AMR (Automatic Meter Reading) System

OVERVIEW - AMR System AMR Definition:  AMR stands for Automatic Meter Reading.  AMR is the remote collection of consumption data from customers' utility meters.  AMR can use power-line, telephony, RF, cable communication technologies.  AMR provides electric, water, gas and heat utilities the opportunity to increase operational efficiency, improve customer service, reduce data-collection costs and quickly gather critical information that provides insight to company decision-makers  AMR Communication Mode 1. Uplink (Concentrators to Central PC):GPRS/GSM/CDMAPSTN 2. Downlink (Concentrator to Meters)Power-LinesCable - RS485, Can-Bus, M-Bus, ¡­RFCATVLAN AMR mainly depends on downlink communication channels • PLC IC - PLC Technology Power Line Characteristics  Severe Interference Noise  Low and time-varying Impedance  Communication Signal Attenuation  Complicated Network Structure Solutions of the Problems  Spread Spectrum Communication (SSC)  Digital Signal Processing  Optimal Frequency Selection  Effective Signal Coupling  Up to date Relay-Route Arithmetic  Perfect Data Communication Protocols JAZ® AMR System - Components JAZ® AMR System consists of four parts: 1) Watt-hour meters with two-way communicationSingle phase or three-phaseIncluding multi-user kWh meter, electric display unit 2) Concentrator 3) Automatic meter reading software 4) PLC modem and HHU for manufacture or debug • Features • Use existing power lines as communication channel, no need for extra cabling • Reduce data-collection costs, increase operational efficiency, improve customer services • Remotely and quickly access consumer's meter data • Real time monitor consumer's meter operation • Process and report consumer's data • Analyzing power consumption of an individual consumer or all • Tamper detection and remotely shutoff control • Freezing consumers' power consumption, analyzing system losses • Providing tariff and billing • System is reliable, stable and robust
