红外通信发射系统设计讲解VIP免费

红外通信发射系统设计摘 要红外通信是目前比较常用的一种无线数据传输手段，其具有无污染、信息传输稳定、 信息安全性高以及安装使用方便等优点，并且可以在很多场合应用，如家电产品，工业 控制、娱乐设施等领域。红外发射接收对管具有功耗小，价格低，效率高，传输距离适 中，体积小，编解码技术简单等突出特点，在家用电器遥控设备、农业大棚温度管理、 工业现场温度采集等方面得到了广泛的应用。本论文主要就是设计并制作一种以 51 单片机为基础的红外通信发射系统，采集周围 环境的温度，电压信号。然后将采集到的温度信号、电压信号、通过 51 单片机进行编码 调制，放在 38KHZ 载波信号中发射出去，借此实现实时采集现场的温度信号和电压信号 的红外调制发射。整个发射系统使用 Piotues 进行了仿真测试，验证了整个实验设计的合 理有效，能够正常工作实现预定的目标。关键词：无线通信；温度采集；AD 电压采集；38KHZ 载波信号调制Infrared communication system designABSTRACTIiifiared Coniiiiunication is now more commonly used a wireless data Uansmission means, which has no pollution, information transmission stability, high safety and convenient installation, and can be applied ill many occasions, such as home appliances, industrial control, ente∏aiιuιιent facilities, and other fields. Infiaied Coniniunicatioii for a long time, but into the 90 s, the communication teclιnology and the new development, application scope is more extensive Infiaied receiving tube with low consumption, low price, high efficiency, the transmission distance is moderate, small volume, simple decoding tecluιology such as outstanding characteristics, in household appliances remote contιol equipment, agricultural greenlιouse tenιpeιatuιe management, industrial ∩eld temperature has been widely used.This thesis mainly is to design and produce a kind of infiaιed communication release system based on 51 single chip nιicιocomputer, collect the tempeιatuιe of the suπoundiιιg enviιonnιent...
