TECHNICAL FIELD

[0001] The present application relates to the technical field of production execution, and in particular to a method and system for automatically starting a process based on multi-modal scanning. BACKGROUND

[0002] Batch production often requires multiple processes for a single instruction, and each process is composed of multiple different sub-processes, including material feeding sub-activities and a series of production activities. When the process and sub-process are complex, each process needs to be started, then the sub-process list is entered, and then the sub-process is started, which greatly increases the operation cost of the front-line operators, thereby affecting the production efficiency of the entire factory.

[0003] The prior art has the disadvantage that the scanning is single, and there is no adaptation to factory-level scanning, and it cannot be applied to the specific production execution process, and there is a lack of a method for automatically executing a process through scanning. For example, the Chinese patent with the publication number CN110175025A can configure a production process flow, but cannot solve the above-mentioned defects. SUMMARY

[0004] The present application solves the problem of the lack of a method for automatically executing a process through scanning in the prior art, and proposes a method and system for automatically starting a process based on multi-modal scanning, which can automatically start a process, greatly reducing the operation cost of the front-line operators and improving the production efficiency of the factory.

[0005] In order to achieve the above-mentioned purpose, the following technical solution is adopted: a method for automatically starting a process based on multi-modal scanning, comprising the following steps: S1, selecting a scanning mode to scan, and the PDA end analyzes the scanned information after obtaining the scanned information; S2, determining whether the analysis is successful, if so, assembling data to initiate a request to the background server, if not, re-scanning; S3, the background server queries the corresponding process according to the reference, and sets the process to an open state; S4, the PDA end automatically queries the corresponding sub-process under the above-mentioned process, and sets the first sub-process state to an open state.

[0006] The present application integrates multiple scanning modes and applies them to the production execution process, which not only simplifies the operation of the operators, but also improves the production efficiency of the factory; from single scanning to multi-modal adaptation, from static management to dynamic execution; from manual step-by-step operation to full-automatic chain triggering; through pilot data verification, the production efficiency is improved by 35%, and the error rate is reduced by 90%.

[0007] The present application further provides that the step S1 comprises: S11, start the ScanService of the PDA end, and then the operator dynamically selects a scanning mode according to a scene; S12, perform an initialization operation according to the selected scanning mode, and then determine whether the initialization is successful, if yes, perform a scanning operation, and then analyze the data obtained by scanning; if no, reselect a scanning mode.

[0008] In the technical solution, after a specific scanning mode is selected, an initialization operation is performed according to the scanning mode, if the initialization operation is successfully completed, scanning is performed, and if the initialization is not successful, a scanning mode needs to be reselected for scanning.

[0009] The application further provides that the step S2 comprises: After the analysis is successful, the analyzed data is returned to the ScanService, the ScanService responds to the callback after scanning, and initiates a request for starting a process to a background server.

[0010] In the technical solution, the analysis and callback process are implemented in a scanning SDK, and the scanning server responds to the callback data and initiates a corresponding request.

[0011] The application further provides that the step S3 comprises: S31, the background server receives a request, and searches for a process that has not been started according to an instruction sheet ID passed. S32, the processes that have not been started are traversed until a corresponding process that has not been started is found, and the process is started; if the corresponding process that has not been started is not found, scanning is reperformed.

[0012] In the technical solution, the scanning server can respond to the callback data and send a request to the background server, and the background server can perform process traversal according to the received instruction sheet ID.

[0013] The application further provides that the step S3 further comprises: If the process is successfully started, the SDK is returned, scanning is ended, and resources are released; if the process is not successfully started, a corresponding prompt is sent, and the scanning interface is returned.

[0014] The application further provides that the step S4 comprises: S41, the client updates a process state, and enters a sub-process page. S42, it is determined whether there is a sub-process in the sub-process page, if yes, the sub-process list order is executed, and if no, a prompt is sent. S43, it is determined whether the sub-process is successfully started, if yes, the process is ended.

[0015] The process can be performed in the client.

[0016] The application further provides that, in step S43, if the sub-process fails to start, the sub-process list is manually refreshed to trigger the automatic starting of the sub-process function.

[0017] In the technical solution, the automatic starting of the sub-process function can be triggered after the sub-process fails to start.

[0018] The application further provides that the process status and the sub-process status can be updated to the client and the background server in real time.

[0019] In the technical solution, real-time status synchronization and dynamic resource allocation can be achieved, wherein the real-time status synchronization refers to the real-time updating of the process status and the sub-process status to the client and the server, and the dynamic resource allocation refers to the automatic release of the related device resources after the process is started.

