[0002] In the modern automobile production process, the PDI inspection before the vehicle leaves the factory is an important process, which is mainly used to detect whether the various functions of the vehicle are normal and record relevant information to ensure that the quality of the vehicles delivered to customers meets the standards. Traditional PDI inspection information flow management usually relies on manual records or partial automation tools, which has certain limitations in practical applications.

[0003] At present, many production lines have introduced the automatic nameplate printing function, which is used to generate nameplates in real time after the vehicle completes the PDI inspection to indicate the vehicle's inspection results and related information. However, since the management of the PDI inspection information flow is easily affected by network delays, system asynchrony and other issues during transmission and processing, it often causes nameplate printing information errors or delays. For example, when the vehicle information has not been fully synchronized to the printing system, erroneous information may be printed, or manual intervention may be required to correct the printing results, reducing production efficiency and increasing the risk of errors. In addition, since most existing nameplate printing systems lack the ability to monitor the PDI inspection information flow in real time, when information flow delays or data transmission errors occur, it is difficult for the system to detect and handle them in a timely manner, thereby affecting the accuracy of nameplate printing and the overall efficiency of the production line. This lack of efficient information synchronization and real-time monitoring capabilities has become an important issue that restricts the reliability and automation level of the nameplate printing system.

[0016] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, the present invention provides a technical solution: a method for automatic nameplate printing without PDI based on computer algorithm, the method comprising: S1, collect and transmit PDI inspection information to the central processing system in real time based on the vehicle identification number; S2. The central processing system parses and verifies the integrity and consistency of the received PDI inspection information, including calculating the relative growth rate of information parsing and verification during the verification process. The specific formula is: r = ΔN / (N × Δt); Where r represents the relative growth rate of information parsing and verification, ΔN represents the number of fields parsed and verified, N represents the total number of fields in the information flow, and Δt represents the time taken; S3. Update the vehicle status based on the verification result and synchronize it to the nameplate printing terminal, including modeling the status update process and calculating the status update rate. The specific formula is: P = A / t; Where P represents the state update rate, A represents the total amount of vehicle states that need to be updated, and t represents time; When synchronizing the vehicle status to the nameplate printing terminal, the synchronization progress is recorded in real time and the synchronization status is monitored for abnormalities. After the synchronization is completed, it is confirmed that all vehicle statuses are successfully updated to ensure that the printing terminal receives the correct information; S4. Generate and execute a nameplate printing instruction according to the synchronized vehicle status.

[0019] This method collects and transmits PDI inspection information to the central processing system in real time through the vehicle identification number, so that the inspection data can be updated and processed in real time. In the central processing system, information parsing and verification evaluates the processing efficiency by calculating the formula r=ΔN / (N×Δt), thereby optimizing the real-time and accuracy of the parsing and verification process. Based on the verified data, the system further uses the formula P=A / t to model and optimize the rate of the vehicle status update process to ensure the update efficiency. In the process of synchronizing the vehicle status to the nameplate printing terminal, the system can record the synchronization progress in real time, and ensure the reliability and integrity of the synchronization process through the abnormal monitoring mechanism. Finally, accurate printing instructions are generated according to the synchronized status data, thereby completing the automated nameplate printing task. Compared with traditional methods, this method achieves high efficiency and reliability through full-process automation based on computer algorithms. The introduction of the information parsing and verification formula r=ΔN / (N×Δt) optimizes the real-time and accuracy of data verification and significantly improves the parsing efficiency. The modeling of the status update rate formula P=A / t enhances the efficiency and accuracy of data synchronization, and at the same time ensures the reliability and error-freeness of the synchronization process through real-time progress recording and abnormal monitoring. The entire process, from data collection to the execution of printing instructions, achieves efficient operation without human intervention, significantly improves production efficiency and reduces the risk of errors, demonstrating strong practical value and technical advantages.

[0020] S1 includes modeling the strength of the vehicle identification number and PDI inspection information collection signal, measuring the distance between the collection device and the central processing system, and calculating the signal strength. The specific formula is: L = B / d 2 ; Where L represents the signal strength, B represents the power of the acquisition device, and d represents the distance between the acquisition device and the central processing system.

[0021] In this implementation, by modeling the collected signal strength, the signal transmission quality of the vehicle identification number and PDI inspection information can be quantified. The signal strength model is based on the formula L = B / d 2 It is represented by: the signal strength L is the power B and the square of the distance d from the acquisition device to the central processing system 2The inverse relationship between the signal strength and the power of the acquisition device is obtained by measuring the actual distance d between the acquisition device and the central processing system, and combining it with the power B of the acquisition device to calculate the signal strength L to ensure the reliability and stability of signal acquisition and transmission. This modeling process optimizes the layout of the acquisition equipment and reduces the risk of signal transmission delay or data loss. By modeling the acquisition signal strength, this method significantly improves the accuracy and stability in signal acquisition and transmission. Real-time signal strength monitoring makes the layout of the acquisition equipment more scientific, reduces the risk of interference and data loss, and ensures the integrity of the PDI inspection information. The signal strength model is applicable to a variety of scenarios, enhances the deployment flexibility of the system, and provides reliable data support for subsequent vehicle status updates and nameplate printing, which comprehensively improves the efficiency and reliability of the system.

