Description

Technical Field

[0001] The present application relates to the field of sensor technology, and in particular to a deformation-conducting optical fiber sensor and a sensor system. Background Art

[0002] For monitoring of building structures, landslides and other deformations involving bending, stress and other deformations, traditional sensors can usually only be used for monitoring at local locations, and cannot achieve large-scale distributed measurement, and are prone to ignoring potential problems in other parts of the structure. The deployment of a large number of sensors and their connecting cables in large building structures not only increases the difficulty and cost of installation, but may also cause electromagnetic interference problems, affecting the accuracy of the data. In harsh environments, the service life of traditional sensors is limited, and frequent maintenance and replacement increase operation and maintenance costs. Based on the above background, there is an urgent need for a new type of monitoring technology that can overcome the limitations of traditional sensors. The purpose of the present invention is to provide a deformation conduction optical fiber sensor and a sensing system for monitoring building structures, landslides and other deformations involving bending, stress and other deformations, so as to solve the problems existing in the prior art such as limited monitoring range, complex wiring, and easy damage of sensors. Summary of the Invention

[0003] The present application provides a deformation-conducting optical fiber sensor and a sensor system, which uses a sensor conduction component to cause the optical fiber to change its shape as the shape of the object being measured changes, and measures the deformation data of the object being measured based on the change.

[0004] In a first aspect, the present application provides a deformation-conducting optical fiber sensor that is mounted on an object to be measured. The deformation-conducting optical fiber sensor includes a sensor conversion assembly, a sensor conduction assembly, and an instrument. The sensor conversion assembly includes a main body, an optical fiber mounted on the main body in a preset configuration, and a transmission member, one end of which is fixed to the object to be measured. The sensor conduction assembly is mounted on the main body and fixed to the other end of the transmission member. When the configuration of the object to be measured changes, the sensor conduction assembly causes the configuration of the optical fiber to change. An instrument (such as an OTDR) is connected to one end of the optical fiber to sense the configuration change of the optical fiber and calculate measurement data representing the configuration change of the object to be measured based on the configuration change of the optical fiber.

[0005] In a second aspect, the present application provides a sensor system comprising a plurality of the above-described deformation-conducting optical fiber sensors connected in series. Each deformation-conducting optical fiber sensor can independently sense morphological changes of a measured object, allowing the sensor system to extend its coverage to a wider monitoring range.

[0006] The aforementioned deformation-conducting fiber optic sensor and sensor system uses a sensor transmission component to sense changes in the measured object's shape, causing the optical fiber to deform accordingly. By sensing the optical fiber's deformation, the instrument accurately calculates displacement changes, such as stretching and compression, occurring in the measured object, thereby providing high-precision deformation measurement.

[0022] Please see Figure 1 , Figure 1A schematic diagram of a deformation-transmitting fiber optic sensor provided in an embodiment of the present application. This application provides a deformation-transmitting fiber optic sensor 99. This deformation-transmitting fiber optic sensor 99 senses a measured object (not shown). The deformation-transmitting fiber optic sensor 99 comprises a sensor conversion assembly 1, a sensor transmission assembly 2, and an instrument 4. The sensor conversion assembly 1 is connected to the sensor transmission assembly 2 and the instrument 4. The sensor conversion assembly 1 includes an optical fiber 5 mounted in a predetermined configuration. When the measured object changes in configuration, the sensor transmission assembly 2 causes the optical fiber to change its configuration. The instrument 4 is connected to one end of the optical fiber 5 and senses the change in configuration of the optical fiber 5 and calculates measurement data representing the change in configuration based on the change in configuration of the optical fiber 5. In this embodiment, the measured object can be a building, a slope, or other object to be monitored. When the measured object changes in configuration, such as when the measured object is stretched or compressed, the deformation-transmitting fiber optic sensor 99 causes the optical fiber 5 to change its configuration. This change in configuration is then converted into an optical signal, i.e., measurement data representing the change in configuration of the measured object.

[0023] The sensor conversion assembly 1 includes a main body, an optical fiber 5 installed on the main body in a preset shape, and a transmission member 25. One end of the transmission member 25 is fixed to the object to be measured. The transmission member 25 is a transmission rod or a transmission line. In this embodiment, the optical fiber material can be either a single-mode optical fiber or a multi-mode optical fiber according to the use requirements. Specifically, the morphological changes of the object to be measured include tensile deformation and compressive deformation. When the object to be measured undergoes tensile deformation, the transmission member 25 is in a tensile state and applies a force to the sensor transmission assembly 2, causing the sensor transmission assembly 2 to move along a first direction and causing the optical fiber 5 to undergo a first deformation; when the object to be measured undergoes compressive deformation, the transmission member 25 is in a relaxed state, so that the force applied to the sensor transmission assembly 2 is released, causing the sensor transmission assembly 2 to slide in a second direction opposite to the first direction and causing the optical fiber 5 to undergo a second deformation. Furthermore, when the light incident from the light source of instrument 4 is sent into instrument 4 via the scattered light generated by optical fiber 5, the shape of the object being measured changes, causing optical fiber 5 to change, which in turn causes the optical properties of the light sent into instrument 4, such as the intensity, wavelength, frequency, phase, polarization state, etc. of the light, to change, thereby obtaining measurement data.

