Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, an elevator car door must be closed only after a certain period of time (hereinafter referred to as "a time limit from completion of door opening. For example, set to 4 seconds") after the door is completely opened. There is. However, with this, every time the car stops on each floor, even if there are few passengers, the car cannot be closed until the above-mentioned fixed time elapses, so the operating efficiency of the car is reduced and passengers in the car are annoyed. It will be. Therefore, in order to eliminate the above problems, for example, Japanese Patent Publication No. 61
As disclosed in Japanese Patent No. 5994, use of a passenger detection device using a pair of photoelectric detection devices arranged in the vicinity of the entrance and exit of a car so that light from a light projector is blocked by passengers. Is proposed. Figure 1
6 shows.

In the figure, (1) is a landing hall, (2) is a car, (3) is an electrically driven car door, (4) is a landing door that moves in conjunction with the car door (3), (5) ( 6) is a light emitter and a light receiver arranged at the entrance of the car (2) so that passengers can block the light. As described above, when the photoelectric detection device is provided near the entrance of the car (2) and the passenger is detected due to the interruption of the light beam, the time period from the completion of the door opening is shortened, for example, from 4 seconds to 0 seconds. Then, after the light beam of the photoelectric detection device is blocked, the time during which the light beam is transmitted is for a certain period of time (hereinafter, "the time from the start of light transmission").
Say. (For example, it is set to 1 second), it is judged that the boarding / alighting is completed
(3) and the landing door (4) are closed.

By the way, there is only one passenger in the car, and the car (2)
If the inside of the car is relatively thin, the passenger getting off the car while the car door (3) is still opening, and the re-lighting time after the light is cut off by the getting-off passenger is the time limit (1 second ) Until the door is completed, the door will be closed at the same time as the door is completed, and the car will be able to quickly leave for the next floor, which is very effective in improving the operation efficiency. Needless to say, if the relighting time does not exceed the time limit (1 second) from the start of light transmission until the door is opened, the door will be closed at that time.

[0005] In addition, when there is only one passenger getting off the car, but the inside of the car (2) is crowded and the car (2) is in the back,
Even when the door is completed, the above passengers cannot get off immediately because the car (2) is crowded. However, since the door is not started to be closed until the time limit (4 seconds) from the completion of the door opening, the above-mentioned passengers can get enough time to get off and there is no fear that they will be missed.

[0006]

In the conventional elevator door control device as described above, the operation of the photoelectric detection device causes the prompt operation after completion of the door opening after a lapse of a time period (1 second) from the start of light transmission. Since the car door (3) and the landing door (4) are closed, the following problems occur.

That is, when there are two or more passengers getting off, there is no problem as long as the second passenger after the first passenger can get off immediately, but the car (2) is crowded. Moreover, when the second and subsequent passengers are in the back of the car (2), the time interval between the first passenger and the second passenger becomes long, and before the second passenger gets off, The relighting time after the first passenger got off the light beam passed the time limit (1 second) from the start of lightning, and the door started to close.

For this reason, the second and subsequent passengers want to get off but cannot get off. In particular, when the first passenger gets off near the doorway and gets off during the door-opening operation, the second and subsequent passengers will almost certainly fail to get off. That is, in the above-mentioned conventional device, various situations in which a passenger gets off, such as congestion situation in a car, a standing position of a passenger, and a door opening / closing state (during door opening operation or after door opening is completed) are taken into consideration. However, since the time limit from the start of light transmission is set uniformly, there is a problem that it is not possible to secure a sufficient dismounting time for the second and subsequent disembarking passengers.

The present invention has been made in order to solve the above-mentioned problems, and even if the inside of the car is crowded, it is possible to reduce the loss of passengers getting off the elevator door control device. The purpose is to provide.

The door opening / closing command means (17) is well known.

Next, the operation of this embodiment will be described with reference to FIGS. The flow charts shown in FIGS.
Of the car control programs stored in the memory of the microcomputer constituting the car control device (12), the door control means (12
It shows a procedure of a door control program for realizing D). Fig. 2 is a flow chart showing the overall procedure of the door control program, and Fig. 3 is a car congestion determination program (21).
Fig. 4 is a flowchart showing the procedure of the counting program (2
2 is a flow chart showing the procedure of FIG. 5, FIG. 5 is a flow chart showing the procedure of the time limit changing program (23), and FIG. 6 is a flow chart showing the procedure of the time limit operation program (24). It should be noted that the entire car control program (including the door control program) is repeatedly and periodically executed (for example, every 100 milliseconds).

First, the steps of the door control program shown in FIG.
In the basket congestion determination program of (21), the above weighing device (8)
The car load signal (8a) fetched from the car determines whether the car is crowded. This operation will be described in detail with reference to FIG.

If the car load is less than 50% at the step (31) in FIG. 3, the congestion flag CFLA in the car at the step (32).
G is set to "0" and it is determined that the car is not crowded. If the car load is 50% or more in step (31), the car congestion flag CFLAG is set to "1" in step (33), and it is determined that the car is congested. This is the operation of the in-car congestion determination program (21).

Next, the steps of the door control program of FIG.
In the counting program of (22), the elapsed time after the first getting-off passenger is detected is counted by the photoelectric detection signal (7a) fetched from the photoelectric detection device (7). This operation will be described in detail with reference to FIG.

When the car (2) is in the door closed state at step (41) in FIG. 4, the determination counter CD is set to 0.0 at step (42).
Initialize to (sec) and exit this program. Then, when the car stops in response to the call and the door starts to open, the count start determination and the count up of the determination counter CD are performed in the subsequent steps (43) to (46).

First, since the value of the judgment counter CD remains 0.0 until the first passenger is detected, the process proceeds to steps (41) → (43) → (44) → exit, and finally, Exit this program without doing anything. Next, when the first passenger is detected in a certain calculation cycle, steps (44) to (4
The process proceeds to step 5), where the counter CD is set to 0.1 in order to start counting by the determination counter CD, and the processing in this calculation cycle ends. Then, from the next calculation cycle, every time (every 0.1 (second)), steps (41) → (43) → (46) are proceeded, and the judgment counter CD is incremented by 0.1 seconds. It will be. The above is the counting program (22)
Is the operation.

Further, in the time change program of step (23) of the door control program of FIG.
In (24) (described later), the time VC1 from the start of light transmission and the time VC2 from the completion of door opening are set. This operation will be described in detail with reference to FIG.

In step (51) of FIG. 5, when the car (2) is in the door closed state, the time period VC1 and the time period V1 are exceeded in step (52).
Initialize C2 to 0.0 (seconds) and 4.0 (seconds), respectively. In addition, setting the time limit VC1 to 0.0 (seconds)
This is because in step (69) of the timed operation program (24) (FIG. 6), the door closing start timing can be determined only by the door opening completion time until the passenger is detected. That is, assuming that the time limit VC1 = 0.0, the condition “CT1 ≧ VC
1 ”will always be established, so the door closing start condition“ C
Are T1 ≧ VC1 and CT2 ≧ VC2? Is the condition "CT
Is 2 ≧ VC2? Is equivalent to

Now, when the car stops in response to a call and the door starts to open, thereafter, in steps (53) and (54), the condition for starting the door close changes from the condition based on the door open completion time to the condition based on the relighting time. The determination process for switching to step is steps (55) to (60).
Then, the process of setting the time period VC1 from the start of light transmission is repeated every cycle.

First, from the start of door opening to the detection of passengers, steps (51)-(53)-(55) -exit are executed, and the program exits without any processing. Next, when the first passenger is detected in a certain calculation cycle, the time VC2 from the completion of door opening is set to 0.0 (second) in step (54). As a result, the condition “CT2 ≧ VC2” is always satisfied, and therefore the step (6) of the timed operation program (24) (FIG. 6) is performed.
9) Door closing start condition “CT1 ≧ VC1 and CT2 ≧ V
C2? Is equivalent to the condition “CT1 ≧ VC1”.

