The ENMO® IT SEES plug-in – automatic alarm index creation

With the optionally available ENMO® IT SEES plug-in – a tool for the real-time detection of unnatural or conspicuous water conditions – the functionality of ENMO®hydro is considerably extended once again. ENMO® IT SEES analyses and evaluates fed-in data sets – i.e. classic water parameters and biomonitors – with respect to whether they fulfil the criteria of »conspicuousness«. ENMO® IT SEES determines the alarm index from all suspicious events with different weightings. Each irregularity increases the value of the alarm index by a value defined for the respective measurement. If defined thresholds are exceeded, ENMO® IT SEES generates a warning. When the highest threshold is crossed, the »announcement stage« is reached. Dynamic detection procedures such as the double-sigma test and Hinkley detector offer a sensitive detection of irregularities in the water and thus also significantly reduce the probability of a false alarm. ENMO® IT SEES was developed by bbe Moldaenke, Kiel and Hamburg’s water quality measuring network within the context of the research and development project “EASE - Development of Alarm Criteria and Incident Measurement in Measuring Stations for International Danger Prevention.”
