Embodiment Construction
[0058] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0059] Such as image 3 It is a schematic diagram of the system composition and working principle of an embodiment of the present invention, the system includes a beacon device, a target device to be positioned, a host device, a mobile device, a data collector and a position calculation device. Wherein, the host device (which can be a handheld personal computer, an embedded device or a processor on a mobile robot, which is used in this embodiment is a processor on a mobile robot) transmits the positioning command to the target to be positioned through the data output terminal The device data input end, the host device is installed at one end of the mobile device, and the target device to be positioned is installed at the other end of the mobile device. The target device to be positioned sends a radio frequency signal and an ultrasonic signal to the beac...
