Using analytics nodes¶
You can use analytics nodes to analyze and process time series data from Industrial IoT with standardized analytics methods. The assignable parameters control the analytics node.
Example scenario¶
The owner of the logistics center of the smart city would like to view the energy consumption of its cranes over different time periods: hour, day, week and month.
The previously created flow allows the power peaks of a crane to be identified.
Objective¶
A distribution of the energy demand is to be determined and the average displayed.
Requirement¶
- The crane is connected to Industrial IoT and collects the energy data.
- The flow for determining the energy consumption of the cranes has already been created in Visual Flow Creator.
Procedure¶
To use an analytics node, follow these steps:
-
From the node palette, drag and drop the following nodes from the required palette to the working area.
- Inject node
- Read timeseies node
- Moving average node
- Two debug node
-
Connect the nodes in a flow as shown below.
-
Double-click on any node to edit their properties.
- Save and execute the flow.
The existing flow uses the analytics node "moving average" to generate a moving average of the energy consumption of the crane.
The step edges of the energy consumption acquired become flatter and reflect a consumption profile that can be interpreted much more effectively based on a lower resolution.
