Description

Technical Field

[0001] The present application relates to the field of production management technology, and in particular to a factory production monitoring method, system, equipment and medium. Background Art

[0002] In today's rapidly developing manufacturing industry, factory production efficiency, quality, and product performance stability have become key elements of a company's core competitiveness. For factories, how to accurately monitor product performance in real time during the production process to ensure that products meet established quality standards is a critical issue that needs to be addressed.

[0003] Traditional factory production monitoring methods rely primarily on manual spot checks and post-production testing. Manual spot checks have significant limitations. Firstly, due to the limited number of samples, they cannot fully and accurately reflect the performance of the entire batch of products. This can lead to some products with performance issues entering subsequent production stages or the market, causing financial losses and reputational risks to the company. Secondly, manual spot checks are labor-intensive and time-consuming, resulting in low efficiency and failing to meet the demands of modern large-scale production.

[0004] Post-production testing is a performance test conducted after product production is completed. Although this method can discover performance problems with the product, the problematic product has already been produced at this time, and the production process cannot be adjusted and optimized in time. This not only causes a waste of raw materials and production resources, but may also delay product delivery time, affecting the company's production plan and market competitiveness. Summary of the Invention

[0005] One purpose of the present application is to provide a factory production monitoring method, system, equipment and medium, at least to solve the technical problem of low real-time performance of production monitoring.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] First embodiment

[0020] The first embodiment of the present application relates to a factory production monitoring method. Figure 1 As shown, the method may include the following steps:

[0021] S101, setting an administrator mode and a monitor mode, wherein the administrator mode is deployed on the management-end computer, and the monitor mode is deployed on the monitoring-end computer:

[0022] By separating management and monitoring responsibilities and deploying them on different computers, an efficient monitoring system with a collaborative approach is achieved. Administrator mode is deployed on the management computer, facilitating centralized management and decision-making; monitor mode is deployed on the monitoring computer (the production line computer), enabling real-time data collection and processing at the production site. This separation makes management and monitoring more professional, improving the reliability and maintainability of the entire monitoring system. For example, in a large factory, different production lines are located in different areas. With this setup, administrators can centrally monitor all production lines from the management side, while the monitoring side focuses on data collection and preliminary processing for each production line, avoiding management and monitoring confusion.

[0023] S102: The administrator mode authorizes modification of the monitoring terminal computer configuration, real-time viewing of CPK charts of all production lines, and setting of data statistics and alarm thresholds:

[0024] Administrators can flexibly adjust the configuration of the monitoring computer based on production needs and actual conditions. For example, if a production process changes, administrators can promptly modify the monitoring computer's parameter settings to ensure the monitoring system accurately reflects production conditions. This enhances the system's adaptability and flexibility, enabling rapid response to changes in the production process.

[0025] The CPK chart intuitively demonstrates the process capability and stability of a production line. Administrators can gain real-time insights into the production status of each production line and promptly identify potential quality issues. By analyzing the CPK chart, administrators can predict potential fluctuations in the production process and take proactive measures to adjust, effectively preventing product quality issues. For example, if the CPK value of a production line continues to decline, administrators can intervene promptly to check factors such as equipment operation status and raw material quality to prevent the mass production of substandard products.

[0026] The setting of data statistics determines the monitoring system's frequency of production data collection and the scope of its analysis. Properly setting data statistics can improve system efficiency while ensuring monitoring accuracy. The setting of alarm thresholds provides an early warning mechanism for the monitoring system. When the CPK value falls below the preset alarm threshold, the system can promptly issue an alarm, prompting the administrator to take action. For example, if the 1k monitoring statistic is collected once, the alarm threshold is 1.33; if the 2k monitoring statistic is collected once, the alarm threshold is 1.53. For production lines with higher product quality requirements, a lower alarm threshold can be set to more promptly detect quality issues; for production lines with relatively lower quality requirements, the alarm threshold can be appropriately increased to reduce unnecessary alarm interference.

[0027] S103: The monitor mode collects production data in real time, calculates the CPK value based on the production data, and generates the CPK chart for display:

[0028] By collecting production data in real time, the monitor mode can promptly obtain the actual operating status of the production line. This data forms the basis for the subsequent calculation of the CPK value and analysis of production process stability. The CPK value is an important indicator of production process capability, taking into account both the mean and fluctuation of the process. By calculating the CPK value and generating a CPK chart, the monitor can intuitively understand the production quality and stability of the production line. For example, a CPK value greater than 1.33 indicates sufficient production process capability and relatively stable product quality. A CPK value less than 1 indicates significant fluctuations in the production process, requiring timely adjustments. The display of the CPK chart enables the monitor to quickly identify anomalies in the production process, providing strong support for timely action.

[0029] S104: When the CPK value is lower than the preset alarm threshold, the monitoring computer issues a local alarm and reports the alarm information to the management computer:

[0030] Local alarm notifications on the monitoring computer allow on-site operators to promptly understand any problems that arise during production. This timely feedback prompts operators to take immediate action to prevent further problems. For example, when an audible or visual alarm sounds on the monitoring computer, operators can quickly check the equipment's operating status and identify possible causes of the problem.

