Description

Technical Field

[0001] The present invention relates to the technical fields of industrial automation and information processing, and particularly relates to a method for automatically printing a nameplate without vehicle allocation passing through PDI based on computer algorithms. Background Art

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

[0003] Currently, many production lines have introduced the function of automatically printing nameplates, which is used to generate nameplates in real time after the vehicle completes the PDI inspection to indicate the inspection results and relevant information of the vehicle. However, due to the management of the PDI inspection information flow being easily affected by problems such as network latency and system asynchronization during transmission and processing, it often leads to incorrect or delayed nameplate printing information. For example, when vehicle information has not been fully synchronized to the printing system, incorrect information may be printed, or manual intervention is required to correct the printing result, 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 latency or data transmission errors occur, it is difficult for the system to detect and process them in a timely manner, thus 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 problem restricting the improvement of the reliability and automation level of the nameplate printing system.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figure 1 shown, the present invention provides a technical solution: a computer algorithm-based PDI automatic nameplate printing method without vehicle allocation, the method comprising:

[0032] S1. Collect and transmit PDI inspection information to the central processing system in real time based on the vehicle identification number;

[0033] S2. The central processing system analyzes and verifies the integrity and consistency of the received PDI inspection information, including calculating the relative growth rate of information analysis and verification during the verification process, and the specific formula is: r = ΔN / (N × Δt);

[0034] Among them, r represents the relative growth rate of information parsing and verification, ΔN represents the number of fields for which parsing and verification are completed, N represents the total number of fields in the information stream, and Δt represents the time taken;

[0035] 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;

[0036] Among them, P represents the status update rate, A represents the total amount of vehicle status to be updated, and t represents the time;

[0037] When synchronizing the vehicle status to the nameplate printing terminal, record the synchronization progress in real time and monitor whether the synchronization status is abnormal. After synchronization is completed, confirm that all vehicle statuses have been successfully updated to ensure that the printing terminal receives the correct information;

[0038] S4. Generate and execute the nameplate printing instruction according to the synchronized vehicle status.

[0039] This method collects and transmits PDI inspection information to the central processing system in real time through the vehicle identification number, enabling the inspection data to be updated and processed immediately. In the central processing system, information parsing and verification evaluate the processing efficiency through the calculation formula r = ΔN / (N × Δt), thereby optimizing the real-time performance and accuracy of the parsing and verification process. Based on the verified data, the system further models and optimizes the vehicle status update process using the formula P = A / t to ensure the update efficiency. During 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 an anomaly monitoring mechanism. Finally, accurate printing instructions are generated based on the synchronized status data, thus 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 performance and accuracy of data verification, significantly improving 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, through real-time progress recording and anomaly monitoring, ensures the reliability and error-free nature of the synchronization process. The entire process from data collection to the execution of printing instructions realizes efficient operation without manual intervention, significantly improving production efficiency and reducing the risk of errors, demonstrating strong practical value and technical advantages.

[0040] S1 includes modeling the signal strength of the vehicle identification number and the 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 ;

[0041] Among them, 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.

[0042] In this embodiment, by modeling the acquired signal strength, the signal transmission quality of the vehicle identification number and PDI inspection information can be quantified. The signal strength model is represented by the formula L = B / d 2 which means that the signal strength L is the inverse proportional relationship between the power B and the square of the distance d from the acquisition device to the central processing system 2 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, the signal strength L is calculated to ensure the reliability and stability of signal acquisition and transmission. This modeling process optimizes the layout position of the acquisition device and reduces the risk of signal transmission delay or data loss. By modeling the acquired 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 device more scientific, reduces interference and data loss risks, and ensures the integrity of PDI inspection information. The signal strength model is applicable to various scenarios, enhances the deployment flexibility of the system, and provides reliable data support for subsequent vehicle status updates and nameplate printing, comprehensively improving the efficiency and reliability of the system.

