Description

Milestone management method for road pavement management {DISTANCE STWARDSHIP METHOD FOR HIGHWAY PAVEMENT MANAGEMENT}

The present invention relates to a milestone management method for road pavement management, and more particularly, by scientifically and systematically optimizing a survey milestone and a management milestone by matching a management milestone with a milestone installed on a road and a survey milestone with specialized equipment. The present invention relates to a milestone management method for pavement management that can efficiently manage pavement of roads.

At present, there are about 15,435km of highways in Korea as a primary route. Such highways are damaged due to traffic characteristics such as traffic loads due to high-speed driving and heavy traffic during rush hour, such as a truck loaded with excessive loads. Therefore, in order to continuously provide a pleasant and safe road to road users, road pavement maintenance practitioners must identify the causes of road pavement damage and perform proper maintenance according to the cause of damage at the appropriate time to maintain good pavement condition. do.

Looking at the management process of such a highway is as follows.

Signposts are installed on the side of the highway at 200m intervals from the start of the highway. Highway managers can use this signage to determine the location of a highway, the location of a facility, or the location of a broken floor. On the other hand, the ground condition of the road is surveyed by specialized equipment for pavement survey. That is, a vehicle equipped with an image measuring device and a GPS is driving a highway and photographing road surfaces at regular intervals (approximately 10m apart) to repair the damaged road at the location based on this data.

In other words, as a result of surveying the road surface with pavement surveying equipment (investigation), if the road at a specific location is damaged, the degree of damage is determined based on the image surveyed with the paving surveying equipment, and the damaged position value (GPS Coordinates) will be repaired by finding the location of the broken road based on the management road by changing the location of the signpost installed on the shoulder of the highway.

However, the pavement management method of the road according to the prior art has the following problems.

In other words, the distance between signposts installed at 200m intervals on the side of the highway is due to errors in installing signs, broken chains generated during construction work (converting curved roads into straight roads), and linkages with neighboring branches. It is not accurate due to the error, and because of the error between the trips in the process of changing the survey trip using the professional measuring equipment to the management trip, it is difficult to find the repair position of the road based on the survey trip measured by the professional measuring equipment. There was this.

This will be described as follows.

In the accompanying drawings, when road repair is required in a 1.3 to 2.7 km section based on a survey survey conducted by professional measuring equipment as shown in FIG. -Since it is 2.6km, an error of about 100m occurs between survey and management routes, making it difficult to maintain accurate roads.

As such, the management milestone has an error due to various factors, so there was a lot of difficulty in managing the pavement using the road.

The technical problem of the present invention is that the road maintenance personnel use the survey and analysis signs measured by the professional measuring equipment to find the exact repair position on the actual highway site in order to utilize the survey and analysis result by the professional measuring equipment. It provides a means to harmonize management initiatives.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted to clarify the gist of the present invention.

2 is a flowchart illustrating a milestone management method for pavement management according to a preferred embodiment of the present invention, Figure 3 is a view for explaining a preferred embodiment of the present invention.

Hereinafter, 'management milestones' and 'investigation milestones' refer to data for pavement management of roads, and 'management milestones' refer to structures such as signposts, bridges, and tunnels indicating distances installed on shoulders such as highways. It is numerical data such as location, and 'exploration trip' means data such as actual road condition, distance, location, image, etc., measured by GPS or imaging equipment.

Referring to the milestone management method for pavement management on the basis of Figures 2 and 3 as follows.

a) step

First, using GPS (GPS-satellite navigation) equipment, the coordinates of each signpost 100, bridges, and tunnels installed on the shoulders of roads, in particular, highways, are measured for the points where the respective milestones and structures are installed or located. Obtain administrative coordinates respectively.

For example, the coordinates are extracted from the points where the two signposts 100 are installed, the coordinates of the start point and the end point of the bridge are extracted, and the coordinates of the start point and the end point of the tunnel are respectively extracted.

Each signpost 100 displays the distance from the point where the highway starts, and is installed at intervals of 200 m. However, since the distance between each signpost 100 is not constant and is not accurate for various reasons, it is to obtain the coordinates for management milestones by measuring the respective positions.

