Abstract

The invention relates to a speed measurement device for improving the paving quality of a paver and a speed measurement method. The speed measurement device comprises a speed measurement wheel, a Hallrotation sensor and a microcontroller, wherein the speed measurement wheel is set on the side surface of the paver, and the speed measurement wheel is contacted with the ground when the paver moves and rotates under the action of friction; the paver is provided with the microcontroller, the speed measurement wheel is provided with the Hall rotation sensor, and the Hall rotation sensor is connected with the microcontroller and transmits turn number data collected by the Hall rotation sensor to the microcontroller. The speed measurement device for the paver further transmits the paver driving displacement and real-time speed calculated by the microcontroller to external mobile intelligent terminal equipment such as a mobile phone and a pc through a wireless communication module so as to timely grasp and record speed operation conditions of the paver by using terminal applications.

Description

technical field [0001] The invention belongs to the field of engineering machinery, in particular to a speed measuring device and a speed measuring method for improving the paving quality of a paver. Background technique [0002] With the development of basic road paving construction, the relevant departments of road inspection and acceptance put forward higher requirements for the construction technology and acceptance indicators of the road, and the requirements for the compactness, uniformity, and flatness of the road surface are getting higher and higher. The accuracy of the speed measurement of the paver is very important to the paving quality of the paver. [0003] In the existing technical solutions, most of the modern paver installs a speed sensor on the walking hydraulic motor, compares the detected speed signal with the set speed, and then outputs the signal to control the walking variable pump, so that the paving can be carried out at any time. The operating spee...
