涡街流量计数字信号处理系统的改进与实验 本文针对涡街流量计数字信号处理系统存在的不能测量小流量和易受电磁干扰的问题,对其软硬件方面进行了 改进。重新设计和研制了电荷放大器,提高了灵敏度,增强了适配能力。采取了合理的接地和屏蔽措施,提高了系统的抗干 扰能力。采用去均值和频谱校正的方法,改善了系统的测量精度。编制键盘监控软件,采用状态变量法设计键值分析程序, 实现人机对话功能。进行了液体流量和气体流量的标定实验,结果表明,改进后的数字信号处理系统比常规的流量计信号处 理系统的测量精度高、流程比宽和适配能力强。(Vortex Flowmeter digital signal processing system improvements and experimental In this paper, vortex flowmeter digital signal processing systems can not exist in measuring small flows and vulnerable to electromagnetic interference problems, its hardware and software aspects of the Improvement. To re-design and development of the charge amplifier, increasing sensitivity and enhanced adaptive capacity. Adopted a reasonable grounding and shielding measures to improve the system s anti-stem Interference capability. Used to mean and spectral correction methods to improve the system s measurement accuracy. The preparation of keyboard monitoring software, using state-variable method designed to key analytical procedures, Functions to achieve human-machine dialogue. Were liquid flow and gas flow calibration experiments, the results show that the improved digital signal processing systems than the conventional flow meter signal at Management System s high accuracy, process than the w)
