Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a device that is installed in an elevator car or a landing and displays the situation in which the car approaches the landing. .

Conventional technology] Passengers who were previously waiting for their cars to arrive at platform 9.

The robot learns the location and driving direction of the car based on the movement of the car position indicator, determines which car will arrive first (on the floor it is on), and waits in front of the door of that car.

However, if there is a lot of white sand in which the car is installed, it becomes extremely difficult to find the desired car based on the ever-changing car position and driving direction.
As shown in Publication No. 0266, the time required for a car responding to a landing call to arrive at the landing is calculated,
This will be displayed at the landing area for each car as a predicted waiting time.

A method has been proposed to eliminate the anxiety and impatience of waiting customers by informing them how long they will have to wait for the basket to arrive.

However, this method of displaying the waiting time numerically (hereinafter referred to as the numerical display method) is

This has the advantage that it is easy for first-time customers to understand that the displayed content means the waiting time, but on the other hand, if the predicted waiting time and the current displayed content differ This also had the problem of being easily noticeable and creating a sense of distrust and irritation among waiting customers.

! f, ta. In order to solve the problems of the above numerical display method, as shown in Japanese Patent Laid-Open No. 54-47261, a method (hereinafter referred to as A method (referred to as a single-figure display method) has also been proposed. but.

Since this graphical display method graphically guides the approach of the car, it is difficult for visitors using this elevator for the first time to understand what the above display means (in the end, the effect of the above display is not fully understood). There was a problem that it could not be fully demonstrated.

Therefore, in order to make it easy for even first-time users to understand the above display contents, and to avoid causing a sense of distrust or irritation when changing the display contents, we have divided the display into two display areas that do not overlap with each other. A display device is installed inside the car or at the landing, and as the car approaches the landing, the display area (lighted area) of the first display area is gradually decreased, and the display area (lighted area) of the second display area is decreased accordingly. It has been proposed to display the situation in which a car is approaching by gradually increasing the number of cars.This will be explained with reference to FIGS. 5 to 9.

Figure 5 is an overall configuration diagram to clearly show the configuration of the conventional example.
A is an approach situation calculation means that calculates and outputs the situation in which the cage approaches the landing, and B is a display device installed in the landing, with three display areas Bl that do not overlap with each other.

It has B2 and B3. C is a display that controls the lighting area of two display areas B1 and B2 of display B, respectively, and controls the display form of one display area B3? l
The i control means gradually decreases the lighting area of the first display area and gradually increases the lighting area of the second display area as the car approaches the landing area based on the output of the approach situation calculation means A;
At the same time, the lighting mode in the third display area is periodically changed.

Figure 6 rr! This shows the landing on the third floor of a six-story building with two elevators, and DI and B2 are the landing doors for Unit 1 and Unit 2, respectively.

H is the hall operation panel with an up button and a down button, N4
and B2 are the up hall lanterns of No. 1 and No. 2, respectively; Uplink waiting time indicator, same as LT1 and LT21d (downlink waiting time indicator that displays the approach situation when responding to a downlink call).

Figure 1 is a diagram showing details of the upstream waiting time indicator UTI for Unit 1 on the 3rd floor.
(6) to 00 respectively belong to the second display area B2, (H
A) to (IID) are indicator lights belonging to the third display area B3, respectively.

Figure 8 shows the display fljll M41 means 1 on the 3rd floor.
FIG. 2 is a circuit diagram showing a display control circuit C1u that controls an uplink waiting time indicator UTI for a car. Downward direction, other floors.

And other machines are also configured with similar circuits.

In the figure, Q3 is a well-known allocation device that allocates up calls and down calls registered by the hall operation panel H etc. to car No. 1 or Car No. 2 and outputs an allocation signal.

(N3u) becomes rHJ when the 1st car is assigned to the up call on the 3rd floor, and becomes rL when the 1st assigned car answers the above call.
This is the assignment signal for J. Cars No. 1 and No. 2 responded to the car call and the assigned landing call, respectively.
A well-known expected arrival time calculation device that calculates and outputs predicted values of the time it takes to arrive at each landing on the 6th floor to the 6th floor in the up direction and down direction (i.e., the expected arrival time) is used.
) is the expected arrival time signal for reaching the 3rd floor of Unit 1 (in 5 second increments)
It is. +141 is the car control device for Unit 1 that controls running operations such as determining the driving direction and running/stopping in order to respond to calls, as well as door opening/closing operations, etc. (+43u)
is output from the car control device (141) of the 1st car, and when the 1st car is assigned to the 3rd floor up call and arrives at the 3rd floor in the up direction in response, the arrival becomes rHJ only from the time of arrival until the completion of door opening. Right after that is the signal.

tzi+-(c) sets the output signals of two points to rHJ when the input signal at point X ≧ the human input signal at point Y, and otherwise sets the output signals at two points to rLJ, comparator, Tl ~ T

Id NOT gate.

