Description

Technical Field

[0001] The present invention relates to the technical field of mold temperature control, and in particular to a one-stop mold temperature monitoring and control method. Background Art

[0002] In order to improve the production capacity and body quality of automobile companies, the tonnage of die-casting machines used in body-integrated die-casting technology is getting larger and larger, and the size of molds is getting larger and larger, but it also makes mold temperature control more and more difficult. The quality of mold temperature control directly affects the quality of the product. Process engineers are often faced with the control of hundreds of pipeline parameters.

[0003] With the continuous development of digital technology, the industry has developed a variety of mold temperature monitoring and control systems: For the mold temperature control system, the purpose of mold temperature control is achieved by controlling the temperature control equipment connected to the internal passage of the mold. The system is mainly used to monitor and control the operating status of equipment around the die-casting machine, such as water temperature machine, oil temperature machine, vacuum machine, etc., so that engineers do not need to interact directly with the temperature control equipment unit, but only need to remotely and uniformly control it through the centralized control system, which simplifies the manual control process; For the mold temperature monitoring system, multiple infrared cameras are integrated, and the temperature of the mold surface is monitored in real time with the help of infrared thermal imaging technology. The real-time temperature of each position in the camera's shooting picture is displayed in the system, so as to monitor the mold temperature. By evaluating the mold temperature at key time points in each die-casting cycle, it is determined how to adjust the parameters of the temperature control equipment in the next step to ensure the quality of the die-casting products. The system improves the accuracy, safety and convenience of mold temperature monitoring. However, in actual industrial scenarios, most products often use independent centralized control systems and mold temperature monitoring systems. The two systems run simultaneously. Engineers use the mold temperature monitoring system to observe whether the mold temperature is abnormal, and then find the equipment pipeline corresponding to the abnormal mold temperature location, and then find the corresponding pipeline in the centralized control system to set the pipeline parameters to achieve mold temperature control. However, this mold temperature control solution still requires engineers to manually trace the abnormal mold temperature location and the corresponding pipeline, and then switch to the centralized control system page to set the equipment pipeline parameters. This solution still requires a lot of expensive manual operation costs.

[0047] According to the preset alarm temperature threshold, it is determined whether the temperature of each key temperature measurement feature point exceeds the set range, and an alarm signal is issued based on exceeding the set range.

[0048] Compared with the prior art, the beneficial effects of the present invention are that, by integrating mold temperature monitoring and control into a system page, the operation process is simplified and work efficiency is improved. Through the visual display of mold diagrams and thermal imaging data, engineers can more intuitively understand the mold temperature field distribution, which is convenient for analysis and adjustment. The automatic monitoring and alarm function can timely detect mold temperature anomalies and avoid product defects. The high degree of automation reduces manual operations and labor costs. It can timely detect and adjust temperature anomalies, reduce scrap rate, reduce material costs, accurately control mold temperature, extend mold life, reduce mold replacement costs, accurately control mold temperature, ensure product quality stability, collect and analyze mold temperature data, provide data support for process optimization and improvement, and realize intelligent control of mold temperature based on data analysis to improve production efficiency and product quality.

[0049] By drawing and naming pipelines, the tedious process of manual marking and recording is avoided, and efficiency and accuracy are improved. The target mold diagram clearly shows the pipeline layout inside the mold, which is convenient for temperature monitoring and control. When the mold or pipeline changes, the target mold diagram can be easily modified without redrawing. The automated pipeline drawing and naming function reduces manual operations and reduces labor costs, avoids possible errors in the manual marking and recording process, and reduces the scrap rate. Through the association mapping of the target mold diagram and the actual temperature control equipment, precise control of the mold temperature is achieved, ensuring the stability of product quality. The temperature changes can be intuitively observed through the target mold diagram, problems can be discovered and adjusted in time, and product defects can be reduced. The target mold diagram and pipeline information provide a data basis for mold temperature control, provide data support for process optimization and improvement, and provide an accurate and reliable data basis for mold temperature control, which improves work efficiency and accuracy, reduces costs, improves product quality, and promotes the industrial digital transformation of the die-casting industry.

