Abstract

Penelitian ini merancang sistem pemantauan angular velocity berbasis sensor gyroscope yang terintegrasi dengan media transmisi kabel fiber optik sepanjang 150 km menggunakan topologi ring. Sistem ini bertujuan untuk menyediakan solusi pemantauan data orientasi dan pergerakan sudut secara real-time dengan tingkat keandalan yang tinggi, khususnya di wilayah dengan risiko gangguan elektromagnetik. Data hasil pengukuran sensor dikirimkan melalui jaringan kabel fiber optik menggunakan perangkat industrial Ethernet switch dan modul SFP, kemudian divisualisasikan dalam dashboard berbasis C#. Hasil implementasi menunjukkan bahwa sistem mampu mentransmisikan data tiga sumbu (X, Y, dan Z) secara stabil tanpa degradasi sinyal yang signifikan, serta memberikan notifikasi anomali secara langsung. Sistem ini berpotensi diterapkan pada aplikasi pemantauan struktur bawah laut dan sistem peringatan dini tsunami. 

Review

The manuscript presents a design and implementation of an angular velocity monitoring system that leverages a 150 km fiber optic transmission medium with a ring topology. This research addresses a critical need for reliable, real-time orientation and angular movement data, particularly in environments susceptible to electromagnetic interference, such as subsea structures or early tsunami warning systems. The proposed system's long-distance capability and inherent immunity to EMI, facilitated by fiber optics, represent a significant contribution towards robust remote sensing solutions. The technical approach outlined involves integrating gyroscope sensors with an industrial Ethernet network, utilizing SFP modules for data transmission over the extensive fiber optic cable. The data is then visualized via a C#-based dashboard, indicating a comprehensive end-to-end solution. The abstract highlights successful implementation, demonstrating stable transmission of three-axis data without significant signal degradation and the provision of direct anomaly notifications. This practical demonstration of reliable data conveyance over a considerable distance using a resilient ring topology underscores the system's potential for real-world deployment in challenging environments. While the abstract provides a compelling overview, a more detailed quantitative analysis of the system's performance would strengthen its claims. For instance, specific metrics regarding latency, data throughput, or the exact threshold for "significant degradation" would be beneficial for a complete assessment. Furthermore, elaborating on the mechanisms for anomaly detection and the types of anomalies the system can identify would enhance clarity. Future work could explore the system's scalability, its performance under varying environmental stressors beyond EMI (e.g., temperature, physical stress on the cable), and a comparative analysis against alternative long-distance monitoring approaches to fully benchmark its advantages. Nevertheless, the presented work offers a promising foundation for highly reliable remote angular velocity monitoring.
