摘　　要：介绍一种基于MCU和nRF905的低功耗远距离无线传输系统,描述了系统设计软硬件的实现方法和多点传输数据的通信协议。系统主控芯片采用通用的低功耗MCU芯片MSP430,射频芯片采用具有多信道的单片收发芯片nRF905。同时提出了跳频机制保证数据传输的可靠性,增加了系统的鲁棒性。A low-power long-range wireless data transmission platform based on MCU and nRF905 chip is presented in this paper. The design method of the software and hardware, together with the MAC protocol of multiple-points transmission is introduced in detail. The platform adopts MSP430 as the main control MCU and the multi-channel single chip transceiver nRF905 as the radio frequency IC. Frequency hopping is applied to improve the reliability of data transmission.
