Data collection system, abnormality detection method, and gateway device
A data collection system pertaining to one embodiment of the present invention collects time-series data which is output from sensors installed on equipment which is a monitored object and carries out detecting an abnormality of the equipment. The data collection system stores plural fault models as data for comparison with time-series data and, in a learning process, determines a range to examine within time-series data by comparing the time-series data with each one of the fault models. An abnormality detection process includes extracting a partial frequency spectrum to examine from the frequency spectrum of time-series data, using information on the range to examine within the time-series data determined through the learning process, and carrying out detecting an abnormality of the equipment using the extracted frequency spectrum.
Load management for displaying an alarm signal indicator
A method for visually displaying a facility mimic diagram of a technical facility which has an operator station server and an operator station client, wherein the method includes transferring the facility mimic diagram from the operator station server to the operator station client, where the facility mimic diagram includes an alarm signal indicator, communicating a duration for visually displaying the indicator, visually displaying the facility mimic diagram with the alarm signal indicator, informing the operator station client about an emergence of a new alarm signal in the management system via a message, determining a value an actual display time has to visually display the alarm signal indicator, determining whether a display time for the visual display of the alarm signal indicator with the new alarm signal would overshoot the value of the duration, limiting the visual display of the alarm signal indicator when the available duration is overshot.
Controlling and maintaining operational status during component failures
A system, a control unit, and a method for controlling operation of a technical system are provided. The technical system includes a plurality of sensors. The method includes receiving first sensor data from a first sensor of the plurality of sensors.
