Description

Technical Field

[0001] The present invention relates to the technical field of coal yard management, and in particular to an intelligent management and control system for a coal yard. Background Art

[0002] In the operation of large-scale thermal power plants, coal yards are the key link in the storage and supply of coal resources, and their management efficiency is directly related to the operating efficiency, economic cost, safety and stability of power plants.

[0003] Traditional coal yard management relies on manual inspections, manual recording and scheduling, and manual establishment of coal yard coal type storage graphics. This method is not only inefficient, but also prone to data errors and safety hazards that are not discovered in a timely manner.

[0004] Therefore, there is an urgent need for an intelligent coal yard management and control system that can optimize the operation process of the coal yard and promptly detect abnormal information in the coal yard. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent management and control system for a coal yard, aiming to solve at least one of the above-mentioned technical problems.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0007] An intelligent management and control system for a coal yard, comprising:

[0008] A coal yard monitoring module is used to obtain coal mine information of each coal storage area in the coal yard, equipment status information and coal yard monitoring information. The coal mine information includes coal mine type, coal mine quality, coal mine inventory and coal storage time. The equipment includes multiple monitoring devices and at least one bucket wheel machine. The coal yard monitoring information includes coal mine surface temperature, coal retaining wall temperature, gas concentration information and image information of each coal storage area.

[0009] An incoming material management module, used to obtain at least one incoming material information, wherein the incoming material information includes incoming material time, transportation time, incoming material weight and coal mine type;

[0010] A feed management module, used to obtain the load information of the unit in a preset time period, and generate coal demand information based on the load information and preset coal use rules, wherein the coal demand information includes coal ratio information;

[0011] A scheduling plan generation module, used to generate a coal unloading strategy based on at least one of the incoming material information, all the coal mine information, all the bucket wheel machine status information and preset coal unloading rules; or,

[0012] Generate a coal extraction strategy based on the coal demand information, all the coal mine information, all the bucket wheel machine status information and preset coal extraction rules;

[0013] A safety monitoring module is used to determine whether there is abnormal information in the coal yard based on all the coal mine information, the status information of each device, and the coal yard monitoring information. If there is abnormal information in the coal yard, corresponding alarm information is generated according to the abnormal information;

[0014] The display module is used to display the coal mine information of each coal storage area, the status information of each equipment, the coal yard monitoring information, the strategy information and the alarm information in a preset coal yard display model, wherein the strategy information includes the coal unloading strategy and the coal taking strategy.

[0015] The beneficial effects of the present invention are as follows: the incoming material management module and the supply management module are responsible for acquiring incoming material information and generating coal demand information respectively. The scheduling plan generation module intelligently generates coal unloading strategies and coal taking strategies according to incoming material information, coal mine information, the bucket wheel machine status information and preset rules. This helps to optimize the operation process of the coal yard and improve operation efficiency.

[0016] The safety monitoring module can detect abnormal information in the coal yard in a timely manner and generate corresponding alarm information by comprehensively analyzing coal mine information, equipment status information and monitoring information. This helps to take timely measures to deal with potential safety hazards and ensure the safe operation of the coal yard. The display module displays various types of information in the preset coal yard display model, including coal mine information, equipment status, monitoring information, coal unloading strategy, coal taking strategy and alarm information. This visual display method enables managers to intuitively understand the overall operation of the coal yard and facilitate more accurate decision-making.

[0017] Based on the above technical solution, the present invention can also be improved as follows.

[0018] Furthermore, the generation process of the coal unloading strategy is:

[0019] Determine the priority of each coal mine in the coal yard based on the coal mine information of each coal storage area and the unit operation information;

[0020] Obtaining a material unloading time period, determining whether there is a plurality of material incoming information within the material unloading time period, and if there is a plurality of material incoming information, determining a first weight of each of the material incoming information according to the priority of various coal mines in the coal yard;

[0021] Determine the second weight of each piece of incoming material information according to the transportation time in each piece of incoming material information;

[0022] Determine the coal unloading priority of each incoming material information based on the first weight and the second weight of each incoming material information;

[0023] The coal unloading strategies are generated in sequence according to the coal unloading priorities of each incoming material information, the coal mine information of each coal storage area and the status information of all bucket wheel machines.

[0024] The beneficial effect of adopting the above further scheme is: by comprehensively considering the priority of each type of coal mine in the coal yard, incoming material information and status information of the bucket wheel excavator, the system can allocate and schedule resources more effectively, ensuring that high-priority and urgently needed coal can be processed first, thereby improving the overall operating efficiency of the coal yard.

