Design And Implementation Of Configuration Tool For Subway Passenger Information System Based On Qt

Subway passenger information system is responsible for providing a variety of multimedia information to the passengers and the operators. There exiting such problems as long development cycle, high maintenance costs, low software reuse rate, uncertainty demand and frequent changes during the development process. Therefore, the design and implementation of the passenger information system configuration tool has certain theoretical significance and value.This thesis presents a new method for designing the interface of the multimedia information display module based on configuration. The method can be divided into two parts: the configuration tool which is designed based on Qt is responsible for editing and configuring the interface; the display module is responsible for displaying information and monitoring. The design separates the configuration function and the display function. The interface can be displayed in different types of display devices. The design improves the flexibility of the configuration and the reuse rate of the code, with higher practical value.Firstly, the subway passenger information system and the configuration technology are introduced and the significance of the research in this thesis is proposed. Then the function demands of the configuration tool are analyzed and the overall function framework of this software is built. Based on the overall function framework, the realization scheme of each function is introduced. Finally, in the simulation test environment, the software is tested in detail to ensure the reliability and accuracy of all the functions. The configuration tool plays an important role in designing the display module of the subway passenger information system. Currently, this software has been applied in a subway project and works well.
