A MULTIPLEXER/RECORDER ARCHITECTURE FOR USE WITH CONVENTIONAL MEDIA TECHNOLOGYBerdugo, Albert 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Instrumentation recorders have evolved continuously over the years. Their growth has primarily
been driven by technology advancements. The latest recording equipment generally utilizes hard
disk, disk array, or solid-state storage technology, which results in greater capacity and
performance. Most recorders integrate storage media with multiplexer electronics resulting in a
highly efficient yet inflexible and physically large recording system.
This paper describes an instrumentation multiplexer/recorder system using an open architecture
between the multiplexer and the storage media that allows insertion of conventional recording
technologies. This approach provides a generalized solution with enough flexibility and
scalability to address the majority of instrumentation recording needs. This system is based on
the latest IRIG-106 chapter 10 standard, thus supporting interoperability throughout the flight
test community.

ADVANCED DISTRIBUTED WIDEBAND DATA ACQUISITION SYSTEMBerdugo, Albert 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Wideband data acquisition units have been used as part of an instrumentation system for several decades. Historically, these units operated asynchronously from each other, and from the rest of the instrumentation system when installed on the same test vehicle. When many wideband units are required to slave their formats or sampling rate to the test vehicle’s event of interest such as external computer event clock, radar, or laser pulse train; few solutions were available. Additionally, a single test vehicle may use ten to thirty wideband units operating at up to 20 Mbps each. Such systems present a challenge to the instrumentation engineers to synchronize, transmit safety of flight information, and record. This paper will examine a distributed wideband data acquisition system in which each acquisition unit operates under its own data rate and format, yet remains fully synchronized to an external fixed or variable simultaneous sampling rate to provide total system coherency. The system aggregate rate can be as low as a few Mbps to as high as 1 Gbps. Data acquired from the acquisition units is further multiplexed per IRIG-106 chapter 10 using distributed data multiplexers for recording.

IRIG-106 CHAPTER 10 RECORDER WITH BUILT-IN DATA FILTERING MECHANISMBerdugo, Albert, Natale, Louis 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Sixteen years ago, RCC added Chapter 8 to the IRIG-106 standard for the acquisition of 100% MIL-STD-1553 data from up to eight buses for recording and/or transmission. In the past 5 years, the RCC recording committee added Chapter 10 to the IRIG-106 standard for acquisition of 100% data from PCM, MIL-STD-1553 busses, Video, ARINC-429, Ethernet, IEEE-1394, and others. IRIG-106 Chapter 10 recorder suppliers have further developed customer-specific interfaces to meet additional customer needs. These needs have included unique radar and avionic bus interfaces such as F-16 Fibre Channel, F-35 Fibre Channel, F-22 FOTR, and others. IRIG-106 Chapter 8 and Chapter 10 have provided major challenges to the user community when the acquired avionics bus data included data that must be filtered and never leave the test platform via TM or recording media. The preferred method of filtering data to ensure that it is never recorded or transmitted is to do so at the interface level with the avionic busses. This paper describes the data filtering used on the F-22 Program for the MIL-STD-1553 buses and the FOTR bus as part of the IRIG-106 Chapter 10 Multiplexer/Recorder System. This filtering method blocks selected data at the interface level prior to being transferred over the system bus to the media(s). Additionally, the paper describes the configuration method for defining the data to be blocked and the report generated in order to allow for a second party to verify proper programming of the system.

FIBRE CHANNEL BUS MONITORING WITH AIRBORNE DATA MULTIPLEXER / RECORDER SYSTEMBerdugo, Albert, Pesciotta, Eric 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Modern aircraft now employ widely accepted and standardized technology commonly found in COTS applications. One such technology, Fibre Channel, has been deployed to transport both low and high-speed measurement data. Data as varied as “command and control”, “Radar Sensors” and “video” are being transmitted over fibre channel on many aircrafts. Some of these applications require data monitoring in listening mode only where transmission from the instrumentation equipment is not allowed or possible. As a result, standard off the shelf Fibre Channel devices cannot be used, and a development of a general purpose Fibre Channel monitor/ analyzer device and product is required. This paper discusses the concept, merits, and implementation of fibre channel bus monitoring in modern data acquisition systems. Techniques for tapping into an optical fibre channel network, as well as, a recording format for IRIG106 Chapter 10 are included. An overview of fibre channel topologies and protocols is also provided.