[0025] Further, the status information of each bucket wheel machine includes usage information and operating status, the usage information includes tasks to be completed and the estimated time to complete the tasks to be completed, and the process of sequentially generating coal unloading strategies according to the coal unloading priority of each incoming material information, the coal mine information of each coal storage area and the status information of all bucket wheel machines is as follows:

[0026] Step S11, selecting the incoming material information with the highest priority from among the incoming material information within the unloading time period as the incoming material information to be processed, and determining a first target bucket wheel machine that meets the first set bucket wheel machine use condition for the incoming material information to be processed based on the use information and operation status of each bucket wheel machine;

[0027] Step S12, based on the incoming material weight and incoming material type of the incoming material information to be processed, matching at least one coal storage area to be selected that meets a set condition from each of the coal storage areas, wherein the set condition is that the remaining coal storage amount in the coal storage area is greater than the incoming material weight, and the type of the stored coal is the same as the incoming material type;

[0028] Step S13: if there are multiple coal storage areas to be selected, then based on the position of the first target bucket wheel excavator and each coal storage area to be selected, path information of each coal storage area to be selected is generated;

[0029] Step S14, based on the path information of each coal storage area to be selected, the coal storage area to be selected with the shortest path information is selected as the first target coal storage area, and based on the path information of the first target coal storage area and the incoming material weight of the incoming material information to be processed, the use time period of the first target bucket wheel excavator is determined;

[0030] Step S15, based on the target coal storage area, the path information corresponding to the first target coal storage area and the usage time period of the first target bucket wheel excavator, generate a coal unloading strategy, update the incoming material information to be processed to the processed incoming material information, and execute steps S11 to S15 until the coal unloading strategies corresponding to all the incoming material information are generated.

[0031] The beneficial effect of adopting the above further scheme is: by giving priority to the highest priority incoming material information and matching it with the most suitable first target bucket wheel excavator, efficient resource matching is achieved, ensuring that important and urgent incoming materials can be processed quickly, reducing waiting time, and improving overall operating efficiency. When matching the coal storage area, the system not only considers whether the remaining coal storage volume is greater than the incoming material weight, but also ensures that the type of stored coal is the same as the incoming material type, thereby achieving accurate coal storage management. In the case where there are multiple coal storage areas to be selected, the system generates path information for each coal storage area to be selected, and determines a target coal storage area based on this information, thereby achieving optimal path planning. This optimized planning reduces the moving distance and operating time of the bucket wheel excavator and improves coal unloading efficiency.

[0032] Furthermore, the generation process of the coal extraction strategy is as follows:

[0033] Based on the coal usage ratio information, multiple second target coal storage areas that meet the coal extraction conditions are matched from each of the coal storage areas, and the coal extraction quantity and coal extraction type of each of the second target coal storage areas are determined, wherein the coal extraction conditions are that the remaining coal storage quantity in the coal storage area is greater than the coal extraction quantity, the coal mine type in the coal storage area is the same as the coal extraction type, and the priority of the coal storage time in the coal storage area meets the preset priority threshold;

[0034] According to the usage information and status information of all bucket wheel machines, a second target bucket wheel machine that meets the second set bucket wheel machine usage condition is selected;

[0035] Based on the position of the second target bucket wheel machine and each of the second target coal storage areas, generating a coal extraction path;

[0036] Determine the use time of the second target bucket wheel excavator based on the coal taking path and the total amount of coal taken;

[0037] A coal extraction strategy is generated based on the coal extraction path, the coal extraction amount of each of the second target coal storage areas, and the use time of the second target bucket wheel excavator.

[0038] The beneficial effect of adopting the above further scheme is that when matching the coal storage area, not only the type and quality of the coal mine are taken into account, but also the stock and storage time of the coal are taken into account, which helps to achieve the optimal utilization of coal resources. Prioritizing the use of areas with longer coal storage time or more coal storage helps to reduce coal backlog and loss and improve the overall operating efficiency of the coal yard. According to the use information and status information of the bucket wheel machine, the second target bucket wheel machine is reasonably selected for coal extraction operation. This equipment scheduling method ensures the continuous operation and efficient utilization of the bucket wheel machine and reduces the idle and waiting time of the equipment.

[0039] Furthermore, the scheduling plan generating module is also used for:

[0040] After the second target bucket wheel machine takes coal based on the coal taking strategy, obtaining an actual taken coal weight, and judging whether there is an operation deviation based on the actual taken coal weight;

[0041] If there is an operation deviation, an alarm prompt message will be generated, and a new coal extraction strategy will be generated based on the actual coal extraction weight and coal extraction type corresponding to the operation deviation.

[0042] The beneficial effect of adopting the above further scheme is that by obtaining the actual coal weight and comparing it with the planned coal quantity, it is possible to promptly detect whether there is a deviation in the operation process. This real-time feedback mechanism helps to ensure the accuracy of coal extraction operations and avoid the accumulation of errors caused by human or equipment factors. For coal extraction tasks that cannot be completed as planned due to deviations, the system generates a new coal extraction strategy to remedy it, avoiding waste and idleness of resources. At the same time, the new coal extraction strategy can also be optimized and adjusted according to the actual situation of the current coal yard and equipment, further improving resource utilization efficiency.

