Bluetooth bracelet with mobile phone loss preventing function and incoming call reminding function and method

Abstract

The invention discloses a Bluetooth bracelet with the mobile phone loss preventing function and the incoming call reminding function and a method. The Bluetooth bracelet comprises an MCU, a Bluetooth antenna, a Bluetooth signal strength detection unit and a warning unit, wherein the Bluetooth antenna is connected with the MCU through a Bluetooth communication module, the Bluetooth signal strength detection unit is connected with the Bluetooth communication module, the output end of the Bluetooth signal strength detection unit is connected with the collected signal input end of the MCU, and the control signal output end of the MCU is connected with the warning unit. By means of the Bluetooth bracelet, the Bluetooth signal strength between the Bluetooth bracelet and a mobile phone can be detected automatically, when the signal strength is lower than a threshold value, the distance between the Bluetooth bracelet (a user) and the mobile phone is judged to be larger than the safe distance, then an alarm is given, and the mobile phone can be effectively prevented from being lost. The mobile phone initiatively sends a call notification to the Bluetooth bracelet through the Bluetooth, the Bluetooth bracelet reminds the user, and missing calls, messages and the like can be avoided. Circuit elements are placed separately and connected through a flexible printed circuit board to be in a chain shape. The Bluetooth bracelet is reasonable in space design, simple in structure, attractive and long in service life.
