毕业论文(设计) 论文题目: 基于单片机控制的 LED 应急灯的研究学生姓名: 所在院系: 所学专业: 应用电子技术教育导师姓名: 完成时间: 摘要本文阐述了 LED 应急灯采用单片机控制的设计原理与实现方法。先分析应急灯技术概况,提出采用 LED 照明的优点,该照明控制系统的主控制器以 AT89C2051 单片机为基础。根据相关技术规范的要求,在完成传统应急灯基本控制要求的基础上,完善电路的控制要求,增加辅助控制功能,提高电路的可控性和可视性。主控制器在接收到外部电路送来的信号后,发出命令控制应急灯实现开启、关闭、定时放电控制等功能。关键字: LED ,应急灯,单片机 The Control System for LED Emergency light Based on Single – chip puter Abstract The paper expatiates on the designing theories and implementation method of the control system for LED Emergency light by Single-Chip puter . Analyzes the emergency light technology survey first, proposed that uses the LED illumination the merit, The host controller of the control system for lighting is based on AT89C2051 Single-Chip puter 。 According to the correlation technique standard's request, pletes the traditional emergency light basic control request in the foundation, the perfect electric circuit's control request, increases the secondary control function. Enhances electric circuit's controllability and the viewability . The master-control unit after receiving the signal which exterior electric circuit sends, sends out mand control emergency light to realize opening, the closure, functions and soon timed electric discharge control . Key words : LED , Emergency light , Single –C hip puter 目录 1绪论............................................................................................................................ 1 2传统应急灯的分析.................................................................................................... 1 传统应急灯的结构和使用中的不足.............................................................. 1 原因分析及改进方法...................................................................................... 2 3设计方案的研究........................................................................................................ 3 系统设计分析.................................................................................................. 3 系统设计要点与结构.................................................
