Description

Elevator door control device

This invention relates to an elevator door control device.

If the elevators in the elevator and the floors of the floors are different in brightness, when the car arrives at the floor and the door is opened, passengers in the car will have an illuminance that the surroundings suddenly become brighter or suddenly darken. Exposed to change. Then, passengers in the car, especially passengers who are close to the door and immediately get down to the floor, take time to adjust to the changes in illumination, so-called light adaptation or dark adaptation, so for a while, It becomes difficult to see the floor of the floor about to get off and other passengers waiting. For this reason, the passenger feels it is difficult to confirm the level difference in the traveling direction and other passengers, and there is a possibility that the start of the operation of getting off is delayed. If a passenger's operation is delayed, it takes time for passengers to get on and off, which leads to a decrease in the efficiency of elevator operation.

As a technique for reducing the problem based on the difference in illuminance between the elevator car and the floor landing as described above, for example, Patent Literature 1 describes the difference between the illuminance in the car and the illuminance of the landing floor. In order to reduce the difference, there is disclosed a technique in which the luminance of the lighting device in the car is adjusted before the car arrives at the floor so that the illuminance in the car is matched with the illuminance of the hall on the floor.

JP 2007-84228 A

As described above, in order to reduce the difference between the illuminance in the car and the illuminance on the arrival floor, the illuminance on the arrival floor is very dark. If the lighting in the car is darkened to match the situation, it will provide an inconvenient illuminance environment where passengers can not see the surroundings from when they are in the car, and it is sufficient for photographing the inside of the car with a surveillance camera There is a possibility that the brightness is not obtained. Furthermore, the above-mentioned prior art cannot be applied when the brightness in the car is required to be a certain level or more due to regulations or the like. In addition, when the hall on the next destination floor is bright, the car is suddenly brightened from a dark state.

In this way, lightening or darkening the car will require frequent visual adaptation for passengers who continue to ride in the car, instead of encouraging the passengers to go to the floor from the car. There was a problem.

The present invention has been made to solve the above-described problems. In an illumination environment that provides brightness in a car that does not impair the convenience of users in the car, the interior of the elevator car and illuminance are provided. It is an object of the present invention to provide an elevator door control device capable of prompting a user who gets off to a landing on a floor with a difference in smooth visual adaptation.

The elevator door control device according to the present invention includes an illuminance difference calculating unit that calculates an illuminance difference between the illuminance in the elevator car and the illuminance on the floor, and a door opening speed corresponding to the calculated illuminance difference. The door opening speed determination unit determines 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 as the door opening speed. Then, the drive device for opening and closing the door is controlled according to the determined door opening speed.

In the elevator door control device according to the present invention, the door corresponding to the illuminance difference smaller than the illuminance difference obtained by detecting the illuminance difference between the illuminance in the car and the illuminance on the floor landing. Since the speed is determined to be slower than the opening speed, the door opens more slowly as the illuminance difference between the illuminance in the car and the illuminance on the floor floor increases, so the illuminance in the car gradually becomes lower. By approaching the illuminance, it is possible to prompt the user to adapt smoothly.

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

FIG. 1 is a schematic diagram schematically showing a machine room 1, a car 2, and a landing 3 of an elevator system in which the elevator door control device according to Embodiment 1 of the present invention is installed. Operation of the car 2 is controlled by an elevator control device 4 installed in the machine room 1, and the car 2 moves back and forth between the floors. FIG. 1 shows a state in which the car 2 arrives at the landing 3 on an arbitrary floor.

This elevator has a door that opens and closes when the car 2 arrives at each floor. This elevator door is specifically composed of a car side door 5a provided in the car 2 and a landing side door 5b provided in the hall 3, and each time the car 2 arrives at the hall 3, the car side door 5a. And the landing side door 5b opens together, and passengers can get on and off. The elevator control device 4 controls the opening and closing of the car side door 5a and the landing side door 5b.

In the elevator to which the present invention is applied, an in-car illuminance meter 6a for detecting the illuminance in the car 2 of the elevator is provided on the wall surface in the car 2, and further, the floor platform 3 where the car 2 arrives. A hall illuminometer 6b is provided on the wall surface of the hall 3 on each floor. The height at which the hall illuminance meter 6b and the in-car illuminance meter 6a 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, and for example, it is installed at a height approximately equal to the height of the user 7's line of sight. The hall illuminance meter 6b is installed in all floor halls where the elevator car 2 stops, but all floor halls are under the same type of lighting in the building, and the illuminance is equal. May be installed only on a specific floor.

In such an elevator, when a user 7 who has entered the elevator car 2 designates a destination floor with a destination floor button or the like, the elevator control device 4 performs control to operate the elevator car 2 and moves it to the destination floor. When the elevator car 2 arrives at the destination floor, the elevator controller 4 opens the elevator car side door 5a and the landing side door 5b.

