Fig. 4 is a schematic diagram of an algorithm for automatically generating a dispatching plan of a hot-metal ladle according to the present invention, and the implementation manner is as follows: 1) the system converts the data collected by a liquid level meter arranged in the iron making into the weight data of the molten iron tank, when the weight of the iron receiving heavy tank of the iron making blast furnace reaches the specified weight (for example, when the iron receiving amount reaches 30% of the rated load), the iron receiving heavy tank is placed into a heavy tank pool to become the heavy tank to be distributed (the reason that the less than full molten iron tank is placed into the heavy tank pool is that a certain foresight is needed by a molten iron dispatching plan, and the time is too late when all the molten iron tanks are filled and then the regeneration plan is carried out). Similarly, the system converts the data collected by the liquid level meter arranged in the steel making process into hot metal charging weight data of the hot metal tank, and when the hot metal charging weight of the iron making blast furnace reaches the specified weight (for example, the hot metal charging amount reaches 50% of the rated load), the hot metal charging weight data is put into the empty tank pool to become an empty tank to be distributed. 2) And (3) sequencing the foundation pits (needing to be refilled) of the converter dumping stations of the steelmaking and the iron-making blast furnaces (needing to be emptied) according to the requirements to form a taphole requirement queue and a foundation pit requirement value queue, wherein the hot metal ladle can be selected in a refilled ladle pool and an emptied ladle pool with the highest requirement value. The iron notch of the iron-making blast furnace and the foundation pit of the steel-making reladling station are main bodies of requirements, the purpose of the molten iron dispatching plan is to allocate the molten iron tank meeting the conditions to a correct main body of requirements, and the required value of the main body of requirements is calculated according to the existing stock of the main body consumables (namely the existing molten iron quantity of the steel-making converter and the existing empty tank capacity of the iron-making blast furnace), the planned ration (which refers to the part of the consumables which are planned to be allocated but not converted into the existing stock) and the artificially-specified requirement weight value of each main body of requirements by an enterprise according to the self operation characteristics (such as the condition that a certain main body of requirements is preferentially satisfied, and a certain main body of requirements. 3) The method for selecting the hot metal ladle in the ladle pool by the demand main body with the highest demand value includes the steps of firstly filtering out the hot metal ladles which do not meet the conditions (such as high-quality molten iron required by a converter for steelmaking, empty ladles of a certain type required by a blast furnace for ironmaking and the like) according to the filtering rules of the demand main bodies, and enabling the filtered hot metal ladles to become the alternative ladles of the demand main bodies. 4) After the alternative tanks are selected, if the requirement of the number of the grouped tanks of the railway (such as one set of 2 tanks of the torpedo tank and one set of 8 tanks of the open tank) is met, a hot metal tank scheduling plan can be generated immediately, if the requirement is not met, a period of time is required to wait until a new alternative tank is selected, or the alternative tank is completely full or emptied, and then the scheduling plan generation is started (the time from half full to full of a heavy tank and half empty to empty of an empty tank is used as the buffer time for generating the scheduling plan, which is one of the characteristics and advantages of the invention). 5) And according to the destination of the hot metal ladle specified by the generated hot metal ladle dispatching plan, automatically generating a shunting plan by combining the current position of the hot metal ladle, and automatically issuing the shunting plan to the vehicle-mounted equipment in the locomotive cab for displaying and printing.
