Abstract

PROBLEM TO BE SOLVED: To improve service for a user by performing door closing control regardless of whether or not the user stays in a hall when detecting a situation where the user does not get into a cage from the hall. SOLUTION: In an indicating function of an arithmetic unit 20, when a hall user detected by a hall waiting detecting function is not detected in a prescribed time by an opening part user detecting function, door opening control is switched to door closing control. That is, the arithmetic unit 20 reads out a state of a user existence signal from a light receiver 5b (for the hall) and a state of a user existence signal from a light receiver 5a (for the opening part) from a RAM 27 to be compared with each other. When judging that the user of a waiting state in the hall has no boarding will from this comparing result, the arithmetic unit 20 separates the hall waiting detecting function, and the indicating function switches the door opening control to the door closing control. Therefore, even when the user has no will of getting into a cage 1, maintenance of the door opening control can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device and a control method for controlling opening / closing of an elevator door.

[0002]

2. Description of the Related Art There is a photoelectric tube door safety as a control device for safely opening and closing a door provided in an elevator cab. This photoelectric tube door safety is
It mainly comprises a light emitter, a light receiver, and a controller.

When the door is opened, the floodlight emits infrared light in a direction parallel to the door opening at or near the door opening. The light receiver detects the presence or absence of a user based on whether or not infrared light emitted by the light emitter is received.

[0004] That is, when a user of an elevator gets on or off the vehicle, the user gets on and off the vehicle passes through the door opening, so that the infrared light emitted from the light emitter is not received by the light receiver.

Therefore, this light receiver outputs a signal indicating that a user (the same applies to an obstacle) when receiving infrared light, and outputs a signal indicating that the user is present when receiving infrared light. I do.

[0006] When a signal indicating that there is a user is input from the light receiver, the control unit performs door opening control for opening the door to be closed again. That is, the photoelectric tube door safety detects the presence or absence of a user near the opening.

[0007] When it is determined that the user is in the vicinity of the opening or that the user has passed through the opening, the door opening control is performed to ensure the safety of the operation of the elevator. Is secured.

Further, some photoelectric tube door safety has a plurality of infrared optical axes (hereinafter, referred to as "multi-optical axis door safety") in order to more reliably detect the presence or absence of a user.

FIG. 11 is an upper sectional view illustrating the concept of a conventional multi-optical axis door safety. Elevator cab 1
When the doors 2a and 2b provided in the cab 1 are opened, an opening 3 is formed in the cab 1.

[0010] The multi-optical axis door safety includes a projector 4a,
4b, light receivers 5a and 5b, and a control unit 6.
For detecting the presence or absence of a user near the opening, the projector 4a
Is provided on one end side of the opening 3.

On the other hand, the light receiving device 5a is used to detect the presence or absence of a user in the hall near the opening but for the user.
Is provided on the other end side of the opening 3. This floodlight 4
a is a direction parallel to the opening 3 with respect to the light receiver 5a;
That is, the infrared ray 7a is projected in a direction parallel to the direction of the door.

When receiving the infrared ray 7a emitted by the light projector 4a, the light receiver 5a outputs a user presence / absence signal indicating that there is no user in the opening 3. When the light receiver 5a does not receive the infrared ray 7a emitted by the light projector 4a, the light receiver 5a outputs a user presence / absence signal indicating that a user is present in the opening 3.

On the other hand, in order to detect the user 8 existing in the hall before entering the car room 1 before the user 8 passes through the infrared ray 7a, the light projector 4b is moved in a direction parallel to the opening 3. An infrared ray 7b is projected from one end of the opening 3 toward the hole so as to have a predetermined angle (for example, 45 degrees) with respect to.

When the infrared receiver 7b receives the reflected infrared ray 7c obtained by reflecting the infrared ray 7b by the user 8, the light receiver 5b informs that the user 8 is present in the hall before getting into the car room 1. The user presence signal shown is output. Also,
When the reflected light 7c is not received, the light receiver 5b outputs a user presence / absence signal indicating that there is no user 8 who wants to get into the cab 1.