FIG. 9 is a diagram showing changes in the display state of the uplink waiting time indicator UTI in FIG. 7. (However, the shaded area indicates the lighting state.) Next, the operation of this conventional example will be explained.

Assume that a waiting customer operates the up button on the third floor to register an up call, and the 9 allocation device u2 allocates car No. 1 to this call.

At this time, the 3rd floor ascending assignment signal of Unit 1 (I I 3u)
becomes rHJ. On the other hand, expected arrival time calculation device 0□□□
Therefore, the expected arrival time signal (1) of Unit 1 going up to the 3rd floor becomes 2.
Suppose that it is calculated and output as 5 seconds.

The outputs of comparison Masuda) to (c) are all rHJ, so the outputs of A N D gates C(II to (c) are also rH
J and the indicator lights (1) to (5) of the first display area B1
lights up.

On the other hand, the outputs of the NOT gates (50 to (55)) are all rLJ, so the output of the AND gate (force ~ +41 is also r
It becomes LJ, and the signal (+43u,) immediately after arrival is also "L"
Therefore, the output of the OR gate (49 to kl is also rLJ, and the indicator lights (61 to all) of the second display area B2 are turned off. The output of the gate (40 is [LJ, NO
The output of T gate (56) is [HJ, AND gate (42)
The output is rHJ, so the 9 indicator light (mouth A) and (+1
0) is turned off, and the indicator lamps (IIB) and (HD) are turned on. Conversely, the periodic pulse signal (A N between 50 and rHJO)
D gate (current output is [HJ, NOT game 1- <56
) output is "LJ, AI, ID gate (44 output is rLJ, so the 1 indicator lights (HA) and (NO) are lit and the indicator lights (IIB) and (IID) are off. Eventually, the 3rd Indicator light (HA) and (+10) of display area B3
The set of indicator lights (NB) and the set of indicator lights (11D) alternately turn on and off every 0.5 seconds. This flashing indicates that the sand in the hourglass is falling. This blinking continues while the assignment signal (++3u) is rHJO. In this way, the expected arrival time signal (1) becomes the constant value signal T5.
When the above value is taken, the state shown in (8) in FIG. 9 occurs.

(Note that the 9 indicator lights (IIAJ~(HD) blink).

Next, Unit 1 approaches the 3rd floor and the expected arrival time signal (1)
Suppose that the time period changes from 25 seconds to 20 seconds. At this time, 1(
=20 seconds J<T5 (=21 seconds), and only the output of comparator (2) becomes rHJ→rLJ.

The output of AND game 1-C becomes rHJ → "L".

The indicator light (5) in the first display area B1 goes out. At the same time, the output of the NOT gate (55) becomes rLJ→rHJ, so the output of the AND gate (to) becomes rLJ→“H”.

Then, the output of the OR gate (4) becomes rLJ→rHJ, and the indicator light (6) in the display area B2 lights up. Therefore, the display state of the display UTI at this time is (8) in FIG.
1 to (b).

Furthermore, as Unit 1 approaches the third floor, the expected arrival time signal (1
) changes sequentially from 20 seconds to 15 seconds, 10 seconds, and 5 seconds, the comparator 124. C7:◇, (The output of 221 changes from rHJ to rLJ in order, so the outputs of AND gates (2), (c), and 03 change to rH in order.
J → fLJ, AND gate (3η, 弼, 6 bells' outputs are rLJ → rHJ in order, OR gate f461. (47
), the output of the 14 barrels becomes rLJ→rHJff in order.

Therefore, the indicator light of the first display area B1 +4), f3
+, +21 go out at l1ii''t, and the indicator lights +7L, +81.
When the time changes to seconds, the display state of the 0 indicator UT+ is 9th.
It changes from (b) in the figure to (e), (d,), and (e) in order.

Then, when Unit 1 arrives at the 3rd floor in the upward direction, the 3rd floor upward call is canceled and the assignment signal (113u) changes to ``L'', and at the same time, the immediately after arrival signal (+43u) changes to ``■ ('', and the expected arrival time Signal (1) becomes 0 seconds.

Therefore, the outputs of AND gate e(11 to (42) are all r
LJ, so the indicator light (1) in the first display area B1
~(5) and indicator light of third display area B3 (+1h)
~(IID) all go out. Also, the signal immediately after arrival (14
Since 6- becomes rHJ, the outputs of the OR gates (49-(4ω) all become rHJ, so the indicator lights (6)-(II) of the first display area B12 are all lit. At this time, 9-display 1
The display state of the iUT1 changes from (e) to (f) in FIG.

