Research on Rapid Construction Technology of Human Machine Interface Based on Component Paper

This paper proposes a rapid construction technology of human machine interface (HMI) based on components in order to solve the problems such as inconsistent interface style, poor code reusability and low development efficiency in the development of traditional information system HMI. Based on analyzing a large number of HMIs of information systems, the technology extracts interface elements to form a reusable general component library. Adopting the user-defined control management model based on Qt platform, the general components of information system HMI are integrated. The topic management technology, attribute visual editing technology and component communication technology based on signal/slot mechanism, which support one-key switching of interface style, are put forward. Therefore, the rapid construction of information system HMI is realized. This paper selects an interface in a practical project and compares the effect of the interface constructed by the same developer with and without this technology. The results show that the rapid construction technology of HMI can effectively solve the above problems. At present, this technology has been widely used in command-and-control system, combat system, state monitoring system and other complex information systems.
