DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for displaying the situation in which an elevator car approaches a landing.

[Conventional technology]

Figures 1a to 12 are 1, for example, Japanese Patent Application No. 1983-925, 7.
FIG. 10 is a front view of the third-floor landing, FIG. 11 is a front view of the up-waiting time display, and FIG. 12 is an operation explanatory diagram.

In the figure, DI and D2 are the up lights of the arrival forecast lights of Unit 1 and Unit 2, which are placed above Unit 1 and Unit 2 D2, respectively, and II; 112 is the same (outgoing light).

UTI and UT2 are up-bound waiting time indicators that display the approach status when the first and second cars respond to a call going up the landing, respectively, and LTI and LT2 are down-waiting time indicators that also display the approach status when they respond to a call going down the hall. Time indicator, (
1) to (5) are each arranged in series in the first display area B.
The indicator lights belonging to 1, (6) to αal are the first display area B
Indicator lamps arranged in series below 1 and belonging to the second display area B2* (IIA) to (11D) are arranged in series between the first and second display areas Bl and B2 and belong to the third display area B
This is an indicator light belonging to category 3. In this way, the upstream and downstream waiting time indicators UTI, UT2°Lte1, and LT2 are each configured in an hourglass shape.

The conventional elevator display device is constructed as described above, and its operation will be explained with reference to FIG.

Assume that an up call is registered by the up button of the hall button H at the landing on the third floor, and car No. 1 is assigned to this up call by an assignment device (not shown) of the well-known group management device. On the other hand, the expected arrival time calculation device (not shown) of the ninth group management device calculates the expected arrival time t from the current position of the No. 1 car until it responds to the up call on the third floor. The lighting of the 9 indicator lights (1) to 15) and +61 to α1 is controlled based on the relationship between the expected arrival time t and the predetermined times T1 to T5, and the change in the lighting area changes the waiting time of the 9 landings and the number of cars. It displays the approaching situation. Note that the predetermined times T1 to T5 are as follows.

? ? <T 2 < T 3 < T 4 < T 5, and are set to 1 second, 6 seconds, 11 seconds, 16 seconds, and 21 seconds, respectively.

Now, if the expected arrival time t is calculated as 20 seconds,
The state is T4≦t(T5, and the indicator lights (1) to (4) in the busy first display area B1 are lit as shown in FIG. 12(b). The indicator light (5) is off. , only the indicator light (6) in the second display area B2 lights up, and the other indicator lights (7) to
All O1 lights are off. On the other hand, the indicator light (IIA), (+10) and indicator light (11B) of the third display area B3
, (11D) displays the state in which the sand in the hourglass is falling by repeatedly turning on and off alternately every O and S seconds.

Next, when Unit 1 approaches the third floor and the expected arrival time t is calculated to be 15 seconds, the state becomes T3≦t(T4, and the first
As shown in Figure 2 (C), the indicator lights (4
) goes out, and the indicator light (7) in the second display area B2 is additionally turned on.

Similarly, the expected arrival time t is 10 seconds and 5 seconds thereafter.

Assuming that the time changes to 0 seconds, T2≦t<T3, respectively.
゜T 1 j5t(T 2. t(The state of T 1 is reached, and as shown in FIG. 12(d) to (f), the indicator lights (3) to (11) in the first display area B1 turn off in sequence, and the The indicator lights (8) to α1 in the second display area B2 are lit in sequence.
When the car reaches the third floor, all 9 indicator lights (1) to αl are turned off.

In this way, the estimated arrival time is displayed using the illuminated area of the first display area B1, which corresponds to the upper part of the hourglass.

The approaching status of the car is displayed by gradually decreasing the lighting area of the first display area B1 and gradually increasing the lighting area of the second display area B2, which corresponds to the lower part of the hourglass, and by alternately blinking the third display area B3, the estimated arrival time is displayed. and displays the elapsed time to inform you that it is progressing.

