The invention particularly relates to an elevator operation control method and system based on a vibrating sensor and an elevator. The elevator operation control method comprises the following steps: obtaining first preset time according to an operating speed of the elevator; according to the time spent in judging whether a person waits for the elevator or not by adopting a vibration signal detection method, correcting the first preset time to generate second preset time; and when the time before the elevator arrives at the floor where the elevator will stop is the second preset time, judging whether a person waits for the elevator or not at the floor where the elevator will stop by adopting the vibration signal detection method, and correspondingly controlling the elevator. According to the invention, during an operational process of the elevator, by detecting whether a person waits for the elevator or not at the floor where the elevator will stop, the elevator is controlled to move straight when no person waits for the elevator, so that the situation that no person gets on the elevator after the door of the elevator is opened is avoided, the operation efficiency of the elevator is improved, the riding time of elevator passengers is shortened, and the riding feeling of a user is improved.
