[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a method and system for transferring and verifying vehicle configuration on a production line. Background Technology
[0002] Currently, with the development of intelligent manufacturing and flexible production, production lines are increasingly being applied to multi-model mixed-flow production scenarios. In these production lines, intelligent transport vehicles are typically used to transfer flexible conveyor trays equipped with work-in-process (WIP) products between multiple workstations. Different vehicle models correspond to different process sequences and workstation configurations. Therefore, before WIP products enter each workstation, it is necessary to accurately obtain their corresponding vehicle model configuration information and ensure that the tooling configuration and process parameters of each workstation match that vehicle model configuration information.
[0003] In existing technologies, vehicle configuration information is typically distributed by the intelligent transport vehicle scheduling system to relevant control units before work-in-process enters the production line or warehouse, or transmitted to the control systems of subsequent workstations according to task sequence. Each workstation's control system relies on the vehicle configuration information provided by the scheduling system to determine workstation configuration during operation. In this approach, the transmission path for vehicle configuration data is long, and network fluctuations during communication can easily lead to inconsistencies between the vehicle configuration data obtained by the workstation and the actual work-in-process, thus affecting the accuracy of workstation configuration verification.

[0012] As an optional implementation, the target configuration parameters include at least a target tooling identifier and a target process identifier, and the actual configuration parameters include at least the actual tooling identifier and the actual process identifier of the current workstation. The step of comparing the actual configuration parameters with the target configuration parameters to generate a verification result includes: The target tooling identifier is compared with the actual tooling identifier by field comparison; The target process identifier is compared with the actual process identifier by field comparison; If the fields match, the validation passes; otherwise, the validation fails.
[0013] Secondly, a production line vehicle configuration transfer and verification system is provided, including an intelligent transport vehicle scheduling system, intelligent transport vehicles, flexible conveyor brackets, and production line control system PLCs installed at each workstation; wherein... The production line control system PLC at the initial workstation is used to acquire the vehicle configuration data corresponding to the work-in-process when the intelligent transport vehicle enters the initial workstation of the production line, and write the vehicle configuration data into the flexible conveyor tray equipped with the work-in-process. The intelligent transport vehicle dispatching system is used to generate and issue transport tasks based on the vehicle configuration data; The intelligent transport vehicle is used to carry the flexible conveyor bracket to perform the transport task; The flexible conveyor bracket is used to assemble the work-in-process, store the vehicle configuration data of the work-in-process, and move between multiple workstations with the intelligent transport vehicle. The production line control system PLC of the subsequent workstation is used to read the vehicle configuration data from the flexible conveyor bracket after the intelligent transport vehicle enters the corresponding workstation, and to verify and control the workstation configuration status based on the vehicle configuration data.
[0014] As an optional implementation, the production line control system PLC at the initial workstation includes a barcode reading module and a barcode parsing module; wherein, The barcode reading module is used to read the vehicle body barcode information of the work-in-process at the initial work station; The barcode parsing module is used to parse the vehicle body barcode information to obtain the vehicle configuration data.
[0015] As an optional implementation, the flexible transport bracket includes a vehicle configuration storage unit and a communication interface; wherein, The communication interface is connected to the PLC of each production line control system and is used to transmit the vehicle configuration data written by the production line control system PLC of the initial station to the vehicle configuration storage unit at the initial station, and to transmit the vehicle configuration data to the production line control system PLC of the subsequent station at the subsequent station.

The method includes: acquiring vehicle model configuration data corresponding to the work-in-process when an intelligent transport vehicle enters the initial workstation of the production line; writing the vehicle model configuration data into a flexible transport bracket equipped with the work-in-process, so that the vehicle model configuration data of the work-in-process and the flexible transport bracket are bound and stored; controlling the intelligent transport vehicle to carry the flexible transport bracket into multiple target workstations matching the vehicle model configuration data; when the intelligent transport vehicle arrives at any target workstation, reading the vehicle model configuration data from the flexible transport bracket; verifying the configuration status of the current workstation based on the vehicle model configuration data; if the verification fails, controlling the target workstation to perform a configuration switching operation, and performing the verification again after the configuration switching is completed; if the verification passes, controlling the target workstation to perform the corresponding production operation.

