Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of production management, and particularly relates to an intelligent manufacturing management system. BACKGROUND

[0002] The whole life cycle of a product generally includes stages of design, production and processing, assembly, debugging and acceptance, sales, after-sales maintenance, and scrapping, and when operations are performed in all the stages, a form of a ledger ticket is generally used as a basis for managing the product, the ledger ticket is basically a designer's drawing, a production and processing personnel's manual level of operation content, etc., and a management personnel makes a daily report, a weekly report, and a monthly report by integrating the above ledger tickets, so as to verify the progress or effect of each stage, such as the progress of each process in production and processing, the quality effect (the number of good and bad products), which is used as a basis for later accountability and traceability.

[0003] However, the above ledger tickets are mostly in the form of paper which is inconvenient to store and easy to lose, and even if the ledger tickets are input on line by using a computer or other intelligent system for storage, the above mass of ledger tickets still need to be manually integrated, which easily leads to the problem of low management efficiency. SUMMARY

[0004] In order to improve the management efficiency of intelligent manufacturing, the present application provides an intelligent manufacturing management system.

[0005] The present application provides an intelligent manufacturing management system, which comprises a product management module, a process management module, and a station management module.

[0006] The product management module is used for acquiring basic information of spare parts or products, and storing the basic information in a preset basic information database.

[0007] The process management module is used for defining and storing a process and a process task of each process, matching station information for each process, and sending a process task to a corresponding station management module based on a matching relationship between the process and the station information.

[0008] The station management module is used for acquiring and displaying the process task, and acquiring working data of a station in real time, and transmitting the working data to the process management module, wherein the process task contains the basic information of the spare parts or the products.

[0009] The process management module is further used for acquiring and storing the working data, and generating and outputting working data meeting a search condition in the search condition when a search instruction is received.

[0010] By adopting the technical scheme, the product management module is used for storing and managing basic information of products or parts required for producing the products, wherein the basic information can include two-dimensional or three-dimensional drawings, names, sizes, etc. of the products or parts. The process management module can be used for splitting a machining process of the products into a plurality of processes according to the machining process, each process corresponding to a process task and a work station for completing the process task, and dispatching the process task to the corresponding work station management module. The process management module can claim and display the process task, so as to enable a worker on the work station to execute the corresponding process task. The work station management module further acquires work data of the work station and transmits the work data to the process management module for storage. The process management module can improve a retrieval function, that is, according to different retrieval conditions, to realize integration of the work data. For example, if the process is taken as the retrieval condition, then all work data corresponding to the process is output, so as to realize integration of all work data of the same process. If the retrieval condition is a time period, then work data generated in the time period is output, so as to finally realize stable storage and management of the data, improve integration and export efficiency of the data, and reduce time and labor caused by manual intervention.

[0011] Optionally, the product management module is used for generating a first identifier for each part or product, and establishing an association between the first identifier and the basic information. The first identifier is used for distinguishing different types of parts or different types of products. The process task contains the first identifier of the product or part required for the corresponding process.

[0012] The intelligent manufacturing management system further includes an information identification module. The work station management module is further used for sending an identification instruction to the identification module when the process task is received. The identification instruction at least includes the first identifier.

[0013] The information identification module is used for identifying the first identifier when the identification instruction is received, and feeding back the basic information associated with the first identifier to the corresponding work station module.

[0014] The work station management module is used for receiving and displaying the basic information fed back by the information identification module.

[0015] By adopting the technical scheme, since the basic information of the parts or products generally includes name, size specification, and even two-dimensional drawing, three-dimensional drawing, and production processing matters, etc., the content is too complicated, when the process management module defines the process and process task and sends the process task to the corresponding station management module, all the basic information of the parts or products used in the corresponding process needs to be called from the product management module, and part of the content is easy to be missed, therefore, the first identifier is specially set, when the process and process task are defined, only the first identifier of the corresponding process needs to be called, and when the station management module receives the process task distributed by the process management module, an instruction of identifying the first identifier in the process task can be sent to the information identification module, and the basic information fed back by the information identification module is received and displayed.

[0016] Optionally, the station management module is further used for generating a second identifier for each product or part produced by the station, the second identifier is used for distinguishing the parts or products produced by different stations at different times, and the work data includes the second identifier and corresponding station information.

[0017] By adopting the technical scheme, the second identifier is set to distinguish the products or parts produced by different stations or the same station at different times, the difference between the first identifier and the second identifier is that the second identifier of each product corresponding to the same first identifier is different, the limitation of the second identifier can associate the product with the station producing the product, and even the worker of the station, so that the management personnel can determine the work efficiency and yield of each worker based on this in the subsequent period, and trace back to the individual.

[0018] Optionally, the process management module is further used for defining the process attribute and establishing the association relationship for each process according to the process task and the time sequence of the process task execution.

[0019] When there is a close-following relationship between two processes, the process attribute of the process with earlier process task execution time is added, and the process attribute of the other process is added.

[0020] The process management module is further used for periodically predicting whether a supply-demand imbalance will occur between the processes with the close-following relationship, if yes, a reminder message is sent to the station management module of the station corresponding to the process with the previous attribute, so that the station management module displays the reminder message.

[0021] By adopting the technical scheme, the tight-after relationship refers to that the output of one of the two processes is the raw material of the other process; the application can predict the two processes with the tight-after relationship to predict whether a supply-demand imbalance will occur, and if so, a warning message can be sent to the station management module of the corresponding station to timely remind the staff of the corresponding station to timely adjust the work efficiency and work progress.

[0022] Optionally, the process management module is configured to periodically determine the unit time material consumption a of the process with the subsequent attribute and the unit time material output b of the process with the previous attribute; if the two processes with the tight-after relationship do not satisfy a < b, it is determined that a supply-demand imbalance will occur, otherwise not.

[0023] By adopting the technical scheme, if a < b is not satisfied, it means that the material output of the process with the previous attribute cannot keep up with the consumption of the material by the process with the subsequent attribute, which will lead to the process with the subsequent attribute needing to wait for the output speed of the process with the previous attribute by reducing efficiency or even stopping.

[0024] Optionally, the process management module is configured to periodically determine, from the two processes with the tight-after relationship, the unit time material consumption a of the process with the subsequent attribute, the unit time material output b of the process with the previous attribute, and the unit time material transmission c when the process with the previous attribute transmits the material to the process with the subsequent attribute; if the two processes with the tight-after relationship do not satisfy a ≤ c ≤ b, it is determined that a supply-demand imbalance will occur.

[0025] The process management module is further configured to adjust the speed of c to satisfy a ≤ c ≤ b when it is determined that a supply-demand imbalance exists.

[0026] By adopting the technical scheme, whether a supply-demand imbalance will occur between the two processes with the tight-after relationship is related to the supply speed (i.e., b), the consumption speed (i.e., a), and the transmission speed (i.e., c); if the transmission amount (i.e., c) in the unit time is less than the material consumption (i.e., a) in the unit time, a supply-demand imbalance will occur due to the problem that transmission cannot keep up with consumption; if the material output (i.e., b) in the unit time is less than the material transmission (i.e., c) in the unit time, a supply-demand imbalance will occur due to the problem that supply cannot keep up.

[0027] Optionally, the process management module can match a plurality of station information for each process; and the number of stations corresponding to the process with the previous attribute is consistent with the number of stations corresponding to the process with the subsequent attribute in the two processes with the tight-after relationship.

[0028] The process management module is configured to establish the correlation between processes and establish the correlation between the corresponding station information when the correlation is established for the processes;

[0029] The process management module is further configured to, when it is determined that the supply-demand imbalance will occur, take the process with the preceding sequence attribute corresponding to the supply-demand imbalance as a first process, take the process with the subsequent sequence attribute corresponding to the supply-demand imbalance as a second process, and determine the number of stations of the first process;

[0030] The process management module is further configured to, if the number of stations is unique, adjust the c to satisfy a≤c≤b;

[0031] The process management module is further configured to, if the number of stations is not unique, generate all combinations based on all station information of the first process and all station information of the second process; each combination includes a plurality of corresponding relationships, each corresponding relationship is a one-to-one correspondence relationship between any station of the second process and any station of the third process, each station in the same combination only appears in a unique corresponding relationship, and the number of corresponding relationships in the same combination is consistent with the number of stations of the first process or the second process;

[0032] The process management module is further configured to determine an optimal combination from all combinations based on a preset rule;

[0033] The process management module is further configured to re-establish the correlation between the station information corresponding to the first process and the second process based on the corresponding relationship in the optimal combination.

[0034] By adopting the technical scheme, one process can be equipped with multiple stations, and the multiple stations each independently perform the same process task; therefore, when establishing the association relationship, the process management module not only establishes the association relationship between processes and processes, but also establishes the association relationship between station information and station information, so that each station of the first process can be one-to-one corresponding to any station of the second process, and the supply between stations with a close relationship is ensured; for example, the process with the previous sequence attribute (i.e., the first process) corresponds to three stations A, B, and C, and the process with the subsequent sequence attribute (i.e., the second process) corresponds to three stations D, E, and F; therefore, at the beginning, the process management module combines A, B, C with D, E, and F, such as forming a combination with the following three corresponding relationships: (A, D), (B, E), and (C, E); when the production is performed according to the above combination, the process management module finds that any combination will appear a situation of supply not meeting demand; the process management module finds all combinations of the stations corresponding to the above two processes, if the combination is unique, then c is directly adjusted to meet the condition of a≤c≤b, if the combination is not unique, then the optimal combination is found, and the association relationship (i.e., one-to-one corresponding relationship) between the station information corresponding to the first process and the second process is re-established according to the optimal combination.

[0035] Optionally, the process management module is further configured to draw and display a production flow chart according to the association relationship between processes; and highlight the process with the situation of supply not meeting demand on the production flow chart according to a preset display rule when the situation of supply not meeting demand exists between processes with a close relationship.

[0036] By adopting the technical scheme, the production flow chart is drawn and displayed to clearly know the relationship between processes by the management personnel, at the same time, by judging whether the situation of supply not meeting demand exists, and highlighting the process with the situation of supply not meeting demand when the situation exists, the production efficiency of the corresponding process is known by the management personnel, and the subsequent processing scheme is formulated, such as reminding the previous process to improve the efficiency or add the station of the previous process when the situation of supply not meeting demand exists, so as to increase the supply amount of the previous process.

[0037] Optionally, the station management module is further configured to send a review application to the process management module when receiving a review instruction.

[0038] The process management module is configured to, upon receiving the inquiry application, determine a process corresponding to the process management module that sent the inquiry application and a process having a subsequent relationship with the process, generate a partial flowchart, and feed back the partial flowchart to the corresponding process management module; wherein the partial flowchart at least includes the process corresponding to the process management module, the process having a relationship with the process, and a determination result of whether there is a supply-demand imbalance between the processes.

[0039] The process management module is configured to receive and display the partial flowchart.

[0040] By using the above technical solution, the staff at each process management module can trigger the inquiry instruction to view the process at the process where the staff is located, the process having a relationship with the process, and whether there is a supply-demand imbalance between the processes, so as to ensure that the processes having a relationship can coordinate and cooperate with each other, and avoid the problem of supply-demand imbalance caused by low individual work efficiency.

[0041] Optionally, the intelligent manufacturing management system further comprises an action control verification module, which is configured to verify the product quality based on a preset verification rule and output and display the verification result.

[0042] By using the above technical solution, the quality of the product produced is automatically verified, and the verification result is output, that is, automatic and efficient quality inspection of the product is realized.

[0043] In summary, the present application has at least one of the following beneficial technical effects:

[0044] 1. In the present application, the product management module is configured to store and manage basic information of a product or a component required for producing the product, wherein the basic information can include a two-dimensional or three-dimensional drawing, name, size, etc. of the product or the component, the process management module can be used to split a machining process of the product into a plurality of processes according to the machining process, each process corresponds to a process task and a process station for completing the process task, and the process management module can assign the process task to the corresponding process station, claim and display the process task, and the staff at the process station can execute the corresponding process task, the process station management module can also acquire work data of the process station and transmit the work data to the process management module for storage, and the process management module can improve the inquiry function, that is, according to different search conditions, the work data can be integrated, for example, if the process is used as the search condition, all the work data corresponding to the process is output, the work data of the same process is integrated, and if the time period is used as the search condition, the work data generated in the time period is output, finally, the data is stably saved and managed, the integration and export efficiency of the data is improved, and the time-consuming and labor-intensive problem caused by manual intervention is reduced.

[0045] 2. Further, since the basic information of the parts or products generally includes name, size specification, and even two-dimensional drawing, three-dimensional drawing, production processing matters, etc., the content is too complicated, when the process management module defines the process and process task, and sends the process task to the corresponding station management module, it is easy to miss some content when calling all the basic information of the parts or products used in the corresponding process from the product management module, therefore, the first identifier is specially set, when defining the process and process task, only the first identifier of the corresponding process is called, and when the station management module receives the process task distributed by the process management module, the instruction of identifying the first identifier in the process task can be put forward to the information identification module, and then the basic information fed back by the information identification module is received and displayed;

[0047] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed to be used in the embodiment description will be briefly introduced. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor.

[0048] Figure 1 is a structural block diagram of an intelligent manufacturing management system disclosed in the embodiments of the present application.

[0050] The following will be combined with the drawings Figure 1 The present application will be further described in detail.

[0051] The embodiments of the present application disclose an intelligent manufacturing management system. Referring to Figure 1The intelligent manufacturing management system comprises a product management module 1, a process management module 2 and a station management module 3; wherein the product management module 1 is communicatively connected with a peripheral design platform 6, the design platform 6 is used to send basic information of a designed product or spare part to the product management module 1, the basic information comprises a two-dimensional and three-dimensional model of the product or spare part, and two-dimensional and three-dimensional models of a national standard part and a purchased part required for product assembly, and production and processing matters needing attention of each spare part. The product management module 1 is used to receive the above basic information, generate a first identification for each spare part or product, associate the first identification with the basic information, and store the first identification and the corresponding basic information in a preset basic information database. Wherein the first identification refers to an identification used to distinguish different types of spare parts or products, which can exist in the form of a two-dimensional code.

[0052] The process management module 2 is used to define and store a process and a process task of each process, and match station information for each process. Wherein the worker can access the intelligent manufacturing management system through a webpage, and trigger a process definition instruction through a new process button and a process definition button preset on a webpage interface of the intelligent manufacturing management system. The process management module 2 is used to receive the process definition instruction, display a definition box in which a process name (such as drilling, cutting or assembly, etc.) can be entered, and simultaneously call and display all basic information in the basic information database for the worker to select. When the worker selects a first identification of any basic information, the first identification will be added to the definition box. When the worker completes the selection, the process management module 2 generates a process task with the first identification, realizing the definition of the process and the process task of the process.

[0053] In addition, the station is used for the worker to perform a process task, and the station information comprises position information and / or a station name (such as a drilling station, a cutting station, etc.) of the station. The worker can match station information for each process through the process management module 2, so that the worker of the corresponding station performs the process task of the process. In addition, the same process can correspond to multiple stations, and the multiple stations complete the process task of the corresponding process independently of each other. At this time, the position information or the station name can be numbered to distinguish different stations.

