Description

Elevator device and control method thereof
Technical Field
The present invention relates to an elevator apparatus and a control method thereof, and is suitably used in, for example, an ultra-high-speed elevator apparatus.
Background
In recent years, with the increase in the number of stories in buildings, the speed of elevator apparatuses has been increasingly increased. In such a high-speed elevator apparatus (hereinafter referred to as an ultra-high-speed elevator apparatus), the air pressure change per unit time and the total air pressure change amount are large, and passengers often feel a sense of ear congestion due to the large air pressure change.
Therefore, in order to reduce such an ear blockage feeling, it has been conventionally proposed to mount an air pressure control device for controlling the internal air pressure of the car in accordance with the external air pressure of the car in the ultra-high speed elevator apparatus. Here, in order to maintain the internal air pressure of the car in an optimum state, it is necessary to improve the airtightness of the car.
However, if the airtightness of the car is improved, ventilation in the car is no longer possible in an emergency such as a power failure, and there is a possibility that the passengers in the car will lack oxygen. Therefore, conventionally, in an ultra-high-speed elevator apparatus, a ventilation window that is closed in a normal state but automatically opened in an emergency is provided.
Patent document 1 discloses a structure for automatically opening and closing a ventilation window opening/closing member at the time of power failure and at the time of power restoration (at the time of normal power supply) in association with a relevant ventilation window. Patent document 2 discloses: when the ventilation window device is not opened even if a preset ventilation window fault check period is exceeded, an opening command is given to the ventilation window device, and the fault or normality of the ventilation window device is detected according to whether the ventilation window device is opened by the opening command.

Detailed Description
One embodiment of the present invention is described below in detail with reference to the accompanying drawings.
(1) Structure of elevator device of the present embodiment
In fig. 1, 1 denotes an elevator apparatus of the present embodiment as a whole. The elevator apparatus 1 is a super high-speed elevator apparatus installed in a high-rise building, and includes a car 2, a control panel 3, and a control device 4.
The car 2 has a box-like shape including a side panel 10A, a ceiling panel 10B, and a floor panel 10C, each forming 4-directional side surfaces, and engages with a hoist, not shown, provided on the uppermost portion of the hoistway via a main rope, and the main rope is wound up or down by the hoist to be lifted and lowered in the hoistway.
A door 11 disposed so as to be openable and closable in the arrow γ 1 direction is attached to the side panel 10A on the front side of the car 2. Further, by disposing a seal for closing the gap between the door 11 and the side panel 10A on the front side of the car 2, the airtightness inside the car 2 can be maintained in the state where the door 11 is closed. Therefore, the blower 12 is provided above the car 2, and the air pressure inside the car 2 can be controlled by sending the air outside the car 2 to the inside of the car 2 by the blower 12.
Further, a ventilation window device 13 for ventilating the inside of the car 2 in an emergency in which power supply is cut off is provided on the side surface side of the car 2. The outside of the ventilation window device 13 is covered with an outer case 14 having high airtightness, and is provided with a ventilation window opening/closing door 15 that opens or closes a ventilation opening k (fig. 3) described later provided as a ventilation opening in the side panel 10A on the side surface side of the car 2. Therefore, even when the power supply to the blower 12 is cut off in an emergency, the ventilation window opening/closing door 15 is opened to take the outside air into the car 2, and thus it is possible to prevent the passengers in the car 2 from becoming short of oxygen.
The control panel 3 is a control device that controls the operation of the elevator apparatus 1, and is installed in, for example, a machine room provided above the hoistway. The control panel 3 always recognizes the position of the car 2 by a sensor provided in the car 2 or the hoistway, and controls the hoisting machine so that the car 2 stops at a required floor in accordance with an operation of a passenger on an operation panel provided in an elevator hall of each floor or an operation panel provided in the car 2.
The control device 4 is a control device that controls opening and closing of the ventilation window opening/closing door 15 of the ventilation window device 13 provided in the car 2, and has a computer structure including the CPU20, the memory 21, and the 1 st and 2 nd timers 22 and 23. The memory 21 stores a ventilation window device control program 24, and the CPU20 controls the ventilation window device 13 to open and close the ventilation window opening/closing door 15 as necessary by executing the ventilation window device control program 24.
Fig. 2 shows a logical configuration of the control device 4. As shown in fig. 2, the control device 4 includes a control unit 30, a normal configuration unit 31, and a perfection confirming unit 32. All of the control unit 30, the normal configuration unit 31, and the integrity check unit 32 are functional units embodied by the CPU20 (fig. 1) executing the ventilation window device control program 24 (fig. 1).
