    • 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.
    • 该系统允许移动车辆的可靠和自动检测,并且有利地还可识别移动的车辆。 提供用于安装在移动的车辆上以便检测到WPAN节点设备(VN)(有利地是ZigBee节点设备)并且安装,例如, 在实地,三个WPAN节点设备(N1,N2,N3)(有利地是三个ZigBee节点设备)。 三个WPAN节点设备中的一个(N1)具有宽的无线电覆盖区域(A1),并且充当车辆WPAN节点设备(VN)的“激励器”,三个WPAN节点设备中的另一个(N3)具有宽 无线电覆盖区域(A3)并且充当车辆WPAN节点设备(VN)的“父”,并且三个WPAN节点设备中的另一个(N2)具有窄的无线电覆盖区域(A2)并且充当“检测器 “车辆WPAN节点设备。 三个无线电覆盖区域(A1,A2)的大小和位置被设置为使得待检测的移动车辆在进入“父母”的区域(A3)之前并且在进入区域之前进入“激励器”的区域(A1) (A2)。 在检测之后,系统提供向存在于用户移动电话终端中的第四WPAN节点设备发送信息。
