Description

  Embodiments of the present invention relate to an elevator power saving system that shuts off the power supply of each device according to the operation demand of the elevator.

  In buildings such as condominiums, when there is little demand for elevator operation, the operation of the elevator is suspended, and the group management system performs power saving operation such as reducing the number of operations. However, even if the elevator is stopped, power is consumed because each device of the elevator is energized.

  Therefore, the power supply of each device is cut off to a standby state according to the operation demand of the elevator, and when the user operates the hall call button, the power of each device is turned on to return to the normal operation.

  However, even if the device is turned on when the user operates the hall call button, each device does not immediately start to operate, so the driving service cannot be resumed for a while. May be mistaken for a failure.

  Therefore, there is a need for an elevator power saving system that can smoothly return from the power saving mode to the normal operation mode when a user comes to the landing.

  The power saving system of the elevator according to the present embodiment is set by the power saving mode setting means for setting the power saving mode by cutting off the power supply of each device according to the operation demand of the elevator, and the power saving mode setting means. User detection means for detecting in advance the user who came to the landing during the power saving mode, and when the user is detected by the user detection means, the above devices are turned on and the normal operation mode is set. And a return control means for performing return control to.

  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram illustrating a configuration of an elevator power saving system according to the first embodiment. A main rope 12 is wound around the hoisting machine 11, and a car 13 is attached to one end of the main rope 12, and a counterweight 14 is attached to the other end. When the hoisting machine 11 is driven, the car 13 and the counterweight 14 move in a slidable manner via the main rope 12.

  A destination floor registration button 15 for registering a destination floor is provided in the car 13. A hall call button 16 for registering an upward or downward hall call is provided at the hall on each floor. These buttons 15 and 16 are connected to the elevator control device 22 via the transmission cable 17.

  The drive device 21 is a device that receives the drive command from the elevator control device 22 and drives the hoisting machine 11, and includes a converter, an inverter, and the like (not shown).

  When the hall call is registered by operating the hall call button 16, the elevator control device 22 causes the car 13 to respond to the registration floor of the hall call and operates the destination floor registration button 15 in the car 13 to operate the destination. When the floor is registered, operation control such as moving the car 13 to the destination floor is performed.

  In addition, as a function for realizing the present system, the elevator control device 22 shuts off the power of each device 23 including the drive device 21 according to the operation demand of the elevator (the car 13), thereby saving power. A power saving mode setting function for setting the user, a user detection function for detecting a user who has come to the landing during the power saving mode in advance, and each device 23 including the drive device 21 when a user is detected. And a return control function for turning on the power and performing return control to the normal operation mode.

  “Each device 23” shown in FIG. 1 refers to devices other than the drive device 21 that operate by receiving required power. Specifically, “doors”, “lights in a car”, “cars” Such as “inside indicator”, “inside car calling device”, and “landing indicator”.

  The “door” is a door provided in the car 13. “In-car lighting” is lighting equipment installed on the ceiling or the like in the car 13. The “in-car display” is a display device for displaying the current car position and driving direction in the car 13. The “car calling device” includes a destination floor registration button 15 in the car 13 and its response lamp. The “landing display” is a display device for displaying the current car position, driving direction, and the like at the landing.

  Here, in 1st Embodiment, the security door 24 is used as a user detection means for detecting a user in advance in a hall.

  The security door 24 is also called “entrance lock”, and is installed at the landing as one of the security systems linked to the elevator in a building such as an apartment. In the example of FIG. 1, it is installed at the landing on the first floor, which is the reference floor. The security door 24 is normally in a state in which the lock mechanism is activated, and the user releases the lock mechanism by inputting a personal identification number or reading information on a security card possessed by the user. The security door 24 is connected to the elevator control device 22, and when the lock mechanism is released by the user, the release signal is given to the elevator control device 22.

Next, the operation of this system will be described.
FIG. 2 is a flowchart showing the processing operation of the elevator control device 22 of the present system.

  The elevator control device 22 monitors the traffic demand of the elevator (the car 13), there is no registration of the hall call on each floor, and the state where the car 13 is closed in a non-directional direction for a predetermined time (for example, 1 hour) ) If the above is continued, it is determined that it is in a quiet state (Yes in step S11).

