Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present 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]

Traditionally, passengers waiting at the landing for their car to arrive.
He learned the location and driving direction of the car from the movement of the car position indicator, determined which car would reach his floor first, and waited in front of the door of that car.

However, when the number of installed cars increases, it becomes extremely difficult to find a desired car based on the ever-changing car positions and driving directions. Therefore, as shown in Special Publication No. 56-20266,
The time required for a car that responds to a landing call to arrive at the landing is calculated, and this is displayed as a predicted waiting time for each car on the horseback ride, so that waiting customers can know how long they will have to wait for the car to arrive. A method has been proposed to eliminate the anxiety and impatience of waiting customers. However, this method of displaying the waiting time in numbers (hereinafter referred to as the numerical display method) has the advantage of making it easier for first-time customers to understand that the displayed content means the waiting time. When the predicted time and the current display content become inconsistent, the change in the display content is easily noticeable, which also creates a sense of distrust and irritation among waiting customers.

In addition, in order to solve the problems of the above numerical display method, as shown in Japanese Patent Application Laid-Open No. 54-47261,
A method has also been proposed in which the approach of a car is graphically guided by increasing the illuminated area of an indicator light (hereinafter referred to as a graphic display method). However, since this graphical display method graphically guides the approach of the car, it is difficult for passengers using this elevator for the first time to understand what the above display means, and in the end, the effect of the above display is not sufficient. There was a problem that it was not possible to perform effectively.

Therefore, in order to make it easier for even first-time users to understand the above display contents, and to avoid giving a sense of distrust or detail 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 provided 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 gradually increased accordingly. It has been proposed to display a situation in which a car is approaching. This will be explained with reference to FIGS. 5 to 9.

Fig. 5 is an overall configuration diagram to clearly show the configuration of a conventional example, in which A is an approach situation calculation means that calculates and outputs the situation when a car approaches a landing, and B is an indicator installed at the landing. Three display areas B
1, B2 and B3. C is a display control means that controls the two display areas B1 and B2 of the display B and the lighting area, respectively, and controls the display form of the display area B3. Based on the output of the approach situation calculation means A, C is a display control means that controls the lighting area of the two display areas B1 and B2, respectively, and controls the display form of the display area B3. As it approaches, the lighting area of the first display area is gradually decreased, the lighting area of the second display area is gradually increased, and at the same time, the lighting form of the third display area is periodically changed.

Figure 6 shows the landing on the 3rd floor of a 6-story building with two elevators, D1 and D2 are the landing doors of No. 1 and No. 2, respectively, and H
is the hall operation panel with an up button and a down button, U1 and U2 are the up hall lanterns for the first and second cars, respectively, L1 and L2 are the down hall lanterns, and UT1 and UT2 are the up call for the first and second cars, respectively. The uplink waiting time indicators, LT1 and LT2, which display the approach situation when responding to a downcall, are also downlink waiting time indicators which display the approach situation when answering a downcall.

Figure 7 shows the upstream waiting time display for Unit 1 on the 3rd floor.
This is a diagram showing details of UT1, in which 1 to 5 are indicator lights belonging to the first display area B1, respectively, and 6 to 10 are
are indicator lights belonging to the second display area B2, respectively;
11A to 11D are indicator lights belonging to the third display area B3, respectively.

FIG. 8 is a circuit diagram showing a display control circuit C1u that controls the uplink waiting time display device UT1 for the first car on the third floor among the display control means C. Similar circuits are used for the descending direction, other floors, and other cars. In the figure, 12 indicates the up call and down call registered by the hall operation panel H etc.
This is a well-known allocation device that outputs an allocation signal by assigning to car No. 1. 113u is an allocation signal that becomes "H" when car No. 1 is allocated to an up call on the 3rd floor, and becomes "L" when the allocated car responds to the above call. It is. 1
3 is the predicted value of the time it takes for Cars 1 and 2 to arrive at each landing on the 1st to 6th floors in the up and down directions in response to the car call and the assigned landing call, respectively (i.e., the expected arrival time) t is a well-known expected arrival time calculation device that calculates and outputs the expected arrival time signal (5
(second increments). Reference numeral 14 denotes a car control device for the No. 1 car that controls running operations such as determining the driving direction and running/stopping, and door opening/closing operations in order to respond to a call; 143u is an output from the car control device 14 of the No. 1 car; , when Unit 1 is assigned to the 3rd floor up call and responds to it and arrives at the 3rd floor in the up direction.
This is a signal immediately after arrival that becomes "H" only from the time the vehicle arrives until the door begins to open. 21 to 25 are comparators that set the output signal of point Z to "H" when the input signal of point X≧the input signal of point Y, and otherwise set the output signal of point Z to "L"; T1 to 25; T5 is T1<T2<
Those that satisfy the relationship T3<T4<T5, constant value signals set to 1 second, 6 seconds, 11 seconds, 16 seconds, and 21 seconds, respectively, 31 to 42 are AND gates, 45 to 4
9 is an OR gate, 50 is a pulse generator that outputs a pulse signal 50a that repeats "H" and "L" in order every 0.5 seconds, and 51 to 56 are NOT gates.