And in this embodiment, the door control device of the present invention provided in the elevator control device 4 acquires the illuminance detected by the car illuminometer 6a and the hall illuminometer 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 as a standard speed when the illuminance difference is small, and is determined 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. Is done. As the illuminance difference between the illuminance at the hall 3 and the illuminance in the elevator car 2 increases, the door opens more slowly. Therefore, the illuminance in the car gradually approaches the illuminance at the hall. It is possible to promote smooth visual adaptation.

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 the elevator system in which the elevator door control device according to the first embodiment of the present invention is installed.

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

In addition, the hall 3 is provided with a communication unit 9b connected to the network 8. The illuminance of the hall 3 measured by the hall illuminometer 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 hall 3 via the network 8.

The elevator control unit 11 receives information from the elevator car 2 and the hall 3 and performs elevator operation control such as travel control of the elevator car 2 and the elevator car 2 at the hall 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 information from the elevator car 2 and the landing 3, and an in-car illuminance acquisition unit 13 and a landing illuminance acquisition unit. 14, an illuminance difference calculation unit 15, a door opening speed determination unit 16, and a door opening / closing control unit 17.

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

The door opening speed determination unit 16 determines the opening speed of the car side door 5a and the landing side door 5b to open 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 calculating unit 15 is determined as the door opening speed. That is, the door opening speed is determined so that the door opens more slowly as the difference in illuminance between the illuminance at the hall 3 and the illuminance in the elevator car 2 increases.

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 memory | storage part 161 memorize | stores the door opening speed table which shows the door opening speed corresponding to an illuminance difference. FIG. 3 is an example of a door opening speed table stored in the door opening speed storage unit 161. The door opening speed is set to be slower as the illuminance difference between the illuminance at the landing 3 and the illuminance within the elevator car 2 increases. . In the example of FIG. 3, the door opening speed V1 corresponding to the illuminance difference 0 to 500 lx having the smallest illuminance difference in the door opening speed table corresponds to the standard door opening speed of the elevator to be applied and the largest illuminance difference of 5000 lx or more. The door opening speed V4 is set to half the door opening speed V1, and the door opening speeds V2 and V3 corresponding to the illuminance difference between them are the door opening speed V1 and the door opening speed V4. 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 a door opening speed corresponding to the illuminance difference from the door opening speed table stored in the door opening speed storage unit 161. This is determined and 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 an 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 calculating unit 15 to this function may be determined as the door opening speed. That is, the door opening speed may be determined by another configuration and method as long as the door opening speed is determined to be a speed corresponding to the illuminance difference and a slower speed as the illuminance difference is larger.

The door opening / closing control unit 17 controls the driving device 10 that opens and closes the door according to the door opening speed determined by the door opening speed determination unit 16.
After the door is fully opened, the door fully open time determination unit 18 determines the door fully open time for maintaining the fully open state. The door full open time determination unit 18 includes a door full open time storage unit 181 and a door full open time selection unit 182. The door full open time storage unit 181 stores a door full open time table indicating the door full open time corresponding to the illuminance difference. FIG. 4 is an example of a door full open time table stored in the door full open time storage unit 181. The door full open time is set to be longer as the illuminance difference between the illuminance at the hall 3 and the illuminance within the elevator car 2 increases. Has been. In the example of FIG. 4, the door full open time T1 corresponding to the illuminance difference 0 to 500 lx with the smallest illuminance difference in the door full open time table corresponds to the standard door full open time of the elevator to be applied, the largest illuminance difference of 5000 lx or more. The door full open time T4 is set to be double the door full open time T1, and the door full open times T2 and T3 corresponding to the difference in illuminance between them are the door open times between the door full open time T1 and the door full open time T4. 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 fully open time is determined and this is transmitted to the door opening / closing control unit 17.
The door opening / closing control unit 17 controls the drive device 10 that opens and closes the door according to the door opening speed determined by the door opening speed determination unit 16 as described above. When the door is fully opened, the door full opening time determination unit 18 The drive device 10 is controlled so that the door is closed after the determined full opening time of the door.

However, the time during which the door is fully opened may be extended when the door opening should be extended, such as when the operation buttons of the car 2 and the hall 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 according to the first embodiment. When the elevator starts operation, the elevator control unit 11 controls the operation of the car 2 in step S100, and the car 2 is operated. In step S101, the elevator control unit 11 monitors whether the car 2 being lifted / lowered has arrived at the destination floor, and when detecting that the car 2 has arrived at the destination floor, notifies the door control device 12 of the detection. To do.

The door control device 12 that has received the notification that the car 2 has arrived at the destination floor performs the door opening / closing operation after step S102. In step S101, the operation of the door control device 12 may be started earlier by monitoring whether the car 2 arrives at the destination floor, not 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 arrival floor 3 detected by the landing illuminance meter 6b is obtained. The hall illuminance acquisition unit 14 acquires.

