文档介绍：本科毕业论文( 20 13 届) 题目基于单片机的激光通信仪学院专业光信息科学与技术班级学号学生姓名指导教师完成日期 2013 年 5月摘要无线激光通信比起传统无线电通信有许多优势,尤其是在高数据速率。随着信息时代不断发展,只靠电信号传输数据已经满足不了人类日益剧增的需求,而光通信更大程度上能实现要求,比如光纤到户等等。本论文主要对单片机激光通信系统的原理,单片机的应用等进行了分析;对 AD 转换,串口通信,激光收发器, LED 灯送显,硬件制作和软件设计进行分析;对系统进行误差分析。经过实验的证明,本论文设计的系统软件和硬件设计的很合理、实时性很好, 抗干扰的能力强。实验误差的显示表明,本设计在进行短距离的测量时误差比较小,所以可以应用在简单的数据传送等方面。关键词: PIC16F877A ;激光;通信; LED 显示; AD 转换 ABSTRACT Wireless munication has many advantages over traditional munication especially in high data the faster and fater development of the information age,the electrical pulse signal transmission data can not meet the demand of the growing surge of greater degree,munication can realize the requirements,such as fiber to the home,and so laser transceiver,ADC,master synchronous serial port,LED data show the principle of wireless munication hardware,software design and production were discussed. The research has led to the discovery that the software and hardware designing is justified,the anti-petence is powerful and the real-time capability is satis - factory . Experiments show that this error display design in short distance measurement error is less,so it can be used ina simple data transter.
