[0048] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0049] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0050] Figure 1 This is a schematic diagram illustrating a vehicle manufacturing tracking system according to some embodiments of the present disclosure, such as... Figure 1 As shown in the embodiments of this disclosure, the vehicle manufacturing tracking system may include a PLC and at least one processing device.

[0051] The PLC can be used to respond to the arrival of the target vehicle at the target location, obtain the vehicle identification on the vehicle body; determine the corresponding vehicle information based on the vehicle identification; and write the vehicle information into an RFID tag in the target vehicle, which is used to carry the target vehicle at the target location.

[0052] At least one processing device can be used to read RFID tags on a corresponding target vehicle to obtain corresponding vehicle information; determine the processing task to be performed based on the vehicle information; and execute the processing task, wherein the vehicle manufacturing process includes multiple steps, and at least one processing device is provided in any step.

[0053] It should be noted that a PLC can be a digital computing and operating electronic system designed for industrial applications. It uses a programmable memory to execute operational instructions such as logic operations, sequential control, timing, counting, and arithmetic operations, and controls various types of machinery or production processes through digital or analog input / output interfaces.

[0054] In some exemplary embodiments, vehicle identification can be pre-set on the target vehicle. For example, a PLC can receive a welding order online schedule from an upstream system, and then the PLC can generate a corresponding vehicle identification for the target vehicle. When the target vehicle arrives at the preset online position, the PLC can control a marking machine to engrave the vehicle identification on the target vehicle's body.

[0055] In an exemplary embodiment, the vehicle identification mark can be stamped onto the vehicle body as a steel stamp code. Alternatively, the vehicle identification mark can be applied to the vehicle body using methods such as thermal transcoding or electrochemical etching. Furthermore, this embodiment does not limit the location of the vehicle identification mark on the target vehicle; for example, the vehicle identification mark can be placed on the top of the target vehicle.

[0056] In an exemplary embodiment, the PLC can read the vehicle identification mark located on the body of the target vehicle using a camera, detector, or similar means. For example, taking a stamped code as the vehicle identification mark, the PLC can read the stamped code using a camera to obtain the vehicle identification mark.

[0057] It should be noted that this vehicle identifier can be used to uniquely identify the target vehicle; each vehicle has a different vehicle identifier. This vehicle identifier can be, for example, a VIN (Vehicle Identification Number). Therefore, after obtaining the target vehicle's vehicle identifier, the PLC can determine the target vehicle's model, the process to be performed, and the vehicle parameter information required for that process, etc., based on this identifier.

[0058] Then, the PLC can use at least one of the following as the vehicle information: the model of the target vehicle, the process to be performed, and the vehicle parameter information required for the process to be performed. It should be noted that this embodiment does not limit the specific content contained in the vehicle information, and the specific content contained in the vehicle information can be determined based on experience or application scenario.

[0059] In an exemplary embodiment, the PLC can acquire vehicle information at the target location and write the vehicle information into an RFID tag in the target vehicle, so that the vehicle information corresponding to the target vehicle carried by the target vehicle can be determined by reading the RFID tag in the target vehicle.

[0060] In some exemplary embodiments, the target location may include at least one of a vehicle change location and a production line start point, wherein, in response to the target location being a vehicle change location, the target vehicle is the changed vehicle.

[0061] It should be noted that since the vehicle manufacturing process may involve changing the vehicle, the vehicle information needs to be written to the new vehicle after the change. Additionally, the vehicle manufacturing process may involve multiple production lines. To ensure that each production line can perform the corresponding process based on the target vehicle, the vehicle information can be overwritten when the target vehicle arrives at the start point of the production line. This further improves the accuracy of vehicle tracking and identification, and avoids errors in vehicle manufacturing.

[0062] Furthermore, this disclosure does not limit the processes involved in vehicle manufacturing. For example, the processes may include at least one of welding, electrophoresis painting, topcoat painting, body assembly, final assembly, and quality inspection. Each process can be completed by at least one corresponding processing device. Any process may include at least one production line, and the processing device may be set on the corresponding production line.

[0063] In an exemplary embodiment, taking the welding process as an example, the carrier used in the welding process can be a welding sled. Therefore, when the target vehicle arrives at the welding floor assembly point, the target vehicle can be mounted on the welding sled. The PLC can obtain the vehicle identification by reading the stamped code on the vehicle body and determine the corresponding vehicle information based on the vehicle identification. Then, the PLC can write the vehicle information into the RFID tag on the welding sled. Subsequently, when the target vehicle enters any production line starting point in the welding process, the PLC can repeat the above operation to overwrite the vehicle information into the RFID tag on the welding sled.

