Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a group management control device for elevators.

<Prior art> Elevator group management that performs elevator group management control in order to provide efficient elevator service by organically relating the movements of each elevator to each other in response to traffic demand using multiple elevators. Control device is in use.

In the conventional group management control system, the signaling devices are an arrival light that operates by decelerating the elevator, and a service warning light that indicates which elevator among multiple elevators will respond to a call in the hall and service that floor. is provided.

With such elevator management systems, hall users can know which elevator will respond to a hall call. However, you will know when the elevator will arrive because the arrival light will turn on just before the elevator arrives. Generally, group management systems that have arrival forecast lights and service forecast lights do not include position indicator lights.

This is because, in the case of group control, elevators running near the called floor do not necessarily stop, so displaying the elevator location may cause confusion or discomfort to hall users. This is because it may cause.

Therefore, although hall users can know which elevator will respond to a call, they are not sure where the elevator is traveling, cannot predict the time it will take to arrive, and are forced to wait. There was a problem that the longer the time, the more irritated the user felt.

In an attempt to solve this problem,
No. 45469 proposes an elevator signaling device. In this proposed method, an elevator assigned to answer a hall call informs the hall users of the floor or elevator location to be stopped by providing service until the hall call is answered. It's getting old.
Hall users can know the number of times the elevator will stop before arriving and the location.
It is possible to estimate when the elevator will arrive.

<Problems to be solved by the invention> The inventors conducted and analyzed the awareness of elevator users, and found that when they answered a call within 10 seconds after registering the call, they did not feel anxious, but the time it took to answer was The results showed that users felt irritated when the waiting time exceeded 15 seconds.

The results of this awareness survey show that if the waiting time for a response to a hall call is less than 10 seconds, there is no need to display the elevator operating status to hall users until they respond to the hall call. It is determined that there is no. In this case, displaying the operating status of the elevator is difficult considering the power consumption of the display device and its image as a group management system.
It's unnecessary and wasteful.

This invention was made in view of the current state of the elevator signaling system proposed above, and its purpose is to provide a response time to a hall call within a preset predetermined time without spoiling the image of the group management system. To provide a group management control device for elevators, which allows users of a hall to know the operating status of the elevator to which they are assigned, when the number of elevators exceeds the limit.

<Means for Solving the Problems> The present invention includes an arrival forecasting device that allocates elevators that respond to hall calls and predicts the arrival of the allocated elevators, and a display device that displays the car position of the allocated elevator. is provided.
The present invention is provided with arithmetic processing means that calculates, when an elevator that responds to a hall call is assigned, a time period until the assigned elevator responds to the hall call. Further, the present invention is provided with a comparing means that compares the time calculated by the arithmetic processing means with a preset reference time, and sends out an output signal when the calculated time exceeds the reference time.

On the other hand, display means is provided, and when the output signal is sent from the comparison means, the display device is displayed by the display means.

<Operation> In the present invention, when a hall call is registered, the predicted response time of the elevator to respond to the hall call is calculated and output by the calculation processing means. On the other hand, the output of the arithmetic processing means is input to the comparison means, and the comparison means compares a preset reference time with the output of the arithmetic processing means.

The comparison means generates an output signal when the output of the arithmetic processing means exceeds the reference time, and the operation status of the elevator is displayed on the display device to the users of the hall by this output signal.

In this way, only when the response time to a hall call exceeds the standard time, the operating position of the elevator is displayed to the hall users, which reduces the power consumption of the display device and reduces the image of the group management system. However, an elevator group management control device is provided.

<Example> The present invention will be described below in detail based on an example using the drawings.

The figure shows the configuration of the main part of the present invention, and in the embodiment, only the elevator No. A is shown, and the service floors are the 1st to 10th floors.

Between the DC power terminals P and N, there is a slider F that moves in synchronization with the elevator and scales the movement of the elevator, a fixed contact 10S, an elevator position indicator light 10A10, a descending assignment contact 10DA ₁ , and a reference crossing contact T10DA. connected in series.

The number 10 in each code indicates that it is for the 10th floor, and the codes described below also indicate that it is for the 1st to 9th floors, respectively.

The fixed contact 10S is configured to be able to contact and slide on the slider F. The descending assignment contact _10DA1 is a contact that turns ON when a hall call in the descending direction occurs and machine A is assigned to this call. Further, the reference crossing contact T10DA is a contact that becomes ON when the time to respond to a hall call in the downward direction exceeds the reference time.

