Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation control device, and more particularly to an operation control device which controls the operation of a plurality of elevator cars and allocates an appropriate elevator car to a hall call. ..

[0002]

2. Description of the Related Art With the widespread use of high-rise buildings in recent years, elevators have been dramatically increased in speed in order to ensure serviceability to passengers. However, the speeding up of this elevator causes an increase in noise (hereinafter, simply referred to as "room noise") reaching a room close to the elevator in the building. Especially, the room is used even at night such as in a hotel or an apartment. In such a case, since there is little noise in the surroundings, the user feels a little noise in the room, and there is a demand for further noise reduction.

By the way, as a noise source of the elevator,
Equipment installed in the machine room, such as hoisting machines and control panels, and equipment that moves up and down in the hoistway, such as elevator cars and counterweights, can be broadly classified into two types. Vibration from these noise sources It is said that the so-called fixed propagating sound, which is caused by vibrating the ceiling or wall of the living room through the beams and pillars and diffusing into the living room, causes the noise in the living room. The fixed propagating sound from the equipment in the machine room only affects the noise of the room on the floor of the machine room or the floor directly below it, so it is relatively easy to take measures, but it is relatively easy to take measures in the elevator car or in the hoistway. The running noise generated by the counterweight affects the noise in the living room on most floors, and therefore it is difficult to take countermeasures against it, and various countermeasures have been conventionally proposed.

[0004] First, as structural measures against running noise of an elevator car or the like, for example, fixing bolts of rail brackets and improving surface roughness of rails have been proposed. However, it was not possible to suppress the noise in the room to the allowable level of NC25 only by taking these structural measures, and the feasibility thereof was low.

Further, as a measure for the running sound of the traveling noise of the elevator car or the like, the traveling speed of the elevator car, which is usually determined in accordance with the traveling distance to the destination floor, is intentionally limited to a low speed to reduce noise in the living room. Is considered to be reduced. Further, although slightly different from the measure against the running noise, as a measure against the wind noise generated by the traveling of the elevator car, for example, an operation management device described in Japanese Utility Model Laid-Open No. 2-129371 is proposed. This operation management device prevents parallel running by shifting the timing of the start of running when it is expected that multiple elevator cars will run in parallel, and as a result,
It is designed to suppress an increase in wind noise in the hoistway due to parallel running.

[0006]

In the conventional measures against the traveling noise of the elevator car, the traveling speed of the elevator car is intentionally limited to the low speed as described above. Therefore, there is a possibility that a problem may occur in terms of serviceability to passengers.

The elevator operation management device described in the publication aims at suppressing wind noise in the hoistway, but originally, the suppression of wind noise has the effect of reducing noise in the elevator car. However, the effect of reducing noise in the room is not so high. Therefore, the noise in the room is still high, and the comfort of the room may be impaired.

[0008] Therefore, the present invention, while ensuring good serviceability for passengers, reduces the noise in the room caused by the traveling of an elevator car or the like, and can maintain the comfort of the room by controlling the operation of the elevator. It is an object to provide a device.

[0009]

According to a first aspect of the present invention, there is provided an elevator operation management apparatus, wherein when a hall call is made on any floor, a plurality of elevators reach the living room by traveling of the elevator cars. Noise predicting means for respectively predicting noise values, assigning means for assigning the elevator car with the smallest noise value predicted by the noise predicting means to the hall call, and traveling control means for controlling traveling of the assigned elevator cars. Is provided.

According to a second aspect of the present invention, in the elevator operation management device, for a plurality of elevators, a distance storage means for storing a distance set value corresponding to the distance to the living room, and a hall call at any floor. When the distance setting value corresponding to each elevator is compared, an allocation means for allocating the elevator car most distant from the living room to the hall call and a travel control means for controlling the travel of the allocated elevator car are provided. It is a thing.

In the elevator operation management apparatus according to the third aspect of the present invention, when a hall call is made on one of the floors, a speed set value corresponding to the traveling speed of the elevator car is predicted for each of the plurality of elevators. Comparing the speed setting value predicted by the speed predicting means, and assigning means for assigning the elevator car having the lowest traveling speed to the hall call, and traveling for controlling the travel of the assigned elevator car. And a control means.

