Description

Technical Field

[0001] The present invention mainly relates to the technical field of MES systems, and in particular to a method and system for graphically importing process flows based on an MES system. Background Art

[0002] During the implementation and operation of traditional MES systems, importing and managing process flows is a complex and time-consuming process. Traditional process import methods often rely on text descriptions or tabular records. This approach is not only inefficient but also prone to errors, especially when dealing with complex, multi-step processes. Furthermore, non-graphical representations hinder intuitive understanding and rapid process adjustments. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the present invention provides a method and system for graphically importing process flows based on an MES system, which improves the efficiency of process flow import.

[0004] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0005] A method for graphically importing a process flow based on an MES system comprises the following steps:

[0006] S1. Confirm the process step number: In step management, confirm the detailed steps of each process and their corresponding step numbers;

[0007] S2. Assemble sub-process: graphically select to combine process steps with logical or physical associations into a sub-process and assign a unique sub-process number to each sub-process;

[0008] S3. Build process flow: Use graphical selection to assemble the defined sub-process numbers according to the actual production sequence to form a complete process flow.

[0009] S4. Add sub-process number: Select the corresponding sub-process number in the process flow to add it and automatically adjust the sequence of each step.

[0010] Preferably, the specific process of step S4 is:

[0011] The adding operation is divided into multiple cases: adding the first step, adding the middle step, and adding the last step;

[0012] When adding a sub-process to a process for the first time, except for the first step in the sub-process, the remaining steps in the sub-process number are bound to the previous step in sequence; except for the last step in the sub-process number, the steps in the sub-process number are bound to the next step in sequence; the first step in the first added sub-process will not be bound to the previous step, and the last step in the sub-process will not be bound to the next step;

[0013] When adding a sub-process number for the Nth time, the first step of the Nth sub-process is bound forward to the step of the N-1th sub-process, and the steps in the Nth sub-process number are bound forward to the previous step in sequence. Except for the last step of the sub-process, the steps of the sub-process number are bound backward to the next step in sequence;

[0014] When adding a sub-process number for the last time, the first step of the last sub-process is bound forward to the step of the previous sub-process, and the remaining steps in the last sub-process are bound forward to the previous step in sequence. Except for the last step in the last sub-process, the steps of the sub-process number are bound backward to the next step in sequence; the last step is not bound.

[0015] Preferably, the added process flow has three states: frozen, unfrozen, and activated. When the process flow is in the frozen and activated states, no sub-flows can be added. Sub-flows can only be added when it is in the unfrozen state.

[0016] Preferably, in step S1, the step information includes step type, default recipe, work area, and equipment group number information.

[0017] Preferably, in step S2, the sub-process information includes the sub-process number, sub-process description, type, rework mark, a list of included steps and the logical relationship between the steps.

[0018] Preferably, after step S4, the process flow is further automated, including dependency verification: if the last step of sub-process A is bound to the first step of sub-process B, sub-process B is prohibited from reversely binding to sub-process A;

[0019] Break detection: If there are unbound isolated steps in the process, highlight them and prevent the process from being released;

[0020] Binding is to establish a one-way or two-way dependency relationship through the step number, and the dependency relationship is stored in the form of a database association table.

[0021] The present invention also discloses a computer program product, comprising a computer program, which executes the steps of the above method when executed by a processor.

[0022] The present invention further discloses a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the method described above are executed.

[0023] The present invention also discloses a process flow graphical import system based on the MES system, comprising a memory and a processor connected to each other, wherein the memory stores a computer program, and when the computer program is run by the processor, the steps of the above method are executed.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] The present invention solves the problems of low efficiency and easy errors in the configuration of production process in traditional technologies, realizes the graphical import of process flow, and has the following advantages:

[0026] Improved process flow import efficiency: Graphical representation makes process flow import more intuitive and convenient. Compared to traditional text or table formats, the graphical interface can more quickly display and understand complex process flows, thus shortening import time.

[0027] Enhanced process visualization and comprehensibility: Through graphical representation, the various steps and sub-processes within the process, as well as the logical relationships between them, can be clearly displayed. This visual representation not only helps production managers quickly understand the entire process but also facilitates real-time monitoring and adjustments during production.

[0028] The graphical representation method uses an intuitive graphical interface to graphically display the various steps, sub-processes and the logical relationships between them in the process flow, making the import, viewing, modification and sharing of the process flow more efficient and convenient.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 As shown, the method for graphically importing a process flow based on an MES system provided by an embodiment of the present invention includes the following steps:

[0039] S1. Confirm the process step number: In step management, confirm the detailed steps of each process and their corresponding numbers (step numbers); step information includes step type, default recipe, work area, and equipment group number information;

[0040] S2. Assemble sub-processes: On the sub-process page, you can graphically select to combine logically or physically related process steps into a sub-process and assign a unique sub-process number to each sub-process. The sub-process will merge and center duplicate sub-process numbers in the table, providing a concise and easy-to-understand sub-process viewing page. Added sub-processes include rework sub-processes and normal sub-processes, which are identified and distinguished by different tags.

[0041] S3. Build a process flow: In the MES system, on the process flow page, you can graphically select the defined sub-process numbers and assemble them according to the actual production sequence to form a complete process flow. The process flow will display the repeated sub-flow program numbers and sub-process numbers in the table and merge them into the center, providing a concise and easy-to-understand process flow viewing page.

