Abstract
Description
Technical Field
[0001] This application relates to the field of communication protocol technology, specifically to a method, apparatus, device, and medium for detecting and correcting message data formats. Background Technology
[0002] The Unified Diagnostic Services (UDS) protocol is a standardized diagnostic communication protocol widely used in automotive electronic systems. Developed based on the ISO 14229 standard, it is primarily used for fault diagnosis, data reading and writing, software programming, and system maintenance of Electronic Control Units (ECUs). CAN bus communication is widely used in automotive electronic systems; therefore, UDS protocol commands are typically sent via the CAN bus, and their format must adhere to the CAN protocol. The Data Field in the CAN protocol message format stores the transmitted data and can hold 64 bytes, or 16 hexadecimal bits. During development and testing, engineers often need to manually input hexadecimal data to simulate CAN messages.
[0003] However, the following problems exist when entering message data in traditional text input boxes: 1. The number of spaces cannot be limited, resulting in a large number of spaces and thus causing the entered message data to be non-standard in format, such as... Figure 1 As shown; 2. It requires manually adding a space separator to separate each byte (two hexadecimal numbers), which is tedious and error-prone. Figure 2 As shown; 3. Modifying already entered characters may result in a set of data containing three characters, causing an error during transmission, such as... Figure 3 As shown.
[0004] Therefore, how to automatically detect and correct the input message data is a technical problem that urgently needs to be solved. Summary of the Invention
[0005] This application provides a method, apparatus, device, and computer-readable storage medium for detecting and correcting message data format, which can solve the technical problem in the prior art that errors in sending message data due to non-standard format will occur when entering message data in a text box.

If so, then add a 0 before the previous bit of the new input byte.
[0009] In one implementation, based on the position and type of the new input byte in the input line, and the type of the already input bytes, a backspace operation, a zero-padding operation, and a space-padding operation are performed in the input line, including: When the position of the new input byte in the input line is greater than 2, and the new input byte is a character, if the first two digits of the new input byte are both characters, then a space is automatically added before the new input byte.
[0010] In one implementation, based on the position and type of the new input byte in the input line, and the type of the already input bytes, a backspace operation, a zero-padding operation, and a space-padding operation are performed in the input line, including: When the position of the new input byte in the input line is greater than 2 positions and the new input byte is a space, if the preceding position of the new input byte is a space, then a backspace operation is performed; If the first character of the new input byte is a character and the first two characters of the new input byte are spaces, then 0 is added before the first character of the new input byte.
[0011] In one implementation, after detecting a new input byte in the input line, the method further includes: Determine the cursor position in the input line; If the cursor is in the middle of the entered bytes, an input error message is displayed, and all entered bytes after the cursor are deleted.
[0012] In one implementation, when a new input byte is detected in the input line, determining the position and type of the new input byte in the input line, as well as the type of the bytes already input in the input line, further includes: When a new input byte is detected in the input line, it is determined whether the new input byte is either a character or a space that conforms to a preset format; If so, determine the position and type of the new input byte in the input line, as well as the type of the bytes already input in the input line; Otherwise, display a message indicating an error in the new input byte and delete the new input byte.

Detailed Implementation
[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0020] In a first aspect, embodiments of this application provide a method for detecting and correcting message data formats.
[0021] In one embodiment, reference is made to Figure 4 , Figure 4 This is a flowchart illustrating the first embodiment of the method for detecting and correcting the message data format of this application. Figure 4 As shown, the methods for detecting and correcting message data formats include: Step S101: When a new input byte is detected in the input line, determine the position and type of the new input byte in the input line, as well as the type of the bytes already input in the input line.
[0022] As a preferred implementation, after detecting a new input byte in the input line, the method further includes: determining the position of the cursor in the input line; if the cursor is in the middle of the already input bytes, displaying an input error message and deleting all already input bytes after the cursor.
[0023] It's worth noting that after detecting a new input byte in the input line, if the cursor is determined to be in the middle of the already entered byte sequence rather than at the end, it's determined that the user is in data modification mode. In this mode, direct modification of existing content may disrupt the established format, leading to inconsistencies in data format before and after the cursor position, and consequently causing message assembly errors. To fundamentally avoid such risks, such as... Figure 5 As shown, this embodiment will automatically display input error messages and clear all entered bytes after the cursor position, retaining only the valid content before the cursor. This mechanism ensures that any editing operation restarts from a standardized and consistent breakpoint, thereby forcibly maintaining the correctness and integrity of the entire data segment's format and effectively preventing global errors introduced by local modifications. For example, it effectively avoids situations where three characters are linked together due to modifications to already written characters.
[0024] In one embodiment, when a new input byte is detected in the input line, determining the length and type of the bytes already input in the input line further includes: when the new input byte is detected in the input line, determining whether the new input byte is either a character or a space that conforms to a preset format; if so, determining the position and type of the new input byte in the input line, as well as the type of the bytes already input in the input line; otherwise, displaying a prompt message indicating that the new input byte has an error, and deleting the new input byte.
[0025] It is worth noting that, such as Figure 6As shown, in this embodiment, characters conforming to the preset format can be hexadecimal numbers. This embodiment, through a pre-filtering mechanism, can fundamentally eliminate the input of any illegal characters, effectively avoiding the problem of interference with subsequent formatting logic or even communication protocol failure due to basic input errors, thereby ensuring the standardization and legality of the final message data from the source.
[0026] Step S102: Based on the length and type of the input bytes, perform backspace, zero-padding, and space-padding operations in the input line.
[0027] In one embodiment, when the new input byte is at the beginning of the input line, it is determined whether the new input byte is a space; if it is a space, a backspace operation is performed on the input line.
