【摘要】：现今,越来越多的应用和服务需要与来自现实世界中的感知设备进行实时信息交互,越来越多的企业已经开始使用以物联网为标志的新一代信息技术。随着物联网用户的日益增长,现有的组态软件无法完全满足层出不穷的用户需求。例如,普通的组态软件只提供二维视图,然而,在许多行业中,用户希望能查看到更真实的三维场景;其次,普通组态软件的各个服务之间独立,而如果将多个服务通过规范操作相互关联,就能组合成一个新的服务供项目使用;再者,在查看组合系统的视图前,用户往往需要安装配置该软件的客户端,而部分用户只负责监视系统示意图,并不需要该软件的全部功能。由此可见,普通的组态软件具有一定的局限性。为此,本论文依据实验室工程项目,以供暖行业为例,提出了一种支持服务组合的组态系统,该系统提供二维与三维的可视化设计和运行功能,便捷的网络监视和控制功能,同时通过服务组合提供多样化的服务来满足不同用户的展示需求。系统主要包含两个模块,绘图模块和展示模块。绘图模块在开源软件Jgraphx和SweetHome 3D的基础上进行功能扩展,展示模块根据W3C Widgets标准封装了Widget,用来提供服务。本系统能满足不同行业、不同用户层次的多方面需求,其中,绘图模块提供基于服务组合的组态软件功能,工程设备编辑人员可用来绘制二维SVG和三维OBJ模型图,为展示模块提供接口。系统展示模块基于B/S架构,其服务组合平台为工程设备查看人员提供监测功能,不但有动画效果,而且实时显示与传感器绑定的数据,此外具有权限的人员还可以对组件进行控制,包括单个遥控、定时遥控和成组遥控。论文还对本系统进行了详细测试,验证了各个模块的功能。最后,本文对整体工作进行总结并指出了目前存在的不足之处。
[Abstract]:Nowadays, more and more applications and services need real-time information interaction with perceived devices from the real world. More and more enterprises have begun to use a new generation of information technology marked by the Internet of things. With the growing number of Internet of things users, the existing configuration software can not completely meet the endless demand of users. For example, normal configuration software provides only two-dimensional views, however, in many industries, users want to see a more realistic 3D view; second, common configuration software services are independent of each other. If multiple services are associated with each other through canonical operations, they can be combined into a new service for the project to use; moreover, users often need to install a client that configures the software before viewing the view of the composite system. Some users are only responsible for monitoring the system schematics and do not need the full functionality of the software. Thus, the common configuration software has some limitations. Therefore, according to the laboratory project and taking the heating industry as an example, this paper presents a configuration system that supports the combination of services. The system provides two and three dimensional visual design and operation functions, and convenient network monitoring and control functions. At the same time, through the service composition to provide a variety of services to meet the display needs of different users. The system mainly consists of two modules, drawing module and display module. The drawing module is extended on the basis of open source software Jgraphx and SweetHome 3D. The display module encapsulates Widgetaccording to W3C Widgets standard to provide service. The system can meet the needs of different industries and different user levels. Among them, the drawing module provides the function of configuration software based on service combination, and the engineering equipment editor can use it to draw 2D SVG and 3D OBJ model. Provides the interface for the display module. The system display module is based on the B / S architecture, and its service combination platform provides the monitoring function for the engineering equipment viewer. It not only has animation effect, but also displays the data bound to the sensor in real time. In addition, the authorized personnel can control the components, including single remote control, timing remote control and group remote control. The system is tested in detail and the function of each module is verified. Finally, this paper summarizes the whole work and points out the shortcomings.
