Elevator and control method thereof

Abstract

The invention discloses an elevator which comprises an elevator car, a driving unit, a weighing unit, a next stopping determination unit, a speed graph generation unit, a control unit and a maximum load calculating unit. The speed graph generation unit generates an elevator car operating speed graph according to the definite distance of the elevator car operating from the former position to the next stopping floor and the relation between the elevator car actual load and the elevator maximum load. The control unit controls the driving unit according to the speed graph coming from the speed graph generation unit to lead the elevator car to operate according to the speed graph. By adopting the elevator, the number of people waiting for the elevator in the passenger flow peak period can be reduced, the crowded condition of an elevator hall is relieved, the maximum elevator transporting efficiency is achieved, the elevator external environment can be flexibly handled by changing the maximum load in the elevator transporting efficiency and the speed graph, and the elevator waiting time of passengers corresponding to the load upper limit increasing is greatly shortened. The invention further discloses a control method of the elevator.

Description

technical field [0001] The present invention relates to an elevator. The invention also relates to an elevator control method. Background technique [0002] It is an important research topic in the field of elevators to try to improve the transportation efficiency of elevators under given conditions. Elevator transport efficiency is closely related to the load of the elevator car and the running time and displacement during the process of transporting the load to the destination floor. The displacement is determined by the floor where the elevator stops, and generally cannot be changed. Therefore, there are two possible ways to improve the transportation efficiency of the elevator: increasing the load of the elevator car and shortening the running time. [0003] At present, in addition to the group control algorithm applicable to parallel connection of multiple elevators, most of the existing technical solutions applicable to improving the efficiency of elevator transporta...