After detecting passengers, the time limit VC2
Is 0.0, the processing of steps (56) to (60) is performed every time. First, the car is not crowded (CFLA
When G = "0") or when the car call response is not received, the process proceeds from step (56) or step (57) to step (59), in which the time period VC1 from the start of light transmission is the normal time 2 Set value VT2 (= 1.0 (seconds)) is set. On the other hand, when the inside of the car is congested (CFLAG = "1") and the car call is stopped, the value of the judgment counter CD is equal to or greater than the predetermined value VO (= 3.0 (seconds)) in step (58). It is determined whether or not. Until the predetermined time VO elapses after the first passenger is detected, in step (60), the time V
C1 is set to a first set value VT1 (= 2.5 (seconds)) which is longer than the second set value VT2 for normal use. And
After VO has passed for a predetermined time after detecting the first passenger, the time limit VC1 is again set to the second for normal time in step (59).
It is set to the set value VT2.

In this way, according to the time period changing program (23) of FIG. 2, the time period VC1 from the start of light passage and the time period VC2 from the completion of door opening are set according to the detection status of passengers. In the timed operation program of 24), it is determined whether it is time to start the door closing according to the timed VC1 and VC2, the door opening completion time, and the relighting time. This operation will be described in detail with reference to FIG.

When the car (2) is closed, the process proceeds from step (61) to step (62) where the counter CT1 representing the elapsed time (seconds) from the start of relighting and the door open. The counter CT2 indicating the elapsed time (seconds) from the completion is cleared to 0.0 (seconds) and the door closing start command flag SFLAG is reset to "0".

First, the timed operation program (24) in a normal case in which the car (2) stops in response to a car call in a state where the car load is 30% and is not crowded, and passengers get off during the door-opening operation. The operation of will be described. The relighting time counter CT1 is 0.0 (seconds) and the door opening completion time counter CT2 is 0.0 (seconds) until the first passenger is detected after the car (2) enters the door opening operation. Since there is, step (61) → (63)
→ (64) → (66) → (67) → (69) → Exit this program without processing anything. This procedure is repeated cyclically (0.1 times) until the first passenger is detected or the door is completed.
Every second).

After that, when the first passenger (getting off passenger) is detected before the completion of the door opening in a certain calculation cycle, the step is performed.
From (66), the process proceeds to step (71), where the relighting time counter CT1 is set to 0.1 in order to start counting the relighting time.
Set to (seconds). Therefore, every time from the next calculation cycle, the relighting time counter CT1 is set to 0.1 at step (68).
Count up by (seconds). As described above, in the time change program (23), when the first passenger is detected, the time VC2 is changed to 0.0 (seconds).
In 9), “CT1 ≧ VC1?” Is the door closing start condition.

Therefore, before the completion of door opening, the relighting time counter CT1 is set to the time limit VC1 (since the car is not crowded, it is set to 1.0 (second) in the time limit changing program (23)) or more. Then, from step (69) to step (7
Proceeding to 0), the door closing start command flag SFLAG is set to "1".

Further, the relighting time counter CT1 is 1.0
If the door opening is completed before (seconds) or more, immediately proceed to step (61) → (63) → (72), where the door opening completion time counter should start to count the door opening completion time. Set CT2 to 0.1 (seconds). Thereafter, as described above, the relighting time counter CT1 is counted up at step (68) and the determination at step (69) is repeated until the relighting time counter CT1 becomes 1.0 (second) or more. At the time
In step (70), the door closing start command flag SFLAG is set to "1".