[Problem that the invention seeks to solve]

In the conventional elevator display device as described above, the first
By gradually decreasing the lighting area of the display area B10 and gradually increasing the lighting area of the second display area B2, the waiting time is simply displayed by simulating an hourglass, so that the car can arrive in either direction, up or down. There is a problem in that it is not possible to display the direction of the vehicle, and for that purpose, another direction indicator must be used.

This invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide an elevator display device that uses an hourglass-shaped display to display both the waiting time and the driving direction of the car at the same time. .

[Means for Solving the Problems] An elevator display device according to the present invention includes an expected arrival time calculation means for calculating the time required for a car to arrive at a landing, and a quantity corresponding to the output of this calculation means. A first display control means outputs the display area of the first downward display area of the display device during downward operation of the car, and the display area of the first downward display area of the display unit remains the same during upward operation (the display area of the first upward display area is gradually decreased). When driving uphill, the display area of the second downhill display area corresponds to a gradual decrease in the display area of the first downhill display area, and when driving uphill, the display area remains the same (the first uphill
A second display control means is provided for gradually increasing the display area of the second upward display area in response to the gradual decrease in the display area of the display area.

Next, the operation of this embodiment will be explained with reference to FIGS. 8 and 9.

Now, if a waiting customer on the 3rd floor operates the down button to register a down call, and the 9 allocation device σ2 assigns this call to car 1 at t, then the 3rd floor down allocation signal (N3D) of car 1
becomes rHJ and 9 indicator lights (1D) ~ (lop),
(+ +p,) to (HD) display becomes possible.

On the other hand, it is assumed that the expected arrival time signal (1) for descending the third floor of I+jPA is calculated to be 25 seconds by the expected arrival time calculation device a3. At this time, the down driving signal (+5D) is rHJ
, so the expected arrival time signal (1) passes through the gate circuit (IG) and becomes the output (+6a), and the comparator C11
Both outputs of l-(2) become rHJ. Now, A
Since all the outputs of the ND gate C1l+- (to) become rHJ, the indicator light (1D) of the downlink first display area BDI
~(5D) lights up.

On the other hand, there is a decrease: In the arithmetic unit α4, the 3rd floor descending assignment signal (++3D) of Unit 1 becomes rHJ, and the OR gate ■
When the output (20a) of K becomes rHJ, a pulse signal (72) is emitted from the pulse generator (72) K, so the expected arrival time signal (72) at that time is stored in the storage device (73).
t) (25 seconds) is stored, and the standard waiting time signal (73) is output.Now, the expected arrival time signal (t) (25 seconds) is input to the point (to) of the subtractor (74). It is.

Since the reference waiting time signal (73s (25 seconds)) is input to point (g), the decrease amount signal (+4a) is output as zero seconds.

It passes through the gate circuit αa and becomes an output (+8a). Therefore, the outputs of comparators (1) to (to) are all rLJ, and the outputs of AND gates (to) to (IQ are all "L
”, and the indicator light (6D
) to (IOD) remain off. The display state of the display B at this time is as shown in FIG. 8(a).

In addition, the periodic pulse signal from the 9-period pulse generator @j (
43fi) is rLJ, the output of the AND gate Oυ is "
The output of the A'ND gate f43 is rHJ, so the 9 indicator light (IIA
) (ha) goes out and the 9 indicator light (11B, (HD)
lights up. Conversely, the periodic pulse signal (43a) is rHJO
During the interval, the output of AND gate ht+ is "I (J, the output of NOT gate 04 is rLJ,

(HD) will alternately turn on and off every 0.5 seconds. These indicator lights (1D) ~ (+0D)
(IIA) to (110) represent the state in which the sand in the hourglass is falling. This flashing is an assignment signal (++3D)
continues during rHJO.

