Imisebenzi Esemqoka
Umsebenzi wokulinganisa
Inemisebenzi yokulinganisa yamandla e-DC eya phambili noma ehlehlayo futhi ingagcina idatha yayo;Ifakwe isikhathi-umsebenzi wokwabelana wemitha, amandla kagesi aqoqwa, agcinwe, futhi akhokhiswe phakathi nezikhathi zesikhathi ezingu-1-4 ngokuvumelana nezikhathi zesikhathi; Ingagcina isamba samandla kagesi kufikela ezinyangeni eziyi-12;Isikhathi somngcele wokugcinwa kwedatha ngu-24:00 ekupheleni kwenyanga, noma isikhathi sehora phakathi komhla woku-1 nowama-28 wenyanga ngayinye.
Isilinganiso kanye Nokuqapha
Iyakwazi ukulinganisa, ukurekhoda, nokubonisa i-voltage yamanje, yamanje, amandla, kanye nenani lemitha yamandla kagesi, enephutha lokulinganisa (iphutha lesithenjwa) elingadluli ku-± 1%.
Umsebenzi Wokuxhumana
Ifakwe isixhumi esibonakalayo esisodwa se-RS485, esikwazi ukuqoqa idatha ye-loop ekabili.Iphrothokholi yokuxhumana i-DL/T 645-2007 yakhelwe ukuthi ihambisane ne-Modbus RTU, futhi abasebenzisi bangakhetha ukuyisebenzisa ngokwabo.Ijubane lokuxhumana ngu-1200bps~9600b,nokuzenzakalelayo okungu-2400bps.
Ukusetha kabusha imitha
Imitha yamandla kagesi ingenza umsebenzi wokusetha kabusha ezingeni lebhethri ngokugunyazwa nokuqinisekisa ukuphepha, futhi umsebenzi wokusetha kabusha urekhodwa unomphela njengomcimbi.
Bonisa Umsebenzi
Ifakwe umsebenzi wokubonisa inkinobho;
Okuqukethwe okuboniswayo kuhlukaniswe ngezinhlobo ezintathu: amanani ezinombolo, amakhodi, nezimpawu;
Amayunithi ezinombolo abonisiwe asebenzisa amayunithi kazwelonke wokulinganisa okusemthethweni;
Isekela ukubonisa amazinga ebhethri ezindaweni zedesimali ezingu-0-4.
Umsebenzi wokuqandisa
Ukuqandisa kwansuku zonke: kugcina amandla asebenzayo asebenzayo namahle kanye nenani elihlukahlukene lamandla kagesi kanye nedatha eguquguqukayo phakathi kwamabili nsuku zonke, futhi ingagcina idatha izinyanga ezimbili;
Ukuqandisa okunesikhathi: Kungagcina amandla asebenzayo aphelele kanye namabi, kanye namandla nedatha eguquguqukayo yesilinganiso ngasinye, futhi imise idatha izikhathi ezingu-60 phakathi nesikhathi esimisiwe.
Isimiso Sokusebenza
I-DC electronic multirate energy meter ihlanganisa i-micro-module yesilawuli, i-voltage sampling module, i-current sampling module,485 communication unit, i-LCD display module, kanye nemojuli yamandla okusebenza.Imojuli yesampula ye-voltage iqoqa amasignali kagesi ngokunemba okuphezulu, okuphansi{4}}kwezinga lokushisa eliphansi{4}lokushisa kwe-voltage divider resistors;Isampuli yamanje yesampula ye-shupper ye-collection yamanje ye-mamodule ye-collections ye-collections yamamojula ukucutshungulwa kwedijithali ngaphakathi kwe-microprocessor, amasiginali aqoqiwe aguqulwa abe amasiginali we-pulse ngokulingana namandla esikhathi-okuqoqwa kokwabelana, okuholela ekusetshenzisweni kukagesi okuphelele kanye namazinga entengo ahlukahlukene.Imojula yokuxhumana ye-RS485 ingakwazi ukufinyelela ukushintshisana kwedatha okukude futhi ilayishe imingcele efana nemingcele kagesi, imicimbi, ukubanda, isikhathi, kanye neminye imisebenzi yamandla ehlanganisa amandla. ukulinganisa amandla, ukugcinwa kolwazi nokucutshungulwa,{9}}ukuqapha isikhathi sangempela, ukulawula okuzenzakalelayo, kanye nokushintshisana ngolwazi.