When the door closing start command flag SFLAG is set to "1", the door device (9) is opened when the door opening is completed in the door opening and closing command program (well known) in step (25) of FIG. ), The door opening / closing command signal (17a) is set to "1" and output. As a result, the car door (3) and the landing door
In (4), if the door opening is completed, the door will be closed immediately, and if the door opening is not completed, the door will be opened after waiting for completion. When the door open / close command signal (17a) is once set to "1" and output to start the door close, the door open / close command signal (17a) is output as "1" until the next door open time. Keep doing

The above is the timed operation program in the normal case where the car (2) stops in response to a car call in a state where the car load is 30% and is not crowded, and passengers get off during the door opening operation (24 ) Is the operation. In addition, when the passenger gets off the vehicle after completion of the door opening, the operation is similar to the above-mentioned operation, except that the timing of switching to the door closing start condition by the relighting time is delayed. Also, the operation when responding to a hall call is similar. In this way, when the boarding / alighting ends, it is possible to close the door and depart immediately.

Next, the car (2) is stopped in response to a car call in a crowded condition with a car load of 60%, and a timed operation program (24) when a passenger near the doorway first gets off during door opening operation ) Operation will be described. When the first passenger is detected after the door is opened, the car call is answered in a crowded condition with a car load of 60%.
In 3), the time period VC1 from the start of light transmission is set to 2.5 (seconds), and the time period VC2 from the completion of door opening is set to 0.0 (seconds). Therefore, a predetermined time V0 (= 3.
Until the time (0 seconds) has elapsed, the re-lighting time counter CT1 must be 2.5 (seconds) or more in step (69) to determine the door closing start.

Therefore, as shown in FIG.
1) to (P4), more than 2 people, and the second and subsequent passengers (P2)
Even if the time interval between the first passenger (P1) and the second passenger (P2) becomes long when (P4) is in the back of the car, the second set value VT1 (= 2.5 (second )) Will be secured for the sufficient dismounting time, so the second and subsequent passengers (P2) ~
(P4) can get off with plenty of time.

After that, when it can be determined that the second and subsequent passengers are getting off, that is, when a predetermined time V0 (= 3.0 seconds) has passed since the first getting-off passenger was detected, Since the time limit VC1 from the start of light transmission is changed to 1.0 (seconds) by the above time change program (23), after that, in the step (69), as in the case where the car is not crowded. Relighting time counter CT1 is 1.0
If it exceeds (seconds), it will be decided to start closing the door. As a result, as shown in FIG. 7, when the last passenger (P4) gets off, the door can be closed promptly.

As described above, in the first embodiment, when it is determined that the car is stopped and the car (2) is congested, a predetermined time V0 is detected after the first getting-off passenger is detected.
Until the time (= 3.0 seconds) elapses, the time limit from the start of light transmission is set to a value longer than usual (= 2.5 seconds), and after the predetermined time V0 has elapsed, the time limit from the start of light transmission is set. The normal value (= 1.0 seconds) is set. As a result, the first passenger is detected even if the passengers near the doorway get off during the door-opening operation and the second and later passengers at the back of the car cannot get off after the first passenger. After that, we will delay the door closing by the time limit VC1 (= 2.5 seconds) to secure the exit time, so there is no concern that the second and subsequent passengers will be missed.

In the first embodiment described above, the condition for determining that the second and subsequent passengers have been getting off is a predetermined time V0 (= 3.0 seconds) after the first passenger is detected. However, the value of the predetermined time V0 is not limited to this. For example, if the inside of the car is extremely crowded, set a large value such as V0 = 4.0, and if the inside of the car is not very crowded, set a small value such as V0 = 2.0. The value of the predetermined time V0 may be set according to the degree of congestion.

In the first embodiment, the first set value VT1
Is set to a value slightly smaller than the predetermined time V0, but it does not necessarily have to be decreased. First set value VT1
There is no problem even if is set to a value larger than the predetermined time V0. In short, a value that can secure a time that does not prevent the second and subsequent passengers from failing to get off is sufficient.

