Emirimu Emikulu
Omulimu gw’okupima
Eriko emirimu gy’okupima amasoboza ga DC mu maaso n’emabega era esobola okutereka data yaayo;Erimu omulimu gw’okupima obudde-okugabana,amasoboza g’amasannyalaze gakuŋŋaanyizibwa,gaterekebwa,era gasasulibwa mu biseera 1-4 okusinziira ku biseera ebikwatagana; Asobola okutereka amaanyi g’amasannyalaze gonna okumala emyezi 12;Obudde bw’ensalosalo y’okutereka data buba 24:00 ku nkomerero y’omwezi,oba obudde bwa buli ssaawa wakati wa 1st ne 28th buli mwezi.
Okupima n’okulondoola
Asobola okupima,okuwandiika,n'okulaga vvulovumenti ya kasasiro,akasannyalazo,amaanyi,n'obungi bwa mita y'amasoboza g'amasannyalaze, n'ensobi y'okupima (ensobi ya reference)tesukka± 1%.
Omulimu gw’Empuliziganya
Equipped ne RS485 interface emu, esobola okukung'aanya dual loop data.The empuliziganya protocol DL / T 645-2007 ekoleddwa okukwatagana ne Modbus RTU, era abakozesa basobola okusalawo okugikozesa themselves.The empuliziganya speed is 1200bps ~ 9600b,nga default ya 2400bps.
Okuzzaawo mita
Mita y’amasannyalaze esobola okukola omulimu gw’okuzzaawo ku ddaala lya bbaatule nga erina olukusa n’okukakasa obukuumi, era omulimu gw’okuzzaawo guwandiikibwa enkalakkalira ng’ekintu ekibaddewo.
Omulimu gw’okulaga
Eriko omulimu gw’okulaga button;
Ebirimu eby’okwolesebwa byawuddwamu ebika bisatu: emiwendo gy’omuwendo,koodi,n’obubonero;
Yuniti z’omuwendo eziragiddwa zitwala ebitundu by’okupima eby’amateeka eby’eggwanga;
Awagira okulaga emitendera gya bbaatule okutuuka ku bifo bya decimal 0-4.
Omulimu gwa freezing
Daily freeze: etereka amaanyi gonna agakola positive ne negative n’amasoboza ag’amasannyalaze ag’omutindo ogw’enjawulo ne data ekyukakyuka mu ttumbi buli lunaku, era esobola okutereka data okumala emyezi ebiri;
Timed freezing: Kisobola okutereka total positive ne negative active power, wamu n’amasoboza ne data ekyukakyuka eya buli rate,n’oku freeze data emirundi 60 mu kiseera ekigere.
Omusingi gw’Emirimu
DC electronic multi rate energy meter erimu micro-controller module,voltage sampling module,current sampling module,485 communication unit,LCD display module,ne working power module.Module ya voltage sampling ekuŋŋaanya obubonero bwa voltage okuyita mu high-precision, low-temperature drift voltage divider resistors;Module y’okutwala sampuli ya kasasiro ekuŋŋaanya obubonero bwa current okuyita mu manganese copper shunt;Oluvannyuma lw'omuddiring'anwa digital processing within the microprocessor,the collected signals are converted into pulse signals proportional to power for time-sharing accumulation,ekivaamu omugatte gw’amasannyalaze agakozesebwa n’emiwendo egy’enjawulo egy’emisolo.The RS485 communication module esobola okutuuka ku remote data exchange and upload parameters nga amasannyalaze parameters,ebibaddewo,freezing,obudde,n’ebipimo ebirala mu energy meter.This amaanyi meter integrates numerous emirimu,nga mw’otwalidde n’amasoboza okupima,okutereka n'okukola amawulire,okulondoola ebiseera ebituufu-,okufuga okw'otoma,n'okuwanyisiganya amawulire.