[0022] S4 includes modeling the synchronized vehicle status fields, calculating the comprehensive frequency of all fields, and generating the final printing instruction template. The specific formula is: ; Where, f represents the printing frequency of the comprehensive generation, n represents the number of vehicle status fields after synchronization, i represents the number of fields, and f represents the number of fields. i Indicates the frequency value of each vehicle status field; Send the printing instructions to the printing terminal to ensure that the printing task is completed in the correct order of the vehicle status fields. After printing is completed, record the printing log and feedback the status to the central processing system to ensure the closed-loop execution of the entire process.

[0023] In this embodiment, the calculation of the printing frequency and the generation of the instruction template are realized by modeling and analyzing the synchronized vehicle status field. The comprehensive printing frequency is calculated by the formula The calculation shows the average frequency of all vehicle status fields. The generated printing instruction template is supported by the frequency model to ensure that the instructions are carried out in the correct order of the fields. After printing is completed, the printing status is synchronized to the central processing system through the log recording and feedback mechanism to achieve data closed-loop management and ensure the integrity of the task and the efficiency of the process. This implementation method significantly improves the efficiency and accuracy of the printing task through the optimization of printing frequency modeling and instruction template generation. The calculation of printing frequency ensures the coordination of synchronization fields and avoids field loss or order errors. Recording the printing log and feeding back the status to the central processing system forms a closed-loop management process, which further improves the reliability of task execution and data tracking capabilities. In addition, this method enhances the controllability of printing tasks and the overall performance of the system.

[0024] The status update data synchronized to the nameplate printing terminal in S3 includes the unique identification information of the vehicle, the inspection project results and the timestamp information. In this embodiment, when the vehicle status update data is synchronized to the nameplate printing terminal, it includes the unique identification information, the inspection project results and the timestamp information of the vehicle. The unique identification information is used to accurately mark the vehicle to ensure that the status data of each vehicle is not confused; the inspection project results record the detailed results of the PDI inspection and provide a basis for the printed content; the timestamp information ensures the real-time nature and data tracking capability of the synchronization process. Through these data, the printing terminal can accurately receive complete and reliable status update information, thereby providing support for subsequent printing tasks. The synchronization data design of this embodiment is comprehensive and accurate, including unique identification information, inspection project results and timestamp information, which significantly improves the reliability and accuracy of data synchronization. The unique identification information ensures the accurate positioning of the vehicle status and avoids data confusion; the inspection project results ensure that the content printed on the nameplate is accurate; the timestamp information enhances the traceability of the synchronization process, which facilitates the system to troubleshoot and optimize the process. This data design not only improves the efficiency of the entire process, but also provides guarantees for data integrity and accuracy.

[0025] S4 also includes grouping the generated nameplate printing instructions according to the number and content of the vehicle status fields. In this embodiment, the generated nameplate printing instructions are grouped according to the number and content of the vehicle status fields to optimize the execution efficiency of the printing task. Specifically, when parsing the vehicle status field, the system classifies the printing instructions according to the number of fields, and groups the instructions with similar number of fields or the same field content. Each group of printing tasks can be arranged in order according to priority or field characteristics, thereby optimizing the printing process and avoiding waste of equipment resources. At the same time, grouping processing facilitates task allocation and execution monitoring, further improving the accuracy and efficiency of printing. By grouping the printing instructions, this embodiment achieves higher flexibility and efficiency in the organization and execution of printing tasks. The grouping mechanism significantly reduces the conflict and resource waste of printing tasks, especially in the multi-task parallel scenario, and improves the utilization rate of printing equipment. Grouping by field content and quantity makes the instruction processing more standardized, ensures the accuracy of the printing content, and facilitates the system to monitor and dynamically adjust the tasks in real time. This optimized design enhances the reliability and adaptability of the system and meets the efficient printing requirements in complex production environments.

[0026] In S4, a barcode or a two-dimensional code is added to the nameplate. In this embodiment, when the nameplate printing instruction is generated, the system generates a unique barcode or a two-dimensional code for each vehicle by parsing and encoding the vehicle status data. The barcode or the two-dimensional code contains the unique identification information of the vehicle, the PDI inspection result, the production batch and other necessary information. This information is embedded in the barcode or the two-dimensional code by encoding and attached to the printed nameplate. The generation and printing of the barcode or the two-dimensional code can realize rapid data identification and tracing, and provide convenience for subsequent logistics management, quality tracking and maintenance support. The design of the additional barcode or the two-dimensional code significantly enhances the functionality of the nameplate, so that the relevant information of the vehicle can be quickly obtained through the scanning device. Compared with the traditional nameplate, this method improves the efficiency of information reading and reduces the error rate of manual input. In addition, the information contained in the barcode and the two-dimensional code is rich and compact, which supports the system to carry out accurate data tracing and management, and adapts to the needs of efficient management in a modern production environment. This additional design also facilitates the subsequent full-process monitoring and traceability, and comprehensively improves the intelligent level of production, logistics and after-sales service.

