Description

A method and system for tracking dumped materials in steel plant containers Technical Field

[0001] The invention belongs to the technical field of tracking dumped materials in steel plant containers, and in particular relates to a method and system for tracking dumped materials in steel plant containers. Background Art

[0002] Currently, there are several problems with tracking container dumping in steel plants:

[0003] 1. Existing technologies cannot accurately track tipping movements and immediately transmit them to the corresponding secondary system. Container tipping tracking is primarily used to transmit start and end signals to the corresponding secondary process, ensuring smooth operation of the secondary process. Therefore, real-time tracking is crucial.

[0004] 2. The existing technology cannot accurately determine whether it is a dumping action or a bag dropping action, because both the dumping action and the bag dropping action show a decrease in weight in the weight curve analysis.

[0005] 3. Existing technology cannot accurately track the location information of the dumping action. Only by accurately tracking the location information of the dumping action can the process where the dumping action occurs be accurately found and the signal can be transmitted to the corresponding process level.

[0006] 4. Existing technology cannot accurately track the weight of dumped materials. Only by accurately tracking the weight of dumped materials can the secondary calculation of molten steel weight information be facilitated in each process.

[0007] Summary of the Invention

[0008] The purpose of the present invention is to overcome the defects of the prior art. The present invention provides a method and system for tracking material dumping from a steel plant container. The present invention can accurately distinguish between dumping actions and bag dropping actions in real time, and can also determine the corresponding process based on the location where the dumping action occurs, and send the dumping start and end signals to the corresponding process level 2, ensuring that the process level 2 can be smoothly promoted and operated.

[0009] In order to achieve the expected effect, the present invention adopts the following technical solutions:

[0010] The present invention discloses a method for tracking dumped materials in a steel plant container, comprising:

[0011] When the overhead crane is found to be in a stationary state, the duration of the stationary state of the overhead crane is recorded;

[0012] When the duration of the overhead crane stationary state is greater than or equal to the first time, obtaining coordinate data of the location of the overhead crane;

[0013] According to the coordinate data, detecting whether corresponding process information and ground ladle information exist at a position corresponding to the coordinate data;

[0014] When it is detected that at least one of the corresponding process information and the ground steel ladle information exists at the position corresponding to the coordinate data, it is determined whether the overhead crane generates a dumping action at the position corresponding to the coordinate data by continuously tracking the overhead crane weighing data;

[0015] When it is detected that the corresponding process information and ground steel ladle information do not exist at the position corresponding to the coordinate data, it is determined that the overhead crane does not generate a dumping action at the position corresponding to the coordinate data.

[0016] Furthermore, the signals of the four directions of the overhead crane, namely, the forward movement of the overhead crane, the backward movement of the overhead crane, the left movement of the trolley, and the right movement of the trolley, are tracked in real time. When there is no movement signal of the overhead crane in the four directions, it is determined that the overhead crane is in a stationary state at this time.

[0017] Furthermore, the step of continuously tracking the overhead crane weighing data to determine whether the overhead crane has tipped over at the position corresponding to the coordinate data specifically includes:

[0018] Start recording the duration of the overhead crane's dumping action;

[0019] Obtain the initial gross weight of the container hoisted by the crane based on the weighing data when the crane is in a stationary state;

[0020] Continuously track the crane weighing data and obtain the crane weighing data in the second time;

[0021] If the difference between the initial gross weight of the container hoisted by the crane and the crane weighing data within the second time is greater than or equal to the crane tipping weight threshold, and the crane weighing data within the second time is greater than the empty container weight, the crane weighing data within the second time is assigned to the initial gross weight of the container hoisted by the crane, and the crane tipping action duration is increased by 1 second.

[0022] When the overhead crane movement signal is tracked within the second time, or the overhead crane weighing data within the second time is less than or equal to the empty container weight, or the overhead crane weighing data within the second time is greater than the initial gross weight of the container lifted by the overhead crane, the overhead crane will not generate a dumping action at the position corresponding to the coordinate data.

[0023] Furthermore, when the overhead crane does not generate a tipping action at the position corresponding to the coordinate data, the duration of the overhead crane tipping action and the duration of the overhead crane stationary state are set to 0.

[0024] Furthermore, the method of obtaining the initial gross weight of the container hoisted by the overhead crane based on the weighing data when the overhead crane is in a stationary state specifically includes: obtaining the overhead crane weighing data within a first time period, using a median filter to filter the salt and pepper noise in the overhead crane weighing data within the first time period, and then taking the average value, and using the average value as the initial gross weight of the container hoisted by the overhead crane.

[0025] Furthermore, when the duration of the overhead crane's tilting action is greater than or equal to a third time, the overhead crane generates a tilting action at the position corresponding to the coordinate data.

[0026] Furthermore, when the duration of the overhead crane tilting action does not change within the fourth time period, or when the overhead crane movement signal is tracked, the overhead crane tilting action ends at this time.