[0020] The application further provides that the scanning modes include visual recognition, infrared, NFC and ultra-high frequency RFID, and the visual recognition specifically adopts an integrated camera.

[0026] Figure 2 is a detailed flowchart of a method for automatically starting a process based on multi-modal scanning according to the present application. DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present application clearer, further detailed descriptions will be given below in conjunction with the accompanying drawings and examples. It should be understood that the specific implementation described herein is only one of the best modes of the present application, which is used to explain the present application and does not limit the protection scope of the present application. All other examples obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0028] In batch production, one instruction sheet often needs to be composed of multiple processes, and one process is composed of multiple different sub-processes. When the processes and sub-processes are relatively complex, each process needs to be clicked to start, and then enter the sub-process list, and then start the sub-process. This obviously greatly increases the operation cost of the front-line operators, and further affects the production efficiency of the entire factory.

[0029] The prior art has the disadvantage that the scanning is single, and no adaptation is made for factory-level scanning, and it cannot be applied to specific production execution processes, and lacks a method for automatically executing a process or a sub-process through scanning.

[0030] Example 1 In view of the deficiencies of the prior art, the present embodiment proposes a method for automatically starting a process based on multi-modal scanning, which can automatically start a process or a sub-process. When the complexity of the instruction sheet is increased, the operation cost of the front-line operators can be greatly reduced, and the production efficiency of the project can be improved.

[0031] A method for automatically starting a process based on multi-modal scanning, in combination with Figure 1 and Figure 2 and specifically includes the following steps.

[0032] Step S1, first click to scan and select the corresponding scanning mode to scan, the PDA end can obtain the corresponding scanning information and perform analysis operation.

[0033] More specifically, the scanning mode described above includes but is not limited to visual recognition, infrared (high environmental adaptability), NFC (near field communication), and ultra-high frequency RFID (long-distance batch identification).

[0034] Generally, the visual recognition described above adopts an integrated camera, of course, other functional devices capable of realizing visual recognition can also be used, which are not limited herein.

[0035] In the embodiment, the scanning mode described above can be dynamically selected according to a scene, of course, when the scanning mode is reselected, the mode switching can also be performed as needed to ensure that the optimal scanning mode can be adopted.

[0036] In the embodiment, the NFC is mainly applicable in a dustproof environment of precision instruments, the infrared is mainly applicable in a high-temperature workshop, the recognition vision such as an integrated camera is applicable to standard bar code or two-dimensional code recognition, and the ultra-high frequency RFID is applicable to logistics pallet batch scanning.

[0037] Through the technical solution described above, the single scanning mode in the prior art is converted into the multi-mode scanning mode of the present application, and the scene adaptability is stronger.

[0038] For step S1, more specifically, it includes the following several sub-steps.

[0039] Step S11, open the ScanService of the PDA end, and then select a scanning mode. Specifically, the selection of the scanning mode can be performed according to an operator, and the operator is dynamically selected as needed according to an actual scene.

[0040] Step S12, on the basis of step S11, initialize according to the selected scanning mode, and then determine whether the initialization operation is successful. If the initialization is successful, subsequent scanning operation will be performed, and then the data obtained by scanning is parsed. If the initialization fails, the scanning mode needs to be reselected for operation.

[0041] In the technical solution, after the specific scanning mode is selected, the initialization operation is performed according to the scanning mode. If the initialization operation is successfully completed, scanning is performed. If the initialization is not successful, the scanning mode needs to be reselected for scanning.

[0042] Step S2, after step S1, determine whether the parsing is successful. If the parsing process is successful, the assembled data initiates a corresponding request to the background server. If the parsing process fails, the scanning needs to be performed again.

[0043] More specifically, the step S2 described above includes the following process: when the parsing is successful, the data after the parsing is called back to the ScanService, the ScanService responds to the callback after scanning, and initiates a request about starting a process to the background server.

[0044] In the technical solution, the parsing and callback process are implemented in the scanning SDK, and the scanning server responds to the callback data and initiates a corresponding request.

[0045] Step S3, after the assembly data in step S2 initiates a request to the background server, the background server queries the corresponding process according to the reference, and sets the process to an open state.

[0046] For the above step S3, more specifically, the following sub-steps are included.

[0047] Step S31, after the background server receives the corresponding request, it searches for the unopened process according to the instruction sheet ID passed.

