Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a parking management system and particularly to a system for parking management that employs unique Optical Code Division Multiple Access (OCDMA) technology.
Description of Related Art
[002] With the increasing number of vehicles, efficient parking management and enhanced security for parked vehicles have become challenging. The parking of vehicles is especially challenging in crowded areas or areas with less spaces.
[003] Conventional parking systems often lack real-time monitoring, precise parking validation, and an immediate alerts system for unauthorized access of vehicle by any person. The conventional parking systems rely on manual process or basic sensors which are incapable of addressing parking challenges. The challenges associated with parking management and vehicle security have been addressed by various inventions but often fail to address the precise parking validation enhanced security and real time monitoring and are prone to errors.
[004] There are many systems that have been developed to address a vehicle theft problems. These anti-theft systems mainly include Global Positioning System (GPS) trackers and alarm systems that activate only after the vehicle has been moved. However, these anti-theft systems do not recognize incorrect parking of the vehicle and also fail to transmit autonomous alerts in case an unwanted movement or positioning of the vehicle is recognized.
[005] There is thus a need for an improved and advanced parking management system that can administer the aforementioned limitations in a more efficient manner.
