Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

A first embodiment of the present invention relates to a data management method including the steps of: according to the operation information of the user, determining elements corresponding to the operation information in a predefined data model for managing the airborne data; if the corresponding element is a simple element, acquiring data input by a user; updating the value of the corresponding element according to the data; wherein the simple element is an element without a child element in the data model. In this embodiment, the element selected by the user is displayed according to the association relationship between the operation information of the user and each element specified in the predefined data model. The user can manage the airborne data only by inputting the relevant data of the elements, and the user does not need to write codes, so that the management cost of the airborne data is reduced. The data model is a predefined model, and a user cannot change the model structure, so that the reliability of data definition is improved, and the reliability, maintainability, testability, safety and guarantee of the aircraft are improved.

The implementation details of the data management method of the present embodiment are exemplified below. The following is merely an implementation detail provided for ease of understanding and is not necessary to practice the present embodiments.

The data management method in the embodiment can be applied to single-ended electronic equipment, and the electronic equipment can be a terminal, a server, a cloud server and the like. The data management method can also be applied to an onboard data management platform. The user logs in the airborne data management platform through a webpage or a client of the terminal. And the airborne data management platform is communicated with the terminal to acquire the operation information of the user in the webpage or the client so as to execute the data management method. As shown in fig. 1, the method specifically comprises the following steps:

step 101: and determining elements corresponding to the operation information in a predefined data model for managing the airborne data according to the operation information of the user.

Specifically, the operation information of the user indicates an element control triggered by the user at the operation interface. The element controls of the operation interface are in one-to-one correspondence with elements in the data model. When a user triggers an element control, determining an element corresponding to the element control in the data model according to the corresponding relation. The airborne data may be airborne health management data, or other data, which is not limited in this embodiment.

In one example, the electronic device presents the data model in a tree structure in an operation interface of a user according to a predefined data model for managing the recorded data, and elements in the data model are presented in the form of element controls, wherein names of the element controls are names of corresponding elements.

Alternatively, when the data management method is applied to the airborne data management platform, the data model can be respectively constructed for each entity.

Alternatively, the data model is a data model defined based on extensible markup language structure XML schema technology. Specifically, the XML Schema technique is a language that expresses XML document rules. The data model is defined using an XML document structure based on an XML Schema definition (XML Schema Definition, XSD). For example, a top class is defined in the data model, such as a member data class (MemberData), from which each subclass is derived; and establishing an association relation between the parent class and the child class through names (names) and references (ref) in an XML Schema technology.

It is worth mentioning that the data model is defined by the XML Schema technology, so that the data model exists in the form of an XML file, and the use is more convenient.

In one example, a schematic diagram of a partial data model is shown in FIG. 2. In this partial data model, the root element is member data (MemberData) 201. The member data 201 has one subelement, namely member model data (memberModelData) 202. The membership model data 202 has two sub-elements, namely status message 203 and fault report 204 (faultereport). The status information 203 has a sub-element, namely, binding items (bindditems) 205. The fault report 204 has two subelements, namely fault report data (faulteeportdata) 206 and initiation test (initedtest) 207. The XML file corresponding to the partial data model is represented as follows:

<xs:element name="MemberData">

<xs:complexType>

<xs:sequence>

…

<xs:element ref="MemberModelData"/>

<xs:element ref="xxxData"/>

…

</xs:sequence>

…

</xs:complexType>

</xs:element>

<xs:element name="MemberModelData">

<xs:complexType>

<xs:sequence>

…

<xs:element ref="StatusMessage"/>

<xs:element ref="FaultReport"/>

…

</xs:sequence>

</xs:complexType>

</xs:element>

<xs:element name="StatusMessage">

<xs:complexType>

<xs:sequence>

<xs:element ref="BindedItems"/>

</xs:sequence>

…

</xs:complexType>

</xs:element>

<xs:element name="FaultReport">

<xs:complexType>

<xs:sequence>

<xs:sequence minOccurs="0">

<xs:element ref="FaultReportData"/>

<xs:element ref="InitiatedTest"/>

…

</xs:sequence>

…

</xs:sequence>

…

</xs:complexType>

</xs:element>

wherein < xs: element name= "a" > represents creating an element named "a" in the data model, < xs: complexType > represents that the element is a complex element, sequence in < xs: sequence > is an indicator, representing that the elements between two < xs: sequences > appear in the order of being declared, < xs: element ref= "B"/> represents that the element corresponding to the declaration where the statement is located has a subelement named "B", and < xs: element > represents that the declaration ends. Sequence minOccurs = "0" > is a < minOccurs > indicator, indicating that the minimum number of times its corresponding element can appear is 0.Member data, member Modeldata, xxxData, status message, faultReport, binddItems, faultReport data, and InitiatedTest are defined element names.

