Wired communication RS485 AMI solutions for multi - dwelling storey buildings
RS485 is a baud commnication port within Calin's meter. It provides
the most comprehensive raw data of the meter including metrological
value, firmware version, tariff plans, interval settings, alarm
threshold, etc. Multi-storey buildings, multi-dweller complexing,
student dormitry, body corporates, section-tile community of
densely populated areas are perfect situation for this setup.
Meters are normally locked away from cutomers premises in a cabinet
or kiosk, allowing wired connection in most limited space. For
communication with the back end server, a data collector or
mini-concentrators can be utilized to link with the meter cabinet
as a group control unit, and through GPRS or cable connected to the
head-end server.
The communcation between the meter and the server is two-way,
meaning meter transmit data and receive command from the head-end
as well. A utility can implement load management control with the
data readout and analytic tools of the system.
Key Benefit
1) Two way communication IEC standards compliant
2) Stable connection from the bottom layer to the head-end servers (HES)
3) Automated meter readout and remote load management as in intrusive controls
4) Interface with billing system and any other third party system softwares
5) Easy and quick to setup
6) Reduced operational cost and labor cost for meter reading service
