Vertical dispatch method for double sub-elevator groups for energy saving

Abstract

The invention discloses a vertical dispatch method for double sub-elevator groups for energy saving, and relates to a vertical dispatch method for double sub-elevator groups. The method aims to adapt to the dispatch of double sub elevators for meeting the requirement of passenger flow changing and different floors. The method comprises the following steps of: carrying out collection on an elevator calling signal of a passenger; according to the collected information of the elevator calling signal, a car operating status and the like, analyzing a current traffic mode; applying a genetic algorithm to realize a dynamic sub-region control strategy, and generating an initiate group; decoding an individual, and calculating an individual application degree value; judging whether the individual with the highest application degree satisfies the operation rule of double sub elevators or not, if yes, further judging whether a final condition is met, if no, abandoning the individual, and carrying out genetic operation; and selecting the next generation, carrying out crossing and variation, calculating the individual the individual application degree value of a new generation, repeatedly implementing the genetic operation until meeting the final condition, and responding to passenger calling with an elevator dispatch scheme of a final individual. The vertical dispatch method is applied to the vertical dispatch of the double sub-elevator groups.

Description

technical field [0001] The invention relates to a vertical scheduling method for a twin elevator group. Background technique [0002] At present, the existing elevators in the world are mainly single-well single-lift elevators (that is, there is only one elevator in one well), and the elevators in multiple wells in the same building form an elevator group control system, which leads to the traditional elevator scheduling problem. But the twin elevator that this invention relates to is a brand-new object---the twin elevator system, and schematic diagram is attached figure 1 As shown, the twin elevator system usually consists of floors, elevator shafts, elevator cars, and car storage. The characteristic of twin elevators is that there are multiple elevators in one well, that is, two elevators follow the same guide rail, and one is superimposed on the other, but they both operate independently of each other and influence and restrict each other. Therefore, the twin elevators ...

Problems solved by technology

[0003] There are many traditional elevator group control scheduling methods, but the twin elevators are a brand-new object, and its group control scheduling method has just started. At the same time, the group control scheduling algorithm is only based on simple operating rules and integrated with intelligent algorithms for scheduling. For example, foreign Japanese Patent JP2007055692 discloses a single-shaft multi-car elevator group control system. By predicting the running status of each car and combining with the best control strategy in history, the group control system performs elevator dispatching operations, but the algorithm convergence speed is slow and cannot be very good. Adapt to changes in passenger flow and the needs of different floors