Figures 9 a to f are the upstream waiting time display UT in Figure 7.
FIG. 1 is a diagram showing changes in the display state of No. 1; (However, the shaded area indicates the lighting state.) Next, the operation of this conventional example will be explained.

Assume that a waiting customer operates an up button on the third floor to register an up call, and the allocation device 12 allocates car No. 1 to this call. At this time, the third floor up assignment signal 113u of the first car becomes "H". On the other hand, if the expected arrival time calculation device 13 calculates and outputs the expected arrival time signal t of No. 1 going up to the 3rd floor as 25 seconds, the outputs of the comparators 21 to 25 will all be "H", so The outputs of AND gates 31 to 35 all become "H", indicating lights 1 to 1 of the first display area B1.
5 lights up. On the other hand, since the outputs of NOT gates 51 to 55 are all "L", AND gate 3
The outputs of 6 to 40 also become "L", and the signal 1 immediately after arrival
Since 43u is also "L", OR gates 45-49
The output also becomes "L", and the indicator lights 6 to 10 in the second display area B2 remain off. Further, while the periodic pulse signal 50a is "L", the output of the AND gate 41 is "L", the output of the NOT gate 56 is "H",
Since the output of the AND gate 42 becomes "H", the indicator lights 11A and 11C are turned off and the indicator lights 11B and 11D are turned on. Conversely, while the periodic pulse signal 50a is "H", the output of the AND gate 41 is "H",
The output of NOT gate 56 is "L", AND gate 4
Since the output of No. 2 becomes "L", the indicator lights 11A and 11C are turned on and the indicator lights 11B and 11D are turned off. In the end, the combination of indicator lights 11A and 11C in the third display area B3 and the set of indicator lights 11B and 11D are 0.5
It will alternately turn on and off every second. This flashing indicates that the sand in the hourglass is falling. This blinking continues while the assignment signal 113u is "H". In this way, when the expected arrival time signal t takes a value equal to or greater than the constant value signal T5, the state shown in a of FIG. 9 occurs. (In addition, indicator light 11
(A to 11D flash.) Next, assume that the first vehicle approaches the third floor and the expected arrival time signal t changes from 25 seconds to 20 seconds. At this time, t (= 20 seconds) < T5 (= 21 seconds) and the comparator 2
Only the output of 5 changes from "H" to "L", so
The output of the AND gate 35 changes from "H" to "L",
The indicator light 5 in the first display area B1 is turned off. at the same time
Since the output of the NOT gate 55 changes from "L" to "H", the output of the AND gate 36 changes from "L" to "H", and the output of the OR gate 45 changes from "L" to "H", and the second display area The indicator light 6 of B2 lights up. Therefore, the display state of the display device UT1 at this time is the 9th display state.
It changes from a to b in the figure.

Furthermore, if Unit 1 approaches the third floor and the expected arrival time signal t changes from 20 seconds to 15 seconds, 10 seconds, and 5 seconds, the outputs of comparators 24, 23, and 22 will turn "H" → As it changes to "L", the outputs of AND gates 34, 33, 32 sequentially change from "H" to "L", and AND gates 37, 38, 39
The output of OR gate 4 goes from “L” to “H” in order.
The outputs of 6, 47, and 48 change from "L" to "H" in this order. Therefore, the indicator lights 4, 3, in the first display area B1
2 go out in order, and the indicator lights 7, 8, and 9 in the second display area B2 turn on in order. Therefore, when the expected arrival time t changes from 20 seconds to 5 seconds, the display
The display status of UT1 is c, d, c, d, in order from b in Fig. 9.
e.

