基于RFID,QT,MYSQL开发的医疗电子病历系统

没事做，跟着模版随便做了一个电子病历系统，功能很简陋，界面也不太好看，各位大神看到别见怪啊~

功能包括有通过RFID读写器读取S50卡中的卡号把病人详细信息存入数据库、通过RFID读写器读取S50卡把病人的详细信息从数据库中进行读取并显示到QT程序界面上、在QT程序中进行病人信息的查询，包括修改与删除、计费功能（通过读取卡号，可进行对账户的充值与扣费）

随着物联网技术的成熟，物联网可以应用到各方各面，无论家居，农业，医疗等等都可以利用到物联网技术。而物联网技术的核心技术有：应用技术、网络技术和感知技术。我们所设计的系统正正利用了物联网的核心技术：感知技术中的RFID。在以前，病人去医院看病必须带上病历，而纸质不易保存，易潮，易脏。于是我们设计的电子病历既解决了纸质病历的问题，更加在此中增加了结算和电子钱包的功能。

电子病历是高质量，更快捷，更方便的医疗系统，电子病历不仅可以用于病人的随身携带，而且只需要带一张不到20克的卡，就可以不带钱去看医生。电子病历系统更加合理化，信息化，对医院也便于统计和整理病人数据。所以电子病历对医院和病人都有着莫大的好处，电子病历在当今社会是发展趋势。

1．  用户：

（1）       随身携带：轻便，简单。

（2）       电子钱包：预存费用，方便结算。

2．  医生：

（1）       过往病史：方便医生对症下药，对过往病史、过敏病史清楚了解。

（2）       记录病历：写入数据库，节约资源。

3．  管理员：

（1）       用户管理：用户的增加，删除，修改，查询。

（2）       余额管理：用户余额的增加与减少。

基于MT7688模块的开发笔记7——给Ubuntu系统添加samba服务

有的Ubuntu系统不能通过虚拟机的文件夹共享功能实现Windows与Ubuntu之间的文件共享,可以通过安装samba实现这个功能,主要步骤如下,供参考.经过测试,我的Ubuntu12.4.2系统已经可以实现在Windows下访问Ubuntu系统中的文件夹,当然Ubuntu12.4.2是可以通过虚拟机共享功能访问Windows中文件夹.有了这个功能后,就可以将Ubuntu中编译的文件共享到Windows. 一.更新源 [email protected]:~$ su Password: [ema

一种电子病历系统软件框架思想

袁永福 2016-5-9 电子病历系统到底采用B/S还是C/S架构是一个长期争论的话题.而在业界两种架构的应用范围谁也不占有显著优势. 在此笔者提出一种BS和CS混合的架构,以下是其原理图: 在该结构中主要部分有 WEB服务器 这是系统的核心.大多数的业务流程运行在WEB服务器中.采用ASP.NET开发,直连数据库. WEB服务器包含系统功能 API集合,以远程调用的方式向PC客户端软件提供功能支持. 还包含ASPX页面,向移动设备提供功能支持. PC机客户端 PC机客户端为一个轻量级的客户端软

电子病历，到底是用BS还是CS

袁永福 2014-8-19 前言:前几天下午去开发医疗软件的S公司,旁听了他们的内部技术讨论会议.他们目前的电子病历是B/S架构,会上一群人讨论起用C/S重构电子病历系统的可行性,于是引出了本文的题目:电子病历,到底是用B/S还是C/S. 电子病历等医疗信息化系统到底是用B/S模式还是C/S模式.这是一个长期以来困扰着许多甲方和乙方的基础性的技术问题.过去困扰了,现在还在困扰,估计将来还会困扰. 这个问题真的是可以花开两朵,各表一枝了.首先说说B/S模式. B/S模式最为称赞的特点就是部署.维护
