Real-time Crepper Motor Monitoring System Problem Statement: In a large-scale rubber processing plant, the “Crepper Machines” are the heart of production. The client, Sri Trang Agro-Industry PCL, needed to monitor the electrical current (Amps) of 3 critical motors in real-time. Previously, operators had to manually check readings from local panel meters, making it impossible to analyze historical trends or detect anomalies (like motor overload) instantly. The Challenge: Legacy Connectivity: The existing meters were standard Digital Meters (Primus TCM-94N-AB) communicating via Modbus RTU over RS-485, requiring a reliable bridge to the IT network. Data Integrity: The system needed to handle potential connection drops and ensure data continuity for accurate reporting. User Accessibility: The dashboard had to be accessible via a web browser on the local network without complex software installation on client machines. Our Solution: Hybrid IoT Gateway WP Solution architected a Web-based Monitoring System that bridges the gap between the factory floor and the control room. We utilized Node-RED as a robust middleware to poll data from the meters and Vue.js for a high-performance frontend dashboard. ...

Rubber Compounding & Precision Weighing Control System Problem Statement: In the Master Batch (MB) and Carbon Master Batch (CMB) production lines of a leading automotive rubber manufacturer, manual chemical weighing processes were prone to human error. Deviations from the specific rubber formula resulted in quality issues, waste, and a lack of digital traceability. The Challenge: Precision Requirement: The system must interface directly with high-precision scales to ensure chemical weights fall within strict tolerance levels. Network Instability: Production cannot stop even if the factory network/server goes down. Inventory Control: Need real-time stock deduction and validation to prevent incorrect material usage (wrong lot/wrong type). Our Solution: Smart Weighing & Interlock System We developed a robust Windows Forms Application (C# .NET) that acts as the “Process Controller” for the mixing line. The system integrates IT and OT layers to enforce strict process control. ...
