Title: Motion detectore for electronic fence

Description:
FIELD OF THE INVENTION 
     The present invention relates to motion detector for electronic fence. 
     The type of the fence is a wire strings fence that stretched horizontally between two poles and in the middle of those poles there is a detectors pole which contains the motion detectors, those detectors are attach to the wire strings and have the ability to detect motion on those strings and to give a report on it. 
     This report is send to the fence control system that analyzes and presents them to the user. 
     BACKGROUND OF THE INVENTION 
     Other objects and advantages of the invention will become apparent as the description proceeds. 
     Usually electronic fence need to be very sensitive to movement on the wire strings to detect an act of penetration to the safe area. 
     The fence detector that attaches to the string wire need to be very reliable to detect a breach on the fence with minimum of detector failures that reflects with false alarms or threats not detected. 
     The object of the present invention is a new type of movement detector which detects motion on it&#39;s attaches string wire and sends a report to the control center. 
     The new detector uses the technology of acceleration sensor to sense when motion occurs on its attaches fence string wire. 
     When a motion occurs on the string wire it causes the motion detector to move, the acceleration sensor sense those movements and notify them to the control center, with this data the system can know when a breach has made on the fence. 
     SUMMARY OF THE INVENTION 
     The present invention relates to motion detector for electronic fence that uses the acceleration sensor technology. 
     The acceleration sensor can sense when it moves and then sends it&#39;s new moving coordination (x y z) to the fence control system. 
     According to the present invention the motion detector detects motion by an acceleration sensor that placed inside of it, the detector installs on moving system inside the detectors pole which enable it to move when a motion occurs on it&#39;s attaches string wire. 
     When the detector is moving the acceleration sensor sends its moving data to the fence control system which uses it to detect what kind of breach has made on the fence.
