Description

An aircraft parking guidance and distance display information system

technical field

The invention relates to aircraft berth technology, in particular to an aircraft berth guidance and distance display information system.

Background technique

In the absence of an automatic aircraft parking guidance system, the parking of an aircraft requires the assistance of multiple ground personnel, and there is room for improvement in execution efficiency. The main task of the aircraft parking automatic guidance system is to guide the pilot to control the speed and direction of the aircraft movement from the moment the aircraft leaves the taxiway and enters the apron, and at the same time make a judgment on whether the size of the parked aircraft is suitable for parking at the current parking position, until the aircraft is completely Park at the designated parking spot. In actual application, there are relatively high requirements for the measurement accuracy of the system, real-time feedback, weather adaptability and equipment reliability.

The aircraft parking automatic guidance system can provide accurate and standardized guidance for the safe and efficient parking of aircraft on the apron, and guide the pilot to park the aircraft with the optimal procedure. The aircraft parking process is an integral part of flight operations, and the use of auxiliary equipment to improve the efficiency and safety of flight operations is also an integral part of airport modernization.

Various technical solutions have been proposed to solve this problem. Early technical solutions relied on sensors installed in multiple locations to automatically guide the aircraft to park. Some sensors are installed on the ground of the apron, which are easily damaged under the surface pressure, and are not easy to maintain and replace. Newer technical solutions tend to integrate sensing devices and install them on the surface, such as terminal buildings or bridges. New technologies mainly include radar, image and laser technology. Radar signals have poor resolution to details and can accurately detect the distance of the aircraft, but it is difficult to accurately measure the attitude of the aircraft. Image technology has poor adaptability in environments with weak light and poor visibility, and the accuracy of image recognition algorithms needs to be improved in complex background environments.

detailed description

The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

As shown in accompanying drawing 1, an aircraft berth guidance and distance display information system includes a grating navigation guidance beacon, a core computing controller, a laser range finder, a touch display screen, an LED display controller and an LED display screen, The grating navigation aid beacon is connected to the core computing controller to provide pilots with guidance in the left and right directions; the laser rangefinder is connected to the core computing controller through the laser ranging data calculator to measure the front and rear distances of the aircraft. Data, the core computing controller is connected to the display screen through the LED display controller, and is used to display the distance information on the LED display screen; the display screen includes a character display LED screen and a progress bar display LED screen, and the character display LED screen is used for Display the flight information to be parked and the distance guidance information and stop command; the progress bar display LED screen is used to provide the pilot with the intuitive progress of the berthing distance by changing the length of the lit part; the core computing controller communicates with the control via the local Ethernet The communication of the central server is used to realize the remote operation and control of the system; the touch screen is connected and communicated with the core operation controller, and is used to control the system and input information through its operation interface.

Raster navaid guidance beacon set with arrows pointing to the module. The laser rangefinder uses a two-dimensional laser radar.

After adopting the above-mentioned technical scheme:

(1) Two-dimensional laser radar is used to guide the distance in the front and rear directions of the aircraft. The aircraft distance data measured by the laser radar is transmitted to the core computing controller through the network cable, and then sent to the LED display controller through the RS232 bus after being processed by the core computing controller. Then control the LED display screen to display accordingly. The character display LED screen is used to display the flight information to be parked, the distance guidance information and the stop command, and the progress bar display LED screen provides the pilot with the parking distance information in the way of changing the length of the lit part. Intuitive progress, the change rate of its length is related to the real-time forward speed of the aircraft, so that the driver can feel the speed of the aircraft taxiing more intuitively.

(2) During the parking process of the aircraft, the pilot needs guidance in the left and right directions, and the front and rear directions. When taxiing on the centerline, the pilot will see the arrow pointing in the opposite direction on the raster navigator beacon. When the aircraft does not deviate from the centerline, the pilot will see the arrow on the guide beacon disappear, so that a low-cost and more Intuitive and reliable optical equipment replaces the measurement-calculation-display system of lidar to complete the guidance of the aircraft in the left and right directions.

(3) The touch screen is used as the man-machine interface. It connects and communicates with the core operation controller through the RS485 bus, and the operator controls the system and enters information through the operation interface.

(4) The parking positions and body sizes of different aircraft are different, and some parameters are needed to guide the distance. To complete the task of guiding the aircraft, the system must know the model of the aircraft to be parked, and then it can search the corresponding data from the database stored by the system itself. The operator can start the guidance task by inputting the model to be guided from the touch screen or sending the model to be parked by the host computer. When the aircraft is parked, the system will automatically terminate the task and save the corresponding data and upload the data to Control Center Server.

(5) The core operation controller mainly completes the operation of the laser radar ranging data and the overall control of the system, as well as the coordination of various parts, mutual communication, fault detection, etc. The core operation controller can also communicate with the control center server through the local Ethernet to Realize the remote operation and control of the system.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention Inside.
