Home > Capabilities > Data Handling and Processing

Data collection, handling and processing in an efficient way is a task that LRW undertakes on a daily basis. We use both PC based data collection and data loggers. All of our data is tracked and stored, and post-processing can be performed in a whole host of manners - whether this be simple distribution plots, data mapping for statistical analysis or complete recalculation to simulate a software or calibration change.

Tool design, development and data analytics

We regularly develop bespoke applications and tools to aid with statistical data processing and to model how a software or calibration change will effect a range of outcomes, from system response to IUMPR statistics. This  ensures that the best solution is reached in a timely fashion, and that all previous data is not made redundant should a change be necessary. Our tools can handle single data files with real-time analysis view or can process thousands of files to display the user defined outcomes.

 

As well as software modelling, our data processing tools can provide Gaussian frequency analysis, scatter mapping, 2D graphical representations and 3D mapping of multiple files for comparison. These include customisable release conditions of the data to collect based on logged data or calculated from other conditions in the data, as well as point counts to ensure the validity of the data.

In addition to manual data review, an in-house tool - Hound - has been designed to process swathes of data and plots statistics such as: time-in-a-row duration over a threshold; duration of signals over a percentage of other logged signals; maximum value reached and ratio of a signal to a threshold. Hound also encompasses an OK/NOK overview based upon user defined thresholds.

Processing tools can be developed or modified should any extra functionality be required.

LRW also have experience in 6 sigma statistical analysis for problem definition and resolution.

Data loggers and remote data capture

Where it is impractical to log data with the PC based software we use, data loggers play a large role. This is especially the case with emissions testing where facilities are run around the clock and engineers may not be able to attend. We are able to use data loggers to log specific tests or log continuously, these can also automatically make calibration changes based on events that occur.
