Abstract

The invention discloses a cable theft alarm system. The cable theft alarm system comprises a cable and an alarm circuit, wherein a plurality of main cable cores, ground wire cable cores and a conductive layer wrapping the main cable cores and the ground wire cable cores are arranged in the cable, the ground wire cable core at a load end of the cable is in short connection with the conductive layer, the ground wire cable core at a power source end of the cable is a first wiring point, and the conductive layer at the power source end of the cable is a second wiring point. The alarm circuit comprises a power source switch, an alarm, a control switch for controlling the work state of the alarm and a driver for driving the control switch to be on and off according to the on-off condition between the ground wire cable cores and the conductive layer after short connection, wherein one end of the power source switch is connected with a mains supply fire wire, the other end of the power source switch is connected with the first wiring point, the second wiring point is connected with the driver, the driver is connected with a mains supply null wire, the other end of the power source switch is connected with one end of the alarm, the other end of the alarm is connected with the control switch, and the other end of the control switch is connected with the mains supply null wire.

Description

[technical field] [0001] The invention relates to an alarm system for stolen cables. [Background technique] [0002] The special environment of the construction site requires that the cables used for construction machinery should have high tensile strength, high torsion resistance, oil resistance, acid and alkali resistance, wear resistance, impact resistance, and compression resistance. , Tensile resistance, oil resistance, acid and alkali resistance, its structure: the first type, both include insulated wire core and sheath layer, the insulated wire core is composed of inner conductor and outer insulation layer, the outer side of the insulation layer is the sheath layer, and the middle of the cable It is filled with core rubber or fiber; the second type is insulated wire core, fiber reinforced layer and inner and outer sheath layers. , The sheath layer is composed of inner and outer sheaths and a fiber reinforced layer between the inner and outer sheaths, and the middle o...
