摘　　要：无线数据传输现在广泛地运用在各种控制领域。该系统中采用由无线收发芯片nRF401配合外围电路的射频模块来完成数据的传输;通过对Bootloader硬件的初始化后,实现将μClinux裁减并移植到S3C44B0中,最后用嵌入式处理器程序来实现对传输数据的处理和存储、网络通信、外部控制等任务。经过测试通信距离为80m,无线通信最高速率可达到20Kb/s。The wireless data transmission is now widely used in various areas of control.The wireless transceiver chip nRF401 matched up with RF modules of peripheral circuits is adopted in the system to complete the data transmission.By the initialization of Bootloader hardware,uClinux is cut down and transplanted into S3C44B0.The embedded processor program is employed to achieve the processing and storage of the transmitted data,network communication,external control,and other tasks.The testing result indicates that the communication distance is 80 m,and the highest velocity of wireless communication is up to 20 Kb/s.
