IPC: G06Q50/10
Filed: 1993-03-26
Abstract: PURPOSE:To confirm empty car sections in a parking lot at an optional position and even in the dim illumination and to enable a smooth flow of cars to satisfy the users by detecting a parking car or an empty car by the sensors provided on each section of the parking lot and then displaying the parking car or the empty car on a display panel of each parking section. CONSTITUTION:A car entering a parking lot through its entrance 21 confirm an empty car section by an empty car display panel 7 installed on each parking section 4 in a parking lot and parks the car. When the car is parked in the empty car section, the ultrasonic waves are emitted to the front or rear part of the parked car from a reflection type ultrasonic sensor 6 installed horizontally to the car. Thus this parking section 4 is confirmed when the reflected ultrasonic wores from the car are sensed by the sensor 6, and the display of the panel 7 is changed to a parking car from an empty car to let the subsequent cars know this fact. It is desirable to use a polyhedron display plate consisting of plural display screens. Thus it is possible to confirm the empty sections 4 even at an optional position including the entrance 21 and flow of cars becomes smooth.