[0043] S4 includes modeling the synchronized vehicle status fields, calculating the comprehensive frequency of all fields, and generating the final print instruction template. The specific formula is: ;

[0044] where f represents the comprehensively generated print frequency, n represents the number of synchronized vehicle status fields, i represents the field number, and f i represents the frequency value of each vehicle status field;

[0045] Send the print instruction to the printing terminal to ensure that the printing task is completed in the correct order of the vehicle status fields. After printing, record the printing log and feedback the status to the central processing system to ensure that the entire process is executed in a closed loop.

[0046] In this embodiment, by modeling and analyzing the synchronized vehicle status fields, the calculation of the print frequency and the generation of the instruction template are realized. The comprehensive print frequency is calculated by the formula Calculation is performed to reflect the average frequency of all vehicle status fields. The generated printing instruction template is supported by a frequency model to ensure that the instructions are in the correct order of the fields. After printing is completed, the printing status is synchronized to the central processing system through a logging and feedback mechanism to achieve closed-loop data management, ensuring the integrity of tasks and the efficiency of processes. This implementation significantly improves the efficiency and accuracy of printing tasks through the optimization of printing frequency modeling and instruction template generation. The calculation of the printing frequency ensures the coordination of synchronized fields, avoiding field loss or incorrect order. Recording the printing log and feeding back the status to the central processing system form a closed-loop management process, further improving 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.

[0047] The status update data synchronized to the nameplate printing terminal in S3 includes the unique identification information of the vehicle, the results of inspection items, and timestamp information. In this implementation, when the vehicle status update data is synchronized to the nameplate printing terminal, it includes the unique identification information of the vehicle, the results of inspection items, and timestamp information. The unique identification information is used to accurately mark the vehicle to ensure that the status data of each vehicle is not confused; the results of inspection items record the detailed results of the PDI inspection, providing a basis for the printed content; the timestamp information ensures the real-time nature of the synchronization process and data tracking capabilities. Through these data, the printing terminal can accurately receive complete and reliable status update information, thus providing support for subsequent printing tasks. The synchronization data design of this implementation is comprehensive and precise, including unique identification information, inspection item results, and timestamp information, significantly improving the reliability and accuracy of data synchronization. The unique identification information ensures the precise positioning of the vehicle status, avoiding data confusion; the inspection item results ensure the accuracy of the content printed on the nameplate; the timestamp information enhances the traceability of the synchronization process, facilitating system troubleshooting and process optimization. This data design not only improves the efficiency of the entire process but also guarantees data integrity and accuracy.

[0048] S4 also includes grouping and processing the generated nameplate printing instructions according to the quantity and content of the vehicle status fields. In this embodiment, grouping and processing the generated nameplate printing instructions according to the quantity and content of the vehicle status fields optimize the execution efficiency of the printing task. Specifically, when the system parses the vehicle status fields, it classifies the printing instructions according to the number of fields, and groups the instructions with similar field numbers or the same field content into one group. Each group of printing tasks can be arranged in order according to the priority or field characteristics, so as to optimize the printing process and avoid waste of device resources. At the same time, the grouping process facilitates task allocation and execution monitoring, further improving the accuracy and efficiency of printing. By grouping and processing the printing instructions, this embodiment achieves higher flexibility and efficiency in the organization and execution of the printing task. The grouping mechanism significantly reduces the conflicts and resource waste of the printing tasks, especially in the multi-task parallel scenario, and improves the utilization rate of the printing device. Grouping by field content and quantity makes the instruction processing more standardized, ensures the accuracy of the printed content, and is convenient for 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 high-efficiency printing requirements in complex production environments.

[0049] In S4, a bar code or a two-dimensional code is attached to the nameplate. In this embodiment, when the nameplate printing instruction is generated, the system parses and encodes the vehicle status data to generate a unique bar code or two-dimensional code for each vehicle. The bar code or two-dimensional code contains the unique identification information of the vehicle, the PDI inspection result, the production batch, and other necessary information. These information are embedded into the bar code or two-dimensional code through an encoding method and attached to the printed nameplate. The generation and printing of the bar code or two-dimensional code can achieve fast data identification and traceability, providing convenience for subsequent logistics management, quality tracking, and maintenance support. The design of attaching the bar code or two-dimensional code significantly enhances the functionality of the nameplate, enabling the relevant information of the vehicle to be quickly obtained through a 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 bar code and two-dimensional code is rich and compact, supporting the system to perform accurate data traceability and management, and meeting the requirements of efficient management in the modern production environment. This additional design also facilitates the subsequent full-process monitoring and traceability, comprehensively improving the intelligent level of production, logistics, and after-sales service.

