The invention belongs to the technical field of vehicle safety, and particularly relates to a vehicle-mounted alcohol detection system. The system comprises a primary screening alcohol sensor and a fine screening alcohol sensor, the convenience and the accuracy of the vehicle-mounted alcohol detection system can be improved; three independent DC-DC power supply modules are designed; the DC-DC power supply module of the primary screening alcohol sensor supplies power to the DC-DC power supply module of the fine screening alcohol sensor, and the DC-DC power supply module supplies power to the processor MCU independently, so that the energy-saving and stable requirements of the vehicle-mounted alcohol detection system circuit can be better met.

    本发明属于车辆安全技术领域,尤其涉及一种车载酒精检测系统;包括初筛酒精传感器和精筛酒精传感器,可以提高车载酒精检测系统的便捷性和精确性,并且通过三个独立DC‑DC电源模块的设计,通过初筛酒精传感器的DC‑DC电源模块给精筛酒精传感器的DC‑DC电源模块供电,且通过DC‑DC电源模块为处理器MCU单独供电,可以更好满足车载酒精检测系统电路的节能、稳定的需求。
