The invention discloses a drunk driving controller, and belongs to the technical field of control equipment manufacturing. The drunk driving controller is composed of a control box, a blowing cavity, an alcohol sensor R1 and a pneumatic switch K1. The pneumatic switch K1 and the alcohol sensor R1 are installed inside the blowing cavity. A current limiting resistor R2, a controllable switch relay J, an ignition coil L1 and a power source are installed inside the control box. The controllable switch relay J is provided with normally open contacts a-c. The contact c is connected with the positive electrode of the power source, and the contact a is connected with the ignition coil L1. The other end of the ignition coil L1 is connected with the negative electrode of the power source. When a driver starts an automobile, due to the fact that the contacts a-c are disconnected, the ignition coil cannot be powered to perform ignition; during ignition, air needs to be blown into the blowing cavity to turn off the pneumatic switch K1; at the moment, air in the mouth of the driver is blown through the alcohol sensor R1; if the driver is drunk, the resistance of the alcohol sensor R1 becomes smaller, and the voltage of the two ends of the controllable switch relay J is low and is not enough to turn on the controllable switch relay J; the normally open contacts a-c are in the turn-off state, the ignition coil L1 cannot be powered to perform ignition, and the automobile cannot be started; otherwise, the ignition coil L1 is powered to perform ignition.
