A drive system thermal temperature rise detection and compensation system is to install an optical non-contact sensor head on the main shaft of a machine tool, and a sensing center formed in the center of the sensor head, which driven by the transmission device of the machine tool The platform provided with several ball lens devices, and the transmission device providing with a temperature sensor that transmits a temperature data to the outside. The machine tool uses the sensor head to sequentially record the origin coordinates of the centers of the ball lenses. Moving the sensor head to the origin coordinates of each ball lens in sequence, measure the displacement error between the sensor center and the ball lens center due to the thermal displacement of the transmission device. Record the displacement error and temperature data in the A signal processor achieves the functions of automatically recording errors for a long time, high measurement accuracy, and capable of measuring multi-axis errors and temperat
