Abstract

PURPOSE:To announce overspeed to the driver and prevent traffic accident by comparing the speed of an automobile with the corresponding reference voltage, and generating alarming sounds. CONSTITUTION:The signal corresponding to speeds is obtained by a reed relay 2 incorporated into a speedometer 1 of an automobile, and this signal is applied to an integrating circuit 4 after waveform shaping 3. In the circuit 4, the input frequency is converted to voltage and the voltage corresponding to speeds is outputted. The output voltage of the circuit 4 and the voltage of a reference voltage circuit 7 to which the voltage corresponding to the speed beforehand set as desired is supplied are compared 5, 6. When the voltage corresponding to the speed of the automobile rises higher than the reference voltage, an oscillating amplifier circuit 8 operates, and a sounding body 9 is operated by the output thereof.
