摘 要
儿童安全与健康发展关乎家庭幸福和社会稳定。近些年来儿童走失、拐卖孩童案件层出不穷，严重威胁了家长和儿童的切身利益。因此，本文针对儿童走失走散问题，以 儿童为研究对象，以防走失为目的，以理论为基础，为该类产品的设计开发提供新的设计思路。本文设计一款基于STC89C52智能无线儿童防丢器。该系统由母机和子机两部分组成，母机负责接收子机信号，一旦距离超出范围，发出报警信号提醒家长，同时查找儿童，子机负责发送信号。该系统价格低廉、操作方便，具有较好的市场前景。

Abstract
The safety and healthy development of children has a bearing on family happiness and social stability. In recent years, the cases of children lost and abducted emerge in endlessly, which seriously threaten the vital interests of parents and children. Therefore, aiming at the problem of children getting lost and separated, this paper takes children as the research object and aims to prevent them from getting lost. Based on the theory, this paper provides a new design idea for the design and development of such products. This paper designs an intelligent wireless children’s anti-loss device based on STC89C52. The system consists of two parts: the mother machine and the child machine. The mother machine is responsible for receiving the child machine signal. Once the distance is out of range, it sends an alarm signal to remind the parents. The system is cheap, easy to operate and has a good market prospect.