[0031] Alarm information is reported to the management computer, allowing administrators to promptly monitor abnormalities on the production line. Based on these alarms, administrators can consider the overall situation of the production system and make more informed decisions. For example, based on the alarm information, administrators can determine whether to suspend the production line for maintenance or adjust production plans to minimize losses.

[0032] S105: After receiving the alarm information, the management computer pops up an alarm prompt box, and the administrator controls the start and stop of the production line according to the situation:

[0033] An alarm prompt box pops up on the management computer, alerting the administrator to abnormal conditions on the production line in a striking manner. The alarm prompt box can include detailed alarm information, such as the alarm production line number, CPK value, and alarm time, allowing the administrator to quickly understand the severity and specific circumstances of the problem.

[0034] Administrators have the power to control the start and stop of production lines based on alarm information and actual conditions. This provides effective safety assurance for the production process. For example, if a serious quality issue or equipment failure occurs on a production line, the administrator can promptly pause the line to prevent continued production of substandard products and further damage to the equipment. Once the problem is resolved, the administrator can restart the line and resume normal production. This flexible control mechanism improves the controllability and stability of the production process.

[0035] Second embodiment

[0036] The second embodiment of the present application relates to a factory production monitoring method. The second embodiment is an improvement based on the first embodiment, and the specific improvements are:

[0037] The management computer and the monitoring computer establish a connection with the database through a unique ID, and data upload and command issuance are both transferred through the database.

[0038] When each management and monitoring computer is deployed, it is assigned a unique ID to identify it within the system. During system operation, the monitoring computer collects production data and uploads it to the database's data storage table using its unique ID, following the specified format and protocol. When the management computer needs to issue instructions (such as changing configurations or controlling the start and stop of a production line), it also stores these instructions in the corresponding location in the database using its unique ID. The monitoring computer periodically reads the instructions corresponding to its own ID from the database.

[0039] This data transfer method enhances the system's scalability and flexibility. On the one hand, different computer devices can be easily connected to the system, simply by assigning a unique ID to communicate with the database. On the other hand, the database, as a centralized data storage and processing center, facilitates unified data management and maintenance, while also improving the reliability and security of data transmission.

[0040] The database includes an administrator information table, a management table, an operation record table, a data storage table, and a data CPK storage table.

[0041] The database includes: confirming the account type through the administrator information table to enter the administrator mode or monitor mode; recording the login status, data statistics and alarm thresholds of all computers through the management table; recording the application operation records, alarm records and administrator response records of all computers through the operation record table; recording the production data uploaded by the monitoring terminal computer through the data storage table; recording the CPK value and the local path of the CPK chart through the CPK storage table.

[0042] Administrator Information Table: This table is populated manually, allowing users to add only administrator accounts, avoiding unnecessary operations. It stores account information for all administrators and monitors, including account name, password, and account type (administrator or monitor). When a user logs in, the system verifies the entered account and password against the Administrator Information Table. If a match is successful, the user is directed to the corresponding administrator or monitor mode based on the account type. Centralized management of account information allows for effective control of system access rights, ensuring that only authorized users can enter the corresponding operating mode, thereby improving system security.

[0043] Management Table: This records information such as the login status, data statistics, and alarm thresholds for all computers. When a monitoring computer logs in to the system, it updates its login status to the management table. Administrators can modify data statistics and alarm thresholds in the management table from the management computer, and these changes are synchronized to the relevant monitoring computers in real time. This allows administrators to comprehensively manage and monitor the operating status of the entire system, allowing them to flexibly adjust data statistics and alarm parameters based on actual production conditions, improving system adaptability and management efficiency.

[0044] Operation Log: This table records all computer application operation records, alarm records, and administrator response records. When a monitoring computer submits an application to change information or an alarm occurs, the relevant information is stored in the operation log. When the administrator handles these applications or alarms, the administrator also records the response information in this table. This provides detailed audit records for system operation and management, allowing administrators to trace and analyze historical system operations, promptly identify and resolve potential issues, and provide data support for production process optimization.

[0045] Data Storage Table: Production data collected in real time by the monitoring computer is uploaded to the data storage table at specified intervals or data volume thresholds. The data storage table categorizes this data, for example, by production line number or product type, to facilitate subsequent data query and analysis. This enables centralized storage and management of production data, providing a rich data resource for subsequent data analysis and mining, helping to identify patterns and issues in the production process and providing strong support for production decision-making.

[0046] Data CPK Storage Table: After calculating the CPK value and generating the CPK chart, the monitoring computer stores the CPK value and the local path to the CPK chart in the data CPK storage table. The management computer can query this table to obtain CPK information for each production line and view the corresponding CPK chart. This allows administrators to monitor and evaluate the production process capabilities of each production line in real time, promptly identifying fluctuations and anomalies in the production process and providing a basis for adjustment and optimization.

