Description

The present invention relates to a car control device in an elevator in which a plurality of cars are installed, and a control device for the elevator.

Conventionally, an elevator operating device in which a plurality of baskets are installed has been known (see Patent Document 1). This driving device performs so-called group management by allocating (dispatching) the optimum basket (unit) from a plurality of baskets so that the transportation efficiency of users and the like is high in response to a call for a landing on a predetermined floor. ing.

In addition, in this group management, when the door opening time extension button provided separately from the normal door opening button is pressed in the basket, the basket is stopped for a long time on a predetermined floor for loading and unloading of luggage, and other Since it is expected that the passenger will not be able to respond to the landing call on the floor for a long time, the basket is temporarily excluded from the group management allocation target, and another basket is assigned (distributed) to the landing call. This is intended to improve the transportation efficiency of users and the like.

JP-A-64-43486

In the above elevator, the driving direction (up or down) when the car with the door open time extension button pressed is retained if there is a destination floor call (pressing the destination button in the car), but the destination If there is no floor call, it will not be retained.

Therefore, for example, even when the user uses the door open time extension button instead of the door open button, the driving direction may change if there is no destination floor call. At this time, there has been a problem that the waiting time of the user waiting at the platform on another floor is extended (that is, the transportation efficiency is lowered).

Therefore, the present invention provides a basket control device and an elevator control device that can prevent a decrease in transportation efficiency when a button for extending the door opening time of a basket is pressed in an elevator having a plurality of baskets. Is the subject.

FIG. 1 is a schematic view showing the configuration of an elevator according to the present embodiment. FIG. 2 is a schematic view showing the configuration of the elevator landing and its surroundings. FIG. 3 is a diagram showing the vicinity of the entrance / exit inside the basket. FIG. 4 is a diagram showing a flow when the car of the elevator arrives at the stop floor platform and the extension button is pressed. FIG. 5 is a diagram showing a flow when an elevator car according to another embodiment arrives at the stop floor platform and the extension button is pressed.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIGS. 1 and 2, the elevator according to the present embodiment has a plurality of hoistways 2 extending in the vertical direction across a plurality of floors in the building, and the number of these plurality of hoistways 2. It includes a corresponding number (s) of baskets 3 and an elevator control device 4 that controls the elevator 1.

Further, the elevator 1 has landings 5 corresponding to each hoistway 2 on a plurality of floors, and each landing 5 has a landing door 51 that opens and closes in conjunction with the car door 32, a call button 52 for the car 3, and so on. It has an indicator 53 that displays the position and movement (driving direction, etc.) of each basket 3.

In this elevator 1, the user presses the call button 52 (the landing call is entered) at the landing 5 (predetermined floor) on any floor of the building, so that the car 3 of the plurality of baskets 3 is entered. Arrives (stops) at the landing 5, and the basket door 32 and the landing door 51 open, whereby users and the like can get on and off the basket 3. At this time, the user waiting for the arrival of the basket 3 at the landing 5 can grasp the position and movement (driving direction, etc.) of each basket 3 by looking at the indicator 53.

Each of the plurality of baskets 3 is arranged in each hoistway 2 and moves up and down in the hoistway 2. Specifically, as shown in FIG. 3, each basket 3 has a doorway 311 and a basket body 31 on which a user gets on and off from the doorway 311 and a basket door 32 that opens and closes the doorway 311 of the basket body 31. It has an operation panel 33 that can be operated by the user in the basket main body 31, and a basket control device (basket control device) 34 that controls the basket 3.

The operation panel 33 includes a plurality of destination buttons 331, a plurality of types of door opening buttons 332 and 333 for opening the cage door 32 (two types in the example of the present embodiment), and a closing button (door closing) for closing the cage door 32. Button) 334 and. The operation panel 33 of the present embodiment has an open button (normal door open button) 332 for opening the cage door 32 and a door open state (fully open state) longer than the open button 332, that is, a door open time. It has an extension button 333, which is an extension door opening button, and an extension button 333.

