Abstract: A system and a method for parameter optimization with adaptive search space and a user interface using the same are provided. The system includes a data acquisition unit, an adaptive adjustment unit and an optimization search unit. The data acquisition unit obtains a set of executed values of several operating parameters and a target parameter. The adaptive adjustment unit includes a parameter space transformer and a search range definer. The parameter space transformer performs a space transformation on a parameter space of the operating parameters according to the executed values. The search range definer defines a parameter search range in a transformed parameter space based on the sets of the executed values. The optimization search unit takes the parameter search range as a limiting condition and takes optimizing the target parameter as a target to search for a set of recommended values of the operating parameters.

Abstract: A method for monitoring a manufacturing apparatus includes collecting a control signal, of a controller and a corresponding sensing signal, of the manufacturing apparatus over a predetermined period of time; segmenting the control signal and the corresponding sensing signal to obtain at least one control step; calculating a character of the controller based on at least one of the control signal, the sensing signal, the at least one control step, or information from a user manual; generating, based on the character, a health index indicating health of the controller; and generating a warning signal when the health index exceeds a predetermined threshold.

Abstract: A method for identifying an electric appliance and an apparatus and a system thereof are provided. The method includes the following steps: respectively collecting a first power event on a first phase power and a second power event on a second phase power; when the first power event and/or the second power event are collected, determining whether the first power event and the second power event substantially occur at the same time; if not, identifying an unknown electric appliance as a first type electric appliance; and if yes, determining whether the first power event and the second power event are substantially the same, wherein if yes, identifying the unknown electric appliance as a second type electric appliance, and if no, identifying the unknown electric appliance as the first type electric appliance.

Abstract: A method and a system for monitoring electric devices coupled to a power circuit are provided. The method includes: obtaining a first power feature of the power circuit at a time; obtaining a second power feature of the power circuit at another time; determining whether a power feature variation occurs according to the first and second power features. If the power feature variation occurs, the method further includes: adjusting the first power feature to a first normalized power feature according to a reference voltage; adjusting the second power feature to a second normalized power feature according to the reference voltage; recognizing that a status of one of the electric devices is changed from a first status to a second status according to the first and second normalized power features. By applying the method, whether the electric devices are switched on or off may be accurately recognized.
