Description

Technical Field

[0001] The present invention relates to the field of terminal technology, and in particular to a method for creating a data dictionary, a terminal device, and a medium. Background Art

[0002] At present, hydrogen fuel cells have become a hot field of research in the field of new energy at home and abroad due to their advantages such as high efficiency, zero emissions, short refueling time and long driving range.

[0003] For hydrogen-fired power control systems, many key components are coordinated and controlled as a whole through the controller area network (CAN) (also known as the CAN communication network). The effectiveness of the advantages of hydrogen-fired power control systems and the achievement of key indicators are closely related to the control functions of the hydrogen-fired power controller. The control of the hydrogen-fired power controller is completed by three parts: upper-layer application control, lower-layer driver control, and upper-layer and lower-layer integration. However, when the hydrogen-fired power control system completes the scheduling of the upper-layer application to the lower-layer driver, during the construction of the simulation model (such as Simulink), there are a large number of control variables in the upper and lower layers. These control variables are implemented by the Simulink Data Dictionary module.

[0004] However, in practice, it has been found that the data dictionary corresponding to the control variables is currently created manually in the Simulink DataDictionary module.

[0045] In the process of filing this application, the applicant also discovered that a large number of control variables in the upper and lower layer integration of the currently known hydrogen fuel cell control system, such as the upper and lower layer integration variable Simulink Signal (signal line information) and calibration observation quantity Simulink Parameter (parameter information), are all manually established in the Simulink DataDictionary module. Figure 1A schematic diagram showing the creation of a data dictionary in the prior art is shown. Figure 1 In the Simulink Model Explorer, users first open the house model's resource manager (specifically, the Simulink Model Explorer). Then, they add control variable types, such as variable information (MTALAB Variable), parameter information (Simulink Parameter), two-dimensional lookup table information (SimulinkLookupTable function), and signal line indication information (Simulink Signal). Then, they define the properties of the variable types they want to add. After completing the information, they save the newly added variable types.

[0046] However, in practice, it was found that the hydrogen-fired power control system involves nearly 2,000 control variables. Manually completing this project work requires a lot of time and energy, and the work efficiency is low, errors are prone to occur, error correction is difficult, and debugging takes a long time.

[0047] The embodiments of the present application provide a method for creating a data dictionary, thereby solving the technical problems of low efficiency and low accuracy in the prior art of manually creating a data dictionary.

[0048] The technical solution of the embodiment of the present application is to solve the above-mentioned technical problems. The overall idea is as follows: obtain the control variable information in the hydrogen-fired power control system; construct dictionary basic information for the control variable information to obtain corresponding dictionary basic information; use programming technology to create a corresponding data dictionary for the hydrogen-fired power control system based on the dictionary basic information.

[0049] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0050] First, the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0051] In order to solve the problem of manual creation of a large number of control variables in the integration of upper and lower control layers of a hydrogen-fired power control system, this application adopts programming technology / means to realize the rapid creation of control variables in the data dictionary (DataDictionary) of a simulation model (Simulink). The technical principle adopted by this application is: the data dictionary in Simulink is a persistent repository for storing Simulink model-related data. The function of the data dictionary DataDictionary is to store all data objects used by a model in one place for management. Data objects include signal objects, parameter objects, variable objects, enumerations, and constants, etc., that is, the data dictionary is a collection of many data objects. The Simulink model does not need to be reloaded during operation, and data is automatically searched from the data dictionary. The data dictionary is traceable, it not only records data, but also records the modification behavior and version of the data. The technical solution of this application realizes the rapid creation of control variables and calibrated observation quantities for the integration of upper and lower layers of hydrogen-fired power control systems through computer programming means. Specifically:

[0052] This application first sorts out the data object types, names, etc. of the control variables and calibration observations involved in the hydrogen-fired power control system and stores them in a spreadsheet; using the control variable information in the spreadsheet as the basic data source, the control variable information in the spreadsheet is written into the data dictionary of the hydrogen-fired power control system through programming in a DataDictionary manner that satisfies the Simulink model.

[0053] See Figure 2 , is a flow chart of a method for creating a data dictionary provided in an embodiment of the present application. Figure 2 The method shown includes the following implementation steps:

[0054] S201. Obtain control variable information in a hydrogen fuel cell control system.

