Description

A production line control system and control method based on MES Technical Field

[0001] This invention relates to the field of production line control systems, specifically a production line control system and control method based on MES. Background Technology

[0002] MES (Manufacturing Execution System) is a management system for shop floor production. It plays a crucial role in optimizing production activities by transmitting information throughout the process from work order issuance to finished product completion. Through real-time and accurate information, MES guides, initiates, responds to, and reports on production activities, rapidly adapting to changes, reducing non-value-added production activities, and improving operational and process efficiency.

[0003] Applying MES to production line control systems can further improve the efficiency of production lines. However, existing production line control systems often focus on the processing, transportation, assembly, and inspection of materials, but neglect the issue of material storage, especially materials nearing their expiration date. If these materials cannot be effectively handled, it can easily lead to serious waste of materials and increase costs.

[0004] Therefore, those skilled in the art provide a production line control system and control method based on MES to solve the problems mentioned in the background art.

[0005] Summary of the Invention

[0006] The purpose of this invention is to provide a production line control system and control method based on MES, which focuses on material storage and can handle near-expiry materials in a timely and effective manner when a large amount of near-expiry materials appear, so as to avoid serious waste of materials, reduce costs, and solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A production line control system based on MES includes a material information acquisition module, a personnel information acquisition module, an equipment information acquisition module, a data receiving module, a data analysis module, a data import module, a central control module, a notification module, and an actuator module.

[0009] The material information acquisition module is used to collect information on the storage quantity of near-expiry materials, the temperature and humidity information of the material warehouse, and the quantity of pests in the material warehouse; the personnel information acquisition module is used to collect information on personnel absent from their posts on the current day; the equipment information acquisition module is used to collect information on equipment failures on the production line on the current day; the data receiving module is used to receive all the collected information and package it to send to the data analysis module; the data import module is used to import preset information into the data analysis module; the data analysis module is used to analyze all the received information and output the analysis results to the central control module; after receiving the analysis results, the central control module issues corresponding control commands to the notification module and the execution mechanism module; the notification module issues corresponding notifications according to the control commands; and the execution mechanism module executes corresponding measures according to the control commands.

[0010] As a further aspect of the present invention: the specific process by which the data analysis module analyzes the information collected by the material information acquisition module is as follows:

[0011] Step 1: Mark the collected near-expiry material storage quantity as A total, the collected material warehouse temperature as C, the collected material warehouse humidity as RH, and the collected material warehouse pest quantity as B. Near-expiry material refers to material with a shelf life of seven days.

[0012] Step 2: Divide the near-expiry materials into seven portions according to the number of days of shelf life, and label them as A1, A2, A3, A4, A5, A6, and A7 respectively;

[0013] Step 3: Compare the real-time temperature C of the material warehouse with the preset temperature c. If C > c, it means that the current internal temperature of the material warehouse is higher than the preset value.

[0014] Step 4: Compare the real-time humidity RH of the material warehouse with the preset humidity rh. If RH > rh, it means that the current humidity inside the material warehouse is higher than the preset value.

[0015] Step 5: Compare the real-time pest quantity B in the material warehouse with the preset pest quantity b. If B > b, it means that the current pest quantity in the material warehouse is higher than the preset value.

[0016] Step Six: Adjust A1, A2, A3, A4, A5, A6, and A7 based on the comparison results of Steps Three, Four, and Five, and output the adjusted a1, a2, a3, a4, a5, a6, and a7.

[0017] Step 7: Match a1, a2, a3, a4, a5, a6, and a7 with the preset daily material consumption A. 日消耗量 Compare the results, and then select the ones greater than A from a1, a2, a3, a4, a5, and a6. 日消耗量The items are allocated to the first sequence, and those less than or equal to A are selected from a1, a2, a3, a4, a5, and a6. 日消耗量 The items are planned to be assigned to the second sequence;

[0018] Step 8: Label a1, a2, a3, a4, a5, and a6 as aj, where j = 1...6. If no item in aj exists in the first sequence, the analysis result is "material is normal". If any item in aj exists in the first sequence, proceed to the next step.

[0019] Step 9: If aj + a(j-1) ≤ 2*A 日消耗量 If the aj is removed from the first sequence, where 2≤j≤6, and if any aj exists in the modified first sequence, the analysis result is output as material anomaly.

[0020] As a further aspect of the present invention: the specific process of adjusting A1, A2, A3, A4, A5, A6, and A7 in step six is ​​as follows:

[0021] If any of the following conditions are met: the current temperature inside the material warehouse is higher than the preset value, the current humidity inside the material warehouse is higher than the preset value, or the current number of pests inside the material warehouse is higher than the preset value, then the output adjustment result will be a1=(A1+0.1A), a2=(A1+0.2A), a3=(A1+0.3A), a4=(A1+0.4A), a5=(A1+0.5A), a6=(A1+0.6A), a7=(A1-2.1A), where A is the preset material quantity;

[0022] If any two of the following conditions are met: the current temperature inside the material warehouse is higher than the preset value, the current humidity inside the material warehouse is higher than the preset value, or the current number of pests inside the material warehouse is higher than the preset value, then the output adjustment result is a1=(A1+0.2A), a2=(A1+0.4A), a3=(A1+0.6A), a4=(A1+0.8A), a5=(A1+A), a6=(A1+1.2A), a7=(A1-4.2A);

[0023] If the current material warehouse temperature, humidity, and pest quantity all exceed the preset values, the output adjustment results will be a1 = (A1 + 0.3A), a2 = (A1 + 0.6A), a3 = (A1 + 0.9A), a4 = (A1 + 1.2A), a5 = (A1 + 1.5A), a6 = (A1 + 1.8A), and a7 = (A1 - 6.3A), where A is the preset material quantity.

[0024] As a further aspect of the present invention: the specific process by which the data analysis module analyzes the information collected by the personnel information collection module is as follows:

[0025] The number of vacancies in each position collected is labeled as Di, i = 1···n, where n is a positive integer;

[0026] Mark the employees who are normally fully staffed in each position as di, i = 1···n;

[0027] Calculate the vacancy rate for each position: Ei = (Di / di);

[0028] Compare Ei with the preset value e. If Ei > e, then Ei is assigned to the third sequence. If Ei ≤ e, then Ei is assigned to the fourth sequence.

[0029] The number of Ei in the third sequence is counted and labeled as F. If F > 0, the output analysis result is "personnel position abnormal"; if F = 0, the output analysis result is "personnel position normal".

[0030] As a further aspect of the present invention: the specific process by which the data analysis module analyzes the information collected by the device information acquisition module is as follows:

[0031] The collected production line equipment failure rate is marked as G, and the preset failure rate is marked as g;

[0032] Compare G with g. If G ≤ g, the output analysis result is that the equipment failure rate is normal.

[0033] If g < G ≤ 2g, the output analysis result is a level one abnormality in equipment failure rate;

[0034] If 2g < G ≤ 3g, the output analysis result is a level 2 abnormality in equipment failure rate;

[0035] If 3g < G, the output analysis result is a level three abnormal equipment failure rate.

[0036] As a further aspect of the present invention: Regarding the analysis results of the information collected by the material information acquisition module, the control command issued by the central control module is specifically as follows:

[0037] If the current internal temperature of the material warehouse is higher than the preset value, a cooling control command is issued to the actuator module;

[0038] If the humidity inside the current material warehouse is higher than the preset value, a dehumidification control command is sent to the actuator module;

[0039] If the number of pests inside the current material warehouse is higher than the preset value, a pest control command is issued to the actuator module.

[0040] If the analysis results show material anomalies, then calculate the amount of material to be processed, A. 处理 =(A total-7*A 日消耗量The materials to be processed are extracted from those with the closest expiration date.

[0041] As a further aspect of the present invention: Regarding the analysis results of the information collected by the personnel information collection module, the control command issued by the central control module is specifically as follows:

[0042] If the analysis results indicate abnormal personnel positions, then all on-duty personnel will be reassigned.

[0043] If abnormal personnel status still exists after the job adjustment, a control instruction is issued to the notification module. After receiving the control instruction, the notification module issues a voluntary make-up work notice to the employees who are on leave.

