Description

[Detailed Description of the Invention] This invention selects and allocates a service car from among a plurality of cars in response to a landing call, displays a forecast guide to that effect at the landing, and displays an arrival display to indicate that the car has arrived. The present invention relates to an improvement of an elevator notification device as described above.

When multiple elevators are installed in parallel, normal group management operation is performed. One of these group management methods is the assignment method, which improves operational efficiency by allocating a car to be serviced immediately when a hall call is registered, and allowing only the assigned car to respond to the hall call. and shorten waiting time.

In addition, in group-controlled elevators using such an allocation system, hall lanterns are generally provided for each floor, each car, and each direction, and these display information (hereinafter referred to as a forecast display) of the allocated car to passengers waiting at the landing. , a guidance display (hereinafter referred to as arrival display) is displayed upon arrival.

FIGS. 1 and 2 are for explaining a conventional control circuit for a hall lantern that performs elevator car forecasting and arrival display.

Figure 1 shows the arrival display command circuit for the upbound hall lantern of car A. 1 is an AND gate, which contains the upbound direction signal uA, which becomes "H" when the car is running in the upbound direction, and the decision to stop the car. When the door is closed, the signal becomes "H", and after the door is stopped, the door opens, the door starts closing again, and when the door is closed, it becomes "L".The stop command signal ST is input, and the logical product is established. At this time, an uplink arrival display command signal HLU is sent.

Figure 2 shows the control circuit for the hall lantern in the ascending direction of the third floor of Unit A, with 2 and 3 representing NOT gates, 4,
5 is an OR gate, 6 and 7 are AND gates,
An up hall lantern 3uHA on the third floor is connected to the output side of the OR gate 5.

In the circuit configured as described above, consider the case where car A leaves the first floor and stops in response to an up call from the third floor.

Assume that when car A is on the first floor, an up call for the third floor is registered, and car A is assigned to the up call for the third floor. At this time, the 3rd floor up forecast signal 3uA becomes "H", the 3rd floor car position signal 3A becomes "L", and the output of NOT gate 3 becomes "H" and the output of OR gate 4 becomes "H".
The output of the AND gate 6, which has the output of the OR gate 4 and the 3rd floor up forecast signal 3uA as two inputs, becomes "H", and accordingly the output of the OR gate 5 also becomes "H", giving a lighting command to the hall lantern 3uAH. give,
Light up the 3uHA lantern in the upward direction hall on the 3rd floor to display the forecast for the assigned car.

As a result, the passengers waiting in the upward direction on the third floor know that the service car is in Car A and wait in front of the landing of Car A.

Next, when car A leaves the first floor and arrives at the third floor, a stop command is issued, and the stop command signal ST becomes "H", and the output of AND gate 1, that is, the upstream arrival display command signal HLU, becomes "H". becomes. Accordingly, the output of the NOT gate 2 shown in FIG. 2 becomes "L" and the third floor car position signal 3A becomes "H", so the output of the NOT gate 3 also becomes "L", so the OR
The output of gate 4 becomes "L", the output of AND gate 6 becomes "L", and the forecast display based on the third floor upstream forecast signal 3uA is cut off.

On the other hand, since the upstream arrival display command signal HLU and the 3rd floor car position signal 3A are both "H", the periodic pulse signal PLS (pulse for hall lantern blinking that repeats "H" and "L" every 0.5 seconds) is becomes “H”,
At the same time, the output of OR gate 5 also becomes "H" and lights up the hall lantern 3uHA on the third floor. Furthermore, when the periodic pulse signal PLS becomes "L", the outputs of the AND gate 7 and OR gate 5 are inverted and become "L", turning off the hall lantern 3uHA. That is,
The up hall lantern 3uHA on the third floor will be blinked at 0.5 second intervals by the periodic pulse signal PLS.

The arrival display by flashing hall lanterns allows passengers waiting at the landing to know that the car has arrived. The door of the car opens on the floor, and after the passenger has boarded and alighted, the door starts closing. When the door is completely closed, the stop command signal ST becomes "L", and the upbound arrival display command signal HLU is set to "L" by the AND gate 1. The output of the AND gate 7 also becomes "L", and the hall lantern stops blinking and goes out. Note that the 3rd floor inbound forecast signal 3uA is reversed to "L" when the 3rd floor inbound call is answered by Unit A and the door of Unit A opens, indicating that the door has been closed. At this point, the output of the AND gate 6 has already become "L".

