OEE Monitoring


Overall Equipment Efficiency (OEE) is a critical performance metric widely employed in production factories to assess the effectiveness of manufacturing processes. OEE provides a comprehensive and holistic evaluation by considering three key factors: Availability, Performance, and Quality.

By combining these factors, OEE offers valuable insights into the overall performance of manufacturing equipment. It serves as a powerful tool for identifying areas of improvement, minimizing downtime, optimizing production speed, and enhancing product quality. Utilizing OEE in production factories enables businesses to streamline operations, maximize resource utilization, and ultimately achieve higher levels of productivity and efficiency.

IIoT Architecture

Industrial Internet of Things (IIoT) refers to the integration of Internet of Things (IoT) technologies and solutions into industrial processes and environments. It involves connecting industrial devices, machinery, and systems to the network to collect, exchange, and analyze data, with the ultimate goal of improving efficiency, productivity, and overall operational performance. 

The following figure illustrates the comprehensive 4-layer architecture of IIoT. Each layer in this well-defined framework plays a crucial role in facilitating seamless integration and efficient functioning of interconnected industrial devices.

The first layer, Perception Layer, encompasses the physical devices and sensors responsible for data acquisition. IIoT relies on sensors and devices that can gather data from the physical world. These sensors may measure parameters like temperature, pressure, humidity, vibration, and more. They act as the eyes and ears of the industrial system.

Moving up the hierarchy, Network Layer manages the secure and reliable transfer of data between devices. IIoT devices are connected to the internet or network, enabling them to transmit data in real-time. This connectivity allows for seamless communication between devices, systems, and centralized platforms. Various communication protocols are used to facilitate data exchange, including MQTT, CoAP, and HTTP, among others. Furthermore, Given the sensitive nature of industrial operations, IIoT implementations prioritize robust cybersecurity measures to protect against unauthorized access, data breaches, and other potential threats.

Finally, Application Layer resides at the top, providing a user-friendly interface for monitoring and controlling industrial processes. IIoT enables predictive maintenance by monitoring the health and performance of industrial equipment. This helps in identifying issues before they lead to equipment failure, reducing downtime. IIoT facilitates real-time tracking of assets, materials, and products in the supply chain, enhancing visibility and efficiency. Process Optimization: By analyzing data from various stages of production, IIoT can optimize manufacturing processes, improve energy efficiency, and reduce waste.

In summary, Industrial IoT transforms traditional industries by introducing connectivity, data analytics, and automation, leading to more efficient, cost-effective, and adaptive industrial processes. It plays a crucial role in the ongoing evolution of smart factories.

Data Gathering

Checking or counting products in production lines involves deploying a combination of hardware and sensors to collect, process, and transmit data. These components play a crucial role in ensuring the efficiency, quality, and safety of manufacturing operations. Some of the hardware commonly used are PLC, sensor, camera, communication networks, HMI and other industrial IoT hardware.

Various sensors may be used in the production lines like proximity sensors, photoelectric sensors, and vision systems as shown in the figure. Proximity sensors detect the presence or absence of an object without physical contact which is used for object detection, presence sensing, and counting items on the production line. Photoelectric sensors use light beams to detect the presence, absence, or distance of objects that are commonly employed for detecting product position, verifying presence, and measuring distances. Vision systems use cameras and image processing to capture and analyze visual data which is useful in product inspection, quality control, and tracking the movement of items on the production line.

Industrial cameras are ruggedized cameras designed for use in harsh industrial environments. They are equipped with features such as high resolution, high-speed imaging, and compatibility with machine vision algorithms. They capture visual data from the production line and are often integrated with machine vision systems for tasks such as quality control, defect detection, and product tracking.
