电子信息工程毕业设计论文--多功能遥控器的设计.doc

PAGE III 摘要 由于人们的生活水平日益提高，为了减少人的工作量，对各种家用电器、电子器件的非人工控制的要求也是越来越高，针对于这种情况，设计出一种集成度比较高的控制体系是必然的。单片机的集成度很高，它具有体积小、质量轻、价格便宜、耗电少等突出特点，尤其耗电少，又可使供电电源体积小、质量轻。单片机特别适合于把它做到产品的内部，取代部分机械、电子零件或元器件。可使产品缩小体积，增强功能，实现不同程度的智能化。红外线做信号载波的优点很多：成本低、传播范围和方向可以控制、不产生电磁辐射干扰，也不易受干扰等等，因此被广泛地应用在各种技术领域中。本设计以单片机为核心设计一种学习型多功能遥控器，可以对各种红外线遥控器发射的信号进行识别、存储和再现等功能，该遥控器可以通过自学习而拥有对多台电器的遥控功能，即省时、又省力，从而使人们免除同时面对众多遥控器的烦恼。学习型多功能遥控器由单片机、红外线接收、红外线发射、显示、存储、按键和欠电压指示等部分组成。本设计详细介绍了学习型多功能遥控器的软硬件设计方法，并给出了具体的各单元电路设计、程序设计及主程序流程图。 关键词：单片机 多功能 红外线遥控器 Abstract As peoples living standards increasing, in order to reduce the workload of various household appliances, electronic devices Fei Rengong control is getting higher and higher requirements, to address this situation, to design a relatively high degree of integration of control System are inevitable. SCM high degree of integration, it has a small size, light weight, cheap, low power consumption, and other prominent feature, especially less power consumption, and allows power supply small size, light weight. SCM is especially suitable for it to the internal product to replace part of the machinery, electronic parts or components. Will narrow the volume of products, enhanced functions, to achieve different levels of intelligence. Infrared signal carrier to do a lot of advantages: low cost, scope and direction of transmission can be controlled, not produce electromagnetic radiation interference, not susceptible to interference and so on, so it is widely used in various technical fields. The microcontroller as the core design to design a learning-type remote control, infrared remote control to launch all kinds of signals recognition, storage and retrieval functions, the remote control through self-learning and multiple ownership of electrical appliances The remote-control function, that is, save time and effort, so that people from remote control at the same time face many problems. Learning from multi-function remote control microcontroller, infrared receivers, infrare