[0043] Further, when the safety monitoring module determines whether there is abnormal information in the coal yard based on all the coal mine information, the operation information, and the monitoring information, it is specifically used to:

[0044] Based on the surface temperature of the coal mine and the temperature of the coal retaining wall corresponding to each coal storage area, judging whether there is a temperature anomaly in the coal yard, and if there is a temperature anomaly, determining that there is a first anomaly in the coal yard;

[0045] If there is no temperature anomaly, judging whether there is toxic gas in the coal yard based on the gas concentration information of each coal storage area, and if there is toxic gas in the coal yard, determining that there is a second anomaly in the coal yard;

[0046] If there is no poisonous gas, judging whether there is an abnormality in the coal storage time of the coal yard based on the coal storage time corresponding to each coal storage area; if there is an abnormality in the coal storage time, determining that there is a third abnormality in the coal yard;

[0047] If there is no abnormality in the coal storage time, judging whether there is an equipment abnormality in the coal yard based on the status information of each device, and if there is an equipment abnormality, determining that the coal yard has a fourth abnormality;

[0048] If there is no equipment abnormality, it is determined whether there is a coal mine information mismatch abnormality based on the image information, coal unloading strategy and / or coal taking strategy of each coal storage area;

[0049] If there is a coal mine information mismatch anomaly, it is determined that the coal yard has a fifth anomaly;

[0050] If the coal yard has at least one of the first abnormality, the second abnormality, the third abnormality, the fourth abnormality and the fifth abnormality, it is determined that the coal yard has abnormal information.

[0051] The beneficial effect of adopting the above further scheme is: by comprehensively considering multiple aspects of the coal yard, including temperature, gas concentration, coal storage time, equipment operating status, and the matching degree of coal mine information and strategy, comprehensive monitoring and diagnosis of the coal yard is achieved. Abnormal temperature, abnormal toxic gas, etc. may pose a threat to the safety of the coal yard. By real-time monitoring of these parameters and judging whether there are abnormalities, it is possible to effectively prevent the occurrence of safety accidents such as fire and poisoning, and improve the safety of the coal yard. Abnormal coal storage time may mean that some types of coal are overstocked or understocked. By timely judging and adjusting the coal storage strategy, the configuration and utilization efficiency of coal resources can be optimized. Equipment abnormality may affect the temperature of the coal yard, toxic gas detection, bucket wheel positioning and coal panning. By detecting the operating status of the equipment, the adverse effects of equipment failure on the temperature of the coal yard, toxic gas detection, bucket wheel positioning and coal panning can be reduced. By comparing the weight of coal taken or the weight of coal stored with the planned coal quantity information, it is possible to timely discover whether there is a deviation in the operation process.

[0052] Further, when there is abnormal information in the coal yard, the safety monitoring module generates corresponding alarm information according to the abnormal information, specifically for:

[0053] If the abnormal information is a first abnormality, determining a first coal storage area corresponding to the first abnormality, and generating first alarm information according to the position and temperature of the first coal storage area;

[0054] or,

[0055] If the abnormal information is a second abnormality, determining a second coal storage area corresponding to the second abnormality, and generating a second alarm information according to the location of the second coal storage area and the type and concentration of the toxic gas;

[0056] or, if the abnormal information is the third abnormality, determining a third coal storage area corresponding to the third abnormality, and generating third alarm information according to the location and coal storage time of the third coal storage area;

[0057] or, if the abnormal information is a fourth abnormality, determining a target device corresponding to the fourth abnormality, and generating fourth alarm information according to a location of the target device;

[0058] Or, if the abnormal situation is the fifth abnormality, the target incoming material information or the target material demand information corresponding to the fifth abnormality is determined, and the fifth alarm information is generated according to the abnormal matching of the target incoming material information or the target material demand information.

[0059] The beneficial effect of adopting the above further scheme is: by associating different abnormal information with abnormal content and generating corresponding alarm information, relevant personnel can quickly understand the specific location and nature of the abnormal situation, so as to quickly respond and take corresponding treatment measures.

[0060] Furthermore, the security monitoring module is also used for:

[0061] When the alarm information is the first alarm information, a temperature reduction process is performed on the first coal storage area to eliminate the temperature abnormality of the first coal storage area;

[0062] or,

[0063] When the alarm information is a second alarm message, turning on the ventilation equipment corresponding to the second coal storage area to remove the poisonous gas in the second coal storage area;

[0064] or,

[0065] When the alarm information is the third alarm information, priority classification processing is performed based on each coal storage time of the third coal storage area, and the classification result is marked in the coal yard display model corresponding to the third coal storage area;

[0066] or,

[0067] When the alarm information is the fourth alarm information, a maintenance personnel is assigned based on the target device and a preset device maintenance rule to eliminate the device abnormality of the target device;

[0068] or,

[0069] When the warning information is the fifth warning information, the target incoming material information or the target material demand information is marked.

[0070] The beneficial effects of adopting the above further scheme are: through isolation and cooling treatment, the temperature of the first coal storage area can be quickly reduced to prevent the occurrence of safety accidents such as fire; turning on the ventilation equipment can quickly remove the toxic gas in the second coal storage area to ensure the safety of personnel. By prioritizing the coal storage time in the third coal storage area and marking the classification results in the coal yard display model, it helps managers understand the distribution of coal resources and optimize coal extraction strategies. Assigning maintenance personnel based on target equipment and preset equipment maintenance rules can ensure that equipment is repaired in a timely manner and reduce downtime caused by equipment failure. Marking target incoming material information or target material demand information helps managers quickly identify and deal with information mismatch problems.

