Description

  The present invention relates to an elevator with arrival guidance that emits a flashing lamp or chimes, sounds, etc. to a landing when the elevator car arrives at the landing.

  Passengers waiting for the elevator in the elevator hall often think that they arrived because they called the hall when they arrived from other floors, so as soon as the car arrived and the door opened Try to board. On the other hand, passengers in the car try to get off as soon as they arrive at the floor designated by their destination and the door opens. For this reason, if the passenger getting off the car and the passenger on the car are on the same floor, the passenger and the passenger may collide when the door is opened, or the passenger rushes and opens a passage. It often happened to do.

  Also, in order to prevent collision between passengers getting off from the car and waiting passengers at the landing, and to notify arrival so that safer services can be performed, there are customers who get off the car from the car and passengers who get on the car from the car Is present on the same floor, it is known that arrival guidance will be given when passengers get off in the car, that is, arrival guidance will be given at the timing of door opening completion after the landing door starts to open And Patent Documents 1 and 2.

JP 2004-067273 A JP 2010-254455 A

  The timing of arrival guidance described in the above-mentioned prior art patent documents does not take into account the congestion situation near the entrance / exit of the car, whether it is congested or empty near the entrance / exit of the car Arrival guidance is always made at the same timing. Therefore, depending on the congestion situation, there is a risk that smooth getting on and off may be hindered depending on the timing of arrival guidance, or passengers may get late. In particular, in the case of guidance after completion of getting off as in Patent Document 2, when the number of passengers is small and it is possible to get on and off at the same time, it is not efficient and the serviceability in operating the elevator is reduced. The waiting time at is longer.

  The object of the present invention is to solve the above-mentioned problems of the prior art, and to achieve smooth boarding / exiting even when the elevator passengers and the passengers are on the same floor with a simple configuration, and to reduce the passenger's delay. It is to suppress the occurrence and improve the serviceability of the elevator.

  In order to achieve the above object, the present invention is provided at the landing in an elevator with arrival guidance for performing arrival guidance to notify passengers waiting at the elevator landing that a car has arrived from another floor, A platform guidance device that provides the arrival guidance by flashing a lamp, or chime and sound, and the number of passengers that are installed in the platform or at the platform, and who enter the platform from the platform, and from the platform A passenger number detecting device for detecting the size of the number of people getting off at the landing and the completion of getting off, and a customer who gets off from the car to the landing and a customer who gets into the car from the landing are present on the same floor, When it is determined by the boarding / alighting number detection device that the number of people getting on and off is greater than a predetermined value, the car arrives on the same floor, By the landing guide device between Ri field from the door is beginning to open up to the completion of the drop-off is detected in which the arrival guidance is performed.

  According to the present invention, when it is determined that the passenger to get on and the passenger to get on are on the same floor and the number of people getting on and off is greater than a predetermined value, the time from when the landing door starts to open until completion of getting off is detected. As a result of the arrival guidance, a simple configuration ensures smooth boarding and unloading even when passengers and passengers are on the same floor, suppressing the occurrence of late arrivals and improving elevator serviceability. can do.

It is a figure which shows schematic structure of the elevator apparatus containing the elevator control apparatus of this embodiment. It is a figure which shows simply the arrival guidance by the elevator control apparatus of this embodiment. 3 is a control flowchart of arrival guidance shown in FIG. 2. It is a figure which shows simply the arrival guidance by the other example of the elevator control apparatus of this embodiment. It is a control flowchart of the arrival guidance shown in FIG. It is a figure which shows simply the arrival guidance by the other example of the elevator control apparatus of this embodiment. It is a control flowchart of the arrival guidance shown in FIG. It is a figure which shows simply the arrival guidance by the other example of the elevator control apparatus of this embodiment. FIG. 9 is a control flowchart of arrival guidance shown in FIG. 8.

  Conventional elevators are premised on giving arrival guidance to the passengers at the landing by chimes or blinking lights before the car arrives at the landing (for example, several seconds before) or before the door is opened. This arrival guide causes the passengers at the landing to be guided in front of the landing doors with the intention of getting into the car, and is a factor that hinders smooth getting on and off due to collisions between passengers and passengers. It has become.

  On the other hand, if there is no guidance to the passengers at the boarding point that the car has arrived, it is not preferable because there is a possibility that the car will be delayed without noticing that the car has arrived. This becomes more conspicuous as the number of cars increases as in a large-scale building, and the serviceability of the elevator is hindered.

