The second clamp 120 may be fastened to the second point of the track. The second clamp 120 may be designed to be substantially identical to the first clamp 110. [

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

For example, the measurement 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 worn, the resistance value measured by the measuring unit 140 may be large. The measuring unit 140 can accurately detect a change in the resistance value.

Generally, since the resistivity of the line is small, the difference in resistance value depending on whether or not the line is worn can be small. Therefore, the voltage (e.g., 0.1 V to 12 V) applied by the measuring unit 140 may be relatively small, and the current due to the voltage (e.g., 0.1 to 20 A) 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 a reference value of the resistance value measured by the measuring unit 140. [
