[0035] Figure 1It is a flow chart of the method for determining the coal shifting effect of a coal feeder provided in an embodiment of the present application. This embodiment can be applied to scenarios where the coal shifting effect of a coal feeder needs to be determined. The method for determining the coal shifting effect of a coal feeder provided in this embodiment can be executed by a device for determining the coal shifting effect of a coal feeder provided in an embodiment of the present application, and the device can be implemented in software and / or hardware. In a specific embodiment, the device for determining the coal shifting effect of a coal feeder can be integrated in an electronic device of a coal conveying system, and the electronic device is a controller of the entire coal conveying system. For example, the electronic device can be a computer or a server. The execution subject of this method can be an electronic device.

[0036] In a specific embodiment, the coal transportation system may include electronic equipment, a coal feeder, a belt, a metering device and multiple coal bins; and the coal feeder moves along a track above the belt, multiple coal bins are arranged above the belt in a preset order, and a metering device is installed below the belt.

[0037] Among them, the coal bunker is used to receive coal transported by external transportation equipment (such as trains or coal trucks, etc.) and store the coal, and each of the multiple coal bunkers is a separate independent coal bunker, which is arranged above the belt in a preset arrangement order, generally obliquely above, and the arrangement height of the multiple coal bunkers can ensure that the coal feeder can perform coal shifting operations on it; the coal feeder is used to transport the coal in the coal bunker to the belt, such as the impeller coal feeder uses the rotation of the impeller to shift the coal in the coal bunker onto the belt; the rotating motor at the bottom of the belt can drive the belt to move, and is used to transport the coal taken out of the coal bunker by the coal feeder to a designated location, such as the raw coal hopper of a boiler or other coal processing equipment; the metering equipment is used to measure various parameters of the coal transported on the belt, such as weight or pressure, and the metering equipment can be equipment such as a belt scale or a pressure sensor.

[0038] See also Figure 1 The method for determining the coal shifting effect of the coal feeder of this embodiment includes but is not limited to the following steps:

[0039] S110, obtaining a target time interval for the coal feeder to pass through each coal bin, and coal quantity data detected by the metering equipment within the target time interval.

[0040] Among them, the target time interval is the time range for the coal feeder to pass through a specific coal bin, that is, the time period from the starting moment when the coal feeder starts to pass through a coal bin to the ending moment when it completely passes through the coal bin; within the target time interval, the coal feeder can take coal from the corresponding coal bin.

[0041] The coal quantity data is the coal quantity information of the coal transported on the belt by the metering device within the target time interval. For example, the metering device may be a pressure sensor, and the coal quantity data at this time is the pressure of the coal transported on the belt.

[0042] Specifically, when the coal feeder does not fully move the coal, different weights of coal will be left in multiple coal bins. Therefore, it is necessary to determine the coal moving effect of the coal feeder on multiple coal bins, so as to improve the coal moving effect of the coal feeder in a targeted manner. At this time, the target time interval for the coal feeder to pass through each coal bin can be obtained. For example, in one implementation method, before the coal feeder officially carries out the coal moving operation, the coal feeder and the belt can be controlled to operate according to the actual working state, and the time range for the coal feeder to pass through each coal bin can be recorded during the operation, so as to obtain the target time interval corresponding to each coal bin.

[0043] In another implementation method, a position sensor, such as an infrared sensor, can be installed on one or both sides of the track (i.e., the track along which the coal feeder moves), and the corresponding starting position and ending position of each coal bin on the track can be marked. Then, while the coal feeder is moving coal along the track, the target time interval for the coal feeder to pass through each coal bin is determined based on the detection data of the position sensor. That is, for the current coal bin in each coal bin, when the position sensor detects the starting position mark of the coal feeder entering the current coal bin, the moment is recorded to obtain the starting time. Then, when the position sensor detects the ending position mark of the coal feeder leaving the current coal bin, the moment is recorded to obtain the ending time, thereby obtaining the target time interval corresponding to the current coal bin.

[0044] Afterwards, the coal quantity data detected by the metering equipment at each moment in the target time interval can be obtained, such as the pressure data of the coal transported by the belt at each moment, so as to obtain multiple coal quantity data included in each target time interval.

[0045] S120. Determine the coal quantity change trend within the corresponding target time interval according to the coal quantity data, and determine the coal quantity remaining state of the corresponding coal bunker according to the coal quantity change trend.

[0046] The coal quantity change trend refers to the trend of coal quantity increase, decrease or stability presented by the coal quantity data within the target time interval, that is, the trend of coal quantity data of the coal transported on the belt changing over time.

[0047] The coal quantity remaining state refers to the amount of coal remaining in the coal bunker after the coal feeder passes through the coal bunker. Exemplarily, the coal quantity remaining state may include an empty state, a non-empty bunker state, and an un-dug bunker state; the empty state is used to indicate that the amount of coal in the coal bunker has been basically emptied after the coal feeder passes through the coal bunker; the non-empty bunker state is used to indicate that after the coal feeder passes through the coal bunker, there is still a certain weight of coal in the coal bunker that has not been removed, that is, the coal bunker has not been emptied; the un-dug bunker state is used to indicate that after the coal feeder passes through the coal bunker, the amount of coal in the coal bunker has hardly changed, that is, the coal feeder has not performed effective coal removal operations on the coal bunker.

[0048] Specifically, after obtaining the coal quantity data, the coal quantity change trend in the corresponding target time interval can be determined according to the coal quantity data, that is, any target time interval can be selected as the current target time interval, and a line graph can be drawn based on the coal quantity data at each moment in the current target time interval, wherein the horizontal axis of the line graph is time, and the vertical axis is the coal quantity data measured by the metering equipment, which is used to characterize the coal quantity change trend of the coal transported on the belt in the current target time interval. Then, the coal quantity change trend in the current target time interval is determined according to the line graph, such as an upward trend, a horizontal trend or a downward trend, etc., and then other target time intervals can be selected as the current target time interval, and the above process can be repeated to obtain the coal quantity change trend in each target time interval.

[0049] Afterwards, the coal quantity legacy state of the corresponding coal bunker can be determined according to the coal quantity change trend. For example, any coal bunker is selected as the current coal bunker, and the coal quantity change trend of the coal feeder passing through the current coal bunker within the target time interval is obtained. Then, the coal quantity change trend and the preset standard curve are compared to determine the coal quantity legacy state of the current coal bunker. Then, other coal bunkers are selected as the current coal bunker, and the above process is repeated to obtain the coal quantity legacy state of each coal bunker. Among them, the preset standard curve is the standard pressure change trend of the coal transported on the belt during the process of the coal feeder dropping all the coal in the coal bunker onto the belt within the target time interval. It is used to determine whether the coal quantity change trend is the standard pressure change trend, so as to determine the coal quantity legacy state of the coal bunker.

[0050] Specifically, if the changing trend and the degree of change of the coal quantity changing trend are the same as the changing trend and the degree of change of the preset standard curve, then the coal quantity remaining state of the corresponding coal bin is determined to be an empty state; if the changing trend of the coal quantity changing trend is the same as the changing trend of the preset standard curve, but the degree of change of the coal quantity changing trend is less than the degree of change of the preset standard curve, then the coal quantity remaining state of the corresponding coal bin is determined to be a not empty bin state; if the coal quantity changing trend is a horizontal trend, then the coal quantity remaining state of the corresponding coal bin is determined to be an un-dug bin state.

[0051] S130. Determine the coal feeding effect of the coal feeder according to the remaining coal quantity corresponding to each coal bunker.

[0052] Among them, the coal shifting effect refers to the working effect of the coal feeder in shifting the coal in the coal bin onto the belt; the coal shifting effect can include high, medium and low.

[0053] Specifically, after obtaining the coal quantity legacy status corresponding to each coal bin, the coal shifting effect of the coal feeder can be determined according to the coal quantity legacy status corresponding to each coal bin, that is, the number of coal bins whose coal quantity legacy status is an empty state can be determined, recorded as the emptying number, and the number of coal bins whose coal quantity legacy status is an un-dug bin state can be determined, recorded as the un-dug bin number. When the emptying number exceeds the first preset number threshold, the coal shifting effect of the coal feeder can be determined to be high; when the emptying number does not exceed the first preset number threshold, and the un-dug bin number exceeds the second preset number threshold, the coal shifting effect of the coal feeder can be determined to be low; when the emptying number does not exceed the first preset number threshold, and the un-dug bin number does not exceed the second preset number threshold, the coal shifting effect of the coal feeder can be determined to be medium. Among them, the first preset number threshold and the second preset number threshold are numerical values ​​pre-set according to the total number of coal bins in the coal transportation system, which are used to determine the coal shifting effect of the coal feeder, and the first preset number threshold is greater than the second preset number threshold. The user can adjust and set the first preset number threshold and the second preset number threshold according to actual usage needs.

[0054] The technical solution of the embodiment of the present application can obtain the target time interval for the coal feeder to pass through each coal bin, and the coal quantity data detected by the metering equipment within the target time interval, and then determine the coal quantity change trend within the corresponding target time interval based on the coal quantity data, and determine the coal quantity legacy status of the corresponding coal bin based on the coal quantity change trend, and then determine the coal shifting effect of the coal feeder according to the coal quantity legacy status corresponding to each coal bin, and the coal shifting effect of the coal feeder can be automatically determined. In the above technical scheme, the coal quantity data detected by the metering equipment within the target time interval can be used to automatically determine the coal quantity change trend of the coal transported on the belt when the coal feeder passes through each coal bin, and then the coal quantity legacy status of each coal bin can be further quickly determined without relying on manual observation of the coal bin, saving manpower and time consumed by manual observation, and improving the working environment of the operators, further improving the efficiency of determining the coal shifting effect, and effectively solving the problem of low efficiency in determining the coal shifting effect in the prior art; at the same time, according to the target time interval of the coal feeder passing through each coal bin and the coal quantity data detected by the metering equipment, the coal quantity change trend of the coal transported on the belt within each target time interval can be accurately determined, thereby improving the accuracy of determining the coal quantity legacy status of each coal bin, and further improving the accuracy of determining the coal shifting effect, which helps to guide the coal shifting operation of the coal feeder, thereby improving the operating efficiency of the coal feeder, reducing the electricity cost of the coal transportation system, and enhancing the competitiveness of thermal power companies, which is of great significance to realizing digitalization and intelligence and promoting high-quality transformation and development of the thermal power sector.

[0055] The following further describes a method for determining the coal shifting effect of a coal feeder provided in an embodiment of the present application. Figure 21 is another flow chart of the method for determining the coal shifting effect of the coal feeder provided in the embodiment of the present application. The embodiment of the present application is optimized on the basis of the above embodiments. Figure 2 The method of this embodiment includes but is not limited to the following steps:

[0056] S210. Acquire first motion state information of the belt and second motion state information of the coal feeder.

[0057] Among them, the first motion state information is the relevant state data when the belt moves; the first motion state information may include a first motion direction and a first speed; the first motion direction is the motion direction when the belt moves, and the first speed is the running speed when the belt moves.

[0058] The second motion state information is the relevant state data when the coal feeder moves along the track above the belt; the second motion state information may include a second motion direction and a second speed; the second motion direction is the motion direction when the coal feeder moves along the track above the belt, and the second speed is the running speed when the coal feeder moves along the track above the belt; and the first speed is greater than the second speed. It should be noted that the belt and the coal feeder are both set to move at a constant speed.

[0059] Specifically, since the belt and coal feeder are pre-set to move at a uniform speed, the movement direction and running speed pre-set by the user for the belt can be obtained to obtain the first movement state information, and the movement direction and running speed pre-set by the user for the coal feeder can be obtained to obtain the second movement state information.

[0060] S220. Determine the relative speed of the coal feeder according to the first motion state information and the second motion state information.

[0061] Among them, the relative speed is the running speed of the coal feeder relative to the coal bunker.

[0062] Specifically, since the first movement direction and the second movement direction may be the same or different, when the first movement direction is the same as the second movement direction, the relative speed can be determined as the sum of the first speed and the second speed; when the first movement direction is opposite to the second movement direction, the relative speed can be determined as the difference between the first speed and the second speed. The calculation strategy of the relative speed is determined by the directional relationship between the first movement direction and the second movement direction, which reduces the implementation complexity, improves the calculation efficiency, and thus improves the determination efficiency and accuracy of the relative speed, so that regardless of whether the movement directions of the coal feeder and the belt are the same, the relative speed can be accurately determined according to the corresponding calculation strategy, which will not affect the accuracy of the subsequent target time interval, thereby providing an accurate data basis for the subsequent determination of the target time interval and improving the applicability, that is, it is suitable for the working scenario where the coal feeder performs coal shifting operations on the coal bunker in two movement directions, wherein the two movement directions include the same as the movement direction of the belt and the opposite to the movement direction of the belt.

[0063] S230. Determine a target time interval for the coal feeder to pass through each coal bin based on the relative speed.

[0064] Specifically, the target time interval for the coal feeder to pass through each coal bin is determined based on the relative speed, including Sa1-Sa3:

[0065] Sa1. Get the belt length and number of coal bins.

[0066] Among them, the belt length is the total length of the belt used to transport coal in the coal transportation system; the number of coal bunkers is the total number of coal bunkers in the coal transportation system.

[0067] Sa2. Determine the unit time based on the belt length, number of coal bins and relative speed.

[0068] The unit duration is used to characterize the time required for the coal feeder to pass through each coal bunker. It can quantify the time it takes for the coal feeder to transfer coal to each coal bunker, making it easier to determine the specific time interval for the coal feeder to pass through each coal bunker.

[0069] Specifically, after obtaining the belt length and the number of coal bins, the ratio of the belt length to the relative speed can be calculated to obtain the total time, and the ratio of the total time to the number of coal bins can be calculated to obtain the average time the coal feeder passes through each coal bin, that is, the unit time.

[0070] Sa3. Based on the unit time length and the preset arrangement order of multiple coal bunkers, determine the target time interval for the coal feeder to pass through each coal bunker.

[0071] For example, it is known that the unit time length is 10 seconds, the number of coal bins is 5, the preset arrangement order of the 5 coal bins is Coal Bin No. 1, Coal Bin No. 2, Coal Bin No. 3, Coal Bin No. 4 and Coal Bin No. 5, and the coal feeder starts the coal transfer operation at 8:00:00, then the target time interval for the coal feeder to pass through Coal Bin No. 1 is [8:00:00, 8:00:10], the target time interval for the coal feeder to pass through Coal Bin No. 2 is [8:00:10, 8:00:20], the target time interval for the coal feeder to pass through Coal Bin No. 3 is [8:00:20, 8:00:30], the target time interval for the coal feeder to pass through Coal Bin No. 4 is [8:00:30, 8:00:40], and the target time interval for the coal feeder to pass through Coal Bin No. 5 is [8:00:40, 8:00:50].

[0072] In the embodiment of the present application, the efficiency and accuracy of determining the unit time can be improved through the belt length, the number of coal bins and the relative speed, and the time for the coal feeder to perform coal shifting operations on each coal bin is quantified, which is convenient for the subsequent determination of the specific time interval for the coal feeder to pass through each coal bin; then, based on the unit time and the preset arrangement order, the target time interval can be determined without the aid of additional position sensors, which reduces the implementation complexity and improves the calculation efficiency, thereby improving the efficiency and accuracy of determining the target time interval, saving the determination cost, and providing an accurate data basis for the subsequent determination of the remaining coal quantity in each coal bin.

[0073] S240. Obtain coal quantity data detected by the metering equipment within the target time interval.

[0074] Optionally, the metering device is a belt scale. In this case, the coal quantity data is the weight of the coal transported on the belt, which can accurately analyze the trend of the weight of the coal transported on the belt over time.

[0075] S250. Determine the coal quantity change trend within the corresponding target time interval according to the coal quantity data, and determine the coal quantity remaining status of the corresponding coal bunker according to the coal quantity change trend.

[0076] Optionally, the coal quantity change trend may include a step trend and a horizontal trend.

[0077] Specifically, after obtaining the coal quantity data, the coal quantity change trend within the corresponding target time interval can be determined according to the coal quantity data, that is, a line graph can be drawn based on the coal quantity data detected by the metering equipment within the target time interval, wherein the horizontal axis of the line graph is time, and the vertical axis is the coal quantity data measured by the belt scale, which is used to characterize the change trend of the coal quantity data of the coal transported on the belt over time when the coal feeder performs coal feeding operations; then the coal quantity change trend within each target time interval is determined according to the line graph. For example, when the change trends of the coal quantity data within the current target time interval are an upward trend, a horizontal trend, a downward trend and a horizontal trend respectively, it can be determined that the coal quantity change trend within the current target time interval is a step trend; when the change trend of the coal quantity data within the current target time interval is always a horizontal trend, it can be determined that the coal quantity change trend within the current target time interval is a horizontal trend.

[0078] Then, the coal quantity remaining status of the corresponding coal bin can be determined according to the coal quantity change trend, that is, in the process of the coal in a coal bin being completely pushed onto the belt by the coal feeder, the weight of the coal transported on the belt will form a step signal (i.e., a mutation signal), that is, the coal quantity data measured by the belt scale will form a step change trend, and the step amplitude of the step signal exceeds the set threshold. Therefore, when the step amplitude exceeds the set threshold, it can be determined that the coal feeder has swept away the coal in the coal bin. Therefore, when the coal quantity change trend is a step trend and the step amplitude exceeds the set threshold, the coal quantity remaining status of the corresponding coal bin can be determined. The state is the empty state; when the step amplitude of the coal quantity change trend does not exceed the set threshold, the coal quantity legacy state of the corresponding coal bin can be determined to be the legacy state; the set threshold is the critical value of the predetermined coal quantity change amplitude, that is, the standard weight change amplitude of the coal transported on the belt during the process of the coal feeder shifting all the coal in the coal bin onto the belt within the target time interval, which is used to determine the coal quantity legacy state of the coal bin. The user can adjust and set the set threshold according to actual use requirements, and the embodiment of the present application does not make specific restrictions on this; the legacy state is the state where there is still coal left in the coal bin after the coal feeder passes through the coal bin. The step trend of the coal quantity data measured by the belt scale over time is used as a direct reference quantity to feedback the coal feeder's coal shifting effect on each coal bin, and combined with the set threshold, the coal quantity legacy state of each coal bin can be accurately determined, which reduces the implementation complexity and improves the calculation efficiency, thereby improving the accuracy and efficiency of determining the coal quantity legacy state, and providing an accurate data basis for the subsequent determination of the coal shifting effect.

[0079] Furthermore, the legacy state may include a non-empty state and an un-dug state, that is, when the coal quantity change trend is a step trend and the step amplitude does not exceed the set threshold, the coal quantity legacy state of the corresponding coal bunker can be determined to be a non-empty state; when the coal quantity change trend is a horizontal trend, the coal quantity legacy state of the corresponding coal bunker can be determined to be an un-dug state. By further refining the legacy state to include a non-empty state and an un-dug state, the coal quantity legacy state of the coal bunker can be determined more accurately; when the coal quantity legacy state is determined to be a non-empty state, the working parameters of the coal feeder can be appropriately optimized according to the step amplitude of the coal quantity change trend, so that the coal feeder can perform coal shifting operations more efficiently, while reducing energy consumption and equipment wear; and when the coal quantity legacy state is determined to be an un-dug state, it may mean that the coal feeder is not working properly or there is a problem with the connection with the coal bunker, which can provide clear clues for fault detection of the coal feeder, thereby ensuring the stable operation of the coal feeder.

[0080] For example, Figure 3a The figure shows an example of the initial state provided by the embodiment of the present application. Figure 3a There are n coal bunkers, and each bunker stores the same weight of coal; Figure 3a The coal feeder in the figure is an impeller coal feeder, and the metering device is a belt scale. At this time, the coal quantity data detected by the belt scale is the weight of the coal transported on the belt; the coal quantity data detected by the belt scale is plotted into a line graph with time as the horizontal axis and the coal quantity data measured by the belt scale as the vertical axis, as shown in Figure 3b As shown, Figure 3b The black straight line in the figure represents the weight change of the coal transported on the belt when the coal bunker is in the initial state. The red dotted line is the set threshold. At this time, the coal feeder has not started the coal feeding operation. Since the belt has a certain weight, in the initial state, although the weight of the coal transported on the belt is zero, the coal quantity data is not zero, but the weight of the belt.

[0081] For example, Figure 4a The figure shows an example of a clearing state provided by an embodiment of the present application. Figure 4a The coal in the n coal bunkers is completely emptied by the impeller coal feeder; during the coal feeding operation of the impeller coal feeder, the belt scale can detect the coal quantity data (i.e. weight) of the coal transported on the belt in real time; the coal quantity data detected by the belt scale is plotted into a line graph with time as the horizontal axis and the coal quantity data measured by the belt scale as the vertical axis, as shown in Figure 4b As shown, Figure 4bThe black curve in the figure represents the coal quantity change trend of the coal transported on the belt during the coal feeding process of the impeller coal feeder. The red dotted line is the set threshold. When the impeller coal feeder passes through each coal bin, the coal quantity change trend in the target time interval is a step trend, and the step amplitude exceeds the set threshold, indicating that the coal quantity remaining state of each of the n coal bins is empty.

[0082] For example, Figure 5a The figure shows an example of a legacy state provided by an embodiment of the present application. Figure 5a There are coals of different weights stored in the n coal bunkers, that is, the impeller coal feeder does not fully move the coal; during the coal moving operation of the impeller coal feeder, the belt scale can detect the coal quantity data (i.e. weight) of the coal transported on the belt in real time; the coal quantity data detected by the belt scale is plotted into a line graph with time as the horizontal axis and the coal quantity data measured by the belt scale as the vertical axis, as shown in Figure 5b As shown, Figure 5b The black curve in the figure represents the coal quantity change trend of the coal transported on the belt during the coal shifting process of the impeller coal feeder. The red dotted line is the set threshold value. When the impeller coal feeder passes through the No. 3 coal bunker, the coal quantity change trend is a horizontal trend, that is, the coal quantity remaining state of the No. 3 coal bunker is an un-dug bunker state; when the impeller coal feeder passes through the No. 4 coal bunker, the coal quantity change trend is a horizontal trend, that is, the coal quantity remaining state of the No. 4 coal bunker is an un-dug bunker state; when the impeller coal feeder passes through the n-1 coal bunker, the coal quantity change trend is a step trend, but the step amplitude does not exceed the set threshold value, that is, the coal quantity remaining state of the n-1 coal bunker is a non-empty bunker state; the coal quantity remaining state of the remaining coal bunkers is an empty state.