Here, a region where the reflected infrared ray 7c can be received by the light receiver 5b due to the presence of the user 8 is defined as a detection region 9. When at least one of the user presence / absence signals from the light receivers 5a and 5b indicates that a user is present, the control unit 6 sends a door opening signal indicating that the door is to be opened to a door control device (not shown). Output, and the doors 2a and 2b are opened.

Therefore, in this multi-optical axis door safety, not only when there is a user in the opening 3 but also when there is a user 8 in the hall trying to get into the cab 1 of the elevator, the door 2a, It is possible to open 2b.

However, if the occupancy detection function detects that the interior of the cab 1 is full, the instruction function causes the doors 2a and 2b to be closed from the door opening control regardless of the detection result of the hall waiting detection function. The control is switched to the door closing control to perform the closing.

In other words, the arithmetic unit 20 normally performs the door opening control and the door closing control based on the hall waiting detection function, but when the inside of the car room 1 is detected to be full by the full detection function, Exceptionally, the instruction function separates the hall waiting detection function and performs door closing control.

The operation of the thus configured elevator control apparatus according to the present embodiment will be described below. FIG.
FIG. 4 is a flowchart showing a process of a control unit 14 provided in the elevator control device according to the present embodiment.

First, a plurality of users are waiting in the hall, and one of the plurality of users presses the up button 18a or the down button 18b of the hall call registration device 18 to generate a hall call.

When the elevator cab 1 arrives at the hall where the hall call has occurred, the door 2a of the cab 1
2b opens. Here, it is assumed that the interior of the cab 1 is full by at least one user getting into the cab 1, and at least one other user is waiting for the next riding opportunity in the detection area 9.

In this situation, the arithmetic unit 20 of the control unit 14 first executes a fullness detection function. That is, the arithmetic unit 20 first inputs a load signal from the load detection device 13 via the load signal detection unit 19 (s1), and writes the load data A indicated by the load signal to the RAM 27 (s2).

FIG. 4 shows an example of the storage state of the RAM 27. In the RAM 27, the load data is written as a binary number as 20 kg per bit. For example, when the load data A is 2100 kg, “01101001” is written in the RAM 27 as shown in FIG.

Next, the arithmetic unit 20 reads out the full load data B from the ROM 26 (s3), obtains a value of 80% of the full load data B and sets it as a threshold value C (s4). Is written into the RAM 27 (s5).

The threshold value C is written in the RAM 27 under the same conditions as above. For example, if the threshold C is 208
In the case of 0 kg, as shown in FIG.
7, "01101000" is written.

Next, the arithmetic unit 20 reads the load data A and the threshold value C from the RAM 27 (s6) and compares them (s7). For example, as a method of comparing the load data A with the threshold value C, a method of obtaining a value obtained by subtracting the load data A from the threshold value C and determining whether the difference is 0 or more or less than 0 Applied.

If the comparison result is 0 or more, the room 1
Is determined not to be full, and if less than 0, it is determined to be full. Here, since the threshold value is 2080 kg, the load amount is 2100 kg, and the difference is −20 kg, it is determined that the cab 1 is full.

If it is determined that the cab 1 is full, the arithmetic unit 20 disconnects the hall waiting detection function,
An instruction function switches the door opening control to the door closing control. Conversely, when it is determined that the cab 1 is not full, the arithmetic unit 20 does not disconnect the hall waiting detection function,
Continue to run.

That is, the arithmetic unit 20 inputs a user presence signal from the light receiver 5b via the user presence signal detection unit 21 (s8), and based on the input user presence signal, a hole (detection area 9). ) To detect the presence or absence of a user.

