[0045] The words "preferably", "more preferably", etc. in the present invention refer to embodiments of the present invention that may provide certain beneficial effects in certain circumstances. However, other embodiments may also be preferred under the same circumstances or other circumstances. In addition, the description of one or more preferred embodiments does not imply that other embodiments are not applicable, nor is it intended to exclude other embodiments from the scope of the present invention.

[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention.

[0047] Please refer to Figure 1 , Figure 1 Schematic diagram of the hardware structure of a production line equipment maintenance management device in one embodiment of the present invention. The production line equipment maintenance management device includes components such as a communication module 01, a memory 02, and a processor 03. Those skilled in the art can understand that Figure 1 The terminal shown in the figure may also include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently. The processor 03 is connected to the memory 02 and the communication module 01 respectively, and the memory 02 stores a computer program, which is executed by the processor 03 at the same time.

[0048] The communication module 01 can be connected to an external device through a network. The communication module 01 can receive data sent by an external device, and can also send data, instructions and information to the external device, which can be an electronic device such as a mobile phone, a tablet computer, a laptop computer and a desktop computer.

[0049] The memory 02 can be used to store software programs and various data. The memory 02 can mainly include a program storage area and a data storage area, wherein the program storage area can store an application required for operating a production line equipment maintenance management device and at least one function (real-time acquisition of equipment information, location information and status information of the equipment), etc.; the data storage area can store data or information created according to the use of the terminal, etc. In addition, the memory 02 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0050] Processor 03 is the control center of the terminal. It uses various interfaces and lines to connect various parts of the entire terminal. It executes various functions of the terminal and processes data by running or executing software programs and / or modules stored in memory 02, and calling data stored in memory 02, so as to monitor the terminal as a whole. Processor 03 may include one or more processing units; preferably, processor 03 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operation of the production line equipment maintenance management device, the user interface and the application program, and the modem processor mainly processes wireless communication. It is understandable that the above-mentioned modem processor may not be integrated into processor 03.

[0051] The production line equipment maintenance management device includes an acquisition unit 04, a display 05, a processor 03 and a memory 02, wherein the processor 03 is electrically connected to the acquisition unit 04, the display 05 and the memory 02; the display 05 is used to display the layout model, and the equipment model in the layout model corresponds to the equipment on the production line one by one; the memory 02 is used to store a program, and when the program is read and executed by the processor 03, the processor 03 controls the acquisition unit 04 to obtain the equipment information, location information and status information of each equipment on the production line in real time; and locates the corresponding target model in the layout model according to the equipment information, and refreshes the target model based on the location information and / or status information, so that the display 05 generates and displays a dynamic visualization image. Combined with the refreshed equipment model position and status information, a dynamic visualization image can be generated. The image displays the current status of the production line in an intuitive way, including the layout of the equipment, the actual operating status of each equipment and the location information. It is possible to understand the overall operation of the production line at a glance without going deep into the site or relying on verbal reports. This high degree of transparency and visibility helps reduce misunderstandings and communication costs and improve management efficiency.

[0052] The locating a corresponding target model in the layout model according to the device information, and refreshing the target model based on the location information and the state information, includes:

[0053] Comparing two adjacent position information and two adjacent state information of the same device; the two adjacent position information includes current position information and historical position information, and the two adjacent state information includes current state information and historical state information;

[0054] Determine that the device model corresponding to the device whose position information or state information changes twice adjacently is the target model, and the device model corresponding to the device whose position information and state information are the same twice adjacently is the bottom model;

[0055] Based on the underlying model, the target model is moved according to the two adjacent position information, and the state identifier of the target model is changed according to the two adjacent state information.

[0056] During the refresh process, the position and state of the underlying equipment models in the layout model remain unchanged, providing a stable reference point for other equipment models to ensure the stability and consistency of the overall layout. These refresh operations are only performed on the target model to optimize the performance of the production line equipment maintenance management device and reduce unnecessary computing overhead. In other words, the refresh operation is only performed on the areas or elements that have changed to improve the efficiency and smoothness of the image refresh.