[0071] Furthermore, the coal yard monitoring module also includes:

[0072] The inventory structure warning submodule is used to determine whether there is an inventory shortage based on the incoming material information, the load information of the unit, the coal mine information of each coal storage area in the coal yard, and the preset inventory structure model; if there is an inventory shortage, generate a warning message;

[0073] The daily report generation submodule summarizes the total amount of coal unloaded and stored at the coal yard based on preset time nodes.

[0074] The beneficial effect of adopting the above further scheme is: by real-time monitoring of incoming material information, unit load information, and coal mine information in each coal storage area within the coal yard, and comparing and analyzing with the preset inventory structure model, it is possible to predict in advance whether there is a risk of inventory shortage. This early warning mechanism helps coal yard managers take timely measures, such as adjusting procurement plans, optimizing coal storage strategies, etc., to effectively prevent the occurrence of inventory shortages. The daily report generation submodule can automatically summarize the total amount of coal unloading and coal storage in the coal yard based on the preset time nodes, reducing the workload of manual statistics and improving work efficiency.

[0075] Furthermore, the display module is specifically used for:

[0076] Establishing a three-dimensional coal yard model and a two-dimensional coal yard model based on each coal storage area;

[0077] According to the relative positions of the coal storage areas, marking area labels corresponding to the coal storage areas in the three-dimensional model of the coal yard and the two-dimensional model of the coal yard;

[0078] The corresponding positions of the regional labels in the three-dimensional model of the coal yard and the two-dimensional model of the coal yard respectively display the current status information of each device, the coal yard monitoring information, the strategy information and the alarm information, and highlight the alarm information and the abnormal information corresponding to the alarm information.

[0079] The beneficial effect of adopting the above further scheme is that by displaying the coal yard through three-dimensional and two-dimensional models, the overall layout of the coal yard and the relative positions of various coal storage areas can be intuitively seen. This intuitive display method helps managers quickly understand the operating status of the coal yard and improve decision-making efficiency. The model not only displays the coal storage area, but also integrates various data such as the operating status information, monitoring information, coal unloading strategy, coal extraction strategy and alarm information of each equipment. This highly integrated display method allows managers to obtain comprehensive information about the coal yard in one stop, reducing the time for information search and comparison. Highlighting the alarm information and corresponding anomalies in the model can quickly attract the attention of managers, enabling them to prioritize important and urgent issues and reduce potential risks.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0084] The present application embodiment provides a coal yard intelligent monitoring system, such as Figure 1 As shown, a coal yard intelligent monitoring system includes:

[0085] The coal yard monitoring module 201 is used to obtain the coal mine information of each coal storage area in the coal yard, the status information of the equipment and the coal yard monitoring information, wherein the coal mine information includes the type of coal mine, the quality of coal mine, the amount of coal mine and the coal storage time, the equipment includes a plurality of monitoring devices and at least one bucket wheel machine, and the coal yard monitoring information includes the surface temperature of the coal mine, the temperature of the coal retaining wall, the gas concentration information and the image information of each coal storage area;

[0086] In the implementation mode of the present application, a 3D modeling system is used to fuse and process various laser scanning signals to generate volume signals of partitioned material piles, which are sent to the coal counting system. The coal counting system associates the coal type density data and calculates the mass of coal stored in each coal storage area. The weight of materials entering and leaving each coal storage area is counted by weighing and counting the materials, thereby obtaining the coal stock in each coal storage area of ​​the coal yard.

[0087] The monitoring equipment includes multiple temperature sensors, gas concentration sensors, image acquisition equipment, positioning equipment, bucket wheel excavator current detection equipment, material level detection equipment, contour scanner, etc. The positioning equipment includes RFID radio frequency tags and UWB vehicle-mounted tags, etc. The coal yard monitoring module records the location of each monitoring device and stores the monitoring data sent by each monitoring device, and determines the status information of each corresponding device based on the monitoring data.

[0088] The incoming material management module 202 is used to obtain at least one incoming material information, wherein the incoming material information includes the incoming material time, the transportation time, the incoming material weight and the incoming material type;

[0089] In the implementation mode of the present application, the incoming material management module includes pages such as car unloading, train unloading (including rollover), and receiving performance viewing. The above pages are used to enter or scan and obtain key information such as incoming material time, transportation time, incoming material weight, incoming material type (such as coal type, quality grade), etc.

[0090] The feed management module 203 is used to obtain the load information of the unit in a preset time period, and generate coal demand information based on the load information and the preset coal use rules, wherein the coal demand information includes coal ratio information, type and quality of each coal mine;

[0091] In the implementation manner of the present application, the feed management module 203 is connected to the unit monitoring system interface to obtain the load information of the unit in real time or periodically.

[0092] Using historical data and time series analysis methods for a preset time period, the load of the unit in the future preset time period is predicted, and coal demand information is generated based on the predicted load and preset coal use rules. The preset coal use rules are formulated by experts based on historical unit load conditions and historical coal use conditions, as well as empirical data on key indicators such as coal calorific value, ash content, sulfur content, and volatile matter. Coal use rules include but are not limited to coal type selection, ratio calculation, coal quality requirements, etc.

