Abstract:
A voice warning system for automobiles comprising:a microprocessor,a first voice integrated circuit;a second voice integrated circuit;a power input;a voltage regulator;an engine oil indicator lamp sensing interface;a third stage lock sensing interface;a reset circuit;a time base oscillator;a mixer;a volume control;an amplifier;a loudspeaker;a quieting circuit;an engine speed sensor;an engine speed sensing interface;a ripple differential amplifier;a window comparator;an engine speed sensing adjustment;a door positive sensing interface;a door negative sensing interface;a hand brake sensing interface;an engine oil sensing interface;an engine temperature sensor;an high-low temperature selection;a gasoline sensing interface;a LCD module;a brake oil level detector;an engine oil mileage interface;an automatic transmission fluid mileage interface;a battery; anda power detector;whereby when a voltage of 12 V is applied to said power input, the voltage will be regulated by said voltage regulator to a voltage for supplying power to all circuits; when an automobile is not started, said engine oil indicator lamp sensing interface is at LOW condition and said third stage lock sensing interface is also at LOW condition; when the automobile is started, these two interfaces will be at HI condition and meanwhile said power input is already supplied with a voltage which is regulated by said voltage regulator to a voltage of 5V for supplying voltage to all circuits; when the voltage rises from 0 to 5V said reset circuit will send out a reset pulse signal to said microprocessor for resetting its condition and said time base oscillator begins to generate a time base of 3.58 MHZ and provide it to said microprocessor; after a time delay of
