Patent ID: 8004405

Claim:
A method for deploying an alarm system characterized by being fitted for deploying an alarm system for underground boundary intrusion detection, the method comprising: a) constructing a computing-and-empowering apparatus; b) connecting thereof at least one longitudinally extended power-and-communication cable; c) connecting to the power-and-communication cable a first number of addressable junction-units, whereas each addressable junction unit comprises a communication-controller and a sensor; d) storing a physical location and an address of each junction-unit in said computing-and-empowering apparatus; e) connecting each addressable junction-unit to one of a first number of wired-moles, said wired-mole includes a wire bundle which initially is contracted there within, whereas the wired mole has at least one physical characteristic measurable by said sensor of the junction unit connected thereof; f) infiltrating the wired-moles into ground in a certain direction which is substantially parallel for the majority of the wired-moles; g) directing said computing-and-empowering apparatus to command the wired moles to each start digging operation and accordingly release its wire bundle, and to continue said digging operation until a predetermined wire bundle length has been released by the wired-mole; and h) once the majority of the wired-moles have stopped digging upon release of the corresponding predetermined wire bundle length, declaring an operational mode of an alarm system, said alarm system comprised of said computing-and-empowering apparatus, said at least one longitudinally extended power-and-communication cable, said first number of addressable junction units, and at least the majority of said first number of wired-moles; whereby in said operational mode each of said sensors frequently measures said at least one physical characteristic of a corresponding one of said wired-moles connected thereof, and delivers the measurement of the physical characteristics to said computing-and-empowering apparatus, which stores and analyzes the measurements, comparing past and present measurements, and once said computing-and-empowering apparatus concludes that an underground boundary intrusion might be occurring, it issues an alarm signal comprised of the physical location of the addressable junction units where intrusion presumably occurred.
