Description

Technical Field

[0001] This invention relates to the field of mold production management technology, and in particular to a method, system and storage medium for mold management in molded product production. Background Technology

[0002] In the traditional mold production management process, QR code identification is usually used to record and query mold information.

[0003] However, this method has significant limitations: as a one-way, passive information identifier, the QR code only stores fixed static information (such as the mold number). It lacks data collection and processing capabilities, cannot sense or collect the mold's operating status in real time, and has no ability to actively report status data. This leads to a lag in data updates in the management system, affecting the efficiency of mold management.

[0004] In summary, existing technologies have low management efficiency and cannot meet the needs of real-time and efficient mold management. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a method for mold management in molded product manufacturing, which includes the following steps: Acquire mold status signals, the mold status signals including timing signals representing mold opening and closing actions; Based on the frequency characteristics and duration of the mold status signal, the current state of the mold is determined, including production state, trial mold state, maintenance state, and idle state. After the mold is used, or after the mold is used and a preset time has elapsed, the number of times the mold opens and closes is counted based on a timing signal to generate mold count data. The status and number of mold cycles are associated with the unique identifier of the mold and stored, and a mold usage history is generated.

[0006] Optionally, the current state of the mold is determined based on the frequency characteristics and duration of the mold state signal, specifically including: When the mold status signal exhibits a periodic change at a constant frequency and the duration is greater than or equal to a first duration threshold, the mold is determined to be in production status. When the mold status signal exhibits a non-constant frequency change and the duration is greater than or equal to the second duration threshold, the mold is determined to be in the trial molding state. When the mold status signal remains at a static signal value indicating that the mold is open, and the duration is greater than or equal to the third duration threshold, the mold is determined to be in maintenance status. When the mold status signal remains at a static signal value indicating mold closure for an extended period of time greater than or equal to the fourth duration threshold, the mold is determined to be in an idle state.

[0007] Optional, also includes: Upon receiving and in accordance with the mold search instruction, an activation signal is sent to the target mold to trigger a positioning prompt signal; the mold search instruction includes at least a unique identifier of the target mold; the positioning prompt signal includes at least an audible prompt signal and a visual prompt signal.

[0008] Optional, also includes: The system detects the distance between the user and the target mold and dynamically adjusts the sound and / or light prompts based on the distance.

[0009] Optionally, the sound prompt signal can be dynamically adjusted according to the distance, specifically: when the distance between the user and the target mold is less than a first distance threshold, the intensity of the sound prompt signal can be increased, the repetition frequency of the sound prompt signal can be increased, or the pitch of the sound prompt signal can be changed; The light prompt signal is dynamically adjusted according to the distance. Specifically, when the distance between the user and the target mold is less than a first distance threshold, the brightness of the light prompt signal is increased, the flashing frequency of the light prompt signal is increased, or the color of the light prompt signal is changed.

[0010] Optional, also includes: Monitor the battery level of the active electronic tag corresponding to the mold; Receive and generate low battery alert messages based on low battery warning information.

[0011] Optional, also includes: Receive mold information query requests or management operation requests; Based on preset role information and the corresponding permissions of each role, the system performs identity authentication and permission verification on the requester of the mold information query request or management operation request. In response to the mold information query request or management operation request that has passed identity authentication and permission verification, display the corresponding query results or perform the corresponding mold management operation.

[0012] Optional, also includes: Based on the current state of the mold, the mold is monitored to detect whether the state has changed. If so, the current state of the mold and the usage history of the mold are updated, the state change information of the mold is recorded and stored.

[0013] Corresponding to the mold management method for molded product production, the present invention provides a mold management system for molded product production, comprising: A mold status signal acquisition module is used to acquire mold status signals, which include timing signals representing mold opening and closing actions. The mold status judgment module is used to determine the current status of the mold based on the frequency characteristics and duration of the mold status signal. The status includes production status, trial mold status, maintenance status and idle status. The mold count module is used to count the number of opening and closing actions of the mold based on a timing signal after the mold has been used or after the mold has been used and a preset time has elapsed, and generate mold count data. The generation module is used to associate and store the status and number of times the mold is used with the unique identifier of the mold, and to generate the mold usage history.

[0014] In addition, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a mold production mold management program, which, when executed by a processor, implements the steps of the mold production mold management method described above.

