Summary of the invention
the object of the invention is to propose a kind of power cable anti-theft detection method, it has overcome the deficiencies in the prior art, has realized and has had electricity and reliable detection and the early warning of power down mode to power cable.
for achieving the above object, the present invention proposes a kind of power cable anti-theft detection method based on optical fiber, its step is as follows:
(1) device is disposed: in the initiating terminal installation and measuring module of detected cable, with the parallel twin-core fiber (this optical fiber also can be directly and cable be combined into composite cable form) of installing of power cable, the signal transmitting and receiving port of detection module is connected with this two core fibre respectively, at the end of cable with optical fiber splicing device by two cold connections of optical fiber;
(2) demarcation of monitored cable: demarcate walking line position and monitoring position and the device id number of the detection module of this cable of monitored cable in monitoring main control server, and set up the management account of detection module and monitored cable;
(3) power supply mode is switched: detection module comprises alternating current detection sub-module, if alternating current detected, system automatically switches to AC-powered state, and can realize the charging to lithium battery; Otherwise be switched to lithium battery power supply state;
(4) terminal anti-theft detects: detection module regularly produces transmission information at random by certain coding rule, and send this information from transmitting terminal to optical fiber, if receiving end correctly can be received this information, represent that cable is normal, if the continuous Δ of receiving end is accepted for C time unsuccessfully, think that cable is cut, detection module is uploaded stolen information by GPRS to monitoring main control server simultaneously;
(5) anti-theft early-warning: monitoring main control server is receiving after the warning message that detection module sends over, to, in Surveillance center with electronic chart and sound and light signal form prompting warning message and occurrence positions and circuit, notify related personnel mobile phone with short message mode simultaneously.
the invention has the beneficial effects as follows there be power cable line stolen real-time reliable detection and the warning of realization to long distance under electricity and power-off condition, integrated electronics map and the stolen position of short message mode early warning and circuit, effectively improved disposal efficiency simultaneously.In addition, detection module only need be installed in power cable one end, and System Implementation is simple.