[0027] The barcode or QR code described in S4 includes summary information of the vehicle status field for subsequent verification and tracing. In this embodiment, the summary information of the vehicle status field is embedded in the barcode or QR code, which is generated by a specific hash algorithm or data compression technology to ensure that the key status data of the vehicle is concise and completely encoded. The summary information usually includes the vehicle identification number, the inspection item results, the timestamp and other key fields for rapid identification and verification of the vehicle's status data. The generated barcode or QR code can be decoded by a scanning device to provide fast and reliable data support in the subsequent logistics, production verification and quality tracing process. This mechanism effectively reduces the redundancy of information transmission and improves the efficiency and accuracy of data tracing. By including the summary information of the vehicle status field in the barcode or QR code, this embodiment further enhances the practicality and efficiency of the data. The embedding of the summary information enables the barcode or QR code to be used not only to uniquely identify the vehicle, but also as a direct entry for status data verification and tracing, simplifying the subsequent verification process. Compared with the traditional nameplate design, the introduction of summary information greatly reduces the verification time, improves the operational efficiency of production, logistics and maintenance links, and reduces the overhead of data storage and transmission through compression and encoding. This design also improves the data consistency and traceability accuracy of the system, and is particularly suitable for production and supply chain management scenarios that require rapid response.

[0028] The status update data synchronized to the nameplate printing terminal in S3 also includes the production batch information of the vehicle. In this embodiment, when the vehicle status update data is synchronized to the nameplate printing terminal, in addition to the unique identification information of the vehicle, the inspection item results and the timestamp information, the production batch information of the vehicle is also added. The production batch information is used to identify the manufacturing batch of the vehicle, and can associate the vehicle with its corresponding production link. After this information is synchronized to the printing terminal through the system, it provides additional data support for subsequent production management, quality control and traceability analysis. By adding production batch information during the status update process, the system can more comprehensively reflect the production and testing process of the vehicle and improve the integrity and practicality of the data. Adding production batch information significantly enhances the comprehensiveness of data synchronization, so that the status data of the vehicle contains more dimensional information, which provides strong support for subsequent production management and quality control. The synchronization of production batch information facilitates the rapid positioning of related vehicles when quality problems or supply chain anomalies occur, and improves the responsiveness and traceability efficiency of the system. At the same time, this information can generate more accurate nameplate content for the printing terminal to meet the management needs of different production scenarios, thereby further optimizing the collaborative ability of production and supply chain.

[0029] The final printing instruction template generated in S4 also includes an additional information field of the vehicle. In this embodiment, in order to improve the flexibility and information integrity of the printing instruction template, the additional information field of the vehicle is added when the final printing instruction template is generated. These additional information fields may include the color, configuration parameters, manufacturing date, warranty information, etc. of the vehicle, and are defined and expanded according to actual needs. In the process of generating the printing instruction template, the system integrates these additional fields with the core status field and transmits them to the printing terminal through the instruction template, so that the printed nameplate can contain richer vehicle information. This design ensures the comprehensiveness of the printed content and provides a more sufficient data basis for subsequent quality traceability, customer service and maintenance support. By adding additional information fields for the vehicle, the functionality and applicability of the printing instruction template are significantly enhanced. The introduction of additional fields not only expands the scope of information covered by the nameplate, but also meets more diverse production and management needs. The rich printing content improves the traceability of vehicle information, provides more basis for after-sales service and customer management, and provides flexibility for specific market or customer customization needs in the nameplate design. In addition, this method can also support the refined operation of production and management links and improve the efficiency and reliability of the overall system.

[0030] The frequency value f of each vehicle status field in S4 i The calculation formula is: i =w i ×u i ; Among them, f iRepresents the frequency value of each vehicle status field, w i Indicates the weight of the field, u i Indicates the priority of the field, and i indicates the number of the field.

[0031] In this embodiment, the frequency value f of the vehicle status field i By formula f i =w i ×u i Calculate the weight of the field w i Used to reflect the importance of the field in the printing instruction, the priority of the field i It indicates the execution order or urgency of the field in the current task. By comprehensively considering the field weight and priority, the frequency value f is calculated. i It is possible to quantify the relative importance of each field in the instruction generation. This formula ensures that when generating the printing instruction template, different fields are sorted or grouped according to their frequency values ​​to meet the accuracy and timeliness requirements of the printing task. This implementation significantly improves the scientificity and flexibility of printing instruction generation by introducing a comprehensive calculation of field weights and priorities. Field frequency value f i The dynamic calculation enables the system to flexibly adjust the importance and processing order of fields according to actual needs, thereby optimizing the execution efficiency of printing tasks. This method also enhances the system's adaptability to complex task scenarios, such as resolving multi-field priority conflicts or dynamically adjusting task weights. In addition, this design provides data support for the refined management of the printing process, further improving production efficiency and the reliability of data management.
