Wherein, as is easily understood by those skilled in the art, if the fit degree of the elevator door vane 15 and the elevator door ball 16 is poor, the gap between them is not uniform, and the sway of the elevator during the operation of the elevator system is likely to cause the collision between the elevator door vane 15 and the elevator door ball 16, thereby causing the sudden stop of the elevator car 20 during the operation. If the distance between the elevator door knife 15 and the ground chop does not meet the spacing standard, for example, the distance between the elevator door knife 15 and the ground chop is less than 5mm, after the elevator is used for a period of time, the elevator guide shoe 17 is worn and loosened, so that the elevator door knife 15 can be collided with the ground chop when the elevator car 20 is in operation, and the problem that the elevator door knife 15 is more than 11mm away from the elevator door ball 16 when the elevator door knife 15 and the ground chop are in operation can occur. In addition, the amount of oil in the oil cup 14 on the elevator guide shoe 17 should be ensured within a reliable capacity range.
In one possible embodiment, the hoistway environment includes the environment of the pit 1 a.
In this embodiment, the maintenance professional or the edge computing gateway 5 may determine whether the elevator component 1 is abnormal by recognizing whether the volume of the accumulated water or the foreign matter in the pit 1a is greater than a preset volume threshold.
