铃音定时播放系统

1、.铃音定时播放系统程序功能程序的主要功能是定时播放音乐。为了符合学校的需求，本程序设定了方案为主的方式，进行配置。在一个方案可以随意建立256条以内的项目，每条项目有描述，时间，音乐地址三项描述，可以在24小时的时间内自动播放。本程序还内置了4种方案，进行修改后可以符合学校不同季节不同的作息时间安排。程序流程图1 保存当前方案2 保存内置的方案3 保存音乐播放数据1. 循环更新时间2. 按时间定时播放音乐3. 显示下一项目1. 添加项目2. 删除项目3. 按时间进行项目排序程序代码MusicF.pro#-# Project created by QtCreator 2015-08-07T08:
