Data transmission can include any combination of the above
mentioned methods.
Remote Maintenance
Reporting functions can also be efficiently used for remote
maintenance by:
- the system monitoring itself with real-time self-diagnostics tasks
and providing system alarms in case of system failure,
- providing system maintenance information to the system operators
remotely, so that the system status can be analyzed and required
maintenance procedures planned in advance prior to maintenance
on site, and
- providing a maintenance interface to maintenance technicians on
remote sites.
A system status message can include information on internal
temperature, available battery capacity and the status of charging,
amongst other things. In addition, hardware and software version
numbers can be included in these messages. This message can be
transmitted e.g. once a day at a set time, typically at midnight.
Logged Data in Reports
In the MAWS systems, it is possible to format output reports using the
data items in logged data files. The user can select the number of
records from the logged file to be included in the report. There are two
automatically made report formats. When using the SCAN format, the
logged data items are organized in columns, in such a way that one
column consists of the measurements of one item over a user-set
period of records. In the CHANNEL ordered report format, the logged
data are organized in rows, with one row consisting of the
measurements of one item over a period of records. The data items are
by default separated by a space, but the user can also change this
parameter.
This option is most convenient when the data is not needed in nearreal-time
but will be sent e.g. every 3 or 6 hours only.
