Description

Method for correcting influence of moisture content on mineral parameter measurement based on knowledge graph Technical Field The invention relates to the technical field of mineral parameter measurement, in particular to a method for correcting the influence of moisture content on mineral parameter measurement based on a knowledge graph. Background The influence correction of the moisture content on the mineral parameter measurement based on the knowledge graph refers to synchronously acquiring mineral physical parameter signals and corresponding moisture content information through an intelligent sensing system in the mineral parameter detection process, carrying out structural expression on the association relationship among mineral types, component characteristics, moisture state, sensing response characteristics and historical measurement deviation in the form of the knowledge graph, and carrying out association reasoning and dynamic correction on systematic measurement deviation introduced by moisture change on the basis. According to the method, a correlation network between mineral-moisture-measuring results is built by means of multisource sensing data instead of single experience coefficients or static compensation, so that an intelligent sensing system can identify a specific influence path of a current moisture state on a mineral parameter signal in a real-time measuring process, and accordingly, original measuring results are corrected in a targeted manner, and stable representation and consistent output of mineral parameters under different moisture conditions are achieved. The prior art has the following defects: Under the prior art conditions, in the process of correcting the moisture influence of the measurement results of mineral parameters, micro-scale moisture retention areas formed by micro-pore structures or micro-cracks often exist inside the minerals. After the external environmental moisture condition changes and gradually recovers to be stable, the surface moisture signal acquired by the intelligent sensing system is in a stable state, but the corresponding physical response in the mineral is still evolving continuously due to the obvious time delay of the release of the moisture in the retention area. In the prior art, a knowledge graph correction mechanism generally updates the association relation according to the change result of the external moisture signal, and fails to effectively identify and distinguish the internal moisture release hysteresis effect of the mineral, so that the correction reasoning process is continuously triggered under the condition that the external moisture state is stable, and the correction operation is repeatedly overlapped on the internal response which is not completely attenuated, thereby causing continuous excessive adjustment of the mineral parameter measurement result in the time dimension and reducing the reliability and stability of the measurement result. The above information disclosed in the background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.