[0012]

According to the first aspect of the invention, when a hall call is made on any floor, the noise predicting means predicts the noise value to the living room due to the traveling of each elevator car. A small elevator car is assigned to the hall call by the allocating means and responds to the hall call by the traveling control of the traveling control means. In this way, the elevator car with the smallest noise value affecting the living room is assigned, and thus the elevator car Room noise due to traveling is reduced, and since the traveling speed of the elevator car is not intentionally limited, there is no fear that the waiting time for passengers will be extended.

According to the second aspect of the present invention, when a hall call is made on any floor, the elevator car farthest from the living room is determined based on the distance set value of each elevator stored in advance in the distance storage means. It is assigned to the hall call by the allocating means, and responds to the hall call by the traveling control of the traveling control means.In this way, the elevator car farthest from the living room is assigned, so that the noise in the room caused by the traveling of the elevator car is reduced. Moreover, since the traveling speed of the elevator car is not intentionally limited, there is no fear that the waiting time for passengers will be extended.

According to the third aspect of the present invention, when a hall call is made on any floor, the speed setting value of each elevator is predicted by the speed predicting means, and the traveling speed is based on the speed setting value. The lowest elevator car is assigned to the landing call by the allocating means, and the traveling control of the traveling control means responds to the landing call. In this way, the elevator car with the lowest traveling speed is allocated. The noise in the room caused by the noise is reduced, and moreover, since the traveling speed of the elevator car is not intentionally limited, there is no fear that the waiting time of passengers will be extended.

Although not shown, hall units similar to the hall unit 7 are installed on floors other than the 66th floor.

FIG. 2 is a schematic view of the 66th floor of a building in which an elevator operation control device according to an embodiment of the present invention is installed, and FIGS. 3 and 4 show an elevator operation control device according to an embodiment of the present invention. It is explanatory drawing which shows the operation state of each elevator managed, and a floor.

In FIG. 2, reference numeral 81 is an elevator hall where the elevators E1 to E3 of the above-mentioned Nos. 1 to 3 are installed, and 82 is a living room provided near the elevator hall 81 with a corridor 83 interposed between them. Elevators E1 to E3
Are installed side by side in the order of the third elevator E3, the second elevator E2, and the first elevator E1 from the side of the room 82. Although FIG. 2 shows the 66th floor of the building, the 61st to 67th floors are all the same as the 66th floor. Then, as shown in FIGS. 3 and 4, the elevator cars 31 to 33 of the first to third units pass through the second floor to the 60th floor set as the express zone, and the first floor, the 61st floor to the 67th floor.
The operation management device 1 of the present embodiment is installed on the floor only on the floor.
By driving the elevator cars 31 to 33, these 61
The operating states of the elevators E1 to E3 are managed in order to reduce the noise to the living room 82 on the first to 67th floors.

In FIG. 3, the elevator cars 31 and 33 of Units 1 and 3 are located on the first floor, the elevator car 32 of Unit 2 is located on the 64th floor, and the elevator cars 32 of Unit 2 are located on the first floor. The car call (shown by 1C2) is registered, and the triangular marks attached to the elevator cars 31 to 33 indicate the service directions. Also, FIG.
Shows that all elevator cars 31 to 33 of Units 1 to 3 are located on the first floor, and a car call (indicated by 64C2) on the 64th floor is registered in the elevator car 32 of Unit 2. The triangular mark attached to each elevator car 31 to 33 indicates the service direction.

Next, the operation of the elevator operation management apparatus of the present embodiment configured as described above will be described. FIG. 5 is a CP of the operation management device for the elevator according to the embodiment of the present invention.
FIG. 6 and FIG. 7 are flow charts showing the operation management routine for the downward call to the 66th floor executed by U.
It is a flow chart which shows a noise value calculation routine for a downstairs call.

The CPU 11 is a main routine (not shown), and from the traveling control devices 21 to 23 of the first to third units via the communication control interface 14, the elevators E to E respectively.
The operation information of 1 to E3 (for example, car position, running or stopping, running direction, car calling position, etc.) and operation information of the landing button 70 of the landing unit 7 are read and stored in the RAM 13, and based on those information. If it is determined that the downward call button 70D on the 66th floor has been operated, the routine of FIG. 5 is executed. In addition to the routine of FIG. 5, the ROM 12 stores programs corresponding to the landing buttons on each floor, and the CPU 11 executes a program corresponding to the operation status of the landing buttons. In the example, a case where the downward call button 70D on the 66th floor is operated will be described as an example.

Now, when the downward call button 70D on the 66th floor is operated, the elevators E1 to E of the first to third units are operated.
Assuming that 3 is in the operation state shown in FIG. 3, as shown in FIG. 5, the CPU 11 determines in step S101 whether or not the elevator cars 31 to 33 have been assigned to the downward call on the 66th floor. .. If the allocation is not yet completed, the elevator E1 ...
The noise value when the counter N indicating the number of the E3 machine is set to "1" corresponding to the first machine and the elevator car 31 of the first machine is assigned to the downward call on the 66th floor as described below. S, the service value W, and the comprehensive evaluation value T are calculated.

Here, the noise value S means that, when a particular elevator car 31-33 is selected, the traveling of the elevator car 31-33 reaches the living room 82 on any of the 61st to 67th floors. It is the expected room noise value,
The smaller this value, the lower the noise in the room. Also,
The service value W is the degree of service expected to be received by passengers when a specific elevator car 31 to 33 is selected. In the present embodiment, this service value W is the same as in a general operation management device. Is the passenger waiting time, in other words,
It is expressed as the time required for the elevator cars 31 to 33 to land on the destination floor, and the smaller this value, the better the serviceability. Further, the comprehensive evaluation value T is the elevator car 3 in consideration of the noise value S and the service value W.
It is a selection criterion of 1 to 33 and is generally a function (normally a linear sum) of the distance setting value S and the speed setting value W. In the present embodiment, it is simply a sum of the noise value S and the service value W. There is. Therefore, the smaller the overall evaluation value T, the lower the noise in the room, and the better the serviceability to passengers. As will be described later, the elevator car 3 having the minimum overall evaluation value T is shown.
1-33 are assigned to downward calls on the 66th floor.

First, the CPU 11 executes the calculation process of the noise value S in step S103. When the noise value calculation routine is called, as shown in FIGS. 6 and 7, the CPU 11
Since the counter N is "1" in step S201, the distance set value S1 is stored in the ROM 12 in advance in step S202 in association with the elevator E1 of the first vehicle.
And In other words, since the elevator E1 of Unit 1 is most distant from the living room, the noise in the living room caused by the traveling of the elevator car 31 is low, and it is advantageous in terms of the distance noise between the living room and the elevator car 31. The value S1 is set to 0, which is the minimum value, and as a result, the total evaluation value T is reduced together with the noise value S, so that the elevator car 31 of the first car is easily assigned.

Next, in step S203, it is determined whether or not the elevator car 31 of the first car is in the downward service, and as shown in FIG. 3, since it is in the upward service, the process proceeds to step S204 and the elevator is moved. Basket 31
Determines whether or not is stopped on the 61st floor or above. Since the elevator car 31 is located on the first floor, step S2
In 05, it is determined whether or not there is a car call on the 61st floor or higher.
It is determined whether or not there is an assigned call above the floor. Since this allocation call has not been made, the ROM is previously stored in step S207.
Of 0 and 20 stored in 12, the larger value 20 is set as the speed setting value S2, and in step S208 the speed setting value S2 is added to the distance setting value S1 to calculate the noise value S. Exit the routine. Therefore, the noise value S is

S = 0 + 20 = 20.

In other words, the elevator car 31 of the first car is 1
Since it is located on the first floor, in order to answer a downward call on the 66th floor, drive at high speed in the express zone from the 2nd floor to the 60th floor and pass the 61st and 62nd floors without slowing down sufficiently. Therefore, the room noise on those floors becomes high, which is disadvantageous in terms of speed noise of the elevator car 31. In addition, the elevator car 31 of Unit 1 at this time does not plan to travel to the 61st floor or higher in response to a car call or an assigned call, so if the elevator car 31 of Unit 1 is assigned, it will be near the 61st and 62nd floors. Will increase the noise in the room. Therefore, the speed setting value S2 is set to a large value of 20, and as a result, the total evaluation value T is increased together with the noise value S, making it difficult to allocate the elevator car 31 of the first car.

In step S204, when the elevator car 31 of the first car is located on the 61st floor or higher,
Since the traveling distance to the 6th floor is short, the arrival speed during traveling is not so high, and the noise in the living room on the 61st to 67th floors is reduced, which is considered to be advantageous in terms of speed noise of the elevator car 31. , Step S205 and step S2
At 06, when the elevator car 31 of the first car is scheduled to travel on the 61st floor or higher in response to the car call or the assigned call, the travel of the elevator car 31 at that time is used to 66
If it responds to a downward call of the floor, it can be said that the noise in the room can be increased and the cause can be eliminated. In these cases, the process proceeds to step S209 and the speed setting value S2 is set to a small value 0.

Then, returning to the routine of FIG. 5, the calculation process of the service value W when the elevator car 31 of the first car is assigned is executed in step S104. In the present embodiment, the calculation process is performed on the assumption that it takes 1 sec to travel one floor and 10 sec to stop once. Therefore, in this case, the call is not registered on the other floors, and the elevator car 31 goes straight to the 66th floor without stopping halfway. Therefore, the service value W is W = 1 sec × (66-1) = 65. Becomes

After that, in step S105, the total evaluation value T when the elevator car 31 of the first car is assigned to the downward call on the 66th floor (hereinafter, T1 is associated with the car number and the same applies to the second car and the third car). To T2 and T3). As described above, this comprehensive evaluation value T1
Is the sum of the noise value S and the service value W, so T1 = 20 + 65 = 85.

Next, in step S106, the counter N is incremented by "+1", and in step S107, the counter N is still 2. Therefore, the process returns to step S103, and the elevator car 32 of the second car 32 responds to the downward call on the 66th floor. The noise value S when is assigned is calculated.

Therefore, since the counter N is "2" in step S201 of FIGS. 6 and 7, the CPU 11 sets the distance set value S1 in advance in step S210 in correspondence with the elevator E2 of the second car. And In other words, the elevator E2 of Unit 2 is the three elevators E1
At the intermediate position of E3 to E3, the noise set in the room 82 by the traveling of the elevator car 32 is also intermediate, so that the distance set value S1 is set to 5 which is an intermediate value between 0 and 10.

Next, in step S203, since the elevator car 32 of the second car is in the downward service, the process proceeds to step S211, and the elevator car 32 is located on the 67th floor, that is, the upper floor of the 66th floor called downward. It is determined whether or not the elevator car 32 is located on the 64th floor, and therefore the current car position is 64 at step S212.
Determine if there is an assigned call above the floor. Since there is no assigned call, it is determined in step S213 whether or not there is an upward assigned call on the 61st floor or higher. Since there is also no upward assigned call, it is determined in step S214 whether or not there is a car call on the first floor. As shown in FIG. 3, since the car is called on the first floor, the process proceeds to step S207 and the speed setting value S
2 is set to 20, the noise value S is calculated in step S208, and this routine ends. Therefore, the noise value S
Becomes S = 5 + 20 = 25.

In other words, the elevator car 32 of the second car is 6
Since it is located on the 4th floor, it cannot respond to a downward call on the 66th floor using the opportunity for downward service (a car call on the 1st floor) as in the case on the 67th floor. Therefore, the elevator car 32 will respond to the downward call on the 66th floor after the downward service, passing through the vicinity of the 61st floor and the 62nd floor at high speed, and increasing the noise of the rooms on those floors.
It is disadvantageous in terms of speed noise of the elevator car 32.
In addition, since the elevator car 32 of the second car at the present time does not plan to travel to the 61st floor or higher in response to the allocation call or the upward allocation call, if the elevator car 32 of the second car is allocated, the elevator car 32 of either floor It will create the cause of increasing noise in the room. Therefore, the speed setting value S2 is set to a large value of 20, and as a result, the total evaluation value T is increased together with the noise value S, making it difficult to allocate the elevator car 32 of the second car.

When the elevator 32 of the No. 2 vehicle is located on the 67th floor in step S211, it is possible to respond to a downward call on the 66th floor by using the opportunity for downward service, so the arrival speed during traveling is not so high. , The 61st to 67th floors are reduced in room noise, which is considered to be advantageous in terms of speed noise of the elevator car 32. Also, in step S212 and step S213, response to the allocation call or the upper allocation call is made. Then, when the elevator car 32 of the second car is scheduled to travel on the 61st floor or higher, by using the traveling of the elevator car 32 at that time and responding to the downward call on the 66th floor, the cause of increasing the noise in the room can be eliminated. In these cases, the process proceeds to step S209 and the speed setting value S
Set 2 to a small value of 0.

