DROWSY DRIVING DETECTOR AND A METHOD THEREOF CAPABLE OF JUDGING DROWSY DRIVING ACCORDING TO A PULSE SIGNAL BY DETECTING THE PULSE OF A DRIVER

摘要

PURPOSE: A drowsy driving detector and a method thereof are provided to judge drowsy driving exactly by sensing a pulse signal of a driver. ;CONSTITUTION: A drowsy driving detector contains: a sensing block(100) installed to a steering device of a vehicle, and radiating an infrared LED with driver's hands, and receiving reflected signals correspondingly to the luminous infrared LED, and then transmitting the value of a light receiving sensor; and a control block(200) receiving the transmitted value of the light receiving sensor and removing noise, and then abstracting a pulse signal, and comparing the value of the abstracted pulse signal with the preset datum value and judging the drowsy driving.;COPYRIGHT KIPO 2011
