The invention relates to a detection method and device for an elevator star sealing circuit. The method comprises the steps that a first periodic signal is obtained; acquiring a first feedback signal; the first periodic signal is a detection signal output by the driving unit; the first feedback signal is a feedback signal generated by a normally closed contact of the star sealing contactor on the basis of the first periodic signal; and based on the first periodic signal and the first feedback signal, judging whether a normally closed contact pair of the star sealing contactor is conducted or not. By means of the elevator star sealing detection method and device, the technical problem that whether the star sealing function of an elevator fails or not cannot be accurately judged in the prior art is solved, a complex adhesion detection circuit does not need to be arranged, the hardware cost is low, the accuracy of elevator star sealing detection is improved, and then the safety of the elevator is improved. 本申请涉及