The control unit 30 is a functional unit as follows: information such as the current position of the car 2 (fig. 1), the open/close state of the doors 11 of the car 2, and the presence or absence of an emergency situation is appropriately acquired from the control panel 3, and the normal configuration unit 31 and the integrity confirmation unit 32 are controlled based on the acquired information. For example, when information to this effect is given from the control panel 3 in an emergency, the control unit 30 gives an instruction to the normal configuration unit 31 to open the ventilation window opening/closing door 15 (fig. 1) of the ventilation window device 13.
The normal configuration unit 31 is a functional unit that controls the operation of the ventilation window device 13 in a normal state or an emergency state. The normal configuration unit 31 controls the ventilation window device 13 so that the ventilation window opening/closing door 15 is maintained in the door closed state during normal operation, and on the other hand, operates the ventilation window device 13 so that the ventilation window opening/closing door 15 is opened in an emergency according to an instruction given from the control unit 30 as described above.
The integrity confirming unit 32 is a functional unit having a function of appropriately confirming the integrity of the louver device 13 (hereinafter, this is referred to as a louver device integrity confirming function). Actually, the integrity confirmation unit 32 confirms the integrity of the louver device 13 by operating the louver device 13 to open and close the louver opening and closing door 15, for example, at the following timings: the car 2 keeps the door 11 closed and keeps the standby state for a long time stopping at any floor for more than the given 1 st time; when a given 2 nd time sufficiently longer than the 1 st time elapses since the completion of the louver device 13 is finally confirmed, the timing at which the car 2 is about to stop at any floor is reached.
As means for realizing such a ventilation window device integrity checking function, the integrity checking unit 32 is provided with an integrity checking timing generation unit 33, an elevator state detection unit 34, a ventilation window opening/closing operation unit 35, an operation checking unit 36, and an abnormality monitoring unit 37.
The integrity check timing generation unit 33 has a function of generating a timing at which the integrity of the ventilation window device 13 is checked. Specifically, the integrity check timing generation unit 33 measures the elapsed time since the car 2 stopped at any floor using the 1 st timer 22 (fig. 1), and notifies the louver opening/closing operation unit 35 of the fact that the car 2 stopped at any floor in a standby state with the doors 11 kept closed for a predetermined 1 st time T1 (for example, 10 minutes). The integrity check timing generation unit 33 measures an elapsed time from the last check of the integrity of the louver device 13 by using the 2 nd timer 23 (fig. 1), and notifies the elevator state detection unit 34 of the fact when the elapsed time is equal to or longer than a predetermined 2 nd time T2 (for example, 1 hour) sufficiently longer than the 1 st time T1.
When the 2 nd time T2 has elapsed since the integrity check timing generation unit 33 was notified of the last confirmation of the integrity of the louver device 13, the elevator state detection unit 34 acquires the current state of the elevator device 1 from the control panel 3 via the control unit 30. Then, the elevator state detection unit 34 obtains the timing at which the car 2 is to be stopped at any floor next based on the obtained current state of the elevator apparatus 1, and gives an instruction to the louver opening/closing operation unit 35 at the timing to open and close the louver opening/closing door 15 of the louver device 13.
When the integrity check timing generation unit 33 notifies that the standby time of the car 2 has continued for the 1 st time T1 or when the elevator state detection unit 34 instructs the louver opening/closing door 15 of the louver device 13 to open/close at a predetermined timing, the louver device 35 controls the louver device 13 to open/close the louver opening/closing door 15 at the instructed timing.
The operation checking unit 36 monitors the opening and closing operation of the louver opening and closing door 15 of the louver device 13 under the control of the louver opening and closing operation unit 35, and determines whether or not the opening and closing operation is normally performed. When an abnormality in the opening/closing operation of the ventilation window opening/closing door 15 is detected, the operation confirmation unit 36 outputs an abnormality detection notification to that effect to the abnormality monitoring unit 37.
When the operation confirmation unit 36 receives the abnormality detection notification, the abnormality monitoring unit 37 transmits the abnormality detection notification indicating that an abnormality has occurred in the opening/closing operation of the ventilation window opening/closing door 15 to the control panel 3 via the control unit 30, for example. As a result, the control panel 3 executes control processing for performing predetermined abnormality detection such as emergency stop of the car 2 at the nearest floor based on the abnormality detection notification.
