Human-computer interface capable of defining layout and content flexibly of SACDA upper computer

Abstract

The invention discloses a human-computer interface capable of defining layout and content flexibly of a SACDA upper computer. A content management concept in a GUI development framework is utilized, and a content display class contained with content and a display area class contained with content containers and a content manager class switching the content container in the display area dynamically according to demand of a user are defined, so that a window of the human-computer interface can display any kind of content, layout management function provided by the GUI development framework is utilized, and a mode is designed, so that the user can dynamically divide the display area into arbitrary multiple windows, or multiple windows are merged, and the size can be adjusted freely according to the content of the window. The human-computer interface capable of defining the layout and the content flexibly of the SACDA upper computer has the advantages of being flexible in extension and convenient to operate.

Description

technical field [0001] The invention relates to a SCADA upper computer man-machine interface capable of flexibly defining layout and content, and belongs to the technical field of distribution network automation application systems. Background technique [0002] Data Monitoring and Acquisition System (SCADA) Host Computer Human-Machine Interface (HMI) system acts as an interaction medium between the system and users, and graphically converts all the information and operations required by users into a form that is easy for users to understand. This information usually includes: [0003] 1. Collected field data. Through the screen configuration, the on-site data is displayed in text, graphics, images, animations, sounds, etc.; [0004] 2. Real-time alarm. The user pre-defines the alarm rules for the on-site data that are the focus of attention, and the HMI system generates alarm information based on the received real-time data, and actively pushes it to the user through sou...

AI Technical Summary

Problems solved by technology

The window type, arrangement, position, and window size of SCADA HMI multi-window are generally relatively fixed, and it is impossible to flexibly release unnecessary display space or adjust the window size to fit the display content according to user needs

[0010] 2. The window display content is single

The windows that make up the HMI can only display customized content. The screen display window, as the main window for user monitoring and control operations, can only display the screen files in a specific format generated by the screen configuration tool, and the screen configuration tool usually revolves around Designed for SCADA functions, providing functions such as drawing primitives, defining animations, etc., when faced with the interface requirements of other types of applications, it is impossible to produce a picture that meets expectations

Although some SCADA HMI products adopt the method of embedding graphical plug-ins, which can realize the display of some complex charts, but in the face of the increasingly diverse interface requirements of users, the expansion capabilities provided by this method are far from enough

[0011] 3. The interface expansion method of external third-party programs cannot adapt to the increasing degree of system integration

This method can solve the scalability problem of SCADA HMI. However, the HMI implemented by the third-party program exists outside the SCADA HMI. This implementation method not only breaks the overall sense of vision and operation of the entire SCADA system HMI, Moreover, the function window opened separately will cover all or part of the original SCADA HMI display area, hindering the normal monitoring work of the user

[0012] 4. For the HMI designed in the traditional way, every time a new application system is developed, a new HMI needs to be developed, which greatly increases the development workload of a new application system and also increases the later maintenance cost of the system
