- Abstract:
- The Yunnan Earthquake Early Warning System used to consist of 746 sets of early warning terminals.As a result,it has a limited coverage of early warning information,and low efficiency.In order to solve this problem,we selected the internet protocol television(IPTV)as the channel for issuing the earthquake early warning information,and supported by China Mobile Yunnan Company and China Telecom Yunnan Company,we designed the Yunnan Earthquake Early Warning APK,defined the technical framework,the release rules and process,and finally developed the TV application of the Yunnan Earthquake Early Warning.So far,the application of the Yunnan Earthquake Early Warning has been pushed to about 9 million IPTV users in Yunnan province,and has been downloaded and installed by 2 million users.When an earthquake occurs,the application will soon display the warning information such as magnitude,epicenter,original time,predicted intensity arrival time of the P-wave,emergency hedging in the form of pop-up window on the TV screen.In the Yangbi MS6.4 earthquake event,the application was tested and proved to be effective.