  Hereinafter, embodiments of an elevator with arrival guidance will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of an elevator apparatus including an elevator control apparatus according to the present embodiment. The elevator device 100 includes an elevator car 1 and a car call registration device 2 that is provided in the car 1 and designates a destination floor of the car 1.

  The designation operation of the destination floor of the car 1 is performed by a car call registration button 3 provided in the car call registration device 2. In addition, an infrared sensor 4 is provided at a doorway of the car 1 as a boarding / alighting number detection device for detecting the size of passengers getting on and off from the car 1 and the number of passengers. For example, if the load detection device of the car 1 determines that the car load is large, the arrival guidance is delayed more than usual, and if there are many passengers passing through the infrared sensor 4 and the detection time is long, it is determined that the number of passengers getting off is large. However, arrival guidance is not performed until at least half of the passengers get off the predetermined value. If there are many passengers, the passengers who do not give arrival guidance until the completion of getting off can get on and off more smoothly without getting crowded at the boarding gate.

  The elevator device 100 also includes a landing call registration device 6 provided on the side of the landing door 5 of the elevator landing. The operation of calling the car 1 to the landing is performed by a landing call registration button 7 provided in the landing call registration device 6. In addition, in the vicinity of the upper end of the landing door 5 of the elevator landing, a landing guide device that informs waiting passengers at the landing of information such as which of the plurality of elevators is arriving and in which direction the elevator is heading. 8 is provided. For example, the platform guidance device 8 lights up when it is predicted that the car will land on the platform corresponding to the installation location according to the platform call.

  In the present embodiment, an example in which two upper and lower lamps (light emitting members) are used as the landing guide device 8 is shown, but other sounding members such as speakers that emit sound, chimes, and the like may be used. Moreover, it is good also as the hall guidance apparatus 8 combining both a light emission member and a sound generation member.

  The elevator apparatus 100 includes an elevator control apparatus 9 that performs arrival guidance for notifying a waiting customer at a landing that a car 1 has arrived from another floor. The elevator control device 9 includes a car call registration circuit 10 to which an output signal from the car call registration device 2 is input, a getting-off detection circuit 11 to which an output signal from the infrared sensor 4 is input, and a landing call registration device 6. There is a hall call registration circuit 12 to which an output signal is input.

  The car call registration circuit 10 receives destination floor data that is output when the car call registration button 3 of the car call registration device 2 is pressed. The getting-off detection circuit 11 receives the detection data of the passenger getting on and off by the infrared sensor 4. The landing call registration circuit 12 receives landing floor data that is output when a landing call registration button 7 provided in the landing call registration device 6 is pressed.

  The elevator control device 9 includes a timing setting circuit 13 that controls the timing of arrival guidance based on output signals from the car call registration circuit 10, the getting-off detection circuit 11, and the landing call registration circuit 12, and an output from the timing setting circuit 13. A guidance device control circuit 14 for controlling the guidance start / end timing of the platform guidance device 8 and the content of guidance based on the signal is provided.

  FIG. 2 is a diagram simply showing arrival guidance by the elevator control device 9. As shown in FIG. 2A, before the elevator arrives, there are a plurality of customers a in the car 1 descending from the upper floor, and the plurality of customers a are waiting for a plurality of customers b. Get off at the elevator platform waiting as a passenger. On the other hand, a plurality of customers b are waiting in the vicinity of the elevator landing door 5 where the landing guidance device is lit by reservation guidance by pressing the landing call registration button 7.

  Subsequently, as shown in FIG. 2B, arrival guidance is not performed when the car 1 arrives at the floor where a plurality of customers b are waiting. In the platform guidance device 8, the lamp lit in the reservation guidance is lit as it is, and flashing or the like is not performed. When the number of passengers a or b is large and the passengers cannot get on and off at the same time, as shown in FIG. 2C, the landing door 5 opens and a plurality of customers a get off.

  When it is detected based on the output signal from the infrared sensor 4 that all the passengers who have descended on this floor have finished descending, the lamp of the platform guidance device 8 blinks as shown in FIG. The blinking of the lamp by the platform guidance device 8 acts as a boarding guide that prompts the customer b who gets on the car 1 from the platform to get on the car 1, so that the customer b gets into the car 1. In addition, you may output a voice message such as “Please get on” from the speaker along with the blinking lamp of the platform guidance device 8, or “Please get on” from the speaker instead of the blinking lamp of the platform guidance device 8. May be output.

