A test control board with FPGA as the core control device, coupled with multi-channel analog signal acquisition and output channel, and multi-channel digital signal input and output channels, which have RS-232 and RS-422 serial communication function are designed in this paper. In the Quartus 117.2 programming platform, the hardware description language program of data collection, processing, control and communications are designed. After some tests, it met technical requirements of the two-dimensional platform system, which have good stability and scalability.%设计了一种以FPGA作为中心控制器件,配以多路模拟信号采集与输出通道和多路数字信号输入输出通道,具有RS-232和RS-422串口通信功能的测试控制板卡.在Quartus Ⅱ7.2编程平台下,编辑了数据采集、处理和控制以及通信的硬件描述语言程序.经应用测试,满足二维平台系统的技术要求,具有良好的稳定性和可升级性.
