MXComponent LAbview子VI 直接调用即可

labview论坛-基于虚拟仪器的温湿度监控系统

说明：  可以实现在labview环境下实现FIR滤波器(Labview environment to achieve the FIR filter)

基于labview测正弦信号频率，使用FFT的算法，然后进行波峰检测(Based labview measured frequency)

基于labview的读取并播放声音，对声音进行读取并播放

1、掌握利用A/D转换和计算机资源实现示波器的设计方法。 2、设计虚拟示波器。 3、建立NI-DAQmx仿真设备，选择E系列中的NI PCI-6071E数据采集卡的仿真模块，通过DAQmx物理通道识别，产生模拟信号，然后基于LabVIEW开发平台设计实现虚拟示波器。(1, master the use of A/D conversion and the design method of the computer resources to realize the oscilloscope. 2, the design of virtual oscilloscope. 3, establishment of NI- DAQmx simulation equipment, select the NI PCI- 6071- E E series simulation module of data acquisition card via DAQmx physical channel identification, produce analog signal, and then design the virtual oscilloscope based on LabVIEW development platform.)

可以产生不同调制方式的信号，包括bpsk,qpsk,fsk,msk,16qam,64qam.可以产生不同的样本。(Can generate a signal of different modulation methods, including bpsk, qpsk, fsk, msk, 16qam, 64qam. Can produce different samples.)

编写软件为labview2011，功能为读取txt文件中的值，并绘制电平图，设置了双游标，可以自动准确计算出两游标X轴时间差值。txt的内容为上升沿或下降沿的时间信息，首位0代表下降沿，1代表上升沿。后面位的值乘16代表沿的绝对时间(program software is the labview2011, functions is to read txt file values​ ​ , and draw level diagram, set up a dual cursors, you can automatically and accurately calculate the time difference between the two cursors X axis. txt contents of rising or falling time information, the first 0 represents falling, a representative of the rising edge. Followed by 16-bit value represents absolute time along)

测风流量计算软件程序，主要由labview软件编写，差压式流量计，算法符合伯努利方程，安装后可以直接使用

16进制字符串转十进字符串制显示labview(Hex to decimal conversion)

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.)
