Method and device for detecting presence of vehicle in parking space

摘要

A method for notifying a user of the status of a parking space. The method comprises transmitting a pulse from a transceiver assigned to a parking space and for each pulse receiving by transceiver a corresponding echo created by said pulse being reflecting back from a object occupying said parking space. The method further comprises measuring corresponding echo time by a processing unit. The method further comprises comparing said corresponding echo time to a predefined range of echo times by a processing unit to determine occupancy of said parking space. The method further comprises using said occupancy of parking space to determine the parking space status by a processing unit, together with information on time of day and parking space permission. The method further comprises notifying a user of said parking space status by visual indication from at least one light emitting diode array.

1. A method for notifying at least one user of the status of a plurality of parking spaces, comprising:
transmitting at least one pulse from each of a plurality of transceivers, wherein each of said plurality of transceivers is located on an opposing side of a device housing and angled at a trajectory towards one of a plurality of parking spaces, and for each pulse:
receiving by respective transceiver a corresponding echo created by said pulse being reflecting back from at least one object occupying respective said parking space;measuring corresponding echo time by at least one processing unit;comparing said corresponding echo time to a predefined range of echo times by at least one processing unit to determine occupancy of respective said parking space;using said occupancy of respective said parking space to determine the status of respective said parking space by at least one processing unit, together with information on time of day and parking space permission; andnotifying at least one user of respective said parking space status by visual indication from a plurality of respective light emitting diode arrays.
