AVAS Test System MSZ ZR-TLOG-AVAS

Overview

This system is specifically designed for automated testing in compliance with the R138 standard. The system enables real-time data collection and transmission to an application computer via networking. The software analyzes and processes data in real-time. Key components include dedicated microphone sensors, an acoustic signal processing box, a driver-assist display, a comprehensive data acquisition module, and a dual-antenna GPS. All components are connected via LEMO connectors to ensure stable and reliable data transmission. The computer communicates with the data acquisition host in real-time. Through optimized testing procedures, the system simplifies operations and automatically executes test protocols after calibration, eliminating manual intervention and minimizing human impact on test results

The ZR-TLOG-AVAS vehicle ride comfort testing system includes a data acquisition host, driver display, remote control handle, sound acquisition box, microphones, WiFi communication bridge, and PC data processing softwar
