Description
Technical Field
The invention relates to the field of pavement detection, in particular to a highway technical condition detection system.
Background
The detection of the cracks on the road surface is one of important research contents of the traffic engineering subject, the research significance of the detection is to seek a road smoothness detection scheme for ensuring optimal road surface bearing capacity, optimal vehicle driving smoothness, minimum road traffic accidents and minimum fuel consumption, provide sufficient advanced technical guarantee and theoretical support for road pre-maintenance, and achieve the purpose of harmony and unification of roads, people and vehicles.
The rapid increase of the total road mileage plays a very important role in promoting the economic development of various regions, and meanwhile, the long-term use of the road brings unprecedented challenges to the maintenance of the road. On one hand, the road surface is increasingly seriously damaged by the problems of rapid increase of traffic flow, overload of large trucks and the like; on the other hand, the construction of large engineering machinery in the pavement maintenance process can cause long-time congestion of the highway, and the traffic capacity of the road is seriously influenced.
Therefore, the method has the advantages that the pavement cracks are regularly detected and quantitatively evaluated, so that the pavement cracks are in a reasonable range, the pavement is actively maintained at an early stage, and the method has important significance for prolonging the service life of the highway, improving the traffic capacity of the road, ensuring the driving safety of automobiles and reducing the maintenance cost of the highway.
The detection of the road cracks mainly stays in a manual measurement mode, namely, workers walk along the road to observe the condition of the road, and manually input the position and the disease type of the road to form a record after finding that the road has abnormal conditions (diseases).
In view of the above situation, a document with chinese patent publication No. CN103255700B discloses a vehicle-mounted mobile road surface crack machine vision detection system, which aims to overcome the problem that the road surface crack image acquisition and the road surface condition evaluation cannot be realized.

The design provides a vehicle-mounted mobile non-contact automatic detection system which can automatically acquire road surface images and evaluate the road surface damage condition through machine vision.
In the system, because machine vision (camera) is used for acquiring road surface images and evaluating the road surface damage condition, when sundries or water exist on the ground, the estimation of the road surface damage is very inaccurate. And because install in the dead ahead of car, when gathering road surface image, because receive the influence of collection speed, influence driving speed has certain restriction, in some road surfaces, has certain driving safety hidden danger. Therefore, in the occasion that the road surface needs to be accurately evaluated, the mode of manual observation is accepted in the industry, but the mode of manual observation of the road surface has the problems of low efficiency and inaccurate record.
Disclosure of Invention
The invention provides a road technical condition detection system aiming at the technical problems of low efficiency and inaccurate record of the existing road pavement evaluation mode.
The basic scheme provided by the invention is as follows: road technical condition detection system includes:
the walking module is used for enabling a worker to drive without depending on two hands and stably run on a road at a low speed;
the positioning module is used for acquiring the position parameters of the walking module on the road in real time;
the recording module is used for recording the type of the diseases and the shapes of the diseases for the workers after the workers observe that the road has the diseases, and calling the current position parameters in the positioning module to record the disease occurrence places after the workers record the type of the diseases and the shapes of the diseases;
the report generation module is in signal connection with the recording module, is used for receiving the types of the diseases and the shapes of the diseases recorded by the recording module and the information of the disease occurrence places to generate disease results, and is also used for generating disease reports according to the position parameters by using a plurality of disease results.
The working principle and the advantages of the invention are as follows: the electric bicycle runs stably at a low speed, wherein the low speed refers to the speed of 20 kilometers per hour or less (the national standard is that the electric bicycle runs at a speed of more than 40 kilograms and more than 20 kilometers per hour and is classified as a motor vehicle category); the stability means that the worker can stop driving by operating the walking module at any time. When the walking module is used, the walking module bears workers (or users) to run on a road, and in the running process of the walking module, the workers can observe the disease condition on the road. The positioning module can acquire the position parameters of the walking touch on the road in real time in the running process of the walking module.
The disease condition on the road can be seen in the industry standard of the people's republic of China, JTG H20-2007, the assessment Standard of the technical status of the Highway, published by 2007-11-28, implemented by 2008-02-01, published by the department of transportation of the people's republic of China, and the publishing company of the people's transportation. In this standard, damage is classified into 21 items of 11 categories for asphalt pavement, including cracks, block cracks, pits, and the like. In this standard, "detection of road surface damage condition, preferably an automated rapid detection method, and manual detection when no condition is available" is described, and when detecting road surface damage by rapid detection equipment, longitudinal continuous detection is required, and the transverse detection width portion is less than 70% of the lane width. The detection equipment can distinguish the pavement cracks of more than 1mm, the detection result is automatically identified by adopting a computer, and the identification accuracy rate is more than 90 percent. "when manually investigated, the investigation range should include all lanes, and the damage types specified in tables 6.2.1-2, 6.2.1-3 and 6.2.1-4 are investigated on the spot. "the road surface damage detection data should be stored for a long period of time in units of 100m (manual detection) or 10m (rapid detection)".
The existing automatic rapid detection method is limited by hardware performance and safety performance in the detection process (unmanned evaluation cannot be realized, and the cost reduction is limited), and parameters of a detection result often cannot meet the requirements of the standard. In the scheme, the working personnel drive on the road through the driving and walking module, so that the working personnel do not need to travel on the road in a walking mode, and the walking burden of the working personnel is reduced. In the walking process of the positioning module, the positioning module can acquire the position parameters of the walking module on the road in real time.

And the report generation module generates a disease result according to the type and shape of the disease recorded by the recording module and the occurrence place (position parameter) of the disease, and generates and stores a plurality of disease results on one road into a disease report. The report is directly generated by a report generation module, and the generated result meets the national standard (JTG H20-2007), can be directly submitted and is convenient for workers to use.
According to the road technical condition detection system, the positioning module and the recording module are arranged on the walking module, and the walking module can enable a worker to drive by both hands, so that both hands of the worker are liberated in the driving process of the walking module, the worker can stop in the driving process or directly stop, and the condition of observing road diseases is recorded on the recording module. The working personnel drive on the road through the driving and walking module without verifying the road walking, thereby improving the evaluation efficiency of the road surface. And because the positioning module can position the position parameters of the walking module in real time, when the position parameters are recorded by workers, the position parameter information of the disease is recorded, and the type and the shape of the disease are observed by the workers, so that the accuracy of recording is ensured.
