基于LabVIEW的通用自动测试系统设计

说明：  LABVIEW 写入和读取西门子PLC数据，与西门子PLC通过S7通信读取与写入数据，兼容S7-1200与S7-1500 PLC(LABVIEW Write and Read Data from Simense PLC)

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 )

简单虚拟示波器，能调节幅值，频率，相位和偏移量四种变量。(Simple virtual oscilloscope can adjust four variables: amplitude, frequency, phase and offset.)

labview的PXI应用实例，通过工程实例详细介绍了PXI虚拟仪器的使用。(PXI using in labview)

本系统可做自动控制原理中的时域分析仿真实验，系统特性如下： 1：可选择仿真系统为一阶、二阶、任意阶 2：可选择信号源为正弦波、三角波、锯齿波、方波（可模拟阶跃信号），并可调节信号源频率、幅值、相位、偏移、方波占空比 3：可选择信号采样率及采样数 4：自动计算传递函数 5：自动计算时域响应参数（增益系数、上升时间、峰值、峰值时间、稳定时间、超调量） 6：波形图同时显示原始信号和响应信号 注：使用本系统需安装labview控制设计与仿真库(The system can do automatic control theory in the time-domain analysis simulation, the system behaves as follows: 1: simulation system can be selected for the first, second, any order 2: select the signal source is a sine wave, triangle wave, sawtooth, square wave (analog step signal), and can adjust the signal source frequency, amplitude, phase, offset, duty cycle square wave 3: the the optional signal sampling rate and the number of samples 4: automatic calculation of the transfer function 5: Automatic calculation domain response parameters (gain coefficient, rise time, peak, peak time, settling time, overshoot) 6: waveform diagram shows both the original signal and the response signal Note: Use the system to be installed LabVIEW Control Design and Simulation library)

该文件是labview实现例子，写入和读取二进制文件。(This file is an example of LabVIEW implementation, writing and reading binary files.)

利用VISA去控制GPIB串口通信，最终实现与频谱仪，电源，示波器等相互之间通信(VISA to control GPIB serial communication, and ultimately with the spectrum analyzer, power supplies, oscilloscopes, and other mutual communication between)

说明：  可以将acces数据库中文件导入到excel表格中(updata the data from access to excel)

一个非标项目的架构练习程序，用生产消费的思想和树形结构做的，跟大家分享，里面没有数据部分，只是程序架构，欢迎一起交流labview编程(A non-standard project practice application architecture, made of thought and the tree structure of production, consumption, share with you, there is no data section, just application architecture, welcome to communicate with labview programming)

用LABVIEW实现0度到50度的虚拟温度计(0 degrees to 50 degrees using LABVIEW virtual thermometer)
