基于单片机的防丢器的设计与实现

Design and Implementation of Anti-loss Device Based on Single Chip Microcomputer

随着生活快节奏时代的到来,因为遗忘、窃贼等原因而造成遗失贵重物品的经历,为我们造成了巨大的困扰,运用蓝牙技术的防丢器的设计解决了这一问题。运用STC89C52单片机进行控制,使用方式简单易操作,打开焊接的子机电路板,连接电源,与主机(手机)的蓝牙进行连接,主机与子机之间通过H5-05蓝牙模块进行无线电信号的发出与接收,进行数据的实时交互。主机与子机的距离超过一定限度,主机会因为接收不到信号而判定丢失或者遗落发出提示报警,发挥出防丢的功能。

Losing valuables due to forgetting,thieves and other reasons is causing people great trouble in the fast pacing era.The design of the anti-loss device using Bluetooth technology solves this problem.STC89C52 single chip microcomputer is used for control.The operation mode is simple and easy.One just pens the circuit board of the welding sub machine,connects the power supply,and the Bluetooth of the host(mobile phone)is connected.Between the host and the sub machine,the radio signal is sent and received through h5-05 Bluetooth module,and the data is exchanged in real time.If the distance between the host computer and the slave computer exceeds a certain distance,the host computer will send a prompt alarm because it cannot receive the signal and judge whether it is lost or lost,so as to play the function of loss prevention.