[0057] although Figure 1 Although not shown, the above-mentioned production line equipment maintenance management device may also include a circuit control module, which is used to connect to the mains to achieve power control and ensure the normal operation of other components.

[0058] Those skilled in the art will understand that Figure 1 The terminal structure shown in the figure does not constitute a limitation on the terminal, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0059] Based on the above hardware structure, the present application provides a method for dynamic display of production line equipment, aiming to improve the degree of visualization.

[0060] like Figure 2 As shown, in the first embodiment of the present application, the device dynamic display method:

[0061] Step S10, obtaining the equipment information, location information and status information of each equipment of the production line in real time;

[0062] In order to realize dynamic display, the production line equipment maintenance management device needs to be able to obtain relevant information from each device on the production line in real time. This includes but is not limited to the equipment information, location information and status information of the equipment; equipment information includes equipment ID, equipment type, etc.; location information includes X, Y, Z coordinate information, through which it can be determined whether the equipment is moving; status information: running, stopped, faulty, etc.

[0063] The production line equipment maintenance management device can also obtain production data, such as output, efficiency, etc., as well as other specific working parameter information that may be required, such as temperature, pressure, etc.

[0064] The methods for obtaining device information, location information and status information of the device include ultra-wideband wireless communication (UWB), radio frequency identification (RFID), image recognition technology, sensor detection technology and industrial Internet of Things technology.

[0065] Combining the real-time positioning production line equipment maintenance management device (RTLS) and the above-mentioned communication technology, a production line equipment maintenance management device that can collect equipment information in real time and comprehensively is constructed. The production line equipment maintenance management device ensures the real-time and accuracy of the data, providing a solid foundation for subsequent processing and analysis. The information obtained from different channels is integrated into a unified data platform for centralized management and processing. This includes data cleaning (removing redundant and erroneous data), integration (merging data from different sources into a unified format) and formatting (converting to a format that is easy to analyze and display) to ensure data consistency and accuracy.

[0066] This information can be obtained through technical means such as sensors built into the equipment, RFID tags, and the Industrial Internet of Things (IIoT).

[0067] Step S20: locating a corresponding target model in the layout model according to the device information, and refreshing the target model based on the location information and the status information to generate and display a dynamic visualization image;

[0068] Using Canvas rendering technology, 3D modeling software or other modeling tools, a digital virtual layout model is constructed based on the actual layout and configuration of the production line. The equipment models in the layout model correspond one-to-one to the equipment on the production line. The layout model can contain information such as the location, type, and connection relationship of all key equipment on the production line to facilitate subsequent mapping and dynamic display.

[0069] The production line equipment maintenance management device first searches for a corresponding equipment model in the layout model according to the acquired equipment information (such as equipment ID, serial number and other unique identifiers), and defines the corresponding equipment model as a target model.

[0070] According to the equipment location information, the production line equipment maintenance management device refreshes the position of the target model in the virtual layout in real time. That is, if the equipment in the production line moves, the corresponding target model will also move accordingly in the layout model to reflect the actual production line layout changes.

[0071] Based on the status information of the equipment (such as running, stopped, faulty, etc.), the production line equipment maintenance management device dynamically changes the display status of the target model. For example, different colors, icons or animation effects are used to represent different states of the equipment. This change helps operators quickly identify abnormal conditions of the production line and take corresponding measures.

[0072] In this application, a dynamic visualization image can be generated by combining the refreshed equipment model location and status information. The image shows the current status of the production line in an intuitive way, including the layout of the equipment, the actual operating status of each device, and the location information. It is possible to understand the overall operation of the production line at a glance without going to the site or relying on verbal reports. This high degree of transparency and visibility helps reduce misunderstandings and communication costs and improve management efficiency.

[0073] The production line equipment maintenance management device also includes obtaining production data, such as output, efficiency, etc., so that the layout model can show the overall performance of the production line.

[0074] Because the images are refreshed in real time, production managers can immediately detect abnormal conditions on the production line, such as equipment failure, reduced output or efficiency fluctuations. This real-time monitoring capability enables managers to respond quickly and take measures to resolve the problem, thereby preventing the problem from escalating and reducing production losses.

