Although this method improves the sampling efficiency and ensures that the amount of collected coal samples meets the minimum detection standard requirement, when the amount of raw coal is large, the amount of coal samples collected according to the fixed division parameter is also large, and the amount of division retained samples obtained is also large, which increases the quality inspection work intensity of subsequent quality inspectors on the division retained samples, and the fairness of sampling is affected when the amounts of division retained samples of different vehicles are different.

[0034] In order to make the personnel in the technical field better understand the present application, the technical solutions in the present application will be described clearly and completely in combination with the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0035] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0036] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0037] Figure 1A flowchart of a sampling control method for incoming coal provided by the embodiment of the present application, the embodiment can be applicable to the case of randomly sampling the incoming coal, and the method can be executed by a sampling control device for the incoming coal, which can be realized in the form of hardware and / or software and integrated in an electronic device for executing the method. Preferably, the electronic device in the embodiment of the present application can be a server, and can also be a computer device or the like.

[0038] Reference Figure 1 The sampling control method for incoming coal provided by the embodiment includes but is not limited to the following steps:

[0039] S110, determining the sampling parameters of the sampling machine according to the vehicle information of the incoming vehicle.

[0040] Since the coal capacity of different specifications of transport vehicles has a large gap, in order to ensure the fairness of collecting sample coal in different specifications of transport vehicles, the sampling control scheme provided by the embodiment is related to the vehicle information of the incoming vehicle.

[0041] The vehicle information at least includes the vehicle model and the carriage parameter. The vehicle model is used to indicate the vehicle size of the current transport vehicle. Generally, according to the specifications of conventional transport vehicles, the vehicle model can be divided into small vehicles, medium vehicles and large vehicles, etc., and the vehicle model can affect the number of sampling points. For example, the number of sampling points is 3, 5 or 8, etc., and the number of sampling points corresponding to different vehicle models is not limited here; the carriage parameter can be used to describe the physical parameters of the carriage of each vehicle, such as the length, width, height and bottom of the carriage, etc., and the carriage parameter can affect the sampling depth of the sampling points, such as 20 cm, 50 cm or 1 m, etc., and the sampling depth corresponding to different carriage parameters is not limited here. It should be noted that, in order to reflect the randomness and fairness of the sample coal sampling, the number of sampling points corresponding to different vehicle models and the sampling depth corresponding to different carriage parameters can be set as a numerical interval, so as to randomly determine the target sampling number and the target sampling depth when the sampling machine subsequently samples according to the sampling parameters.

[0042] Optionally, in order to facilitate uniform sampling of different vehicles, the vehicle information can also include the position of the reinforcing rib of the vehicle. The reinforcing rib of the vehicle is a necessary device for maintaining the structural strength of the vehicle itself. When sampling and detecting coal, the coal is usually transported to the sampling and detecting position by a vehicle or a train, and then the coal in a number of sampling points in the carriage (i.e. the carriage for transporting coal) is extracted for sampling analysis. In order to ensure the stability of the structure of the carriage, a reinforcing rib is usually arranged between the two side plates of the carriage. Therefore, when sampling the coal in the carriage, the reinforcing rib in the carriage needs to be avoided to prevent damage to the sampling mechanism.

[0043] The scheme provided by the embodiment can pre-adopt a multi-source data fusion technology to construct a basic database about the coal sampling of the coal into the plant. The current basic database can at least include the purchasing data of the coal into the plant (such as the purchased coal quantity, the purchased batch, the coal source supplier, and the planned transportation vehicle and the like), the coal quality data (such as the coal source, the coal quality requirement, and the historical coal quality data of the coal source and the like), and the transportation data of the coal into the plant (such as the vehicle scheduling data, the vehicle structure data, and the vehicle monitoring data and the like). Thus, when the transportation vehicle enters the plant, the vehicle entering the plant can be scanned by the laser radar arranged at the entering position. For example, whether the vehicle is the vehicle in the purchasing plan is determined according to the license plate number obtained by the pre-scanning. If the vehicle is not the vehicle in the purchasing plan, the current vehicle is rejected to enter the plant. Further, if the vehicle is the vehicle in the purchasing plan, the vehicle information related to the current vehicle can be called out in the basic database. Thus, the vehicle information called out and the actually scanned vehicle information are compared. If the comparison is inconsistent, the alarm information can be prompted to verify the compliance of the current vehicle by the manual. If the comparison is consistent, the vehicle model, the carriage parameter, and the position of the tie rod of the current vehicle entering the plant can be at least obtained. Further, the sampling parameters of the sampling machine can be determined according to the current vehicle information.

