Fusion positioning signal interference-free method and emission system

The invention discloses a fusion positioning signal interference-free method and a fusion positioning signal transmitting system, which enable the coverage range of other positioning signals to approach to an ultrasonic positioning signal. Other positioning signals assisting ultrasonic positioning approach to the coverage range of the ultrasonic positioning signals, the intersection area between the other adjacent positioning signals is reduced, it is guaranteed that the positioning equipment can select the optimal ultrasonic transmitting end for positioning interaction, and the positioning precision and the positioning effect are improved. 本发明公开了一种融合定位信号免干扰方法及发射系统，使其它定位信号覆盖范围向超声定位信号趋近。本发明通过使辅助超声定位的其它定位信号向超声定位信号的覆盖范围趋近，减小相邻其它定位信号之间的交集区域，保证定位设备能够选择最佳超声发射端进行定位交互，提高定位精度和定位效果。