[0050] By storing pipeline information in the form of functions, the target mold diagram pipeline channel and the actual temperature control equipment pipeline are automatically matched, which improves efficiency and accuracy. Temperature control is performed based on the pipeline function expression, which realizes precise control of mold temperature and ensures the stability of product quality. When the mold or pipeline changes, the function expression can be easily modified without redrawing the pipeline, which improves the scalability of the system. The automated matching and binding functions reduce manual operations and labor costs, avoid errors that may occur during manual matching and binding, and reduce scrap rates. By storing pipeline information in the form of functions, precise control of mold temperature is achieved and the stability of product quality is ensured. The coordinates of any point on the pipeline can be quickly calculated through the function expression, which is convenient for temperature monitoring and analysis, timely detection of problems and adjustments, and reduction of product defects.

[0051] Through secondary association mapping, the temperature measurement characteristic parameters in the actual infrared thermal image are accurately mapped to the target mold map, which improves the accuracy of temperature monitoring. The image correction algorithm is applied in the mapping process to ensure the accurate correspondence between the infrared thermal image and the mold map, reducing the measurement error. The visualization of the mold temperature field is achieved by mapping the center point of the grid microelement to the mold front view and performing temperature rendering. By directly displaying the temperature of the temperature measurement point on the mold map, the temperature abnormality area can be quickly and intuitively identified. By manually drawing the mold contour map and calculating the proportion, the mapping process from thermal imaging to the mold map is simplified, and the convenience of operation is improved. The grid division and temperature field rendering are automatically completed, which reduces manual intervention and improves work efficiency. Real-time temperature field rendering provides instant temperature feedback, which is convenient for timely adjustment of temperature control parameters and reduces temperature fluctuations in the production process. The data generated by secondary association mapping provides a basis for intelligent production, which helps to achieve more advanced automation and intelligent control. By integrating infrared thermal imaging technology and mold map mapping, the pace of digital transformation in the die-casting industry has been promoted.

[0052] Through the target circle with a fixed length as the radius, the final temperature measurement feature point and the final pipeline channel are accurately judged and bound, ensuring the accuracy of the monitoring data. The binding operation is performed through mathematical formulas and geometric relationships, reducing human judgment errors and improving the degree of automation. The binding operation is performed one by one on each final temperature measurement feature point to ensure that the monitoring system fully covers the mold temperature. The results of the binding operation can be fed back to the monitoring system in real time to facilitate timely adjustment of the temperature control strategy. The preset fixed length and target circle simplify the binding process and improve operational efficiency. The intelligent judgment of whether to perform the binding operation is based on the positional relationship between the target circle and the pipeline, reducing human intervention and improving the intelligence level of the process. The rapid completion of the binding operation enables the mold temperature anomaly to be quickly identified and processed, thereby improving production efficiency.

[0053] By clicking on the target mold image, the corresponding temperature measurement characteristic parameters can be obtained, which greatly improves the interactivity. The distance between the target click position and each final temperature measurement characteristic point can be quickly calculated, and the target temperature measurement characteristic point can be quickly located. By comparing the actual distance and the standard distance threshold, the temperature measurement characteristic points that are close enough to the target click position can be accurately screened out to ensure the accuracy of the data. The use of standardized distance measurement methods reduces human judgment errors and improves the automation and intelligence level of the system. The preset standard distance threshold simplifies the screening process of temperature measurement characteristic points and improves operational efficiency. The temperature measurement characteristic parameter set corresponding to the target click position can be fed back in real time, which is convenient for timely adjustment of the temperature control strategy and rapid response capability, so that mold temperature anomalies can be quickly identified and processed, thereby improving the overall efficiency of the production line. Accurate temperature measurement characteristic point screening helps prevent mold temperature anomalies, thereby reducing maintenance costs and downtime.

