Dab tsi yog ibelectronically tswj industrial joystick? Lub tshuab hluav taws xob tswj kev lag luam joystick yog tib neeg-khoos phis tawj sib cuam tshuam cov cuab yeej siv nyob rau hauv ntau yam khoom siv hluav taws xob kom paub qhov kev txiav txim ntawm tes ntawm tus kov los ntawm lub potentiometer lossis Hall sensor, thiab xa tawm cov teeb liab hluav taws xob sib txuas los tswj cov kev taw qhia, ceev, thiab kev ncua deb ntawm tus ntaus ntawv. Ua ntej qhov tshwm sim ntawm electronically controlled industrial joysticks, muaj ob hom joysticks hauv keeb kwm. Xyoo 1835, Asmeskas Otis tau tsim thiab tsim thawj lub thoob excavator uas tau tsav los ntawm lub tshuab hluav taws xob. Tus neeg teb xov tooj thawb lub zog ua haujlwm los tswj lub excavator los ntawm lub zog, levers, siv thiab traction ropes. Qhov kev khiav hauj lwm lever no yog ib tug phau ntawv khiav hauj lwm lever, uas yog tseem siv rau tej yam yooj yim mechanical khoom. Nws qhov zoo yog tus nqi qis thiab kev saib xyuas yooj yim. Txawm li cas los xij, nrog rau kev txhim kho ntxiv ntawm cov tshuab thiab ntau thiab ntau lub zog, cov qauv ntawm lub tshuab ua haujlwm nkaus xwb ntawm kev siv lub zog tseem ua ntau dua, thiab maj mam ua tsis tau raws li qhov xav tau.
Nyob rau xyoo 1940, mounted excavators tshwm sim nrog hydraulic backhoes ntawm cov tsheb laij teb, uas tau tsav los ntawm kev ua haujlwm hydraulic. Lub zog hydraulic ua haujlwm txuas ncaj qha rau hydraulic valve los tswj nws qhov qhib (kaw), thiab lub zog hydraulic hloov mus rau hauv lub zog siv hluav taws xob los tswj cov tshuab, uas yog siv ntau lub tsheb engineering.
Txoj kev loj hlob ntawm hydraulic kev khiav hauj lwm lever muaj keeb kwm ntawm ntau tshaj 80 xyoo, cov khoom yog mature, thiab tag nrho cov seem tau standardized thiab serialized. Piv nrog rau phau ntawv khiav hauj lwm lever nrog complex thiab loj qauv, nws yog me me nyob rau hauv loj thiab lub teeb nyob rau hauv qhov hnyav, uas muaj peev xwm paub qhov loj-scale stepless ceev kev cai, ruaj khov kis tau tus mob, muaj zog tiv thaiv kev cuam tshuam muaj peev xwm thiab zoo low-speed kev kawm. Txawm li cas los xij, sib raug zoo, lub zog ua haujlwm hydraulic muaj qhov ua haujlwm qis, kev tsim hluav taws xob siab, tsis tuaj yeem tau txais qhov kev sib txuas ruaj khov, thiab muaj qhov tsis txaus ntseeg ntawm kev xau, thiab cov roj hydraulic sab hauv yog nplaim taws thiab tawg, uas yog qhov sib txawv ntawm qhov kev thov kom muaj kev nyab xeeb. thiab kev tiv thaiv ib puag ncig. Yog li ntawd, nrog kev txhim kho thev naus laus zis, lub zog ua haujlwm hydraulic kuj tau pib maj mam hloov los ntawm lwm lub zog ua haujlwm, uas yog, hluav taws xob tswj kev lag luam qib.
Electronically tswj kev lag luam joysticks yog thawj zaug siv los tswj cov khoom siv loj thiab qib siab xws li dav hlau thiab nkoj. Hauv xyoo 1960, lub dav hlau ua haujlwm platform tau tawm hauv Tebchaws Meskas. Vim tias qhov kev ncua deb ntawm lub platform tswj thiab tus neeg tsav tsheb ntawm lub dav hlau ua haujlwm platform (txog 50-60} meters) yog qhov loj dua li ntawm cov tshuab siv dav siv, lub zog ua haujlwm hydraulic tsis tuaj yeem tso tawm qhov kev tswj kom du, yog li Kev ua haujlwm ntawm huab cua. platform txais cov tshuab electromechanical-hydraulic kev koom ua ke, thiab siv cov hluav taws xob tswj qib hauv kev tswj hwm. Los ntawm 1985, thiaj li yuav txuag tau lub zog, ntau excavator manufacturers pib siv electromechanical-hydraulic integrated tswj systems rau loj-tsim excavation.
Nrog rau qhov nrov ntawm digitalization thiab cov kev xav tau siab dua rau kev tiv thaiv ib puag ncig, ntau thiab ntau lub tshuab tsim kho kuj tau pib Siv lub tshuab hluav taws xob tswj kev lag luam joystick. Piv nrog rau kev ua haujlwm hydraulic, lub zog tswj hluav taws xob tuaj yeem teeb tsa qhov kev nyab xeeb, paub txog kev tswj chaw taws teeb ntev thiab kev tswj xyuas tas li, tsis tshua muaj kev xav tau rau cov neeg ua haujlwm, kev tswj xyuas siab, siab teb ceev, kev sib raug zoo ntawm cov tswv yim thiab cov zis, thiab tuaj yeem ua tau. tso zis raws li tus neeg yuav tsum tau muaj. Voltage, tam sim no lossis digital cov cim qhia tau yooj yim dua los siv rau kev ua haujlwm ntse. Nyob rau tib lub sijhawm, nrog kev txhim kho ntawm cov cuab yeej siv hluav taws xob thiab kev tsim qauv, lub zog tswj hluav taws xob tuaj yeem tshem tawm qhov cuam tshuam ntawm qhov kub thiab txias thiab electromagnetic cuam tshuam ntawm cov teeb liab tso tawm, thiab hluav taws xob tswj tuav yuav muaj tseeb ci hauv ntau qhov chaw.
