Description

The present invention relates to an elevator door control device.

If the brightness of the elevator car and the landing on each floor are different, when the car arrives at the floor and the door opens, the passengers in the car will suddenly brighten or darken the surroundings. Exposed to change. Then, passengers in the car, especially those who are near the door and immediately descend to the floor, take time for their vision to adapt to changes in illuminance, so-called light or dark adaptation, so for a while, It becomes difficult to see the floor of the floor that is about to get off, other passengers waiting, etc. For this reason, passengers may find it difficult to see the step in the traveling direction and other passengers, and may delay the start of the disembarkation operation. If the passengers are delayed, it takes time for the passengers to get on and off, which leads to a decrease in the efficiency of elevator operation.

As a technique for alleviating the problem based on the difference in illuminance between the illuminance in the elevator car and the illuminance on the floor as described above, for example, Patent Document 1 describes the illuminance in the car and the illuminance on the arriving floor. It is disclosed that the illuminance in the car is adjusted to match the illuminance of the landing on the floor by adjusting the brightness of the lighting device in the car before the car arrives at the floor so that the difference is small.

JP-A-2007-84228

As described above, if the illuminance in the car is matched with the illuminance of the landing so that the difference between the illuminance in the car and the illuminance of the landing on the arriving floor becomes small, for example, the illuminance of the landing on the extremely dark arrival floor Dimming the lights in the car to match the conditions will provide an inconvenient illuminance environment where passengers cannot see the surroundings from the time they are in the car, and it is sufficient to photograph the inside of the car with a surveillance camera. It may not be possible to obtain a clear brightness. Further, when the brightness in the car is required to be above a certain level due to regulations or the like, the above-mentioned prior art cannot be applied. In addition, if the landing on the next destination floor is bright, the inside of the car will suddenly brighten from a dark state.

In this way, brightening or darkening the inside of the car will frequently require passengers who continue to ride in the car to adjust their vision, instead of promoting the visual adaptation of passengers descending from the car to the floor. There was a challenge.

The present invention has been made to solve the above problems, and in a lighting environment that provides brightness in the car so as not to impair the convenience of the user in the car, the inside of the elevator car and the illuminance. It is an object of the present invention to provide an elevator door control device that can promote smooth visual adaptation to users who get off the landing on floors with different floors.

The door control device for an elevator according to the present invention includes an illuminance difference calculation unit that calculates an illuminance difference between the illuminance in the elevator car and the illuminance of the landing on the floor, and a door opening speed corresponding to the calculated illuminance difference. The door opening speed determination unit is provided with a door opening speed determination unit, and the door opening speed determination unit determines a speed slower than the door opening speed corresponding to an illuminance difference smaller than the illuminance difference calculated by the illuminance difference calculation unit as the door opening speed. However, the drive device that opens and closes the door is controlled according to the determined door opening speed.

In the door control device for the elevator according to the present invention, the door opening speed corresponding to the illuminance difference between the illuminance in the car and the illuminance on the floor is smaller than the detected illuminance difference. Since the speed is determined to be slower than the opening speed, the larger the illuminance difference between the illuminance in the car and the illuminance on the floor, the slower the door will open, so the illuminance in the car will be gentle on the floor. By approaching the illuminance of, it is possible to encourage the user to smoothly adapt to the visual image.

Embodiment 1.
Hereinafter, the elevator door control device according to the embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view schematically showing a machine room 1, a car 2, and a landing 3 of an elevator system in which an elevator door control device according to the first embodiment of the present invention is installed. The operation of the car 2 is controlled by the elevator control device 4 installed in the machine room 1 to move back and forth between the floors, and FIG. 1 shows a state in which the car 2 has arrived at the landing 3 on any floor.

This elevator is provided with a door that opens and closes when the car 2 arrives at each floor. Specifically, the elevator door consists of a car side door 5a provided in the car 2 and a landing side door 5b provided in the landing 3, and each time the car 2 arrives at the landing 3, the car side door 5a And the landing side door 5b opens together so that passengers can get on and off. The opening and closing of the car side door 5a and the landing side door 5b is also controlled by the elevator control device 4.

