Conventional data acquisition systems face challenges in achieving high acquisition speeds and rapid storage of large data volumes using microcontrollers. In contrast, field-programmable gate arrays (FPGAs) offer numerous advantages, including high clock frequencies, minimal internal delays, fast operational speeds, abundant internal RAM resources, and simplified control of complex peripheral circuits. This study presents the design of an FPGA-based multimedia remote monitoring system for information technology server rooms. The proposed system utilizes an FPGA as the primary controller and incorporates environmental sensors, electrical energy sensors, carbon monoxide sensors, smoke sensors, and A/D converter modules to monitor multiple locations within the server room. Simultaneously, the FPGA transmits the collected data from each monitoring point via a serial port to an LCD serial screen for display. An alarm is triggered if any environmental anomalies are detected, indicating abnormal statuses. Additionally, the system employs the fast Fourier transform algorithm and butterfly operations to derive voltage and current AC quantities, while utilizing relative temperature differences to identify equipment faults within the server room. The system is evaluated in terms of functionality, user-friendliness, and reliability. Experimental results demonstrate that all performance measures align with expectations, fulfilling the initial design objectives and highlighting the potential applicability and relevance of FPGA technology in the monitoring field. In addition, a comparison between FPGA and traditional microcontroller systems is performed, showcasing the superior processing speed and performance of the FPGA-based system. This comparative analysis further validates the advantages of using FPGA technology in high-speed data acquisition and monitoring applications.

“…5. Approaches for using the digital twin as a reference model and use the deviations to detect unwanted behavior are one natural application of such deviations (Milton et al, 2020;Xiong et al, 2022). However, the objective of the digital twin for safety demonstrations rely on an accurate digital twin.…”

Trust in evidence produced by the digital twin is crucial for critical decision-making. Establishing trust in the evidence produced by the digital twin require a robust qualification and assurance process of the digital twin. A use case of a digital twin for safety demonstrations is used to determine the need for qualification and assurance process throughout the complete lifecycle for the specific application. A battery system consisting of a battery management system and a battery pack is used as a theoretical case study for identifying specific considerations of the use case. Initially the digital twin require a qualification and assurance process that can extend to rare events and often unobserved states, Modeling the behavior in the presence of physical failures and degradation, corrupt data and other communication issues are crucial for demonstrating the capability of the logic to manage and control the battery system from reaching a failed state. During operation different triggers for updating the digital twin to manage changes in the physical space are identified and considerations for handling the updates are presented. Ultimately, the paper offers a recommendation for managing changes in the digital twin proposing a re-qualification and re-assurance process to be based on the change required in the digital twin.

Power generation from wind farms is growing rapidly around the world. In the past decade, wind energy has played an important role in contributing to sustainable development. However, wind turbines are extremely susceptible to component damage under complex environments and over long-term operational cycles, which directly affects their maintenance, reliability, and operating costs. It is crucial to realize efficient early warning of wind turbine failure to avoid equipment breakdown, to prolong the service life of wind turbines, and to maximize the revenue and efficiency of wind power projects. For this purpose, wind turbines are used as the research object. Firstly, this paper outlines the main components and failure mechanisms of wind turbines and analyzes the causes of equipment failure. Secondly, a brief analysis of the cost of wind power projects based on equipment failure is presented. Thirdly, the current key technologies for intelligent operation and maintenance (O&M) in the wind power industry are discussed, and the key research on decision support systems, fault diagnosis models, and life-cycle costs is presented. Finally, current challenges and future development directions are summarized.
