The Reconstruction Project Of Chengdu Radio Broadcasting Live System

As one of the most important part of communication engineering,broadcasting and TV engineering are not only providing more colorful things for people,but also the key of the development of our society and the technology.Because of those media,we have widened our horizons of the whole world.Chengdu Broadcasting and TV Station decided to reconstruct the audio broadcasting system.Because with the development of technology,people have more strict requirements of sound quality.Analog and digital signal transferring technology were widely used in transferring audio program signals before.But this situation has been changed.Engineers have researched new technologies,which is AoIP(Audio over IP).We are transferring audio signals through the Internet.The first chapter mainly describes the development of audio technology.It also focuses on the application of audio technology and the development and application of Dante technology.The second chapter introduces the technical equipment reconstruction project of Chengdu Radio Station: it focuses on the installation of the peripheral equipment of the mixer,the debugging of the mixer module AoIP technology,the installation and commissioning of the server,and the debugs of the integration of the system installation.Systematic analysis and research on problems that occur during the installation and installation of equipment.And give corresponding solutions.The third chapter systematically summarizes the technical equipment reconstruction project of Chengdu Radio Station.The main conclusions obtained are as follows:1.The new system is more in line with the development trend of the audio technology industry,that is,gradually reducing the use of common analog and digital XLR line types and interfaces,and using more efficient transmission methods,using more IP audio transmission methods,or a combination of the both,transmitting more channels,higher quality audio signals;2.The main equipment is more powerful,and enhances the image of radio stations;3.The peripheral equipment is updated,the old recorders and CD players are eliminated,and the IPAD,Bluetooth player and webcast live software that are more popular among young people are added to break the stereotype of the original radio station,which is more in line with the trend of the times;4.The total number of wires is reduced,and the wiring of the equipment room is cleaner and tidy.5.Through commissioning and trial operation,the following emergency solutions have been added to the technical equipment retrofit installation project: 1.PoE(Power of Ethernet)replaces the switch for network cable power supply;2.Expands the virtual fader,and uses the emergency switcher to be the broadcasting signal backup when the crash occurs;3.Develop Linux system patches to fundamentally solve the crash problem;4.Strictly train the technicians' fault handling ability.The ability to control broadcast stability and respond to the risk of crash is greatly enhanced.Guarantee the safety and stability of the broadcast.