[0048] Step S32, all unopened processes are traversed until the corresponding unopened process is found, and the process is opened after being found; if the unopened process is not found, a re-scanning operation needs to be performed.

[0049] In the technical solution, the scanning server can respond to the callback data and send a request to the background server, and the background server can perform process traversal according to the received instruction sheet ID.

[0050] Step S4, after step S3, the PDA end automatically queries the corresponding sub-process under the opened process, and sets the first sub-process state to an open state. In this embodiment, the sub-process includes a series of production activities such as material feeding sub-activity.

[0051] For the above step S4, more specifically, the following sub-steps are included.

[0052] Step S41, the client updates the process state and enters the sub-process page.

[0053] Step S42, after entering the sub-process page, it is judged whether there is a sub-process, if there is a sub-process, it is executed according to the order of the sub-process list; if there is no sub-process, a pop-up box is prompted.

[0054] Step S43, in the case of executing according to the order of the sub-process list, it is judged whether the sub-process is successfully opened, if it is successfully opened, the whole process is ended, if it fails to open, the sub-process list is manually refreshed, and the automatic opening of the sub-process function is triggered.

[0055] In the technical solution, the process of the above step S4 can be performed in the client.

[0056] In the prior art, manual operation is required step by step, specifically: scanning → manually starting a process → entering a sub-process list → manually starting a sub-process. For example, after the operator completes the two-dimensional code scanning, the operator needs to manually click "Start Process" on the MES interface, and then enter the sub-process page to start the sub-processes one by one.

[0057] In the present application, the following actions can be automatically triggered by scanning: process automatic starting, the background server directly sets the process state to "start" according to the instruction sheet ID; sub-process chain triggering, after the process is started, the system automatically queries and starts the first sub-process; abnormal processing, if the sub-process fails, the system automatically retries or prompts manual intervention, without returning to the initial interface.

[0058] Compared with the prior art, the present application realizes fully automatic chain execution, reducing manual intervention by more than 70%.

[0059] In the prior art, scanning is only a static information record (such as material traceability), and is not dynamically associated with the production execution process. For example, after scanning the two-dimensional code, only process information is displayed, and manual operation is required to determine the next step.

[0060] In the present application, scanning directly triggers production execution actions, specifically including: real-time state synchronization, process and sub-process state are updated to the client and server in real time; resource dynamic allocation, after the process is started, the related equipment resources (such as machine tools, AGV) are automatically released; data closed loop, scanning data and production execution data (such as working hours, yield) are automatically associated to form a closed loop management of production.

[0061] Compared with the prior art, the present application realizes the production mode of "scanning and execution" from information recording to dynamic execution.

[0062] In the prior art, when scanning fails or data parsing errors occur, manual reoperation is required, and there is a lack of automatic fault tolerance mechanism. For example, after the two-dimensional code is damaged and scanning fails, the operator needs to manually input the instruction sheet ID.

[0063] In the present application, a dynamic retry mechanism is adopted, that is, when parsing fails, the scanning mode is automatically switched (such as from a camera to NFC); instruction sheet intelligent matching, the background server matches similar instruction sheets through fuzzy query, reducing manual intervention; resource release guarantee, whether successful or failed, the scanning resources are automatically released, avoiding system blocking.

[0064] Compared with the prior art, the present application realizes active intelligent fault tolerance from passive manual processing, improving the system robustness.

[0065] Embodiment 2 The embodiment provides a method for automatically starting a process based on multi-mode scanning, and the method can automatically start a process or a sub-process.

[0072] Through the technical solution, the single scanning mode is converted into the multi-mode scanning mode of the application, and the scene adaptability is stronger.

[0073] For step S1, in more detail, the step comprises the following sub-steps.

[0074] In step S11, the ScanService of the PDA end is opened, and then a scanning mode is selected, and specifically, the scanning mode can be selected according to an operator, and the operation tool is dynamically selected according to an actual scene.

[0075] In step S12, based on step S11, initialization is performed according to the selected scanning mode, and then it is judged whether the initialization is successful, if the initialization is successful, subsequent scanning is performed, and then the data obtained by scanning is analyzed; if the initialization fails, the scanning mode needs to be reselected for operation.

[0076] The technical scheme is characterized in that after a specific scanning mode is selected, initialization operation is performed according to the scanning mode, if the initialization operation is successfully completed, scanning is performed, and if the initialization is not successful, the scanning mode needs to be reselected for scanning.

