Chosinthira deta cha HART cha PH-SM100-M

Chogulitsa Chiyambi

Chosinthira deta cha PH-SM100-M cha HART ndi chinthu chopangidwa pogwiritsa ntchito microprocessor ya ARM, HART protocol modulation ndi demodulation ASIC, ndipo chimagwiritsidwa ntchito ndi ntchito zambiri zothandiza. Chapangidwa molingana ndi zofunikira za zinthu zamafakitale zomwe zimakhala zodalirika komanso zokhazikika. Chosonkhanitsa deta chili ndi mawonekedwe okhazikika a RS 485, mawonekedwe a RS 232 ndi chipata, zomwe zimatha kutumizidwa mowonekera ku chida chanzeru ndi protocol ya HART kapena kusinthidwa kukhala MODBUS_RTU kapena protocol ya MODBUS_TCP kuti muwerenge deta, kuti muwonetsetse kuti deta itumizidwa nthawi yeniyeni.

Ndondomeko ya HART imatsatiridwa ndi muyezo wa Bell202 Frequency Shift Keying (FSK), ndipo imasintha ma siginecha a digito pamaziko a 4~20mA, zomwe zimapangitsa zida za protocol ya HART kulumikizana ndi deta ya bidirectional popanda kusokoneza chizindikiro cha analog cha 4-20mA. Osonkhanitsa a SM100-M HART Date ndi a bidirectional modulation ndi demodulation ndi ma siginecha a digito ndi ma siginecha a analog.

Zinthu Zamalonda

● chithandizo cholumikizira 8 HART zidanthawi yomweyo.

● chithandizo Kusanthula nthawi imodzi kwa njira zonse za HART zomwe zakonzedwa ndi HART data collector.

● tkudzipatula kwa ma elekitiromagineti atatu pakati pa Ma channel a HART ndi magetsi a mainframe atha. Channel iliyonse imagwiritsa ntchito mawaya awiri, ndipo magetsi a HART module electromagnetic isolation voltage ndi osachepera 1500 V, omwe amathandizira ntchito yolekanitsa chizindikiro cha HART /4~20.

● Mawonekedwe a RS485, NET Ethernet interface isolation voltage osachepera 1500 V.

● gwiritsani ntchito kapangidwe ka modular kolekanitsa HART module ndi kompyuta yayikulu,ndipo imathandizira ntchito yosintha gawo la HART pa intaneti mu njira iliyonse.

● njira iliyonse ili ndi kuwala kosiyana kosonyeza kuti zipangizo za HART zili pa intaneti, chizindikiro cha momwe zida za HART zimalumikizirana.

● yokhala ndi chizindikiro cha momwe zinthu zilili pa chipangizo: kuthamanga/kulakwitsa, mawonekedwe olumikizirana, ndi zina zotero.

● kuchuluka kwa data yotsitsimula pa njira iliyonse

● mawonekedwe othandizira a Ethernet (osachepera 100 Mbps) ndi mawonekedwe a RS485.

● thandizani malangizo enieni a HART kuti muwerenge HART ID. ya zipangizo zonse za HART

● chithandizo cha kasinthidwe ndi njira yoyendetsera, kuthandizira makonda akutali a Telnet.

● imathandizira zosintha za firmware yakutali.

● kuthandizira kukhazikitsa njanji yoyendetsera bwino ya DIN.

● Kutumiza chizindikiro cha analogi ndi kulondola kwa 4 ~ 20 mA sizimakhudzidwa ngati zipangizo zili bwino kuzima magetsi kapena kulephera kugwira ntchito, ndipo kukana kwa dera kumakhala kochepera kapena kofanana ndi 250R.

● chipangizochi sichipereka mphamvu ku zida zakumunda.

● Ver5.0. Ndondomeko ya HART Yogwirizana
