首先，本文运用C语言，自动控制原理等相关知识，使用图形化编辑语言G语言在LABVIEW平台上编写框图形式的PID控制程序，并制作相应的程序前面板，使数字随动系统的控制过程操作更简便，原理更直观；在之后LABVIEW网络通讯功能的设计中，选择利用前面板发布技术这种Z为简单易行的途径实现虚拟仪器的远程发布和控制，又使用了LABVIEW WEB服务中的API密匙来设置远程客户端访问和控制的权限，保证了数字随动系统虚拟仪器远程实验的安全要求。在各部分设计过程的介绍中，还列举了其他很多方法，都将各种可行方案的优缺点进行了评述和对比，并选出Z优的设计方案加以实现。
In this paper， the realization of a LABVIEW-based digital network control system with the experimental development of software in LABVIEW environment control system to prepare digital PID controller with the process， the use of LABVIEW platform features a powerful extension of this set of experimental system on release to the network， and set the appropriate access control and security protection，
First of all， in this article use C language， the principle of automatic control and other related knowledge， the use of graphical language G editing language LABVIEW platform in block diagram form of the preparation of the PID control procedures， and procedures for the production of the corresponding front panel， so that the number of follow-up system to operate the control process simpler and more intuitive principle; LABVIEW after the design of network communication functions， the option of using the front panel that issued the most simple technical way to achieve the virtual instrument and control a remote release and use of LABVIEW WEB services API Micronesia key to set the remote client to access and control authority to ensure that the number of virtual machines with the remote control system of the safety requirements of the experiment. The design process in various parts of the presentation， also cited many other methods， will be the advantages and disadvantages of various options were reviewed and compared， and selected the best design be achieved.
