The invention is suitable for the technical field of steel wires for bridge cables, and provides a manufacturing method of a special steel wire for remotely monitoring the operation state of a bridge cable, comprising the following steps: S1, surface treatment of a wire rod; s2, drawing is carried out; s3, grooving is carried out; s4, finishing is conducted; and S5, stabilizing treatment. The special steel wire is produced by selecting a hot-rolled wire rod and carrying out five steps of surface treatment, drawing, grooving, finishing and stabilizing treatment on the wire rod, the optical fiber is very conveniently implanted into a special groove of the special steel wire, and the problems that the operation of implanting the optical fiber into a stainless steel round steel pipe in a traditional process is difficult, and detection data is inaccurate due to the fact that the round steel pipe is prone to deformation are solved; according to the invention, the steel wire grooving adopts the front roller grooving
