摘要
介绍了平时生活中各种不同设备的遥控带来不少麻烦和问题,而现有的万能遥控器数据压缩率低、响应时间长、学习类型少。通过分析研究,针对红外、无线这两种主流的遥控方式,进一步提出一种基于低功耗32位单片机EFM32GG230的自学习系统,对红外无线数据进行压缩存储,并通过多通道转发电路进行信号发射。本系统具有低功耗、自学习范围广、信号集中控制、数据压缩率高、一键多发多控等优点,可以为人们的生活带来便利,让遥控不再繁杂。
In normal life,the remote controls of various devices bring many troubles and problems,and the existing universal remote con-trollers have some drawbacks such as low compression rate of data,long response time and less learning type.Aiming at the infrared and wireless mainstream remote controls,this paper proposes a self-learning system based on 32-bit MCU EFM32GG230,which compresses and storages the infrared and wireless data,and transmits the signals through multi-channel transmission circuit.The system has such advantages as low power consumption,wide self-learning range,centralized control for signals,high compression rate of data and multi-ple controls by one key.The design brings convenience to people＆#39;s life and makes the remote control simple.