[0028] It is worth noting that message data must begin with a number, not a separator (space). A leading space has no data meaning and violates the basic formatting principle of "data first, separator last." This application uses a backspace when a space is entered at the beginning, eliminating illegal formats that start with a space and laying a correct foundation for the standardized input of subsequent data.
[0029] In one embodiment, when the new input byte is in the second position of the input line, it is determined whether the previous position of the new input byte is a character and whether the new input byte is a space; if so, 0 is added before the previous position of the new input byte.
[0030] It is worth noting that if the first character of the new input byte is a character and the new input byte is a space, it means that the user has only entered one character and then ended the input. This does not conform to the protocol specification of two bytes. At this time, the system automatically fills in 0s, instantly converting the incomplete input into a complete two-byte that conforms to the protocol specification. This eliminates the common formatting error of "missing digits" from the source, thereby avoiding tedious manual modification.
[0031] In one embodiment, when the position of the new input byte in the input line is greater than 2 positions, it is first determined whether the new input byte is a character or a space.
[0032] When the position of the new input byte in the input line is greater than 2, and the new input byte is a character, if the first two digits of the new input byte are both characters, then a space is automatically added before the new input byte.
[0033] As an example, if the first two digits of the new input byte are both characters "03", and the new input byte is the character "2", then it constitutes "032" which does not conform to the message data specification. This embodiment automatically adds a space before the new input byte to make the input conform to the specification as "03 2".
[0034] This embodiment identifies the complete byte pair "03" formed by continuous user input and automatically inserts a space after the user inputs the next character "2". This ensures that the message data is always presented in the standard format of "two digits + space", fundamentally preventing the problem of byte concatenation (three or more consecutive characters) caused by continuous input, and guaranteeing the standardization and readability of the data.
[0035] When the position of the new input byte in the input line is greater than 2 positions and the new input byte is a space, if the preceding position of the new input byte is a space, a backspace operation is performed to avoid consecutive spaces and ensure the standardization of the message data.
[0036] When the position of the new input byte in the input line is greater than 2, and the new input byte is a space, if the first character of the new input byte is a character, and the first two characters of the new input byte are spaces, then 0 is added before the first character of the new input byte.
[0037] As an example, taking the already entered message data as "10 33 5", if the user enters a space as the new input byte, intending to end the current byte, the user only enters one character "5" and ends the input, which is not a two-byte format that conforms to the protocol specification. At this time, the system automatically fills in 0, forming "10 33 05", and instantly converts the incomplete input into a complete two-byte format that conforms to the protocol specification, thereby eliminating the "missing byte" format error and avoiding tedious manual modification.
[0038] In a specific embodiment, such as Figure 7 As shown, the methods for detecting and correcting message data formats include: Step S201: Begin.
[0039] Step S202: A new input byte exists.
[0040] Step S203: Determine if the cursor is in the middle of the entered byte; if yes, proceed to step S204; if no, proceed to step S205.
[0041] Step S204: Display the input error message and delete all entered bytes after the cursor, then return to step S201.
[0042] Step S205: Determine whether the new input byte is a hexadecimal character or a space; if not, proceed to step S206; if yes, proceed to step S207.
[0043] Step S206: Display a message indicating an error in the new input byte, delete the new input byte, and return to step S201.
[0044] Step S207: Determine whether the new input byte is at the beginning of the input line; if yes, proceed to step S208; if no, proceed to step S2010.
[0045] Step S208: Determine if the new input byte is a space; if yes, proceed to step S209; if no, return to step S201.
[0046] Step S209: Perform a backspace operation in the input line and return to step S201.
[0047] Step S2010: Determine whether the new input byte is in the second position of the input line; if yes, proceed to step S2011; if no, proceed to step S2013.
[0048] Step S2011: Determine whether the preceding character of the new input byte is a character and whether the new input byte is a space; if yes, proceed to step S2012; if no (both are characters), return to step S201.
[0049] Step S2012: Add 0 before the first element of the new input byte, and shift the original content to the right.
[0050] Step S2013: Determine whether the new input byte is a character or a space; if it is a character, proceed to step S2014; if it is a space, proceed to step S2016.
[0051] Step S2014: Determine whether the first two digits of the new input byte are both characters; if yes, proceed to step S2015; otherwise, return to step S201.
[0052] Step S2015: Automatically add spaces before the newly input bytes, then return to step S201.
[0053] Step S2016: Determine if the first character of the new input byte is a space; if yes, proceed to step S2017; otherwise, proceed to step S2018.
[0054] Step S2017: Perform a backspace operation and return to step S201.
[0055] Step S2018: Is the first character of the new input byte a character, and are the first two characters of the new input byte a space? If yes, proceed to step S2019; otherwise, proceed to step S201. Step S2019: Add 0 to the beginning of the new input byte, then return to step S201.
[0056] The message data format detection and correction method provided in this application's embodiments accurately determines the specific position of a new input byte in the data stream, its own attributes (hexadecimal number or space), and the combination state of preceding characters (such as whether the first two digits constitute a complete byte). It automatically triggers precise correction mechanisms such as backspace deletion, intelligent zero padding for incomplete bytes, and automatic space padding for byte separators. This method can complete accurate formatting without the user's awareness, completely solving the unavoidable formatting anomalies such as extra spaces, missing digits, and misalignments in manual input mode. This not only ensures that the final generated message data fully complies with the strict specifications of communication protocols such as the CAN bus, eliminating communication failures caused by format errors at the source, but also significantly improves work efficiency and data reliability in diagnostic, testing, and development processes in fields such as automotive electronics, achieving a unified improvement in accuracy, efficiency, and ease of use.
