Description of drawings
Fig. 1 is the structural representation of the online antitheft anti-outside destroy detection alarm device of sheathed cable.
Embodiment
As shown in Figure 1, the online antitheft anti-outside destroy detection alarm device of a kind of sheathed cable comprises signal generator 110, the signal coupler 120 that loads described detection signal that detection signal is provided, the signal transducer 140 that picks up described detection signal, for detection of the monitoring device 150 of described detection signal and the insulated conductor 130 that is used for transmitting described detection signal; Described signal coupler 120 is connected with described signal generator 110, and described signal transducer is connected with 140 described monitoring devices 150, and described insulated conductor 130 passes the center pit of described signal coupler 120 and the center pit of described signal transducer 140 successively.
The online antitheft anti-outside destroy detection alarm device of above-mentioned sheathed cable, in the process of work, signal generator 110 sends detection signal, signal coupler 120 receives described detection signal, and described detection signal loaded on the closed-loop path that armor 210 and screen layer 220 consist of by ground connection by described insulated conductor 130, signal transducer 140 picks up described detection signal, the detection signal that monitoring device 150 will pick up gathers and carries out analyzing and processing, judges according to the amplitude of variation of described detection signal whether described closed-loop path is destroyed.Must destroy first armor 210 because destroy sheathed cable; if armor 210 is destroyed; then described closed-loop path is cut off; the main channel that is detection signal is destroyed; the detection signal that described signal transducer 140 picks up can diminish suddenly; described monitoring device 150 detected change in detection signal amplitudes are very large; judge that then the closed-loop path that armor 210 and screen layer 220 consist of is destroyed; thereby described monitoring device 150 notifies warning message to the personnel of receiving a crime report, in order in time sheathed cable is protected.Described insulated conductor 130 passes the center pit of described signal coupler 120 and the center pit of described signal transducer 140 successively, so that described warning device does not form current return with sheathed cable, thereby do not change grounding characteristics and the electric property of armor 210 and screen layer 220, stability and the security of warning device have been improved, good anti-theft effect.
Should be understood that described insulated conductor 130 is connected with the armor 210 of sheathed cable, perhaps an end of described insulated conductor 130 is connected with the armor 210 of sheathed cable, and the other end is connected with earth point.Such structure realizing signal coupler 120 with the detection signal that receives, loads on purpose in the closed-loop path that armor 210 and screen layer 220 consist of by ground connection by described insulated conductor 130.
In present embodiment, described monitoring device 150 is disposed with acquisition module 152, signal processing module 154 and signal output module 156.Acquisition module 152 is sampled the detection signal that described signal transducer 140 picks up; signal processing module 154 carries out data with the detection signal that gathers to be processed; if the detection signal that gathers is undergone mutation; it is destroyed with the closed-loop path that screen layer 220 consists of then to analyze judgement armor 210; thereby signal processing module 154 sends instruction; signal output module 156 is notified warning message to the personnel of receiving a crime report, in order in time sheathed cable is protected, good anti-theft effect.
In present embodiment, described acquisition module 152 is disposed with sample circuit module 1520, amplifying circuit module 1522 and bandpass filtering rectification circuit module 1524.Described signal transducer 140 picks up detection signal, 1520 pairs of detection signals that pick up of described sample circuit module are sampled, 1522 pairs of detection signals of described amplifying circuit module carry out preposition amplification, detection signal is carried out the filtering processing with narrow band filter in the last bandpass filtering rectification circuit module 1524 and full-wave rectifying circuit carries out the rectification processing to detection signal, can identify the also detection signal of analyzing and processing so that described detection signal is signal processing module 154.
In present embodiment, described signal processing module 154 is provided with embedded computer, described embedded computer will be sampled and the data processing through the detection signal that acquisition module 152 is processed, system is the generating period signal amplitude automatically, if significantly sudden change occurs in the cyclical signal amplitude, judge that then sheathed cable is destroyed, anti-theft effect is accurate.
In present embodiment, described signal output module 156 is disposed with photoelectric isolating circuit module 1561 and communicator 1560.When if sheathed cable suffers outside destroy; significantly sudden change occurs in the cyclical signal amplitude in the described embedded computer; described embedded computer sends to communicator 1560 with warning message by photoelectric isolating circuit module 1561; communicator 1560 sends to the personnel of receiving a crime report with warning message, in order in time sheathed cable is protected.
In a preferred embodiment, described communicator 1560 comprises SMS module 1562 and communication module 1564.When sheathed cable during by outside destroy, SMS module 1562 directly sends to warning message on the personnel's mobile phone of receiving a crime report, communication module 1564 reports the monitoring machine station with warning message, when if the personnel of receiving a crime report are leaked the receiving alarming information, the staff at monitoring machine station also can in time process warning message, can in time convey to the relevant staff to guarantee warning message.
In other embodiments, described warning device also is provided with power module 160, and described power module 160 can be respectively signal generator 110, acquisition module 152, signal processing module 154 and signal output module 156 the independently power module of insulating power supply is provided.By such power supply mode; provide independent insulation blocking to each module in the warning device; in the time of can preventing that thunder and lightning reverse impact or other emergency situations from disturbing warning device, all modules in the warning device all are affected, and have strengthened the reliability of equipment.When warning device breaks down, by every circuit is investigated, can find out more fast the trouble spot simultaneously, convenient maintenance.Even it is pointed out that power module 160 is not set, namely extraneous power-supply unit is powered or other power supply modes by warning device is accessed, and also can realize sheathed cable is carried out the purpose of online antitheft anti-outside destroy monitoring.
In a preferred embodiment, the frequency of described detection signal is 800 ~ 1200 hertz.Because if be carried in the described closed-loop path detection signal too a little less than, when the closed-loop path was cut off, change in detection signal was not obvious, might cause monitoring device 150 errors in judgement.If the detection signal that is carried in the described closed-loop path is too strong, the radiation that produces produces other signals of periphery unavoidably and disturbs, affect resident's quality of life, so the frequency of described detection signal can rationally be set to 800 ~ 1200 hertz, the effect the when frequency of wherein said detection signal is 1000 hertz is best.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