As a method of detecting the presence or absence of a user in this hall, for example, a value D obtained by subtracting the user presence signal from the light receiver 5b from 1 is obtained (s9). When this value D is 0, When a user exists in the hall and the value D is 1, a method of detecting that there is no user in the hall is applied (s10).

Here, when it is detected that there is a user in the hall, the instruction function of the arithmetic unit 20 outputs a door opening signal to the RO.
M26 is read out (s11), the door opening control is performed to output the read out door opening signal to the door control device 15 via the door control output unit 22 (s12), the full capacity detection function is executed again, and the same processing is performed. Is repeated.

Conversely, when it is detected that there is no user in the hall, the instruction function of the arithmetic unit 20 reads the door closing signal from the ROM 26 (s13), and reads the read door closing signal to the door. A door closing control to output to the door control device 15 via the control output unit 22 is executed (s14).

As a result, the door in the car is closed, and the elevator movement is re-executed. As described above, in the elevator control device according to the present embodiment, whether the cab is full is detected from the load data in the cab 1, and the detection area is set when the cab 1 is full. Regardless of whether there is a user at 9 or not, the door opening control is switched to the door closing control.

Therefore, in the elevator control apparatus according to the present embodiment, even if there is a user in the hall, the door is closed when it is detected that the cab 1 is full. Is done.

[0086] Therefore, even if there is a user in the hall, the elevator movement is re-executed, so that the serviceability of the elevator to the user can be improved and the elevator can be operated quickly.

Further, although the cab 1 is full, it is possible to prevent the doors 2a and 2b of the cab 1 from being left open, thereby preventing the user from being stressed.

In the present embodiment, the CRT 17 is used as a notification device for displaying a message to the user. However, the present invention is not limited to this, and another device such as a liquid crystal display may be used. Can be.

Further, in the elevator control apparatus according to the present embodiment, the presence or absence of a user in the hall is detected by the multi-optical axis door safety. However, the present invention is not limited to this. The user in the hall can be detected.

In order to detect the presence or absence of a user in the direction parallel to the above, and to detect the presence or absence of a user of the hall, the same processing as the multi-optical axis door safety is executed, but is not limited thereto. , Various other detection methods can be applied.
Instead of infrared rays, sound waves, laser beams, or the like may be used.

Further, instead of the ROM 26 used in the present embodiment, various storage devices, for example, CD-R
OM, magnetic tape, floppy disk, magneto-optical disk, and memory card are applicable.

Similarly, instead of the RAM 27, a writable storage device, for example, a magnetic tape, a floppy disk, a magneto-optical disk, or a memory card is applicable.
Furthermore, the control unit 14 in the elevator control device according to the present embodiment can be realized by various computers such as a personal computer and a workstation.

The notifying function of the arithmetic unit 20 is to output a voice signal of “The door closes. Please wait away from the door” via the voice signal output unit 24 before the door closing control is performed. Output to the notification device 16.

Similarly, the notification function of the arithmetic unit 20 is as follows.
Before the door closing control is performed, a message signal indicating “the door closes. Please wait away from the door” is output to the CRT 17 via the message signal output unit 25.

FIG. 6 is a flowchart showing the processing of the control unit 14 provided in the elevator control device according to the present embodiment. In the processing of the control unit 14 in the present embodiment, the execution states of the full capacity detection function (u1, u2), the hall waiting detection function (u3, u4), and the instruction function (u9, u10) are the same as those in the first embodiment. Packing detection function in form (s1
To s7), the hall wait detection function (s8 to s10), and the instruction function (s11, s12 and s13, s14).

However, in the present embodiment, the notification function of the arithmetic unit 20 is executed before the door closing control by the instruction function is executed. That is, in the arithmetic device 20, the notification function is executed when the cab 1 is detected to be full by the fullness detection function, or when the waiting user in the hall is not detected by the hall waiting function detection function. .

In the notification function of the arithmetic unit 20,
First, an audio signal is read from the ROM 26 (u5), and similarly, a message signal is read from the ROM 26 (u6).
Next, the read audio signal is output to the audio signal output unit 24.

