电机控制器的串口通信界面,基于labview visa,德马克电机(Serial communication interface of motor controller based on LabVIEW visa, demarcation motor)

几个练习使用Labview编程的产物，主要包括：1.正弦扫频信号发生器，可选择频率变化规律（不变、线性、指数变化）以及幅度变化规律（不变、线性、指数变化），还可以通过MathScript节点自定义频率、幅度变化规律； 2.声卡数据采集及频谱分析；3.会说话的小圆点；4.十六进制数布尔数组显示；5.在字符串中显示多种字体；6.钢琴键盘模拟(Several products by practicing Labview programming, including: 1 Sine sweep signal generator, selectable frequency variation (constant, linear, exponential change) and amplitude variation (constant, linear, exponential changes), you can also customize the frequency and amplitude variation through MathScript Node 2 sound card data acquisition and spectrum analysis 3 talking dots 4 hexadecimal to boolean array display 5 display a variety of fonts in the string 6. Piano keyboard simulation )

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

使用labview实现波形包络检波，可以当子VI使用(Using LabVIEW to realize waveform envelope detection can be used as sub-VI)

对LabVIEW进行二次开发，对振动信号进行HHT时频分析(The LabVIEW was developed two times, and the vibration signals were analyzed by HHT time frequency)

说明：  Labview使用OPC和其他PLC通讯配置方法步骤。(LabVIEW uses OPC and other PLC communication configuration method steps.)

用LabVIEW实现小波阈值降噪程序，很有用的~，呵呵~(use LabVIEW wavelet thresholding procedure noise, very useful-and Ha ha ~)

虚拟万用表，4060模拟，采用labview编写(Virtual multimeter, 4060 Analog, labview write)

基于研华PCI-1710数据采集卡的多通道高数数据采集(Multi channel high data acquisition Advantech data acquisition card based on PCI-1710)

基于LabVIEW软件编写，利用Hilbert变换实现回声信号的检测。(Hilbert transform echo signal detection)
