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

[0032] Such as figure 2 As shown, a method for calculating the number of constructions of a road roller includes the following steps:

[0033] (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 proceed to the next step; otherwise, delete the invalid data;

[0034] (2) Convert the longitude and latitude coordinate data in the stored GPS data from the WGS-84 spherical coordinate system to the plane rectangular coordinate system xOy;

[0035] (3) Based on the time sequence of data storage, select the initial point M(x m , Y m ), and calculate the initial point M(x m , Y m ) The farthest point N(x n , Y n );

[0036] (4) Establish the XMY plane rectangular coordinate system for calculating the number of passes, and perform coordinate system transformation on the GPS data in the xOy plane rectangular coordinate system;

[0037] (5) such as Figure 5 As shown, all points in the XMY plane rectangular coor...

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 for calculating the number of road roller constructions. Background technique [0002] A road roller is a kind of work machine that uses mechanical weight, vibration or impact to repeatedly load the material to be compacted to remove the air and moisture inside to achieve a certain degree of compactness and flatness. At present, it is mainly used for foundation surface and road surface compaction operations of highways, docks, airports, and dams. During construction, it is often necessary to carry out road roller construction in both forward and backward directions. The roller has been vibrating during the construction process due to construction requirements. State, easily lead to driver fatigue. [0003] The compactness and flatness of the road surface is an important indicator that must be inspected during road construction, quality ...
