The Application And Research On Multi Party Call Technology In Rescue Communication

With the rapid development of network and multimedia communication,IP network has gradually interacted with telecommunications,television and other media.Among them,multi-party communication technology supported by IP network has also made great strides forward.The technology is currently being used in many areas and can significant ly improve operational efficiency.Therefore,for mine rescue communication,it is very necessary to explore the mine disaster site through multi-party communication technology,realize the barrier-free communication connection between the underground and the out-of-well operation control system,thereby increasing the efficiency of rescue.In this paper,for the actual requirement that the conventional multi-party communication mode is difficult to play an effective role in mine rescue work,a multi-party communication platform supported by Vo IP is established.In this study,the Win C E 6.0 manipulation environment and S3C6410 microprocessor are selected specially to realize the construction of software and hardware system.At the same time,referring to the core content of multi-party calls,starting from the specific application of multi-party calls in rescue communication platform,VS2005 is selected as the development background and the multi-party communication platform is established.At the same time,echo cancellation is used to improve the overall quality of multi-party calls,and mixing is used to enable multi-party to communicate at the same time.After the successful establishment of the multi-party communication platform,the following test work is planned,and the corresponding detection system is constructed to test the performance of the platform.After testing,the platform can effectively play the role of multi-party calls,improve the quality of communication,in addition,it also shows that the platform can play a role in mine rescue work,with high practical value..
