Data Explosion Model for Public Safety Data Processing and Its Application in a Unified Security System

In recent years, with safe city and the construction and development of the intelligent City project, has become a public security authority security control video surveillance systems, combat crime, and effective means to prevent emergency incidents. With the rapid development of network communication technology and mobile intelligent terminals (such as smart phones, tablets, etc.) the rapid proliferation of smart terminals have been carrying video surveillance, audio, speed sensors and sensing devices. Video equipment parts in high-end smart terminal can carry over parts of the lower end of video surveillance equipment. Intelligent terminal mass popularity makes building a people-centric sensing and computing networks possible in order to achieve the perfect fusion of the physical world and the digital world. Effective integration of different information spaces of information can enhance public safety and effective sensing and detection. According to public safety incidents of multi-source information fusion is proposed surge of data model, and the model is defined. And witness in one system by the model was verified. The unity of witness systems have been developed in several Beijing bus station and train station.
