中文摘要: 提出了一种基于FPGA 的智能化信号调理器的设计方法。该方案根据不同传感器,选择相对应的电流,电压和电荷放大电路对输入信号进行放大,输出到AD7264 采样,经FPGA 滤波等处理。输出方式有两种：直接用以太网接口或CAN 接口输出的数字信号,或者经AD5422 转换成标准的电流电压信号输出。详细描述了硬件部分的设计与实现,给出了电路原理图。在实际运用中,该调理器具有良好的性能和高度的可靠性, 具有广阔的运用前景和推广价值。
Abstract:This paper indroduces the design and realization of a signal transmitter based on FPGA. The sensor signal will be amplified at first, then output to the AD7264. After sampling and processing by FPGA, the data are transmitted by CAN interface or Ethernet interface, or converted into the standard current and voltage output by the AD5422. The article introduces the design and implementation of the system and particularly explains every functional modulethe of the hardware part, detailed schematic diagram and electric circuit's details.