  FIG. 3 is a control flowchart of the elevator control apparatus when the reservation guide shown in FIG. 2 is performed. First, when it is set to perform reservation guidance, when the landing call registration button 7 is pressed, it is determined which elevator corresponds to the plurality of elevators, and the landing guide device 8 at a location corresponding to this determination is determined. The lamp is turned on to provide reservation guidance (step 1).

  The elevator (car 1) is about to arrive at the car call registration floor registered with the car call registration button 3 (step 2), and the landing registered with the hall call registration button 7 on the car call registration floor When call registration is detected (step 3), nothing is done as it is (without arrival guidance), and the elevator arrives (step 4). If it is detected that the passenger a getting off from the car 1 and the customer b getting on the car 1 from the landing are present on the same floor, the elevator arrives without doing anything as it is (without arrival guidance). This detection is performed by the timing setting circuit 13 based on whether signals from the car call registration circuit 10 and the landing call registration circuit 12 are duplicated on the same floor.

  When it is determined by the infrared sensor 4 that is the boarding / alighting number detection device that the number of boarding passengers on the floor is greater than a predetermined value, if it is detected that all passengers have got off the car 1 (step 5), the platform guidance device 8 Boarding guidance is performed by blinking the lamp (step 6).

  In the above, when the passenger who gets off the platform from the platform and the customer who gets on the platform from the platform are present on the same floor, the timing for performing the arrival guidance is changed depending on the number of passengers who get off or the number of passengers.

  In other words, if the number of passengers getting off or getting on board is greater than the predetermined value by shifting the timing of conventional arrival guidance that was performed several seconds before the car arrives at the landing or before opening the door, It will be delayed after it arrives and the door starts to open. According to this, since the waiting time at the landing is conscious of trying to get into the car at least after the door starts to open, it moves in front of the door before the landing door opens, preventing smooth getting on and off Can be avoided. Also, when you try to move in front of the landing door by arrival guidance, you can see that passengers are getting off from the car, so you can get on and off smoothly without moving to a place that gets in the way of getting off can do. In this way, smooth control of getting on and off when the elevator passenger and the passenger are on the same floor can be realized by simple control of shifting the timing of arrival guidance.

  In addition, if there are many people getting on and off, it can act as a boarding guide that prompts passengers to get into the car from the boarding by performing arrival guidance after the door of the boarding starts to open, Occurrence of passenger delays can be suppressed. Furthermore, when the number of people getting on and off is less than a predetermined value, it is possible to get on and off at almost the same time by providing arrival guidance, for example, a few seconds before the car arrives at the landing, or before opening the door, as before. You can get on and off.

  If the number of passengers getting off or getting on is more than a predetermined value, the arrival guidance is not performed before the car 1 arrives or before the landing door 5 opens, so that the customer b is guided in front of the landing door 5 and stops at the landing door. Attempts to get into the car 1 at the same time that 5 opens can be suppressed. As a result, smooth boarding / alighting can be achieved. In addition, since the arrival guidance timing is delayed to act as boarding guidance, it is possible to suppress the occurrence of a situation in which the customer b is delayed without noticing that the car has arrived.

  The infrared sensor 4 can detect whether or not a passenger has passed through the landing door 5, but cannot determine whether or not all the passengers have exited. However, if a preset threshold time (for example, several hundred ms to several s) elapses after detecting the passage of a certain customer's door, it may be determined that all passengers on that floor have finished getting off.

  In addition, a video camera that captures the inside of the car 1 is provided, and a moving image output from the video camera is processed to obtain a motion vector of the customer near the entrance of the car. Based on the magnitude of the motion vector, it is determined whether the number of people getting off, the completion of getting off, or the size of the number of passengers.

  Furthermore, when the arrival floor of the car 1 is reserved and registered using an IC card, the number of passengers on that floor can be determined based on the amount of change in the load in the car. In other words, in recent years, a reader that reads information registered in an IC card is installed at the entrance of a building or an elevator platform, and the IC card assigned to each passenger is placed over the reader in advance and registered in that IC card. There is a service in which the destination floor of an elevator is automatically reserved and registered based on the existing information. Therefore, using the IC card service, for example, the destination floor is reserved and registered using the IC card, the number of passengers is determined based on the number of reservations registered, and after the car 1 arrives at the destination floor, the load of the car 1 The amount of change (increase) can be obtained, and the number of people who got off the floor or the magnitude of the arrival can be estimated based on the value.