[0083] Optionally, after determining the legacy coal status of the corresponding coal bin according to the coal quantity change trend, the legacy coal bin can be determined from multiple coal bins according to the legacy coal status corresponding to each coal bin, and then a coal shifting control instruction can be generated based on the legacy coal bin, and the coal feeder can be controlled to execute the coal shifting control instruction.

[0084] Among them, the legacy coal bunker is a coal bunker where the coal has not been completely knocked out by the coal feeder; the coal knocking control instruction is an operating command used to control the operation of the coal feeder, which includes various parameters of the coal feeder's coal knocking operation in the legacy coal bunker, such as coal knocking speed and other information.

[0085] Specifically, a coal bunker whose coal quantity remaining status is a non-empty state or an un-dug state can be determined as a legacy coal bunker, and the position number of the legacy coal bunker can be determined according to a preset arrangement order. Then, the proportion or weight of the remaining coal in each legacy coal bunker is determined according to the trend of coal quantity changes when the coal feeder passes through the legacy coal bunker, and recorded as the remaining coal quantity. Then, a coal shifting control instruction is generated according to the remaining coal quantity of each legacy coal bunker. For example, according to the position number of the legacy coal bunker in the preset arrangement order and the remaining coal quantity of the legacy coal bunker, the coal shifting speed of the coal feeder when passing through the legacy coal bunker is increased to control the coal feeder to completely shift the coal in the legacy coal bunker within the target time interval.

[0086] In the embodiment of the present application, through the preset arrangement order of multiple coal bins and the remaining coal status of each coal bin, the position number of the remaining coal bin can be determined without the aid of an external position sensor, thereby improving the accuracy and efficiency of determining the remaining coal bin; by determining the remaining coal bin and generating coal shifting control instructions, the coal shifting operation of the coal feeder can be guided in a targeted manner according to the actual coal shifting situation, thereby improving the operating efficiency of the coal feeder and reducing the electricity cost of the coal transportation system.

[0087] S260. Determine the coal feeding effect of the coal feeder according to the remaining coal quantity status corresponding to each coal bunker.

[0088] The technical solution of the embodiment of the present application can obtain the first motion state information of the belt and the second motion state information of the coal feeder, and then determine the relative speed of the coal feeder according to the first motion state information and the second motion state information, and determine the target time interval for the coal feeder to pass through each coal bin based on the relative speed. Regardless of whether the movement directions of the coal feeder and the belt are in the same direction or in reverse, the target time interval for the coal feeder to pass through each coal bin can be accurately determined, thereby improving the accuracy and efficiency of determining the target time interval, and providing an accurate data basis for the subsequent determination of the residual state of coal quantity in each coal bin; then obtain the coal quantity data detected by the metering equipment within the target time interval, and then determine the coal quantity change trend within the corresponding target time interval according to the coal quantity data, and determine the coal quantity residual state of the corresponding coal bin according to the coal quantity change trend. The trend of the coal quantity data measured by the belt scale over time can accurately determine the The coal quantity legacy state, that is, the step trend of the coal quantity data measured by the belt scale over time, is used as a direct reference quantity for feedback to the coal feeder's coal shifting effect on each coal bunker, thereby improving the efficiency and accuracy of determining the coal quantity legacy state of each coal bunker; thereafter, the coal shifting effect of the coal feeder is determined according to the coal quantity legacy state corresponding to each coal bunker, without the need to install any additional sensors on the belt and the coal feeder. The coal falling information of each coal bunker can be accurately monitored through the preset arrangement order of multiple coal bunkers, the coal quantity data measured by the metering equipment, the first motion state information of the belt and the second motion state information of the coal feeder, thereby improving the accuracy and efficiency of determining the coal shifting effect, helping to guide the coal shifting operation of the coal feeder, thereby improving the operating efficiency of the coal feeder, reducing the electricity cost of the coal transportation system, and enhancing the competitiveness of thermal power companies, which is of great significance to the realization of digitalization and intelligence and promoting the high-quality transformation and development of the thermal power sector.
