[0003] At present, the existing automatic loading control method of coal loading is carried out at multiple loading stations, and each station sets a fixed coal loading car for loading according to a preset plan. However, in actual applications, since the fixed coal loading allocation mode cannot be dynamically adjusted according to sudden demand changes and uneven supply between loading stations, only using a fixed loading strategy often easily causes delays in coal loading, resulting in low efficiency of automatic loading control of coal loading.

[0014] The present application embodiment provides a method for controlling automatic loading of coal into a car. In one embodiment, please refer to Figure 1 , Figure 1 The present invention provides a flow chart of the automatic loading control method for coal loading provided by the embodiment of the present invention. The method can be implemented by a computer program, which can be integrated into an application or run as an independent tool application. The method can also be implemented by a single-chip microcomputer or run on an automatic loading control system for coal loading based on the von Neumann system. Specifically, the method can include the following steps: Step 101: Obtain information on coal to be loaded at multiple loading stations and information on coal loading queues corresponding to each loading station.

[0015] Among them, the information on coal to be loaded refers to the coal supply plan information of each loading station within the planning period. In the embodiment of the present application, it can be understood as data such as the type of coal and the planned amount of coal available for each loading station, which is used to reflect the coal shipping demand of each loading station within a given time.

[0016] Coal loading queue information refers to data reflecting the current coal loading and processing status of each loading station. In the embodiment of the present application, it can be understood as information such as the number of coal loading cars that have reached the waiting state and are being loaded at each loading station, which is used to determine the current coal loading and processing capacity of each loading station.

[0017] The loading station refers to the operating area of ​​the coal truck where coal is loaded. In the embodiment of the present application, it can be understood as the loading point of a coal mine or warehouse, which is used to obtain the coal supply and loading information of the loading station, calculate the expected loading quantity and the current coal loading quantity, so as to determine the loading saturation state and formulate a coal loading scheduling plan.

[0018] Specifically, in order to realize the intelligent scheduling of coal loading, it is necessary to obtain the coal supply information of the loading station and the current loading situation of the station in real time. This step will obtain the coal information to be loaded at each loading station within the planning period from the enterprise's coal supply chain management system, including the type of coal to be shipped at this station, the planned amount of coal to be supplied, the shipping destination, the planned shipping time, etc. These coal information to be loaded reflects the coal shipping demand of each station. At the same time, this step will also obtain the coal loading queue information corresponding to each loading station from the enterprise's coal loading scheduling and monitoring system, including the number of coal loading cars that have reached the waiting state, the number of coal loading cars being loaded, the average coal loading time of a single car, the number of available coal loaders, etc. This information reflects the current loading processing capacity of each station. By obtaining the coal supply information and processing capacity information of the loading station, the coal shipping demand and current loading situation of each station can be fully understood, which lays the foundation for the subsequent intelligent scheduling of coal loading according to the real-time coal supply and demand of the loading station.

[0019] Step 102: Based on the coal type and coal supply in the information of each coal to be loaded, determine the expected loading quantity of each loading station, and based on the coal loading queue information, determine the current coal loading quantity of each loading station.

[0020] Among them, coal type refers to the category of different types of coal. In the embodiment of the present application, it can be understood as coal types with different uses such as anthracite and coking coal, which is used to determine the maximum safe loading capacity of a single truck for coal loading.

[0021] The coal supply refers to the amount of coal available for shipment at each loading station within a given planning period. In the embodiment of the present application, it can be understood as the planned coal supply data of each loading station, which is used to calculate the expected loading quantity of each loading station.

[0022] The estimated loading quantity refers to the number of coal loadings required at the loading station within a given planning period, calculated based on the coal supply at the loading station. In the embodiment of the present application, it can be understood as the planned coal loading quantity determined by the type of coal and the supply quantity, which is used to compare with the current coal loading quantity to determine whether there is an imbalance in the loading capacity of the loading station.

[0023] The number of coal loadings refers to the number of coal loadings that are currently being loaded or waiting to be loaded at each loading station. In the embodiment of the present application, it can be understood as the current coal loading processing capacity of the loading station, which is used to compare with the expected loading number of the station to determine whether there is excess or insufficient loading capacity at the loading station.

[0024] Specifically, after obtaining the information of the coal to be loaded and the coal loading queue information of each loading station, it is necessary to calculate the expected loading quantity and the current coal loading quantity of each loading station based on this information. The expected loading quantity is determined based on the information of the coal to be loaded at each station, that is, the type of coal and the planned coal supply. Query the preset loading rate mapping table, and determine the maximum safe loading capacity corresponding to a single vehicle according to the type of coal at each station; then, combined with the planned coal supply, the maximum safe loading capacity is divided by the planned coal supply to calculate the expected loading quantity for each loading station. This reflects the loading demand of each station. The current coal loading quantity is determined based on the coal loading queue information of each station, that is, the sum of the number of coal loading vehicles that have arrived and the number of coal loading vehicles that are being loaded, reflecting the current loading processing capacity of each station. By calculating the expected loading quantity and the current coal loading quantity, it is possible to determine whether there is excess or insufficient loading capacity at each loading station. This provides a basis for subsequent allocation of coal loading according to loading demand, achieves a dynamic balance between coal loading capacity and demand, improves the utilization efficiency of coal loading, and achieves the optimization effect of automatic loading control of coal loading.

[0025] Based on the above embodiment, as an optional embodiment, in step 102: determining the estimated loading quantity of each loading station based on the coal type and coal supply in the information of each coal to be loaded, this step may also include the following steps: Step 201: Determine the maximum safe loading capacity of each coal type corresponding to a single coal loading vehicle in a preset loading rate mapping table.

[0026] Among them, the preset loading rate mapping table refers to a data table that stores the maximum safe loading capacity of different types of coal under specified vehicle models. In the embodiment of the present application, it can be understood as a database that stores the correspondence between coal types and the maximum loading capacity of a single vehicle, which is used to quickly query and obtain the standard maximum loading capacity of various types of coal under a given coal loading model.

[0027] The maximum safe loading capacity of a single coal truck refers to the maximum load weight of a certain type of coal truck that can be achieved for a given type of coal under the premise of ensuring transportation safety. In the embodiment of the present application, it can be understood as the upper limit of the coal weight that can be safely loaded by a coal transport vehicle with specified parameters for a specific type of coal. It is used to calculate the expected one-way loading capacity of each loading station under standard vehicle conditions, and then determine the overall loading times of the station, that is, the expected loading quantity.

[0028] Specifically, in order to calculate the standardized expected loading quantity for each loading station, it is necessary to first determine the maximum safe loading capacity of a single vehicle corresponding to different types of coal under the given coal loading model conditions. Due to the differences in physical properties such as density and porosity of different types of coal, such as anthracite and expanded coal, the maximum safe loading capacity of different types of coal under the same vehicle model and load is also different. In order to quickly and standardizedly obtain this key data, this step presets a loading rate mapping table, which comprehensively considers factors such as the parameters of different types of coal and the restrictions of a given vehicle model, and gives the matching maximum safe loading capacity of different types of coal under the specified vehicle model. In this way, after obtaining the specific coal type reported by the loading station, the corresponding maximum safe loading capacity value can be directly found in the mapping table, without the need to calculate and set standards for each type of coal separately, which improves the efficiency of obtaining the loading capacity. After obtaining this standard maximum loading capacity, the expected number of loadings corresponding to the loading demand of the station, that is, the expected loading quantity, can be quickly calculated, providing a basis for formulating the coal loading scheduling plan.

[0029] Step 202: Calculate the expected loading quantity at each loading station based on the coal supply and the maximum safe loading quantity of a single coal loading vehicle corresponding to each coal type.

