The invention provides a fiber grating intelligent bar and a manufacturing method thereof. The fiber grating intelligent bar comprises fiber gratings, an elastic material and a steel wire; the fiber gratings are bonded and fastened to the elastic material through an adhesive, the steel wire is provided with grooves, and the elastic material inside the grooves is bonded and fastened to the steel wire through the adhesive. According to the fiber grating intelligent bar and the manufacturing method thereof provided by the invention, the fiber gratings are firstly coupled with the elastic materialand are then coupled with the steel wire. Adverse effects caused by direct coupling of the fiber gratings and the steel wire are overcome, such as coupling under the condition of the stretched steelwire and low coupling survival rate, and meanwhile, the manufacturing efficiency of the fiber grating intelligent bar is improved.
