Mobile detection system and method for pavement gap detection

Abstract

The invention discloses a mobile detection system and method for pavement gap detection, and the mobile detection of a pavement gap is realized by additionally installing a positioning and control module, a millimeter wave radar and a real-time processing module on a system bearing vehicle. The millimeter wave radar is used for road gap detection, compared with traditional manual detection, the labor cost is reduced, and meanwhile the detection efficiency is improved. And compared with a traditional fixed optical detection system which needs to be provided with a plurality of optical systems, the detection cost is also reduced. The millimeter wave radar is adopted for detection, stable monitoring can be carried out on tiny gaps with the width smaller than 1 cm, and the stability and comprehensiveness of detection are improved. The mobile detection system is loaded on the system bearing vehicle, all-weather uninterrupted detection can be carried out, the influence of weather conditions is avoided, and the universality and the stability of the detection system are improved.

Description

technical field [0001] The invention relates to the technical field of pavement gap detection, in particular to a mobile detection system and method for pavement gap detection. Background technique [0002] Due to rainfall, temperature changes and other reasons, cracks are prone to occur on highways, expressways, airport runways and other pavements, which affect the safety of cars or aircraft taking off and landing. [0003] The safety hazard caused by the gaps in the pavement is particularly obvious in the airport. All the pavement in the airport flight area (including: runway, taxiway, apron, etc.) Face seam, the purpose is to prevent the deformation of temperature stress. The gaps in the pavement surface must be filled and closed with relevant materials. The filling material for filling the gaps in the pavement surface has a corresponding validity period. directly jeopardize flight safety. In order to ensure the quality of the airport pavement and ensure flight safety,...

Problems solved by technology

[0004] At present, both airports and highways in China mainly rely on manual inspections and human eyes to search for cracks that need to be repaired. This method requires staff to stare at the road surface for a long time in a fast-moving car, which is prone to omissions, and at night or at night. The human eye is less reliable in bad weather conditions

[0005] Another solution is to use optical detection, but optical detection is easily affected by light, and cannot be loaded on a high-speed car (the image is easily blurred when moving at high speed). If a large number of fixed optical detection equipment is laid along the road, the cost will be too high
