Description
Technical field
Present document relates to a kind of visual intelligent Decision Support Platform, especially a kind of burst biology based on Cesium technologies
Endanger visual intelligent Decision Support Platform.
Background technology
" anthrax mail " event after the U.S. " 911 " event, indicates that biohazard becomes a reality again, in economy
Under the new situation, biohazard has been not limited to biological warfare, also wraps for globalization, political multipolarization, global climate situation change
Biological terrorist, New infectious disease etc. are included to national security, social stability, economic development, environmental problem and the existence of its people
Harm is brought with health problem.
The SARS virus broken out in 2002 has swept across the whole nation or even the whole world, has seriously affected the stabilization of society, recently
Newest research results from Chinese Academy of Sciences Wuhan virus institute are shown, by researchs confirmation in 5 years, a rhinolophine in Yunnan Province
In kind of groups in contained virus stain, there is the full gene group component for the SARS virus for propagating to the mankind.This is typical prominent
The harm that object hazardous events are brought occurs, bio-safety has been classified as national security by many countries.In biohazard event
After generation, it is very necessary to take quickly and effectively emergency measure and countermeasure, and appropriate measures can make up biohazard event
Caused loss.Nowadays in terms of laboratory biological hazardous accidents disposition, more mature coping mechanism, standard have been formed,
Such as the administrative standard (CWA 15793 of American-European standard committee：2011), iso standard (ISO/WD 35001) etc. is passing on a large scale
