[2019参赛作品] 【脑洞大赛】基于NB-IoT的智慧路灯监控系统(PC应用开发)

[复制链接]

作为IoT云平台的数据交互PC客户端，对平台的数据进行展示，实现本地与远程终端的数据交互，进而展现出依赖云平台的应用使用的具体场景，进一步展现云品台的优势。

1、项目结构

整个使用常规的传统的三层架构，同时引入MVVM架构模式，属于混合型架构设计，将各个层次之间实现理论解耦，提高了系统各个层次之间的独立性和可拓展性。

结构说明如下：

HandyC.HW：项目实际入口，表现层，实际用户操作逻辑的输入输出部分。

HandyC.HW.ViewModels：与表现层与之对应的视图实体类部分，对用户交互逻辑的主要实现处理模块，同时在该项目中进行相关数据实体和视图实体的相互转换工作。

HandyC.HW.Data：用于处理来自于IoT平台的数据源，为业务层提供需求的数据结果。

HandyC.HW.Service：项目的实际业务逻辑处理，组织数据层提供的数据。

HandyC.HW.Tools：项目整体结构中需要使用到的基础辅助类集合，包括网络请求相关类，缓存，数据序列化和反序列化，特殊数据格式处理等。

对应测试项目与之对应，前缀为Test.*，此处忽略

2、系统组织架构

系统组织架构分为两个大的功能模块，平台监管以及数据采集两个模块，平台监管主要是对设备实时动态进行监管，数据采集，处理来自IOT云平台的历史相关数据并展示。

3、使用技术

网络通信相关技术（数据接口请求）
WPF（UI框架）
MvvmLight（MVVM框架）
依赖注入
简单缓存
LiveCharts（图标框架）
HandyControl（WPF组件框架）
非对称双向认证（Https）
AutoMapper（DTO转换框架）

4、开发环境与工具

开发环境：Windows7 sp1、.Net Framework 4.7.2
开发语言：C#
开发工具：MicrosoftVisual Studio professional 2019（VS 2019）

5、功能介绍

设备管理页面的主页面，红框区域内为设备统计，包含了对当前设备的设备类型、设备状态、设备的协议类型的相关统计信息，属于设备总体的一个统计信息。设备列表中展示的是当前的存在的设备，以卡片的方式展示出来，包括设备的名称、设备的型号、设备的编号等预览。

显示设备的详细信息。

设备的实时数据显示页面，能够动态实时请求道IoT平台上的设备下发的最近历史信息。

云平台联动主页中的卡片为一卡片一设备，点击设备卡片，可以对设备进行联动模式控制，可支持三种联动模式，终端联控模式、自动调光模式和分段定时模式。

默认手动模式，可以通过手动直接下发指令到IoT平台，通过平台将命令通知对应的设备执行，点击控制按钮进行云平台挂载设备的开启和关闭。

用户可以通过点击切换至定时模式，设定时间后，将点击发送定时设备，等待设定的命令发送至IoT平台。

命令下发成功是接收到的反馈信息。

自动模式与手动模式的操作类似，用户通过开启和关闭实现对IoT平台上挂载的设备的执行模式的设定，关闭时，设备默认执行，为上一次的模式运行状态，开启时，变更为根据实际的自动条件进行自身状态的控制。

设备历史数据显示页面，主要功能为查询功能，用于显示从IoT平台获取到的当前设备对应的历史记录信息，可通过查询条件进行更加细致数据查找。

点击每条记录的操作列按钮，能够获取到该条记录的详细信息。

下图的页面为命令历史数据的主页面，默认显示第一个设备的相关历史数据，能够查询到多端给设备发送的相关命令指令历史信息。

通过点击每条记录末尾的数据明细，可以查看到当前命令记录的具体信息。

6、核心代码

PC端主要分为两个部分，一个是通过https请求双向认证获取到来自于IoT平台提供的相关Api接口的目标数据，将数据进行处理根据View的需求进行相关的ViewModel处理之后展示到页面中；一个是需要PC端与IoT平台上的挂载设备进行数据交互时，实现本地命令的发送，进而间接控制设备的数据响应。
