Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation management device, and more particularly to a service division operation system in an elevator group management control device.

[0002]

2. Description of the Related Art Conventionally, in a group management control device for elevators, usually, when a hall call occurs, each elevator is evaluated by an assignment evaluation formula, and the service elevator is determined by the evaluation value. When the traffic volume is large and the transportation capacity needs to be strengthened, the service floor is generally divided into two or three and each elevator is serviced by its own elevator.
As a result, the number of stoppages is reduced, so that one round time of each elevator is shortened, and the transport capacity per unit time can be improved.

However, in such a fixed service division, it is necessary to determine the division floor in advance from the staff members on each floor and to specify the start time and the end time, which is not only troublesome. However, the actual traffic demand fluctuates slightly, so it is not possible to cope with it. Therefore,
As an improvement plan for these, for example, JP-A-60-1
Japanese Patent No. 22674 proposes that the demand distribution for the floor that is the center of the service is obtained during peak operation, and the zone division floor of the zone division operation is set and updated based on this demand distribution information. Also, JP-A-63-
In 196478, there is proposed that if the elevator in one of the service zones breaks down and becomes a non-service floor after the division, the service floor of the elevator in the other service zone is changed to enable service.
Further, Japanese Patent Laid-Open No. 155542/1993 proposes a destination button and a destination indicator at the landing so that the range of service floors can be expanded by the fuzzy theory.

[0004]

The respective prior arts proposed as these improvement measures are considered as an extension of fixed service division, and are improved when an imbalance occurs in each service zone. Or, it becomes possible to enable service when an elevator that services a certain service zone fails and becomes unavailable.

However, these conventional techniques are techniques for improving the transportation capacity when going to work, and cannot be applied as they are to other time zones and traffic demands. In addition, basically, the traffic demand in a specific time zone is investigated and prepared in advance, so whether or not the demand was met by actually carrying out a division express, and the imbalance in the demand caused the transportation capacity on a specific floor. It does not take into consideration such factors as shortages, long waits and leftovers. Japanese Patent Laid-Open No. 5-
In the technology described in Japanese Patent No. 155542, the imbalance of each zone can be improved by fuzzy inference.
Only the floors that are the boundaries of the zone are changed, so there was a large amount of traffic demand continuously on the higher floors of the high-rise zone, and various traffic demands could not be dealt with, such as when other traffic demands could not be balanced. .

An object of the present invention is to provide an elevator operation management device capable of improving the transportation capacity not only when commuting to work but also for various traffic demands.

[0007]

In order to solve the above problems, according to the present invention, the traffic demand dividing means divides the divided traffic demands so that the traffic volume per service elevator becomes equal. More specifically, a simulation means for simulating the operation of the elevator is provided, and the matters decided by the traffic demand dividing means and the service elevator deciding means are simulated, and the decided matters are corrected based on the result. If the number of express elevators determined by the service elevator determining means is not an integer, the same elevator is switched to the express elevator and the general service elevator by time division, and the average service number within a certain period is almost the same as the express elevator number. Express service that equalizes and further divides by means of traffic demand division The floor of over emissions not only continuous floor as in the prior art, is characterized in that as may comprise a discontinuous floor.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the overall structure of the present invention. The information on the hall call buttons 101 to 10n is
It is sent to the hall call collection unit 21 in the group management control device 2. Information of the cars 31 to 3n is the machine control devices 41 to 4
car information collection unit 2 in the group management control device 2 via n
Sent to 2. If the current time zone and the traffic demand are normal traffic demands based on the determination result of the determination unit 24, the allocation control unit 23 generates based on the information of the hall call collection unit 21 and the car information collection unit 22. The car to be serviced for the hall call is determined, and a signal is sent to the machine control devices 41 to 4n to service the hall call.

The learning unit 25 learns the information of the hall call collecting unit 21 and the car information collecting unit 22, and the clock unit 26.
The traffic demand for each floor is collected for each time zone and type of traffic demand using the time of. The learned traffic demand is sent to the service dividing unit 27 as a traffic demand for each time zone and for each type of traffic demand, and the service dividing unit 27 determines whether or not the traffic demand is a predetermined value or more, and a predetermined value. If it is above, the service floor of an elevator will be divided into a predetermined number of zones. Zone traffic calculation unit 27 in service division unit 27
1 is 1 for each zone divided by the service division unit 27
The traffic volume per vehicle is calculated, and the adjusting unit 272 calculates the service floors and the number of service elevators in each zone by the zone traffic volume calculating unit 271 so that the traffic volume per vehicle becomes equal. Adjust to. The service division unit 27 records the service floors and the number of service elevators in each zone after the adjustment unit 272 has adjusted, on the division floor table 28 for each time zone and for each type of traffic demand. Based on the information of the hall call collection unit 21, the car information collection unit 22, and the time of the clock unit 26, the determination unit 24 executes the service division in which the current traffic demand is described in the divided floor table 28. , Determine if it is a traffic demand.
If the time zone for service division and traffic demand, the division type of the service floor to be currently used and the number of service elevators in each service zone are sent to the allocation control unit 23,
The allocation control unit 23 determines which zone the generated hall call belongs to based on the division type and the number of services of each service elevator, and determines the elevator to be serviced.

FIG. 2 is a flow chart when allocating a service elevator to a hall call. When an elevator hall call occurs, it is determined whether the current traffic demand is a traffic demand for service division operation (step 20).
1). If the traffic demand is not a traffic demand for service division operation, normal allocation is performed (step 202). If it is a traffic demand for service division operation, it is determined whether the generated hall call belongs to the floor for express service. The determination is made (step 203). If the floor is for an express service, the elevator for the express service is assigned (step 204). If the floor is not for the express service, the service elevator is assigned from the elevators that are normally serviced (step 205). ).

FIG. 3 is a flowchart for determining the service floor of the service division operation. First, the traffic demand is learned for each time zone (step 301). Next, it is determined whether the learned traffic demand requires service division operation (step 302). If it is not necessary, the processing is terminated, and if necessary, the traffic demand from each floor to each floor is obtained (step 303). Next, the number of people to be carried per vehicle is calculated from the total number of people getting on and off (step 304). Next, the traffic demand for the express service is selected from the ones with the most traffic demands from each floor to each floor (step 305), and this is repeated until the selected traffic demand exceeds the number of persons to be transported per unit (step). 306), when exceeded, send the result to the split floor table (step 3)
07).

FIG. 4 is an explanatory diagram of the operation of the present invention. In this figure, the bars on the left side are for riding, the bars on the right side are for descending, the hatched bars are for up, and the unhatched bars are for down traffic. When the traffic demand is uneven as shown in FIG. 4 (a), even if the elevator is stopped on the way floor, it is not possible to get on because it is almost full, and this causes unnecessary stoppage of the elevator. A phenomenon occurs in which one round of the elevator takes a long time and the transportation capacity decreases. In this figure, there is a large amount of traffic demand on the 6th and 7th floors, and the 5th and 4th floors are fully occupied and cannot be used. Therefore, as shown in FIG. 4 (b), the traffic demand is divided into a traffic demand with a large traffic volume from a specific floor and other general traffic demands, and the elevators are serviced by different elevators. Since the service elevator does not service the heavy traffic demand on the congested floor, it will not be full and the general floor service will be possible. The express elevator servicing the congested floor is in the state of piston transportation between the hall call generation floor and the target floor, which is the congested floor, and the number of stops is reduced, so the lap time is shortened,
Improvement of transportation capacity can be expected. As a result, compared to the case where the express service operation by service division is not performed as shown in FIG.
It becomes possible to increase the transportation capacity.

FIG. 5 is an explanatory diagram of the service floor division system of the present invention. Based on the traffic demand data learned by the learning unit 25, the traffic demand from each floor to each floor is created as a traffic demand table for each floor as shown in FIG. Separately, calculate the amount of traffic that should be carried per vehicle. As shown in FIG. 5 (b), the one with a large traffic volume is selected from the traffic demand on each floor until the traffic volume per vehicle is reached, and this is used as the service floor of the express elevator. In this example, there is a large amount of traffic from the 6th and 7th floors to the 1st floor, and when this is summed up, the traffic floor per vehicle is reached, so the service floors of the express elevator are determined to be the 1st, 6th, and 7th floors. In this example, since there is a large amount of traffic from the 6th and 7th floors to the 1st floor, the service floor of the express elevator is 1,
Although it has been decided on the 6th and 7th floors, that is, on consecutive floors
If there is a lot of traffic from the 4th and 7th floors to the 1st floor,
If there is a large amount of traffic from the 7th floor or 4, 6, 7th floor to the 1st floor, the service floor of the express elevator including the 1, 4, 6, 7th floor, that is, the discontinuous floor, is determined.

In the above, an example in which one elevator is operated as an express elevator has been described. However, when there is a large amount of traffic demand and there is no single elevator,
A plurality of elevators may be used as an express elevator. According to the present embodiment, it is possible to appropriately determine the sharing of the general service elevator that services the express elevator and the general floor, and the service floor of the express elevator is not limited to the continuous floor as in the conventional case, but the discontinuous floor can also be provided. Since it is allowed, there is an effect that the traffic volume per elevator in each service zone can be equalized and the operation can be efficiently performed.

FIG. 6 is a block diagram showing the overall configuration in the case of verification by a simulator. Service division unit 2
The service zones of the express elevator and general service elevator determined by 7 are sent to the simulator 29.
The simulator 29 uses the learning result of the learning unit 25 to perform an elevator operation simulation, and returns the result to the service dividing unit 27. If the simulation result is close to the result predicted in advance by the zone traffic calculation unit 271, it is sent to the divided floor table 28 as it is, and if there is a problem such as a large difference from the predicted result, the adjustment unit 272 re-divides it. Also, send this to the simulator 29 and repeat this until satisfied.

FIG. 7 is a flow chart for verification by a simulator. Before sending the service floor of each zone and the number of elevators to the divided floor table 28, a simulation is performed by a simulator (step 7
01), and it is verified whether the result is close to the prediction result or whether a failure has occurred (step 702), and if there is a failure, the procedure is the same as that of FIG. 3 except that step 303 is repeated. As a defect, it will be judged whether there is a particularly long wait on any floor, and a large amount of leftovers.

According to the present embodiment, since it is possible to detect a defect caused by performing a service division operation determined in advance by simulation, it is possible to determine a service division method that avoids this.

FIGS. 8 and 9 are flow charts in the case where the value of the number of express elevators to be serviced is allowed even after the decimal point. In the embodiments so far, the express elevator is always an integer, and the traffic demand to be serviced by this express elevator is selected. Performance is reduced. Therefore, FIG.
It is similar to FIG. 3 until the number of persons to be carried per vehicle is calculated (step 304) as shown in FIG. 3, and all the traffic demands that should perform the express service operation are selected (step 80).
1) sum the selected traffic demands (step 802),
The number of elevators required for the express service operation is calculated by dividing the total traffic demand for the express service operation by the number of persons to be carried per unit (step 803). The subsequent steps are the same as in FIG. Here, the number of express elevators is allowed below the decimal point. FIG. 9 is a flowchart when allocating a service elevator, and is the same as FIG. 2 up to the determination of the traffic demand (step 201), and thereafter within a fixed time or within the duration of the traffic demand for performing the express service operation. The number of express elevators is increased / decreased so that the average number of express elevators becomes the number of elevators determined in step 803 of FIG. 8 (step 901). That is,
By time-sharing, the same elevator is switched to an express elevator and a general service elevator so that the average number of services within a certain period becomes the determined number of express elevators. Switch between express elevator and general service elevator after each operation. Other than that, it is the same as FIG. The increase or decrease of the express elevator is performed when the elevator which is changed from the express to the normal or from the normal to the express reaches the end floor, when there is no service call and the car is emptied. In addition, the selection of an elevator whose service floor will be changed is determined by comprehensively considering the position of the elevator in the hall, the condition of the car, and the like.

According to this embodiment, the number of service elevators within a fixed time can be reduced to a decimal point by time division, and more appropriate and detailed service can be performed.

[0021]

As described above, according to the present invention,
Since the traffic demand was divided so that the traffic volume per service elevator for each traffic demand after division was equal,
Appropriate allocation of express elevators and general service elevators can be appropriately determined for various traffic demands not only when going to work,
Transport capacity can be improved. In addition, an operation simulation is performed according to the service zones and the number of elevators of the determined service division, and if the result is a malfunction, the determined above items are corrected, so the determined service division operation should be performed. It is possible to detect a failure due to the above in advance and determine a service division method that avoids this failure. further,
Since the number of service elevators within a fixed time can be reduced to the decimal point by time division, more appropriate and detailed service can be provided. Furthermore,
The service floor of the express elevator is not limited to continuous floors as in the past, but discontinuous floors are also allowed, so the traffic volume per vehicle in each service zone can be more evened out,
The transportation capacity can be further improved.