Furthermore, when Car A departs from the 1st floor and stops only in response to a car call on the 3rd floor, the 3rd floor ascending forecast signal 3uA is "L", so the output of the AND gate 6 is "L". Therefore, the hall lantern 3uHA will not light up until the A vehicle decides to stop on the third floor and the upbound arrival display command signal HLU becomes "H". When the upbound arrival display command signal HLU becomes "H", the hall lantern is blinked until just before the car departs from the third floor, as described above.

In this way, since the forecast display provides guidance before the arrival of the service car, passengers waiting at the landing have the advantage of being able to safely wait in front of the car displaying the forecast.

However, since calls occur randomly, the predicted car may not always arrive first, and it is possible that a non-forecast car may respond to a car call and arrive before the predicted car. . In this case as well, the arrival display is performed in the same way as in the forecast basket. Therefore, when an unforecasted car arrives slightly before the forecasted car, passengers waiting in front of the forecasted car are lured by the arrival display of the unforecasted car and begin to move in the direction of that car. . However, as the forecast cars arrived soon, passengers were confused as to which car to board, causing confusion at the boarding area.
In addition, passengers were sometimes boarded separately for cars that had not been forecasted and cars that had been forecasted, which was not desirable in terms of transportation efficiency. In order to avoid reducing transportation efficiency, a method has been proposed in which no arrival display is displayed at all even if a car that has not been predicted arrives first. There is a good chance that this will not be noticed, which is not a good thing in terms of passenger service when the forecast car arrives after a considerable delay.

In addition, by predicting the order of arrival at the boarding area, for example, 1
The first-come, first-served car is the second car expected to arrive.
Even if the car that is expected to arrive first is displayed as the next car at the landing, the predicted arrival order may be incorrect and the next car may arrive first. This may cause confusion for waiting customers.

This invention solves the above-mentioned drawbacks, and when a car that has not been forecasted arrives before the forecast car, the arrival display of the car that has not been forecasted is made different from normal depending on the predicted arrival status of the forecast car. To provide an elevator notification device which does not cause confusion to waiting passengers at a landing.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 3 shows an example of an arrival display command circuit for an elevator notification device according to the present invention when three cars, A to C, are installed in parallel.
is an expected arrival time calculation device, and this calculation device 8
From now on, if this is used for the landing on the third floor in the upward direction,
When the expected arrival time signals 3uTA, 3uTB, 3uTC, XO, YO, and ZO are all "L", a large (300 seconds) expected arrival time signal will be selectively output until reaching the third floor in the upward direction. ing.

The output signal (estimated arrival time signal) 9a sent from the selection circuit 9 is applied to a comparator 10 and compared with a constant value signal T (=5 seconds).When the output signal 9a is a constant value signal, the comparator 10 The output of 10 becomes "H", representing the arrival display restriction signal 10a. In addition, since the output signal 10a of the comparator 10 becomes "L" when there is no forecast car, an arrival indication is sent out when the stop decision is made, and these signals 3uTA, 3
uTB and 3uTC are input to terminals X ₁ , Y ₁ , and Z ₁ of the selection circuit 9. In addition, the input terminals X ₀ , Y ₀ , Z ₀ of the selection circuit 9 are connected to the A machine, the B machine,
Forecast signals going up to the 3rd floor of Unit C 3uA, 3uB, 3uC,
are respectively input, and when the input terminal X ₀ = "H", the expected arrival time signal 3uTA is selected and output, and when the input terminal Y ₀ = "H",
Estimated arrival time signal 3uTB is input terminal Z ₀ = “H”
At this time, the expected arrival time signal 3uTC is selectively outputted and switched to the input terminal.

