm li cas los xij, qhov hloov pauv tau patented hauv xyoo 1936 los ntawm WB Ellwood ntawm Bell Telephone Laboratories hauv Asmeskas. Thawj qhov ntau lawm "Reed Switches" ntaus lub lag luam nyob rau hauv 1940 thiab nyob rau hauv lub lig 1950s, lub creation ntawm quasi-electronic exchanges nrog ib tug hais lus channel raws li reed hloov technology twb launched. Xyoo 1963 Lub Tuam Txhab Tswb tau tso tawm nws tus kheej version - ESS-1 hom tsim los rau kev sib pauv hloov pauv. Los ntawm 1977, txog 1,000 hluav taws xob sib pauv ntawm hom no tau ua haujlwm thoob plaws hauv Tebchaws Meskas Niaj hnub no, reed hloov tshuab siv rau hauv txhua yam los ntawm aeronautical sensors mus rau tsis siv neeg txee teeb pom kev zoo.
Los ntawm kev tswj hwm kev lag luam, txhua txoj hauv kev mus rau cov neeg nyob ze Mike tsuas yog xav kom muaj teeb pom kev nyab xeeb thaum hmo ntuj los qhia nws thaum ib tus neeg nyob ze rau tsev, muaj ntau txoj hauv kev los siv cov keyboards thiab sensors no. Txhua yam uas xav tau yog lub txim ntawm ingenuity kom nkag siab tias feem ntau cov haujlwm niaj hnub tuaj yeem ua tau zoo dua nrog kev hloov pauv lossis ntsuas cov cuab yeej.
Cov cwj pwm tshwj xeeb ntawm lub reed hloov ua rau lawv ib qho kev daws teeb meem tshwj xeeb rau kev sib tw. Vim tias tsis muaj kev siv tshuab, kev ua haujlwm nrawm dua thiab ua haujlwm tau zoo. Lawv lub peev xwm rhiab heev tso cai rau reed hloov sensors yuav tsum tau embedded sib sib zog nqus nyob rau hauv lub rooj sib txoos thaum tseem tab tom qhib los ntawm ib tug discreet hlau nplaum. Tsis muaj qhov yuav tsum tau muaj qhov hluav taws xob vim nws yog magnetic activated. Ntxiv mus, cov cwj pwm ua haujlwm ntawm reed keyboards ua rau lawv zoo tagnrho rau cov huab cua nyuaj, xws li kev poob siab thiab kev vibration ib puag ncig. Cov cwj pwm no suav nrog kev ua kom tsis muaj kev sib cuag, sib txuas nrog hermetically kaw, yooj yim circuitry, thiab tias cov hlau nplaum ua kom muaj zog txav mus los ntawm cov khoom tsis yog ferrous. Cov txiaj ntsig no ua rau reed keyboards zoo meej rau kev siv qias neeg thiab nyuaj. Qhov no suav nrog kev siv hauv aerospace sensors thiab kev kho mob sensors uas xav tau kev siv tshuab siab heev.
Nyob rau hauv 2014, HSI Sensing tau tsim thawj reed hloov tshuab tshiab nyob rau hauv ntau tshaj 50 xyoo: ib tug tseeb daim ntawv B hloov. Nws tsis yog hloov kho SPDT daim ntawv C hloov, thiab nws tsis yog qhov sib nqus sib nqus SPST daim ntawv A hloov. Los ntawm qhov kawg-rau-kawg engineering, nws muaj qhov tshwj xeeb tsim cov nplooj reed uas ingeniously tsim ib tug zoo li polarity nyob rau hauv lub xub ntiag ntawm ib tug externally siv magnetic teb. Thaum lub magnetic teb muaj zog txaus lub repelling quab yuam tsim nyob rau hauv kev sib cuag cheeb tsam thawb ob tug reed tswvcuab deb ntawm ib leeg, yog li rhuav kev sib cuag. Nrog rau kev tshem tawm ntawm cov magnetic teb, lawv cov neeg kho tshuab tsis ncaj ncees lawm rov qab qhov qub kaw. Nov yog thawj qhov kev tsim kho tshiab tiag tiag hauv reed hloov tshuab hauv xyoo caum!
Txog niaj hnub no, HSI Sensing tseem yog cov kws tshaj lij kev lag luam hauv kev daws teeb meem rau cov neeg siv khoom hauv kev sib tw reed hloov tsim daim ntawv thov. HSI Sensing tseem muab cov kev daws teeb meem raug rau cov neeg siv khoom uas xav tau zoo ib yam, tsis sib xws.
