DMX 512协议是Digital Multiplex的缩写，是灯光行业数字化设备的通用信号控制协议，同时也是是一种国际协议。 　　USITT DMX512/1990是调光和灯光控制台数据传输标准，是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多，现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年，在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)

说明：  说明：此为球形开关测试程序的上位机软件。 能够记录由下位机上传的每支球形开关 的通断情况，自动记录上传的时间， 并且会将历次的结果保存在PC机的硬盘 中，带有具体的日期，方便查询。(Note : This spherical switch to the testing procedures PC software. To record the next crew uploaded each spherical switch-off, automatically records upload time, and will keep all the previous results of the PC's hard disk, with the specific date, and easily accessible.)

说明：  GpRS数据中心代码，基本上实现了数据中心的大部分功能(GpRS data center code, basically realize the majority of the data center functions)

这是一个云台控制的软件，我只是实现了上下左右，自动几个功能，为了测试用，不过可以调通。(This is a PTZ control software, I just realized vertical and horizontal, automatic several functions, in order to test, but can be transferred through.)

VB6.0与变频器的RS485或Modbus通讯，控制变频器的参数设定，运行状态，运行频率，读当前状态，电流，电压，频率，故障等。支持远距离控制。(VB6.0 and drive the RS485 or Modbus communications, control the inverter parameter settings, operation status, operating frequency, read the current state, current, voltage, frequency, fault and so on. Support remote control.)

说明：  利用动态链接库现LabVIEW与USB设备的数据通信(Is the use of dynamic-link library of LabVIEW and the USB data communication equipment)

VC++和 Matlab 的 混 合 编 程 具 有 很 大 的 实际意义。 文 讨 论 了如何 使 用 Matlab 的 Complier 将 *.m 函 数 编 译 为 动 态 链 接 库 DLL， 提 供 给 VC++调 用 的 方 法，提 供 了 一 种 VC++与 Matlab 混合编程的 快 速 实 现 。(The mixed programming of VC++ and Matlab has great practical significance. This paper discusses how to use COMplier of MATLAB to compile *. m function into DLL of dynamic link library and provide a method for calling VC++. It also provides a fast realization of mixed programming between VC++ and MATLAB.)
