Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical safety production, and particularly to a safety production monitoring method and device for a bar and wire rod workshop. Background Art

[0002] Each process section in the bar and wire rod workshop has a clear division of labor and is closely linked, with a relatively fast production rhythm. During the rolling and shearing processes, events such as steel piling and flying steel occur from time to time. Moreover, the production process has a high temperature, and operators need to work in a high-temperature and high-pressure environment, with many dangerous areas. Therefore, the safety management of the bar and wire rod workshop is particularly important. The traditional safety monitoring method uses single-point video monitoring, which can only monitor local positions and has disadvantages such as many monitoring blind spots, slow response speed, and untimely response to problems.

[0003] Currently, the video monitoring in the bar and wire rod workshop is all single-point monitoring. Only the video images captured by the front-end cameras are arranged on the display screen in the order of production, and the monitoring images are independent and discontinuous. However, in the bar and wire rod workshop, especially the high-speed wire rod workshop, the rolling speed is extremely fast, which can reach 40m / S, that is, 144km / h. Conventional single-point monitoring cannot display the complete and continuous rolling process of a billet in the image of a single camera, and cannot effectively perform video analysis and processing.

[0004] The current digital twin system for the bar and wire rod workshop has achieved modeling at the contour level or even component level of the main equipment, and can completely display the entire production process of the workshop. However, the digital twin system for the bar and wire rod workshop is only a dynamic simulation animation of the workshop production process based on various production data, not a real-time scene image of the workshop production, and cannot directly and truly display the actual situation of the workshop production.

[0005] Moreover, the current virtual reality integration system is relatively complex, resulting in a greater impact on the data transmission speed. However, the rolling speed is fast, which has an adverse impact on the refined monitoring of safety production in the bar and wire rod workshop. Summary of the Invention

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer and more understandable, the following will further describe the embodiments of the present invention in detail with reference to the drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0056] Figure 1 is a schematic flowchart of a method for monitoring safe production in a bar and wire rod workshop provided by an embodiment of the present invention. As Figure 1 shown, the method for monitoring safe production in a bar and wire rod workshop provided by an embodiment of the present invention includes:

[0057] Step S1: Obtain the video image of the target area captured by the camera, and integrate the video image into the three-dimensional model of the bar and wire rod workshop established in advance to obtain a panoramic monitoring model of the workshop;

[0058] Among them, the target area is the area where billet production is located.

[0059] Step S2: Determine the rolling area boundary in the workshop panoramic monitoring model, and monitor the running speed of the billet within the rolling area boundary.

[0060] Step S3: Correct the running speed of the billet according to the performance information of the target equipment, and realize the safe production monitoring of the bar and wire rod workshop according to the corrected running speed of the billet.

[0061] In the above step S1, the device acquires the video image of the target area captured by the camera, and integrates the video image into the three-dimensional model of the bar and wire rod workshop established in advance to obtain the workshop panoramic monitoring model;

[0062] Among them, the target area is the area where the billet production is located. The device can be a computer device that executes this method. In the technical solution of this application, the acquisition, storage, use, processing, etc. of data all comply with relevant regulations. Before executing the method of the present invention, a system can be built, such as Figure 2 As shown, the system includes a network high-definition camera (clarity: 1080P), a network switch, a video storage network hard disk recorder (NVR), a video management server, a three-dimensional fusion server, and an image workstation.

[0063] The description of establishing the three-dimensional model of the bar and wire rod workshop is as follows: The three-dimensional model of the bar and wire rod workshop can be established by means of three-dimensional modeling technology and in combination with the two-dimensional drawings of the workshop. The steps of establishing the three-dimensional model of the workshop mainly include the following stages:

[0064] Requirement analysis and on-site inspection: First, it is necessary to comprehensively understand the requirements of the workshop, including the daily work process, ideas for equipment layout, and future development plans. Collect this information by communicating with management personnel and front-line workers. Then conduct on-site inspections and record detailed information such as the spatial dimensions of the workshop, the positions of doors and windows, and the routing of ventilation ducts.

