Development Of Emergency Broadcast Alarm System Squadron Host APP

With anti-terrorism situation is increasingly grim,how fast and accurate disposal is a world problem.In Kunming and Xinjiang's violents terrorist incident have caused serious consequences.In addition to the brutality of terrorists,the slow disposal of military and police is also a problem that can't be ignored.After research and analysis,we developed a set of emergency broadcasting alarm system according to the relevant requirements of the Armed Police Force.The system is installed in the grass-roots units of the anti-terrorism units as with the armed police force.It is a complete alarm,pre-release system.The system consists of detachment host,squadron host,broadcast extension and so on.Among them,the squadron host is the core equipment of the system,which owes broadcasting alarm,pre-release and other major functions.Squadron host software takes Android operating system as the development environment,using java to develop the application.It achieves four major functions,including plan command,reporting,video command and broadcast command.The software using camera as the video source,microphone as the audio source implements the video coding and decoding based on H.264,the audio coding and decoding based on G.711.It uses Ethernet as the data transmission channel.It finally realizes that the squadron host send texts and videos to the detachment host.At the same time,squadron host broadcasts and plans the command to its subordinate broadcast extension.The system also designs a simple and easy interface.It uses modular design patterns,which can achieve high portability and expansibility.Through the functional test of the APP,the program can be a good command,reporting,video command and broadcast command,to achieve the design goal of APP,to meet the emergency broadcast alarm system and to achieve alarm,pre-release and other functions.
