、遮断桿６の損壊事故を即時に検知しうる。FIG. 1 is a perspective view showing an embodiment of the present invention, in which an optical fiber 2 folded into a beam shape is covered with a tape 3 having an adhesive layer 4 on at least the negative side. In order to immediately detect, for example, a breakage accident of a barrier of an unmanned railroad crossing using the optical fiber-containing adhesive tape,
As shown in FIG. 2, the optical fiber-containing adhesive tape 1 is wrapped around the cutoff rod 6 and attached, and one end of the optical fiber 2 is connected to the projector 7 and the other end to the monitor 8 to monitor the normal optical power. be monitored. Therefore, if the cutoff rod 6 is damaged due to some kind of accident, the optical fiber 2 of the optical fiber-containing adhesive tape 1
Since the shielding rod 6 breaks in one piece and the monitored optical power decreases, a breakage accident of the shielding rod 6 can be immediately detected.

える。FIG. 3 shows another embodiment of the present invention in which an optical fiber 2 folded in a U shape is covered with a tape 3 having an adhesive layer 4 on at least one surface, and connectors are attached to both ends of the optical fiber 2. This is a perspective view showing an example. By attaching connectors 5.5 to both ends of the optical fiber 2, the connection work between the optical fiber 2, the projector 7, and the monitor 8 can be performed extremely smoothly.
