[0039] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0041] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0042] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] With the continuous development of the steel industry, the safety problem in the operation process of converter is paid more and more attention. The traditional safety management method depends on manual patrol and fixed position monitoring camera, and these methods have certain limitations, such as incomplete monitoring coverage, slow response, inability to accurately judge personnel behavior in complex scene, etc. In recent years, with the development of image recognition technology, it is possible to use machine vision for safety monitoring.

[0044] At present, there are some safety management systems based on video monitoring and image recognition applied in industrial production. These systems obtain live video streams through fixed cameras and use pre-trained models for target detection to realize the monitoring of personnel behavior in specific areas. For example, some systems can detect the entry or exit of personnel into specific areas to judge safety hazards and issue alarms.

[0045] However, the prior art has the following defects:

[0046] 1. Low recognition accuracy; In complex industrial environments, existing image recognition models cannot adapt to changing lighting conditions and complex backgrounds, resulting in low recognition rates.

[0047] 2. Lack of dynamic response; Existing systems are mostly passive monitoring, with slow response speed to sudden conditions, and cannot effectively warn in real time.

[0048] 3. Cannot distinguish between working conditions; Existing technologies cannot distinguish the specific operating state of the converter, such as smelting, adding molten iron, or loading scrap steel, etc., resulting in the system being unable to dynamically adjust the monitoring strategy according to the actual working conditions.

[0049] 4. Poor integration; Most systems fail to effectively integrate with the existing safety management platform of the enterprise, and the real-time and availability of data are insufficient, making it difficult to achieve comprehensive safety production management.

[0050] In combination Figure 1 The present application provides a safety monitoring method for a converter platform, which includes steps 101 to 104:

[0051] Step 101: Collecting image data of the converter platform and PLC signals related to converter control;

[0052] In this embodiment, the image data of the converter platform can be collected by a camera. The camera is installed at multiple key positions on the converter platform, covering the entire platform area, and can adjust the angle and focal length as needed to ensure no dead angle monitoring.

[0053] The camera has high dynamic range (HDR) and can obtain clear images in strong light and shadow areas, and has night vision function to ensure stable operation of the system under different lighting conditions.

[0054] It should be noted that the PLC signal of the converter control is a primary signal, which can identify the operating state of the converter, but due to being a primary signal, the accuracy is not high or the signal lags, affecting the timeliness and accuracy of obtaining the operating state of the converter. And the method of this embodiment belongs to equipment modification. In order to improve the timeliness and accuracy of obtaining the operating state of the converter, this embodiment no longer simply relies on the PLC signal of the converter control when determining the current operating state of the converter.

[0055] Step 102: According to the PLC signal and the image data, determine the current operating state of the converter;

[0056] In this embodiment, when determining the current operating state of the converter, the PLC signal and the image data are used together to determine the current operating state of the converter, and the specific steps can include:

[0057] According to the PLC signal, an initial operation state of the converter is determined;

[0058] According to the initial operation state, a verification parameter is determined;

[0059] According to the verification parameter, the image data is analyzed to determine a current operation state of the converter.

[0060] In the embodiment, the operation state of the converter is preliminarily determined according to the PLC signal to obtain the initial operation state of the converter. Then, the verification analysis is performed in combination with the image data, and the image data is recognized and analyzed through the target model.

[0061] It should be noted that the operation state of the converter mainly includes a smelting state, a molten iron adding state and a scrap steel loading state. Different operation states have different verification parameters and different verification manners.

[0062] Firstly, the verification parameter is determined according to the initial operation state. The verification parameter includes a duration of a target object and a light intensity of the target object.

[0063] Specifically, in the smelting state, the corresponding target object is a damper, and the corresponding verification parameter is a light intensity of a side gap of the damper. The change of the light intensity reflects the fluctuation of the temperature in the converter. In combination with the PLC signal, whether the converter is really in the smelting state is determined by judging the light intensity of the side gap of the damper.

