Description

Elevator allocation method Technical Field The invention relates to the technical field of elevators, in particular to an elevator allocation method. Background At present, the existing elevator system which is configured with the linkage with the gate is characterized in that a passenger swipes a card (or a face, etc.) at the gate, the gate opens the gate after verifying the identity of the passenger and sends passenger identity information to the elevator, the elevator determines a destination floor according to the passenger identity information, the group control system distributes a response elevator to the passenger according to the current running information of the elevator and the destination floor of the passenger and sends a response elevator identification to the gate (the processes are all completed at the moment of the passenger swipes the card), the response elevator identification is displayed by the gate, the passenger knows the elevator which the passenger should take according to the display content of the gate, and the passenger moves to the response elevator through the gate to wait for the arrival of the response elevator so as to take the elevator. The elevator group control system completes the allocation of the elevator (namely, selecting a response elevator for the passenger) at the moment when the passenger passes through the gate, and the elevator group control system determines the response elevator for the passenger approximately by firstly calculating the passenger moving time required by the passenger to walk to the elevator hall from the gate and determining the passenger arrival time when the passenger arrives at the elevator hall according to the distance between the gate and the center of the elevator hall obtained in advance and the default passenger walking speed (such as 1 m/s), then predicting the influence factors which possibly occur in the passenger moving time and influence the elevator to the floor where the passenger arrives (such as a new call signal possibly occurring between the current floor of the elevator and the floor where the passenger exists, etc.), then estimating the elevator running information (such as the elevator arrival time when the elevator arrives at the floor where the passenger exists, etc.) of the elevator before and after the passenger arrival time according to the passenger arrival time and the elevator running information, and finally allocating the elevator corresponding to the optimal evaluation value as the response elevator according to the passenger arrival time and the elevator running information, and enabling the time interval between the passenger arrival time and the elevator arrival time not to exceed a time threshold. As can be seen from the above description, when the distance between the gate and the elevator hall is small, the passenger moving time required for the passenger to walk from the gate to the elevator is short, so that the difficulty in predicting the influence factors and estimating the elevator running information before and after the arrival time of the passenger by the elevator is low, the accuracy of the prediction result of the influence factors and the estimation result of the arrival time of the elevator is high, and on the other hand, when the distance between the gate and the elevator hall is small, the accuracy of the arrival time of the passenger to the elevator hall caused by the difference between the actual pace of the passenger and the default pace of the passenger is also high, and the obtained elevator allocation result is reasonable. However, when the gate is far from the elevator hall, the passenger movement time required for the passenger to walk from the gate to the elevator is long (e.g., more than 1 minute in an individual scenario), both the accuracy of the prediction result for the influence factor and the estimation result for the arrival time of the elevator, and the accuracy of the arrival time of the passenger to the elevator hall are very low, so that the deployment result obtained by the elevator group control system based on inaccurate information is naturally bad, 1) the response elevator of the passenger arrives at the elevator hall of the floor where the passenger is located too early, resulting in lowering the operation efficiency of the elevator due to too long waiting time of the elevator or the passenger misses the response elevator before the passenger arrives at the elevator hall, 2) the passenger arrives at the elevator hall too early, resulting in too long waiting time of the passenger, or at least one other elevator that can take the passenger and the arrival time of the elevator is earlier than the arrival time of the response elevator. Therefore, how to reasonably allocate response elevators for passengers when the gate is far from the elevator hall is a technical problem.
