The Overhead Measuring System verify the wire geometry as the Y-coordinate or stagger, and Z-coordinate or height, relative to the track.
The wire position reference is relative to the track center, for the horizontal axis, and to the rolling plane for the vertical axis.
Technology: Rotating laser scanner
The rotary scanner uses reflective laser technology and determines the distance from the center of any obstacle in the surroundings of 10-15m, enough to detect the contact wires, multiple wires simultaneously. The scanner itself must detect and measure the position of the rails to report the wire and calculate stagger and height.
Proprietary algorithms have been implemented to minimize or eliminate the environmental events, such as sun, rain, and fog that can affect this technology.
Technology: Radar scanner
The radar applied to the wire measurement is the cutting-edge technology in the railway field. This product is conceived for non-attended applications because the wire detection is not affected by any disturbance of the sun or rain. No maintenance is required to maximize uptime.
Completeness of the data: It measures multiple wires simultaneously including the catenary.
Increased accuracy can be reached coupling it with a Rail Profile Measuring System.
