[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator landing notification device.

[0002]

2. Description of the Related Art In an elevator landing notifying device in which a landing assignment number forecast and a car arrival forecast are notified by an indicator lamp (hole lantern), generally,
When a group management control of multiple elevators is performed, a forecast display of the landing call numbering unit and a landing display when the car arrives, regardless of the elevator control method, will be notified to the landing waiters. ing. The shape of a conventional hall lantern used in such an elevator landing notification device is as follows: (1) An upside lantern 1U and a downside lantern 1D shown in (a) and (b) of FIG. (2) 2U, 2D obtained by dividing each lantern into a plurality of blocks as shown in (a) and (b) of FIG.

In the above (1), the turning on / off control is performed at the timing shown in FIG. 7, and in the above (2), the turning on / off control is performed at the timing shown in FIG.
Light-off control is performed.

For example, in the above (1), when the upward lantern 1U is lit for the allocation forecast display,
The lighting starts at timing A, starts blinking at timing E when the assigned car arrives at the hall floor, and generally, at timing F when the landing and opening the door, and closing the door after the passenger gets on and off. It turns off the light.

In the above (2), when the block a of the upward lantern 2U is turned on for the forecast display, the lighting is started at timing A, and the assigned car arrives at the hall floor. . For example, the block b is turned on at the timing B 15 seconds before, and the timing C at 10 seconds before.
, The block c is turned on, and the block d is turned on at a timing D 5 seconds before. Then, at the arrival landing timing E, all the blocks start blinking, and as in the above (1), the doors are opened, and the lights are turned off at the timing F when the doors are closed after the passengers get on and off. It changes as shown in a) to (e).

[0006]

However, in such a conventional elevator landing notification device,

(1) Although it is possible to know the car that responds to the generated hall call, it is not possible to know how long it will take for the elevator of the car to arrive from the display.

(2) In particular, when the waiting time is long, such as when the demand for elevators increases, it takes a long time after the forecast display is performed until the next waiting time display block is turned on.

For example, when the waiting time for arrival is 1 minute or more, the section of AB in FIG.
It seems that the elevator is stopped somewhere, and in either case, there was a problem that the passengers at the landing were irritated.

[0010] The present invention has been made in view of such a conventional problem, and informs a waiting passenger of a change of an estimated waiting time by increasing or decreasing the area of a lighting portion of a hall lantern, thereby causing the waiting passenger to be irritated. It is an object of the present invention to provide an elevator hall notification device capable of alleviating the load. [Configuration of the Invention]

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an elevator user who is informed of an elevator which responds to a hall call in advance, and a user of the elevator which responds to the hall call. In the elevator landing notification device in which an indicator light for notifying arrival is provided at each landing, and the indicator light is divided into a plurality of blocks that can be individually turned on and off, the lighting timing of each of the plurality of blocks is determined by the block. A first indicator control means for controlling each block in accordance with a predetermined predicted waiting time and sequentially lighting these blocks; and averaging the lighting timing of each of the plurality of blocks based on an initial value of the predicted waiting time. Second indicator light control means for sequentially lighting the light at the averaged lighting timing; and controlling the first indicator light in accordance with the magnitude of the initial value of the estimated waiting time. And a display switching means for selectively switching between a step and the second indicator light control means, wherein the display switching means controls the second indicator light control means when an initial value of the estimated waiting time is equal to or longer than a predetermined time. It is designed to be switched.

[0012]

With such a configuration, when the initial value of the predicted waiting time for the hall call is small, each block of the indicator lamp is controlled at a predetermined normal lighting interval, and the initial value of the predicted waiting time is large. In this case, the lighting intervals of each block of the indicator light are averaged as a whole.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which a plurality of elevators, the operation of which is controlled by group control, moves up and down 10 floors of a building to provide services.

Therefore, each elevator is totally controlled by the group management control device, and it is determined which car is to respond to the hall call generated at an arbitrary floor from the result of the arrival prediction calculation of each car, Assigns the most suitable car to its hall call, and each car has a single control unit that responds to your car call, and accelerates, decelerates, arrives at the destination floor, etc. For the group management control, various methods have been conventionally proposed, and any of them can be used.

A feature of the embodiment of the present invention is that, when an actual ride occurs, if any car is assigned to the hall call, the assigned car arrives at the hall call registration floor. How to control the lighting of the indicator lamp depends on the length of the estimated arrival time that is predicted to be required until the start.

FIG. 1 shows an embodiment of a hall notifying device used for such lighting control of an indicator lamp. The hall call buttons 11, 12,..., 1a installed at each hall and an elevator at each hall. Indicator lights (hole lanterns) 21, 22,..., 2a installed near each car are provided.

