GWIN
Government-Wide IoT Network (GWIN)
Introduction to Government-Wide IoT Network (GWIN)
To assist digitalisation of E&M equipment, the Department is building a government network of wireless sensors installed throughout Hong Kong to support various smart applications for the improvement of public service quality.
Traditional sensors would each require a 4G connection to connect to central servers. In the GWIN network, sensors are connected to gateways via the low power and private LoRa (Long Range) network. The network with low power consumption reduces the cost and complexity of installing the sensors, and improves the security of the system and data without the need of using a third-party network.
Watch this video as we walk you through the benefits, objectives, the LoRa technology, and the pilot applications of GWIN.
Applications of the Network
Infrastructure and Applications of GWIN - Presentation Slides
- Improving maintenance and repairs of E&M equipment in buildings
- LoRa gateways and sensors are already installed at the EMSD Headquarters. Sensors including temperature, humidity, and vibration sensors provide operation data for lifts, escalators, photovaltic panels, and chillers. The application server would closely monitor the status of our equipment, enabling fault alarm, remote diagnostics, and predictive maintenance.
- Managing utilization of public facilities
- Occupancy sensors installed in meeting rooms and parking slots in carparks report the occupancy status of these facilities to a smart reservation system, enabling online facilities booking and better resource management.
- Flood monitoring and underground pipe leakage analysis
- The flood monitoring system was installed at sites including Shing Mun River, Tai Po River and Heng Fa Chuen. It uses ultrasonic water level sensors connected to LoRa gateways which can be swiftly and easily deployed.
- Underground pipe flow meters are retrofitted with LoRa modules, providing water flow data for identifying locations of water leakage.
