Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for predicting the arrival of a car to customers waiting in an elevator hall.

At the landing of an elevator where multiple cars are arranged side by side, arrival warning lights are usually installed to display the arrival of the cars to waiting passengers at the hall.

The arrival warning light turns on when a car approaches the floor where the landing button has been pressed, and indicates to waiting customers the arrival of the car and the direction in which it will be serviced.

In this way, the arrival forecast light is turned on after the arrival of a car is determined, so the waiting customer does not know when and which car's arrival forecast light will be lit.

Therefore, passengers wait at appropriate positions,
After the arrival forecast light turns on, the car will move to the door of the car.

For this reason, waiting customers must always pay attention to which car's arrival forecast light is lit.

If you fall asleep and are late in noticing the light, the car you arrived at will leave while you are moving to the car that is lit, and you will miss the car.

In order to prevent such problems, recently it has been practiced to make the arrival forecast light blink so that waiting customers can quickly notice that the arrival forecast light has been turned on.

This certainly improved the effect of alerting the waiting customers. However, since the time from the start of the flashing until the arrival of the car is still unknown, if the movement of moving to the front of the hall door is slow, the car may fail to board the car.

Also, when you arrive at the boarding area, the arrival warning light may already be blinking. At times like this, you don't know how long it will take from the start of the flashing to when the basket arrives, so you might be walking thinking that you still have plenty of time, but you'll find that the door has already arrived and the door is open, and you can't wait to put it in the basket. Things also happen.

This invention improves the above-mentioned problem by displaying the approaching car from the time the forecast light turns on until the car arrives at the landing, so that passengers waiting at the landing can wait in line with the display. The purpose of the present invention is to provide an elevator arrival forecasting device that can predict the arrival of an elevator.

Furthermore, another object of the present invention is to provide an arrival forecasting device with a simple configuration to achieve the above object.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In Figure 1, + and - are DC power supplies, and 1a and 1b are deceleration command relays (not shown) that are energized when the car receives a stop command during upward operation and starts deceleration, and are deenergized when the car stops. Normally open contacts 2a and 2b are also normally open contacts of a deceleration command relay (not shown) for descending operation, 3 is a flashing relay that flashes the arrival forecast light, and 3a to 3c are normally open contacts, 3
d is a normally closed contact; 4 is an extinguishing time relay that is energized immediately when power is supplied; and is deenergized after a predetermined time (described later) by capacitor 6 when power is cut off; 4a;
5 is the normally closed contact, and 5 is the lighting time relay.
a is its normally open contact, 7 and 8 are protective resistors, 9 is a rectifier connected in parallel to the resistor 7, 10a and 10b are discharge resistors connected in parallel to the capacitor 6, and 11 to 1
4...A position switch that is closed between when the car starts decelerating and when it stops landing on the floor; 15 is an arrival warning light that indicates that the direction in which the car is to be serviced is the upward direction; 16 is an arrival warning light It is also an arrival forecast light that indicates the direction of descent.

Note that the time limit of the time relay 4 is for a short time, e.g.
The time limit of the time relay 5 is set to 0.2 seconds, and as will be described later, when the position switches 11 to 14... are all open, the position switches 11 to 14... are sequentially closed at 2 seconds, for example. It is set to gradually decrease as the time progresses to 1.5 seconds, 1 second, 0.5 seconds, and 0.2 seconds.

Assume that the car is currently in ascending operation. Since the flashing relay 3 is deenergized, the contact 3d is closed, and the time relay 5 is energized and the contact 5a is closed. Since the car stops at the floor where the stop command was received, when deceleration starts, contacts 1a and 1b close.

Here, a circuit of (+)-1a-4a-3-(-) is formed, and the flashing relay 3 is energized to contact 3a.
is closed. In addition, the contact 3c is also closed, and (+)-3
The arrival forecast light 15 for that floor is lit by the c-1b-15-(-) circuit. At the same time, contact 3b is also closed, time relay 4 is energized, and contact 4a is opened.

At the same time, contact 3d is also opened and timed relay 5
The circuit of capacitor 6 is broken, but the circuit of 6-7-
Due to the discharge through the circuit 5-8-6-, the timed relay 5 is not deenergized immediately and the resistors 7, 8, 1
With the time constant determined by 0b, 2
The second is energized.

Therefore, (+)-1a-3a-5a-3-
The flashing relay 3 is energized by the (-) circuit.

Thereafter, when the discharge current of the capacitor 6 attenuates and becomes equal to or less than the holding current of the time relay 5, the time relay is deenergized, the contact 5a is opened, and the time relay 3 is deenergized.

As a result, the contact point 3c is opened, and the arrival forecast light 15 is turned off. At the same time, the contact 3b is also opened and the circuit of the time relay 4 is cut off, and as in the case of the time relay 5, the time relay 4 is deenergized after 0.2 seconds by the time constant determined by the resistors 7, 8, and 10a. On the other hand, the contact 3d is closed and the time relay 5 is energized to prepare for subsequent operation.

Now, as the time relay 4 is deenergized, the contact 4a is closed, and the time relay 3 is energized again by the (+)-1a-4a-3-(-) circuit. As a result, the contact point 3c is closed again, and the arrival forecast light 15 is turned on.

From now on, repeat the same operation, arrival warning light 15
flashes at a cycle of 2 seconds on and 0.2 seconds off.

During this repeated flashing operation, when the car approaches the stop floor and the position switch 11 is closed, the resistance of the discharge resistor 10b of the capacitor 6 becomes small.
The attenuation speed of the discharge current of the capacitor 6 is increased. Therefore, the time limit of the timed relay 5 becomes shorter, the energization time of the flashing relay 3 becomes 1.5 seconds, and the arrival forecast light 15 flashes at a cycle of 1.5 seconds on and 0.2 seconds off.