Embodiment 2 FIGS. 8 to 9 show a second embodiment of the present invention.
It is a figure which shows one Example of invention of this. FIG. 8 corresponds to FIG. 4 of the first embodiment, and is a flowchart showing the procedure of the counting program (22), and FIG. 9 is an operation explanatory diagram corresponding to FIG. 7 of the first embodiment. 1 to 3, FIG. 5 of the first embodiment,
6 and FIG. 6 are used as they are, but the counting means (13) (FIG. 1) in the second embodiment counts the elapsed time after the door is opened for a predetermined width or more and outputs it as a count signal (13a). And Further, the counting program (22) shown in FIG. 9 is obtained by implementing the counting means (13) by a program of a microcomputer.

Next, the operation of the second embodiment will be described with reference to FIGS.
This will be described with reference to FIGS. 5, 6, 8 and 9. In the door control program of FIG. 2, the operation of the in-car congestion determination program of step (21) is the same as that described in the first embodiment, so description thereof will be omitted and the counting program (22) of the next step (22) will be omitted. The operation will be described in detail with reference to FIG.

If the car (2) is in the door closed state at step (91) in FIG. 8, the judgment counter CD is set to 0.0 at step (92).
Initialize to (sec) and exit this program. Then, when the car (2) stops in response to the call and the door starts to open,
After that, in step (93) and step (94), the judgment counter CD
The count start determination and count up are performed.

First, since the value of the judgment counter CD remains 0.0 until it is detected that the door opening width has reached the 80% door opening position after starting the door opening, step (91) → ( 93) → Proceed to the exit and eventually exit this program without processing anything. Next, when it is detected that the door opening width has become 80% or more in a certain calculation cycle, the process proceeds from step (93) to step (94), where the counter CD is set to start counting by the determination counter CD. The value is set to 0.1, and the processing in this calculation cycle is completed. Then, from the next calculation cycle, every time (every 1.0 seconds), steps (91) → (93) → (94) are performed,
Here, the judgment counter CD is incremented by 1.0 seconds. The above is the operation of the counting program (22).

Next, in the time change program of step (21) in FIG. 2, the time change operation program (2
Set the time limit VC1 from the start of light transmission and the time limit VC2 from the completion of door opening used in 4). In the second embodiment, the predetermined time V0 in step (58) of FIG. 5 is 3.0.
It is assumed that it is set to 2.0 (seconds) instead of (seconds).

Therefore, in the time change program (23) in the second embodiment, when a passenger is detected, the door opening start condition is switched from the condition based on the door opening completion time to the condition based on the relighting time, and the car (2 ) When the inside is crowded, the car call is stopped, and more than 80% of the doors have been opened for less than the predetermined time V0, the time VC1 from the start of light transmission is for normal time The first set value VT longer than the second set value VT2 (= 1.0 (seconds)) of
1 (= 2.5 (seconds)), and in the states other than the above, the time period VC1 from the start of light transmission is set to the second set value VT2.

In this way, the time period changing program (23) of FIG. 2 sets the time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening, but in the time period operation program of step (24), It is determined whether it is time to start the door closing according to the time periods VC1 and VC2, the door opening completion time, and the relighting time. This operation will be described in detail with reference to FIG.

The operation of the door control program in a normal case in which the car stops in response to a car call in a state where the car is not congested with a car load of 30%, for example, and passengers get off during the door opening operation, is described in the embodiment. Since the operation is the same as that described in 1, the description will be omitted. The same applies to the case where the passenger dismounts after completing the door opening, or when the passenger answers the hall call. Thus, when the inside of the car (2) is not crowded, it is possible to immediately close the door and depart when the boarding / alighting ends.

Next, when the car is stopped in response to a car call in a congested condition with a car load of 60%, a timed operation program (2
The operation of 4) will be described. When the first passenger gets in and out after the door is opened, the car call is answered in a crowded state with a car load of 60%, so the time VC1 from the start of light transmission in the above time change program (23) is 2. 5 (seconds), the time limit VC2 after completion of door opening is set to 0.0 (seconds). Therefore, a predetermined time V0 (= 2.0
Re-lighting time C in step (69) until
If T1 does not exceed 2.5 (seconds), it will not be decided to start closing the door.

