基于 6818 的电子抽奖系统北京理工大学珠海学院 2020 届本科生毕业设计基于 6818 的电子抽奖系统摘 要本电子抽奖系统,是一款可以在 ARM(cortex-A53)平台和 LINUX 操作系统上,以QT 为框架,C/C++为语言基础实现的抽奖平台的程序。本课题设计一种,用户可安全进行注册登录,密码加密,现状及发展趋势简易可靠的电子抽奖系统。用户数据用数据库保存,方便下次登录。使用 QT 中的 ui 界面设计师实现界面跳转。管理员可以更改中奖概率。它可代替传统抽奖方式,公平性、实用性、可靠性、成本等因素都十分可观,推广应用前景广阔,可以使用于各种各样的需要抽奖的活动中。关键词:ARM;LINUX;QT;C/C 数据库;交叉编译 1北京理工大学珠海学院 2020 届本科生毕业设计Electronic lottery system based on 6818AbstractThis electronic lottery system is a lottery platform program that can be implemented on ARM (cortex-A53) platform and LINUX operating system, using QT as the framework and C / C ++ as the language foundation. This topic designs a simple and reliable electronic lottery system in which users can safely register and log in, password encryption, current status and development trend. User data is stored in a database to facilitate the next login. Use ui interface designer in QT to realize interface jump. The administrator can change the probability of winning. It can replace the traditional way of lottery. It has considerable factors such as fairness, practicability, reliability, cost and so on. It can be widely used in all kinds of activities that need lottery.Keywords: ARM; LINUX; QT; C / C ++; cross compilation2北京理工大学珠海学院 2020 届本科生毕业设计目 录1 前言 .............................................................. 5 1.1 本设计的目的、意义及应达到的技术要求 ........................ 5 1.2 本设计在国内外的发展概况及存在的问题 ........................ 5 1.3 本设计应解决的主要问题 ...................................... 5 2 本设计 .......