The read message signal is sent to the message signal output unit 2
5 to the CRT 17 (u8).

In the present embodiment, after the processing by the notification function, the door closing control is executed (u10). As described above, in the elevator control device according to the present embodiment, before the doors 2a and 2b of the elevator cab are closed, the user is notified that the door is closed.

Therefore, in the elevator control device according to the present embodiment, in addition to the same effects as those of the elevator control device according to the first embodiment, the safety of the user can be ensured.

Therefore, the serviceability of the elevator to the user can be further improved. In the elevator control device according to the present embodiment, the voice notification device 16 and the CRT 17 are applied as devices for notifying the user that the door is closed, but the present invention is not limited to this. When the door is closed, a lamp or the like may be turned on to notify the user that the door is closed.

(Fourth Embodiment) In the present embodiment, even if it is detected that a user is present in the hall, if the user is not detected near the opening, the use is not performed. The present invention relates to an elevator control device that determines that a person does not intend to get into a cab and closes a door.

The structure of the elevator control device according to the present embodiment is the same as that shown in FIGS. 1 and 2 shown in the first embodiment. However, in the present embodiment, the arithmetic unit 20 executes the opening-portion user detecting function.

The aperture user detection function of the arithmetic unit 20 detects the presence or absence of a user in the aperture 3 based on the user presence signal input from the light receiver 5b via the user presence signal detector 21. This is a function for detecting whether or not the user has passed through the opening 3.

Further, the arithmetic unit 20 in the present embodiment
When the user of the hall detected by the hall waiting detection function is not detected by the opening user detection function within a predetermined time, the door opening control is switched to the door closing control.

FIG. 7 is a flowchart showing the processing of the control unit 14 provided in the elevator control device according to the present embodiment. In the process of the control unit 14 in the present embodiment, first, a plurality of users are waiting in the hall, and one of the plurality of users presses the up button 18a or the down button 18b of the hall call registration device 18. A hall call occurs.

When the elevator cab 1 arrives at the hall where the hall call has occurred, the door 2a of the cab 1
2b opens. Here, it is assumed that the interior of the cab 1 is full by at least one user getting into the cab 1, and at least one other user is waiting for the next riding opportunity in the detection area 9.

In this situation, the arithmetic unit 20 of the control unit 14 first executes the hole waiting detection function. That is, a user presence / absence signal is input from the light receiver 5b (for the hall) via the user presence / absence signal detection unit 21 (v1), and the state of this user presence / absence signal is written into the RAM 27 (v1).
2).

FIG. 8 illustrates the storage state of the RAM 27. In the RAM 27, the state of the user presence / absence signal from the light receiver 5b is written in the 0th bit.

Here, since there is a user in the hole detection area 9, the state of the user presence / absence signal from the light receiver 5b is "1", and this "1" is assumed to be written. If no user is present in the hall, the light receiver 5b
Is "0", and this "0" is written to the 0th bit of the RAM 27.

Next, in the arithmetic unit 20, an opening user detection function is executed. That is, the arithmetic unit 20 inputs a user presence signal from the light receiver 5a (for the opening) via the user presence signal detection unit 21 (v3), and stores the state of the user presence signal in the first bit of the RAM 27. Write to (v
4).

Here, the cab 1 is full, and there is no user getting into the cab 1 any more.
Do not pass through. In this case, the arithmetic unit 20
The state of the user presence / absence signal received from the light receiver 5a is "0", and this "0" is written to the first bit of the RAM 27.

When it is detected that the user has passed through the opening 3, the state of the user presence signal from the light receiver 5a is "1", and this "1" is one bit of the RAM 27. Written to the eyes.

Then, the instruction function is executed in the arithmetic unit 20. That is, the arithmetic unit 20 reads the state of the user presence / absence signal from the light receiver 5b and the state of the user presence / absence signal from the light receiver 5a from the RAM 27 (v5), and compares them (v6).