  In a quiet state, the elevator control device 22 includes a power supply for each device 23 such as “door”, “in-car lighting”, “in-car indicator”, “in-car calling device”, “landing indicator”, etc. A standby signal for shutting off the power supply to the drive device 21 is output, and the elevator is switched to the power saving mode (step S12).

  However, it is assumed that the security door 24 is always supplied with power and is operating even in the power saving mode. Further, the answering lamp of the hall call button 16 is in the off state, but only call registration by button operation is possible.

  Here, it is assumed that the user comes to the landing on the first floor during the power saving mode. In the first embodiment, when the lock mechanism of the security door 24 is released, it is determined that the user has come to the landing.

  That is, when the elevator control device 22 inputs a lock mechanism release signal from the security door 24, the elevator control device 22 determines that the user has come to the landing (Yes in step S13). Then, the elevator control device 22 turns on the power to each device 23, further turns on the power of the drive device 21 to cancel the standby state, and returns the elevator from the power saving mode to the normal operation mode (step). S14).

  As described above, according to the first embodiment, in the power saving mode, the power of each device (including the drive device) of the elevator is triggered by the release of the lock mechanism of the security door 24 as a trigger. Before the user actually uses the elevator, that is, before operating the hall call button 16 installed at the hall, each device is brought up to an operable state and smoothly returned to the normal operation mode. be able to.

  In the above-described embodiment, the description has been given on the assumption that the security door 24 is installed at the landing on the first floor, which is the reference floor, but the same security door 24 may be installed at the landing on each floor. According to such a configuration, it is possible to detect a user who uses the elevator (car 13) on each floor and smoothly return from the power saving mode to the normal operation mode.

(Second Embodiment)
Next, a second embodiment will be described.
In the second embodiment, a security camera is used as the user detection means.

  FIG. 3 is a diagram illustrating a configuration of an elevator power saving system according to the second embodiment. In FIG. 3, the same parts as those in FIG. 1 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  A security camera 25 for photographing a user who has come to the landing is installed at the landing on the first floor, which is the reference floor. An image photographed by the security camera 25 is transferred to the elevator control device 22.

  In such a configuration, as described in the flowchart of FIG. 2, when there is no registration of the hall call on each floor, and the state where the car 13 is closed in a non-directional direction continues for a predetermined time (for example, 1 hour) or more. In other words, the device 23 and the drive device 21 are turned off and switched to the power saving mode.

  However, the security camera 25 is operating even in the power saving mode, and constantly monitors the landing state. Further, the answering lamp of the hall call button 16 is in the off state, but only call registration by button operation is possible.

  Here, it is assumed that a user comes to the landing on the first floor during the power saving mode. In the second embodiment, the elevator controller 22 analyzes the captured image of the security camera 25 installed on the first floor and recognizes the presence of the user. It should be noted that a well-known method is used for image analysis processing, and detailed description thereof is omitted here.

  When the elevator control device 22 detects that a user has arrived at the hall based on the image taken by the security camera 25, the elevator control device 22 turns on the power of each device 23 and also turns on the power of the drive device 21 to enter the standby state. Is released. As a result, the power of all elevator devices is turned on and the normal operation mode is restored.

  As described above, according to the second embodiment, in the power saving mode, the power source of each device (including the drive device) of the elevator triggered by the user being photographed by the security camera 25 installed at the hall. As in the first embodiment, each device can be operated before the user actually uses the elevator, that is, before operating the hall call button 16 installed at the hall. It is possible to return to the normal operation mode smoothly by starting up to the state.

  In addition, although the said embodiment demonstrated the structure where the security camera 25 was installed in the hall of the 1st floor which is a reference | standard floor, you may install the same security camera 25 in the hall of each floor. According to such a configuration, it is possible to detect a user who uses the elevator (car 13) on each floor and smoothly return from the power saving mode to the normal operation mode.

(Third embodiment)
Next, a third embodiment will be described.
The third embodiment is characterized in that an interphone is used as the user detection means.

  FIG. 4 is a diagram illustrating a configuration of an elevator power saving system according to the third embodiment. In FIG. 4, the same parts as those in FIG. 1 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  An interphone 27 is installed in each room 26 of the building. The interphone 27 is connected to the elevator control device 22 and can notify the use of the elevator from the room.