[0064] For example, similarly, after the target vehicle completes the welding process, a coating electrophoresis process can be performed. The carrier used in the coating electrophoresis process can be a coating electrophoresis sled. After the target vehicle is switched from the welding sled to the coating electrophoresis sled, the PLC can obtain the vehicle identification by reading the stamped code on the vehicle body and determine the corresponding vehicle information based on the identification. Then, the PLC can write this vehicle information into an RFID tag on the coating electrophoresis sled. Furthermore, when the target vehicle enters any production line starting point in the coating electrophoresis process, the PLC can repeat the above operation to overwrite the vehicle information into the RFID tag on the coating sled.

[0065] For example, when a target vehicle enters the topcoat process, the vehicle used in the topcoat process can be a topcoat sled. After the target vehicle is transferred to the topcoat sled, the PLC can determine the corresponding vehicle information through the above operations. Then, the PLC can write the vehicle information into the RFID tag on the topcoat sled. Subsequently, when the target vehicle enters any production line start point in the topcoat process, the PLC can repeat the above operations to overwrite the vehicle information into the RFID tag on the topcoat sled.

[0066] In some exemplary embodiments, taking the welding process as an example, after the target vehicle enters the welding process, processing equipment can be installed in each production line of the welding process. This processing equipment can read the RFID tags on the welding sled to obtain vehicle information.

[0067] In an exemplary embodiment, an RFID reader may be installed on the processing equipment. The processing equipment can read the RFID tags on the corresponding vehicles to obtain the corresponding vehicle information. For example, the processing equipment located in the production line can be a process equipment capable of performing process operations. Therefore, after determining the vehicle information, the processing equipment can determine the processing task to be performed based on the vehicle information and execute it.

[0068] It should be noted that, due to the possibility of different vehicle models, placing RFID tags on the vehicle body would result in inconsistent RFID tag positions. This embodiment stores vehicle information in RFID tags on the vehicle, thus fixing the RFID tag position. This improves the reliability and accuracy of RFID tag identification, reduces the difficulty of setting up RFID readers on processing equipment, lowers the false reading rate, and reduces debugging difficulty. Furthermore, because this disclosure can reduce the reading distance of the RFID tags, high-frequency RFID can be used instead of ultra-high-frequency RFID, further reducing deployment costs. Secondly, since the target vehicle is used repeatedly, this disclosure avoids adjusting existing functions in mixed-line production situations, thus saving on modification costs.

[0069] In some exemplary embodiments, the vehicle manufacturing tracking system provided in this disclosure may further include a central control system.

[0070] The first processing device can be used to read the RFID tag on the target vehicle corresponding to the first process to obtain the vehicle information corresponding to the first processing device. The first process is any process in the vehicle manufacturing process, and the first processing device is any processing device in the first process. The first processing device can also be used to send the vehicle information corresponding to the first processing device to the PLC. The PLC can also be used to forward the vehicle information corresponding to the first processing device to the central control system. The central control system can be used to receive the vehicle information corresponding to the first processing device.

[0071] For example, the first process can be a welding process, an electrophoresis coating process, a topcoat process, etc. Taking the welding process as an example, the target carrier corresponding to the first process can be a welding sled, and the first processing equipment can be the processing equipment of any equipment in the production line of the welding process.

[0072] In an exemplary embodiment, after the first processing device reads the vehicle information, it can send the vehicle information corresponding to the first processing device to the PLC. The PLC can then send the vehicle information corresponding to the first processing device to the central control system. The central control system can store the vehicle information corresponding to the first processing device. Optionally, the central control system can also analyze the process operation status in the first process based on the vehicle information corresponding to the first processing device.

[0073] It should be noted that the embodiments of this disclosure can use the central control system to track and identify vehicles in each process of vehicle manufacturing, and can also use the central control system to analyze the process operation in each process, thus improving the reliability and accuracy of vehicle tracking and identification.

[0074] In some exemplary embodiments, the central control system is further configured to determine the processing task corresponding to the first processing device based on the vehicle information corresponding to the first processing device; and send the processing task corresponding to the first processing device to the first processing device.

