[0031] The present application is described below with reference to the flow chart explanation, block diagram and / or flow chart according to the method and system of the embodiment of the present application.It will be understood that each frame of these flow chart explanations and / or block diagrams and the combination of flow chart explanations and / or block diagrams can be realized by computer program instructions.These computer program instructions can be provided to the processor of general-purpose computer, special-purpose computer or other programmable data processing equipment to form a machine, so that these instructions performed by the processor of computer or other programmable data processing equipment create the parts for implementing the function / operation specified in these flow charts and / or frame and / or one or more flow charts.It should also be noted that in some alternative implementations, the function / operation shown in the frame may not occur in the order shown in the flow chart.For example, two frames shown successively can actually be performed substantially simultaneously or these frames can sometimes be performed in reverse order, specifically depending on the function / operation involved.

[0032] These computer program instructions can be loaded onto a computer or other programmable data processor so that a series of operating steps are performed on the computer or other programmable processor to form a computer-implemented process so that these instructions performed on the computer or other programmable data processor provide steps for implementing the functions or operations specified in one or more frames of this flow chart and / or block diagram.

For example, the two frames shown in sequence can actually be performed substantially simultaneously or these frames can sometimes be performed in reverse order, depending on the functions / operations involved.

[0033] Hereinafter, various exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Figure 1As shown, Figure 1 FIG. 1 is a schematic block diagram of a control system 10 for the entire life cycle of a prototype trial production according to an embodiment of the present application. Figure 1 As shown, the system 10 includes a plan management submodule 101 , a process management submodule 102 , a site management submodule 103 , a quality management submodule 104 , and a prototype status submodule 105 .

[0034] The planning management submodule 101 can be used to obtain prototype order information, merge machine batches by identifying the prototype delivery date, and generate a trial production plan and a bill of materials based on the order information. Optionally, the planning management submodule 101 can generate trial production capacity and trial production report information based on the trial production plan.

[0035] The process management submodule 102 can be used to generate a section flow data table based on the trial production plan generated by the plan management submodule 101, and update the section flow data table based on an update instruction.

[0036] Since parts changes are very frequent during the trial production phase of automotive drive system products, the control system described in the present application can continue to track one or more approval instructions associated with the update instruction after receiving an update instruction (e.g., a change request entered by the requester on the computer side). For example, after receiving the first approval instruction (e.g., from the first person in charge) and the second approval instruction (e.g., from the second person in charge), the process management submodule 102 can update the section flow data table in response to the first approval instruction and the second approval instruction, and synchronize the updated section flow data table to the on-site computer side. The on-site operator can continue the operation only after confirming that it has been read, to ensure that the change measures are implemented. In addition, the change file can be bound to the corresponding template database of the prototype, realizing a full record of the trial production process and improving traceability.

[0037] The on-site management submodule 103 may be used to obtain quality problem information through an external device and generate a dimming light activation signal based on the problem information. Optionally, the external device includes a mobile terminal and / or a scanning device. Exemplarily, the on-site management submodule 103 may be communicatively coupled to the external device in a wired or wireless manner. Alternatively, the on-site management submodule 103 may also obtain quality problem information by receiving input instructions from on-site staff.

[0038] Optionally, the site management submodule 103 may also present the trial production plan, and obtain parts assembly information and trial production product information through an external device.

[0039] Optionally, the site management submodule 103 may also present a corresponding prefabricated prototype template and customization requirements for the template based on the acquired parts assembly information and trial product information.

[0040] The quality management submodule 104 can be used to present quality problem information to a specific object based on the identification of the quality problem information type. Optionally, the quality management submodule 104 can also receive feedback information for the quality problem information and generate a dimming light off signal based on the feedback information. Optionally, the quality management submodule 104 can be used for problem response and tracking, linked with the on-site virtual dimming light system, and equipped with a problem report function.

[0041] The prototype state submodule 105 can be used to receive a dark light activation signal and update the trial production plan based on the dark light activation signal. Optionally, the prototype state submodule 105 can also display machine station state information, machine progress information, and generate key time node information based on the work section flow data table.

[0042] According to the present application, each submodule of the control system 10 used for the entire life cycle of prototype trial production can communicate information through a local area network, and can also obtain parts assembly information, trial product information and quality problem information through external devices (for example, scanners, tablet computers, barcode printers, etc.).

[0043] Continue to refer Figure 2 , Figure 2 A schematic diagram of a release process implemented by a plan management submodule according to an embodiment of the present application is shown.

[0044] In step S201, first, the planning management submodule may receive trial production plan data (for example, from a project startup engineer), and automatically synchronize the machine manufacturing data with a status of "merged machine manufacturing batches" in the upstream system to the planning management submodule, thereby ensuring that all information has "one source and one origin".

[0045] In step S202, the trial production capacity information set according to the production schedule is received, and the trial production capacity configuration information and the configurable total amount information are received, so that the on-site resources are maximized and there is no queuing.

[0046] In step S203, the maintenance information of the section flow schedule is received. The maintenance information can be input in batches or in a single entry, and the original upstream information cannot be modified to ensure the consistency of the data.

[0047] In step S204, a trial production plan is generated and released. The system will automatically verify the capacity configuration, locking information, and required input before release. If the verification passes, a release instruction is generated and sent to the system associated with the project, and the bill of materials (BOM) is released and materials are pulled, thereby ensuring information consistency and improving communication quality and efficiency.

[0048] Continue to refer Figure 3A and Figure 3B , Figure 3A and Figure 3B Schematic diagrams of template data (Build Book) publishing and on-site entry processes according to an embodiment of the present application are respectively shown.

[0049] like Figure 3A As shown, for the Build Book release process, in order to balance the requirements of unified management and free configuration, the template data can be divided into primary template data and secondary template data. For example, the primary template data can be used to establish a template library for all project trial production information records and tests, thereby facilitating unified management. For example, the secondary template data can filter out the records and test items required for a project from the template library of the primary template data for a specific model, thereby achieving the purpose of flexible and free configuration. Optionally, the template configuration supports illustrations, formula calculations, automatic SPEC verification, and preview functions. As shown Figure 3A The template data publishing process shown has a complete version management function. The template data of each prototype model will only correspond to one template, and after the new official version is released, the old version will be automatically deactivated, thereby ensuring the consistency of data records.

[0050] like Figure 3B As shown, for the Build Book entry process, the entry terminal uses a tablet computer for entry. When the on-site operator scans the QR code of the whole machine, the system will automatically match the corresponding template data template according to the RPO number of the prototype, and display the basic information, BSD (if any) and customization requirements (if any) of the prototype. For example, the on-site management submodule can present the corresponding prefabricated prototype template and the customization requirements for the template based on the collected parts assembly information and trial product information. After confirming and checking, the on-site operator can assemble and record the trial information. The advantage of using electronic entry in the entry process is that the system can display data deviation items in a timely manner, automatically generate reminders for feedback issues, and enter the issue management process. Optionally, the on-site management submodule can be linked with the virtual dark light system to realize on-site intelligent management and improve the quality of prototype trial production. Optionally, the system can only enter the review process when it detects that all template data has been entered completely. Optionally, the template data filling status can be viewed in real time remotely to facilitate engineers to conduct remote monitoring and problem handling, greatly improving the response speed.

[0051] Figure 4 A logical schematic diagram of an intelligent process flow configuration according to an embodiment of the present application is shown.

[0052] like Figure 4As shown, the process management submodule can generate a background data table based on all the types of process flows that the prototype needs to go through from assembly to final inspection and offline completion. By identifying the relevant information in the process flow schedule, the process flow that the prototype needs to complete can be obtained. Optionally, when the previous process in the process flow is completed, the process management submodule can generate prompt information and push it to the person in charge of the next process flow, thereby realizing the intelligent flow of prototypes and reducing the probability of errors and communication costs. Optionally, the background data table can be edited and configured. When a new process flow appears due to process adjustment, only the background data table needs to be adjusted to adapt to the new process flow.

[0053] Figure 5A A schematic diagram of an on-site whole-machine scanning process according to an embodiment of the present application is shown.

[0054] like Figure 5A As shown in the figure, when the trial production plan is delivered to the site, the team leader can arrange the workstations in the site management submodule. When 100% of the materials arrive at the transfer area, the team leader can directly click the "delivery" button to notify the warehouse to deliver the whole machine materials to the first workstation; when the materials arrive at the site, the team leader can choose to print the whole machine QR code, which contains the basic information of the prototype and can be recognized by the upstream and downstream systems. It will follow the whole life cycle of the prototype to achieve unified management. Each workstation will be equipped with a handheld scanner. After the operator successfully scans the whole machine QR code (logic: the machine manufacturing station and the team leader are arranged in the same way + the station is not occupied + the whole machine scanning of the front machine manufacturing station is completed), it means that the prototype enters the station; if there are any problems during the trial production / testing process, the operator can directly feedback the problem through the scanner, support the selection of problem type and basic description, support taking pictures and illustrations, enter the issue management process, and link with the virtual dark light system to realize on-site intelligent management and improve the quality of prototype trial production. When the work section is completed, the operator can click the Done button, and the system will verify whether all issues have been resolved (for assembly stations, the BOM assembly status must also be verified). If the verification passes, the system can generate a prompt message and send it to the relevant person in charge of the next station, realizing the intelligent station flow function.

