摘要
为了实现远程电能质量监测仪的低功耗、小型化,提出了一种使用带串行接口微功耗A/D的并行多通道采集方案。在介绍了该基于嵌入式采集方案总体设计思想后,具体给出了应用FPGA来实现该带串行接口微功耗A/D转换器的复杂控制逻辑。该逻辑控制中采用了FSM、FIFO等设计模块;最后,运用相应的EDA工具对所设计的A/D时序控制逻辑的正确性进行了仿真验证。所提方案在便携式测试仪器的设计中也具有较高的实用价值。
In order to realize the low power consumption and miniaturization of the remote power quality monitor, a kind of parallel multi channel acquisition scheme using micro power A/D converter with a serial interface is presented. After intro ducing the designing ideas of total acquisition scheme based embedded processor, the implementation of complex logic control for the micro power A/D converter using FPGA is given in detail. The logic control models include FIFO, FSM et al. At last, the correctness of sequential design to control the A/D converter is verified by the simulation experiment with EDA tools. The proposed scheme also has great practical values for the design of portable test instrument.