If there is no car call on the first floor in step S214, it is determined in step S215 whether there is an upper allocation call. If there is no upper allocation call, the car position is determined in step S216. It is determined whether or not there is a downward allocation call below, and when there is no downward allocation call, it is not necessary to drive the elevator car 32 of Unit 2 to the first floor, which is advantageous in terms of speed noise. The speed setting value S2 is set to 0 in step S209.

After that, in step S104 of FIG. 5, the service value W is calculated when the elevator car 32 of the second car is assigned, and the elevator car 32 responds to the car call from the 64th floor to the 1st floor. 6 after stopping on the floor
Since the vehicle travels to the 6th floor, the service value W is W = 1 sec × {(64-1) + (66-1)} + 10 = 138.

After that, when the total evaluation value T2 of the elevator car 32 of the second car is calculated in step S105, T2 = 25 + 138 = 163.

Next, in step S106, the counter N is incremented by "+1", and since the counter N is still 3 in step S107, the process returns to step S103, and the elevator car 33 of the third car for the downward call on the 66th floor is returned. The noise value S when is assigned is calculated.

Therefore, since the counter N is "3" in step S201 of FIGS. 6 and 7, the CPU 11 sets the distance set value S1 in step S217 in advance corresponding to the elevator E3 of the third car. And That is, since the elevator E3 of Unit 3 is closest to the living room 82, the running room noise due to the traveling of the elevator car 33 is high, and it is disadvantageous in terms of noise in distance between the living room 82 and the elevator car 31, The distance setting value S1 is set to the maximum value of 10, and as a result, the total evaluation value T is increased together with the noise value S, making it difficult to allocate the elevator car 33 of the third car.

Since the elevator car 33 of the third car is in the upper service at step S203, the subsequent processing proceeds to step S204, step S205, and step S206, just like the elevator E1 of the first car. The speed setting value S2 is set to 20 in S207, and the noise value S is set to S = 10 + 20 = 30 in step S208.

Further, as in the case of allocating the elevator car 33 of the third car in step S104 of FIG. 5, the same 65 as that of the elevator car 31 of the first car is calculated, and in step S105, the elevator car 33 of the third car is calculated. The total evaluation value T3 of the above is set as T3 = 30 + 65 = 95.

Next, in step S106, the counter N is incremented by "+1", and since the counter N is 4 in step S107, the process proceeds to step S108, and the elevators E1 to E1 having the smallest total evaluation values T1 to T3 are obtained.
Select 3. As described above, T1 = 85, T2 = 1
Since 63 and T3 = 95, the elevator E1 of the first car is selected in this case, and the CPU 11 determines in step S109.
Then, a registration signal is output to the hall unit 7 on the 66th floor via the communication control interface 14 to light the downward call button 70D to indicate that the hall call has been registered to the passengers, and the traveling control device 21 of the first unit. The allocation signal is output to and the routine ends. Then, in response to the allocation signal from the CPU 11, the traveling control device 21 is set on the 1st floor of the 66th floor.
Turn on the down home lantern 70D of Unit No. 66, and
The allocation of the elevator car 31 of the first car is displayed to the passengers on the floor, and at the same time, the elevator car 31 of the first car is driven to the 66th floor in response to the downward call.

As described above, the operation management device 1 of this embodiment
Then, the distance set value S1 that predicts the distance noise between the living room 82 and the elevator car 31, and the elevator cars 31 to 31.
The noise value S is calculated based on the speed set value S2 that predicts the traveling speed of 33, and the service value W indicating the waiting time of the passenger is added to the noise value S to calculate the total evaluation value T. Select the elevators E1 to E3 with the smallest evaluation value T,
It is responding to a downward call on the 66th floor. Then, as described above, when the downward call is made on the 66th floor in the operation state of FIG. 3, the elevator E2 of the second unit is excluded because it is not suitable for allocation because the service value W is very large, and the remaining first unit is left. Comparing the elevator E1 of No. 3 and the elevator E3 of Unit 3, the service value W and the speed setting value S2
However, since the elevator E1 of the first car is further away from the living room 82 and the distance setting value S1 is smaller by 10, the room noise is selected to be lower.

That is, the elevator E1 of the first car was selected in consideration of the noise in the room and the serviceability to passengers, and as a result, the elevator car 31 was driven by the elevator E1.
The room noise that extends to the room 82 on the first to 67th floors is reduced, and the waiting time for passengers on the 66th floor is shortened. Moreover, unlike the measures described in the related art, the traveling speed of the elevator car 31 is not intentionally reduced, so that there is no possibility that the waiting time of the passenger will be extended.

Assuming that the elevator E3 of the third car can respond to the call on the 66th floor 11 seconds earlier, the service value W becomes 11 smaller. Therefore, in this case, even if the noise in the room is sacrificed to some extent, the elevator E3 of Unit 3 which has good serviceability to passengers on the 66th floor will be selected.

On the other hand, when the downward call button 70D on the 66th floor is operated, the elevators E1 ...
The case where E3 is in the operation state shown in FIG. 4 will be described. In this case, since the noise value S, the service value W, and the comprehensive evaluation value T of the elevator E1 of the first unit and the elevator E3 of the third unit are the same as those in the operation state shown in FIG. Only the elevator E2 of Unit No. will be described.

The CPU 11 increments the counter N by "+1" to 2 in step S106 of FIG. 5, shifts to step S103 through step S107, and allocates the elevator car 32 of the second car to the downward call on the 66th floor. The noise value S in the case of Therefore, since the counter N is "2" in step S201 of FIGS. 6 and 7, the distance set value S1 is set to 5 corresponding to the elevator E2 of the second car in step S210, and step S203 is performed.
Since the elevator car 32 of the second car is being serviced upwards, the process proceeds to step S204. Further, step S
At 204, the elevator car 32 is not stopped on the 61st floor and above, but is located on the 1st floor.
It is judged whether there is a car call on the 61st floor or above in 6
Since the car is called on the 4th floor, if the traveling of the elevator car 32 at that time is used to respond to the downward call on the 66th floor, it is considered that the noise in the room can be increased and the cause can be eliminated, and the speed set value S2 is set in step S209. Is set to a small value of 0.

Then, in step S208, the noise value S is set to S = 5 + 0 = 5.

Further, in step S104 of FIG. 5, the service value W is calculated when the second elevator car 32 is assigned, and the elevator car 32 is moved from the first floor to 64th floor.
66 after responding to the car call on the first floor and temporarily stopping on the 64th floor
Since the vehicle travels to the floor, the service value W is W = 1 sec × (66-1) + 10 = 75.

After that, in step S105, the total evaluation value T2 of the elevator car 32 of the second car is set to T2 = 5 + 75 = 80, and the elevator E1 having the minimum total evaluation values T1 to T3 in step S108 after steps S106 and S107. Select ~ E3. As mentioned above, T1 = 8
5, T2 = 75, T3 = 95, so in this case 2
The elevator E2 of the car No. is selected, and the CPU 11 outputs the registration signal to the hall unit 7 on the 66th floor and the allocation signal to the traveling controller 22 of the car No. 2 in step S109, and this routine ends. As a result, 66
The elevator car 32 of the second car will respond to the downward call of the floor.

As described above, in the operation state of FIG.
When a downward call is made on the 6th floor, the elevator E2 of Unit 2 has a larger service value than the other elevators E1 and E3, but it uses the opportunity to call the car on the 64th floor to make a downward call on the 66th floor. Since it is possible to respond and the speed setting value S2 is set to 0, the room noise is selected to be low.

That is, the elevator E2 of Unit 2 was selected in consideration of the noise in the room and the serviceability to passengers, and as a result, the elevator car 32 was driven by the elevator E2.
The room noise that extends to the room 82 on the first to 67th floors is reduced, and the waiting time for passengers on the 66th floor is shortened. Moreover, unlike the measures described in the related art, the traveling speed of the elevator car 32 is not intentionally reduced, so that there is no possibility that the waiting time of the passenger will be extended.

When the elevator car 32 of the No. 2 machine goes straight to the 64th floor, the noise in the room near the 61st and 62nd floors increases, but this point is that the elevator car 32 of the No. 2 machine is at the 66th floor. The same result is obtained even if the call is not answered to the downward call of the elevator car. As described above, it cannot be prevented only by managing the allocation of the elevator cars 31 to 33 based on the routines of FIGS. To do.

As described above, the operation management apparatus for the elevators according to the above-described embodiment includes the elevators E1 to E1 of the first to third units.
The ROM 12 that stores the distance setting value S1 that is set according to the distance between E3 and the living room 82 and the speed setting value S2 that is set according to the traveling speed of the elevator cars 31 to 33, and the ROM 12 from each floor. When the hall call information is entered and a hall call is made on any of the floors, the corresponding distance set value S1 is selected for each elevator E1 to E3 and according to the traveling speed of the elevator cars 31 to 33. The speed setting value S2 is predicted and the distance setting value S
The speed setting value S2 is added to 1 to calculate the noise value S, and the service value W indicating the time required to land on the destination floor is added to calculate the comprehensive evaluation value T, and the total value of each elevator E1 to E3 is calculated. The CPU 1 that compares the evaluation values T and assigns the elevator cars 31 to 33 having the minimum total evaluation value T to the hall call.
1 and the traveling control devices 21 to 23 of Nos. 1 to 3 for controlling the traveling of the elevator cars 31 to 33 assigned by the CPU 11 to respond to the hall call.

Therefore, when a hall call is made on any of the floors, for each elevator E1 to E3,
Distance set value S1 according to the distance to the living room 82 and speed set value S2 according to the traveling speed of the elevator cars 31 to 33.
A noise value S is calculated based on the noise level S, and the elevator cars 31 to 33 having a minimum total evaluation value T obtained by adding the service value W to the noise value S are assigned to the hall call, and as a result, the elevator cars 31 to 33 are assigned. It is possible to reliably reduce the noise of the living room that reaches the living room 82 on each floor by traveling and to ensure the comfort of the living room 82.

Further, when allocating the elevator cars 31 to 33, not only the noise in the room but also the serviceability to passengers are taken into consideration, and moreover, the elevator cars 31 to 33 are aimed at reducing the noise in the room as in the conventional example. Since the traveling speed of the vehicle is not intentionally limited, it is possible to prevent the waiting time of the passenger from being unduly extended and always provide a good service.

By the way, in the above embodiment, the service value W is added to the noise value S to calculate the total evaluation value T, and the allocation of the elevator cars 31 to 33 is determined based on the relative evaluation value T. The present invention is not limited to this as long as it is possible to select the elevator cars 31 to 33 that produce low noise in the living room 82. Therefore, for example, without considering the service value W, it is possible to allocate the elevator cars 31 to 33 having the smallest noise value S. Also, the total evaluation value T
It is also possible to give importance to one of the noise in the room and the serviceability to passengers by multiplying any value by a coefficient, instead of simply adding the noise value S to the service value W. It is also possible to select the elevator cars 31 to 33 by multiplying by 0.5 and placing particular importance on room noise.
Further, the distance set value S1 indicating the distance noise to the living room 82
And the noise value S based on only one of the speed setting value S2 indicating the speed noise of the elevator cars 31 to 33.
It is also possible to calculate Further, not only the noise value S and the service value W are taken into consideration, but, for example, when two of the elevator cars 31 to 33 travel in the same direction, the noise in the room increases, so that such an operating state is set. The operation is controlled so as to avoid it, or one of the elevator cars 31 to 33 has a maximum maximum number of passengers and is occupied by a room 82.
When it is expected that the noise exerted on the vehicle will be high, the elevator cars 31 to 33 can be controlled so as to be hard to be assigned.

In the above embodiment, the elevator car 3
Focusing on the noise reaching the living room 82 by running 1 to 33,
Although the elevator cars 31 to 33 that have low noise are selected, in actuality, as in the case of the elevator cars 31 to 33, noise is exerted on the living room 82 even when the counter weights 51 to 53 travel, so that the counter weights 51 to 53 are used. Taking into account noise in the room, elevator cars 31 to 3
It is also possible to make an allocation of 3.

Further, in the above embodiment, the second to 60th floors are set as the express zones, and the elevator cars 31 to 33 are set.
The operation control in the case of landing only on the first floor, 61st floor to 67th floor has been described.
The present invention is not limited to this, and can be applied to operation control in various cases such as when the express zone is not set.

On the other hand, in the above embodiment, the operation control for the purpose of reducing the noise in the living room is always executed as in the routines shown in FIGS. 5 to 7 without distinction between daytime and nighttime.
When it is not necessary to reduce noise, it is of course necessary to execute operation control considering only normal serviceability. Therefore, for example, to perform normal operation control in the daytime and execute operation control for the purpose of reducing noise in the room at night,
The control content may be automatically switched according to the time zone, or may be manually switched by a changeover switch.
