Sistema Acquisizione Dati Modbus Locale

@iglobalvn

Ciao, posso realizzare un sistema di acquisizione dati Modbus completamente on-premise, basato su Node-RED + PostgreSQL, con dashboard web in tempo reale, pensato per essere chiaro, estendibile e stabile nel tempo. Ho esperienza con Modbus (TCP/RTU), Node-RED, PostgreSQL e dashboard di monitoraggio energetico, e capisco bene il requisito chiave: zero cloud, tutto locale. Approccio proposto: • Node-RED per: • polling dei sensori Modbus • normalizzazione dei dati • scrittura su PostgreSQL • struttura modulare per aggiungere nuovi sensori facilmente • PostgreSQL con schema pulito: timestamp, sensore, unità, valore • Dashboard web (Node-RED Dashboard o frontend open-source) con: • grafici interattivi (line/area/bar) • filtro per intervallo temporale • export CSV Deliverable: • Flussi Node-RED pronti all’import • Script DDL PostgreSQL • Codice sorgente della dashboard + istruzioni di deploy • Guida step-by-step per installazione su Linux Il risultato sarà un prototipo funzionante, pronto a crescere senza refactoring pesanti, con codice commentato e documentazione essenziale. Per favore inviami un messaggio privato così possiamo discutere nel dettaglio sensori Modbus, frequenze di polling, ambiente target e tempistiche. Un saluto,

As a seasoned Full-Stack Developer with over 7 years in the industry, I am well-equipped to take on your project. My extensive knowledge and expertise in various technologies like Node.js, PostgreSQL, and SQL make me an ideal candidate for building and optimizing your Modbus data acquisition system. Additionally, my familiarity with Node-RED will ensure a clean, well-structured data model that allows easy integration of new sensors in the future - ensuring your project scales seamlessly. My experience with Data Management and Visualization come in handy here as well. I have a deep understanding of how to process large amounts of data efficiently and present them intuitively through interactive charts - a key requirement mentioned in your job description. Moreover, I can export data in the desired CSV format with timestamped entries for different sensors and units of measurement. Lastly, I appreciate the importance you place on clean code and essential documentation; it aligns perfectly with my development philosophy. I assure you that not only will you receive top-quality deliverables - ready-to-import Node-RED flows, PostgreSQL schema script, dashboard source code, and step-by-step installation guide but also clear comments throughout the codebase. Trust me with your project and let's build an efficient & solid Modbus data acquisition system together!

Hello, I can develop a fully local data acquisition system using Node-RED to handle Modbus sensor polling, data normalization, and forwarding to a PostgreSQL database. I'll ensure a clean data model, including timestamp, sensor ID, unit, and value, allowing for easy future sensor additions. For visualization, I'll create interactive charts (line, bar, or area) with time-filtering and CSV export capabilities, hosted on either Node-RED Dashboard or a small Express server. Deliverables will include: • Ready-to-import Node-RED flows. • PostgreSQL schema scripts. • Source code for the dashboard with build/deploy instructions. • A step-by-step installation guide for Linux. I prioritize clear, well-documented code to support future scalability. Could you specify if you have any preferred front-end libraries, or should I choose one? Also, do you have a specific timeline for the project's completion? Looking forward to discussing how we can make this prototype both robust and scalable. Thanks and best regards, Faizan

Posso creare un sistema completamente locale in Node-RED che legge sensori Modbus, registra i dati su PostgreSQL e li mostra in una dashboard web interattiva con grafici in tempo reale, filtri per intervallo e esportazione CSV. Consegnerò flussi pronti all’import, script per il database, codice della dashboard e guida chiara per l’installazione su Linux.

❤️ Ciao, Ho realizzato sistemi on-premise per acquisizione dati industriali usando Node-RED come orchestratore: polling Modbus TCP/RTU, normalizzazione dei payload e persistenza in PostgreSQL con schema time-series (timestamp, sensor_id, unità, valore) pensato per scalare e aggiungere sensori senza toccare la logica core. In quei progetti ho costruito dashboard web locali con grafici interattivi in tempo reale, filtri per range temporali ed export CSV, usando Node-RED Dashboard o un layer Express leggero con librerie open-source, ottenendo visualizzazioni chiare, basse latenze e manutenzione semplice. Lo stesso approccio ti consegna un prototipo pulito, commentato e pronto a crescere. Best Regards, Oscar

Hi, I can do this. I will develop a fully local system to read Modbus sensors, log power and energy consumption in PostgreSQL, and present the data through a real-time web dashboard using Node-RED. The solution will include: - Node-RED flows for sensor polling and data normalization. - A clean PostgreSQL schema with timestamp, sensor ID, unit of measure, and value. - An interactive dashboard with line/bar/area charts, time filtering, and CSV export functionality, hosted on Node-RED Dashboard or a small Express server. Deliverables will include import-ready Node-RED flows, PostgreSQL schema scripts, source code for the dashboard with build instructions, and a step-by-step installation guide for Linux. I estimate the project will take approximately 3-4 weeks to complete, ensuring clear, well-documented code for future scalability. I look forward to your response. Ashnasajid

Salve, nodered ha già un flow configurato? Che soluzione preferisce webapp o app ad hoc per il sistema target ?