[0065] Data collection and preparation: Collect the specification parameters of all equipment in the workshop, production line layout, logistics channel data, etc. These data include the geometric dimensions, shape characteristics, and movement ranges of mechanical moving parts of the equipment. At the same time, measure the basic data such as the dimensions of the factory building, the positions and sizes of doors and windows.

[0066] Select a suitable modeling software: Select a suitable modeling software according to the project requirements, such as 3ds Max, SolidWorks, etc. These software provide rich model libraries and tools, which can help complete the construction of the three-dimensional model of the workshop.

[0067] Draw a preliminary sketch: Draw a preliminary sketch of the workshop on paper, outlining the general outline of the workshop and the positions of the main equipment. This sketch will provide a direction for subsequent digital modeling.

[0068] Building the basic model: In the modeling software, accurately create a three-dimensional spatial framework of the workshop based on the data measured on-site. Add equipment models one by one and adjust them according to the specific parameters of the equipment. If there is no suitable model in the model library, it is necessary to create it by oneself.

[0069] Adding details and materials: Add realistic textures and details to the model. Adjust parameters such as the reflectivity and roughness of the materials to make the model look like real metal, wood, or plastic in the virtual environment. At the same time, add texture maps and material properties to the model to increase its realism and aesthetics.

[0070] Lighting settings and rendering: Reasonably set the position, brightness, and color of the lights to achieve better lighting and shadow effects. After completing the modeling, texturing, and lighting settings, perform rendering and output to convert the three-dimensional model into a two-dimensional image and save it.

[0071] According to the overall layout of the workshop, select a suitable location to deploy cameras to obtain real-time video images of multiple single-point cameras. As Figure 3 shown, according to the characteristics of the bar and wire rod workshop's sequential production from front to back, and considering the convenience of daily production process maintenance and repair, the cameras are set on the workshop building columns on the side of the main rolling bay with a viewing platform or a crane maintenance platform.

[0072] The description of obtaining the workshop panoramic monitoring model is as follows: Perform scene fusion and edge processing on the real-time video images collected by the cameras and the three-dimensional model to generate a workshop panoramic monitoring model. This model should contain detailed information such as various areas of the workshop, key equipment, and safety channels. Edge processing includes removing duplicate content captured by multiple cameras or filling in missing content between the content captured by adjacent two cameras.

[0073] Multiple intelligent cameras collect panoramic video images of the bar and wire rod workshop. According to the image sequence and position information, the real-time monitoring videos of different positions and with different perspectives distributed in the production line area are dynamically fused into the real three-dimensional scene model in real time. The airspace segmented by the cameras is reconnected into a whole, and edge processing at the junctions of different cameras and time delay processing throughout the process are performed to achieve the fusion of the virtual scene and the real-time video, establish the perception ability of the real-time video in the virtual three-dimensional space, generate a real-time panoramic monitoring model of the workshop, and realize the fusion display of the virtual reality panoramic video in the whole area.

[0074] In step S2 above, the device determines the boundary of the rolling area in the workshop panoramic monitoring model and monitors the running speed of the billets within the boundary of the rolling area. The boundary of the rolling area in the workshop panoramic monitoring model can be determined through panoramic video AI analysis.

[0075] Monitoring the running speed of the billet within the boundary of the rolling area includes:

[0076] Determining the starting position and the ending position for billet speed measurement according to the boundary of the rolling area;

[0077] Starting timing when the billet runs to the starting position and ending timing when the billet runs to the ending position;

[0078] Calculating the running speed of the billet based on the time difference between the end timing and the start timing and the distance between the starting position and the ending position;

[0079] Determining the monitoring result of the billet running speed according to whether the billet running speed is lower than the preset speed threshold.

