Block intelligent security big data management system

The invention relates to the technical field of big data management systems, in particular to a block smart security big data management system, which comprises the following steps: step 1, data collection: through big data analysis, new security hidden dangers can be found, the street security index can be improved, and the street security environment can be optimized; step 2, video monitoring analysis: processing and analyzing image confidence obtained by data collection through a video analysis technology; and step 3, predictive maintenance: analyzing the security data to predict an event and a reason of a security accident, so that maintenance can be carried out in advance. The system solves the problems that the inquiry work is inconvenient to realize by adopting a security guard on guard and other modes to carry out manual service, the specific positions of garbage cans, toilets and the like are inconvenient to find when the flow of people is relatively large, and when articles are lost, the monitoring
