This embodiment revises bluetooth signal intensity through the angle that uses bluetooth signal reception angle, acquires comprehensive bluetooth signal intensity to improve bluetooth location precision. The bluetooth detection unit 21 calculates a signal with the maximum integrated bluetooth signal intensity, and then sends the mobile phone bluetooth MAC address information corresponding to the mobile phone with the maximum integrated bluetooth signal intensity to the background server 30 through the background communication unit 22.
The angle of the bluetooth signal receiving angle can be measured by an angle-of-arrival angle measurement mode (AOA) or an angle-of-departure angle measurement mode (AOD).
If two or three adjacent vehicles stop simultaneously and cannot be judged by the rssi value of the Bluetooth signal accurately, the user can confirm to input the number of the parking position. (in case the geomagnetic detection unit detects that there is a vehicle parking in the parking space, it informs the Bluetooth unit to broadcast the information that there is a vehicle parking in its position through its broadcast channel, the user stops the vehicle, opens APP, or the applet or the public number will automatically confirm the position of parking, if the APP of the user detects that there is a vehicle parking in two or three positions simultaneously, then the user is required to confirm the specific parking space that is parked)
