Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to elevator group management control, and more particularly to an elevator group management control device suitable for improving transportation capacity on a crowded floor such as during lunch.

[0002]

2. Description of the Related Art Generally, in office buildings, standard floors are crowded during work hours. Also, during the lunch time, the standard floor and the cafeteria floor are mainly crowded. Normally, all elevators are serviced on all floors, but if it is particularly crowded, the service floor is divided into upper and lower floors so that the service is even, and divided express operation is performed. By doing so, the lap time is shortened and the transportation capacity is improved. Also, depending on the building, when you go to work
There are also places that use the staggered cafeteria during lunch to reduce congestion.

By the way, JP-A-59-177264 discloses that
It is disclosed that the zones are divided according to the traffic demand, the services in each zone are equalized, and the services are improved. In addition, in Japanese Patent Laid-Open No. 63-87486, the traffic demand concentration time zone is divided into a plurality of areas, and the service floor is divided into priority floors and non-priority floors. However, it is disclosed that the priority floor is changed according to the divided traffic demand concentration time zones. Also,
Japanese Examined Patent Publication No. 62-36954 describes that the traffic demand between floors is determined from the traffic demand learning result for a predetermined period, but its use is unknown.

[0004]

[Problems to be Solved by the Invention] Traffic demand in a building is not always constant from the time of completion. The number of elevators that was originally appropriate from the number of people in the building may be insufficient due to the increase in the number of people in the building to meet traffic demand. In such a case, the smaller the number of elevators is, the more congestion cannot be solved at lunchtime without more efficient driving. In the above-mentioned conventional technique, even if the zones are divided according to the traffic demand and the services in each zone are equalized as in JP-A-59-177264, there is a limit to the improvement of the transportation capacity. In addition,
As in the 63-87486 publication, if the number of elevators to be serviced is increased on the priority floor where there are many users, deterioration of service on the general floor is inevitable.

An object of the present invention is to reduce the service on non-congested floors such as general floors during a time when there are many users, such as lunch, when the number of elevators is insufficient for traffic demand. The purpose of the present invention is to provide an elevator group management control device for improving the transportation capacity on a congested floor.

[0006]

In order to achieve the above object, in the present invention, the traffic demand for each floor obtained from the learning result of the traffic demand for a predetermined period is detected, and the traffic demand table for each floor is detected. To analyze the data of the floor-to-floor traffic demand table, and to design an operation mode according to the value of the floor-to-floor traffic demand data corresponding to a preset single or plural specific condition. This is achieved by evaluating the planned operation mode, judging whether the operation mode is the same as the current operation mode, and resetting the optimum operation mode.

[0007]

With the above-mentioned configuration, it is possible to set the operation mode according to the traffic demand between floors, and it is possible to improve the transportation capacity especially during the crowded lunch time.

The present invention is not limited to lunch hours, but can be applied to other busy hours.

Further, according to the present invention, the operation mode to be planned can be expanded by changing a preset specific condition using a maintenance tool or the like.

In step SA30, the floor-to-floor traffic demand of the next traffic flow is calculated from the floor-to-floor traffic demand data of the current traffic flow m created in step SA20 and the floor-to-floor traffic demand data of the next traffic flow m1 learned in the past. Predict
Traffic demand forecast work table PTW (f, f) for each floor
Create Here, in order to predict the traffic demand for each floor of the next traffic flow, the current traffic flow m created in step SA20
The inter-floor traffic demand data and the inter-floor traffic demand data of the next traffic flow m1 learned in the past are used, but it is not limited to this, and the next traffic flow m learned in the past is simply used.
You may make a prediction based on the traffic demand data between floors of the traffic flow m1 and the traffic flow m2 one after another. Further, the data of the traffic demand work table PSTW (f, f) for each floor may be included.

A process of resetting the operation mode planned in step SA40 is performed.

FIG. 4 is a flow chart for explaining the operation mode planning process in step SA40 of FIG.

In FIG. 4, step SB10 analyzes the data of the inter-floor traffic demand forecast work table PTW (f, f) created in step SA30 of FIG. Interval (k is the number of elevators)
And the extracted traffic demand data for each floor between the specific floors in descending order of traffic demand work table STW
It is stored in (k) (k is the number of elevators). Specified floor-to-floor traffic demand work table STW (2) stored here
~ STW (k) traffic demand data is compared with STW (1) traffic demand data, and the value of the traffic demand data is, for example, S
STW (n) if half or less of TW (1)
The traffic demand data (n is 2 to k) is deleted. It should be noted that the floor space between the floors with a high demand for inter-floor traffic extracted here is defined as the upper k floor space, but the floor space is not limited to this, and may be fixed to the upper 4 floor space, for example. In step SB20, step S
Work table S for traffic demand between specific floors stored in B10
The sum total of the traffic demand data of TW (1) to STW (k) is obtained, and the inter-floor traffic demand rate PSR between the specific floors with respect to the total sum of the inter-floor traffic demands is calculated by Equation 1.

[0027]

[Equation 1]

In step SB30, the inter-floor traffic demand rate PSR of the specific floor calculated in step SB20 is 1 / k.
If (k is the number of elevators) or more, step SB4
Process 0. In Step SB40, Step SB1
The operation mode in which the direct operation or the skip operation is performed between the specific floors extracted in 0 is planned. In addition, the traffic demand between the specific floors where the direct operation or the skip operation is performed here clears the data of the inter-floor traffic demand forecast work table PTW (f, f) created in step SA30 of FIG. In the following processing, there is no traffic demand between specific floors. In step SB50, the number of elevators k1 that performs a direct operation or a skip operation between the specific floors extracted in step SB10 is calculated by Equation 2.

[0029]

## EQU00002 ## k1 = PSR.times.K (Equation 2) In step SB60, the inter-floor traffic demand forecast work table PTW (f, f) created in step SA30 of FIG.
Based on f), the total traffic demand of the general floors excluding the upper two floors of the congested floors (for example, standard meeting, cafeteria floor, etc.) is obtained, and the floors between the general floors relative to the total traffic demand between all floors The floor-to-floor traffic demand rate PSR is calculated by Equation 1.

In step SB70, step SB60
The inter-floor traffic demand rate PSR between the general floors calculated in step 1.
It is judged whether it is within 1 (10%). If the inter-floor traffic demand rate PSR of the general floor is within 0.1 (10%), the processes of step SB80 and step SB90 are performed. Further, if the inter-floor traffic demand rate PSR between the general floors is 0.1 (10%) or more, in step SB120, the elevator k1 for direct operation calculated in step SB50 is subtracted from the elevator k units ( k-k1) Plan operation modes for all floor services. Step SB80 sets the divided floors for the divided express operation because the traffic demand between the general floors is small in step SB70. Here, the number of elevators performing the split express operation is determined in step S.
This is the number of vehicles, minus one elevator k that operates in the direct direction, calculated in B50. If (k-k1) is an odd number,
For example, if the number of elevators is 5 and the congested floor is the lowest floor, the low-rise side has 2 elevators and the service demand is about 45% of the total, the high-rise side has 3 elevators, and the service demand is the whole. The divided floors are set so that the congested floors serve both the lower and upper floors. When (k-k1) is an even number, three elevators are used for both the lower and upper floors, and a split floor is set when the traffic demand from the upper floors on the higher floors is about 45% of the total.

In step SB90, step SB80
In the divided floor set in step 3, the inter-floor traffic demand forecast work table PTW created in step SA30 of FIG.
Based on (f, f), the general floor inter-floor traffic demand rate PSR between the high and low floors is calculated by Equation 1, and the general inter-floor traffic demand rate PSR is less than 0.05 (5%). In this case, since there is little traffic demand between the general floors of the high and low floors that have been split, a mode for split express operation without connecting floors is planned. Moreover, the traffic demand ratio PSR between general floors is 0.0
If it is 5 (5%) or more, there is a large demand for traffic between the divided high and low-rise general floors, so we will formulate an operation mode for split express operation with transfer floors. By the above processing, the operation mode according to the traffic demand is planned from the predicted inter-floor traffic demand.