[0093] A scheduling plan generation module 204 is used to generate a coal unloading strategy based on at least one of the incoming material information, all of the coal mine information, all of the bucket wheel machine status information and preset coal unloading rules; or,

[0094] Generate a coal extraction strategy based on the coal demand information, all the coal mine information, all the bucket wheel machine status information and preset coal extraction rules;

[0095] In the implementation manner of the present application, the generation process of the coal unloading strategy is:

[0096] First, based on the coal mine information of each coal storage area and the unit operation information, the priority of each type of coal mine in the coal yard is determined. Specifically, the coal demand information required for a future time period is calculated through the unit operation information, and the urgency of the required coal mine type is determined according to the coal demand information and the coal storage amount of each coal storage area, and the priority of each type of coal mine in the coal yard is determined according to the urgency of the required coal mine type.

[0097] Afterwards, the unloading time period is obtained to determine whether there are multiple incoming material information within the unloading time period. The incoming material type in the incoming material information is associated with the coal mine type. If there are multiple incoming material information, the first weight of each incoming material information is determined according to the priority of various coal mine types in the coal yard. The incoming material information corresponding to the coal mine type with a high priority will obtain a higher first weight.

[0098] Afterwards, according to the transportation time in each of the incoming material information, the second weight of each of the incoming material information is determined. The longer the transportation time, the more likely it is to cause safety problems. Therefore, the longer the transportation time, the higher the second weight.

[0099] Then, based on the first weight and the second weight of each incoming material information, the coal unloading priority of each incoming material information is determined;

[0100] Finally, the coal unloading strategies are generated in sequence according to the coal unloading priorities of the incoming material information, the coal mine information of each coal storage area and the status information of all bucket wheel machines.

[0101] If it does not exist, the coal unloading strategy will be generated directly based on the single incoming material information.

[0102] In the implementation manner of the present application, the status information of the bucket wheel machine includes usage information and operating status. The usage information includes tasks to be completed and the estimated time to complete the tasks to be completed. The operating status includes whether it is idle, current location, working capacity, etc.

[0103] The process of generating the coal unloading strategy in sequence according to the coal unloading priority of each incoming material information, the coal mine information of each coal storage area and the status information of the bucket wheel machine is as follows:

[0104] Step S11, among various incoming material information within the unloading time period, select the incoming material information with the highest priority as the incoming material information to be processed, and determine the first target bucket wheel machine that meets the first set bucket wheel machine use condition for the incoming material information to be processed based on the use information and operation status of each bucket wheel machine, and the first set bucket wheel machine use condition is: based on the status information of all bucket wheel machines, determine whether there is a bucket wheel machine in an idle state, if so, determine the first target bucket wheel machine based on the position of each bucket wheel machine in the idle state, if not, select the bucket wheel machine with the shortest estimated time to complete the task to be completed as the first target bucket wheel machine based on the use information of all bucket wheel machines;

[0105] Step S12, based on the incoming material weight and incoming material type of the incoming material information to be processed, matching at least one coal storage area to be selected that meets a set condition from each of the coal storage areas, wherein the set condition is that the remaining coal storage amount in the coal storage area is greater than the incoming material weight, and the type of the stored coal is the same as the incoming material type;

[0106] Step S13, if there are multiple coal storage areas to be selected, then based on the position of the first target bucket wheel excavator and each coal storage area to be selected, generate path information of each coal storage area to be selected; in the implementation mode of the present application, Dijkstra algorithm, A* algorithm, etc. can be used for path planning.

[0107] Step S14, based on the path information of each coal storage area to be selected, the coal storage area to be selected with the shortest path information is selected as the first target coal storage area, and based on the path information of the first target coal storage area and the incoming material weight of the incoming material information to be processed, the use time period of the first target bucket wheel excavator is determined;

[0108] Step S15, based on the target coal storage area, the path information corresponding to the first target coal storage area and the usage time period of the first target bucket wheel excavator, generate a coal unloading strategy, update the incoming material information to be processed to the processed incoming material information, and execute steps S11 to S15 until the coal unloading strategies corresponding to all the incoming material information are generated.

[0109] After the coal unloading strategy is generated, it is sent to the staff of the bucket wheel machine for confirmation. After the staff confirms it, the bucket wheel machine unloads the coal according to the coal unloading strategy.

[0110] In the implementation manner of the present application, the generation process of the coal extraction strategy is:

[0111] Based on the coal usage ratio information, multiple second target coal storage areas that meet the coal extraction conditions and the coal extraction quantity and coal extraction type of each second target coal storage area are matched from each of the coal storage areas, wherein the coal extraction conditions are that the remaining coal storage quantity in the coal storage area is greater than the coal extraction quantity, the coal mine type in the coal storage area is the same as the coal extraction type, and the priority of the coal storage time in the coal storage area meets the preset priority threshold;

[0112] According to the usage information and status information of all bucket wheel machines, a second target bucket wheel machine that meets the second set bucket wheel machine usage condition is selected; the second set bucket wheel machine usage condition is: based on the status information of the bucket wheel machine, it is judged whether there is a bucket wheel machine in an idle state; if so, the second target bucket wheel machine is determined based on the position of each bucket wheel machine in an idle state and the position of each second target coal storage area; if not, based on the usage information of all bucket wheel machines, the bucket wheel machine with the shortest estimated time to complete the task to be completed is selected as the second target bucket wheel machine;

[0113] Based on the position of the second target bucket wheel machine and each of the second target coal storage areas, generating a coal extraction path;

[0114] Determine the use time of the second target bucket wheel excavator based on the coal taking path and the total amount of coal taken;

[0115] A coal taking strategy is generated based on the coal taking path, the coal taking amount of each of the second target coal storage areas, and the use time of the second target bucket wheel excavator.