Then, when the first car arrives at the third floor in the upward direction, the third floor upward call is canceled, the assignment signal 113u becomes "L", and at the same time, the immediately after arrival signal 143u becomes "H", and the expected arrival time signal t becomes 0 seconds. .
Therefore, the outputs of the AND gates 31 to 42 are all "L", so the indicator lamp 1 in the first display area B1
~5 and indicator lights 11A to 11 of the third display area B3
All D lights go out. Immediately after arrival, the signal 143u becomes "H", so the outputs of the OR gates 45 to 49 all become "H", so that all the indicator lights 6 to 10 in the second display area B2 are lit. At this time, the display
The display state of UT1 changes from e to f in FIG.

Finally, when Unit 1 starts opening its doors on the 3rd floor, immediately after arriving, signal 143u becomes "L" and OR gate 45
Since all of the outputs from 49 to 49 become "L", the indicator lights 6 to 10 in the second display area B2 are all turned off, resulting in the same state as before the hall call was registered. In addition, when the call for going up to the third floor is assigned to machine No. 2 instead of machine No. 1 (assignment signal 113u = "L"),
The outputs of AND gates 31 to 42 are all "L"
Therefore, the display UT1 of Unit 1 remains off, so as not to confuse passengers waiting for Unit 2.

In this way, in the above conventional example, when the expected arrival time t becomes smaller as the car approaches, the area where the indicator lights in the first display area B1 are lit is reduced, and at the same time, the area where the indicator lights are lit in the first display area B1 is reduced. By increasing the area where the indicator light is lit from zero,
The approach status of the car is displayed in an hourglass-like display, so that even first-time customers can understand the displayed content.

[Problem that the invention seeks to solve]

However, in the conventional example, the waiting time represented by the lighting area of one indicator light is 5 seconds, so the maximum waiting time (estimated arrival time) that can be displayed at the time of hall call assignment is limited to 25 seconds. Therefore, when the expected arrival time is, for example, 40 seconds, the display starts from the state a in Figure 9, and gradually changes to this state (the top of the hourglass is full of sand) until the expected arrival time reaches 20 seconds. , and the sand is falling), so it is impossible to judge whether the waiting time until the car arrives is exactly the maximum waiting time, or whether you will have to wait longer than that. This was unnecessarily making waiting customers feel suspicious and anxious.

This invention was made in order to solve the above-mentioned problems, and it uses a display divided into two display areas to guide the approach situation of a car. To provide an elevator display device that does not make passengers feel unnecessarily anxious or suspicious even when the predicted time (expected time) exceeds the maximum amount that can be displayed with the lighting area of these display areas (for example, the maximum waiting time). The purpose is to

[Means for solving problems]

The device according to the present invention includes a calculation means for calculating and outputting the distance or time required for the car to arrive at the landing area by providing three types of display areas on a display provided in the elevator car or at the landing area; As long as predetermined conditions are met regarding the boarding area,
A display command means for outputting a command for operating the display; a first display control for displaying an amount corresponding to the output of the calculation means in a lighting area of a first display area when the display command means is operating; means, a second display control means for increasing the lighting area of the second display area in response to a decrease in the lighting area of the first display area, and the first display control means and the second display means. A third display control means for displaying that a decreasing operation and an increasing operation are being performed by changing the lighting form of the third display area,
When the output of the calculation means exceeds the amount corresponding to the maximum lighting area of the first display area, the display command means instructs the first display control means to display the maximum lighting area, and the second instructing the display control means to display in the minimum lighting area, and instructing the third display control means to prevent the display operation, and also instructing the output of the arithmetic means to reach the maximum lighting area of the first display area. When the amount is less than the corresponding amount, the first display control means is instructed to display with the corresponding lighting area, and the second display control means is increased to increase the lighting area in accordance with the decrease in the lighting area in the first display area. The third display control means is configured to command the third display control means to perform the display operation.

