Mai sauya bayanai na jerin HART na PH-SM100-M

Samfuri Gabatarwa

Mai canza bayanai na jerin HART na PH-SM100-M samfuri ne da aka haɓaka ta amfani da microprocessor na ARM, daidaitawar yarjejeniya ta HART da kuma rage darajar ASIC, kuma yana da ƙwarewa da aikace-aikace da yawa masu amfani. An tsara shi bisa ga buƙatun samfuran masana'antu tare da babban aminci da kwanciyar hankali. Mai tattara bayanai yana da tsarin haɗin RS 485 na yau da kullun, hanyar haɗin RS 232 da ƙofar shiga, wanda za'a iya aika shi a sarari zuwa kayan aikin wayo tare da tsarin HART ko canza shi zuwa tsarin MODBUS_RTU ko MODBUS_TCP don karanta bayanai, don tabbatar da watsa bayanai a ainihin lokaci.

An bi ka'idar HART bisa ga mizanin Bell202 Frequency Shift Keying (FSK), kuma tana daidaita siginar dijital bisa ga 4~20mA, wanda ke jagorantar kayan aikin HART zuwa sadarwa ta bayanai ta hanyoyi biyu ba tare da katse siginar analog na 4-20mA ba. Masu tattara kwanan wata na SM100-M jerin HART sune don daidaitawa ta hanyoyi biyu da kuma rage girman siginar dijital da siginar analog.

● tallafi don haɗawa 8 HART kayan kidaa lokaci guda.

● tallafi duba dukkan tashoshin HART da aka tsara ta hanyar tattara bayanai na HART.

● tkeɓancewa ta hanyar amfani da na'urar lantarki mai tashoshi uku tsakanin Tashoshin HART da babban ƙarfin wutar lantarki sun cika. Kowace tashar tana amfani da hanyar sadarwa ta waya biyu, kuma ƙarfin lantarki na warewar lantarki na HART module bai gaza 1500 V ba, wanda ke tallafawa aikin rabuwar siginar HART /4 ~ 20.

● RS485 interface, ƙarfin raba hanyar sadarwa ta NET Ethernet ba ƙasa da 1500 V ba.

● yi amfani da tsarin zamani na raba tsarin HART daga babban kwamfuta,kuma yana goyan bayan aikin maye gurbin tsarin HART akan layi a kowace tasha.

● kowace tasha tana da hasken nuni daban don samar da kayan aikin HART akan layi, alamar yanayin sadarwa na kayan aikin HART.

● tare da alamar yanayin kayan aiki: gudu/laifi, hanyar sadarwa, da sauransu.

● ƙimar sabunta bayanai a kowace tasha

● tallafawa hanyar sadarwa ta Ethernet (ƙimar ba ta ƙasa da 100 Mbps ba) da hanyar sadarwa ta RS485.

● tallafawa umarnin HART na mallakar HART don karanta HART ID. na duk na'urorin HART

● tsarin tallafi da yanayin aiki, tallafawa saitunan nesa na Telnet.

● yana goyan bayan sabunta firmware na nesa.

● tallafawa tsarin DIN na yau da kullun.

● watsa siginar analog da daidaito na 4 ~ 20 mA ba su shafi lokacin da kayan aikin ya zama na al'ada ba kashe wuta ko rashin aiki, kuma juriyar da'irar ta ƙasa da ko daidai take da 250R.

● wannan kayan aikin ba ya samar da wutar lantarki ga kayan aikin filin.

● Ver5.0. Yarjejeniyar HART mai jituwa