Further, in the elevator to which the present invention is applied, an illuminance meter 6a in the car for detecting the illuminance in the car 2 of the elevator is provided on the wall surface in the car 2, and further, a landing 3 on the floor where the car 2 arrives. A landing illuminance meter 6b for detecting the illuminance of the above is provided on the wall surface of the landing 3 on each floor. The height at which the landing illuminance meter 6b and the illuminance meter 6a in the car are installed is less affected by the shadow of the user 7 when measuring the illuminance, and can detect the illuminance as close as possible to the illuminance felt by the user 7. The position is desirable, for example, it is installed at a height similar to the height of the line of sight of the user 7. The landing illuminance meter 6b is installed on all floors where the elevator car 2 stops, but the illuminance must be the same, for example, all floors are under the same type of lighting in the building. If is known in advance, it may be installed only on a specific floor.

In such an elevator, when the user 7 who gets into the elevator car 2 specifies the destination floor with the destination floor button or the like, the elevator control device 4 controls the operation of the elevator car 2 and moves the elevator to the destination floor. When the elevator car 2 arrives at the floor of the destination floor, the elevator control device 4 opens the elevator car side door 5a and the landing side door 5b.

Then, in this embodiment, the door control device of the present invention provided in the elevator control device 4 acquires the illuminance detected by the in-car illuminance meter 6a and the landing illuminance meter 6b, respectively, and according to this illuminance difference, The speed at which the car side door 5a and the landing side door 5b are opened when the car 2 arrives at the floor is determined. The door opening speed corresponding to this illuminance difference is determined to be a standard speed when the illuminance difference is small, and to be slower than the standard door opening speed when the illuminance difference is large. That is, the door opening speed corresponding to the illuminance difference obtained by actually measuring the illuminance in the elevator car 2 and the landing 3 is determined to be slower than the door opening speed when the illuminance difference is smaller than the illuminance difference. Will be done. As a result, the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the slower the door opens. Therefore, the illuminance in the car gradually approaches the illuminance of the landing, and the passengers can feel the illuminance. On the other hand, smooth visual adaptation can be promoted.

Next, a detailed configuration of the elevator door control device of the present embodiment will be described. FIG. 2 is a configuration diagram showing a detailed configuration of an elevator system in which the elevator door control device of the first embodiment of the present invention is installed.

As shown in FIG. 2, the car 2 is provided with a communication unit 9a connected to the network 8. The illuminance in the car 2 detected by the ilometer 6a in the car is sent to the elevator control device 4 via the communication unit 9a, and the door opening / closing control signal sent from the elevator control device 4 drives the door to open / close. The drive device 10 is transmitted to the drive device 10 to open and close the car side door 5a and the landing side door 5b according to the control signal received from the elevator control device 4.

Further, the landing 3 is provided with a communication unit 9b connected to the network 8. The illuminance of the landing 3 measured by the landing illuminance meter 6b is sent to the elevator control device 4 via the communication unit 9b.

Next, the configuration of the elevator control device 4 will be described.

The communication unit 9c is connected to the network 8 and communicates with the communication unit 9a of the elevator car 2 and the communication unit 9b of the landing 3 via the network 8.

The elevator control unit 11 receives information from the elevator car 2 and the landing 3, and controls the operation of the elevator such as running control of the elevator car 2 and the elevator car 2 at the landing 3.

The door control device 12 controls the opening and closing of the car side door 5a and the landing side door 5b based on the information from the elevator car 2 and the landing 3, and the car interior illuminance acquisition unit 13 and the landing illuminance acquisition unit 13. It is composed of 14, an illuminance difference calculation unit 15, a door opening speed determination unit 16, and a door opening / closing control unit 17.

The illuminance acquisition unit 13 in the car acquires the illuminance in the car detected by the illuminance meter 6a in the car via the communication unit 9a and the communication unit 9c, and the illuminance acquisition unit 14 is obtained by the illuminance meter 6b in the landing 3 on each floor. The detected illuminance of the landing 3 is acquired via the communication unit 9b and the communication unit 9c.