[Effect]

In the device according to the present invention, the amount corresponding to the distance or time required for the car to arrive at the landing exceeds the amount corresponding to the maximum lighting area of the first display area of the display provided in the car or at the landing. At this time, the lighting area of the display area is displayed at a maximum, the lighting area of the second display area is displayed at a minimum, and the display operation of the third display area is inhibited. When the amount corresponding to the distance or time is less than the amount corresponding to the maximum lighting area of the first display area of the display, the lighting area of the first display area is gradually increased according to the amount corresponding to the distance or time. The lighting area of the second display area is gradually increased in accordance with the decrease of the lighting area of the first display area, and a display operation of the third display area is performed.

[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 display control means C includes a first display area B1 that displays an amount corresponding to the output of the calculation means A in the lighting area of the first display area B1. When the display control means C1 and the first display control means C1 start operating, as the lighting area in the first display area B1 decreases, the second display control means C1 starts operating.
The second display control means C2 increases and displays the lighting area of the display area B2 from the specified state, and the second display control means C2 displays the lighting area of the first display area B1 and the second display area B2 to indicate that the lighting areas of the first display area B1 and the second display area B2 are decreased or increased. 3rd display control means C that periodically changes the lighting form of the 3rd display area B3
It is composed of 3. D is the calculation means A
When the output of exceeds the amount corresponding to the maximum lighting area of the first display area B1, the first display control means C1 is commanded to display the maximum lighting area, and the second display control means C2 is instructed to display the minimum lighting area ( = zero), and commanded the third display control means C3 to prevent the display operation, and the output of the calculation means A corresponds to the maximum lighting area of the first display area B1. When the amount is less than or equal to the amount, the first display control means C1 is instructed to display with a lighting area corresponding to the output of the calculation means A, and the second display control means C2
to increase the lighting area from the minimum lighting area or larger in accordance with the decrease in the lighting area in the first display area B1, and instruct the third display control means C3 to perform the display operation. This is a display command means for commanding.

Figure 2 is a circuit diagram corresponding to Figure 8 of the conventional example,
It is a circuit diagram which shows the display control circuit C1u which controls the uplink waiting time display UT1 for the 1st car of the 3rd floor among the display control means C. Similar circuits are used for the descending direction, other floors, and other cars.
In the figure, 26 to 30 are comparators similar to comparators 21 to 25, and E1 to E5 are E1<E2<E3<E4<E
Those that satisfy the relationship 5 are 5 seconds, 10 seconds, and 15, respectively.
Constant value signal set as seconds, 20 seconds, 25 seconds, 51~
55 is an OR gate, and 61 is a display command device 71 (described later) that stores an expected arrival time signal t on the 3rd floor of Unit 1 immediately after a second display command signal 71b (described later) becomes "H"; 71 is a display command device corresponding to display command means D, which is installed on the 3rd floor of Unit 1. A first display command signal 7 that is assigned to an uplink call and becomes "H" when the expected arrival time signal t is equal to or higher than a certain signal T6 (described later).
1a, and the expected arrival time signal t is a constant value signal T6.
(described later), a second display 1 command signal 71b that becomes "H" is output.

FIG. 3 is a detailed circuit diagram of the reduction amount calculating device 61 and display command device 71. In the figure, when the input signal at point 62 changes from "L" to "H", it becomes "H" for only 0.5 seconds. A pulse generator 63 that outputs a pulse signal 62a stores the value of the input signal at point T when the input signal is "H", and sets the stored content to zero when the input signal at point R is "H". The storage device to be reset outputs its storage contents from point P as a reference waiting time signal 63a. 64 is a subtracter, 65
is a NOT gate, 72 is a comparator similar to the comparator 21, 73 is a NOT gate, 74 and 75 are AND gates, and T6 is a constant value signal representing 26 seconds.

Next, the operation of this embodiment will be explained.

