摘 要

    隨著電子技術的飛速發(fā)展，基于單片機的控制系統(tǒng)已廣泛應用于工業(yè)、農業(yè)、電力、電子、智能樓宇等行業(yè)，微型計算機作為嵌入式控制系統(tǒng)的主體與核心，代替了傳統(tǒng)的控制系統(tǒng)的常規(guī)電子線路。同時樓宇智能化的發(fā)展與成熟，也為基于單片機的照明控制系統(tǒng)的普及與應用奠定了堅實的基礎。
    本文闡述了照明的有線、無線控制方式設計原理與實現方法。以設計過程為主線，分別從硬件和軟件兩個方面描述設計過程，即從硬件電路的設計方法到實現所要求功能的軟件技術。該照明控制系統(tǒng)的主控制器、分控制器分別是以AT89C51與AT89C2051單片機為基礎，實現了有線通信、無線數傳、控制與顯示等功能。文中詳細地描述了控制電路的設計過程，包括：鍵盤與LED顯示電路、RS485通信電路、無線數傳電路、照明燈控制電路以及看門狗電路等。對于軟件設計主要有主控制器、分控制器的有線通信程序設計與無線數字傳輸程序設計以及燈光控制、定時控制、鍵盤掃描與LED顯示等程序設計。有線通信程序的功能是：通過RS485主從通信方式，由主控制器發(fā)出命令對全部或單個分控制器所控制的照明燈實現開啟、關閉、燈光亮度調節(jié)、定時控制等功能。無線數傳程序設計的功能是：通過無線數傳模塊實現照明燈的無線遙控，同樣實現有線方式控制的功能。

 The Control System for Lighting Based on
 Single–chip Microcomputer
 
 Abstract
 
            With the rapid development of electronic technology, the system of control based on Single-chip Microcomputer is widely applied in industry, agriculture, electric power, electron, intelligent building and so on. Microcomputer, as the subject and core of the embedded system of control, replaces the traditional system—electronic circuit. At the same time, the development and maturation of the intelligent building have established the substantial foundation for the popularization and application of the control system for lighting based on single-chip microcomputer.
              The paper expatiates on the designing theories and implementation method of the control system for lighting by wired or wireless communications. Taking the designing process as mainline, it describes the process of designing from two respects—hardware and software.  In another word, the paper describes the process from the method of circuit designing to the software technology of realizing the demanded functions. The host controller of the control system for lighting is based on AT89C51 single-chip microcomputer, and the auxiliary ones are based on AT89C2051. The system can do many jobs, such as wired communication, wireless data transmitting, controlling and display. The paper describes the designing process of the circuit at length, including: keyboard and LED display circuit, RS485 communication circuit, wireless transmitting circuit, control circuit of lighting, watchdog circuit, etc. The designing of software mainly includes the several programming, such as wired communication, wireless data transmitting, lamplight controlling, timed controlling, keyboard scanning and LED displaying. The wired communication programming function is that through Master-slave communication method based on RS485 the host controller sends orders to the all auxiliary controllers or each one, including: turning on lighting, turning off lighting, regulating brightness of lighting, controlling timed lighting, etc. The wireless data transmitting programming function is that by wireless transmitter it realizes wireless controlling of the lighting, and achieves the functions identical to wired communication.
