Description

Description: [Industrial field of application] The present invention relates to an elevator display device.

[Conventional technology]

As a conventional method of displaying the driving direction at the elevator hall, there is an indicator method that indicates the car position and the driving direction,
There is a hall lantern method that indicates the service direction upon arrival. The hall lantern method may have a function of indicating the direction of service in advance after the hall call is registered.

However, in any case, how to display when the elevator answers the last call to be serviced, which is not a landing call, is a difficult problem. Normally, it seems that you don't need to display either direction because you are just waiting on that floor, but the following will occur.
That is, when the passenger who wants to board arrives at the landing when the last passenger gets off after opening the door, he / she is confused because he does not know in which direction the elevator goes. Also, if there are passengers who want to go in different directions almost at the same time, the direction will be the customer who pressed the car destination button a little earlier, so the person who pressed later will get off immediately or the opposite direction. You have to stay on until the end of the service and then press the destination button again.

Therefore, in the hall lantern system indicating the service direction, it is usual to turn on the direction determined by the floor correspondence. Normally, the lower floors including the first floor show the upper side, the uppermost floor shows the lower side, and the other floors show the same direction as the traveling direction until now.

However, once the hall lantern is turned on, even if there is a passenger who wants to go in the direction opposite to that displayed, it cannot be said that the hall lantern will be reversed immediately. This is because there may be passengers who have already trusted the hall lantern and boarded.

On the other hand, Japanese Laid-Open Patent Publication No. 54-31150 discloses a method of setting the direction of a hall call or the direction toward a floor with a large amount of traffic which is set in advance.

However, when there is no hall call, it is the same as the above-mentioned "direction determined by floor correspondence", and the effect was small.

[Problems to be Solved by the Invention]

Since the conventional elevator driving device is configured as described above, if there is a passenger who wants to go in the direction opposite to the direction in which the hall lantern is lit at the final elevator floor,
Even if you can service immediately, you have to close the door just in case and confirm that there is no car call in the direction in which the hall lantern is lit, then open the door and service, waiting for you at the hall Was frustrated and there was a problem in overall efficiency.

The present invention has been made to solve the above problems, and it is possible to determine the lighting direction of the hall lantern to the direction that passengers in the hall want to go, and to reduce the chances of occurrence of the above events as much as possible. The purpose is to obtain a display device for an elevator.

[Means for Solving the Problems]

The display device of the elevator according to the present invention, when the elevator stops for the last call to be serviced, which is not a landing call, determines the high direction of establishment of passengers on the floor to be stopped to the direction that was registered until recently. And a means for lighting a hall lantern or a direction light in that direction.

[Action]

In the present invention, the hall lantern is turned on by determining the direction of high probability of passengers on the floor to stop to the direction that has been registered until recently, and turning on the hall lantern or direction light in that direction. Passengers who want to go in the opposite direction are less likely to be in the hall.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a block diagram showing an entire display device for an elevator according to an embodiment of the present invention. In FIG. 1, (1) is an elevator car, (2) is a hoist, and (3) is a controller.
Central processing unit (hereinafter referred to as CPU) that performs operation control processing (3
1) and read-only memory (hereinafter referred to as ROM) (32)
And a readable / writable memory (hereinafter referred to as RAM) (33) and an input / output interface (34). (1F) ~ (5F)
Are elevator halls on the 1st to 5th floors, and (40) is a destination button provided in the car, which actually consists of 5 buttons on the 1st to 5th floors. (41) to (45) are the 1st to 5th floor hall buttons provided on the elevator halls (1F) to (5F) on the 1st to 5th floors, respectively. 42) ~
(44) consists of two buttons in both up and down directions, and (45) consists only of downward row buttons. Similarly, (51) to (55) are hall lanterns on the 1st to 5th floors, and the same number of hall buttons is installed depending on the floor.

Further, FIG. 2 is a flow chart of a program stored in the ROM (32) and calculated by the CPU (31), and FIG. 3 is a flow chart showing details of the floor-specific traffic learning function (S2) of FIG. Fig. 4 also shows a flow chart showing the details of the direction setting function (S3), respectively. The functions of these programs are as follows: When the elevator stops for the last call to be serviced, which is not a landing call, It learns the high direction of the passengers heading for and lights the hall lantern in that direction.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. Now, in FIG. 1, the upward button is pushed in the hall buttons (43) on the third floor, and the car (1) approaches the third floor, and is about to stop at the upper call on the third floor. At this time, in FIG. 2, various signals are input through the input / output interface (34) in step S1, which includes the position, direction, state of the elevator, car call, and hall call. These pieces of information are stored in the RAM (33).

Next, proceeding to step S2, if there is now a hall call only on the third floor, steps S21 to S22, S24, S in FIG.
In step S26, N = 3 is set, and the process proceeds from step S27 to step S22 again. Here, since there is an upward call for the third floor, UPCALL (3) = 1 in step S23. Others have no call and proceed to "end". Note that here UPCALL
(2) to (4) are initially set to "0". It has no significant meaning, so it is not shown in the figure.

A detailed view from step S3 to step S31 in FIG.
Proceed to. Since it is about to stop, step S32
And go to the floor (3rd floor) where you are about to stop (upward)
Because there is a landing call, it becomes "Yes" and the direction remains unchanged. If there is only a hall call on this floor that is the opposite of the current direction, steps S32 to S33 to S3
Go to 5 and reverse the direction.

In any case, the process proceeds to step S4 in FIG. 2 and the hall lantern (53) on the third floor is turned on through the input / output interface (34). When calling up the hall, it means going up.

Now, let's assume that car (1) is about to stop after answering the final car call on the 3rd floor. In FIG. 4, the process proceeds from step S31 to S32, all of the steps S32 to S34 are “No”, and the process proceeds to step S36. Since the floor to be stopped is 3, the process proceeds to step S37, and since UPCALL (3) = 1 here, the direction is set to the upward direction in step S38.

If a downward call occurs after the first-mentioned upward call on the third floor, the process proceeds to step S25 in step S24.
UPCALL (3) = 0 and the direction is downward. That is,
The direction is determined by which call was registered until the last call stop. It seems like a simple decision, but it works especially well for systems served by multiple elevators. That is, in the case where passengers are generated to the extent that one elevator cannot get through, the second elevator arriving can efficiently respond by displaying it in the direction of the call registered before that.

〔The invention's effect〕

As described above, according to the present invention, when the elevator stops for the last call to be serviced, which is not a landing call, the highly established direction toward which passengers on the floor to stop is registered until recently. Since it was decided to turn on the hall lantern in that direction, it is not necessary to obtain statistical results of past traffic conditions such as the number of calls by each direction and the number of passengers, and prediction based on the statistical results is performed. There is no need, and therefore a simplified configuration that omits the configuration determines the likely direction of passengers on the floor to stop when the elevator stops for the last call that should be non-landing service. This reduces the possibility that passengers who want to go in the direction opposite to the lighting direction of the hall lantern will be in the hall, preventing frustration of passengers and reduction in overall operating efficiency. Door can be.
