The invention belongs to the technical field of data processing, and discloses a terminal-based big data analysis processing method and system. The terminal-based big data analysis processing system comprises a data acquisition module, a data preprocessing module, an authority management module, a wireless signal transmission module, a central processing and control module, a data interaction module, a network server module, a security detection module, a warning module, a local storage module and a man-machine interaction module. According to the invention, data acquisition is carried out through the data acquisition module, the acquired data information is transmitted to the data analysis and processing module, and the security of the data is detected through the security detection module, so invasion of dangerous data can be effectively avoided; the configuration files are correspondingly set in advance according to the attributes of the to-be-processed data, the configuration files corresponding to the to-be-processed data with the same attributes are the same, and the corresponding relation between each step of the preprocessing process and the program is established, so that the workload and the error rate are reduced, and the analysis processing efficiency of the data is improved.