[0044] In the embodiment, the sampling parameters can at least include the number of sampling points, the sampling position in the carriage, and the sampling depth and the like. Thus, the controller can control the sampling machine to preliminarily collect the sample coal from the carriage of the vehicle entering the plant according to the sampling parameters. The purpose of determining the sampling parameters of the sampling machine according to the vehicle information of the vehicle entering the plant is to automatically customize the sampling parameters of the sampling machine according to the structure size of different vehicles to ensure the fairness and justice of the sampling process.

[0045] S120, acquiring the sampling current when the sampling machine collects the sample coal according to the sampling parameters.

[0046] In the process that the sampling machine collects the sample coal according to the sampling parameters, the controller can monitor the running parameters of the sampling machine in real time. The running parameters of the sampling machine can at least include the running state of the sampling machine and the sampling current and the like. In the embodiment, the purpose of acquiring the sampling current is to determine the moisture and the viscosity of the coal according to the size of the sampling current. For the coal with high moisture and high viscosity, if the conventional sampling scheme is used, the sampling head may be blocked, the crusher may be blocked, and the like, which can damage the sampling equipment and affect the normal operation of the sampling work. Therefore, the embodiment can determine whether the moisture and the viscosity of the coal are too large according to the size of the sampling current. For example, a preset current threshold can be set. When the current sampling current exceeds the preset current threshold, it is determined that the moisture of the coal or the viscosity of the coal is high. The manual sampling process can be triggered to avoid the failure of the sampling equipment.

[0047] Optionally, in the manner of determining whether to trigger the manual sampling process according to the sampling current, the scheme provided by the embodiment can further be combined with historical coal quality information for comprehensive judgment. The specific manner is as follows: the coal source supplier is obtained from the purchase data of the current incoming vehicle, and it is determined whether the current coal source supplier is in the supplier whitelist. If the current coal source supplier is a whitelist supplier, or the sampling current is not greater than the preset current threshold, the subsequent automatic sampling process steps provided by the embodiment are performed; if the current coal source supplier is not a whitelist supplier, and the sampling current is greater than the preset current threshold, the manual sampling process is triggered.

[0048] The whitelist supplier indicates a list of sample coals with good coal quality in the historical sampling process. In the historical coal quality inspection, the list of suppliers whose coal quality score exceeds the preset score, etc.

[0049] S130, determining the crushing parameter of the crusher according to the sampling current, and determining the crushing parameter of the crusher according to the running parameter of the crusher and the coal sample quantity of the sample coal.

[0050] The crusher is a device for further crushing the obtained sample coal. The sample coal after crushing is helpful for accurately analyzing the quality of the current sample coal in the subsequent quality inspection operation.

[0051] In the embodiment, the crushing parameter at least includes the running speed of the crusher and the crushing granularity. The running speed of the crusher is used to indicate the running speed of the crusher, and the crushing granularity is used to indicate the coarse and fine granularity of the sample coal after crushing.

[0052] In the embodiment, the manner of determining the crushing parameter of the crusher according to the sampling current can be that a sampling current and crushing parameter mapping table is set, one sampling current interval corresponds to one corresponding crushing parameter value, so that when the current sampling current is obtained, the target sampling current interval is determined from the crushing parameter mapping table according to the current sampling current, and the crushing parameter value corresponding to the target sampling current interval is determined as the crushing parameter required for the current crusher to run.

[0053] The crusher is a device for further crushing the obtained sample coal. The sample coal after crushing is helpful for accurately analyzing the quality of the current sample coal in the subsequent quality inspection operation.

[0054] In the prior scheme, since the sample quantity is usually divided according to a fixed division parameter, when the raw coal quantity is large, the coal sample quantity collected according to the fixed division parameter is also large. For example, for a raw coal quantity of 30 tons, 3 sampling points are taken, if it is a flat car with a small car depth, generally 3 kg of sample coal is collected; if it is a freight car with a medium car depth, generally 6 kg of raw coal quantity is collected; if it is a container with a large car depth, generally 9 kg of raw coal quantity is collected, but no matter how large the car depth is, only 3 kg of sample coal can meet the quality inspection requirements after sampling, therefore, in order to reduce the quality inspection pressure, the scheme provided in the embodiment is further based on the determination of the sampling parameter of the sampling machine according to the vehicle information of the incoming vehicle based on the scheme provided in the above step S110, and further determines the crushing parameter of the crusher according to the sampling current.

[0055] In the embodiment, the way of determining the division parameter of the divider according to the operation parameter of the crusher and the coal sample quantity of the sample coal can be that the division belt speed is determined according to the operation parameter of the crusher; the division frequency is determined according to the division belt speed and the coal sample quantity; and the division sample quantity is determined according to the division frequency. That is, in order to make the coal sample quantity of the coal from different specifications of vehicles smaller, in the embodiment, the final division sample quantity is related to the division frequency, that is, for the case of a large coal sample quantity, the sample coal can be collected once at a long interval; for the case of a small coal sample quantity, the sample coal can be collected once at a short interval, so that the sum of the division sample quantities corresponding to a plurality of packing bags / packing barrels obtained finally is kept in a small range, so as to obtain a division sample quantity corresponding to a packing bag / packing barrel, and the purpose of reducing the quality inspection work intensity of the quality inspection personnel on the division sample quantity of the coal from the same vehicle is achieved.

[0056] S140, packing and batching the sample coal according to the division parameter, and completing the sampling operation of the incoming coal.

[0057] In the process of packing and batching the sample coal according to the division parameter, the divided coal samples can be collected and packaged by the ore divider.

[0058] In the process of packing and batching the sample coal in the present embodiment, the sampling result data of the sample coal (such as the coal sample particle size, the coal sample barrel weight / packed coal sample weight, etc.) can also be recorded in the technical database. The historical coal quality data includes the calorific value, moisture, etc., the sampling set data includes the sampling head structure, size, motor current, etc., the crusher data includes the crusher rotating speed, crushing current, etc., the classifier data includes the classification ratio adjustment range, classification ratio, motor current, etc., the sample divider data includes the barrel number, sample quantity, coal sample weight, etc., and the packing data includes the packing size, packing bag number, sampling card, coal sample weight, etc. The sampling frequency or calculation frequency of these data, the data structure, the storage database and the read-write mode are different, and a corresponding collection, analysis, calculation and storage strategy is formulated by using the multi-source data fusion technology, and all the data are fused to form the sampling data structure of the incoming truck coal. According to the sampling frequency and data characteristics of the data, the data are stored in the time sequence, structured and unstructured heterogeneous databases. Through the scheme provided by the present embodiment, the intelligent degree of the sampling process of the incoming truck coal is improved, and then the working efficiency and sampling quality of the sampling process are improved, and the interference of human factors in the sampling process is reduced.

[0059] The sampling control method of the incoming coal provided by the present embodiment first determines the sampling parameters of the sampling machine according to the vehicle information of the incoming vehicle; then acquires the sampling current of the sampling machine when collecting the sample coal according to the sampling parameters; then determines the crushing parameters of the crusher according to the sampling current, and determines the classification parameters of the classifier according to the operating parameters of the crusher and the coal sample quantity of the sample coal; and finally packs and batches the sample coal according to the classification parameters, and completes the sampling operation of the incoming coal. The scheme provided by the present embodiment can determine the sampling parameters through the vehicle information of the incoming coal, and can also determine the corresponding crushing parameters in the subsequent crushing link and the corresponding classification parameters in the classification link through the sampling current, so as to dynamically determine the corresponding sampling parameters, crushing parameters and classification parameters for the incoming coal transported by different vehicles, and the classification sample quantity obtained by the above-mentioned method can reduce the fluctuation range of the classification sample quantity determined from different vehicles, and improve the beneficial effect of the fairness of coal sample collection.

[0060] Figure 2 is another flowchart of the sampling control method of the incoming coal provided by the present embodiment, and the present embodiment is optimized on the basis of the above-mentioned embodiments, and the specific optimization is that the present embodiment explains and describes the related processes of "determining the sampling parameters of the sampling machine according to the vehicle information of the incoming vehicle" and "determining the classification parameters of the classifier according to the sampling current and the coal sample quantity of the sample coal" in the above-mentioned embodiments in detail.

[0061] Referring to Figure 2 The method provided by the present embodiment includes but is not limited to the following steps:

[0062] S210, determine a preset number of sampling points according to the vehicle model and determine the sampling depth corresponding to each sampling point.

[0063] Before determining the preset number of sampling points according to the vehicle model, first determine the positioning data of the vehicle compartment in the sampling area based on the laser radar. Wherein, the sampling area can be understood as the area that the vehicle can be opened to the sampling machine can sample. Since the area that the sampling machine can sample is a larger area range, which at least contains the whole vehicle (the position range from the front to the rear of the vehicle), but the sampling machine needs to sample the coal in the vehicle compartment, therefore, in order to ensure the accuracy of the sampling machine, the positioning data of the vehicle compartment in the sampling area needs to be determined in advance. The current positioning data can be the coordinates of the four corners of the vehicle compartment obtained by the laser radar, so as to determine the positioning data according to the coordinates of the four corners.

[0064] Further, the embodiment can determine different sampling points corresponding to different vehicle models. The vehicle model is divided into small vehicle, medium vehicle and large vehicle according to the volume of the vehicle compartment, and the preset number of sampling points corresponding to each vehicle model includes 3, 5 and 8 as an example. Each sampling point can correspond to different sampling depth. For example, the determined number of sampling points includes a, b and c, and the sampling depth corresponding to each sampling point can be h1, h2 and h3. Wherein, the sampling depth can have the following relationship: h1>h2>h3, and the relationship between the sampling depth corresponding to each sampling point is not limited herein. The purpose of this is to ensure the randomness and uniformity of the subsequent sample coal collection, and to improve the fairness of the coal sample collection.

[0065] S211, determine the sampling coordinates corresponding to each sampling point from the sampling coordinate library corresponding to the vehicle model based on the preset rule.

[0066] In the embodiment, one vehicle model can correspond to one sampling coordinate library, and the sampling coordinate library includes N sampling coordinates, each of which is obtained by calculating the vehicle compartment parameters and the position of the reinforcing rib corresponding to the vehicle model. The purpose of this is to ensure the randomness and effectiveness of the sampling coordinates when automatically determining the sampling coordinates according to the vehicle model, and to prevent the sampling machine from touching the reinforcing rib position of the vehicle and causing damage to the sampling machine or the vehicle.

[0067] Specifically, the embodiment of the present application provides a preferred implementation, in which, in the embodiment, the manner of determining the sampling coordinates corresponding to each sampling point from the sampling coordinate library corresponding to the vehicle model based on the preset rule can be: determining whether the vehicle identifier of the incoming vehicle is a preset identifier; if the vehicle identifier of the incoming vehicle is the preset identifier, determining a preset number of coordinates from the sampling coordinate library as the sampling coordinates corresponding to each sampling point, and marking the preset number of coordinates with a first identifier; if the vehicle identifier of the incoming vehicle is not the preset identifier, determining a preset number of coordinates not containing the first identifier from the sampling coordinate library as the sampling coordinates corresponding to each sampling point. In this way, the purpose is to select the preset number of coordinates not marked with the first identifier from the sampling coordinate library as the current sampling coordinates, which can ensure the randomness of sampling.

[0068] The vehicle identifier can be used to indicate the vehicle serial number of the current sampled vehicle, and the preset identifier can indicate the identifier with the first serial number. Therefore, when the vehicle identifier of the current vehicle is the identifier corresponding to the first vehicle corresponding to the current vehicle model, a corresponding number of coordinates can be randomly selected from the sampling coordinate library as the coordinates corresponding to each sampling point; and after the current coordinates are selected, the current coordinates are marked with the first identifier to indicate that the current coordinates have been selected; therefore, when the vehicle identifier of the incoming vehicle is not the first one, a corresponding number of coordinates are randomly selected from the remaining coordinates in the sampling coordinate library (i.e., the coordinates not marked with the first identifier) as the sampling coordinates this time, and the first identifier is marked after the current coordinates are selected, and the same is repeated until all the sampling coordinates in the sampling coordinate library are marked with the first identifier, and the first identifier corresponding to each sampling coordinate is emptied, and the random selection is performed again from all the sampling coordinates, so as to ensure that all the sampling coordinates can be randomly and uniformly sampled, and the aggregation of the sampling point coordinates can be avoided.

[0069] S212, obtaining the sampling parameters of the sampling machine according to the sampling coordinates and the sampling depths.

[0070] The controller can control the sampling machine to obtain the sample coal from the vehicle compartment according to each sampling coordinate and the sampling depth corresponding to each sampling coordinate, and then perform a subsequent processing procedure on the currently collected sample coal, so that the processed sample coal meets the quality inspection requirements and can be used for quality inspection evaluation.

[0071] S220, obtaining the sampling current when the sampling machine collects the sample coal according to the sampling parameters.

[0072] S230, obtaining the coal source information of the sample coal.

[0073] The coal source information of the sample coal can be used to indicate the supplier of the current batch of coal and the historical coal quality data provided by the current supplier, and the current coal source information can be directly called from the database for reference to evaluate the quality of the current coal.

[0074] S231, determine whether the coal source identifier corresponding to the coal source information is a white list identifier or whether the sampling current is not greater than a preset current threshold.

[0075] If the coal source identifier is a white list identifier or the sampling current is not greater than the preset current threshold, that is, yes, step S240 is executed; in this embodiment, if either the coal source identifier or the sampling current meets the condition, the sample coal can be controlled to be transmitted into the crusher through the coal conveying belt to execute the crushing scheme.

[0076] If the coal source identifier is not a white list identifier and the sampling current is greater than the preset current threshold, that is, no, step S250 is executed.

[0077] The coal source identifier is an identifier corresponding to each supplier. The white list is used to indicate a list in which the identifiers of the suppliers whose historical coal is evaluated to have good coal quality are located. The preset current threshold is used to indicate the coal quality information of the sample coal. If the sampling current is not greater than the preset current threshold, it indicates that the moisture content in the coal quality information of the coal this time is low, or the viscosity is low.

[0078] S240, determine the coal quality information of the sample coal according to the sampling current.

[0079] In this embodiment, the coal quality information includes coal quality moisture and / or coal quality viscosity. The greater the moisture or the higher the viscosity, the greater the corresponding sampling current.

[0080] The way of determining the coal quality information of the sample coal according to the sampling current can be that a sampling current and coal quality information mapping table is provided, so that the corresponding coal quality moisture content and / or coal quality viscosity condition can be determined according to the current sampling current value.

[0081] S241, determine the crushing rotational speed and the crushing particle size of the crusher according to the coal quality moisture and / or the coal quality viscosity and the historical crushing record corresponding to the coal source information.

[0082] In this embodiment, the crushing parameters of the crusher include the crushing rotational speed and the crushing particle size. When determining the crushing rotational speed and the crushing particle size of the crusher running, in addition to being related to the coal quality moisture and / or the coal quality viscosity, the historical crushing record corresponding to the current coal source information is further referred to, so as to determine the theoretical crushing parameters according to the coal quality moisture and / or the coal quality viscosity, and then the historical crushing parameters contained in the historical crushing record are comprehensively considered, so as to determine the current crushing parameters, to generate the crushing scheme according to the crushing parameters, and automatically download the crushing scheme to the crushing controller, so as to automatically control the crusher to crush the sample coal to the set coal sample particle size according to the crushing parameters, and monitor the state of the crusher in real time.

[0083] S250, control the crushing parameters of the crusher to be preset values.

[0084] The current step indicates that when it is determined that the coal source identifier is not the white list identifier and the sampling current is greater than the preset current threshold, it indicates that the coal quality of the current incoming coal is poor, and if the sample coal is controlled to enter the crusher, it is easy to cause the crusher to be blocked and other faults. Therefore, at this time, the scheme of not crushing the sample coal can be adopted, that is, the crushing parameter of the crusher is controlled to be a preset value, and the current preset value can be that the crushing speed of the crusher is 0, that is, the crusher is controlled not to operate, and the sample coal is automatically controlled to enter the next step of the splitting link through the bypass.

