Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing and processing technology, and in particular to a management system, management method, equipment and storage medium for a vehicle production line. Background Technology

[0002] In the vehicle manufacturing process, painting and final assembly lines undertake core processes such as exterior processing, structural assembly, and functional debugging, and are key links in ensuring vehicle quality and production efficiency. With the accelerated pace of product iteration and the diversification of vehicle configurations, multi-model mixed-line production has become the mainstream trend in the industry. Different models and configurations of vehicles flow on the same production line, which places extremely high demands on the precise control of the production process.

[0003] Traditional vehicle production line management solutions typically employ a distributed control architecture: each process device in the production line, such as painting robots, adhesive application equipment, and conveyor lines, communicates independently with the MES (Manufacture Execution System) and independently queries the vehicle's configuration information and matches the processing program based on the vehicle's VIN (vehicle identification number).

[0004] However, due to the high coupling between the process equipment and the MES, upgrading the MES and adjusting its interfaces require simultaneous modification of the control logic of all process equipment, resulting in high system maintenance costs and poor scalability. Furthermore, when adding new models or adjusting configurations, the processing programs of each process piece must be modified individually, impacting production efficiency.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] In production scenarios involving mixed production of multiple vehicle models and transfer between different production lines, the traditional distributed control architecture, where each process equipment, such as painting robots, gluing equipment, and conveyor lines, communicates independently with the MES, queries the configuration information in the MES based on the vehicle's VIN, and then matches the corresponding processing program locally on the process equipment based on the queried configuration information, and then performs production processing on the vehicle according to the matched processing program.

[0029] However, the aforementioned distributed control architecture suffers from problems such as poor system flexibility, high production costs, and low production efficiency. Specifically, traditional distributed control architectures have the following issues: First, the coupling between process equipment and the MES is high. When the MES system is upgraded or interfaces are adjusted, the communication interfaces of all process equipment must be modified simultaneously, resulting in high system maintenance costs and poor scalability. Second, because vehicle configuration information is deeply bound to the processing programs of process equipment, each process equipment independently matches its processing program locally based on the vehicle's configuration information. When a new vehicle model is added or its configuration is adjusted, the program logic used to match the processing program in each process equipment must be modified one by one. Third, there is a lack of a unified fallback mechanism for exceptions. In abnormal scenarios such as MES communication interruption or electronic tag reading failure, production line shutdowns can easily occur, affecting production cycle time.

[0030] In view of this, embodiments of this application provide a vehicle production line management system, the system comprising: a control unit configured to acquire a first identification code of a target vehicle and send the first identification code to a first server; a first server configured to determine first configuration information and first process information of the target vehicle based on the first identification code, and send the first configuration information and first process information to the control unit, wherein the first configuration information is used to indicate the processing requirements of the target vehicle, and the first process information is used to indicate the processing information corresponding to the processing requirements of the target vehicle; the control unit is further configured to, upon receiving the first configuration information and first process information, write the first configuration information and first process information into a first electronic tag of the target vehicle, wherein the first electronic tag is read by multiple process devices in the vehicle production line, so that the multiple process devices can perform identity verification of the target vehicle based on the first configuration information, and can perform processing of the target vehicle based on the first process information.

[0031] The vehicle production line management system provided in this application embodiment, through centralized information control, allows the control unit to uniformly obtain the first configuration information and first process information of the target vehicle from the first server and simultaneously write both into the first electronic tag. This decouples the control unit, the first server, and each process equipment, greatly simplifies the program logic of each process equipment, improves the flexibility of the production line, ensures the consistency and accuracy of information during the vehicle's flow on the production line, guarantees precise control of the production process, adapts to the needs of mixed production of multiple vehicle models, and improves the flexibility and production efficiency of the production line.

[0032] Figure 1 is a schematic diagram of the structure of the vehicle production line management system provided in an embodiment of this application. Referring to Figure 1, the vehicle production line management system provided in an embodiment of this application includes a control unit 110 and a first server 120.

[0033] It should be noted that the vehicle production line in this application embodiment may be a painting production line, welding production line, or final assembly production line, etc. This application does not impose any restrictions in this regard. The following will take the painting production line as an example to further explain the vehicle production line management system provided in this application embodiment.