By using a bound storage method, vehicle model configuration data establishes a one-to-one correspondence with specific work-in-process (WIP) items from the initial stage of entering the production line. During subsequent transfers, it moves synchronously with the WIP, avoiding information loss or mismatch issues caused by network fluctuations during data transmission. This ensures consistency between vehicle model configuration data and WIP from the data source. By controlling intelligent transport vehicles to carry the flexible conveyor trays into multiple target workstations matching the vehicle model configuration data, the transmission path of the vehicle model configuration data is kept consistent with the physical flow path of the WIP. Subsequently, each target workstation can directly read the vehicle model configuration data from the flexible conveyor tray when it needs to perform workstation configuration checks, without relying on the intelligent transport vehicle scheduling system to send the data. After the intelligent transport vehicle arrives at any target workstation, it verifies the configuration status of the current workstation based on the vehicle model configuration data read from the flexible conveyor tray. If the verification fails, the target workstation is controlled to perform a configuration switching operation. Simultaneously, a verification is performed again after the configuration switching is completed. This avoids directly entering production operations when the workstation configuration and vehicle model configuration do not match, reducing processing anomalies caused by incorrect workstation configurations. In summary, the technical solution of this application achieves the binding and storage of vehicle configuration data with flexible conveyor trays at the initial workstation, and completes workstation configuration verification and control based on the vehicle configuration data transmitted with work-in-process at each target workstation. This enables the vehicle configuration data to form a stable, continuous and verifiable transmission path in the production line, thereby solving the problems of inconsistent configuration caused by vehicle configuration relying on multiple transmissions by the intelligent transport vehicle scheduling system and network issues in the prior art.
[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0021] The following will describe in detail a production line vehicle configuration transfer and verification method provided in this application embodiment, with reference to specific implementation methods. Figure 1 A flowchart of a production line vehicle configuration transfer and verification method provided in this application embodiment is shown below. Figure 1 As shown, the specific steps are as follows: S101 acquires the vehicle configuration data corresponding to the work-in-process when the intelligent transport vehicle enters the initial workstation of the production line.
[0022] In practice, when work-in-process enters the production line, the vehicle model configuration data corresponding to the work-in-process can be obtained through a data acquisition device set up at the initial workstation. For example, a barcode scanner is set up at the initial workstation. After the intelligent transport vehicle arrives, it scans the barcode on the work-in-process vehicle body and retrieves the vehicle model configuration data from the local vehicle model table based on the barcode.
[0023] As an optional implementation, the specific steps in S101 for obtaining the vehicle configuration data corresponding to the work-in-process when the intelligent transport vehicle enters the initial workstation of the production line are as follows: S1011, Read the vehicle body barcode information of the work-in-process.
[0024] In practice, by reading the barcode information on the work-in-process vehicle body, coded information used to identify the unique identity of the work-in-process or vehicle type can be obtained. This code can be used to subsequently determine the vehicle configuration data, allowing the vehicle configuration data to be located when the work-in-process enters the production line. For example, a one-dimensional or two-dimensional barcode scanning device can be set up at the initial workstation. When the intelligent transport vehicle enters the initial workstation and completes its positioning, the scanning device is triggered to read the vehicle body barcode information on the surface of the work-in-process.
[0025] S1012, parse the vehicle body barcode information to obtain vehicle configuration data.
