This section of the Ruggedized Camera Encoder (RCE) wiki
documents the process that was followed in designing the
RCE system. Here is presented the systems analysis,
architecture, and the engineering process.
This section is devoted to the research of
technologies relevant to the RCE system design.
Nine products, similar to the RCE were analyzed on 25
different metrics. From this analysis it was concluded
that the final RCE system would need to meet several
technical requirements to be considered competitive
against the other comparable technologies:
Cost Effectivity: Based upon the
products that were evaluated, the maximum and minimum
price points were approximately $1,300.00, and $900.00,
respectively. However, data on this metric was
limited--there were only two products that provided
Ruggedization: Systems in this space
must meet shock, and waterproofing requirements. The
important shock standards under consideration are
EN50155, NEMA TS 2, and MIL-STD-810; the important
waterproofing standard is IP67. The final system should
withstand between 10% and 95% humidity. Aluminum alloy
casing is preferred to enhance heat dissipation.
Network Connectivity: The majority of
systems, to enable modularity, are designed to
integrate high-speed ethernet.
Storage Capacity: The RCE system must
be capable of storing data from the high-speed input
stream(s). Furthermore, the ability to upgrade the
storage is desirable.
Compactness: The enclosure must be
reasonably sized to compare with the dimensions of the
competing technologies. From the analysis of the 8
products, the average of the weight of the components
was 4.155 lbs; the dimensions of the comparable
products are presented in a bar chart below.
I/O Availability: The system should
have GigE compatibility, UART, and HDMI for the sake of
flexibility. Furthermore, coaxial cabling should be
used for the input(s). The system should process input
at Gigabit speeds and process video data with sub 100ms
Real-time Processing Capability : The
RCE system should utilize a processor that is capable
of managing the input data-rate, with minimal loss of
Robust Power Compatibility: The system
should operate across a wide range of voltages and low
power consumption. For the comparable techonlogies, the
maximum and minimum power consumption values were 22W
and 7.5W, respectively.
Comparable Systems Trade Analysis
This section provides an in depth benchmark
analysis of other devices with a similar feature set to the
RCE system. Nine different products were evaluated on 25
different metrics. From this benchmarking process, several
design decisions were made. The data used for the analysis
are provided in the following document. Furthermore, the
analysis is provided in the Subsystem Design Review
document in the System Overview section.
