Vehicle-mounted airport pavement damage microtopography image acquisition system and control evaluation method

Abstract

The invention discloses a vehicle-mounted airport pavement damage microtopography image acquisition system and a control evaluation method. The acquisition system is installed on an acquisition vehicle, and comprises a pull-type flat vehicle, a scanning electron microscope, a sealing chamber, a surface metal spraying instrument, a main control computer and a camera, wherein the pull-type flat vehicle is connected to the tail part of the acquisition vehicle, and the lower part of the acquisition vehicle is provided with the camera; and the scanning electron microscope is installed on the pull-type flat vehicle in a lifting mode and is connected with the main control computer. The vehicle-mounted airport pavement damage microtopography image acquisition system provided by the invention has the advantages that an airport pavement is not damaged, and the defect that the pavement is required to be sampled by a traditional method is overcome; the acquisition speed is high, and is not restricted by the time of suspending of air service; and a whole flight zone can be covered, so that the data sampling is more comprehensive, and the conclusion is more reliable.

Description

technical field [0001] The invention belongs to the technical field of airport facility detection, and in particular relates to a vehicle-mounted airport pavement damage micro-topography image acquisition system and a control evaluation method. Background technique [0002] Aircraft take-off and landing safety is closely related to the damage condition of airport pavement. According to statistics, the high-incidence periods of civil aircraft accidents are mainly concentrated in the stages of take-off, initial climb, and final approach and landing. This will directly affect the safe operation of the airport and the safety of passengers, and has always attracted the attention of the airport management department. Controlling the damage of airport pavement within the allowable range is an important guarantee to prevent accidents such as aircraft overrunning the runway. Therefore, how to dynamically grasp the damage status of airport pavement and predict its development law has...

AI Technical Summary

Problems solved by technology

[0003] At present, in the practice of airport pavement management, only the friction coefficient test vehicle is used to directly test the pavement friction coefficient. Since the test results of the test vehicle are limited to a single measurement line, it is difficult to cover the entire area of ​​the runway. Therefore, the evaluation of pavement damage status It is not perfect, it is limited to the macroscopic results of the friction coefficient distribution, and fails to consider the evolution process of the generation and development of pavement material damage

However, in the runway evaluation process every five years, the evaluation of pavement damage is limited to the damage types visible to the naked eye, and the mesoscopic damage cannot be observed, so it is difficult to reflect the development law of pavement damage from the perspective of the material itself