The illuminance difference calculation unit 15 calculates the illuminance difference between the illuminance in the elevator car 2 acquired by the illuminance acquisition unit 13 in the car and the illuminance of the landing 3 acquired by the illuminance acquisition unit 14.

The door opening speed determination unit 16 determines the door opening speed at which the car side door 5a and the landing side door 5b are opened based on the illuminance difference calculated by the illuminance difference calculation unit 15. When determining the door opening speed, a speed slower than the door opening speed corresponding to the illuminance difference smaller than the illuminance difference calculated by the illuminance difference calculation unit 15 is determined as the door opening speed. That is, the door opening speed is determined so that the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the slower the door opens.

Specifically, the door opening speed determination unit 16 includes a door opening speed storage unit 161 and a door opening speed selection unit 162. The door opening speed storage unit 161 stores a door opening speed table showing the door opening speed corresponding to the difference in illuminance. FIG. 3 is an example of a door opening speed table stored by the door opening speed storage unit 161. The door opening speed is set slower as the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2 increases. .. In the example of FIG. 3, the door opening speed V1 corresponding to the illuminance difference of 0 to 500 lp, which has the smallest illuminance difference among the door opening speed tables, corresponds to the standard door opening speed of the elevator to be applied, and the largest illuminance difference of 5000 lux or more. The door opening speed V4 is set to half the door opening speed V1, and the door opening speed V2 and V3 corresponding to the difference in illuminance between them are the door opening speeds between the door opening speed V1 and the door opening speed V4. The speed is set. The door opening speed selection unit 162 receives information on the illuminance difference from the illuminance difference calculation unit 15, and selects the door opening speed corresponding to the illuminance difference from the door opening speed table stored in the door opening speed storage unit 161. It is determined and this is transmitted to the door opening / closing control unit 17.

The configuration and method for determining the door opening speed are not limited to this. For example, instead of the door opening speed storage unit 161 and the door opening speed selection unit 162, a function for determining the door opening speed using the illuminance difference as a parameter is used. A means for calculating the door opening speed may be provided, and the speed obtained by applying the illuminance difference calculated by the illuminance difference calculation unit 15 to this function may be determined as the door opening speed. That is, if the door opening speed is determined to be a speed corresponding to the illuminance difference and the speed becomes slower as the illuminance difference is larger, it may be determined by another configuration or method.

The door opening / closing control unit 17 controls the drive device 10 that drives the door to open / close according to the door opening speed determined by the door opening speed determining unit 16.
The door fully open time determination unit 18 determines the door fully open time for maintaining the fully open state after the door is fully opened. The door fully open time determination unit 18 includes a door fully open time storage unit 181 and a door fully open time selection unit 182. The door fully open time storage unit 181 stores a door fully open time table showing the door fully open time corresponding to the illuminance difference. FIG. 4 is an example of the door fully open time table stored by the door fully open time storage unit 181. The door fully open time is set as the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2 increases. Has been done. In the example of FIG. 4, the standard door full-open time of the elevator applied to the door full-open time T1 corresponding to the illuminance difference of 0 to 500 lp, which is the smallest in the door full-open time table, corresponds to the largest illuminance difference of 5000 lp or more. The door full-open time T4 is set to twice the door full-open time T1, and the door full-open time T2 and T3 corresponding to the difference in illuminance between them are the door open time between the door full-open time T1 and the door full-open time T4. The speed is set. The door opening speed selection unit 162 receives information on the illuminance difference from the illuminance difference calculation unit 15, and selects the door full opening time corresponding to the illuminance difference from the door full opening time table stored in the door full opening time storage unit 181. The door full opening time is determined, and this is notified to the door opening / closing control unit 17.
The door opening / closing control unit 17 controls the drive device 10 for opening / closing the door according to the door opening speed determined by the door opening speed determining unit 16 as described above, and when the door is fully opened, the door opening / closing time determining unit 18 determines. The drive device 10 is controlled so that the door is closed after the determined full opening time of the door has elapsed.

However, the time when the door is fully opened may be extended if the door opening should be extended, such as when the operation buttons in the car 2 or the landing 3 are operated.

