In a first working condition, in specific use, the magnetic field emission sensor array can be arranged on the periphery of the target area so that the sensors forming the array emit magnetic energy along a straight direction, and the receiving sensor arrays are arranged on the opposite sides of the magnetic field emission sensor array, and each leakage sensor structure in the receiving sensor arrays is unchanged and is used for receiving the magnetic energy emitted by the emission sensors; the received path senses the emitted magnetic energy through the grating on the outermost packaging sleeve, the slotted hole on the secondary outer protective sleeve and the grating on the cable core, and then analyzes the magnetic energy received by the electromagnetic core, so as to judge whether personnel intrude.
