Controller Analyser
Do you want to control the vibration phenomena and propagation of sound?
Industrial companies, laboratories, research centers, acousticians, technical schools, are you looking for a solution that would allow you to combat noise, vibration … Our controller analyzer meets your expectations.
Based on a 32-bit floating-point DSP, the Quietys controller can achieve 2 Gflops peak performance when the SIMD architecture is implemented.
With a modular design, the Quietys controller includes 6 inputs and 4 outputs that can be individually enabled and configured to match your needs. Data conversion and filtering stages are optimized to provide a true real-time system able to respond to any change in input signals.
The Quietys controller comprises of a serial connection, using a proprietary Graphical User Interface, which allows a controller piloting and above all data collection. With this GUI you analyze the action of the controller and evaluate its results. This serial link can also be used to update the firmware of the controller (software updating) and trace information maintenance.
Based on high-tech technology, it is both a counter-signal generator and a data analyzer. It provides innovative opportunities to deal with low frequencies.
Quietys proposes controllers with or without electroacoustic material, leaving you the opportunity to use your own devices (subject to compatibility, contact us).
You can choose the system that suits you, ie:
- Either a “ready to use” preset anti-noise controller without GUI,
- Or a controller analyzer to adapt and implement different configurations (number of inputs, outputs, frequency sampling, … customizable).
Case Studies
The Quietys controller is able to analyse received signals regardless of their nature. The 2 situations here below will make it clear:
Case 1: Treatment of acoustic signals, noise reduction
The device usesnthe Quietys controller coupled with microphones and speakers specially developed for performing in the lower frequencies. Treatment can be performed:
The results obtained are compelling, the device greatly lessens noise which reduces stress, fatigue ….
Case 2: Treatment of vibration signals, reducing solid vibrations
A scientific and technological feasibility study was conducted in collaboration with a technology transfer center to highlight the relevance of a solution that would alleviate pressure fluctuations of hydraulic pipes.
The system comprises of one Quietys controller analyzer coupled with 5 piezoelectric ceramic rings, a hybrid feedback/feedforward active noise control algorithm and two downstream pressure signal controls. The results obtained are persuasive.
