Ultimate Log reader

This is just a short article that describes our new program that just went out of beta mode:
The Ultimate Log Reader or ULR.

This is a World unique innovation that will enable you to get a diagnostic of your model systems in a few seconds.

The program was developed by Oistein, with my guidance.
Oistein is the code genius of our team and really is the father of this program.
He will follow up on this here.

The first stage of the program development is finished.
To keep things simple, Weatronic gave me the code to extract the data from the log files. This code was compiled by Oistein in QT libraries and then ported to the Windows platform. We worked on this code for a while, then decided to create our own parser for faster data extraction and elimination of the fake value appearing when discontinuities occur.

The program at this stage does what Gigacontrol is offering right now with the table view and 2D view. However it adds powerful statistical analysis ( Min, Max, mean, median, stdev ).
Furthermore the program has an auto flight extraction. This means that you can load a log in ULR that has a fligth in it. Then the program will extract the meaningful flight data and erase the rest.

The program offer two statistical analysis windows to characterize your flight RF link and your batteries performance ( Rx and Tx ).

At a second stage, domain analysis will be added to establish system fault statistical analysis an system fatigue characterization. This will use my knowledge of airline maintenance software like Airman, Taelis, AHM/ MAT. This uses complex algorithms with domain and data frequency analysis but will not be meaningful until we get enough modelers using the system.

However I can already tell you that this platform will be able to advise you of a turbine problem and what problem is coming up ( warped combustion chamber, clogged injectors, turbine wheel performance degradation, fuel pump problem, igniter problem ). This will be available through our ASSI system that will be compatible with Weatronic telemetry as soon as the engineers from Berlin release the SCU code to us.

The platform will also be able to advise about transmitter and receiver batteries degradation, servo performance degradation, binding flight control, antenna loss of sensitivity and airspace frequency jamming.
The software will also have an automatic antenna diagram detection and antenna placement recommendation.


Here are a few screen caps of the main screens.

The table screen presenting the data line by line according to time stamp and sample number:


The user plot screen that enables you to load the log you want and create 3 custom graphs with any of the data available from the left column.



The Link analysis screen that shows you the performance of your RF link for a given flight. This screen offers the option to extract flights to eliminate unwanted post and pre-flight data ( here shown un-ticked ):



And with the flight data extraction option ticked ( lots of non relevant data removed from the screen ):



On the two previous screens the data is pre-formatted as explained previously to match my method of RF link analysis and conform to the RF link database available on the blog below. Note that LQI mean value for Rx and Tx is computed and will give you a very precise insight on the performance of you RF link for the current flight.


The last screen is for batteries analysis. It will enable you to see the performance of your receiver batteries as well as monitor the health of your transmitter cells.


In the meanwhile, here is the link to the latest version.