[0085] S260, determining the splitting belt speed according to the crushing current.

[0086] The operation parameters of the crushing machine include the crushing current; and the splitting parameters of the splitter include the splitting sample quantity.

[0087] The splitting parameters of the splitter provided in the embodiment at least include the splitting sample quantity. The splitting sample quantity is used to indicate the weight of the sample coal corresponding to each packed coal sample. In the embodiment, when the splitting belt speed is determined according to the crushing current, the splitting belt speed corresponding to a small sampling current can be large, and correspondingly, one sampling current interval can be set to correspond to one splitting belt speed, so that after the sampling current is obtained, the corresponding splitting belt speed is automatically matched according to the current sampling current to control the splitting belt to operate according to the current speed.

[0088] Correspondingly, when the coal source identifier of the sample coal is not the white list identifier and the sampling current is greater than the preset current threshold, the scheme provided in the embodiment will not perform the crushing operation on the sample coal, and when the splitting parameters of the splitter are determined, the splitting belt speed can be determined according to the sampling current of the sampling machine.

[0089] S261, determining the splitting frequency according to the splitting belt speed and the coal sample quantity.

[0090] The way of determining the splitting frequency according to the splitting belt speed and the coal sample quantity can be that for the case that the coal sample quantity is large, the sample coal can be collected once every long splitting frequency interval; and for the case that the coal sample quantity is small, the sample coal can be collected once every short splitting frequency interval, so that the sum of the splitting sample quantities corresponding to the plurality of packing bags / packing barrels obtained finally is kept in a small range, so as to obtain the splitting sample quantity corresponding to one packing bag / packing barrel, and the purpose of reducing the quality inspection work intensity of the quality inspection personnel on the splitting sample quantity of the coal from the same vehicle is achieved.

[0091] S262, determining the splitting sample quantity according to the splitting frequency.

[0092] The splitter can collect the splitting sample quantity once every splitting frequency interval.

[0093] In another preferred implementation, determining the split sample quantity according to the splitting frequency is also related to the packing and batching mode, and the specific mode can be: obtaining the packing and batching mode; determining the split sample quantity corresponding to each packed coal sample according to the packing and batching mode and the splitting frequency.

The packing and batching mode of the packer includes a plurality of types, such as 1 car 2 bags (one truck collects 2 bags of split samples), 1 car 1 bag (one truck collects 1 bag of split samples), but no matter how many bags are divided, the total split sample quantity on each truck remains unchanged, so that the weight of each bag can be evenly divided according to the packing type to obtain the split sample quantity corresponding to each packed coal sample, etc.

[0095] S270, packing and batching the sample coal according to the splitting parameters to complete the sampling operation of the incoming coal.

[0096] For the sampling system using a mineral separator, a sample coal mixing and batching scheme of the incoming coal mineral separator is automatically generated according to the sampling quantity of the coal sample and vehicle information, in combination with the number of barrels of the mineral separator and its weight setting, etc. The sample coal mixing and batching scheme is automatically downloaded to a batching controller to automatically control the mineral separator to perform coal sample mixing, and the state of the mineral separator and the weight of the coal sample barrel are monitored in real time. When the weight of the coal sample barrel meets the standard, the sealed coal sample barrel is delivered to the pre-preparation link.

[0097] For the sampling system using a packer, a packing scheme of the incoming coal packer is automatically generated according to the sampling quantity of the coal sample and vehicle information, in combination with the structural characteristics of the packer and the packing and batching mode (1 car 2 bags, 1 car 1 bag). The packing scheme is automatically downloaded to a packer controller to automatically control the packing of the packer, and the state of the packer and the weight of the coal sample bag are monitored in real time. A sample coal mixing and batching scheme is generated, which is automatically downloaded to a batching controller to automatically control the mixing of the coal sample, and the batching state of the coal sample cabinet and the total weight of the coal sample are monitored in real time. When the total weight of the coal sample meets the standard, the coal sample bag is no longer delivered to the coal sample cabinet, and the operator is prompted that the coal sample in the coal sample cabinet can be delivered to the pre-preparation link.

[0098] In another optional embodiment, the sampling control method for incoming coal provided in the embodiment can be integrated in a sampling control system for incoming coal.
