- USB、串口、并口是PC机和外设进行通讯的常用接口，但对于数据量大的图像来说，若利用串行RS-232协议进行数据采集，速度不能达到图像数据采集所需的要求；而用USB进行数据采集，虽能满足所需速度，但要求外设必须支持USB协议，而USB协议与常用工程软件的接口还不普及，给使用带来困难。有些用户为了利用标准并行口(SPP)进行数据采集，但SPP协议的150kb/s传输率对于图像数据采集，同样显得太低。因此,为了采集数据量大的图像数据,本文采用了具有较高传输速率的增强型并行口协议(EPP)和FPGA，
RS232
- RS-232、RS-422与RS-485都是串行数据接口标准，最初都是由电子工业协会（EIA）制 订并发布的，RS-232在1962年发布，命名为EIA-232-E，作为工业标准，以保证不同厂家产品 之间的兼容。RS-422由RS-232发展而来，它是为弥补RS-232之不足而提出的。为改进RS-232 通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到10Mb/s， 传输距离延长到4000英尺（速率低于100kb/s时），并允许在一条平衡总线上连接最
