A Web Based Radio And Television Signal Failure Automatic Alarm System

A normal radio and television signals is the base of guaranteeing radio and TV viewers.With the development of television channels and spreading of high-definition television signal,how to ensure that the malfunction of the broadcasting and preventing TV signals from illegal spots and interference of radio and TV programs.Therefore,it is a huge challenge for staffs who are in charge of maintenance and guarantee of TV signals.The existing mode of TV signal maintenance and security in Guangxi radio and TV transmitting station is based on human,but now TV shows require more and more accuracy and stability,manual discovery and elimination of abnormal radio and television signal is very difficult.Therefore,Guangxi radio and television transmitting station urgently needs an automatic alarm system for radio and television signals.Based on the investigation of the existing radio and TV signal failure detection mode and early alarm system in Guangxi radio and TV transmitting station,we refer to the current mainstream fault detection and alarm system design concept,and propose a radio and television signal fault automatic alarm system based on web technology.Our system adopts B/S design mode,and uses the MVC framework to design three layers of system architecture,by taking the presentation layer as the interface,the system logic layer as the component and the business encapsulation module,and the.data layer as the system data pool and the data exchange storage.The automatic alarm system can use the existing internal network of Guangxi radio and television transmitting station to manage the TV signal fault detection and alarm information after entering the website of our system.The system can realize failure detection,automatic alarm,video saving and system management and other functional modules,covering the demand of radio and TV transmitting station in Guangxi for radio and TV signal fault detection and alarm.By adopting the method of software engineering program of web based radio and television signal failure automatic alarm system,the black box testing method andLoadRunner performance test tool is used to evaluate the overall system and load performance.The results show that the proposed design of radio and television signal fault detection on Web automatic alarm system can realize fault detection and alarm function based on fault detection and storage of video data in time;while the load test simulation system indicatoring our methods meet the design requirements,that imply the system can meet the demand of high load multi-user concurrent use.In the process of testing,our system has been modifying and improving by eliminating the bugs,and the final system has been running steadily and reaches the practical requirements.
