摘　　要：设计了以MSP430单片机和nRF905无线收发模块为核心的嵌入式数据集中器和数据采集器。介绍了MSP430的SPI驱动、nRF905的SPI驱动及其接口实现,阐述了链路控制方案和实际应用中应注意的问题。实现了数据采集器与数据集中器之间高效而稳定的无线数据传输,具有应用灵活、成本低廉、工程建设周期短等优点,可广泛应用于多种场合。An embedded data concentrator and data acquisition which use MSP430 Micro Control Unit （MCU） and nRFg05 wireless data communication module as the core is designed. The MSP430 Serial Peripheral Interface（SPI） driver, nRF905 SPI driver and its interface implementation are introduced and its link control program and several issues that should be focused on in practical applications are expounded. The efficient and stable wireless data transmission between data acquisitions and data concentrator is real- ized. The designed system has the advantages of flexibility, low cost, short cycle of construction, etc. So it can be widely used in various occasions.