  Furthermore, after the car 1 arrives at the reserved floor, if the infrared sensor detects the estimated number of passing doors, it can be determined that all passengers on that floor have finished getting off. In addition, after the car 1 arrives at the reserved floor without using the infrared sensor, if a decrease equivalent to the increase in the load on the car 1 is detected, it may be determined that all passengers on that floor have finished getting off. it can.

4 is a diagram schematically showing arrival guidance according to another example. 4A and 4B are the same as FIG. 2A and FIG. 2B, so description thereof is omitted.
In this example, as shown in FIG. 4C, the lamp of the landing guide device 8 is blinked at the moment when the car 1 arrives at the landing and the landing door 5 starts to open or immediately after it starts to open. Then, the customer b tries to move to the front of the landing door 5 by being guided by the blinking lamp of the landing guidance device 8. However, since the customer a getting off from the landing door 5 enters the field of view, the customer b does not actually move in front of the landing door 5, and the customer a gets off smoothly. Subsequently, as shown in FIG. 4D, the customer b enters the car 1 after confirming that all the customers have finished getting off. In addition, you may output a voice message such as “Please get on” from the speaker along with the blinking lamp of the platform guidance device 8, or “Please get on” from the speaker instead of the blinking lamp of the platform guidance device 8. May be output.

  FIG. 5 is a control flowchart in the case of performing the reservation guide shown in FIG. Steps 11 to 14 are the same as steps 1 to 4 in the flowchart shown in FIG. In this example, when it is detected that the landing door 5 starts to open (step 15), boarding guidance is performed by blinking the lamp of the landing guide device 8 (step 16).

  As shown in FIG. 2 to FIG. 5, at least the car 1 arrives at a different timing, for example, several seconds before the car 1 arrives at the landing or before the door is opened. This delays after the landing door 5 starts to open. According to this, the timing at which the consciousness of getting into the car 1 is generated at least after the landing door 5 starts to open, so that the landing door 5 moves in front of the landing door 5 before the landing door 5 opens. Can prevent the smooth getting on and off.

  In addition, this arrival guide acts as a boarding guide that gives a consciousness of getting into the car 1 to the waiting customer b at the landing place by delaying the timing. For example, as shown in FIG. 4, when the car 1 arrives at the landing and the landing door 5 starts to open or immediately after starting to open, the user tries to move to the front of the landing door 5 by the boarding guidance. Sometimes, it can be seen that the passenger a starts to get off from the car 1, so that it is not necessary to move to a place where it gets in the way of getting off, and smooth getting on and off can be realized. In this way, smooth control of getting on and off when the elevator passenger and the passenger are on the same floor can be realized by simple control of shifting the timing of arrival guidance.

  If the elevator passenger and the passenger do not exist on the same floor, the arrival guidance may be provided, for example, a few seconds before the car 1 arrives at the landing, as in the past, as shown in FIGS. As shown, the arrival guidance timing may be delayed.

  FIG. 6 is a diagram simply showing arrival guidance according to another example. This example shows the arrival guidance of the elevator control apparatus when reservation guidance is not performed. First, as shown in FIG. 6 (A), there is a customer a in the car 1 descending from the upper floor, and this customer a is at the elevator platform where the customer b is waiting as a waiting customer. Get off. On the other hand, customer b is pressing the landing call registration button 7 but reservation guidance is not made, so it is not possible to know which elevator car 1 of a plurality of elevators will arrive, and waits at a position relatively far from the landing door 5. doing.

  Subsequently, as shown in FIG. 6B, arrival guidance is not performed when the car 1 arrives at the floor where the customer b waits. In other words, nothing is lit on the lamps of the platform guidance device 8.

Subsequently, as shown in FIG. 6C, the landing door 5 opens and the customer a gets off. Then, as shown in FIG. 6 (D), when it is detected based on the output signal from the infrared sensor 4 that all the passengers who have descended on this floor have been descended, the lamp of the landing guide device 8 is blinked. The blinking of the lamp by the platform guidance device 8 acts as a boarding guide that prompts the customer b who gets on the car 1 from the platform to get on the car 1, so that the customer b gets into the car 1.
In addition, you may output a voice message such as “Please get on” from the speaker along with the blinking lamp of the platform guidance device 8, or “Please get on” from the speaker instead of the blinking lamp of the platform guidance device 8. May be output.