For example, as a method of comparing the state of the user presence / absence signal from the light receiver 5b with the state of the user presence / absence signal from the light receiver 5a, the state of the user presence / absence signal from the light receiver 5b is A method is employed in which a value E is obtained by subtracting the state of the user presence / absence signal from the light receiver 5a, and a determination is made based on whether or not the difference E is 0.

If the result of the comparison is 0, the boarding of the user has been continued, and if it is not 0, the boarding of the user has been completed, and the user of the hall has no intention to board. Is determined.

Here, the state of the user presence / absence signal from the light receiver 5b is “1”, the state of the user presence / absence signal from the light receiver 5a is “0”, and the difference E is “1”. For,
It is determined that the user in the waiting state has no intention to enter.

As described above, when it is determined that the user in the waiting state in the hall has no intention to get in, the arithmetic unit 20 disconnects the hall waiting detection function, and the instruction function switches the door opening control to the door closing control ( v7).

Conversely, when it is determined that the user in the waiting state in the hall has the intention to get in, the arithmetic unit 20 executes the door opening control without disconnecting the hall waiting detection function, and performs the same operation. Continue processing (v
8).

As described above, in the elevator control apparatus according to the present embodiment, when it is detected that a user is present in the hall, the doors 2a and 2b are controlled to open in principle. If the user who passes through the opening 3 of the doors 2a and 2b is not detected after it is detected that there is a user in the hall, the door opening control is switched to the door closing control.

Therefore, even if the user does not intend to get into the cab 1, it is possible to prevent the door opening control from being maintained, thereby preventing the user from feeling stressed. This makes it possible to improve the serviceability of the elevator and quickly operate the elevator.

Further, even if an object detected by the hall waiting detection function is not a user but an obstacle, door-close control can be performed, so that elevator serviceability can be improved and elevators can be operated quickly. Become.

In the elevator control apparatus according to the present embodiment, it is detected whether or not a user is in the hall, and thereafter, it is determined whether or not a user who passes through the opening of the door is detected. However, the predetermined time from detecting whether or not a user is present in this hall to detecting whether or not there is a user passing through the door opening can be set arbitrarily. .

(Fifth Embodiment) In the present embodiment, whether or not the user in the hall has the intention to get into the car room 1 depends on whether or not a hall call has occurred in the opened hall. The present invention relates to an elevator control device for determining whether or not an elevator is controlled.

The control unit 14 includes a hall waiting detection function 14a, an opening user detection function 14b, and an instruction function 14.
c, the call state determination function 14d and the fullness detection function 14e are executed.

Here, the call state determination function 14d determines whether or not a hall call has occurred based on the state of the registration unit 18c of the hall call registration device in the hall where the doors 2a and 2b are opened.

The full capacity detection function 14e determines the degree of congestion in the car room 1 based on the load signal from the load detection device 13, and indicates any one of a full state, a predicted full state, and a non-full state. Is determined.

A full state is detected when the load data indicated by the load signal is larger than a preset full value. The predicted occupancy state means that the detected load data does not reach the occupancy value, but is within a predetermined range where it is likely that a user trying to get into the cab 1 will not be able to get on or not. It is detected when it is done.

The non-full state is detected when the detected load data does not reach the full value and is not within the range of the predicted full state. The operation of the elevator control device according to the present embodiment having the above configuration will be described below.

In the elevator control device, first, the cab 1
Arrives at an arbitrary hall, the door opening control is performed by the instruction function 14c. Thereafter, the doors 2a and 2b are kept open until a predetermined time elapses. However, after the predetermined time elapses, the door closing control is performed by the instruction function 14c to start the cab 1, and the cab 1 Is launched.

