LabVIEW里实现服务器功能，后面还有客户机(server)

LabVIEW平台开发的振动测试程序，可实现时域分析，频域分析，频响分析等功能(LabVIEW platform for the development of vibration testing procedures, time-domain analysis, frequency domain analysis, frequency response analysis functions)

虚拟万用表，4060模拟，采用labview编写(Virtual multimeter, 4060 Analog, labview write)

创建一个vi，实现对按钮状态的指示和按钮“按下”持续时间的简单计算功能，按下按钮时，对应的指示灯亮，对应的数字量显示控件中开始计时。松开按钮时，指示灯灭，计时停止。(Create a VI to realize the instructions of the button state and the simple computing function of the button "press" the duration. When the button is pressed, the corresponding indicator lights up, and the corresponding digital quantity displays the timing in the control. When the button is loosened, the light is put out and the timing is stopped.)

LABVIEW数据库连接，可以作为一个模板进行使用(LABVIEW database connection)

LABVIEW初学练习，定点数转换，了解VI的创建，保存以及前面板和程序框图(LABVIEW Initial Practice, Fixed Point Conversion, Understanding VI Creation, Preservation and Front Panel and Program Block Diagram)

机械振动信号的自相关分析，对其进行周期成分检测(Autocorrelation analysis of mechanical vibration signals to detect its periodic components)

主要是labview在串口通讯过程中，采用modbus-crc 16 位校验方法(LabVIEW is mainly used in the serial communication process, using modbus-crc 16 bit calibration method.)

说明：  labview控制步进电机实现恒速运动控制(LabVIEW control step motor to realize constant speed control)

测试电源的三相电压，包括幅值、频率、相位等信息。(3 pulse voltage test)