[0015] Compared with existing technologies, this invention uses the frequency characteristics and duration of mold status signals to perceive the mold's operating status in real time and generate dynamic data, solving the problems of traditional QR code identification methods that cannot collect status in real time and have delayed data updates. This invention also utilizes time-series signals to count mold cycles, accurately quantifying mold usage and providing accurate data support for mold management; furthermore, it associates and stores mold status and cycle data to generate usage history, achieving refined management of the entire mold lifecycle and improving management efficiency and accuracy.

[0016] Compared with existing technologies, this invention can accurately distinguish between production, trial molding, maintenance and idle states by using the frequency characteristics and duration of mold status signals, providing a reliable basis for real-time monitoring and scheduling of molds.

[0017] Compared with existing technologies, this invention receives and sends an activation signal to the target mold according to the mold search instruction to trigger a positioning prompt signal, which can quickly locate the target mold and improve mold search efficiency. The positioning prompt signal of this invention incorporates sound and light elements, enriching the prompting methods, enhancing the recognizability of the target mold, and further improving the convenience and efficiency of mold search.

[0018] Compared with existing technologies, this invention dynamically adjusts sound and light prompts based on the distance between the user and the mold, intelligently optimizing the prompts to improve the user experience and ensure efficient positioning of the target mold at different distances.

[0019] Compared with existing technologies, this invention is designed for close-range scenarios by strengthening the intensity of sound prompts, increasing the repetition frequency or changing the tone, enhancing light brightness, increasing the flashing frequency or changing the color, making the prompts more eye-catching and further shortening the mold search time.

[0020] Compared with existing technologies, this invention monitors the power of active electronic tags, receives low power warnings and sends out prompts, providing early warnings of insufficient power, ensuring the continuous and stable operation of mold positioning and management functions, and avoiding management interruptions caused by power issues.

[0021] Compared with existing technologies, this invention introduces an identity authentication and permission verification mechanism to ensure the security and standardization of mold information query and management operations, prevent unauthorized access, and maintain the data security and operational order of the mold management system.

[0022] Compared with existing technologies, this invention monitors the mold status in real time, detects changes in status and updates them in a timely manner, and synchronously records status change information to the usage history, thereby realizing dynamic tracking and historical traceability of the mold status and providing comprehensive and real-time data support for mold management decisions.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. 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.

[0025] like Figure 1 As shown, the present invention provides a method for managing molds in the production of molded products, which includes the following steps: Acquire mold status signals, which include timing signals representing mold opening and closing actions; Based on the frequency characteristics and duration of the mold status signal, the current status of the mold is determined, including production status, trial molding status, maintenance status and idle status. After the mold is used, or after the mold is used and a preset time has elapsed, the number of times the mold opens and closes is counted based on the timing signal to generate mold count data. The mold status and mold count data are associated with the mold's unique identifier and stored, and a mold usage history is generated.

[0026] This invention uses the frequency characteristics and duration of mold status signals to perceive the mold's operating status in real time and generate dynamic data, solving the problems of traditional QR code identification methods that cannot collect status in real time and suffer from delayed data updates. This invention also utilizes time-series signals to count mold cycles, accurately quantifying mold usage and providing accurate data support for mold management; furthermore, it links and stores mold status and cycle data to generate usage history, achieving refined management of the entire mold lifecycle and improving management efficiency and accuracy.

[0027] Preferably, the preset duration is 10 minutes, but the specific duration can be set according to actual needs. The 10-minute duration is merely an example and does not constitute an undue limitation on the present invention. Furthermore, after generating the module count data, the module count data and the production date are uploaded to the gateway together.

[0028] Preferably, in this embodiment, the mold status signal can be sensed by the mold opening and closing sensor and uploaded to the mold management system. The mold opening and closing sensor converts the mold opening and closing action into a recognizable electrical signal, which is automatically recorded by a tag. After each mold production is completed, the updated data is automatically uploaded to the cloud server. The corresponding mobile application or web page management terminal of the mold management system can be viewed at any time from anywhere with network access.

