bbe IT SEES IT Signal Event Evaluation Software The bbe IT SEES software is an alarm analyser and detector, i.e. a tool for the examination and evaluation of all kinds of sensor readings. It is based on the established bbe Alarm Index (AI) Viewer software for biomonitors. APPLICATIONS Link between data acquisition and alarm verification Monitoring stations detects significant events of multiple sensor readings in real time detects sudden changes in any signal combines event evaluation from different signals to detect alarm events while also limiting false alarms compensates for drift (e.g. diurnal shift in temperature). Integration into higher-level systems whether an alarm signal is present. IT SEES is effective for users of simple probes to assess on-going processes in the water systems under observation. Algorithms are made to detect changes in each observed signal. The user can choose: • upper and lower limits for the evaluation • a statistical short-term evaluation as a standard deviation with or without drift elimination • long-term evaluation Usually, events in different signals in the same time period are necessary to indicate a reportable alarm. An Alarm Situation The following example (right) describes a real alarm situation and its evaluation: The parameters for water temperature, pH, O² and conductivity were used to analyse the status of the water. Graph 1 displays the results of the combined data evaluation (AI = Alarm Index). Graphs 2, 3, 4 and 5 indicate sudden changes in the different parameters of the water. In this particular evaluation, the 'H‘ indicates an unusual change compared to previous data. Screenshots of measurement parameters: Alarm Index, temperature, pH, O² and conductivity

bbe IT SEES Real-Time Analysis of Multiple Sensor Readings EASE Project promoted by the German Federal Environmental Agency Berlin, supervised by the Hamburg Environmental Agency executed by bbe Moldaenke GmbH A combination of evaluation parameters is used to create the Alarm Index. Each measurement parameter adds a certain number of points (toxicity points) to the index until it exceeds the threshold of 100 when an alarm is triggered. IT SEES can be easily integrated into existing operational systems. Do you have any questions? Please contact us! Your local representative bbe Moldaenke GmbH...
