Application

The passing noise test system is used to measure the noise outside the vehicle during acceleration. It can meet ECE R51, GB1495-2018 and GB1495-2002 at the same time. The equipment function, range and accuracy can be applied to all models, and the operation is convenient and efficient.

●Test items

Accelerated test: GB1495-2018, GB1495-2002, ECE R51-2015

Uniform speed test: GB1495-2018, GB1495-2002, ECE R51-2015

●Measurement parameters

Vehicle speed, time, distance, acceleration, engine speed, sound level, meteorological parameters (temperature, wind speed).

●Main Features

Support calibration: support sensor calibration, test data management

The parameters can be set: the vehicle length, reference point, trigger distance of the access line, etc. can be set by the noise test system outside the vehicle

Print report: The test system can print the test results on site and generate test reports.

Flexible configuration: Flexible configuration of test plan, you can choose unilateral round-trip test and bilateral round-trip test mode

Easy to operate: the hardware is automatically triggered at the beginning and end of the test, with small delay, voice prompts, and convenient operation

Applicable models: Meet ECE R51 Appendix 10 Method B and GB 1495-2002 Method A to measure the noise outside the vehicle during acceleration, applicable to all models

Laser trigger: laser trigger sensor trigger, stable and reliable; RTK base station can also be configured, automatic position trigger, no laser trigger sensor is required

Real-time measurement: real-time measurement and calculation of sound pressure level, vehicle speed, engine speed, acceleration time, acceleration distance, average acceleration of the test area and other signals

Support optional: optional environmental temperature, surface temperature sensor and wind speed sensor, etc., real-time weather data measurement