Assume that a waiting customer operates an up button on the third floor to register an up call, and the allocation device 12 allocates car No. 1 to this call. At this time, expected arrival time calculation device 1
3, the expected arrival time signal t for Unit 1 going up to the 3rd floor
is calculated and output as 40 seconds, the output of the comparator 72 in the display command device 71 is "H",
Since the output of NOT gate 73 is "L",
The first display command signal 71a becomes "H" by the AND gates 74 and 75, and the second display command signal 71b
becomes "L". Therefore, in the display control circuit C1u of FIG. 2, the outputs of the OR gates 51 to 55 are all "H", so the indicator lights 1 to 5 in the first display area B1 are all turned on, and the AND gates 36 to 4 are turned on.
Since all outputs of 0 become "L", the indicator lights 6 to 10 in the second display area B2 remain off. Moreover, the AND gate 41 and the output are both "L", and the indicator light 11A of the third display area B3
The periodic blinking display by ~11D is blocked. On the other hand, in the reduction amount calculating device 61, since the second display command signal 71b is "L", the NOT gate 6
5 becomes "H", and since the "H" signal is input to the R point of the storage device 63, its stored content remains zero.

In this way, when the expected arrival time t for going up to the third floor at the time of allocating a call for going up to the third floor is equal to or greater than the constant value T6 (=26 seconds), the display UT1 will display as shown in FIG. 4a.

Next, Unit 1 gradually approaches the 3rd floor, and the expected arrival time signal t for Unit 1 going up to the 3rd floor is 35 seconds, 30 seconds, 25 seconds.
If it is calculated and output in order of seconds, the output of the comparator 72 becomes "L" immediately after the expected arrival time signal t reaches 25 seconds in the display command device 71. Therefore, NOT gate 73, AND gates 74 and 7
5, the first display command signal 71a becomes "L" and the second display command signal 71b becomes "H". In addition, in the reduction amount calculating device 61, when the second display command signal 71b becomes "H", the pulse signal 62a is emitted by the pulse generator 62, so an "H" signal is input to the T point of the storage device 63. The expected arrival time signal t (=25 seconds) at that time is stored (at this time, an "L" signal is input to point R). Then, from point P, the reference waiting time signal 63a (=
25 seconds), the subtracter 64 outputs the decrease amount signal 61a as 0 seconds.

Therefore, since the outputs of the comparators 21 to 25 are all "H", the outputs of the AND gates 31 to 35 are also "H", and the display control circuit C in FIG.
At 1u, the outputs of the OR gates 51 to 55 all become "H", so all the indicator lights 1 to 5 in the first display area B1 remain lit. Also, since the decrease amount signal 61a is zero seconds, the outputs of the comparators 26 to 30 are all "L", and the AND gates 36 to 4
The outputs of 0 also become "L", and the indicator lights 6 to 10 in the second display area B2 remain off. Further, since the outputs of the AND gates 41 and 42 are alternately "H" and "L", the periodic blinking display by the indicator lights 11A to 11D in the third display area B3 is started.

In this way, the expected arrival time t is a constant value T6 (=
26 seconds), the display state of the display UT1 becomes as shown in Fig. 4b (9th in the conventional example).
(corresponds to a in the figure). In addition, the indicator lights 11A to 11
D repeats blinking alternately at a 0.5 second period as in the conventional example, and displays the first display area B1 and the second display area B2.
Inform waiting customers that the display is progressing.

Next, as Unit 1 approaches the third floor, the expected arrival time signal t changes from 25 seconds to 20 seconds, 15 seconds, 10 seconds, and 5 seconds.
If it changes from 0 seconds to 0 seconds, comparators 25 and 2
The outputs of 4, 23, 22, and 21 are "H" in order →
Since it becomes "L", the indicator light 5 of the first display area B1,
4, 3, 2, and 1 are turned off in order every 5 seconds according to the unit display amount signal 60a. On the other hand, the decrease amount calculation device 61 sequentially outputs the decrease amount signal 61a from 0 seconds to 5 seconds.
As it changes from second, 10 seconds, 15 seconds, 20 seconds, and 25 seconds, the comparators 26, 27, 28, 29, 30
The output of the gates changes from "L" to "H" in order, and accordingly, the AND gates 36, 37, 38, 39, 4
The output of 0 becomes "L" → "H" in order, and the output becomes 5 as well.
The indicator lights 6, 7, 8 of the second display area B2,
9 and 10 light up in order. After all, when the expected arrival time signal t changes from 25 seconds to 0 seconds, from b, c, d in FIG. 4 to b, c, d in FIG.
It changes to e and f. Note that the expected arrival time signal t
When is 0 seconds, the indicator light 11A differs from the conventional example.
~11D blinks at a 0.5 second cycle.