[0030] Specifically, in order to obtain the standardized number of loadings within the planning cycle of each loading station, that is, the expected number of loadings, this step will calculate the expected number of loadings for each station based on the maximum safe loading capacity. First, refer to the data stored in the preset loading rate mapping table, and find out the maximum safe loading capacity of a single vehicle of the coal type under the existing coal loading model according to the coal type reported by the loading station. Then, divide the standard maximum safe loading capacity by the coal supply of the loading station within the planning cycle to obtain the number of coal loadings required to complete the corresponding demand of the loading task within the time range, that is, the expected number of loadings for the loading station. Through this calculation and standardization processing, the influence of changes in conditions such as vehicle type and coal type on the expected number of loadings can be eliminated, and the standard number of loadings reflecting the loading demand can be quickly obtained.

[0031] Based on the above embodiment, as an optional embodiment, in step 102: determining the current coal loading quantity of each loading station based on the coal loading queue information, this step may also include the following steps: Step 203: According to the coal loading queue information, determine the number of coal loading cars currently in a waiting state and the number of coal loading cars currently in a loading state at each loading station.

[0032] Specifically, the coal loading queue information of each loading station is collected. This information is obtained through the vehicle positioning system and loading process monitoring system of the station, reflecting the coal loading processing status of the loading station at each moment. Among them, the number of coal loading cars in the waiting state reflects the current stockpiling and backlog of cars to be loaded at the station; the number of coal loading cars in the state of coal loading reflects the current coal loading processing capacity of the station. By counting the number of coal loading cars waiting to be loaded and the number of coal loading cars being loaded at each loading station, the total number of coal loading cars at the station at the current moment can be obtained, reflecting the coal loading processing capacity of the station.

[0033] Step 204: Add the number of coal loading cars currently in the waiting state and the number of coal loading cars in the loading state at each loading station to obtain the current number of coal loading cars at each loading station.

[0034] Specifically, in order to fully reflect the current coal loading and processing capacity of each loading station, it is necessary to combine the number of coal loading cars waiting to be loaded and the number of coal loading cars being loaded at the station. After obtaining the data on the current number of coal loading cars waiting to be loaded and the number of coal loading cars being loaded at each loading station, add the two together to obtain the total number of coal loading cars at the loading station at the current moment. Among them, the number of coal loading cars waiting to be loaded reflects the current backlog and spare capacity of the loading processing at the station, and the number of loading cars being loaded reflects the loading processing capacity of the station. Adding the two together can fully consider the actual loading processing situation of the station, reflecting the total number of coal loading cars and loading throughput of the station in the current period, which more comprehensively describes the current coal loading processing volume and processing capacity of the loading station.

[0035] Step 103: According to the estimated loading quantity and coal loading quantity of each loading station, determine a plurality of first stations to be transferred from coal loading and a plurality of second stations to be allocated for coal loading in each loading station.

[0036] Among them, the first site refers to a loading site where the expected loading quantity is significantly smaller than the current coal loading quantity. In the embodiment of the present application, it can be understood as a loading site with excess coal loading. It is used to identify sites that need to transfer some coal loading to achieve reasonable redistribution of vehicles.

[0037] The second site refers to a loading site where the expected loading quantity is significantly greater than the current coal loading quantity. In the embodiment of the present application, it can be understood as a loading site where there is insufficient coal loading. It is used to identify sites that need to allocate additional coal loading to achieve reasonable reallocation of vehicles.

[0038] Specifically, in order to optimize the allocation of coal loading and eliminate the unbalanced loading capacity between the loading stations, it is necessary to determine the first station with excess vehicles and the second station with insufficient vehicles. First, the expected loading quantity of each loading station is obtained, that is, the loading demand calculated according to the coal supply, and the current coal loading quantity of each station is obtained, that is, the number of vehicles reflecting the actual loading processing capacity. Then, after comparing the two, if the current coal loading quantity of a loading station is significantly more than the expected quantity, it is judged that the station has an excess coal loading state and is determined as the first station to be dispatched. On the contrary, if the current coal loading quantity of the station is much less than the expected quantity, it is determined as the second station to be allocated vehicles. By identifying the first station and the second station, a corresponding coal loading scheduling plan can be formulated, that is, the vehicle units are allocated from the excess vehicles of the first station to the second station to meet the loading needs of these stations, eliminate the unbalanced loading capacity, and achieve the optimal use of vehicles.

[0039] Based on the above embodiment, as an optional embodiment, in step 103: according to the expected loading quantity and the coal loading quantity of each loading station, a plurality of first stations to be transferred from each loading station and a plurality of second stations to be allocated for coal loading are determined. This step may also include the following steps: Step 301: The ratio between the coal loading quantity at each loading station and the expected loading quantity is taken as the loading saturation.

[0040] Among them, loading saturation refers to the ratio of the current number of coal loadings at the loading station to the expected number of loadings. In the embodiment of the present application, it can be understood as a quantitative indicator reflecting the degree of matching between the loading processing capacity of the loading station and the loading demand. It is used to intuitively judge whether there is excess or insufficient loading capacity at each loading station, and serves as the basis for formulating coal loading scheduling plans.

[0041] Specifically, in order to judge the loading situation of each loading station, it is necessary to quantify the loading saturation state of the station. This step compares the current coal loading quantity of each loading station with the expected loading quantity, and calculates their ratio, that is, the current coal loading quantity / expected loading quantity, as the loading saturation measurement indicator of the loading station. Among them, the current coal loading quantity reflects the loading processing capacity of the station, and the expected loading quantity reflects the loading demand. The ratio of the two is the loading saturation. The larger the value, the more abundant the loading capacity, and the smaller the value, the less sufficient the loading capacity. By calculating the loading saturation of each loading station, it can be sorted according to the saturation. Stations with low saturation are arranged to allocate coal loading first, and stations with high saturation are considered to transfer coal loading. In this way, the loading situation of each station can be judged intuitively, and a targeted coal loading scheduling strategy can be formulated.

[0042] Step 302: Compare the loading saturation of each loading station with the loading saturation threshold; when there is a loading station whose loading saturation is greater than or equal to the loading saturation threshold, the loading station is determined as the first station to be transferred for coal loading.

[0043] Specifically, in order to use the loading saturation to determine whether there is excess coal loading at each loading station, it is necessary to set a loading saturation threshold as a judgment standard. After calculating the loading saturation of each loading station, this step compares the loading saturation of each station with the preset loading saturation threshold. Here, the loading saturation threshold can be predetermined according to the actual situation, for example, set to 1.2. If the loading saturation of a loading station is greater than or equal to the threshold of 1.2, it can be determined that the station has a serious excess loading capacity. For these loading stations with loading saturation higher than the threshold, this step will directly determine them as the first station, that is, it is determined to be a station that has excess coal loading and needs to be transferred away. The first station is judged by comparing with the threshold, so that the identification standard of the first station is clearer and more quantitative, and the judgment process is also faster and more efficient.

[0044] Based on the above embodiment, as an optional embodiment, in step 302: comparing the loading saturation of each loading station with the loading saturation threshold, before this step, the following steps may also be included: Step 312: Obtain the average loading saturation, benchmark loading saturation and average loading time of each loading station within a preset sampling period; calculate the standard deviation of the average loading saturation.

[0045] Among them, the average loading saturation refers to the arithmetic mean of the loading saturation of all loading stations. In the embodiment of the present application, it can be understood as a comprehensive indicator reflecting the matching situation between the overall loading processing capacity and loading demand of the loading stations in the entire network, which is used to quickly judge the current average loading situation of the loading stations in the entire network.

[0046] The benchmark loading saturation refers to a reasonable reference value of the loading saturation of a loading station obtained based on statistical analysis of historical data. In the embodiment of the present application, it can be understood as an empirical value that reflects the ideal matching state between the loading processing capacity and the loading demand of the loading station. It is used to compare with the actual loading saturation of each loading station to determine whether it is necessary to schedule coal loading for the loading station, thereby guiding the optimal allocation of loading resources.

