Uphuhliso loNxibelelwano oluLungileyo kwiiTransmitters

Izixhobo zoshishino ziye zaphucuka kakhulu kwiminyaka embalwa edlulileyo, xa uninzi lwezixhobo lwalulinganiselwe kwi-4-20mA elula okanye i-0-20mA analog output ngokulingana ne-process variable. I-process variable iguqulwe yaba yisignali ye-analog ezinikeleyo edluliselwe kwisixhobo nge-2-wire ukuya kwi-indicator okanye inkqubo yolawulo, enoqwalaselo lwe-multi-drop, olufuna ukufikelela ngqo kulungiso lwesandla ngabasebenzi bokulungisa.

Iingenelo ezinokubakho zobuchwepheshe bedijithali kwizixhobo ziye zaqatshelwa emva koko. Kunokubakho ubutyebi bedatha exabisekileyo kunye nemisebenzi equlethwe kwisixhobo, njengoqwalaselo lwesixhobo, imida ye-alamu, ixesha lokusebenza kunye neemeko, ulwazi lokuxilonga, njl. Ukufumana idatha enjalo kunceda ukuphucula ukusebenza kwesixhobo, kwaye ekugqibeleni kuphucule ukusebenza kwenkqubo.Iprotokholi ye-HARTyavela njengenye yeendlela zokuqala zokufikelela kule datha ilahlekileyo ukuze izixhobo zibe krelekrele.

Itekhnoloji ye-HART ivumela unxibelelwano ngesixhobo se-analog sisebenzisa isignali yonxibelelwano yedijithali edluliselwa kwiingcingo ezimbini ezifanayo nesiphumo se-analog. Esi signali yedijithali ibonelela ngonxibelelwano oluziindlela ezimbini phakathi kwesixhobo kunye nomsingathi ngaphandle kokuphazamisa imveliso, okwenza kube lula ukufikelela kwiinkcukacha ezahlukeneyo. Nge-HART, abasebenzi banokunxibelelana nomthumeli kwaye benze uqwalaselo okanye uxilongo ngelixa esenza umlinganiselo wenkqubo ngexesha langempela.

Kwangaxeshanye, uphuhliso lwezinye iitekhnoloji zedijithali lwaluqhubeka olwaluza kudluliselwa kwiindlela ezinkulu zonxibelelwano, nganye inika iingenelo ezithile, kuquka netekhnoloji yeFielbus emeleyo.Iprotokholi yeModbus ene-interface ye-RS-485I-Modbus yiprotokholi evulekileyo ye-master-slave serial, evumela nawuphi na umenzi ukuba adibanise le protocol kwisixhobo, ukubonelela ngokufikelela kwasekhaya kwizixhobo ezikrelekrele ezivela kwiinkqubo zomsingathi.

Ngenxa yokuqhubela phambili kwetekhnoloji kwisithuba senkulungwane esingamashumi amahlanu edlulileyo, ukuhanjiswa kwezixhobo kuye kwavela ekubeni yindlela ephambili yokuguquguquka ukuya kubutyebi bolwazi olufumanekayo olufikelela kwinqanaba leshishini. Kwixesha elizayo, itekhnoloji yedijithali iya kuqhubeka nokubonelela ngeenkcukacha ezithe vetshe ezivela kubathumeli, ngeendlela ezahlukeneyo zokufikelela.

Apha eWangYuan, umenzi waseTshayina onamava angaphezu kweminyaka engama-20 kwicandelo lokusebenzisa izixhobo, sibeka phambili ukusetyenziswa kweziphumo zonxibelelwano ezikrelekrele kwiimveliso zezixhobo zokulinganisa. Uninzi lweemveliso zethu zokulinganisa uxinzelelo, inqanaba, ubushushu kunye nokuhamba kwamanzi zamkela ukwenziwa ngokwezifiso kwimveliso yesiginali kuquka iProtocol ye-HART ebhalisiweyo kwisiseko kunye ne-RS-485 Modbus ukuze ihlangabezane neemfuno zabasebenzisi kunye nemeko yentsimi.
