teLoad

The universal Solution for Data Import into MATLAB

Abstract

Sophisticated projects often generate manifold measurement and simulation files created by various hardware systems stored in various data formats.

To allow consistent analysis of data in any format within MATLAB ®, teLoad supplies a standardized interface.

Characteristics


To achieve the maximum performance the data is loaded by an import filter level written in C/C++.

teLoad not only transfers the data to MATLAB ®, but also allows access to any available meta-information (i.e. sensor calibration data or test configuration) available within the data source.

 
All data formats supported by our data analysis software testeval or our data conversion software teconvert are available to teLoad and vice versa.

Numerous data formats which are widely used within the automotive and aerospace industry are supported by available drivers, e.g.:

  • BDF (testingsolutions),

  • D97 (Bosch),

  • MDF / DAT (INCA, ETAS),

  • DAT (DiaDem, National Instruments),

  • ASAM-ODS (ASAM e.V.),

  • MAT (MATLAB ®, The Mathworks),

  • ASCII (any text format including meta-information)

Additional data formats can be added upon short notice. testingsolutions has excellent experience concerning the implementation of all kinds of data formats.

The possibility to select individual data channels and time intervals as a subset of of the complete test before actually loading the data reduces the required loading time significantly. Additionally, the required amount of memory is reduced thus enabling faster data analysis.

A quick-view function supplies information about the time interval enclosed within the file and the available data channels as well as the total file size.

The data transfer to MATLAB ® is configurable:
  • data only

  • data and meta information

teLoad is available for all MATLAB ® versions since 6.1 (Release 12.1) for Windows and Linux.

The data can be loaded directly by a command in the MATLAB ® command line or in a m-file.
Optionally the graphical user interface can be used to inspect the data available within a data source and to select the data subset to be loaded.


Advantages


  • teLoad enables the access to data in any format from within MATLAB.

  • Data from different sources is available within MATLAB ® in a standardized format.

  • The usage of teLoad makes data conversion obsolete.

  • Redundant data is eliminated as the data no longer neds to be saved in a .mat-file.

  • Only the required amount of data is loaded.

  • The data management can be centralized on a network file server.

Simulink


teLoad enables access to logged data from within your Simulink-models i.e. to stimulate your model with real measurement data. The teLoad-Simulink-block simplifies the configuration of the desired data.


Integration


teLoad can be easily implemented into existing applications and can be compiled through the MATLAB ®-Compiler.


Maintainability


Changes at the data creation system have no impact on any of the subsequent data processing tools. Only the data import filter needs to be adapted.


Flexibility


New data formats and sources can be added upon short notice.
