Detecting system for road cracks

Abstract

The invention discloses a detecting system for road cracks. The system comprises an information collecting system, a data storing and displaying system, a power management system, a data processing system and a GPS positioning system. Road damage information is collected by video records of the information collecting system; damages are positioned by combination of the GPS data and road milepost numbers obtained by the GPS positioning system; and damage conditions are identified by applications of a digital picture processing technique of the data storing and displaying system; so that objective and stable results are obtained, and the damages can be positioned and measured quickly and accurately. Requirements for road crack detecting are met, wherein the requirements comprise that: real-time monitoring for relevant information, storing and playback of data, real-time correlating of the GPS information with the road milepost numbers, and information measuring of crack conditions. The vehicle-mounted detecting system is designed, and is used to meet application requirements for road crack detecting.

Description

technical field [0001] The invention relates to the technology in the field of automatic detection, in particular to a pavement crack detection system. Background technique [0002] Due to the impact of traffic load and natural factors on expressways, various damages will gradually occur on the pavement. Among them, pavement cracks are an important feature of pavement diseases, and their detection methods have always been concerned. [0003] The traditional identification of asphalt pavement cracks in my country mainly relies on manual detection, which has four obvious defects: it relies on the experience of the staff, and there is no uniform standard for the measurement results; the safety of personnel during work is poor, and the measurement environment is harsh; the collection and measurement take a long time and the work efficiency is low. Low; raw data incomplete and measurement data difficult to validate. As early as the mid-to-late 1980s, foreign countries started to...

Problems solved by technology

[0003] The traditional identification of asphalt pavement cracks in my country mainly relies on manual detection, which has four obvious defects: it relies on the experience of the staff, and there is no uniform standard for the measurement results; the safety of personnel during work is poor, and the measurement environment is harsh; the collection and measurement take a long time and the work efficiency is low. Low; source data incomplete, measurement data difficult to validate

As early as the mid-to-late 1980s, foreign countries started to carry out relevant researches, but the products were subject to many restrictions in the reference: imported equipment was expensive and difficult to promote; the uniformity with domestic technical standards was poor; equipment repair, maintenance, calibration and other work had technology dependency
