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 device used for operating a plurality of elevators between a plurality of floors.

[0002]

2. Description of the Related Art In recent elevator systems, in order to improve the operating efficiency of a plurality of elevators arranged side by side and to improve the service to elevator users, elevators that respond to hall calls on each floor are provided with a microcontroller. The assignment is made reasonably and quickly using a computer.

[0003] That is, when a hall call occurs, the group management control device selects and allocates an optimum elevator to be serviced for the hall call from a plurality of elevators, and responds to the hall call to other elevators. I try not to let them.

[0004] At the elevator landing, a display lamp (landing lantern) installed near the entrance of the assigned elevator is turned on, and immediately before the elevator arrives, the lamp flashes together with the chime. It has become.

Further, in such an elevator system, with the recent development of microcomputers, measurement of car call registration data or loading / unloading load data when responding to each elevator landing is performed in real time, and each floor is measured. The traffic flow between floors is being grasped.

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

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

The group management control unit 4 is connected to the individual control units 5a1... 5am installed in each elevator and the monitoring panel 6 installed in the monitoring room via the low-speed transmission line 3. The control unit 4 and the single control units 5a1 to 5am are also connected by a high-speed transmission line 7.

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

[0010] For example, if the optimum elevator is the elevator (hereinafter referred to as the "first unit") related to the single control unit 5a1, the group management control unit 4 sends an assignment command signal to the single control unit 5a1. Then, a landing lantern (not shown) installed near the entrance of the first elevator is turned on. By lighting this landing lantern,
It can be understood that the user waiting on the nth floor only needs to wait in front of the entrance door of the first elevator among the plurality of entrance doors.

By the way, in a building where a dining room is installed on a specific floor, traffic demand for the specific floor extremely rises during a special time zone such as the first half of the lunch break. Therefore, in such a special time zone, better transport efficiency is required as compared with a normal time zone.

[0012] Here, the case where good transportation efficiency is performed means that an elevator heading to a specific floor receives a floor call assigned to each floor until it reaches the specific floor, so that each of these floors is filled up. It means that the service on each floor is equalized without passing through the floor as it is, and when it reaches the specific floor, it is almost full or almost full.

In the conventional elevator group management control device,
In order to secure good transportation efficiency as described above, when an elevator is assigned to a landing call on each floor, the load on the floor where the elevator stops is predicted together with the predicted non-response time described above. As the elevators are full, we try to minimize the chance of passing through the floor to be stopped. That is, basically, the assignment control is performed so that the user gets on the elevators that are in operation as evenly as possible.

As described above, when a floor call occurs on each floor, elevators are assigned in anticipation of users getting on from these floors, but traffic demands are directed toward the specific floor. At the peak when the traffic rises extremely, since the number of waiting customers per call is not one, there are many calls on the f1 and f2 floors and the second floor as shown in FIG. Assuming that the predicted load is 16 people and the car loading load is 24 people, the f2 floor will not be fully packed, and the other units (Nos. 1 and 2) have a long predicted response time and 3 If you assign it to a machine other than
Unit 3 carries 16 people and comes to the cafeteria floor, which is unfavorable in terms of transportation capacity. Therefore, there are cases where units are assigned to Unit 3 by relative evaluation.

[0015] Assuming that the number of waiting passengers at each floor of the floors f1 and f2 is 16 in accordance with the prediction, on the floor f1, 1
Six people can get on, but only eight people can get on the f2 floor, which is not preferable from the viewpoint of uniform service on each floor.

[0016]

As described above, even if the assignment is made in consideration of the load prediction, the number of passengers on the elevator is not limited in the case where there are many waiting persons at the floors as described above. In general, a floor farther than a specific floor is advantageous, and a floor near the specific floor tends to be disadvantageous.
If the number of passengers is limited as described above, equalization can be realized, but it is practically difficult from the viewpoint of user convenience.

For this reason, when the destination floor of the user is concentrated on a specific floor, the service is allocated to the lowered service floor with the aim of equalizing the service of each floor while maintaining the transportation capacity. A system has been already filed in which the elevator responds in the opposite direction to the specific floor when operating the vehicle (Japanese Patent Application No. 2-260482).

For example, in FIG. 10, if responses are made in the order of the f1 floor and the f2 floor at a certain time, the f2 floor is raised as a service lowering floor (u
p) means that the vehicle responds in the direction driving, and responds in the order of the f2 floor and the f1 floor. However, as shown in FIG. 11, at the f2 floor, in the opposite direction to the service lowering floor, that is, when Unit 3 has already assigned an up-direction hall call, the specific floor is operated on the f2 floor when operating in the up direction. If a direction call, that is, a down direction call is answered, a phenomenon that the passenger in the landing is confused cannot be identified by the landing lantern alone, which passenger is being guided.

Therefore, the present invention is to maintain the transportation efficiency when the destination floor of the user is concentrated on a specific floor, to equalize the services of each floor, and to reduce the usability of the waiting passengers at the landing. It is an object of the present invention to provide an elevator group management control device that does not have any problem.

[0020]

According to the present invention, in order to solve the above-mentioned problems, a plurality of elevators are operated between a plurality of floors, and any one of the plurality of elevators is operated by a user from each floor to a landing call. In the elevator group management control device, the operation status detection means for detecting the operation status of the elevator, and the destination floor of the user based on the detection result of the operation status detection means. State determination means for determining whether or not is concentrated on a specific floor, and when the concentration state determination means determines that the state is concentrated, the service level for the user is reduced. A service lowering floor detecting means for detecting a floor, and an elevator assigned to the service lowering floor detected by the service lowering floor detecting means. An elevator response means for responding to the service lowered floor during reverse operation, and a two-way call detection means for detecting that there is a landing call in the opposite direction to the specific floor on the floor with the service level reduced, When the elevator assigned to the service lowered floor has a hall call in the opposite direction to the specific floor, the hall indicator is displayed in a display form different from the normal display mode, and the operating direction of the car when the car door is opened or Elevator notification means for providing guidance for passenger guidance.

[0021]

In the above means, the operating status detecting means detects the operating status of each elevator. Based on this detection, when the operating status exceeds a certain level, the concentrated status determining means determines the destination floor of the user. Is determined to be concentrated on a specific floor.

When it is determined that the user is in a concentrated state,
The service lowered floor detecting means selects a floor in which the service level for the user is reduced in the assigned call. The elevator responding means causes the elevator assigned to the service level lowered floor to respond to the service lowered floor when the elevator is operating in a direction opposite to the specific floor.

In this case, the two-way call detecting means detects that there is a hall call in the opposite direction to the specific floor, and if there is a hall call in the opposite direction by the elevator notifying means, the hall indicator is set to normal. It is displayed in a different form and guides the passengers waiting for the landing when the car door opens. Therefore, the above object can be achieved.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a configuration of a main part of the present embodiment. An operation status detection unit 8 is provided in the group management control unit 4, and the operation status detection unit 8 is connected to the single control unit 5a1 via the low-speed transmission line 3 and the high-speed transmission line 7.
The operation status of each elevator, for example, the contents of the call registration in the car of each elevator, etc., is detected from the single control circuits 5b1-5bm within ~ 5am.

The detection signal detected by the operation status detecting unit 8 is sent to a concentration state determining unit 9, a service lowered floor detecting unit 10,
The call is sent to the two-way call detection unit 12.
Then, upon receiving this signal, the concentration state determination unit 9 detects whether the user's destination floor is concentrated on the specific floor, for example, whether or not the number of getting off the specific floor is large. In addition, the service-decreased floor determination unit 10 detects a floor in a state where the service to the user is reduced during the assigned call, for example, when the duration of the hall call is equal to or longer than a predetermined value. I have. The detection signal detected by the concentration state discriminating unit 9 is transmitted to the response elevator allocating unit 11 via the service degradation floor detecting unit 10.

The response elevator allocating section 11 can input and output signals to and from the single control circuits 5b1 to 5bm via the high-speed transmission line 7. Hall call input / output controller 2a1
Signals can be input and output between .about.2an and the monitoring panel 6.

The two-way call detecting unit 12 detects whether or not there is a hall call in the service floor in the opposite direction to the service lowering direction call. The elevator notification means displays a landing lantern (not shown) different from the usual display, for example, blinks in both directions, and provides guidance of the car driving direction when the elevator door is opened.

Next, the operation of FIG. 1 will be described with reference to the schematic operation explanatory diagram of FIG. 2 and the flowcharts of FIG. 3 and FIG.
In the state 1 in FIG. 2A, the specific floor is the elevator car 15.
Shows a case in which a response is made in the reverse direction from the state where f1, f2 and f3 have already been allocated at the time of departure to the floor f3 where the service-decreasing floor is detected.

First, referring to FIG.
Detects the operating status of each elevator, that is, the traffic demand from the single control circuits 5b1 to 5bm (step G1).
0). Based on the detection in step G10, the concentration state determination unit 9 determines whether or not the user's target floor on each floor is concentrated on a specific floor such as a dining floor at a certain level or higher (step G20). ). The determination conditions in this case include:
Regarding the hall call direction and the car call registration of each floor, it is conceivable that conditions for specific floors are not less than a certain percentage and that the average arrival load at the specific floor exceeds 70%, for example.

When the concentration state discriminating section 9 determines that the state is concentrated, a special operation according to the present invention as described below is executed. The service degradation floor detection unit 10 extracts the service degradation floor (step G).
30). As conditions for determining the service-decreasing floor, there may be conditions such as unloading at the time of the previous response and the duration of the hall call being equal to or longer than a predetermined value. The two-way call detection unit 12 detects whether or not there is a hall call in the service floor in the opposite direction to the service lowering call.

According to the above-mentioned state 1 of FIG. 2A, the response elevator allocating unit 11 determines that the hall call is on the service lowering floor as shown in FIG. 3 (step G50).
After detecting whether or not the car 15 has departed from the specific floor from the information (step G60), it issues a reverse response command to the assigned car in response to the call (step C70), and together with the single control circuit 5b1, the service lowering floor. Performs a reverse response function to the floor. More specifically, a command is issued to respond to a down direction call on the f3 floor when the service is in the reverse direction (up direction) with respect to the allocated service lowering floor on the f3 floor.
Outputting the reverse response command to such a service lowering floor is performed for all cars 15 (step G8).
0, G40).

The single control unit 5a1 executes an operation corresponding to the backward response command from the response elevator allocating unit 11 according to the flowchart of FIG. FIG. 2 (b)
As shown in state 2, it is determined whether or not the floor f3 is the reverse landing response command floor (step S1). When the floor is the reverse landing response command floor, that is, when the up direction is selected, the car is decelerated. (Step S2). At this time, down
Deletes the f3 floor call in the direction (step S
3) Flick the down direction landing lantern to execute the backward arrival notification (step S).
4). In this case, since there is a hall call in the up direction on the floor f3, the hall lantern in the up direction is simultaneously flickered by the normal response processing in step S3, and the hall call in the up direction is also deleted.

Accordingly, as shown in state 2 of FIG. 2B, the landing lanterns in both the up and down directions are in a flicker state, and the landing call is in a state where both the up and down directions are erased.

At the car door opening timing (step S5), since the landing lanterns in both directions are in a flicker state with respect to the waiting passengers, the driving direction of the car is unknown. If there is a command (step S6), a guidance notification command for notifying the driving direction of the car is executed (step S7). The execution of the guidance notification command is performed by voice as a specific example of “up
Direction "and" please ride in down direction ".

In this way, the waiting passengers in both directions of the f3 floor landing can know that the boarding guidance has been made by the landing lantern, and the car driving direction can be changed by the car direction guidance when the door is opened. They can be recognized at the same time, and even if the guidance mode is different from normal, it will not cause confusion, and the passenger waiting for the landing can get into the car.

After the passenger has boarded the f3 floor, a direction selection is determined at the car departure timing (step S8). f3
On the floor, the car loading load becomes full (step S
9) If there is no car destination call (car call) in the car traveling direction (up direction) (step S10), it is not necessary to select the direction of the car traveling direction (up direction). A direction is selected (step S11). On the other hand, in cases other than the above, FIG.
As shown in state 3, the direction selection is held in the car traveling direction (up direction), and a response is made to the in-car destination call floor or the f1 floor (step S12).

In this case, for the landing passenger on the f3 floor, in state 2 in FIG. 2 (b), the flickering of the landing lantern provides guidance to the specific floor direction.
The guidance in the car indicating "to go up once" is notified by voice or display (step S13), and confusion can be prevented by notifying the passenger on the f3 floor of the special driving state that the vehicle is in the special driving state. .

As described above, according to the first embodiment of the present invention, at a special time such as the first half of the lunch time zone,
When transporting users to a specific floor such as the dining floor, it is possible to equalize the services on each floor without reducing the usability of the waiters at the landing, and to increase the transportation efficiency to the dining floor. it can.

Next, a second embodiment of the present invention will be described with reference to FIG.
The operation will be described with reference to FIG. 6 and the flowchart of FIG. 6. Here, the same portions as those in the first embodiment are denoted by the same reference numerals, and only different points will be described. In the first embodiment, as the elevator notifying means, when the elevator assigned to the service lowering floor has a hall call in the opposite direction to the specific floor, the hall lantern flashes in both directions and the car is opened when the car is opened. In this embodiment, the following is performed while the guidance notification of the driving direction is performed. That is, in the present embodiment, as the elevator notification means, when there is a landing call in the opposite direction to the specific floor, the elevator assigned to the service lowering floor is:
The landing lantern blinks only the driving direction of the car, and performs guidance notification of passenger guidance in the direction of the service lowering floor when the door is opened.

The above operation is performed by the single control unit 5 corresponding to the backward response command by the response elevator allocating unit 11 of FIG.
Performed by another operation of a1. According to the state 2 in FIG. 5B, the direction opposite to the f3 floor, that is, u
When the p-direction is selected, deceleration is performed (step S2 in FIG. 6). At this time, the f3 floor call in the down direction is deleted (step S3). Since there is also an up hall call on the f3 floor, the up hall lantern is flickered by normal response processing, and the up hall call is also deleted (step S3).

Therefore, as shown in the state 2 of FIG. 5B, the landing lantern in the up direction is in a flicker state, and the landing call is erased in both the up and down directions.

Then, the car door opening timing (step S
In step 5), since the landing lantern in the up direction is in a flicker state with respect to the waiting passenger in the up direction, the service is not called in the direction of the lowered floor, that is, the passenger waiting for the waiting passenger in the down direction is not performed. If there is a command (step S6), a guidance notification command for guiding the passenger waiting at the landing in the down direction is output (step S20). As a specific example of this guidance notification command, "do
Please get on the customer in wn direction. "

As described above, the waiting passenger in the down direction of the landing on the f3 floor can recognize the guidance of the car by the guidance of the guidance of the car when the car door is open, and can get on without causing confusion. Can be. The following operation is the same as in the first embodiment.

Next, a third embodiment of the present invention will be described with reference to FIG.