[0116] In the implementation mode of the present application, first, matching is performed based on coal ratio information (such as unit load, coal type demand, calorific value requirement, coal quantity demand, etc.) and the coal type, coal quality, and coal stock in each coal storage area.

[0117] When multiple coal storage areas of the same type of coal are matched and all meet the coal quantity demand, calorific value requirements and unit load, the coal storage area with a longer storage time is selected as the second target coal storage area. After that, the actual use information and status information of the bucket wheel machine are queried, and the second target bucket wheel machine that performs the coal taking task is selected according to the actual use information and status information of the bucket wheel machine. After that, based on the current position of the second target bucket wheel machine and the position of the second target coal storage area, the path planning algorithm (such as Dijkstra algorithm, A* algorithm, etc.) is used to generate the optimal coal taking path, and the use time of the second target bucket wheel machine is determined according to the coal taking path, the total amount of coal taken and the working efficiency of the second bucket wheel machine of the bucket wheel machine. Finally, the second target coal storage area, coal taking amount, coal taking type, second target bucket wheel machine, coal taking path and use time determined in the above steps are integrated to generate a detailed coal taking strategy.

[0118] When matching coal storage areas, not only the type and quality of coal mines are taken into account, but also the stock and storage time of coal are taken into account, which helps to achieve the optimal utilization of coal resources. Prioritizing the use of areas with longer coal storage time or larger coal storage helps to reduce coal backlog and loss and improve the overall operating efficiency of the coal yard. According to the use information and status information of the bucket wheel machine, the second target bucket wheel machine is reasonably selected for coal extraction operations. This equipment scheduling method ensures the continuous operation and efficient utilization of the bucket wheel machine and reduces the idle and waiting time of the equipment.

[0119] The scheduling plan generation module is also used for:

[0120] After the second target bucket wheel machine takes coal based on the coal taking strategy, obtaining an actual taken coal weight, and judging whether there is an operation deviation based on the actual taken coal weight;

[0121] If there is an operation deviation, an alarm prompt message will be generated, and a new coal extraction strategy will be generated based on the actual coal extraction weight and coal extraction type corresponding to the operation deviation.

[0122] In the implementation mode of the present application, after the second target bucket wheel machine completes the coal extraction operation according to the coal extraction strategy, the actual coal extraction weight is obtained through the weighing system or other metering equipment of the bucket wheel machine, and the difference between the actual coal extraction weight and the target coal extraction amount, i.e., the operation deviation, is calculated. The deviation is judged whether it is within the acceptable range according to the preset deviation threshold. If the deviation exceeds the threshold, it is considered that there is an operation deviation, and the scheduling plan generation module should automatically generate an alarm prompt information, which should include the specific value of the operation deviation, the coal storage area where the deviation occurs, the bucket wheel machine number, the timestamp and other key information. Then, the operation deviation is analyzed according to the deviation and monitoring information, and the cause of the deviation is analyzed.

[0123] Afterwards, based on the deviation of coal weight and type, combined with the current coal yard inventory, unit coal demand and bucket wheel machine availability, a new coal strategy is generated. The new coal strategy should make compensatory adjustments for the deviation to ensure that the final total amount of coal meets the coal demand.

[0124] By obtaining the actual coal weight and comparing it with the planned coal weight, it is possible to promptly detect any deviations in the operation process. This real-time feedback mechanism helps ensure the accuracy of coal extraction operations and avoids the accumulation of errors caused by human or equipment factors.

[0125] The safety monitoring module 205 is used to determine whether there is abnormal information in the coal yard based on all the coal mine information, the status information of each device, and the coal yard monitoring information. If there is abnormal information in the coal yard, corresponding alarm information is generated according to the abnormal information; wherein the alarm information is used to send the alarm information to the management terminal corresponding to the coal yard, so as to warn the management personnel through the management terminal;

[0126] In the implementation manner of the present application, when the safety monitoring module determines whether there is abnormal information in the coal yard based on all the coal mine information, the operation information, and the monitoring information, it is specifically used to:

[0127] Step S21, based on the surface temperature of the coal mine and the temperature of the coal retaining wall corresponding to each coal storage area, determine whether there is a temperature abnormality in the coal yard. If there is a temperature abnormality, proceed to step S22 to determine whether there is a first abnormality in the coal yard; if there is no temperature abnormality, proceed to step S22;

[0128] In the implementation manner of the present application, for any coal storage area, the surface temperature of the coal mine corresponding to the coal storage area is compared with a preset first temperature threshold. If the surface temperature of the coal mine is greater than the first temperature threshold, it is determined that the temperature of the coal stored in the coal yard is abnormal.

