Structural Health Monitoring of Bridges
Dewesoft data acquisition systems are used in structural health and seismic bridge monitoring projects ranging from structural mechanics to continuous monitoring of large, complex structures. The systems provide distributed, high-channel-count and remote monitoring for highway overpasses, roads, buildings and bridges.

Hong Kong - Zhuhai - Macau Bridge Monitoring
The Hong Kong - Zhuhai - Macau Bridge (HZMB), officially the Hong Kong - Zhuhai - Macau Bridge, is a 55-kilometer (34 mi) bridge-tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. It is both the longest sea crossing and the longest fixed link on earth. The HZMB spans the Lingding and Jiuzhou channels, connecting Hong Kong, Macau and Zhuhai - three major cities on the Pearl River Delta. With a total length of 55 km, the HZMB is regarded as the longest sea bridge in the world.
One part of this monument's structural health monitoring system is the measurement of tri-axial accelerometers at the navigation spans. The purpose is to detect the occurrence of the ship impacting as well as to determine the global dynamic characteristics of the structure's viaduct bridges.
200 highest precision acceleration channels are needed, distributed over several kilometers. These channels are clustered into six independent data acquisition sub-systems. The data of each sub-system are stored locally and in parallel to a database engine running on a central server.

Vibration Analyzer for Tuned Mass Damper
Structures such as bridges, skyscrapers, staircases, stacks and antennas can all be excited to high levels of vibration by wind, earthquakes, nearby machines or traffic. Low natural frequencies and low natural damping are typical of such structures. The use of GERB Tuned Mass Damper (TMD) Systems can significantly reduce these vibrations.
Tuned Mass Damper (TMD) Systems limit the displacements of structures by absorbing and dissipating vibrational energy. Generally, they are passive systems and consist of vibration masses, springs or pendulums and visco-dampers. Each device is custom designed for its respective application.

Rugged & Distributed Data Acquisition
Dewesoft provides very rugged data acquisition units that can work flawlessly in a wide temperature range, under big stress and even in very humid and wet environments.
Data acquisition units can easily be distributed so you can place them close to the sensor placed on the structure. This means shorter sensor cabling which increases signal quality, decreases chances of cabling errors and cabling cost. DAQ systems can be distributed down to single channel.

Remote Data Monitoring & Storage
Dewesoft software offers easy and flexible configurations for your data flow. You can store data locally near the structure itself, or use any of the standard interfaces like OPC UA to send and store data remotely in the cloud or database. There is really no restriction on how to set up your data flow.
Dewesoft flexible licensing allows user to connect an unlimited number of view clients to monitor data in real-time without any additional cost.
