Detection method and system based on bearing temperature test under different working conditions, and medium

The invention provides a bearing temperature test detection method and system based on different working conditions and a medium, and the method comprises the steps: obtaining the parameter information of a to-be-detected bearing, determining the first contact area information according to the first quality information, the third quality information and the first instantaneous temperature information, and determining the second contact area information, determining first detection feature information according to the first instantaneous temperature information and the first contact area information, and determining second detection feature information according to the second instantaneous temperature information and the second contact area information; the method fully considers the influence of the contact area, which is an important factor between the components in the rolling bearing, on the heat transfer relationship, truly simulates the measurement of the temperature of the bearing under different loadin
