Abstract
PURPOSE: To prevent a driver from driving a car at dozing off by a method wherein alarm sound is generated at a predetermined interval and a driver must give a confirming voice to the alarm, and louder alarm will be sounded to wake the drive up it a confirming reply by the driver is not avilable.
CONSTITUTION: With the predetermined signal period T adjusted by a variable resistor 12 in the first alarm circuit 10, the variable periodical signal generator 11 generates the signal voltage V, and every time the voltage is generated, the gate circuit 14 is picked and the speaker 15 sounds an alarm in response to the output signal from the alarm signal generator 13. At the same time, accompanied with rising of the signal voltage V, the FF circuit 51 is set and gate input signal A is generated. If this condition continues, inverter 43 is actuated at the time the voltage V terminates, then the speaker 15 sounds through the alarm signal transmitter 41 of the second alarm circuit 40. But if a confirming reply voice is available while the voltage V is generated, the FF circuit 51 is reset through voice detecting circuit 20, thereby intercepting alarm sound generation.
