Definitions

  • BACKGROUND 5 The Field of the Invention This invention relates to control systems and, more particularly, to novel systems and methods for integrated monitoring and control of multiple subsystems.
  • KVMs keyboard, video, and mouse switches
  • Display integrators have also been developed. Typically, display integrators combine multiple images, thereby allowing a user to monitor the output of multiple systems from a single display device. However, display integrators neither reduce the number of control input devices nor permit redirection of command inputs. They merely aggregate display images. 0 Currently, personal computers and televisions may monitor and control one or more systems by displaying images from the connected systems and redirecting control from a keyboard and pointer. These devices, however, also have significant limitations. For example, they are limited in their ability to work in real time with multiple diverse systems. Furthermore, they do not allow the user to customize the display image by sizing and positioning the various display elements at will.
  • a method and apparatus are disclosed in one embodiment of the present invention as including a system providing integrated monitoring and control of one or more subsystems.
  • a system providing integrated control may be any arrangement where a user issues commands to, and receives monitoring display information from, multiple subsystems.
  • such a system may include an integrator interfacing between a workstation and multiple subsystems.
  • a subsystem may output a display signal in a particular form (e.g. interface standard).
  • that subsystem may receive commands in a particular form.
  • the display signals and commands of another subsystem may be incompatible with those of the first subsystem.
  • an integrator in accordance with the present invention may function as a translator between a workstation and the otherwise incompatible subsystems.
  • an integrator may translate the display signals, received from the subsystems in various, physically disparate forms, into a common form. Once in a common form, the display signals may be integrated into a composite display signal. The composite display signal may be passed from the integrator to the display of a workstation.
  • an integrator may translate the commands received from the various input devices of a workstation into commands that may be understood by the various subsystems to which the commands are directed.
  • an integrator may include a display processor and a command processor.
  • the display processor may receive the various display signals from the connected subsystems, generate a composite display signal defining various windows, and transmit the composite display signal to the display of the workstation.
  • each incoming display signal may be assigned to at least one window defined by the composite display signal. In other embodiments, only selected incoming display signals or portions of incoming display signals may each be assigned a window.
  • the command processor may direct commands received from one or more input devices of the workstation to their appropriate destinations.
  • Appropriate destinations may include the integrator itself, a neighboring integrator, one or more of the connected subsystems, or the like.
  • a command processor may translate commands before directing them to their destination.
  • a command processor may communicate selected commands, received from a workstation, to the display processor.
  • a command processor may pass a command to the display processor for implementing commands directed to opening, closing, sizing, positioning, or the like.
  • a command processor may provide the mechanism through which a user selects, sizes, positions, or otherwise manipulates the windows presenting real-time visual feedback from multiple subsystems.
  • a command processor may support the saving and recalling of various display layouts comprising arrangements of windows that the user has created and found to be useful.
  • a command processor may be configured to receive, store, and enforce access limitations corresponding to a user.
  • An access limitation may be any restriction on what commands are forwarded by the command processor to the intended destination. For example, in selected situations, it may be desirable to limit which users are able to control selected critical functions of a subsystem. Accordingly, an access limitation may indicate that if a particular user issues a command affecting a critical function of a subsystem 12, that command is to be ignored and not forwarded.

  • Control may be defined in terms of a control loop.
  • a control loop may include two flows of information. Information flowing out may be referred to as a command. Information flowing in may be referred to as feedback.
