LabVIEW

用labview实现振动信号采集,用于机械故障诊断，路形检测等(Realize vibration signal acquisition with labview for mechanical fault diagnosis, road shape detection)

主要包含经纬高信息、北天东坐标系、地心坐标系之间的坐标转换，用labview实现的。(It mainly includes the coordinate transformation between the latitude and longitude information, the North East coordinate system and the geocentric coordinate system. It is realized by LabVIEW)

使用EMD对采集数据进行数据模态分解，得到各个分量信号(Use EMD to cEMD data)

labview 实现声音信号的采集并回放 利用生产者消费者模式(labview s sound acquisition and play back using producer-consumer mode)

一个上位机测控软件，采样Labview2011编写，主要功能的和下位机通信，向下位机下发控制指令，并实时显示处理下位机上传的采集数据。(A PC control software, sampling Labview 2011 write, and communicate the main function of the lower down-bit machine control commands issued, and real-time data acquisition display processing lower computer to upload.)

labview报表工具包及实例，方便labview程序及界面的打印、输出报告等。(labview toolkits and examples of statements, convenient interface labview program and print output reports.)

说明：  PCI1020驱动，用于阿尔泰数据采集卡驱动(PCI1020 Driver for Altai Data Acquisition Card Driver)

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)

用于labwindows CVI开发环境 可以完成对串口收发数据十六进制和字符型格式的转换(cvi serial port)
