Within the scope of.
The present invention proposes a kind of cable anti-theft device.
Referring to Fig.1, in embodiments of the present invention, the cable anti-theft device, the cable anti-theft device include multiple having electricity
Anti-theft detection device 200 and without electric anti-theft detection device 300；It is described to have electric anti-theft detection device 200 according to predetermined interval distance
It is set to cable.It is worth noting that on a leader cable, can be provided with multiple has electric anti-theft detection device 200.There is electricity
Anti-theft detection device 200 is configured according to predetermined interval distance, such as can have electricity every 500 meters of settings one on cable
Anti-theft detection device 200.In the present embodiment, no electric anti-theft detection device 300 and Intelligent management terminal 100 may be contained within distribution box
In 600.
Intelligent management terminal 100 with it is described have electric anti-theft detection device 200 and it is described without electric anti-theft detection device 300 distinguish
Connection, it is described without electric anti-theft detection device 300 and it is described have electric anti-theft detection device 200 with cable connection.
It is described to have electric anti-theft detection device 200, for sending location information, the intelligence to the Intelligent management terminal 100
Energy management terminal 100 according to the positional information, judges whether cable is stolen.It should be noted that this has the antitheft detection of electricity to set
Standby 200 be that electricity is taken from cable, is worked normally for itself after being converted.Each there is the position of electric anti-theft detection device 200 to be
It is fixed, if cable is stolen, there is electric anti-theft detection device 200 to be stopped, Intelligent management terminal 100 does not receive position
Information, so that it may to judge that cable is stolen.
It is described without electric anti-theft detection device 300, for the impedance of cable after being powered off in detection cable, to the intelligent management
Terminal 100 sends impedance information, and the Intelligent management terminal 100 judges whether cable is stolen according to impedance information.Normal cable
Impedance in circuit is substantially stationary, after no electric anti-theft detection device 300 powers off in the cable, is carried out to the impedance in circuit
Detection, if finding, impedance changes, and judges that cable is stolen.
Therefore, there is electric anti-theft detection device 200 that there can be electricity in cable in the present invention, cable is carried out antitheft
Detection；And antitheft detection first can be carried out to cable without electric situation in cable without electric anti-theft detection device 300.Realized electricity,
Cable is comprehensively detected in the case of no electricity.

To street lamp power supply, road lamp power supply.For example, at night 7 points at 5 points in morning next day, open to the power supply of street lamp power supply, road lamp power supply.
Technical solution of the present invention is believed by there is electric anti-theft detection device 200 to send position to the Intelligent management terminal 100
Breath, the Intelligent management terminal 100 according to the positional information, judge whether cable is stolen.By described without the antitheft detection of electricity
The impedance of cable after being powered off in 300 detection cable of equipment, send impedance information, the intelligence to the Intelligent management terminal 100
Management terminal 100 judges whether cable is stolen according to impedance.In this way, realizing the round-the-clock detection to cable automatically, it is not necessarily to
Personnel make an inspection tour.Improve the reliability and efficiency of cable theft-prevention.
Further, the cable anti-theft device further includes warning device (not shown), the warning device and the intelligence
It can the connection of management terminal 100.The warning device is additionally operable to refer in the alarm for receiving the transmission of the Intelligent management terminal 100
When enabling, alarm is carried out.
The warning device can be connected with Intelligent management terminal 100 by way of the communications cable or wireless communication
It connects.When warning device can send out the warning message of the forms such as sound, light, electricity.It is found in time convenient on duty or tour personnel.
Specifically, for receiving the location information, obtain has according to the positional information the Intelligent management terminal 100
The actual number magnitude of electric anti-theft detection device 200 judges that cable is stolen when the actual number magnitude is less than present count magnitude.
The position of each Intelligent management terminal 100 is unique, and the location information sent out is also unique.Intelligent management terminal
100 by parsing location information and counted, and can be obtained the actual number magnitude of electric anti-theft detection device, then in present count
Magnitude is compared, you can is known whether stolen.For example, the present count magnitude of electric anti-theft detection device is 8, reality is detected
Quantitative value is judged as that cable is stolen when between 0~7.
Specifically, described without electric anti-theft detection device 300, the practical impedance of cable after being used in detection cable power off, to
The Intelligent management terminal 100 sends impedance information, the Intelligent management terminal 100 by the practical impedance and default impedance into
Row matching judges that cable is stolen if matching is unsuccessful.
For example, work as the cable of detection includes zero curve and the neutral conductor totally two cables, the alternating current of 220V is transmitted.It is anti-without electricity
Detection device 300 is stolen after this two cable power-off, the impedance of cable is detected.When an electricity in zero curve or the neutral conductor
After cable is stolen, it is parallel to load in circuit and reduces, thus the impedance detected without electric anti-theft detection device 300 increases, and detects
Practical impedance and default impedance mismatch then judge that cable is stolen.