Next, the operation of the elevator control device 4 of the present embodiment will be described. FIG. 5 is a flowchart showing the operation of the elevator control device 4 of the first embodiment. When this elevator starts operation, the elevator control unit 11 controls the operation of the car 2 in step S100, and the car 2 is operated. The elevator control unit 11 monitors whether the elevating car 2 has arrived at the destination floor in step S101, and when it detects that the car 2 has arrived at the destination floor, notifies the door control device 12 that the detection has been detected. To do.

Upon receiving the notification that the car 2 has arrived at the destination floor, the door control device 12 performs the door opening / closing operation after step S102. In step S101, the operation of the door control device 12 may be started as soon as possible by monitoring whether the car 2 has arrived at the target floor but soon.

In the door control device 12, first, the illuminance in the car detected by the illuminance meter 6a in the car in step S102 is acquired by the illuminance acquisition unit 13 in the car, and the illuminance of the landing 3 on the arriving floor detected by the illuminance meter 6b is obtained. The landing illuminance acquisition unit 14 acquires it.

Then, the process proceeds to step S103, and the illuminance difference calculation unit 15 calculates the illuminance difference between the illuminance in the elevator car 2 acquired by the illuminance acquisition unit 13 in the car and the illuminance in the landing 3 acquired by the illuminance acquisition unit 14. To do.

Subsequently, in step S104, the door opening speed determination unit 16 determines the door opening speed at which the car side door 5a and the landing side door 5b are opened based on the illuminance difference calculated by the illuminance difference calculation unit 15. The door opening speed selection unit 162 receives information on the illuminance difference from the illuminance difference calculation unit 15, selects the door opening speed stored in the door opening speed storage unit 161 corresponding to the illuminance difference, and causes the door opening / closing control unit 17 to select the door opening speed. Tell. Further, in step S104, the door full-open time determination unit 18 determines the door full-open time based on the illuminance difference calculated by the illuminance difference calculation unit 15 and informs the door open / close control unit 17.

Then, the process proceeds to step S105, and the door opening / closing control unit 17 controls the drive device 10 according to the door opening speed determined by the door opening speed determining unit 16 in step S104. As a result, the drive device 10 drives the car side door 5a and the landing side door 5b at the door opening speed determined by the door opening speed determining unit 16, respectively, and the door is opened.

After the door is fully opened, in step S106, the door open / close control unit 17 maintains the fully open state for the door fully open time determined by the door fully open time determination unit 18 in step S104, and drives the door to close after the lapse of the fully open time. 10 is controlled.

However, the time when the door is fully opened may be extended if the door opening should be extended, such as when the operation buttons in the car 2 or the landing 3 are operated.

Then, after the door is closed in step S106, the process returns to step S100 to control the operation of the car 2 by the elevator control unit 11, and in step S101, it is monitored whether the car 2 has arrived at the next destination floor, and the car 2 is used. Repeats the above operation when the player arrives at the destination floor.

FIG. 6 shows an example of a change in the opening / closing speed of the door with the passage of time when the door is opened / closed using the door control device of the first embodiment. When the illuminance difference between the car 2 and the landing 3 is 0 to 500 lux, the door opening speed determination unit 16 selects V1, which is the door opening speed during standard operation of this elevator, as the door opening speed this time. Then, as shown by the solid line W1 in FIG. 6, the door opening speed gradually accelerates from the initial speed 0 to reach V1, and the door continues to open at this door opening speed V1. When the opening of the door reaches a predetermined opening slightly before the full opening, the door opening speed starts to decelerate, and just before the full opening, the door opens once at a low constant speed and finally reaches the fully opened state.
Further, during the door fully open time T1 determined by the door fully open time determination unit 18, the fully open state is maintained, and then the door closing operation is started, and when the door is closed, the door opening speed is V1 and the door closing control is performed in the same manner. Will be done.