[0054] By comparing historical and real-time monitoring data, it is possible to promptly discover temperature change trends, prevent potential mold temperature anomalies, ensure product quality, make corresponding adjustments based on temperature change trends, optimize mold temperature control strategies, and improve control accuracy. When the temperature of key temperature measurement feature points exceeds the preset range, an alarm signal can be issued in real time, improving emergency response capabilities. The automated alarm mechanism reduces possible negligence in human monitoring and improves production safety. By analyzing historical and real-time data, data support is provided for continuous improvement of the production process. By monitoring temperature change trends, potential problems can be predicted, so that measures can be taken in advance to avoid production interruptions. Timely adjustments and alarms reduce downtime caused by temperature anomalies, improve production efficiency, ensure the stability of mold temperature, and ensure the continuity and stability of the production process. Through monitoring and adjustment, preventive maintenance is achieved and the maintenance cost of the mold is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The present invention provides a one-stop mold temperature monitoring and control method, comprising:

[0064] Step S100, determining an initial mold diagram, and sequentially drawing and naming target pipelines on the initial mold diagram to obtain a target mold diagram;

[0069] Step S600, adjusting the key temperature measurement characteristic parameters accordingly or issuing an alarm according to the real-time monitoring results combined with historical monitoring results.

[0070] Specifically, this embodiment discloses a one-stop mold temperature monitoring and control method, which solves the problem that temperature monitoring and temperature control in the vehicle body integrated die-casting scenario are difficult to integrate and collaborate in one system page, and mainly includes the following three processes:

[0071] 1. "Mapping of mold diagram and temperature control pipeline": import the 3D mold diagram (or 2D mold diagram in picture format) with the internal pipeline channel of the mold into the mold temperature control system software, and then automatically map the 3D mold diagram to the front view of the 2D plane of the mold, and map the internal pipeline channel of the mold in the form of lines and dots at the corresponding position of the front view, and display the corresponding channel name, and finally associate and map the pipeline name of the actual temperature control equipment with the corresponding internal pipeline channel of the mold;

[0072] 2. "Mapping of mold image and thermal image taken by thermal imaging": set key temperature measurement feature points or areas, such as gate position, diverter cone position, etc., according to the actual two-dimensional real-time mold temperature monitoring screen in the thermal imaging device, and then map the temperature measurement feature points or areas in the real-time screen to the corresponding positions of the two-dimensional front view of the mold, and display the real-time temperature information;

[0073] 3. "Mapping of temperature measurement position and equipment pipelines". Click any mold position and the system will automatically find the nearest temperature measurement point. The system will automatically map it to the control pipeline of the temperature measurement feature point or regional temperature, that is, search or pre-bind several pipelines closest to the feature point or region (the distance between the pipeline and the temperature measurement position is less than a certain threshold), and map them to the real equipment pipelines, displaying the real-time information of these pipelines. At the same time, it supports setting the parameters of these equipment pipelines, thus truly realizing one-stop integrated operation of mold temperature monitoring and control.

[0074] The one-stop mold temperature control method in the present invention respectively realizes the one-stop operation of mold temperature monitoring and control in one system page through "mapping of mold diagram and temperature control pipeline", "mapping of mold diagram and thermal imaging thermal map" and "mapping of temperature measurement position and equipment pipeline", and can adapt to all die-casting and similar scenarios, greatly reducing the time and cost of tracing mold temperature abnormalities, greatly simplifying the process of mold temperature control and the difficulty of actual operation, and achieving the effects of fast feedback, fast tracking and fast adjustment, which can ultimately reduce costs and increase efficiency for enterprises, improve the qualified rate of die-casting products and the life of die-casting molds, and realize industrial digital transformation.

[0075] Specifically, the embodiment of the present invention simplifies the operation process and improves work efficiency by integrating mold temperature monitoring and control into a system page. Through the visual display of mold diagrams and thermal imaging data, it helps engineers to understand the mold temperature field distribution more intuitively, facilitates analysis and adjustment, and has automatic monitoring and alarm functions to timely detect mold temperature anomalies and avoid product defects. It has a high degree of automation, reduces manual operations, reduces labor costs, timely detects and adjusts temperature anomalies, reduces scrap rate, reduces material costs, accurately controls mold temperature, extends mold life, reduces mold replacement costs, accurately controls mold temperature, ensures the stability of product quality, collects and analyzes mold temperature data, provides data support for process optimization and improvement, and realizes intelligent control of mold temperature based on data analysis to improve production efficiency and product quality.

