SignalLAB
is a comprehensive tool for analysing signals
particularly concerning testing laboratories
It enables us to understand the behaviour
of a product in its environment by characterizing
the mechanical aspects and sound perception.
It includes modules and a business acquisition
module:
- Modulus of time-frequency
analysis
- Module Chocs Module
Shocks
- Module de Personnalisation
d’Essais Mécaniques Module
Customization Mechanical Test
- Module de Classification
Classification Module
- Module d'acquisition
Acquisition Module
- Module d'automation
Automation Module
SignalLAB runs on Microsoft Windows NT version
4.0., Windows 2000 and Windows XP. Une mémoire
vive de 1 Go est conseillée (512 Mo
minimum). A RAM 1 GB is recommended (512 MB
minimum).

 Base
module
The basic module is
required to use the modules trades. =It
provides the user with tools for data
management, signal processing and visualization
powerful and easier to use. The signals
used by SignalLAB come from the acquisition
module or import data files from the import
many functions available (format embeddable
customer at the request). Data management
is graphic and tree. A wide selection
of the important functions of signal processing
and statistics are available. A calculator
allows signals to perform simple or complex
functions. SignalLAB also lets users launch
functions written in Matlab or C + + with
a Man Machine Interface very simple.

Modulus
of time-frequency analysis
It allows users to
SignalLAB to obtain spectral image complete
as possible of their signals. It includes
original functions and user-friendly filter
in the time-frequency plane.
- Labeling signals
- Spectrogram
simple and reallocated
- Pseudo
City Transformed Wigner (PWV)
- Transformed
by wavelets of Morlet and orthogonal wavelets
-
Filtering on time-frequency spectrogram,
signal synthesis time equivalent
-
Time-frequency filtering on wavelets of
Morlet, signal synthesis time equivalent
- Curves

Module Shocks
It allows the calculation
of the response spectra of shock. It offers
new features for detecting defects measuring
and identifying patterns own record in a clash.
- Calculating
response spectrum methods shocks by Prony
- Extraction modes
own
- Calculating response
spectrum shocks FFT
- Automatic verification
of the quality measures: offset, drift
with an accelerometer, sub-quantification,
sub-sampling, saturation

Module
Customization Mechanical Test
t integrates functions
conventional calculation of mechanical damage,
but also the workshop of customizations test
the fullest and most innovative market. A
unique feature makes it possible to identify
and date the constraint on the origin of the
mechanical damage the most important.
- Functions calculation
of damage and fatigue equivalent extraction
peaks / valleys, counting RainFlow, Mix,
calculation of damage, viewing time -
frequency of the damage, test specification
sinuses, filtering in the matrix synthesis
and Rainflow reverse signal peak-valley
- Personalize statistical
test (spectral approach), specification
of DSP Test
- Personalize deterministic
test (temporal approach), specification
of DSP Test

Classification
Module
It includes many automation
to promote the learning and recognition
of interesting features within large amounts
of data. It is particularly suited to
correlate subjective - objective.
- Labeling signals
- Specification graphical
features classification or select from
existing ones
- Choosing among several
methods of learning supervised or unsupervised
- Numerous possibilities
for automating the classification on
lists of directories

Acquisition
Module
It includes a multi-purpose
function signal acquisition capable of driving
a representative selection of maps of acquisition.
This module integrates functions for viewing
and export. It can be used independently
of the core module.
|
|
|
|
Automation
Module
It allows you to implement
a chain of treatment in an automatic way to
a set of files across multiple directories.
This ensures quality control of a tabulation
that it is repetitive in its implementation
or in the management of successive versions.
