Analysis of the measurement data: identifying NVH sources reliably
The core element of the Discom Software Suite: TasAlyser is the leading measurement application for analysis and live evaluation of acoustic and speed data in end-of-line testing. The software processes and analyzes the sensor data from the TAS frontend and displays it in real time as a graphic. This software accurately identifies NVH sources.
Quality monitoring in real time
The TasAlyser software is used for reliable monitoring of manufacturing quality in real time. The user is notified immediately of production faults and exceeding of defined limits by plain text rejection messages. This makes it possible to react to production faults immediately.
TasAlyser capabilities
- Sensor data processing: Order and frequency spectra, rotationally synchronous order analysis, level curves over rotational speed or torque, analysis of durability tests and individually configurable analysis modules
- Define limit values and test whether they are exceeded
- Acquisition of the serial number and other test specimen data
- Communication with test bench control: access status information, transmit analysis results
- Raw sensor signals available for listening and re-analysis
- Data storage and exchange with external analysis systems
Integration into the test bench via standardised interfaces
TasAlyser runs on the Discom PC rack directly in the control cabinets in the test bench. The analysis software uses a reliable, flexible and expandable communication protocol for the exchange of information with the test bench control unit. Widely used interfaces including Profibus, Profinet, CANbus, RS232 and UDP are available. For old test benches or try-out installations, the test runs can be controlled by automatic recognition of the test profile stages.
Your advantage: The hardware interfaces and communication protocols are well established in production.
Marvis: Detailed analysis and reporting
The “Marvis” software module analyzes and compares results in detail. It reads the result files generated by TasAlyser directly as files or from the results database. Marvis can also be used to generate printable reports with freely configurable layouts
Your advantage: Marvis provides detailed examinations of NVH sources and generates printable measurement reports ready for distribute.
Parameter database and network: Centralised management of test benches from an office PC
Discom measurement technology is designed for operation in production with a large number of test benches. TasAlyser manages all parameters for analysis, evaluation and limit value in one central parameter database. This database also contains the kinematics model of the test object, which makes it possible for TasAlyser to calculate the characteristic frequencies for each noise source. The database can manage multiple production lines and different models simultaneously. This makes it possible to parameterize test specimens centrally from a computer or server.
Your advantage: Management, parameterization and analysis can be performed centrally from an office PC without having to physically access test benches or servers.
Measurement data archive: Storage of results for decades
Every measurement analyzed by TasAlyser is stored. All measured values, curves, spectra, tracks and other results, including their limit values, are stored in result files (measurement archives). These files can be analyzed with the Discom Marvis software, sent via e-mail to colleagues or Discom experts and in the same time collected in the results database.
Your advantage: Complete production of multiple test benches can be stored for decades in this archive.
Wave recording: Listening to communcation
The original sensor data and rotational speed of each test run is recorded together with the test bench commands and the metadata in a wave data set in WAV format. These wave data sets can be replayed in TasAlyser, resulting in a virtual repeated test of the test object.
Your advantage: Wave recording can be used to optimize parameterization, test setup and limit value settings.
