Abstract:
PURPOSE: An intrusion detection device and an intrusion detection system including the same are provided to remove unnecessary detection information and to improve reliability. CONSTITUTION: A long distance communication unit(110) receives at least one detection information from a relay device(400). A short distance communication unit(120) receives noise information from a noise detection device located adjacent to an intrusion detection device. A display unit(130) outputs whether there is intrusion into the detection region. A control unit monitors possibility of intrusion into the detection region using the received detection information from the relay device and the noise information received from the noise detection device.

Abstract:
The present invention relates to a device and a method for arranging nodes in a three-dimensional space of a surveillance and reconnaissance sensor network system which forms two-tier topology in the three-dimensional space by considering a node installation height. For this, the device for arranging nodes in a three-dimensional space of a surveillance and reconnaissance sensor network system according to the present invention includes: multiple sensor nodes which are composed of a directional sensor and a non-directional sensor, detect an intruding target, and transmit a detected signal; multiple relay nodes transmitting the detected signal, which is transmitted from the sensor nodes, to a C2 terminal; and a node arranging device arranging the multiple sensor nodes and relay nodes in a three-dimensional space. The node arranging device calculates a detection distance for each sensor type based on a pre-calculated weighting value, which is applied to a detection distance, and on a node installation height for each sensor type; calculates a transmission distance for each sensor type based on a pre-calculated weighting value, which is applied to a transmission distance, and on the node installation height for each sensor type; arranges the multiple sensor nodes and relay nodes in a three-dimensional space based on the calculated detection distance and transmission distance; and constructs a two-tier topology network based on the arranged, multiple sensor nodes and relay nodes.
