Events, Alerts and Alarms
4.6.7 Events, Alerts and Alarms
- Threshold surpass detection. The SANY system shall be capable of detecting threshold surpassing. For instance in the field of air quality measurement, excess pollution of the environment can be asserted if sensor measurement data have reached defined thresholds. - Alert algorithms. Typically, an alert will result if a combination of observed variables is no longer in a defined region the event of variables departing from this region. Alerts cause application level procedures andor workflows to be executed as a reaction to the event. - Interfaces for alarm management. Alarms involve communication procedures with the emergency management agencies or the public to warn about an imminent hazard and to initiate emergency procedures such as evacuation. Note: Alt hough used here in the requirements section, the term “alarm” is not used in the SensorSA as a distinguished architectural term. It is considered to be a special type of an alert see section 6.3.3. - Tracing. Tracing requirements address the need to document what information sources were used as a basis for the decisions taken and the decision making process itself. The purpose is to be able to provide a retrospective justification of decisions made, which may later be contested by parties seriously affected. - Models. The SANY system shall provide in general - a model service catalogue, where all available services may be selected by the user - an execution management service handling inputoutput and, optionally if expedient for performance reasons, data by reference - the capability of using the output of models and fusion algorithms as sensor values without changing the system. - In addition to basic support for models and model wrapping to integrate the models into the SANY service network, the following model-specific functionality is required: - Gathering of applicable source impact models - Domain skills compilation - Library of models as processes SANY D2.3.4 Specification of the Sensor Service Architecture V3 Doc.V3.1 Copyright © 2007-2009 SANY Consortium Page 47 of 233 - Library of geo-statistical analysis as processes - Predictive models for adaptive sampling - Spill advection dispersion modelling - Forecasting risks water quality, bathing water, beach closed - Modelling long-term degradation of ecosystems - Improved soil models4.6.8 Decision Support
