he wiper potentiometer potentiometer RPl increases. When the potential rise to l.6V, ICl TWH8778 power switching device is turned on, the IC2 IC TM801 voice work, which outputs the integrated amplifier IC3 LM386 were pushing the power amplifier speaker BLl alarm. At the same time, the relay J1 was electric action, its break contact off, cut off vehicle ignition circuit, forcing the engine stall, the driver to control drunken driving purposes.
