Abstract

A parking control system includes a cloud server, a sensor coupled to a parking spot, and a mobile robot device. The sensor detects a vehicle entering the parking spot, and transmits a first signal to the cloud server. The cloud server, upon reception of the first signal, records an entry time of the vehicle, and dispatches the mobile robot device to the parking spot. The mobile robot device captures identification information of the vehicle by a camera, and transmits a second signal including the identification information to the cloud server. The sensor detects the vehicle exiting the parking spot, and transmits a third signal to the cloud server. The cloud server, upon reception of the third signal, records an exit time of the vehicle. The cloud server calculates a parking duration between the entry time and the exit time, and determines whether the parking duration has exceeded a predetermined duration.

First claim

What is claimed is:

1. A parking control method, comprising:
detecting, by a sensor coupled to and physically installed on a parking spot in a parking lot, a vehicle entering the parking spot;
transmitting, by the sensor and to a cloud server, a first wireless signal;
recording, by the cloud server upon reception of the first wireless signal, an entry time of the vehicle;
dispatching, by the cloud server, a mobile robot device to the parking spot;
communicating between the mobile robot device and the sensor while the mobile robot device is dispatched to the parking spot;
capturing, by the mobile robot device, identification information of the vehicle using a camera;
transmitting, by the mobile robot device and to the cloud server, a second wireless signal including the identification information of the vehicle;
detecting, by the sensor, the vehicle exiting the parking spot;
transmitting, by the sensor and to the cloud server, a third wireless signal;
recording, by the cloud server upon reception of the third wireless signal, an exit time of the vehicle;
calculating, by the cloud server, a parking duration between the entry time and the exit time; and
determining, based on the identification information and the parking duration, whether the parking duration has exceeded a predetermined duration.

2. The parking control method according to claim 1 , further comprising:
calculating, by the cloud server and before receiving the third wireless signal, a balance time based on the entry time and the predetermined duration; and
sending, by the cloud server, a first notification to an operator of the vehicle when the balance time is less than a threshold.

3. The parking control method according to claim 1 , further comprising:
sending, by the cloud server, a second notification to an operator of the vehicle when the parking duration has exceeded the predetermined duration.

4. The parking control method according to claim 1 , further comprising:
navigating, by the mobile robot device, a map of the parking lot to arrive at the parking spot.

5. The parking control method according to claim 1 ,
wherein, when the mobile robot device is dispatched to a plurality of parking spots, the mobile robot device captures the identification information of the vehicle of each of the plurality of parking spots one after another.

6. The parking control method according to claim 1 , wherein the mobile robot device returns to a docking station after transmitting the second wireless signal.

7. The parking control method according to claim 1 , wherein the identification information comprises a license plate number of the vehicle.

8. The parking control method according to claim 1 , wherein the sensor is an ultrasonic sensor.

9. The parking control method according to claim 1 , further comprising:
determining, by the cloud server and upon reception of the second wireless signal, whether the vehicle is authorized to park in the parking spot based on the identification information; and
sending, by the cloud server, a third notification to an operator of the vehicle if the vehicle is not authorized.

10. A parking control system, comprising:
a cloud server coupled to a transceiver;
a sensor comprising a sensing circuit and a transmitter, wherein the sensor is coupled to and physically installed on a parking spot in a parking lot; and
a mobile robot device comprising a transceiver and a camera,
wherein the sensor detects, by the sensing circuit, a vehicle entering the parking spot, and transmits, by the transmitter and to the cloud server, a first wireless signal;
wherein the cloud server, upon reception of the first wireless signal by the transceiver of the cloud server, records an entry time of the vehicle, and dispatches the mobile robot device to the parking spot;
wherein the mobile robot device communicates with the sensor while being dispatched to the parking spot;
wherein the mobile robot device captures identification information of the vehicle by the camera, and transmits, by the transceiver of the mobile robot device and to the cloud server, a second wireless signal including the identification information;
wherein the sensor further detects, by the sensing circuit, the vehicle exiting the parking spot, and transmits, by the transmitter and to the cloud server, a third wireless signal;
wherein the cloud server, upon reception of the third wireless signal by the transceiver of the cloud server, records an exit time of the vehicle; and
wherein the cloud server further calculates a parking duration between the entry time and the exit time of the vehicle, and determines, based on the identification information and the parking duration, whether the parking duration has exceeded a predetermined duration.

11. The parking control system according to claim 10 ,
wherein, before receiving the third wireless signal, the cloud server calculates a balance time based on the entry time and the predetermined duration, and sends a first notification to an operator of the vehicle when the balance time is less than a threshold.

12. The parking control system according to claim 10 ,
wherein, when the parking duration has exceeded the predetermined duration, the cloud server sends a second notification to an operator of the vehicle.

13. The parking control system according to claim 10 ,
wherein the mobile robot device further comprises: a processor; and a memory storing a map of the parking lot; and
wherein the processor navigates the map to direct the mobile robot device to the parking spot.

14. The parking control system according to claim 10 ,
wherein, when the mobile robot device is dispatched to a plurality of parking spots, the mobile robot device captures the identification information of the vehicle of each of the plurality of parking spots one after another.

15. The parking control system according to claim 10 , further comprising a docking station, wherein the mobile robot device returns to the docking station after transmitting the second wireless signal.

16. The parking control system according to claim 10 , wherein the identification information comprises a license plate number of the vehicle.

17. The parking control system according to claim 10 , wherein the sensor is an ultrasonic sensor.

18. The parking control system according to claim 10 ,
wherein the cloud server, upon reception of the second wireless signal, determines whether the vehicle is authorized to park in the parking spot based on the identification information; and
wherein the cloud server sends a third notification to an operator of the vehicle if the vehicle is not authorized.

19. A mobile robot device in communication with a cloud server and a sensor coupled to and physically installed on a parking spot in a parking lot, the mobile robot device comprising:
a transceiver; a camera; a processor; and a memory,
wherein the memory stores a map of the parking lot;
wherein the transceiver receives a dispatch signal from the cloud server, the dispatch signal indicating that the sensor has detected a vehicle entering or exiting the parking lot;
wherein the processor navigates the map to direct the mobile robot device to the parking spot;
wherein the transceiver communicates with the sensor while the mobile robot device is dispatched to the parking spot; and
wherein, upon arriving at the parking spot, the mobile robot device captures identification information of the vehicle by the camera, and transmits, by the transceiver of the mobile robot device a
