基于DSP与FPGA的科里奥利质量流量计(CMF)可以直接测量流体的质量,针对当前流量计设计复杂,精度较低,升级维护灵活性较差。采用FPGA高速采集数据,DSP进行算法处理,提高实时响应速度与抗干扰能力。数据采集与处理的模块化设计进一步提高了系统稳定度和维护便易度。实验结果表明,本文所设计的基于DSP与FPGA质量流量计较以往类似的质量流量计测量精度有很大提高,测量单元、数据采集、数据处理的模块化设计使得系统稳定度增加。
Coriolis mass flowmeters (CMFs) based on DSPs and FPGAs allow direct measurement of fluid quality, complex designs for current flow meters, low accuracy, and poor upgrade and maintenance flexibility. High-speed FPGA data acquisition, DSP algorithm processing, improve real-time response speed and anti-interference ability. The modular design of data acquisition and processing further improves system stability and ease of maintenance. Experimental results show that the accuracy of the mass flowmeter based on DSP and FPGA designed in this paper has been greatly improved compared with that of the conventional mass flowmeter. The modular design of the measurement unit, data acquisition and data processing makes the system more stable.
