远离提示电路的设计(STC89C52单片机)(论文11800字)
摘要：针对现在人们生活节奏越来越快，经常因为丢三落四、疏忽大意、被行窃等原因,造成的贵重物品丢失和孩童走失不能即时寻回的问题，本设计采用单片机微控制器对远离提示电路进行智能化改进，利用Android平台的智能手机和蓝牙技术设计一款智能防丟器。该智能防丟器由从机和主机构成,使用蓝牙无线技术连接互相通信，通过检测两者之间的信号强度来实现报警。本设计是采用高性能、低功耗的STC89C52单片机作为控制模块的核心，结合手动按键模块、电源模块、蓝牙无线模块来设计的一种智能防丢器。

Design of Remote Prompting Circuit
Abstrsct:In view of the increasingly rapid pace of life nowadays, the loss of valuables caused by the loss of valuables and the loss of children can not be recovered immediately due to the loss of valuables, negligence, theft and so on, often caused by the loss of people's lives. In this design, the MCU is used to transform the remote prompt circuit intelligently. The smart phone based on Android platform and Bluetooth technology are used to design an intelligent anti-loss device. The intelligent anti-loss device consists of a master and a slave. The slave and the host are connected by bluetooth wireless technology and communicate with each other, the alarm is realized by detecting the signal strength between them. This design uses STC89C52 MCU with high performance and low power consumption as the core of the control module, and combines manual key module, power module and Bluetooth wireless module to design a new intelligent anti-loss device.