[0055] Figure 5B A schematic diagram of an on-site material scanning process according to an embodiment of the present application is shown.

[0056] like Figure 5BAs shown, first, the system can obtain the assembly material BOM of the station according to the corresponding relationship between the station and the material station in the bill of materials (BOM), that is, split the entire prototype BOM into different sub-BOMs according to different stations, and realize the intelligent verification BOM function. When the material is shipped out, each part will be accompanied by a QR code label. The assembly station technician can use a handheld scanner to scan the assembly material part label. If the scanned part is not in the assembly BOM, the system automatically prompts to confirm whether to assemble it. If the assembly is confirmed, the issue management process will be entered. The process engineer must be approved before the assembly can continue to improve the quality of the trial production; when clicking "Finish", the system automatically verifies the actual assembly BOM and the assembly BOM of this station, checks for wrong installation and missing installation, and automatically prompts to feedback the issue if there is a problem, and enters the issue process. In addition, the actual assembly BOM formed by scanning will be bound to the template data of the prototype, so that the detailed parts assembly time, assembly station, and the actual situation of parts assembly (assembled, not assembled, exceeding BOM) can be viewed to achieve accurate traceability of parts assembly; and the scanned data will be transmitted back to the system in real time, and the status dashboard of the prototype status submodule will display the completion percentage of the prototype trial production to achieve real-time monitoring.

[0057] Figure 6 A schematic diagram of an issue management process according to an embodiment of the present application is shown.

[0058] like Figure 6 As shown, first of all, there are two ways to generate issues. One is the scanner and tablet terminal mentioned above, and the other is the active input of the quality engineer's computer. Once an issue is generated, it will be linked to the virtual dark light system, the status light will turn red, and the site cannot continue to operate, realizing intelligent management. Next, the system will identify the project corresponding to the issue, and then push it to the process engineer of the project. The process engineer will make a preliminary judgment on the issue to determine whether it can be released first. If it is confirmed that there are other problems other than the first 3 diamonds, it cannot be released. You can add notes to the issue and submit it to the corresponding quality engineer. If it is confirmed that it is not a problem or a first 3 diamond problem, it can be released first. After releasing and filling in the on-site measures, it will be linked to the virtual dark light system, the status light will turn green, and the site can continue to operate, and the system will save the release record. If the issue is transferred to the quality engineer, you can enter the issue resolution link. First, according to the part number information and issue description, it will be assigned to a specific person in charge. The person in charge needs to fill in the root cause analysis, short-term solution measures, short-term measure breakpoints, long-term solution measures, and long-term measure breakpoints. The quality engineer needs to confirm the long and short-term measures before closing the issue. In addition, the entire issue flow process will be recorded by the system to facilitate problem tracing.

[0059] Figure 7FIG. 4 shows a schematic block diagram of a prototype state submodule 70 according to an embodiment of the present application.

[0060] like Figure 7 As shown, the prototype status submodule 70 includes a virtual dimming system 701 , a status dashboard 702 , an on-site dashboard 703 , and a progress dashboard 704 .

[0061] The virtual dark light system 701 can be linked with issue management. The status lights are red and green. When there is no issue, the light is green and the operation can proceed normally. When the issue triggers the red light, further assembly or test operations will be restricted until on-site solutions are given. This allows for intelligent on-site management and improved trial production quality.

[0062] The status dashboard 702 can display the status of the prototype being trial-produced on site, such as the red and green light status, the machine manufacturing station, and the machine manufacturing progress (percentage), so as to realize remote and intuitive display of the real-time status of the prototype and improve communication efficiency.

[0063] The on-site dashboard 703 can display the working status of each workstation from the perspective of the on-site workstation, such as idle, locked, prototype queue status, etc., so as to intuitively display the on-site workstation status and facilitate the team leader to manage the trial production plan;

[0064] The progress dashboard 704 can display all key time node information of the prototype from the submission of the need to the delivery, and record the entire life cycle of the prototype from the time dimension.

[0065] The foregoing disclosure is not intended to limit the disclosure to the precise form disclosed or to the particular field of use. Therefore, it is contemplated that various alternative embodiments and / or modifications of the disclosure are possible in light of the present disclosure, whether explicitly described or implied herein.
