Embodiment Construction

[0011] exist figure 1 Among them, the STM32F103 controller (1) and the Bluetooth 4.0 module (2) are connected through a serial communication interface, and the Bluetooth 4.0 module (2) obtains the information of four Beacon beacons (3) wirelessly, and feeds back the obtained information to the STM32F103 control device (1), STM32F103 controller (1) obtains the position information through calculation, and sends it to the external device through the serial port (4). Usually Beacon beacons (3) are placed in different directions in order to improve accuracy.

[0012] exist figure 2 In the flow chart shown, the system first initializes (5) and then scans the surrounding beacons (6) through the Bluetooth 4.0 module (2) to obtain information from the Beacon (3). ) information to complete the calculation of the position information (7) and finally send the information to the external device through the serial port (4) to achieve sending to the serial port (8), and at the same time,...

Abstract

The invention provides an indoor locating apparatus based on Beacon, which can particularly provide accurate position information indoors. A core board of a microprocessor with an STM32F103 control chip is used as a main controller, a Bluetooth module is connected, an LCD display screen is used as a monitoring interface, a serial communication interface is used as a locating information output interface, and four Beacon transmitters are externally arranged to provide position calibration. Signals sent by the four Beacon transmitters are collected by the Bluetooth module, and the own position information is calculated by using the STM32F103 control chip and is displayed and sent to the serial communication interface so as to realize a locating function.

Description

[0001] Technical field [0002] The invention relates to a Beacon-based indoor positioning device, especially capable of providing accurate position information indoors. Background technique [0003] At present, the mainstream indoor positioning technology mainly adopts ultrasonic positioning, visual system positioning, etc., which are deeply used in the field of indoor robot and aircraft navigation. The emergence of Beacon technology has greatly improved the accuracy of indoor positioning and reduced the cost. However, because the existing Beacon technology needs to rely on integrated devices such as mobile phones, the cost is high and the integration degree is poor. Contents of the invention [0004] In order to overcome the disadvantages of high cost and poor positioning accuracy of the existing indoor positioning technology, the present invention provides an indoor positioning device based on Beacon. The indoor positioning device can not only achieve high-precision posit...
