Coal mine underground personnel and material dispatching method based on digital twinning

Abstract

The invention discloses a coal mine underground personnel and material dispatching method based on digital twinning, and the method comprises the following steps: S1, constructing a digital twinning model of a coal mine underground personnel and material dispatching system; s2, updating the digital twinborn model of the underground coal mine personnel and material dispatching system to obtain a real-time synchronous digital twinborn model of the underground coal mine personnel and material dispatching system; and S3, based on the real-time synchronous digital twinborn model of the underground coal mine personnel and material dispatching system, carrying out dispatching prediction by constructing a logistics model and a transportation model, predicting the personnel and material dispatching process of the target transportation system in the next day, and carrying out diagnosis and reasoning on the dispatching situation according to a prediction result in combination with an expert fault diagnosis system. And making an adjustment plan of the current scheduling strategy of the target transportation system. The method has the advantages that the defects that an existing coal mine underground personnel and material dispatching method cannot reflect the personnel and material dispatching process in real time, and the material demand prediction precision is not high enough are overcome; and the obtained scheduling result is analyzed and deduced based on the fed-back real-time data, so that the existing scheduling strategy can be adjusted in time, and the scheduling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of personnel and material scheduling in coal mines, in particular to a method for scheduling personnel and materials in coal mines based on digital twins. Background technique [0002] Coal resources are the basic guaranteed energy in our country, and the production efficiency of mines directly affects the supply of energy in our country. The dispatch of coal mine transportation system runs through the whole process of mine production, and its dispatch quality determines the mine production efficiency. With the development of the coal industry and the increase in the demand for coal, the development scale of underground coal mines in various regions continues to expand, the number of personnel, materials, and equipment to be transported gradually increases, and the number of transportation vehicles required also gradually increases. However, due to the narrow underground roadway, many forks, and limited spa...

Problems solved by technology

Although predictive scheduling can optimize scheduling strategies to a certain extent, predictive scheduling also has some shortcomings: the working mechanism of predictive scheduling is simple, based on grass-roots production data, and requires dispatchers to manually collect, report and summarize, and the scheduling process requires manual Intervention scheduling makes it difficult to realize intelligent scheduling; after the dispatcher gives the transportation order, the driver chooses the route he is familiar with to complete the transportation task based on his own experience

It will inevitably lead to over-occupancy of some transportation lines and low utilization rate of some lines in the transportation process; the dispatcher cannot track the operation status of the mine car in real time, and the mine car driver cannot obtain the operation status of other mine cars before and after the running line, which will inevitably lead to Low scheduling efficiency, easy to cause transportation accidents