Next, Unit 1 approaches the 3rd floor and the expected arrival time signal (1)
Suppose that time changes from 25 seconds to 20 seconds.
0 seconds)/T5 (21 seconds), and only the output of the comparator (to) becomes rLJ, so the output Fi of the AND gate (to)
rLJ, and the indicator light (
5D) goes out. Further, the subtracter (74) of the reduction risk calculating device α4 calculates that the output (73a) (25 seconds) - t (20 seconds)≧5 seconds, and the output (14 becomes 5 seconds).

Now, only the output of the specific sensor (A) becomes [HJ, so
The output of the AND gate (to) becomes rHJ, and the indicator light (6D) in the second downward display area BD2 lights up.

This state is shown in FIG. 8(b). From then on, the expected arrival time signal (1) changes from 20 seconds to 15 seconds, 10 seconds, 5 seconds, and 0.
Suppose that the output of comparator t24)~Qυ is j
1 becomes rLJ, and the indicator lights (4D) to (ID) in the first downward display area BDI are sequentially turned off. Follow this.

Decrease amount signal (14 is 10 seconds, 15 seconds, 20 seconds and 25 seconds)
Since the outputs of comparators (5) to C1 change in order Kr
HJ, and the indicator light (7) of the downhill first display area BD2
D) to (l OD) are lit sequentially. In the end Ntl
, When the M expected time signal (1) changes from 25 seconds to 0 seconds, the display will be displayed as shown in Figure 8 (0) to (f). Unit 1 will be heading down to the 3rd floor. When the train arrives at the 3rd floor, the 3rd floor down call is canceled and the assignment signal (lI3D) becomes rLJ, so all of the 1 indicator lights (1D) to (+OD) ld go out. In addition, when the decrease amount calculation device arrives at 0, the 9 allocation signal (+
++D) becomes rI,J, the output (20a) of the OR gate (20a) also becomes rLJ, the output of the NOT gate (75) becomes rHJ, and the storage contents of the storage device (73) are reset to zero.

Next, in the case of uphill driving, the expected arrival time signal (1) is outputted (17) via the gate circuit αη, and the decrease amount signal (+4a) is outputted 09 via the gate circuit a9. When the expected arrival time signal (1) is output as 25 seconds, the outputs of the comparators (51) to (55) are all rH.
J, and the indicator light (1
U) to (5U) are all lit. On the other hand, the decrease amount signal (
+48) is 0 seconds, so the comparators (56) to (6
Both outputs are rLJ, and the second up display area BU
All of the indicator lights (602 to (+oty)?i) of No. 2 are off. This state is shown in FIG. 9(a). From now on.

As the car approaches the third floor, the indicator light (1
U) to (5U) turn off in sequence, and 9 indicator light (6■)
- (10H) are lit in sequence, and (1) 1 - (f
) is displayed as shown. In addition, 9 indicator lights (IIA),
(+10), indicator lights (++B) and (uD) flash alternately, and together with the operation of 9 indicator lights (1U) to (+OU), it indicates that the sand in the hourglass is floating.

In this way, during downhill driving, the amount corresponding to the expected arrival time is displayed in the display area of the second downhill display area BDI, which is the upper part of the display B, and the amount corresponding to the expected arrival time is displayed in the first downhill display area BD2, which is also the lower part. The amount corresponding to the decrease in the expected time is displayed so that the display area increases from a zero state to indicate a state in which the car is driving down and approaching. In addition, when driving up, the display area of the second up display area BU1, which is the lower part, is moved to the second up display area BU2, which is the upper part, to display the state in which the car is driving up and approaching.

〔Effect of the invention〕

As explained above, in this invention, during downhill driving, the display area of the first downhill display area corresponding to the upper part of the display device is gradually reduced in accordance with the estimated arrival time, and the display area of the second downhill display area corresponding to the lower part is gradually reduced. During uphill operation, the display area of the first upward display area corresponding to the lower part of the display is gradually decreased, and the display area of the second downward display area corresponding to the upper side is gradually increased. on the display.

This has the advantage of being able to display both the waiting time and the driving direction of the car at the same time so as to provide a sense of reality.
