AI Technical Summary
Conventional methods for tracing vehicle paths using magnetic markers or tape are limited by distance and magnetic decay, leading to difficulties in accurately reading and tracing lines at greater distances, especially with varying vehicle heights.
Creating a line tracing method using magnetic paint that alternates north and south poles to form a striped pattern, allowing for polarity-based line detection.
Enables accurate tracing of lines at greater distances by distinguishing the line center through polarity patterns, overcoming limitations of magnetic strength decay.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a method for manufacturing a line tracing wire. [Background technology]
[0002] Conventional technology involves using magnetic markers to trace the line of a transport vehicle. Using magnetic markers makes it possible to trace lines even on snowy roads. However, this method is costly because it requires the work of embedding the magnetic markers. Therefore, an alternative method is to use magnetic tape. However, because the strength of the magnetism decays in proportion to the square of the distance, this method can only create self-driving vehicles with a low minimum vehicle height. Conventional technology involves making the line tracing line into a striped pattern, etc. However, even if the pattern is striped, a magnetic resistance sensor will recognize it as a single line if the distance is large.

[0007] By preparing a line with alternating north and south poles, a line can be prepared that is judged by polarity rather than magnetic strength. As the distance increases, it becomes difficult to determine where the center of the original line is, but by making the polarity a striped pattern, it becomes easier to determine the center of the line even at a distance, making line tracing easier.
[0008] According to the effect of the present invention, it is possible to trace lines that are farther away than before. [Example]
[0009] A striped pattern of line tracing lines is drawn using magnetic paint, and one or more adjacent lines are magnetized so that their polarity is different. [Explanation of symbols]
