Automatic road marking pre-marking equipment and working method

Abstract

The invention discloses automatic road marking pre-marking equipment and a working method. The automatic road marking pre-marking equipment comprises a self-walking trolley, a laser radar, an external interaction terminal, a GNSS fixed station and a GNSS mobile station, wherein the laser radar and the GNSS mobile station are fixed on the self-walking trolley; the external interaction terminal is in interactive communication with the self-walking trolley, the laser radar, the GNSS fixed station and the GNSS mobile station; the GNSS fixed station and the GNSS mobile station carry out interactive communication, and accuracy of pre-scribing positioning is guaranteed. According to the positioning information and the set scribing rule, the arranged spraying head can conduct automatic spraying and scribing according to the scribing path according to the scribing rule, automatic pre-scribing is achieved, labor cost is reduced, and pre-scribing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, and more specifically relates to a road marking automatic pre-marking device and a working method. Background technique [0002] At present, there are various indicative markings on all kinds of highways in our country, such as Figure 4 As shown, these markings are basically done manually. The workflow of its marking is basically as follows: First, workers pre-mark according to the construction drawings, such as Figure 5 The thin line shown, where, because the marking line may be a dotted line, a mark needs to be made on the pre-marked line, marking the starting point and end point of the marking line; then, according to the pre-marked line, the worker adopts figure 2 device, draw the final marking line (thick line), the specific method is: figure 2 A 6-8mm diameter guide steel needle is installed on the front of the device. The worker aligns the needle with the pre-scribing line,...

Problems solved by technology

However, most of the existing marking equipment uses GPS for positioning and spraying for marking. At the same time, it combines manual positioning position determination and marking control, so the positioning accuracy is not high and the marking position is not accurate. , Cannot be used in scenes with weak GPS signals, unclear marking lines, labor-intensive and low work efficiency, etc.
