安徽工业大学《物联网工程实习报告书》1实习地点：安徽祥云科技有限公司，逸夫楼机房实验室2实习内容：【1】参观马钢云计算实验室，了解运作流程，熟悉液态冷凝塔等作用，并实地探查锅炉温度监控区域，分析相关原理图；由相关技术人员指导上机进行公司架设系统的操作运行等。
【2】逸夫楼机房实验室进行系统开发课程设计，包括计时系统，校园一卡通系统等。
计时系统校园一卡通系统【1】简介：校园一卡通系统是学校内部管理人员提供具有开放性、灵活性、面向校园的应用服务管理平台。
一方面，学生和教职员工可以通过一张卡片，方便的使用校内的各种应用；另一方面，学校也可以通过一卡通系统，实现更加方便、高效的校园管理。
同时，校园一卡通系统提供了一个统一、简便、快捷的平台，进而可以与学校的各种管理信息系统无缝连接，作为信息化系统的纽带促进“数字化校园”的建设。
【2】需求分析：2-1用户分析一卡通系统的用户分为三类：1管理员：管理并授权2消费人员：持卡消费3学生和教职工：持卡使用授权服务2-2需求架构校园一卡通系统核心是所有现金、票证或需要识别身份的场合均可采用卡来完成。
从功能上来看，主要分为服务授权和消费两大功能。
2-3服务授权需求管理员具有制卡等终端权限，开放四大功能给学生和教职工使用。
2-4消费管理需求消费管理模块是系统的核心模块，它提供各种消费服务功能。
其模块用例模型如下：将卡片信息删除，被删卡将不能使用。
在本模块中，其用例模型如下：2-5实施环境需求软件环境：开发软件Microsoft Visual Studio 11.0、SQL Server Management Studio 。
硬件环境：ISO/IEC14443A标准卡、13.56MHz ISO/IEC14444A/B RFID读写器、串口线等。
2-6接口需求本系统需与13.56MHz ISO/IEC14444A/B RFID读写器连接，需要添加ISO1443DLL。
【3】硬件系统构成在IVS京胜世纪物联网仿真平台上选用14443读写器和标签，配好电源并打开串口，这里使用COM101端口：【4】软件系统开发4-1发卡功能输入合法的个人信息，保存至数据库，要获得管理员的授权示例示范：学生和教职员工消费时进行刷卡，工作人员输入消费的金额，扣除的金额保存至数据库。
4-3充值功能持卡人缴费，更改数据库中对应的金额4—4数据库设计表结构设计4—5串口调试4—6主界面初稿：【5】主要源代码：1连接数据库：namespace Utils{///<summary>///数据库操作工具/// Date:2016-09-29/// Author:Y.T.