[0075] Understandably, it is possible to communicate with the terminal device so that the operation status of the production line can be viewed anytime and anywhere through a variety of terminal devices such as large screens, tablet computers, mobile phones, etc., which is conducive to making decisions more timely and accurately.

[0076] In the above embodiments, the layout model can be two-dimensional for simple planar display; or three-dimensional to provide a more intuitive sense of space and three-dimensionality. In other embodiments, in order to meet the viewing needs of different users or in different scenarios, the layout model can have a viewing angle adjustment function. The user can adjust the viewing angle as needed to better observe a certain area or equipment of the production line. At the same time, the layout model can also support switching between two-dimensional and three-dimensional display to meet the needs of different display platforms or display methods.

[0077] After completing the preliminary modeling, the layout model is optimized to improve its loading speed and rendering effect. Optimization measures may include reducing the number of model faces, optimizing material mapping, using LOD (Level of Detail) technology, etc.

[0078] After the layout model is built, it is necessary to find the corresponding device model in the model for each actual device and establish a unique correspondence between them. This usually involves matching information such as device number, model, location coordinates, etc. to ensure that each actual device can accurately find its representative in the model.

[0079] In one embodiment, a unique device ID is assigned to each device on the actual production line. This ID can be numbers, letters, or a combination thereof. The key is to ensure that there is no duplication in the entire production line equipment maintenance management device to ensure the uniqueness of the device. Ensure its uniqueness in the production line equipment maintenance management device. In the layout model, the same ID is also set for the corresponding device model for matching.

[0080] In addition to the device ID, other key attribute information of the actual device (such as model, specification, manufacturer, etc.) can also be entered into the device model of the layout model. This information not only helps to further confirm the correspondence between devices, but also provides richer information display in subsequent dynamic displays. When entering this information, it is necessary to ensure that it is consistent with the attribute information of the actual device in order to accurately match it.

[0081] like Figure 3 As shown, in the second embodiment of the present application, the step of locating the corresponding target model in the layout model according to the device information in step S20 includes:

[0082] Step S21, comparing two consecutive location information and two consecutive status information of the same device;

[0083] For each device on the production line, the production line equipment maintenance management device will set a timer (such as every second, every minute, etc.) to regularly obtain its latest location information and status information from the device, sensor or related data source.

[0084] This information includes two adjacent position information and two adjacent status information. The two adjacent position information can be the current position information and the historical position information, or the current position information and the target position information; the two adjacent status information can be the current status information and the historical status information, or the current status information and the target status information. In this embodiment, the two adjacent position information includes the current position information and the historical position information, and the two adjacent status information includes the current status information and the historical status information. The current position information is the current location data of the device, and the historical position information is the device location data recorded at the last update. The current status information is the current operating status, working mode, fault information, etc. of the device. The historical status information is the device status data recorded at the last update.

[0085] The production line equipment maintenance management device will compare the latest information obtained with the previously obtained information to detect any changes.

[0086] Step S22, determining that the device model corresponding to the device whose position information or the state information changes twice adjacently is the target model, and the device model corresponding to the device whose position information is the same twice adjacently and the state information is the same twice adjacently is the bottom model;

[0087] During the comparison process, if at least one of the two consecutive position information or status information of a device has changed, the device model corresponding to the device in the layout model is considered the target model. The target model needs to be updated to reflect the latest position and / or status. The remaining unchanged device models in the layout model are considered the underlying models, which remain static in the dynamic visualization image.

[0088] Step S23: Taking the underlying model as a reference, the target model is moved according to the two adjacent position information, and the state identifier of the target model is changed according to the two adjacent state information.

[0089] Once the target model is determined, the production line equipment maintenance management device will perform one or both of the following operations to update the model:

[0090] Move the target model according to the position information:

[0091] If the position information of the equipment changes between two consecutive times, the production line equipment maintenance management device will use the underlying model as the reference (keeping the positions of other unchanged equipment unchanged) to calculate the distance and direction that the target model needs to move. Then, the target model is moved accordingly in the dynamic visualization image to reflect the new position of the target model.

[0092] Change the state flag of the target model according to the state information:

[0093] If the status information of the equipment changes between two consecutive times, the production line equipment maintenance management device will change the status identification of the target model in the dynamic visualization image. This may include changing the color of the model, displaying different icons, adding or removing specific visual effects (such as flashing, rotation, etc.), so that operators can intuitively identify the status change of the equipment.

[0094] During the refresh process, the position and state of the underlying equipment models in the layout model remain unchanged, providing a stable reference point for other equipment models to ensure the stability and consistency of the overall layout. These refresh operations are only performed on the target model to optimize the performance of the production line equipment maintenance management device and reduce unnecessary computing overhead. In other words, the refresh operation is only performed on the areas or elements that have changed to improve the efficiency and smoothness of the image refresh.

[0095] Specifically, local canvas rendering technology can be used to replace traditional global canvas refresh rendering. Local rendering determines the specific components that need to be refreshed through component IDs, and only re-renders the changed areas (target models), thereby greatly reducing unnecessary computing overhead and rendering time. Since local rendering is only performed on changed components, the number of component refreshes required is greatly reduced compared to global refresh, significantly improving overall rendering performance.

[0096] In other embodiments, the device models may be classified according to whether the device position is fixed or not, and the devices with fixed position and less status change, or the devices that do not need to be frequently refreshed and displayed in the layout model even if the status changes, are defined as the bottom device models. The devices whose position or status may change frequently and these changes need to be reflected in the layout model in real time are defined as the target models.

[0097] Based on the above embodiment, the layout model can be an offline model based on canvas color rendering. The step of determining that the device model corresponding to the device whose position information or status information has changed twice adjacently is the target model, and the device model corresponding to the device whose position information is the same twice adjacently and whose status information is the same twice adjacently is the underlying model includes: obtaining the device information of the device whose position information or status information has changed twice adjacently; performing color identification on the layout model according to the color comparison relationship between the device information and the device model to determine the target model, and the rest is the underlying model.

[0098] In the layout model, each equipment model is assigned a unique equipment ID and mapped to a specific color. This mapping relationship allows the production line equipment maintenance management device to quickly locate the corresponding equipment model by identifying the color.

[0099] When the production line equipment maintenance management device receives the device information including the device ID, it can find the corresponding color by querying the mapping relationship. Then, the production line equipment maintenance management device can render the color on the layout model. Through the color picking function of the native canvas, the production line equipment maintenance management device can check the color value of a specific position on the layout model to determine the position and identity of the target model.

[0100] The drawing and color picking functions of the canvas are used to accurately identify internal components. By converting the unique ID of the component into a color and rendering it on the layout model, the production line equipment maintenance management device can accurately analyze the pixels on the canvas through the color picking function to identify the specific component. Since the canvas color picking function has pixel-level accuracy, this method also achieves extremely high accuracy in identifying the equipment model in the layout model.

[0101] Equipment information includes equipment type, such as overhead crane, manipulator, cutting machine, material tray, etc. The equipment type determines the dimension of the equipment's location information and the refresh method of the equipment model.

[0102] The step of moving the target model according to the two adjacent position information comprises:

[0103] When the equipment type of the target model is an overhead crane, the trolley position, the car position and the hoist position of the overhead crane are refreshed according to two adjacent X coordinate information, the trolley position and the hoist position of the overhead crane are refreshed according to two adjacent Y coordinate information, and the hoist position of the overhead crane is refreshed according to two adjacent Z coordinate information.

