基于乘客状态的电梯群控策略

Elevator Group-control Tactic Based on Passenger Status

提出了一种基于乘客状态的电梯群控策略.该群控策略指出一次乘梯活动是指乘客的状态由就绪状态到完成状态的完整连续过程.结合目的层预约概念,能提前获得乘客的目的层信息.这样,群控策略能为每个乘客指定最优乘坐电梯号,缩短了乘客的候梯时间和乘梯时间.乘客在乘梯活动中被分成4个状态,通过乘客状态来跟踪乘客行为.同时设计了4个工作队列,以方便派梯中心对乘客的管理.仿真实验证明该群控策略可得到很好的效果.采用群控的电梯系统与未采用群控的电梯系统相比,在效率和耗能上均有很大的改善.

Analyses an elevator group-control tactic which describes the passenger journey activity based on the status of passenger. The elevator group-control tactic defines that the passenger journey activity includes the whole time from waiting time to unloading time and the passenger status goes through ready to completion status. Using the destination registration and the status information of passenger, the dispatching control center obtains the passenger＇s destination information in advance and helps the passenger to get the optimal elevator. So the policy can shorten the passenger waiting time and the passenger journey time. The passenger status information, including ready, waiting, running and completion status, can assist to follow the tracks of the passenger＇s action in the whole journey activity. And the dispatching control center administers the passenger＇s requests conveniently by four designed working queues. Simulation results show that the proposed policy is of great performance. Moreover, compared with the traditional elevator policy without groupcontrol, the proposed policy behaves better in efficiency and power consumption.