In the basket 3 of the present embodiment, when the open button 332 is pressed, the door open state continues for 5 to 10 seconds (5 seconds in the example of the present embodiment). That is, when the open button 332 is pressed, the cage door 32 opens to the fully open position, and starts closing 5 seconds after the fully open position. On the other hand, when the extension button 333 is pressed, for example, the door open state continues for 2 minutes. That is, when the extension button 333 is pressed, the cage door 32 opens to the fully open position, and starts closing when 2 minutes have passed from the fully opened position. Regardless of which door open button (open button 332, extension button 333) is pressed, if the close button 334 is pressed in the open state, the cage door 32 starts to close at that point. Further, while the open button 332 and the extension button 333 are continuously pressed, the open state is maintained even after the set time (in the example of the present embodiment, the open button 332 is 5 seconds and the extension button is 2 minutes) elapses. Be maintained.

The elevator control device 4 functionally has a group management control unit 41 that performs group management control such as allocation of landing calls to a plurality of baskets 3 (see FIG. 1). In the group management by the group management control unit 41, when a landing call is made at the landing 5 on a predetermined floor (when the call button 52 is pressed at the landing 5), the transportation efficiency of the user or the like is increased. A basket 3 corresponding to the landing call is selected from a plurality of baskets 3, and the selected basket 3 heads for the landing 5 containing the landing call.

The elevator control device 4 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) or an EEPROM (Electrically Erasable Program Read) that stores various programs executed by the CPU and data necessary for the execution in advance. It is composed of a board or a microcomputer provided with a non-volatile memory element such as Only Memory), a volatile storage element such as RAM (Random Access Memory) which is a so-called working memory of the CPU, and peripheral circuits thereof.

The basket control device 34 provided in each basket 3 has an extension button of the basket 3 (among a plurality of types of door open buttons having different open times of the basket door 32) when the car is stopped at the landing 5 on a predetermined floor. The detection unit 341 that can detect that the extension button 333 has been pressed, and the detection unit 341 that can detect that the extension button 333 has been pressed, immediately before the extension button 333 is pressed. It functionally has a basket operation control unit (operation control unit) 342 that keeps holding the operation direction information that has been retained. Here, the "driving direction information" is information about the driving direction (moving direction) in which the basket 3 stopped at the landing 5 on the target floor is scheduled to start moving next. For example, the "driving direction information" when the basket 3 stopped at the platform (target floor) 5 on the target floor is scheduled to rise after the cage door 32 is opened and closed (after the user gets on and off) is The "driving direction information" when the car 3 stopped at the landing 5 on the target floor is scheduled to descend after opening and closing the car door 32 is "downward".

The basket control device 34 also includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) or an EEPROM (Electrically Erasable Program Read) that stores various programs executed by the CPU and data necessary for the execution in advance. It is composed of a board or a microcomputer provided with a non-volatile memory element such as Only Memory), a volatile storage element such as RAM (Random Access Memory) which is a so-called working memory of the CPU, and peripheral circuits thereof.

The control of the basket 3 by the basket control device 34 described above will be specifically described below with reference to FIG.

When the basket 3 arrives at the platform 5 on the target floor (hereinafter, also referred to as "stop floor platform 5A"), the door opens (step S1). At this time, in the basket 3 stopped at the stop floor platform 5A, the destination button 331 of the floor other than the floor on which the platform 5A is located is not pressed. That is, the basket 3 is in a state of being stopped at the stop floor platform 5A by the destination floor call in the final basket 3. When the user in the basket 3 presses the extension button 333, the detection unit 341 detects the pressing of the extension button 333 (step S2: Yes) and outputs a detection signal to the basket operation control unit 342 (basket control device 34). do. Then, when the detection signal is input to the car operation control unit 342, the car operation control unit 342 continues to hold (store) the operation direction information held immediately before the extension button 333 is pressed (step S3). That is, when the car 3 arrives at the stop floor platform 5A, when the extension button 333 is pressed by the user in the car 3 while the car operation control unit 342 holds the driving direction information, the car operation is performed. The control unit 342 continues to hold the driving direction information from the input of the detection signal (that is, from the detection of the press of the extension button 333 by the detection unit 341). For example, when the car 3 rises from the landing 5 on the lower floor and stops (arrives) at the landing 5A on the stop floor, the car operation control unit 342 holds the "upward" driving direction information. The basket operation control unit 342 further keeps the "upward" operation direction information from the input of the detection signal.

Further, when the detection signal is input, the car operation control unit 342 outputs a request signal to the group management control unit 41 requesting that the basket 3 be excluded from the group management control allocation target, and this request signal. The group management control unit 41 that has received the above removes the basket 3 (the basket 3 having the basket operation control unit 342 that outputs the request signal) from the allocation target of the group management control (step S4). The order of steps S3 and S4 is not limited. That is, step S3 and step S4 may be performed at the same time, or may be performed in the reverse order.

When the door closing is started in the basket 3 that is out of the allocation target of the group management control (step S5), the basket operation control unit 342 of the basket 3 directs the basket 3 to the group management control unit 41 and manages the basket 3 as a group. A request signal requesting the return to the control allocation target is output, and the group management control unit 41 that has received the request signal returns the basket 3 to the group management control allocation target (step S6). If the close button 334 is not pressed, the door closing start timing is the time for extending the door opening after the cage door 32 is fully opened (the time when the door opening state is scheduled when the extension button 333 is pressed: this time. In the example of the embodiment, if 2 minutes) has elapsed and the close button 334 is pressed 2 minutes before the cage door 32 is fully opened (door opening extension time), the close button 334 is pressed. It was when it was done.

When the basket 3 returned to the allocation target of the group management control by the start of closing the door of the basket 3 stopped at the stop floor landing 5A, the landing call of another floor was entered in the group management control by the group management control unit 41. Occasionally, the landing call can be assigned to the car 3, but the car operation control unit 342 of the car 3 holds (stores) the driving direction information held immediately before the extension button 333 is pressed. Therefore, the landing call on another floor in the same direction as the driving direction information that is being held (in the example of this embodiment, the landing call from the landing 5 on the floor above the stop floor landing 5A: It is called "landing call of direction".) Only can be assigned.

Even if the destination button 331 is pressed in the car 3 while the car 3 is stopped at the stop floor platform 5A, the driving direction is maintained as long as the car driving control unit 342 keeps the driving direction information. Only the destination call in the same direction as the information (in the example of this embodiment, when the destination button 331 on the floor above the stop floor platform 5A is pressed: hereinafter referred to as "forward destination call") is the basket. 3 does not correspond.

Then, when the door closing is completed (step S7), if there is a forward landing call or a forward destination call, the basket 3 corresponds to these forward landing calls or forward destination floor calls. And move in the forward direction (in the example of this embodiment, it rises). Further, after the basket 3 returns to the allocation target of the group management control, a forward landing call or a forward destination call is not received and a predetermined time elapses by a predetermined time (2 seconds in the example of the present embodiment). After the lapse of time, it is referred to as a landing call on another floor in the direction opposite to the driving direction information (hereinafter referred to as "reverse landing call") or a destination floor call (hereinafter referred to as "reverse destination floor call"). ), The basket 3 moves in the opposite direction in response to the landing call in the opposite direction or the destination call in the opposite direction (descends in the example of the present embodiment). Further, if neither the landing call nor the destination floor call is entered in any direction even after the predetermined time has elapsed, the basket 3 stays at the stop floor landing 5A in the closed state.

Further, when the basket 3 arrives (stops) at the stop floor platform 5A and opens the door, the extension button 333 of the basket 3 is not pressed (that is, the detection unit 341 does not detect the press of the extension button 333). (Step S2: No), if the close button 334 is not pressed when the cage door 32 is in the door open state (fully open state), the door open state is maintained until 5 seconds have passed since the cage door 32 was fully opened. Then, 5 seconds after the close button 334 is pressed or the cage door 32 is fully opened, the cage door 32 begins to close (step S8). When the door closing is completed (step S7), the basket 3 moves (elevates) in the direction corresponding to the call, if a landing call on another floor is assigned or a destination floor call is included, and calls. If you do not enter, you will stay at the stop floor platform 5A.

According to the above elevator 1, when the car 3 stopped at the stop floor landing 5A and the extension button 333 is pressed returns to the allocation target of the group management control by the start of closing the door, the car operation control unit 342 moves in the operation direction. The information (specifically, the driving direction information held immediately before the extension button 333 is pressed) is held. Therefore, the basket 3 can respond to the forward call, and thus the decrease in the transportation efficiency of the elevator 1 can be prevented. The details are as follows.

