Table 1-1 Types of data collected by the scheduled task
Type Description
Daily frozen data Daily frozen record that an AR500
periodically collects from meters
Monthly frozen data Monthly frozen record that an AR500
periodically collects from meters
Hour frozen data Hour frozen record that an AR500
periodically collects from meters
Curve frozen data Frozen record that an AR500 collects from
meters within an hour
Meter event Record of a specified event such as meter
box opening
l Supplementary meter reading
The AR500 reads meter data that is not read by timed meter reading tasks, when the
collection channel is idle. The AR500 can cyclically read data from each meter where data
fails to be collected each day. The data includes curve frozen data, hour frozen data, daily
frozen data, monthly frozen data, and data that fails to be collected in the event collection
task.
Status Collection
The AR500 collects status changes that occur when the meter box, terminal cover, or meter cover
is opened. Meter box opening is used as an example to describe how the AR500 collects, stores,
analyzes, and processes status data.
The AR500 is installed in a meter box and provides real-time monitoring for the meter box. This
function prevents meter data from being modified.
1. When the meter box is opened or closed, an open or close signal is generated.
2. The AR500 monitors open or close signals in real time, and stores status change
information.
3. The AR500 reports the meter box status to the front end processor, and the front end
processor reports the meter box status to the MDM for exception analysis. The front end
processor can also periodically query meter status change information. The meter status
change information helps you determine whether the meter box is opened normally or
maliciously.
NOTE
The following conditions must be met:
1. The di command has been executed to configure the digital input (DI) channel and attribute flag
of the status data that an AR500 needs to collect.
2. The event command has been executed to configure status change events as major events.