[0054] The process management module 2 is also configured to send a process task to the corresponding work station management module 3 based on the matching relationship between the process and the work station information, wherein the process task contains only the first identifier. In the embodiment of the present application, one work station management module 3 is configured to correspond to each work station, and all the process management modules 2 are communicatively connected to the information identification module 4. The work station management module 3 is configured to receive the process task transmitted by the process management module 2, and send an identification instruction to the information identification module 4 when receiving the process task. The identification instruction contains at least all the first identifiers corresponding to the process task. The information identification module 4 is configured to identify the first identifiers and obtain the basic information corresponding to the first identifiers when receiving the identification instruction, and feed back the obtained basic information to the corresponding work station management module 3. The work station management module 3 is also configured to receive and display the basic information fed back by the information identification module 4, so that the staff of the corresponding work station can know and perform the process task.

[0055] When the product is out of or into the warehouse, the warehouse manager can trigger an out-of-warehouse registration instruction or an into-warehouse registration instruction through the information identification module 4. The out-of-warehouse registration instruction or the into-warehouse registration instruction contains the first identifier of the product out of or into the warehouse. The information identification module 4 is also configured to identify the first identifier and update the quantity of the product in the preset warehouse database when receiving the out-of-warehouse registration instruction or the into-warehouse registration instruction.

[0056] The process management module 2 is also configured to detect the corresponding work station in real time to obtain work data, and transmit the work data to the process management module 2. Correspondingly, the process management module 2 can receive and store the work data, and generate and display the work data meeting the search condition of the review instruction based on the search condition of the review instruction when receiving the review instruction triggered by the manager. The work data can be the work log manually input by the corresponding staff to the corresponding work station management module 3, or the monitoring data obtained by the work station management module 3 in real time, such as the image content of the work station and the surrounding area of the work station captured by the camera device of the work station management module 3. The search condition can be a specific time period, a specific work station information or a process name, etc.

[0057] In addition, the workstation management module 3 is further configured to generate a second identifier for a product or a component when the product or the component is produced by the corresponding workstation, the second identifier being used to distinguish components or products produced by different workstations at different times, and can be embodied in the form of a number; correspondingly, the work data includes the second identifier, the workstation information of the corresponding workstation, and can further include the marking time of the second identifier, the identity information of the worker of the corresponding workstation, etc.; in addition, the workstation management module 3 can include a device for marking the second identifier on the product or the component, such as a spraying device, for marking the second identifier on the corresponding product or component. Correspondingly, the information recognition module 4 is further configured to recognize the second identifier, so as to output the work data of the corresponding product by recognizing the second identifier.

[0058] Since a process refers to a specific step in a specific production process, it can be known that a complete production process generally consists of multiple processes, and according to the execution time of the process task, some processes will have a correlation relationship with each other, and the correlation relationship can include a close-following relationship and a parallel relationship. The two processes with the close-following relationship have the following characteristics: the product generated by the process task of one of the processes is the raw material for the process task of the other process, that is, the process task of the latter process can only be executed on the premise that the former process is completed; correspondingly, the two processes with the parallel relationship have the following characteristics: the process tasks of the two processes are different and do not interfere with each other, and the process tasks of the two processes do not have a time sequence and can be performed simultaneously.

[0059] The workstation management module 3 is configured to define the process attribute for each process according to whether there is a correlation relationship between any processes, and specifically, the workstation management module 3 is configured to add a preceding attribute to the process with an earlier execution time of the process task and add a subsequent attribute to the other process when there is a close-following relationship between the two processes.

[0060] Correspondingly, the process management module 2 is further configured to store the correlation relationship between the processes with the correlation relationship, such as the close-following relationship between the process X and the process Y and the process Z, thereby forming two sets of correlation relationships, i.e., the process X-process Y and the process X-process Z, and the process attribute of the process in the correlation relationship can also be stored in the correlation relationship, such as the process X being completed before the process Y and after the process Z, so that the process attribute of the process X in the correlation relationship of the process X-process Y is the preceding attribute, and the process attribute of the process X in the correlation relationship of the process X-process Z is the subsequent attribute; correspondingly, the above correlation relationship can be represented as: process X (preceding attribute)-process Y (subsequent attribute), process X (subsequent attribute)-process Z (preceding attribute).

