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)

用GAL16V8设计可变长度序列信号发生器，在掌握伪随机序列性质的基础上，设计给定长度的伪随机序列信号发生器，也即设计给定n后（n为移位寄存器的级数）最长线性反馈移位寄存器序列。并在给定n产生的最长序列的基础上，截短出课题给出的序列长度，并用FM软件对可编程器件GAL16V8进行编程，以实现长度不同的序列信号发生器。(GAL16V8 design variable-length sequence signal generator based on the master pseudo-random sequence nature, the design of a given length pseudo-random sequence
Signal generator, designed for the series) up to linear feedback shift register sequences given n (n is the shift register. And given n
Sequence length given by the subject on the basis of the longest sequence, truncated, and FM software for programming the programmable device GAL16V8, in order to achieve
Different length of the sequence signal generator.)

HART通用压力变送器的设计压力变送器采用的传感器通常需要不同电路与之配合使用，这就造成产品种类较多，不宜量产。一种崭新的设计思想，设计出的新型电路可以提供软件可控的恒压、恒流输出给传感器，并可以采集两路差分或四路单端输入信号。(HART universal pressure transmitter pressure transmitter used in the design of sensors usually used in conjunction with the different circuits, which result in more product categories, not mass production. A brand new design ideas, to design a new circuit can provide software controlled constant voltage, constant current output to the sensor and can capture two-way differential or four single-ended input signals.)
