presetting the iron content data of the waste lubricating grease at different levels in the lubricating grease controller, and setting the threshold range of the iron content of the waste lubricating grease;
when the iron content of the lubricating waste grease reaches the threshold range, the lubricating grease controller starts counting and enters an automatic regulation state;
when the iron content of the lubricating waste grease exceeds a preset threshold value and reaches a range of grease supplement, sending a grease supplement instruction, and transmitting the grease supplement instruction to a lubricating drive;
and the lubricating drive automatically opens a valve connected with a lubricating grease storage tank, so that the lubricating grease finger is automatically supplemented, and the supplementing time is counted.
9. A control arrangement for bearing grease according to claim 6 wherein the grease detection module includes a booster for carrying the detected grease to a connecting line and clearing a bypass.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 5.