(2) Concrete structure example of ventilation window device
Fig. 3 is a sectional view showing a specific configuration example of the ventilation window device 13 as viewed from the direction of arrow a in fig. 1. As a structure for opening or closing the ventilation opening k in an emergency in which the power supply is cut off, the ventilation window device 13 includes: a ventilation window opening/closing door 15 rotatably disposed about a shaft 40; a closing solenoid 41 for closing the ventilation window opening/closing door 15; a housing 42 for fixing the closing solenoid 41 to the side panel 10A of the car 2; a link mechanism 44 for connecting one end of the opening/closing shaft 43 of the closing solenoid 41 to the ventilation window opening/closing door 15; and a compression spring 45 provided between the housing 42 and the opening/closing shaft 43 and biasing an engagement portion 43A provided at the other end of the opening/closing shaft 43 in a direction away from the housing 42 as indicated by an arrow α 2.
The link mechanism 44 converts the linear motion of the opening/closing shaft 43 of the closing solenoid 41 into the rotational motion of the ventilation window opening/closing door 15 using a long hole or the like. As shown by the solid line in fig. 3, the opening/closing shaft 43 of the closing solenoid 41 moves in the arrow α 3 direction by the magnetic force of electromagnetic induction when the closing solenoid 41 is energized, thereby rotating the louver opening/closing door 15 in the closing direction indicated by the arrow β 2, while, when the closing solenoid 41 is de-energized, moves in the arrow α 2 direction by the elastic force of the compression spring 45, thereby rotating the louver opening/closing door 15 in the opening direction indicated by the arrow β 1, as shown by the two-dot chain line in fig. 3.
The ventilation window device 13 includes, as a mechanism for locking the door open state of the ventilation opening k of the ventilation window opening/closing door 15: a locking solenoid 47 that engages one end of the locking shaft 46 with the ventilation window opening/closing door 15 to lock the ventilation window opening/closing door 15 in a door-closed state; a housing 48 for fixing the locking solenoid 47 to the side panel 10A; and a compression spring 49 provided between the lock shaft 46 of the lock solenoid 47 and the housing 48, and biasing an engagement portion 46A provided on the other end side of the lock shaft 46 in a direction away from the housing 48 as indicated by an arrow α 1.
As shown by the solid line in fig. 3, the lock shaft 46 of the lock solenoid 47 moves in the arrow α 4 direction by the magnetic force of electromagnetic induction when the lock solenoid 47 is energized, thereby locking the ventilation window opening/closing door 15 in the door closed state, and on the other hand, moves in the arrow α 1 direction by the elastic force of the compression spring 49 when the lock solenoid 47 is de-energized, thereby returning to the unlocked position in which the ventilation window opening/closing door 15 is unlocked, as shown by the two-dot chain line in fig. 3.
The ventilation window device 13 is provided with an operation switch 50 for energizing/deenergizing the power supply to the lock solenoid 47 and the close solenoid 41 in accordance with the open/close state of the ventilation window opening/closing door 15. Actually, the operation switch 50 is composed of the following elements: a movable terminal 50A provided to be movable in the direction of an arrow ω 1 and the direction of an arrow ω 2 and biased in the direction of the arrow ω 1; a 1 st terminal 50B which is pressed by the louver opening/closing door 15 and is arranged to be in contact with the movable terminal 50A moving in the direction of the arrow ω 1 when the louver opening/closing door 15 is in the door-closed state; and a 2 nd terminal 50C disposed so as to be in contact with the movable terminal 50A moving in the direction of the arrow ω 1 by an urging force when the ventilation window opening/closing door 15 is in the door-open state.
In a normal state where the closing solenoid 41 is energized to close the ventilation window opening/closing door 15, the movable terminal 50A of the operation switch 50 is brought into contact with the 1 st terminal 50B to supply the driving current I to the locking solenoid 47 via the movable terminal 50A and the 1 st terminal 50B1. As a result, the lock solenoid 47 is energized to move the lock shaft 46 in the arrow α 4 direction, and thus the ventilation opening/closing door 15 is locked to the doorAn off state.
In addition, since the movable terminal 50A is separated from the 2 nd terminal 50C at this time, power is not supplied to the closing solenoid 41, and the closing solenoid 41 is turned off, thereby saving power. Even when the closing solenoid 41 is deenergized in this manner, the ventilation window opening/closing door 15 is locked in the door closed state by the lock shaft 46 of the lock solenoid 47, and therefore the ventilation window opening/closing door 15 is not opened.
