【摘要】：机顶盒播控系统是一套集中式的网站管理系统,目标是将遍布在全国各个医疗计生机构的机顶盒设备进行统一的管理和控制。以前的机顶盒播控系统服务端采用MVC架构,在系统开发和运营的过程中逐渐显现一些问题,例如前后端职责耦合、无法灵活适应多应用场景需求、操作体验差等。基于JavaScript的单页应用是近几年来WEB开发领域的热门话题。一方面,单页应用相比传统的基于服务端进行页面输出的网站存在着许多优势,例如前后端解耦、易于部署和调试、操作流畅等。另一方面,随着用户终端性能的提高、JavaScript语言本身以及周边环境的发展,基于JavaScript构建大型的网站应用成为可能。基于机顶盒播控系统在当前架构和开发方式下遇到的弊端以及单页应用技术的特点和发展现状,本论文提出了将单页应用技术应用于机顶盒播控系统的构想。首先,本论文根据系统的整体需求从单页应用架构和系统功能模块两方面对系统进行了总体设计。其中,单页应用架构重点介绍了应用渲染模型、应用数据流模型以及应用状态结构,系统功能模块则从PC端站点和移动端站点两个方面进行了介绍。然后,本论文对系统组件以及PC端站点和移动端站点的主要功能模块进行了详细的设计与实现。最后,本论文从功能和性能两方面对系统进行了测试和分析。总体来说,单页应用技术的应用提高了机顶盒播控系统的开发效率并且改善了系统的操作体验。
[Abstract]:STB broadcast control system is a centralized website management system with the goal of unified management and control of set-top box equipment in various medical and family planning institutions throughout the country. The former STB broadcast control system used MVC architecture, which gradually appeared some problems in the process of system development and operation, such as the coupling between the front and back functions, the lack of flexibility to meet the needs of multi-application scenarios, the poor operation experience and so on. Single-page application based on JavaScript is a hot topic in the field of WEB development in recent years. On the one hand, the single-page application has many advantages over the traditional server-based website, such as decoupling, easy to deploy and debug, smooth operation and so on. On the other hand, with the improvement of user terminal performance and the development of JavaScript language and surrounding environment, it is possible to build large web applications based on JavaScript. Based on the disadvantages of STB broadcast control system under the current architecture and development mode, as well as the characteristics and development status of single-page application technology, this paper puts forward the idea of applying single-page application technology to STB broadcast control system. Firstly, according to the overall requirements of the system, this paper designs the system from two aspects: single page application architecture and system function module. Single page application architecture focuses on application rendering model, application data flow model and application state structure. The system function module is introduced from two aspects: PC site and mobile site. Then, the system components and the main function modules of PC and mobile stations are designed and implemented in detail. Finally, the system is tested and analyzed in terms of function and performance. In general, the application of single page application technology improves the development efficiency of set-top box broadcast control system and improves the operating experience of the system.
