Distributed and synchronized measurement refers to the process of collecting and analyzing data from multiple sensors that are distributed over a large area and are synchronized to a common time reference. Distributed DAQ systems typically have measurement modules installed close to points of measurement reducing cable clutter, and measurements are less prone to noise due to short sensor cables while remaining connected and synchronized to the controller.
Where is Distributed Remote Monitoring used?
Distributed remote monitoring is used in applications such as monitoring the health and performance of distributed systems, monitoring the status of industrial equipment, and monitoring the environment or environment-related systems. Structural health monitoring (SHM) can also be used for predictive maintenance, energy management, and data analysis. This type of monitoring is becoming increasingly important in many industries, as it allows for the efficient and effective monitoring of multiple systems from a single point of access.
Why choose Gantner for Distributed Measurement?
Distributed measuring systems may easily be configured with our Q.series X measurement modules and Q.station X test controller (several versions available). The modules are connected to the test controller via serial RS-485 interfaces with very high data rates. Despite the distributed set-up, measurement is in sync with a maximum jitter of 1 μs. The Q.station X test controller provides different interfaces for connecting a PC and automation systems depending on the controller type.
A special advantage of this structure is the simultaneous availability of the measurement data in real-time through a deterministic real-time Interface and the block-by-block transmission of large amounts of the same data over standard Ethernet.
Distributed Monitoring and Control
Q.series X modules provide the perfect solution in installations where multiple signals are widely dispersed and require simultaneous sampling and comparison (less than a microsecond). In the structural testing of bridges and wind turbines, where a deviation of only a few milliseconds in the measurement data can result in significant dynamic analysis errors, this functionality is vital.
- Typical variables like strain, acceleration, displacement, tilt or forces are acquired, recorded and converted into characteristic values.
- For example, in the bridge application (see figure below), measured values can include traffic load, deflection, misalignment, bearing load or vibration with FFT calculation and damping behavior. This information is processed locally, and the relevant information can be stored and streamed within your IT infrastructure for further decision making.
Accurately Synchronize Distributed Measuring Systems
Synchronization of measured data is required if signals have to be correlated. This is important in various structural analysis and testing applications. Depending on the dynamics to be measured, deviations of only a few milliseconds produce measurement errors of up to several percent.
Logging without Limits
Recording (logging) of measurement data is an everyday task for measuring systems. Especially in the structural monitoring of wind energy plants and buildings, it is useful to reduce data load from the measured quantities to only show the maximum, minimum, mean and standard deviation parallel to the raw data, for example, in 10 minute intervals. The Q.series offers a very convenient solution.
