摘要
本设计是基于蓝牙的手机防丢报警器,它主要是由STC89C52单片机和蓝牙模块电路再加上手机接收报警模块和电源等模块共同构成。用户使用时,首先需要打开手机蓝牙模块,通过蓝牙实现和主板蓝牙的连接,当两者超过了一定的米数后,利用蓝牙防丢器进行声光共同报警。本设计的蓝牙防丢报警器具有更高的可靠性、更好的稳定性、更强的抗干扰能力、使用方便等特点。
The design is based on Bluetooth,which is composed of STC89C52 MCU,Bluetooth module circuit,mobile phone receiving alarm module and power module.When users use it,they need to open the Bluetooth module of the mobile phone and connect it with the motherboard through Bluetooth.When the two exceed a certain number of meters,they use Bluetooth Loss Prevention Device to alarm both with acousto-optic.The Bluetooth anti-loss alarm designed in this paper has the characteristics of higher reliability,better stability,stronger anti-interference ability and convenient use.
