AMR (Automatic Meter Reading)
Every Utility / Discom is fighting to find a solution for this problem
PROBLEMS
• Protocol
• Communication Ports
• Existing Meters
• Technology
• Implementation Time
• Few More
PROBLEMS
•
Protocol
No common, Standard / open protocol
is available in the energy meters available nor the
meters which are being purchased.
Standard Protocol :•
PACT (Multi dropping not possible)
Open Protocol :-
•
Modbus ( Values are integers have to use
multiplying factor at software end)
•
IEC 101 (No known meter available)
PROBLEMS
•
Communication Port
No common type of port is available in the
energy meters available nor the meters which are
being purchased.
The mixture of Optical, RS-232 and RS-485 is
available and none has the record of the ports.
Recommended :RS-232 for the meters installed individually
RS-485 for the meters installed in groups
(Substation, Group Metering)
PROBLEMS
•
Existing Meters
As these meters vary in technologies, makes,
Protocols, communication ports, etc. which creates
a difficult situation for AMR implementation teams.
Recommended :Request the manufacturer to take back old meters
and replace with new ones, as in many a cases it is
only firmware up-gradation or minor modification.
PROBLEMS
•
Technology
As these meters vary in technologies, makes,
protocols, communication ports, etc. which creates
a difficult situation for AMR implementation teams.
Recommended :Request the reshuffle / change energy meters to
create the situation for the AMR supplier to opt. one
technology / methodology for the system.
Example : Change all substation meters with the
ones having RS-485 port & Modbus protocol.
PROBLEMS
•
Implementation Time
As these meters vary in technologies, makes,
protocols, communication ports, Multiplying factors
etc. which creates a difficult situation for AMR
implementation teams.
Recommended :Request the reshuffle / change energy meters to
create the situation for the AMR supplier to opt. one
technology / methodology for the system.
This will reduce the AMR implementation time
drastically.

• Instant control on consumers
• GPRS devices are part of company LAN
GPRS FOR SUBSTATION AMR
GPRS
•General Packet Radio Service
•Wireless packet data channel
•Based on GSM technology and networks
•Designed for TCP/IP traffic
•Dynamic radio channel allocation
•Faster data transfer compared to GSM data
•Public network, Global - low initial investments
GPRS Arctic Key Features
• Industrial grade GPRS router

Key Features
Configuration and Management :
The Arctic GPRS Router is configured using a www browser. A conventional
console interface is also provided. The software of Arctic GPRS Router can be
updated over the network.
Network Protocols :
PPP, IP, ICMP, UDP, TCP, ARP,
DNS, DHCP, FTP, TFTP,
HTTP, SNMP, POP3, SMTP
Tunneling (VPN) :
SSHv2 server and client
SSHv1 server and client
Communication Protocols :
Modbus, Modbus Ethernet, Transparent
Mode, IEC 101, IEC 104, etc
EDGE
•Enhanced Data rates for GSM Evolution
•EDGE is update for GPRS, also referred as EGPRS
•More efficient radio modulation than in GPRS (8-PSK)
•Speed is about 3-5 times more than in GPRS
•236.8 kbit/s for 4 timeslots and theoretical maximum is
473.6 kbit/s
•Uses same base stations and core network as GPRS/GSM,
easy and cost-effective for operators
•Typical download speed about 15 kilobytes/s
