Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of fiber cable cross connection box door opening state intelligent detection device, comprise metal bar 1, spring 2, permanent magnet A3, optical fiber 4, fiber grating 5, spring leaf 6 and permanent magnet B7, spring leaf 6 is arranged on the below of permanent magnet B7, fiber grating 5 is close to the below of spring leaf 6, and the two ends of fiber grating 5 and spring leaf 6 two ends are fixed together, namely fiber grating 5 is fixed between point of fixity A and point of fixity B.Metal bar 1 one end is connected with spring 2, and permanent magnet A3 is arranged on metal bar 1 is connected one end top with spring 2, and fiber grating 5 is connected with optical fiber 4.
Wherein, the thickness of spring leaf 6 is 0.15cm.Fiber grating 5 is connected with the mode of optical fiber 4 by welding.The track installing metal bar 1 is set in fiber cable cross connection box.
As shown in Figure 1, when fiber cable cross connection box is in pass door state, the door extrusion metal rod 1 of fiber cable cross connection box, Compress Spring 2, makes permanent magnet A3 and permanent magnet B7 be staggeredly located, does not produce attractive force between permanent magnet A3 and permanent magnet B7; As shown in Figure 2, when fiber cable cross connection box is in door opening state, metal bar 1 ejects by spring 2, and the permanent magnet A3 be fixed on metal bar 1 is moved forward, and permanent magnet A3 is corresponding with permanent magnet B7 position, makes to produce attractive force between permanent magnet A3 and permanent magnet B7; Between permanent magnet A3 and permanent magnet B7 under attractive force effect, permanent magnet B7 produces downward power thus compression spring leaf 6, makes the fiber grating 5 depended on spring leaf 6 be in extended state.
As shown in Figure 3, spring leaf 6 occurs to the raised deformation of a direction after being under pressure, this type of shape becomes elastic deformation, and think that the length of axis 9 does not change in change procedure, so think that the length of upper surface 8 shortens, and the length of lower surface 10, and fiber grating 5 is fixed in the lower surface of spring leaf 6, therefore when spring leaf 6 is extruded, fiber grating 5 is stretched.Thus change screen periods, cause the reflection wave centre wavelength of fiber grating 5 to change, can be arrived by remote monitoring.
Situation spring leaf being had press down, needing to produce magnetic force between permanent magnet could realize, and the magnetic force between permanent magnet also can by calculating.
According to elastic deformation by calculating the variable quantity that just can obtain fiber bragg grating center wavelength, as shown in table 1.
Table 1: spring deformation and the fiber bragg grating center wavelength change table of comparisons
At control end, detected by the wavelength of specialized equipment to fiber grating, thus reach optical cross box door opening state is monitored.
In sum, the present invention has following effect:
1, adopt passive mode to carry out intelligent decision to optical cross box door opening state, do not need extra power supply, solve the problem that conventional cable cross-connecting box gate control system needs power taking.
2, the acting force between magnet is utilized door opening state to be converted into spring and fiber grating deformation, the problem that fiber grating is broken by the impact avoiding metal bar in switch gate operation, long service life.
3, utilize fiber grating as sensor, there is passive, the advantage such as electromagnetism interference is strong, highly sensitive, corrosion-resistant, long service life.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
