The invention discloses a safety circuit detection method, device and equipment and a storage medium. The method comprises the steps that multiple current values of a safety circuit of an elevator are collected; arranging the current values into a first current array in a historical detection period; extracting the characteristics of the current in the safety loop from the first current array to serve as current characteristic values; identifying the type of the current in the safety loop according to the current characteristic value; setting a detection threshold adaptive to the type of the current for the safety circuit according to the current characteristic value; and in the current detection period, the current value is compared with a detection threshold value so as to detect the state of the safety loop. The detection threshold value is dynamically set according to the actual condition of the current in the safety circuit of the elevator, the adaptation degree between the detection threshold value and the actual condition of the current in the safety circuit of the elevator is improved, and the conditions that the current of the safety circuit fluctuates along with time, components of the safety circuit age and the like can be adapted; and the accuracy of detecting the state of the safety circuit of the elevator is improved.
