Raws li ib feem inseparable ntawm kev tswj system ntawm kev tsim kho machinery thiab ib tug indispensable ib feem ntawm tib neeg-tshuab interface,industrial tuavTam sim no tau dav siv nyob rau hauv ntau lub teb thiab ceg ntawm domestic siv machinery, ua liaj ua teb machinery, aerial ua hauj lwm platforms, thiab lwm yam.
Tam sim no, nyob rau hauv kev lag luam siv, raws li kev faib loj ntawm cov ntaub ntawv tswj, muaj roughly peb hom kev lag luam joysticks: 1. Mechanical joystick; 2. Hydrauli joystick; 3. Hluav taws xob tswj joystick.
Ntawm lawv, nyob rau hauv feem ntau industries, mechanical handles tau maj mam tshem tawm nyob rau hauv tus txheej txheem ntawm kev tsim kho tshiab nyob rau hauv kuv lub teb chaws vim lawv tsis muaj peev xwm ua kom tiav complex analogues thiab logic tswj, thiab tsuas yog siv nyob rau hauv qee lub sij hawm luv nqi nrog cov nqi siab.
Lub hydraulic kov, los yog kev lag luam sib sau ua ke hu ua hydraulic pilot kov, yog tam sim no daim ntawv thov tseem ceeb hauv kev ua lag luam. Nws qhov zoo dua yog tias nws tuaj yeem siv cov nqi qis los tswj cov dej ntws ntawm hydraulic pilot valve thiab koom tes nrog cov maub los rau kev tswj cov logic yooj yim. Tsis tas li ntawd, tus tsav vim hais tias tus kov tsis cuam tshuam nrog kev ua haujlwm ntawm hluav taws xob thiab lwm yam tsis zoo, nws cov kev saib xyuas thiab kev hloov pauv kuj yooj yim dua, tab sis kuj tseem muaj qee lub sijhawm uas cov hydraulic kov tsis tuaj yeem zam cov roj to, thiab nws tsis tuaj yeem siv rau qee lub sijhawm nrog siab dua. kev khiav hauj lwm ib puag ncig xav tau.
Thaum kawg, muaj lub tshuab hluav taws xob tswj tuav, uas muaj cov teeb liab hluav taws xob ruaj khov, muaj zog kho tau, thiab tuaj yeem ua haujlwm yooj yim logic. Txoj kev nyiam ntawm qhov system hloov mus rau qhov kev tswj hwm hluav taws xob. Qhov kom zoo dua ntawm kev tswj hluav taws xob yog tias nws tuaj yeem ua ntau txoj hauv kev logic thiab kev nyab xeeb. Nws tau siv rau ntau xyoo hauv kev lag luam dav hlau ua haujlwm nrog kev nyab xeeb siab. Thiab cov khoom siv hluav taws xob tswj tau siv tau rau hauv ntau qhov kev lag luam uas xav tau kev ua kom huv ib puag ncig zoo, xws li cov khw muag khoom loj, kev soj ntsuam video, kev kho mob, thiab lwm yam.
Feem ntau hais lus, txoj kev ua haujlwm yog txiav txim siab raws li kev ua haujlwm thiab kev ua haujlwm. Ntawm lwm qhov teeb meem xaiv, cov lus nug tshaj plaws yog kev xaiv Hall hom thiab potentiometer hom.
Hall hom yog tus cwj pwm los ntawm kev ua haujlwm, tsis muaj kev sib cuag, thiab lub neej yuav ua tau ntev dua. Feem ntau hom potentiometer muaj lub neej ntev ntawm 1 lab lub sij hawm mus rau 2 lab lub sij hawm, thiab hom tsev tuaj yeem ua tiav 5 lab zaug lossis ntau dua; tab sis nws xav tau lub zog hluav taws xob los ua kom tiav cov txiaj ntsig analog, thiab cov cuab yeej siv hauv tsev tsis tuaj yeem siv rau hauv ib puag ncig kev ua qias tuaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov plua plav hlau ntau lossis muaj zog sab nraud magnetic teb, qhov kev hloov ntawm magnetic teb yuav ua rau. qhov tso zis ntawm tus kov hloov los yog txawm poob.
Hom potentiometer yog tus cwj pwm los ntawm passive, tiv tauj hom kev ua haujlwm, thiab nws qhov kev ruaj ntseg txheeb ze rau Hall yuav zoo dua. Feem ntau hais lus, lub neej ntawm potentiometer muaj feem xyuam nrog lub neej ntawm potentiometer nws tus kheej. Feem ntau cov khoom siv hluav taws xob zoo hauv tsev muaj lub neej ntev ntawm ntau pua txhiab mus rau tsheej lab ntawm lub sijhawm, thiab qee cov potentiometers tuaj yeem ncav cuag 1 lab txog 2 lab lub sijhawm lossis ntau dua. siab. Thaum siv hom potentiometer, tsis tas yuav tsum muaj lub zog ntxiv.
Raws li cov yam ntxwv saum toj no, cov khoom siv hluav taws xob tswj feem ntau yog siv rau excavators, loaders thiab lwm yam kev siv ntau zaus yog feem ntau ntawm Hall hom. Nws yog siv rau mining machinery thiab lwm yam xwm txheej uas tej zaum yuav muaj hlau plua plav lossis electromagnetic cuam tshuam. Nws raug nquahu kom siv potentiometer. Hom hluav taws xob tswj tuav. Tsis tas li ntawd, nws kuj tau txiav txim siab raws li seb puas muaj lub zog ntxiv rau ntawm tus neeg siv khoom sab. Feem ntau, cov pa hluav taws xob ntawm Hall yog 3.3Vdc thiab 5Vdc, thiab qhov dav voltage version tuaj yeem siv tau los ntawm 9 ~ 36Vdc.
Tsis tas li ntawd, muaj ib daim ntawv tso cai tsheb npav, uas feem ntau yog siv rau lub sijhawm uas yuav tsum muaj kev sib txuas lus hauv tsheb npav. Feem ntau, kev tsim kho tshuab kev lag luam siv ntau hom tsheb npav CAN. Lwm qhov kev lag luam kuj tseem siv RS232, RS485, USB thiab lwm daim ntawv tso tawm tsheb npav. Cov neeg siv khoom yuav tsum xaiv raws li lawv tus kheej ua haujlwm.
Thaum kawg, muaj cov ntawv thov ntawm lub caij nplooj ntoos hlav rov qab hom thiab kev sib txhuam txoj hauj lwm hom:
1. Caij nplooj ntoos hlav rov qab hom: thaum lub sij hawm ua hauj lwm zaus yog siab thiab nws yuav tsum tau rov qab mus rau qhov nruab nrab los yog pib txoj hauj lwm. Feem ntau, kev tsim kho tshuab, tsheb ua haujlwm dav hlau, forklifts thiab lwm lub sijhawm yuav tsum tau ua haujlwm tsis tu ncua lossis rov pib ua haujlwm.
1. Kev sib txhuam txoj hauj lwm hom: lub sij hawm uas lub sij hawm ua hauj lwm zaus yog tsawg thiab nws yog tsim nyog rau kev khiav hauj lwm mus rau lub positioning txoj hauj lwm. Nws feem ntau yog siv rau kev ua liaj ua teb machinery, drilling rigs, mining thiab lwm yam machinery uas yuav tsum tau ua kom lub zog khiav hauj lwm tsis tu ncua.
