设计简介：
项目名：儿童防丢器
项目编号：mcuclub-dz-297
单片机类型：STM32F103C8T6
具体功能：
1、通过蓝牙连接主从机
2、第一次连接后，每隔1s从机向主机发送一次数据，主机如果接收到数据，则表明儿童在附近，如果主机和从机距离远或从机断线，都会导致主机接收不到数据，则主机进行声光报警
3、通过GPS进行定位，当蓝牙断开后，通过GSM将定位以短信形式发送到手机端

摘 要
在实际生活中，年轻父母在陪伴儿童玩耍的过程中，由于注意力不集中，导致儿童走失的现象屡屡发生，产生一个一个的家庭悲剧，在这样的背景下，为了防止儿童丢失所带来的家庭悲剧，设计一款智能无线儿童防丢器极为关键。
该系统由主机机和从机机两部分组成，通过蓝牙模块连接主从机，主从机连接成功后，主机负责接收子机信号，从机负责发送信号，每隔1s从机向主机发送一次数据。如果主机接收到数据，则表明儿童在附近，如果主机和从机一旦距离超出预订范围或从机断线，都会导致主机接收不到数据，主机进行声光报警发出报警信号提醒家长，进行寻找儿童，实物测试表明，该儿童追踪系统价格低廉、操作方便，具有较好的市场前景。

Abstract
In real life, young parents in the process of accompanying children to play, due to lack of attention, resulting in the phenomenon of children lost frequently occurs, resulting in a family tragedy, in this context, in order to prevent the loss of children brought by the family tragedy, the design of an intelligent wireless child loss prevention device is extremely critical.
The system consists of two parts: the host machine and the slave machine. The master and slave machines are connected through the Bluetooth module. After the master and slave machines are connected successfully, the host machine is responsible for receiving the signal of the child machine, and the slave machine is responsible for sending the signal, and the slave machine sends the data to the host machine every 1s. If the host receives data, it indicates that the child is nearby, if the host and the slave machine once the distance exceeds the reservation range or the slave machine is disconnected, it will lead to the host to receive no data, the host sound and light alarm sends an alarm signal to remind parents to find children, physical tests show that the child tracking system is cheap, easy to operate, and has good market prospects.
