The invention discloses a vehicle-mounted alcohol detection device which comprises a sweat alcohol detector, an air alcohol detector, a central processing unit and a relay, the relay is electrically connected with an automobile ignition starting circuit; the sweat alcohol detector is arranged on an automobile steering wheel in a sleeving mode and provided with a sweat collecting groove, a sweat sensor, a sweat alcohol concentration data processor, a signal conditioning circuit and a power source. The air alcohol detector is arranged on an automobile steering wheel; the air alcohol detector is provided with an collection port, a gas sensor, a gas alcohol concentration data processor, a signal conditioning circuit and a power supply. The alcohol detection device has the advantages that when a driver enters a vehicle, holds a steering wheel and exhales, the accurate alcohol content is obtained through data processing and analysis, whether the driver drinks or not is effectively judged and detected, a vehicle-mounted ignition starting circuit can be cut off through a relay, the vehicle cannot be started, and therefore the potential safety hazard of drunk driving is reduced.

    本发明公开一种车载酒精检测装置,包括汗液酒精检测仪、空气酒精检测仪、中央处理器和继电器;继电器电性连接汽车点火启动电路;汗液酒精检测仪套设在汽车方向盘上,汗液酒精检测仪设有汗液收集槽、汗液传感器、汗液酒精浓度数据处理器、信号调理电路以及电源;空气酒精检测仪设在汽车方向盘上;空气酒精检测仪上设有采集口、气体传感器、气体酒精浓度数据处理器、信号调理电路以及电源。本发明的有益效果:当驾驶员进入车内并握住方向盘以及呼气时,通过数据处理分析得到准确的酒精含量,有效判断检测驾驶员是否饮酒并且能够通过继电器切断车载点火启动电路,使汽车无法发动,以此来减少酒驾的安全隐患。
