| 摘 要： | 由于传统的数据采集系统与PC机接口的种种缺陷，文中利用FPGA（现场可编程门阵列）和USB2．0接口芯片CY7C68013设计了基于USB2．0接口的实验数据采集系统，并且考虑到USB的传输距离有限，还利用网络来实现数据的远程传输，从而实现现场实验数据的采集和监控。最后对系统进行整体测试，验证了系统基本功能的正确性。

| Abstract: | Because of the limitations of the interface by which the traditional data acquisition systems are connected with PC, in this paper we use Field Programmable Gate Array and USB 2.0 interface chip CY7C68013, to design a data acquisition system based on USB 2.0 interface. Meanwhile, considering the limited transmission distance of USB, this paper realizes the remote transmission by means of network. Therefore we can realize the acquisition of remote experimental data. In the end, the whole system is tested and the correctness of functions of the system are validated. |
