Positioning circuit, positioning system and positioning method based on Bluetooth AOA communication

Abstract

The invention discloses a positioning circuit based on Bluetooth AOA communication, a positioning system based on Bluetooth AOA communication and a positioning method based on Bluetooth AOA communication. The positioning circuit comprises a radio frequency communication module, a switch switching module, a Bluetooth communication module, a calibration compensation module and a positioning controlmodule. The switch switching module outputs a driving signal according to the control signal and the radio frequency signal. The plurality of antenna units are respectively located at preset positionsand are driven by the driving signal to sequentially receive the first Bluetooth communication signal. The calibration compensation module calibrates the communication state of each antenna unit to obtain a corresponding phase compensation value. The positioning control module obtains an angle value and a distance value of the to-be-tested equipment according to the phase difference of the multiple paths of first Bluetooth communication signals after phase compensation so as to complete a positioning function on the to-be-tested equipment. The positioning circuit directly obtains the positionof the to-be-measured equipment according to the phase difference, thereby saving the intermediate variable, simplifying the positioning measurement steps, and improving the positioning precision andpositioning efficiency.