[0024] Please see Figure 2-Figure 3 The main body is generally a hollow rectangular body with an opening. The main body is provided with a first receiving cavity 13 and two second receiving cavities 14 located at either end of the first receiving cavity 13. The first receiving cavity 13 and the two second receiving cavities 14 are connected to the opening. The main body is provided with a mounting structure for the optical fiber 5, which covers the opening.

[0025] The main body is also equipped with a fiber mounting structure 16 and a cover plate 15. The first and second cable troughs 11, 12 are symmetrically arranged along the length of the main body and are used to accommodate the optical fibers 5. The main body is also equipped with a cover plate 15 that covers the first and second receiving cavities 13, 14.

[0026] More specifically, the main body further includes a fiber optic mounting structure 16 located below the cover 15 and covering the first receiving cavity 13. The first and second cable troughs 11, 12 are disposed within the fiber optic mounting structure 16. The main body further includes a sealing ring 18 disposed around the edge of the main body's top surface. When the cover 15 passes through a fixture (not shown), the sealing ring 18 is squeezed between the cover 15 and the main body, causing it to deform, thereby providing an effective seal for the deformation-conducting fiber optic sensor 99.

[0027] Please see Figure 4-Figure 7 Specifically, the optical fiber mounting structure 16 includes a first optical fiber mounting structure 160 and a second optical fiber mounting structure 162, which are arranged opposite each other. The second optical fiber mounting structure 162 is arranged opposite the cover plate 15, while the first optical fiber mounting structure 160 is spaced apart from the cover plate 15. A first sliding groove 1604 is provided in the middle of the first optical fiber mounting structure 160 along its width, and an opening 1602 is provided at the bottom of the first sliding groove 1604. A pair of longitudinally extending protrusions 164a and 164b are provided at both ends of the opening 1602. In other words, the first optical fiber mounting structure 160 has two pairs of protrusions 1604a and 1604b. Each pair of protrusions 1604a and 1604b is provided with a plurality of first latching blocks 1606a and a plurality of second latching blocks 1606b, respectively. The first optical fiber mounting structure 160 also has a longitudinally extending sliding groove 1608 between the pair of protrusions 1604a and 1604b.

[0028] The second fiber optic mounting structure 162 conforms to the first fiber optic mounting structure in appearance. The second fiber optic mounting structure 162 interlocks with the first fiber optic mounting structure 160. A second slider groove 1622 is provided on the second fiber optic mounting structure 162 at a position corresponding to the first slider groove 1604. The first and second fiber optic mounting structures 11 and 12 are disposed on the second fiber optic mounting structure 162 and correspond to the protrusions 1604a and 1604b. The protrusions 1604a and 1604b are embedded in the first and second fiber optic mounting structures 11 and 12. A reset hole 1623 extends through the second fiber optic mounting structure 162.

[0029] The second optical fiber mounting structure 162 is provided with a plurality of first clamping blocks 1606a and a plurality of second clamping blocks 1606b. These first clamping blocks 1606a and a plurality of second clamping blocks 1606b on the second optical fiber mounting structure 162 are interlaced with the first clamping blocks 1606a and a plurality of second clamping blocks 1606b on the protruding strips 1604a and 1604b. The optical fiber mounting structure 16 is provided with a first cable trough 11 and a second cable trough 12. The optical fiber mounting structure 16 also includes two first trough walls that enclose the first cable trough 11 and two second trough walls that enclose the second cable trough 12. The two first trough walls are each provided with a plurality of first clamping blocks 1606a that protrude into the first cable trough 11. The two second groove walls are each provided with a plurality of second clamping blocks 1606b protruding toward the second cable groove 12. The plurality of first clamping blocks 1606a are arranged in a staggered arrangement, and the second clamping blocks 1606a are arranged in a staggered arrangement. The optical fibers 5 located in the first and second cable grooves 11, 12 are abutted by the first and second clamping blocks 1606a, 1606b, thereby being restrained in a curved shape within the first and second cable grooves 11, 12. It is understood that the optical fiber mounting structure 16 can be manufactured as a single unit. The portions of the first and second clamping blocks 1606a, 1606b that abut the optical fibers 5 are curved surfaces.