At this time, the coordinates of the tunnel and the bridge are surveyed because the names, positions, and the like of specific structures are determined and are easy to find. In the case of the tunnel, it is difficult to measure the coordinates therein, so it is preferable to measure the coordinates of the starting point and the ending point.

b) step

Subsequently, the road surface of the highway is photographed at a predetermined distance unit, approximately 10m apart using specialized equipment for inspecting the pavement state of the highway, and the distance and coordinates are measured to obtain distances for survey ease and distance for survey ease.

These specialized equipment are installed in the vehicle, and while the vehicle is traveling at a constant speed, the distance is measured at intervals of 10 meters, and the road surface is photographed to obtain data on the road surface, and the position, such as the distance between the survey lift and the coordinates for the survey lift. Will extract the data.

c) step

Subsequently, the management ease coordinates extracted in step a) and the survey ease coordinates are compared relative to each other to detect the management ease coordinates closest to each other.

That is, as shown in FIG. 3, when the coordinates for the administration and the coordinates for each survey are extracted, the two data are compared and detected to detect the coordinates for the administration and the closest coordinates.

For example, when the survey coordinates at any point are x'3, y'3.1, the survey coordinates are closest to x2, y3 among the coordinates. At this time, the coordinates for management milestones of x2 and y3 are the coordinates of the signpost 100 of '100.4'.

In this way, the relative comparison between the coordinates for survey and management administration is compared to detect the coordinates for administration and administration closest to the coordinates for investigation.

At this time, it may be possible to detect the coordinates for the management milestone which is close to the selected one and the coordinates for the survey milestone, or to detect the management milestones closest to the respective coordinates for the irradiation milestone. Thus, one management assignment coordinate may have a plurality of adjacent survey departure coordinates.

In this way, the detection of the coordinates for the management milestones close to the coordinates for the survey milestones is for converting the survey milestones to the management milestones, and the manager accurately finds the position according to the data of the survey milestones 100 on the site.

d) step

Subsequently, the surveying distance obtained from the above-described surveying distance is detected from the surveying distance measured in step c) described above. That is, to detect the coordinates for the survey departure coincident with the coordinates for the management guidance detected in step c). This means that when the specialized equipment measures the distance and image and coordinates of the highway, each distance has a coordinate, and thus detects a coordinate corresponding to the distance for the survey survey. However, the present invention is not limited thereto, but may also detect and use a survey distance corresponding to administrative coordinates.

In this way, detecting the distance between the survey milestones coinciding with the management milestones is to determine how far the position of the survey milestone coordinates (coordinates close to the coordinates of the management milestones) to be converted to the management milestone is maintained relative to the management milestone coordinates. It is to.

e) step

In the above-described process, when the management easy coordinates closest to the specific coordinates are detected, and a distance (or coordinates) for which the irradiation easy coincides with the coordinates is detected, the distance is changed to the management ease. In other words, the distance between the survey walks, which coincides with the management walk-up coordinates closest to the survey walk-up coordinates, is transformed into a management trip that can be directly utilized by site managers.

As such, there may be a variety of methods for converting a survey milestone into a management milestone, but there may be two ways in this embodiment.

First, based on the coordinates of the management ease detected in step d) described above, the distance between the irradiation ease in 10m units is relatively accumulated, and the coordinates of the irradiation ease are changed into management ease and converted into management care.

In other words, the distance from the survey sign 100 to the survey milestone coordinates of the point to be converted is detected based on the distance between the survey milestones corresponding to the management milestones of the tunnel or the bridge. Subsequently, after detecting the distance of the management miles plus the distance of the irradiation strokes by adding the distance of the irradiation miles detected by the above-described process to the distance (the distance described on the milestone signs) of the milestone sign 100 corresponding to the coordinates for the management milestones, , To convert the coordinates for the irradiation release of the point to be converted to the distance of the signpost (100).

