Automatic Meter Reading System - IMAS

Integrated automatic meter reading system for residential user and industry user using GPRS, PLC, Ethernet and Zigbee technology

Electricity Information Integrated Management Automation System (IMAS) is an efficient, economical and reliable All-In-One solution for automatic meter reading (AMR) and management.

Integrate electricity power level of:

High voltage (HV) metering for substationsMiddle voltage (MV) metering for C&I (Large-Scale) Consumers /Distribution Transformers (DT)Low voltage (LV) metering for residential

Integrate business applications of:

Data managementReport & graph analysisEvent alarmLine loss analysis

Integrate database interface with:

Management Information System (MIS)Customer Information/Service System (CIS)Billing SystemSCADAGeographic Information System (GIS)

We provide customers end-to-end solution from all kinds of meters, terminals, concentrators and application software to the utility back office. Our successful turn-key experience in domestic market makes us recognized as the largest and best AMRS provider in China. Also, our AMRS are mass used overseas in Thailand, Uzbekistan, etc.

System Functions

Data acquisition: KWH / KW / KVAR / Voltage / Current / Demand / PF / Phase Angle / Frequency, etc.Automatic calculation & statistics: Statistics of raw data, line loss data, etc.Working condition monitor & analysis: Power quality supervision, line loss analysis, power load analysis, meter status, etc.Event log & alarm: Support more than 60 kinds of abnormities record and send SMS to duty person. (need local mobile network support) E.g.: Voltage loss, open phase, reversed phase, abnormal CT status, network failure, hardware failure, electricity tampering, etc.Load control: Automatic/manual switch on/off. Can be controlled by demand/energy threshold.Report forms, graph & curvesWEB service: Users can access to HL3000-WEB from anywhere has internet connectionSave data as other format: Support save data as MS Excel®/PDF/TXT(CSV)/XML format from HL3000-WEB or HL3000 serverReal-time time synchronizing.

System Features

Database sharing: Interface with other applications (MIS/EMS/SCADA/SAP®)Live updates and remote meter settings via mobile networkSmart communication: Can be self-adapted with any GSM/GPRS/CDMA networkPLC/Zigbee for residentialConsideration of stability and reliability1) Distributed network system structure 2) Redundant as dual machines dual networks clusters, dual server hot backup, double machines mutual backup, disc array mode, etc. Universal hardware platform: Users can select hardware equipments like of the brand they are familiar with.High security of system and data processing at 4 levels.

Performance Parameter

System capacity: Number of terminals ≥30000, number of metering points ≥50000. Data volume is restricted by hard disc capacity in principleSystem clock error: < 0.1 s;Master station and terminal clock error < 0.5 s;Data precision: equal to the precision of meter reading data;System normal communications can be guaranteed when communications error rate is less than 10-4;System serviceability: 99.9%;System mean time between failures (MTBF) ≥20000h