[0075] In some exemplary embodiments, after the first processing device obtains vehicle information on the target vehicle corresponding to the first process, the first processing device determines whether it can determine a processing task to be executed based on the vehicle information. If it can, the first processing device determines the processing task to be executed based on the vehicle information. If it cannot, the first processing device can forward the vehicle information to the central control system via a PLC. The central control system then determines the processing task to be executed based on the vehicle information and returns the processing task to the first processing device via a PLC.

[0076] It should be noted that for simple operations, the embodiments of this disclosure can directly determine the processing task through the processing equipment, thereby improving vehicle manufacturing efficiency. However, for complex processes, a large number of relevant parameters may be required to determine the specific process operation. In this case, the processing task can be determined through the central control system, which can ensure the reliability and accuracy of the processing task during the vehicle manufacturing process.

[0077] In some exemplary embodiments, the vehicle manufacturing process corresponds to multiple regions, and each region corresponds to at least one process; wherein, the region includes a body scheduling region, and the processing equipment in the body scheduling region includes a second processing equipment; the central control system is further used to receive vehicle information corresponding to the second processing equipment; and to determine the vehicle assembly sequence based on the vehicle information corresponding to the second processing equipment.

[0078] In some embodiments, the various areas corresponding to the vehicle manufacturing process may include various workshops, body dispatching areas, quality inspection areas, etc. For example, the welding process can be deployed in the body workshop, the electrophoresis painting process and the topcoat painting process can be deployed in the painting workshop, the body dispatching process can be deployed in the body dispatching area, the final assembly process can be deployed in the final assembly workshop, and the quality inspection process can be deployed in the quality inspection area.

[0079] In an exemplary embodiment, for the vehicle dispatching area, the second processing device can be, for example, a conveying device such as a turntable or a high-speed stacker crane. Furthermore, this second processing device can be equipped with an RFID reader, thereby enabling the reading of RFID tags on the corresponding target vehicle to obtain vehicle information corresponding to the second processing device.

[0080] In one possible implementation, after the target vehicle completes the electrophoretic topcoat process, the carrier can be changed from the topcoat sled to the final assembly sled. The PLC can read the vehicle identification markings on the target vehicle's body via a camera and write the corresponding vehicle information into an RFID tag in the final assembly sled. Then, the target vehicle can be transported using a second processing device. Therefore, the second processing device can read the RFID tag in the final assembly sled to obtain the vehicle information corresponding to the second processing device.

[0081] For example, the second processing device can send the vehicle information corresponding to the second processing device to the PLC, and then forward it to the central control system via the PLC. The central control system can schedule the entry and exit of target vehicles based on the vehicle information corresponding to the second processing device. In addition to the vehicle information corresponding to the second processing device, the central control system can also schedule the entry and exit of target vehicles based on at least one of the following: entry and exit cycle time information, final assembly process constraint information, and material leveling information, in order to determine the vehicle assembly sequence.

[0082] In some exemplary embodiments, the vehicle body scheduling area may contain multiple vehicles awaiting final assembly. The central control system can uniformly schedule these multiple vehicles to determine their order of entry into the final assembly process, i.e., the vehicle assembly sequence. For example, the vehicle body scheduling area may include an assembly sequence point. The target vehicle can arrive at this assembly sequence point after the vehicle assembly sequence has been determined. In response to the target vehicle arriving at the assembly sequence point, the PLC can obtain a vehicle identification mark from the target vehicle to determine vehicle information, and then overwrite this vehicle information onto an RFID tag in the final assembly sled.

[0083] It should be noted that, in this embodiment of the present disclosure, the vehicle assembly sequence is determined by the central control system based on the vehicle information corresponding to the second processing device. This facilitates the tracking of the target vehicle in subsequent assembly processes, thereby further improving the accuracy and reliability of vehicle manufacturing tracking.

[0084] In some exemplary embodiments, the area further includes a final assembly area, and the processing equipment in the final assembly area includes a third processing equipment. The third processing equipment is further configured to send a workstation arrival signal to the central control system; the central control system is further configured to determine the target workstation where the target vehicle is located based on the workstation arrival signal and the vehicle assembly sequence; determine the processing task corresponding to the target workstation based on the vehicle information corresponding to the third processing equipment; and send the processing task corresponding to the target workstation to the processing equipment at the target workstation.

[0085] In some possible implementations, when the target vehicle enters the final assembly process, it may pass through the pre-interior trim line and the interior trim line sequentially. When the target vehicle switches from the pre-interior trim line to the interior trim line, the carrier needs to be changed. For example, the carrier can be changed from the final assembly skid to the final assembly plate. The PLC can read the vehicle identification on the target vehicle body through a camera and write the corresponding vehicle information into the RFID tag in the final assembly plate.

