Izixhobo zemizi-mveliso ziye zahambela phambili kakhulu kule minyaka imbalwa idlulileyo, xa uninzi lwezixhobo bezithintelwe kwi-4-20 okanye i-0-20mA yemveliso ye-analog ngokomlinganiselo wokuguquguquka kwenkqubo.Inkqubo eguquguqukayo iguqulelwe kwisignali ye-analog enikezelweyo edluliselwe kwisixhobo phezu kwe-2-intambo ukuya kwisalathisi okanye inkqubo yokulawula, kunye ne-multi-drop configuration, efuna ukufikelela ngokuthe ngqo ukulungiswa kwezandla ngabasebenzi bokulondoloza.
Iinzuzo ezinokuthi zibe kho zeteknoloji yedijithali kwisixhobo ziye zaqatshelwa emva koko.Kunokubakho ubutyebi bedatha exabisekileyo kunye nemisebenzi equlethwe kwisixhobo, njengokucwangciswa kwesixhobo, imida ye-alamu, ixesha lokusebenza kunye neemeko, ulwazi lokuxilonga, njl.Iprotocol ye-HARTyavela njengenye yeendlela zokuqala zokufikelela kule datha inemitya ukwenza izixhobo zibe krelekrele.
Itekhnoloji ye-HART ivumela unxibelelwano kunye nesixhobo se-analog usebenzisa isignali yonxibelelwano yedijithali ehanjiswe phezu kwe-2-wire efanayo njengemveliso ye-analog.Lo mqondiso wedijithali unikeze unxibelelwano lwe-2 phakathi kwesixhobo kunye nomninimzi ngaphandle kokuphazamisa umphumo, ukuququzelela ukufikelela kwiinqununu ezahlukeneyo zedatha.Nge-HART, abasebenzi banokunxibelelana nomthumeli kwaye benze uqwalaselo okanye ukuxilongwa ngelixa lenza umlinganiselo wenkqubo yexesha langempela.
WangYuan WP421A Ubushushu obuphezulu Transmitter nge 4~20mA + HART Protocol isiphumo
Ngaxeshanye, uphuhliso lobunye ubuchwephesha bedijithali kwakhona beluqhutywa obuya kusasazwa koohola bendlela abazinikeleyo bonxibelelwano, nganye ibonelela ngeenzuzo ezithile, kubandakanywa nommeli weteknoloji yeFieldbus.Iprotocol yeModbus ene-RS-485 interface.I-Modbus yi-serial master-slave open protocol, evumela nawuphi na umenzi ukuba adibanise iprotocol kwisixhobo, ukubonelela ngokufikelela kwendawo kwizixhobo ezihlakaniphile ezivela kwiinkqubo zokusingatha.

Enkosi kwinkqubela phambili yetekhnoloji kwisiqingatha senkulungwane edlulileyo, ukuhanjiswa kwesixhobo kuye kwavela kuphela kwinkqubo esisiseko eguquguqukayo ukuya kubutyebi bolwazi olukhoyo oluya kufikelela kwinqanaba leshishini.Kwixesha elizayo, itekhnoloji yedijithali iya kuqhubeka nokubonelela ngeenkcukacha ezithe kratya ezivela kubathumeli, ngoluhlu olubanzi lweendlela zokufikelela.
E-WangYuan, umenzi waseTshayina onamava angaphezulu kweminyaka engama-20 kwinkalo yezixhobo, sibeka phambili ukusetyenziswa kweziphumo zonxibelelwano oluhlakaniphile kwiimveliso zesixhobo sokulinganisa.Uninzi lweemveliso zethu zokulinganisa uxinzelelo, inqanaba, ubushushu kunye nokuhamba kwamkelekile ukulungelelanisa kwimveliso yesignali kubandakanya iProtocol ebhalisiweyo ye-HART kunye ne-RS-485 Modbus ukuhlangabezana neemfuno zabasebenzisi kunye nemeko yentsimi.
