RTK based spreading work state monitoring system and method

Abstract

The invention discloses an RTK based spreading work state monitoring system and method. The system comprises an RTK positioning device for obtaining real-time position information of current work and generating real-time spreading speed information; a data acquiring card for converting the spreading speed information obtained by the RTK positioning device into speed units; a display for displaying the current spreading speed in real time; a wireless network module, consisting of a positioning receiving antenna and a GPRS antenna, for transmitting the positioning information of a spreading machine to a network server and obtaining the work pile number of the current spreading machine based on the established WGS84 coordinate and the engineering independent coordinate conversion reference table; and a master control machine for controlling the RTK positioning device, the positioning receiving antenna, the GPRS antenna, the data acquiring card and the display to work as well as processing data. The system and the method are able to obtain information on the spreading speed, the spreading position, and the work pile numbers of the starting point and the ending point of spreading, making them with great prospects for use in the future.

Description

technical field [0001] The invention relates to the technical field of pavement engineering, in particular to an RTK-based paving operation state monitoring system and method. Background technique [0002] Among the many construction procedures of asphalt pavement engineering, paving is undoubtedly a relatively important link. The quality of paving can ensure the smoothness and uniformity of the road surface. Among them, the paving speed is an important parameter affecting the quality of the pavement. If the paving speed If it is too fast, the vibration level efficiency of the tamper will be reduced and an effective initial compaction degree of the road surface cannot be formed; if the paving speed is too fast, it will affect the smoothness of the road surface, and the shutdown during construction (paving speed is 0), and It will affect the loss of the temperature of the mixture at the stop, which will cause insufficient compaction of the road surface and reduce the quality ...

Problems solved by technology

However, at this stage, there is no effective information collection method for the operation status of pavement paving. It completely relies on manual side station supervision and manual daily report statistics, which cannot achieve timeliness and accuracy.

[0003] At present, the utility model patent with the application number "201320846272.4" discloses "an intelligent control device for road paving and rolling engineering quality based on the Internet of Things", which proposes speed detection through Hall sensors, and Beidou positioning and gyroscope For positioning, because the Hall sensor must be installed with magnetic parts on the driving wheels, the installation work is complicated, and because the paving speed value is low (generally 1-3m / min), the acquisition frequency of the Hall sensor is low (number Acquisition once per minute), while the Beidou and gyroscope perform mechanical positioning, the positioning accuracy is not disclosed in the patented method, but from the perspective of still needing to install a Hall sensor for speed measurement, its acquisition frequency and positioning accuracy are limited