[0042] S4. Add sub-process number: Select the corresponding sub-process number in the process flow to import and automatically adjust the order of each step; the added process flow has three states: frozen, unfrozen, and activated. When the process flow is in the frozen and activated states, sub-processes cannot be added. Sub-processes can only be added in the unfrozen state.

[0043] Specifically, in step S4, the specific process of importing the sub-process through graphical selection is as follows:

[0044] There are multiple cases in the adding operation: adding the first step, adding the middle step, and adding the last step.

[0045] When adding a sub-process to a process for the first time, except for the first step in the sub-process, the remaining steps in the sub-process number will be bound to the previous step in sequence; except for the last step in the sub-process number, the steps in the sub-process number will be bound to the next step in sequence; the first step in the first added sub-process will not be bound to the previous step, and the last step in the sub-process will not be bound to the next step;

[0046] When adding a sub-process number for the Nth time, the first step of the Nth sub-process is bound forward to the step of the N-1th sub-process, and the steps in the Nth sub-process number are bound forward to the previous step in sequence. Except for the last step of the sub-process, the steps of the sub-process number are bound backward to the next step in sequence;

[0047] When adding a sub-process number for the last time, the first step of the last sub-process is bound forward to the step of the previous sub-process, and the remaining steps in the last sub-process are bound forward to the previous step in sequence. Except for the last step in the last sub-process, the steps of the sub-process number are bound backward to the next step in sequence; the last step is not bound.

[0048] The present invention solves the problems of low efficiency and easy errors in the configuration of production process in traditional technologies, realizes the graphical import of process flow, and has the following advantages:

[0049] Improved process flow import efficiency: Graphical representation makes process flow import more intuitive and convenient. Compared to traditional text or table formats, the graphical interface can more quickly display and understand complex process flows, thus shortening import time.

[0050] Enhanced process visualization and comprehensibility: Through graphical representation, the various steps and sub-processes within the process, as well as the logical relationships between them, can be clearly displayed. This visual representation not only helps production managers quickly understand the entire process but also facilitates real-time monitoring and adjustments during production.

[0051] The graphical representation method uses an intuitive graphical interface to graphically display the various steps, sub-processes and the logical relationships between them in the process flow, making the import, viewing, modification and sharing of the process flow more efficient and convenient.

[0052] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0053] S1. Initialization and preparation

[0054] Step definition: First, according to production requirements, define the specific information of each process step in the MES system, including step number, step description, step type, etc., to ensure that each process step has a unique step number and detailed step information, such as Figure 2 shown.

[0055] S2. Sub-process construction

[0056] Sub-process assembly: Next, according to the logical relationship of the production process, the related process steps are combined into sub-processes.

[0057] Each sub-process is assigned a unique sub-process number and contains the step numbers of all its internal steps. Sub-process information includes but is not limited to sub-process number, sub-process description, type, rework mark, list of included steps and logical relationships between steps, such as Figure 3 shown.

[0058] S3. Process flow construction

[0059] Process assembly: In the MES system, a complete process is constructed by selecting and adding sub-process numbers through a graphical interface. Each sub-process number is considered as a whole in the process and can contain multiple steps. The process information includes the process number, process description, version list and its order, etc. Figure 4 and Figure 7 shown.

[0060] S4. Graphical import and editing

[0061] Add operation: In the graphical interface, three add operations are supported: add first step, add middle step, and add last step. According to actual needs, users can choose the appropriate adding method (default is to add backward) to add steps or sub-processes to the process flow, such as Figure 5-Figure 6 、 Figure 8 shown.

[0062] Subprocess binding:

[0063] Adding a sub-process for the first time: When adding a sub-process for the first time, except for the first step which will not be bound forward, the other steps in the sub-process will be bound forward to the previous step in sequence; at the same time, except for the last step which will not be bound backward, the other steps will also be bound backward to the next step in sequence.

[0064] Subsequent addition of sub-processes: When adding a new sub-process based on an existing sub-process, the first step of the new sub-process will be forward bound to the last step of the previous sub-process, and the other steps in the new sub-process will also follow the forward and backward binding rules.

[0065] Add a sub-process for the last time: The first step of the last sub-process will be bound forward to the last step of the previous sub-process, and its internal steps also follow the binding rules, but the last step is no longer bound backward because it is the end of the entire process.

[0066] S5. Process verification and adjustment

[0067] Verification process: After completing the construction of the process flow, the system should automatically verify whether the logical relationship between the steps and sub-processes is correct, and whether there are any omissions or incorrect bindings.

[0068] Adjust the process: If problems are found, users can make adjustments through the graphical interface, including deleting sub-processes, rebinding steps, etc. In practical applications, deletion and adjustment are indispensable.

[0069] Specifically, the process can be verified through automated verification, including dependency verification: if the last step of sub-process A is bound to the first step of sub-process B, sub-process B is prohibited from reversely binding to sub-process A; break detection: if there are unbound isolated steps in the process, the system will highlight and prevent the process from being released; binding is to establish a one-way or two-way dependency relationship through the step number, and the dependency relationship is stored in the form of a database association table.

[0070] S6.Process Application

[0071] Release process: After verification, the process flow will be released to the MES system for use by the production department.

[0072] Execution monitoring: During the production process, the MES system monitors the execution of the process in real time to ensure that production activities are carried out in accordance with the established process.

[0073] Through the above specific implementation methods, we can clearly see the operation process and application scenarios of the process flow graphical import method based on the MES system.

[0074] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should be considered within the scope of protection of the present invention.