From the above, the data model can be defined by XML Schema technology, the association of each element in the data model is established, and the data definition mode is specified.

It should be noted that, as will be understood by those skilled in the art, in practical application, the number of elements in the data model may be set according to needs, and the present embodiment is not limited.

Alternatively, the data model is stored in the database in the form of an Entity-Attribute-Value (EAV) based model. Specifically, the data model defined based on the XML Schema technology exists in the form of an XML file. The XML file defines all element information of the on-board health management data, such as Name, identity (Id), switch Port (Port), etc. Storing all possible attributes into an Attribute (Attribute) table, analyzing an XML file, sequentially reading Attribute values according to a structure, storing the values into an Entity (Entity) table and a Value (Value) table, and correlating data in the Value table and the Attribute table according to the attributes.

In one example, the electronic device first creates an Entity table, an Attribute table, and a Value table, and establishes an association relationship between the tables. And analyzing the XML file corresponding to the data model, and storing the XML file into a database corresponding table based on the EAV model.

It is worth mentioning that the created data model is saved through the database model, namely the EAV model, so that the attribute can be dynamically added or removed for the data model, the data model is saved in the form of a database, and the data model structure is more intuitively displayed.

Step 102: if the corresponding element is a simple element, acquiring data input by a user; and updating the value of the corresponding element according to the data.

Specifically, a simple element is an element without a child element. When a user clicks on an element without a child element, the element may be assigned a value. Wherein assigning a value to the element is understood to mean determining the definition of the element based on data entered by the user. For example, assigning an element of the fault equation based on data entered by a user means: based on the data entered by the user, the definition of the fault equation, i.e. the actual logical expression of the fault equation, is determined.

In one example, after updating the corresponding element, the on-board data is managed according to the updated data model.

Alternatively, if the corresponding element is a complex element, displaying sub-elements of the corresponding element according to the data model; the complex element is an element having sub-elements.

In one example, the data includes a logic circuit diagram or imported form. Specifically, when the element clicked by the user is a simple element, the element can be assigned by importing a form or editing a logic circuit diagram.

It is worth mentioning that the assignment is performed through the logic circuit diagram definition mode, so that a user can perform data definition without learning XML language, and the operation difficulty of the user is reduced.

For example, if the data is a logic circuit diagram, the process of updating the values of the corresponding elements according to the data includes: identifying a logic circuit diagram; generating a logic expression according to the identification result; the logical expression is taken as the value of the corresponding element. Specifically, the electronic device may determine a logic expression corresponding to the logic circuit diagram by identifying each object in the circuit diagram according to a definition of each object and a connection relationship between ports of each object.

In one example, after the logical expression is generated, validity of the logical expression is checked, and if it is determined that the logical expression passes the check, a step of taking the logical expression as a value of a corresponding element is performed, and if the logical expression does not pass the check, a user may be notified by means of an alarm or the like.

For another example, if the data is a form, the process of updating the value of the corresponding element includes: the form is parsed, and the data in the form is used as the value of the corresponding element.

Alternatively, the form may be a form edited by the user, or may be a form template of the element downloaded by the user from the airborne data management platform, where the form template is edited to obtain the form.

It should be noted that, as those skilled in the art will understand, the forms may be obtained by other methods, and the present embodiment is not limited to the source of the forms.

Optionally, before acquiring the data input by the user, the data management method further includes: ejecting an editing window corresponding to the element; the editing window is a lead-in window or a drawing window, and logic components are displayed in the drawing window so that a user can construct a logic circuit diagram in the drawing window based on the logic components. Specifically, when the data model is constructed, a developer sets up a data definition mode of each element in advance. When a user clicks an element control corresponding to an element, a corresponding editing window is popped up according to a set data definition mode of the element, so that the user edits in the editing window to obtain the value of the element.

It is worth mentioning that the data management service is provided for the user based on the operation interface and the database, and the visual operation environment is provided for the user, so that the user operation is simpler and more convenient.

For example, a message sent by the system G contains the signal 1 (DP 1) and the signal 2 (DP 2), and is evaluated and presumed to belong to the fault message when the values of DP1 and DP2 are both 1. For this failure, in this embodiment, the user may define such a failure in a visual manner. Firstly, the electronic device displays the XML file structure (namely, the data model) of each system according to the tree structure, then selects DP1 and DP2 under the system G, takes DP1 and DP2 as two input signals, and connects the two signals with an AND gate in the form of a logic circuit, as shown in figure 3, which shows that the message is a fault message when DP1 and DP2 are both true.

