Study On Data Management And Application In EMC Integrated Test And Analysis System

The objective of the "EMC integrated test and analysis system" is to provide technical supports for identifying and eliminating potential electromagnetic interference from mutual and their own in the military equipments. The system breakthroughs in key technologies of EMC and electromagnetic environment filed test and evaluate, it can be used for EMC test and forecast of the equipments and EMC routine maintenance.This paper talks over the structure and the function of the system in detail and discusses the management and application of the data.With the demand of the system, this paper completes the designing of the database, then studys the using of the test data and the future results in the system.The paper can be devided into three parts:The first part describes the function and the structure of the system, and analyzes the types and features of the data as well as the data-flow in the system. In testing, this part discusses the relationship of the data which appear in the process of the EMC test.Then discusses the reasons and pre-treatment of the abnormal data.The second part discusses the using of the test data and the EMC prediction results.This part establishes the "Linear regression model" and "Fuzzy integrative evaluation model" to explane the application of "Regression Analysis" and "Fuzzy math" in the study of the EMC analysis.The third part design the database Management System according to the requirements.Then introduce the ideas of the designing,the structure,the relationship,the security design and the specific content of the DBMA in detail.