Therefore, as shown in FIG.
1) to (P4), more than 2 people, and the second and subsequent passengers (P2)
Even if the time interval between the first passenger (P1) and the second passenger (P2) becomes long when (P4) is in the back of the car, the second set value VT1 (= 2.5 (second )) Will be secured for the sufficient dismounting time, so the second and subsequent passengers (P2) ~
(P4) can get off with plenty of time.

After that, when it can be determined that the second and subsequent passengers will be getting off subsequently, that is, a predetermined time V0 (= 3.0) after it is detected that 80% or more of the passengers have been opened.
Seconds), the time limit VC1 from the start of light transmission is changed to 1.0 (seconds) by the above time change program (23), so after that, it is the same as when the car is not crowded In step (69), when the relighting time CT1 becomes 1.0 (seconds) or more, it is decided to start closing the door. As a result, as shown in FIG. 9, when the last passenger (P4) gets off, the door can be closed promptly.

As described above, in the second embodiment, when it is determined that the car has stopped due to the call and the car (2) is congested, it is determined that 80% or more of the doors have been opened, and then predetermined Until the time V0 (= 2.0 seconds) elapses, the time limit from the start of light transmission is set to a value longer than usual (= 2.5 seconds), and after the predetermined time V0 elapses, light transmission is started. The time limit from the start is set to a normal value (= 1.0 seconds). As a result, the first passenger is detected even if the passengers near the doorway get off during the door-opening operation and the second and later passengers at the back of the car cannot get off after the first passenger. After that, we will delay the door closing by the time limit VC1 (= 2.5 seconds) to secure the exit time, so there is no concern that the second and subsequent passengers will be missed.

In the second embodiment, the condition for determining that the second and subsequent passengers are expected to be alighting subsequently is 8
Although it is assumed that the predetermined time V0 (= 2.0 seconds) has elapsed since the door was opened by 0% or more, the value of the predetermined time V0 is not limited to this. For example, if the inside of the car (2) is very crowded, set a large value such as V0 = 4.0, and the car (2)
If the inside is not so crowded, set a small value such as V0 = 1.5, and set a predetermined time V0 depending on the degree of congestion.
You may make it set the value of.

Further, the door opening width as a reference for counting the elapsed time is not limited to 80%, and the door opening width which allows passengers to get off may be selected as a reference for each door device.

Embodiment 3 FIGS. 10 and 11 are views showing an embodiment of the third invention of the present invention. FIG. 10 corresponds to FIG. 4 of the first embodiment, and is a flow chart showing the procedure of the counting program (22), and FIG. 11 is an operation explanatory diagram corresponding to FIG. 7 of the first embodiment. Although FIGS. 1 to 3, 5, and 6 of the first embodiment are used as they are, the counting means (13) (FIG. 1) in the third embodiment detects the passengers and then the next passenger. It is assumed that the elapsed time until the detection of is detected is counted and this is output as a count signal (13a). further,
The counting program (22) shown in FIG. 10 is one in which the counting means (13) is realized by a microcomputer program.

Next, the operation of the third embodiment will be described with reference to FIGS.
This will be described with reference to FIGS. 5, 6, 10, and 11.
In the door control program of FIG. 2, the operation of the in-car congestion determination program of step (21) is the same as that described in the first embodiment, so description thereof will be omitted and the counting program (22) of the next step (22) will be omitted. The operation will be described in detail with reference to FIG.

If the car (2) is in the door closed state at step (111) in FIG. 10, the judgment counter CD is set to 9 at step (112).
The auxiliary counter CDX is initialized to 0.0 (seconds) at 9.9 (seconds), and this program exits. And a basket
When (2) stops in response to the call and the door starts to open, the count start determination and count up of the auxiliary counter CDX and the determination counter C are performed in steps (113) to (119).
Set D.

