【摘要】：隨著我國人民生活水平的不斷提高,收聽廣播或觀賞電視節(jié)目作為茶余飯后的主要休閑活動,落后的模擬電視和廣播與高質(zhì)量、多樣化的精神文化生活需求嚴重不匹配。國家為了解決這一矛盾而加大了發(fā)射臺站的建設力度以便有效提高偏遠地區(qū)覆蓋率。但是,近年來頻繁曝出的播出事故給社會帶來了不良的影響。如何提高廣播電視節(jié)目的播出質(zhì)量是推行新型臺站建設高標準所面臨的刻不容緩的問題。廣播電視發(fā)射臺站監(jiān)控系統(tǒng)作為解決當下問題、降低運維成本的手段應運而生,而借助監(jiān)控系統(tǒng)對分散臺站的管理模式也成為了廣電行業(yè)研究新熱點。本文根據(jù)傳輸發(fā)射系統(tǒng)特殊環(huán)境下的業(yè)務要求,采用.NET Framework作為系統(tǒng)的開發(fā)平臺來實現(xiàn)用戶需求�；贏SP.NET MVC 3和Entity Framework技術組合,以分布式緩存和MS SQL Server 2008 R2為數(shù)據(jù)交互的橋梁,將系統(tǒng)劃分為三個模塊實現(xiàn)。其中,為了實現(xiàn)多級監(jiān)控和移動辦公的要求,采用了B/S結構的設計模式,通過分布式架構布控后臺服務器、樹形式的多級聯(lián)控框架設計,合理安排各部分業(yè)務功能提高系統(tǒng)的處理效率。系統(tǒng)每個底層模塊采用獨立的組件式設計思路,通過網(wǎng)絡完成數(shù)據(jù)交互配合完成來自上層應用的業(yè)務請求。針對系統(tǒng)面臨著管理諸多不同類型的問題,在采集子系統(tǒng)設計上,有效地利用了XML配置文件的功能,以最小代價實現(xiàn)系統(tǒng)的擴展和升級。另一方面,利用HTTP服務器的特點,將數(shù)據(jù)服務視為網(wǎng)絡資源以便井然有序的管理不同角色和資源。本系統(tǒng)可用于局域網(wǎng)環(huán)境下的市或縣的監(jiān)控該中心,可獨立運行或加入多級監(jiān)控網(wǎng),集可靠性高、可擴展能力強、維護方便等諸多優(yōu)點于一身,為保證廣播電視節(jié)目安全高效播出提供強有力的支持。
[Abstract]:With the improvement of people's living standards in our country, listening to radio or watching TV programs as the main leisure activities after a meal, the backward analog television and radio and high quality, diversified spiritual and cultural life needs are seriously mismatched. In order to solve this contradiction, the country has stepped up the construction of launch stations to effectively improve the coverage of remote areas. However, in recent years, the frequent exposure of broadcast accidents to the society has brought adverse effects. How to improve the broadcasting quality of radio and television programs is an urgent problem to implement the high standard construction of new stations. As a means to solve the problem and reduce the cost of operation and maintenance, the monitoring system of radio and television transmission station emerges as the times require, and the management mode of decentralized station with the help of monitoring system has become a new research hotspot in radio and television industry. In this paper, according to the requirements of the special environment of the transmission and transmitting system, the. Net Framework is adopted as the development platform of the system to realize the user's requirements. Based on the combination of ASP.NET MVC 3 and Entity Framework, the distributed cache and MS SQL Server 2008 R2 are used as the bridge of data interaction. The system is divided into three modules. In order to realize the requirement of multilevel monitoring and mobile office, the design pattern of B / S structure is adopted. Reasonable arrangement of each part of the business functions to improve the system processing efficiency. Each bottom module of the system adopts an independent component-based design idea, and completes the data interaction through the network to complete the business request from the upper application. In order to solve the problem of managing many different types of system, the XML configuration file is utilized effectively in the design of the collection subsystem, and the system is extended and upgraded at the minimum cost. On the other hand, taking advantage of the characteristics of HTTP server, the data service is regarded as a network resource to manage different roles and resources in an orderly manner. The system can be used to monitor the center of the city or county under the local area network environment. It can run independently or join the multi-level monitoring network. It has many advantages, such as high reliability, strong extensibility, convenient maintenance and so on. In order to ensure radio and television programs safe and efficient broadcast to provide strong support.
