Intelligent elevator system

Abstract

An intelligent elevator system is composed of a PLC, a frequency converter, a tractor, a rotary encoder, a car, a weighing module and a signal module. The R, P and S terminals of the frequency converter are electrically connected with a three-phase power supply through a rectifier filter circuit and an air switch SA. The tractor is electrically connected with the frequency converter through a contactor KM. The tractor is in signal connection with the frequency converter through the rotary encoder. The frequency converter is in signal connection with the PLC. The signal module and the contactorKM are in signal connection with the PLC. The signal module is composed of a floor invitation signal module, an in-car control signal module, signals of a weighing module and a floor monitoring camera signal module. Signals of the floor invitation signal module and signals of the floor monitoring camera signal module jointly form a basis for the PLC to judge whether the elevator car parks at thefloor or not. Compared with the prior art, by the adoption of the intelligent elevator system, an elevator does not stop and continues to run even when an invitation signal exists but no passenger exists, so that the operation time of the elevator is saved, and the power consumption is reduced.

Description

technical field [0001] The invention relates to an elevator, in particular to an intelligent elevator system. Background technique [0002] As we all know, the current large-scale office buildings are generally equipped with multiple elevators. Sometimes the passengers will press the signal keys of multiple elevators at the same time. There is a shortcoming that other elevators will still stop the car when they reach the floor, but no one takes the elevator after the car stops, resulting in a waste of elevator running time and electric energy and the service life of the elevator. Therefore, it is necessary to design an intelligent elevator system in which the elevator does not stop and continues to run even if there is an invitation signal but there are no elevator passengers. It is a technical problem that needs to be solved at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent elevator sy...

[0002] As we all know, the current large-scale office buildings are generally equipped with multiple elevators. Sometimes the passengers will press the signal keys of multiple elevators at the same time. There is a disadvantage, that is, other elevators will still stop the car when they reach the floor, but no one takes the elevator after the car stops, resulting in the waste of elevator running time and electric energy and the service life of the elevator.