On the other hand, in an emergency (power-off state), since the power supply to the locking solenoid 47 is cut off, the locking shaft 46 of the locking solenoid 47 is retracted to the position indicated by the two-dot chain line in fig. 3 by the biasing force of the compression spring 49, and the ventilation opening/closing door 15 locked in the door closed state by the locking solenoid 47 is in the unlocked state. As a result, the opening/closing shaft 43 of the closing solenoid 41 in the deenergized state is retracted to the position indicated by the two-dot chain line by the elastic force of the compression spring 45, and the ventilation window opening/closing door 15 is rotated in the rotational direction indicated by the arrow β 1 by the action of the link mechanism 44 accompanying this, whereby the door is opened to the position indicated by the two-dot chain line. The ventilation opening k of the car 2 is thereby opened, and ventilation of the interior of the car 2 is performed.
In the present embodiment, in the ventilation window device 13, when the door of the ventilation window opening/closing door 15 is closed, the gasket 51 is provided between the ventilation window opening/closing door 15 and the side panel 10A. The gasket 51 is provided around the ventilation opening k of the side panel 10A to close the gap between the ventilation window opening/closing door 15 and the side panel 10A. Thus, when the door of the ventilation window opening/closing door 15 is closed, the gasket 51 is in contact with the peripheral edge of the ventilation window opening/closing door 15, and the airtight state of the car 2 can be maintained between the ventilation window opening/closing door 15 and the side panel 10A around the ventilation opening k.
(3) Specific processing contents of the integrity confirmation unit
Next, the flow of a series of processes (hereinafter, referred to as a louver device integrity confirmation process) executed by the integrity confirmation unit 32 (fig. 2) of the control device 4 will be described with respect to the confirmation of the integrity of the louver device 13.
Fig. 4 shows a specific flow of the ventilation window device integrity check process. When the operation of the elevator apparatus 1 is started, the ventilation window apparatus integrity check process is started, and first, the integrity check timing generation unit 33 determines whether or not the elapsed time since the car 2 stopped at any floor exceeds the 1 st time T1 based on the count value of the 1 st timer 22 (fig. 1) (S1).
When a negative result is obtained in this determination, the integrity check timing generation unit 33 determines whether or not the elapsed time since the integrity of the ventilation window device 13 was last checked exceeds the 2 nd time T2 based on the count value of the 2 nd timer 23 (fig. 1) (S2).
Then, if a negative result is obtained in this determination, the integrity check timing generation unit 33 returns to step S1, and thereafter repeats the loop of step S1-step S2-step S1 until an affirmative result is obtained in step S1 or step S2.
Then, the integrity check timing generation unit 33 finally notifies the elevator state detection unit 34 of the fact when an affirmative result is obtained in step S2, and notifies the ventilation window opening/closing operation unit 35 of the fact when an affirmative result is obtained in step S1.
When the integrity check timing generation unit 33 is notified, the elevator state detection unit 34 acquires the current state of the elevator apparatus 1 from the control panel 3 (fig. 2) via the control unit 30 (fig. 2), and calculates the timing at which the louver opening/closing door 15 should be opened and closed to check the integrity of the louver device 13 based on the acquired current state of the elevator apparatus 1 (S3).
Specifically, the elevator state detection unit 34 acquires information such as the time until the car 2 stops at any floor next from the control panel 3 via the control unit 30, and calculates the latest time (hereinafter referred to as final timing time) from the current time point at which the opening and closing operation of the louver opening and closing door leaf 15 for confirming the integrity of the louver device 13 should be started in order to complete the opening and closing operation until the car 2 stops at the floor based on the acquired information.
When it is determined that the opening and closing operation of the louver opening and closing door 15 cannot be completed until the car 2 stops at any one of the following floors, the elevator state detecting unit 34 calculates a final timing from the current time to start the opening and closing operation in order to complete the opening and closing operation of the louver opening and closing door 15 for confirming the integrity of the louver device 13 until the car stops at the following floor.
Then, the elevator state detection unit 34 notifies the ventilation window opening/closing operation unit 35 of the final timing time calculated in this manner.
When the elapsed time from when the integrity check timing generation unit 33 was notified that the car 2 stopped at any floor exceeds the 1 st time T1 or the final timing time was notified from the elevator state detection unit 34, the louver opening/closing operation unit 35 causes the louver opening/closing door 15 of the louver device 13 to open and close at a timing immediately before the car 2 stopped at any floor (S4).
Specifically, for example, when the elapsed time from when the integrity check timing generation unit 33 is notified that the car 2 stops at any floor exceeds the 1 st time T1, the louver opening/closing operation unit 35 immediately stops the supply of the drive current to the locking solenoid 47 described above with reference to fig. 3 to unlock the louver opening/closing door 15 of the locking solenoid 47, thereby opening the louver opening/closing door 15, and then supplies the drive current to the closing solenoid 41 to close the louver opening/closing door 15.
