随着科学技术突飞的发展,无线化已经成为电子技术的一个重要发展方向。简要介绍了无线通信基础知识,接着对组成系统的每个功能模块进行拆分设计,并对射频芯片nRF905的结构和工作原理作了简要的介绍,开发了硬件电路、外围工艺和数据无线收发程序。最后对数据无线传输距离进行理论计算和分析。
Along with the development of science,the wireless technique has already been an important development derection of electronics technique. This design introduces foundation knowledge of the wireless didital design which constitutes each piece of function of the system, and introduces the structure and the work principles of the main component of the radio frequency chip nRFg05. The development includes the hardware electric circuit, the outer circle craft and the procedure of the data wireless to receive and dispatch. Finally carrying on the theories calculation and analysis on the diagraph.
