摘　　要：为了满足实验室高性能和分布式数据采集系统的要求,采用浮点DSP芯片设计了嵌入式系统,其硬件系统配备高精度的模拟量输入,具有大容量存储单元,通信单元采用USB接口和CAN总线,系统软件基于状态机的方法设计。使用结果证明,该数据采集系统具有很高的采样精度和快速数据通信功能,在水动力试验中得到成功的应用。In order to meet the demands of high performance and distributed data acquisition system in laboratory, a new design of embedded system based on floating-point DSP is developed. The system possesses high precision analog input and a large-capacity storage module. Its communication module uses CAN technology and serial port in the form of USB port. State machine is proposed in the system software. The results show that the data acquisition system has high sampling accuracy and fast data communication. And it has been applied successfully to the water dynamic research.
