Enhancing RTLS capabilities with ESL integration

Real-Time Data Synchronization and Automation

At the heart of Ubudu’s solution is the ability to automatically synchronize data associated with ESLs. Every time an ESL transmits its BLE signal, Ubudu’s RTLS updates its position and synchronizes any field linked to its MAC address. This seamless integration means that work orders and asset statuses are updated in real time, eliminating the need for separate APIs or manual updates.

For example, when a work order moves through different production zones, the ESL attached to the asset can automatically display:

• The current operational status.
• The next scheduled task.
• Alerts, such as a “Non Conforme” warning when an asset enters a designated non-compliant zone.

This level of automation not only improves operational efficiency but also ensures that every update is accurate and immediate.

Advanced rule engine for dynamic content updates

Ubudu’s integrated rule engine takes full advantage of the ESL and RTLS combination. It allows you to set custom rules that trigger actions based on an asset’s location or status. Some practical applications include:

• Dynamic Content Display: For instance, if an asset enters a new zone, the ESL can automatically update to show the next operation or display a warning message.
• Real-Time Alerts: The system can send notifications to technicians if a tool is detected outside a designated repair area. This helps prevent operational delays.
• Personalized Messaging: Operators can customize alerts and status updates to reflect specific operational conditions, ensuring that the information displayed is always relevant.

Such dynamic capabilities enable manufacturers to create smart workflows that adapt on the fly to the changing production landscape.

Integrating with other systems

The power of Ubudu’s RTLS is further enhanced by its ability to integrate seamlessly with third-party systems such as MES (Manufacturing Execution Systems) and ERP (Enterprise Resource Planning) systems. This interoperability means that the data captured by the ESL-enhanced RTLS can be used to:

• Optimize production flows: Automatically adjust production schedules based on real-time inventory levels and work order statuses.
