Abstract

The invention relates to an indoor positioning and trajectory tracking device, system and method. The device comprises an posture tracking component, a speed tracking component, a main controller, a communication circuit, a signal shielding device and a switching power supply. The posture tracking component, the speed tracking component and the signal shielding device are each electrically connected with the input end of the main controller, the output end of the main control component is electrically connected with the input end of the communication circuit, and the output end of the communication circuit is electrically connected with the external receiving terminal. The device of the invention acquires the posture information, the acceleration information and the speed information of the target object respectively, and calculates the motion trajectory information of the target object according to the posture information, the acceleration information, the speed information and the preset base point position information. Without need for the satellite navigation system, the device can accurately acquire the position information and the motion track information of the target objectindoors, and realize indoor positioning and trajectory tracking.

Description

technical field [0001] The invention relates to the technical field of intelligent positioning, in particular to an indoor positioning and trajectory tracking device, system and method. Background technique [0002] In recent years, as people have more and more needs for positioning, the application of providing services based on location information has become more and more extensive. Outdoors, global satellite navigation systems such as the Global Positioning System provide people with precise positioning information. Indoors, due to the occlusion of buildings, the received signal is easily interfered by external signals or obstacles, and it is difficult for users to receive satellite positioning signals, or the received satellite signals are unstable, so they cannot stably obtain accurate indoor positioning information. In addition, during indoor positioning, the selection requirements of measurement points are relatively strict, resulting in cumbersome indoor positionin...
