1、Introduction The probability of public crisis and accidents around the world is increasing quickly in the past several years i.e. H1N1, Ebola and Typhoon Haiyan. Emergencies with severe effect like the Explosion of Tianjin Port also lead a huge fluctuation of online opinion in China. The increment and spread of web user makes the web becomes a major role in the information propagation. The evolution of online opinion about emergencies has become a vital factor in the management of crisis for our government .

5、Conclusion 1）In this paper, we proposed a new CPS Model based Online Opinion Governance system which constructed on cellphone APP for data collection and decision make in the back end. And based on the online opinion data we collected, we also proposed the graded risk classification method and accident classification method. 2）Based on the risk classification method, we have built an efficient CPS Model based simulated emergency accident replying and handling system. It has been proved in analysis of 2015 Tianjin Explode accident.
