Large-area parking-monitoring system
View Patent ↗The present invention discloses a large-area parking-monitoring system. It comprises a plurality of smart-phone-like parking-monitoring devices. Each device monitors multiple parking spaces. The acquired parking occupancy data are transmitted to a parking-management server using cellular communication. The present invention takes advantage of the existing city-wide cellular network and therefore, can monitor parking city-wide at low cost.
1. A large-area parking-monitoring system comprising:
a first parking-monitoring device comprising a first image-capturing module for capturing first images of a first plurality of parking spaces, a first image processor for processing said first images to generate first parking occupancy data for said first plurality of parking spaces, and a first cellular communication module for transmitting said first parking occupancy data at a first pre-determined interval;
a second parking-monitoring device comprising a second image-capturing module for capturing second images of a second plurality of parking spaces, a second image processor for processing said second images to generate second parking occupancy data for said second plurality of parking spaces, and a second cellular communication module for transmitting said second parking occupancy data at a second pre-determined interval;
wherein said first and second cellular communication modules share the same cellular subscriber identity.
2. The large-area parking-monitoring system according to claim 1 , wherein said first and second parking-monitoring devices are configured to transmit parking occupancy data alternately.
3. The large-area parking-monitoring system according to claim 1 , wherein said first and second parking-monitoring devices are configured to transmit parking occupancy data at different times.
4. The large-area parking-monitoring system according to claim 1 , wherein said first image-capturing module, said first image processor and said first cellular communication module are located in a first housing.
5. The large-area parking-monitoring system according to claim 1 , wherein said second image-capturing module, said second image processor and said second cellular communication module are located in a second housing.
6. The large-area parking-monitoring system according to claim 1 , wherein selected one of said first and second parking-monitoring devices is mounted on a support in a street.
7. The large-area parking-monitoring system according to claim 6 , wherein said support provides power to said selected parking-monitoring device.
8. The large-area parking-monitoring system according to claim 1 , wherein selected one of said first and second image-capturing modules comprises a plurality of cameras facing different directions.
9. The large-area parking-monitoring system according to claim 1 , further comprising a memory for storing a smart-phone operating system.
10. The large-area parking-monitoring system according to claim 9 , wherein said memory further stores an image-recognition app.
11. The large-area parking-monitoring system according to claim 1 , further comprising a parking-management server for receiving and managing said first and second parking occupancy data.
12. The large-area parking-monitoring system according to claim 11 , wherein a motorist retrieves selected one of said first and second parking occupancy data from said parking-management server.
