Abstract: Based on the characteristics of the early warning and detection system business application, an architecture of distributed early warning detection big data platform is proposed. With the concept of big data as the core, the technical architecture, data architecture and operation mode of distributed early warning detection big data platform system are designed. And the key technologies needs to realize the system architecture are explored and analyzed. The application of big data techniques will be of great significance to improve the data processing ability and decision support ability of early warning and detection information system.