Each of the hall call buttons 11, 12,...
An input control unit 1b that inputs a hall call signal when any one of the hall calls 1a is pressed, and a registered hall call,
A data storage unit 1c which stores, as a table, car position information of each car, car call state information, and hall call state information that may be occurring on other floors.

Further, a predicted arrival time of each car is calculated based on the data in the data storage section 1c to determine which car elevator is optimally assigned to the hall call signal from the input control section 1b. A waiting time calculating unit 1d for determining an assigned car by judging according to the magnitude, and further outputting the predicted waiting time; and a waiting time calculating unit 1d
Is controlled based on the predicted waiting time obtained in (1), the number of lighting blocks of the hall call occurrence floor indicator light (for example, if the hall call occurrence floor is the fourth floor, the indicator light 24 on the fourth floor), and the light-off control is performed. First indicator light controller 1f and second indicator light controller 1g
It has. Each of the indicator lamps 21, 22,... 2a is divided into a plurality of blocks, as shown in FIG. 6, both the up-side display unit 2U and the down-side display unit 2D. The blocks a, b, c, and d of each stage are individually turned on and off by the first indicator light controller 1f or the second indicator light controller 1g. Next, the operation of the elevator landing notification device having the above configuration will be described.

As shown in the timing chart of FIG. 8 and the flowchart of FIG. 2, when a hall call occurs on a certain floor, it is determined whether the own car is an elevator responding to the hall call, and the self car is assigned as a responding car. If it has been received (step S1), then the predicted arrival time for the hall call (this is the estimated waiting time for the user at the hall call floor) is calculated (step S2). This waiting time calculation method is a generally well-known method,
Calculated based on the data stored in the data storage unit 1c, such as the floor call floor to be responded, the car position, direction, speed, and predicted car call of the own car. Next, in step S3, the process is distributed to the next process according to the magnitude of the estimated waiting time obtained in step S2. In this embodiment, since the indicator light is divided into four blocks, the predicted waiting time T is: (1) T> 15 seconds (2) 15 seconds ≧ T> 10 seconds (3) 10 seconds ≧ T> 5 seconds ( 4) Control is performed in four cases of 5 seconds ≧ T. Of course, in this control, if the block is divided into four or more blocks, control at a stage corresponding to the number of divisions is performed.

If T exceeds 15 seconds, step S4
Turns on the part a and turns off the parts b and c. That is, in FIG. 8, only the portion a is lit as in the period from the hall call occurrence point A to the point B. T is 15
In the case of less than second and up to 10 seconds (2), that is, in the period from point B to point C in FIG.
The part is turned on, and the part c is turned off. Further, when T is 10 seconds or less, that is, during the period from point C to point D in FIG. 8, the portions a, b, and c are turned on, the portion d is turned off, and when T is 5 seconds or less (4 8), that is, in the period from the point D to the point E in FIG. 8, all the portions a, b, c, and d are turned on. In this manner, the waiting time is increased or decreased by increasing or decreasing the number of lighting blocks of the blocks a, b, c, and d of the indicator light in accordance with the estimated waiting time required to respond to the hall call in response to the hall call. Let the customer know.

Subsequently, in step S8, it is determined whether or not the car has landed on that floor.
After landing in steps 9 to 10, the door is opened, and then the user finishes getting on and off, and the indicator light is flashed until the door closes (in FIG. 8, the period from point E to point F). Then, after landing, when the passenger gets on and off and the door is closed, the lighting of the indicator lamp is reset as in step S11. If the own car is not assigned to the hall call, in step S12, the display lamp of the own car is turned off, and a flash reset is commanded. The above is the operation performed by the first indicator light control unit 1f shown in FIG. 1, and this is a diversion of a conventional technique.

On the other hand, the second indicator light control 1g in FIG.
As shown in the timing chart of FIG. 8 and the flowchart of FIG. 3, when the hall call occurs on a certain floor,
It is determined whether or not the own car is an elevator responding to the hall call, and if the own car is assigned as the answering car (step S1), then the estimated arrival time for the hall call (for the user of the hall call floor) Calculates the estimated waiting time) (step S2). This waiting time calculation method uses a method well known in the art to store the data stored in the data storage unit 1c, such as the hall floor to be responded, the car position, direction, speed, and predicted car call of the own car. It is calculated on the basis.

Next, in step S30, step S
The lighting timing of each indicator lamp block is determined by the following equation based on the initial value of the estimated waiting time obtained in step 2 and the number of divided indicator lamp blocks. Here, x in the expression (1) is an example in the case where the time during which the last block d is turned on is fixed between points D and E in FIG. Is calculated.

