Amathuluzi embonini athuthuke kakhulu emashumini ambalwa eminyaka adlule, lapho iningi lamathuluzi lalikhawulelwe kokuphumayo okulula okungu-4-20 noma 0-20mA ngokulingana nokuhlukahluka kwenqubo.Inqubo eguquguqukayo iguqulelwe kusignali ye-analogi ezinikele edluliswa kusukela ensimbini ngentambo engu-2 ukuya kunkomba noma isistimu yokulawula, enokulungiselelwa kokudedela okuningi, okudinga ukufinyelela okuqondile kokulungiswa mathupha ngabasebenzi bokunakekela.
Izinzuzo ezingaba khona zobuchwepheshe bedijithali ekufakweni kwezinsimbi ziye zabonwa kamuva.Kungase kube nedatha eningi ebalulekile nemisebenzi equkethwe ethuluzini, njengokucushwa kwedivayisi, imikhawulo ye-alamu, isikhathi sokusebenza nezimo, ulwazi lokuxilonga, njll. Ukuthola idatha enjalo kusiza ukuthuthukisa ukusebenza kwedivayisi, futhi ekugcineni kuthuthukisa ukusebenza kwenqubo.Iphrothokholi ye-HARTkuvele njengenye yezindlela zakuqala zokufinyelela le datha enamathele ukwenza amathuluzi ahlakaniphe.
Ubuchwepheshe be-HART buvumela ukuxhumana nethuluzi le-analog kusetshenziswa isignali yokuxhumana yedijithali edluliswa phezu kwentambo engu-2 efanayo nokuphumayo kwe-analog.Lesi siginali yedijithali inikeze ukuxhumana kwezindlela ezi-2 phakathi kwethuluzi nomsingathi ngaphandle kokuphazamisa okukhiphayo, kwenze kube lula ukufinyelela kuzingxenye ezihlukahlukene zedatha.Nge-HART, abasebenzi bangakwazi ukuxhumana nesidluliseli futhi benze ukumisa noma ukuxilonga ngenkathi senza ukulinganisa kwenqubo yesikhathi sangempela.

Ngesikhathi esifanayo, ukuthuthukiswa kobunye ubuchwepheshe bedijithali nakho kwakuqhubeka okwakuzosakazwa emigwaqweni emikhulu yezokuxhumana ezinikele, ngamunye unikeza izinzuzo ezithile, okuhlanganisa nobuchwepheshe obumele i-Fieldbus.Iphrothokholi ye-Modbus ene-RS-485 interface.I-Modbus iyiphrothokholi evulekile ye-serial master-slave, evumela noma yimuphi umenzi ukuthi ahlanganise iphrothokholi ibe yithuluzi, ukuze anikeze ukufinyelela kwasendaweni kumathuluzi ahlakaniphile avela kumasistimu okusingatha.

Ngenxa yentuthuko yezobuchwepheshe kule ngxenye yekhulu leminyaka edlule, ukudluliswa kwamathuluzi kuye kwashintsha kusukela ekuguquguqukeni okuyinhloko kuya engcebweni yolwazi olutholakalayo olufinyelela ezingeni lebhizinisi.Ngokuzayo, ubuchwepheshe bedijithali buzoqhubeka nokuhlinzeka ngemininingwane eminingi evela kubathumeli, ngobubanzi obubanzi bezindlela zokufinyelela.
Kwa-WangYuan, umkhiqizi waseShayina onolwazi olunzulu lweminyaka engaphezu kwengu-20 emkhakheni wezinsimbi, sibeka phambili ukusetshenziswa kwemiphumela yokuxhumana ehlakaniphile emikhiqizweni yensimbi yokulinganisa.Iningi lemikhiqizo yethu yokulinganisa ingcindezi, ileveli, izinga lokushisa nokugeleza yamukela ukwenziwa ngendlela oyifisayo ekuphumeni kwesignali okuhlanganisa nesisekelo esibhalisiwe se-HART Protocol kanye ne-RS-485 Modbus ukuze ihlangabezane nezimfuno zabasebenzisi nesimo senkundla.
