SES Solid State Data Recorder - Compact Extended

The S3DR product family is a low cost, high performance, rugged solution to the processing and data recording needs of environmentally challenging embedded system, such as those found in aerospace, defence, naval and safety-related or high performance industrial applications.

The S3DR product family is designed with flexibility and expandability in mind. S3DR-CE (Compact Extended) is a specialisation of the more generic product family providing communications, data acquisition and data recording functions where space and mass are at a premium. The unit features a high-speed solid state memory recording function, that is able to write data to memory media from multiple monitored interfaces at combined speeds of up to 60 Mbits (7.5 Mbytes) per second.

The S3DR-CE supports either PCMCIA style high capacity solid state cartridges (with max storage capacity 16GByte).

The S3DR-CE is extremely configurable through the presence of an onboard embedded computer and flexible FPGA, allowing application specific data gathering regimes and various I/O options to be accommodated, the S3DR-CE is also designed for serious expansion allowing multiple data acquisition and communications options, which can either be configured in a distributed or integrated architecture.

The S3DR-CE can be used as a data recorder or for data uploading applications.

Typical applications of S3DR-CE include use as a mission recorder, flight test recorder, Quick Access Recorder, engine test data acquisition unit or incident investigation recorder. Typical configurations can be specified focussing on Audio, Video, Data bus, Ethernet or Vibration monitoring.

SES Solid State Data Recorder - Compact Extended: Interfaces

S3DR-CE is built around a highly distributed data acquisition and recording architecture, utilising a high-speed deterministic data communication bus, the S3DR-CE product can be configured as multiple remote data acquisition and communication modules that provide data to a single recording function.

The recording function is built from the SES miniature S3DR-C recorder, the smallest high speed recorder in the world. The recording, communications and data acquisition architecture supports system implementations that are built from single self-contained miniature units, or multiple distributed nodes connected to a central recording and control function.

Total recording bandwidth on the data bus is 60Mbit/s which can be made up of data from a selection of core interfaces and additional optional interfaces. The core interface functions include those available on the S3DR-C recorder, and these are:

• 4x RS422/485/232 Rx, 1x RS422/232 Tx/Rx
• 2x CAN bus (MilCAN Capable)
• IRIG B Timecode Input
• 4x Arinc429 Rx
• 4x 10-bit A/D converter (voice or other analogue input at up to 625KSPS)
• 8x Discrete I/O (TTL) or 4x Opto-isolated I/O
• 2x IRIG106 PCM (high speed serial - up to 40Mbit/sec)
• 2x Ethernet 10/100

One of the following optional interfaces can also be selected:

• 1x, 2x or 4x Dual Redundant 1553B (BM/RT/BC functions or multi-function)
• 8 Channel Arinc 429 Rx/Tx
• 8 Channel Audio/Mic
• 2 Channel MPEG2 Encoder with 4 Channel Audio

Alternatively, the S3DR-CE can be configured to record 16 channels of A/D at 14-bit with signal conditioning, such as strain gauge and thermocouple inputs, as well as core interfaces.

SES Solid State Data Recorder - Compact Extended: Memory

The S3DR-CE platform offers several data recording media systems, including:

• Solid State Removable Memory Module
  
  
  
  
  SES Solid State Removable Memory ModuleS3DR-CE utilises high speed, high capacity PCMCIA ATA flash, providing low-cost high-performance removable media, with the added advantage that they can be read using a standard laptop, or a special high-speed reader.
  
  SES have qualified a number of extended performance PCMCIA ATA flash cards which can be used with S3DR-CE, but the recommended solution is to use SES own design of solid state removable memory modules. These have extended environmental performance and functionality, which when used in conjunction with an SES recorder, provide optimal performance.
  
  SES solid state removable modules are available in the following capacities 256MB, 512MB, 1GB, 2GB, 4GB, 6GB, 8GB and 16GB. All SES cartridges are environmentally enhanced to achieve exceptional environmental performance:
  • Performance:
    • Data Transfer Rates: Sustained read/write rate: 60 MBits per second (min)

SES Multi-Channel Video and Data Recorder: Support

SES provide a number of optional support items to maximise the potential of the S3DR-MVDR platform, including:

• REVEAL

REVEAL is a partner product to the S3DR-MVDR data recorder. It allows the user to extract and manipulate data from a removable memory cartridge and prepare the cartridge for reuse by the S3DR-MVDR. REVEAL is an application for Microsoft Windows that provides a wealth of features for extracting, interpreting, visualising and analysing data captured using an SES data recorder. Key features of the tool include:

• Convert data to a variety of formats to allow analysis with domain specific tools
• Interpret data to demultiplex or decommutate a data stream into its constituent parameters
• Archive data to hard disk, CD or DVD for later analysis or long term storage
• Visualisation of data to allow visual analysis within REVEAL using a framework that supports real-time and fast-time playback where suitable hardware is available
• Declassification of S3DR data storage media
• Annotation of recorded data with supplementary data, for example Form 725

The architecture of the application allows for easy customisation of the application to suit bespoke requirements, for example introduction of a new component to output data in a new format. Alternatively, the underlying components can be reused to provide a bespoke application to automate the extraction and processing of S3DR data cartridges.
