This embodiment is applicable to the situation of monitoring the production process of vehicles. This method can be executed by a vehicle production management device, which can be implemented in the form of hardware and / or software, and can be configured in any electronic device with network communication functions. As Figure 1 shown, this method includes:

[0028] S110. Determine reference change information.

[0029] Among them, the reference change information is used to characterize the change information corresponding to the nodes where the production conditions of the target vehicle change during the production process.

[0030] Exemplarily, the reference change information can be: operator A is replaced by operator B, production equipment C has wear, and production part D has quality problems, etc.

[0031] Among them, the nodes are each process point for assembling and fitting the target vehicle.

[0032] Exemplarily, the nodes can be: operators, production equipment, production parts, operation methods, and operation environments, etc.

[0033] Specifically, retrieve the reference change information corresponding to the target vehicle from the vehicle management system.

[0034] Among them, the vehicle management system is used to store the information of each process node of vehicle production.

[0035] Exemplarily, as Figure 2 shown, the vehicle management system includes: a manufacturing operation platform, a construction management system, a personnel attendance system, and a production management and material system, etc.

[0036] Among them, the manufacturing operation platform is used to provide the operation methods for vehicle production; the construction management system is used to provide information on the wear and repair of production equipment, etc.; the personnel attendance system is used to provide information on the changes of operators and the proficiency of operators in operating production equipment; the production management and material system is used to provide the types, specifications, and quality of production parts.

[0037] S120. Screen the reference change information according to the preset production requirements to obtain the target change information.

[0038] Among them, the preset production requirements are used to characterize the requirement information of each production node to ensure that the target vehicle meets the production requirements.

[0039] Exemplarily, the preset production requirements can include: the training for operators to complete the operation of production equipment needs to reach level 1, and production parts adopt S-level parts, etc.

[0040] Among them, the target change information is the information corresponding to the nodes that affect the production quality of the target vehicle.

[0041] Exemplarily, the target change information can be that the panel welding at the water leakage part is not solid, the type change of the spot welding machine at the ▽S part, etc.

[0042] Specifically, the reference change information is screened according to the requirement information of each production process point included in the preset production requirements, and the reference transformation information that can affect the quality of the target vehicle is used as the target change information.

[0043] Exemplarily, as Figure 3 shown, the change point information, that is, the reference change information, is obtained from the manufacturing operation platform, the construction management system, the personnel attendance system, the production management and material system, etc. According to the preset production requirements, the information of the operators, production equipment, production parts, operation methods, and operation environment that affect the quality of the target vehicle is screened from the reference change information as the target change information.

[0044] S130. Determine the quality information of the target vehicle according to the associated features and the target change information.

[0045] Among them, the associated features are used to characterize the changes brought about by the combination of different target change points.

[0046] Exemplarily, as shown in Table 1, the quality changes caused by the changes in the models of the PVC coater, the sealant coater, the painting robot, the drying furnace and the use of unskilled operators at the heavy product station are the PVC adhesion and color combination defects at the ▽S fastening part.

[0047] Among them, the target change point is the node corresponding to the target change information.

[0048] Exemplarily, as shown in Table 1, the target change points can be: PVC coater, sealant coater, painting robot, drying furnace, and operators at the heavy product station, etc.

[0049] Table 1 Association Feature Table

[0050]

[0051] Among them, the heavy product station is a workbench used for heavy work in the production of the target vehicle.

[0052] Specifically, the target change information is classified according to the deployment situation of each link in the production of the target vehicle, and the classified target change information is compared with the associated features. If they are consistent, it is considered that there is a problem with the quality of the target vehicle, and the target vehicle represents a non-conforming product of the target vehicle.

[0053] Exemplarily, assume that the target change information of the vehicle body only includes the change of the spot welder at the ▽S position, and this change alone will not cause the target vehicle to leak water. Therefore, the production of the vehicle body part of the target vehicle is qualified.

