Embodiment
Nuclear power station pipeline intrusion alarm device of the present utility model comprises fence, cable module, processing module 2 and alarm module 3.
Wherein, as shown in Figure 1, fence is arranged on the nuclear power station pipe outlet, is used to stop extraneous personnel and enters nuclear power station from pipe outlet.Fence has many railings and is secured together horizontal or perpendicularly, and as shown in Figure 1, railing comprises a perpendicular hurdle that horizontal bar is parallel with Duo Gen.Horizontal bar is hollow, and the cable module is passed horizontal bar and is fixed, and can't know from the outside then that inside is equipped with can realize the cable of reporting to the police.
As shown in Figure 3, the comparing unit 23 of this nuclear power station pipeline intrusion alarm device also comprises judgment means 231 and alarm output device 232, judgment means 231 is used for according to different comparative results, produce and differentiate the result, alarm output device 232 is used for sending different alarm according to described differentiation result.In judgment means 231, can preset a plurality of comparative results and differentiation result's contrast table, can produce different differentiation results with the difference of first electric signal according to second electric signal, thereby alarm output device 232 sends the alerting signal (as havoc or slight damage etc.) of different stage, certainly also can directly preset the grade of the rreturn value of second electric signal, according to the different alerting signal of the different generations of grade of the second electric signal rreturn value.
The difference of above-mentioned first electric signal, second electric signal can be that electricity is converted into parameter variation relevant under other forms, this form, for example in the 3rd preferred embodiment, as Fig. 4, Fig. 5, shown in Figure 6, described cable module comprises optical transmitting set 11, optical fiber 12 and optical receiver 13.Optical transmitting set 11 is used for described first electrical signal conversion to be light signal and described light signal is sent, and optical fiber 12 is used to transmit described light signal, and optical receiver 13 is used to receive described light signal, and described light signal is converted to second electric signal.The output unit 22 that receives second electric signal is integrated in the optical receiver 13.Then the difference of first, second electric signal can be represented with the energy loss of light signal in the optical cable transmission.
When under normal circumstances, optical fiber 12 places in the horizontal bar of fence intact and more straightly, the energy loss that light signal transmits in optical fiber 12 is seldom, the energy loss of predetermined threshold value is Δ P, the difference of the energy value of the light signal that normal loss is first, second electric signal representative is less than Δ P, processing unit relatively draws difference less than Δ P, and alarm unit does not send alarm; When fence was damaged by external force, optical fiber 12 was squeezed and vibration even flexural deformation, and energy loss increases to greater than Δ P, this moment comparing unit 23 signal that gives the alarm, alarm module 3 receives alarm signal and sends alarm.Simultaneously, predetermined threshold value also can be a refractive index, and the difference between the refractive index that processing unit amplifies and first, second electric signal of computing is represented separately finds that this difference when promptly exceeding predetermined threshold value, also will order about alarm unit and send alarm.
The foregoing description is to be used for detecting the cut situation of cable, and same embodiment also can be used to detect the situation of cable distortion, and embodiment can be arranged in the fence, no matter is to destroy invasion or damage deformation therefore, can detect by this device.In addition, the alarm of alarm unit can have various ways, for example sends out a warning, buzzing, LED flicker, rings alarm bell etc., and these ways of realization all are prior aries, and this paper repeats no more.
Adopt nuclear power station pipeline intrusion alarm device of the present utility model, under normal condition, second electric signal that output unit 22 receives and default first electric signal is identical, perhaps difference is less than predetermined threshold value, show that cable is normal, do not cause the variation of second electric signal; And be damaged or during crimp when cable; will cause that second electric signal that receives does not conform to first electric signal of presetting; there is difference between the two; when this moment, processing unit compared difference greater than predetermined threshold value; promptly send a signal and give alarm unit for alerting signal herein, alarm unit sends alarm, and people's prompting that receives the report for police service can go to the scene to check at once; stop the extraneous fence that destroys to invade nuclear power station, with the safety of protection nuclear power station from pipeline.
As preferred embodiment of the present utility model, described nuclear power station pipeline intrusion alarm device can comprise a plurality of processing modules 2, thereby the positioning unit in the alarm module 3 can be judged the concrete invasion position of convenient judgement, invasion position according to the source of alerting signal, saves the time that people find the invasion position.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