Finally, when Unit 1 starts opening its doors on the 3rd floor, the signal (+43u) changes to rLJ immediately after arrival and the OR gate (I~
(Since all outputs of 4!l are rLJ, all indicator lights (61 to 00) in the second display area B2 are turned off and the state is the same as before the hall call was registered.In addition, the up-bound call on the third floor is the 1st unit (assigned to the 2nd unit (assignment signal (II; u) −r L J ), AND gate (lI) ~ (all outputs of 4 are 1x rLJ, so The display UTT of Unit 1 was turned off, so as not to confuse passengers waiting for Unit 2.

In this way, in the conventional example, when the expected arrival time signal (1) becomes smaller as the car approaches, the first display area B
The area where the indicator lamps of the second display area B2 are lit is reduced, and at the same time, the area where the indicator lamps of the second display area B2 are lit is increased from zero.

The approach status of the car is displayed in an hourglass-like display format, so that even first-time customers can understand the displayed content.

[Problem that the invention seeks to solve]

However, in the conventional example described above, when the expected arrival time at the time when a hall call is assigned is 25 seconds, the display starts from the state shown in FIG. 9(a), whereas the arrival at the time when a hall call is assigned If the expected time is 15 seconds, the 9th
The state of (C) in the figure, that is, the indicator light (+,) of the first display area B1, +21. (3) and second display area B
The process starts with indicator lights (6) and (7) of No. 2 on. Therefore, since the display starts with sand accumulated in the lower part of the hourglass, it gives waiting customers the false impression that they have already waited for the corresponding amount of time due to the association with the hourglass, and this creates a sense of impatience and suspiciousness. It is quite conceivable that there will be some customers waiting who feel emotional. In addition, in the above conventional example, the indicator light 1
The unit time is fixed at 5 seconds, and the maximum waiting time that can be displayed is 2.
5 seconds, so if the expected arrival time at the time the hall call is assigned is 40 seconds, the state in (a) in Figure 9 is 20 seconds.
The process lasts for a second (this means that the elapsed time during the process is unknown, which makes waiting customers feel impatient. In this way, in the above conventional example).

The problem was that it made waiting customers feel unnecessarily anxious and suspicious.

This invention was made in order to solve the above-mentioned problems, and in a device that guides the approaching situation of a car using a display device divided into two display areas, the meaning of the lighting area of these display areas is To provide a display device for an elevator that does not cause waiting customers to be misunderstood and does not make waiting customers feel unnecessarily anxious or suspicious.

[Means for Solving the Problems] The device according to the present invention divides a display provided inside an elevator car or at a landing into two display areas, and as the car approaches the landing (as the car approaches the landing, the first display In an apparatus for gradually decreasing a lighting area in a region and gradually increasing a lighting area in a second display region.

Each display area mentioned above includes a plurality of unit display areas, and a calculation means calculates and outputs the distance or time required for the car to arrive at the landing area, and a unit display amount setting means calculates and outputs the distance or time required for the car to arrive at the landing area, and the unit display amount setting means calculates and outputs the distance or time required for the car to arrive at the landing area. The distance or time represented by one unit display area is set according to the output of the calculation means, and the first display control means starts displaying from the state where the number of lit unit display areas in the first display area is set to the maximum number. As the output of the arithmetic means decreases, the number of lit unit display areas in the first display area is decreased based on the unit display amount set by the unit display amount setting means, and the first display control means il1 2. Display starts from a state where the number of lit unit display areas within the display area is set to the minimum number.

As the output of the calculation means becomes smaller, the number of lit unit display areas in the second display area is increased based on the unit display amount set by the unit display amount setting means.

[Effect]

The device according to the present invention is arranged so that an amount corresponding to the distance or time required for the car to arrive at the landing is displayed in one display area of a display provided in the car or at the landing in a state where the illuminated area of the display area is maximized. The display starts from , and gradually decreases the lighting area, and starts displaying in the other display area an amount equivalent to the distance or time d decreased from the time when the display of the display area started from the state where the lighting area becomes the minimum. The lighting area is gradually increased, the unit display amount is changed according to the distance or time at the time of starting the display, and the lighting area is decreased or increased based on the unit display amount.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is an overall configuration diagram for clearly showing the configuration of an embodiment of the present invention, in which the unit display amount setting means sets the display per unit display area according to the output of the calculation means A at the time of starting 9 displays. Set the amount. The display control means C displays the amount corresponding to the output of the calculation means A in such a manner that the lighting area of the first display area B1 is decreased from the maximum state based on the unit display amount set by the unit display amount setting means. The smaller the output of the first display control means o1 and the calculation means A, the more 8V! 2
and a second display control means c2 for displaying the lighting area of the display area B2 in such a manner that the lighting area increases from the minimum state based on the unit display amount set by the unit display amount setting means.

