Dynamic monitoring system for blind areas of vehicles

The utility model relates to a dynamic monitoring system for blind areas of vehicles. The dynamic monitoring system for blind areas is used for conducting real-time detection, dynamic analysis and acousto-optic alarming on vehicles in adjacent lanes and adjacent lane blind areas according to operating parameters and running states of the vehicles, road conditions and driving intentions of drivers, the monitoring system carries out dynamic adjustment on excitation signals of ultrasonic probes arranged on the two sides of each vehicle body so that different detection areas can be obtained, a signal preprocessing unit conducts signal-to-noise ratio assessment on weak barrier reflected wave signals received by the probes and conducts gain adjustment on signal amplification circuits in the probes so that echo signals with higher signal-to-noise ratios can be obtained, and related signals of sensors distributed on the vehicle bodies are processed through a master control framework and a slave control framework of the system so that the functions of quick detection, dynamic adjustment, target tracking, zone alarming and safety warning for blind areas can be achieved under different road conditions, different weather conditions and different driving conditions.