[0034] In some embodiments, the coating production line includes, for example, multiple process devices and the management system shown in Figure 1. These multiple process devices are used for, but are not limited to, processing operations on the target vehicle such as electrophoresis, spraying, adhesive application, waxing, drying, conveying, and / or inspection. These multiple process devices include, for example, one or more of the following: conveying equipment, electrophoretic rectifier equipment, ISS (Integrated Sealing System) robot, UBS (Under Body Sealing) robot, UBC (Under Body Coating) robot, LASD (Liquid Applied Sound Deadener) robot, RPP (Robotic Paint Process) robot, paint robot, cleaning robot, and waxing equipment. This application makes no limitation in this regard.

[0035] The management system communicates with multiple process devices via wired or wireless means, and is used, but not limited to, issuing control commands to multiple process devices, obtaining the operating status of multiple process devices, verifying relevant information of target vehicles, and uniformly managing the production process.

[0036] Control unit 110 is configured to acquire the first identification code of the target vehicle and send the first identification code to the first server 120.

[0037] For example, the target vehicle is any type of vehicle currently entering the painting production line for processing. The first identification code of the target vehicle is, for example, a VIN (Vehicle Identification Number) or any other type of identification code that can uniquely identify the target vehicle, so that all production information and configuration information of the target vehicle can be uniquely indexed based on the vehicle's first identification code.

[0038] Optionally, the vehicle's first identification code may be obtained by the control unit 110 through data interaction with the conveyor equipment in the painting production line. For example, when the target vehicle enters the painting production line, the barcode reader mounted on the conveyor equipment scans the vehicle's body barcode to obtain the target vehicle's first identification code; then, the conveyor equipment sends the first identification code to the control unit 110.

[0039] Considering that in practical applications, if the barcode reader malfunctions or the vehicle body barcode is severely damaged, the first identification code acquisition may fail. In this case, the control unit 110 is also configured to generate a third warning message through multiple process devices if the first identification code acquisition fails, prompting relevant personnel on the painting production line to manually input the target vehicle's first identification code via the conveyor equipment. For example, the control unit 10 may issue a warning light through the conveyor equipment in multiple process devices.

[0040] Furthermore, considering that in practical applications, the direct point-to-point communication between the control unit 110 and the first server 120 results in strong coupling and high maintenance costs—for example, if either the control unit 110 or the first server 120 needs to upgrade its interface, change its protocol, or adjust its data format, the other party also needs to adapt and modify accordingly—or, when there are multiple parallel vehicle production lines directly connected to a network via a first server 120 and multiple control units 110, the wiring becomes complex, expansion is difficult, and management costs are high. Therefore, in some embodiments, the control unit 110 and the first server 120 communicate via IoT (Internet of Things), for example, by transmitting the first identification code to the first server 120 through IoT, thereby improving the flexibility and scalability of the management system.

[0041] The first server 120 is configured to determine the first configuration information and the first process information of the target vehicle based on the first identification code, and send the first configuration information and the first process information to the control unit 110. The first configuration information indicates the processing requirements of the target vehicle, and the first process information indicates the processing information corresponding to the processing requirements of the target vehicle.

[0042] For example, the first configuration information of the target vehicle is, for instance, the configuration information of the target vehicle determined by the first server 120 based on the first identification code. The configuration information of the target vehicle refers to a set of various parameters used to characterize the vehicle's own attributes, structural features, and production requirements, used, but not limited to, indicating the vehicle's processing needs; the configuration information differs for different vehicles.

[0043] The first process information of the target vehicle is, for example, the process information of the target vehicle determined by the first server 120 based on the first configuration information. Here, process information refers to processing information that matches the vehicle's configuration information, that is, processing information that matches the vehicle's processing requirements, used, but not limited to, converting the processing requirements indicated by the vehicle's configuration information into processing operations that can be performed by multiple process devices.

[0044] In different vehicle production lines, due to differences in processing objects, process requirements, and control dimensions, the information dimensions of vehicle configuration information also differ. For example, in a painting production line, vehicle configuration information may include, but is not limited to, one or more parameters from information dimensions such as main model, model modification, sunroof type, powertrain, number of seats, left- or right-hand drive, body panels, high-gloss film, 48V, exterior color, clear coat type, production type, and sales location. This application does not impose any restrictions in this regard.