  In such a configuration, as described in the flowchart of FIG. 2, when there is no registration of the hall call on each floor, and the state where the car 13 is closed in a non-directional direction continues for a predetermined time (for example, 1 hour) or more. In other words, the device 23 and the drive device 21 are turned off and switched to the power saving mode. The intercom 27 in each room 26 is always in operation regardless of the elevator operation. Further, the answering lamp of the hall call button 16 is in the off state, but only call registration by button operation is possible.

  Here, in the third embodiment, it is assumed that the user notifies the use of the elevator through the interphone 27 installed in any one of the rooms 26 during the power saving mode. When the elevator control device 22 receives the elevator use notification from the interphone 27, it turns on the power of each device 23 and also turns on the power of the drive device 21 to cancel the standby state. As a result, the power of all elevator devices is turned on and the normal operation mode is restored.

  As described above, according to the third embodiment, during the power saving mode, each device (including the drive device) of the elevator is triggered by the fact that the user has notified the use of the elevator through the interphone 27 installed in each room 26. In the same manner as in the first embodiment, each device is turned on before the user actually uses the elevator, that is, before operating the hall call button 16 installed at the hall. It is possible to start up to an operable state and smoothly return to the normal operation mode.

(Fourth embodiment)
Next, a fourth embodiment will be described.
The fourth embodiment is characterized in that an operation panel is used as the user detection means.

  FIG. 5 is a diagram illustrating a configuration of an elevator power saving system according to the fourth embodiment. In FIG. 5, the same parts as those in FIG. 1 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  An operation panel 28 that can be operated by a user is installed at a landing on the first floor, which is a reference floor. The operation panel 28 has operation buttons for the user to give some instructions at the landing. Specifically, the operation buttons include an interphone call button connected to each room, a power button for turning on / off a lighting device at the hall, and the like. This operation panel 28 is connected to the elevator control device 22, and a signal by a button operation is input to the elevator control device 22.

  In such a configuration, as described in the flowchart of FIG. 2, when there is no registration of the hall call on each floor, and the state where the car 13 is closed in a non-directional direction continues for a predetermined time (for example, 1 hour) or more. In other words, the device 23 and the drive device 21 are turned off and switched to the power saving mode.

  However, it is assumed that the operation panel 28 is operating even during the power saving mode. Further, the answering lamp of the hall call button 16 is in the off state, but only call registration by button operation is possible.

  Here, it is assumed that a user comes to the landing on the first floor during the power saving mode. In the fourth embodiment, the elevator control device 22 inputs a signal when the user operates the operation panel 28 installed on the first floor, thereby recognizing the presence of the user.

  When the elevator control device 22 detects that a user has arrived at the landing based on an input signal from the operation panel 28, the elevator control device 22 turns on the power of each device 23, and further turns on the power of the drive device 21. Release the state. As a result, the power of all elevator devices is turned on and the normal operation mode is restored.

  As described above, according to the fourth embodiment, in the power saving mode, the power source of each device (including the drive device) of the elevator is triggered by the user's operation of the operation panel 28 installed at the landing. In the same manner as in the first embodiment, each device can be operated before the user actually uses the elevator, that is, before operating the hall call button 16 installed at the hall. Up to the normal operation mode.

  In the above-described embodiment, the description has been given on the assumption that the operation panel 28 is installed at the landing on the first floor, which is the reference floor. However, the same operation panel 28 may be installed at the landing on each floor. According to such a configuration, it is possible to detect a user who uses the elevator (car 13) on each floor and smoothly return from the power saving mode to the normal operation mode.

  Further, as the operation panel 28 installed at the landing, a landing destination floor registration device 29 as shown in FIG. 6 may be used. The landing destination floor registration device 29 is a device capable of registering a destination floor in advance at the landing before the user gets on the car 13, and an operation unit 30 for registering the destination floor by button operation and registration. And a display unit 31 for displaying a message such as the number assigned to the destination floor.

  In the group management system having a plurality of elevators, the destination floor of the user can be known in advance through the landing destination floor registration device 29. For example, the same car is allocated to the users who go to the same floor. Thus, efficient operation control can be performed.

  Here, if the user powers on each device when the destination floor is registered using the landing destination floor registration device 29 installed at the landing during the power saving mode, the user completes the registration operation. Thus, while waiting in front of the door, each device can be started up to an operable state and can be smoothly returned to the normal operation mode.

(Fifth embodiment)
Next, a fifth embodiment will be described.
The fifth embodiment is characterized in that a radio wave detector is used as the user detection means.

