Normalise Filter Plugin

The flir-filter-normalise plugin allows the user to normalise the timestamps of all readings that pass through the filter. The filter will extrapolate from the available data to produce data at a set rate. This particularly useful when data is coming from multiple sources at the data from each is not create at precisely the same point in time.

When adding a normalise filter to either the south or north, via the Add Application option of the user interface, a configuration page for the filter will be shown as below;

• Rate: The desired rate at which the readings should emerge from the filter to the next element of the data pipeline.

• Unit: The unit that the above rate is expressed in, e.g. per hour, per minute or per second.

Click on the Enabled option and then click on Done to add the filter.