[0030] Please see again Figure 3 The main body includes a first cavity wall 130 that surrounds the first accommodating cavity 13. The first cavity wall 130 includes two end walls 1301a and 1301b shared by the first accommodating cavity 13 and the second accommodating cavity 14. The end walls 1301a and 1301b are provided with a groove 13010.

[0031] Please refer to Figure 8 and Figure 9 The sensor conductive component 2 includes an elastic sliding body slidably mounted on the main body, and a slide groove and an optical fiber deformation structure provided on the elastic sliding body. The elastic sliding body includes a sliding body 23 and an elastic member 24 slidably mounted in the main body. The elastic member 24 and the sliding body 23 are accommodated in the first accommodating cavity 13, so that the elastic member 24 is confined between one end of the sliding body 23 and the side of the main body facing the sliding body 23. In the initial state, the elastic member 24 is in a deformed state and accumulates elastic force. The optical fiber deformation structure includes a first slider 21 and a second slider 22 arranged along the width direction of the main body.

[0032] The sliding body 23 is provided with a first slide groove 230 and a second slide groove 232. The first slider 21 and the second slider 22 are slidably mounted in the first slide groove 230 and the second slide groove 232, respectively. When the object to be measured changes or the main body becomes loose, the transmission member 25 is stretched and drives the sliding body 23 to slide in the first direction or the second direction, that is, to slide along the length direction of the main body. When the sliding body 23 slides, the first slider 21 or the second slider 22 slides under the restriction of the first slide groove 230 or the second slide groove 232 and protrudes toward the first wire groove 11 or the second wire groove 12 to apply force to the optical fiber 5 in the first wire groove 11 or the optical fiber 5 in the second wire groove 12, so that the optical fiber 5 is converted from the first curvature to the second curvature. The first curvature and the second curvature are used for the sensor component 4 to calculate measurement data based on the first curvature and the second curvature.

[0033] The sliding body 23 comprises a base 233, a sliding portion 234 mating with the base 233, and a one-way thread lock 235. The base 233 is fixedly connected to one end of the transmission member 25. A top plate (not shown) is provided on the side of the sliding portion 234 facing away from the base 233. The first and second slide grooves 230 and 232 are disposed on the top plate. The sliding body also includes a connecting portion (not shown) located between the base 233 and the top plate. The connecting portion comprises a rectangular side plate 2360 extending from the edge of the top plate. The base 233 is mated with the connecting portion and disposed opposite the top plate. The sliding body 23 has a roughly horizontal B-shaped cross-section. The base 233 and the connecting portion are hollow square bodies with an upper opening. The top plate covers the opening and is significantly longer than the base 233. A protruding post (not shown) is provided on the side of the top plate facing away from the base 233. The protruding post is inserted into the sliding groove 1608. The one-way wire lock 235 is disposed on the base 233 and locks to the transmission member 25. The one-way wire lock 235 includes a locking buckle 2350 that corresponds to the reset hole 1623. In this embodiment, the transmission member 25 can be a steel wire or a steel bar. The one-way wire lock 235 restricts the transmission member 25 from moving only in a first direction. The locking buckle 2350 is pressed by a user through the reset hole 1623 with a tool, allowing the transmission member 25 to move in both the first and second directions. This allows the length of the transmission member 25 in the main body to be adjusted, thereby ensuring that the deformation conductive optical fiber sensor 99 can be reused and facilitates maintenance.

[0034] The first chute 230 includes a first straight segment 230a, a first folded segment 230b, and a second folded segment 230c, which are sequentially arranged. The second chute 232 includes a second straight segment 232a and a third folded segment 232b, which are sequentially arranged. The second straight segment 232a is opposite the first straight segment 230a. The third folded segment 232b is opposite the first folded segment 230b and the second folded segment 230c. The first folded segment 230b and the third folded segment 232b have similar bending angles and bend toward the first linear chute 11. The second folded segment 230c is bent toward the second linear chute 12 relative to the first folded segment 230b.

[0035] The first and second sliders 21 and 22 have identical structures, comprising sliding posts 212 and 222, respectively, and a push-up portion. The sliding post 212 of the first slider 21 extends vertically from one side of the push-up portion. The push-up portion, facing away from the sliding post 212, is provided with first and second stoppers 214 and 215, respectively, and a stopper slot 216 located between the first and second stoppers 214 and 215. The sliding post 222 of the second slider 22 extends vertically from one side of the push-up portion. The push-up portion, facing away from the sliding post 222, is provided with first and second stoppers 224 and 225, respectively, and a stopper slot 226 located between the first and second stoppers 224 and 225. The optical fibers 5 located in the first and second cable ducts 11 and 12 can be operatively positioned within the stopper slots 216 and 226 of the first or second sliders 21 and 22, respectively.