[0104] like Figure 4 and Figure 5 As shown in the figure, for a device such as an overhead crane, its position information is subdivided into X coordinates (carriage position), Y coordinates (trolley position) and Z coordinates (hanger position). This subdivision enables the production line equipment maintenance and management device to more accurately control the position of the overhead crane in three-dimensional space. Through PLC (programmable logic controller) communication technology, the production line equipment maintenance and management device can obtain various position data of the overhead crane in real time. As the core control device in industrial automation, PLC can accurately monitor and control the operating status of various industrial equipment. According to the received position information, the production line equipment maintenance and management device will refresh the position of the overhead crane in the layout model. Specifically, the X coordinate is used to refresh the position of the overhead crane's trolley, that is, the horizontal movement of the overhead crane. When the trolley is moved, the trolley and the hanger move with the trolley; the Y coordinate is used to refresh the trolley position, that is, the vertical movement of the trolley on the overhead crane. When the trolley is moved, the hanger and the trolley move with the trolley; and the Z coordinate is used to refresh the hanger position, that is, the vertical lifting of the hanger. In this way, users can intuitively see the movement of the crane on the crane track, the movement of the trolley on the beam, and the lifting of the spreader. This dynamic visualization not only improves the real-time monitoring, but also enhances the user's perception of the operating status of the production line.

[0105] like Figure 6 As shown, in the third embodiment of the present application, the production line equipment dynamic display method further includes:

[0106] Step S31, obtaining the target position information of the overhead travelling crane;

[0107] Step S32, calculating the running track of the overhead travelling vehicle according to the current position information and the target position information of the overhead travelling vehicle;

[0108] The two adjacent position information may be the current position information and the historical position information, or the current position information and the target position information.

[0109] The current position information is the precise position of the overhead crane, which may include X, Y coordinates (two-dimensional plane) or X, Y, Z coordinates (three-dimensional space), and possible orientation or angle information. The target position information is the next position that the overhead crane needs to reach, which also includes precise position and orientation information.

[0110] The process information needs to be accurately stored in the memory. This process information may include the tasks of each station on the production line, the current status of the equipment, the movement path of the product, and the target position coordinates. This information is usually stored in the form of a data table, a data structure, or a file in a specific format. When it is necessary to obtain the target position information of a specific device, the production line equipment maintenance management device can read the relevant process information from the memory.

[0111] In some cases, the target position information may not be stored directly, but needs to be calculated through other data items. For example, if the memory stores the relative position and motion instructions of the equipment, the production line equipment maintenance management device needs to calculate the target position based on these instructions and the current position of the equipment. This usually involves algorithms such as coordinate transformation and path planning.

[0112] After obtaining the current position information and target position information of the overhead crane, the production line equipment maintenance management device calculates the operation trajectory of the overhead crane. This calculation process may take into account a variety of factors, such as the maximum speed, acceleration, deceleration, obstacles on the path, safety distance, etc. of the overhead crane. By comprehensively considering these factors, the production line equipment maintenance management device can plan an optimal or feasible operation trajectory to ensure that the overhead crane can reach the target position safely and efficiently.

[0113] Step S33: superimposing dynamic lines on the layout model according to the running track of the overhead crane.

[0114] After calculating the running track of the overhead crane, the production line equipment maintenance management device can visualize the running track on the layout model. This is usually achieved by superimposing dynamic lines on the model. The dynamic lines can be a simple set of line segments or complex graphics with animation effects, such as curves, arrows, etc. The color, thickness and animation effect of the dynamic lines can be adjusted as needed to clearly display the running path of the overhead crane.

[0115] Through the above methods, users can intuitively see the future running direction and path of the overhead crane, which is conducive to monitoring the overall operation status of the production line, predicting potential problems or conflicts, and making timely scheduling and adjustments.

[0116] In one embodiment, the step of moving the target model according to the position information includes:

[0117] When the device type of the target model is a material pallet, the device model corresponding to the material pallet is moved according to the two adjacent position information, and the time comparison relationship between the material pallet and the workstation is generated and stored according to the workstation and device ID where the material pallet is located.

[0118] After obtaining the location information of the material tray, the production line equipment maintenance management device will reflect this information on the interface in real time. Specifically, the production line equipment maintenance management device will move the material tray model on the interface according to the current location information of the material tray, so that the location of the material tray model is consistent with the actual location of the material tray, such as Figure 7 At the same time, the production line equipment maintenance management device will also generate and store time comparison relationships based on the workstation where the material tray is located and the corresponding equipment ID, and these comparison relationships can be used for subsequent tracing and analysis.

[0119] In actual applications, each material pallet can be equipped with an RFID (Radio Frequency Identification) tag. When the material pallet is transported to different workstations on the production line, the RFID reader at the workstation will automatically read the information in the RFID tag, including the unique identifier of the material pallet, current status, etc.

