可以实现Labview与基恩士激光位移传感器实时数据获取(Real-time data acquisition of Labview and Kean laser displacement sensors)

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.)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)

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：  基于LabVIEW数据库的操作教程，内含全面的ADO对数据库的全面操作，简单易懂。(Database reference tutorial)

根据当前热敏电阻阻值，求出当前温度值。(According to thermistor resistance, find its current temperature. Just enter the thermistor resistance can be run.)

通过设定扫频范围及采样信息，产生一个chrip 信号。(generate a chirp signal, this vi could be used as a signal generation for free.)

用LabVIEW实现对输入音频滤波达到降噪效果(LabVIEW filter of audio signal)

用LabVIEW编写，从excel中读取数据到labview中，将labview数据存储到excel中 这个比较简单了，直接利用写入电子表格文件VI。(Write in LabVIEW, read data from Excel to LabVIEW, store LabVIEW data into Excel This is a simple way to write directly to the spreadsheet file VI.)

信号发生器，带扫频，带频率的切换！最小可以0.1HZ。(Frequency sweep signal generator, belt, belt frequency switch! Minimum to 0.1 HZ.)
