摘要
针对电视遥控器的一种无键设计,该系统主要采用微机械加速度计做感应元件来获取二维的摆动信号,信号处理采用单片机控制,最后通过红外发射模块来实现对电视相应的操作控制。该设计包括硬件和软件两部分,实现对电视音量和频道的基本控制。该产品体积小,由电池供电,外观设计灵活性强,操作方便,对其不同程度的改变,可适用于不同应用场合。
The keyless design based on accelerometer is for TV remote control.The system obtains two-dimensional swing signal mainly by using micro-accelerometer as induction element.MCU controls the signal processing,using infrared sending module realizes corresponding operation control of TV.The design includes hardware and software,implements basis control for volume of sound and frequency channel.The product has small volume,cell supply power,external design flexible,and easy to operate,truly realizes simple control,changing it in varying degrees can suit to different applications.