[0047] Specifically, in order to determine whether it is necessary to start the global coal loading scheduling plan, it is necessary to collect relevant statistical parameters and calculate the standard deviation. This step will count and obtain the three parameters of the average loading saturation, benchmark loading saturation, and average loading time of all loading stations within the sampling period. Among them, the average loading saturation reflects the loading situation of the entire network, the benchmark loading saturation is a reasonable reference value, and the average loading time reflects the loading efficiency. Then, the standard deviation of the average loading saturation within the sampling period will be calculated. The standard deviation can quantify the fluctuation range and dispersion of the average loading saturation. By obtaining the above statistical parameters and calculating the standard deviation, the current loading and processing status of the loading stations in the entire network can be intuitively and comprehensively reflected, and it can be determined whether there is a systematic imbalance in loading capacity, which provides a basis for deciding whether to start the global scheduling plan.

[0048] Step 322: Determine whether the average loading time is greater than or equal to the loading time threshold; if the average loading time is greater than or equal to the loading time threshold, subtract the standard deviation of the preset multiple from the average loading saturation to obtain the corrected loading saturation threshold.

[0049] Specifically, in order to reasonably determine the loading saturation threshold, the influence of the average loading time needs to be considered. This step will first determine whether the average loading time is greater than or equal to the preset loading time threshold, which can be determined based on historical statistical experience. If the average loading time is greater than or equal to the threshold, it means that the current loading efficiency of the entire network is low. It is necessary to reduce the loading saturation threshold accordingly, that is, subtract several times the standard deviation from the average loading saturation to obtain a lower corrected new loading saturation threshold. Here, the multiple of the standard deviation can be adjusted according to the actual effect, for example, set to 1 or 1.5 times the standard deviation. Subtracting the standard deviation means narrowing the judgment interval range, and the site can be more tolerantly determined as the first site or the second site to deal with inefficiency. If the loading time does not exceed the threshold, the original loading saturation threshold is maintained unchanged. This step allows the setting of the threshold to take into account the impact of loading efficiency, making the determination of the threshold more flexible and reasonable, thereby improving the effect of subsequent loading site differentiation and scheduling scheme formulation.

[0050] Step 332: If the average loading time is less than the loading time threshold, the average loading saturation is increased by a preset multiple of the standard deviation to obtain a corrected loading saturation threshold.

[0051] Specifically, in order to determine the loading saturation threshold, the influence of the average loading time needs to be considered. This step first determines whether the average loading time is less than the preset loading time threshold. If it is less than the threshold, it means that the current loading efficiency of the entire network is relatively high. In this case, it is necessary to increase the loading saturation threshold accordingly, that is, increase the standard deviation by several times on the basis of the average loading saturation to obtain a higher corrected new loading saturation threshold. Here, the multiple of the standard deviation can also be adjusted according to the actual effect, for example, set to 1 or 1.5 times the standard deviation. Increasing the standard deviation means expanding the judgment interval range, and the site can be more strictly judged as the first site or the second site to cope with higher efficiency situations. If the loading time does not exceed the threshold, the original loading saturation threshold is maintained unchanged. This step also takes into account the loading efficiency factor, making the threshold setting more reasonable and improving the effect of distinguishing and scheduling loading sites.

[0052] Step 303: When there is a loading station whose loading saturation is less than the loading saturation threshold, the loading station is determined as the second station to be allocated for coal loading.

[0053] Specifically, in order to use the loading saturation to determine whether there is insufficient coal loading at each loading station, it is necessary to set a loading saturation threshold as a judgment standard. After calculating the loading saturation of each loading station, this step compares the loading saturation of each station with the preset loading saturation threshold. Here, the loading saturation threshold can be predetermined according to actual conditions, for example, set to 0.8. If the loading saturation of a loading station is less than this threshold of 0.8, it can be determined that the station has a serious shortage of loading capacity. For these loading stations whose loading saturation is lower than the threshold, this step will directly determine them as the second station, that is, it is determined to be a station that needs to be allocated due to insufficient coal loading.

[0054] Step 104: Generate a loading strategy in combination with each first site and each second site, and allocate coal loading at each loading site based on the loading strategy.

[0055] Among them, the loading strategy refers to the coal loading scheduling plan including shunting routes, vehicle allocation quantity, etc. determined according to the coal loading processing situation of each loading station. In the embodiment of the present application, it can be understood as an action plan to guide coal loading allocation, which is used to organize and schedule coal loading in a targeted manner after identifying loading stations with excess and insufficient coal loading, so as to achieve a dynamic balance of loading capacity between stations.

