Design And Implementation Of Embedded Court Self-Help System Based On Qt

In recent years,with the rapid development of society and the increasing demand for information technology,embedded products have blossomed in all areas of life.Whether it is medical electronics or court self-service terminals,all involve embedded.Systems,embedded products are gradually becoming an integral part of everyday life.The vast majority of the court's way of doing things is still the traditional window manual processing.The parties spent most of their time in the queue,window query,filling in information,etc.,causing the service hall to be overwhelmed and the service is not good.The continuous development of embedded linux technology has promoted the development of the court self-service system.The wide application of the court self-service system,along with the need to equip these self-service terminals with a beautiful,simple and easy-to-use graphical user interface,making it easier and more convenient for the public to use embedded products,Qt as a cross-platform The graphical user interface system provides users with a beautiful and easy to operate graphical interface.Therefore,the research of Qt-based embedded court self-service system is of great significance.The main research contents of this paper are as follows:(1)Analyze the functional outline of the court self-service system.The court self-service system mainly implements Qt-based user self-service filing,"one-stop" service function.(2)Design and design the entire hardware circuit of the court self-service system.This article selects Rockchip's RK3399 chip as the main control chip of this self-service system.PCB design is adopted for the motherboard and peripheral modules by adopting the design concept of “motherboard + peripheral module”.(3)Based on the Linux operating system,the software design of the court self-service system based on Qt mainly includes the transplantation and cutting of the Linux operating system,the development of the underlying device driver and thedevelopment of the upper layer Qt-based application layer software.The module introduces the core of the upper layer application The realization process of function modules includes self-service filing,map guidance,case inquiry,form printing,help button,and dual-screen different display function modules.The court self-service system designed in this paper has been debugged and tested to achieve the expected demand function.
