Frequency-Hopping-test

Determine the tone of a given signal.

关于列车故障诊断振动信号分析研究系统的开发(Fault Diagnosis of train vibration signal analysis system development)

LABVIEW 数据采集，和电机控制，通过板卡可以控制电机的转速，并且能采集电机的转速信号。程序比较简单，不是采用DAQ编写。(LABVIEW data acquisition, and motor control board can be controlled via the motor speed, and can collect the motor speed signal. Procedure is relatively simple, instead of using DAQ write.)

说明：  使用.ini文件的用户登陆，跳转，有用户管理功能，可添加，删除帐号，修改密码，修改帐户类型，帐户管理界面点击右键弹出菜单。(Users who use the. INI file log in, jump, and have user management functions. You can add, delete accounts, modify passwords, modify account types, and right-click the account management interface to pop up the menu.)

labview旋转机械轴心轨迹的子程序。(labview Frequency division amplitude)

说明：  labview编写串口通讯实例，基于ModBus协议，使用串口通讯，与电机驱动器通讯，实现信号写入与读取，从而控制电机(LabVIEW serial communication, signal writing and reading)

高端大方的多行列表控件，机场标牌效果，非常漂亮(High-end generous multi-line list controls, airport signage effect, very nice)

In this program we put any temperature and the program will show us with booleans if there is a problem about the temperature

在LABVIEW开发平台下，结合测试与信号处理理论设计下述虚拟仪器： 1 函数发生器； 2 频谱分析仪； 3 消噪演示仪； 4 串口通信演示仪。(Under the LABVIEW development platform, combining the test and signal processing theory, the following virtual instruments are designed. 1 function generator; 2 spectrum analyzer; 3 de-noising demonstrator; 4 serial communication demonstration instrument.)