[0076] Specifically, in this embodiment, the process of determining the initial mold image includes:

[0077] Step S111, obtaining an initial mold file with internal pipeline channels of the mold;

[0078] Step S112, determining to start the screenshot mode according to the actual type of the initial mold file, or directly generating the initial mold image;

[0079] Among them, based on the fact that the actual type is a three-dimensional mold file, it is determined to open the screenshot mode and obtain the initial mold image based on the screenshot mode; based on the fact that the actual type is a two-dimensional mold file, the initial mold image is directly generated.

[0080] Specifically, in the specific implementation process, a three-dimensional mold drawing file is imported or a two-dimensional mold front view is directly imported. If a three-dimensional mold drawing file is imported, the front view of the three-dimensional mold is first captured to obtain the two-dimensional front view of the mold. If a two-dimensional mold drawing is imported, this step is omitted.

[0081] Specifically, in this embodiment, the process of sequentially drawing target pipelines and naming target pipelines on the initial mold diagram to obtain the target mold diagram includes:

[0082] Step S121, according to different types of target pipelines, different drawing symbols are selected to draw the target pipelines to obtain the target pipeline layout;

[0083] Step S122, based on the target pipeline layout, record the relative position with the initial mold diagram, and name the target pipeline according to the relative position to obtain the target mold diagram.

[0084] Specifically, in the specific implementation process, straight lines, broken lines or dots are added and edited on the target mold diagram to represent the pipeline layout inside the mold, and the position of each pipeline relative to the mold is recorded to name each pipeline, obtain the pipeline information of each actual temperature control device, and bind the pipelines of each actual temperature control device to the pipelines drawn on the target mold diagram, thereby realizing an association mapping between the target mold diagram and each actual temperature control device.

[0085] Specifically, the embodiment of the present invention avoids the tedious process of manual marking and recording by drawing and naming pipelines, thereby improving efficiency and accuracy. The target mold diagram clearly displays the pipeline layout inside the mold, which is convenient for temperature monitoring and control. When the mold or pipeline changes, the target mold diagram can be easily modified without redrawing. The automated pipeline drawing and naming functions reduce manual operations and labor costs, avoid errors that may occur in the manual marking and recording process, and reduce the scrap rate. Through the association mapping of the target mold diagram and the actual temperature control equipment, precise control of the mold temperature is achieved, and the stability of product quality is ensured. The temperature changes can be intuitively observed through the target mold diagram, problems can be discovered and adjusted in time, and product defects can be reduced. The target mold diagram and pipeline information provide a data basis for mold temperature control, provide data support for process optimization and improvement, and provide an accurate and reliable data basis for mold temperature control, thereby improving work efficiency and accuracy, reducing costs, improving product quality, and promoting the industrial digital transformation of the die-casting industry.

[0086] See also Figure 2 As shown, it is a flowchart of an association mapping in a one-stop mold temperature monitoring and control method according to an embodiment of the present invention, wherein the process of associating and mapping the target pipeline channel corresponding to the target mold diagram and the actual pipeline name corresponding to each actual temperature control device based on the actual pipeline information includes:

[0087] Step S210, storing the target pipeline channel in a function form to obtain actual storage information;

[0088] Step S220, importing a configuration file containing the actual pipeline information, reading the configuration file, and obtaining a unique pipeline identifier of each actual temperature control device;

[0089] Step S230: Binding each unique pipeline identifier with the actual storage information.

[0090] Specifically, in this embodiment, the process of storing the target pipeline channel in the form of a function to obtain actual storage information includes:

[0091] Step S211, constructing a target coordinate system, and obtaining an objective function expression of the target pipeline channel based on the target coordinate system;

[0092] Step S212, the process of constructing the target coordinate system is to use the target area where the target mold image is located as the coordinate axis, and the lower left corner of the target area as the coordinate origin;

[0093] Wherein, when the target pipeline channel is a broken line, the corresponding broken line pipeline channel is stored as a set of straight line function expressions of all straight line pipeline channels constituting the broken line pipeline channel.

