The Västerbron in central Stockholm is a steel arch road bridge and is one of the major bridges of Stockholm, opened in 1935. It is also famous for being the toughest passage of the Stockholm Marathon. A wireless sensor system was installed during this summer on the structure. The system consists of 5 strain gauges, 1 inclinometer, 2 three directional accelerometers and 1 temperature sensor. The structure will be monitored with the IoTBridge Bridge Monitoring System. This includes sensor integration modules, wireless gateways, communication modules, MQTT Message Broker, GOST database for aggregation and storage of measurements and cloud infrastructure with algorithms and machine learning modules. IoTBridge and the KTH Royal Institute of Technology in Stockholm have developed a machine learning method to improve the accuracy in damage detection using acceleration data.
IoTBridge is focused on developing and marketing products and services for Bridge Health Monitoring using IoT and AI technologies. IoTBridge Sweden is a subsidiary of CNet. Read more at www.iotbridge.se.