[0120] The PLC receives data from the RFID reader and stores it in an internal database or transmits it to the host computer through the network for further processing. In this way, the production line equipment maintenance management device can obtain the location information of the material pallet at each workstation in real time.

[0121] After obtaining the location information of the material tray, the production line equipment maintenance management device will reflect this information on the interface in real time. Specifically, the production line equipment maintenance management device will move the material tray model on the interface according to the current location information of the material tray to keep it consistent with the actual location. At the same time, the production line equipment maintenance management device will also generate and store time comparison relationships based on the workstation where the material tray is located and the corresponding equipment ID. These comparison relationships can be used for subsequent tracing and analysis.

[0122] Based on the above embodiment, the production line equipment dynamic display method further includes:

[0123] When a material tray query instruction is received, the historical track of the material tray is displayed according to the time comparison relationship between the material tray and the workstation.

[0124] The material tray query instruction can be a user interface that inputs the device ID of the material tray or a selected material tray model, and displays the material tray trajectory information according to the time comparison relationship between the material tray and the workstation.

[0125] The production line equipment maintenance management device needs to provide a user interface that allows the user to enter the equipment ID of the material pallet or select the material pallet model. This interface can be web-based, desktop-based, or touch-screen, depending on the actual situation of the production line and user needs. The user can specify the material pallet to be queried by entering the equipment ID, scanning the QR code, clicking the list item or the icon on the map, etc. At the same time, this user interface can also be used to display the layout model.

[0126] Once the user specifies the equipment ID of the material tray, the production line equipment maintenance management device will retrieve the trajectory information of the material tray based on the previously stored time correspondence between the material tray and the workstation. These correspondences usually include the workstation, equipment ID and other possible status information of the material tray at different time points.

[0127] The production line equipment maintenance management device can use this information to construct the movement trajectory of the material pallet and display it graphically on the interface. The trajectory information can be one or more continuous line segments, representing the movement path of the material pallet on the production line. For a more intuitive display, these line segments can have color, width or animation effects to distinguish different workstations, time periods or states.

[0128] By displaying the trajectory information of the material pallet, users can quickly understand the flow of the material pallet on the production line, including which stations the material pallet has stayed at, the length of time it has stayed, and whether it has moved along the predetermined route. This can help production managers identify potential problems or bottlenecks in a timely manner and take appropriate measures to adjust and optimize.

[0129] In addition, the track information can also be used to trace the material flow and quality issues during the production process. If a batch of products has a problem, the production manager can trace the source of the problem by querying the track information of the relevant material pallets, so as to quickly locate the problem and take measures to solve it.

[0130] The layout model includes several working areas; in one embodiment, Figure 7 and Figure 8 As shown, in the fourth embodiment of the present application, the production line equipment dynamic display method further includes:

[0131] Step S40: When there is a biological signal in any working area, a warning message is displayed in the working area.

[0132] The production line equipment maintenance management device can divide the entire production line into several areas according to the operating range and layout characteristics of the equipment on the production line. These areas can be based on physical space division (such as different production line sections, work areas, etc.), or they can be based on equipment functions or process flows. The purpose of dividing the areas is to better manage and monitor the operating status of the production line and to more accurately locate potential safety hazards.

[0133] In each area, the production line equipment maintenance management device will deploy biological signal detection equipment, such as infrared sensors, cameras combined with AI recognition technology, to monitor in real time whether there are unauthorized personnel or other organisms in the area. These devices can capture specific signals emitted by organisms (such as infrared radiation, image features, etc.) and compare them with preset thresholds or patterns to determine whether there are safety hazards.

[0134] Once a biological signal is detected in any area and the signal meets the preset warning conditions (such as personnel entering a dangerous area, not wearing protective equipment, etc.), the production line equipment maintenance management device will immediately display a warning message in the area. The warning message can be presented in a variety of forms, such as highlighting the area boundary, popping up a warning window, sounding an alarm, etc., to attract the attention of production managers or on-site operators.

