摘　　要：为了验证遥测系统中被测对象的功能可靠性,研制了一种基于PCI总线的数字量测试台,它用来模拟输出各种测试信号。数字量测试台的实现以FPGA为核心,分别实现了模拟测试信号源的输出和与PCI总线的通信。功能仿真和实际测量验证了设计的可行性。To meet the need of rapid, distant, serial transmission and real-time storage for the received data, develop a multi-channel data acquisition system based on FPGA and UART Interface. Using FPGA we realize data acquisition module ,selecting the channel of Analog Signal and parallel-to-serial converter with Digital Signal, and so on; And using RS-422 Interface realize long distance and serial transmission for Digital Signal. The function simulation results and actual measurement prove the correctness of the design.