[0080] On the panoramic monitoring model of the workshop, perform panoramic video AI analysis, delimit the boundary of the rolling area, determine fixed positions as the starting position and the ending position for billet speed measurement. When the head of the billet on the rolling line reaches the starting position, start timing, and when it reaches the ending position, end timing. Calculate the running speed of the billet within this interval according to the distance and the time difference between the starting position and the ending position.

[0081] The preset speed threshold can be set independently according to the actual situation. The safety production monitoring method for the bar and wire rod workshop further includes:

[0082] Monitoring whether the billet exceeds the boundary of the rolling area by using the panoramic video AI analysis method, and realizing the safety production monitoring of the bar and wire rod workshop according to the monitoring result of the billet position.

[0083] The implementation of panoramic video AI analysis mainly includes the following key steps and technologies:

[0084] Video access and decoding: First of all, the panoramic video needs to enter the system through a specific access method. Common access methods include directly accessing from the camera or accessing through the video management platform. After access, the video needs to be decoded because the input for deep learning inference requires RGB - format pictures.

[0085] Object detection and tracking: The decoded video frames are input into the object detection model for inference to lock the target of interest. After object detection, object tracking is required to ensure the association of the targets in the front and back frames.

[0086] Attribute classification and behavior analysis: After object detection and tracking, it is necessary to classify the attributes of the target, such as target type, credibility, and position, etc. Further behavior analysis can identify the actions and scenarios of the target, so as to conduct more refined analysis.

[0087] Data analysis and presentation: Finally, present the analysis results in data form, including target trajectory analysis, target behavior analysis, image overlay, etc. These results can be presented to users after encoding.

[0088] During the trial operation of the platform, measure the billet running speed of different billets and store the data in the database to establish the initial database of the interval billet running speed, as shown in Table 1:

[0089] Table 1

[0090]

[0091] Manually calibrate the initial running database, and select the threshold of the interval speed when abnormal events such as billet piling up and flying steel occur, that is, the preset speed threshold. During the stable production operation of the platform, detect the billet running speed through the workshop panoramic monitoring model. When the billet running speed is lower than the preset speed threshold, it means that the billet is subject to additional resistance and the forward speed of the billet will slow down, and it is considered that a production abnormal event may occur. A message pop-up window is displayed on the workshop panoramic monitoring model as a warning message. As Figure 4 shown, at the same time, call the panoramic video AI analysis result to determine whether there is a billet outside the boundary range of the rolling area. If not, the warning is lifted. If so, a pop-up window is highlighted on the workshop panoramic monitoring model to remind the operator to judge and handle the abnormal situation in time, and send the alarm information to relevant management personnel in real time through the push platform (such as mobile APP, SMS, email, etc.).

[0092] Through the analysis of the alarm information, generate relevant report statistics by cycle, and count the occurrence categories, frequencies, occurrence areas, etc. of abnormal events, providing a basis for the safety management of the bar and wire rod workshop.

[0093] In the above step S3, the device corrects the billet running speed according to the performance information of the target device, and realizes the safety production monitoring of the bar and wire rod workshop according to the corrected billet running speed. The target device can be Figure 2 at least one of the devices. The performance information of the target device can affect the network speed, thereby increasing the transmission time of the video image, which results in the billet running speed displayed through the workshop panoramic monitoring model being slower than the actual billet running speed. In order to monitor the billet running speed more accurately later, it is necessary to correct the billet running speed.

[0094] The target device includes a network switch; correspondingly, the correction of the billet running speed according to the performance information of the target device includes:

[0095] If it is determined that the response time of the network switch continues to increase, and the duration during which the throughput of the network switch continues to decrease after reaching the maximum value reaches a first preset duration, the billet running speed is corrected at a preset speed increment. Taking billet No. 1 as an example, the start time for counting the response time of the network switch can be selected as the moment when billet No. 1 just reaches the edge of the rolling area boundary. If the response time continues to increase while the billet has not left the rolling area, it means that the first correction condition is met.