First, since the value of the auxiliary counter CDX remains 0.0 until the first passenger is detected after the door is opened, steps (111) → (113) → (116) → (118). → Proceed to the exit and exit this program without doing anything.
Next, when the first passenger gets on and off in a certain calculation cycle, the process proceeds to steps (111) → (113) → (116) → (117), and step (11)
In step 7), the auxiliary counter CDX is set to 0.1 in order to start counting by the auxiliary counter CDX, and the processing in this calculation cycle is completed.

Since the photoelectric detection signal (7a) is normally "1" for several hundred milliseconds, in the next several operation cycles, steps (111) → (113) (CDX> 0. 0)
→ (114) → (116) → (117) and the auxiliary counter CDX is continuously set to 0.1 at step (117) every time. When the first passenger is detected, the process of step (115) is not performed because the photoelectric detection signal (7a) has already passed the rising timing from "0" to "1".

Now, when the first passenger gets off the vehicle and the photoelectric detection signal (7a) becomes "0" again, this time step (11)
1) → (113) (CDX> 0.0) → (114) → (116) → (118), and the judgment counter CD is set to 0.1 in step (118).
Count up by (seconds).

Next, when the second passenger gets off, steps (111) → (113) (CDX> 0.0) → (114)
Here, the rising edge of the photoelectric detection signal (7a) (“0” →
"1") is detected, the process further proceeds to step (115), where the smaller of the value of the auxiliary counter CDX and the value of the determination counter CD set up to that point is newly determined. Set to. After that, as described above, the steps (115) → (116) → (117) are proceeded, the auxiliary counter CDX is set to 0.1 again, and the counting is started. The smaller value is set in step (115) because the time change program (23) once sets the second set value to the time period VC1 and then the time period VC1 is set to the original first set value again. This is to avoid returning to.

Similarly, the time intervals of the second and third alighting passengers and the time intervals of the third and fourth alighting passengers are counted, and a new value is set in the determination counter CD each time. . The above is the operation of the counting program (22).

Next, in the time change program of step (23) in FIG. 2, the time operation program (24) is the same as in the first embodiment.
The time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening are set. In the third embodiment, the predetermined time V0 in step (58) of FIG. 5 is set to 1.2 (seconds) instead of 3.0 (seconds), and the judgment condition is also "the judgment counter is a predetermined value." Is it greater than or equal to? CD≥V0 ?, not "Is the judgment counter below a predetermined value? CD≤V0
? ".

Therefore, in the time period changing program (23) in the third embodiment, when the passenger is detected, the door opening start condition is switched from the condition based on the door opening completion time to the condition based on the relighting time, and the car (2) The inside is crowded,
When the call to the car is stopped and the time between passengers getting off exceeds the predetermined time V0, the time limit VC1 from the start of light transmission
Is set to a first setting value VT1 (= 2.5 (seconds)) longer than the second setting value VT2 (= 1.0 (seconds)) for normal operation. The time limit VC1 is set to the second set value VT2.

In this way, the time period changing program (23) of FIG. 2 sets the time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening, but in the time period operation program of step (24), It is determined whether it is time to start the door closing according to the time periods VC1 and VC2, the door opening completion time, and the relighting time. This operation will be described in detail with reference to FIG.

The operation of the door control program in the normal case where the car (2) stops in response to a car call in a state where the car (2) is not congested with a car load of 30%, and passengers get off during the door opening operation Since the operation is the same as that described in the first embodiment, a description thereof will be omitted. The same applies to the case where the passenger dismounts after completing the door opening, or when the passenger answers the hall call. Thus, when the inside of the car (2) is not crowded, it is possible to immediately close the door and depart when the boarding / alighting ends.

