Wire laying system and monitoring method thereof

The invention relates to a wire laying system and a monitoring method thereof, the wire laying system comprises a paying-off tackle (10), a stretching machine (20) and a background system (30) for controlling the stretching machine to work, the paying-off tackle comprises a support (1), a traction wheel (3) rotatably installed in the middle of the support through a center shaft (2) and wire pulleys (4) arranged on the two sides of the traction wheel side by side; laser range finders (5) emitting laser beams to the support are installed on the two wire pulleys, the support is of a door frame structure, and when the laser range finders rotate along with the wire pulleys, the distance between the laser beams of the laser range finders and the door frame part and the distance between the laser beams of the laser range finders and the spare part change suddenly. By adopting the wire laying system and the monitoring method thereof, the background system can more accurately and timely monitor the fault condition of
