2) the more floor of intelligent's number is predicted.
When obtaining the history data of elevator, and being specified according to history data and current operating data prediction future
Number is gone in the request of interior each floor, and request is taken to go to top n floor often as peak floor.
As shown in Figure 2, it is predicted that the detailed process of the more floor of intelligent's number is as follows:
2.1) current operating data of elevator is obtained.
2.2) obtain specified time window in elevator history data, data content include but is not limited to departure floor,
Purpose floor, set out request time and boading time.
Wherein, acquired history data are as follows: carry out data statistics by a cycle of Monday to Sunday, determination is worked as
It in the cycle belonging to the period, obtain be located at different cycles in and period corresponding data as history data.
Under normal circumstances, substantially stationary for the commuter time of the company in same building, therefore the passenger-in-elevator of every day
Circulation of this presentation of base as unit of some cycles, it can tissue is carried out according to the date of historical data.Such as: each
The data in week are separately stored, and determination is currently Tuesday, are then obtained different weeks in historical data but are also the data of Tuesday
As history data.
In other embodiments, the statistics of historical data can also be with the moon or be counted with other times, and in order to
Avoid interference of the burst data to prediction result, the available multiple groups of history data.
2.3) similarity of the current operating data of elevator and the history data in the time window of acquisition is calculated.

It is fixed.The relationship of the quantity N of peak floor and the quantity of lift car are set in the present embodiment are as follows:
Certainly, in order to embody the present embodiment elevator control method effect, which is typically employed in elevator car
The case where quantity in compartment is more than or equal to 4.Even lift car quantity is 4, then the quantity of peak floor can be 2 layers.?
In other embodiments, the ratio of the quantity of the quantity and lift car of peak floor can also be 1/3 or 1/4 etc..
In another embodiment, predict that the method for floor arrival number can also calculate acquisition otherwise, such as
A recursive neural network can be designed to realize.The method for changing prediction floor arrival number can not influence to invent institute's energy
The effect of generation and the purpose that can reach.
3) performance indicator that each lift car goes to purpose floor indicated by current request is calculated, and according to performance indicator pair
Each lift car is ranked up to obtain performance sequence.
Performance indicator includes waiting terraced time, riding time or elevator energy consumption.When carrying out lift car performance Index Calculation,
Can choose etc. in terraced time, riding time and elevator energy consumption this three one of calculate；It can also be by weight come group
Close these indexs, such as: settable to wait ladders when the current equal terraced time for reducing passenger is elevator control system most urgent target
The weight of this index of time is 0.8, and the weight of other two indices is 0.1.
Equal terraced time and riding time in performance indicator need to be closed according to the departure floor of request and elevator current location
System is calculated.
As shown in figure 3, waiting the calculating of terraced time, comprising:
By taking upstream request as an example, if the direction that request is gone to is identical as the current traffic direction of elevator, and elevator is operated in out
The rear of floor is sent out, then waits the terraced time to be equal to elevator and (is numbered in such as Fig. 3 from the runing time that current location runs to departure floor
Shown in floor for 13)；Otherwise, it waits the terraced time to be equal to elevator to run in the service queue of lift car most from current location
Remote floor returns the runing time for issuing floor (as shown in the floor that number is 14~18 in Fig. 3).
The case where the case where downbound request is with upstream request is identical, is no longer repeated.
The calculating of riding time, comprising:
The time that passenger enters lift car is denoted as boading time, when the time that passenger goes out lift car is denoted as descending stair
Between, then difference of the riding time between descending stair time and boading time.
Elevator energy consumption is related with the stop number of elevator, can estimate by the stop number for reaching target zone, and elevator
Stop number it is more, elevator energy consumption is bigger.
4) the stop number in the service queue of each lift car is calculated.
The stop number being located in the service queue of each lift car of departure floor indicated by current request is calculated, and
Query service is directed to the response result of current request in the lift car of peak floor.
In order to reduce the equal terraced time of passenger, preferably from each lift car for being located at departure floor indicated by current request
In assigned.If departure floor of each lift car not indicated by current request directly calculates each lift car and arrives
The time required to the departure floor, and choose the shortest lift car response current request of required time.
5) it carries out sending ladder according to the stop number whether response current request changes lift car.
By taking the mode of up peak as an example, elevator group needs for the passenger for entering building first layer hall to be successively transported to respectively
From purpose floor.Wherein, an influence waiting time and an important factor for these performance indicators of riding time are exactly stopping for elevator
By number.This is because there is primary stop in a lift car for being loaded with passenger, then open and close door and upper and lower passenger when stopping
Time can all increase waiting all passengers of the ladder waiting time, also will increase the riding time of passenger in carriage.Therefore,
Reducing and stopping number is the effective means that can promote team control performance indicator.Especially, if certain elevator service is in those
Reach the floor more than number, then measure whether the elevator is used for the new request of response just should be not increase this elevator
Number is stopped as essential condition.
Therefore the preferential query service of the present embodiment is in the response result of the lift car of peak floor, if response result is not increase
Add stop number, then corresponds to lift car response current request；If being currently serviced in the response knot of the lift car of peak floor
Fruit is to increase to stop number, then never serves in the lift car of peak floor according to the best electricity of performance sequence selection
Terraced carriage response current request.

It is assumed that there are 4 elevators and multiple floors.The scene of one application is according to before the request
The 7th layer and the 4th layer of the lower a moment floor most for arrival number is predicted in service queue.
And the lift car that number is A, at the 1st layer (lift car shown in label 19 in Fig. 4), which has distributed to
Toward the 7th layer of request.The lift car that number is C is at the 1st layer (lift car shown in label 20 in Fig. 4), and the carriage has been divided
Dispensing goes to the 4th layer of request.The lift car that number is D is at the 1st layer (lift car shown in label 21 in Fig. 4), and the sedan-chair
Compartment, which has been distributed to, goes to the 8th layer of request.For the lift car that number is B at the 8th layer, which is currently at downstream state.
If a passenger goes to the 7th layer of request in one layer of hall sending at this time, this request will preferentially task A
Carriage response because this request of A carriage response does not increase its stop number for going to purpose floor (the 7th layer), and with its mesh
Floor it is identical.
If a passenger goes to the 6th layer of request in one layer of hall sending at this time, this request will not task sedan-chair
Compartment A, because this request of carriage response will lead to the stop number that it goes to purpose floor (the 7th layer) and increase.It goes out toward the 6th layer
Request can distribute to carriage C because this request of C carriage response does not increase its stop for going to purpose floor (the 4th layer)
Number.
If a passenger goes to the 3rd layer of request in one layer of hall sending at this time, this request will not task sedan-chair
Compartment A, because this request of carriage response will lead to the stop number that it goes to purpose floor (the 7th layer) and increase.Equally will not
Carriage C is distributed to, because this request of C carriage response will increase its stop number for going to purpose floor (the 4th layer).It leaves for
D carriage can be distributed to toward the 3rd layer of request, goes to purpose floor (the 8th layer) although distributing to D carriage and will lead to D carriage
Number is stopped, but the allocation plan is best from the point of view of equal ladder time.