However, in the present embodiment, various processes are performed from the execution of the door opening operation to the execution of the door closing operation. First, in the control unit 14 in the elevator control device according to the present embodiment, the opening user detection function 1
When it is detected by 4b that there is a user near the opening 3, the door opening operation is always performed by the instruction function 14c.

At the same time, processing as shown in the flowchart of FIG. 10 is also performed. FIG. 10 shows a control unit 14 provided in the elevator control device according to the present embodiment.
It is a flowchart which shows the process of.

After the door opening control is executed (w1), the control unit 14 first detects whether or not there is a user in the hall by the hall waiting detection function 14a (w2).
Here, when the user is not detected in the hall, or when the hall waiting detection function 14a is released,
The door closing control is executed by the instruction function 14c (w
3).

On the other hand, when a user is detected in the hall, the call state determination function 14d determines whether a hall call has occurred in this hall (w).
4). If it is determined that no hall call has occurred, it is determined that there is no user who intends to get into the cab 1 in the hall, the hall wait detection function 14a is released (w5), and the hall wait detection function is resumed. 14a is executed (w2).

The hole waiting detection function 14a executed again
Is released, the door closing control is executed (w
3). If it is determined that a hall call has occurred, the fullness detection function 14e determines the congestion degree (full state, predicted full state, non-full state) in the cab 1 (w6).

When the occupancy detection function 14e determines that the occupant is in the full state, it is determined that the user cannot enter the cab 1, a warning sound is emitted (w7), and the hall waiting detection function 14a is released (w8). , Again hall waiting detection function 1
4a is executed (w2).

The hole waiting detection function 14a executed again
Is released, the door closing control is executed (w
3). When it is determined by the full load detection function 14e that the state is the predicted full state, the load invariant time, which is the time during which the load data does not fluctuate, is checked (w8). Are compared (w
9).

If the load invariant time is less than the load invariant recognition time, the load invariant time is checked again (w8), and the comparison (w9) is repeated until the load invariant period reaches the load invariant recognition time.

If the load invariant time is longer than the load invariant recognition time, it is determined that the user of the hall has no intention to get into the cab 1, the hall waiting detection function 14a is released (w5), and the hall waiting is resumed. The detection function 14a is executed (w2).

The hole waiting detection function 14a executed again
Is released, the door closing control is executed (w
3). When it is determined by the fullness detection function 14e that the state is not full, the hole waiting detection function 14e is executed again (w2).

As described above, in the elevator control apparatus according to the present embodiment, the hall waiting detection is performed based on the result of detecting whether a hall call has occurred or the result of determining the degree of congestion in the cab 1. It is determined whether to release the function 14a.

That is, in the elevator control apparatus according to the present embodiment, even if there is a user in the hall, the inside of the cab 1 is almost full or a hall call occurs in this hall. If not, the door is closed.

[0155] Therefore, even if there is a user in the hall, the elevator movement is re-executed, so that the serviceability of the elevator to the user can be improved and the elevator can be operated quickly.

Further, since the doors 2a and 2b are prevented from being left open, it is possible to prevent the user from being stressed. In the elevator control device according to the present embodiment, whether or not there is entry into the cab 1 from the hall is determined based on the presence or absence of a hall call, but is not limited thereto. Not something.

For example, the hall is provided with an image detecting device such as a camera, and the moving direction of the user in the hall is obtained from the image of the hall obtained by the image detecting device. By determining whether or not the boarding from the hall into the cab 1 may be determined.

Further, in the elevator control device according to the present embodiment, the congestion degree in the car room 1 is determined based on the load data from the load detection device 13, but the present invention is not limited to this. Absent.

For example, an image detecting device such as a camera is provided in the cab 1, an area of the user in the cab 1 is obtained based on an image obtained by the image detecting device, and the area of the area of the user is calculated. Based on this, the degree of congestion in the cab 1 may be determined.

Further, each function 14a to 14e in the control unit 14 of the elevator control device according to the present embodiment.
May be realized by software or may be realized by hardware.