[0129] For any coal storage area, the temperature of the coal retaining wall corresponding to the coal storage area is compared with a preset second temperature threshold. If the temperature of the coal retaining wall is greater than the second temperature threshold, it is determined that the coal storage temperature of the coal yard is abnormal.

[0130] Step S23, based on the gas concentration information of each coal storage area, determine whether there is toxic gas in the coal yard. If there is toxic gas in the coal yard, proceed to step S23 to determine whether there is a second abnormality in the coal yard; if there is no toxic gas, proceed to step S24.

[0131] In the implementation manner of the present application, for any coal storage area, if toxic gas exists in the detected gas and the concentration of the toxic gas is greater than a preset concentration threshold, it is determined that there is a toxic gas anomaly in the coal yard.

[0132] Step S24, based on the coal storage time corresponding to each coal storage area, determine whether there is any abnormality in the coal storage time of the coal yard. If there is any abnormality in the coal storage time, proceed to step S25 to determine whether there is a third abnormality in the coal yard; if there is no abnormality in the coal storage time, proceed to step S26.

[0133] In the present implementation mode, the time threshold corresponding to each coal mine is determined according to the type of each coal mine. For any coal storage area, a preset time threshold is determined according to the type of coal mine stored in the coal storage area, and the corresponding coal storage time in the coal storage area is compared with the time threshold. If the coal storage time is greater than the time threshold, it is determined that there is an abnormal coal storage time in the coal yard.

[0134] Step S26, judging whether there is any equipment abnormality in the coal yard based on the status information of each device, if there is any equipment abnormality, proceeding to step S27, determining whether there is a fourth abnormality in the coal yard; if there is no equipment abnormality, proceeding to step S28.

[0135] In the implementation manner of the present application, different devices have different ways of judging abnormalities. For example, for temperature sensors, gas concentration sensors, image acquisition devices, etc., it is necessary to determine whether there is an abnormality based on the operation of each sensor. If the above device stops data acquisition, it is determined that there is a device abnormality.

[0136] For positioning tag devices, it is necessary to determine whether there is an abnormality based on the power level of each tag. If the power level of the tag exceeds the first preset power threshold, it is determined that there is a device abnormality, so that the staff can charge the tag in time.

[0137] Step S28, judging whether there is a coal mine information mismatch anomaly based on the image information, coal unloading strategy and / or coal taking strategy of each coal storage area; if there is a coal mine information mismatch anomaly, determining that the coal yard has a fifth anomaly;

[0138] Step S29: If the coal yard has the first abnormality, the second abnormality, the third abnormality, the fourth abnormality and the fifth abnormality, it is determined that the coal yard has abnormal information.

[0139] In an implementation manner of the present application, when the bucket wheel excavator starts to execute a coal unloading strategy or a coal taking strategy, the collected images of each coal storage area are preprocessed, and the preprocessed images are identified and analyzed using image processing technology and machine learning algorithms to extract the shape, color, texture and other features of the coal pile in the coal storage area. The extracted features are compared with the corresponding coal unloading strategy or coal taking strategy. If, during the image recognition and analysis process, it is found that there are significant differences between the coal pile features of the coal storage area and the coal unloading strategy or coal taking strategy, such as inconsistency in coal type, changes in coal quality, etc., then it is judged as an abnormal coal mine information mismatch.

[0140] By comprehensively considering multiple aspects of the coal yard, including temperature, gas concentration, coal storage time, equipment operating status, and the matching degree of coal mine information and strategy, comprehensive monitoring and diagnosis of the coal yard is achieved.

[0141] In the present implementation manner, when the safety monitoring module generates corresponding alarm information according to the abnormal information when there is abnormal information in the coal yard, it is specifically used to:

[0142] If the abnormal information is a first abnormality, determining a first coal storage area corresponding to the first abnormality, and generating first alarm information according to the position and temperature of the first coal storage area;

[0143] or, if the abnormal information is a second abnormality, determining a second coal storage area corresponding to the second abnormality, and generating second alarm information according to the location of the second coal storage area and the type and concentration of toxic gas;

[0144] or, if the abnormal information is the third abnormality, determining a third coal storage area corresponding to the third abnormality, and generating third alarm information according to the location and coal storage time of the third coal storage area;

[0145] or, if the abnormal information is a fourth abnormality, determining a target device corresponding to the fourth abnormality, and generating fourth alarm information according to a location of the target device;

[0146] Or, if the abnormal situation is the fifth abnormality, the target incoming material information or the target material demand information corresponding to the fifth abnormality is determined, and the fifth alarm information is generated according to the abnormal matching of the target incoming material information or the target material demand information.

[0147] By associating different abnormal information with abnormal content and generating corresponding alarm information, relevant personnel can quickly understand the specific location and nature of the abnormal situation, so as to respond quickly and take corresponding treatment measures.

