摘要
结合无线通信技术和USB技术的优点,提出一种基于无线USB技术的数据采集系统。该系统运用高速转换器AD7874、USB接口芯片PDIUSBD12、89C51微处理器和射频收发器nRF401构建数据采集电路和无线USB接口。该设计成功取代有线数据采集系统复杂的连线,并且提高了数据采集的抗干扰性、灵活性。文中对无线A/D转换电路、无线USB接口的设计、89C51内部固件程序及USB应用程序编写进行了阐述。
Combined wireless communication with USB thchnique, a new design for wireless data acquisition system based USB is presented in this paper. The system which consists of converter AD7874, RF transceiver nRF401, MCU 89C51 and USB controller PDIUSBD12 can replace the present complicated wiring and improve the anti-jamming performance and flexibility in data acquisition. The whole project includes the design of A/D converter and wireless USB interface circuit, the firmware of 89C51 and the application program of USB device.
