For the hardware specifications other suppliers than those specified will be accepted only for sensors when the technical specifications are at least as good as those shown for example.

For the instrumentation hardware, all sensors, data acquisition units, cables, PCs, etc. being a part of the wind and structural health monitoring system shall be delivered and kept on work site at latest when work site has been established and approved by the Engineer.

The Engineer will inspect the delivery at work site. Works will not start before the Engineer has approved the delivery.

The system is divided into three components, namely the On-Structure Instrumentation System (OSIS), the Portable Data Acquisition System (PDAS) and the Computer System for Operation and Control (CSOC).

The OSIS system monitors the following parameters:

            Load-Effects

Wind measurements

Temperature measurements

Traffic measurements

            Environmental effects

Humidity

Rainfall

            Bridge response

Displacement

Stresses and strains

Dynamic characteristics

The PDAS is only used for monitoring dynamic characteristics for cables.

The WAHMS will be based on a common data acquisition network for the OSIS part of the system acting as interface to the CSOC system. The OSIS hardware will be the same as the PDAS hardware, just contained in a safe cabinet and connected to the permanent sensors.

The OSIS is employed to monitor the load effects, environmental effects and response of the bridge and is composed of the following components:

Sensor system       Sensors for monitoring load effects, environmental effects and response of the bridge by anemometers, temperature sensors, accelerometers, strain gauges, displacement transducers and GPS.

Distributed I/O      Open industrial networks for moving data acquisition and control functions into the field will b used. By using robust networking technology to position intelligent, distributed data acquisition I/O devices closer to the sensors, significant cost savings and improved performance can be obtained. The OSIS will be based on the National Instruments distributed I/O systems that work with the following networks:

       Ethernet TCP/IP

       RS-232 and RS-485

       Wireless

       FOUNDATION Fieldbus H1

                            Distributed I/O systems include special capabilities to improve reliability, onboard diagnostics, and maintenance to maximize system uptime. Intelligent distributed systems can help implement embedded, deterministic control systems. The system can at a low cost be added further data acquisition points after installation if required. 

Network System    The network contains of hubs and repeaters from bridge to controlling computer, which is also placed at bridge. At bridge distributed I/O points will connect by standard Ethernet LAN cables.

Controling PC        The controlling computer is responsible for carrying out the execution and control of OSIS. Overall data acquisition will be managed by National Instruments Labview software. An easy-to-use Web-enabled human machine interface (HMI) and supervisory control and data acquisition (SCADA) software system for process and supervision control applications. The software will also carry out post-processing, when not performed local by the distributed I/OI point, and archiving in MatLab format.