[0056] Specifically, after determining the first site and the second site, it is necessary to formulate a corresponding loading strategy for coal loading scheduling. This step will first comprehensively consider the specific conditions of each first site, that is, the site with excess coal loading, and the second site, that is, the site with insufficient coal loading. Then, a scientific and reasonable loading strategy is formulated based on factors such as the coal loading processing demand, transportation distance, and loading efficiency of each site. This strategy includes clarifying the number of coal loadings to be allocated between each site, the vehicle scheduling route, and other contents. Finally, this step will organize and command the allocation of coal loading between relevant sites according to the formulated loading strategy. That is, some coal loading units are transferred from the first site, and are allocated to the second site through the transportation route to meet the loading needs of the second site. Through the coal loading scheduling guided by the loading strategy, the unbalanced loading capacity between the loading sites can be effectively eliminated, and the utilization efficiency of coal loading can be improved.

[0057] Based on the above embodiment, as an optional embodiment, in step 104: combining each first site and each second site to generate a loading strategy, this step may also include the following steps: Step 401: Obtain the number of coal loading cars to be transferred corresponding to each first station, the number of coal loading cars to be allocated corresponding to each second station, and the relative distance between each first station and each second station.

[0058] Among them, the number of coal loading cars to be transferred refers to the first station, that is, the number of coal loading cars that can be allocated to other stations at the station with excess coal loading. In the embodiment of the present application, it can be understood as an important indicator reflecting the degree of excess coal loading processing capacity of the first station, which is used to determine the coal loading scheduling volume that the first station can provide, so as to reasonably formulate the coal loading allocation plan between the stations in the loading strategy.

[0059] The number of coal loading cars to be allocated refers to the second site, that is, the number of additional coal loading cars that are needed at the site with insufficient coal loading. In the embodiment of the present application, it can be understood as an important indicator reflecting the degree of insufficient coal loading processing capacity of the second site, and is used to determine the amount of coal loading scheduling that needs to be increased at the second site, so as to reasonably formulate the coal loading allocation plan between the sites in the loading strategy.

[0060] The relative distance refers to the transportation distance between the first site and the second site. In the embodiment of the present application, it can be understood as an important parameter reflecting the transportation cost and time cost of coal loading and dispatching between the two sites, and is used to optimize the site matching plan when formulating the loading strategy.

[0061] Specifically, in order to formulate a loading strategy, key parameters need to be obtained as support. This step will first count the number of coal loading cars to be transferred from each determined first station, that is, the station with excess coal loading, to reflect the number of coal loading cars that each first station can provide for allocation. At the same time, the number of coal loading cars to be allocated at each second station, that is, the station with insufficient coal loading, is counted to reflect the number of coal loading cars that need to be increased at each second station. In addition, this step will also count the transportation distance between each first station and each second station, that is, the relative transportation distance between the two stations. Obtaining this parameter can clarify the coal loading allocation demand of each station and the spatial position relationship between the stations, which provides key input for the subsequent formulation of a scientific and reasonable loading strategy. This enables the loading strategy to quantitatively guide the coal loading allocation plan and further optimize the utilization efficiency of coal loading.

[0062] Step 402: Based on the number of coal loading cars to be transferred, the number of coal loading cars to be allocated, and the relative distances, each first site and each second site are matched to obtain multiple loading matching results.

[0063] Among them, the loading matching result refers to the site matching solution generated by combining and pairing the first site and the second site. In the embodiment of the present application, it can be understood as the core component of the loading strategy, which is used to clarify the number of coal loading and allocation between each first site and the second site in the strategy, and guide the actual scheduling operation of coal loading.

[0064] Specifically, in order to clarify the coal loading and dispatching plan between stations, it is necessary to match the stations on the basis of fully considering the parameters of each station. This step will systematically consider the three key parameters of the number of coal loading cars to be transferred from each first station, the number of coal loading cars to be allocated at each second station, and the relative distance between any two stations. Then, this step will match and combine the first station and the second station so that the coal loading and dispatching needs of each second station can be met. Here, the above three parameters will be comprehensively considered to optimize the matching plan between stations, and finally a loading and dispatching plan matching multiple stations can be obtained. Each plan determines multiple matching station pairs and the specific number of coal loading and dispatching between each pair.

