qt mysql药品订购系统_基于RFID,QT,MYSQL开发的医疗电子病历系统

迷南。 2023-01-11 08:28 101阅读 0赞

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。