[0044] For employees who voluntarily make up for lost hours, in addition to their lost hour wages, they will be given corresponding contribution points. These contribution points can be used to exchange for materials awaiting processing. Specifically, for each hour of lost work, the employee will be given one contribution point. The exchange of contribution points will be as follows: one contribution point can be exchanged for one kilogram of materials awaiting processing, up to a quantity A of materials awaiting processing. 处理 The materials will be redeemed until all materials are redeemed; if the materials are not redeemed, the remaining materials will be donated to social organizations or charities in need.

[0045] As a further aspect of the present invention, the specific process of the job adjustment is as follows: determine the jobs with a current vacancy rate less than or equal to a preset value from Ei in the fourth sequence, and then select employees from the confirmed jobs to fill the vacancies in the jobs with a vacancy rate greater than the preset value. The selection process needs to meet two conditions: the first condition is that after selecting employees, the vacancy rate of the selected job is still less than or equal to the preset value, and the second condition is that the selected employees have experience working in the job to be filled.

[0046] As a further aspect of the present invention: Based on the analysis results of the information collected by the equipment information acquisition module, the control command issued by the central control module is specifically as follows:

[0047] If the analysis result shows that the equipment failure rate is normal but G>0, the main control module sends a control command to the notification module. After receiving the control command, the notification module notifies any on-duty maintenance personnel to go to the faulty equipment for repair.

[0048] If the analysis result indicates that the equipment failure rate is Level 1 abnormal, the main control module will issue a control command to the notification module. After receiving the control command, the notification module will notify any group of on-duty maintenance personnel to go to the faulty equipment for repair.

[0049] If the analysis result indicates a level 2 abnormality in equipment failure rate, the main control module will issue a control command to the notification module. Upon receiving the control command, the notification module will notify all on-duty maintenance personnel to go to the faulty equipment for repair.

[0050] If the analysis result indicates a Level 3 abnormal equipment failure rate, the main control module will issue a control command to the notification module. Upon receiving the control command, the notification module will notify all on-duty and off-duty maintenance personnel to go to the faulty equipment for repair.

[0051] This application also discloses a production line control method based on MES, applied to an MES-based production line control system, including:

[0052] The material information collection module collects information on the storage quantity of near-expiry materials, the temperature and humidity information of the material warehouse, and the quantity of pests in the material warehouse;

[0053] The personnel information collection module collects information on personnel absent from work on the current day;

[0054] The equipment information acquisition module collects fault information of the production line equipment on the same day;

[0055] The data receiving module receives all the collected information and packages it before sending it to the data analysis module;

[0056] The data import module imports preset information into the data analysis module;

[0057] The data analysis module analyzes all the received information and outputs the analysis results to the central control module;

[0058] After receiving the analysis results, the central control module issues corresponding control commands to the notification module and the actuator module;

[0059] The notification module issues corresponding notifications based on control commands;

[0060] The actuator module executes corresponding measures based on control commands.

[0061] Compared with the prior art, the beneficial effects of the present invention are:

[0062] 1. This application focuses on material storage, enabling timely and effective handling of near-expiry materials when large quantities are present, avoiding significant waste and reducing costs. Specifically, for near-expiry materials with a shelf life of less than one week, adjustments are made based on the daily detection of warehouse temperature, humidity, and pest levels to more accurately estimate the remaining shelf life, allowing for timely and effective handling within that shelf life.

[0063] 2. This application addresses the issue of excessive near-expiry materials, i.e., the amount of material A to be processed. 处理The materials are offered as an employee benefit and can be redeemed by staff who voluntarily come to make up for missed shifts. This reduces inventory and avoids material waste, while also enhancing the sense of belonging among staff who make up for missed shifts. Furthermore, the benefits for staff who make up for missed shifts can increase their enthusiasm for making up for missed shifts. In addition, any unredeemed materials nearing their expiration date can be donated to social organizations or charities in need, which can not only improve the company's social image and reputation, but also expand the market and enhance customer loyalty.