[0036] During the measurement process, when the measured object changes, the transmission member 25 is subjected to force, pulling the sliding body 23 in a first direction, thereby causing the first and second sliders 21 and 22 to slide toward the first trough 11. This causes the optical fiber 5 located in the first trough 11 to be pulled, causing the curvature to change from the first curvature to the second curvature, and the change in curvature is measured by the sensor assembly 4. When the deformation transmission optical fiber sensor 99 loosens, the elastic member 24 releases its elastic force, causing the sliding body 23 to slide in a second direction opposite to the first direction, causing the first and second sliders 21 and 22 to slide toward the second trough 11. This causes the optical fiber 5 located in the second trough 11 to be pulled, causing the curvature of the optical fiber 5 to change from the first curvature to the second curvature, and the change in curvature is measured by the sensor assembly 4. It is understood that the second curvature merely indicates a difference from the first curvature and is not limited to a specific value. That is, the second curvatures of the optical fibers 5 located in the first and second troughs 11 and 12 after the change can be different or the same, and this is not limited here. The first curvature only represents the initial curvature of the optical fiber 5 located in the first wire groove 11 and the second wire groove 12, and does not represent a specific value. That is, the initial curvature of the optical fiber 5 located in the first wire groove 11 and the second wire groove 12 can be different or the same, and is not limited here.

[0037] In this embodiment, the deformation-conducting fiber optic sensors 99 can be deployed in different configurations depending on the sensing scenario. Different numbers of deformation-conducting fiber optic sensors 99 can be deployed based on these configurations, thereby determining different fiber material placement patterns. For example, when the sensing scenario is a single, easily deformed location on a building, such as a wall edge, a single-point deployment can be employed. Specifically, after analyzing the deformation-prone locations, the deformation-conducting fiber optic sensors 99 can be deployed directly with the corresponding fiber material at those locations. For another example, when the sensing scenario involves long sensing distances and large areas, such as slopes or perimeter security, a multi-point or distributed deployment can be employed. The number of deformation-conducting fiber optic sensors 99 can be determined based on the area of ​​the slope sensing scenario or the sensing boundary of perimeter security. The corresponding fiber material placement pattern can then be determined based on the placement of the deformation-conducting fiber optic sensors 99.

[0038] In some feasible embodiments, after the deformation-transmitting optical fiber sensor 99 is deployed, to extend its service life and reduce component replacement costs, it is also necessary to consider the environmental factors of the sensing scenario in which the deformation-transmitting optical fiber sensor 99 is deployed, and to implement measures to ensure that the deformation-transmitting optical fiber sensor 99 is sufficiently resistant to these environmental factors. For example, when the sensing scenario is corrosive, to enhance the corrosion resistance of the deformation-transmitting optical fiber sensor 99 in such a corrosive environment, appropriate corrosion-resistant coatings and components may be added to the outer shell and internal components of the deformation-transmitting optical fiber sensor 99 to enhance its corrosion resistance.

[0039] Please refer to Figure 10 , which is a schematic diagram of sensor system 999. Sensor system 999 includes multiple deformation-conducting fiber optic sensors 99 and a sensor assembly 4. The number of deformation-conducting fiber optic sensors 99 can be set according to actual needs. For example, the wider the measurement range, the more deformation-conducting fiber optic sensors 99 are required. The multiple deformation-conducting fiber optic sensors 99 are connected in series via a transmission member 25 and an optical fiber 5. For the specific structure of the deformation-conducting fiber optic sensor 99, please refer to the deformation-conducting fiber optic sensor 99. The difference is that the deformation-conducting fiber optic sensor 99 at the head end of the multiple deformation-conducting fiber optic sensors 99 is connected to the sensor assembly 4 via an optical fiber 5. In other words, the multiple deformation-conducting fiber optic sensors 99 share a single sensor assembly 4.

[0040] In the above embodiment, when the shape of the object to be measured is changed by the sensor conduction component, the shape of the optical fiber is also changed, so that the measurement data of the change in the shape of the object to be measured can be calculated by the sensor component, thereby measuring the tensile and compression length values ​​of the object to be measured, solving the problem of the object to be measured directly acting on the optical fiber, and avoiding the situation of optical fiber dislocation and breakage.

[0041] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Therefore, all modifications and variations within the scope of the claims of this application and their equivalents should be deemed to be included in the scope of protection of this application.

[0042] The above examples are merely preferred embodiments of the present application and are not intended to limit the scope of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope of the present application.
