Partial parameters.But Bragg optical-fiber grating sensor belongs to single-point monitoring sensor, although string can be organized, group string work
Limited amount larger, and that string can be organized is measured, is not suitable with for large-scale sensor monitoring.
Dim light grid array technology by the way of time division multiplexing is combined, realizes the multiple optical fiber of single channel using wavelength-division multiplex
Grating sensor monitors simultaneously.In application process, dim light grid array optical fiber directly applies to reality as that need to be prepared into cable manufactures
Border project, there is multiple technological problemses such as encapsulation, protection, fixed, spacing, it can not such as be given in dim light grid array sensing optic cable
Give the protection and support of fiber grating sufficient intensity, grating in itself in use will it is for example micro-bend by extraneous factor, shake
Dynamic wait influences and causes monitoring result misalignment.Traditional cable sleeve, modeling pipe production technology and structure type can not meet dim light
The application demand of grid array sensing optic cable.
Utility model content
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided the light of dim light grid array for sensor monitoring
Cable structure, it can solve the problems, such as protection, positioning, the support of fiber grating in dim light grid array sensing optic cable cable core, Jin Erti
High monitoring effect, and with anti-micro-bend, antivibration function.
What the purpose of this utility model was realized in：
A kind of cable configuration of dim light grid array for sensor monitoring, it includes inscribing the optical fiber for having dim light grid array,
Hard-pressed bale and is enclosed on the stainless steel tube of the C-shaped outside protective layer, at multiple positions on the optical fiber in the protective layer of outer fiber
Dim light grid are carved with by constant spacing, the protective layer is wraps closely about outer fiber, and the optical fiber is being carved with the portion of dim light grid
The outer stainless steel tube for being cased with C-shaped in position, the opening for the stainless steel tube that the optical fiber of hard-pressed bale matcoveredn passes through C-shaped are put into stainless steel tube
In, and connected between C-shaped stainless steel tube and protective layer by mechanical means.
Connected between the C-shaped stainless steel tube and protective layer by way of gluing or compress.
Compared with prior art, the beneficial effects of the utility model are：
1st, while fiber grating in protecting dim light grid array, ensured as first pipe protection layer using hard-pressed bale protective layer
Fiber grating synchronous with protective layer can perceive extraneous temperature, stress transmission.
2nd, stainless steel tube structure provides the support and protection of sufficient intensity for the fiber grating in dim light grid array；Make dim light
Grid array sensing optic cable avoids the influence to monitoring effect such as micro-bend, vibration in monitoring is applied.
3rd, it can be dim light grid to use stainless-steel pipe to carry out protecting support to the fiber grating position in dim light grid array
Fiber grating in array, which provides certain prestressing force, increases its susceptibility.
4th, fixed between C-shaped stainless steel tube and hard-pressed bale protective layer using mechanical connection manner, be further ensured that dim light grating array
Fiber grating and the ability of cable core structure collaborative perception in biographies sensing optical cable cable core.

Embodiment
With reference to specific embodiment, the utility model is expanded on further, it is new that these embodiments are merely to illustrate this practicality
Type rather than limitation the scope of the utility model.
A kind of cable configuration of the dim light grid array for sensor monitoring is the utility model is related to, including inscription there are dim light grid
The optical fiber 1 of array, protective layer 2 of the hard-pressed bale outside optical fiber 1, and it is enclosed on the stainless steel tube 3 of the C-shaped outside protective layer 2.
Dim light grid are carved with by constant spacing at multiple positions on the optical fiber 1, the protective layer 2 is wraps closely about optical fiber
Outside 1, the protective layer 2 is formed using organic material extrusion molding, the effect of protective layer 2 be ensure grating position to ambient temperature,
Strain variation can collaborative perception, and the protection and reinforcement of the first step are carried out to dim light grid array optical fiber, the optical fiber 1 carving
There is a stainless steel tube 3 that C-shaped is cased with outside the position of dim light grid, the stainless steel tube 3 that the optical fiber 1 of hard-pressed bale matcoveredn 2 passes through C-shaped is opened
It is put into, and is connected between C-shaped stainless steel tube 3 and protective layer 2 by mechanical means at mouthful, the mechanical means can be with
For gluing, compression etc., the C-shaped stainless steel tube 3 is used to optical fiber is carried out to strengthen support protection, and its effect is to ensure dim light grid array
In fiber grating will not be received in following stranding application process bending stress, vibration influence cause pitch change so that lead
Cause test result misalignment；And ensure that in process of production the fiber grating in dim light grid array can be applied appropriate tension force
Ensure its sensitiveness, C-shaped stainless steel can be caught in mode using rear enclosure and produce and process in addition, ensure support, fixing intensity
While, simplify production technology.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
