动态链接库

In the paper chapter one introduces the background and significance about designing the GPIB controller based on Ethernet. Chapter two describes the whole design idea of the controller, at the same time, introduces ENET protocol, TCP/IP protocol and other associating protocols. Chapter three discusses the hardware and firmware design of ENET-GPIB controller. Chapter four describes how to realize the dynamic link library functions and VISA functions of the controller. Chapter five collogues the trend of ATS. Chapter six summaries the design and give some experience and advice about scientific research.

本文第一章讨论了设计基于ENET 总线的GPIB 控制器背景意义，第二章大致描述控制器的整体设计框架，并简要介绍ENET，TCP/IP 等相关协议；第三章阐述了ENET-GPIB 控制器的硬件电路及底层固件的设计与实现；第四章阐述ENET-GPIB 控制器动态链接库函数和VISA 控制函数的实现；第五章畅谈自动测试系统的发展趋势；第六章对整个ENET-GPIB 控制器设计进行总结，并给出了个人的科研心得体会。

Information Print genie is based on the software works VbPrint another dynamic link library components (VbP rint.dll) in the secondary development of software products, VbPrint developed by the author is a dll ActiveX components, components provide a simple method handling and processing of all types of statements, the statements can be defined linear, rectangular, Yuan, text, images and other objects, and can be connected to the development of programming control these objects in nature, support forms printing, multi-page printing, chromatography printing information such as invoices.

资料打印精灵是基于我的另一个软件作品VbPrint动态链接库组件(VbPrint.dll)的二次开发软件产品，VbPrint是作者开发的一个ActiveX dll组件，组件中提供了一种简单的方法处理和加工各种类型的报表，在报表中可以定义直线、矩形、圆、文本、图像等对象，并可以在二次开发编程中控制这些对象的属性，支持表格打印、多页打印、资料发票套打等。

Controlling-program calls some functions from DDL, and outputs high-level to the digital output channels of the card which are connected with two switches. When the state of switches changes, the phase of the frequency converter' output-voltage changes.

控制程序调用动态链接库函数给采集卡的数字输出通道置位，通过控制两个继电器的通断来控制变频器的输出电压相位，达到控制试验机的加载电机转向的目的。
