大多数用电器的开关都是手动控制的，在使用过程中存在着诸多的不便。为了解决这个问题，本文提出了一个多功能遥控器的设计方案。其可以通过自学习而拥有对多台用电器的遥控功能，省时省力，从而使人们免除为了控制用电器而东跑西转的烦恼。本文采用单片机AT89S51为核心，外加调频收发电路、继电器的驱动等电路组成,实现无线多路遥控开关的设计功能。-Most use of electrical switches are manually controlled, in the course there are many inconveniences. To solve this problem, this paper presents a multi-function remote control design. Their own learning through self-use of electrical appliances for more than one remote control, saving time and effort, so that people exempt in order to control electrical and rushed about here and turn with worry. In this paper, AT89S51 microcontroller core, plus FM transceiver circuit, relay drivers and other circuit components, wireless multi-channel remote control switch design features.