[0026] In implementation, by parsing the vehicle body barcode information, the encoded information carried in the barcode can be mapped to specific vehicle configuration data, transforming the abstract barcode identifier into structured vehicle configuration data. For example, based on the read vehicle body barcode information, the corresponding vehicle configuration data can be searched in a local or pre-configured vehicle configuration database, and the query result can be used as the parsed vehicle configuration data. Another example is that the vehicle body barcode information can be split into fields according to preset encoding rules, extracting information such as the vehicle identification field, version field, and process step information, and combining these fields to generate vehicle configuration data.
[0027] S102, write the vehicle configuration data into the flexible conveyor tray equipped with work-in-process, so that the vehicle configuration data of work-in-process is bound to the flexible conveyor tray for storage.
[0028] In implementation, vehicle model configuration data is written into the flexible conveyor tray, establishing a physical link between the data and work-in-process. This ensures that the vehicle model configuration data is transmitted synchronously during work-in-process transfer, independent of the intelligent transport vehicle scheduling system. For example, vehicle model configuration data can be written into the internal storage module of the flexible conveyor tray via industrial Ethernet. Alternatively, the data can be written into electronic tags installed on the flexible conveyor tray. When the flexible conveyor tray arrives at each workstation, the equipment at that workstation directly reads the electronic tags to obtain the vehicle model configuration data.
[0029] As an optional implementation, before S103, the vehicle configuration data can be segmented and organized to form configuration sub-data segments corresponding to multiple workstations, and the correspondence between the configuration sub-data segment identifier and the workstation identifier can be stored.
[0030] In implementation, by segmenting the vehicle configuration data, configuration content related to different workstations can be distinguished and formed into independent data units. For example, the vehicle configuration data can be divided into multiple configuration sub-data segments, each corresponding to a workstation, and each configuration sub-data segment can be assigned a unique configuration sub-data segment identifier. At the same time, a one-to-one correspondence table between configuration sub-data segment identifiers and workstation identifiers can be established and stored in the production line control system.
[0031] As an optional implementation, after S103, the flexible conveyor can be controlled to switch to the support state corresponding to the work-in-process.
[0032] In implementation, the support state of the flexible conveyor tray can be adapted to the work-in-process (WIP) in terms of geometry, stress location, or support point distribution, thereby ensuring the stability of the WIP during transportation and positioning and avoiding impacts on subsequent processing due to tray mismatch. For example, the flexible conveyor tray can be equipped with multiple sets of switchable support mechanisms. After obtaining the vehicle model configuration data corresponding to the WIP, the production line control system PLC can extract vehicle model information from the configuration data. This extraction process involves identifying the vehicle model identifier field from the configuration data to determine the corresponding vehicle model information for the WIP. The production line control system PLC pre-stores the correspondence between vehicle model information and tray support states, where each support state includes the operational states of multiple support mechanisms. Based on the vehicle model information, the target tray support state can be determined. Based on the target tray support state, the flexible conveyor tray can be controlled to expand or retract the corresponding support mechanisms, switching the flexible conveyor tray to the support state corresponding to that vehicle model.
[0033] S103 controls the intelligent transport vehicle to carry the flexible conveyor tray into multiple target workstations that match the vehicle configuration data.
[0034] In implementation, the process flow path of work-in-process can be controlled based on vehicle model configuration data, ensuring that work-in-process is transported to the target workstation that matches its vehicle model, avoiding the involvement of irrelevant workstations. For example, an intelligent transport vehicle scheduling system can plan transport routes and sequentially dispatch intelligent transport vehicles to the corresponding target workstations based on the preset workstation sequence in the vehicle model configuration data.
[0035] S104: When the intelligent transport vehicle arrives at any target workstation, it reads the vehicle configuration data from the flexible conveyor tray.
[0036] In implementation, by directly reading vehicle model configuration data from the flexible conveyor tray at the target workstation, the workstation can obtain vehicle model information consistent with the current work-in-process, reducing uncertainties arising during vehicle model data distribution. For example, after detecting the arrival signal of the intelligent transport vehicle, the target workstation actively reads the vehicle model configuration data from the flexible conveyor tray's storage module.