[0064] In the molten iron adding state, the corresponding target object is a molten iron ladle, and the corresponding verification parameter is a duration of the molten iron ladle. In combination with the adjacent historical image data, whether the converter is really in the molten iron adding state is determined by judging the duration of the appearance of the molten iron ladle.

[0065] In the scrap steel loading state, the corresponding target object is a scrap steel bucket, and the corresponding verification parameter is a duration of the scrap steel bucket. In combination with the adjacent historical image data, whether the converter is really in the scrap steel loading state is determined by judging the duration of the appearance of the scrap steel bucket.

[0066] The duration can be 10 seconds.

[0067] Step 103: According to the current operation state of the converter, a safety area corresponding to the current operation state is determined;

[0068] In this embodiment, a safety area is defined for each converter, which is flexibly set by the operator according to the actual production environment and process requirements. The safety area can be a rectangular, circular or polygonal area, and dynamic adjustment is supported. The safety area is dynamically adjusted, specifically, the range of the safety area is dynamically adjusted according to different converter operating states (such as smelting, adding molten iron, loading scrap steel, etc.). That is, according to the current operating state of the converter, the safety area corresponding to the current operating state is determined.

[0069] Step 104: Safety monitoring of the converter platform according to the image data of the converter platform and the safety area.

[0070] Specifically, the image data is input into the trained target model for target recognition to detect whether there is a target person in the safety area corresponding to the image data.

[0071] If there is a target person in the safety area, an alarm information is issued.

[0072] In this embodiment, the target model uses a trained YOLO (You Only Look Once) deep learning model to recognize personnel, ladle, scrap steel bucket and other targets in the image data. The model considers complex industrial environment factors such as smoke, heat wave, dynamic changes of process equipment, etc. during training, to ensure the robustness of recognition.

[0073] To improve the accuracy of target recognition, the image data collected in this embodiment is preprocessed, including image denoising, gray scale adjustment and edge enhancement.

[0074] In the recognition process, if there is a target person in the safety area, it means that there is a safety risk, at which time an alarm information is issued, that is, a real-time voice alarm is issued through a loudspeaker to remind the target person on site to evacuate immediately.

[0075] Moreover, at the same time when the alarm information is issued, the current monitoring screen is automatically intercepted, and relevant information (such as time, heat number, target person position, etc.) is saved. These screenshots are stored according to date and event type, which is convenient for subsequent viewing and analysis.

[0076] It should be noted that this embodiment also designs a multi-level alarm mechanism to issue different levels of alarms according to the severity of the event. For example, when the target person only approaches the safety area, the system issues a low-level warning; when the person enters a high-risk area, the system issues an emergency alarm.

[0077] In addition, this embodiment also includes steps for personnel approach detection and behavior prediction:

[0078] If the target personnel does not exist in the safety area, a peripheral early warning area corresponding to the current operation state is determined according to the safety area;

[0079] It is detected whether the target personnel exists in the peripheral early warning area;

[0080] If the target personnel exists in the peripheral early warning area, historical image data adjacent to the image data is acquired;

[0081] The motion trajectory of the target personnel in a preset time period is predicted according to the image data and the historical image data;

[0082] If the motion trajectory of the target personnel in the preset time period reaches the safety area, an early warning information is sent.

[0083] A region in the periphery of the safety area can be used as the peripheral early warning area. In this embodiment, the motion trajectory of the personnel is analyzed, and when it is detected that the target personnel is in the peripheral early warning area, it is indicated that the target personnel approaches the safety area. The motion trajectory of the target personnel in a short time is analyzed in combination with the historical image data adjacent to the image data, so as to determine whether the target personnel is likely to enter the safety area. If the motion trajectory of the target personnel in the preset time period reaches the safety area, an early warning information is sent, that is, a voice prompt is sent through a loudspeaker to remind the target personnel to pay attention to safety. This function can effectively avoid potential dangerous behaviors. The preset time period is in the range of 2-5 seconds.

[0084] In addition, this embodiment has a behavior analysis function and can determine whether the behavior of the personnel has potential danger. For example, the system can identify abnormal behaviors such as rapid movement or wandering and send an early warning accordingly.