[0045] Within the same vehicle production line, different vehicles may have the same or different processing requirements when their configuration information differs. For example, in a painting production line, if vehicle A and vehicle B differ in at least one of the following parameters: main model, model modification, sunroof type, powertrain, number of seats, left / right drive, body panels, high-gloss film, 48V, exterior color, clear coat type, production type, and sales location, then the processing requirements for vehicles A and B may be the same or different, and their corresponding process information may also be the same or different. If all parameters in these four dimensions differ, then the processing requirements and corresponding process information for vehicles A and B will also differ.

[0046] Optionally, the configuration information of the target vehicle may be configured locally on the first server 120, or on a second server that is communicatively connected to the first server 120.

[0047] When the configuration information of the target vehicle is configured locally on the first server, the first server 120 may store multiple configuration information corresponding to the identification codes of different vehicles. The first server 120 is configured to: determine the first configuration information corresponding to the first identification code among the multiple configuration information; query the first mapping table according to the first configuration information; and determine the first process information according to the query result of the first mapping table.

[0048] When the configuration information of the target vehicle is configured on the second server, the second server stores multiple configuration information that correspond one-to-one with the identification codes of different vehicles. The first server 120 is configured to: request the first configuration information from the second server according to the first identification code; upon receiving the first configuration information, query the first mapping table according to the first configuration information, and determine the first process information according to the query result of the first mapping table.

[0049] The first mapping table is a set of mapping relationships between different configuration information and different process information. It is used, but not limited to, to output the corresponding process information based on the input configuration information, such as outputting the first process information based on the input first configuration information.

[0050] As mentioned earlier, the process information is used to transform the processing requirements indicated by the vehicle's configuration information into processing operations that can be executed by multiple process devices. That is, the processing requirements indicated by the first configuration information need to be completed collaboratively by multiple process devices performing corresponding processing operations. In this case, there are multiple first mapping tables and multiple first process information sets. These multiple first mapping tables, multiple first process information sets, and multiple process devices correspond one-to-one, enabling the first server 120 to independently match and generate the corresponding first process information for different process devices, thus achieving refined and differentiated process control.

[0051] As mentioned earlier, vehicle configuration information includes multiple information dimensions; that is, the first configuration information is a set of various parameters of the target vehicle under multiple information dimensions. Considering that in practical application scenarios, the information dimensions of the configuration information required to refer to the first process information corresponding to different process equipment are different, when querying the first mapping table corresponding to each process equipment, only some parameters corresponding to the information dimensions related to that equipment in the first configuration information need to be used, rather than all configuration information.

[0052] In this case, the first server 120 is configured to: determine the target information related to each process device in the first configuration information for each process device; query the first mapping table corresponding to each process device according to the target information; and determine the first process information corresponding to each process device according to the query result of the first mapping table corresponding to each process device.

[0053] The first mapping table for each process device is a set of mapping relationships between different target information and different process information for each process device. It is used, but not limited to, to output the corresponding process information based on the input target information. For example, it outputs the first process information corresponding to each process device based on the target information related to each process device in the first configuration information.

[0054] Figure 2 This is a process configuration relationship mapping table provided in the embodiments of this application.

[0055] The following will combine Figure 2 Table 1 further explains the process of determining the first process information corresponding to each process equipment.

[0056] like Figure 2As shown, the first configuration information includes parameters from multiple dimensions such as the main model, model facelift, sunroof type, power type, number of seats, left-hand drive or right-hand drive, body guard plate, high-gloss film, 48V, exterior color, clear coat type, production type, and sales location.

[0057] When querying multiple first mapping tables, the information dimensions of the configuration information required by different process equipment are related to the process control requirements and action types of that equipment. That is, the information dimensions of the configuration information required by each process equipment when querying its corresponding first mapping table may differ. In this case, the target information for each process equipment may include parameters of at least one information dimension, and the information dimensions corresponding to the target information of different process equipment may differ. For example, the target information of an electrophoretic rectifier equipment is formed by a combination of parameters from two information dimensions: main vehicle model and model modification; the target information of an ISS robot is formed by a combination of parameters from five sub-information dimensions: main vehicle model, model modification, power type, number of seats, and left / right steering.