When the car gets closer and the position switch 12 is closed, the time limit of the time relay 5 becomes even shorter in the same way as above, and the arrival forecast light 15 lights up for 1 second.
Flashes at a cycle of 0.2 seconds off.

In this way, as the position switches 13 and 14 close one after another, the lighting time of the arrival forecast light 15 increases.
The flashing period of the arrival forecast light 15 becomes shorter, 0.5 seconds, 0.2 seconds.

When the car arrives at the floor, the deceleration command relay is deenergized and the contact 1a is opened, so the flashing relay 3 is deenergized and returns to the initial state.

However, although not shown, the arrival forecast light 15 is turned on by a known circuit and continues to be lit until the car departs.

Figure 2 shows the above blinking situation. The car starts decelerating at point a, and the arrival forecast light turns on for t ₁ seconds (equivalent to 2 seconds in the above explanation) for t ₀ seconds (equivalent to 2 seconds in the above explanation).
Flashes at a cycle of 0.2 seconds).

Point b becomes point c when position switch 11 is closed.
-e are when the position switches 12-14 are closed, respectively. And position switches 11 to 14
, the lighting time decreases from t ₂ to t ₅ seconds.

Point f is when the car arrives.

In this way, the arrival forecast light 15 gradually reduces the blinking period by shortening the lighting time of the blinking time as the arrival forecast light 15 approaches the floor.

Therefore, the waiting passengers can know that the car is approaching the floor from time to time, so they hurry to the door of the landing.

In the above embodiment, the forecast was described while the car was in the ascending operation, but it will be easily understood that the arrival forecast light 16 flashes even during the descending operation. At this time, the timer for gradually reducing the flashing cycle used for the above-mentioned upward direction arrival forecast light 15 is also used for the descending arrival forecast light 16, and the ascending and descending arrival forecast lights are independent of each other. There is no need to provide a timer, which is very convenient in terms of manufacturing. Furthermore, even if one timer is used for both ascending and descending arrival prediction operations, one car will not ascend and descend at the same time.
There is no problem in practical use either.

Further, in the above embodiment, the lighting time of the arrival forecast light 15 is gradually reduced and the light-off time is always constant. You can also connect. In this way, it becomes possible to gradually reduce both the lighting time and the light-off time.

Furthermore, the time relays 4 and 5 can also be constructed by static circuits of flip-flops using electronic components. In this case, it is also possible to provide a continuous time change using a flip-flop that inputs a preset attenuation or increase pattern.

Furthermore, although the above embodiment is a case in which the blinking cycle is divided into five stages, at least two stages would be quite effective as a display to waiting customers.

3 and 4 show other embodiments of the present invention, and FIG. 3 corresponds to the circuit of the arrival warning lights 15 and 16 in FIG. 1, and the contact 3c and contact 1 in FIG.
Thyristors 17 and 18 connected in anti-parallel are inserted between 2b and 2b, and the DC power supplies (+) and (-) are changed to AC power supplies R and S. 19 is a car position detection device that emits an output corresponding to the car position; 2
0 is an ignition control device that controls the thyristors 17 and 18 by issuing an ignition signal according to the output of the car position detection device 19. Other than the above, the configuration is the same as in FIG. 1.

The thyristors 17 and 18 are controlled according to the car position, and a voltage that gradually increases according to the car position is applied to the arrival warning lights 15 and 16. That is, as explained in FIG. 1, the lighting time of the arrival forecast lights 15 and 16 is gradually decreased, and as shown in FIG. , 16 are gradually increased in brightness. This, in combination with the gradual decrease in the blinking period and the gradual increase in brightness, makes it possible to provide a display that gives a real sense to waiting customers.

Note that the above explanation applies after the car starts decelerating.
Arrival warning lights 15, 16 until the car arrives at the floor.
Although we have shown an example of a flashing service warning light, this can also be applied to elevators that use service warning lights. When a call is registered at a landing, the service warning light predicts the cars expected to be serviced on that floor based on traffic conditions and immediately displays the car at the landing, and the normal arrival warning lights 15 and 16 are used. be done. In this case, if it takes a long time to arrive at the floor after the service warning light is turned on, the lighting time is increased, for example, to 4 seconds, and gradually decreases to 3 seconds, 2 seconds, etc. as the person approaches the floor. This gives the waiting customers information that the car is approaching.
The feeling of frustration you feel before your basket arrives will be alleviated.

As explained above, in this invention, an uphill and a downhill forecast light is provided for each car at a landing where a plurality of cars are installed, and this forecast light is blinked to predict the arrival of a car, so that the car will arrive at the landing. The blinking period is shortened as the weather approaches, and furthermore, this blinking period shortening control is provided for both forecast lights for rising forecasts and descending forecasts, and is used in common.

Therefore, it is possible to visually display the approaching car to passengers at the landing area, and even if cars are predicted to arrive at the same landing area in different directions, it is possible to clearly display the situation, and to respond accordingly. This allows for smooth guidance of waiting customers. Furthermore, since the flashing cycle control for each of the upward and downward direction forecast lights is performed by one timer, the control apparatus can be simplified and an inexpensive arrival forecasting apparatus can be achieved.

Furthermore, in the present invention, not only the blinking period of the forecast lights but also the brightness is gradually increased.

Therefore, the combination of the gradual decrease in the blinking period and the gradual increase in brightness has the effect of providing a visually appealing display to passengers waiting in the hall.
