METHOD AND SYSTEM FOR DETECTING A MOVING VEHICLE WITHIN A PREDETERMINED AREA |
摘要 |
<p>The system allows a reliable and automatic detection of moving vehicles and advantageously also identification of the moving vehicles. There is provided to install on a moving vehicle to be detected a WPAN node device (VN) (advantageously a ZigBee node device) and to install, e.g. on the ground, three WPAN node devices (N1, N2, N3) (advantageously three ZigBee node devices). One (N1) of the three WPAN node devices has a wide radio coverage area (A1) and acts as an "exciter" of the vehicle WPAN node device (VN), another one (N3) of the three WPAN node devices has a wide radio coverage area (A3) and acts as the "parent" of the vehicle WPAN node device (VN) and a further one (N2) of the three WPAN node devices has a narrow radio coverage area (A2) and acts as a "detector" of the vehicle WPAN node device. The three radio coverage areas (A1,A2) are sized and located so that a moving vehicle to be detected enters the area (A1) of the "exciter" before entering the area (A3) of the "parent" and before entering the area (A2) of the "detector". After detection the system provides for sending information to a fourth WPAN node devices present in a user mobile telephone terminal.</p> |
