Anti-intruder security system with sensor network and actuator network
First Claim
1. An anti-intruder security system executing a predetermined reaction process on detection of intrusion into a facility to be guarded, the system comprising:
- member location detecting means for detecting the location of an authorized member who uses said facility;
intrusion location detecting means for detecting the location of intrusion into said facility;
actuators disposed at multiple locations in said facility, and executing said reaction process against said intrusion; and
invocation control means for invoking said reaction process by selecting said actuator for conducting said reaction process according to a relationship between the location of said authorized member detected by said member location detecting means, and the location of said intrusion detected by said intrusion location detecting means.

Abstract
The system in one embodiment operates while automatically switching among three processes including an absent-at-home guard process, an at-home guard process, and a non-guard process according to the positional relationship between the movable localizer and the internal guard surfaces/the external guard surface. When an actuator (such as a speaker and a white smoke generating unit) is integrated into the localizer, the localizer located at an intruder generates alarm sound or white smoke in the absent-at-home guard process. When the intruder moves inside the house, the localizer generating the alarm sound and the localizer generating the white smoke change following the intruder. The actuator is controlled such that an intruder is discouraged to approach the internal guard surface or such that a house member inside the internal guard surface can evacuate in a direction departing from the intruder in the at-home guard process.

7. An anti-intruder security system executing a predetermined reaction process on detection of intrusion into a facility to be guarded, the system comprising:
-
member location detecting means for detecting the location of an authorized member who uses said facility;
intrusion location detecting means for detecting the location of intrusion into said facility;
external guard surface memorizing means for memorizing an external guard surface for invoking an absent-at-home guard process when said authorized member is not present inside;

12. A localizer comprising:
-
an antenna unit;
a wireless transceiver unit connected with said antenna unit for transmitting/receiving information;
a distance measuring unit for transmitting/receiving a signal modulated by a specific code through said wireless transceiver unit so as to measure the distance to a device serving as a destination of the wireless transmission/reception;
a data communication unit for transmitting/receiving a signal modulated by a specific code through said wireless transceiver unit so as to conduct data communication with the device serving as a destination of the wireless transmission/reception;
an actuator for executing a reaction process against intrusion; and
a control unit responsible for overall control. - View Dependent Claims (13, 14, 20, 21)

15. A car security system comprising:
-
a control localizer installed inside a vehicle;
a fixed localizer installed on an internal surface of individual doors of said vehicle, and measuring the distance to another fixed localizer and to said control localizer;
a movable localizer held by a person who has authority of entering into/exiting from said vehicle; and
abnormality determining means for monitoring a change in the distance between said localizers installed inside said vehicle when said movable localizer exists outside an external guard surface set by the localizers installed inside the vehicle, and determining an existence of abnormality when the change in distance satisfies a predetermined condition, wherein a predetermined reaction process is executed when said abnormality determining means determines abnormality. - View Dependent Claims (16)

17. A sensor/actuator network system comprising:
-
a plurality of fixed nodes; and
a control node, wherein each of said fixed nodes comprises;
sensing means for sensing an ambient environment;
wireless communication means;
an actuator for applying action to the outside; and
control means for using said wireless communication means so as to transmit the information on said ambient environment detected by said sensing means to said control node, and simultaneously invoking said actuator in response to an instruction from the control node, said control node determines which of said fixed nodes should invoke said actuator based on said information on said ambient environment obtained from the fixed node, and then invokes the respective actuators of the determined fixed node to apply the action; and
wherein said control node monitors information on the distance between said fixed nodes as said ambient environment information. - View Dependent Claims (18)