When the extension button 333 of the basket 3 stopped at the stop floor platform 5A is pressed and the open state of the basket door 32 is maintained until the expiration of the door opening extension time (2 minutes in the example of the present embodiment), the said. The basket 3 will stop for a long time at the stop floor platform 5A. Therefore, even if a forward call is entered, another basket 3 is assigned the landing call instead of the basket (the basket stopped at the stop floor landing 5A) 3 and the landing call is entered. The transportation efficiency does not decrease toward the landing 5 (that is, the waiting time of the user at the landing 5 with the landing call is shortened).

On the other hand, when the basket 3 stopped at the stop floor platform 5A closes in a short time (shorter than the door opening extension time) by pressing the close button 334 even though the extension button 333 is pressed. , The car (the car stopped at the stop floor landing 5A) 3 may arrive at the landing 5 earlier than the other baskets 3 heading toward the landing 5 containing the landing call.

However, in the conventional elevator, if the car extension button is pressed while the car is stopped at the stop floor landing, the car (car operation control unit) does not hold the operation direction information, so that the group management control is assigned. If there is a landing call in the opposite direction or a destination floor call in the opposite direction when returning to the target, the landing call in the opposite direction or the destination floor call in the opposite direction will be answered, and the landing call in the forward direction will be accepted. I can't do it. As a result, even if it is more efficient to transport the basket (the basket with the extension button pressed) in response to the forward landing call, the basket responds to the reverse landing call or the destination floor call in the reverse direction. As a result, another basket (a basket different from the basket that stops at the stop floor landing) is assigned to the forward landing call, which reduces the transportation efficiency.

Therefore, in the elevator 1 of the present embodiment, when the extension button 333 is pressed in the basket 3 stopped at the stop floor platform 5A, when the basket 3 returns to the allocation target of the group management control by the start of door closing, the elevator 1 The car operation control unit 342 of the car 3 keeps the operation direction information immediately before the extension button 333 is pressed so as not to correspond to the landing call in the reverse direction or the destination floor call in the reverse direction, so that the order is as described above after the door is closed. It is possible to answer the landing call in the direction. That is, in the elevator 1 of the present embodiment, even if the extension button 333 is pressed, the other baskets 3 are assigned the forward landing call at the timing when the basket 3 in which the extension button 333 is pressed starts closing the door. When the transportation efficiency is improved as compared with the case where the car is stopped, the car (the car stopped at the stop floor landing 5A) 3 can respond to the forward landing call after the door is closed. As a result, it is possible to prevent a decrease in transportation efficiency in the elevator 1. If there is no forward landing call even after a predetermined time (2 seconds in the example of this embodiment) has passed after returning to the group management control allocation target, the vehicle stops at the stop floor landing 5A. By erasing the held driving direction information and holding new (reverse direction) driving direction information or rewriting the basket 3 with driving direction information in the opposite direction, the landing in the opposite direction after the door is closed. It is possible to respond to calls and destination floor calls in the opposite direction.

Moreover, when the extension button 333 is pressed in the basket 3 stopped at the stop floor platform 5A, the basket 3 operates as described above, so that the user waiting at the platform 5 on another floor sees the indicator 53. At that time, it is possible to prevent a feeling of strangeness in the movement of the basket 3 (for example, a misunderstanding that an operation abnormality (malfunction) has occurred in the elevator 1). The details are as follows.

For example, when the basket rises from the landing on the lower floor and arrives at the landing on the stop floor, when the extension button is pressed on the basket, the close button is pressed to close the door in a relatively short time. However, since the conventional elevator car does not have (delete) driving direction information when the extension button is pressed, it will stop if there is a landing call at the landing on the floor below the stop floor. Even if there is a landing call at the landing on the floor above the floor, it may go to the landing on the lower floor.

At this time, there is a user who has called for a landing at the landing on the floor above the landing on the stop floor, and this user is looking at the indicator of the landing and from the position and movement direction of the other basket, he / she goes to the landing on the stop floor. When the car that arrived was expected to come to the platform, and the basket that started moving from the stop floor platform headed (descended) to the floor below the stop floor platform, the movement (behavior) of this basket felt strange. ..

