[0002] Coal transportation refers to the transportation process of coal from the production site to the consumption site, including links such as plan formulation, organization and dispatching, and implementation monitoring. Coal transportation should meet the requirements of the unit's safe production for coal quality and ensure the quantity of coal required for production. Coal transportation personnel should organize and adjust the quantity and types of coal in stock in a timely manner according to the dynamic situations such as coal supply, consumption, and inventory, and ensure the continuous and stable supply of coal on the premise of meeting the coal quality requirements of the boiler. Therefore, accurately predicting the quantity of coal in stock is of great significance for ensuring energy supply, optimizing production dispatching, and reducing operating costs.

[0003] Existing coal transportation methods mainly rely on simple mathematical models or empirical formulas to predict future coal inventory demand. Although this method can provide reference information to a certain extent, it has obvious limitations. First, these traditional mathematical models or empirical formulas often only consider current influencing factors and ignore the role of long-term trends; second, they fail to fully utilize the rich information contained in historical data, such as the change law of coal consumption in the past time period and the adjustment of supply-demand relationships in a specific time period, which makes the prediction results relatively single and inaccurate.

[0019] The following is a description of the preferred embodiments of the present invention in conjunction with the drawings.

[0020] As Figure 1 shown, an embodiment of the present invention discloses a daily update method for a coal transportation plan, including: S110: Preset a historical data collection time interval, and collect multiple historical coal transportation situations at the coal conveying point based on sub-historical data collection time points within the historical data collection time interval, where the historical coal transportation situations include historical coal inventory and historical actual coal transportation volume; In this embodiment, the historical data collection time interval can be set according to actual needs, and here it is preferably 14 days, that is, the day before receiving the daily update instruction is taken as the first day, and so on, for 14 days.

[0021] In this embodiment, there are multiple sub-historical data collection time points within the historical data collection time interval. As described above, each day is used as a sub-historical data collection time point. The first day is a sub-historical data collection time point, the second day is a sub-historical data collection time point, and the rest are not listed one by one. 14 groups of historical coal transportation situations can be collected.

[0022] In this embodiment, the historical coal inventory refers to the coal inventory at the coal conveying point on the current day, and the historical actual coal transportation volume is the actual coal transportation volume on the current day. For example, the coal inventory is 10 tons and the historical actual coal transportation volume is 8 tons.

[0023] S120: Determine multiple historical coal transportation difference amounts according to the historical coal transportation situations, perform discrete analysis on all the historical coal transportation difference amounts, and calculate the historical coal transportation discrete coefficient of the coal conveying point based on the discrete analysis result, where the historical coal transportation difference amount is the absolute value of the difference between the historical actual coal transportation volume and the historical coal inventory; In some embodiments of the present application, when determining multiple historical coal transportation difference amounts according to the historical coal transportation situations, performing discrete analysis on all the historical coal transportation difference amounts, and calculating the historical coal transportation discrete coefficient of the coal conveying point based on the discrete analysis result, it includes: Analyze the historical coal transportation situations at each sub-historical data collection time point.

[0026] In this embodiment, if the historical coal inventory is 10 tons and the historical coal transportation amount on that day is 10 tons, but a coal transportation demand of 3 tons is still received, then the actual historical coal transportation amount is recorded as 13 tons, that is, there is a shortage of 3 tons, and the corresponding historical coal transportation difference amount is 3 tons.

[0027] The beneficial effects of the above technical solution are: By dividing the remaining historical coal transportation difference amount array, the best historical coal transportation difference amount array, and the insufficient historical coal transportation difference amount array, the present invention provides an analysis basis for discrete analysis, ensuring the analysis efficiency and analysis accuracy of discrete analysis.

[0029] In this embodiment, calculate the average value of the historical coal transportation difference amounts in the remaining historical coal transportation difference amount array, and use it as the average value of the remaining array.

[0030] In this embodiment, first determine whether there is an average value of the remaining array in the remaining historical coal transportation difference amount array. If so, determine the first remaining difference amount array according to the minimum remaining historical coal transportation difference amount and the average value of the remaining array, and determine the second remaining difference amount array according to the average value of the remaining array and the maximum remaining historical coal transportation difference amount, where the first remaining difference amount array includes the average value of the remaining array, and the second remaining difference amount array does not include the average value of the remaining array. If not, the first remaining difference amount array does not include the average value of the remaining array, and the second remaining difference amount array does not include the average value of the remaining array.

[0031] In this embodiment, determine the quantity of the first remaining historical coal transportation difference amounts and the quantity of the second remaining historical coal transportation difference amounts according to the above judgment results.

[0032] In this embodiment, the analysis process of the first insufficient difference quantity array and the second insufficient difference quantity array is the same as that of the above-mentioned first remaining difference quantity array and the second remaining difference quantity array, and will not be repeated here.

[0033] The beneficial effects of the above technical solution are as follows: According to the first remaining historical coal transportation difference quantity, the second remaining historical coal transportation difference quantity, the first insufficient historical coal transportation difference quantity, the second insufficient historical coal transportation difference quantity, and the best historical coal transportation difference quantity, the present invention calculates the historical coal transportation dispersion coefficient of the coal transportation point, effectively ensuring the calculation accuracy of the historical coal transportation dispersion coefficient, and at the same time providing a basis for calculating the historical coal transportation comprehensive coefficient in one aspect.

[0036] In this embodiment, the historical actual coal transportation volume curve is constructed on a rectangular coordinate system, which includes the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant.

[0037] In this embodiment, the historical coal inventory is fitted with the historical actual coal transportation volume one by one. That is to say, for each abscissa, there is first a historical actual coal transportation volume, and second, there is a historical coal inventory corresponding to it. The historical coal inventory corresponds to the historical actual coal transportation volume. Among them, the historical coal inventory curve may be a straight line or not, and it can be constructed according to the actual situation.