Then, it progresses to step S103 and the illuminance difference calculation part 15 calculates the illuminance difference between the illuminance in the elevator car 2 acquired by the in-car illuminance acquisition part 13 and the illuminance of the hall 3 acquired by the landing illuminance acquisition part 14. To do.

Subsequently, in step S104, the door opening speed determining unit 16 determines the door opening speed for opening the car side door 5a and the landing side door 5b based on the illuminance difference calculated by the illuminance difference calculating unit 15. The door opening speed selection unit 162 receives the information of 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 sends it to the door opening / closing control unit 17. Tell. In step S <b> 104, 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 notifies the door open / close control unit 17.

And it progresses to step S105 and the door opening / closing control part 17 controls the drive device 10 according to the door opening speed which the door opening speed determination part 16 determined by step S104. Thereby, 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 determination unit 16, respectively, and the door is opened.

After the door is fully opened, in step S106, the door opening and closing control unit 17 maintains the fully opened state for the door fully opened time determined by the door fully opened time determining unit 18 in step S104, and the drive device is configured to close the door after the fully opened time has elapsed. 10 is controlled.

Then, after the door is closed in step S106, the operation returns to step S100 and the elevator controller 11 controls the operation of the car 2. In step S101, it is monitored whether the car 2 has arrived at the next destination floor. Repeat the above operations when arrives at the destination floor.

FIG. 6 shows an example of a change in the door opening / closing speed with the passage of time when the door is opened and closed using the door control device of the first embodiment. When the difference in illuminance between the car 2 and the hall 3 is 0 to 500 lx, the door opening speed determining unit 16 selects V1 that is the door opening speed during the standard operation of the elevator as the current door opening speed. Then, as shown by the solid line W1 in FIG. 6, the door opening speed is first accelerated gradually from the initial speed 0 to reach V1, and the door continues to open at this door opening speed V1. When the opening degree of the door reaches a predetermined opening degree slightly before the full opening, the door opening speed starts to decelerate, and immediately before the full opening, the door is opened at a constant low speed and finally reaches the full opening state.
Further, the door fully open state is maintained during the door fully open time T1 determined by the door fully open time determining unit 18, and then the door closing operation is performed, and the door closing speed V1 is also used when the door is closed. Is done.

When the difference in illuminance between the car 2 and the hall 3 is 500 to 1000 lx, the door opening speed determination unit 16 causes the door corresponding to an illuminance difference 0 to 500 lx smaller than the detected illuminance difference as the current door opening speed. V2 that is slower than V1 that is the opening speed is selected. Then, as shown by the broken line W2 in FIG. 6, the door opening speed first accelerates gradually from the initial speed 0 to reach V2, and the door continues to open at this door opening speed V2 and opens more slowly than in the case of the solid line W1. To do. Thereafter, when the opening degree of the door reaches a predetermined opening degree slightly before the full opening, the door opening speed starts to decelerate, and the door is opened at a constant low speed just before the full opening, and finally the full opening state is reached.
In the case of the illuminance difference of 500 to 1000 lx, a door full open time T2 longer than the door full open time T1 corresponding to the illuminance difference of 0 to 500 lx is determined as the door full open time. As a result, after the door reaches the fully open state, the door is kept fully open during the door fully open time T2, and then the door shift operation is started. When the door is closed, the door opening speed V2 previously determined. Instead, the door closing control is performed at the door opening speed V1 during the standard operation of the elevator. Even when the door is closed, the door closing operation may be performed at the door opening speed V2. However, the door closing speed is irrelevant for the user who gets off the car, and the user who has continued to ride in the car, Since slowing down 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 accelerated.

As shown in FIG. 6, the door opens more slowly in the case of the broken line W2 where the illuminance difference is 500 to 1000 lx than in the case of the solid line W1 where the illuminance difference of the hall 3 is 0 to 500 lx. As the illuminance gradually approaches the illuminance at the hall, passengers can be encouraged to smoothly adapt to their vision. Furthermore, the time in the fully open state is longer in the case of the broken line W2 with the illuminance difference of 500 to 1000 lx than in the case of the solid line W1 with the illuminance difference of 0 to 500 lx. When the illuminance difference from the illuminance 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 door opening speed becomes slower as the difference in illuminance between the illuminance at the hall 3 and the illuminance in the elevator car 2 increases. . That is, the door opening speed determining unit 16 determines a door opening speed that is slower than the door opening speed corresponding to the illuminance difference smaller than the illuminance difference calculated by the illuminance difference calculating unit 15. As a result, the door opens more slowly as the illuminance difference between the illuminance at the hall 3 and the illuminance in the elevator car 2 increases, and therefore the illuminance difference between the illuminance at the hall 3 and the illuminance in the elevator car 2 is large. The illuminance in the car slowly approaches the illuminance at the hall, so that passengers can be smoothly adapted to visual adaptation. When the illuminance difference is small, the door can be opened reasonably quickly. Efficient boarding / exiting can be promoted.