However, in the elevator 1 of the present embodiment, when the extension button 333 is pressed in the basket 3 stopped at the stop floor landing 5A, the basket operation control unit 342 returns to the allocation target of the group management control by the start of closing the door. It keeps the driving direction information immediately before pressing the extension button 333, and while holding this driving direction information, it does not correspond to the landing call in the opposite direction or the destination floor call in the opposite direction, so the door closes in a relatively short time. Then, when the elevator control device 4 returns to the allocation target of the group management control, the basket 3 corresponds to the landing call on the upper floor (the landing call entered by the user). As a result, according to the elevator 1 of the present embodiment, it is possible to manage the operation so that the user does not feel a sense of discomfort when looking at the indicator 53.

The elevator cage control device and the elevator control device of the present invention are not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. In addition, some of the configurations of certain embodiments can be deleted.

The group management control unit 41 (elevator control device 4) and the basket operation control unit 342 (cage control device 34) of the above embodiment close the basket 3 when the cage door 32 starts to close when the extension button 333 is pressed. Two seconds after returning to the allocation target of the group management control and returning to the allocation target of this group management control (after a predetermined time has elapsed), the operation direction information (operation immediately before pressing the extension button 333) that has been retained is maintained. (Direction information) is erased, but the configuration is not limited to this.

For example, in the group management control unit 41 and the car operation control unit 342, the time for holding the operation direction information immediately before the extension button 333 is pressed is the time after the extension button 333 is pressed and the cage door 32 starts to close. In the time before (that is, the time shorter than the door opening extension time: for example, the time from the start of the timer operation of the basket operation control unit 342 by pressing the extension button 333 to the time when one minute elapses). There may be. The timer may have a configuration other than the basket operation control unit 342.

Specific control by the group management control unit 41 and the basket operation control unit 342 will be described below with reference to FIG.

The basket 3 arrives at the stop floor platform 5A by the destination floor call in the last basket 3, and is stopped at the stop floor platform 5A, that is, extended by the user in the basket 3 after the door opening is completed (step S11). When the button 333 is pressed (step S12: Yes), the detection signal from the detection unit 341 that detects the pressing of the extension button 333 is input to the basket operation control unit 342. As a result, the timer of the car operation control unit 342 starts operating (step S13), and the car operation control unit 342 holds the operation direction information immediately before the extension button 333 is pressed for a further predetermined time from the detection. Continue to hold (step S14).

Subsequently, the basket operation control unit 342 outputs a request signal to the group management control unit 41, and the group management control unit 41 that receives the request signal removes the basket 3 from the allocation target of the group management control (step). S15). The order of steps S13 to S15 is not limited.

The car operation control unit 342 erases the retained operation direction information at a time (step S16: Yes) when a predetermined time (1 minute in the example of the present embodiment) has elapsed since the timer started operation (step S16: Yes). In step S17), the call in any direction (landing call and destination floor call) can be handled. In this state, when the door opening extension time (2 minutes in the example of this embodiment) elapses after the cage door 32 is fully opened without pressing the close button 334 (step S18: No) (step S19: Yes), the door is opened. Closing starts (step S20), and the basket 3 returns to the group management control allocation target (step S21).

On the other hand, when the close button 334 is pressed before a predetermined time (1 minute) has elapsed (step S16: No) after the extension button 333 is pressed and the timer starts operating in the basket operation control unit 342 (step). S18: Yes), the door closing is started (step S20), and the basket 3 returns to the allocation target of the group management control (step S21).

As in the above embodiment, in any of the above cases, the basket operation control unit 342 directs the basket operation control unit 342 toward the group management control unit 41 when the cage door 32 starts closing. A request signal for requesting the return of the basket 3 to the allocation target of the group management control is output, and the group management control unit 41 receives this request signal. In addition, the specific time during which the landing call is reassigned to the basket 3 is not limited.

When the door closing is completed (step S22), if there is a forward landing call or a forward destination call before the predetermined time elapses, the basket 3 is subjected to these forward landing calls or forward directions. It moves in the forward direction in response to the destination call of (in the example of this embodiment, it rises). In addition, if a forward landing call or a forward destination call is not received by the time the predetermined time elapses, and a reverse landing call or a destination floor call is made in the reverse direction after the predetermined time has elapsed, the basket is used. 3 moves in the opposite direction corresponding to each of these calls. Further, if neither the landing call nor the destination floor call is entered in any direction even after the predetermined time has elapsed, the basket 3 stays at the stop floor landing 5A in the closed state.