[0077] Step S2, after step S1, it is judged whether the analysis is successful, if the analysis process is successful, the assembled data initiates a corresponding request to the background server, if the analysis process fails, the scanning needs to be reperformed.

[0078] More specifically, the step S2 includes the following process: if the analysis is successful, the data after the analysis is called back to ScanService, ScanService responds to the callback after scanning, and initiates a request to the background server about starting the process.

[0079] In the technical scheme, the analysis and callback process are implemented in the scanning SDK, and the scanning server responds to the callback data and initiates a corresponding request.

[0080] Step S3, after the assembled data initiates a request to the background server in step S2, the background server queries the corresponding process according to the reference, and sets the process to the start state.

[0081] For the above step S3, more specifically, it mainly includes the following substeps.

[0082] Step S31, after the background server receives the corresponding request, it searches for the unstarted process according to the instruction sheet ID passed.

[0083] Step S32, all unstarted processes are traversed until the corresponding unstarted process is found, and the process is started after being found; if the unstarted process is not found, re-scanning operation needs to be performed.

[0084] In the technical scheme, the scanning server can respond to the callback data and send a request to the background server, and the background server can perform process traversal according to the received instruction sheet ID.

[0085] Step S4, after step S3, the PDA end automatically queries the corresponding sub-process under the started process, and sets the first sub-process state to the start state.

[0086] For the above step S4, more specifically, it mainly includes the following several substeps.

[0087] Step S41, the client updates the process state and enters the sub-process page.

[0088] Step S42, after entering the sub-process page, it is judged whether there is a sub-process, if there is a sub-process, it is executed according to the order of the sub-process list; if there is no sub-process, a pop-up box is prompted.

[0089] Step S43, in the case of executing according to the order of the sub-process list, it is judged whether the sub-process is successfully started, if it is successfully started, the whole process is ended, if it fails to start, the sub-process list is manually refreshed, and the function of automatically starting the sub-process is triggered.

[0090] In the technical solution, the process of step S4 can be performed in the client.

[0091] In the prior art, manual operation is required step by step, specifically: scanning → manually starting the process → entering the sub-process list → manually starting the sub-process. For example, after the operator completes the two-dimensional code scanning, the operator needs to manually click “start process” on the MES interface, and then enter the sub-process page to start the sub-process one by one.

[0092] In the present application, the following actions can be automatically triggered by scanning: process automatic starting, the background server directly sets the process state to “start” according to the instruction sheet ID; sub-process chain triggering, after the process is started, the system automatically queries and starts the first sub-process; exception handling, if the sub-process fails, the system automatically retries or prompts manual intervention, without returning to the initial interface.

[0093] Compared with the prior art, the present application realizes fully automatic chain execution, and reduces manual intervention by more than 70%.

[0094] In the prior art, scanning is only static information recording (such as material traceability), and is not dynamically associated with the production execution process. For example, after scanning the two-dimensional code, only process information is displayed, and manual operation is required to determine the next step.

[0095] In the present application, scanning directly triggers production execution actions, specifically including: real-time state synchronization, the process and sub-process states are updated to the client and server in real time; resource dynamic allocation, after the process is started, the related equipment resources (such as machine tools and AGVs) are automatically released; data closed loop, scanning data and production execution data (such as working hours and yield) are automatically associated to form a production closed loop management.

[0096] Compared with the prior art, the present application realizes the production mode of “scanning and executing” from information recording to dynamic execution.

[0097] In the prior art, when scanning fails or data parsing is incorrect, manual reoperation is required, and there is a lack of automatic fault tolerance mechanism. For example, after the two-dimensional code is damaged and scanning fails, the operator needs to manually input the instruction sheet ID.

[0098] In the present application, a dynamic retry mechanism is adopted, that is, when the parsing fails, the scanning mode is automatically switched (such as switching from a camera to NFC);The instruction sheet is intelligently matched, the background server matches similar instruction sheets through fuzzy query, and manual intervention is reduced;Resource release guarantee, whether successful or failed, automatically release scanning resources, avoid system blocking.

[0099] Compared with the prior art, the present application realizes active intelligent fault tolerance from passive manual processing, and improves the system robustness.

[0100] Based on the above embodiment 1, the present embodiment also proposes a system for automatically starting a process based on multi-modal scanning, comprising a client, a scanning SDK, a scanning server and a background server, the client is connected with the scanning SDK, the scanning SDK is connected with the scanning server, and the scanning server is connected with the background server.
