ASec fault alarm and status signal audio and video extraction system
ASec (Alarm Signal Extraction in Cabin) fault alarm and status signal audio and video extraction system is used to extract fault and status signals and sound alarm signals on the dashboard or central control large screen, and extract relevant information through video and audio respectively. ASec can also realize functions such as bus acquisition, signal analysis, information comparison, information forwarding, and signal generation.
The ASec function currently has two parts:
ASec-Video Analysis visual alarm signal extraction function, by pre-analyzing the brightness, grayscale and hue of the fault or state trigger mark in the instrument panel or the central control large screen area, when it recognizes the visual alarm signal that meets the preset threshold , extract it and convert it into a bus signal to output to the specified device.
ASec-Audio Analysis The audio alarm signal extraction function can analyze the audio frequency spectrum of the audio alarm signal in the vehicle cabin in advance. After the system recognizes the peak point in this frequency band, it will be used as the trigger condition value of the audio alarm signal.
The system has the following characteristics:
High recognition rate and low latency
Configurable and customizable
Lightweight
High degree of recognition automation
Support CAN output
The main applications of the system include:
ADAS function benchmarking
open road test
Proving ground performance test
Automatic driving status monitoring
