Abstract
The invention discloses a self-adaptive cable antitheft device. A tail end module is added to the tail end of a power supply line, an alternating current is a high resistance state, and a direct current is a low resistance state; a direct current signal generation and collection device is installed on the front end of the power supply line; if a cable is detected to be in a power off state, then whether the cable is stolen according to whether the working current of the cable changes suddenly; if the cable is detected to be in a non working voltage state, a direct current signal is generated and sent to the tested cable, the electric signal is relayed by the tail end module of the cable and is fed back to the direct current signal generation and collection device, and when the fed-back signal is interrupted, then the cable is judged to be stolen. The invention further discloses a self-adaptive cable antitheft method. According to the invention, the direct current signal generation and collection device is installed on the front end of the power supply line, so that whether the cable is stolen can be still judged when the cable is power off.
Description
Technical field
The present invention relates to a kind of service cable anti-theft technique, especially a kind of self-adaptation cable anti-theft device and method.
Background technology
Existing cable anti-theft technique detects in supply line whether have electric current, and whether Lai Pan supply line breaks, thus judges that whether cable is stolen.This just requires that circuit must have electricity, illuminating line when street lamp is turned off the light, supply line when not being energized, just cannot to report to the police during line maintenance, and cable stolen time exactly be mostly that circuit does not have the electric time.
The acceleration of Urbanization Construction, city size is increasing, and the road lighting cable of the combination area of city and country, telecommunication cable, service cable are often stolen, and this brings many troubles to city manager, and economic loss is huge.
Summary of the invention
No matter supply line has electricity there still be not electricity to the invention provides one, can judge the self-adaptation cable anti-theft device whether cable is stolen and method.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of self-adaptation cable anti-theft device, add a terminus module at the end of supply line, interchange is high-impedance state, and direct current is low resistive state; Fill a direct current signal to produce and harvester in the front end of supply line; If detect, cable is in electriferous state, then according to cable working current whether undergo mutation judge whether stolen; If detect, cable is without operating voltage state, then produce a direct current signal and be sent to tested cable, this electric signal carries out relaying by cable end piece module, and feeds back to direct current signal generation and harvester, when feedback signal is interrupted, be then judged as that cable is stolen.
A kind of self-adaptation cable theft-prevention method, comprises the steps:
Step one, add a terminus module at the end of supply line, interchange is high-impedance state, and direct current is low resistive state; Fill a direct current signal to produce and harvester in the front end of supply line;
Whether step 2, detection streamer are in electriferous state, if detect, cable is in electriferous state, then according to cable working current whether undergo mutation judge whether stolen; If detect, cable is without operating voltage state, then produce a direct current signal and be sent to tested cable, this electric signal carries out relaying by cable end piece module, and feeds back to direct current signal generation and harvester, when feedback signal is interrupted, be judged as that cable is stolen.
Wherein, whether undergo mutation according to cable working current and judge whether that stolen concrete mode is: collection analysis is carried out to the voltage of cable, current signal, if cable working current is undergone mutation, in process chip, by application program, the electric quantity data of collection is carried out Logic judgment by computation model, if analyzing conclusion is that cable is stolen, an alerting signal will be produced for this cable, be sent to mainboard by the further identifying processing of mainboard.
The invention has the beneficial effects as follows: the present invention produces and harvester by filling a direct current signal in the front end of supply line, makes cable in uncharged situation, still can judge that whether cable is stolen.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention cable is without circuit diagram during operating voltage state.
Embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
In the present embodiment, as shown in Figure 1, the embodiment of the present invention is a kind of self-adaptation cable anti-theft device, and add a terminus module at the end of supply line, interchange is high-impedance state, and direct current is low resistive state; Fill a direct current signal to produce and harvester in the front end of supply line; If detect, cable is in electriferous state, then according to cable working current whether undergo mutation judge whether stolen; If detect, cable is without operating voltage state, then produce a direct current signal and be sent to tested cable, this electric signal carries out relaying by cable end piece module, and feeds back to direct current signal generation and harvester, when feedback signal is interrupted, be then judged as that cable is stolen.Particularly, when cable is without operating voltage state, circuit comprises input circuit, buffer circuit, voltage detecting, impedance transformation and anti-theft signal and feeds back this few major part.
The present embodiment self-adaptation cable theft-prevention method comprises the steps:
Step one, add a terminus module at the end of supply line, interchange is high-impedance state, and direct current is low resistive state; Fill a direct current signal to produce and harvester in the front end of supply line;
Whether step 2, detection streamer are in electriferous state, if detect, cable is in electriferous state, then according to cable working current whether undergo mutation judge whether stolen; If detect, cable is without operating voltage state, then produce a direct current signal and be sent to tested cable, this electric signal carries out relaying by cable end piece module, and feeds back to direct current signal generation and harvester, when feedback signal is interrupted, be judged as that cable is stolen.Use direct current signal, effectively can shield the interference that tested cable produces under complex electromagnetic environment, thus ensure the accurate and effective of alerting signal.
Wherein, whether undergo mutation according to cable working current and judge whether that stolen concrete mode is: collection analysis is carried out to the voltage of cable, current signal, if cable working current is undergone mutation, in process chip, by application program, the electric quantity data of collection is carried out Logic judgment by computation model, if analyzing conclusion is that cable is stolen, an alerting signal will be produced for this cable, be sent to mainboard by the further identifying processing of mainboard.
When tested cable operating voltage generation break-make, process chip by gathering electricity data analysis identification, and at mutation process, automatically prolongs the judgement time, is erroneous judgement to eliminate due to electrical parameter sudden change band.
When circuit only uses part sense channel, by Parameter analysis before and after tested cable energising, can automatically identify and whether have external cable, when not connecing detection streamer, automatic shield is reported to the police to the cable of this passage.
The embodiment of the present invention produces and harvester by filling a direct current signal in the front end of supply line, makes cable in uncharged situation, still can judge that whether cable is stolen.
