如何解决NT网远程引导中的疑难问题

所谓远程引导即工作站启动无需硬盘,而是先启动远程引导服务器。工作站启动或引导一台计算机时,计算机操作系统便装入内存。ＷＩＮＤＯＷＳＮＴ远程引导服务支持对运行ＭＳ－ＤＯＳ、ＷＩＮＤＯＷＳ３．１和ＷＩＮＤＯＷＳ９５的工作站的远程引导。这些工作站使用服务器...     

Novell网无盘工作站远程引导文件的建立方法

随着信息需求量在日常生活中的迅速增加，计算机网络已在各个领域显示出巨大作用，许多单位在实现计算机网络管理的同时，大都选用无盘工作站以节省资金。而在Novell网上，由于光盘工作站无处存放开机启动必需的系统文件，只能借助于服务器实行远程启动（RemoteBoot）。这就要求网络管理人员必须学会制作无盘工作站的远程引导映象文件。无盘工作站的启动原理在无盘工作站的网卡上必须插有一块远程复位芯片（PROM），里面含有固化的引导程序。在启动过程中，此芯片会联系服务器以实行远程启动。在服务器硬盘上必须存放有该站的远程启动映…

Executive workstations: Issues and requirements

An executive workstation is an integrated hardware/ software system that can provide business executives with powerful capabilities for making and implementing decisions. In this paper, relevant and sometimes controversial, issues and workstation requirements are discussed in the context of a scenario that portrays an executive using a workstation. The scenario anticipates fifth generation computer technology and it guides a specification of features and functions. The goal is to clarify what is possible and desirable in an executive workstation design.

Advancements of the KUCIM automated flexible manufacturing workstation

Incremental automation, i.e. adding capabilities over time, is an alternative for small mannfacturers to large scale automation projects as a method of achieving automated manufacturing. As an example of incremental automation, the University of Kansas Computer Integrated Manufacturing (KUCIM) workstation has developed over time into an unmanned flexible machining workstation. Presently, the workstation contains a Hurco three-axis milling machine, an American Robot six-axis robot, a Sun 4/260, a versatile fixturing system, an IBM PC-AT compatible computer, and an interface between the milling machine and PC. The control architecture is based on the National Institute for Standards and Technology (NIST) Automated Manufacturing Research Facility (AMRF) manufacturing control hierarchy. The workstation controller employs three software modules: the Supervisor, the Robot Foreman, and the Fixture/Machine Tool Foreman. At the equipment level, two modules are used: the Robot Command Interpreter and the Fixture/Machine Tool Command Interpreter. The three functions that the KUCIM workstation performs to produce parts are: processing an input file, performing tool zeroing and performing machining cycles.

Computed radiography and image workstation from the radiologist's point of view.

A computed radiography system (Digiscan, Siemens) connected to an image workstation (Siemens) has been used for 1 1/2 years in our department. The image quality is good and it has been possible to reduce radiation dose by about 30% without any appreciable loss of image quality. The image workstation has been used in cases where image postprocessing is considered to be useful. For routine reporting of X-ray images the workstation is too slow although the image quality is comparable to that of the computed radiography film.

Visual display unit workstation lighting

Two experiments determined preferred general and workstation illumination; workstation illumination was 350 lux. In experiment 1, 12 subjects were treated to 2 illumination sources, 6 task lighting conditions and 3 screen luminance conditions. Subjects preferred the indirect + direct illumination. Preferred task document brightness ranged from 190 to 890 nits. There were no screen character brightness differences. In experiment 2, 24 subjects were treated with a constant workstation illumination of 350 lux to 6 conditions (2 illuminations of the room wall and 3 illumination levels in the area ahead of the operator). In the area ahead of the operator, subjects preferred an illumination (770–820 lux) level doubling the workstation illumination over 420 and 1180 lux. Subjects also preferred increased brightness variability on the wall.

For offices with VDUs, designers should not only plan for a mixture of indirect + direct lighting but also should consider the lighting of the workstation surroundings as well as the workstation.     

Management scheme of a workstation controller in a flexible manufacturing system

A workstation controller is an industrial computer which controls the function of the unit workstation in a flexible manufacturing system. A workstation is considered a functionally cohesive group of machine equipment and the operation is carried out independently. The basic operating unit in a workstation controller is the computer program. In other words it is a task. A set of software tools has been defined, developed, and tested for a workstation controller. The tasks create a workstation domain which makes the user application that controls and monitors the workstation operation. A specific program called Configuration Manager, consisting of various modules, is responsible for supervising the tasks within a workstation controller. Usually, a single Configuration Manager resides in a workstation controller. However, multiple Configuration Managers can be utilized in several CPU boards in a common backplane. The program has been developed on a realtime operating system to fit into the realtime environment of a manufacturing system. The Configuration Manager is written in the “C” programming language to enhance the portability. However, the user application software could be written in any higher level language.