[0055] There are nearly 2,000 pieces of control variable information involved in the hydrogen-fired power control system of this application (specifically, the upper and lower integrated control variables in the system), which specifically include four categories: variable information (MTALAB Variable), parameter information (SimulinkParameter), two-dimensional lookup table information (Simulink LookupTable function) and signal line information (SimulinkSignal), etc.

[0056] In an optional embodiment, the present application may first obtain the initial variable information in the hydrogen-fired power control system, and then classify and sort the initial variable information to obtain the control variable information. The control variable information includes four types of information: variable information, parameter information, two-dimensional lookup table information and signal line information.

[0057] Among them, the variable information, the parameter information, the two-dimensional lookup table information and the signal line information are all customized settings of the hydrogen fuel cell control system. For example, the Simulink Parameter includes but is not limited to: Coolt_pStkInStartThreshold_C (stack cooling water pressure establishment threshold), Coolt_tStkOutStopThreshold_C (shutdown completion cooling water temperature threshold), FCState_stTestCtrl_C (state machine test control state), FCState_stTest_C (state machine test state), FC_iDeloadThreshold_C (load reduction completion current threshold setting) and FC_iIdleThreshold_C (idle state switching current threshold), etc. The Simulink Signal (signal line) includes but is not limited to: Coolt_tStkOutStopThreshold (cooling water temperature threshold for shutdown completion), Dsm_EepromInfoOld (EEPROM memory status check), FCState_st (fuel cell status), FCState_stRaw (fuel cell status raw value), FCState_stTest (fuel cell test status), FC_stDeloadOverFlg (unloading completion flag), FC_stIdleToRunFlg (running state switching flag), FC_stVlvStopFlg (valve closing flag), FC_tiIdle (idle operation timer), FC_tiIdleAlow (maximum idle time allowed), IdleState_In (entering idle state) and IdleState_Out (exiting idle state), etc.

[0058] It should be noted that the control variable information corresponding to each control variable includes one or more field information, for example, it may include but is not limited to any one or more combinations of the following field information: Order (serial number), Name (name), Status (status), Value (initial value), DataType (variable type), Dimensions (dimensions), Complexity (complex type), Min (minimum value), Max (maximum value), Unit (unit) and StorageClass (storage type), etc.

[0059] S202: Construct dictionary basic information for the control variable information to obtain corresponding dictionary basic information.

[0060] The present application can convert the sorted control variable information into the corresponding dictionary basic information in the form of a preset storage format, so as to serve as a data source for creating a data dictionary of a Simulink model of a hydrogen fuel cell control system.

[0061] The preset storage format is a system-defined format, such as an Excel spreadsheet, etc. Taking an Excel spreadsheet as an example, the present application can store the sorted control variable information in an Excel spreadsheet as a data source for creating a data dictionary.

[0062] It should be noted that this application constructs the control variable information sorted out by S201 into Excel dictionary basic information in a standard format. At the same time, it is very important to determine the specific value of each field information in the dictionary basic information. The accuracy of the variable definition directly affects the accuracy of the Simulink model of the hydrogen-fired power control system. In particular, the StorageClass (storage type) in the dictionary basic information determines the storage type of the control variable in the data dictionary. The variable storage types supported by the Simulink data dictionary include, but are not limited to, constants, calibrated observations, lookup two-dimensional lookup tables, and signal lines. For example, please refer to the following Table 1 which shows the dictionary basic information of a possible Excel spreadsheet.

[0063] Table 1

[0064]

[0065] S203: Create a corresponding data dictionary for the hydrogen-fired power control system according to the basic dictionary information using programming technology.

