Technical Operating Report on the Data Integration and Collection Environment(DICE) Instrumentation System Design

摘要

Current and planned avionics radar systems are highly sophisticated in theircapabilities and heavily dependent on Embedded Computer Systems (ECS) for their operation. Avionics radar systems containing ECS provide a high level of flexibility in both system configuration and capability. However, increased flexibility requires increased logistical support. This support includes both hardware and software maintenance. Air Force Logistics Command (AFLC) is conducting a concentrated effort to limit the rising cost of ECS support while responding to user requests for improving these systems. This effort and the ECS Support Improvement Program (ESIP), a program implemented to address the problem of developing a rapid turnaround capability for airborne avionics radar systems, have as one of their research and development objectives to develop the necessary rapid turnaround capabilities to support mission critical ECS. Rapid Turnaround (RT) is defined as correcting a system deficiency in a timely fashion through some combination of software, firmware, and/or hardware modifications. The RT concept evolved from the overall AFLC objective to decrease the time and resources required to implement operational or maintenance changes in deployed ECS. Avionics systems are designed with internal data buses which can provide access to vast amounts of data. The data buses contain data, such as MIL-STD-1 553 and H009 and are located primarily in the programmable signal processor. The need for an instrumentation system hosted on-board a tactical aircraft resulted in the development of the Data Integration and Collection Environment (DICE) System by TRW and the Air Force.
