YONGS embedded industrial computer ARK yog siv nyob rau hauv lub teb chaws substation computer tom qab saib xyuas: substation computer tom qab saib xyuas yog ib tug ntawm cov peev tseem ceeb nyob rau hauv lub tam sim no kev hloov kho ntawm lub teb chaws hwj chim system. Lub substation keeb kwm yav dhau los xyuas qhov system tsim los ntawm lub hwj chim system integrator zoo ua tiav lub sij hawm saib xyuas ntawm lub regional power grid, thiab muaj peev xwm visually xyuas lub transformers ntawm txhua lub substation thiab tshem tawm cov kev khiav hauj lwm raws li txoj cai thiab kev khiav hauj lwm tsis, kom cov substation neeg ua hauj lwm muaj peev xwm paub txog cov transformers ntawm txhua substation. tswj chaw taws teeb thiab kev nyab xeeb ntawm lub computer hauv lub sijhawm luv luv. Txhim khu kev rau txim rau kev cuam tshuam ntawm qhov chaw. Kev saib xyuas keeb kwm yav dhau los ntawm qhov system no yog tsim los ntawm YONGS industrial computer ARK-5280 industrial control field.
Qhov system xav tau:
Lub kaw lus yuav tsum muaj kev ntseeg siab thiab muaj peev xwm ua haujlwm nyob rau hauv cov xwm txheej tsis zoo rau lub sijhawm ntev. Lub substation feem ntau yog tsis muaj neeg saib xyuas. Yog tias pom muaj teeb meem, cov neeg ua haujlwm substation ntsib cov chaw taws teeb tswj ntawm lub khoos phis tawj hauv lub sijhawm luv luv, thiab kev nyab xeeb thiab txhim khu kev qha pov tseg ntawm kev cuam tshuam ntawm qhov chaw. Keeb kwm, keeb kwm yav dhau los saib xyuas cov khoom siv kho vajtse ntawm qhov system no muaj cov khoos phis tawj qub IPC ntawm YONGS. Qhov xwm txheej ntawm lub substation (siab kub, plua plav, electromagnetic, thiab lwm yam) yuav ua rau lub sij hawm ntev ntawm IPC industrial computer. Qhov kev tshawb pom ntawm kev cuam tshuam tau ua rau lub cev muaj kev ruaj ntseg ua haujlwm ntau.
YONGS ARK-5280 cov khoom nta:
A. Vim tias lub kiv cua tsis muaj zog nyob rau hauv qhov chaw muaj tshuaj lom, ARK series muaj lub computer siv lub zog siv hluav taws xob tsawg (CM / PM) kiv cua tsis muaj qhov tsim, uas ruaj khov thiab kub resistant, thiab zoo heev txhim kho MTTF mechanical (sib npaug thiab lub sijhawm tsis muaj kev cuam tshuam). ).
B. Lub aluminium alloy casing muaj ob peb nyob ntawm tej, thiab cov conduction thiab tshav kub dissipation ua rau nws muaj zoo sealing kev ua tau zoo, uas yuav zoo tshem tawm lub downtime los ntawm oxidation nyhuv ntawm plua plav thiab corrosive gas ntawm lub teeb conduction point, thiab txo cov txij nkawm. nqi. Nws yog haum rau siv nyob rau hauv lub hwj chim saib xyuas cov ntsiab lus thiab DCS daim ntawv thov nrog siab plua plav thiab kub hloov piv rau loj unmanned qhov chaw.
C. Nrog 2 PCI expansion phaib, nws tuaj yeem yooj yim nthuav cov haujlwm, xws li CAN muaj nuj nqi, thiab lwm yam nrog lub suab tso zis chaw nres nkoj, muab lub tswb tswj hom kev ntseeg tau, me me, yooj yim rau nruab, thauj, thiab tiv thaiv.
D. Kev sib koom ua ke ntau qhov chaw nres nkoj siv los ntawm ARK-5280 muab 4 serial chaw nres nkoj, tsis tas yuav mus los ntawm kev nthuav dav, uas tuaj yeem pab cov neeg siv txuag nqi, thiab tuaj yeem teeb tsa raws li RS422 / RS485 interface nrog kev tswj hwm ntws. . Nws serial chaw nres nkoj nta yog raws li nram no:
Txais serial chaw nres nkoj nti ADM213 kev ua tau zoo lub hom phiaj
Cov zis hluav taws xob viav vias ± 9V
Instantaneous conversion ceev siab tshaj 30V/μs
Kev hloov pauv ceev hauv thaj chaw hloov pauv tsis pub tsawg dua 5V / μs
Nws yog tsim rau RS232 tus qauv interface, cov zis tam sim no ntau dua 10mA, thiab luv luv tam sim no tus nqi siab tshaj plaws yog ± 60mA.
Transmitter tso zis, tso zis impedance 300Ω
Lub input voltage ntawm tus tsav tsheb yog {{0}}.3V rau (Vcc ntxiv 0.3V), thiab cov zis voltage yog (V ntxiv , ntxiv rau 0.3V) rau (V-, { {7}}.3V).