[0094] In the specific implementation process, a configuration file is pre-set, which contains the pipeline information of all temperature control devices, such as device name, pipeline number, and pipeline type. Through the file reading operation, the information in the configuration file is loaded into the memory for subsequent use. The configuration file records the relationship between each device identifier and its corresponding pipeline, such as "device A, pipeline 1", "device B, pipeline 2". By parsing the configuration file, the unique identifier of each device and its corresponding pipeline information are extracted. For example, the device identifier of a water temperature machine is "WS-001", and there are two pipelines inside it, numbered "A" and "B" respectively. In the configuration file, the information of these two pipelines can be recorded as: "WS-001, A", "WS-001, B",

[0095] The pipeline information drawn on the target mold diagram is matched with the pipeline information read from the configuration file. The matching process is performed according to the pipeline name or pipeline number. For example, the pipeline "M1" on the target mold diagram is matched with "WS-001, A" in the configuration file. After the match is successful, the two are bound to establish an association relationship between the pipeline channel of the target mold diagram and the pipeline of the actual temperature control equipment. For example, assuming that a pipeline named "M1" is drawn on the target mold diagram, according to step S220, the pipeline information is stored as a function expression, such as "y = x + 1", in the configuration file, the pipeline information of "WS-001, A" is read, and by matching "M1" and "A", the two are bound to establish an association relationship between the "M1" pipeline channel on the target mold diagram and the "A" pipeline on the water temperature machine "WS-001". When the pipeline on the target mold diagram is a broken line, the broken line is decomposed into several straight line segments, and each straight line segment is stored as an independent straight line function expression according to step S211. The collection of all straight line function expressions constitutes a complete function expression of the broken line pipeline.

[0096] Specifically, the embodiment of the present invention stores pipeline information in the form of functions, realizes automatic matching of the pipeline channel of the target mold diagram with the pipeline of the actual temperature control equipment, improves efficiency and accuracy, performs temperature control based on the pipeline function expression, realizes precise control of the mold temperature, and ensures the stability of product quality. When the mold or pipeline changes, the function expression can be easily modified without redrawing the pipeline, thereby improving the scalability of the system. The automated matching and binding functions reduce manual operations and labor costs, avoids possible errors in manual matching and binding, and reduces the scrap rate. By storing pipeline information in the form of functions, precise control of the mold temperature is realized, and the stability of product quality is ensured. The coordinates of any point on the pipeline can be quickly calculated through the function expression, which is convenient for temperature monitoring and analysis, and problems can be discovered and adjusted in time to reduce product defects.

[0097] See also Figure 3 As shown, it is a flow chart of secondary association mapping in the one-stop mold temperature monitoring and control method according to an embodiment of the present invention, wherein the key temperature measurement characteristic parameters are set, the actual temperature measurement characteristic parameters in the real-time screen are obtained based on the key temperature measurement characteristic parameters, and the process of secondary association mapping between the actual temperature measurement characteristic parameters and the target mold map includes:

[0098] Step S310, obtaining the actual infrared thermal images corresponding to each key temperature measurement position of the target object to obtain actual temperature measurement characteristic parameters;

[0099] Step S320, determining a target contour of the target mold image, and determining an actual ratio of the actual temperature measurement characteristic parameter to the target contour;

[0100] Step S330: performing secondary association mapping on the actual temperature measurement characteristic parameters and the target mold image according to the actual ratio.

[0101] Specifically, in this embodiment, the process of performing secondary association mapping between the actual temperature measurement characteristic parameter and the target mold image according to the actual ratio includes:

[0102] The temperature measurement points corresponding to the actual infrared thermal image are drawn in the target mold image based on the actual ratio, and the actual infrared thermal image is corrected according to an image correction algorithm during the drawing process.