The output signal 10a of the comparator 10 is input as one input to the OR gate 14 via the NOT gate 11, and the forecast signal 3uA of the third order is added to the OR gate 14. 15 has two inputs, the output of the above OR gate 14 and the stop signal ST.
AND gate, 16 is the output of AND gate 15,
This is an OR gate that has three inputs: the door open/close command signal CLS, which is inverted by the NOT gate 12, and the door close switch signal GS, which is inverted by the NOT gate 13.The output of this OR gate 16 is The upstream direction signal uA, which becomes "H" when the signal is reached, is applied as the other input to an AND gate 1 which has one input as the other input, and the upstream arrival display command signal HLU is sent from this AND gate 1.

The door opening/closing command signal CLS is "H" when closing the car door, and "L" when opening the door. In addition, the door close switch signal GS is generated from a switch installed on the car door, and is "H" when the door is closed and "L" when the door is open.
It is something that becomes.

Next, the operation of the hall lantern of the present invention will be explained with reference to FIGS. 2 and 3.

(i) When car A is assigned to the up call for the 3rd floor Before the car of car A decides to stop in the upbound direction on the 3rd floor, as described in the conventional example, the hall lantern 3
uHA is lit. Also, car A is 3.
When it is decided to stop on the floor, the stop command signal ST becomes "H"
becomes. Since the third floor up forecast signal 3uA is "H", the output of the OR gate 14 becomes "H", and accordingly, the AND gate 1
The output of 5 becomes "H". When the output of the AND gate 15 becomes "H", the output of the OR gate 16 becomes "H", and this output and the upstream signal uA=
Due to "H", the output of AND gate 1 becomes "H" and the hall lantern 3uHA is completely destroyed.

(ii) When Car A is stopped in the up direction in response to a car call on the 3rd floor (in this case, it is assumed that Car B is assigned to the up call on the 3rd floor).
The hall lantern 3uHA was off before the car of Unit A decided to stop on the way up to the 3rd floor.

Here, when the car of car A decides to stop on the 3rd floor due to a car call, the result of the calculation processing in the calculation device 8 is the expected arrival time signal 3uTA = 0 seconds for car A to the 3rd floor upbound landing, and the car Estimated arrival time signal 3uTB = 10 seconds to the 3rd floor upbound landing, Estimated arrival time signal 3 to the 3rd floor upbound landing of Unit C
Assuming that uTC=20 seconds, in the selection circuit 9,
Since the 3rd floor up forecast signal 3uB of Unit B is “H”, the predicted arrival time signal of Unit B is 3uTB.
Select and output.

The expected arrival time of this selected output signal 9a is
Since it is 10 seconds, when the comparator 10 compares it with the constant value signal T (=5 seconds), the output signal 9a becomes greater than the constant value signal, and as a result, the output of the comparator 10 becomes "L". As a result, the output of NOT gate 11 becomes "H", the output of OR gate 14 also becomes "H",
Further, due to the OR gate 14 and the stop command signal "H", the output of the AND gate 15 becomes "H", and the output of the OR gate 16 which receives this output also becomes "H". The output of OR gate 16 is “H”
Then, the output HLU of the AND gate 1 whose other input is the upstream signal "H" becomes "H", and if this "H" output is input to the AND gate 7 shown in FIG. 2, the synchronization pulse signal When PLS is added to AND gate 7, the hall lantern 3uHA blinks.

Also, when the car of Unit A decided to stop on the 3rd floor,
Estimated arrival time to the 3rd floor upbound platform for Cars A, B, and C processed by calculation device 8 is 3
Assuming that uTA = 0 seconds, 3uTB = 2 seconds, and 3uTC = 20 seconds, in the selection circuit 9, since the forecast signal 3uB is "H", the expected arrival time signal 3 of aircraft B
uTB is selected and outputs an output signal 9a=2 seconds. When this output signal 9a=2 seconds is compared with the constant value signal T (=5 seconds) in the comparator 10,
Since the signal 9a is signal T, the output of the comparator 10 becomes "H", and accordingly, the output of the NOT gate 11 becomes "L", so the output of the AND gate 1 becomes "L", and as a result, the hall lantern 3uHA
remains off.

On the other hand, when the No. 3 forecast car is decided to stop approximately 2 seconds later, the hall lantern of No. B, which is controlled by a circuit similar to that shown in FIG. 2, starts blinking, although not shown.

