Automatic Meter Reading Via Cellular Networks

Date:2012-03-07 14:16:00

Automatic meter reading, or AMR, is the technology of automatically collecting consumption, diagnostic, and status data from energy metering devices (gas, electric) or water meter and transferring that data to a central database for billing, troubleshooting, and analyzing.

They are major three topologies for AMR systems by using cellular networks: 

1. Each meter is connecting to F2103 smart GPRS modem via RS232 by using CSD (data call);
 \
 
2.Each meter is connecting to a F2103 smart GPRS modem via RS232 by using GPRS(meter control the modem via AT commands);
\
 
 3. Each meter is connecting to a Data Concentration Units (DCU), which may support up to 32 meters,and each DCU is connecting to a F2103 Pro serial to GPRS gateway via RS485 by using GPRS (transparent transmit serial data to billing center automatically).