It consists of Note that the first display area B1 has an indicator light (
It consists of five unit display areas represented by 1) to (5),
The second display area B2 consists of five unit display areas represented by indicator lights (6) to (10).

FIG. 2 is a circuit diagram corresponding to FIG. 8 of the conventional example.

A unit display amount calculation device that outputs 0B).

(This is a constant value setting device that sets and outputs a constant value signal TI-T5 based on the 6-bit unit display amount signal (60a).

This constitutes unit display amount setting means. In this embodiment, it is assumed that the expected arrival time calculation device OJ outputs the expected arrival time signal (1) in 1 second increments.

Figure 3 shows the unit display amount calculating device (60) and constant value setting device (6 detailed circuit diagrams.

(72) to (75) are adders. Note that the constant value signal T1 is preset to 1 second.

Next, the operation of this embodiment will be explained.

Assume that a waiting customer operates the up button on the third floor to register an up call, and the 3 allocation device Oz allocates car No. 1 to this call.

At this time, the 3rd floor ascending assignment signal of Unit 1 (l I 3u)
KE rHJ, so 1 indicator light (11 to Q1. and (1
1A) to (IID) can be displayed. Therefore,
Estimated arrival time calculation device (assuming that the expected arrival time signal (tl) for going up to the 3rd floor of Unit 1 is calculated and output by 1 hot water is 20 seconds, then the unit display amount calculation device (for Ruri, 1
When the 3rd floor ascending assignment signal (113u) of the machine becomes rHJ, the pulse generator (62) emits a pulse signal (62), so the rHJ signal is input to the T point of the storage device (63), and the Estimated arrival time signal (t) (
-20 seconds) is stored. Then, the reference waiting time signal (63a) (-20 seconds) is output from point P, so the division arrival (
6li, the unit display amount signal (60a) is 20 seconds ÷ 5
-4 seconds is output. Furthermore, a constant value setting device (61)
Then, the adder (72) adds the constant value signal T2 id constant value signal TI (-1 second) and the unit display amount signal (60 seconds (=4 seconds) and outputs 5 seconds.Similarly, Adders (73) to (75) output constant value signals T3 to T5 as 9 seconds, 13 seconds, and 17 seconds, respectively.

Therefore, the outputs of comparators (2) to (c) are all rHJ
Therefore, the outputs of A and N D goo1-C'1ll- (to) both become rHJ, and the indicator lights +1) to (5) in the first display area B1 are all lit.

Also, the output of NOT gates (5 to 55) is r
LJ, and the outputs of AND gates (to) to (4α) also become rLJ, and the indicator light (61
~Ol remains off. The display state of the display UTI at this time is as shown in (8) in FIG. Note that the 1st indicator light (HA) to (++:o)H repeats blinking alternately at a 0.5 second cycle as in the conventional example, and the display in the first display area B1 and second display area B2 progresses. Guide the waiting customers.

Next, Unit 1 approaches the 3rd floor and the expected arrival time signal (1)
Suppose that changes from 20 seconds to 16 seconds, 12 seconds, 8 seconds, 4 seconds, and 0 seconds, then the comparators as, c: a, G! L(
c), Since the output of C+t+ becomes rHJ → rLJ in order, the indicator lights (51, +41. (
3), +21. (11 is the unit display amount signal (6011
), the lights will turn off in sequence every 4 seconds. Along with this, NO

(To), 09. [4G output is j@ rLJ → rH
Next to J.

Similarly, the indicator light (6) of the second display area B2 is displayed every 4 seconds.

(71, 181, +91. ,
(C1, (d), (8).

(f).

Then, when the first car arrives at the third floor in the upward direction, the third floor upward call is canceled and the assignment signal (113u) becomes rLJ, so even if the expected arrival time signal (1) has a value of 1 second or more, the first Indicator lights (1) to (5) in display area B1, second
The indicator lights (6) to (101) in the display area B2 and the indicator lights (iLA) to (11D) in the third display area B3 are turned off all at once. Also, in the unit display amount calculation device (60).

When the 3rd floor ascending assignment signal (++3u) of Unit 1 becomes rLJ, the output of the NOT gate (65) becomes rHJ and the rHJ signal is input to the R point of the storage device (63). The stored content is reset to zero and a unit display amount signal (60 seconds is output).