[0061] The process management module 2 is also used to periodically predict any one group of two processes with close sequence relationship to predict whether a shortage situation will occur, wherein the shortage situation refers to that the process with the preceding attribute fails to provide raw materials for the process with the subsequent attribute, which easily leads to the reduction or even stagnation of production efficiency.

[0062] The determination method of whether the shortage situation will occur is as follows:

[0063] Method 1 is suitable for the case that the work station of the process with the preceding attribute is adjacent to the work station of the process with the subsequent attribute, and the raw materials produced by the work station of the process with the preceding attribute can be immediately supplied to the work station of the process with the subsequent attribute for use, i.e. the production is used immediately. Specifically, the process management module 2 determines the unit time raw material consumption a of the process with the subsequent attribute, and determines the unit time raw material output b of the process with the preceding attribute. If a < b is not satisfied, it is determined that the shortage situation will occur, otherwise, it does not exist.

[0064] Method 2 is suitable for the case that the raw materials produced by the work station of the process with the preceding attribute need to be transported (such as by a conveyor belt) for a certain distance before reaching the work station of the process with the subsequent attribute for use. Correspondingly, the process management module 2 determines the unit time raw material consumption a of the process with the subsequent attribute, the unit time raw material output b of the process with the preceding attribute, and the unit time raw material transmission c of the process with the preceding attribute to the process with the subsequent attribute. If a ≤ c ≤ b is not satisfied, it is determined that the shortage situation will occur.

[0065] It is to be noted that a and b are determined by the working efficiency of the corresponding work station staff or automatic equipment. The process management module can determine a and b by determining the number of the second marks generated in a unit time (such as 1 minute), and calculate the unit time raw material transmission c through the photoelectric switch preset on the conveyor belt.

[0066] When the process management module 2 determines that a shortage will occur, the process with the preceding attribute corresponding to the shortage is taken as the first process, the process with the subsequent attribute is taken as the second process, the number of stations of the first process or the second process is determined, and a corresponding processing scheme is given based on the number of stations. It should be noted that, as known from the foregoing, each process can be matched with multiple stations to independently perform the process task of the process, and because there can be a close-following relationship between processes, in order to enable each station corresponding to the first process in the process with the close-following relationship to correspond to a station of the second process, that is, to achieve a one-to-one correspondence relationship, the application limits that the number of stations of the first process with the close-following relationship is consistent with the number of stations of the second process, and when the association relationship is established, the station of the first process will correspond to a unique station of the second process to establish a corresponding relationship. For example, the first process X has three stations A, B, and C, and the second process Y has three stations C, D, and E. When the association relationship is initially established, the process management module 2 will not only establish an association relationship between the first process X and the second process Y, but also establish a one-to-one corresponding relationship between the station information, such as (A, C), (B, D), and (C, E). The corresponding relationship needs to ensure that each station of the first process corresponds to only one unique station of the second process.

[0067] If the number of stations (i.e., the number of stations of the first process or the number of stations of the second process) is unique, the c is adjusted so that the adjusted c satisfies a≤c≤b.

[0068] If the number of stations is not unique, based on all station information of the first process and all station information of the second process, all combinations are generated, wherein each combination includes a plurality of corresponding relationships, each corresponding relationship is a one-to-one correspondence relationship between any station of the second process and any station of the third process, each station only appears in a unique corresponding relationship in the same combination, and the number of corresponding relationships in the same combination is consistent with the number of stations of the first process or the second process. The above exemplary (A, C), (B, D), and (C, E) related to the first process X and the second process Y are one of the combinations, the process management module 2 will list all combinations, and based on a preset rule, determine an optimal combination from all combinations, and based on all corresponding relationships of the optimal combination, reestablish the association relationship between the station information of the first process and the second process, that is, reestablish the corresponding relationship between the stations.

