Paving operation speed measuring method for paver

Abstract

The invention provides a paving operation speed measuring method for a paver. The method comprises the steps of S1, establishing a paver construction plane coordinate system, and initializing a sampling frequency of a GPS receiver; S2, in an operation process of the paver, sequentially collecting longitude and latitude coordinates of the position of the paver by the GPS receiver according to the sampling frequency; S3, converting the longitude and latitude coordinates obtained at a current sampling time point to the paver construction plane coordinate system so as to obtain current construction plane coordinates; S4, calculating current operation speed of the paver according to the current construction plane coordinates, construction plane coordinates at a previous sampling time point andthe sampling frequency; and S5, repeating the steps S2 to S4 until the paver stops operation. A paver construction plane coordinate model is built, and an accurate calculation model of the paving speed of the paver is built, so that the change of the paving speed can be conveniently discovered in time to adjust the paving operation speed for ensuring the paving quality, the adaptability is high, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of paver control, in particular to a speed measurement method for paver paving operations. Background technique [0002] Nowadays, the construction speed of high-grade highways is getting faster and faster. As the key equipment for building various grades of highways, paver not only requires high production efficiency, but also higher paving quality. In the actual paving construction process, the construction efficiency and construction quality of the paver are affected by multiple factors, such as the body structure parameters of the paver, construction operation parameters, paving speed, paving track, paver productivity, temperature of the mixture, etc. Among them, the paving speed directly affects the smoothness of the road surface. The paving speed should be maintained at a constant speed, ranging from 2 to 6m / min. If the paving speed is unstable or exceeds the normal paving speed range, it will lead ...

AI Technical Summary

Problems solved by technology

If the paving speed is unstable or exceeds the normal paving speed range, it will lead to uneven paving of the mixture, resulting in wavy undulations on the road surface and affecting the smoothness

Usually, when the paver is in construction, its paving speed is determined by the driver, and the paving speed cannot be timely fed back, and the paving speed of the paver cannot be monitored and adjusted in time, so that The paving quality of the pavement cannot be guaranteed