Therefore, in the constant value setting device (61), the constant value signals T1 to
T5 is set to 1 second in both cases.

Next, when the 3rd floor up call is assigned to Unit 1, 3
When the expected arrival time signal (1) for climbing the stairs is calculated and output as 40 seconds, the unit display amount signal (60 is 40÷5-8
Therefore, if the expected arrival time signal (1) is 20 seconds, then (compared to (8) in Figure 4 at half the speed)
The displays shown in ~(f) are performed in order.

In this embodiment, the unit display amount of the hourglass-like display is set according to the expected arrival time at the time of landing call allocation, and the arrival at the first display area B1, which is the upper part of the first display. The amount corresponding to the predicted time is reduced from the maximum lighting area based on the unit display amount, and the amount corresponding to the decrease in the predicted arrival time is displayed in the second display area B2, which is also in the lower part. The lighting area is displayed so that it increases from zero based on the amount of time, so that the meaning of the lighting area in each display area matches what the waiting customer imagines from the hourglass, and the time in between. Since the aging period is made clear, it is possible to reduce misunderstandings about the displayed contents and to reduce unnecessary feelings of irritation.

In the above embodiment, the situation in which a car approaches is displayed as a predicted value of the time until the car arrives at the landing, that is, the expected arrival time in the first display area, and the amount of decrease in the above expected arrival time after being allocated by 1 is calculated. Although it is displayed in the second display area, the method of representing the approaching situation of the car is not limited to this.

As a predicted value of the approaching situation of a car, for example,
As specified in Publication No. 5141, the number of floors that must be traveled before arriving at the boarding area in a predetermined direction may be used, or the number of floors that must be traveled and that must be stopped may be used. It is also easy to use.

Further, in the above embodiment, the number of unit display areas of the first display area and the second display area is each set equal to five, but
The number of unit display areas does not necessarily have to be equal. In this case, it is obvious that the unit display amount per unit display area may be set for each display area. Furthermore, the present invention can be applied to the case where the first display area and the second display area are subdivided into a plurality of areas having different display areas.

For example, the display area equivalent to the greatest common divisor may be treated as a unit display area, and the display hands represented by the divided areas may be set according to each display area.

Furthermore, in the above embodiment, unlike the conventional example, when a car arrives, the indicator lights (1) to 00.00 are displayed in the first to third display areas. and (11
Although A) to (HD) are all turned off, it is also easy to display an amount corresponding to the reduction in the expected arrival time at the time of arrival in the second display area until the door starts to open.

Further, in the above embodiment, a display is provided for each direction, but only one display may be provided for both up and down directions to display the approach status of the car in the direction in which the car will arrive first. Further, the present invention is applicable not only to a car but also to a car.

Furthermore, in the above embodiment, the approach status of the car is displayed in six stages, but the number of display stages is not limited to this. LED, liquid crystal, and plasma displays,
Furthermore, it is clear that the approach situation can be displayed in more detail by using a graph ink display using ORT. In addition, we use multiple types of lighting colors for the display, and use parts that should be turned off (
Even if the background (background) is displayed in a different lighting color, the effects of the present invention will not be impaired.

Furthermore, in the above embodiment, the 9 indicator was configured to resemble an hourglass, but it is not necessarily necessary to make it look exactly like an hourglass. If the display area of the display device is divided into two display areas, and as the car approaches the landing area, the lighting area of one display area gradually decreases, and the lighting area of the other display area gradually increases. The approach situation of the car can be easily understood by association.

〔Effect of the invention〕

As described above, according to the present invention, a display provided in an elevator car or a landing is divided into two display areas, and as the car approaches the landing, the lighting area in the first display area is gradually decreased, and in which the lighting area in the second display area is gradually increased, wherein each of the display areas includes a plurality of unit display areas, and the calculation means is used to calculate the size of the basket.
1. Calculate and output the distance or time required to arrive at the boarding area, and use the unit display amount setting means to determine the distance or time represented by one unit display area according to the output of the calculation means at the time of display start. setting, and the first display control means displays the first
Display starts with the number of lit units in the unit display area in the display area set to the maximum number, and as the output of the calculation means becomes smaller, the number of lit units in the unit display area in the first display area is set by the unit display amount setting unit. The unit display amount is decreased based on the set unit display amount, and the display is started from the state where the number of lit unit display areas in the second display area is set to the minimum number by the second display control means, and as the output of the calculation means becomes smaller, #R was configured to increase the lighting area of the unit display area in the second display area based on the unit display amount set above, so we will wait to see what the lighting area of these display areas means. You can avoid being misunderstood by customers, and avoid making waiting customers feel uncomfortable or suspicious.