[0058] In some embodiments, the first server 120 determines the target information related to each process device in the first configuration information by, for example, querying. Figure 2 The process configuration relationship mapping table is shown. This table indicates the mapping relationship between the type of process equipment and the corresponding information dimension combination of the target information, and is used, but not limited to, to output the information dimension corresponding to the target information of the process equipment based on the input type of process equipment.

[0059] As shown in Table 1, in some embodiments, each process device corresponds to a predefined set of actions, which includes multiple actions, indicating the range of actions that each process device can perform.

[0060] Table 1

[0061] In this case, the different target information in the first mapping table corresponding to each process equipment is, for example, target information with the same information dimension but different values ​​for parameters of at least one information dimension; the different process information in the first mapping table corresponding to each process equipment is multiple actions in the action set of each process equipment.

[0062] Based on this, the first process information corresponding to each process device is, for example, the action in the action set of each process device that matches the target information of each process device. That is, when querying the corresponding first mapping table according to the target information related to each process device in the first configuration information, the query result output by the first mapping table is, for example, the action in the action set of each process device that matches the target information of each process device. For example, when the process device is a robot, the multiple actions corresponding to the robot are mapped to different target information, such as contouring 1 mapped to target information 1, contouring 2 mapped to target information 2, ..., contouring N mapped to target information N. If the target information related to the robot in the first configuration information of the target vehicle to be processed is target information 1, then the first process information of the target vehicle at the robot is the robot performing the contouring 1 action.

[0063] For example, in the first mapping table corresponding to the paint robot, each record corresponds to target information formed by parameters from five information dimensions: main vehicle model, model modification, sunroof type, powertrain type, and exterior color, as well as the corresponding action number and device number. The first server 120 extracts the target information formed by the parameter combination of the five information dimensions (main vehicle model, model modification, sunroof type, powertrain type, and exterior color) from the first configuration information, and uses this target information combination as the query condition to query the corresponding first mapping table.

[0064] During the query process, the first server 120 traverses all rows of different target information in the first mapping table and matches them with the target information extracted from the first configuration information. When the target information of a certain row is completely consistent with the target information extracted from the first configuration information, the match is successful, and the action sequence number and equipment sequence number corresponding to that row are determined as the first process information of each process equipment.

[0065] Optionally, after determining the first configuration information and the first process information, the first server 120 packages the first configuration information and multiple sets of first process information, adds a data checksum, and sends it to the control unit 110. The data checksum, for example, is a CRC (Cyclic Redundancy Check) checksum, used, but not limited to, to ensure the accuracy of data transmission.

[0066] Figure 3 This is another process configuration relationship mapping table provided in the embodiments of this application.

[0067] Considering that in practical application scenarios, some processing operations in vehicle production lines require manual selection, manual assembly, or manual error prevention verification, such as the pretreatment electrophoresis fixture selection, asphalt board selection, and film decoration in various painting processes shown in Figure 3, in some embodiments, the process configuration relationship mapping table includes, for example, a first process configuration relationship mapping table and a second process configuration relationship mapping table. The first process configuration relationship mapping table is, for example, the process equipment management table shown in Figure 2, used, but not limited to, outputting the information dimension corresponding to the target information of the input process equipment based on the type of the process equipment, so that the process equipment can automatically match and execute the corresponding processing operation based on the corresponding information dimension. The second process configuration relationship mapping table is, for example, the manual error prevention management table shown in Figure 3, used, but not limited to, outputting the information dimension corresponding to the target information of the manual workstation / manual selection process based on the type of the input process equipment, so that the manual workstation can perform selection, assembly, or error prevention verification based on the corresponding information dimension.

[0068] The control unit 110 is further configured to, upon receiving first configuration information and first process information, write the first configuration information and first process information into a first electronic tag of the target vehicle. The first electronic tag is read by multiple process equipment in the vehicle production line, so that the multiple process equipment can verify the identity of the target vehicle based on the first configuration information and process the target vehicle based on the first process information.