[0065] Figure 2 is a flowchart of a production line control method based on MES. Detailed Implementation

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] As mentioned in the background section of this application, research has found that existing production line control systems often focus on the processing, transportation, assembly, and inspection of materials, but neglect the issue of material storage, especially materials nearing their expiration date. If these materials cannot be effectively handled, it can easily lead to serious waste of materials, increase costs, and has certain shortcomings.

[0068] To address the aforementioned shortcomings, this application discloses a production line control system and method based on MES, which focuses on material storage and can promptly and effectively handle near-expiry materials when a large amount of such materials are present, thereby avoiding serious waste and reducing costs.

[0069] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0070] Please refer to Figure 1. In this embodiment of the invention, a production line control system based on MES includes a material information acquisition module, a personnel information acquisition module, an equipment information acquisition module, a data receiving module, a data analysis module, a data import module, a central control module, a notification module, and an execution mechanism module. The material information acquisition module is used to collect information on the storage quantity of near-expiry materials, the temperature and humidity information of the material warehouse, and the amount of pests in the material warehouse. The personnel information acquisition module is used to collect information on personnel absent from their posts on the current day. The equipment information acquisition module is used to collect fault information of the production line equipment on the current day. The data receiving module is used to receive all the collected information and package it to send to the data analysis module. The data import module is used to import preset information into the data analysis module. The data analysis module is used to analyze all the received information and output the analysis results to the central control module. After receiving the analysis results, the central control module issues corresponding control commands to the notification module and the execution mechanism module. The notification module is used to issue corresponding notifications according to the control commands. The execution mechanism module is used to execute corresponding measures according to the control commands. This application focuses on material storage, and when a large amount of near-expiry materials appear, it can handle the near-expiry materials in a timely and effective manner, avoiding serious waste of materials and reducing costs.

[0071] In this embodiment, the specific process by which the data analysis module analyzes the information collected by the material information collection module is as follows: Step 1: Mark the collected near-expiry material storage quantity as A_total, the collected material warehouse temperature as C, the collected material warehouse humidity as RH, and the collected material warehouse pest quantity as B. Near-expiry materials refer to materials with a shelf life of seven days. Step 2: Divide the near-expiry materials into seven groups according to their shelf life, labeling them A1, A2, A3, A4, A5, A6, and A7 respectively. Step 3: Compare the real-time material warehouse temperature C with the preset temperature c. If C > c, it indicates that the current internal temperature of the material warehouse is within a certain range. Step 4: Compare the real-time humidity RH of the material warehouse with the preset humidity rh. If RH > rh, it means that the current humidity inside the material warehouse is higher than the preset value. Step 5: Compare the real-time pest quantity B of the material warehouse with the preset pest quantity b. If B > b, it means that the current pest quantity inside the material warehouse is higher than the preset value. Step 6: Adjust A1, A2, A3, A4, A5, A6, and A7 according to the comparison results of Steps 3, 4, and 5, and output the adjusted a1, a2, a3, a4, a5, a6, and a7. Step 7: Compare a1, a2, a3, a4, a5, a6, and a7 with the preset daily material consumption A. 日消耗量 Compare the results, and then select the ones greater than A from a1, a2, a3, a4, a5, and a6. 日消耗量 The items are allocated to the first sequence, and those less than or equal to A are selected from a1, a2, a3, a4, a5, and a6. 日消耗量The items are planned to the second sequence; Step 8: Mark a1, a2, a3, a4, a5, a6 as aj, j = 1...6. If no item in aj exists in the first sequence, the output analysis result is "material is normal". If any item in aj exists in the first sequence, proceed to the next step; Step 9: If aj + a(j-1) ≤ 2*A 日消耗量 If the value of aj is not specified, it will be removed from the first sequence, where 2 ≤ j ≤ 6. If any aj exists in the modified first sequence, the analysis result will be output as material anomaly. For materials nearing their expiration date (within one week), adjustments are made based on the warehouse temperature, humidity, and pest count detected on the day of purchase to more accurately predict the remaining shelf life of the materials. Timely and effective handling of the materials within the shelf life is then implemented. It should be noted that, under the same internal conditions, external factors (warehouse temperature, humidity, and pest count) are significant drivers of accelerated material deterioration. More specifically, high temperatures accelerate chemical reactions, promoting oxidation and decomposition; excessive humidity causes materials to absorb moisture, increasing the opportunity for microbial growth and thus accelerating deterioration; and the presence of pests damages the material's structure, further accelerating deterioration.