The fixed contacts 9S to 1S can contact the slider F,
It is arranged in line with the fixed contact 10S. Each of the fixed contacts 9S to 1S has a position indicator light 1.
One end of each of the position indicator lights 0A9 to 10A1 is connected, and the other end of each position indicator light is connected to a connection point between the position indicator light 10A10 and the downward allocation contact _10DA1 .

A position indicator light 9A is connected between the connection point between the fixed contact 10S and the position indicator light 10A10 and the current power supply terminal N.
10. Ascent assignment contact 9UA ₁ and reference crossing contact T9
UA is connected.

The upward assignment contact _9UA1 is a contact that turns ON when a hall call in the upward direction occurs and machine A is assigned to this call. In addition, the reference crossing point T
9UA is a contact that turns ON when the time to respond to a hall call in the upward direction exceeds the reference time.

Between the connection point between the fixed contact 9S and the position indicator light 10A9 and the DC power terminal N, a position indicator light 9A9
The descending allocation contact _9DA1 and the reference crossing contact T9DA are connected in series.

A position indicator light 9A2 is connected between the connection point between the fixed contact 2S and the position indicator light 10A2 and the connection point between the position indicator light 9A10 and the ascending assignment contact _9UA1 .
The connection point between the position indicator light 9A10 and the upward assignment contact 9UA ₁ , and the connection point between the position indicator light 9A9 and the downward assignment contact 9
The connection points with DA ₁ are connected to each other.

A position indicator light 9A1 is connected between the connection point between the fixed contact 1S and the position indicator light 10A1, and the connection point between the position indicator light 9A9 and the descending allocation contact _9DA1 .

Although the position indicator lights 9A3 to 9A8 are omitted in the figure, they are connected in the same way.

At the DC power supply terminal P, descending assignment contact 10DA _2,9
One end of DA ₂ . . . and upwardly assigned contacts 9UA ₂ , 8UA ₂ . The output terminal of the comparison means T is connected to the DC power supply terminal N.

The comparison means T compares the calculation time of the calculation processing means for calculating the time until responding to the hall call with a preset reference time, and sends out an output signal when the calculation time exceeds the reference time.

For example, when a descending call occurs to the elevator on the 9th floor and machine A is assigned, descending assignment contact 9
DA ₁ turns ON. At the same time, the descending assignment contact 9DA ₂ connected to the input terminal of the comparison means T turns ON, and the comparison means T calculates the calculation time calculated by the calculation processing means until the car No. A responds to the hall call.
A comparison is made with a preset reference time of, for example, 10 seconds.

Only when the computation time exceeds the reference time by comparison using the comparison means T, the reference crossing point T9DA is determined.
It turns ON and the display device displays the information.

For example, if machine A is waiting on the first floor, machine A starts to rise, and the slider F changes its contact position from fixed contact 1S to 2S, 3S, and so on. When the slider F is in contact with the fixed contact 1S, the DC power terminal P, the slider F, the fixed contact 1S,
A closed circuit is formed by the position indicator light 9A1, the lower assignment contact 9DA ₁ , the reference crossing contact T9DA, and the DC power supply terminal N. Therefore, the position indicator light 9A1 of the hall on the 9th floor
lights up, indicating that the elevator you should arrive at is located on the first floor.

As the elevator moves, the slider F comes into contact with the fixed contacts 2S, 3S, . . . , and at the same time, the position indicator lights 9A2, 9A3, . . . turn on, and the position of the elevator is displayed.

If the response time of the elevator does not exceed the reference time, the reference crossing point T9DA will not be turned ON, so the position indicator light will not light up.

In this way, only when the response time to a hall call is predicted to exceed the reference time, an elevator position indicator is displayed to the hall patrons;
There is no unnecessary display on the display device, power consumption is reduced, and appropriate control is performed without spoiling the image of the group management system.

<Effects of the Invention> As described in detail above, according to the present invention, the operating position of the elevator is displayed on the display device only when the response time of the elevator exceeds a predetermined reference time. It becomes possible to provide an elevator group management control device that enables smooth use of elevators, improves services, reduces power consumption of display devices, and does not damage the image of the group management control method. .
