Monitoring device for road roller

Abstract

The invention discloses a monitoring device for a road roller. The monitoring device comprises a remote data extraction device, a server and a computer, wherein the remote data extraction device is arranged in a driving cab of the road roller and internally comprises a singlechip, a global positioning system (GPS) locating module and a wireless data transmission module. The remote data extraction device is used for transmitting the coordinate of longitude and latitude corresponding to the position where the road roller is positioned to the server at the interval of 10 seconds by the wireless data transmission module; the coordinate of longitude and latitude of a center line of the subgrade of a highway planned to be built is stored in a database of the server; the server is used for automatically calculating the subgrade compaction times according to the coordinate of the position where the road roller is positioned, acquired by the remote data extraction device, and the coordinate of the center line of the subgrade. The real-time statistics results are stored in the database by the server and are browsed by a user through an internet explorer (IE). The monitoring device can be used for carrying out automatic and accurate statistics on the subgrade compaction times of all the parts in the railway construction process, monitoring the specific locations of all road rollers in real time, and carrying out playback on the work trajectories of the road rollers, thus guaranteeing the construction quality.

Description

technical field [0001] The invention relates to the technical field of traffic construction information management, in particular to a road roller monitoring device. Background technique [0002] In the process of expressway laying, the number of compaction times and compaction uniformity of subgrade are directly related to the quality of the project. In the current operation process of the road roller, it mainly relies on the working experience of the operator, and it is prone to pressure leakage and overpressure. Usually, after the completion of each layer, it is also necessary to use the method of point sampling to test the compactness of the road surface. Such a workflow has the problems of long detection period, and the detection results cannot truly reflect the compaction quality of the whole road section. It also has the disadvantages of incomplete data, random sampling, point-by-point generalization, insufficient precision, and insufficient extensiveness. Existing ...

Problems solved by technology

This kind of workflow has the problems of long detection period, the detection results cannot truly reflect the compaction quality of the whole road section, and there are also shortcomings such as incomplete data, random sampling, point-by-point generalization, insufficient precision and insufficient extensiveness.

Existing inspections are post-construction inspection measurements. Failure to meet the standards will lead to rework, resulting in higher costs and the risk of over-compaction
