Problems solved by technology

The compaction detection can only detect the data of the road section passed by the road roller, and there are often places that are ignored, and when the network is not good or the hardware data is lost, it will have a great impact on the collection accuracy
Due to the fact that in the actual construction process, the walking path of the road roller is often random and repetitive, the direct display of the obtained GPS data alone and the direct observation of man-made errors are very large
In addition, there is also a way to directly calculate the repetition of points according to the arrangement of longitude or latitude as the number of constructions. Since the roads are not necessarily along the direction of longitude or latitude, or when the amount of data is large, the change is difficult to see, so It is also easy to make mistakes

Embodiment Construction

[0038] Such as figure 2 As shown, a method for counting the number of roller operations, the method includes the following sequence of steps:

[0039] (1) Obtain GPS data and judge whether it is valid. If the judgment result is yes, store the valid data according to the collection time and go to the next step; otherwise, delete the invalid data;

[0040] (2) Convert the longitude and latitude coordinate data in the stored GPS data from the WGS-84 spherical coordinate system to the plane Cartesian coordinate system xOy;

[0041] (3) Based on the data storage time sequence, select the initial point M(x m ,y m ), and calculate the difference between this batch of data and the initial point M(x m ,y m ) the farthest point N (x n ,y n );

[0042] (4) Establish the XMY plane Cartesian coordinate system for calculating the number of passes, and perform coordinate system transformation on the GPS data in the xOy plane Cartesian coordinate system;

[0043] (5) if Figure 5 As...

Abstract

The invention relates to a method for calculating construction times of a road roller. The method comprises the following steps: obtaining GPS (Global Position System) data; projecting all points in an XYZ coordinate system to an X axis or a Y axis so as to obtain points on the coordinate axis; arranging acquisition test points Lk with equal distances on the coordinate axis of a XMY rectangular plane coordinate system; judging whether coordinate values of coordinate points of adjacent time are distributed on both sides of the points Lk, if the arithmetic product is negative, commanding that the number of construction times of the road roller at the current section position Lk is equal to Bk+1; if the arithmetic product is positive, commanding that the number of construction times of the road roller at the current section position Lk is equal to Bk; judging whether Lk is the last section position, if yes, outputting the number of construction times of sections to be observed, else, continuing to calculate the construction times of the next section. The invention further discloses a system for calculating the construction times of the road roller. Through the adoption of the method and system, disclosed by the invention, large amounts of GPS data points collected for a long time can be processed and analyzed, and the construction times of the road roller traveling in uncertain to-and-fro paths can be calculated.

Description

technical field [0001] The invention relates to the technical field of road roller construction in road paving projects, in particular to a method and system for calculating the number of construction times of a road roller. Background technique [0002] The road roller is a kind of operation machine that uses the method of mechanical weight, vibration or impact to repeatedly load the compacted material, remove the air and moisture inside it, and make it reach a certain degree of compactness and flatness. At present, it is mainly used for compacting the foundation surface and road surface of highways, docks, airports and dams. During construction, it is often necessary to carry out road construction in both forward and backward directions. During the construction process, the road roller is always in vibration due to the construction requirements. state, which can easily lead to driver fatigue. [0003] The compactness and flatness of the road surface are important indicato...
