Building Management System with Supervisory Fault Detection Layer

20220035357

2022
A method for detecting faults in a building management system (BMS) is shown. The method includes receiving time series data characterizing an operating performance of one or more BMS devices. The method further includes processing the time series data using multiple different fault detection methods to generate multiple fault detection results. The method includes providing the multiple fault detection results as outputs from the multiple different fault detection methods. The method includes applying the multiple fault detection results as inputs to a neural network that determines whether the multiple fault detection results are indicative of a fault condition in the BMS.

Cross-functional, Multi-organizational STEM Camp Partnership: Teaching Technology and Human-Centered Design in a Project-Based Curriculumre indicative of a fault condition in the BMS.

Summer STEM camps are one of the methods used to introduce middle and high school students to topics and careers in STEM. Frequently, these camps are produced and run by a single academic institution. This paper presents a novel partnership between four different organizations that included a nonprofit community organization, technical university, professional sports team, and major technology company that came together to develop and run a STEM camp for minority middle and high school students. The STEM camp content was split between design and technical topics and was designed to meet the individual goals of each member of the partnership. This paper describes the camp development and activities, the relationships and interactions between the partnering organizations, and presents key takeaways from multiple years of running the camp.

A Review of Electronic Engineering Logbooks Throughout the Electrical En-gineering Curriculum

Holland, S.S., Bonniwell, J.L., Carl, J.D.

2018

Successful engineers must be well versed in communication skills, particularly with respect to written documentation in engineering logbooks. Such logs provide technical records that facilitate the day-to-day work of individual engineers, as well as enable continuity when projects are transferred to other engineers. Due to changes in technology and patent law, as well as the promise of simple archiving and sharing of technical work, many practicing engineers have moved away from traditional bound paper engineering notebooks and have embraced electronic documentation methods. This work details the experiences of junior electrical engineering faculty members implementing electronic engineering logbooks in their courses at the Milwaukee School of Engineering. While the current literature contains some discussion of electronic logbook usage in single courses, this paper takes a broader view by reviewing the use of electronic logbooks in courses that span all aspects of the electrical engineering undergraduate curriculum, from freshman to senior year. With this diverse set of courses, the lab assignments range from prescriptive step-by-step procedures to openended design projects. Each faculty member has been teaching for less than six years and joined academia with several years of industry experience. This work shares their experiences and observations on the advantages and disadvantages of electronic notebooks learned through implementation in their courses. Though this paper is primarily focused on electronic notebook usage in the electrical engineering program, the general observations are applicable to a broad range of engineering disciplines.

An Approach to Parallel Simulation of Ordinary Differential Equations

Carl, J.D. and Biswas, G.

2016

Cyber-physical systems (CPS) represent a class of complex engineered systems where functionality and behavior emerge through the interaction between the computational and physical domains. Simulation provides design engineers with quick and accurate feedback on the behaviors generated by their designs. However, as systems become more complex, simulating their behaviors becomes computation all complex. But, most modern simulation environments still execute on a single thread, which does not take advantage of the processing power available on modern multi-core CPUs. This paper investigates methods to partition and simulate differential equation-based models of cyber-physical systems using multiple threads on multi-core CPUs that can share data across threads. We describe model partitioning methods using fixed step and variable step numerical integration methods that consider the multi-layer cache structure of these CPUs to avoid simulation performance degradation due to cache conflicts. We study the effectiveness of each parallel simulation algorithm by calculating the relative speedup compared to a serial simulation applied to a series of large electric circuit models. We also develop a series of guidelines for maximizing performance when developing parallel simulation software intended for use on multi-core CPUs.
