On-Demand 1.2 Overview 5
Technical Brief
AclaraONE
®
The AclaraONE headend, is the central control for the entire system. Most utility
clients think of AclaraONE as the web portal that allows them to view readings,
monitor consumption and system health, and generate reports from the data it
contains.
Behind the scenes, it consists of four components or servers. These servers may be
on a single machine in a small Aclara RF™ AMI system, or they may be on
multiple machines in a larger system. Each of these servers has a primary function
that it performs:
The communication server provides communication services for the Aclara RF™
data collector units.
The database server is the central repository for storage meter readings and other
system information.
The web server provides access to the readings and other data stored in the
database.
The application server is the web interface that allows users, such as system
administrators and customer service personnel, to view readings, system data, and
reports.
As data flows into the communications server, it is logged and parsed and then sent
to the database server. The database server stores all the readings and system
performance data, as well as processing alarms. The web server communicates
with the database, feeding it information from the programming records uploaded
by MTU installers. It also provides users with a means to issue commands that are
sent to the database. The application server also communicates with the database,
issuing commands through a service bus from both a web job scheduler and the
web job generator.
