The invention provides a method for detecting the state of a brake, and the method comprises the steps: adjusting the current in a brake coil of the brake, enabling a brake part of the brake to leave from a first position and move to a second position; collecting a first current of the brake coil when the brake component leaves the position; determining a first electromagnetic force according to the first current and a preset relation model; calculating a second electromagnetic force according to the first electromagnetic force; when the brake component is located at the second position, the current in the brake coil is adjusted to enable the brake component to leave from the second position; collecting a second current of the brake coil when the brake component leaves the second position; and determining a gap from the preset relation model based on the second electromagnetic force and the second current. The invention further provides a corresponding system and an elevator brake.

    本申请提供用于检测制动器状态的方法,其包括:调整用于所述制动器的制动线圈中的电流,使所述制动器的制动部件从第一位置离开,移向第二位置;采集所述制动部件离开所述一位置时所述制动线圈的第一电流;依据所述第一电流,根据预设关系模型确定第一电磁力;根据所述第一电磁力计算第二电磁力;在所述制动部件位于所述第二位置时,调整所述制动线圈中的电流以使所述制动部件从所述第二位置离开;采集所述制动部件离开所述第二位置时所述制动线圈的第二电流;以及基于所述第二电磁力、所述第二电流,从所述预设关系模型确定间隙。还提供相应的系统与电梯制动器。
