Nrog rau kev txhim kho thev naus laus zis, kev tsim cov khoom siv dej tsis sib haum tau dhau los ua me, thiab lub hom phiaj ntawm miniaturization yog nyob hauv qhov chaw tsawg dua. Ntawm chav kawm, cov neeg siv yuav tsum tau tso cai rau nruab intensive, thiab intensive installation muaj teeb meem thaum tshav kub kub dissipation, yog li ntawd lub sab hauv lub hwj chim noj yuav tsum tau txo. Yog li ntawd, tus nqi ntawm kev siv hluav taws xob sab hauv yuav tsum tau them nyiaj rau thaum xaiv.
Niaj hnub no, muaj ntau qhov sib cais terminals nrog CPU ua lub hauv paus ntawm kev ua lag luam, uas muaj kev hloov kho ntawm qhov chaw thiab kev sib txuas lus, thiab muaj kev hloov pauv siab. Rau cov neeg siv khoom, nws tuaj yeem txo cov khoom muag kom muaj nuj nqis thiab txo cov nyiaj rov qab. Lub davhlau ya nyob twg cais nrog CPU raws li cov tub ntxhais yuav muaj tseeb dhau los ua qhov tseem ceeb hauv daim teb no.
Sanmenwan ntseeg tias muaj lwm txoj hauv kev los cais cov khoom xa tawm. Lub sensor thiab transmitter yog kev koom ua ke thiab yuav tsum tau muab tso rau hauv ib qho chaw nyob rau ntawm qhov chaw. Nyob rau lub sijhawm no, lub davhlau ya nyob twg cais feem ntau yog muab tso rau hauv lub txee ntawm lub hauv paus tswj chav, thiab lub davhlau ya nyob twg nyob rau hauv lub txee faib cov khoom siv hluav taws xob rau lub tshuab xa hluav taws xob. Qhov twg siv yog nyob ntawm PLC interface.
Kev debugging ntawm qhov chaw yuav ua rau muaj kev tsis sib haum xeeb ntawm qhov ntsuas thiab PLC interface. Cov khoom xa tawm yog plaub-xaim transmitter outputting 4-20mA, thiab qhov kawg tau txais 4-20mA interface yog ob-xaim voj fais fab mov hom. Kev sib txuas ncaj qha yuav ua rau muaj kev tsis sib haum xeeb ntawm lub zog. Txoj kev daws teeb meem yog siv cov terminals cais kom tau txais thiab cais 4-20mA ntawm qhov chaw, thiab nruab ib lub voj voog nyob rau hauv cov khoom tso tawm sab hauv ntawm cov terminals cais kom phim ob-xaim voj fais fab interface hom ntawm PLC.