[0069] For example, the first electronic tag of the target vehicle is, for example, an RFID (Radio Frequency Identification) tag, a barcode tag, a QR code tag, or any other type of information carrier that can store and allow the device to read the first identification code, the first configuration information, and the first process information.

[0070] Optionally, the method by which the control unit 110 writes the first configuration information and the first process information into the first electronic tag of the target vehicle is, for example, that the control unit 110 sends a tag writing instruction to the conveying equipment, the instruction carrying the first configuration information and the first process information. After receiving the instruction, the conveying equipment writes the first configuration information and the first process information into the first electronic tag of the target vehicle.

[0071] In some embodiments, after receiving the first configuration information and the first process information, the control unit 110 stores the first configuration information, the first process information, and the first identification code in a local cache module. The cache validity period covers, for example, the entire processing cycle of the target vehicle on the vehicle production line, for subsequent workstation verification and anomaly fallback.

[0072] Optionally, after the first electronic tag is written, the conveying equipment returns a successful writing confirmation command to the control unit 110. In response to the successful writing confirmation command, the control unit 110 controls the conveying equipment to read the first electronic tag and performs a consistency check between the reading result of the first electronic tag and the locally cached first configuration information and first process information. If the consistency check passes, the vehicle is allowed to enter the next processing station in the vehicle production line. If the consistency check fails, an early warning is triggered and the writing operation of the first electronic tag is re-executed to ensure the accuracy of the data in the electronic tag.

[0073] In some embodiments, the control unit 110 is further configured to: receive a second identification code, which is sent after scanning the identification of the vehicle to be processed at any of the multiple process equipments; if the first identification code and the second identification code are inconsistent, suspend the vehicle production line and generate a first warning message, which is used to indicate that there is an identification code abnormality problem in the vehicle production line.

[0074] In this scenario, when the target vehicle arrives at any processing station of the equipment, the equipment scans the vehicle's identification code (VIN) using an integrated scanning device. This second identification code is identical to the first identification code. The equipment then sends the scanned second identification code to the control unit 110. Upon receiving the second identification code, the control unit 110 performs a consistency comparison with the locally cached first identification code.

[0075] If the first identification code matches the second identification code, it indicates that the vehicle to be processed at any process equipment is the same vehicle as the target vehicle, the identity verification at any process equipment passes, and the processing operation at any process equipment is allowed. If the first identification code does not match the second identification code, it indicates that the vehicle to be processed at any process equipment is not the same vehicle as the target vehicle, the identity verification at any process equipment fails, the control unit 110 immediately suspends the vehicle production line, and generates a first warning message through the human-machine interface, audible and visual alarm devices, etc., in the vehicle production line, indicating that there is an identification code abnormality problem in the production line, such as mixed vehicles, VIN scanning error, label tampering, etc., and notifies on-site technicians to investigate and handle it.

[0076] After technicians completed the troubleshooting and confirmed that the anomaly had been eliminated, they reset the vehicle production line through the human-machine interface of the control unit 110, restoring vehicle production operation. This identification code consistency verification mechanism can effectively prevent problems such as vehicle and information mismatch and mixed vehicles, improving the error prevention capability of the production line.

[0077] In other embodiments, the control unit 110 is further configured to: receive instructions for second configuration information and second process information, wherein the second configuration information and second process information are sent by any of the multiple process devices after reading the second electronic tag of the vehicle to be processed at any of the process devices; if the first configuration information and the second configuration information are inconsistent, and / or the first process information and the second process information are inconsistent, then suspend the vehicle production line and generate a second warning message, wherein the second warning message is used to indicate that there is an abnormal processing information problem in the vehicle production line.

[0078] In this scenario, when the target vehicle arrives at the processing station of any processing equipment, that equipment reads the second configuration information and second process information from the electronic tag of the vehicle to be processed, i.e., the configuration information and process information stored in the tag, and sends the second configuration information and second process information to the control unit 110. After receiving the second configuration information and second process information, the control unit 110 performs a consistency comparison with the first configuration information and first process information cached locally.

