The invention relates to an elevator debugging method, an elevator debugging system and an elevator system. The elevator debugging method includes the steps of obtaining at least one operation datum of at least one elevator door, comparing the operation data with corresponding benchmark operation data, judging whether the deviation between the operation data and the benchmark operation data exceeds a preset range or not, and if yes, triggering the control over at least one control terminal related to the operation of the elevator doors to make the deviation between the regained operation dataand the benchmark operation data located within the preset range. By means of the method, the elevator debugging efficiency can be greatly improved, the adverse effects caused by the 'chimney effect'and other factors on the operation of an elevator are solved, and therefore it is ensured that the elevator has a good operation state and high safety.