[0066] Please also see Figure 3 , is a flow chart of another method for creating a data dictionary provided in an embodiment of the present application. Figure 3 The data dictionary creation process is shown to include four parts: sorting out the upper and lower control variables of the hydrogen-fired power control system (S301), constructing the basic information of the control variable data dictionary (S302), programming techniques for implementing the control variable to data dictionary function (S303), and creating a reference to the data dictionary function function (S304). Among them, steps S301 and S302 can correspond to the relevant descriptions of the aforementioned steps S201 and S202, and will not be repeated here. Steps S303 and S304 can correspond to step S203, and their specific implementation is as follows:

[0067] First, this application can define a function that converts dictionary basic information into a data dictionary, such as defining a function importExcelToDD() that converts Excel dictionary basic information into a data dictionary. Among them, functionimportExcelToDD(workbookFile, dictionaryName); wherein workbookFile is the Excel dictionary basic information including control variable information; dictionaryName is the ssld file that converts Excel's control variable information into a Simulink data dictionary to store the converted data dictionary information. In addition, the two-dimensional lookup table in the workbook in which this application converts Excel's dictionary basic information into a data dictionary can be of any size. In the full-page browsing of the workbook, the Excel dictionary basic information is divided into breakpoints, tables (cells) and their name identifiers. Assuming that breakpoint 1 is in the first column and breakpoint 2 is in the first row, cells A2, B1 and B2 define the breakpoint name and table name, and the Excel dictionary basic information is to be stored in the design data (design data) part of the data dictionary. Entries can be created in the data dictionary to store the corresponding conversion breakpoints and conversion tables.

[0068] Next, create a data dictionary file myExcelToDD.sldd for storing the data dictionary, which can also be understood as creating a data dictionary to store information table data. Specifically, this application can first define a data dictionary object, such as myDictionaryObj, and create a data dictionary file name, such as myExcelToDD.sldd; further assign the created data dictionary file name to the defined data dictionary object, as shown in the following code:

[0069] myDictionaryObj=Simulink.data.dictionary.create('myExcelToDD.sldd')

[0070] Then, in the function that defines how to convert the basic information of the Excel dictionary into a data dictionary, specify the data dictionary file. The code is as follows:

[0071] importExcelToDD('controlvar.xlsx', 'myExcelToDD.sldd')

[0072] Furthermore, the application can call the function that converts the Excel dictionary basic information into a data dictionary to convert the dictionary basic information into a data dictionary. Specifically, when the application calls the function that converts the Excel dictionary basic information into a data dictionary, the variables workbookFile and dictionaryName are input, where:

[0073] workbookFile='controlvar.xlsx'

[0074] dictionaryName='myExcelToDD.sldd'

[0075] The code is as follows:

[0076] importExcelToDD('controlvar.xlsx', 'myExcelToDD.sldd')

[0077] Furthermore, this application can open the data dictionary in the model explorer. Specifically, this application opens the created data dictionary in the Simulink model explorer and checks the correctness of the data dictionary creation, such as whether the software cannot automatically open the data dictionary, or whether the information of each field of the control variable information is correct. If it is correct, continue to execute the subsequent process; otherwise, end the process. See Figure 4 Schematic diagram showing a possible data dictionary in the Simulink Model Explorer.

[0078] Furthermore, this application saves the function as a preset format file, for example, as a Matlab m file, importExcelToDD.m, etc. Specifically, this application converts the constructed dictionary basic information of the Excel control variable into a function of the data dictionary of the Simulink model and saves it as a Matlab m file named importExcelToDD.m.

[0079] Finally, the application can create a reference to the data dictionary function myExcelToDD.sldd. Specifically, the application can first create a data dictionary object, the code is as follows:

[0080] myDictionaryObj=Simulink.data.dictionary.create('myExcelToDD.sldd');

[0081] Then call the command to display the data dictionary object. The calling command code is as follows:

[0082] show(myDictionaryObj).

[0083] It should be noted that the programming languages that may be involved in this application include Excel and Matlab, but are not limited to them.

[0084] By implementing the present application, the present application obtains control variable information in a hydrogen-fired power control system, then constructs dictionary basic information for the control variable information to obtain corresponding dictionary basic information, and then uses programming technology to directly create a corresponding data dictionary for the hydrogen-fired power control system based on the dictionary basic information. Compared with manually creating a data dictionary, the present application can directly use programming technology to achieve fast and intelligent creation of a data dictionary for a hydrogen-fired power control system, thereby saving dictionary creation time, improving creation efficiency, and reducing error rate. At the same time, it also solves the technical problems of low efficiency and low accuracy in manually creating data dictionaries in the existing technology.