[0135] By introducing zoning and bio-signal detection functions, the safety status of the production line can be monitored in real time and an early warning can be issued immediately when hidden dangers are found. This implementation method not only helps to prevent safety accidents, but also improves the overall operation efficiency of the production line. Reducing downtime and production delays caused by safety accidents can ensure the continuous and stable operation of the production line, thereby improving production efficiency and product quality.

[0136] Specifically, the biological signal includes a detection signal emitted by a security door or a signal emitted when an image recognition system recognizes image data of a biological body in an area.

[0137] Safety gates are common safety devices in production lines, usually used to control the entry and exit of personnel to ensure that only authorized personnel can enter specific areas. When the safety gate is opened or detects that an object (especially a biological organism) passes through, it will send a detection signal. This signal can be captured by the production line equipment maintenance management device and used as a basis for judging whether there are unauthorized personnel in the area. If the production line equipment maintenance management device detects that the safety gate is opened or a person passes through without authorization, it can immediately display an early warning message in the area to alert production managers or on-site operators.

[0138] The image recognition system combines cameras and AI technology to capture and analyze image data in the production line area in real time. Through preset algorithms and models, the production line equipment maintenance management device can identify organisms (such as people, animals, etc.) in the image and determine whether they are in a dangerous area or are not wearing necessary protective equipment. Once a potential safety hazard is identified, the production line equipment maintenance management device will immediately send a signal and trigger the display of early warning information. The advantage of the image recognition system is that it can cover a wider area and is not restricted by physical obstacles, thereby improving the comprehensiveness and accuracy of safety monitoring.

[0139] Early warning information can be presented in a variety of forms to suit different monitoring needs and environmental conditions. Highlighting area boundaries can intuitively point out potential danger areas; pop-up warning windows can provide more detailed safety tips and operational suggestions; and sound alarms can quickly attract the attention of on-site operators to ensure that they can respond in time. These diverse early warning information helps improve the overall safety of the production line and reduce the probability of safety accidents.

[0140] For example, on the floor plan, each production area corresponds to a safety lock icon. This icon intuitively reflects the safety status of the area through color changes. When the production line equipment maintenance management device detects that there are workers working in the area, the safety lock icon will be displayed in red to warn production managers and on-site operators that there are potential safety risks in the area. On the contrary, if the area is in normal operation and there are no safety hazards, the safety lock icon will be displayed in green, indicating that the area is safe.

[0141] In addition, each workstation (equipment) is assigned a clear task, and the production line equipment maintenance management device can receive the content of these tasks in real time and display them clearly on the interface. At the same time, the production line equipment maintenance management device can also track and record the completion of each task, including completed steps, current progress, expected completion time, etc. In this way, managers can quickly understand the working status of each workstation, discover and solve potential problems in a timely manner, and ensure the smooth progress of production tasks.

[0142] Through the data collection of PLC and the data fusion of the visual production line equipment maintenance management device, the production line equipment maintenance management device can obtain the working position information of various types of equipment in real time. The equipment may include robots, cutting machines, overhead cranes, material pallets, etc. Fig. 9 and Fig.10As shown in the figure, for cutting machines, the production line equipment maintenance and management device can accurately display the position of the cutting head, cutting path and cutting progress; for robots, the production line equipment maintenance and management device can track the picking and placing actions of its mechanical arm, and even display the image and weight information of the grasped object; for fixed-position equipment such as trusses, the production line equipment maintenance and management device can also display its working status and load conditions. This real-time dynamic display not only helps users intuitively understand the workflow and efficiency of the equipment, but also provides data support for the optimization of the production line.

[0143] The present invention also provides a computer-readable storage medium on which a computer program is stored. The computer-readable storage medium may be Figure 1 The memory 02 in the terminal may also be at least one of a ROM (Read-Only Memory) / RAM (Random Access Memory), a magnetic disk, and an optical disk. The computer-readable storage medium includes some information for enabling the production line equipment maintenance management device to execute the methods described in the various embodiments of the present invention.

Those skilled in the art should understand that any improvement of the present invention, equivalent replacement of the method of the present invention, addition of auxiliary steps, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
