一、界面设计

1.1安装pyqt5

pip install pyqt5-tools

运行 Python安装目录下 Scripts\pyqt5designer.exe 这个可执行文件
1.2创建用户主窗体
进入设计界面创建一个main window
拖动添加控件，创建用户主窗体
具体每个控件怎么使用可以咨询：robot

1.2创建用户子窗体

创建qdockwidget,拖动添加控件，创建用户子窗体——检测功能窗体
……创建其他功能子窗体

1.3创建管理员主窗体

进入设计界面创建一个main window
拖动添加控件，创建管理员主窗体

1.4创建管理员子窗体

创建qdockwidget,拖动添加控件，创建管理员子窗体——用户信息管理功能窗体

……创建其他功能子窗体

1.5创建系统登陆界面

进入设计界面创建一个main window
拖动添加控件，效果如下

二、环境搭建

2.1pyqt5工具配置

将ui转化为py文件工具配置参考地址1
qrc转_rc.py工具配置参考地址2

生成的_pyuis/user.py文件

2.2mysql5.7安装

安装包链接: https://pan.baidu.com/s/1uA–xggCc0HKXuA3IpluBg 提取码: 4r5x
安装需要勾选MySQL Server 以及MySQL Workbench进行安装

安装出现关于Microsoft Visual c++ 2013的报错可以看看这个

三、编程实现

3.1初始化数据库

确保数据库处于运行状态

初始化数据库
a_data_sheets/lowp.sql文件

drop database lowp;

create database lowp;

use lowp;

create table User
(
	Student_Id varchar(20) primary key, 
	Phone_Num varchar(20), 
	Name varchar(20) not null, 
    Password varchar(20) default "12345678"
);

create table User_Detailed_Info
(
	Student_Id varchar(20) primary key, 
    Gender varchar(20),
    Nation varchar(20), 
    Data_Birth date, 
    Id_Num varchar(20), 
    Pre_Address varchar(20), 
    Record_School varchar(20)
);

create table User_Set_Up
(
	Student_Id varchar(20) primary key,
	Bg_Color varchar(20) default "#EFEFEF",
	Bg_Picture longblob,
    Pellucidity double default 1.0,
	Font_Color varchar(20) default "#000000",
	Font varchar(20) default "隶书",
    Font_Size int(10) default 12,
    Tcp_Ip varchar(20) default "127.0.0.1",
    Tcp_port varchar(20) default "3306"
);


create table Expert
(
	Numbering varchar(20) primary key,
    Name varchar(20) not null,
    Areas varchar(20) not null,
    Phone_Num varchar(20) not null
);

3.2创建用户数据库sdk文件

_mysqlsdk/login.py文件
