labview提高例题 更好的掌握和了解编程软件(LabVIEW better examples, better understand and understand programming software)

用LabView制作的一个可乐售卖机小程序。(A small program of Coke vending machine made by LabView.)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

labview 语音信号采集及频谱分析的程序，功能强大好用(labview voice signal acquisition and spectrum analysis)

本人为公司UPS产品编写的电脑监控UPS工作的程序(I am prepared for the company' s computer monitor UPS UPS products work procedures)

Temperature Systems sensor

用labvIEW编写的一个通过ADO对数据库进行添加、删除、更新、连接等操作的通用VI，可以缩短数据库的开发周期(A written in labvIEW of database through ADO connects operations such as add, delete, update, and the general VI, can shorten the development cycle of a database )

labview做的密码登录系统，简单好用(LabVIEW password login system, simple and easy to use)

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)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)
