Research On Mobile Video Conferencing System Of Earthquake Emergency

Earthquake is a sudden and inevitable nature disaster，which will bring huge lossto people. Therefore, Taking effective emergency rescue command work isparticularly important after the earthquake. Effective emergency rescue work dependson scientific decision-making ability in the earthquake emergency. The scientificrationality of all kinds of aid decision and effectiveness of the rescue work is the keyfactor of earthquake emergency rescue work in a certain period of time. In this case,the Earthquake Command Center need an efficient real-time video conference systemto obtain the accurate site information in time, and then make detailed aid decisionsfor real-time and accurate emergency rescue service.Today, earthquake emergency video conference system based on the industry ofprivate network implementation hardware video conference system has a high cost,unable to large-scale application. And the video terminals are in fixed videoconference rooms, which is difficult to meet the real-time and efficient emergencycommand work demands in the earthquake emergency rescue. As a result, with thepopularity of tablets, smart phones, mobile devices and the application of mobilenetwork, establishing a mobile video conference system can help the earthquakeemergency rescue personnel attend the video conference system according to theexisting mobile terminal, it can improve the efficiency of emergency rescue work to agreat extent.The purpose of the subject research is that introduce the mobile video conferencesystem technology into the existing video conference system, forming an effectiveearthquake emergency mobile video conference system. At the beginning, the paperdescribed the background of earthquake lead to huge losses to make it clear that theearthquake emergency effectively emergency rescue work is very important, then itintroduced the existing earthquake emergency video conference system, analyzed itsdeficiencies, and raised the advantage of mobile video conference system, finallydetermined the content of the paper, the construction of an earthquake emergencymobile video conference system. Its technology research is based on mobile videoconference system, together with the present situation of Seismological Bureau ofSichuan province’s existing video conference system, then make sure the design ofearthquake emergency mobile video conference system, and perform detailed design, including the overall architecture of the system analysis, system cascade technologyapplication, system design and implementation of Seismological Bureau of mobilevideo conference system, and configure the network environment in the SeismologicalBureau, and test the effect of mobile video conference from two aspects, including thepoint to point video conference and multipoint video conference between testing,record video conference audio and video effects, and set up a communication networkof mobile terminal equipment, test the same mobile device’s different effect throughdifferent network connection of video conference, finally summarizes the test results.The research of this paper analyzes the shortcomings of the existing video conferencesystem in the earthquake emergency, and provides the reference for the constructionof earthquake emergency mobile video conference system of the SeismologicalBureau.
