IIoT System Analytics

Moxi sensors detect anomalies, diagnose problems, and prescribe actions for rail, bridge, or electrical grid applications.

An innovative solution for predictive maintenance and beyond

The MOXI™ IIoT System Analytics, a suite of technologies that maximizes systems’ abilities to predict the need for maintenance, repair, or improvement, allows maintenance professionals to act in a timely manner with fully automated prompts.

By improving upon previous reactive maintenance solutions via the integration of AI and IIoT technology, MOXI is able to more accurately predict needs, identify appropriate timing for maintenance to reduce costly down time, and integrate these recommendations into an existing workflow.

This capability surpasses non-automated traditional reactive maintenance practices in which a system, part, or component fails and a maintenance professional performs the necessary repair or replacement. It’s also a step up from preventive maintenance that’s scheduled based on time elapsed rather than on the need for repair or replacement.

MOXI enables the transition to reliable predictive maintenance, thus initiating the digital transformation to truly smart, self-aware systems that yield actionable insights about health, safety and performance.

Expertise in modeling & simulation of cyberphysical systems

Modeling can be done for a variety of purposes, including diagnosis, design, explanation, configuration, and control. These models can be numerical, symbolic, qualitative, teleological, or statistical (e.g., neural nets). For many applications, we use a hybrid approach (a synthesis of symbolic and statistical models).

We use paradigms such as Modelica and MATLAB to construct physical models, and machine learning techniques to construct statistical models. These hybrid models are important because many of the cyber-physical systems we analyze arrive with incomplete models and incomplete data. Only through a combination of both techniques can they be modeled well enough to succeed at the task at hand. Many models can be constructed automatically or semi-automatically, thereby significantly speeding up the system modeling process.

We’ve developed methods for automatically constructing models of faulty behavior from models of nominal behavior through a process we call fault augmentation. These are central to efficient and accurate condition-based maintenance, as in our MOXI™ IIoT System Analytics.

As systems become more complex, technology suites that allow for reliable, predictive condition-based maintenance are more challenging than ever. Schedule-driven maintenance practices can result in expensive and unnecessary inspections early in a system’s life and are insufficient as the system ages and deteriorates. What’s more, the systems supporting traditional maintenance practices have limited accuracy, require extensive training, and often result in too many false alarms. This is where MOXI comes into play.

Applying the principles of physics to enhance AI-based predictive systems to 90%+ accuracy, our diversified, agile, and experienced research & development team will work as a hub between existing technology providers, engineers & facilities, or maintenance teams to develop a fully integrated suite of technology-designed to provide:

Higher Diagnostic and Prognostic Accuracy (90%⁺)
Improved Uptime
Longer System Life
Valuable Insights for Accurate Long-Term Planning
Better Scheduling Accuracy

Through accurate sensing, this technology suite uses AI and IIoT technologies most effectively. By accurately detecting anomalies, diagnosing problem points and prescribing necessary action based on the variables that are critical to system health, our technology suite will streamline operations.

Design Excellence from Start to Finish

Key stages of MOXI IIoT System Analytics technology suite are:

Sensing that’s robust enough to yield accurate system data
Modeling that’s customized and which can simulate adverse conditions and failures the system is designed to prevent
Condition Monitoring that reliably monitors anomalies from expected system behavior
Diagnostics that contain efficient reasoning engines which isolate and infer root causes of faults within sub-systems
Prognostics that use system models and data to probabilistically predict a system’s useful life span
Actionable Recommendations based on decision-theoretic algorithms to promote accurate planning

Our diverse team of researchers collaborate throughout each stage of this process to produce outcomes with the highest accuracy and fewest false alarms, allowing the system to run smoothly and efficiently.

Each piece of the puzzle is critical to success, and MOXI’s team of engineers & researchers address three core elements that inform the process and are essential to producing peak accuracy for each specific system. Explore below to learn more.

The art of sensing

Our team can work with any sensors already installed within a system, assessing them for the metrics they are measuring and assuring that they are accurately detecting the correct information at a high enough level of accuracy.

Our researchers also collaborate closely with the engineers, maintenance staff, or contractors on site to improve or invent them. With expertise in physics-based sensing technology, our team champions connecting the physical and digital worlds. This is how we are able to produce reliable sensing results that are accurate more than 95% of the time, with negligible false alarms and near-zero missed detections.

The science of modeling

Without the correct system model applied to sensing technology, results and recommendations are less likely to hit the mark. Our team will work to make sure sensors are measuring correctly, capturing the data points significant to the desired prediction, and matching them to the right system process identifiers.

By using the suite of technologies to store detailed fault-augmentable models, it is possible to perform rapid diagnoses of system behavior over designated time intervals. Through modeling, we are able to understand the context of any system and produce the recommendations that are important to maintenance repair operations, improving uptime, and transforming the bottom line.

The accuracy of prediction

We have developed a suite of technologies that maximizes systems’ abilities to predict the need for maintenance, repair, or improvement and fully automates prompts that allow maintenance professionals to act promptly. Our system enables the transition to reliable predictive maintenance, thus initiating the digital transformation to self-adaptive assets, which are highly autonomous.

By improving upon these previous solutions via the integration of AI and IIoT technology, MOXI can more accurately predict needs, identify appropriate timing for maintenance to reduce costly downtime, and integrate these recommendations into an existing workflow.