[0029] In this embodiment, the timing signal refers to a series of electrical signals used to describe how the mold's opening and closing state (open or closed) changes over time. The mold's operation involves continuously "opening" and "closing." One "opening" and one "closing" constitute a complete cycle. The mold status signal can be collected by an opening and closing sensor and uploaded to the mold management system. When the mold is closed, the opening and closing sensor outputs a signal (e.g., a high level "1"). When the mold is open, the sensor outputs another different signal (e.g., a low level "0"). "Timing" emphasizes the order, duration, and frequency of these "1"s and "0"s.

[0030] In this embodiment, the current state of the mold is determined based on the frequency characteristics and duration of the mold state signal, specifically including: When the mold status signal exhibits a periodic change at a constant frequency (e.g., 1-0-1-0-1-0-1-0……1-0-1-0-1-0-1-0), and the duration is greater than or equal to the first duration threshold, the mold is determined to be in production state. When the mold status signal exhibits a non-constant frequency change (e.g., 1-0-……1-0-1-……0-1-0……1-0-……1-0-1-0-1-0……), and the duration is greater than or equal to the second duration threshold, the mold is determined to be in the trial molding state. When the mold status signal remains at a static signal value (e.g., 0) indicating that the mold is open, and the duration is greater than or equal to the third duration threshold, the mold is determined to be in maintenance status. When the mold status signal remains at a static signal value (e.g., 1) indicating mold closure for an extended period of time greater than or equal to the fourth duration threshold, the mold is determined to be in an idle state.

[0031] This invention can accurately distinguish between production, trial molding, maintenance and idle states by using the frequency characteristics and duration of mold status signals, providing a reliable basis for real-time monitoring and scheduling of molds.

[0032] In existing technologies, in warehouses or workshops where molds are densely packed, operators must rely on close-up scanning of QR codes or visual identification of mold numbers to locate the target mold. This process is time-consuming and labor-intensive, resulting in low efficiency in mold finding and location, and affecting mold management efficiency.

[0033] To address the aforementioned issues, in this embodiment, the method further includes receiving and sending an activation signal to the target mold according to a mold search instruction to trigger a positioning prompt signal; the mold search instruction includes at least a unique identifier for the target mold; the positioning prompt signal includes at least an audible prompt signal and a visual prompt signal.

[0034] This invention receives and sends an activation signal to the target mold according to the mold search instruction to trigger a positioning prompt signal, which can quickly locate the target mold and improve the mold search efficiency.

[0035] In this embodiment, the mold search command can be initiated by the user by inputting corresponding search criteria (such as mold number, specifications, or other relevant information) in the mold production mold management system (hereinafter referred to as the mold management system). The mold search command includes at least a unique identifier for the target mold. Furthermore, the method also includes: receiving and displaying detailed information about the target mold (such as its current location or current status) according to the mold search command.

[0036] This invention integrates sound and light elements into the positioning prompt signal, enriching the prompting methods, enhancing the recognizability of the target mold, and further improving the convenience and efficiency of mold retrieval.

[0037] In this embodiment, the method further includes: The system detects the distance between the user and the target mold and dynamically adjusts the sound and / or light prompts based on the distance.

[0038] This invention dynamically adjusts sound and light prompts based on the distance between the user and the mold, intelligently optimizing the prompts to improve the user experience and ensure efficient positioning of the target mold at different distances.

[0039] In this embodiment, the sound prompt signal is dynamically adjusted according to the distance. Specifically, when the distance between the user and the target mold is less than a first distance threshold, the intensity of the sound prompt signal is increased, the repetition frequency of the sound prompt signal is increased, or the tone of the sound prompt signal is changed. The light prompt signal is dynamically adjusted according to the distance. Specifically, when the distance between the user and the target mold is less than a first distance threshold, the brightness of the light prompt signal is increased, the flashing frequency of the light prompt signal is increased, or the color of the light prompt signal is changed.

[0040] This invention addresses close-range scenarios by enhancing the strength of sound prompts, increasing repetition frequency, or changing tone; and by increasing light brightness, increasing flashing frequency, or changing color, making the prompts more eye-catching and further shortening mold search time.

[0041] In this embodiment, the method further includes: Within the preset search time, wait for the successful search feedback information of the target mold. If the successful search feedback information is not received after the preset search time, the target mold search fails and a mold abnormal status prompt information is sent.

[0042] Preferably, successful search feedback information can be uploaded by the user or monitored by the mold management system.

