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 device having a guide display device in an elevator hall on each floor.

[0002]

2. Description of the Related Art In a conventional group management control system, when a hall call is registered in an elevator hall in order to provide efficient elevator service with a plurality of elevators, each elevator will arrive for that call. The "hall call assignment method" is used to determine the elevator that is most suitable for the service based on the evaluation value such as time.

In this "hall call assignment system", in order to reduce waiting time for passengers in the hall and boarding time in the car, "elevator passes through hall call" and "elevator far from hall call" Hall call allocation control of "allocating".

A reservation light or an arrival light is provided in the hall in such a group-controlled elevator to notify the service of the elevator. However, only the reservation light or the arrival light tells the passengers of the hall "where is the elevator?"I'm worried because I don't know how long I can wait to get on. Therefore, even in a building with a small number of elevators or a building with a large number of elevators, a car position indicator of the elevator may be installed in addition to the reservation of halls and arrival lights depending on the customer's request. In this case, all the car position indicators in the hall are constantly lit, so the above-mentioned phenomenon of "elevators passing hall calls" and "assigning distant elevators to hall calls" Since it was visible to the user through the container, it sometimes caused the user to feel distrust and frustration.

Several proposals have been made to solve this problem.

Japanese Patent Laid-Open No. 56-28173 discloses a group-controlled elevator in which a car position indicator is installed on all elevators, and the floors where the elevators are scheduled to stop in response to a car call or hall call. Describes that the position of the elevator is displayed.

Japanese Utility Model Laid-Open No. 52-159569 discloses a group management elevator in which car position indicators are installed on all elevators, and the car position indicators are always lit, at the time of hall call registration, It is stated that the car position display is continued only for the elevators servicing this hall call, and the car position indicators of other elevators are turned off.

[0008] According to Japanese Utility Model Laid-Open No. 1-159683, the car position is provided on condition that the planned service elevator has approached the hall call by a predetermined distance and that the scheduled arrival time at the registered hall call is within a predetermined time. The method of displaying is described.

In Japanese Patent Laid-Open No. 192686/1989, a device for generating a virtual hall call is provided at a landing on each floor at a certain time or when necessary in the vertical direction of all floors, and an elevator for servicing the virtual hall call is provided. It is described that, together with the elevators that have been assigned and serviced to call existing halls, the car position and the moving direction of each elevator at that time are displayed together.

[0010]

On the condition that the elevator car position is displayed on the condition that the hall call on each floor is registered, the car position is displayed until the hall user presses the hall button. I haven't been. Therefore, a customer who wants to move between floors in a hurry presses the hall button to display the car position on the hall display in order to determine whether or not to use the elevator. In this case, if the assigned elevator is far from the floor,
Since the passenger who presses the hall button uses the stairs and the escalator, there were times when there was no passenger at the platform when the elevator serviced.

Contrary to the above, on the condition that the hall call of each floor is registered, in the case where the elevator car position display other than the elevator assigned to the hall call is extinguished, "this elevator will come". Guess,
There was a problem that turning off the car position display was a betrayal act for waiting customers.

[0012] In both cases, the elevator serving the registered hall call is determined irrespective of the standing position of the passengers at the landing. Therefore, when a plurality of elevators are arranged side by side Occasionally, passengers would have to travel long distances in front of the service elevator when the elevator was assigned far away from where the customer was standing.

In the case where the car position is displayed on the condition that the planned service elevator has come close to the hall call by a predetermined distance and the scheduled arrival time at the registered hall call is within the predetermined time, the distance of the elevator Since there is no building and it is crowded, there is a problem that after the car position is displayed, the car is full and the floor where the car position is displayed cannot be serviced. there were.

In a virtual display of hall calls on all floors and the car position and moving direction of both the service elevator of the virtual hall call and the service elevator of the registered hall call are displayed together, a plurality of elevators are placed in the hall. Since the position is displayed, there is a problem that it is likely to cause confusion among users.

It is an object of the present invention to guide the passengers to the service elevator by guiding the passengers to the hall in advance, such as the position of the car and the degree of congestion in the car, before the user of the hall presses the hall button. By setting the guidance display implementation / non-implementation zone on the floor and restricting the floors that display the guidance display, it is notified that the elevator near the floor where the customer is will be serviced, and the annoyance due to the long waiting of the customer is reduced. By assigning the hall call to the elevator displaying the guidance when registering the hall call,
The purpose is to display a reliable guide.

[0016]

[Means for Solving the Problems] The objects are a plurality of elevators servicing a plurality of floors, a control device for controlling the elevators, and a hall call registration device for calling an elevator in an elevator hall of each floor. A service status guidance display device installed near the entrance of each elevator on each floor, and an elevator group management control device having allocation means for allocating an elevator to service the registered hall call, wherein the service status guidance display device Display selecting means for selecting a service status guidance display device for displaying guidance of operation status or general information from among the above, means for displaying guidance of operation status or general information on the service status guidance display device selected above, and the hall After call registration, the service status guide display device on the floor The guidance display to have the elevator is achieved by providing a service elevator selecting unit preferentially selected assigned to.

[0017]

Operation: The display elevator selecting means limits the number of elevators to be displayed for guidance on each floor and the floor for which the guidance is displayed. In addition, according to the operation status of the elevator on the service status guidance display device selected in the display selection means,
Display information on elevator operation status or general information. After registering the hall call, the service elevator selecting means preferentially selects the elevator displaying the guidance on the service status guidance display device on the floor and allocates the hall call. Through these efforts, we will improve the service to our customers.

The hall call assignment program P06 selects an elevator to which the hall call is assigned from the conditions of various tables T03 and the guidance display execution / non-execution zone table T02 when a new hall call or a reallocation hall call is generated in the hall call table T04. And assign. The allocation result is stored in the hall call allocation table T06. Further, a service floor setting table T07 is created based on the information of the guidance display execution / non-execution zone setting table T02, various tables T03, and hall call table T04, and together with the allocation table T06, the group / unit transmission program P07 is used to generate the number of units. Send to controller.

A command for displaying a guide in the guide display execution zone is created by the display command command processing program P08. The created display command is displayed in the display command table T0.

FIG. 2 is a flow chart showing an embodiment of guidance display execution / non-execution zone setting processing.

Basically, the guidance display execution zone is set in the traveling direction of each elevator, and the guidance display non-execution zone is set in the opposite direction to the traveling direction of each elevator.

Consider setting a guidance display execution / non-execution zone for a certain elevator a and a succeeding elevator b immediately after the elevator a, out of a plurality of elevators, based on the temporal position intervals of the elevators a and b.

First, in step S12, temporally equidistant position data of the elevators a and b are calculated. As a result, the reference time interval D, which is the reference for the guidance display priority zone set for each elevator, is calculated in step S13 based on the position intervals dtab at equal time intervals between the elevators.

Next, in step S14, the position intervals dtab at equal time intervals are compared with the reference time interval D.

When the position intervals dtab at equal time intervals are longer than the reference time interval D, the leading floor Fsa of the guidance display priority zone of the elevator a is set to the position Fa of the elevator a in step S15.

When the position intervals dtab of the respective electric elements at equal time intervals are shorter than the reference time interval D, the guidance display priority zone of the elevator b overtakes the position Fa of the elevator a, so that the guidance display priority of the elevator a is given. In order to determine the first floor Fsa of the zone, it is necessary to consider the guidance display priority zone of the elevator b. In consideration of the above, in step S16, the position FbD obtained by adding the position f (D) obtained by converting the reference time interval D to the number of floors to the position Fb of the elevator b immediately after is calculated. In step S17, it is determined whether or not there is a hall call or car call for the elevator a between the positions Fa and FbD of the elevator a. If there is no call, the leading floor Fsa of the guidance display priority zone of the elevator a is set to FbD in step S19. If there is a call, in step S18, the first floor Fsa of the guidance display priority zone of the elevator a is this elevator a.
It is assumed that the floor Fay with a call is closest to the position Fa. In step S20, the position F of the elevator a is
The area from a to the leading floor Fsa of the guidance display priority zone is set as the guidance display suppression zone and set in the guidance display execution / non-execution zone setting table T02.

In steps S15, S18 and S19, the leading floor Fsa of the guidance display priority zone of the elevator a is displayed.
Then, in step S21, the reference time interval D is added to the leading floor Fsa of the guidance display priority zone of the elevator a.
Is added to the number of floors, and the position f (D) is added to obtain the final floor Fea of the guidance display priority zone of the elevator a. In step S22, this Fsa to Fea is set as the guidance display priority zone and set in the guidance display execution / non-execution zone setting table T02.

In step S23, the general information display zone is set from the floor next to the final floor Fea of the guidance display priority zone to the end floor in the traveling direction of the elevator, and the guidance display holding zone is set in the direction opposite to the traveling direction of the elevator. -Set in the non-implementation table T02. Step S14
It is determined in step S25 whether or not the processes from to S24 are completed for all elevators, and the process is repeated until all elevators are completed.

FIG. 3 shows an example of the guidance display execution / non-execution zone table.

A specific example in which the processing shown in the flow chart of FIG. 2 is carried out will be described with reference to FIG. 4 in which the number of elevators is 4 and the number of service floors is 12. Elevator Unit A EA is now on the 5th floor, Elevator Unit B EB is on the 8th floor,
Elevator C EC moves up on the second floor,
It is assumed that elevator No. D ED is traveling down the 9th floor. In this state, the guide display priority zones Z1A, Z1B, Z1C, Z1D of each elevator, part of the display contents, for example, the guide display suppression zones Z2A, Z2B, Z2D for restricting the display of the car position, the general information display zones Z3A, Z3B, The settings of Z3C, Z3D, and the guide display holding zones Z4A, Z4B, Z4C, Z4D are considered in the order of elevator No. D ED, No. C EC, No. A EA, No. EB.

Now, let us say that the value obtained by converting the reference time interval D calculated in the guidance display execution / non-execution zone setting program into the number of floors is five floors. Elevator Unit D ED and Unit C EC are located on the 9th floor, so elevator D
Elevator D to guide display priority zone Z1D of Unit ED
Set from the 9th floor of Unit ED to the 5th floor in the down direction. Elevator C EC and A A EA are located on the third floor. The guide display priority zone Z1C of the elevator C EC is set from the position of the elevator C EC 2nd floor to the 6th floor in the up direction. Since the elevator position interval is shorter than the 5th floor, elevator A EA
Of the guide display priority zone Z1A from the 7th floor to the 11th floor, and the guide display suppression zone Z2A of the elevator A No. EA is 5
It will be set from the first floor to the sixth floor. Further, the distance between the elevators A and B is on the third floor, and the assigned hall call HB of the elevator B is also taken into consideration. Therefore, the guide display priority zone Z1 of the elevator B EB is considered.
B is set from the 10th floor to the 12th floor, and the guidance display suppression zone Z2B of the elevator No. B is set from the 8th floor to the 9th floor. For each elevator, the general information display zone (Z3A, Z3B, Z3C, Z3D) extends from the floor next to the last floor of the guidance display priority zone to the end floor in the traveling direction, and the guidance reservation zone (Z4A, Z4B, Z4C, Z4
D).

On the hall guide display device of each elevator, the following guide displays are provided for each zone set above. Guidance display priority zone (Z1A, Z1B, Z1C, Z
1D), elevator car position and driving direction (HY1
-A, B, C, D), general information display zone (Z3A,
Z3B, Z3C, Z3D), the current time (HY3-
A, B, C, D) are displayed. Information display suppression zone (Z
2A, Z2B, Z2D), guidance display reservation zone (Z4A,
Z4B, Z4C, Z4D) is only the driving direction or is not displayed (HY4-A, B, C, D). Also, regarding elevators A and B, the guidance display priority zones Z1A and Z1B overlap on the 10th and 11th floors, and displaying the car positions for both cars may lead to confusion for hall users. For this reason, the number A EA, which is far from the elevator, displays only the driving direction (HY2-A).

The display status of each floor in various operating states of each elevator will be described with reference to FIGS. 5, 6 and 7.

FIG. 5 is an example of a display for the middle floor (example of the sixth floor). In pattern a1, elevator B (hereinafter B
No.) and an elevator No. D (hereinafter No. D) are near the 6th floor, so the car position and driving direction are displayed respectively, and the elevator No. C (No. C below) is farther than No. B, so the time is displayed and the elevator Unit A (hereinafter Unit A) is 11
There is a situation where you are moving away from the floor because you are traveling upward, and there is no display because it is far away. Hall calls are assigned to Unit B in the same direction (with waiting time display). In pattern a2, Unit B and Unit D are in the middle of servicing the cafeteria floor (7th floor), and “service in cafeteria floor” and “car position / driving direction” are displayed alternately. Since car B is crowded in the car and is almost full, we avoid guiding passengers to car B in the car congestion display. Since Unit A is near the 6th floor next to Unit B, the car position and driving direction are displayed to guide the passengers to Unit A. Pattern a3 shows a case where the building is in a time zone when there are few users. In this case, since the car No. C is waiting on the 6th floor, the car position of the car No. C is displayed and the customer is guided. Other units are not displayed.

FIG. 6 shows an example of a display for the upper floors (example of the 11th floor).
Is. In the pattern b1, No. A, No. B and No. C are displayed. Units B and C show that they are traveling upward on the 10th and 9th floors, respectively. Since Unit B is closer to the 11th floor than Unit C, the downhaul call generated on the 11th floor is assigned to Unit B. Unit A displays the time because it is farther than Units B and C. In the pattern b2, No. A, No. C and No. D are displayed. Since Unit A is closed on the 12th floor and operates directly to the lobby, "Direct to Lobby" and "Cage Position" are displayed alternately. The generated downhaul call is assigned to Unit C, which can service the earliest. Unit D is running on the 5th floor and displays the time. In the pattern b3, the car No. B and the car No. D respectively display the car position, the driving direction, and the service direction. In Units B and D, Unit D is closer to the 11th floor, but Unit D has a car call on the 12th floor, and the arrival at the downhole call on the 11th floor is delayed, so
Unit D displays many waiting times, and hall calls are assigned to Unit B.

FIG. 7 is an example of the display for the lower departure floor (example of the first floor). The pattern c1 is the case where the departure floor is crowded, and all the units A to D display. The car positions are displayed because Units A and B are near the first floor. The pattern c2 is a case where the divided express operation is performed by the A and B units and the C and D units. All of A, B, C, and D units alternately display the service floor and the running display, and the elevator near the first floor displays the car position.

An example of hall call allocation according to the contents of the guide display will be described with reference to FIG. In Fig. 8, the display status of the four elevators is that the elevator A EA only displays the driving direction, the elevator B EB displays the driving direction and the car position, the elevator C EC displays the time, and the elevator D ED does not display. Suppose there is. In this state, when a new hall call is generated, the guide display priority allocation processing causes the elevators to which the new hall call is allocated to display elevator guides, elevators A and EA.
It is selected from No. EB and No. C EC. as a result,
Normally, a new hall call is a machine with a lot of important display information,
That is, it is assigned to the elevator No. B EB displaying the car position. However, it often happens at times of congestion that the situation changes from moment to moment, especially when the passengers boarding from the lobby floor or the restaurant floor call the car late and the other cars are selected due to the full capacity.

An example of selecting and displaying the service zone from the registration status of the car call will be described with reference to FIG. FIG. 9 shows A,
Units C and D are servicing 1, B1 and 4th floor, respectively, B
The figure shows the case where the UP hall call is generated on the dining room floor on the second floor while the car is running on the ninth floor. At this time, Unit A has 4,
The car calls on the 5th and 6th floors and the car calls on the 7th and 9th floors are registered in Unit C, and it has been decided to service the car calls. At this time, from the car call that has already been registered, the service zone for guidance display is displayed for Unit A at 4-6.
It is assumed that the floor and Unit C are on the 7th to 9th floors, and the guidance display device installed at the second floor landing has already displayed guidance. Since it is predicted that the dining room floor will be overcrowded at this time, the newly generated UP hall call on the second floor is assigned two units, A and C, which are displaying the guidance display. In addition, by setting the car call unregisterable range from the already registered car call to the floor street that has already been guided to the landing, and limiting the car call registration, the time required for one round of the elevator is shortened.

[0044]

According to the present invention, by restricting the number of elevators that perform guidance display in the hall, the passengers are guided to the service elevator in the hall, and each floor is provided on the floor. By providing only one guide display device that displays the car position among the plurality of guide display devices, the user can easily select the elevator. Also, at the time of hall call registration, by selecting the assigned elevator from the elevators that display guidance in the hall, a reliable guidance display can be obtained, and the user's distrust and frustration with the guidance display content can be reduced. You can
