Description

Technical Field

[0001] The present invention relates to the fields of robots and airport services, including functions such as airport guidance, direction, and luggage transportation. Background Art

[0002] Under the growing passenger flow and the demand for efficient and convenient services, relying on artificial intelligence, the Internet of Things, big data analysis, and high-precision sensor technologies, robots can complete tasks such as information query, security inspection assistance, checked luggage handling, and personalized passenger guidance, effectively alleviating the manpower pressure at airports, improving service efficiency and quality, and bringing a more intelligent and user-friendly travel experience to passengers. Summary of the Invention

[0003] The purpose of the present invention is to design an intelligent service robot that can answer questions, guide the way, and assist passengers in need of checked luggage at the airport.

[0004] Users can voice their needs to the robot to achieve common information questions and answers, navigation to common locations, and security inspection and check-in of luggage.

[0005] This robot can identify when a person faces the machine through a camera and then start the subsequent conversation.

[0006] This robot has a Q&A library related to the airport, which contains various common check-in questions and aims to help users understand various relevant information.

[0007] This robot stores an internal map of the airport and can provide navigation services for users to different locations.

[0008] Users can use this robot for security inspection and check-in of luggage and can assist in handling checked luggage.

[0009] The intelligent airport service robot uses a customized touch display as the display screen.

[0010] The intelligent airport service robot uses a rechargeable lithium iron phosphate battery with a nominal voltage of 48.0V and a nominal capacity of 40000mAh to provide the required power support for the robot.

[0011] The intelligent airport service robot uses a circular microphone array to achieve user voice input.

[0012] The intelligent airport service robot uses a 20mm internal magnetic horn speaker

[0013] The intelligent airport service robot uses a BB700 UHF printer to print luggage tags.

[0014] For checked luggage at the airport: 20-inch, 22-inch, 24-inch, 28-inch, and 30-inch luggage. Different-sized robots can be used according to different luggage sizes. The robots corresponding to the luggage sizes are 150 cm type, 160 cm type, 170 cm type, 180 cm type, and 190 cm type. Given that the common luggage sizes are 22 inches and 24 inches, the 160-type and 170-type are used more frequently. Brief Description of the Drawings

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] As Figure 1 shown, the intelligent airport service robot includes a head housing (1-1) and a body housing (1-2). Two sound pickup devices (1-5) on the head are used to obtain sound input, a camera (1-4) is used to obtain surrounding environment information, a screen (1-8) is used to display information, a speaker (1-6) is used to output sound, a printing port (1-7) is used to output the printing result of the luggage tag, and the chassis (1-3) is at the bottom;

[0023] As Figure 2 shown is the rear view of the intelligent airport service robot, and a charging port (2-1) is used to charge the robot;

[0024] As Figure 3It is a bottom view of an intelligent airport service robot. There are DC motor 1 (3-1), DC motor 2 (3-2), DC motor 3 (3-3) and DC motor 4 (3-4), and their corresponding wheels 1 (3-5), wheels 2 (3-6), wheels 3 (3-7) and wheels 4 (3-8). The four motors and the wheels control the movement of the robot. When the four wheels move forward simultaneously, the robot moves forward; when the four wheels move backward simultaneously, the robot moves backward; when wheels 1 (3-5) and wheels 2 (3-6) move forward and wheels 3 (3-7) and wheels 4 (3-8) move backward, the robot turns left; when wheels 1 (3-5) and wheels 2 (3-6) move backward and wheels 3 (3-7) and wheels 4 (3-8) move forward, the robot turns right.

[0025] Figure 5 The figure shows a schematic diagram of the closed state of the inner cavity of the intelligent airport service robot. The retracted extended conveyor belt (5-1), conveyor belt (5-2), and the flat panel detectors (5-4) on both sides of the inner wall and the top form the inner cavity. Below the conveyor belt is the wire control box (5-3) with an in-built laser punctuation device. Figure 6 It is a schematic diagram of the opened inner cavity of the intelligent airport service robot. The extended conveyor belt (5-1) is opened and laid flat to facilitate the placement of luggage.

[0026] After the inner cavity is opened, the luggage is placed on the extended conveyor belt (5-1). Then, the extended conveyor belt (5-1) and conveyor belt (5-2) are started to move the luggage into the inner cavity. After that, the wire control box (5-3) and flat panel detectors (5-4) are started to conduct security checks on the luggage.