[0072] In this embodiment, the specific process of adjusting A1, A2, A3, A4, A5, A6, and A7 in step six is ​​as follows: If any one of the following occurs: the current internal temperature of the material warehouse is higher than a preset value, the current internal humidity of the material warehouse is higher than a preset value, or the current internal pest quantity of the material warehouse is higher than a preset value, then the output adjustment result is a1 = (A1 + 0.1A), a2 = (A1 + 0.2A), a3 = (A1 + 0.3A), a4 = (A1 + 0.4A), a5 = (A1 + 0.5A), a6 = (A1 + 0.6A), and a7 = (A1 - 2.1A), where A is the preset material quantity; if ... If both of these conditions are met, the output adjustment results will be a1 = (A1 + 0.2A), a2 = (A1 + 0.4A), a3 = (A1 + 0.6A), a4 = (A1 + 0.8A), a5 = (A1 + A), a6 = (A1 + 1.2A), a7 = (A1 - 4.2A). If the current material warehouse temperature, humidity, and pest quantity are all higher than the preset values, the output adjustment results will be a1 = (A1 + 0.3A), a2 = (A1 + 0.6A), a3 = (A1 + 0.9A), a4 = (A1 + 1.2A), a5 = (A1 + 1.5A), a6 = (A1 + 1.8A), a7 = (A1 - 6.3A), where A is the preset material quantity. When abnormal temperature, humidity, and pest populations occur simultaneously in a warehouse, the storage conditions are at their worst. Under these conditions, the materials in the warehouse deteriorate faster, resulting in materials that could originally be stored for two days only having a shelf life of one day.

[0073] In this embodiment, the specific process by which the data analysis module analyzes the information collected by the personnel information collection module is as follows: The number of vacant positions for each position is marked as Di, i = 1...n, where n is a positive integer; the number of normally full-staffed personnel for each position is marked as di, i = 1...n; the vacancy rate for each position is calculated as Ei = (Di / di); Ei is compared with a preset value e. If Ei > e, Ei is assigned to the third sequence; if Ei ≤ e, Ei is assigned to the fourth sequence; the number of Ei in the third sequence is counted and marked as F. If F > 0, the analysis result is output as "personnel position abnormal"; if F = 0, the analysis result is output as "personnel position normal". This setting can effectively count the vacancy rate for each position. The higher the vacancy rate, the greater the workload of that position, and the slower the processing speed of the product at that position, thus requiring additional personnel to assist.

[0074] In this embodiment, the specific process by which the data analysis module analyzes the information collected by the equipment information acquisition module is as follows: The collected production line equipment failure rate is marked as G, and a preset failure rate is marked as g; G and g are compared. If G ≤ g, the output analysis result is "equipment failure rate is normal"; if g < G ≤ 2g, the output analysis result is "equipment failure rate is level one abnormal"; if 2g < G ≤ 3g, the output analysis result is "equipment failure rate is level two abnormal"; if 3g < G, the output analysis result is "equipment failure rate is level three abnormal". This setting can quickly identify the severity of the current equipment failure; a higher failure rate significantly impacts production line efficiency.

[0075] In this embodiment, the control commands issued by the central control module based on the analysis results of the information collected by the material information acquisition module are as follows: if the current internal temperature of the material warehouse is higher than a preset value, a cooling control command is issued to the execution mechanism module; if the current internal humidity of the material warehouse is higher than a preset value, a dehumidification control command is issued to the execution mechanism module; if the current number of pests in the material warehouse is higher than a preset value, a pest control command is issued to the execution mechanism module; if the analysis results indicate a material abnormality, the amount of material to be processed, A, is calculated. 处理 =(A total-7*A 日消耗量 The materials to be processed are extracted from those with the closest expiration date. The actuator module includes temperature and humidity control equipment and pest control equipment installed in the material warehouse. When the temperature, humidity, or pest quantity becomes abnormal, the actuator module takes corresponding measures to remedy the situation, thereby slowing down the deterioration rate of the materials.

