DISPOSITIVO Y PROCEDIMIENTO PARA DETECTAR LA PRESENCIA DE UN VEHICULO EN UNA PLAZA DE APARCAMIENTO.

摘要

The present invention relates to a device for detecting the presence of a vehicle in a parking space which in addition to signaling means for signaling the presence of a vehicle also comprises optical emitting means and corresponding optical detecting means; processing means for processing the optical signal detected to obtain a first train of pulses x[n] the amplitude of which is proportional to the distance between the device and the target or the floor; a statistical unit comprising a plurality of registers for storing the amplitude values of a predetermined number of consecutive pulses obtained and calculating means for calculating a statistical function with the value from said registers; and a verifying unit evaluating whether the result of the statistical function is above a target threshold value (umbB) during a predetermined time period to trigger an activation signal for activating the signaling means.