[0103] In this embodiment, temperature measurement points are drawn in the infrared thermal imaging system, and then the temperature measurement feature points or areas are mapped to the front view of the mold. If the temperature measurement feature is a geometric area, the center of the geometric area is used. At this point, the mapping of the mold temperature measurement feature is completed. According to the mapping principle, the mold thermal map can be divided into multiple grid elements, and the center points of the grid elements are used to map to the front view of the mold, and the small area is rendered with the temperature of the center point, thereby completing the temperature field rendering of the mold image, and finally realizing the mapping of the thermal image taken by thermal imaging to the mold image.

[0104] In the specific implementation process, the specific process of secondary association mapping is as follows:

[0105] 1) Manually draw the mold outline in the thermal image taken by the infrared camera. The border is a parallelogram mold frame line composed of four straight line segments. The four mold frame line segments are saved as equation expressions of four corresponding straight lines. , , the calculated side lengths of the parallelogram mold borders in the heat map are , the side lengths of the parallelogram mold frame in the mold front view are ;

[0107] 2) Take a certain temperature measurement feature point Take the temperature feature point in the camera thermal image as an example and calculate the distance between the two adjacent mold border lines. and , calculate the ratio of each distance to the mold frame line parallel to the direction, determine the position of the temperature measurement feature point in the mold front view according to the ratio, and realize the mapping of the mold image and the thermal image taken by thermal imaging. It can be obtained by formula 1 and formula 2, and The distance from the point to the line is calculated, assuming that the left line The equation is , then the point Distance to straight line The calculation is shown in formula 3, Similarly, according to The coordinates of the mapping point in the mold front view can be determined and the temperature measurement point can be drawn.

[0109] 3) The part within the frame of the infrared thermal image is gridded, and the center point of each grid element is mapped to the front view of the mold. The temperature in each grid element can be roughly considered to be the same, so as to render the mold temperature field of the entire mold image.

[0110] Specifically, the embodiment of the present invention accurately maps the temperature measurement characteristic parameters in the actual infrared thermal image to the target mold image through secondary association mapping, thereby improving the accuracy of temperature monitoring. The image correction algorithm is applied in the mapping process to ensure the accurate correspondence between the infrared thermal image and the mold image, reducing the measurement error. The visualization of the mold temperature field is achieved by mapping the center point of the grid microelement to the mold front view and performing temperature rendering. By directly displaying the temperature of the temperature measurement point on the mold image, the temperature abnormality area can be quickly and intuitively identified. By manually drawing the mold contour map and calculating the proportion, the mapping process from thermal imaging to the mold image is simplified, the convenience of operation is improved, the grid division and temperature field rendering are automatically completed, manual intervention is reduced, and work efficiency is improved. The real-time temperature field rendering provides instant temperature feedback, which is convenient for timely adjustment of temperature control parameters and reduces temperature fluctuations in the production process.

[0111] See also Figure 4 As shown, it is a flowchart of the actual binding in the one-stop mold temperature monitoring and control method according to an embodiment of the present invention, wherein the process of binding the final pipeline channel after the primary association mapping and the final temperature measurement characteristic parameter after the secondary association mapping to obtain the actual binding result includes:

[0112] Step S410, performing a binding operation on each final temperature measurement feature point one by one;

[0113] Step S420, for any final temperature measurement feature point, taking the final temperature measurement feature point as the center of the circle and a preset fixed length as the radius, to form a target circle;

[0114] Step S430, determining whether to perform the binding operation according to the positional relationship between the target circle and each final pipeline channel;

[0115] Step S440, determining to perform the binding operation based on the positional relationship between the target circle and any final pipeline channel being an intersection;

[0116] Wherein, the final temperature measurement characteristic parameters include a number of final temperature measurement characteristic points.

