Xa idatha yokulinganisa ye-ultrasonic flowmeter ingafakwanga kwinkqubo yolawulo ephakathi, ingxaki inokwenzeka kwintambo yoqhagamshelo. Ukusombulula iingxaki kungenziwa kwezi nkalo zi-4 zilandelayo:
Inyathelo 1: Jonga uqhagamshelo lwentambo yonxibelelwano. Okokuqala, qinisekisa ukuba intambo yonxibelelwano (njengemigca ye-RS485 kunye neentambo zenethiwekhi) phakathi kwe-flowmeter kunye nenkqubo yolawulo ephakathi ixhunyiwe kakuhle, kwaye nokuba ii-interfaces zikhululekile okanye zi-oxidized. Ukuba unxibelelwano lwe-RS485 lusetyenziswa, jonga ukuba imigca ye-A kunye ne-B iqhagamshelwe ngasemva. Uqhagamshelo olubuyela umva luya kubangela ukungaphumeleli kokudluliselwa kwedatha, ngoko ke intambo kufuneka iqhagamshelwe ngokulandelelana ngokuchanekileyo; ukuba unxibelelwano lwe-Ethernet lusetyenziswa, jonga ukuba intambo yenethiwekhi ayisebenzi, enokuvavanywa ngokutshintsha intambo yenethiwekhi. Kwangaxeshanye, qinisekisa ukuba izixhobo zenethiwekhi ezifana neeswitshi kunye nee-routers zisebenza ngokuqhelekileyo na kwaye nokuba kukho ukusilela kombane okanye ukuqhawuka kwenethiwekhi.
Inyathelo lesi-2: Qinisekisa ukuba useto lweparameter yonxibelelwano luyahambelana. Ngenisa ujongano "lwezicwangciso zonxibelelwano" lwe-flowmeter, jonga iiparameter ezifana ne-baud rate, i-parity, ii-data bits kunye nee-stop bits, kwaye uqinisekise ukuba zihambelana ngokupheleleyo neeparameter zonxibelelwano zenkqubo yolawulo oluphakathi. Umzekelo, ukuba i-flowmeter baud rate isetelwe kwi-9600 kwaye inkqubo yolawulo oluphakathi isetelwe kwi-4800, ukuhanjiswa kwedatha okungaqhelekanga kuya kwenzeka, kwaye iiparameter zazo zombini kufuneka zilungiswe kwixabiso elifanayo. Kwangaxeshanye, jonga ukuba idilesi yesixhobo (efana nedilesi yesigqila) ye-flowmeter ingaphakathi koluhlu lokuqondwa kwenkqubo yolawulo oluphakathi ukuze kuthintelwe ingxabano yedilesi okanye ukuba ingaphandle koluhlu.
Inyathelo lesi-3: Xazulula iingxaki ze-firewall kunye nezicwangciso zesoftware. Ukuba inkqubo yolawulo oluphakathi isebenzisa isoftware yekhompyutha ukufumana idatha, jonga ukuba i-firewall yekhompyutha iyayivala na i-port yonxibelelwano ye-flowmeter. I-firewall ingacinywa okwethutyana ukuze kuvavanywe. Ukuba idatha ingalayishwa ngokuqhelekileyo, umthetho wemvume wale port kufuneka wongezwe kwi-firewall. Kwangaxeshanye, jonga ukuba isoftware yolawulo oluphakathi ikhethe na i-protocol yonxibelelwano echanekileyo (efana ne-Modbus RTU, i-Modbus TCP). Ii-protocols ezingahambelaniyo ziya kubangela ukungaphumeleli kokuhlaziya idatha, ngoko ke i-protocol ehambelana ne-flowmeter kufuneka ikhethwe kwakhona.
Inyathelo lesi-4: Vavanya unxibelelwano oluzimeleyo lwesixhobo. Ukuba la manyathelo angasentla aqhelekile, i-flowmeter inokuqhagamshelwa ngqo kwikhompyutha (ngaphandle kokudlula kwinkqubo yolawulo oluphakathi), kwaye isoftware yovavanyo exhasayo yesixhobo ingasetyenziselwa ukuthumela idatha ukujonga ukuba ikhompyutha ingayifumana na. Ukuba ingafunyanwa, oko kubonisa ukuba akukho ngxaki nge-flowmeter ngokwayo, kwaye impazamo isenokuba kwi-hardware okanye kwisoftware yenkqubo yolawulo oluphakathi, ngoko ke imodyuli yonxibelelwano kunye nesoftware yokufumana idatha yenkqubo yolawulo oluphakathi kufuneka ilungiswe; ukuba ayinakufunyanwa, imodyuli yonxibelelwano ye-flowmeter ingonakala, kwaye kuyimfuneko ukuqhagamshelana nomenzi ukuze kugcinwe okanye kutshintshwe imodyuli.
