[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] Please also see Figures 1 to 3A preferred embodiment of the present invention provides an RFID intelligent parking monitoring method, comprising the steps of:

[0036] S1. Determine whether a preset condition is met, wake up when the condition is met, read the tag information of the RFID tag, and determine whether the RFID tag information is valid;

[0037] S2: When the time for which a valid RFID tag is continuously identified exceeds a set value, the RFID tag information is valid;

[0038] S3, judging the angle of camera adjustment according to the number of antennas of the RFID tag identified and the RSSI strength, and taking photos or videos;

[0039] S4. Upload the read tag information and the collected corresponding image data to the server, and the server matches according to the tag information and records it in the charging information system.

[0040] Specifically, in step S1, RFID tags are identified in real time to detect whether there are vehicles nearby. RFID tags can be identified through a preset period, which can be set by the user or automatically set by the device according to time, location, environment, etc. The RFID radio frequency or antenna can also be awakened for detection according to trigger conditions. Since there is a lot of RFID tag information, if all of it is processed, the power consumption will be high. Therefore, it is necessary to judge whether the tag information is valid, which can reduce power consumption. The tag information is a segment number that can uniquely identify the vehicle. When it is issued by the vehicle management center, there will be corresponding judgment criteria, such as encoding method, encryption method, segment range, etc.

[0041] Specifically, in step S2, when the time length of continuous identification of a valid RFID tag exceeds a set value, the RFID tag information is valid. When the time length of continuous identification of an RFID tag exceeds a set value, it indicates that the vehicle has been parked and monitoring is necessary.

[0042] Specifically, in step S3, the camera adjustment angle is determined according to the number of antennas of the RFID tag identified and the RSSI strength, and photos or videos are taken. Figure 5It can be seen that the RSSI intensity is strongest in the direction perpendicular to the transmitting surface of the antenna unit of the RFID. As the deviation in the direction perpendicular to the transmitting surface increases, the RSSI intensity weakens. When it deviates to the top surface, the RSSI intensity weakens, and when it deviates to the bottom surface, the RSSI intensity also weakens. In the process of deviating to the bottom surface, the opposite antenna can gradually detect the RFID tag and the RSSI intensity detected by the opposite antenna will gradually increase. If the number of antennas that identify the RFID tag is one, the angle of camera adjustment is determined according to the RSSI intensity of the RFID tag identified by the antenna, and photos or videos are taken. Preferably, when the RSSI intensity is detected to exceed a certain threshold, the camera is adjusted to face the same direction as the transmitting surface of the RFID antenna, otherwise the camera is offset toward the top surface according to the RSSI intensity. If the number of antennas that identify the RFID tag is multiple, the offset angle is determined according to the ratio of the RSSI intensity of the multiple antennas, and the camera is adjusted to the side with stronger RSSI. When the RSSI intensity of two antennas is equal, the camera is adjusted to directly below.

[0043] Specifically, in step S4, the tag information and the captured image or video data are associated, and the information is sent to the server through the device's own network or through an external transfer device. The associated and sent information may further include the read tag time, tag location information, device identification, and other information.

[0044] After receiving the above information, the server determines whether it is valid and feeds back the processing results to the device for remote monitoring and management. When necessary, the information can be fed back to the car owner through communication.

[0045] The server's database stores information related to tag information, vehicle description information, and owner information, and can remotely monitor and manage the vehicle. After receiving the tag information, the server searches the database to see if there is a tag information item that matches the tag. If so, remote monitoring and management are performed, and a successful processing message is fed back to the device. Otherwise, a failed processing message is fed back to the device.

[0046] Furthermore, the server receives the tag information or image data sent by the device, as well as at least one information such as the tag reading time, the tag location information, and the device identification. The server's database pre-stores the tag information, the vehicle description information, and the associated information of the owner, which is preferably stored when the RFID tag is sent. After receiving the tag information, the server searches the database to see if there is a tag information item matching the tag. If so, remote monitoring and management are performed, and processing success information is fed back to the device, otherwise processing failure information is fed back to the device.

[0047] Furthermore, the server's database pre-stores vehicle description information, such as at least one information such as license plate number, vehicle color, and vehicle model. The server matches the received tag information and image, video, and other information with the vehicle description information of the corresponding tag in the database. If there is a mismatch, it can be considered that the RFID tag is not affixed to the corresponding vehicle, and the vehicle's location, image, video, tag information, etc. will be sent to the relevant department. The owner's contact information can also be searched in the database, and the above information will be sent to the corresponding owner's email, computer or mobile phone.

[0048] Furthermore, the server determines whether the device's identification matches the illegal parking section, and if so, issues an alarm. The server determines whether the vehicle is in the illegal parking section based on the device's identification. If so, the vehicle's location, pictures, videos, and tag information are sent to the relevant departments, and the owner's contact information can be found in the database. The above information is sent to the corresponding owner's email, computer, or mobile phone.

[0049] Furthermore, the server determines the time when the tag information is received for the first time and the time when the tag information is received for the last time, and calculates the parking time for billing management.

[0050] Furthermore, the method further includes step S5, receiving the processing result returned by the server, and monitoring the tag according to the processing result. The device receives the processing result returned by the server, and when the processing result is successful, it continues to monitor the tag. When the processing result is a processing failure, when the tag is read again, it can be determined that the tag is invalid, and there is no need to take a photo of it. Therefore, there is no need to adjust the angle of the camera, and there is no need to take photos and upload them, which can save the power of the device.

[0051] Please also see Figure 4 and Figure 5 Another preferred real-time method of the present invention provides an RFID intelligent parking monitoring device, including a structural module, a reading module, a camera module, a judgment module, an adjustment module, a sending module and a receiving module.
