Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a road surface disease automatic positioning and filing system and filing method. Background Art

[0002] Cement and asphalt pavements of highways and bridge decks will gradually develop various deformations, damages, or other problems after being opened to traffic for a period of time. This article calls them pavement diseases or diseases. The geometric shapes of common diseases can be divided into point damage, linear cracks, and irregular surface damage. Cracks can be as short as 1 meter or as long as tens of meters or longer; surface damage is mostly irregular in shape and can cover an area of ​​tens of square meters or larger. It can be potholes, subsidence, surface damage, or mixed damage. Generally speaking, small diseases can gradually evolve into large diseases if they are not maintained. For roads or bridges with heavy traffic, the evolution process is faster, causing vehicles to be damaged to varying degrees, further destroying the road surface, and even causing various accidents.

[0003] Finding road and bridge deck defects and tracking their evolution, i.e., their history, is a laborious, time-consuming, and error-prone task. Several kilometers of road surface can sometimes have thousands of defects. Accurately locating each defect, recording the history, planning the repair of the defect, on-site construction, and subsequent follow-up require a large number of management and maintenance personnel. In fact, due to a shortage of manpower, this task is often difficult to complete successfully.

[0004] Currently, the work of tracking the history of road disease and building files is mostly done manually or semi-automatically. The former relies entirely on manual recording and file building. This method is inefficient in every link, and more importantly, it cannot accurately describe the location of the disease. Once the disease is found, unless the characteristics are obvious or in a landmark position, it is difficult to identify and track it later, and the medical history cannot be continued.

[0005] The semi-automatic method can use a locator to manually record the location, and then enter the system to create a file after returning to the office. This method is obviously better than the manual method, and can locate the disease, create files and track it, but the efficiency is still low. This is because the semi-automatic method cannot automatically classify the disease type, calculate the disease area, etc. More importantly, relying on manual updates and file creation is not only inefficient, but also more prone to errors.

[0006] Therefore, it is crucial for technical personnel in this field to develop a wireless pavement disease fully automatic positioning and filing system and method, automatically locate pavement and bridge deck diseases, intelligently identify disease characteristics, automatically file the diseases and analyze data, greatly improve the efficiency of pavement and bridge maintenance work, and save considerable labor costs.