[0037] As an optional implementation, the specific steps in S104 for reading vehicle configuration data from the flexible conveyor tray when the intelligent transport vehicle arrives at any target workstation are as follows: S1041, in the correspondence between configuration sub-data segment identifier and workstation identifier, query the target configuration sub-data segment identifier corresponding to the workstation identifier of the target workstation reached by the intelligent transport vehicle.
[0038] In implementation, by pre-establishing the correspondence between configuration sub-data segment identifiers and workstation identifiers, the required configuration sub-data segments for a particular workstation can be quickly determined based on the workstation identifier. This enables targeted acquisition of vehicle configuration data and avoids reading configuration content unrelated to the current workstation. For example, a mapping table can be pre-stored, recording the correspondence between multiple workstation identifiers and their corresponding configuration sub-data segment identifiers. When the intelligent transport vehicle arrives at the target workstation, the corresponding target configuration sub-data segment identifier can be retrieved from the mapping table based on the workstation identifier of that target workstation.
[0039] S1042, based on the target configuration sub-data segment identifier, read the target configuration sub-data segment corresponding to the target workstation from the vehicle configuration data stored in the flexible conveyor bracket.
[0040] In practice, the vehicle configuration data stored in the flexible conveyor can be located and read according to the target configuration sub-data segment identifier, so that the current workstation only obtains the configuration sub-data segments related to itself, thereby improving the targeting of data reading.
[0041] As an optional implementation, the configuration sub-data segment includes at least vehicle identification information and process step sequence information.
[0042] S105 verifies the configuration status of the current workstation based on vehicle configuration data.
[0043] During implementation, the current configuration status of the workstation is compared with the vehicle model configuration data to determine whether the current workstation meets the processing or assembly requirements of the vehicle model.
[0044] As an optional implementation method, the specific steps for verifying the configuration status of the current workstation based on vehicle model configuration data in S105 are as follows: S1051, Get the workstation identifier of the current workstation.
[0045] In practice, after the workstation detects the arrival signal of the intelligent transport vehicle, the workstation identifier of the current workstation can be read from the preset workstation parameters, for example, the workstation identifier is read as ST03.
[0046] S1052, based on the workstation identifier, determines the target configuration parameters corresponding to the current workstation from the vehicle configuration data.
[0047] In practice, by using the workstation identifier as an index condition, target configuration parameters related to the current workstation can be extracted from the vehicle configuration data. For example, using the workstation identifier ST03 as the query condition, the corresponding entry in the vehicle configuration data is searched, and the target configuration parameters are determined to be: target tooling identifier FIX-A2 and target process identifier PROC-110.
[0048] S1053, obtain the actual configuration parameters of the current workstation.
[0049] In practice, the actual configuration parameters of the current workstation can represent the current actual tooling status and process status of the workstation. For example, by reading the tooling number returned by the tooling identification sensor of the current workstation, the actual tooling identifier is obtained as FIX-A1, and by reading the currently loaded process program number, the actual process identifier is obtained as PROC-108.
[0050] S1504 compares the actual configuration parameters with the target configuration parameters and generates a verification result.
[0051] In practice, by comparing the target configuration parameters with the actual configuration parameters, it can be determined whether the current workstation has met the vehicle configuration requirements. For example, the target tooling identifier FIX-A2 can be compared with the actual tooling identifier FIX-A1, and the target process identifier PROC-110 can be compared with the actual process identifier PROC-108 to generate a verification result.
[0052] As an optional implementation, the target configuration parameters include at least the target tooling identifier and the target process identifier, and the actual configuration parameters include at least the actual tooling identifier and the actual process identifier of the current station. The specific steps in S1054 to compare the actual configuration parameters with the target configuration parameters and generate the verification result are as follows: The target tooling identifier is compared with the actual tooling identifier by field, and the target process identifier is compared with the actual process identifier by field. If the fields match, the verification passes; otherwise, the verification fails.
