As shown in Figure 1.

A kind of cable theft-prevention real-time positioning supervisory system, comprise Surveillance center's computer system 1, the webserver 2, the monitor terminal 3 of at least one, the output of monitor terminal 3 links to each other with Surveillance center computer system 1 by the webserver 2, the signal input part of described monitor terminal 3 links to each other with the output that resistance is measured loop 4, this resistance is measured loop 4 by the resistance of multiple parallel connection equal resistance R and connection lead 5,6 form, connect lead 5,6 are arranged in strip insulation base material 7, and resistance R is between the section and section of strip insulation base material 7.Resistance is wherein measured loop 4 can make hardware product shown in Figure 2, and lead 5,6 is wrapped in the insulating substrate 7, and resistance R also is wrapped in the insulation course.During concrete enforcement, can only measure loop 4 at the surface of cable parcel one deck resistance shown in Figure 2, also can only lay one deck resistance measurement loop 4 in the ground of cable certain altitude, preferably the two carries out simultaneously, all can report to the police under which kind of situation no matter can guarantee like this.

The monitor terminal 3 of present embodiment also is a computer system, and resistance is measured in the computer system of sending into again after loop 4 measured resistances can be handled by a conversion, amplification treatment circuit as monitor terminal and handled.

Fig. 3 is a principle of work synoptic diagram of the present utility model.

Resistance measurement of the present utility model loop 4 just is equivalent to the resistance 2 of dose known amounts and resistance and (establishes the resistance number=n that incorporates into, the resistance=R of resistance ₀), the circuit of the parallel resistance that constitutes according to known spacing (or geographic coordinate).If the resistance of each resistance 2 all equates=R ₀, the spacing between each resistance 2 represents that with L the resistance item nearest from the monitoring station is 1, is n from the item of supervising station resistance farthest, then:

Length overall=the L of protected cut cable ₁+ L ₂+ ... + L _N-1+ L _n

The monitoring all-in resistance R of this cut cable _T=R ₀/ n, R ₀=nR _T

Suppose; the unprincipled fellow is arranged; when certain of protected cut cable is stolen on a bit; it must break ground and destroy the resistance that is positioned at cable top earlier and measure loop 4; lead 5 and/or 6 will be cut off; if stealer fails to cut off the lead 5,6 that is positioned at cable top by sheer good luck, it must be cut off being wrapped in the lead 5 and/or 6 that cable draws when shearing cable so, thus cause the section of monitoring changes in resistance.Be between the resistance that item is x and x+1 if steal point, then the all-in resistance measured of supervising device has not been No. 1 all-in resistance to the n parallel connection, but arrives x parallel resistor value No. 1, that is:

Monitored resistance R _x=R ₀/ x=nR _T/ x then,
