Intelligent steel strand with built-in sensor and manufacturing method of intelligent steel strand

The intelligent steel strand comprises side steel wires and a center steel wire, the diameter of a center hole of the center steel wire is not larger than 1 mm, the sensors are fixed in the center hole, the center hole of the center steel wire is a through hole penetrating through the two end faces of the steel wire, and the sensors are distributed in the center hole of the center steel wire. The sensors are one of three modes of optical fibers, optical fiber gratings, carbon fiber rods or steel wire fixing strain gauges, the number of the sensors in the sensor assembly is n, n is larger than or equal to 1, and the sensors are arranged at intervals or continuously; the sensor assembly is implanted into a center hole of the traditional Chinese medicine steel wire in a traction rope traction mode, an air blowing mode or a traction rope traction and air blowing combined mode and then is fixed through a binding agent. The device has the advantages that the sensor component is positioned in the central hole of the
