GPRS/PLC Automatic Meter Reading System AMI Solution for Data Collection and Management
Summarize
The remote meter reading system which is easy to be installed and debugged is an automatic addressing system, all terminal unit data sent to concentrator respectively by two wires non-polar M-bus cable, and collected, saved,statistical analyzed by data processing center which get data from concentrator via GPRS/Ethernet.
System configuration
The AMR system is composed with management software and hardware device.
Management software: a data processing center collecting, saving, statistical analyzing all terminal unit data and daily operations for administrators.
Communication channels
M-bus / RS485 cable from meters to concentrator
GPRS/Etherne from concentrator to data processing center
