CASE STUDY However, the LoRaWAN sensor outputs weren't directly compatible with DFS' existing BMS. In addition, global had to integrate other sensors and devices from the existing infrastructure including myriad concentrators, hubs, routers, and switches. Altogether they were looking at BACnet, Modbus, LON and various RS-485 connections alongside LoRaWAN wireless sensors and actuators for HVAC and lighting. And all the disparate data had to feed into a system that would process and make sense of it. global weren't aware of anything that would provide a holistic answer. The company decided to begin its own internal, resource-intensive development project. Fortunately, soon after starting that project, global learned of the SmartServer™ IoT edge server from Dialog. In addition to communications protocol and device integration, SmartServer IoT includes open APIs for creation of unlimited applications and services and provides a powerful bridge between on-premises solutions and cloud services. Within just a few days, Dialog provided a proof of concept, and global adopted the solution. The Solution global associates devised a hybrid IoT / BMS solution integrating DFS' legacy BMS and infrastructure with edge computing, cloud enablement, the latest LoRaWAN wireless sensors. The fully integrated, data-driven control and monitoring system is based around the SmartServer IoT. LoRaWAN sensors monitor a wide array of conditions at each site including environmental (e.g., CO 2 , humidity, temperature), occupancy (i.e., motion detection), metering and load control (e.g., voltage, current, power, and energy), heat exchanger maintenance (i.e., vibration), and more. The sensors and other local devices feed into the SmarterServer IoT where a common data fabric called the IoT Access Protocol (IAP) abstracts the datapoints and converts them into BACnet datapoints. These datapoints feed into the BMS which can use the data to manage the building more efciently. The IAP handles all translations and data normalization, creating a digital twin of the universe of devices. Since the BMS sees each LoRa datapoint as a BACnet datapoint, there is no need to worry about the difference between a LoRaWAN air quality sensor and a hardwired building access sensor – or any other device. Within the centralized building management and control platform, each device appears in a common data layer, with its own alarms, control strategy and other operational parameters. The system collects and processes over 700 different datapoints at one DFS site alone – updating every minute on the edge, and it is scalable for evolving requirements. Control logic is enriched by fusion of LoRaWAN sensors Data is securely available to energy & occupancy analytics LoRaWAN devices augment traditional sensor & control networks !