[0085] In summary, the safety monitoring method of the converter platform provided in this specification collects image data of the converter platform and PLC signals about converter control; determines the current operation state of the converter according to the PLC signals and the image data; determines a safety area corresponding to the current operation state according to the current operation state of the converter; and performs safety monitoring on the converter platform according to the image data of the converter platform and the safety area. In this way, through a high-precision target detection algorithm and a dynamic working condition recognition technology, real-time monitoring of the behavior of personnel on the converter platform is realized, and in particular, when dangerous operations such as converter smelting, iron water mixing, and waste steel loading are performed, the system can automatically identify and send an early warning, thereby preventing the occurrence of safety accidents.

[0091] Optionally, the monitoring unit is further configured to:

[0093] if there is a target person in the safety region, issue an alarm information.

[0094] Optionally, the monitoring unit is further configured to:

[0095] if there is no target person in the safety region, determine a peripheral early warning region corresponding to the current operation state according to the safety region;

[0097] if there is a target person in the peripheral early warning region, acquire historical image data adjacent to the image data;

[0098] predict a motion trajectory of the target person within a preset time period according to the image data and the historical image data;

[0099] if the motion trajectory of the target person within the preset time period reaches the safety region, issue an early warning information.

[0100] Optionally, the preset time period is within a range of 2-5 seconds.

[0101] Optionally, the target model is a YOLO model.

[0102] Optionally, the region determination unit is further configured to:

[0103] determine an initial operation state of the converter according to the PLC signals;

[0104] determine a verification parameter according to the initial operation state;

[0105] According to the check parameter, the image data is analyzed to determine a current operation state of the converter.

[0106] Optionally, the check parameter includes a duration of the target object and a light intensity of the target object.

[0107] To sum up, the safety monitoring device of the converter platform provided by the embodiments of the present disclosure collects image data of the converter platform and PLC signals related to the control of the converter; determines a current operation state of the converter according to the PLC signals and the image data; determines a safety area corresponding to the current operation state of the converter according to the current operation state of the converter; and performs safety monitoring on the converter platform according to the image data of the converter platform and the safety area. In this way, through a high-precision target detection algorithm and a dynamic working condition recognition technology, real-time monitoring of the behavior of personnel on the converter platform is realized, and in particular, when the converter is smelting, the converter is being filled with molten iron, and the converter is being loaded with scrap steel, the system can automatically identify and issue a warning, thereby preventing the occurrence of safety accidents.

[0108] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the safety monitoring device of the converter platform described above can refer to the corresponding process in the foregoing method, and will not be described in more detail here.

[0109] Based on the same inventive concept, the embodiments provide an electronic device including the safety monitoring device of the converter platform, a memory, a processor, and a communication unit. The memory stores machine-readable instructions executable by the processor. When the electronic device is running, the processor and the memory communicate through a bus.

[0110] The memory, the processor, and the communication unit are directly or indirectly electrically connected to each other to realize the transmission or interaction of signals. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines.

[0113] For ease of illustration, only one processor is described in the electronic device. However, it should be noted that the electronic device in the embodiments can also include multiple processors, and thus the steps performed by one processor described in the embodiments can also be jointly performed by multiple processors or individually performed by multiple processors. For example, if the processor of the server performs steps A and B, it should be understood that steps A and B can also be jointly performed by two different processors or individually performed in one processor. For example, the processor performs step A, the second processor performs step B, or the processor and the second processor jointly perform steps A and B.

[0125] To improve recognition accuracy, the system pre-processes the collected images, including image denoising, grayscale adjustment, and edge enhancement.

[0128] Outside the set safety area, the system creates a peripheral warning area, and any target entering this area will be monitored in real time by the system.

[0129] The system dynamically adjusts the range of the safety area according to the different current operating states of the converter (such as smelting, adding molten iron, and loading scrap steel).

[0130] State recognition module:

[0131] By analyzing the light intensity of the side gap of the converter fire door, the system can determine whether the converter is in a smelting state.
