2. SP-1000B
Monitoring and Diagnosis System for Bridges
www.sitrackvibes.com
The SP-1000B system is a powerful tool
devoted to the construction and civil
maintenance industry that allows automatic
structural health monitoring and diagnosis on
bridges. The main purpose is the surveillance
of the structure for safe operation and for
determining optimum maintenance schedule.
The SP-1000B system performs an incipient
and automatic analysis of probable failures
operating in a threshold prior to their
occurrence. The system works automatically
and online detecting and evaluating changes
on the dynamic response of the structure,
allowing fast response in case of anomalies.
The SP-1000B system performs automatic
data-trend analysis for the determination of the
remaining life of individual components and of
the structure as a whole. These unique
features allow optimization of the maintenance,
significantly reducing costs and improving
safety.

Instrumentation
Sitrack Vibes has subscribed technology development agreements with
several world-class scientific institutions for the purpose of developing
instrumentation for specific applications.
The SP-1000B system uses signals from sensors located within the structure and
enviromental signals.
The system supports sensors already installed on the
bridge and additional sensors are installed as required.
Signals from various sensors are used, including:
Accelerometers
Strain gauges
Displacement sensors (LVDT, linear
potentiometer)
Temperature sensors
Wind velocity and direction
SitrackVibes provides instrumentation and installations certified for use in marine
environment.
Local Monitor
Monitoring, analysis, and diagnosis functions are carried out by a local monitor installed
locally. This monitor receives field signals and performs data conditioning, filtering, and
acquisition tasks. Information is processed by the monitor. Algorithms and analysis
models for the structure are the sole property and design of Sitrack Vibes.
The SitrackVibes monitor links to pre-installed monitoring systems, with the capability of
analog and digital data interchange.
The local monitor generates on-line information on the status of the bridge components,
as well as alarm and temporary reports. This information is presented locally and send
to Sitrack Vibes facilities for offline postprocessing.
The monitoring and diagnosis results are available via web for remote access by
authorized users.

Virtual diagnosis
A virtual diagnosis of the bridge and
individual components is
accomplished in case of abnormal
event detection. The virtual diagnosis
uses a finite element model of the
structure, feeded with actual
measured data.
Virtual diagnosis allows in-deep
analysis of the structural components
behavior. Static and dynamic analysis
are automatically executed, revealing
real life stress and strains on the
structure. Fatigue life determination
and accumulated fatigue damage can
be estimated with virtual diagnosis
system.
Statistical post-processing of the
information is automatically
accomplished by dedicated servers.
The Virtual Diagnosis system is a
SitrackVibes development and its
features are unique in the market. It
allows intuitive and comprehensive
understanding of the structure
behavior under all normal and
exceptional loads. 3D plots of the
model are presented, allowing the
user to view component-by-
component in normal and deformed
status.
