YONGS entegre òdinatè endistriyèl ARK yo itilize nan jaden an nan siveyans background òdinatè nasyonal poste: siveyans background òdinatè poste se youn nan priyorite yo envestisman nan refòm aktyèl la nan sistèm pouvwa nasyonal la. Sistèm siveyans background nan substation devlope pa entegratè sistèm pouvwa a efektivman konplete siveyans nan tan reyèl -nan kadriyaj elektrik rejyonal la, epi li ka vizyèlman tcheke transfòmatè yo nan chak poste epi klè estati a fonksyone ak paramèt opere, pou ke poste a. pèsonèl ka fè eksperyans kontwòl remote ak sekirite òdinatè a nan yon ti tan. Pinisyon serye pou obstak-sou sit la. Jan nou koumanse siveyans pyès ki nan konpitè jaden sistèm sa a konpoze de YONGS endistriyèl konpitè ARK-5280 endistriyèl kontwòl jaden.
Sistèm nan bezwen:
The system needs to be highly reliable and able to operate under relatively insidious conditions for a long time. The substation is usually unattended. If a problem is found, the substation personnel experience the remote control of the computer in a short period of time, and the safe and reliable disposal of the on-site disturbance. Originally, the background monitoring hardware field of this system consists of the ancient IPC industrial computer of YONGS. The situation of the substation (high temperature, dust, electromagnetic, etc.) will lead to the long time of the IPC industrial computer. The discovery of obstructions greatly increased the system's security workload.
Karakteristik pwodwi YONGS ARK-5280:
A. Paske fanatik la se yon obstak fèb anba anviwònman an pwazon, ARK seri òdinatè endistriyèl la adopte konsepsyon ki ba (CM/PM) fanless entegre, ki estab ak tanperati ki wo, ak anpil amelyore MTTF mekanik la (balanse ak tan san obstak). ).
B. Aman alyaj aliminyòm lan gen kèk fil andedan, ak kondiksyon an ak dissipation chalè fè li gen ekselan pèfòmans sele, ki ka efektivman elimine tan an ki te koze pa efè a oksidasyon nan pousyè tè ak gaz korozivite sou pwen an kondiksyon limyè, epi redwi antretyen an. pri. Li apwopriye pou itilize nan pwen siveyans pouvwa ak aplikasyon pou DCS ak gwo pousyè ak chanjman tanperati konpare ak gwo kote ki pa ekipe.
C. Avèk 2 kat ekspansyon PCI, li ka fasilman elaji fonksyon an, tankou fonksyon CAN, elatriye ak pò pwodiksyon odyo, bay mòd nan kontwòl alam se serye, ti nan gwosè, fasil enstale, transpòte, ak pwoteje.
D. Pwogram entegre milti-pò seri ki itilize pa ARK-5280 bay 4 pò seri, pa bezwen ale nan metòd ekspansyon, ki ka ede itilizatè yo ekonomize depans, epi yo ka configuré kòm yon koòdone RS422/RS485 ak koule. kontwòl. Karakteristik pò seri li yo se jan sa a:
Aksepte seri pò chip ADM213 sib pèfòmans
Output voltage swing ±9V
Instantaneous conversion speed maximum 30V/μs
The conversion speed in the transition area is not less than 5V/μs
It is suitable for RS232 standard interface, the output current is greater than 10mA, and the short-circuit current maximum value is ±60mA.
Transmitter output, output impedance 300Ω
Vòltaj antre chofè a se {{0}}.3V pou (Vcc plis 0.3V), ak vòltaj pwodiksyon an se (V plis , plis 0.3V) pou (V{{6 }}, -0.3V).
Vcc - vòltaj ekipman pou pouvwa
The input voltage of the sink is ±30V, and the output voltage is -0.3V to (Vcc plus 0.3V)
Gad ovèvoltaj
Pwoteksyon vòltaj elektwostatik (ESD) ki pi gran pase 2000V
Gen sikui gad andedan
E. Plan modularizasyon mekanis - apre-sann konvenyans, MTTR kout (tan reparasyon egalman anpeche)
If the system adopts Advantech's fan-free and guard-free embedded industrial computer ARK-5280 to carry out the innovation plan, it can greatly improve the overall performance of the system, and provide 232/422/485 communication pages, unnecessary reuse and application expansion The communication card saves the cost and improves the reliability, and also facilitates the application and protection of the user's on-site building.
Entwodiksyon pwojè:
Adopt ELO's flat panel display, ARK5280 industrial computer, 220V AC and DC dual-purpose power supply to supply power to the LCD screen and the host to form a control system, and match the outdoor enclosure to form a substation monitoring system.
Sit poste a detanzantan bezwen kontwole bilding lan sou plas, kidonk li entegre yon solid ekspozisyon ELO LCD pou itilizatè yo. Ekipman pou pouvwa a nan kabinè a nan lòt poste pa inifye, epi yo itilize ekipman pou pouvwa AC ak DC 220V. Sepandan, monitè ARK ak All ELO mande pou yon antre solid 24-volt, kidonk yon adaptè AC-DC entegre nan sistèm nan. Yo te mete pwodwi a sou etajè a pou enstalasyon fasil ak pwoteksyon.
Deklarasyon sistèm:
Jaden kominikasyon ki konpoze de YONGS ARK-5280 (machin pwosesis kominikasyon), paj wèb kominikasyon CAN ak paj wèb RS-485.
The system adopts C language development software, because the RS-485 of YONGS ARK industrial computer has flow control features, which greatly simplifies the programming complexity of communication. Adopting a real-time data collection system, the data collected on site is continuous in time, the data flow is large, and with the increase of collection points, the data flow in the unit time will also increase. Therefore, the system selected Microsoft's SQL Server database as the data storage field. The openness, simplicity and other powerful functions of Microsoft SQL Server provide a way to store large amounts of rapidly occurring data at high speed and store them in a relatively small storage space. It also extends and constructs query language (SQL) to effectively query serial data.
tèz:
YONGS ARK-5280 konsepsyon kontra enfòmèl ant se yon òdinatè endistriyèl san fanatik, miltip 232/422/485 interfaces ak pò rezo, e li gen ekspansyon nan 2 fant PCI, osi byen ke plasman pratik ak anpil lòt avantaj, satisfè kondisyon ki nan kliyan pouvwa, nan Operasyon ki estab nan poste a te byen resevwa pa itilizatè yo.
Avèk avansman sistèm automatisation operasyon griy pouvwa a, sistèm automatisation an jeneral nan poste ap jwe yon wòl pi plis ak plis enpòtan. Soustasyon ti oswa poukont yo pral vin metòd konbine operasyon poste alavni. Devwa imen se enperatif. Sèlman pa kontinye akonpli plan jesyon pwodwi nou an nou ka kenbe moute ak devlopman rapid nan sistèm pouvwa a, fè ti jan nou an pou pwosperite endistri pouvwa a, reyalize tout fonksyon entèlijan poukont yo nan poste a, epi kreye yon solisyon inovatè pou la. endistri pouvwa. pi wo efikasite.
