基于labview的FIR数字滤波器设计(Design of FIR Digital Filter Based on LabVIEW)

说明：  Keller压力传感器labview源程序(Keller pressure sensor LabVIEW source program)

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)

说明：  Scripts for up sampling and down sampling

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

利用Matlab的图象处理功能对摄象头采集到的仪表图象进行分析,得到指示值,同时利用dll 技术,在虚拟仪器编程软件Labview 中调用,输出得到对应的计算值,实现了对指针式仪表的自动监控,增加了整个系统的稳定性和可靠性。(Using Matlab image processing functions on the image pickup head collected instrument image analysis, to give the instruction value, while using dll technology, called the virtual instrument programming software LabVIEW, obtained from the output corresponding to the calculated value, the pointer Instrumentation automatic monitoring, increasing the stability and reliability of the whole system.)

说明：  基于labview的modbus通讯范例(Modbus communication paradigm based on LabVIEW)

labview应变信号采集储存显示。采用Dll连接设备，采集信号，有采集储存显示调零及回放功能。(labview strain signal acquisition and store display. Using the the Dll connection equipment, signal acquisition, collection storage to zero and playback capabilities.)

解决LabVIEW里不能使用数码管字体的方法 用FontCreator软件打开字体，将字体的平台由“Windows Unicode BMP(UCS-2)”改为“Windows Symbol”即可。(Method for solving LabVIEW can not use digital tube font With FontCreator software to open the font, the font platform Unicode BMP Windows (UCS-2) to Symbol Windows can be.)

华氏度转换为摄氏度，代码短小，可靠性高，转化方便，适合做课后练习(Convert Fahrenheit to Celsius, the code short, high reliability, easy transformation, suitable for after-school practice)
