Abstract

The invention aims to meet the requirements on data extraction convenience and accuracy and certain compatibility for supporting data extraction, provides a scalable big data storage method for overcoming complex structure and realizes effective storage and management of engine health data. The method includes 1, acquiring engine data files; 2, according to the data files, establishing a corresponded configuration structure which contains attributes of parameters and which serves as the reference for data file analysis and subsequent data usage; 3, according to configuration structure definition, analyzing the engine data files, extracting data information of the same parameter from the engine data files to array according to time sequence, storing the data information in a binary manner as an integral block, producing corresponded parameter recording information, and generating corresponded data integral information and data recording information; 4, establishing indexes.

Description

A kind of engine health data storage means
Technical field:
The present invention belongs to engine health control technical field, relates to a kind of engine health data storage means.
Background technology:
The health management system arranged health control work completing engine of engine, comprises the collection of engine health data, storage and analysis, and wherein analytical work is the core of whole system.The analytical work of engine health control is that the mass historical data be based upon storing carries out in data mining, and the data that therefore engine is health management system arranged are stored as in order to the health management system arranged basis of engine.Engine health data derives from the real-time parameter of engine and various sensing data, has the advantages that data volume is large, data type is many, data complexity degree is high; And need that when carrying out data mining there is the requirement that data extraction is convenient, accurate, possess certain compatibility.
Summary of the invention:
The present invention is directed to the feature that data volume is large, data type is many, data complexity is high that engine health data has, for meeting needs when supported data excavates, there is the requirement that data extraction is convenient, accurate, possess certain compatibility, propose a kind of extendible large date storage method solving labyrinth, realize effective store and management of engine health data.
Technical scheme of the present invention is:
Engine health data storage means, comprises the following steps:
1) engine identification information and corresponding engine data is obtained;
2) for data file, set up corresponding configuration structure, configuration structure comprises the attribute of parameters, and this configuration structure resolves the foundation with data use from now on as data file;
3) reorganization of data and storage:
According to configuration structure definition (attribute), resolve engine data, the data message extracting same parameters from engine data arranges according to sequential, and unified for these data messages monoblock is in binary form stored, produce corresponding datalogging information, multi-group data recorded information (corresponding to multiple parameter) forms a complete data acquisition information;
4) index is set up.
Based on such scheme, the present invention is also further optimizes restriction as follows:
Step 2) attribute kit of each parameter contains positional information, sample frequency, data type/structure, the use-pattern of data, the threshold information of data of parameter in the configuration structure set up.
Step 4) index set up comprises the associating of engine identification information and data acquisition information, the associating of data acquisition information and date recorded information, the associating of data acquisition information and date configuration structure, data type/structure associate with data use-pattern.
Advantage of the present invention is:
Be configured with and support complicated data type and structure; Data Entry after storage is clear, unity of form, and disposal route is consistent; By the rapid extraction of data directory supported data.The decision operation such as fault diagnosis, trend analysis health management system arranged to whole engine provides strong supporting capacity.
Accompanying drawing illustrates:
Fig. 1 is engine health data storage means schematic diagram of the present invention.
Embodiment:
The present invention is directed to various engine health data and set up a set of configurable health data configuration structure, this configuration structure describes out the Organization of Data form of original engine health data, and custom data type and data structure can be supported, for the normalization of data storage format and use-pattern.According to this cover configuration structure according to engine, the driving time, the such hierarchical structure of data is carried out reorganizing to engine health data and is managed, be stored in database, the data of every platform engine are as one group of data, in this group, each data of driving are as a data acquisition, in this data acquisition, the total data of each parameter is integrated into a record according to sampling order sequence in binary form, set up the accumulation of corresponding data directory supported data, data are provided according to the requirement provided with the form of data acquisition or data record when data call.
As shown in Figure 1, specific implementation of the present invention is as follows:
A. engine data is obtained;
B. for data file, set up corresponding configuration structure, comprise the attribute (attribute kit contains and is not limited to positional information, sample frequency, data type/structure, the use-pattern of data, the threshold information etc. of data of this parameter) of parameters in configuration structure, this configuration resolves the foundation with data use from now on as data file;
C. the reorganization of data and storage, define according to configuration structure, resolve engine data, the data message extracting same parameters from file arranges according to sequential, and unified for these data monoblock is in binary form stored, produce corresponding reference record information, final generation corresponding data acquisition information, datalogging information;
D. set up index, comprise the associating of engine information and data acquisition information, the associating of data acquisition and datalogging information, the associating of data acquisition and data configuration information, data type/structure associate with data use-pattern.

Claims (3)

1. an engine health data storage means, comprises the following steps:
1) engine identification information and corresponding engine data is obtained;
