1、 Background Overview
Vehicle Acousto-optic Warning Device， Vehicle sound and light alarm device is an important safety device for automobiles. In emergency situations, such as vehicle malfunctions, collision risks, or the need for emergency parking, the device will automatically trigger, emitting a piercing alarm sound and striking flashes to attract the driver's attention, aiming to remind the driver through sound and light signals to improve driving safety.
The active safety ADAS testing conducted by testing agencies such as CNCAP, ENCAP, and NHTSA typically includes multiple aspects, such as testing of auxiliary driving functions such as automatic emergency braking system (AEB), forward collision warning system (FCW), lane keeping assistance system (LKA), etc. These tests aim to simulate diverse, complex, and dangerous operating conditions to evaluate the ability of ADAS systems to alert drivers or control vehicles, thereby avoiding traffic accidents and protecting occupants and external traffic participants.
The vehicle sound and light alarm system usually includes components such as sound and light prompt modules, sensors, microprocessors, etc. These components detect specific triggering signals (such as approaching obstacles, exceeding speed limits, etc.) and emit sound and light alarm signals to alert drivers or surrounding personnel to potential dangers. It is of great significance for enterprises to develop sound and light alarm devices and verify whether ADAS functions meet relevant regulatory requirements by accurately and low latency collecting alarm signals emitted by vehicles to verify their ADAS functions.
2、 ZR-TLOG-ASD3 Sound and Light Image Alarm Testing System
The TLOG-ASD3 sound and light image alarm system is a reliable and powerful data acquisition module used to detect interior alarm prompt information, including sound, steering wheel vibration, instrument panel icons, and light alarm signals. Adopting high-performance cameras, microphones, and vibration sensors, with high-quality sound and image processors. Millisecond level response to various alarm signals, easy operation, convenient and efficient system configuration, used to detect relevant alarm signals of vehicle ADAS functions, such as AEB, LDW, FCW, BSD and other alarm signals.
The sound and light image alarm testing system consists of an alarm signal acquisition module, vibration sensor, image sensor, microphone, lighting sensor, and fixture, etc. It can achieve highly automated alarm signal recognition and acquisition, with a delay of less than 5ms for sound and light signal acquisition and less than 15ms for image signal recognition.
The advantages of this audio-visual image alarm testing system are:
1. Millisecond level response to various alarm signals
2. Easy operation and convenient system configuration
3. The measurement configuration file can be saved at any time and reloaded later
4. Support network communication and CAN communication functions
3、 Quickly conduct experiments using ZR-TLOG-ADS3
Install alarm signal collection sensors on the test vehicle, such as cameras, microphones, lighting sensors, and steering wheel vibration sensors, to collect vehicle alarm signals when the relevant ADAS functions of the vehicle are triggered; Used for the validation and development of related ADAS functions such as AEB, ELK, FCW, etc.
Vehicle sound and light alarm device plays a crucial role in modern transportation. It can not only provide timely warnings in emergency situations, but also play a role in preventing accidents during daily driving.
The ZR-TLOG-ASD3 sound and light alarm acquisition device can meet the ADAS functions of various vehicle enterprises, such as AEB, FCW, ELK, etc., for development and verification. On the other hand, it can also be used for regulatory testing of vehicles by inspection agencies, such as CNCAP, ENCAP, and I-VISTA.
