Intelligent Edge Connectivity Highlights at Embedded World 2018

Last week at Embedded World in Nuremberg, Germany we teamed up with Silicon Labs to showcase smart edge Internet of Things (IoT) technology with simplified integration of cellular IoT connectivity and dramatically reduced development challenges. Built as a heating, ventilation, and air condition (HVAC) reference application, we demonstrated a complete connected system with a local liquid crystal display (LCD) based graphical user interface, temperature sensors, fan, and cloud connectivity for remote monitoring and control.

At the heart of the demo is Silicon Labs’ new Giant Gecko Series 1 microcontroller (MCU) driving the local LCD and user buttons for temperature set point control, temperature sensing, and fan control. The system also demonstrates the innovative local distribution of edge intelligence by taking advantage of Micro Python based data transformation capabilities and smart Message Queuing Telemetry Transport (MQTT) connectivity on the Digi XBee3 Cellular in combination with the Micrium embedded application running on the Silicon Labs MCU. Integrated AWS IoT cloud connectivity allows for remote access and control of the simulated HVAC system by offering mobile set point control and status monitoring.

HVAC systems are a critical component as part of new building automation concepts in smart city applications, residential structures, and industrial buildings, providing intelligent energy management and improved air quality. A connected HVAC system delivers a host of benefits for the end-customer as well as device manufacturers and service organizations:

Easy Remote Access and Control 

  • Easy and always available management by end-customers
  • Remote troubleshooting for service organizations

Enhanced user experience

  • Self-learning, intelligent comfort settings based on behavior patterns
  • Potential for future cloud services based integration such as conversational user interfaces

Improved operational management and cost

  • Remote firmware upgrade for security updates and new features
  • Centralized data analytics of operational history to optimize equipment performance and provide detailed usage insight
  • Intelligent optimization of cellular connectivity cost through Digi XBee3 smart modem integration

New Service Concepts

  • Improved reliability through preventive maintenance such as early failure detection of a fan or burner
  • Optimized replacement of consumables such as filters

The system is more than just a connected HVAC demo. It also shows how IoT concepts can deliver immediate value and benefit, while providing a platform with built-in potential for new features and capabilities in the future. It also demonstrates the opportunities that are opening up when edge intelligence and cloud intelligence come together and combine the traditional “big data” concept provided by the cloud with “intelligent data” from the edge. Ultimately, this will reduce the amount and improving the quality of “big data” generated by IoT edge devices while also optimizing the scale of local network traffic required to exchange data between the edge and the cloud, including optimizing the cost of the underlying cloud services. All of those are concepts are required to drive scalability and efficiency of virtually every IoT application combined with the massive scale of connected devices we are going to see.
