Measurement system for capturing the sound emitted
by moving road vehicles according ISO 362.
Overview
Dynatrack is a special measurement system for capturing the sound emitted by moving road vehicles (Pass-by) and for determining the noise emitted by road vehicle tyres and exhausts on the basis of high-precision GNSS technology.
The Dynatack system is specifically designed to require only one operator for testing. With a user-friendly menu the Starpass software navigates the user through the individual test sequences. Via WiFi the data captured in the vehicle are already synchronized with the data measured by the base station during the measurement. Thus, the Pass-by measurement system allows the driver to evaluate all measurement results required for approval tests according to ISO 362:1998, 362 1-3:2015 and ISO 2001 / 43CE.
Properties:- Pass-by measurements including noise emitted by tyres and exhaust
- Positioning via GPS
- Data transmission via WiFi
- Sound and vibration measurement in the vehicle
- Controllable by one operator only
- OBD / CAN option
- Export of results to common data formats as Microsoft® Excel®, etc.
- Creation of reports
- Storage of raw data for post-processing
- High-precision GPS technology
- Acquisition of the vehicle location, speed and acceleration is realized with high-precision GNSS technology. The utilized receiver uses codes as well as phase signals to determine the vehicle location. As an option radar speed sensors and light barriers are available
- Efficient measurement
- The storage management of the Starpass software allows management of various vehicles with different technical specifications. For example, vehicles with different tyres may be tested and immediately compared while still in the car, which means significant time savings. Furthermore the user is able to define various test parameters, which he may combine with registered vehicles. GPS technology enables virtual arrangement of microphone positions as well as test zone entry and exit areas. This allows time-saving definition of several test zones, which may be combined with registered vehicles and test parameters. Pass-by extension for motorcycles
- A special, light-weight system extension has been developed and optimized to match the more demanding requirements of motorcycles.
