2014无线电电子设计大赛 题 目： NRF24L01的收发信号 队 号： 三个烙铁匠 队 员： 王晖 曹恒 万东胜 摘要 随着现代电子技术的飞速发展，通信技术也取得了长足的进步。在无线通信领域,越来越多的通信产品大量涌现出来。但设计无线数据传输产品往往需要相当的无线电专业知识和价格高昂的专业设备，因而影响了用户的使用和新产品的开发。nRF24L01是一个为433MHz　ISM频段设计的无线收发芯片，它为短距离无线数据传输应用提供了较好的解决办法, 使用nRF24L01降低了开发难度，缩短了开发周期，使产品能更快地推向市场。本文提出了一种应用于无线数据收发系统的设计思路及实现方案，给出了基于无线射频芯片nRF24L01和STC89C52单片机的无线数据传输模块的设计方法,详细分析了各部分实现原理，并对系统的传输距离、传输数据的正确性进行了测试。试验表明，该系统性能稳定，具有较强的抗干扰能力，有较强的实用价值。 关键词：无线通信；无线数据传输模块；单片机；射频 Abstract With the rapid development of modern electronic technology, communication technology has also made great progress. In the field of wireless communication, more and more communication products have sprung up in large quantities. But the design of wireless data transmission products often require considerable radio of the high price of professional knowledge and professional equipment, thus affecting the users use and development of new products. NRF24L01 is a designed for 433 MHZ ISM band wireless transceiver chip, it for the short distance wireless data transmission application provides a better solution, using nRF24L01 reduces the development difficulty, shorten the development cycle, can make the product to market faster. This paper puts forward a kind of applied to wireless data transceiver system design idea and implementation scheme, and is given based on wireless rf chip nRF24L01 and STC89C52 single-chip wireless data transmission module, the design method of the realization principle of each part are analyzed in detail, and the transmission distance of the system, the correctness of the data transmission was tested. Tests show that the system performance is stable, strong anti-interference ability, a strong practical value.