[0076] In this embodiment, the control command issued by the central control module based on the analysis results of the information collected by the personnel information collection module is as follows: if the analysis results indicate personnel job abnormalities, then all on-duty personnel will be reassigned; if personnel job abnormalities still exist after the job reassignment, then a control command will be issued to the notification module, which will then issue a voluntary make-up work notice to employees on leave; for employees who voluntarily come to make up work, in addition to make-up work wages, a corresponding contribution value will be assigned, which can be used to exchange for materials to be processed. The specific assignment of contribution value is as follows: for every hour of make-up work, the employee making up work will be assigned one contribution value; the specific exchange of contribution value is as follows: one contribution value can be exchanged for one kilogram of materials to be processed, until the amount of materials to be processed is A. 处理 The materials will be redeemed until all are redeemed; if any materials are not redeemed, the remaining materials will be donated to social organizations or charities in need. This application applies to excess near-expiry materials, i.e., quantity A of materials to be redeemed. 处理The materials are offered as an employee benefit and can be redeemed by staff who voluntarily come to make up for missed shifts. This reduces inventory and avoids material waste, while also enhancing the sense of belonging among staff who make up for missed shifts. Furthermore, the benefits for staff who make up for missed shifts can increase their enthusiasm for making up for missed shifts. In addition, any unredeemed materials nearing their expiration date can be donated to social organizations or charities in need, which can not only improve the company's social image and reputation, but also expand the market and enhance customer loyalty.

[0077] In this embodiment, the specific process of job adjustment is as follows: Jobs with a vacancy rate less than or equal to a preset value are determined from Ei in the fourth sequence. Then, employees are selected from these confirmed jobs to fill vacancies in positions with a vacancy rate greater than the preset value. Two conditions must be met during the selection process: first, after selecting employees, the vacancy rate of the selected job must still be less than or equal to the preset value; second, the selected employees must have experience working in the position being filled. This setting effectively ensures that job adjustments do not significantly impact the original positions, while also preventing inexperienced employees from hindering the process by being assigned to unfamiliar positions.

[0078] In this embodiment, the control commands issued by the central control module based on the analysis results of the information collected by the equipment information acquisition module are as follows: If the analysis result indicates that the equipment failure rate is normal but G > 0, the central control module issues a control command to the notification module, which then notifies any on-duty maintenance personnel to go to the faulty equipment for repair; if the analysis result indicates a level one abnormality in the equipment failure rate, the central control module issues a control command to the notification module, which then notifies any group of on-duty maintenance personnel to go to the faulty equipment for repair; if the analysis result indicates a level two abnormality in the equipment failure rate, the central control module issues a control command to the notification module, which then notifies all on-duty maintenance personnel to go to the faulty equipment for repair; if the analysis result indicates a level three abnormality in the equipment failure rate, the central control module issues a control command to the notification module, which then notifies all on-duty and off-duty maintenance personnel to go to the faulty equipment for repair. This setting ensures that an appropriate number of personnel can be arranged for repair when the equipment failure rate is high.

[0080] This invention focuses on material storage, enabling timely and effective handling of large quantities of near-expiry materials to avoid significant waste and reduce costs. Specifically, for materials with a shelf life of less than one week, adjustments are made based on daily warehouse temperature, humidity, and pest levels to more accurately estimate the remaining shelf life, allowing for timely and effective handling within that timeframe. This application addresses the issue of excessive near-expiry materials, i.e., the amount A of materials to be processed. 处理 The materials are offered as an employee benefit and can be redeemed by staff who voluntarily come to make up for missed shifts.

Furthermore, the benefits for staff who make up for missed shifts can increase their enthusiasm for making up for missed shifts. In addition, any unredeemed materials nearing their expiration date can be donated to social organizations or charities in need, which can not only improve the company's social image and reputation, but also expand the market and enhance customer loyalty.
