通过对DL-20无线通信模块、光敏电阻、HC-SR501人体红外感应模块和STC89C52单片机的研究,提出一种智能照明控制系统的设计方案。该系统由控制终端和主机两个部分组成。控制终端能够根据环境的光照强度及是否有人出现在监控范围内,对照明灯的亮灭进行自动控制,并能控制无线通信模块工作,将当前终端的系统运行状态信息发送给主机;主机用于显示各终端的当前的运行信息,并能下发控制命令,对每个控制终端照明灯进行控制。本文介绍了智能照明控制系统的实现过程,分析了系统的实现原理。与传统的控制方式相比,该方案具有功能多、处理速度快、现场应用灵活等优点。
Through the research of DL-20 wireless communication module, photosensitive resistor, HC-SR501 human body infrared sensing module and STC89C52 microcontroller, a design scheme of intelligent lighting control system is proposed. The system consists of two parts of the control terminal and the host. The control terminal can automatically control the light on and off of the lamp and control the operation of the wireless communication module according to the light intensity of the environment and whether or not someone is in the monitoring range and send the system running status information of the current terminal to the host computer; Current operation information of each terminal, and can issue control commands to control the lighting of each control terminal. This article introduces the realization process of intelligent lighting control system and analyzes the realization principle of the system. Compared with the traditional control methods, the program has the advantages of multiple functions, fast processing speed and flexible field application.
