The present invention provides a self-checking device and method for an elevator braking device and an elevator system. The self-checking device comprises: an inductance testing module configured to measure an electromagnetic brake coil (5) inductance L of the braking device; and a processing module electrically connected to the inductance testing module, and storing a mathematical model of an air gap a between the movable plate (2) and the static plate (1) with respect to the brake coil (5) inductance L in a brake state; wherein, the processing module is configured to execute a checking mode in the brake state of the braking device, and in the checking mode, the processing module receives a current inductance L0 measured by the inductance testing module, calculates a current air gap a0 based on the mathematical model stored, and determines a wear degree of the friction lining (3) based on the current air gap a0 calculated.
