Problems solved by technology

[0003] At present, the following problems exist in the data collection-monitoring-processing-analysis process of my country's attitude and orbit control engine test data: (1) The test data storage and management are scattered, and the data in different periods are recorded in different computers, instruments and equipment or CD-ROM carriers In fact, it has caused difficulties in data retrieval, reuse, and data sharing; (2) The testers rely on experience and manual data sorting for data analysis and zeroing, which is highly dependent on the knowledge structure of the testers; in multi-model and multi-task Under the parallel development mode, the verification of the data analysis model relying on a small number of experts hinders the efficiency of the test process and increases the probability of human error

Embodiment Construction

[0014] The present invention is a system and method for engine historical data management and analysis, specifically displays various test data information in the form of tree nodes, charts, curves and data on the browser, and realizes self-service analysis and analysis of test data on the browser interface. Management, the whole system mainly solves the layered display of high-definition base map, multiple data comparison and data curve display, data management and analysis calculation, etc. The rapid display of test data in B / S mode is realized by Ajax's partial screen refresh technology. Using the Struts architecture technology based on MVC mode to ensure the realization of page navigation, program logic and other functions. The controller of Struts, Action Servlet handles the request of the test data user, and uses the configured Action Mapping object to map the request to the Action processor object for processing. Then the Model Action object of Struts accesses the data...

Abstract

The invention provides an engine history data management and analysis system and method. The system and method have good generality and feasibility and can provide users with more general historical data retrieval, management and analysis services, such as free addition of historical model data, free extraction of different batch tests for data comparison and statistical calculations. The method includes the following steps of 1, establishment of historical data templates; 2, building of a data management and analysis platform; 3, analysis and import of historical data; 4, analysis of the data.

Description

technical field [0001] The invention is mainly used in the field of data management and analysis technology of attitude and orbit control engines. Background technique [0002] The test data is an important result of the attitude-orbit control engine test. Data analysis is important for checking whether the purpose of the test is achieved and whether any abnormal conditions are exposed. Accurate acquisition and in-depth analysis of test data are important for evaluating engine performance, analyzing failure causes, and formulating engine improvement plans. are of great significance. The data analysis link is a powerful tool to improve data validity and abnormal data diagnosis. It can not only analyze obvious faults (sensor abnormalities, etc.) Data management and analysis technology research can provide technical means for data anomaly analysis and effectiveness evaluation. [0003] At present, the following problems exist in the data collection-monitoring-processing-analy...
