Combatant Craft Health Monitoring System
AREA(S): Battlespace, Electronics, Sensors
PROGRAM: PMS 325G, Support Ships, Boats and Craft
Develop and implement a system that includes real-time recording, monitoring
and data analytics, diagnostic, and prognostic capabilities for manned craft
extensible to unmanned vessels.
This topic seeks to develop an innovative solution for a craft data
acquisition, processing, and display system capable of simultaneously receiving
inputs in various data formats from relevant onboard sources as well as sensors
from other applicable development projects for processing and/or storage on
removable or uploadable media for future analysis. The Health Monitoring
System (HMS) at a minimum must have recording, diagnostic, and prognostic system
capability in order to identify maintenance/repair issues as well as provide
post-mission forensic analysis and playback of maintenance and operational data
in order to understand all aspects of the craft and human environment during
the course of a mission. The HMS should provide a mechanism to assist in
identifying root cause of minor, significant and catastrophic craft, systems,
and component failures. Characterization of group-wide maintenance and repair
issues will provide potentially significant savings by forecasting system
degradation especially in critical operating environments that could have
devastating results in loss of assets or personnel.
The HMS should have diagnostic and prognostic capabilities in order to identify
system issues and predict future failure modes. The HMS should have the
ability to assist in identifying means to improve operations for reduced cost,
identify areas for reduced maintenance intervals, target maintenance actions,
predict imminent failures, and offer means for root cause analysis of failures
while providing insight into total craft mission performance. Data analytics
is a key component of the system and a primary area for innovation to adapt or
field new algorithms and techniques to meet the objectives listed. The HMS
should also provide a real-time display for guiding a craft operator towards
reduced fuel consumption, optimized energy consumption, and cue attention to
imminent system faults. Post-mission, the HMS should also assist a craft
operator in rapidly understanding the environmental severity of a mission and
cueing to any particular anomalies.
Capabilities should include secure electronic transfer (Wi-Fi or Radio
Frequency (RF) data link and interface cable) and physical transfer (removable
storage media) of craft data to a dedicated shore station. The shore station
post processing and “digital dashboard” is a critical feature that will provide
the human interface for the desired situational awareness, required actions and
trends to monitor. The shore station should allow an operator to view any part
of a mission and key filtered data. The shore station should also allow an
operator to display, recreate, playback, and/or print mission critical craft
system parameters (engine, gearbox, fluid systems, power, etc.) and operating
environment to include, at a minimum, craft motions and high shock events with
a virtual craft mimicking motions encountered. Mission playback should include
location on digital nautical charts and overlay Automatic Radar Plotting Aids
(ARPA) and Automatic Identification System (AIS) contacts as well as provide a
histogram laid format over a human and craft performance limit trend lines.
The HMS should record all data with Global Positioning System (GPS) and time
stamp information, as well as provide video Electro-Optical/ Infrared (EO/IR)
data and communications recording and playback. GPS data capture should have
the capability to be disabled. System shall have ability to turn off,
physically disable GPS tracking without negatively effecting system
performance, and shift graphical user interface to provide new user environment
without blank screens or data fields. Shore station shall provide provisions
to organize multiple craft data sets and transmit data over the internet to
server for fleet-wide analysis and trending from a central location. System
architecture should be flexible enough to add real time capability at a later
date and underway data transfer link over satellite radio or Line of Sight
radio to promote the extensibility to unmanned craft Command and Control (C2)
The final HMS should be packaged in a relatively small footprint, meet marine
standards, and be hardened in order to survive a catastrophic craft event. The
HMS should also be capable of being easily mounted inside craft with military
specification connections. The weight of the controller should not exceed 20
pounds. The power connection should accept between 10 and 28 volts DC. The
HMS’s internal components should be suitable for the environment specifications
and not include unique custom components unavailable without long lead times.
Mechanical drives should not be used for the final design.
The HMS should not require custom firmware or operating system. The software
should have diagnostic features such as a system heartbeat that is remotely
available or broadcasted. All software should be capable of successfully
running on a standard Navy Marine Corp Internet (NMCI) laptop.
The shore-side part of the HMS should be a commercially available laptop that
does not require special components or software and be similar to a standard
NMCI laptop in performance/capabilities.
The typical environmental requirements for equipment on the craft are as
Moisture: 99% humidity, condensing.
Temperature, Ambient: -40 to 154 degrees Fahrenheit.
Shock: 10g vertical/100msec half sine pulse, 5g lateral/100msec half sine
Vibration: Capable of surviving and remaining fully operable in accordance with
MIL-STD-810G Method 514.6 in the presence of random vibration defined by the
vertical power spectral density (PSD) curve of Figure 514.6C3, one hour in each
Repeated Operational Wave Slam: Equipment shall be able to perform its normal
functions during and following exposure to 1.5g, 100 msec half-sine pulses, 800
pulses at 1.0 second intervals.
Corrosion Control: All fasteners shall be corrosion resistant steel, conforming
to UNS S31600. Exterior surfaces and connectors shall be able to withstand
testing in accordance with MIL-STD-810G Method 509.5 for salt fog environments.
Electromagnetic Interference: International Electrotechnical Commission (IEC)
I: Develop a concept for a Combatant Craft Health Monitoring System. No
hardware is expected to be designed or prototyped. The contractor at this
point should be very specific in the design approach, data acquisition system
design, shore station design, and software design. Define the proposed
algorithms for a HMS. Craft shock processing algorithms for development of
histogram will be provided by the Government. The Phase I Option, if awarded,
will include the initial design specifications and capabilities description to
build a prototype HMS in Phase II. Develop a Phase II plan.
II: Based on the results of Phase I and the Phase II Statement of Work (SOW),
develop and deliver a full-scale prototype to the Navy for evaluation. The
prototyped onboard and shore-side hardware with beta phase of software should
be operational. The prototyped hardware should be a seaworthy, hardened system.
III DUAL USE APPLICATIONS: Support the Navy in transitioning the technology for
Navy use. The fully hardened HMS for sea trials should be demonstrated
successfully on a manned or unmanned vessel. The HMS should pass an underway
test plan to be developed for the defined test platform.
Marine, air, and land vehicle electronics industries will benefit from this
HMS. This type of system can be applied to any vehicle to provide diagnostic
and prognostic system capability in order to identify maintenance/repair
issues, provide performance analysis and playback, and assist in identifying
root cause of catastrophic or significant and minor vehicle, systems, and