In addition, when the car of car A starts opening the door after stopping, the door opening/closing command signal CLS becomes "L", so
When the output of NOT gate 12 becomes "H" and the output of OR gate 16 becomes "H", the output HLU of AND gate 1 becomes "H" due to this and "H" of uplink signal uA. At the same time as the doors began to open, the hall lantern 3uHA began blinking, later than the arrival display of Unit B. After that, when the boarding and alighting of car A is completed and the door starts closing, the door opening/closing command CLS becomes "H", which causes NOT
The output of gate 12 becomes "L", but since the door close switch signal GS becomes "L", NOT gate 13
The output of becomes “H”, and accordingly OR gate 1
The output of 6 becomes "H". Therefore, during the door closing operation, the output HLU of the AND gate 1 is held at "H" and the hall lantern 3uHA continues to blink.
When door closing is completed, the door close switch signal GS becomes "H", so the output of NOT gate 13 becomes "L", and the output of OR gate 16 also becomes "L".
As a result, the output HLU of AND gate 1 is set to "L", thereby turning off the hall lantern 3uHA.

In the above embodiment, when the predicted car is likely to arrive within a predetermined time, the arrival display of the unforeseen car that arrived earlier due to the car call is delayed until the door opens, not when the stop decision is made. As a result, passengers can be guided to the forecast car without causing confusion among passengers waiting at the platform.

In addition, in the above embodiment, the time of the constant value signal T was set to 5 seconds, but this time was determined by taking into consideration the time from the decision to stop to the start of opening the door, and it may be set shorter than this. Well, as long as there is no time for passengers waiting at the boarding point to get lost, you can set it a little longer.

Furthermore, although the arrival display for cars that have not been forecasted has been delayed until the door begins to open, the extent to which the arrival display is delayed is not limited to this, and the arrival display start time depends on the size of the predicted arrival time of the forecasted car. It's okay to be late. Further, when it is predicted that the predicted car will arrive within the predetermined time T, the arrival display of the car that is not predicted may not be displayed. In this case, there will be no confusion among passengers.

Further, in the above embodiment, the arrival display is visually performed by flashing hall lanterns, but this can also be applied to an audible display by sounding a gong, chime, or the like. In this case, the notification method will be more likely to attract the attention of passengers waiting at the boarding point.
The effects of this invention can be further improved.

FIG. 4 shows another embodiment of this invention.
Parts with the same reference numerals as in FIG. 3 represent the same components as in FIG _{. 3} , and _the difference from FIG. ₃ is that the input terminals In place of the 3rd floor up forecast signal in the case shown, Unit A~
First-arrival signal 31uA, 31uB, 3 on the 3rd floor of Unit C
The point is that 1uC is added to each. The first-arrival signals 31uA to 31uC become "H" only for the car that is guided and displayed as the first-arrival car.

In this embodiment, the arrival order of the cars at the landing is predicted, and for example, the first-arriving car (the first car to arrive), the second-arriving car (the second car to arrive), etc.
can be displayed in sequence. In this case, the first-arriving car can be made to correspond to the predicted car, and the next-arriving car can be made to correspond to the car for which the forecast has not been made. In addition, the arrival order is first-come, first-served.
This is effective when displaying details such as 2nd place, 3rd place, 4th place, etc.

In addition, in the case where the above-mentioned guidance display is performed, if a situation occurs in which the next arriving car (for example, car B) arrives earlier than the predicted first arriving car (for example, car A), the next car will be displayed. Prohibit display of arrival. Alternatively, if the first car is predicted to arrive within the predetermined time T, it is possible to display the arrival of the next car later than usual.

As described above, according to the present invention, in a system that displays a forecast of assigned cars at a landing or a guidance display of the arrival order of cars at a landing, a car that is not predicted to arrive before the predicted car due to an error in the prediction. The arrival display of unforeseen cars is displayed differently depending on the predicted arrival status of the forecasted cars, so there is no confusion among waiting passengers at the landing, and the transport efficiency of elevators is improved. Favorable passenger service is possible without deterioration.
