Abstract

The invention provides an active cable anti-theft device and system. The active cable anti-theft device comprises a sleeve, wherein at least two inner convex rings are arranged in the sleeve, and the sleeve is used for a cable to penetrate through; an active alarm device, which is fixedly connected to the cable and is arranged between the two inner convex rings of the sleeve, wherein the active alarm device comprises a conductive claw, so that under the condition that the cable is dragged, the conductive claw is contacted with any one of the two inner convex rings to switch on a built-in alarm circuit of the active alarm device and send a remote alarm signal. An active alarm device is additionally arranged and fixedly connected to an insulating sheath of a cable, an alarm circuit is arranged in the active alarm device, a conductive claw is arranged, when the conductive claw makes contact with a first inner convex ring, the conductive claw is pressed towards the circle center in the circumferential direction to be connected with the alarm circuit, and when the conductive claw makes contact with a second inner convex ring, the conductive claw is pressed in the axial direction to be connected with the alarm circuit. Therefore, anti-theft alarm can be realized in two directions.

Description

technical field

[0001] The technology belongs to the field of cable anti-theft alarm technology, and mainly relates to an active cable anti-theft device and system. Background technique

[0002] With the rapid development of municipal construction, the laying range of street lamps is constantly expanding. Because the transmission cables of street lamps contain precious metals, they are of high value and thefts occur frequently.

[0003] The existing street lamp power transmission cable lacks an active alarm device when theft occurs, so that the stolen cable cannot be discovered in time, but can only be discovered after the street lamp is not lit after the theft. First, the loss is large, second, the lighting is affected, and third It is difficult to detect the theft case, and so on. Contents of the invention

[0004] The object of the present invention is to provide a cable anti-theft device and system that actively alarms when a cable is stolen.

[0005] The invention p...
