Design And Implementation Of Center Audio Matrix Master Software System

Nowadays, with the accelerative deepen of digitization and network in broadcaststations, the central audio matrix system, which is the most important datatransmitting,control and exchange system, has been applied widely in broadcaststations and played a keyrole. As the most important part of the system, matrix controlsystem has beenimpacted on the normal works of the audio matrix directly; itsreliability is also a crucial factor of the system. The stability,functionality andhandleablity is very important to central audio matrix.The design process of embedded audio matrix software part and PC controlprogram is discussed in this paper. With C, C++and Scripting language, we realized ahigh stability, high reliability and high extension center audio matrix system.Firstly, wediscussed the practical application environment of the industry of broadcast station, therequirement proposed by this environment to the audio matrix and the characteristic ofthe audio matrix which is base on this environment. Then introduce applicationprogram of ARM realized by c language, such as detailed analysis, modules andrealized. Then introduce PC control program, including the requirement analysis, theframework design, function module partition and the realization of the modules. Finallyin order to facilitate the software of the commissioning, detailed introduces therealization of the virtual test environment, including virtual environment functionanalysis, design and implementation according to the function demand virtual hardwareprocess, hardware parameters set interface implementation, virtual test environmentplay a important role in the commissioning stage.The new generation of the audio matrix control system researched in this paper hashigh reliability, high availability and high expansion ability. In addition,use hard diskstorage log and command execute information and use two main card. One main card is master card and another is slave main card, master card and slave card synchronouscommunication with serial interface, slave card instead of master card when mastercard error and this action will not affect the operation that has completed before.