[0065] Based on the above embodiment, as an optional embodiment, in step 402: combining the number of coal loading cars to be transferred, the number of coal loading cars to be allocated, and the relative distances, matching the first sites with the second sites to obtain multiple loading matching results, this step may also include the following steps: Step 412: For each first site, select multiple target second sites among the second sites where the number of coal loading cars to be allocated is greater than the number of coal loading cars to be transferred, and the difference between the number of coal loading cars to be allocated and the number of coal loading cars to be transferred is less than a threshold.

[0066] Specifically, a suitable second site is matched for each first site. For each determined first site, this step will select a site that meets two conditions from all second sites as the target second site of the first site. The two conditions include: the number of coal loading cars to be allocated at the target second site needs to be greater than the number of coal loading cars to be transferred from the first site. This can ensure that the loading needs of the target second site can be met. The difference in the number of coal loading cars at the two sites needs to be less than a preset threshold. This can balance the loading processing capabilities of the two sites and avoid a lot of waste. By selecting a suitable target second site for each first site, the matching can be made more accurate and effective. Considering the difference threshold can avoid waste of resources and over-allocation.

[0067] Step 422: The target second site with the smallest relative distance to the first site among the target second sites is used as a matching object of the first site, and the first site and the matching object of the first site are used as a loading matching result.

[0068] Specifically, the purpose of this step is to determine the best matching object among the selected target second sites to form a loading matching result. For each first site, this step will select the target second site with the smallest relative distance to the first site from its multiple related target second sites as the final matching object. Selecting the target second site with the closest distance as the matching object can minimize the coal loading and transportation distance between the two sites and save transportation time and cost. Then, this step will take the first site and the corresponding matching object target site as a set of matching results to form a loading matching result. By optimizing the distance to select the matching object, the loading matching result can be made more economical and reasonable, providing a scientific basis for the subsequent formulation of loading strategies. The implementation of this step is conducive to the generation of efficient coal loading scheduling solutions.

[0069] Step 403: Generate a loading strategy based on each loading matching result.

[0070] Specifically, a loading strategy is generated based on the coal loading distribution situation of each first site and the corresponding second site, that is, a strategy for transferring a corresponding amount of coal from the first site to load it to the matching second site. Through this loading strategy, coal loading is allocated to each first site and the second site, which balances the loading load of each site and improves loading efficiency.

[0075] On the basis of the above embodiment, the site division module is also used to obtain the average loading saturation, benchmark loading saturation and average loading time of each loading site within a preset sampling period; calculate the standard deviation of the average loading saturation; determine whether the average loading time is greater than or equal to the loading time threshold; if the average loading time is greater than or equal to the loading time threshold, subtract the preset multiple of the standard deviation from the average loading saturation to obtain the corrected loading saturation threshold; if the average loading time is less than the loading time threshold, increase the average loading saturation by the preset multiple of the standard deviation to obtain the corrected loading saturation threshold.

[0076] Based on the above embodiments, the loading control module is also used to obtain the number of coal loading cars to be transferred away corresponding to each first station, the number of coal loading cars to be allocated corresponding to each second station, and the relative distance between each first station and each second station; combined with the number of coal loading cars to be transferred away, the number of coal loading cars to be allocated and the relative distances, each first station and each second station are matched to obtain multiple loading matching results; based on each loading matching result, a loading strategy is generated.

[0077] On the basis of the above embodiment, the loading control module is also used to select, for each first site, multiple target second sites in each second site where the number of coal loadings to be allocated is greater than the number of coal loadings to be transferred, and the difference between the number of coal loadings to be allocated and the number of coal loadings to be transferred is less than a threshold; the target second site with the smallest relative distance to the first site among each target second site is used as a matching object of the first site, and the first site and the matching object of the first site are used as a loading matching result.