[0027] Furthermore, the method also includes: when the overhead crane dumping action is completed, the dumping action completion signal and the weight of the dumped material are sent to the corresponding process secondary equipment to complete the tracking of this dumping action, and the weight of the dumped material is equal to the difference between the current gross weight of the overhead crane lifting container and the initial gross weight.

[0028] Furthermore, the weighing data of the crane in the fifth time period is obtained, and the salt and pepper noise in the weighing data of the crane in the fifth time period is filtered out using a median filter, and the average value is taken as the current gross weight of the container hoisted by the crane.

[0029] The present invention also discloses a steel plant container dumping material tracking system, comprising:

[0030] The collection module is used to collect various data required for tracking the dumping of materials in containers in steel plants;

[0031] A tracking module is used to track materials dumped from containers in a steel plant according to any of the above methods.

[0032] Compared with existing technologies, the present invention has the following advantages: It provides a method and system for tracking material dumping from steel mill containers. The system can accurately identify dumping actions in real time and distinguish them from bag dropping. It can also determine the corresponding process based on the location of the dumping action and send dumping start and end signals to the corresponding process's secondary equipment, ensuring the smooth operation of the process's secondary equipment. The system can accurately locate the dumping location and the weight of the dumped material, thereby promoting the smooth operation of each process's secondary equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0034] FIG1 is a flow chart of a method for tracking dumped materials from a steel plant container provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] Referring to FIG1 , the present invention discloses a method for tracking dumped materials in a steel plant container, comprising:

[0037] Step 1: When the overhead crane is found to be in a stationary state, start recording the duration of the stationary state of the overhead crane;

[0038] Preferably, the signals of the four directions of the overhead crane trolley moving forward, the trolley moving backward, the trolley moving left and the trolley moving right are tracked in real time. When there is no movement signal of the overhead crane in the four directions, it is determined that the overhead crane is in a stationary state at this time.

[0039] Specifically, a Gray busbar is installed in the span where the overhead crane operates, and a sensing device is installed on the side of the overhead crane closest to the Gray busbar to locate the crane's X coordinate during operation. A ranging laser is installed at the end of the trolley track on the overhead crane to obtain the trolley's position, or Y coordinate. The X and Y coordinates of each overhead crane are connected to the Gray busbar PLC system. The overhead cranes are modified to include a weighing device to obtain real-time weighing signals. The weighing signals use a 4-20mA signal or can be connected to the Gray busbar PLC system via communication. For example, signals for the crane's forward, backward, left, and right trolley movements are connected to the Gray busbar PLC system. A 1 signal indicates movement in that direction, while a 0 signal indicates no movement in that direction.

[0040] Exemplarily, the X and Y coordinates of the corresponding step-up process of the position of the overhead crane are calibrated and stored in the database; when the overhead crane drops the bag, the position information of the overhead crane is recorded in the database; when the overhead crane picks up the bag at this position, the position information is deleted; the database is also used to record the position information of the steel bag in the steel plant; the overhead crane movement signal in the PLC is obtained, and when the signals in the four directions of the trolley moving forward, the trolley moving backward, the trolley moving left, and the trolley moving right are all 0 and last for a period of time (for example, 8 seconds), it is judged that the overhead crane is in a stationary state.

[0041] Step 2: When the duration of the overhead crane stationary state is greater than or equal to the first time, obtaining coordinate data of the location of the overhead crane;

[0042] For example, a variable craneStill with an initial value of 0 is created to record the duration of the crane's stationary state. When craneStill is equal to 8s, the X and Y coordinate data of the crane's position are obtained from the Gray bus PLC.

[0043] Step 3: Detecting, based on the coordinate data, whether corresponding process information and ground steel ladle information exist at the position corresponding to the coordinate data;

[0044] When it is detected that at least one of the corresponding process information and the ground steel ladle information exists at the position corresponding to the coordinate data, it is determined whether the overhead crane generates a dumping action at the position corresponding to the coordinate data by continuously tracking the overhead crane weighing data;

[0045] When it is detected that the corresponding process information and ground steel ladle information do not exist at the position corresponding to the coordinate data, it is determined that the overhead crane does not generate a dumping action at the position corresponding to the coordinate data.

[0046] Exemplarily, detecting whether process information corresponding to the coordinate data exists in the first database;

[0047] If it is detected that the process information corresponding to the coordinate data exists in the first database, then the crane is judged whether a dumping action occurs at the position corresponding to the coordinate data by continuously tracking the crane weighing data; if it is detected that the process information corresponding to the coordinate data does not exist in the first database, then the second database is further checked for ground steel ladle information corresponding to the coordinate data;

[0048] If it is detected that the ground steel ladle information corresponding to the coordinate data exists in the second database, it is determined whether the overhead crane generates a dumping action at the position corresponding to the coordinate data by continuously tracking the overhead crane weighing data; if the ground steel ladle information corresponding to the coordinate data is not detected in the second database, it is determined that the overhead crane does not generate a dumping action at the position corresponding to the coordinate data.

[0049] The present invention can accurately distinguish between the dumping action and the bag dropping action in real time, and can also determine the corresponding process according to the location where the dumping action occurs, and send the dumping start and end signals to the corresponding process secondary equipment, ensuring that the process secondary equipment can operate smoothly.

