Titel: (EN) Orientation method, device and system
(ZH) 一种定向方法、设备及系统
Zusammenfassung: front page image
(EN) Disclosed is an orientation method, comprising: determining a reference direction for orientation; when a first device rotates around an obstacle, receiving a wireless signal sent by a second device and acquiring a link quality parameter value according to the received wireless signal; determining the position having the greatest shadow fading of the first device according to the acquired link quality parameter value, and using the pointing direction of the first device at the position having the greatest shadow fading as a first pointing direction; and determining the orientation of the second device according to an included angle theta 1 between the reference direction and the first pointing direction and an included angle theta 2 between the reference direction and a second pointing direction, the second pointing direction being the pointing direction of the first device. Also disclosed are a first device and a system. By means of the present invention, the problem of low orientation precision and low searching efficiency for the second device can be solved.
(ZH) 本发明实施例公开了一种定向方法,包括:确定定向的基准方向;在第一设备绕着遮挡体转动时,接收第二设备发送的无线信号,获取根据接收到的无线信号链路质量参数值;根据获取的链路质量参数值判断所述第一设备的阴影衰落最重方位,并将所述第一设备在所述阴影衰落最重方位的指向作为第一指向;根据所述基准方向到所述第一指向的夹角θ1,以及所述基准方向到所述第二指向的夹角θ2确定所述第二设备所在的方向,所述第二指向为所述第一设备的指向。本发明实施例还公开了一种第一设备及系统。采用本发明,可解决定向精度差,对第二设备的搜寻效率低下的问题。
