Abstract
Aspects of the present disclosure describe distributed fiber optic sensing (DFOS) systems, methods, and structures that advantageously are employed in smart stadium or other venue applications, such applications including: parking lot security and management; intrusion detection; social sensing; air quality monitoring and early fire detection—among others.
Claims7
A distributed fiber optic sensing (DFOS) system for parking lot monitoring and control, said system comprising:
- a length optical fiber cable installed throughout selected areas of the parking lot;
- a DFOS interrogator system in optical communication with the optical fiber cable;
- and
- an intelligent analyzer configured to analyze DFOS sensing data received by the DFOS interrogator system, said analyzer configured to track vehicles entering and track vehicles exiting the parking lot and provide occupancy detection and parking hours monitoring for individual parking spaces in the parking lot from the analyzed sensing data.
