The invention provides a personal health life big data collection and analysis system. The system comprises a health data collection node, an intelligent node health data collection module, a cloud server, an adaptive multi-network health data access module, a health big data analysis and processing module and a client. The system is advantaged in that a high-universality big data collection and analysis platform in the distributed cluster environment is established, big data analysis efficiency and accuracy are improved through unified format data sets and effective streamlining mechanisms, ahealth event database with the FP tree data structure is established, the evolutionary status of the health condition of a user at a particular stage can be presented, connections and laws of the health condition of the user can be reflected, result cluster sorting is carried out from frequent item sets extracted from the FP tree, the health event status of the user is classified into a specifictype, based on the classification result of outputted by the system, targeted treatment and nursing strategies can be implemented.