[0050] Furthermore, the step of continuously tracking the overhead crane weighing data to determine whether the overhead crane has tipped over at the position corresponding to the coordinate data specifically includes:

[0051] Start recording the duration of the overhead crane dumping action; specifically, create a variable weightReduce with an initial value of 0 to record the duration of the overhead crane dumping action;

[0052] Obtain the initial gross weight of the container hoisted by the crane based on the weighing data when the crane is in a stationary state;

[0053] Continuously track the crane weighing data and obtain the crane weighing data within the second time (for example, 3 seconds);

[0054] If the difference between the initial gross weight of the container hoisted by the crane and the crane weighing data within the second time is greater than or equal to the crane dumping weight threshold pourOffset, and the crane weighing data within the second time is greater than the empty container weight ladleWeight, the crane weighing data within the second time is assigned to the initial gross weight of the container hoisted by the crane, and the crane dumping action duration is increased by 1s.

[0055] When the overhead crane movement signal is tracked within the second time, or the overhead crane weighing data within the second time is less than or equal to the empty container weight, or the overhead crane weighing data within the second time is greater than the initial gross weight of the container lifted by the overhead crane, the overhead crane will not generate a dumping action at the position corresponding to the coordinate data.

[0056] In a preferred embodiment, when the overhead crane does not generate a tipping action at the position corresponding to the coordinate data, the duration of the overhead crane tipping action and the duration of the overhead crane stationary state are set to 0.

[0057] Furthermore, the method of obtaining the initial gross weight of the container hoisted by the overhead crane based on the weighing data when the overhead crane is in a stationary state specifically includes: obtaining the overhead crane weighing data within a first time period, using a median filter to filter the salt and pepper noise in the overhead crane weighing data within the first time period, and then taking the average value, and using the average value as the initial gross weight of the container hoisted by the overhead crane.

[0058] For example, the weighing data of the overhead crane in a stationary state for 8 seconds is recorded, and the salt and pepper noise in the weighing data is filtered using a median filter, and the average value is taken as the initial gross weight Weight0 of the container hoisted by the overhead crane.

[0059] On the one hand, when the duration of the overhead crane dumping action is greater than or equal to the third time (for example, 5 seconds), the overhead crane generates a dumping action at the position corresponding to the coordinate data and sends a signal to the corresponding process level 2.

[0060] On the other hand, when the duration of the overhead crane tilting action does not change within the fourth time (eg, 15 seconds), or when the overhead crane movement signal is tracked, the overhead crane tilting action is terminated at this time.

[0061] On the other hand, the method also includes: when the overhead crane dumping action is completed, the dumping action end signal and the weight of the dumped material are sent to the corresponding process secondary equipment to complete the tracking of this dumping action. The weight of the dumped material is equal to the difference between the current gross weight of the overhead crane lifting container and the initial gross weight.

[0062] Furthermore, the weighing data within the fifth time period (e.g., 8s) of the overhead crane is obtained, and the salt and pepper noise in the weighing data within the fifth time period of the overhead crane is filtered out using a median filter, and the average value is taken as the current gross weight of the container hoisted by the overhead crane.

[0063] Exemplarily, real-time weighing data of the overhead crane is continuously obtained and compared with the initial gross weight of the container hoisted by the overhead crane. When the weight difference exceeds a certain range and the weighing data at this time is greater than the empty bag weight of the container hoisted by the overhead crane, it is determined that the weight of the container hoisted by the overhead crane is decreasing at this time, and the initial gross weight of the container hoisted by the overhead crane is updated with the overhead crane weighing data at this time.

[0064] When it is continuously determined that the weight of the container decreases for more than a certain number of times, it is determined that the container is dumping materials at this time, and a dumping material signal is sent to the corresponding process secondary equipment.

[0065] When it is determined that the gross weight of the container fluctuates within a fixed small range within a certain period of time, it is determined that the container has finished dumping the material, and the gross weight of the container at this time is recorded; the gross weight of the container at this time is subtracted from the initial gross weight of the container to obtain the weight data of the dumped material; and the dumping end signal and the dumping material weight data are sent to the corresponding process secondary equipment.

[0066] The present invention relates to tracking the dumping of materials from containers in an overhead crane logistics system within a steel enterprise. The tracked actions include converting scrap steel to converter, converting iron to converter, folding iron from desulfurization, folding cans, etc., and the weight of the dumped materials is recorded in real time during the tracking process. A complete tracking and identification process of the present invention is divided into four stages: overhead crane stationary tracking, overhead crane position identification, dumping action tracking, dumping signal and weight transmission. The present invention can enable the overhead crane logistics tracking system to accurately track the overhead crane dumping action in real time, and precisely locate the dumping position and the weight of the dumped material, thereby promoting the smooth operation of the secondary equipment in each process.

[0076] When it is detected that the corresponding process information and ground steel ladle information do not exist at the position corresponding to the coordinate data, it is determined that the overhead crane does not generate a dumping action at the position corresponding to the coordinate data.