[0050] The barcodes or QR codes described in S4 include summary information of the vehicle status fields for subsequent verification and traceability. In this embodiment, the summary information of the vehicle status fields is embedded in the barcodes or QR codes, and these information are generated through specific hashing algorithms or data compression technologies to ensure that the key status data of the vehicle are encoded in a concise and complete manner. The summary information generally includes the vehicle identification number, inspection item results, timestamps, and other key fields, which are used to quickly identify and verify the status data of the vehicle. The generated barcodes or QR codes can be decoded by scanning devices, providing fast and reliable data support in subsequent logistics, production verification, and quality traceability processes. This mechanism effectively reduces the redundancy of information transmission, improves the traceability efficiency and accuracy of data. By including the summary information of the vehicle status fields in the barcodes or QR codes, this embodiment further enhances the practicality and efficiency of data. The embedding of the summary information enables the barcodes or QR codes to not only be used to uniquely identify the vehicle but also serve as a direct entry for status data verification and traceability, simplifying the subsequent verification process. Compared with the traditional nameplate design, the introduction of the summary information significantly reduces the verification time, improves the operation 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, especially suitable for production and supply chain management scenarios that require quick response.

[0051] 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 including the unique identification information, inspection item results, and timestamp information of the vehicle, 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 the production batch information during the status update process, the system can more comprehensively reflect the production and inspection process of the vehicle, enhancing the integrity and practicality of the data. The addition of the production batch information significantly enhances the comprehensiveness of data synchronization, enabling the status data of the vehicle to contain more dimensional information and providing strong support for subsequent production management and quality control. The synchronization of the production batch information facilitates the quick positioning of relevant vehicles in case of quality problems or supply chain anomalies, improving the response ability and traceability efficiency of the system. At the same time, this information can generate more accurate nameplate content for the printing terminal, meeting the management needs of different production scenarios, thereby further optimizing the collaborative ability of production and the supply chain.

[0052] The generation of the final print instruction template in S4 also includes additional information fields of the vehicle. In this embodiment, to enhance the flexibility and information integrity of the print instruction template, additional information fields of the vehicle are added when generating the final print instruction template. These additional information fields can include the color of the vehicle, configuration parameters, manufacturing date, warranty information, etc., which are defined and extended according to actual needs. During the process of generating the print instruction template, the system integrates these additional fields with the core status fields and transmits them to the print 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 of the vehicle, the functionality and applicability of the print instruction template are significantly enhanced. The introduction of additional fields not only expands the information scope covered by the nameplate but also meets more diverse production and management requirements. The rich printed content improves the traceability of vehicle information, provides more basis for after-sales service and customer management, and at the same time provides flexibility for customizing the needs of specific markets or customers in nameplate design. In addition, this method can also support the refined operation of production and management links, improving the efficiency and reliability of the overall system.

[0053] The frequency value f of each vehicle status field in S4 i is calculated by the formula: f i = w i × u i ;

[0054] where f i represents the frequency value of each vehicle status field, w i represents the weight of the field, u i represents the priority of the field, and i represents the field number.

[0055] In this embodiment, the frequency value f of the vehicle status field i is calculated by the formula f i = w i × u i where the weight w of the field i is used to reflect the importance of the field in the print instruction, and the priority u of the field i represents the execution order or urgency of the field in the current task. By comprehensively considering the field weight and priority, the calculated frequency value f i can quantify the relative importance of each field in instruction generation. This formula ensures that when generating the print instruction template, different fields are sorted or grouped according to their frequency values to meet the accuracy and timeliness requirements of the print task. This embodiment significantly improves the scientificity and flexibility of print instruction generation by introducing the comprehensive calculation of field weight and priority. The field frequency value fi The dynamic calculation enables the system to flexibly adjust the importance and processing order of fields according to actual requirements, 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.
