In the existing elevator structure, after a landing is registered in a car, an elevator runs to a corresponding floor to stop according to registered floor data, and the elevator only runs according to the registered floor data and has no direct relation with whether a driver or a passenger exists in the car; in this way, there is a possibility that the elevator runs in a no-load state due to the fact that landing information is registered by misoperation or artificial intentional misleading and no passenger gets on the elevator, and elevator resources are wasted. Particularly, when a plurality of landing information is called and registered in the elevator and the elevator runs in a no-load mode, the base station personnel call the elevator, the elevator still needs to wait until the elevator stops at all registered floors and automatically closes the door until the elevator responds to the call of the base station personnel, and the time of waiting for the elevator personnel is greatly wasted.
In the conventional tamper-prevention technology, for example, when the detected weight is less than a certain value based on the weight, floor information other than the most recently called floor information is cancelled, but if the floor registered in no-load is the highest floor, a large amount of time for waiting the elevator is still wasted particularly when the number of floors is extremely large.