[0054] Exemplarily, assume that the target change information of the vehicle body includes: the change of the windshield gluing machine, the change of the ■×× production instruction, and the non-standard operation of the operator at the rework station. This indicates that the production of the target vehicle at the assembly section is unqualified.

[0055] Optionally, determining the reference change information includes steps A1 - A3:

[0056] Step A1: Obtain the production information corresponding to each node on the vehicle production line.

[0057] Specifically, obtain the production information corresponding to each node on the vehicle production line from the vehicle management system.

[0058] Step A2: Match the corresponding production information from the production information according to the identification information of the target vehicle to obtain the reference production information.

[0059] Among them, the identification information uniquely represents the target vehicle.

[0060] Specifically, match the production information corresponding to the identification information from the obtained production information as the reference production information.

[0061] Step A3: Perform change screening on the reference production information to obtain the reference change information.

[0062] Specifically, traverse the data in the reference production information, and extract the changed information in the reference production information to obtain the reference change information.

[0063] Optionally, the determination process of the associated features includes steps B1 - B4:

[0064] Step B1: Determine the target vehicle evaluation information.

[0065] Among them, the target vehicle evaluation information is used to represent the information of production problems that affect the safety performance and driving performance of the target vehicle.

[0066] Among them, the production problem is the quality problem of the target vehicle caused by the comprehensive effect of multiple target change points.

[0067] Specifically, obtain the feedback information and fault repair information of the vehicles that have left the factory from the vehicle management system, and classify and organize the obtained feedback information and fault repair information to obtain the target vehicle evaluation information.

[0068] Step B2. Screen the historical change information according to the target vehicle evaluation information to obtain the comprehensive change information.

[0069] Specifically, obtain the historical change information of vehicle production from the vehicle management system, and screen the historical change information according to the target vehicle evaluation information to obtain the comprehensive change information.

[0070] Step B3. Classify the comprehensive change information according to the production deployment of the target vehicle to obtain the reference classified change point information.

[0071] Among them, the production deployment of the target vehicle is the deployment situation of the target vehicle production line, that is, the body department, the painting section, the molding section, and the assembly section.

[0072] Exemplarily, classify and screen the comprehensive change information according to the production deployment situation of the target vehicle, and put those belonging to the same production deployment together to obtain the reference classified change point information.

[0073] Step B4. Determine the associated features according to the influence degree of the reference classified change point information on the target vehicle.

[0074] Specifically, determine the associated features according to the influence degree of the reference classified change points on the target vehicle and the influence degree of the combination of the reference classified change points on the target vehicle.

[0075] Exemplarily, assume that the only change point in the body department is the change of the spot welder at the ▽S position, but the change of the spot welder at the ▽S position is not sufficient to affect the quality of the vehicle, then the associated feature is that the change of the spot welder at the ▽S position is qualified for production; assume that the change points in the body department are the change of the spot welder at the ▽S position, the M jig, and the panel welding at the water leakage position, then the combination of the three will cause water leakage and vehicle specification problems in the vehicle, so the associated feature is that the spot welder at the ▽S position, the M jig, and the panel welding at the water leakage position will cause water leakage and vehicle specification problems in the vehicle.

[0076] Optionally, determining the associated features according to the influence degree of the reference classified change point information on the target vehicle includes steps C1 - C2:

[0077] Step C1. Perform fault association on the reference classified change point information to obtain the fault change information.

[0078] Specifically, perform fault association on the reference classified change information, that is, associate the change information that can cause vehicle quality and fault problems when combined with each other in the reference classified change information.

[0079] Exemplarily, assume that the obtained reference classification change information of the vehicle body part is as follows: the spot welder at the ▽S part changes from type H to type J or the spot welder at the ▽S part changes from type H to type L. However, only the combination of the change of the spot welder at the ▽S part from type H to type J and the changes that occur in the welding of the M jig and the water leakage part plate can cause quality problems of the vehicle. Then, the change of the spot welder at the ▽S part from type H to type J can be used as the fault change information.

[0080] Step C2: Determine the associated features according to the impact degree of the fault change information on the quality of the target vehicle.

