摘要：随着科学技术的不断发展，智能家居在当今社会中得到了快速的发展和应用。智能化的家用电器已经成为了如今家庭中必不可少的部分，它的安全高效、方便快捷、节约能源等众多优点使得它比传统的电器更加的出色，也更加地受到人们的欢迎。而使用单片机作为现在智能家居的中央控制系统，使得智能家用电器更加的安全可靠，效率也越来越高，极大地方便了人们的生活。

本次设计研究的是智能儿童台灯系统，它利用Arduino、超声波感应模块、蜂鸣器、LCD1602显示模块以及WIFI模块对台灯进行控制来实现各种功能。当超声波模块检测到孩子打开台灯或者离开台灯时，控制器会通过WIFI模块发送到新浪云服务器中并将数据保存在数据库之中，家长可以通过微信来接收数据，查看孩子的学习状况。

系统采用的是Arduino作为中央控制器，它通过串行接口与超声波模块、蜂鸣器、按键模块、LCD1602显示模块实现通讯，可以实现自动开关、靠近报警、显示时间以及存储数据的功能。智能儿童台灯的设计，给孩子一个健康、安全、舒适的学习环境，也为家长提供了一个快捷方便的监督平台，将来必将成为智能家用电器中的主流。

Abstract：  With the continuous progress of science and technology, smart home in today's society has been rapid development and application. Intelligent household appliances has become an indispensable part of the family today, it's safe and efficient, convenient, energy saving and many other advantages make it more than the traditional electrical appliances more and more popular by the people. The use of single-chip smart home as the central control system, making smart home appliances more secure and reliable, more efficient, greatly facilitate the people's lives. And the rapid development of single-chip smart home more and more tend to miniaturization.

This design is the intelligent children's lamp system, which uses Arduino, ultrasonic sensor module, buzzer, LCD1602 display module and WIFI module to control the lamp to achieve a variety of functions. WeChat platform is the user to accept the data side, Arduino controller first data transmission to the Sina cloud server, through the database processing to real-time data transmission to the WeChat platform, the user can also send a request to the server through the micro-server to obtain data in the database.

The system uses Arduino as a central controller, which through the serial interface and ultrasonic modules, buzzer, key module, LCD1602 display module to achieve communication. Can automatically switch, close to the alarm, display time and the function of storing data. Intelligent children's lamp design, to the children a healthy, safe and comfortable learning environment, but also for parents to provide a fast and convenient monitoring platform, the future will become the mainstream of smart home appliances.

Key words: single-chip (Arduino); ultrasonic module; WeChat platform; LCD1602 display module；