[0069] The preset rule is specifically that: determining whether each corresponding relationship in the same combination satisfies a≤c≤b, determining the proportion value of the corresponding relationship satisfying a≤c≤b, and determining the adjustment amplitude value of adjusting the corresponding c to satisfy a≤c≤b from each corresponding relationship not satisfying a≤c≤b. If there is any combination corresponding to the calculated proportion value greater than the preset proportion value, the combination with the greatest proportion value greater than the preset proportion value is selected as the optimal combination. If the calculated proportion value of all combinations is not greater than the preset proportion value, the adjustment amplitude value of c in each corresponding relationship not satisfying a≤c≤b in each combination is calculated, the total adjustment amplitude value of each combination is calculated, and the combination with the smallest total adjustment amplitude value is selected as the optimal combination.

[0070] With reference to Figure 1 The process management module 2 is further configured to draw and display a production flowchart according to the association relationship between the processes. The production flowchart at least includes all the processes arranged in the order of execution time of the process tasks, and the processes having the immediate-after relationship are connected by line segments with arrows to reflect the relationship between the processes and the execution order of the processes.

[0071] The process management module 2 is further configured to highlight the process determined to have the situation of supply not meeting demand in the production flowchart according to a preset display rule when it is determined that there will be a situation of supply not meeting demand between the processes having the immediate-after relationship. The preset display rule can be to distinguish the process from the process without the situation of supply not meeting demand by different colors.

[0072] In addition, the station management module 3 is further configured to send a review application to the process management module 2 when receiving a review instruction. The process management module 2 is configured to determine the process corresponding to the station management module 3 sending the review application and the process having the immediate-after relationship with the process when receiving the review application, generate a local flowchart, and feed back the local flowchart to the corresponding station management module 3. The local flowchart can be a part of the production flowchart, which specifically can include the process corresponding to the process management module 2, the process having the association relationship with the process, and the determination result of whether there is the situation of supply not meeting demand between the processes. The determination result is embodied in whether there is a highlighted process. Specifically, if there is the situation of supply not meeting demand, the process determined to have the situation of supply not meeting demand is highlighted on the local flowchart according to the preset display rule. The station management module 3 is configured to receive and display the local flowchart.

[0073] With reference to Figure 1The intelligent manufacturing management system further comprises an action control verification module 5. Specifically, the action control verification module 5 comprises an action control unit, a verification unit and a verification result output unit. The control unit is configured to control the action of the product manufactured. The verification unit is configured to verify whether the action of the product is appropriate according to the read-in embedded information (i.e. the preset verification rule).

[0074] The working principle of the intelligent manufacturing management system disclosed by the embodiments of the present application is as follows: a designer can input the basic information of each product or spare part through a design platform 6. The design platform 6 is configured to transmit the aforementioned basic information to a product management module 1. The product management module 1 is configured to obtain the aforementioned basic information, and automatically generate a unique first identifier for each spare part or product. The first identifier is stored in a preset basic information database after the first identifier is associated with the basic information.

[0075] A worker can customize a process, input the process task of the process and match one or more workstations for each process according to the process involved in the entire work flow through a process management module 2. The process management module 2 transmits the defined process task to a workstation management module 3 of the corresponding workstation, so as to identify the first identifier through the workstation management module 3 to obtain the corresponding basic information, and then display the basic information, so that the worker of the corresponding workstation can know the process task to be performed and perform the corresponding process task.

[0076] During the execution of the process task, the workstation management module 3 obtains work data by monitoring the corresponding workstation in real time, and sends the work data to the process management module 2. The process management module 2 integrates the aforementioned process data. A manager can trigger a retrieval instruction to make the process management module 2 retrieve and display the work data that the manager wants to retrieve. Thus, all data in the entire production process can be automatically and efficiently stored and retrieved.

[0077] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