[0117] In the specific implementation process, the specific process of the binding operation is as follows:

[0118] 1) Record the geometric coordinates of the final temperature measurement feature point as , set the influence radius to , save the influence range function of the temperature measurement feature, the range is is the center of the circle, is a circle with a radius of 1, the rectangular area where the mold image is located is the coordinate axis, and the lower left corner is the coordinate origin;

[0119] 2) Each straight line segment or broken line segment pipeline corresponds to one or more straight line equation expressions , and record the endpoints of the line segment and , the dot pipeline is saved as a coordinate ;

[0120] 3) Determine whether each line segment intersects with the circle. If so, it means that the pipeline has a significant impact on the feature point and needs to be bound. For example, first determine whether the two endpoints of the line segment are in the circle. If at least one of them is in the circle, bind the temperature measurement feature to the pipeline and directly calculate whether the distance from each endpoint to the center of the circle is less than the radius. If so, it is in the circle. If neither of the two endpoints is in the circle, it is necessary to determine the distance from the center of the circle to the line segment. Is it greater than the radius? , the judgment method is as in formula 5. If it is greater than, they do not intersect and do not need to be bound. If the distance is less than the radius, it is necessary to further judge the two angles with the line segment as the endpoints. and Whether they are all acute angles can be calculated by the cosine formula and , if the cosine value is greater than 0, it indicates an obtuse angle, and if it is less than 0, it indicates an acute angle. First, calculate the two angles and The adjacent edge vector of is as shown in Formula 6, , and then calculate the cosine value of the vector angle. The formula for calculating the cosine value is Formula 7. The judgment method is as shown in Formula 8. If both are acute angles, the line segment and the circle intersect and need to be bound. If one is an obtuse angle, they do not intersect and do not need to be bound.

[0121]

[0122] 4) Complete the binding of all mold temperature measurement feature points and mold pipelines.

[0123] Specifically, the embodiment of the present invention uses a target circle with a fixed length as the radius to accurately judge and bind the final temperature measurement feature point and the final pipeline channel, thereby ensuring the accuracy of the monitoring data. The binding operation is performed through mathematical formulas and geometric relationships, which reduces human judgment errors and improves the degree of automation. The binding operation is performed one by one on each final temperature measurement feature point to ensure that the monitoring system fully covers the mold temperature. The results of the binding operation can be fed back to the monitoring system in real time to facilitate timely adjustment of the temperature control strategy. The preset fixed length and target circle simplify the binding process and improve operating efficiency. Whether to perform the binding operation is intelligently judged based on the positional relationship between the target circle and the pipeline, which reduces human intervention and improves the intelligence level of the process. The rapid completion of the binding operation enables mold temperature anomalies to be quickly identified and processed, thereby improving production efficiency.

[0124] Specifically, in this embodiment, the process of obtaining a target temperature measurement characteristic parameter set corresponding to each target click position according to the actual binding result includes:

[0125] Step S510, for any target click position, obtaining the actual distance between the target click position and each final temperature measurement feature point;

[0126] Step S510, determining each target temperature measurement feature point according to the actual distance combined with a preset standard distance;

[0127] Among them, based on the fact that the actual distance is less than or equal to the standard distance, it is determined as the target temperature measurement feature point.

[0128] In the specific implementation process, click any position on the target mold image, record the coordinate information of the position, and calculate the distance between the target click position and all the final temperature measurement feature points. In this embodiment, the distance calculation method can use the Euclidean distance formula or other distance measurement methods. This embodiment does not make specific limitations. A standard distance threshold is preset to determine whether the distance between the target click position and the temperature measurement feature point is close enough. The calculated distance is compared with the standard distance, and the temperature measurement feature points with a distance less than or equal to the standard distance are screened out. The screened temperature measurement feature points constitute a target temperature measurement feature parameter set corresponding to the target click position.

