Kusintha kwa Kulankhulana Mwanzeru pa Zotumiza

Zipangizo zamafakitale zapita patsogolo kwambiri m'zaka zingapo zapitazi, pomwe zida zambiri zinali zochepa pa 4-20mA kapena 0-20mA analog output yofanana ndi process variable. process variable idasinthidwa kukhala chizindikiro cha analog choperekedwa kuchokera ku chida kudzera pa waya ziwiri kupita ku indicator kapena control system, yokhala ndi makonzedwe ambiri, omwe amafunikira mwayi wolunjika kuti asinthe ndi manja ndi ogwira ntchito yokonza.

Ubwino womwe ungapezeke chifukwa cha ukadaulo wa digito pakugwiritsa ntchito zida za digito wadziwika pambuyo pake. Pakhoza kukhala zambiri zamtengo wapatali ndi ntchito zomwe zili mu chipangizocho, monga kukonza chipangizocho, malire a alamu, nthawi yogwiritsira ntchito ndi mikhalidwe yake, zambiri zodziwira matenda, ndi zina zotero. Kupeza deta yotere kumathandiza kukonza magwiridwe antchito a chipangizocho, ndipo pamapeto pake kumawongolera magwiridwe antchito.Ndondomeko ya HARTidatulukira ngati njira imodzi yoyambirira yopezera deta yosowa iyi kuti zipangizo zikhale zanzeru.

Ukadaulo wa HART umalola kulumikizana ndi chida cha analogi pogwiritsa ntchito chizindikiro cholumikizirana cha digito chomwe chimatumizidwa kudzera pa waya womwewo wa analogi. Chizindikiro cha digito ichi chimapereka kulumikizana kwa njira ziwiri pakati pa chipangizocho ndi wolandila popanda kusokoneza kutulutsa, zomwe zimathandiza kupeza deta yosiyanasiyana. Ndi HART, ogwira ntchito amatha kulumikizana ndi chotumizira ndikuchita makonzedwe kapena kuzindikira pamene chikuchita kuyeza njira yeniyeni.

 

Chotumiza cha WangYuan WP421A Chotenthetsera Kutentha Kwambiri Chokhala ndi 4~20mA + HART Protocol Output

 

Pa nthawi yomweyo, chitukuko cha matekinoloje ena a digito chinali kuchitikanso chomwe chikanatumizidwa kudzera m'misewu yolumikizirana yapadera, iliyonse ikupereka maubwino ake, kuphatikiza ukadaulo woyimira Fieldbus waProtocol ya Modbus yokhala ndi mawonekedwe a RS-485Modbus ndi njira yotseguka yolumikizirana pakati pa master-slave, yomwe imalola wopanga aliyense kuphatikiza njira yolumikizirana mu chida, kuti apereke mwayi wopeza zida zanzeru kuchokera ku makina osungira.

 

Chotumiza cha Pressure cha WangYuan WP401A Chokhala ndi RS485 Modbus Output & Ex-proof

Chifukwa cha kupita patsogolo kwa ukadaulo m'zaka makumi asanu zapitazi, kutumiza zida kwasintha kuchoka pa njira yoyambira yokha kupita ku chidziwitso chochuluka chomwe chikupezeka mpaka pamlingo wamakampani. M'tsogolomu, ukadaulo wa digito upitiliza kupereka zambiri kuchokera kwa otumiza, ndi njira zambiri zopezera.

Ku WangYuan, kampani yopanga zida ku China yokhala ndi zaka zoposa 20 yogwira ntchito yopangira zida, timaika patsogolo kugwiritsa ntchito njira zolumikizirana mwanzeru pazinthu zoyezera. Zinthu zathu zambiri zoyezera kuthamanga, mulingo, kutentha ndi kuyenda kwa magetsi zimalandira kusintha kwa ma signalo kuphatikizapo HART Protocol yolembetsedwa ndi maziko ndi RS-485 Modbus kuti zigwirizane ndi zosowa za ogwiritsa ntchito komanso momwe zinthu zilili.
