Abstract
The present invention is to meet to support to need to have data to extract requirement that is convenient, accurate, having certain compatibility when data mining, proposes a kind of expansible big data storage method for solving labyrinth, realizes effective storage and management of engine health data.Method includes the following steps: 1) obtain engine data；2) it is directed to data file, establishes corresponding configuration structure, configuration structure includes the attribute of parameters, the foundation which parses as data file and data use from now on；3) it is defined according to configuration structure, parse engine data, the data information that same parameters are extracted from engine data is arranged according to timing, and the unified monolith in binary form of these data informations is stored, corresponding reference record information is generated, corresponding data acquisition system information, datalogging information are ultimately generated；4) index is established.
Description
Technical field:
The present invention is to belong to engine health control technical field, is related to a kind of engine health data storage method.
Background technique:
The health management system arranged health control work for completing engine of engine, acquisition including engine health data,
Storage and analysis, wherein analysis work is the core of whole system.The analysis work of engine health control is built upon to depositing
The mass historical data of storage carries out in data mining, therefore the health management system arranged data storage of engine becomes engine and is good for
The basis of health management system.Engine health data derives from the real-time parameter and various sensing datas of engine, has number
According to the feature that amount is big, data type is more, data complexity degree is high；And it needs when carrying out data mining with data extraction
Requirement that is convenient, accurate, having certain compatibility.
Summary of the invention:
The feature that the data volume that the present invention has for engine health data is big, data type is more, data complexity is high,
It supports to need to have when data mining data to extract requirement that is convenient, accurate, having certain compatibility to meet, proposes one
Kind solves the expansible big data storage method of labyrinth, realizes effective storage and management of engine health data.
The technical scheme is that
Engine health data storage method, comprising the following steps:
1) engine identification information and corresponding engine data are obtained；
2) it is directed to data file, establishes corresponding configuration structure, configuration structure includes the attribute of parameters, the configuration knot
The foundation that structure is parsed as data file and data use from now on；
3) reorganization and storage of data:
(attribute) is defined according to configuration structure, engine data is parsed, is extracted from engine data same
The data information of parameter is arranged according to timing, and the unified monolith in binary form of these data informations is stored, and is generated corresponding
Datalogging information, multi-group data record information (corresponding to multiple parameters) one complete data acquisition system information of composition；
4) index is established.
Based on above scheme, the present invention also further makees following optimization and limits:
The attribute of each parameter includes location information, sample frequency, the number of parameter in the configuration structure that step 2) is established
According to the threshold information of type/structure, the usage mode of data, data.
The index that step 4) is established comprising being associated with of engine identification information and data acquisition system information, data acquisition system information and
The association of datalogging information, the association of data acquisition system information and date configuration structure, data type/structure and data user
The association of formula.
The invention has the advantages that
It is configured with and supports complicated data type and structure；Data entry after storage is clear, unity of form, processing method
Unanimously；The rapidly extracting of data is supported by data directory.The fault diagnosis health management system arranged to entire engine, trend point
The decision operations such as analysis provide strong enabling capabilities.
Detailed description of the invention:
Fig. 1 is engine health data storage method schematic diagram of the invention.
Specific embodiment:
The present invention sets up a set of configurable health data configuration structure, the configuration for various engine health datas
The data organization form of original engine health data is depicted in structure, and can support custom data type and data
Structure, the normalization for data storage format and usage mode.According to this set configuration structure according to engine, drive the time,
Hierarchical structure as data is reorganized and is managed to engine health data, is stored in database profession, and every is started
The data of machine are as one group of data, and the data driven every time in the group are as a data acquisition system, each ginseng in the data acquisition system
Several total datas is integrated into a record according to sampling order sequence in binary form, it is established that corresponding data directory branch
The accumulation for holding data provides data in data call according to the requirement of offer in the form of data acquisition system or data record.
As shown in Figure 1, specific implementation of the invention is as follows:
A. engine data is obtained；
B. it is directed to data file, establishes corresponding configuration structure, includes attribute (the attribute packet of parameters in configuration structure
Contain and is not limited to the location information of the parameter, sample frequency, data type/structure, the usage mode of data, the threshold value of data
Information etc.), the foundation which parses as data file and data use from now on；
C. the reorganization and storage of data, defines according to configuration structure, parses engine data, mentions from file
It takes the data information of same parameters to arrange according to timing, and the unified monolith in binary form of these data is stored, generate correspondence
Reference record information, ultimately generate corresponding data acquisition system information, datalogging information；
D. index is established, being associated with comprising engine information and data acquisition system information, data acquisition system and datalogging information
Association, being associated with of data acquisition system and data configuration information, data type/structure is associated with data usage mode.
Claims (1)
1. a kind of engine health data storage method, comprising the following steps:
1) engine identification information and corresponding engine data are obtained；
2) it is directed to data file, establishes corresponding configuration structure, configuration structure includes the attribute of parameters, which makees
For the foundation that data file is parsed with data use from now on；The attribute of each parameter includes the location information of parameter, sampling frequency
The threshold information of rate, data type/structure, the usage mode of data, data；
3) reorganization and storage of data:
It is defined according to configuration structure, parses engine data, the data of same parameters are extracted from engine data
Information is arranged according to timing, and the unified monolith in binary form of these data informations is stored, and generates corresponding data record letter
Breath, multi-group data record information and form a complete data acquisition system information；
4) index is established, index includes being associated with of engine identification information and data acquisition system information, data acquisition system information and date
Record the association of information, the association of data acquisition system information and date configuration structure, data type/structure and data usage mode
Association.
