Hardware-hysteresis-circuit-based method for realizing autonomous thermal control function

The invention relates to a hardware-hysteresis-circuit-based method for realizing an autonomous thermal control function. The method is characterized in that reference signal circuits 1, 2, 3, control circuit reference voltage circuits 1, 2, 3, sensor voltage-stabilizing conversion circuits 1, 2, 3, temperature hysteresis control circuits 1, 2, 3 and a one-out-of-three circuit are arranged. Output terminals of the reference signal circuits 1, 2, 3 are connected with input terminals of the control circuit reference voltage circuits 1, 2, 3 and the sensor voltage-stabilizing conversion circuits 1, 2, 3; output terminals of the control circuit reference voltage circuits 1, 2, 3 and the sensor voltage-stabilizing conversion circuits 1, 2, 3 are connected with input terminals of the temperature hysteresis control circuits 1, 2, 3; output terminals of the temperature hysteresis control circuits 1, 2, 3 are connected with an input terminal of the one-out-of-three circuit; and an output terminal of the one-out-of-thr