Previous issue date: 2009 / Nas indústrias de processo, os diversos equipamentos formam uma cadeia
contínua, através da qual circulam os fluidos, o meio de ligação entre os mesmo
se dá atarvés de tubulações que são consideradas como equipamentos de
processo. A falta ou paralisação de um único equipamento, sem que tenha sido
programa, pode gerar perdas financeiras em grande escala. Neste ambiente, as
tubulações são responsáveis pela condução dos fluidos, as quais operam em
muitos casos em severas condições de serviço. Na ocasião da montagem, as
tubulações passam por processos de soldagem nos seus diversos métodos de
ligação, durante o processo de soldagem são geradas zonas de aquecimento
localizadas nas juntas onde o material do tubo fica sujeito a variações na sua
microestrutura, o que gera mudanças nas suas propriedades. O processo de
soldagem mais utilizado na soldagem de tubulações nas montagens industriais é
o da soldagem a arco elétrico com eletrodo revestido. Este trabalho apresenta o
resultado do estudo das propriedades mecânicas e estruturais de juntas de tubos
soldadas com arame tubular. Para tanto, utilizou-se tubos confeccionados em aço
ASTM A106 Gr B, recomendado para o transporte de fluidos em alta temperatura,
soldado com o processo de soldagem por arco elétrico com Arame Tubular
Protegido. As soldas de raiz foram feitas com dois diferentes processos: TIG e
Arame Tubular, quando se utilizou arame tubular na raiz, este foi feito com o
mesmo material de enchimento e acabamento. As soldas de enchimento e
acabamento foram feitas com dois tipos de arame tubular, um rutílico e outro
metal cored . Foram realizados ensaios de microdureza e de tração, e análise
microestrutural e macroestrutural das juntas soldadas para verificação das suas
possíveis variações. Os resultados evidenciaram variações nas propriedades das
juntas soldadas quando se realiza a solda nas diferentes amperagens adotadas
neste trabalho, porém mostrou-se possível a utilização do processo estudado em
pequenas juntas de peças que possam vir a serem fabricadas em canteiros de
obra

PCM Telemetry Downlink for IRIG 106 Chapter 10 DataPappas, Johnny, Bagó, Balázs, Cranley, Nikki, Poisson, Gabriel 10 1900 (has links)
ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / Since both airborne and ground applications are able to handle and process IRIG 106, Chapter 10 standard data (further referred to as C10) from files or from live streaming UDP network data, it is a logical extension of the standard to telemeter network data from the air to the ground support systems with little or no modification. This paper describes a method to transport C10 compliant packets over a Class II, telemetry stream (C10 TMDL) which is fully compatible with existing encryptors, transmitters, receivers, and decryptors.

IRIG 106 Chapter 10 vs. iNET Packetization: Data Storage and RetrievalJones, Charles H. 10 1900 (has links)
ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / The approach to recording data during Test & Evaluation has evolved dramatically over the decades. A simple, traditional approach is to pull all data into a PCM format and record that. A common current approach is to record data in an IRIG 106 Chapter 10 compliant format that records different forms of data (bus, discrete, video, etc.) in different channels of the recorder or exported data file. With network telemetry on the horizon, in the form of the integrated Network Enhanced Telemetry (iNET) standards, much of the data will be transported in iNET messages via Ethernet frames. These messages can potentially carry any type of data from any source. How do we record this data? Ultimately, no matter how the data is stored, it must be translated into a form that can be used for data analysis. Data storage forms that are conducive to this analysis are not necessarily the same that are conducive to real time recording. This paper discusses options and tradeoffs of different approaches to incorporating iNET data structures into the existing T&E architecture.

Conversion and Analysis of Telemetric Data from the CCSDS StandardAhlgren, Simon, Aini, Daniel January 2017 (has links)
When communicating with spacecrafts, the international standard is to use the protocols defined by CCSDS. In this study, the Space Packet Protocol from CCSDS is converted to the Digital Recording Standard used in aviation. The goal of the study is to find out in what way such a conversion can be made, as well as analyzing the efficiency of different packing methods for the Digital Recording Standard. An application is developed in order to perform the conversion, and the performance of said application is profiled using different packet sizes. In the end the results are evaluated and an optimal packet size is found in terms of runtime and memory usage. In the end we conclude that a packet size of 216 bytes is best when prioritizing speed, and a packet size of 219 bytes is best when prioritizing memory.
