The invention provides a detection method and system for preventing drunk driving. The method comprises the following steps: an association relationship among a vehicle, a driver and a handheld terminal is created in a cloud server; a handheld terminal reports positioning information to the cloud server at regular time; after the vehicle-mounted system receives the starting instruction and verifies the identity of the driver, the cloud server acquires positioning information reported by a handheld terminal corresponding to the driver within a first time length in the past according to the incidence relation and sends the positioning information to the vehicle-mounted system; a vehicle-mounted system extracts staying positioning points of the driver and judges whether the staying positioning points belong to risk positioning points or not; if so, the current head portrait information is acquired and the current head portrait information is input into a drinking identification model; ifit is recognized that the driver drinks the alcohol, the driver is reminded to use a preset alcohol detector to detect the alcohol content. The vehicle is prohibited from being started under the condition that a driver is confirmed to drink, interference of other people in the vehicle can be shielded, advanced detection is adopted, the detection range is gradually narrowed, the detection accuracyis improved, and the effectiveness of a detection result is guaranteed.
本发明提供预防酒驾的检测方法及其系统,方法包括:在云端服务器创建车辆、驾驶员和手持终端的关联关系;手持终端定时上报定位信息至云端服务器;车载系统接收到启动指令后,验证驾驶员的身份通过后,云端服务器依据关联关系获取驾驶员对应的手持终端在过去第一时长内上报的定位信息并发送至车载系统;车载系统提取驾驶员的逗留定位点,判断是否属于风险定位点;若是,则获取将所述当前头像信息输入至饮酒识别模型;若识别为饮酒,则提示驾驶员使用预置的酒精检测仪进行酒精含量检测。本发明在确认驾驶员饮酒的情况下禁止车辆启动,能屏蔽车内其他人的干扰,采用进阶式检测,逐步缩小检测范围和提高检测精准度,保证检测结果的有效性。
