Sensor data acquisition and data processing

From this, static source parameters such as seismic potency can be computed. Agent-based modelling was originally based on social simulation. Distributed sensor network[ edit ] If a centralized architecture is used in a sensor network and the central node fails, then the entire network will collapse, however the reliability of the sensor network can be increased by using a distributed control architecture.

Another standard system, SEAS, provides a backup system for delivering data about current conditions. Data Merging and Extraction Combining data from individual channels of different wave files, and extracting part of data from a wave file are supported.

The methods developed for the ShipTracker pages are being applied to other tracked entities such as marine buoys and instrumented marine mammals.

Wireless sensor network

For example, in sensing and monitoring applications, it is generally the case that neighboring sensor nodes monitoring an environmental feature typically register similar values.

Online collaborative sensor data management platforms[ edit ] Online collaborative sensor data management platforms are on-line database services that allow sensor owners to register and connect their devices to feed data into an online database for storage and also allow developers to connect to the database and build their own applications based on that data.

Device Test Plan supports connection with external systems through serial communication. Anti-aliasing filters are specified according to the sampling rate of the system and there must be one filter per input signal.

Providing security to aggregate data in wireless sensor networks is known as secure data aggregation in WSN. Different stimuli can be generated and the response can be analyzed in different ways. The width and color of the trackline decreases with older observations, making it easy to see where the ship has been.

Creating this site required developing tools that would provide near real-time display of tracked items i. Images created include an overview image and ship-specific zoomed-in images. The signal from these transducers is either a voltage or a mA current. Options are provided to either display all data points slow or only display one data points per vertical raster line fast.

Data Acquisition & Control

Data acquisition systems abbreviated with the acronym DAS or DAQ typically convert analog waveforms into digital values for processing. Extensibility Plugin modules are available from IMS to add certain specialised functionalities to the software, if required.

More interested readers would refer to Butun et al. Picking Phase Arrivals Automatic picking of the body wave arrivals can be performed using one of a variety of techniques, including AIC methods, AR methods and phase polarisation methods.

For many transducers the supply will be low voltage DC, but for transducers based on capacitance measurement an AC supply may be required. An open cold-junction measuring box connected to data acquisition hardware Filtering Filtering reduces noise errors in the signal.

Measurement Computing offers easy to use data acquisition (DAQ) systems and data logger hardware and software for test and measurement applications.

What Is Data Acquisition?

Editor's note: The National Oceanic and Atmospheric Administration (NOAA), through the Office of Oceanic and Atmospheric Research (OAR), conducts research and gathers data on the oceans, atmosphere, space, and sun.

Wireless sensor networks can be used to monitor the condition of civil infrastructure and related geo-physical processes close to real time, and over long periods through data logging, using appropriately interfaced sensors.
