Abstract
An intrusion detection system and method utilizing a power transmission cable connected to a source of radio frequency signals. A data transmission cable is associated with the power transmission cable and is provided with a plurality of radio frequency identification chips. The power transmission cable would induce an electromagnetic field within the data transmission cable allowing each of the RFID chips to transmit a signal during normal operation. However, if an intrusion occurs or the power transmission cable or data transmission cable is severed, the system according to the present invention, would be able to determine the exact point of intrusion based upon the signals received or not received from the RFID chips.
Claims28
A device for sensing the occurrence of an event, comprising:
- a power transmission cable;
- a data cable spaced apart from said power cable;
- a plurality of identification chips spaced apart from each other along said data cable;
- a source of radio frequency signals connected to said power transmission cable creating an electromagnetic field inducing a current in said plurality of identification chips, thereby allowing a signal to be broadcast from each of said identification chips along said data cable;
- and
- a system controller in communication with said data cable for receiving signals broadcast from said identification chips, wherein the lack of receipt of a signal from one or more of said identification chips is indicative of the occurrence of the event.
A method of detecting the occurrence of an event, including the steps of:
- installing a power transmission cable;
- installing a data cable spaced from said power transmission cable, said data cable provided with a plurality of identification chips spaced apart from one another;
- transmitting a radio frequency signal along said power transmission cable, thereby creating an electromagnetic field and inducing a current in each of said identification chips, allowing each of said identification chips to broadcast a signal along said data cable, when a current is induced in each of said identification chips;
- receiving each of said signals produced by said identification chips in a system controller connected to said data cable;
- and
- determining the occurrence of an event based upon the signals received by said system controller.
A device for sensing an intrusion onto a piece of property having a plurality of vertical poles provided along at least a portion of the property, comprising:
- a data cable attached to the vertical poles at an elevated distance above the ground;
- a plurality of identification chips spaced apart from each other along said data cable;
- a power transmission cable spaced from said data cable;
- a source of radio frequency signals connected to said power transmission cable creating an electromagnetic field inducing a current in said plurality of identification chips, thereby allowing a signal to be broadcast from each of said identification chips along said data cable;
- and
- a system controller in connection with said data cable for receiving signals broadcast from said identification chips, wherein the lack of receipt of a signal from one or more of said identification chips is indicative of the presence of an intruder on the piece of property.
