Abstract

Typically, prior to initiating the production of a piece of equipment, it is necessary to model the performance of certain subsystems within the equipment using one or more fixtures designed to perform in accordance with the subsystem requirements. It is during the development of such a fixture, including the fixture controller, that the controls engineer must generally work with the fixture engineer to understand the fixture control requirements. The comrnon interface used by both engineers is generally a fixture timing diagram, which shows the sequence of events that must occur for the fixture to operate properly. Unfortunately, completion of the timing diagram is usually a very tedious task, and frequently requires numerous revisions.

GRAPHICAL TIMING INTERFACE FOR FIXTURE CONTROLLER

(Cont'd)

Typically, prior to initiating the production of a piece of equipment, it is necessary to model the performance of certain subsystems within the equipment using one or more fixtures designed to perform in accordance with the subsystem requirements. It is during the development of such a fixture, including the fixture controller, that the controls engineer must generally work with the fixture engineer to understand the fixture control requirements. The comrnon interface used by both engineers is generally a fixture timing diagram, which shows the sequence of events that must occur for the fixture to operate properly. Unfortunately, completion of the timing diagram is usually a very tedious task, and frequently requires numerous revisions.

Accordingly, the present invention proposes a tool which would be used by both the controls engineer and the fixture engineer to automate and ease the interface between the two. The tool, a graphical timing interface, consists of a Timing Diagram Generator and a Graphics Screen Compiler. The Timing Diagram Generator is a user-friendly computer interface which would allow the fixture engineer to generate a set of controls requirements by representing the operation of the fixture in a timing diagram format, similar to that shown in the figure. In addition, the timing diagram created on the Timing Diagram Generator will include supplemental information such as cause and effect relationships betwe...
