In sectors like mining, oil & gas, and transportation, workers are equipped with RFID tags and wearable sensors to oversee their location, heart rate, skin temperature, and additional data. This sensor data is scrutinized in conjunction with contextual data sourced from environmental sensors, task planning systems, weather updates, and more, aiming to discern anomalous behavioral patterns and avert accidents. For instance, if a worker’s skin temperature and heart rate escalate without movement for approximately a minute, it might signal overheating. An IoT solution can alert the worker’s supervisor or physician via a mobile application in such instances.

IoT Applications in Industrial Asset Management

The Internet of Things (IoT) is harnessed to heighten the efficacy of manufacturing operations, guarantee appropriate asset utilization, elongate equipment service life, augment reliability, and deliver optimal asset returns. Several IoT applications facilitate industrial asset management, encompassing industrial asset tracking, inventory management, and predictive maintenance grounded in condition monitoring.

Industrial Asset Tracking

Zebra’s 2017 Manufacturing Vision Study prophesies that smart asset tracking solutions grounded in RFID and IoT will eclipse conventional spreadsheet-based methodologies by 2022. IoT-driven asset management solutions furnish accurate, real-time data about an enterprise’s assets, encompassing their statuses, locations, and movements. This obviates up to 18 hours of monthly labor for employees and eliminates errors inherent in manual data entry procedures.

RFID tags, serving as asset identifiers, collaborate with IoT to enable asset tracking in manufacturing. Each tag features a unique ID linked to specific asset data, encompassing physical attributes, cost, serial number, model, assigned personnel, operational area, etc. RFID readers positioned at storage yard and construction site entrances scan the tags, updating cloud-stored data. Through this log, technicians can trace asset movements, compute utilization, and identify idle or underutilized machinery, thus scheduling preventive maintenance.

Enterprise Inventory Management

IoT-driven inventory management solutions aid manufacturers in automating inventory tracking and reporting, guaranteeing perpetual insights into individual inventory item statuses and locations, and optimizing lead times. These intelligent inventory management solutions purportedly save 20% to 50% of enterprise inventory carrying costs. Each inventory item is affixed with a passive RFID tag, bearing data pertinent to the item it’s attached to. RFID readers extract data from these tags, relaying data about RFID reader location and reading time to the cloud. The cloud deciphers item statuses and locations, furnishing this information to users.

Predictive Maintenance and Condition Monitoring

Predictive maintenance solutions anchored in Industrial IoT are anticipated to pare factory equipment maintenance expenses by 40%, generating annual economic value worth $630 billion by 2025.