[0047] Administrator mode includes: receiving CPK alarm information from the monitoring computer, popping up an alarm prompt box, confirming that the alarm information action is completed before the monitoring computer that issued the alarm information can continue to execute; locking the monitoring computer control and controlling the start and stop of the production line.

[0048] When the monitoring computer detects that the CPK value falls below the preset alarm threshold, it uploads the alarm information to the database's operation log table. The management computer monitors the operation log table in real time. Once a new alarm is detected, an alarm prompt box pops up, alerting the administrator of a production line anomaly. After viewing the alarm information, the administrator must confirm the operation. Once confirmed, the database updates the alarm status in the operation log table. The monitoring computer can only proceed with subsequent operations after detecting the updated alarm status. This ensures that administrators are promptly informed of abnormalities on the production line and can effectively address them, preventing production problems from escalating due to untimely alarm processing.

[0049] In certain situations, such as when a production line needs to be inspected or adjusted, an administrator can send a lock command from the management computer to the database. The database stores this command in a management table. Upon receiving the lock command, the monitoring computer will lock its own interface, prohibiting the operator from performing any related operations. Administrators can also send production line start and stop commands from the management computer to the database. The database forwards these commands to the corresponding monitoring computer, which then controls the production line accordingly. This enhances administrators' control over the production process, enabling them to take swift action when necessary to ensure safety and stability.

[0050] The monitor mode includes: viewing the CPK chart; submitting the information for applying for change to the management terminal computer; reporting the alarm information to the management terminal computer, and prompting the alarm information to be on the current monitoring terminal computer.

[0051] The monitor can log in to the system through the monitoring computer, query the CPK chart information of the current production line from the data CPK storage table in the database, and display it on the monitoring computer. The monitor can view the changes of the CPK chart in real time and understand the production process capability of the production line.

[0052] When a monitor discovers a need to change certain parameters (such as data statistics or alarm thresholds) during the production process, they can submit a request for change to the database's operation log table via the monitoring computer. The management computer regularly reviews the request information in the operation log table and approves it. This gives the monitor a degree of independent decision-making power, allowing them to submit parameter change requests in a timely manner based on actual production conditions, thereby improving the flexibility and adaptability of the production process.

[0053] When the CPK value calculated by the monitoring computer falls below the preset alarm threshold, an alarm message is uploaded to the database's operation log table, and a local alarm prompt (such as audible and visual alarms, pop-up window prompts, etc.) is issued on the monitoring computer. This ensures that the monitor can promptly understand abnormal conditions on the local production line, and the alarm information is promptly reported to the management computer so that the administrator can take appropriate measures.

[0054] Calculating the CPK value includes: the calculation formula is CPK=min[(USL-μ) / (3σ),(μ-LSL) / (3σ)]; where USL is the upper specification limit; LSL is the lower specification limit; μ is the process mean; and σ is the standard deviation.

[0055] After collecting production data, the monitoring computer performs statistical analysis and calculates the process mean μ and standard deviation σ. Furthermore, the upper specification limit (USL) and lower specification limit (LSL) for product performance indicators are pre-set based on production process requirements. The CPK value is then calculated using the aforementioned formula and stored in the database's data CPK storage table.

[0056] like Figure 2 and Figure 3 As shown, sample information: A total of 2246 samples (Samples) were collected, with a mean value (MeanValue) of 52.31, a minimum value (MinValue) of 13.00, and a maximum value (MaxValue) of 64.00. Specification limits: The lower specification limit (LSL) is 10.00, the upper specification limit (USL) is 100.00, and the acceptable range for this test item is 10.00-100.00. Process capability indicators: The standard deviation (STDEV) is 7.747435, the process capability index (CP) is 2.01, and the process performance index (Cpk) is 1.89. Both CP and Cpk are greater than 1.33, indicating good process capability and relatively stable product quality. However, Cpk is less than CP, indicating that the process mean (52.31) deviates from the center of the specification and is closer to the LSL. Figure 2 The frequency distribution indicates that the data are concentrated within a certain range, with some areas having higher frequencies. However, a small amount of data is close to LSL, so attention should be paid to whether there is potential fluctuation. Figure 3 The data trend indicates that the data changes with the sample, and the overall fluctuation is between LSL and USL. Most of the data are far away from USL, and some points are close to LSL but not lower than LSL. However, these points close to LSL still need to be monitored to prevent them from exceeding the specification limit in the future.

[0057] Overall, the current production process capability is acceptable, but attention needs to be paid to mean shift and data points approaching LSL to ensure production stability and product quality. The CPK chart generated by a specific project during production testing clearly illustrates product performance trends. Timely alerts enable more accurate adjustments, thereby optimizing and improving product performance and quality consistency. By calculating CPK values in real time, monitors and administrators can promptly identify potential issues in the production process and take appropriate measures to adjust and optimize, thereby improving product quality and production efficiency.

[0058] The step division of the above various methods is only for the purpose of clear description. During implementation, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this application; adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the scope of protection of this application.