[0081] Specifically, evaluate the impact degree of the obtained fault change information on the vehicle, and construct associated features based on the impact degree of the combination of the fault change information on the quality of the target vehicle.

[0082] Optionally, according to the associated features and the target change information, determine the quality information of the target vehicle, including steps D1 - D3:

[0083] Step D1: Classify the target change information according to the production deployment of the target vehicle to obtain the classified change point information.

[0084] Specifically, classify the target change information according to the process nodes required by the production processes of the vehicle body part, the painting section, the molding section, and the assembly section to obtain the classified change point information.

[0085] Step D2: Evaluate the target vehicle according to the associated features and the classified change point information to obtain the evaluation information.

[0086] Specifically, conduct a quality evaluation on the target vehicle according to the classified change point information to obtain the first evaluation information; combine and evaluate the classified change point information according to the associated features to obtain the second evaluation information, and combine the first evaluation information and the second evaluation information to obtain the evaluation information.

[0087] Step D3: Determine the quality information of the target vehicle according to the evaluation information.

[0088] Determine whether there are quality problems with the target vehicle according to the evaluation information. If so, the quality information of the target vehicle indicates that the target vehicle is unqualified, and record the unqualified content; if not, the quality information of the target vehicle indicates that the target vehicle is qualified.

[0089] Exemplarily, assume that the evaluation information is that the color combination of the target vehicle is unqualified and there is PVC adhesion at the ▽S fastening part, then it indicates that the target vehicle has quality problems.

[0090] Optionally, after determining the quality information of the target vehicle according to the associated features and the target change information, it further includes steps E1 - E2:

[0091] Step E1: If the quality information of the target vehicle indicates that the target vehicle is qualified, a certificate of conformity is generated.

[0092] Among them, the certificate of conformity is configured with the qualification information of the target vehicle and an electronic change voucher.

[0093] Among them, the electronic change voucher is composed of production change information and can only be obtained by the vehicle manufacturer or the repair party.

[0094] Specifically, if the quality information of the target vehicle indicates that the target vehicle is qualified, the obtained target change information and qualification information are used to generate a certificate of conformity.

[0095] Step E2: If the quality information of the target vehicle indicates that the target vehicle is unqualified, the target vehicle is repaired according to the target change information corresponding to the unqualified part.

[0096] Specifically, if the quality information of the target vehicle indicates that the target vehicle is unqualified, the target change information of the unqualified part is obtained, the repair method is determined according to the target change information, and the target vehicle is repaired. After the repair is completed, a vehicle quality inspection is carried out. If the inspection is successful, a certificate of conformity is generated; if the inspection is unsuccessful, the repair continues until it is qualified.

[0097] Exemplarily, as Figure 3 shown, the manufacturing department obtains the change point evaluation information, that is, the quality information of the target vehicle, and judges whether the case IP device is closed according to the leading information of the change point evaluation information. If not, a reminder is given. If so, the target vehicle is evaluated according to the quality information of the target vehicle. If the target vehicle is qualified, it indicates that the target vehicle can be shipped; if the target vehicle is unqualified, it is entered into the on-site inspection information system, and the target vehicle is repaired according to the target change information. If the repair is qualified, a certificate of conformity is printed through the certificate of conformity printing system; if the repair fails, the repair continues. If the quality information of the target vehicle cannot determine whether it is qualified, it enters the subsequent process for further evaluation; if the quality information of the target vehicle cannot judge the quality problems caused by the heavy product work station node, the target change information corresponding to the heavy product work station node is directly sent to the inspection section for further evaluation.

[0098] The technical solution of this embodiment determines the reference change information; screens the reference change information according to the preset production requirements to obtain the target change information, which can effectively screen out the change information that affects the quality of the vehicle and provide a basis for the subsequent evaluation of the vehicle quality; determines the quality information of the target vehicle according to the associated features and the target change information. This method can observe the changes at each process point in the vehicle production process in real time, evaluate the quality of the vehicle according to the changes, and can prevent the production and shipment of unqualified vehicles.