  FIG. 7 is a diagram illustrating a configuration of an elevator power saving system according to the fifth embodiment. In FIG. 7, the same components as those in FIG. 1 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  A radio wave detector 33 for detecting radio waves of the mobile phone device 32 possessed by the user is installed at the landing on the first floor, which is the reference floor. The mobile phone device 32 always transmits radio waves having a specific frequency with a base station (not shown). The radio wave detector 33 detects the radio wave of the mobile phone device 32 within a predetermined range. The radio wave detector 33 is connected to the elevator control device 22, and outputs a detection signal to the elevator control device 22 when the radio wave of the mobile phone device 32 is detected.

  In such a configuration, as described in the flowchart of FIG. 2, when there is no registration of the hall call on each floor, and the state where the car 13 is closed in a non-directional direction continues for a predetermined time (for example, 1 hour) or more. In other words, the device 23 and the drive device 21 are turned off and switched to the power saving mode.

  However, the radio wave detector 33 is assumed to be operating even during the power saving mode. Further, the answering lamp of the hall call button 16 is in the off state, but only call registration by button operation is possible.

  Here, it is assumed that a user comes to the landing on the first floor during the power saving mode. In the fifth embodiment, a user has a mobile phone device 32, and the elevator control device 22 outputs a signal when the radio wave detector 33 installed on the first floor detects the radio wave of the mobile phone device 32. Recognize the presence of the user by inputting.

  When the elevator control device 22 detects that a user has arrived at the landing based on the radio wave detection signal from the radio wave detector 33, the elevator control device 22 turns on the power of each device 23 and further turns on the power of the drive device 21. Release the standby state. As a result, the power of all elevator devices is turned on and the normal operation mode is restored.

  As described above, according to the fifth embodiment, during the power saving mode, each radio device 33 (elevator) installed in the hall senses the radio wave of the user's mobile phone device 32 as a trigger. Even when the power of the drive device (including the drive device) is turned on, as in the first embodiment, before the user actually uses the elevator, that is, before operating the hall call button 16 installed at the hall. Each device can be started up to an operable state and smoothly returned to the normal operation mode.

  In the above embodiment, the description has been given on the assumption that the radio wave detector 33 is installed at the landing on the first floor, which is the reference floor, but the same radio wave detector 33 may be installed at the hall on each floor. good. According to such a configuration, it is possible to detect a user who uses the elevator (car 13) on each floor and smoothly return from the power saving mode to the normal operation mode.

(Sixth embodiment)
Next, a sixth embodiment will be described.
In the said 1st-5th embodiment, when the user was detected, it returned to the normal operation mode by turning on the power supply of each apparatus of an elevator simultaneously. However, if the power of each device is turned on at the same time, there is a problem that the power consumption at that moment becomes very high. Therefore, the sixth embodiment is characterized in that the order in which the devices are returned is changed according to the situation when the user is detected.

  FIG. 8 is a diagram for explaining the relationship between the car position and the return priority of each device in the sixth embodiment. FIG. 8A shows the case where the car position is the same as the call position, and FIG. The order of return priority when the car position and the calling position are different is shown.

  There are “door”, “in-car lighting”, “in-car indicator”, “in-car calling device”, and “travel-related equipment” as return target devices. As described above, “inside-car lighting” is lighting equipment installed on the ceiling or the like in the car 13. The “in-car display” is a display device for displaying the current car position and driving direction in the car 13. The “car calling device” includes a destination floor registration button 15 in the car 13 and its response lamp. The “landing display” is a display device for displaying the current car position, driving direction, and the like at the landing.

  Further, the “travel related device” is the drive device 21 including an inverter, a converter, and the like.

  Here, when the car position (the current position of the car 13) and the calling position (the floor where the hall call was made) are the same, as shown in FIG. Specifically, devices that are easily noticeable by the user, such as “doors”, “in-car lighting”, and “in-car display”, are restored preferentially.

  On the other hand, when the car position and the calling position are different, as shown in FIG. 8B, the “travel-related equipment” is preferentially returned, and the “door”, “car Devices such as “inside lighting” and “inside-car display” will be postponed.

  Further, when the “landing indicator” is returned, only the “landing indicator” on each floor or the “landing indicator” on the floor where the hall call is made is returned according to the time zone at that time.