[0053] In implementation, the tooling identifier field and the process identifier field can be verified separately through field comparison. For example: if the tooling identifier is FIX-B1 and the actual tooling identifier is FIX-B1, and the target process identifier is PROC-205 and the actual process identifier is PROC-205, and both fields match, a verification pass result is generated. However, if the target tooling identifier FIX-A2 does not match the actual tooling identifier FIX-A1, and the target process identifier PROC-110 does not match the actual process identifier PROC-108, a verification fail result is generated.
[0054] S106 If the verification fails, control the target workstation to perform a configuration switch operation, and perform the verification again after the configuration switch is completed.
[0055] In implementation, when the verification results indicate that the workstation configuration does not meet the vehicle model requirements, a configuration switching operation can be performed at the workstation to adjust its status to match the vehicle model configuration data. After the switch, the configuration status is reconfirmed to prevent direct entry into the work process if the switch fails. For example, the workstation can be controlled to perform a tooling switch action; after the switch completion signal is triggered, the current tooling number is reread and verification is performed again. Alternatively, the workstation can be controlled to load the process program corresponding to the vehicle model configuration data; after the program is loaded, the configuration status verification is performed again.
[0056] S107 If the verification passes, control the target workstation to execute the corresponding production operation.
[0057] In practice, production operations are allowed at workstations if the verification is passed.
[0058] As an optional implementation method, Figure 2 A flowchart illustrating an example of a production line vehicle configuration transfer and verification method provided in this application embodiment is shown below. Figure 2 As shown, the specific steps are as follows: S201, the intelligent transport vehicle enters the initial workstation; S202, Initial workstation writes vehicle configuration data to the flexible conveyor bracket of the intelligent transport vehicle; S203, the intelligent transport vehicle scheduling system receives the vehicle configuration data of the initial workstation and plans the task path of the intelligent transport vehicle.
[0059] S204, the intelligent transport vehicle arrives at other subsequent workstations. S205, reads the vehicle configuration data of the flexible transport bracket.
[0060] S206 verifies the configuration status of the current workstation based on vehicle configuration data.
[0061] This application provides a method for transferring and verifying vehicle configuration on a production line, which has the following advantages: When the intelligent transport vehicle enters its initial workstation on the production line, it acquires the vehicle model configuration data corresponding to the work-in-process (WIP) and writes this data into a flexible conveyor tray equipped with the WIP, thus creating a bound storage system between the vehicle model configuration data and the flexible conveyor tray. This bound storage establishes a one-to-one correspondence between the vehicle model configuration data and the specific WIP item from the very beginning of production. During subsequent transfers, the data moves synchronously with the WIP item, avoiding information loss or mismatch issues caused by network fluctuations. This ensures consistency between the vehicle model configuration data and the WIP item from the data source. By controlling the intelligent transport vehicle to carry the flexible conveyor tray to multiple target workstations matching the vehicle model configuration data, the transmission path of the vehicle model configuration data is kept consistent with the physical flow path of the WIP item. Subsequently, each target workstation can directly read the vehicle model configuration data from the flexible conveyor tray when it needs to perform workstation configuration checks, without relying on the intelligent transport vehicle scheduling system to send the vehicle model configuration data. After the intelligent transport vehicle arrives at any target workstation, the configuration status of the current workstation is verified based on the vehicle configuration data read from the flexible conveyor. If the verification fails, the target workstation is controlled to perform a configuration switching operation. Simultaneously, after the configuration switching is completed, verification is performed again. This avoids directly entering production when the workstation configuration and vehicle configuration do not match, reducing processing anomalies caused by incorrect workstation configurations. In summary, the technical solution of this application achieves the binding and storage of vehicle configuration data with the flexible conveyor at the initial workstation, and completes workstation configuration verification and control at each target workstation based on the vehicle configuration data transferred along with work-in-process. This enables the vehicle configuration data to form a stable, continuous, and verifiable transmission path in the production line, thereby solving the problems of vehicle configuration relying on multiple transfers by the intelligent transport vehicle scheduling system and configuration inconsistencies caused by network issues in existing technologies.
