SigMA
Production Quality Test System
SigMA is a smart real-time quality test system based on machine hearing technology for reliable inline and end-of-line qualification tests. It supports signal input of 8 or more channels. Sound and vibration signals togther with the tacho signal are analyzed to objectively assess the test object's NVH performance, acting as a safeguard of the quality of outgoing products.
Comprehensive Quality Control
The powerful system supports quality evaluation based on multiple indicators, including conventional one-dimensional (1D) time domain, frequency domain, and angular domain indicators; two-dimensional (2D) time domain, frequency domain, and angular domain indicators, color map and other indicators; as well as more powerful functions as shaft synchronous analysis.
Intelligent Defect Localization
With powerful functions and strong analytical capabilities, SigMA effectively intercepts products, which sound and vibration quality do not meet the predetermined requirements, from flowing into the market, helps engineers to quickly locate defective components for convenient and fast repairs, as well as to analyse the root cause of failures, ensuring the quality while enabling a systematic approach to quality assurance.
Fully Automated Tests and Real-time Evaluation
SigMA is able to communicate with test benches and operate unmanned. Communication modes include HTTP protocol, TCP protocol, serial communication, CAN bus, etc.
Big Data for Trend Prediction
Quality management is not just about passively eliminating defective products. SigMA saves the acoustic fingerprints and test data of each product, which allows engineers to conduct big data analysis to predict the quality trend of product batches and resolve structural quality problems.
Original Sound Playback
Abnormalies are sometimes transient and may not necessarily recur. Yet they are by no means neglibigle. With SigMA's denoising and playback features, engineers are now able to to replay the original track and replicate test conditions for subjective and qualitative evaluations.
B/S Software Architecture
Users can now conveniently view real-time and historical data through the browsers on their laptops, mobile phones or tablets using local area networks (LAN) or servers.
