Event Driven IT-OT Architecture Concept- Micro Services to calculate OEE based on incoming MQTT topics
OEE Calculator is a simple API for calculating Overall Equipment Effectiveness (OEE). This project provides an easy way to calculate OEE based on data received from MQTT topics, store the results in an InfluxDB, and serve the calculated OEE values via a RESTful API.
This project implements concepts from the Unified Namespace (UNS), which is a comprehensive structure for organizing data within an industrial context. For more details on UNS, you can refer to HiveMQ's blog on implementing UNS with MQTT and Sparkplug.
- MQTT Integration: Subscribe to MQTT topics to receive real-time data.
- OEE Calculation: Calculate OEE based on received data.
- InfluxDB Integration: Store OEE data in InfluxDB for historical analysis.
- RESTful API: Serve calculated OEE values via a RESTful API.
- Configurable Topics: Flexible configuration for subscribing to different MQTT topics.
To get started with the OEE Calculator, follow these steps:
- Clone the repository:
git clone https://github.com/schmeckm/OEE_calculator.git cd OEE_calculator - Install dependencies:
npm install
3.Configure the environment variables by creating a .env file in the root directory and adding the necessary variables:
