Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waiting time display device for a group control elevator for informing a waiting passenger at a landing time of arrival of an elevator car.

[0002]

2. Description of the Related Art Generally, when using an elevator, a call button at a hall is pushed to wait for the arrival of the elevator. Normally, in the group management elevator system, the generated hall call is assigned to an optimum elevator selected from a plurality of elevators and made to respond to it. At this time, in the elevator system of the first type, a reservation display is performed in order to notify the waiting information at the hall in advance of the allocation information.

In the second type elevator system, reservation display is not performed, but arrival forecast display for notifying arrival at the time when deceleration is started is displayed in response to an elevator hall call.

Normally, reservation display is performed only by the highest class system, and most of the systems do not perform reservation display. In this case, passengers at the hall cannot know which unit will respond until the elevator arrives after pressing the call button, and it does not consider how long to wait, which causes frustration. .

As a means for solving this, a system for displaying the waiting time at the hall has been proposed, but this function is self-confidence, the waiting time is displayed for each car, and it is premised that it has a reservation display function. Has become.

In the system having the reservation display function,
In order to inform the allocation, the answering machine is decided earlier than when the call occurs. In addition, as a general rule, we refrain from responding to changes in the system status in order to avoid the movement of waiting passengers due to changes in forecasts, so we are slightly out of optimal control, and as a result there is a drop in service in terms of waiting time. You are inviting. As a countermeasure against this, a proposal has been made regarding a control technique for delaying the reservation display by suspending the allocation for a while when there are a plurality of optimal machines corresponding to the allocation evaluation.

In this case, while the forecast is being sent, the system is in the same state as that of the system without the forecast, including the above-mentioned problems. This problem, that is, it is necessary to speed up the determination of the optimum number of units to shorten the period, which goes against the intention of reservation reservation, which is to improve the reservation-like intermediate ratio and improve the overall service. Further, in this class of system, a method of displaying waiting time as described above to alleviate the annoyance of waiting passengers is also taken.

FIG. 3 is a schematic view of an elevator for explaining this. The hall call registration push buttons (hall call registration push lamps) 1a to 1g, the group management control device 2, and the hall call allocation control section 2a. The waiting time calculation unit 2b, the elevator control units 3a and 3b, the waiting time display units 4a to 4g, the arrival forecast lanterns 5a to 5g, and the transmission line 7.

In this conventional example, waiting time display units 4a to 4g are installed for each car at the hall, and the hall call allocation control unit 2a is provided.
When the hall is assigned by, the waiting time until the car responds to the call is displayed in units of cars.

[0010]

In the configuration of FIG. 3, since the waiting time display portions 4a to 4g are provided for each car and the waiting time display is carried out for each car, the waiting time display control system alone is extremely costly. It has become a thing. Therefore, it is rare that the waiting time display is actually applied to all floors.

Therefore, an object of the present invention is to solve such a problem, and it is possible to display the waiting time of an elevator at low cost regardless of the presence or absence of the reservation display function. To provide a device.

[0012]

In order to achieve the above-mentioned object, the invention according to claim 1 is a group supervision control elevator for controlling the elevators of a plurality of elevators to efficiently respond to a plurality of calls. When a call or a landing descent call is registered, a waiting time until an elevator car assigned to each landing call arrives is calculated in correspondence with the ascending call or descent call,
At least one of waiting time display means dedicated to ascending call and waiting time display means dedicated to descending call, which are provided in each hall and are common to all units, is provided, and the waiting time calculated by the calculating means is used for the ascending or descending call. It is a waiting time display device for an elevator characterized in that it is displayed on a waiting time display means corresponding to.

[0013]

According to the invention according to claim 1, when a hall call is registered, a waiting time until the hall call is answered is calculated, and each hall is used as a waiting time for the hall call to rise or descend. The waiting time display means dedicated to the ascending call and the waiting time display means dedicated to the descending call which are common to all the vehicles are displayed. As a result, the waiting time can be displayed at the landing at a low cost regardless of the presence or absence of the reservation display function, and the service to the user can be improved.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a first embodiment of the present invention, which is intended for a system without an allocation forecast display function, but is not limited to this. In the present embodiment, the waiting time display portions 4a ... 4e to 4g of the hall are provided not for each unit but for the ascending call and the descending call commonly to each hall. In addition, the waiting time display section 4a of the hall
A waiting time display control unit 2c for displaying the waiting time calculated by the waiting time calculation unit 2b as a waiting time for a landing ascent or descent is provided at ˜4g.

The push call buttons 1a to 1g for hall call registration, which are arranged at the halls on each floor, are sent via the transmission line 7 to the group management control device 2 installed in the elevator machine room. This signal is input to the hall call assignment control unit 2a in the group management control device 2, and the hall call is assigned here. Then, the waiting time calculation unit 2b calculates the waiting time until the elevator car of the assigned car arrives by the hall call assignment control unit 2a. The waiting time calculated by the waiting time calculation unit 2b is input to the display control unit 2c, and a display control signal is output to the waiting time display units 4a to 4g installed at the landing of the corresponding floor.

Each elevator control unit 3 in the group management system
The state signals a, 3b ... Are input to each unit of the group management control device 2. The control output of the waiting time display control unit 2c is the waiting time display units 4a, ... 4 installed at each landing on each floor.
e, 4f, 4g. Arrival forecast lanterns 5a, ... 5 installed at each floor at each landing
e, 5f, 5g, 6a, ... 6e, 6f, 6g are controlled by each elevator control device.

According to the embodiment configured as described above,
The following effects can be obtained. Now, a case where the user operates, for example, an ascending call on the fifth floor will be described. The call signal is input to the call registration unit (not shown) of the group supervisory control device 2 via the transmission path 7 to perform the registration process and turn on the response lamp at the hall.

The call registered by the call registration unit is input to the allocation control unit 2a. This system does not support reservation display, so at this point lantern 5a ~
5g and 6a-6g are not lit.

The assignment control unit 2a assigns a call by selecting an optimal number from the numbers in the group. The waiting time calculation unit 2b calculates the time required to respond to the assigned machine call based on the result of the assignment and the status signal of each machine. The data of the calculated result is input to the waiting time display control unit 2c, and the current waiting time is displayed on the rising direction side of the waiting time display unit 4e that responded to the ascending call on the fifth floor.

As a method of displaying the waiting time, for example, as shown in FIG. 2, the waiting time display sections 4a to 4 are displayed according to the waiting time.
The lighting area of g is changed. That is,
FIG. 2A shows a case where the lighting areas of the waiting time display portions 4a to 4g are small, the assigned elevator is still far away, and the waiting time is large. 2 (b) and 2 (c) are shown in FIG. 2 (a).
The lighting area of the waiting time display portions 4a to 4g is larger than that of the above state, indicating that the elevator is approaching the corresponding landing. FIG. 2D shows the waiting time display unit 4 at the end.
In the state where all areas a to 4g are blinking, it shows that the waiting time for the hall is zero, that is, the elevator car has arrived at the corresponding hall.

By doing so, the passenger waiting at the hall does not know the answering machine, but can know how long to wait. Finally, when the elevator starts decelerating in response to a call, the lantern of the No. 1 ascending call response on the 5th floor blinks to guide the waiting passengers. Here, if an elevator with better conditions occurs in the middle of Unit 1 response,
The assignment control unit 2a reviews the call assignment and changes the assignment to another car. The result is also the waiting time calculation unit 2
Then, the waiting time display section 4e is similarly displayed. Similarly for down calls, only waiting time is displayed with no assigned number displayed.

According to the above-described embodiment, the waiting time can be displayed even in the case of the system without the allocation forecast, so that the annoyance of waiting customers can be eliminated. The embodiment described above can realize the waiting time display at an extremely low cost even when used in the system with the allocation forecast.

In the above-mentioned embodiment, the display of the waiting time is shown in three stages, but it is easy to set it in multiple stages.
Further, the applied group management elevator system was also a system without forecast display, but the same effect can be obtained even if it is used with a forecast display or with a forecast hold function.
