【摘要】：随着计算机技术的飞速发展,计算机技术和电子测量技术的结合形成了自动测试系统,使得电子测量技术产生了质的飞跃。自动测试系统在测试速度、效率、精度、可靠性以及测试数据的可交换性等方面较传统的电子测量仪器更具优势。虚拟电子测量仪器集成系统是吉林大学自己研制的一套自动测试系统,采用模块化的设计理念,将各种电子测量仪器集成为可以实现对应测量功能的模块板卡,然后通过自定义的总线技术连接在一起,组建成为一个可以实现各种电子测量功能的测试工具。本文主要工作是虚拟电子测量仪器集成系统基础架构的研究与设计。第一,研究现有的各种总线技术,提炼出一种适合本系统的总线技术;第二,设计系统控制器和各个模块化仪器之间的通信协议;第三,设计USB2.0系统控制器用来实现上位机和模块化仪器之间的数据通信,USB2.0系统控制器的设计包括硬件电路设计和固件程序开发;第四,系统驱动程序开发,系统驱动程序是上位机与系统控制器之间通信的“桥梁”,USB驱动程序内封装了有关USB接口操作的函数,上位机LabVIEW通过调用DLL中的函数访问USB通用驱动程序,实现对USB接口的操作。最后,通过系统测试验证了本文所设计的虚拟电子测量仪器集成系统基础架构能够实现上位机软件与模块化仪器之间的通信,达到设计目标。
[Abstract]:With the rapid development of computer technology, the combination of computer technology and electronic measurement technology has formed an automatic test system, which has made a qualitative leap in electronic measurement technology.The automatic test system has more advantages than the traditional electronic measuring instruments in the aspects of test speed, efficiency, precision, reliability and the exchangeability of test data.Virtual electronic measuring instrument integration system is a set of automatic test system developed by Jilin University. With the modular design concept, various electronic measuring instruments can be integrated into a module card that can realize the corresponding measurement function.Then it is connected by custom bus technology to form a testing tool which can realize various electronic measurement functions.The main work of this paper is the research and design of the integrated system infrastructure of virtual electronic measuring instruments.First, study the existing bus technology, extract a bus technology suitable for the system; second, design the communication protocol between the system controller and various modular instruments; third,The design of USB2.0 system controller is used to realize the data communication between host computer and modularized instrument. The design of USB2.0 system controller includes hardware circuit design and firmware program development.The system driver is the "bridge" of communication between the host computer and the system controller, which encapsulates the function of the USB interface operation. The upper computer LabVIEW accesses the USB universal driver by calling the function in the DLL.Implement the operation of USB interface.Finally, the system test proves that the integrated system infrastructure of virtual electronic measurement instrument designed in this paper can realize the communication between the host computer software and the modular instrument, and achieve the design goal.
