Research on Data Preprocessing Technology in Safety Equipment Linkage System

摘要

Data preprocessing plays an essential role in the process of safety equipment linkage system, directly influenced the quality and the results of the later analysis and decision-making. This paper describes the process of data preprocessing in detail, and according to the characteristics of the linkage system data, proposes an improved data cleaning method in order to improve the efficiency of data preprocessing. For each log data format is different, using XML language to describe of the log data, which provides a unified interface for safety equipment linkage system data access, and then solve the problem of heterogeneous data.
