Le Hertzinno HZ-FA-QC est spécialisé Système d'inspection vocale de ligne de production conçu pour automatiser l'assurance qualité dans la fabrication . Utilisant une technologie avancée d'empreinte acoustique, le système capture les signaux audibles et ultrasoniques générés pendant le processus de production afin de créer une « identité acoustique » unique pour chaque produit. .

En comparant les signaux en temps réel à des modèles de référence appris par l'IA, le HZ-FA-QC détecte automatiquement les anomalies, les défauts ou les écarts de processus.

. Cette solution sans contact réduit considérablement le temps d'inspection manuelle et garantit une qualité de produit constante pour les machines tournantes et l'électronique grand public.

Fixed acoustic imaging for continuous online monitoring.

HZ-FA-371 captures audible and ultrasonic sound through a 128-channel MEMS microphone array. Acoustic imaging algorithms calculate the direction of sound sources and display the result as an acoustic image. The system can localize partial discharge, identify gas leak sources, estimate leak rate and stream data through industrial communication interfaces.

HOW IT WORKS

01

Sound Capture

128 MEMS microphones capture audible and ultrasonic sound signals from the monitored area.

02

Beamforming

AI beamforming algorithms suppress background noise and focus on target sound sources.

03

AI Acoustic Quality Inspection FAQ

Common questions about acoustic QC, voiceprint diagnostics and production-line inspection.

What is AI acoustic quality inspection?

AI acoustic quality inspection uses microphones, acoustic sensors and AI models to analyze the sound signature of a product during production. It helps detect abnormal noise, assembly defects and process deviations without physical contact.

What products are suitable for voiceprint quality inspection?

Typical targets include motors, bearings, gearboxes, pumps, fans, gas gauges, consumer electronics and rotating machinery that generate repeatable sound signatures during operation.

What is a Golden Sample?

A Golden Sample is a reference acoustic pattern collected from qualified products. The AI model learns this normal sound signature and compares real-time production signals against it.

Can HZ-FA-QC connect to production lines?

Yes. HZ-FA-QC is designed for production-line use and supports industrial integration such as PLC or MES workflows, depending on the project setup. The product page lists PLC/MES-related connectivity and instant alerts through I/O or Ethernet.

Does acoustic QC replace visual inspection?

Not always. Acoustic QC is best used to detect defects that create abnormal sound or vibration signatures. It can complement visual inspection, electrical testing and functional testing in a complete quality workflow.
