Embodiment Construction

[0039] The present invention will be described in detail below in combination with specific embodiments.

[0040] The system frame diagram of the test system of the present invention is as figure 1 As shown, the maximum range of the laser ranging sensor 1 can reach 100m (natural reflection surface), and the ranging accuracy is less than 5cm. In order to meet the requirements of measuring high-speed moving objects, its measuring frequency can reach 4KHZ. The main function of the laser ranging sensor 1 is to measure the distance between the tire of the aircraft passing the sensor position and the sensor, and transmit the tested data to the time synchronization and data processing unit 3 . The high-speed camera 2 adopts a 100HZ high-speed industrial camera, which is used to record the complete image of the aircraft passing by, and transmits the data to the time synchronization and data processing unit 3 . The time synchronization and data processing unit 3 is used to receive the...

Abstract

The invention discloses an airfield runway traffic volume distribution testing system and method. Laser ranging sensors, high-speed cameras, time synchronizing and data processing units, a power supply unit, a data storing unit and a computer are arranged on a runway. The laser ranging sensors are used for measuring the distances between near side tires and laser testing units when an aircraft glides. The high-speed cameras are used for recording the complete movement process of the aircraft in the corresponding area. The time synchronizing and data processing units are used for screening testdata of the laser ranging sensors and the high-speed cameras and marking all the screened effective data with unified time parameters. The data storing unit is used for storing the data processed bythe time synchronizing and data processing units. The computer is used for conducting later analyzing and processing on the data stored by the data storing unit. The system has the advantages that data testing and collecting are fully automatically conducted, and the testing precision and continuity are improved.

Description

technical field [0001] The invention belongs to the technical field of airport runway data detection, and relates to an airport runway traffic volume distribution test system and a test method. Background technique [0002] Accurately grasping the traffic volume distribution of airport runways is an important prerequisite for rational design of airport runways. In order to achieve this purpose, there must be a suitable method to test the distribution of traffic volume on the airport runway. The traffic distribution test on the airport runway is multi-faceted, including the distribution of aircraft takeoff and landing points, the lateral distribution of wheel tracks in different sections, and the distance of aircraft running. At present, there is no method that can test all these items comprehensively and accurately, and a test plan needs to be designed individually for a certain item. For the testing of a single project, the current methods also have problems of varying de...