Further, when the basket 3 arrives (stops) at the stop floor platform 5A and opens the door, if the extension button 333 of the basket 3 is not pressed (step S12: No), the basket door 32 is in the door open state (fully open). If the close button 334 is not pressed in the state), the door open state is maintained until 5 seconds have passed since the cage door 32 was fully opened, and 5 after the close button 334 was pressed or the cage door 32 was fully opened. After a lapse of seconds, the cage door 32 begins to close (step S23). When the door closing is completed (step S22), the basket 3 moves (ups and downs) in the direction corresponding to the call when the landing call on another floor is assigned or the destination floor call is included. If you do not enter, you will stay at the stop floor platform 5A.

As described above, according to the elevator 1, although the basket 3 is in the open state at the stop floor platform 5A, a predetermined time from the start of the timer operation by pressing the extension button 333 (1 in the example of the present embodiment). After a lapse of minutes), the car operation control unit 342 erases the held operation direction information, whereby it becomes possible to face the landing call in the opposite direction and the destination floor call in the opposite direction. That is, a landing call in the direction opposite to the driving direction information (for example, upward) erased by the basket operation control unit 342 after a predetermined time has elapsed since the basket door 32 was fully opened by pressing the extension button 333, or a destination in the opposite direction. When a floor call is made, the basket operation control unit 342 is in a state of holding the operation direction information in the opposite direction, and moves in a direction (for example, downward) along the operation direction information in the opposite direction after the door is closed.

In the above configuration, after the extension button 333 is pressed in the basket 3 stopped at the stop floor platform 5A, the close button 334 of the basket 3 is pressed within a predetermined time from the start of operation of the timer by pressing the extension button 333. When the car 3 returns to the allocation target of the group management control, the car operation control unit 342 continues to hold the operation direction information immediately before the extension button 333 is pressed, so that the car 3 is called in the forward direction. It is possible to cope with this, thereby preventing a decrease in the transportation efficiency of the elevator 1.

Moreover, according to the elevator 1, since the car operation control unit 342 erases the driving direction information after the elapse of a predetermined time, the car 3 does not have to wait for the door to close (the door closes due to the elapse of the door opening extension time). In addition to being able to handle destination floor calls in either the up or down direction in the basket 3, it is also possible to face the landing call in either the up or down direction after the door is closed. The basket operation control unit 342 may be configured not to erase the operation direction information held after a predetermined time (a time shorter than the door opening extension time) has elapsed from the start of the timer operation.

Further, when the extension button 333 is pressed, the car control device 34 (car operation control unit 342) does not have a landing call on another floor in the same direction as the driving direction information held, and the elevator control device 4 ( When it is determined based on the information from the group management control unit 41), the driving direction information may be deleted even before the lapse of a predetermined time. According to such a configuration, when there is no forward call, the basket 3 corresponds to the reverse call even if the predetermined time has not elapsed (that is, the erased driving direction information (for example, upward direction). ) And the driving direction information (for example, downward direction) can be retained), which improves the transportation efficiency.

Further, in the elevator 1 of the above embodiment, the elevator control device 4 (group management control unit 41) performs group management control of a plurality of baskets 3, and the basket control device 34 (cage operation control unit 342) holds driving direction information and the like. ), But is not limited to this configuration. The operation management of the plurality of baskets 3 and the holding of the driving direction information may be performed by one control device.

The basket 3 of the above embodiment has two types of door open buttons (open button 332 and extension button 333), but is not limited to this configuration. The operation panel 33 may have three or more types of door open buttons having different open times. In this case, the door open button having the longest open time (set time) is the extension button 333.

Further, in the basket 3 of the above embodiment, when the extension button 333 is pressed, if the close button 334 is not pressed, the door starts to close after the set time elapses after the door is opened, but the configuration is not limited to this. .. For example, the basket 3 may be configured to maintain the open state until the close button 334 is pressed when the extension button 333 is pressed.