[0086] It should be noted that the PLC can also read the RFID tags in the final assembly sled to obtain vehicle information and write the vehicle information into the RFID tag in the final assembly plate. This disclosure does not limit this. In addition, the vehicles involved in the final assembly process may also include lifting equipment, which may be equipped with corresponding RFID tags. This disclosure does not limit the type of vehicle.

[0087] In an exemplary embodiment, after replacing the final assembly plate, the target vehicle can be transported using a third processing device. Exemplarily, for the final assembly area, the third processing device can be, for example, a conveying device. The final assembly area may include multiple workstations, each equipped with a corresponding processing device. Vehicles can enter each workstation according to their final assembly sequence. For example, the vehicles include vehicle 1, vehicle 2, and vehicle 3, and the workstations include workstation 1, workstation 2, and workstation 3. According to the final assembly sequence, vehicle 1 first enters workstation 1 for the corresponding process operation. Then, vehicle 1 can enter workstation 2, and vehicle 2 can enter workstation 1 according to its final assembly sequence. Then, vehicle 1 can enter workstation 3, vehicle 2 can enter workstation 2 according to its final assembly sequence, and vehicle 3 can enter workstation 1.

[0088] For example, when a vehicle is detected arriving at a certain workstation, the third processing device can generate a corresponding workstation arrival signal and send the workstation arrival signal and vehicle information to the central control system. At this time, the central control system can determine the target workstation where the target vehicle is located based on the workstation arrival signal and the vehicle assembly sequence through an algorithm, thereby determining the processing task corresponding to the target workstation.

[0089] It should be noted that, taking vehicles 1, 2, and 3 as examples, when vehicle 1 enters workstation 2 and vehicle 2 enters workstation 1, the central control system can receive the workstation arrival signals corresponding to workstations 1 and 2, as well as the vehicle information corresponding to vehicles 1 and 2, respectively. Then, the central control system can use algorithms to deduce that vehicle 1 corresponds to workstation 2 and vehicle 2 corresponds to workstation 1. Based on the corresponding vehicle information, it determines the processing tasks corresponding to workstation 2 and workstation 1, respectively, and sends these tasks to the processing equipment at the corresponding workstations, thereby realizing the process operations for vehicles 1 and 2.

[0090] It should be noted that, in this embodiment of the disclosure, the central control system determines the processing tasks corresponding to each workstation based on the vehicle information corresponding to the third processing device and the workstation arrival signal. This facilitates the collaborative management of each workstation and the tracking of the manufacturing process of each vehicle, further improving the efficiency of vehicle manufacturing tracking and ensuring accuracy and reliability.

[0091] In some exemplary embodiments, the vehicle manufacturing tracking system provided in this disclosure may further include: an on-board device, configured to determine the location information of a target vehicle in response to power-on of the on-board device; and send the location information to a central control system.

[0092] In an exemplary embodiment, the in-vehicle device can be a vehicle infotainment system, a T-Box (Telematics-Box), or a vehicle-to-everything (V2X) box. Once the in-vehicle device is installed, tested, and powered on, it can communicate with the TSP (Telematics Service Provider) system to obtain the vehicle's location information. For example, this location information may include the latitude and longitude coordinates of the target vehicle.

[0093] For example, the central control system can draw and store the latitude and longitude coordinate ranges of various regions and include a TSP vehicle positioning interface. The input parameters of this TSP vehicle positioning interface can include the vehicle identifier, and the output parameters can include the vehicle's location information. Additionally, the output parameters can also include the vehicle's driving trajectory. Taking the vehicle identifier as a VIN as an example, the central control system can obtain the target vehicle's location information based on the T-Box by calling the TSP vehicle positioning interface in real time and inputting the target vehicle's VIN. It can then perform corresponding location mapping based on the maps of various regions.

[0094] It should be noted that the embodiments of this disclosure achieve the positioning of the target vehicle through the vehicle-mounted equipment, which can realize vehicle manufacturing tracking in the quality inspection area and the vehicle waiting area after the final assembly process is completed, thereby realizing the full-process tracking and identification of the vehicle manufacturing process.

[0095] The vehicle manufacturing tracking system provided in this disclosure can acquire vehicle identification information from the vehicle body and write the corresponding vehicle information into an RFID tag in the target vehicle. This enables vehicle tracking and identification by reading the RFID tag in the target vehicle.
