不停车酒驾检测系统和酒驾检测方法
By using lasers of different wavelengths to detect alcohol concentration in different window states of a vehicle, the problem of needing to stop for drunk driving detection has been solved, achieving high-precision and high-reliability non-stop drunk driving detection while taking into account both window shading film and passenger safety.

AI Technical Summary
Current drunk driving detection technology requires drivers to stop for testing, which leads to increased traffic disruption and congestion, and the accuracy and reliability of the detection are difficult to guarantee.
An alcohol gas concentration detection device based on lasers of different wavelengths is used to detect the alcohol gas concentration in different window opening states in the vehicle cabin. By setting lasers of the first, second, and third wavelengths, respectively, it is used for scenarios where windows in the same row of the vehicle are open, one window is open and one is closed, and both windows are closed. By combining the laser frequency and power configuration, the detection accuracy and reliability are improved.
It enables non-stop drunk driving detection, improves detection accuracy and reliability, takes into account the impact of window shading film on passenger and driving safety, and avoids the crashing of high-power lasers.
