LIS
Automatic Road Marking Repeating System
THIN-LAYER PAINT MARKING
The device for automatic repetition of road markings “LIS” (laser intelligent system) is designed for use as part of road marking machines and serves for the automatic repetition of longitudinal horizontal road markings.
Using the LIS system improves productivity and the quality of road marking work, facilitating the work of the driver and operator. The LIS system is a complete set of equipment installed on a road marking machine during production or upgrades. It includes a control terminal, a control cabinet with electronic modules, a laser scanner, and a video camera. The painting module is moved by an electric or hydraulic linear drive.
“LIS” DEVICES ARE USED TO WORK IN THE FOLLOWING MODES:
- automatic repetition of previously applied markings;
- semi-automatic repetition of previously applied markings;
- manual;
- automatic application of new markings.
The operation of the LIS device in automatic and semi-automatic modes is based on determining the coordinates of the lines of the previous markings (using a laser scanner and a video camera), guiding the MDR painting module to the marking lines and controlling the painting process.
The LIS device operates in manual mode when the operator guides the painting module to the marking lines using the control terminal elements and controls the painting process manually.
The LIS device operates in automatic mode for applying new markings with the paint module’s aiming mode on the old markings disabled.
