The second clamp 120 may be fastened to a second point of the track. The second clamp 120 may be designed to be substantially the same as that of the first clamp 110 .

The measuring unit 140 may apply a voltage or current to the first and second clamps 110 and 120 and measure a resistance value between the first and second clamps 110 and 120 based on the applied voltage or current. have.

For example, the measuring unit 140 may measure a resistance value by applying a voltage to the first clamp 110 and sensing a current through the second clamp 120 .

If the line between the first clamp 110 and the second clamp 120 is damaged, the resistance value measured by the measuring unit 140 may increase. The measurement unit 140 may accurately detect the change in the resistance value.

In general, since the specific resistance of the line is small, the difference in resistance value depending on whether the line is worn out may be small. Accordingly, the voltage (eg, 0.1V to 12V) applied by the measuring unit 140 may be relatively small, and the current (eg, 0.1mA to 20A) by the voltage may be large. For example, the measurement unit 140 may include circuits capable of improving the signal-to-noise ratio (SNR) through offset correction, gain amplification, and/or noise removal to detect a minute change in the measured resistance value.

The processing unit 150 may generate line wear information corresponding to a value relative to the reference value of the resistance value measured by the measurement unit 140 .
