项目编号：BS-QD-001

本项目主要实现校园/公司/各类组织疫情防控管理，个人健康上报功能，分为三个角色：

管理员：主要管理学生、教师、班级、通知信息

教师：主要管理学生的健康上报信息，通知信息，请假审批信息

学生：主要进行健康上报，请假，通知查看等功能

系统通过图形报表的形式来统计相关的信息，界面美观大方，功能全面，是一个难得的前端项目。可以根据需要修改为比如公司疫情防控系统、社区疫情防控系统等等。

1.使用vue+element+vchar框架进行前端开发

2.使用nodejs+express+mysql+socket进行后台开发

3.前后端分离开发

4.数据库采用MYSQL+REDIS进行信息的存储

下面展示一下系统功能：

管理员登陆： admin /111111

后台首页：仪表盘

学生管理功能

可以通过EXCEL表格导入学生和老师

老师管理：同样可以通过EXCEL表格导入学生和老师

通知管理：

班级管理

学生登陆系统：znzbs005/111111

查看通知

每日健康填报

请假

个人信息管理

老师登陆

通知管理

请假审批：只能审批本班学生

个人信息修改

在线聊天

以上是展示的本系统的部分功能。

核心代码展示如下：