[0096] In addition, within a short period of time after the throughput of the network switch starts to decrease after reaching the maximum value, such as 0.2S, the network state starts to deteriorate at this time. After analysis and demonstration, it will have a certain impact on the accuracy of monitoring the billet running speed at this time. Therefore, the first preset duration can be selected as 0.2S. If the duration during which the throughput of the network switch continues to decrease after reaching the maximum value reaches the first preset duration, it means that the second correction condition is met. When both correction conditions are met, the correction of the billet running speed can be triggered. The preset speed increment can be set independently according to the time situation. Further, if the speed at which the response time continues to increase is faster or the maximum value of the throughput is higher, a larger preset speed increment can be set. If the speed at which the response time continues to increase is slower or the maximum value of the throughput is lower, a smaller preset speed increment can be set.

[0097] The safety production monitoring method for the bar and wire rod workshop further includes:

[0098] If it is determined that the duration during which the throughput of the network switch continues to decrease after reaching the maximum value reaches a second preset duration, a network fault warning message is generated; the second preset duration is greater than the first preset duration. The second preset duration can be set independently according to the actual situation and can be selected as 1S. If the duration during which the throughput of the network switch continues to decrease after reaching the maximum value is relatively long, since the billet running speed of billet No. 1 has been corrected before this time and the network speed further deteriorates, it means that the monitoring result of the billet running speed of billet No. 1 is inaccurate, and it is necessary to call the monitoring system in the actual production process to obtain the billet running speed of billet No. 1. Generating a network fault warning message can prompt relevant personnel to handle it to prevent the subsequent occurrence of inaccurate monitoring results of the billet running speed caused by network faults for billet No. 2.

[0099] The safety production monitoring method for the bar and wire rod workshop further includes:

[0100] Obtain a first time difference between the start timing moment and the moment when the billet runs to the starting position recorded in the video image, and obtain a second time difference between the end timing moment and the moment when the billet runs to the ending position recorded in the video image; Referring to the above description, the moment when the billet runs to the starting position and the moment when the billet runs to the ending position recorded in the video image can be understood as the shooting time of the video image captured by the camera. Taking the billet running to the starting position as an example, the video image needs to be transmitted and loaded into the workshop panoramic monitoring model thereafter and participate in calculating the running speed of the billet. Since the start timing moment represents the current moment when the billet runs to the starting position, this will result in a lag between the current moment and the moment when the billet runs to the starting position recorded in the video image. This lagged first time difference can reflect the "time delay" of the "time delay processing of the whole process" to a certain extent. Similarly, the lag corresponding to the second time difference can also reflect the above-mentioned time delay to a certain extent.

[0101] Determine the delay change trend information of the video image transmitted to the workshop panoramic monitoring model according to the comparison result of the first time difference and the second time difference, and adjust the model accuracy parameters of the workshop panoramic monitoring model according to the delay change trend information. If the first time difference is greater than the second time difference, or the first time difference is less than or equal to the second time difference, but the data comparison amplitude is within the preset time difference, it means that the delay of the video image transmitted to the workshop panoramic monitoring model does not change much, and the model accuracy parameters of the workshop panoramic monitoring model do not need to be adjusted. The preset time difference can be set independently according to the actual situation.

[0102] If the first time difference is greater than the second time difference, and the data comparison amplitude exceeds the preset time difference, it is determined that the delay in the workshop panoramic monitoring model changes in a better direction, and the model accuracy parameters of the workshop panoramic monitoring model can be increased, so that the image quality of the workshop panoramic monitoring model is higher and the display detail information is more clearly reflected.

[0103] If the first time difference is less than the second time difference, and the data comparison amplitude exceeds the preset time difference, it is determined that the delay in the workshop panoramic monitoring model changes in a worse direction, and the model accuracy parameters of the workshop panoramic monitoring model can be decreased, so that the image quality of the workshop panoramic monitoring model is lower and the display detail information does not need to be reflected to ensure the smoothness of data transmission.
