1、.鈴音定時播放系統程序功能程序的主要功能是定時播放音樂。為了符合學校的需求，本程序設定了方案為主的方式，進行配置。在一個方案可以隨意建立256條以內的項目，每條項目有描述，時間，音樂地址三項描述，可以在24小時的時間內自動播放。本程序還內置了4種方案，進行修改后可以符合學校不同季節不同的作息時間安排。程序流程圖1 保存當前方案2 保存內置的方案3 保存音樂播放數據1. 循環更新時間2. 按時間定時播放音樂3. 顯示下一項目1. 添加項目2. 刪除項目3. 按時間進行項目排序程序代碼MusicF.pro#-# Project created by QtCreator 2015-08-07T08:
