Abstract: A lubrication detection method includes a first step is a lubricator provides an information to a processor, a second step is to detect temperature information within a predetermined time period and then to create a temperature curve and then to determine whether or not the recess in the temperature curve faces upward, and a third step of detecting a start point temperature value to form Value A, and averaging temperature values within ⅓ time period in front of the lowest point to form Value B, and average temperature values after ⅔ time period in back of the lowest point to form Value C, and determining whether or not Value B is smaller than Value A, and then determining whether or not Value B is smaller than Value C, and then generating an information of “Normal” indicative of normal lubrication.