[0129] Specifically, the embodiment of the present invention can obtain the corresponding temperature measurement characteristic parameters by clicking on the target mold image, which greatly improves the interactivity, quickly calculates the distance between the target click position and each final temperature measurement characteristic point, and realizes the rapid positioning of the target temperature measurement characteristic point. By comparing the actual distance and the standard distance threshold, the temperature measurement characteristic points that are close enough to the target click position are accurately screened out, ensuring the accuracy of the data. The use of standardized distance measurement methods reduces human judgment errors and improves the automation and intelligence level of the system. Through the preset standard distance threshold, the screening process of temperature measurement characteristic points is simplified, and the operating efficiency is improved. The temperature measurement characteristic parameter set corresponding to the target click position can be fed back in real time, which is convenient for timely adjustment of the temperature control strategy and the rapid response capability, so that the mold temperature anomaly can be quickly identified and processed, thereby improving the overall efficiency of the production line. Accurate temperature measurement characteristic point screening helps prevent mold temperature anomalies, thereby reducing maintenance costs and downtime.

[0130] Specifically, in this embodiment, the process of adjusting the key temperature measurement characteristic parameters accordingly or issuing an alarm according to the real-time monitoring results combined with the historical monitoring results includes:

[0131] Step S610, obtaining the historical key mold temperatures of each key temperature measurement position in the historical mold;

[0132] Step S620, comparing the historical key mold temperature with the real-time monitoring result to determine the temperature change trend of each key temperature measurement feature point, and judging whether there is a temperature anomaly according to the temperature change trend, and making corresponding adjustments based on the existence of the temperature anomaly;

[0133] Step S630, judging whether the temperature of each key temperature measurement feature point exceeds a set range according to a preset alarm temperature threshold, and issuing an alarm signal if the temperature exceeds the set range.

[0134] In the specific implementation process, the historical key mold temperature data of each key temperature measurement position in the historical mold is obtained, such as the temperature records at key moments such as "before picking up the parts", "before spraying", and "after spraying". The historical key mold temperature data is compared and analyzed with the real-time monitoring results of the current mold, such as drawing a temperature trend graph, calculating the temperature difference, etc., observing the temperature change trend with the mold, such as judging whether the temperature rises, falls or remains stable, comparing the temperature differences between different molds, such as judging whether there is abnormal temperature fluctuation, analyzing the temperature fluctuation range, such as judging whether there is a situation where the temperature fluctuation is too large, if there is a temperature abnormality, entering the adjustment or alarm process; if the temperature is normal, continue to monitor, and according to the specific situation of the temperature abnormality, determine the key temperature measurement characteristic parameters that need to be adjusted, such as the target temperature, the alarm temperature, etc., automatically adjust the key temperature measurement characteristic parameters, such as modifying the target temperature, adjusting the alarm temperature threshold, and by adjusting the key temperature measurement characteristic parameters, the mold temperature is restored to normal to ensure product quality. According to the preset alarm temperature threshold, it is judged whether the temperature of each key temperature measurement characteristic point exceeds the set range. If the temperature exceeds the threshold, the alarm mechanism is triggered, such as sounding an alarm and displaying an alarm message.

[0135] Specifically, the embodiments of the present invention can timely discover temperature change trends, prevent potential mold temperature anomalies, ensure product quality, make corresponding adjustments according to temperature change trends, optimize mold temperature control strategies, and improve control accuracy. When the temperature of key temperature measurement feature points exceeds a preset range, an alarm signal can be issued in real time, thereby improving emergency response capabilities. The automated alarm mechanism reduces possible negligence in human monitoring and improves production safety. By analyzing historical and real-time data, data support is provided for continuous improvement of the production process. By monitoring temperature change trends, potential problems can be predicted, thereby taking measures in advance to avoid production interruptions. Timely adjustments and alarms reduce downtime caused by temperature anomalies, improve production efficiency, ensure the stability of mold temperature, and ensure the continuity and stability of the production process. Preventive maintenance is achieved through monitoring and adjustment, thereby reducing the maintenance cost of the mold.

[0136] The calculation compensation parameters and the calculation adjustment parameters described in the present invention have two functions: one is to balance the left and right dimensions of the formula, and the other is to adjust the numerical results. No specific assignment is performed in this embodiment. In addition, the calculation formulas in this embodiment are used to intuitively reflect the adjustment relationship between the numerical values, such as positive correlation and negative correlation. Unless otherwise specified, the parameter values ​​that are not specifically limited to numerical values ​​are all positive.