[0079] If the first configuration information matches the second configuration information, and the first process information matches the second process information, then the identity verification passes, allowing any process equipment to perform processing operations. If any information is inconsistent, such as the first configuration information and the second configuration information not matching, the first process information and the second process information not matching, or the first configuration information and the second configuration information not matching, and the first process information and the second process information not matching, then the identity verification fails. The control unit 110 immediately suspends the vehicle production line, generates a second warning message, indicating that there is an abnormal processing information problem in the production line, such as label writing error, data tampering, program matching error, etc., and notifies on-site technical personnel to investigate and handle the issue.

[0080] After technicians complete the troubleshooting, they confirm the cause of the anomaly. If tag writing fails, it is rewritten; if the program matching error occurs, the process information is re-requested. Once the anomaly is resolved, the production line is reset, and production resumes. This configuration-process information consistency verification mechanism effectively prevents problems such as abnormal electronic tag reading and writing, data tampering, and program matching errors, further improving the production line's error prevention capabilities and processing accuracy.

[0081] In some other embodiments, the control unit 110 is further configured to: acquire third configuration information and third process information of the target vehicle when the first configuration information and first process information are not received, wherein the third configuration information and third process information are input by on-site technicians of the vehicle production line; write the third configuration information and third process information into a second electronic tag of the target vehicle, wherein the second electronic tag is read by multiple process devices in the vehicle production line, so that the multiple process devices can verify the identity of the target vehicle according to the third configuration information, and process the target vehicle according to the third process information.

[0082] In this scenario, if the control unit 110 does not receive the first configuration information and first process information within a preset time, such as 30 seconds, after sending the first identification code to the first server 120, it determines that the data acquisition is abnormal and triggers the fallback procedure. The control unit 110 prompts the on-site technician through the human-machine interface, requesting the input of the third configuration information and third process information of the target vehicle. The on-site technician manually inputs the third configuration information and third process information based on the vehicle production order, configuration list, and other materials, and submits them to the control unit 110. The control unit 110 verifies the format validity of the third configuration information and third process information input by the technician. After successful verification, the control unit writes the third configuration information and third process information into the second electronic tag of the target vehicle.

[0083] In this case, the second electronic tag and the first electronic tag may be the same information carrier, but the data sources may differ.

[0084] Optionally, when the target vehicle is transported to the corresponding processing station of each process equipment, the process equipment reads the first configuration information and first process information from the first electronic tag through an integrated tag reading module. The process equipment verifies the identity of the target vehicle based on the read first configuration information. For example, it compares key information in the first configuration information, such as the main vehicle model, exterior color, and VIN code, with the actual status of the vehicle to confirm that the vehicle's identity matches the processing requirements, thus avoiding mixed-vehicle processing. If the identity verification passes, the process equipment executes the processing operations for the target vehicle based on the read first process information, such as paint spraying, clear coat spraying, adhesive application, and conveyor control.

[0085] Optionally, after the processing operation of the target vehicle is completed, each process equipment will feed back the processing status, such as success or failure, to the control unit 110, so that the control unit 110 can update the production status of the target vehicle according to the processing status of the target vehicle, realize full traceability of the production process, and facilitate subsequent quality control and after-sales investigation.

[0086] Figure 4 This is a schematic diagram of the architecture of the vehicle production line management system provided in this application embodiment.

[0087] Figure 5 This is a data interaction diagram of the vehicle production line management system provided in this application embodiment.

[0088] like Figure 4 and Figure 5 As shown in the embodiments of this application, the architecture of the vehicle production line management system includes: The data management layer, also known as the first server mentioned above, is, for example, the Manufacturing Execution System (MES). The MES is used, but is not limited to, managing business data within the vehicle production line. For instance, the MES is configured with process configuration relationship mapping tables as shown in Figures 2 and 3, as well as multiple first mapping tables, enabling unified maintenance of vehicle configuration information and process information, management of mapping relationships, and full-process data control. When maintenance of business data within the vehicle production line is required, modifications to the relevant MES configurations can complete a unified update of the process rules across the entire production line, eliminating the need for individual adjustments to on-site equipment.

[0089] The data application layer, namely the aforementioned control unit, also known as the central control system in the vehicle production line, such as the painting central control system, is used, but is not limited to, receiving vehicle identity information collected by field equipment, requesting matching process information from the data management layer, issuing processing instructions to field equipment, and realizing centralized monitoring and scheduling of the production process on the production line.

