MODULAR EDGE SYSTEM FOR DATA COLLECTION AND ANALYSIS BASED ON RASPBERRY PI AND SOC FPGA

Abstract

Article presents a modular telemetry platform for real-time collecting, processing, and presenting data that is relying on edge computing principles. The architecture integrates sensors as data producers, controllers (Raspberry PI and SoC) for processing data, and a web interface used to present and operate that data, into a unified architecture with less reliance on external networks. This method lets the platform function without reliance on global network therefore it can do it job in environments that have no reliable network coverage. Local data transfer is built around usage of MQTT broker, making sure that messages are sent and received, while keeping whole process asynchronous. All the parts function together in a localized Wi-Fi network, which makes it possible for data to be shared without needing additional transport laters. This setup does away with the requirement for cloud servers while still keeping data safe and making sure the system can keep running. SQLite, when set to write-ahead logging mode, is a strong way to save data locally and lets you quickly get back to work after an unforeseen error. The visualization layer, which is built on the Leaflet library, allows real-time map rendering and dynamic data updates through Server-Sent Events (SSE). This gives operators a clear, constantly updated view of the system's state. Connecting SoC FPGA modules and other devices through UART and SPI interfaces makes it possible to sync data at the hardware level and opens up new ways to scale the system. The architecture described provides a simple, modular, standalone solution. It meets the specifications for modern industrial IoT, so it can be used for research, field deployment, or laboratory automation. It is possible to easily add more sensors, data processing units, or communication interfaces to the system. Also, the whole approach allows possible extension to actually work with global network and distant compute power if needed in centralized structure arises. This makes it a flexible base for future development while keeping its essential functions and stability.
