1、单片机的照明控制系统摘要随着电子技术的飞速发展，基于单片机的控制系统已广泛应用于工业、农业、电力、电子、智能楼宇等行业，微型计算机作为嵌入式控制系统的主体与核心，代替了传统的控制系统的常规电子线路。同时楼宇智能化的发展与成熟，也为基于单片机的照明控制系统的普及与应用奠定了坚实的基础。本文阐述了照明的有线、无线控制方式设计原理与实现方法。以设计过程为主线，分别从硬件和软件两个方面描述设计过程，即从硬件电路的设计方法到实现所要求功能的软件技术。该照明控制系统的主控制器、分控制器分别是以AT89C51与AT89C2051单片机为基础，实现了有线通信、无线数传、控制与显示等功能。文中详

2、细地描述了控制电路的设计过程，包括：键盘与LED显示电路、RS485通信电路、无线数传电路、照明灯控制电路以及看门狗电路等。对于软件设计主要有主控制器、分控制器的有线通信程序设计与无线数字传输程序设计以及灯光控制、定时控制、键盘扫描与LED显示等程序设计。有线通信程序的功能是：通过RS485主从通信方式，由主控制器发出命令对全部或单个分控制器所控制的照明灯实现开启、关闭、灯光亮度调节、定时控制等功能。无线数传程序设计的功能是：通过无线数传模块实现照明灯的无线遥控，同样实现有线方式控制的功能。关键词：主控制器，分控制器，单片机，有线通信，无线数传，灯光亮度控制，定时控制52目录摘