Also, the door full opening time determination unit 18 determines the door full opening time so that the longer the difference in illuminance between the illuminance at the hall 3 and the illuminance within the elevator car 2, the longer it is. That is, the door full open time determination unit 18 determines 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 the door full open time. Thus, the longer the illuminance difference between the illuminance at the hall 3 and the illuminance within the elevator car 2 is, the longer the time during which the door is fully opened. For this reason, when the illuminance difference between the illuminance at the hall 3 and the illuminance in the elevator car 2 is large, the passenger needs more time for light adaptation or dark adaptation. You can get off after you have it.

Embodiment 2.
In the first embodiment, the door opening speed determined is set to be the fastest speed and the door opening control is performed. However, if the passenger's visual adaptation can be promoted at the initial stage of the door opening, then the standard opening speed is used. You may open the door. In the second embodiment, an example will be described in which door opening control is initially performed at the determined door opening speed, and then the door opening speed is increased to speed up the user's start of getting on and off. 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 apparatus according to the second embodiment. In steps S200 to S205 in FIG. 7, the same operations as in S100 to S105 in FIG. 5 are performed.

In the second embodiment, it is monitored in step S206 whether a predetermined time has elapsed since the door opening / closing control unit 17 started the door opening. 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 over time when the door is opened / closed using the door control device of the second embodiment. The solid line W1 in FIG. 8 indicates that the illuminance difference is 0 to 500 lx and the door opening speed is determined to be V1 as a result of referring to the door opening speed table in FIG. The case where the door opening speed V4 is determined at 5000 lx or more is shown.

If it is determined in step S206 that the predetermined time td has elapsed, the process proceeds to step S207, where the door opening speed is set to a speed higher than V4, for example, V1 which is the door opening speed during standard operation of the elevator, and based on this V1 Open to full open. As shown in FIG. 8, when the illuminance difference is 0 to 500 lx, since the door opening speed is V1 from the beginning, the operation is based on V1 as it is, and the operation is the same as 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 predetermined time td has elapsed, and the door opening speed is increased.
Thereafter, when the door is fully opened, the process proceeds to step S208, the door is opened for the set door fully open time, and the process returns to step S200.

As described above, when the illuminance difference is large, the user's visual adaptation is encouraged in a predetermined time when the door is slowly opened, and the door is opened quickly after the predetermined time has elapsed, thereby improving the operation efficiency of the elevator. be able to.

According to the second embodiment as described above, it is monitored whether a predetermined time has elapsed since the door opening / closing control unit 17 started the door opening, and the door opening control is initially performed at the determined door opening speed, and the predetermined time has elapsed. After that, by speeding up the door opening speed and accelerating the start of boarding / exiting the user, the door opening speed is increased after slowing down the illuminance change. The driving efficiency can be improved.

Embodiment 3.
Although Embodiment 1 explained what performs door opening control based on the door opening speed once determined, since the illuminance difference also changes as the illuminance in the car 2 changes during the door opening, You may make it change a door opening speed suitably according to an illumination intensity difference. In the third embodiment, an example of performing door opening control while appropriately determining and changing the door opening speed even during 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 apparatus according to the third embodiment. In steps S300 to S305 in FIG. 9, operations similar to those in steps S100 to S105 in FIG. 5 are performed.
In the third embodiment, after the door opening is started at the door opening speed determined in step S305, it is monitored in step S306 whether the door opening / closing control unit 17 has fully opened the door at a constant cycle. If the predetermined time has elapsed and the door has not been fully opened, the process returns to step S302, and the illuminance of the latest car 2 and the hall 3 is acquired. Then, using the acquired illuminance, the illuminance difference is calculated in step S303, the door opening speed and the door opening time are determined, and the door is opened at the door opening speed calculated again in step S305.

When the door is opened and closed using the door control device of the third embodiment, as the door opens, the difference in illuminance between the car 2 and the landing 3 changes. 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 increases as the door opens.

As described above, in Embodiment 3 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 reopens the door opening speed according to the illuminance difference. With this setting, the door opening speed increases as the illuminance difference decreases as the door opening progresses while slowing down the illuminance change, so the elevator can be operated while gently bringing the illuminance in the car closer to the illuminance on the floor. Efficiency can be improved.
In the above embodiment, when the door opening speed is determined, as shown in the example of the door opening speed table in FIG. 3, one corresponding to the illuminance difference between the illuminance at the landing 3 and the illuminance in the elevator car 2. Although what determines one speed was demonstrated, you may make it determine several 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 calculated once.
