sequentially acquiring real-time measurement data of the sensors which are arranged in the labyrinth mounting holes (301), the first spacing ring mounting holes (302), the second spacing ring mounting holes (303) and the third spacing ring mounting holes (304) and are not monitored;
comparing the real-time measurement data of the sensor with the pre-measurement data of the grease with different slag feeding degrees to obtain a comparison result;
judging the slag entering degree of the grease according to the comparison result;
and if the slag inlet degree of the grease is higher than a preset threshold value, determining a main driving slag inlet position according to the sensor setting position.
11. The method as recited in claim 8, further comprising:
and determining treatment measures according to the slag inlet degree of the grease in the main drive, wherein the treatment measures comprise cleaning slag stones and/or replacing sealing rings.
12. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method of any of claims 8 to 11 when executing the computer program.
13. A computer readable storage medium, characterized in that the computer readable storage medium stores a computer program which, when executed by a processor, implements the method of any of claims 8 to 11.
14. A computer program product, characterized in that the computer program product comprises a computer program which, when executed by a processor, implements the method of any one of claims 8 to 11.