In this embodiment, the indicator light is divided into four parts.
Since it is a block, if it is substituted into equation (1), the block switching interval is (initial value of predicted waiting time−5 seconds)
/ (4-1), for example, if the predicted waiting time is 1 minute, the value is 18 seconds, and the part a is turned on in step S4 because the assignment occurs and the step S5 is immediately executed. The part b lights up after 18 seconds of lighting of the part a.
The lighting of the portion c in step S6 is caused by the lighting of the portion b 18
Seconds later, the lighting of the portion d in step S7 is 18 seconds after the lighting of the portion c. That is, points A to B and B in FIG.
This means that point C and points C to D are all divided in equal time.

Subsequently, in step S8, it is determined whether or not the car has landed on that floor. If so, the doors are opened after landing in steps S9 to S10, and then the user gets on and off. Then, the indicator lamp is flickered until the door is closed (the period from point E to point F in FIG. 8). Then, after landing, when the passenger gets on and off and the door is closed, the lighting of the indicator lamp is reset as in step S11. If the own car is not assigned to the hall call, in step S12, the display lamp of the own car is turned off, and a flash reset is commanded. Here, a comparison is made between two cases where the predicted waiting time is 1 minute and 30 seconds. (1) When the predicted waiting time is 1 minute (1-1) The first indicator light control unit 1f In FIG. Points A to B are 45 seconds, points B to C are 5 seconds,
Points C to D are 5 seconds, and points D to E are 5 seconds. (1-2) Second Indicator Light Control Unit 1g (a) In the Case of Equation (1) In FIG. 8, points A to B are 18 seconds, and points B to C are 18 seconds.
Seconds, points C to D are 18 seconds, and points D to E are 5 seconds. (B), Equation (2) In FIG. 8, points A to B are 15 seconds, and points B to C are 15 seconds.
Seconds, points C to D are 15 seconds, and points D to E are 15 seconds. (2) In the case of a predicted waiting time of 30 seconds (2-1) First indicator light control unit 1f In FIG. 8, points A to B are 15 seconds, points B to C are 5 seconds,
Points C to D are 5 seconds, and points D to E are 5 seconds. (2-2) Second indicator light control unit 1g (a), in the case of equation (1) In FIG. 8, points A to B are 8 seconds, points B to C are 8 seconds, C
Points to D are 8 seconds, and points D to E are 5 seconds. (B) In the case of equation (2) In FIG. 8, points A to B are 7.5 seconds, and points B to C are 7.
5 seconds, points C to D are 7.5 seconds, and points D to E are 7.5 seconds.

Therefore, as described above, these two indicator light control units have advantages and disadvantages, respectively. The first indicator light control unit 1f is effective when the estimated waiting time is short. However, if it is long, it takes time from the lighting of the a block to the lighting of the next b block, and the second indicator light controller 1g of the latter is effective when the predicted waiting time is long. However, when the time is short, each block display interval time is different every time, so that it is difficult to predict the arrival time from the viewpoint of the waiter.

For this reason, the display switching unit 1e shown in FIG. 1 receives the estimated waiting time from the waiting time calculation unit 1d, and switches the indicator light control unit according to the length thereof, and only the merit part of each indicator light control unit. Pull out.

For example, when the estimated waiting time is one minute or more, the second indicator light controller 1g controls the arrival notification lights 21 to 2a.
If less than one minute, the first indicator light control unit 1
f, the arrival notification lights 21 to 2a are controlled.

In this way, when the elevator of a certain car responds to the hall call and travels to the hall call registration floor after being assigned, the indicator lamp block is performed according to the length of time expected to arrive at the floor. By increasing or decreasing the number of users, the waiting time is notified to the user, and the annoyance of the user can be suppressed. When responding to a car call,
As before, the indicator light is displayed blinking at the time of landing.

In the above embodiment, the indicator lamps 21 and
Although a triangular object is used for 2,..., 2a, the shape of this indicator light is not particularly limited, and the indicator lamp is formed into a columnar shape as shown in FIG. , C,
The display may be divided by d.

[0032]

As described above, according to the present invention, when the initial value of the estimated waiting time for a hall call is small, each block of the indicator lamp is controlled at a predetermined normal lighting interval, and the initial value of the estimated waiting time is reduced. If the value is large, the lighting intervals of the blocks of the indicator lamps are averaged as a whole, so that accurate notification without discomfort can be provided, and an elevator more suited to user needs can be provided.