When the illuminance difference between the car 2 and the landing 3 is 500 to 1000 lux, the door opening speed determination unit 16 determines the door opening speed of the door corresponding to an illuminance difference of 0 to 500 lux smaller than the detected illuminance difference. V2, which is slower than V1, which is the opening speed, is selected. Then, as shown by the broken line W2 in FIG. 6, the door opening speed gradually accelerates from the initial speed 0 to reach V2, the door continues to open at this door opening speed V2, and the door opens more slowly than when the solid line W1. To do. After that, when the opening of the door reaches a predetermined opening slightly before the full opening, the door opening speed starts to decelerate, and just before the full opening, the door opens once at a low constant speed and finally reaches the fully opened state.
Further, in the case of this illuminance difference of 500 to 1000 lp, the door full-open time T2, which is longer than the door full-open time T1 corresponding to the illuminance difference of 0 to 500 lux, is determined as the door full-open time. As a result, after the door reaches the fully open state, it is maintained in the fully open state for a long time during the door fully open time T2, and then shifts to the door closing operation, and when the door is closed, the door opening speed V2 determined earlier Instead, the door is closed and controlled at the door opening speed V1 during standard operation of the elevator. Even when the door is closed, the door may be closed at the door opening speed V2, but the door closing speed is irrelevant to the user who got out of the car, and the user who continues to ride in the car and the user who got in the car Since slowing the door closing speed has little effect on visual adaptation, it is better to close the door earlier if the operation of the car 2 is to be accelerated.

As shown in FIG. 6, the door opens more slowly in the case of the broken line W2 in which the illuminance difference is 500 to 1000 lp than in the case of the solid line W1 in which the illuminance difference of the landing 3 is 0 to 500 lux. As the illuminance gradually approaches the illuminance of the landing, it is possible to encourage passengers to smoothly adjust their vision. Further, since the time in the fully open state is longer in the case of the broken line W2 having an illuminance difference of 500 to 1000 lux than in the case of the solid line W1 having an illuminance difference of 0 to 500 lux, the illuminance of the landing 3 and the inside of the elevator car 2 When the illuminance difference from the illuminance of is large, it takes a long time for the passenger to adapt to light or dark.

As described above, in the first embodiment of the present invention, the door opening speed determining unit 16 determines the door opening speed so that the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the slower the door opening speed. .. That is, the door opening speed determination unit 16 determines as the door opening speed a speed slower than the door opening speed corresponding to the illuminance difference smaller than the illuminance difference calculated by the illuminance difference calculation unit 15. As a result, the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the slower the door opens. Therefore, when the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2 is large. By gradually approaching the illuminance of the landing in the car, it is possible to encourage passengers to adjust their vision smoothly, and when the illuminance difference is small, the door opens moderately quickly and the user Efficient boarding and alighting can be promoted.

Further, the door full opening time determination unit 18 determines the door full opening time so that the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the longer. That is, the door full-open time determination unit 18 determines as the door full-open time a time longer than the door full-open time corresponding to the illuminance difference smaller than the illuminance difference calculated by the illuminance difference calculation unit 15. As a result, the larger the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2, the longer the time when the door is fully opened. For this reason, when the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2 is large, it takes a long time for the passenger to adapt to light or dark, so that the passenger can afford to adapt to light or dark. You can get off after you have it.

Embodiment 2.
In the first embodiment, the door opening control is performed by setting the determined door opening speed as the fastest speed, but if the passenger's visual adaptation can be promoted at the initial stage of the door opening, then the standard speed is used. You may open the door. In the second embodiment, an example will be described in which the door opening control is first performed at the determined door opening speed, and then the door opening speed is increased to accelerate the start of getting on and off the user. The configuration of the elevator door control device of the second embodiment is the same as that shown in the first embodiment.
FIG. 7 is a flowchart showing the operation of the elevator control device according to the second embodiment, and in steps S200 to S205 of FIG. 7, the same operation as S100 to S105 of FIG. 5 is performed.

In the second embodiment, in step S206, the door opening / closing control unit 17 monitors whether a predetermined time has elapsed since the door opening was started. If the predetermined time has not elapsed, the process returns to step S205, and the door opening operation is continued at the determined door opening speed.