[0062] It should be understood that, although Figures 1 to 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1 to 2 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.
[0063] The following will describe in detail, with reference to specific implementation methods, a production line vehicle configuration transfer and verification system provided in this application embodiment. Figure 3This application provides a schematic diagram of the structure of a production line vehicle configuration transfer and verification system, as shown in the embodiments. Figure 3 As shown, the system includes an intelligent transport vehicle scheduling system 110, an intelligent transport vehicle 120, a flexible conveyor frame 130, and 14X1 (1401, 1411, 1421...) production line control system PLCs (Programmable Logic Controllers) installed at each workstation 14X (140, 141, 142...); among which, The production line control system PLC1401 of the initial station 140 is used to obtain the vehicle configuration data corresponding to the work-in-process when the intelligent transport trolley 120 enters the initial station 140 of the production line, and write the vehicle configuration data into the flexible conveyor tray 130 equipped with the work-in-process. The intelligent transport vehicle dispatching system 110 is used to generate and issue transport tasks based on vehicle configuration data. The intelligent transport vehicle 120 is used to carry the flexible conveyor bracket 130 to perform transport tasks; The flexible conveyor 130 is used to assemble work-in-process, store the vehicle configuration data of the work-in-process, and move between multiple workstations with the intelligent transport trolley 120. The production line control system PLCs (1411, 1421, 1431...) of subsequent workstations (141, 142, 143...) are used to read vehicle configuration data from the flexible conveyor tray 130 after the intelligent transport vehicle 120 enters the corresponding workstation, and to verify and control the workstation configuration status based on the vehicle configuration data.
[0064] As an optional implementation, the production line control system PLC 1401 at the initial workstation includes a barcode reading module and a barcode parsing module; wherein, The barcode reading module is used to read the vehicle body barcode information of the work-in-process at the initial workstation 140; The barcode parsing module is used to parse the vehicle body barcode information to obtain vehicle configuration data.
[0065] As an optional implementation, the flexible transport bracket 130 includes a vehicle configuration storage unit and a communication interface; wherein, The communication interface is connected to the PLC of each production line control system and is used to transmit the vehicle configuration data written by the production line control system PLC of the initial station to the vehicle configuration storage unit at the initial station, and to transmit the vehicle configuration data to the production line control system PLC of the subsequent station at the subsequent station. The vehicle configuration storage unit is used to store the vehicle configuration data of the work-in-progress in a read-write manner.
[0066] In implementation, by setting up an independent vehicle configuration storage unit on the flexible conveyor tray 130 and establishing a communication connection with the production line control system PLC via a communication interface, vehicle configuration data can be written to the flexible conveyor tray 130 for storage at the initial workstation by the production line control system PLC. At subsequent workstations, the corresponding production line control system PLC can directly read the data from the flexible conveyor tray 130. This allows the vehicle configuration data to be synchronously transferred along with the work-in-process, avoiding repeated distribution or transfer of vehicle configuration data between multiple workstations. For example, a non-volatile memory can be installed within the flexible conveyor tray 130 as the vehicle configuration storage unit, with an industrial Ethernet interface. After detecting the arrival of the intelligent transport vehicle, the production line control system PLC at the initial workstation can write the vehicle configuration data to the non-volatile memory via the industrial Ethernet.
[0067] Optionally, the vehicle configuration storage unit can also be equipped with electronic tags on the flexible conveyor tray 130. At the initial station, the production line control system PLC writes the vehicle configuration data into the electronic tag. When the flexible conveyor tray 130 carries the work-in-process to the subsequent station, the production line control system PLC of the corresponding station reads the vehicle configuration data through the electronic tag reader / writer, realizing the acquisition of vehicle configuration data between different stations.