  FIG. 7 is a control flowchart when the reservation guidance shown in FIG. 6 is not performed. First, the elevator (car 1) is about to arrive at the car call registration floor registered by the car call registration button 3 (step 21), and is registered at the car call registration floor by the landing call registration button 7. If the landing call registration is detected (step 22), nothing is done as it is (without arrival guidance), and the elevator arrives (step 23).

  Subsequently, when it is detected by the infrared sensor 4 that is a boarding / exiting number detection device that the passengers get off at the floor is large (step 24), the lamp of the platform guidance device 8 is blinked. Boarding guidance is provided (step 25).

  Thus, even if the reservation guidance is not performed, the arrival guidance is not performed before the car 1 arrives or before the landing door 5 opens, so that the customer b is guided in front of the landing door 5 and the landing Attempting to get into the car 1 at the same time as the door 5 opens can be suppressed. As a result, smooth boarding / alighting can be achieved. In addition, since the arrival guidance timing is delayed to act as boarding guidance, it is possible to suppress the occurrence of a situation in which the customer b is delayed without noticing that the car has arrived.

  In the examples shown in FIGS. 6 and 7, the boarding guidance is performed when all the passengers get off at the floor in the car 1, but the present invention is not limited to this, but as explained in FIGS. 4 and 6. At the moment when the car 1 arrives at the landing and the landing door 5 starts to open, or when the landing door 5 starts to open, the lamp of the landing guide device 8 may be blinked immediately to provide boarding guidance.

  FIG. 8 is a diagram simply showing arrival guidance according to still another example. Since FIG. 8A is similar to FIG. 7A, description thereof is omitted. In this example, as shown in FIG. 8B, the lamp of the platform guidance device 8 is turned on, for example, several seconds before or when the car 1 arrives at the platform. In this way, by notifying the customer b of the location where the car 1 arrives, the customer b standing at a position relatively away from the landing door 5 is guided to the vicinity of the landing door 5 to some extent.

  Subsequently, as shown in FIG. 8C, the landing door 5 opens and the customer a gets off. Then, as shown in FIG. 8 (D), when it is detected based on the output signal from the infrared sensor 4 that all the passengers who have descended on this floor have been detected, the lamp of the landing guide device 8 is blinked. The blinking of the lamp by the platform guidance device 8 acts as a boarding guide that prompts the customer b who gets on the car 1 from the platform to get on the car 1, so that the customer b gets into the car 1.

  FIG. 9 is a control flowchart when the reservation guidance shown in FIG. 8 is not performed. First, the elevator (car 1) is about to arrive at the car call registration floor registered by the car call registration button 3 (step 31), and is registered at the car call registration floor by the landing call registration button 7. If the landing call registration is detected (step 32), the lamp of the landing guidance device 8 is turned on to guide the customer b to the vicinity of the landing door 5 to some extent (step 33).

  Subsequently, when the elevator arrives (step 34) and it is detected by the infrared sensor 4 which is a boarding / alighting number detection device that all passengers on the floor have got off the car 1 (step 35), the landing guide device 8 Boarding guidance is provided by blinking the lamp (step 36).

  According to this, since the arrival location of the car 1 can be notified by the lighting of the lamp of the hall guidance device 8 before the arrival of the car 1, the customer b who is waiting at a position relatively away from the hall door 5b. Can be guided to the vicinity of the landing door 5 to some extent. At this timing, the lamp of the platform guidance device 8 is not blinked or voice guidance is provided, so that the customer b does not recognize that the platform door 5 will be opened immediately and moves to the front of the platform door 5. Or trying to get into the car 1 at the same time as the landing door 5 opens. As a result, smooth boarding / alighting can be achieved.

Also, if you do not provide reservation guidance, you do not know where the elevator will arrive, so you will not notice that the car has arrived, or you will notice that the landing door 5 will be closed when you are heading to the car There is also a risk of being late. This becomes more conspicuous as the number of cars increases as in a large-scale building. In this regard, by indicating the arrival location of the car 1 by turning on the lamp of the boarding guidance device 8 before the arrival of the car 1, the passenger b waiting at a position relatively away from the landing door 5 is given to the landing door to some extent. Since it can guide to 5 near, it can control that the boarding delay to car 1 occurs.

  In the example shown in FIGS. 8 and 9, the boarding guidance is provided when all passengers get off at the floor in the car 1, but the present invention is not limited to this, but as described in FIGS. 4 and 5. Alternatively, when the car 1 arrives at the landing and the landing door 5 starts to open, or immediately after the landing door 5 starts to open, the lamp of the landing guide device 8 may blink to provide boarding guidance.
