摘要:
A system (30) includes an analysis engine (34) and a notification engine (38) for selective notification of a condition (72) of an apparatus (26) monitored by a monitoring device (28). A method executed by the system (30) receives (116) data elements (58) from the monitoring device (28), processes (118) the data elements (58) to detect the condition (72) of the apparatus (26), and determines that the condition (72) defines an exception (74) to a normal condition (70) of the apparatus (26). A first notice (60) of the condition (72) is conveyed (146) to a responsible party (59) at a first instance of determination of the exception (74), and conveyance of a second notice (60) is prevented (140) at a second, subsequent, instance of determination of the exception (74). In addition, communication of the normal condition (70) of the apparatus (26) is prevented.
摘要:
A monitoring system (100) includes a machine (101) including at least one rotating component, at least one sensor (110,112) configured to detect a frequency of the at least one rotating component, a memory (206) configured to store data received from the at least one sensor, and a processor (202) is programmed to receive, from the at least one sensor, a signal including at least one frequency, convert the received signal to a digital vibration signal, modify the vibration signal to generate an envelope signal, synchronously oversample the envelope signal to generate a synchronous envelope signal, and transform the synchronous envelope signal into a frequency spectrum to isolate the at least one frequency.
摘要:
The present invention is a method for real-time testing of a control system for controlling a complex real world system. Real-time performance of a simulator is monitored and compared with a real-time clock of the real world system it is simulating and step-sizes for a simulation solver are continuously adapted by applying a modified variable step-size solver for running the simulation.
摘要:
A controller for using a first data item transmitted via a network to generate a second data item for controlling an entity to be controlled over the network, wherein the controller is characterized in being provided with: an adjustment unit for adjusting, with respect to the maximum delay time permissible on the network, the time by which generation of the second data item is started using the first data item after the first data item has been received; and a delay compensation unit, designed using a model of the entity to be controlled and the maximum delay time permissible on the network, for compensating for the delay of the first and second data items that can be generated using the network.
