Problems solved by technology

[0003] The alcohol detection methods in the prior art do not consider the influence of the wind speed outside the car and the wind speed inside the car on the alcohol detection value. In fact, whether opening the window or turning on the air conditioner in the car will accelerate the air flow in the car. Furthermore, it has a great impact on the alcohol detection in the driving position. At this time, it is unreasonable to use the threshold for judging drunk driving set in the windless state to judge whether drunk driving

Embodiment Construction

[0025] Contents of the technical plan

[0026] 1 overall system architecture design

[0027] The autonomous reminder system for multi-point detection drunk driving vehicles is mainly composed of a vehicle condition judgment module, a control module, an alcohol concentration detection module, and an alarm reminder module. The vehicle condition judgment module is composed of a vehicle window opening detection module, a wind speed detection module outside the vehicle, and an air conditioner wind speed detection module. The alarm reminder module is composed of a liquid crystal display reminder module, a voice reminder module, a speed limit module, a green light reminder module, and an upload location module.

[0028] Window opening detectors are installed in the car, and alcohol concentration detectors are installed on the seat backs directly in front of the driver, co-pilot, and rear passengers. Install the outside wind speed detection module on the outside of the four windows....

Abstract

The invention provides a drunk driving alarm method. In the method, an alarm and prompt module is controlled to operate according to a car window opening value, an extra-car wind speed value, an intra-car wind speed value and an alcohol concentration value of each seat. On one hand, a drunk driving judgment threshold value is corrected constantly according to the intra-car wind speed and the extra-car wind speed, so that a drunk driving judgment result is more accurate and more reasonable; on the other hand, a drunk driving alarm system can give three stages of alarms, so that different alarm measures are taken for drunk driving at different degrees.

Description

technical field [0001] The invention relates to the field of drunk driving detection, in particular to the field of alcohol concentration detection inside the car considering the influence of wind speed inside the car and outside the car. Background technique [0002] At present, there are multiple anti-drinking driving technologies at home and abroad. For example, "alcohol lock", "alcohol detector", "anti-drunk driving mobile phone", "laser detection" and so on in foreign countries, the common ones in China are "drunk stop" and traffic police drunk driving tester. The "drunk stop" system can fundamentally eliminate drunk driving and prevent problems before they happen, but there are still many disadvantages, such as blindly stopping when it is impossible to distinguish whether the passenger is drinking or the driver is drinking, the driver is drinking and finds someone to test the car Normal start but no remedial measures, driver drinking unconsciousness damage brake stop ...
