The present invention relates to a method for improving the positioning accuracy and alarm performance of a Bluetooth anti-loss device by using a mobile terminal. The method comprises: step 1, the mobile terminal searches for a Bluetooth anti-loss device and successfully carries out connection and binding with the Bluetooth anti-loss device; step 2, the Bluetooth anti-loss device reports signals every second; step 3, after receiving the signals, the mobile terminal analyzes the intensity values of the signals reported by the Bluetooth anti-loss device and makes a judgment; step 4, arranging a fixed signal value as an alarm reference value on the mobile terminal, and when the signal values in more than two times, continuously reported by the Bluetooth anti-loss device and selected by the mobile terminal, exceed an alarm reference value, the mobile terminal rapidly transmits an alarm starting instruction to device; and step 5, simultaneously perform alarming on the mobile terminal and the Bluetooth anti-loss device to prompt that the mobile terminal and the Bluetooth anti-loss device go beyond a safety distance. By using the present invention, positioning and alarm functions of the Bluetooth anti-loss device and the mobile terminal can be more accurately implemented, a false alarm or missed alarm phenomenon generated due to frequency floating of Bluetooth signals is avoided, and the present invention can be better adapted to influences of various entertainment places with many people such as indoor and outdoor places and the like on the intensity of the Bluetooth signals, and the Bluetooth anti-loss functions for articles are better implemented. |
