Abstract
Cable crash barrier apparatus precludes unwanted ingress and egress and electronically monitors breaches. Substantial thickness of the cable provides mechanical integrity resistant to, for example, a 400 lb. vehicle traveling at speeds up to at least about 52 miles per hour, while flexibility protects a central conducting member effective for forming a low-voltage circuit, the cable being supported by a plurality of anchoring members and not detracting from overall aesthetic of the area being circumnavigated.
Claims18
A method for preventing intrusion comprising the steps of:
- providing a crash-rated barrier system along at least a portion of a perimeter of a designated area with an outer cable housing an inner electrical circuit which is monitored by an electronic monitoring system;
- monitoring the circuit for interruptions in current;
- mapping the locus of any interruptions in current over the portion of the perimeter of the designated area;
- alerting a sensor receiver unit for transmitting data as to the mapped loci of interruptions;
- and
- repeating any of the preceding steps.
A method of limiting and detecting vehicular access, comprising:
- providing a crash barrier apparatus comprising a rope assembly suspended between bollards, wherein the rope assembly includes a flexible outer sheath and a conductive element positioned within the flexible outer sheath and further wherein the flexible outer sheath is configured to have a strength to restrain a traveling vehicle;
- passing current through a circuit including the conductive element;
- and
- monitoring the circuit for an interruption in the current.
