软件定时

所写的Labview程序可一次性计算出轴承的故障特征频率，方便实用(Written Labview program can calculate a one-time fault characteristic frequency of the bearing, convenient and practical)

晶体的真空调频设备控制VI，通过串口于西门子PLC的通信。实现现场测量参数返回、控制命令下达、动作参数下达PLC、显示测量结果。(I edit the vacuum device control program, the programming language is LABVIEW, thanks to the example of network gods. Upload this document, hoping to provide help for later generations.)

说明：  串口的接收和发送，labview编程，学习visa的配置，写入，读取，关闭等功能(test the serial ports programming)

说明：  labview采用DAQ采集数据进行采集。(LabVIEW uses DAQ to collect data.)

产生0到100kd的方波。正玄波，三角波，锯齿波和输出为0到10V的电压的信号发生器(0 to 100kd produce a square wave. Sine wave, triangle wave, sawtooth wave and the output voltage from 0 to 10V signal generator)

Labview的小波分解与还原程序，没有调用matlab，配套论文，可以此为基础改成小波去噪程序(Labview wavelet decomposition and reduction program, there is no call matlab, supporting the thesis, this can be changed based on wavelet denoising procedure)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

上位机服务器程序，可以动态监听连接上来的设备，与客户端通讯，发数据。(The upper computer server program can dynamically monitor the connected devices, communicate with the client and send data)

说明：  抽取不同声音（适应文件）的统计特征、信号处理参数（模式），设计简单的基于适应特征的声音识别程序。(Extract the statistical features and signal processing parameters (patterns) of different sounds (adaptive files), and design a simple voice recognition program based on adaptive features.)

介绍了Labview编程中的堆栈技术，提供demo案例。(This paper introduces the stack technology in Labview programming and provides demo cases.)
