摘 要

当下物联网发展日星月异，各类智能化设施的涌现，不断影响和推进着人们的生产生活。同时在现代化的知识背景下，随着人们知识广度的不断延伸，对于照明系统人们更加追求高质量的照明效果和舒适的即时体验。因此各类照明控制系统以其各自不同的优势相继产生。

本文以节能降耗、智能控制为目的，使用了一种易连接、管理方便、使用广泛且能耗低的无线通讯方式—蓝牙技术。同时以功能强大的STC89C52单片机来展开研究。主要设计内容有：（1）以单片机为核心，加上传感器电路、蓝牙模块和电源模块等外围输入电路实现自动和无线手动两种方式操纵灯光。（2）利用红外传感器感应人体，加上光敏传感器对自然光强度的检测功能，联合控制是否开灯与开灯后的灯光亮度强弱情况，使得灯光在多重因素的影响下，也可以合理使用。（3）通过设置，使蓝牙模块进入工作状态，并与单片机完成连接通讯。进而可以使用手机APP界面操作灯光，实现无线通信下的控制。（4）多种方式的控制使灯光的亮度控制更加直接，解决了高校教室、办公楼、政府机关等公共场所的“长明灯”现象。从而实现节能、低耗、高效利用资源的愿望。

Design and Implementation of Intelligent Light Control System

Abstract

The current development of the Internet of Things is changing day by day, and the emergence of various types of intelligent facilities continues to affect and promote people's production and life. At the same time, under the background of modern knowledge, with the continuous extension of people's knowledge, people are more pursuing high-quality lighting effects and comfortable instant experience for lighting systems. Therefore, various types of lighting control systems are produced in succession with their respective advantages.

For the purpose of energy saving, intelligent control, this paper uses a wireless communication method-Bluetooth, which is easy to connect, convenient to manage, widely used and low in energy consumption. At the same time, the powerful STC89C52 single-chip microcomputer is used for research. The main design contents are as follows: (1) Take the single chip microcomputer as the core, and add peripheral circuits such as sensor circuit, Bluetooth module and power module to realize automatic and wireless manual operation of the light. (2) The infrared sensor is used to sense the human body, and the light sensor detects the natural light intensity to jointly control whether the light is turned on and the brightness of the light after the light is turned on, so that the light can also be used reasonably under the influence of multiple factors. (3) Through the setting, make the Bluetooth module enter the working state, and complete the connection and communication with the single chip microcomputer. Furthermore, you can use the mobile phone APP interface to operate the lights to achieve control under wireless communication. (4) The control of various modes makes the brightness control of the lights more direct, and solves the phenomenon of "long lights" in public places such as university classrooms, office buildings, and government offices. In order to achieve the desire of energy saving, low consumption and efficient use of resources.