[0148] In the implementation manner of the present application, the security monitoring module is also used to:

[0149] When the alarm information is the first alarm information, a temperature reduction process is performed on the first coal storage area to eliminate the temperature abnormality of the first coal storage area;

[0150] or, when the alarm information is a second alarm message, turning on the ventilation equipment corresponding to the second coal storage area to remove the poisonous gas in the second coal storage area;

[0151] or, when the alarm information is the third alarm information, priority classification processing is performed based on each coal storage time of the third coal storage area, and the classification result is marked in the coal yard display model corresponding to the third coal storage area;

[0152] or, when the alarm information is the fourth alarm information, a maintenance personnel is assigned based on the target device and a preset device maintenance rule to eliminate the device abnormality of the target device;

[0153] Or, when the alarm information is the fifth alarm information, the target incoming material information or the target material demand information is marked.

[0154] The display module 206 is used to display the coal mine information of each coal storage area, the operation status information of each equipment, the monitoring information, the coal unloading strategy, the coal taking strategy and the alarm information in the preset coal yard display model.

[0155] In the implementation manner of the present application, the display module 206 is specifically used for:

[0156] Establishing a three-dimensional coal yard model and a two-dimensional coal yard model based on each coal storage area;

[0157] According to the relative positions of the various coal storage areas, regional labels corresponding to the coal storage areas are marked in the three-dimensional model of the coal yard and the two-dimensional model of the coal yard; specifically, according to the actual layout of the coal yard and the division of the coal storage areas, the boundaries and names of various coal storage areas are marked in the two-dimensional plan and the three-dimensional model, and different colors or patterns are used to distinguish different coal storage areas, and corresponding regional labels are added next to each area.

[0158] The corresponding positions of the regional labels in the three-dimensional model of the coal yard and the two-dimensional model of the coal yard respectively display the current operating status information, monitoring information, the coal unloading strategy, the coal taking strategy and alarm information of each equipment, and highlight the alarm information and the abnormalities corresponding to the alarm information.

[0159] In the implementation mode of the present application, the operation status information of each device (such as running, stopped, faulty, etc.) is displayed in the corresponding positions of the three-dimensional model and the two-dimensional model through text labels, icons or color changes; the current coal unloading strategy and coal collection strategy are marked in the model, including information such as coal unloading location and coal collection sequence. For alarm information, it is highlighted with eye-catching colors or icons, and the alarm description and disposal suggestions are attached.

[0160] By displaying the coal yard in 3D and 2D models, you can intuitively see the overall layout of the coal yard and the relative positions of various coal storage areas. This intuitive display method helps managers quickly understand the operating status of the coal yard and improve decision-making efficiency.

[0161] Optionally, the coal yard monitoring module 201 further includes:

[0162] The inventory structure warning submodule is used to determine whether there is an inventory shortage based on the incoming material information, the load information of the unit, the coal mine information of each coal storage area in the coal yard, and the preset inventory structure model; if there is an inventory shortage, generate a warning message;

[0163] The daily report generation submodule summarizes the total amount of coal unloaded and stored at the coal yard based on preset time nodes.

[0164] In the implementation mode of the present application, a preset inventory structure model is used to evaluate whether the current inventory can meet the power production demand in the future. The model is obtained based on the analysis of historical coal usage and historical unit load information.

[0165] If the analysis results show that there is a risk of inventory shortage (such as the inventory of a certain key type of coal is below the safety threshold, the overall inventory is insufficient to support production demand in the next few days, etc.), the early warning mechanism will be triggered. The early warning information will be notified to relevant personnel, including coal yard managers, procurement departments, production planning departments, etc., through the system interface, SMS, email and other methods, so that timely measures can be taken to replenish inventory or adjust production plans.

[0166] After summarizing the total amount of coal unloading and coal storage in the coal yard, the daily report generation submodule generates a brief report on the daily coal consumption of the coal yard, including information such as the total amount of coal unloading, total amount of coal storage, distribution of various types of coal, inventory change trend, etc. After that, the generated brief report is automatically sent to relevant personnel such as coal yard managers, financial departments, and superior management departments through internal system messages and emails. At the same time, the daily report is archived for future reference to facilitate subsequent data analysis and audit work.

[0167] This system is responsible for acquiring incoming material information and generating coal demand information through the incoming material management module and the supply management module. The scheduling plan generation module intelligently generates coal unloading and coal taking strategies based on incoming material information, coal mine information, bucket wheel machine status information and preset rules. This helps to optimize the operation process of the coal yard and improve operation efficiency.

[0168] The safety monitoring module comprehensively analyzes coal mine information, equipment status information, and monitoring information, and can promptly detect abnormal information in the coal yard and generate corresponding alarm information. This helps to take timely measures to deal with potential safety hazards and ensure the safe operation of the coal yard. The display module displays various types of information in the preset coal yard display model, including coal mine information, equipment status, monitoring information, coal unloading strategy, coal taking strategy, and alarm information. This visual display method enables managers to intuitively understand the overall operation of the coal yard and facilitate more accurate decision-making.

[0169] When the modules in the device can be implemented in the form of a processing element scheduling program, the processing element can be a general-purpose processor, such as a central processing unit (CPU) or other processor that can call a program. For another example, these modules can be integrated together and implemented in the form of a system-on-a-chip (SOC).