It should be noted that the above data types are only illustrative, and in practical application, other types of data may be obtained, that is, the user may input data in other ways, which is not limited in this embodiment.

In one example, the code for defining the logical expression is as follows:

definition logic expression

class ExpFrontHelper {

Creating gson (Java class library to map between Java objects and JSON data) instances

public static Gson gson = new GsonBuilder().disableHtmlEscaping().create();

Method for converting/object to JSON

public static String toJson(Object obj) {

return gson.toJson(obj);

}

The logical relationship is/are acquired

public static String getSymbol(String category) {

If the relation is not, returning the character to be

if ("not".equalsIgnoreCase(category)) {

return "~";

}

If the AND relationship, return the "& &

else if ("and".equalsIgnoreCase(category)) {

return "&&";

}

If the OR relationship, return the character "|"

else if ("or".equalsIgnoreCase(category)) {

return "||";

}

else if ("geq".equalsIgnoreCase(category)) {

...;

}

return null;

}

Expression validity check

...

Expression of// generation

...

Memory expression

...

The code for detecting the validity of the expression, the code for generating the logic expression and the code for storing the expression can be written according to the requirement of the project, and the details are not described here.

In one example, the inventors have tested this data management method. In the test process, the programming environment is an integrated environment (IntelliJ IDEA) developed by a Java programming language, and the version of the Java virtual machine is 1.8. In the experimental running environment, the memory is 32GB, and the operating system is Windows 10 family edition. The data set of the trial is from a portion of the basic health management data collected by the domestic aircraft. Basic airborne data can be successfully collected through a defined data model of the airborne data, and a certain message sent under the left wing system is subjected to fault definition. Through testing, under the condition that the fault definition is met, the health monitoring system of the left wing successfully reports the fault to the airborne maintenance system. Under the definition and management method of the airborne health data, the management cost of the airborne data is greatly reduced.

The foregoing is merely illustrative, and is not intended to limit the technical aspects of the present invention.

Compared with the prior art, the data management method provided in the embodiment displays the elements selected by the user according to the association relationship between the operation information of the user and the elements specified in the predefined data model. The user can manage the airborne data only by inputting the relevant data of the elements, and the user does not need to write codes, so that the management cost of the airborne data is reduced. The data model is a predefined model, and a user cannot change the model structure, so that the reliability of data definition is improved, the onboard data management process is more efficient and safer, and the reliability, maintainability, testability, safety and assurance of the aircraft are improved.

A second embodiment of the present invention relates to a data management method. The embodiment is further improved on the basis of the first embodiment, and the specific improvement is that: when the data management method is applied to an onboard data management platform, other relevant steps are added before and after the step of updating the values of the corresponding elements according to the data.

Specifically, as shown in fig. 4, the present embodiment includes steps 401 to 404, wherein

steps

401 and 403 are substantially the same as

steps

101 and 102 in the first embodiment, and are not described herein. The differences are mainly described below:

step 401: and determining elements corresponding to the operation information in a predefined data model for managing the airborne data according to the operation information of the user.

Step 402: the corresponding element is locked.

In particular, since the on-board data management platform can log in for multiple users, elements operated by the users are locked before editing the data.

It is worth mentioning that the airborne data management platform provides airborne data management service for multiple users, and the elements are locked before editing the data of the elements, so that the problem of system errors caused by the fact that multiple users edit one data at the same time can be avoided, and the reliability of the airborne data management platform in a multi-user cooperation mode is improved.

In one example, before determining elements corresponding to the operation information in a predefined data model for managing the on-board data according to the operation information of the user, the electronic device determines that the user has management rights according to login information of the user and pre-stored management rights information. Specifically, when the user has the management right, the user can edit the values of the elements of the data model, so that the safety of the data is ensured.

Step 403: if the corresponding element is a simple element, acquiring data input by a user; and updating the value of the corresponding element according to the data.

Step 403: unlocking the corresponding element.

Specifically, when the user exits editing, the element is unlocked so that other users can access or modify the data of the element.

Compared with the prior art, the data management method provided in the embodiment displays the elements selected by the user according to the association relationship between the operation information of the user and the elements specified in the predefined data model. The user can manage the airborne data only by inputting the relevant data of the elements, and the user does not need to write codes, so that the management cost of the airborne data is reduced. The data model is a predefined model, and a user cannot change the model structure, so that the reliability of data definition is improved, and the reliability, maintainability, testability, safety and guarantee of the aircraft are improved. In addition, the edited element is locked, so that the problem of system errors caused by simultaneous editing of the same data by multiple users can be avoided.

The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
