ABSTRACT:
It is provided an alarm system for underground boundary intrusion detection, and methods for deployment and operation. The deployment method includes constructing of a computing-and-empowering apparatus, connecting thereof a longitudinally extended power-and-communication cable, connecting addressable junction-units, storing a physical location and an address of each junction-unit in the computing-and-empowering apparatus, connecting each addressable junction-unit to a wired-mole having a wire bundle which initially is contracted there within and measurable physical characteristics, and infiltrating the wired-moles normally into ground to a desired depth. In operation, the sensors frequently measure the physical characteristics of the wired-mole, deliver the measurement of the physical characteristics to the computing-and-empowering apparatus, which stores and analyzes the measurements, comparing past and present measurements. Once it concludes that an underground boundary intrusion might occur, it issues an alarm signal which includes the physical location of the addressable junction units where intrusion presumably has occurred.
