1	Energy Monitoring System for Security and Energy Management Applications Shariati, Sepideh 16 January 2013 (has links) This thesis presents an energy monitoring system to measure energy consumption of software applications to support security and power management for embedded devices. The proposed system is composed of an Actel Fusion device and a custom designed energy measurement circuit. The Fusion device measures the voltage and the current of the target device at a defined sampling rate. The energy measurement circuit is designed as a current integrator over fixed intervals using the switched-capacitor integrator technique to store energy information of the target device within Fusion’s sampling intervals. This circuit is designed to accommodate the low sampling rate of the Fusion device. Experimental results showed that the Fusion device allows the measurement of the energy of the target device at a minimum rate of 15 µs. The energy measurement circuit is implemented using the 65 nm CMOS technology. Simulation results showed that this circuit provides 91%~97% average energy measurement accuracy.
2	Redesign and Improve an Energy Monitoring System with the Open Sandbox Experience through Simplification and Limitation / Omarbetning och förbättring av ett energiuppföljningssystem med open sandbox-struktur genom förenkling och begränsning Huang, Hsuan-Li January 2022 (has links) Energy monitoring systems (EMS) are crucial in improving energy eciency to encourage sustainable development. Such systems usually come with an open sandbox experience to provide multiple tools for monitoring, analytic, and reporting purposes, but this also creates user experience (UX) issues. EMS and energy dashboards have been well researched from a technical perspective while simplification and limitation are also thoroughly studied within HumanComputer Interaction (HCI). However, few have applied the HCI literature to the EMS field, especially in solving the UX issues that the open sandbox experience creates. Therefore, this study aims to bridge this gap and study how to improve an EMS with an open sandbox experience through simplification and limitation. In what follows, the discovery and definition of UXissues in the system through pre-study, interview study, and user evaluation are presented. A prototype was also developed with the help of HCI literature to solve these issues, and was evaluated with the participants. The results show improvements in participants’ task performance and the proposed redesign received positive feedback. In the discussion, key considerations for the design of EMS systems are raised, as well as the sustainability eects of this study and possible future directions. / Energiuppföljningssystem (EMS) är avgörande för att förbättra energieektivitet och på så vis bidra till en hållbar omställning av samhället. Sådana system har ofta en öppen design för att tillhandahålla en stor bredd av analysverktyg, men detta skapar också problem med användarupplevelsen. EMS har i literaturen undersökts väl ur ett tekniskt perspektiv, och designprinciper så som förenkling och begränsning har också studerats grundligt inom området för människadatorinteraktion. Dock finns det få studier som har använt dessa principer för att förbättra energiuppföljningssystem i synnerhet, särskilt för att lösa användbarhets-problem som en öppen design skapar. Därför syftar denna studie till att undersöka detta genom att omarbeta och förbättra ett EMS med en öppen design lösning med hjälp av designprinciperna förenkling och begränsning. Genom en förstudie, en intervjustudie samt en användarutvärdering har användbarhesproblem identifierats i systemet. En prototyp togs också fram med stöd i litteraturen för att lösa dessa problem, och den utvärderades senare med deltagarna. Resultaten visar en förbättring i deltagarnas uppgiftsutförande och den förbättrade designen fick positiv feedback. I diskussionen beskrivs ett antal insikter relevant för design av energiuppföljningssystem, samt diskuterar olika hållbarhetsaspekter vid denna studie och framtida ämnen att utforska. user experience user interface design evaluation energy monitoring system energy dashboard användarupplevelse användargränssnitt design utvärdering energiuppföljningssystem energi-dashboard Computer and Information Sciences Data- och informationsvetenskap
3	PLANT LEVEL IIOT BASED ENERGY MANAGEMENT FRAMEWORK Liya Elizabeth Koshy (14700307) 31 May 2023 (has links) <p><strong>The Energy Monitoring Framework</strong>, designed and developed by IAC, IUPUI, aims to provide a cloud-based solution that combines business analytics with sensors for real-time energy management at the plant level using wireless sensor network technology.</p> <p>The project provides a platform where users can analyze the functioning of a plant using sensor data. The data would also help users to explore the energy usage trends and identify any energy leaks due to malfunctions or other environmental factors in their plant. Additionally, the users could check the machinery status in their plant and have the capability to control the equipment remotely.</p> <p>The main objectives of the project include the following:</p> <ul> <li>Set up a wireless network using sensors and smart implants with a base station/ controller.</li> <li>Deploy and connect the smart implants and sensors with the equipment in the plant that needs to be analyzed or controlled to improve their energy efficiency.</li> <li>Set up a generalized interface to collect and process the sensor data values and store the data in a database.</li> <li>Design and develop a generic database compatible with various companies irrespective of the type and size.</li> <li> Design and develop a web application with a generalized structure. Hence the database can be deployed at multiple companies with minimum customization. The web app should provide the users with a platform to interact with the data to analyze the sensor data and initiate commands to control the equipment.</li> </ul> <p>The General Structure of the project constitutes the following components:</p> <ul> <li>A wireless sensor network with a base station.</li> <li>An Edge PC, that interfaces with the sensor network to collect the sensor data and sends it out to the cloud server. The system also interfaces with the sensor network to send out command signals to control the switches/ actuators.</li> <li>A cloud that hosts a database and an API to collect and store information.</li> <li>A web application hosted in the cloud to provide an interactive platform for users to analyze the data.</li> </ul> <p>The project was demonstrated in:</p> <ul> <li>Lecture Hall (https://iac-lecture-hall.engr.iupui.edu/LectureHallFlask/).</li> <li>Test Bed (https://iac-testbed.engr.iupui.edu/testbedflask/).</li> <li>A company in Indiana.</li> </ul> <p>The above examples used sensors such as current sensors, temperature sensors, carbon dioxide sensors, and pressure sensors to set up the sensor network. The equipment was controlled using compactable switch nodes with the chosen sensor network protocol. The energy consumption details of each piece of equipment were measured over a few days. The data was validated, and the system worked as expected and helped the user to monitor, analyze and control the connected equipment remotely.</p> <p><br></p> Electronic sensors Systems engineering Database systems Information extraction and fusion Information retrieval and web search Query processing and optimisation Stream and sensor data Cloud computing Networking and communications Knowledge and information management Software architecture Data structures and algorithms IIoT architectures IIoT IIOT SENSOR APPLICATIONS software architecting generic application design Energy Monitoring Z- Wave OpenHAB Real time Energy Monitoring System Sensors and actuators Wireless Sensor Network (WSN) web server Web Application Generic web application Database design Generic database Architecture edge computing based Industrial Application edge computing strategy Python Flask Framework API sensor interfaces cloud storage data interactively remote Control
