The invention relates to an experimental method for acquiring a pulse duty cycle of electric heating pad pulsed power-up. The experimental method belongs to the technical field of electric heating control, and comprises the steps of: 1) deactivating or dismantling functions of measuring real-time temperature and performing fuse power-off of an existing electric blanket; 2) carrying out pulsed power-up on the existing electric blanket by means of pulse signal control with a plurality of different duty cycles; 3) measuring a plurality of temperature values reached after the existing electric blanket undergoes pulsed power-up; 4) finding out the highest temperature value among the plurality of temperature values, and determining and screening a safe highest temperature value according to experience; 5) finding out a pulse signal corresponding to the safe highest temperature value, and acquiring a duty cycle of the pulse signal. By adopting the experimental method, the duty cycles of the pulse signals corresponding to the highest temperatures which are relatively safe can be selected, and the pulse signals with the duty cycles are used for controlling pulsed power-up of the electric heating pad, thereby providing effective guarantee for the safety of the electric heating pad adopting pulsed power-up.
