摘　　要：在无线电脑遥控器的基础上,利用NRF24E1设计了带语音传输和带手写板传输的无线遥控系统。针对按键、语音和手写板3种不同数据的特点,对数据进行复用,制定了数据传输协议;为了保证数据的实时传输,采用ISM频段进行数据的传输;不同的系统采用频分复用,可以实现多套系统的无干扰传输。给出了系统设计框图、硬件原理图和软件流程,并对系统的功能进行了测试。研究表明该系统能够同时实现无线智能键盘、无线手写板和无线语音的功能。Based on a wireless computer remote control, designed a wireless remote control system with voice transmission and table data transmission using NRF24E1. According to the different characteristics of press data、speech data and the table data,the data were multiplexed,developed a data transfer protocol. To ensure that the data real-time transmission,ISM band used to transmit data. Frequency division multiplexing used in different systems, Which can achieve interference free transmission in many systems. The system design, the hardware schematic diagram and the software flow were given out, and the function of the system was tested. Studies show that the system can realize intelligent wireless keyboard, wireless tablet and wireless voice function.
