Description

Technical Field

[0001] This invention belongs to the field of steel ladle information recognition technology, specifically relating to a method and system for steel ladle information recognition in steel plants. Background Technology

[0002] Currently, there are several problems with the identification of ladle numbers within steel plants:

[0003] 1. The package number recognition system is not operating normally and stably. Package number recognition cameras are located throughout the steel plant, in various processes, tracks, and pits. If each camera is constantly recognizing packages, it will put a significant load on the server.

[0004] 2. The accuracy of steel ladle identification timing is relatively low. Because the camera for ladle number recognition has a limited shooting range, accurate identification can only be performed when the ladle's number plate is completely visible within that area; otherwise, the accuracy is reduced due to the limited shooting range. In actual production processes, the accuracy of steel ladle identification timing is indeed low.

[0005] 3. The accuracy of package number identification results is not guaranteed. The low accuracy of identification leads to a lack of assurance regarding the accuracy of the results, which further affects the accuracy of information sent by the logistics tracking system to other secondary systems. This also negatively impacts the evaluation of information such as the grade, age, and condition of the steel packages. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies. This invention provides a method and system for identifying steel ladle information in a steel plant. This invention avoids the server load caused by all cameras in the steel plant continuously taking pictures and identifying lumens, and helps cameras take pictures and identify lumens at the accurate time and location, while simultaneously sending the accurate ladle number to the logistics tracking system. This invention plays a dominant role in determining the timing of camera picture identification and can, to some extent, overcome the performance limitations of the ladle number identification server, thereby improving the accuracy of ladle number identification.

[0007] To achieve the desired effect, the present invention adopts the following technical solution:

[0008] This invention discloses a method for identifying steel ladle information in a steel plant, comprising:

[0009] When the material tracking system of the steel plant detects that the overhead crane is performing a preset action at the working point, it obtains the crane's position information;

[0010] Retrieve camera information data for steel ladle identification points corresponding to the crane's location from the database;

[0011] The camera is triggered to take pictures by using the information of the steel bag information identification point data to achieve steel bag information identification.

[0012] Furthermore, the preset actions include at least one of picking up the package, dropping the package, and dispensing materials.

[0013] Furthermore, the specific steps for obtaining the camera steel ladle information identification point data corresponding to the crane position include: delineating the camera installation position according to the location of the working point, determining the camera shooting range according to the camera installation position, and determining the camera steel ladle information identification point data according to the camera shooting range.

[0014] Furthermore, the camera steel bag information identification point data includes: whether the camera has started identifying the working point, the number of times the camera has triggered identification, the number of times the camera has received identification, the camera identification bag number, and the camera identification bag type.

[0015] Furthermore, the method also includes: pre-configuring the camera steel package information identification point data in the PLC and database.

[0016] Furthermore, the specific steps for triggering the camera to take pictures using the information identification point data of the steel ladle to achieve steel ladle information identification include:

[0017] Increment the camera's recognition count by 1 and write it into the PLC;

[0018] When the camera processing service reads from the PLC that the number of times the camera triggers recognition has changed, it triggers the camera to continuously capture a preset number of images and send them to the image recognition server for recognition.

[0019] Furthermore, the method also includes:

[0020] The identified preset quantity results are categorized and analyzed to obtain the most accurate steel ladle information, which is then written into the PLC.

[0021] At the same time, the number of times the camera receives recognition data is assigned to the number of times the camera triggers recognition and written into the PLC;

[0022] When the logistics tracking system scans the data in the PLC and reads that the number of times the camera receives and recognizes data equals the number of times the camera triggers recognition, it obtains the most accurate information about the steel bag recognized by that camera.

[0023] Furthermore, the method also includes: obtaining the camera's shooting range by querying the database, and comparing the steel ladle information corresponding to the camera's shooting range in the database with the latest steel ladle information identified by the camera. If there is a discrepancy in the steel ladle information, the database is updated using the latest steel ladle information identified by the camera.

[0024] Furthermore, the steel ladle information includes at least one of the following: ladle number and ladle type.

[0025] This invention also discloses a steel ladle information identification system for steel plants, comprising:

[0026] The data acquisition module is used to collect various data required for identifying information about steel ladles.

[0027] The identification module is used to identify steel ladle information according to any of the methods described above.

[0028] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention provides a method and system for identifying steel ladle information in steel plants. Cameras are installed at various locations in the logistics tracking system where actions such as ladle lifting, ladle unloading, and material loading occur to capture images. When the crane performs these actions at the corresponding locations, the cameras continuously capture complete ladle numbers and send them to the server for identification. This invention significantly reduces the load on the ladle number identification server in steel plants and relaxes the performance requirements of the server, thus improving the efficiency of the ladle number identification system. This invention can precisely control the timing and range of ladle number identification, ensuring that the corresponding shooting location has a complete ladle number to be identified during the image capture and identification process by combining it with logistics tracking actions. This invention performs multiple continuous image captures after the camera is triggered, ensuring the accuracy of the identification results. Attached Figure Description

[0029] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] Figure 1 This is a flowchart of a method for identifying steel ladle information in a steel plant, provided by an embodiment of the present invention. Detailed Implementation

[0031] 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, and not all embodiments. 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.