For example, when the distance indicated on the milestone sign 100 corresponding to the administrative ease coordinates is 100.4, and the survey easel distance corresponding to the management ease coordinates is 100.4, a point to be accumulated and converted at a distance of 10 m from the distance of the survey easel Detects the distance of the coordinates for surveying. In this process, it is possible to find out how far the coordinates for the survey pilot are from the survey pilot distance. If the distance is 30m, the distance of 100.43 is extracted by adding 30m to the distance of 100.4, which is the coordinate of the administrative ease, and converts the coordinates (distance) for the survey interest to 100.43. In this way, since the survey milestone data (distance or coordinate) is converted into a management milestone based on the milestone sign 100, the manager can easily and accurately find the survey milestone data on the basis of the milestone sign 100 of the management milestone in the field. It can be.

On the other hand, the switching method according to another embodiment is as follows.

 e-1) step

The section between the management milestone coordinates detected in the above-described steps and other management milestones adjacent to this management milestone is equally distributed.

step e-2)

Subsequently, the intervals between the surveying coordinates corresponding to each of the management assignment coordinates in step e-1) are equally distributed.

e-3) step

Subsequently, the coordinates for irradiation survey assignments equally distributed in the above step e-2) are converted to management administration coordinates.

In other words, the distance between each signpost 100 is equally distributed, the distance between each point having the coordinates for survey milestones corresponding to the milestone signs 100 is equally distributed, and the point having the coordinates for survey milestones requiring repair is required. After detecting, the detected point is converted into an equally distributed point of the coordinates for management milestones corresponding to the detected points, thereby converting the survey milestones into management milestones.

In other words, if the distance between the points having the survey milestones corresponding to the milestone signs 100 is equally distributed, the distance from the distance (or coordinates) for the survey milestones corresponding to the management milestones to the point requiring repair is determined. By converting this distance into coordinates for management administration, the distance (position) according to management administration of the point requiring repair can be identified.

On the other hand, Figure 4 of the accompanying drawings shows another embodiment of the present invention.

Another embodiment is to compare the administrative ease coordinates with the survey ease coordinates to detect the management ease coordinates that match the survey ease coordinates, and then convert the investigation ease coordinates that match the detected care ease coordinates to the management ease. Is the same as the above-described embodiment.

In other words, when the coordinates for the management guideline are 100.4, if the coordinates for the survey guideline corresponding to the management guideline coordinates are converted to the management guideline, the coordinates for the survey guideline correspond to the milestone signs of 100.4.

Meanwhile, another embodiment is as follows.

That is, after detecting the coordinates of the management and the adjacent coordinates of the management and detect the distance between the two coordinates and the distance between the two coordinates, and the distance between the two coordinates detected and the distance between the two points. The number of pictures taken. The same procedure as in the above-described embodiments is performed except that the interval between the two management milestones is equally divided by the number of detected pictures to convert to a management milestone.

This will be described as follows.

Specialized equipment for measuring the pavement state of the road while taking a predetermined distance unit, for example, 10m intervals while driving the road while shooting the road surface at the same time to detect the coordinate value of the position, and to measure the distance.

Therefore, after detecting the number of photographed photographs in the section between two surveying coordinates or the distance between survey survey distances, if the sections between the two management milestones are equally distributed by the number of photographs, the two coordinates The interval between the 10m intervals are regularly divided so that the worker can easily find the working position based on this.

For example, suppose that professional equipment photographs the road surface at 10m intervals, and if the number of photographs detected between the two coordinates is 16, the interval between the two coordinates is equally distributed to 16 and is divided into the control interval. By switching, the operator can easily find the maintenance position.

In other words, since two coordinates and two survey coordinates coincide with each other, it can be seen that the interval between the two coordinates (the interval between the two signposts) is 160m instead of 200m for various reasons. That is, since the road surface was taken at regular intervals of 10m, it can be seen that it is 160m. At this time, the number of photographs is determined first to include a photograph corresponding to two coordinates for survey surveys, or to apply only the photographs within the section, and the numerical value (number of photographs) is obtained.

As described above, after obtaining coordinate values for management milestones of the signpost 100 and the like, measuring roads with specialized equipment and converting the survey milestones measured by specialized equipment into management milestones, the repair positions measured and detected by specialized equipment. It can be found accurately and easily through management administration in actual field.

While specific embodiments of the invention have been described and illustrated above, it is to be understood that the invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the invention. It is self-evident to those who have. Therefore, such modifications or variations are not to be understood individually from the technical spirit or point of view of the present invention, the modified embodiments will belong to the claims of the present invention.
