数据采集编程指南 上篇

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)

2182表的库文件，版本较早，可以用于早期设备使用。(The library file for 2182 instrument)

（2） 发生一个值为0.0~10.0之间的随机数，并除以一个在前面板中输入的数。如果输入的数为0，则点亮LED，提示除数为0时，除法无效。((2) a value of 0.0 to 5.0 occurred between random numbers and dividing by a number entered in the front panel. If the input is 0, then lit LED, prompted the divisor is 0, the division is invalid.)

说明：  使用labview进行设计，里面内含粉尘采集，气压采集，温度采集，适度采集等子程序及其集合(Design with LabVIEW, which contains dust collection, air pressure collection, temperature collection, moderate collection and other subroutines and their collection)

labview 数据保存，到指定的路径，结构清晰，明了(LabVIEW data preservation)

利用DAQ助手实现的基于LABVIEW的示波器，可通过数据采集卡实现各种波形显示和尺度调节(DAQ assistant to achieve the use of LABVIEW based oscilloscope, through the data acquisition card to achieve a variety of waveform display and scale adjustment)

说明：  Labview虚拟示波器程序，编程入门提高(LabVIEW virtual oscilloscope program, programming to improve the entry)

关于labview的一些程序，用于了解机器视觉的(Some programs about LabVIEW)

labview串口程序，可发一个四字节有符号数，多字节可自己修改，使用文本框，数组和示波器输出。(sent a signed int eger whit 4 Byte)

本vi用于从串口读取十六进制数据并保存数据至tdms文件。用户可在第二个循环中根据自己的串口数据格式进行改动。 （需要安装visa驱动）(This VI is used to read sixteen hexadecimal data from the serial port, and save data to the TDMS file.)