[0032] See Figure 1 This invention discloses a method for identifying steel ladle information in a steel plant, comprising:

[0033] When the material tracking system of the steel plant detects that the overhead crane is performing a preset action at the working point, it obtains the crane's position information;

[0034] Retrieve camera information data for steel ladle identification points corresponding to the crane's location from the database;

[0035] The camera is triggered to take pictures by using the information of the steel bag information identification point data to achieve steel bag information identification.

[0036] Generally, a complete package number identification process in a logistics tracking system consists of three stages: camera triggering, continuous camera shooting, and return of identification results. This invention equips cameras at the locations where various actions occur in the logistics tracking system, such as bag lifting, bag unloading, and material exchange. When the crane performs these actions at the corresponding locations, the cameras continuously capture the complete package number of the steel ladle and send it to the server for identification. This invention significantly reduces the load on the steel plant's package number identification server, relaxes the performance requirements of the server, and improves the efficiency of the package number identification system. This invention can precisely control the timing and range of package number identification, ensuring that the corresponding shooting location has a complete package number to be identified during the photo-taking and identification process by combining it with logistics tracking actions. This invention performs multiple continuous shooting and identification after camera triggering, ensuring the accuracy of the identification results.

[0037] Preferably, the preset action includes at least one of lifting the package, dropping the package, and dispensing the material.

[0038] In a preferred embodiment, the specific steps for obtaining the camera steel ladle information identification point data corresponding to the crane position include: delineating the camera installation position according to the location of the working point, determining the camera shooting range according to the camera installation position, and determining the camera steel ladle information identification point data according to the camera shooting range.

[0039] Specifically, the installation locations of cameras within the steel plant are determined based on the locations of the overhead crane's loading, unloading, and material exchange areas.

[0040] Furthermore, the camera steel bag information identification point data includes: whether camera X has started identifying working points CamX_On, the number of times camera X has triggered identification CamX_Sen_Times, the number of times camera X has received identification CamX_RCV_Times, the identification bag number CamX_LadleNo, and the identification bag type CamX_LadleType.

[0041] Preferably, the method further includes: pre-configuring the camera steel package information identification point data in the PLC and database.

[0042] Furthermore, the specific steps for triggering the camera to take pictures using the information identification point data of the steel ladle to achieve steel ladle information identification include:

[0043] Increment the camera's recognition count by 1 and write it into the PLC;

[0044] When the camera processing service reads from the PLC that the number of times the camera triggers recognition has changed, it triggers the camera to continuously capture a preset number of images and send them to the image recognition server for recognition.

[0045] For example, when the logistics tracking system tracks the overhead crane to perform actions such as picking up, dropping, and dispensing materials in a certain area, it finds the camera in that area from the database, increments the camera's recognition count CamX_Sen_Times by 1, and writes it into the PLC. The camera processing service reads the change in CamX_Sen_Times data from the PLC and triggers the camera to start taking 8 consecutive pictures, which are then sent to the image recognition server for recognition.

[0046] A PLC (Programmable Logic Controller) is a digital electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, controlling various types of machinery or production processes through digital or analog inputs and outputs.

[0047] Furthermore, the method also includes:

[0048] The identified preset quantity results are categorized and analyzed to obtain the most accurate steel ladle information, which is then written into the PLC.

[0049] At the same time, the number of times the camera receives recognition data is assigned to the number of times the camera triggers recognition and written into the PLC;

[0050] When the logistics tracking system scans the data in the PLC and reads that the number of times the camera receives and recognizes data equals the number of times the camera triggers recognition, it obtains the most accurate information about the steel bag recognized by that camera.

[0051] For example, the 8 identified results are categorized and the most accurate package number and package type data are analyzed; the most accurate package number and package type data are written into the CamX_LadleNo and CamX_LadleType points in the PLC respectively, and the number of received identifications CamX_RCV_Times is assigned the value CamX_Sen_Times and written into the PLC.

[0052] When the logistics tracking system scans the data in the PLC, if it reads that CamX_RCV_Times equals CamX_Sen_Times, it obtains the most accurate package number and package type data identified by the camera.

[0053] Furthermore, the method also includes: obtaining the camera's shooting range by querying the database, and comparing the steel ladle information corresponding to the camera's shooting range in the database with the latest steel ladle information identified by the camera. If there is a discrepancy in the steel ladle information, the database is updated using the latest steel ladle information identified by the camera.

[0054] Furthermore, the steel ladle information includes at least one of ladle number and ladle type. It is foreseeable that the present invention can also use the same working principle to identify other steel ladle information.

[0055] This invention avoids the server load caused by all cameras in a steel plant constantly taking pictures and identifying packages. It also helps cameras take pictures and identify packages at the precise time and location, while simultaneously sending accurate package numbers to the logistics tracking system. This invention prioritizes the timing of camera image capture and identification, and to some extent overcomes the performance limitations of package number identification servers, thereby improving the accuracy of package number identification.

[0056] This invention also discloses a steel ladle information identification system for steel plants, comprising:

The processor can invoke logical instructions from the memory to execute a method for identifying steel ladle information in a steel plant, including:

[0063] The camera is triggered to take pictures by using the information of the steel bag information identification point data to achieve steel bag information identification.
