Njengedivayisi eyinhloko yokulinganisa ukusetshenziswa kwamandla ezinhlelweni zamandla, ukusebenza kwamamitha kagesi kuthinta ngokuqondile ukunemba, ukwethembeka, nokungakhethi kwesilinganiso samandla. Ngokuthuthuka okusheshayo kwamagridi ahlakaniphile nobuchwepheshe obusha bamandla, amamitha kagesi akumele nje ahlangabezane nemisebenzi eyisisekelo yokukala kodwa futhi abe namazinga aphezulu obuhlakani, amakhono okuxhumana, nokuvumelana nezimo zemvelo. Lesi sihloko sizohlola izinkomba zokusebenza ezibalulekile kanye nezidingo zobuchwepheshe zamamitha kagesi kusukela kumbono wokunemba, ukuzinza, ukwethembeka, ukuhlakanipha, nokuvumelana nezimo zemvelo.
Ukunemba Kwemitha: Inkomba Yokusebenza Okubalulekile Yamamitha Kagesi
Ukunemba kwemitha kagesi iyisidingo esibaluleke kakhulu sokusebenza, esithinta ngokuqondile ukulunga kwenkokhelo yenkokhelo kagesi wabasebenzisi kanye nokuthembeka kwedatha evela ezinkampanini zamagridi kagesi. Amazinga omhlaba (afana ne-IEC 62053) kanye nemithetho kazwelonke ngokuvamile ibeka izindinganiso eziqinile zokunemba kwamamitha kagesi. Amaleveli okunemba avamile ahlanganisa u-0.2s, 0.5s, 1.0, no-2.0, anezinombolo eziphansi ezimelela ukunemba okuphezulu. -Amamitha kagesi anembayo aphezulu ngokuvamile asebenzisa-iziguquli zamanje ezizinzile (CTs) kanye nama-voltage transformer (PTs), kuhlanganiswe nobuchwepheshe be-analog{10}}kuya{11}}ku-digital conversion (ADC), ukuze kuqinisekiswe ukukalwa okunembile ngaphansi kwezimo zomthwalo ezihlukene (njengesici samandla aphansi kanye{12}}nengozi ephezulu{12}). Ngaphezu kwalokho, amamitha ahlakaniphile kufanele afake{14}}amakhono okuzilinganisa ukuze agcine{15}}ukunemba kwamamitha wesikhathi eside.
Ukuzinza kanye-Nokwethenjelwa Kwesikhathi Eside
Ukuzinza kwemitha kusho ikhono layo lokugcina ukunemba kwemitha ngesikhathi esinwetshiwe sokusebenza. Izinto ezithinta ukuzinza zihlanganisa ukuguga kwengxenye, ukushintshashintsha kwezinga lokushisa, kanye nokuphazamiseka kazibuthe. -Amamitha ekhwalithi ephezulu ngokuvamile asebenzisa-izingxenye ze-elekthronikhi ezinokwethenjelwa okuphezulu futhi ahlolwe ngokusheshisa ukuguga ukuze kuqinisekiswe ukusebenza kwemitha okuzinzile esikhathini sesevisi yeminyaka engaphezu kwengu-10.
Ukuthembeka kusho amandla emitha okusebenza ezindaweni ezinokhahlo, njengamazinga okushisa aphezulu naphansi, umswakama, nokudlidliza. Amamitha ebanga lezimboni-ngokuvamile athobela izindinganiso zokuhambisana nogesi (EMC) njenge-IEC 61000, enikeza ukuvikeleka ekuphazameni kwesikhashana okufana nokushaya kombani nokukhuphuka, okuqinisekisa ukuqoqwa kwedatha akuthintwa imithelela yangaphandle yemvelo.
Ubuhlakani Namakhono Okuxhumana
Amamitha ahlakaniphile esimanje awagcini nje ngokuba nemisebenzi yokukala yamamitha endabuko emishini noma kagesi kodwa futhi ahlanganisa ama-microprocessors, inkumbulo, namamojula okuxhumana ukuze asekele ukufundwa kwamamitha akude, ukuphathwa komthwalo, ukutholwa okudidayo, neminye imisebenzi. Amamitha ahlakaniphile asebenzisa izindlela zokuxhumana ezilandelayo:
•Ukuxhumana okungenantambo (okufana ne-LoRa, i-NB-IoT, ne-Wi-Fi) yokusatshalaliswa kokusabalalisa;
•Ukuxhumana ngezintambo (okufana ne-RS-485 kanye Nenkampani Yenethiwekhi Yamandla (PLC)) yokuphatha okumaphakathi.
Ngaphezu kwalokho, amamitha ahlakaniphile ngokuvamile asekela izimiso zokuxhumana zomhlaba wonke ezifana ne-DLMS/COSEM ukuze kuqinisekiswe ukuhambisana nezinhlelo zokuphatha amandla ezivela kubathengisi abahlukene.
Ukuguquguquka Nokuvikeleka Kwemvelo
Amamitha kagesi angase afakwe ngaphandle, ezindlini ezingaphansi, noma ezindaweni zezimboni, ngakho kufanele abe nokuvumelana nezimo kwemvelo okuhle kakhulu. Izibonelo zifaka:
•Ibanga lokushisa elibanzi lokusebenza (isb, -40℃ukuya ku-+70 degree);
•Ukumelana namanzi nothuli (IP65 noma ngaphezulu);
•Idizayini ekwazi ukumelana nokubola{0}} ukuze isetshenziswe kumswakama ophezulu noma ezindaweni ezifuthwa ngosawoti. Mayelana nokuphepha, amamitha kagesi kufanele ahambisane namazinga okuphepha kagesi (afana ne-IEC 62052) ukuze kuvinjelwe izingozi ezifana nokushaqeka kukagesi, ukugcwala ngokweqile, namasekhethi amafushane. Kufanele futhi baqinisekise ubumfihlo bedatha yomsebenzisi futhi bavimbele ukufinyelela okungagunyaziwe noma ukuphazamisa.
Isiphetho
Ukusebenza kwamamitha kagesi kuthinta ngqo ukusebenza kahle kwezinhlelo zamandla kanye nezinga lokuphathwa kwamandla okukhaliphile. Ukunemba okuphezulu, ukuzinza okuphezulu, ubuhlakani, kanye nokuvumelana nezimo kwemvelo okuqinile kuyizidingo ezibalulekile zamamitha kagesi wesimanje. Ngokuthuthukiswa kwe-Inthanethi Yamandla, amamitha kagesi esikhathi esizayo azohlanganisa ubuchwepheshe obufana nokuhlaziywa kwe-AI kanye nokugcinwa kwedatha ye-blockchain ukuze kuthuthukiswe ukunemba kwemitha kanye nokusebenza kahle kokuphatha, ukuhlinzeka ngosekelo lwezobuchwepheshe oluthembeke kakhulu ekushintsheni kwamandla omhlaba.
