Abstract
The utility model provides a detecting device capable of detecting a vibration intrusion signal, consisting of a vibration cable sensor and a data collector which are connected together. When an applied force is acted on certain point on the vibration cable to generate the vibration, a changeable current is generated inside a bare copper wire conductor inside the cable, a changeable voltage is formed on the interface of the data collector, and the data collector filters and amplifies the signal; if the signal accords with the warning condition, the switching value signal is outputted.
Description
Technical field
The utility model relates to sniffer, refers in particular to a kind of sniffer that can detect vibration.
Technical background
At present, the warning device of anti-invasion generally uses infrared ray as alarm detector on the market, and whether the type detector has object to block infrared signal to judge whether that the someone enters the protection zone by surveying the external world.But if other objects are arranged, and blocked infrared ray as fallen leaves, flying bird, the swing of wind trees or bigger rain, greasy weather gas, then can cause system's false alarm or inefficacy.And, commonly used as passive infrared detector on perimeter alarm, can only survey linear zone of protection, can not be applied to irregular zone of protection.Above situation is the ubiquitous problem of sniffer that current anti-intrusion alarm equipment adopts.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing anti-intrusion alarm sniffer, the utility model provides a kind of vibration wireline of utilizing as sensor, convert vibration signal to electric signal, and this signal is handled, judged the sniffer of warning, output switching value signal.
The technical scheme that its technical matters that solves the utility model adopts is: an end of vibration wireline is connected with the interface circuit of data acquisition unit, with two bare copper wire conductors of the vibration wireline other end and two RVV conductors respectively short circuits form two independently loops.Vibration wireline is made of two bare copper wire conductors, two RVV conductors and two rubber magnetic stripes, outer layer polyethylene sheaths, wherein the signal wire by two band sheaths is arranged in parallel, the both sides bare copper wire that respectively is arranged in parallel, 4 conductors are parallel and be closely arranged on the same plane, upper and lower on the plane that these 4 conductors are formed is respectively placed a rubber magnetic stripe, with insulation film all material is wrapped, outer around last metal screen layer, outermost layer is packaged into cable with polythene material, has so just constituted vibration wireline.When external force acts on that certain is some on the vibration wireline, two bare copper wire conductors in the cable are made cutting magnetic line movement in two formed magnetic fields of rubber magnetic stripe, according to electromagnetic coupling theory, in this conductor, can produce electric current, because an end short circuit of these two conductors, so between two bare copper wire conductors of the other end of cable, just produced the voltage signal that changes.Data acquisition unit is gathered the voltage signal of this variation, signal is carried out filtering, filtering interference signals and noise, filtered signal is amplified, be amplified to the discernible scope of decision circuitry, the signal evaluation circuit that is made of single-chip microcomputer and peripheral circuit is analyzed comparison to attributes such as the amplitude of this signal, pulse number, pulse width, cohorts, judges whether signal meets alert if, if meet then send a switching value signal toward the switching value output interface circuit.One end short circuit of two RVV in the vibration wireline, the other end inserts the interface circuit of collector, under the normal condition, can measure two RVV from the collector interface is short circuit, if invasion personnel cut off vibration wireline, can measure two RVV for opening circuit from the collector interface, collector can determine whether to send the switching value signal of break alarm by judging the break-make situation between two RVV.Metal screen layer maskable outside electromagnetic interference in the vibration wireline reduces the influence of external electromagnetic field to system to greatest extent.
The utility model adopts Vibration-sensing cable as vibration detector, acid and alkali-resistance, anti-unaccelerated aging, long service life, Vibration-sensing cable can be layed in zone of protection irregular, different terrain.Data acquisition unit can be analyzed, compare, judge the various characteristics of continually varying electric signal, can reduce the wrong report that a variety of causes causes effectively, has improved the reliability of sniffer.

Embodiment
In Fig. 1,4 conductors of one end of vibration wireline (1) and the interface circuit of data acquisition unit (2) connect one to one, the other end of vibration wireline (1) is with two bare copper wire conductors (3), two RVV conductors (4) are short circuit respectively, when external force acts on vibration wireline (1) when going up certain and a bit causing vibration, the induced current that changes on the bare copper wire conductor (3), the short circuit loop of the end by vibration wireline (1), two bare copper wire conductors (3) at vibration wireline (1) other end are gone up the induced voltage that forms variation, this voltage enters data acquisition unit (2) by interface circuit (5), data acquisition unit (2) carries out filtering to voltage signal, amplify, relatively, judge, to meeting the signal of alert if, externally send a switching value signal by the switching value output circuit.
In Fig. 2, the parallel placement of two RVV conductors (10), the parallel respectively both sides that are placed on two RVV conductors (10) of two bare copper wire conductors (11), four conductors are parallel and on same plane, upper and lower on the plane that these four conductors are formed is respectively placed a semi-circular magnetic stripe (9), the flat one side of semi-circular magnetic stripe (9) is close to four conductors, to arrange closely orderly two RVV conductors (10) with insulation film (8), two bare copper wire conductors (11) and two semi-circular magnetic stripes (9) are wrapped, to guarantee that inner structure can not change because of vibration, skin at insulation film (8) superscribes metal screen layer (7), with the interference of shielding external electromagnetic field, superscribe cable cover(ing) at the outermost of metal screen layer (7).
In Fig. 3, the electric signal that signal input interface circuit in the data acquisition unit receives enters filter amplification circuit, but filter amplification circuit filtering high-frequency interferencing signal, and the invasion signal band feature selecting passband that can arrive according to on-the-spot test, remain with the signal of usefulness, because the amplitude of this electric signal is smaller, maximal value is 0.1v, will analyze this signal, compare, must signal be amplified to maximal value by amplifying circuit is 5v.Signal after the single-chip microcomputer judgement of being made up of single-chip microcomputer and peripheral circuit, identification, control circuit amplify filtering carries out analog to digital conversion, and the characteristics such as amplitude, pulse number, pulse width, cohort of the signal after the conversion are analyzed, relatively, to meeting the signal of alert if, relay in the Single-chip Controlling switching value output circuit produces a switching value.To not meeting the situation of alert if, then do not produce the switching value signal.
