介绍了一种基于单片微处理器AT89C51控制的无线数据传输系统的设计方法,系统设计以Nordic nRF401收发一体芯片为核心,分析了nRF401的性能参数、系统结构和使用方法。提出了无线数据传输系统的软、硬件设计方案,并给出了系统低功耗、可靠性的设计实现方法。利用该方案设计的系统具有发射功率小,外围元件少等特点,可满足低功耗、微型化的无线数据传输产品的设计需求。
A design method of wireless data transmission system based on single chip microprocessor AT89C51 is introduced. The system design is based on the Nordic nRF401 transceiver chip, and the performance parameters, system structure and usage of nRF401 are analyzed. Proposed a wireless data transmission system software and hardware design, and gives the system low-power, reliability design and implementation methods. The system designed with this scheme has the characteristics of small transmitting power and few peripheral components to meet the design requirements of low power consumption and miniaturized wireless data transmission products.