[0090] The data transmission layer, such as an IoT platform, is used, but not limited to, as a data transmission channel between the MES and the painting control system, to enable highly reliable, low-latency data interaction between the data management layer and the data application layer, and to ensure bidirectional transmission and synchronization of VIN information, configuration information, and process information.

[0091] The equipment control layer, namely the aforementioned multiple process equipment, is used, but is not limited to, to perform data acquisition, reading and writing operations. For example, RFID reading and writing and VIN scanning equipment controlled by the conveyor equipment PLC (Programmable Logic Controller) are used to complete vehicle identity information collection, and coating processing operations are performed by coating equipment such as glue-applying robots and spraying robots.

[0092] The aforementioned architecture, through its layered and decoupled design logic, decouples different architectural layers such as the data management layer, data transmission layer, data application layer, and equipment control layer. Each layer has clearly defined responsibilities and evolves independently. For example, the equipment control layer is responsible for collecting, reading, writing, and uploading data from the production site to the central control system. The central control system, based on the VIN and other identity information collected from the site, requests the corresponding configuration and process information from the data management layer and distributes the process information to the equipment control layer. This allows the data management layer to focus on the unified management of business rules and data without directly interfacing with field equipment, thus improving the system's maintainability and scalability.

[0093] Figure 6 This is another data interaction diagram of the vehicle production line management system provided in this application embodiment.

[0094] like Figure 6 As shown, another data interaction example of the vehicle production line management system includes: Process Startup and VIN Acquisition: After the program starts, the field device PLC, i.e., multiple process devices, performs a hardware scanning operation to acquire the VIN code of the target vehicle. If the VIN is successfully read, the Ready signal is set to true.

[0095] Data Request and Transmission: The central control system converts the VIN data and sends it to the IOT / MES to complete the VIN reporting and data request; the IOT / MES receives the VIN, processes it, and confirms whether to return the data.

[0096] Data Confirmation and Distribution: If the IOT / MES does not return data, the central control system triggers a hardware alarm on the field equipment and displays the alarm screen on the corresponding interface; if the IOT / MES confirms the return of data, the central control system distributes data to the field equipment PLC, such as the target vehicle's first configuration information and first process information. Vehicle information and configuration data.

[0097] Data transmission verification and anomaly handling: If the data transmission from the central control system is successful, the conveyor in the field equipment PLC will write the data to the electronic tag. Upon reaching the corresponding workstation, the PLC of the coating equipment at that workstation will read the electronic tag and perform identity verification. After successful verification, the interface data and confirmation signal will be cleared, and the process will end. If the data transmission from the central control system fails, a hardware alarm will be triggered and displayed on the corresponding interface.

[0098] Forced release mechanism: For abnormal scenarios that occur in the process (such as data transmission failure, alarms, etc.), the central control system supports forced release operation: After on-site personnel investigate the cause, provide feedback to IOT / MES processing, and input the production plan, the abnormal steps can be skipped to complete the process, ensuring continuous production on the production line.

[0099] The technical solution provided in this application, through a centralized control architecture centered on the control unit, achieves multi-layered decoupling between the control unit, the first server, and the field process equipment. This results in clear responsibilities for each module, low system maintenance costs, and strong scalability. For example, the first server centrally matches the first configuration information with the first process information, avoiding the mismatch risk inherent in traditional decentralized matching methods. The control unit synchronously writes the first configuration information and the first process information into the first electronic tag, allowing the process equipment to directly read the electronic tag to complete identity verification and processing execution. This reduces communication pressure, improves production stability, and enables the process equipment to simultaneously complete the identity verification and processing operations of the target vehicle, effectively avoiding problems such as mixed vehicles and incorrect processing, and enhancing the error prevention capability of the production line.

[0110] In some possible implementations, the method further includes: acquiring third configuration information and third process information of the target vehicle in the absence of receiving first configuration information and first process information, wherein the third configuration information and third process information are information input on-site at the vehicle production line; writing the third configuration information and third process information into a second electronic tag of the target vehicle, wherein the second electronic tag is read by multiple process devices, so that the multiple process devices can verify the identity of the target vehicle according to the second configuration information, and process the target vehicle according to the second process information.
