Sensor Data Explorer

Introduction

Sensor Data Explorer (SDE) is a tool for viewing, filtering, performing basic statistics and data visualization on sensor data from various sources like SOS, DLS and Local System. It is an application in TCUP which enables user to register sensor, create data sources, view a data source’s data in different forms (grid and chart) perform basic statistics over data etc.

Purpose of the Document

The following document describes the basic steps to work with Sensor Data Explorer. After going through this, the users will able to

Import Data from SOS

This section enables user to import existing data from SOS. On clicking Import data from SOS user will land to the page as shown in the following figure.

Here user will be able to see the already created sensors. User must provide a data source name, description and then select the required sensor from the list of sensors. Now the user needs to select filter. Following filters are available in the filter drop down

1. Between Time Range – Here user have to select the start date/time and the end date/time for the datasource.

2. N Observations – Here the users have the option to select 1st or last N observations.

3. Time Expression - User can select a required time span to fetch the latest observations for a particular sensor. For eg: 1 day 3 hours 23 min 2 sec.

After filling up all the required fields click on the Save Data button or Save and View Data button to create a data source successfully. Save Data will create a data source whereas Save and View Data button will create a data source as well as navigate the user directly to the data source specific Explorer page.

Register Sensor in SOS

This section enables user to create new sensor. On clicking Register Sensor in SOS user will land to the following page. After adding all the required data click on register sensor button to create a new sensor. Please note if you attach the sensor with feature the feature should already be present in the system.

Import/Upload data in DLS

On clicking Import/Export data in DLS user will land to a page which enables user to either import data from DLS Catalogue or Upload data from Local System to DLS Catalogue.

1. Import Data from DLS catalogue

To import data from DLS user need to give the data source name and data source description. Then on clicking the desired folder from DLS Catalog field all the available CSV files are listed on right hand side. Select the required file and click on the Save as Data Source button to create a data source successfully.

2. Upload data from Local System to DLS Catalogue

2. Edit a Data Source

Clicking on edit button will redirect to the edit data source page. User will able to do the required modification there. Please note the Data Source Name is non editable.

3. Delete Single Data Source
