Data Bus Analyzer

The AVC-cPCI-3008 is an advanced embedded 3U CompactPCI ruggedized PASS Analyzer system for in-flight data monitoring and analysis.

As a major component of high-capacity aircraft data acquisition and processing systems, the rugged analyzer can store data in impact-survivable memory and in removable memory for routine maintenance. The unit functions as a flight-ready 1553 bus data monitoring, collection and analysis system that can easily be fitted into new aircraft or retrofitted inexpensively into older aircraft. This robust data analysis tool provides time-stamped real-time data in engineering form that can be analyzed on-board or downloaded to a notebook-based ground station for immediate analysis.

At the heart of the data analyzer system is data bus analyzer application software. Utilizing an improved operator interface with graphical displays, the software is easy to use and allows intuitive interpretation of flight data. Features include remote control over a network, graphical display for quick data display, real-time engineering unit conversions, and the ability to time-correlate and simultaneously view data from multiple data buses in a single display window.

"With this system, actual data from the avionics systems is recorded in real time. Any event or anomaly can be viewed real-time or later by a flight line technician once the aircraft is on the ground. A technician no longer needs to simulate or try to recreate an in-flight event-he can work with the actual data that occurred in flight. This enables faster and more accurate aircraft diagnostics and system health monitoring," said David Wessing of the Government Group.

"The dual redundant AVC-cPCI-3008 PASS Analyzer system leverages the extensive experience SBS Technologies has with avionic system integration. This conduction-cooled data acquisition system offers avionics designers great versatility and can be customized with other I/O boards to meet a customer's specific needs. The chassis is designed to be mounted in harsh environments where the system may be subjected to higher than normal temperatures and rugged operating conditions," continued Wessing.

The analyzer system uses two conduction-cooled SBS CR3 Intel ULV Celeron processor-based single board computers and two conduction-cooled SBS Sentiris Graphics/Video PMC modules. The system also supports multiple 1553A and 1553B Notice 2 Protocol data streams simultaneously in flight or on the ground and to withstand ncreased temperature, shock, and vibration.
