| 摘 要： | 针对超声结构探测应用中回波信号信噪比低且动态范围大的特性,提出了一种基于分布式总线型结构的多路数据采集系统。该系统以DSP器件为控制核心,配合网络接口芯片实现了基于TCP/IP协议的节点间通信,同时在信号采集前端采用基于预采样的自动增益技术,提高了采集精度。通过测试表明,该系统具有良好的性能,具有较高的实用价值。

| Abstract: | To solve the ultrasonic signal acquisition problem in low SNR and high dynamic range,a multi-channel data acquisition system based on distributed bus structure is proposed.The DSP,which is the controller of the system,combined with the network interface chip are utlized to implement the system.Furthermore,the AGC technology based on pre-sampling is applied in the front of data acquisition system to improve the accuracy.The system is tested and the experimental results show that the system has significant va... |
