摘　　要：为了满足数字无线电设备的小型化和信号监测要求,基于PC104总线的高效数据传输特点,采用了上位机监测模块、信号采集解码模块以及PC104总线控制模块相结合的嵌入式系统搭建方法。数字无线电信号经过采集解码模块后,由总线控制模块完成数据在嵌入式处理器和上位机处理器之间的传输,最终在上位机监测模块进行显示。应用结果表明,该实时信号采集处理系统操作简单,具有较高的实时性和稳定性。To meet the need of portability and signal acquisition for Digital Radio Mondiale （DRM） equipment, an em- bedded system is set up by combing signal acquisition and decoding module, host computer monitor module and PC104 bus control module, taking advantage of high data transmission efficiency on PC104 bus. Signal data is acquired and decoded by signal acquisition and decoding module. Data transmission between embedded CPU and host computer CPU is completed by PC104 bus control module. Finally the signal data is displayed on host computer monitor module. Application result shows that the system is easy to operate,which performs well on real time and stability.
