Embodiment Construction

[0025] The present invention mainly starts from the method of combining wireless beacons and inertial navigation, by increasing the content of information sent by wireless beacons, it provides a variety of reference frame information for sensors, thereby solving the shortcomings of single beacon instability and large cumulative error of single inertial navigation , to improve the accuracy of indoor positioning.

[0026] In the accompanying drawings of the description of the present invention, figure 1 Schematic diagram of the composition of the indoor positioning system. The indoor positioning system of the present invention includes: a wireless beacon system, a mobile terminal system, and a cloud server system, and the wireless beacon system further includes at least one wireless beacon, that is, wireless beacon 1 to wireless beacon n. The wireless beacon system and the mobile terminal system communicate through Bluetooth 4.0, and the mobile terminal system and the cloud ser...

Abstract

The invention provides an indoor positioning system and method based on wireless beacons. Based on a wireless beacon and inertial navigation combined method, information contents sent by the wireless beacons are added, and calibration data is included in each wireless beacon to realize real-time calibration, and therefore, the defects of instability of the single beacon and large accumulated errors of single initial navigation are solved and the accuracy of indoor positioning is improved. Each wireless beacon is integrated with an infrared sensor for sensing a moving object in real time, and only after the moving object is sensed, a radio-frequency signal is sent; in this way, the power consumption can be effectively reduced and the service time of the battery of the wireless beacon can be increased, and furthermore, the labor and material costs can be saved.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a wireless beacon-based indoor positioning system and method. Background technique [0002] Indoor positioning technology is becoming a hot spot in market competition. As long as the indoor location can be successfully combined with user data or information that users are interested in, indoor positioning will have a very broad application prospect. Indoor positioning will become one of the most important entrances in the era of mobile internet. [0003] At present, the main indoor positioning solutions can be divided into two categories: wireless beacon indoor positioning and inertial navigation positioning. [0004] Indoor positioning of wireless beacons: use various wireless devices in the room to locate the target position by receiving information such as the strength of the wireless signal. For example, the invention patent application with the application num...