This will be described in detail below.
FIG. 9 is a flowchart showing the processing operation during the return operation by the elevator control device 22 of the present system.

  Now, it is assumed that the user is detected by any one of the methods of the first to fifth embodiments, and the power of each device is turned on to return from the power saving mode to the normal operation mode.

  First, the elevator control device 22 determines whether or not the time when the user is detected is included in a preset quiet time zone (step S21).

  The “quiet time zone” mentioned here is a time zone in which the elevator is least used, such as a night time period to an early morning time period (for example, 0:00 to 5:00).

  However, since the quiet time zone varies depending on the traffic situation of the building, it is assumed that the quiet time zone is set in advance in a memory (not shown) in the elevator control device 22 for each building (property).

  If it is a quiet time zone (Yes in step S21), the elevator control device 22 turns on the power of the “depot indicator” installed on the floor where the user registers the call (step S21). S22). At that time, the response lamp of the hall call button 16 on the floor is also turned on.

  On the other hand, if it is outside the quiet time zone (No in step S21), the elevator control device 22 supplies power to the “depot indicator” installed on all floors including the floor where the user registered the call. To return (step S22). At that time, only the response lamp of the hall call button 16 on the floor is turned on.

  In this way, when a user comes to the landing and registers a landing call during a quiet time, power consumption can be suppressed as much as possible by returning only the “landing indicator” installed on that floor. , It does not give anxiety to users.

  On the other hand, since it is highly likely that users will occur on each floor except during off-peak hours, users can be relocated to other floors by returning the “landing indicators” installed on all floors. If you come, you can deal with it.

At this point, devices other than the “landing indicator” are in a standby state and are not yet ready for driving service. Therefore, the time required to complete the restoration of all the devices may be displayed on the “Place Display” on the floor where the hall call is registered to reassure the user (Step S24).
Next, the elevator control device 22 determines whether or not the car position (current position of the car 13) is the same as the call position (floor on which the hall call was made) (step S25). The car position is detected using a pulse signal output from a pulse encoder (not shown) attached to the rotary shaft of the hoisting machine 11 during the elevator operation.

  If the car position and the call position are the same, that is, if there is a hall call on the floor where the car 13 is stopped by the power saving mode (Yes in step S25), the description will be made with reference to FIG. As described above, the elevator control device 22 turns on power to devices that are easily noticed by the user, such as “door”, “in-car lighting”, and “in-car display”, and restores them preferentially ( Step S26). After that, the elevator control device 22 turns on the power to the “travel-related equipment”, that is, the drive device 21 including an inverter, a converter, and the like (step S27).

  On the other hand, if the car position is different from the call position, that is, if there is a hall call on a floor different from the floor where the car 13 is stopped due to the power saving mode (No in step S25), FIG. As described in b), the elevator control device 22 turns on the power to the “travel-related equipment” and restores it preferentially (step S28). At that time, the “door”, “ The “in-car lighting” and “in-car indicator” are later restored (step S29).

  Thus, in a situation where the car position and the calling position are the same, and the user can get on the car 13 immediately, the user can easily get on the car 13 by preferentially returning the device that is easily noticeable to the user. The return operation can be performed without giving a feeling. In particular, when the car 13 is close to the user, such as a prospective elevator, when the state of the car is clearly seen, it is misunderstood that the user has failed by returning the priority of the equipment in the car. Can be avoided. In addition, since there is some time until the user gets into the car 13 and registers the destination floor, the “travel-related equipment” may be returned using that time.

  On the other hand, if the car position is different from the call position and the user is not ready to get on the car 13 immediately, the “travel-related equipment” is returned first, and the car 13 is moved as soon as possible to call the hall. If the “door”, “in-car light”, and “in-car indicator” are returned during the movement, the return operation can be performed efficiently. In this case, when the car 13 arrives, the return of all the devices is almost completed, so that the user can get on without any particular attention.

  As described above, according to the sixth embodiment, by changing the order in which the devices are restored in accordance with the situation when the user is detected, it is possible to perform efficient restoration operation while suppressing wasteful power. It is possible to smoothly return to the normal operation mode while avoiding anxiety of the person.

  As described above, according to these embodiments, it is possible to provide an elevator power saving system that can smoothly return to a normal operation mode when the power of each device is shut down for power saving. it can.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
