AMR(Automatic Meter Reading)Power Guard

What is AMR?

Although there are a variety of industry definitions, Automatic Meter Reading (AMR) can generally be regarded as the reading of a utility meter by a means, which does not require visual inspection of the meter.

Main Features

  • Monthly based billing data generation
  • Automatic back-up and GUI function
  • Customized restore function
  • Meter reading and control database and log file management
  • Selective searches in variety of type
  • Web based information providing easy services
  • Authentication and authorization grant

AMR Characteristics & Appplicable Targets

Specification
Characteristics
Applications
Wireless
 Initial invested cost : High
Expensive fee : 1 line/customer
Stabled wireless network
 High basic investment but wireless network is stable. Suitable for HV customers
CATV
 Initial invested cost : High
Expensive fee : 1 line/customer
Difficulty to assign fixed IP to every customer
CATV network area only
 Initial investment required too much
Limitation of area to be implemented
: Ended at the exemplary service level
RF
 Initial invested cost : Low
Economical Fee : 200 customers/line
Frequency split conflict and fee problem
With low invested cost, good for LV customers
But unstable network
Frequency split and fee are prerequisite
PLC
 Initial invested cost : Lowest
Economical Fee : 200 customers/line
 With low invested cost, good for LV customers
Exemplary service completed, the 3rd year project in progress