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 “L”, so the AND of the display command device 71
The first display command signal 71 is output by gates 74 and 75.
a and the second display command signal 71b both become "L". Therefore, even if the expected arrival time signal t has a value of 1 second or more, the indicator lights 1 to 5 in the first display area B1,
The indicator lights 6 to 10 in the second display area B2 and the indicator lights 11A to 11D in the third display area B3 are turned off all at once. In addition, in the reduction amount calculating device 61, when the second display command signal 71b becomes "L", the NOT gate 6
5 becomes "H" and an "H" signal is input to the R point of the storage device 63, so the stored contents of the storage device 63 are reset to zero and the reference waiting time signal 63
a is output as zero seconds.

Estimated arrival time t for going up to the 3rd floor at the time of allotment of calls for going up to the 3rd floor
is less than the constant value T6 (=26 seconds), for example, 15
When the time is seconds, the first display command signal 71a is “L”;
Since the second display command signal 71b becomes "H", 15 seconds is stored in the storage device 63 by the pulse signal 62a, and the reference waiting time signal 63a is output as 15 seconds.
Therefore, the decrease amount signal 61a is output as 0 seconds, and the outputs of the comparators 21 to 23 at this time are "L".
→ becomes “H” and the outputs of comparators 21 to 23 are “L”
Therefore, the indicator light 1 in the first display area B1
~3 lights up, and indicator lights 6~1 in the second display area B2
0 remains off. The indicator lights 11A to 11D in the third display area B3 blink at a period of 0.5 seconds. From then on,
As the expected arrival time t changes from 15 seconds to 10 seconds, 5 seconds, and 0 seconds, the indicator lights 3 to 1 in the first display area B1
turn off in order, and the indicator lights 6 to 8 in the second display area B2
lights up in sequence.

As described above, in this embodiment, when the expected arrival time at the time of landing call allocation exceeds the time corresponding to the maximum lighting area of the first display area of the display provided at the landing, the lighting area of the display area is The lighting area of the second display area is displayed in the maximum state, the lighting area of the second display area is displayed in the minimum state, and the display operation representing the falling state of sand in the third display area is inhibited. and when the expected arrival time at the time of the hall call allocation is less than or equal to the time corresponding to the maximum lighting area of the first display area of the display, the lighting area of the first display area is gradually decreased in accordance with the expected arrival time; The lighting area of the second display area is gradually increased as the lighting area of the first display area decreases, and a display operation is performed to indicate the state of falling sand in the third display area. can determine whether the waiting time until the car arrives is exactly the maximum time that can be displayed, or whether the customer will have to wait longer than that by looking at whether the display indicating the sand falling state is being displayed. , it can reduce unnecessary feelings of suspicion and impatience.

In the above embodiment, the situation in which the car approaches is displayed in the first display area as a predicted value of the time until the car arrives at the landing, that is, the expected arrival time, and the amount of decrease in the expected arrival time after allocation 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 approach situation of a car, for example, as specified in Japanese Patent Application Laid-Open No. 52-5141, the number of floors that must be traveled before arriving at a landing in a particular direction may be used. However, it is also easy to use the planned number of floors at which the vehicle must stop.

Further, in the above embodiment, unlike the conventional example, when a car arrives, the indicator lights 1 to 10 in the first to third display areas,
and 11A to 11D are all turned off, but it is also easy to display an amount corresponding to the amount of decrease 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, an indicator is provided for each direction, but only one indicator 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 can be applied not only to a car at a landing but also to a car.

Furthermore, in the above embodiment, the approach status of the car is displayed in six stages, but the display stages are not limited to this. It is clear that the approaching situation can be displayed in more detail by using LEDs, liquid crystal plasma displays, or even CRT graphic displays. In addition, multiple types of lighting colors are used for the display, and areas that should be turned off (background)
The effects of the present invention will not be impaired even if it is displayed in a different lighting color.

Furthermore, in the above embodiment, the display device is configured to resemble an hourglass, but it is not necessarily necessary to make it resemble an hourglass. If the display area is divided into two display areas, and as the car approaches the landing area, the lighting area of one display area is gradually decreased and the lighting area of the other display area is gradually increased.
The approaching situation of the car can be easily understood by association with the hourglass.
