Abstract

PURPOSE:To provide an elevator group management control device for equalizing services at each floor, and preventing a drop in operation service for passengers waiting at a hall while maintaining required transportation efficiency, when passengers' destinations are concentrated upon a specific floor. CONSTITUTION:When elevator operation state exceeds a certain level, a concentrated state judgement means checks whether passengers' destinations are concentrated on a specific floor. When it is found that any concentrated state is existing, the floor where a service level for passengers drops, is selected among assigned hall calls. Also, an elevator assigned to the aforesaid floor with a deteriorated service level is caused to respond thereto during a travel in a direction opposite to the specific floor. In this case, when a hall call for a direction opposite to the specific floor is detected and there is a hall call for the opposite direction, a hall indicator is made to display information in mode different from an ordinary case, thereby guiding waiting passengers at the time of opening an elevator door.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control system used when a plurality of elevators are operated between a plurality of floors.

0002

[Prior Art] In recent elevator systems, in order to improve the operating efficiency of multiple elevators installed in parallel and to improve the service to elevator users, the elevators that respond to landing calls on each floor are Computers are used to allocate information rationally and quickly.

That is, when a landing call occurs, the group management control device selects and assigns the most suitable elevator to service the landing call from among a plurality of elevators, and assigns the other elevators to respond to the landing call. I try not to let it happen.

[0004] At the elevator landing, a display lamp (landing lantern) installed near the entrance of the assigned elevator lights up, and just before the elevator arrives, the lamp starts blinking along with the sound of a chime. It looks like this.

In addition, in such an elevator system, with the recent development of microcomputers, car call registration data or boarding/alighting load data when responding to each elevator landing are measured in real time. Traffic flow between floors is being monitored.

[0006] The group management control device predicts the traffic demand after the occurrence of a hall call from the traffic flow thus grasped, and performs the above-mentioned elevator assignment based on this prediction.

FIG. 9 is a schematic diagram showing the structure of such an elevator group management control device. That is, the landing call input/output control units 2a1...2an are connected to the group management control unit 4 via the low-speed transmission line 3 to the call buttons 1a1...1an of the landings on each floor.

[0008] This group management control section 4 includes single control sections 5a1...5 installed in each elevator via the low-speed transmission line 3.
am and a monitoring panel 6 installed in the monitoring room, and also connected to the group management control section 4 and the single control section 5a1...5
am is also connected by a high-speed transmission line 7.

Next, the operation of FIG. 9 will be explained. For example, if a user presses a call button 1an at a landing on the nth floor, the landing call input/output control section 2an sends a call signal to the group management control section 4. When the call signal is input, the group management control unit 4 calculates a predicted non-response time (predicted arrival time plus call elapsed time) by detecting the current position of each elevator, and based on this calculation result. , performs a predetermined evaluation and assigns the most suitable elevator to the landing call on the nth floor.

[0010] For example, if the optimum elevator is the elevator associated with the single control unit 5a1 (assumed to be No. 1), the group management control unit 4 sends an allocation command signal to the single control unit 5a1, and this allocation command signal Based on this, the landing lantern (
(not shown) lights up. The illumination of this platform lantern indicates that users waiting on the nth floor only have to wait in front of the entrance door of elevator No. 1 among the plurality of entrance doors.

By the way, in a building where a cafeteria is installed on a specific floor, the demand for traffic to the specific floor increases extremely during special times such as the first half of the lunch break. Therefore, better transport efficiency is required during such special time slots than during normal time slots.

[0012] Here, the case where good transportation efficiency is achieved means that an elevator bound for a specific floor has to wait until the elevator reaches the specific floor to stop at each floor due to the elevator being full. This refers to cases in which the service on each floor is equalized without passing through the floors directly, and when the passenger arrives at a particular floor, it is at or close to full.

In the conventional elevator group management control device,
As mentioned above, in order to ensure good transportation efficiency, when allocating elevators to landing calls for each floor, in addition to the predicted non-response time described above, the load at the floor where the elevator will stop is also predicted, and the allocation Because the elevator is full, we are doing everything possible to avoid situations where passengers simply pass through the floor they should have stopped at. In other words, allocation control is basically performed so that users are boarded as evenly as possible for each elevator in operation.

[0014] As mentioned above, when a call for a platform for each floor occurs, elevators are allocated in anticipation of the users boarding from these platforms. At peak times when the
If a call occurs on a floor, the predicted load on each floor is 16 people, and the car load is 24 people, then f2
The floor will not be filled with people, and the other units (1 and 2) have a long predicted response time, and if you assign it to a unit other than unit 3, unit 3 will carry 16 people and come to the dining room floor.
Because it is unfavorable in terms of transportation capacity, there are cases where it is assigned to Unit 3 based on relative evaluation.

[0015] Assuming that the number of passengers waiting at the platform on each floor f1 and f2 is 16, which matches the prediction, 16 people can board on the f1 floor, but only 8 can board on the f2 floor. This is an unfavorable situation from the viewpoint of uniformity of services on each floor.

[0016]

[Problem to be Solved by the Invention] Even if the allocation is made in consideration of the load prediction, in the case where there are many passengers waiting at each floor as mentioned above, the number of passengers on the elevator is not limited. In general, floors further away from a particular floor tend to be advantageous, and floors closer to it tend to be disadvantageous. Although equalization can be achieved by limiting the number of passengers as described above, it is practically difficult to do so from the standpoint of user-friendliness.

[0017] For this reason, in order to maintain transportation capacity and equalize the services on each floor when the destination floors of users are concentrated on a specific floor, allocations are made to floors with reduced service. A method has already been filed (Japanese Patent Application No. 2-260482) in which the elevator is operated in a direction opposite to that of a specific floor.

For example, in FIG. 10, if the f1 floor and f2 floor respond at a certain time, the next one
The periodic time means that the f2 floor is treated as a lower service floor and is made to respond during up direction operation, and the f2 floor and then the f1 floor are made to respond in that order. however,
As shown in Figure 11, if Unit 3 has already been assigned a platform call in the direction opposite to the floor with reduced service on the f2 floor, that is, in the up direction, when the f2 floor is operating in the up direction, a specific floor direction call is assigned. , i.e. down
When responding to direction calls, it is impossible to determine which direction passengers are being guided using only the platform lantern.
A phenomenon occurs that confuses passengers at the platform.

[0019] Therefore, the present invention maintains transportation efficiency when the destination floors of users are concentrated on a specific floor, equalizes the service on each floor, and reduces the usability for passengers waiting at the platform. The purpose of the present invention is to provide a group management control device for elevators that does not cause problems.

[0020]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention operates a plurality of elevators between a plurality of floors, and in response to a landing call from each floor by a user, selects one of the plurality of elevators. In the elevator group management control device, the elevator group management control device is configured to assign a user to respond to the user's destination floor based on the operation status detection means for detecting the operation status of the elevator, and the detection result of the operation status detection means. concentration state determination means for determining whether or not the concentration state is concentrated on a specific floor; and when the concentration state determination means determines that the concentration state is concentrated on a specific floor, the level of service to users is reduced. A lower service floor detection means for detecting a floor, and an elevator assigned to the lower service floor detected by the lower service floor detection means to be set to the lower service floor when operating in the opposite direction to the specific floor. an elevator responding means for causing a response, a two-way call detecting means for detecting that there is a landing call in the opposite direction to a specific floor on the floor where the service level has decreased, and an elevator assigned to the floor where the service level has decreased. Elevator notification means for displaying a landing display in a different display format than usual when there is a landing call in a direction opposite to the specific floor, and for notifying the car operating direction or passenger guidance when the car door is opened; It is equipped with the following.

[0021]

[Operation] In the above means, the operation status detection means detects the operation status of each elevator, and based on this detection, when the operation status exceeds a certain level, the concentration status determination means detects the operation status of each elevator. It is determined whether or not the information is concentrated on a specific floor.

[0022] If it is determined that the person is in a concentrated state,
The service degraded floor detection means selects a floor where the service level for the user is degraded among the assigned calls. The elevator response means causes the elevator assigned to the floor with a lower service level to respond to the lower service floor when operating in a direction opposite to the specific floor.

In this case, the bidirectional call detection means detects that there is a landing call in the opposite direction to the specific floor, and when the elevator notification means indicates that there is a landing call in the opposite direction, the landing indicator is set to the normal state. Displayed in different formats to guide passengers waiting at the platform when the car door opens. Therefore, the above objective can be achieved.

[0024]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a block diagram showing the configuration of the main parts of this embodiment. An operating status detecting unit 8 is provided in the group management control unit 4, and this operating status detecting unit 8 is connected to the single control unit 5a via the low-speed transmission path 3 and the high-speed transmission path
The operating status of each elevator, such as the contents of call registration in each elevator car, is detected from the single control circuits 5b1 to 5bm within 1 to 5am.

The detection signal detected by the operating status detecting section 8 is sent to the concentration state discriminating section 9, the degraded service floor detecting section 10, and the two-way call detecting section 12. When this signal is received, the concentration state determination unit 9 detects whether the destination floors of users are concentrated on a specific floor, for example, whether there are many people getting off at the specific floor. In addition, the floor with degraded service determining unit 10 detects a floor where the service for the user is degraded in the assigned call, for example, when the duration of the landing call is longer than a predetermined value. There is. The detection signal detected by the concentration state determination section 9 is sent to the response elevator assignment section 11 via the service degraded floor detection section 10.

The response elevator assignment unit 11 is capable of inputting and outputting signals to and from the single control circuits 5b1 to 5bm via the high-speed transmission line 7, and further includes:
Signals can be input/output between the hall call input/output control units 2a1 to 2an shown in FIG. 9 and the monitoring panel 6 via the low-speed transmission line 3.

The bidirectional call detection unit 12 detects whether or not there is a landing call in the opposite direction to the service lowering direction call on the service floor. The elevator notification means causes a landing lantern (not shown) to display a different display than usual, for example, flashing in both directions, and also notifies the car driving direction when the elevator door is opened.

Next, the operation in FIG. 1 will be explained with reference to the schematic diagram for explaining the operation in FIG. 2 and the flowcharts in FIGS. 3 and 4. In state 1 of FIG. 2(a), the elevator car 15
This figure shows a case in which a reverse response is made to the f3 floor upon detection of a lower service floor from a state in which f1, f2, and f3 have already been assigned at the time of departure.

First, in FIG. 3, the operating status detecting section 8 detects the operating status of each elevator, that is, the traffic demand, from the single control circuits 5b1 to 5bm, etc. (step G10). Based on the detection in step G10, the concentration state determining unit 9 determines whether or not the target floor of the users of each floor is concentrated at a certain level or more on a specific floor such as the cafeteria floor (step G20). ). In this case, the determination conditions are as follows:
A certain percentage or more is related to a specific floor, and
A possible condition is that the average arrival load on a specific floor exceeds 70%, for example.

When the concentration state determining unit 9 determines that the user is in a concentrated state, a special operation according to the present invention as described below is executed. The service degraded floor detection unit 10 extracts the service degraded floors (step G
30). Conditions for determining a floor with degraded service may include conditions such as an unloaded cargo having occurred during the previous response, and the duration of a landing call being longer than a predetermined value. The bidirectional call detection unit 12 detects whether or not there is a call in the direction of reduced service and a landing call in the opposite direction on the service floor.

According to state 1 in FIG. 2(a) described above, if the landing call is for a floor with reduced service as shown in FIG.
After detecting from the information whether or not the car 15 has departed from a specific floor (step G60), a reverse direction response command is issued to the assigned car in response to the call (step C70), and together with the single control circuit 5b1, the car 15 is sent to the lower service floor. Performs a reverse response function with respect to the floor. Specifically, when moving in the opposite direction (up direction) to the already allocated service lowering floor on the f3 floor,
f3 Gives a command to respond to a call in the down direction on the 3rd floor. Outputting the reverse direction response command to such floors with degraded service is performed for all cars 15 (step G80).
, G40).

The single control unit 5a1 executes an operation corresponding to the reverse direction response command from the response elevator assignment unit 11 according to the flowchart of FIG. Figure 2 (
As shown in state 2 of b), for the f3 floor, it is determined whether it is the opposite direction landing response command floor (step S1),
The car is decelerated when the opposite direction landing response command floor is selected, that is, when the up direction is selected (step S2). At this time, d
While erasing the f3 floor call in the own direction (step S3), the arrival notification in the opposite direction is executed by flickering the down direction platform lantern (step S3).
4). In this case, since there is a landing call in the up direction on the f3 floor, the landing lantern in the up direction also flickers at the same time through normal response processing in step S3, and the landing call in the up direction is also erased.

Therefore, as shown in state 2 in FIG. 2(b), the hall lanterns in both the up and down directions are in a flickering state, and the hall calls are erased in both the up and down directions.

[0034] However, at the time when the car door opens (step S5), since the landing lanterns in both directions for the passenger waiting at the landing are flickering, the driving direction of the car is unknown, so the forward direction landing is assigned. If there is a command (step S6), a guidance notification command is executed to notify the driving direction of the car (step S7). A specific example of the execution of this guidance notification command is “up
Possible options include "We're heading in the direction you want to go" and "Customers heading in the direction "Down" should also get on board.

[0035] By doing this, passengers waiting in both directions at the f3 floor platform can know that boarding is being guided by the platform lantern, and the car driving direction can also be determined by the car direction guidance notification when the door is opened. They can be recognized at the same time, so even if the car is guided in a different manner than usual, there will be no confusion, and passengers waiting at the platform can board the car.

After the passenger boards the f3 floor, the direction selection is determined at the car departure timing (step S8). f
When boarding on the third floor, if the car load is full (step S9) and there is no in-car destination call (car call) in the car movement direction (up direction) (step S10), the car is loaded in the car movement direction (up direction). ) direction selection is not necessary, so
Direction selection is performed in the direction of a specific floor (step S11)
. On the other hand, in cases other than the above, Fig. 2 (
As shown in state 3 of c), the car traveling direction (up direction)
Hold the direction selection and select the destination call floor in the car, or f1.
A response is made to the floor (step S12).

In this case, for the landing passengers on the f3 floor, in state 2 in FIG.
Confusion can be prevented by notifying passengers on the f3 floor that the car is in a special operation state by providing a voice or display to notify passengers that the car will "temporarily ascend" (step S13). .

As described above, according to the first embodiment of the present invention, at a special time such as the first half of the lunch period,
When transporting users to a specific floor such as the cafeteria floor, it is possible to equalize the service on each floor without reducing the usability of passengers waiting at the platform, and to increase the efficiency of transportation to the cafeteria floor. can.

Next, regarding the second embodiment of the present invention, FIG.
This will be explained with reference to a schematic explanatory diagram of the operation and a flowchart of FIG. 6. Here, the same parts as in the first embodiment described above are given the same reference numerals, and only the different points will be explained. In the first embodiment, the elevator notification means is to flash the landing lanterns in both directions when the elevator assigned to the floor with reduced service is called in the opposite direction to the specific floor, and to In contrast, this embodiment is configured as follows. That is, in this embodiment, the elevator notification means is configured to notify the elevator assigned to the floor with reduced service when there is a landing call in the opposite direction to the specific floor.
In addition to flashing the landing lantern to indicate only the driving direction of the car, when the door is opened, a notification is provided to guide passengers toward the lower service floor.

The above operation is performed by the single control unit 5 corresponding to the reverse direction response command by the response elevator assignment unit 11 in FIG.
This is done by another operation of a1. Figure 5(b)
Due to state 2, deceleration is performed for the f3 floor when the reverse direction, that is, the up direction is selected (step S2 in Fig. 6).
. At this time, the f3rd floor call in the down direction is deleted (step S3). Since there is also an up direction landing call on the f3 floor, the up direction landing lantern is flickered by normal response processing and the up direction landing call is also deleted (step S3).

Therefore, as shown in state 2 of FIG. 5(b), the platform lantern in the up direction becomes in a flickering state,
In addition, the boarding place calls are deleted in both the up and down directions.

[0042] Then, the car door opening timing (step S
5) For passengers waiting at the platform, the up direction platform lantern is in a flickering state, so the service is called in the direction of the lower floor, that is, the passenger waiting at the platform in the down direction is not guided, so the forward direction platform assignment is If there is a command (step S6), a guidance notification command for guiding passengers waiting in the down direction to board the platform is output (step S20). A specific example of this guidance notification command is “do
"Customers heading in the wn direction, please also ride." could be considered.

[0043] In this way, passengers waiting in the down direction of the f3 floor platform can recognize the boarding guidance of the car by the boarding guidance notification when the car door is opened, and can board the car without causing confusion. Can be done. The following operations are similar to those of the first embodiment described above.

Next, regarding the third embodiment of the present invention, FIG.
This will be explained with reference to a schematic explanatory diagram of the operation and a flowchart of FIG. 8. Here, the same parts as in the first embodiment described above are given the same reference numerals, and only the different points will be explained. In the first embodiment, the elevator notification means is to flash the landing lanterns in both directions when the elevator assigned to the floor with reduced service is called in the opposite direction to the specific floor, and to In contrast, this embodiment is configured as follows. That is, in this embodiment, the elevator notification means is configured to notify the elevator assigned to the floor with reduced service when there is a landing call in the opposite direction to the specific floor.
In addition to flashing the landing lantern only in the direction of the lower service floor, when the car door is opened, a guidance notification is provided to guide passengers in the direction of car operation.

The above operation is performed by the single control unit 5 corresponding to the reverse direction response command by the response elevator assignment unit 11 in FIG.
This is done by another operation of a1. Figure 7(b)
Due to state 2, for the f3 floor, deceleration is performed in the opposite direction, that is, when the up direction is selected (step S2 in FIG. 8).
. At this time, erase the f3rd floor call in the down direction and flicker the platform lantern in the down direction (
Step S3), the car executes a reverse direction arrival notification command (Step S4). At the same time, in order to give priority to boarding guidance for passengers waiting in the down direction, a command is output to prevent notification of the arrival of cars in the forward direction, that is, in the up direction (step 30).

Specifically, the up direction platform call is deleted, but the flicker of the up direction platform lantern is not performed. Therefore, as shown in state 2 of FIG. 7(b), dow
Only the platform lantern in the n direction flickers. Do to customers waiting at the platform when the car door opens.
Since only the wn direction platform lantern is in a flickering state, the car driving direction is not called, that is, boarding guidance is not given to passengers waiting in the up direction. A guidance notification command for guiding passengers waiting at the platform to board the train is output (step S31). A specific audio example of this guidance announcement command is: ``Customers heading in the up direction also please board the vehicle.''
etc. are possible.

[0047] In this way, passengers waiting in the up direction of the f3 floor platform can recognize the boarding guidance to the car by the boarding guidance notification when the car door is opened, and can board the car without causing confusion. be able to. The following operations are similar to those of the first embodiment described above.

[0048]

[Effects of the Invention] According to the present invention, when the destination floors of users are concentrated on a specific floor, transportation efficiency is maintained, the services on each floor are equalized, and the usability for passengers waiting at the boarding area is improved. It is possible to provide an elevator group management control device that does not cause deterioration.