FIG. 8 shows a change in the opening / closing speed of the door with the passage of time when the door is opened / closed using the door control device of the second embodiment. The solid line W1 in FIG. 8 refers to the door opening speed table of FIG. 3 in step S204, and as a result, when the illuminance difference is 0 to 500 lux and the door opening speed is determined to be V1, the broken line W3 shows the illuminance difference in step S204. The cases where the door opening speed V4 is determined at 5000 lx or more are shown respectively.

If it is determined in step S206 that the predetermined time td has elapsed, the process proceeds to step S207, and the door opening speed is set to a speed faster than V4, for example, V1 which is the door opening speed during standard operation of this elevator, and based on this V1. The door opens to the fully open state. As shown in FIG. 8, when the illuminance difference is 0 to 500 lp, the door opening speed is V1 from the beginning, so the operation is based on V1 as it is, and the operation is the same as that in FIG. On the other hand, when the illuminance difference is 5000 lx or more, the door opening speed is changed from V4 to V1 as shown by the broken line W3 after the lapse of the predetermined time td, and the door opening speed is increased.
After that, when the door is fully opened, the process proceeds to step S208, the door is opened for the set door full opening time, and the process returns to step S200.

As described above, when the difference in illuminance is large, the operating efficiency of the elevator is improved by encouraging the user to visually adjust the door slowly at a predetermined time and opening the door quickly after the predetermined time has elapsed. be able to.

According to the second embodiment as described above, the door opening / closing control unit 17 monitors whether a predetermined time has elapsed since the door opening started, and initially controls the door opening at a determined door opening speed, and the predetermined time elapses. After that, by speeding up the door opening speed and accelerating the start of boarding and alighting of the user, the door opening speed is accelerated after slowing down the change in illuminance, so the illuminance in the car is gradually brought closer to the illuminance of the landing on the floor, and the elevator Operation efficiency can be improved.

Embodiment 3.
In the first embodiment, the door opening control is performed based on the door opening speed once determined. However, since the illuminance difference changes as the illuminance in the car 2 changes during the door opening, the door opening The door opening speed may be appropriately changed according to the difference in illuminance. In the third embodiment, an example of controlling the door opening while appropriately determining and changing the door opening speed even during the door opening will be described. The configuration of the elevator door control device according to the third embodiment of the present invention is the same as that shown in the first embodiment.
FIG. 9 is a flowchart showing the operation of the elevator control device according to the third embodiment. In steps S300 to S305 of FIG. 9, the same operation as in S100 to S105 of FIG. 5 is performed.
In the third embodiment, after the door opening is started at the door opening speed determined in step S305, the door opening / closing control unit 17 monitors whether the door is fully opened in step S306 at a constant cycle. If a certain period of time has passed and the car is not fully opened, the process returns to step S302 to acquire the latest illuminance in the car 2 and the illuminance of the landing 3. Then, the illuminance difference is calculated in step S303 using the acquired illuminance, the door opening speed and the door opening time are determined, and the door is opened again at the door opening speed calculated in step S305.

When the door is opened and closed using the door control device of the third embodiment, the illuminance difference between the inside of the car 2 and the landing 3 changes as the door opens, so that the door opens following the change. The speed can be changed. For example, when the door opening speed is calculated and determined using a function that determines the door opening speed using the illuminance difference as a variable, the door opening speed becomes faster as the door opens.

As described above, in the third embodiment of the present invention, the door opening / closing control unit 17 monitors whether the door is fully opened in step S306, acquires illuminance as appropriate, and re-opens the door according to the illuminance difference. By setting, the illuminance change is slowed down, and as the illuminance difference decreases, the illuminance speed increases as the door opens, so the elevator operation is performed while gradually bringing the illuminance in the car closer to the illuminance of the landing on the floor. Efficiency can be improved.
In the above embodiment, when determining the door opening speed, as shown in the example of the door opening speed table in FIG. 3, the illuminance difference between the illuminance of the landing 3 and the illuminance in the elevator car 2 is dealt with. We have explained what determines one speed, but you may decide multiple door opening speeds at once. For example, various door opening speed patterns can be set by determining a change pattern of the door opening speed including a plurality of door opening speeds with respect to the illuminance difference once calculated.
