Title The Analysis and Design of the Power Quality Analyzer Interface based on Linux
Abstract
The essay uses Qt Designer to complete the interface design of the power quality analyzer based on the deep understanding of the Linux operating system. With the development of the economy and society, many problems of power quality have become increasingly prominent, and much more attention has also been paid to it. Therefore, the essay firstly analyzes the functional requirements of the power quality analyzer and build a hierarchical structure about the interface of the analysis system. Then, based on the Linux system, we use Qt Designer to complete some work, such as building a project, building the graphical interface, automatically corresponding of signals and slots and automatically generating of the main frame code for the program, to complete the design of the interface. The essay focuses on understanding and perfectly using Qt software, and using the Qt programming mechanism to complete the interface design of the power quality analyzer.