When the final timing time is notified from the elevator state detecting unit 34, the ventilation window opening/closing operation unit 35 stops the supply of the drive current to the locking solenoid 47 at the timing when the final timing time has elapsed, thereby unlocking the ventilation window opening/closing door 15 by the locking solenoid 47, so as to open the ventilation window opening/closing door 15, and thereafter supplies the drive current to the closing solenoid 41, thereby closing the ventilation window opening/closing door 15.
At this time, the ventilation window opening/closing operation unit 35 monitors the contact of the movable terminal 50A with the 1 st terminal 50B and the 2 nd terminal 50C in the operation switch 50 described above with respect to fig. 3, and thereafter determines whether or not the ventilation window opening/closing door 15 is normally opened or closed (S5).
Then, if a positive result is obtained in this determination, the ventilation window opening/closing operation unit 35 notifies the integrity check timing generation unit 33 of this fact. In this way, at this time, the integrity check timing generation unit 33 executes the processing of step S1 and thereafter. Thus, the processing of step S1 to step S5 is repeated thereafter.
On the other hand, if a negative result is obtained in the determination in step S, the ventilation window opening/closing operation unit 35 notifies the abnormality monitoring unit 37 that an abnormality has occurred in the opening/closing of the ventilation window opening/closing door 15. When the abnormality monitoring unit 37 is notified of the abnormality, a predetermined abnormality detection process is executed. Specifically, when the operation confirmation unit 36 notifies that an abnormality occurs in opening and closing the ventilation window opening/closing door 15, the abnormality monitoring unit 37 transmits an abnormality detection notification to that effect to the control panel 3 via the control unit 30. As a result, the control panel 3 executes the control processing at the time of the predetermined abnormality detection such as stopping the car 2 at the nearest floor as described above.
In this case, the integrity check unit 32 ends the ventilation window device integrity check process after that. Consequently, the integrity of the louver device 13 is not checked until the maintenance of the louver device 13 is performed, and the elevator apparatus 1 itself stops operating.
(4) Effects of the present embodiment
As described above, in the elevator apparatus 1 of the present embodiment, when the standby state in which any one floor is kept stopped for a long time in a state in which the car 2 closes the door 11 exceeds the 1 st time T1 or when such a long-time standby state exceeds the 2 nd time T2 sufficiently longer than the 1 st time T1, the louver device 13 is operated at a timing just before the car 2 stops at any one floor to open and close the louver opening/closing door 15, thereby confirming the integrity of the louver device 13.
In this case, in the ultra-high-speed elevator apparatus, if the integrity of the louver device 13 is checked at an arbitrary timing, the louver opening/closing door is difficult to open and close due to the influence of the rising current phenomenon, and it may be difficult to accurately check the integrity of the louver device 13. In particular, when the ventilation window opening/closing door 15 of the ventilation window device 13 is opened when the door 11 (fig. 1) of the car 2 is opened, the ventilation window opening/closing door 15 may not be closed because air flows through a path such as the elevator hall, the doorway of the car 2, the inside of the car 2, the ventilation opening k, and the hoistway.
In this regard, in the elevator apparatus 1 of the present embodiment, since the integrity of the louver device 13 is checked at the timing when the door 11 of the car 2 is closed as described above, the integrity of the louver device 13 can be accurately checked without being affected by the rising current phenomenon. In the elevator apparatus 1, since the louver opening/closing door 15 is opened and closed during the stop of the car 2 or during the low-speed travel before the stop, the integrity of the louver device 13 can be checked while the influence of the rising flow is significantly reduced as compared with when the car 2 is ascending and descending at a high speed.
In the elevator apparatus 1, in order to confirm the integrity of the louver device 13 at the relevant timing, the integrity of the louver device 13 can be confirmed periodically or in a planned manner by confirming the integrity immediately before the stop of the car 2 during the raising and lowering of the car even in the daytime with a high operation frequency without a long standby.
Further, for example, in the case where the integrity of the ventilation window device 13 is checked immediately before the departure of the car 2, there is a possibility that the departure of the car 2 is stopped due to a slight imperfection, but if the timing is immediately before the stop while the car 2 is standing by for a long time or traveling as in the present embodiment, the abnormality check of the ventilation window device 13 can be performed without lowering the operation efficiency of the elevator device 1.
