Labview Date Calculator

通过labview编写的简易计算器，可实现加减乘除等大部分运算功能(A simple calculator written by LabVIEW can realize most of the operation functions such as addition, subtraction, multiplication and division.)

labview实现单边傅里叶变换，很好的将时域信号变为频域信号(Labview unilateral Fourier transform，Good time domain signal into frequency domain signal )

西门子S7-1200 PLC支持多种协议通过以太网通讯方式，如OPC、TCP、S7、MODBUS-TCP等。TCP方式相比其它协议，具有更多的灵活性，更快的数据响应等优点，本人即介绍LabVIEW通过TCP方式与S7-1200 PLC通信。 S7-1200 PLC的TCP通信方式，称之为“开放式用户通讯”，通过以太网发送或读取数据。(SIEMENS S7-1200 PLC supports a variety of protocols through Ethernet communications such as OPC, TCP, S7, MODBUS-TCP, and so on. Compared with other protocols, TCP has more flexibility, faster data response and so on. I introduce LabVIEW to communicate with S7-1200 PLC through TCP mode. S7-1200 PLC TCP communication, known as "open user communications", send or read data over ethernet.)

修改后的LABVIEW小波（调用MATLAB）(LABVIEW modified wavelet (call MATLAB))

说明：  labview FX-3U modbus通信(labview FX-3U communication)

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)

.用产生三种不同波形，分别计算并显示它们的单边频谱及功率谱，显示低通、带通、带阻、高通四种不同的滤波效果，体会滤波器的使用。(Three different waveforms are produced, and their single side spectrum and power spectrum are calculated and displayed respectively, which show four different filtering effects, such as low pass, bandpass, band resistance and high pass, and realize the use of the filter.)

用于振动信号的采集，LABVIEW程序，用于齿轮箱等机械设备的振动故障诊断。(For vibration signal acquisition, LABVIEW program for vibration fault diagnosis of gearboxes and other mechanical equipment.)

LabVIEW心电检测系统，主要是滤波 信号采集 频谱分析 显示波形等(LabVIEW ECG detection system is mainly filtered signal acquisition spectrum analysis shows waveforms)
