Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation airports, and in particular to an intelligent identification and guidance system for intelligent road signs. Background Art

[0002] The passenger boarding process at each civil airport is that passengers find the check-in counter of the flight they are taking, use valid documents to print paper boarding passes at the check-in counter or self-service check-in machine, and if they have applied for electronic boarding passes online in advance, they can also go through security directly with the electronic boarding passes. After security check, they enter the passenger waiting area with the boarding pass and resident ID card, and learn the location of the boarding gate and boarding time according to the information on the boarding pass through the flight information display screen, road signs or by consulting airport staff. The process of finding the boarding gate requires passengers to constantly observe various road signs, which makes it easy to go wrong. In addition, due to flight delays and boarding gate changes, the boarding gate on the boarding pass will not match the actual boarding gate. Passengers need to spend more time to find a new boarding gate to obtain change information through broadcasting and other channels, which reduces the boarding efficiency of passengers. Therefore, the research on the intelligent recognition and guidance system for intelligent road signs is of practical significance for passengers to find the boarding gate in the waiting area.

[0003] Chinese patent publication number: CN107665358A, discloses an interactive boarding guidance method and guidance system thereof, aiming to provide an interactive boarding guidance method and guidance system that is easy to use. The interactive boarding guidance system includes a barcode scanner, an ID card reader, an industrial computer, and a touch screen; the industrial computer is respectively connected to the barcode scanner, the ID card reader, and the touch screen for communication; the barcode scanner is used to read the barcode or QR code information on the boarding pass, and send the read string information to the industrial computer; the ID card reader is used to read the information on the second-generation ID card, and send the read string information to the industrial computer; the touch screen is used to display the terminal geographic information and guidance information sent by the industrial computer, and receive user operations.

[0004] It can be seen that the above scheme uses the QR code on the paper or electronic boarding pass to provide boarding guidance to passengers in the form of dynamic images on the touch screen through human-computer interaction. However, the above scheme cannot achieve real-time monitoring of the integrity of the boarding information obtained based on the QR code features, nor can it achieve real-time monitoring of the authenticity of the corresponding boarding area retrieved from the database based on the boarding information, so it cannot guarantee the accuracy of path planning based on the QR code features, nor can it guarantee the working efficiency of the intelligent recognition guidance system for intelligent road signs.

The intelligent identification and guidance system for intelligent road signs according to claim 4, characterized in that: The central control module is also used to determine the reason why the integrity of the boarding information obtained after decoding processing does not meet the standards based on the difference in the proportion of abnormal information; the central control module is also used to increase the noise reduction factor of the image information based on the secondary abnormal information difference based on the determined reason, or issue a notification that the scan does not meet the standards.

7. The intelligent identification and guidance system for intelligent road signs according to claim 2, characterized in that: The central control module is also used to determine whether the authenticity of the corresponding boarding area retrieved from the database meets the standards based on whether the path planning module can identify the boarding information; the central control module is also used to issue an authenticity non-compliance notification when it is determined that the authenticity of the corresponding boarding area retrieved from the database does not meet the standards, or to determine whether the boarding area matches the boarding information when it is determined that the authenticity of the corresponding boarding area retrieved from the database meets the standards.

8. The intelligent identification and guidance system for intelligent road signs according to claim 7, characterized in that: The central control module is also used to determine whether the boarding area matches the boarding information, perform path planning according to the determination result, or determine the reason why the boarding area does not match the boarding information based on the time node difference; Among them, the time node difference is the difference between the identification time node and the current time node, the identification time node is the time node for identifying the boarding information, and the current time node is the boarding time node of the boarding information.

9. The intelligent identification and guidance system for intelligent road signs according to claim 8, characterized in that: The central control module is also used to determine the reason why the boarding area does not match the boarding information based on the time node difference, and generate a corresponding processing method based on the determined reason, including: performing path planning when it is determined that the time node of the boarding information is greater than the time when check-in stops, increasing the update frequency of the map construction module for the map information based on the time node difference when it is determined that the time node of the boarding information is close to the time when check-in stops, or issuing a missed flight notification when it is determined that the time node of the boarding information is less than the time when check-in stops.

10. The intelligent identification and guidance system for intelligent road signs according to claim 9, characterized in that: The central control module is also used to increase the update frequency of the map construction module for the map information based on the time node ratio, and the increase in the update frequency of the map information is inversely proportional to the time node ratio; wherein the time node ratio is the ratio of the time node difference to the pre-stored preset time node difference.