[0043] In this embodiment, the method further includes: Monitor the battery level of the active electronic tag corresponding to the mold; Receive and generate low battery alert messages based on low battery warning information.

[0044] It should be noted that the active electronic tag is specifically a 2.4G active electronic tag, employing an ultra-low power consumption design, and can achieve a standby time of up to 10 years under normal use conditions. The active electronic tag can be installed on the corresponding mold and can store the basic information of the corresponding mold (such as mold number, specifications, production date, etc.) as well as the status of the corresponding mold.

[0045] In this embodiment, the active electronic tag is equipped with a low battery warning mechanism. When the battery level is lower than a preset battery threshold, it can send a low battery warning message to the mold management system through the gateway.

[0046] Preferably, the aforementioned gateway has a data caching function, which can temporarily store data when the network is unstable and resume uploading after the network is restored, ensuring data integrity. The gateway uses wireless communication technology to establish a stable communication link with the active electronic tags and the server, with a communication frequency of 2.4 GHz, ensuring high efficiency and anti-interference capabilities. The effective coverage range of the gateway in open areas is ≥200 meters, and each gateway can manage 1000 active electronic tags. Depending on the layout of the mold production area, gateways can be installed in suitable locations to ensure that the gateway's signal coverage can cover all areas where molds are located.

[0047] This invention monitors the battery level of active electronic tags, receives low battery warnings and sends out prompts, providing early warnings of insufficient battery power, ensuring the continuous and stable operation of mold positioning and management functions, and avoiding management interruptions due to battery issues.

[0048] In this embodiment, the method further includes: Receive mold information query requests or management operation requests; The system acquires and verifies the identity and permissions of requesters for mold information query or management operation requests based on preset role information (such as administrator, operator, maintenance personnel, etc.) and the corresponding permissions of each role (which can be set according to actual needs). Responding to mold information query requests or management operation requests that have passed identity authentication and permission verification, displaying the corresponding query results or executing the corresponding mold management operation.

[0049] This invention introduces an identity authentication and permission verification mechanism to ensure the security and standardization of mold information query and management operations, prevent unauthorized access, and maintain the data security and operational order of the mold management system.

[0050] Preferably, the management operation request includes at least one of the following: entry of information for any active electronic tag, update of the status of any mold, batch entry of active electronic tag information, batch update of mold status, and adjustment of role permissions.

[0051] In this embodiment, when the management operation request is for the input of any active electronic tag information, the status update of any mold, the batch input of active electronic tag information, or the batch update of mold status, the method further includes: verifying the input information to determine whether there are input errors and / or duplicate inputs (e.g., duplicate mold numbers). If there are input errors and / or duplicate inputs, the user is prompted to make corrections to ensure the integrity and accuracy of the data.

[0052] In this embodiment, the administrator can dynamically adjust user permissions by initiating management operation requests to adapt to changes in personnel and management needs within the enterprise.

[0053] In this embodiment, the method further includes: Based on the current state of the mold, the mold's status is monitored to detect whether the status has changed. If so, the current state of the mold and the mold's usage history are updated, the mold's status change information is recorded, and stored.

[0054] This invention achieves dynamic tracking and historical traceability of mold status by monitoring the mold status in real time, detecting status changes and updating them in a timely manner, and synchronously recording status change information to the usage history, thus providing comprehensive and real-time data support for mold management decisions.

[0055] In this embodiment, the mold status and mold count data are associated with and stored with the mold's unique identifier, and a mold usage history is generated; this includes at least the following steps: The mold status and mold count data are associated with and stored with the mold's unique identifier.

[0057] Furthermore, the mold status and mold count data are associated and stored with the mold's unique identifier, and a mold usage history is generated; this also includes: Obtain feedback on the execution of mold maintenance and repair tasks, which should at least include the reasons for maintenance and / or the content of maintenance. Based on feedback from mold maintenance tasks, status switching times, and production quantities, a mold usage history is generated.

[0058] In this embodiment, the method further includes: Based on the usage history of all molds, a visual display is created, including at least one of the following: a visual display of the mold list, detailed information about the molds (such as their current location or current status), and statistics on the distribution of mold status. This allows mold managers to quickly understand and analyze the overall situation of the molds.
