Description of the drawings
[0061] The following further describes the present invention in detail with reference to the drawings and specific embodiments, and the above and / or other advantages of the present invention will become clearer.
[0062] Figure 1 is a schematic diagram of the system composition of the present invention.
[0063] Figure 2 is a schematic diagram of the general information encoding and decoding method. Specific embodiments
[0064] The present invention provides a general information encoding and decoding system and method based on a code table, which uses a code table-based method to uniformly encode and decode interactive information. The information sender integrally calls the encoding interface, and the information receiver integrally calls the decoding interface to achieve consistent encoding and decoding of the interactive information. This method is extensible for development languages and parameter types, avoiding potential code defects and repetitive code development and modification work during the joint debugging of large systems.
[0065] Technical solution: A general information encoding and decoding method based on a code table, including: an interactive information encoding and decoding interface module, an interactive information encoding module, an interactive information decoding module, and a set of interactive information category code tables, which include: an interactive information parameter code table, a development language parameter type code table, and an interactive information category code table, as Figure 1 shown:
[0066] Among them, the interactive information encoding module converts each parameter in the interactive information into a string in a specified format according to its type, including: digital parameter encoding, string parameter encoding, time parameter encoding, longitude and latitude parameter encoding, angle parameter encoding, and development language-specific type parameter encoding;
[0067] The interactive information decoding module is a process inverse to interactive information encoding. It reversely converts a string into the original corresponding type according to the parameter type, including: digital parameter decoding, string parameter decoding, time parameter decoding, longitude and latitude parameter decoding, angle parameter decoding, and decoding of parameter types specific to the development language.
[0068] In the code table,
[0069] The parameter type code table stores the parameter types used in the development language;
[0070] The interactive information category code table stores information such as the classification identifier, information classification, parameter type, parameter format, and length requirement of all interactive information. The interactive information encoding module converts each parameter in the interactive information into a string of a specified format according to its type; the interactive information decoding is the opposite of the interactive information encoding process, which reversely converts the string into the original corresponding type according to the parameter type.
[0071] For example, Figure 2 As shown, when performing information interaction, the information sender fills in the corresponding parameter types and interactive information attributes of the development language in the code table, calls the unified encoding interface, and the receiver calls the unified decoding interface. Both parties do not need to do additional development work on the interactive information parsing code. In the case of multiple interactive systems, variable interactive interfaces, and a large variety of information types, it can effectively avoid code defects and a large amount of code modification and rework.
[0072] The principle of the present invention is: The general information encoding and decoding method defines the encoding and decoding methods for all types of information. When sending and receiving information, the encoding and decoding methods perform encoding and decoding on the interactive information formats and contents pre-stored in the code table, realizing the reuse of the interactive information encoding and decoding functions.
[0073] Embodiment:
[0074] 1. Design of the parameter type code table for the development language
[0075] The parameter types used in the development language are formed into a parameter type code table TY_S_ParameterType for the development language, as shown in Table 1.
[0076] Table 1 Data element table of the parameter type code table TY_S_ParameterType for the development language
[0077]
[0078] As shown in Table 2, it is a code table of common parameter types for the QT language. This code table can be supplemented according to actual needs or common parameter types; the parameter type code tables defined for other development languages such as C++, JAVA, and Python are similar.
[0079] Table 2 QT language parameter type code table
[0080]
[0081]
[0082] 2. Design of interactive information category code table and interactive information parameter code table
[0083] All possible interactive information categories in the system and the specific format of each information are saved in the interactive information category code table and the interactive information parameter code table, which are table TY_S_MutualInformation and table TY_S_MutualInformationParameter, as shown in Table 3 and Table 4. Among them, table TY_S_MutualInformation stores all interactive information categories, and uniquely identifies information through information code identification; table TY_S_MutualInformationParameter stores specific parameter information of each category information, including the order of each parameter, parameter type, parameter format or length requirements, etc., and associates the main table TY_S_MutualInformation through the "interactive information category" foreign key.
[0084] The two data fields, information major category and information minor category, can be used to classify information according to application settings. For example, the major category of information of a type is control instruction information, and the minor category is simulation speed setting. By broadcasting this information to the entire system, the simulation speed of the entire system can be uniformly adjusted.

[0086]
[0087] Table 4 Data element table of mutual information parameter code table TY_S_MutualInformationParameter

[0089] For example, the interactive information with information category ID 030501 has the following format and content.

