As an improvement of the above technical solution, pressure spring, the pressure are provided between the limiting component and cross bar lower surface
Circlip is wound on the outside of planar protective net.
As an improvement of the above technical solution, a side edge is provided with arc sheet rubber, the arc rubber on the cross bar
Film is gradually bonded to stress sensing optical fiber after being pressurized and moves.
As an improvement of the above technical solution, the side on the arc sheet rubber far from cavity is evenly distributed with protrusion
Portion.
In above-mentioned technical proposal anti-theft alarm system main structure with for vertical bar, cross bar and planar protective net composition every
From structure, the cavity inside of cross bar is arranged in stress sensing optical fiber, and stress sensing outer fiber is provided with the limit of engaging
Component is destroyed in planar protective net, squeezes, climbs, rocks etc. since limiting component is fixedly connected with planar protective net
When invading movement, then leading to stress sensing optical fiber indirectly, deformation occurs and generates stress signal, after controller detects signal
Alarm is generated, realizes the function of circumference security protection, there is beneficial technical effect and significant practical value.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the anti-theft alarm system based on circumference security protection of the present invention；
Fig. 2 is the position view of cross bar and its internal cavities in the present invention；
Fig. 3 is the partial enlarged view of Fig. 2 hollow cavity position.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention provides a kind of anti-theft alarm system based on circumference security protection, including it is vertical
Bar 10 is provided with cross bar 20 at the top of vertical bar 10, planar protective net 30 is provided between vertical bar 10 and cross bar 20；In cross bar 20
With cavity 21, stress sensing optical fiber 40 is provided in cavity 21,20 lower surface of cross bar offers the through-hole 23 for being directed toward cavity 21,
Be provided in cavity 21 engaging stress sensing optical fiber 40 limiting component 22,30 edge of planar protective net pass through through-hole 23 after with sky
Limiting component 22 in chamber 21 is fixedly connected.In the technical solution anti-theft alarm system main structure be vertical bar 10, cross bar
20 and planar protective net 30 form isolation structure, stress sensing optical fiber 40 is arranged in inside the cavity 21 of cross bar 20, and answers
The limiting component 22 of engaging is provided on the outside of power sensor fibre 40, since limiting component 22 is fixedly connected with planar protective net 30,
When planar protective net 30 such as is destroyed, squeezes, climbs, rocks at the invasions movement, then it can lead to stress sensing optical fiber 40 indirectly
Deformation occurs and generates stress signal, and alarm is generated after controller detects signal, realizes the function of circumference security protection.
In above scheme, stress sensing optical fiber 40 could alternatively be other touch sensors, such as pressure sensor, answer
Become sensor or contact type temperature sensor, effect is identical as the effect of stress sensing optical fiber 40, can be in indirect external force
Under effect, corresponding reaction signal is generated.
Further, limiting component 22 has arc-shaped slot 221, the arc-shaped slot 221 and stress sensing light in the present invention
The rounded outer surface of fibre 40 is adapted, and the effect of limiting component 22 at this time is divided into two aspects: on the one hand, limiting component 22 passes through arc
Shape card slot 221 is engaged on 40 side of stress sensing optical fiber；On the other hand, limiting component 22 is to the stress being set in cross bar 20
Sensor fibre 40 is effectively supported, and the service life of stress sensing optical fiber 40 is improved.
On the basis of above scheme, limiting component 22 and cross bar are provided with pressure spring 24 between 20 lower surface, the pressure spring 24
It is looped around the outside of planar protective net 30, wherein the effect of pressure spring 24 is to be destroyed in planar protective net 30, squeezed, climbed, shaken
After the invasions such as rolling movement, the fast quick-recovery of resilience of pressure spring 24 can be utilized, avoid stress sensing optical fiber 40 always in deformation
State.
Further, on cross bar 20 a side along being provided with arc sheet rubber 50, arc sheet rubber 50 be pressurized after gradually to
The fitting movement of stress sensing optical fiber 40, there are three the effects of the arc sheet rubber 50: first, cross bar 20 is after laying, cavity 21
When interior other component needs to install or replace, by disassembling the arc sheet rubber 50 on cross bar 20, phase can be carried out
Answer the installation and replacement of component；Second, cross bar 20 is located at the top of planar protective net 30, when have invader climbing to cross bar 20
When setting or abutting on cross bar 20 using staircase, then planar protective net 30 may be directed across, therefore arc sheet rubber 50
Design, can at such, deformation occurs, to cause stress sensing optical fiber when fitting on stress sensing optical fiber 40
40 deformation simultaneously generate stress signal；Third usually has birds and stops since cross bar 20 is located at the top of planar protective net 30
It leans on, it is thus possible to wrong report can be generated, therefore protrusion can be evenly distributed in the side of separate cavity 21 on arc sheet rubber 50
Portion 51 generates stimulation to the foot palm part of the birds of stop by lug boss 51, drives birds stop.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
It should not be considered as limiting the scope of the invention, all changes and improvements made in accordance with the scope of the present invention should all
It still belongs within covering scope of the present invention.