Vcc - fais fab mov voltage
Lub input voltage ntawm lub dab dej yog ± 3 0V, thiab cov zis voltage yog -0.3V rau (Vcc ntxiv rau 0.3V)
Overvoltage tiv thaiv
Electrostatic paug (ESD) tiv thaiv voltage ntau dua 2000V
Muaj cov tiv thaiv circuits sab hauv
E. Mechanism modularization txoj kev npaj - tom qab-muag yooj yim, luv MTTR (hindered sib npaug lub sij hawm kho)
Yog tias lub kaw lus tau txais Advantech's kiv cua-dawb thiab tsis muaj kev tiv thaiv embedded industrial computer ARK-5280 los ua txoj kev npaj tshiab, nws tuaj yeem txhim kho tag nrho cov kev ua tau zoo ntawm lub kaw lus, thiab muab 232/422/485 nplooj ntawv sib txuas lus, tsis tsim nyog. rov siv dua thiab kev nthuav dav Daim npav sib txuas lus txuag tus nqi thiab txhim kho kev ntseeg siab, thiab tseem ua kom yooj yim rau daim ntawv thov thiab kev tiv thaiv ntawm tus neeg siv khoom ntawm lub tsev.
Kev taw qhia txog qhov project:
Txais ELO lub vaj huam sib luag tiaj tus, ARK5280 muaj lub computer, 220V AC thiab DC dual-purpose fais fab mov los muab lub zog rau lub vijtsam LCD thiab tus tswv tsev los tsim ib qho kev tswj hwm, thiab phim rau sab nraum zoov enclosure los tsim lub substation xyuas qhov system.
Lub chaw substation qee zaus yuav tsum tau saib xyuas lub tsev ntawm qhov chaw, yog li nws muab cov khoom ELO LCD zaub rau cov neeg siv. Cov khoom siv hluav taws xob hauv lub txee ntawm lwm qhov chaw nres tsheb tsis sib koom ua ke, thiab siv AC thiab DC 220V fais fab mov. Txawm li cas los xij, ARK thiab Txhua ELO saib yuav tsum muaj cov khoom siv 24-volt input, yog li AC-DC fais fab adapter tau muab tso rau hauv qhov system. Cov khoom tau muab tso rau ntawm lub txee rau kev yooj yim installation thiab kev tiv thaiv.
System lus:
Kev sib txuas lus teb tsim los ntawm YONGS ARK-5280 (kev sib txuas lus tshuab), CAN kev sib txuas lus lub vev xaib thiab RS-485 nplooj ntawv web.
Lub kaw lus tau txais C lus txhim kho software, vim tias RS -485 ntawm YONGS ARK muaj lub computer muaj cov yam ntxwv ntawm kev khiav dej num, uas ua kom yooj yim rau kev sib txuas lus yooj yim heev. Kev siv cov ntaub ntawv khaws cia hauv lub sijhawm tiag tiag, cov ntaub ntawv khaws cia ntawm qhov chaw yog tas li nyob rau lub sijhawm, cov ntaub ntawv ntws yog loj, thiab nrog rau qhov nce ntawm cov ntsiab lus sau, cov ntaub ntawv ntws hauv chav tsev lub sijhawm kuj yuav nce ntxiv. Yog li, lub kaw lus xaiv Microsoft's SQL Server database ua cov ntaub ntawv khaws cia. Qhov qhib, yooj yim thiab lwm yam haujlwm muaj zog ntawm Microsoft SQL Server muab ib txoj hauv kev los khaws cov ntaub ntawv loj heev ntawm kev kub ceev thiab khaws cia hauv qhov chaw me me. Nws kuj tseem txuas ntxiv thiab tsim cov lus nug (SQL) kom ua tau zoo nug cov ntaub ntawv serial.
thesis:
YONGS ARK-5280 compact tsim yog ib lub tshuab computer tsis muaj kiv cua, ntau yam 232/422/485 interfaces thiab cov chaw nres nkoj network, thiab muaj qhov nthuav dav ntawm 2 PCI slots, nrog rau kev tso chaw yooj yim thiab ntau yam zoo, kom ua tau raws li qhov xav tau ntawm cov neeg siv hluav taws xob, hauv kev ua haujlwm ruaj khov ntawm substation tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom.
Nrog rau kev nce qib ntawm automation system ntawm lub zog hluav taws xob ua haujlwm, tag nrho automation system ntawm substations tau ua lub luag haujlwm tseem ceeb dua. Cov chaw me me lossis tsis muaj chaw nyob yuav dhau los ua txoj hauv kev ua ke ntawm kev ua haujlwm substation yav tom ntej. Tib neeg lub luag haujlwm yog qhov tseem ceeb. Tsuas yog los ntawm kev txuas ntxiv ua tiav peb cov kev tswj hwm cov khoom lag luam tuaj yeem ua raws li kev txhim kho sai ntawm lub zog hluav taws xob, ua peb lub zog rau kev vam meej ntawm kev lag luam hluav taws xob, paub tag nrho cov kev txawj ntse uas tsis muaj kev saib xyuas ntawm lub substation, thiab tsim ib qho kev daws teeb meem tshiab rau kev lag luam. fais fab kev lag luam. efficiency ntau dua.
