MONITORING APPARATUS FOR PROTECTING DRIVERS FROM CRIMES BY DETECTING APPROACHING PERSONS

摘要

PURPOSE: A monitoring apparatus for protecting drivers is provided to protect the driver from a crime by alarming when a person approaches. CONSTITUTION: A monitoring apparatus for protecting drivers includes an infrared transmitter(101), a sensor driver(102), an infrared receiver(103), an amplifier(104), and A/D converter(105), a controller(106), an alarm driver(107), and a power source(108). The infrared transmitter radiates an infrared ray to surroundings of a car. The sensor driver operates the infrared transmitter under a control of the controller. The infrared receiver receives an infrared reflected from a man approaching the car. The amplifier amplifies the received infrared. The controller determines whether an approaching person exists based on a signal from the A/D converter.