[0091]
[0092] The data row record of the mutual information with information category ID 030501 in table TY_S_MutualInformation is as follows:
[0093] Table 6 shows the data element table of sample interaction information in the table TY_S_MutualInformation
[0094] Code identifier Code description Major information category Minor information category Remarks 030501 13 03 05
[0095] The record of the interaction information with the information classification ID of 030501 in the table TY_S_MutualInformationParameter is as follows:
[0096] Table 7 shows the data element table of sample interaction information in the table TY_S_MutualInformationParameter
[0097]
[0098]
[0099] 3. Interaction Information Encoding
[0100] The interaction information encoding is to convert each parameter in the interaction information into a string in a specified format according to its type, mainly including six types of conversions: digital parameters, string parameters, time parameters, longitude and latitude parameters, angle parameters, and development language-specific type parameters, etc.
[0101] 1) Digital parameter encoding: For integers, directly convert to a string; for decimals, according to the data precision requirements, retain the specified number of decimal places after the decimal point and convert to a string;
[0102] 2) String parameter encoding: Directly convert to a string;
[0103] 3) Time parameter encoding: Convert to a string according to the specified format data display requirements;
[0104] 4) Longitude and latitude parameter encoding: Convert to a string according to the specified longitude and latitude format data display requirements, and retain the specified precision data for seconds;
[0105] 5) Angle parameter encoding: Convert to a string according to the specified format angle data display requirements, and retain the specified precision data for seconds;
[0106] 6) Development language-specific type parameter encoding: Customize the development according to the development language. For example, for QPoint in QT, convert the corresponding x coordinate and y coordinate to strings and then connect them with ",", forming "x, y"; for the QStringList type in the example, splice each string with "&&" to form a long string.
[0107] 4. Interaction Information Decoding
[0108] Interactive information decoding is a process inverse to interactive information encoding, which reversely converts a string into the original corresponding type according to the parameter type.
[0109] 5. Interactive Information Encoding and Decoding Interface
[0110] Taking the QT development language as an example, the interactive information encoding and decoding interface is described below.
[0111] 1) Basic Structure of Interactive Information MsgStruct_General
[0112] Provide the basic structure of interactive information MsgStruct_General.
[0113] struct MsgStruct_General
[0114] {
[0115] int nParaCount;
[0116] }
[0117] The member variable nParaCount represents the number of parameters included in the message;
[0118] All other information structures that need to interact are derived from the basic structure MsgStruct_General, and member variables are defined in sequence according to the parameter order. For example, define a structure for adjusting the simulation speed
[0119] struct MsgStruct_SetSimRate:MsgStruct_General
[0120] {
[0121] int nRate;
[0122] }
[0123] nRate represents the simulation speed that needs to be adjusted.
[0124] 2) Interactive Information Encoding Interface
[0125] (1) Interface Definition
[0126] bool MessageEncoding(QString strMsgTypeClass,QStringstrMsgTypeSection,MsgStruct_XX&structXX,QString&strMessage);
[0127] (2) Parameter Explanation
[0128] Input:
[0129] strMsgTypeClass represents the major category of information;
[0130] strMsgTypeSection represents the minor category of information;
[0131] structXX represents the information structure parameter to be encoded, and its structure is derived from MsgStruct_General;
[0132] strMessage represents the long string after encoding conversion.
[0133] Output:
[0134] Indicates the encoding result, true indicates success, and false indicates failure.
[0135] (3) Function process
[0136] According to the major category and minor category of information, for each actual value of each parameter in structXX in sequence according to the parameter order, call the corresponding interactive information encoding and conversion module according to the type, and convert it into a string with a specified length. If the numeric type is inconsistent with the "parameter type" in the interactive information generation parameter code table (TY_S_MutualInformationParameter) or the value does not meet the "format or length requirements", the function ends, gives a failure prompt, and returns false; connect the converted strings together pairwise with "@@!!&&" (used for splitting strings, can be adjusted as needed), finally form a long string, assign the final value to strMessage, and return true.
[0137] strMessage is the final encoding result; then call the transmission function to send out strMessage.
[0138] 3) Interactive information decoding interface
[0139] (1) Interface definition
[0140] bool MessageDecoding(QString strMsgTypeClass,QStringstrMsgTypeSection,MsgStruct_XX&structXX,QString&strMessage);
[0141] (2) Parameter description
[0142] Input:
[0143] strMsgTypeClass represents the major category of information;
[0144] strMsgTypeSection represents the minor category of information;
[0145] structXX represents the information structure parameters to be decoded, and its structure is derived from MsgStruct_General;
[0146] strMessage represents the decoded long string.
[0147] Output:
[0148] Represents the encoding result, true means success, and false means failure.
[0149] (3) Function process
[0150] Extract the strings separated by "@@!!&&" in strMessage, and then according to the major category and minor category of information, in the order of parameters, call the corresponding interactive information decoding and conversion module for the strings according to the type to convert them into specified format parameter values. If the conversion fails, the function ends, gives a failure prompt, and returns false; assign the converted parameter values to the corresponding parameters in structXX and return true.
[0151] structXX is the final decoding result.
