Description

Technical Field

[0001] The present invention belongs to the field of power data storage, and in particular relates to a lightweight power secondary equipment data access method and system. Background Art

[0002] Power secondary equipment includes relay protection equipment, measurement and control equipment, and distribution protection and control equipment. The data of the equipment includes different types such as input, output, remote signaling, remote measurement, remote control, remote adjustment, and parameters, and the content of each type of data is different. In addition, the data structure of the same type of equipment will also change due to different service objects and application scenarios. The data of power secondary equipment needs to be stored in the memory of the device, read, displayed, and transmitted remotely through display software, communication software, etc., and tool software can also be used for debugging and configuration operations.

[0003] Due to limited storage space, the protection and control CPU of power secondary equipment cannot use database technology for data storage and access. Usually, when designing product software, various data structures are designed according to the characteristics of the service object and application scenario, and the variables of the structure are used for display, communication, configuration and other occasions. The relevant software performs data storage and read and write access according to this agreement. Because the service objects and application scenarios of each product are different, the data structure definition needs to be adjusted accordingly, resulting in different equipment software and tool software for different products, and the workload of development, testing and maintenance is huge.

[0004] For devices that cannot use databases due to limited storage space, different data structures need to be designed for different types of data. When designing product software, the structure of various types of data is designed according to the characteristics of the service object and application scenario, and the corresponding variable attributes of the structure are agreed upon when the data is displayed, communicated, and configured as a tool. The related software performs data storage and read-write access according to the agreement, which makes it impossible to effectively reuse the device software and tool software of different products; when the functional requirements of the product change and the product software is upgraded, the structure of the same type of data will also change. In some designs, compatibility processing is performed by adding spare attributes, which increases memory overhead and affects the storage read-write efficiency; the above factors lead to a large workload for product software development and testing. At the same time, because different types of equipment exist in the working environment of its service, as well as software of different periods and versions of the same product, the debugging and configuration tool software needs to start different branch programs according to the device category, and the tool software branches of the same type of equipment also need to be compatible with devices of different periods through version information, which makes the development and maintenance of tool software complicated.

[0035] Figure 1 It is a flow chart of the lightweight method for accessing data of secondary power equipment in the present invention. DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The embodiments described in this application are only some embodiments of the present invention, not all embodiments. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the protection scope of the present invention.

[0038] In view of the deficiencies of the prior art, the present invention proposes a lightweight data access method and system for secondary power equipment. By establishing a data type table, unifying the data structure header, defining the data table configuration rules, the tool software implements the display and operation of various data tables according to the data configuration rules, and converts them into data storage structures and data contents according to the data configuration rules. Define a unified data access interface for secondary power equipment software to achieve flexible access to various data variables, which are used in common modules such as communication and display processing, and are compatible with the tool software through the data table configuration rules. Realize the generalization configuration, display, operation and flexible access of various data variables, highly reuse the device common software module, and the tool software is flexibly compatible. The device software module accesses various data through a unified interface, and the compact data structure is suitable for secondary power equipment with limited storage space; the tool software simultaneously meets the flexible display, configuration and conversion of multiple types of data, and a set of tool software is suitable for different devices and different versions.

[0039] See Figure 1 As shown in the figure, the lightweight data access method for secondary power equipment disclosed by the present invention includes the following steps:

[0040] Step 1: Define all data types of the data of the secondary power equipment to form a data type table.

[0041] In a specific embodiment, the data type table is defined as:

[0042]

[0043] XML format text of the data type table:

[0044] <TlvTable name="Data Type">

[0045] <Content ID="1" tag="1" key="Boolean" name="Boolean" size="1" / >

[0046] <Content ID="2" tag="43" key="Tiny" name="Tiny Integer" size="1" / >

[0047] <Content ID="3" tag="32" key="UTiny" name="Unsigned Tiny Integer" size="1" / >

[0048] <Content ID="4" tag="33" key="Short" name="Short Integer" size="2" / >

[0049] <Content ID="5" tag="45" key="UShort" name="Unsigned Short Integer" size="2" / >

[0050] <Content ID="6" tag="2" key="Int" name="Integer" size="4" / >

[0051] <Content ID="7" tag="35" key="Uint" name="Unsigned Integer" size="4" / >

[0052] <Content ID="8" tag="36" key="Long" name="Long Integer" size="8" / >

[0053] <Content ID="9" tag="37" key="Ulong" name="Unsigned Long Integer" size="8" / >

[0054] <Content ID="10" tag="38" key="Float" name="Single-Precision Floating Point" size="4" / >

[0055] <Content ID="11" tag="39" key="Double" name="Boolean" size="8" / >

[0056] <Content ID="12" tag="8" key="OcterString" name="Octet String Type" size="8" / >

[0057] <Content ID="13" tag="4" key="String" name="String Type" size="64" / >

[0058]

[0059] Step 2: Define the structure header according to the index number, data name, data type in the data type table, data length, data quality, and data value of the secondary power equipment data.

[0060] By defining the headers of all data structures, direct and unified simple processing of all types of data is enabled. In a specific embodiment, the definition of the data structure header of the data table is as follows:

[0061]

[0062] The corresponding structure:

[0063]

[0064]

[0065] Step 3: Define the data table configuration rules in XML format. The data table configuration rules include ID, key name, column name, table width, display mode, and conversion rule.

