The invention discloses a vehicle-mounted alcohol detection control system based on a switching power source controller. The vehicle-mounted alcohol detection control system comprises an alcohol sensor, a conditioning amplification circuit, a filter circuit, an analog-digital conversion module, a microcontroller module, an ignition control device, a display module, a key set module, a monitoring reset module, a sound-light alarm module, a JTAG interface module, a power supply module and a voltage conversion circuit. The ultra-high sensitivity alcohol sensor, an ultra-low power consumption single-chip microcomputer system and a method for automatically detecting alcohol concentration are adopted, and a driver can be prevented from avoiding detection so that whether the driver is in drunk driving or not can be judged.