[0066] By implementing the flexible definition of different data tables, the tool software uses a unified table processing module to adapt to different products and different types of data tables. Among them, the conversion rule transTlv corresponds to the tag field of TlvTable.

[0067] Example 1: Configuration of the input table for secondary power equipment:

[0068] <DIConfig Table="DITable" name="Input Configuration">

[0069] <Content ID="1" key="index" title="Index number" width="5" display="number" transTlv="35" / >

[0070] <Content ID="2" key="name" title="Name" width="32" display="string" transTlv="4" / >

[0071] <Content ID="3" key="datatype" title="Data type" width="9" display="list" listtable="TlvTable" transTlv="43" / >

[0072] <Content ID="4" key="datalen" title="Data length" width="5" display="number" transTlv="43" / >

[0073] <Content ID="5" key="quality" title="Quality" width="5" display="hex" transTlv="32" / >

[0074] <Content ID="6" key="value" title="Value" width="5" display="number" transTlv="1" / >

[0075] <Content ID="7" key="board" title="Board Card Number" width="5" display="number" transTlv="32" / >

[0076] <Content ID="8" key="order" title="Input Number" width="5" display="number" transTlv="32" / >

[0077]

[0078] Example 2: Remote Control Meter Configuration for Secondary Electrical Equipment:

[0079] <CtrlConfig Table="CtrlTable" name="Remote Control Configuration">

[0080] <Content ID="1" key="index" title="Index Number" width="5" display="number" transTlv="35" / >

[0081] <Content ID="2" key="name" title="Name" width="32" display="string" transTlv="4" / >

[0082] <Content ID="3" key="datatype" title="Data Type" width="9" display="list" listtable="TlvTable" transTlv="43" / >

[0083] <Content ID="4" key="datalen" title="Data Length" width="5" display="number" transTlv="43" / >

[0084] <Content ID="5" key="quality" title="Quality" width="5" display="hex" transTlv="32" / >

[0085] <Content ID="6" key="value" title="Value" width="5" display="number" transTlv="1" / >

[0086] <Content ID="7" key="board" title="Control Point Writing" width="5" display="number" transTlv="32" / >

[0087]

[0088] Step 4: Based on the data table configuration rules, perform the display and configuration operations of the data table in the tool software.

[0089] In Example 1, the input configuration table is displayed as:

[0090]

[0091] In Example 2, the remote control configuration table is displayed as:

[0092]

[0093] Step 5: Based on the data table configuration rules and the defined structure header, generate the structure and corresponding data in the tool software.

[0094] According to the conversion rule transTlv in the data table configuration rules, the corresponding structure is automatically formed, and the values in the table are converted into structure data, enabling the tool to flexibly be compatible with different products and different types of data, and automatically converting them into a data structure and its values consistent with the device, without the need for secondary processing in the device.

[0095] In Example 1, according to the transTlv in DIConfig, it is converted into the input configuration data storage structure:

[0096]

[0097] In Example 1, the table is converted into the input table structure data and downloaded as the corresponding input table configuration data in the device:

[0098]

[0099] In Example 2, according to the transTlv in CtrlConfig, it is converted into the remote control configuration data storage structure:

[0100]

[0101]

[0102] In Example 2, the table is converted into the input table structure data and downloaded as the corresponding input table configuration data in the device:

[0103]

[0104] Step 6: Define a unified data access interface to read the data value according to the index number, data type or data length in the structure.

[0105] The first five attributes of the structure tTableHead of different tables are the same. The sixth attribute value corresponds to the data type according to datatype, and its storage space size is allocated according to datalen; therefore, the communication, display and other functions in the power secondary equipment can access the names and values ​​of different types of data through the same interface;

[0106] The structure header definition of different products and different types of data is the same. The public software modules such as communication and display can correctly access the data through the data access interface, reuse the public module code, and do not need to modify the code. This step makes the public software modules such as communication and display of the device universally designed, adapting to the data type and configuration of different versions, and does not need to modify the public software modules due to different service objects and application scenarios of the products.

[0107] Step 7: Based on the data access interface, use the communication software of the power secondary equipment to access different data values ​​according to the data type, which is used for communication between the equipment and the monitoring system, or transmitted to the debugging tool for dynamic display of numerical values.

[0108] Step 8: Based on the data access interface, the display software of the power secondary device is used to access the data name and data value according to the data type, so as to display the current device data locally.

[0109] In Example 1, the local display of the input table is:

[0110]

[0111] In Example 2, the remote control meter local display is:

[0112]

[0113] The beneficial effect of the present invention is that, compared with the prior art, the present invention provides a lightweight method and system for accessing data of secondary power equipment, and the common software modules of the equipment are highly reused; the common software modules of the equipment such as communication and display are of universal design, and are adapted to configurations that are not affected by data types or different versions; the common software modules are not modified due to different products, different service objects, and different application scenarios; the compact data structure is suitable for secondary power equipment with limited storage space; the lightweight structured data saves the memory resources of the equipment and has a higher data processing speed; various data tables automatically generate data structures in the equipment and corresponding parameters through conversion rules; the equipment directly uses the data converted by the tool according to the structure without further processing; the designed tool software can simultaneously meet the flexible display, configuration, and conversion of multiple types of data, and a set of tool software is adapted to different equipment and different versions.