Next, the car (2) is stopped in response to a car call in a crowded condition with a car load of 60%, and a timed operation program (24) when a passenger near the doorway first gets off during door opening operation ) Operation will be described. When the first passenger is detected after the door is opened, the car call is answered in a crowded condition with a car load of 60%.
In 3), the time period VC1 from the start of light transmission is set to 2.5 (seconds), and the time period VC2 from the completion of door opening is set to 0.0 (seconds). Therefore, the detection interval of passengers is V0 (= 1.2 seconds)
Until it becomes the following, in step (69), the re-lighting time CT1 must be 2.5 seconds or more to determine the start of door closing.

Therefore, as shown in FIG.
Two or more passengers from (P1) to (P4), and the second and subsequent passengers (P
Even if 2) to (P4) are behind the car (2) and the time interval between the first passenger (P1) and the second passenger (P2) becomes long,
The second set value VT1 (= 2.5 (seconds)) will be sufficient for the dismounting time, so the second and subsequent disembarking passengers
From (P2) to (P4), you can get off with plenty of time.

After that, when it is detected that the second and subsequent passengers are getting off, that is, the time interval from the detection of a passenger to the detection of the next passenger is a predetermined time V.
When it becomes 0 (= 1.2 seconds) or less, the time period VC1 from the start of light transmission is 1.0 due to the time period changing program (23) described above.
Since it is changed to (second), after that, as in the case where the inside of the car (2) is not crowded, when the relighting time CT1 becomes 1.0 (second) or more in step (69), it will be closed. It will decide the start. Thereby, as shown in FIG. 11, when the last passenger (P4) gets off, the door can be closed promptly.

As described above, in the third embodiment, when it is determined that the car is stopped and the car (2) is congested, the passenger detection interval is the predetermined time V0 (= 1. 2 seconds)
While the time is over, the time limit from the start of light transmission is set to a value longer than usual (= 2.5 seconds), and when the predetermined time V0 or less is reached thereafter, the time limit from the start of light transmission is set to the normal value (= 1.0
Seconds). As a result, even if the passengers near the doorway get off during the door-opening operation and the second and later passengers in the back of the car (2) cannot get off after the first passenger, After the passenger is detected, the door closing time is further delayed by the time VC1 (= 2.5 seconds) to secure the exit time, so there is no concern that the second and subsequent passengers will be missed.

In the third embodiment, the condition for detecting that the second and subsequent passengers are getting off is as follows: the detection interval of passengers is less than the predetermined time V0 (= 1.2 seconds). However, the value of the predetermined time V0 is not limited to this. Depending on the type of door device, for example, when the door opening width is wide, it becomes easier to get off the car continuously, so set V0 = 0.8 (seconds) short, and conversely when the door opening width is narrow, V0 = 1.4.
An appropriate value may be set as appropriate, such as a longer setting (seconds).

Embodiment 4 FIGS. 12 to 13 are views showing an embodiment of the fourth invention of the present invention. 12 is a flowchart corresponding to FIG. 4 of the first embodiment, showing a procedure of the counting program (22), and FIG. 13 is an operation explanatory diagram corresponding to FIG. 7 of the first embodiment. Although FIGS. 1 to 3, 5, and 6 of the first embodiment are used as they are, the counting means (13) (FIG. 1) in the fourth embodiment counts the number of passengers alighted from the car (2). Then, this is output as a count signal (13a). Further, the counting means (13) realized by a microcomputer program is a counting program (2
2).

Next, the operation of the fourth embodiment will be described with reference to FIGS.
This will be described with reference to FIGS. 5, 6, 12, and 13. In the door control program of FIG. 2, the operation of the in-car congestion determination program of step (21) is the same as that described in the first embodiment, so description thereof will be omitted and the counting program (22) of the next step (22) will be omitted. The operation will be described in detail with reference to FIG.

If the car (2) is in the door closed state at step (131) in FIG. 12, the determination counter CD is reset to 0 at step (132).
Initialize to (times) and exit this program. Then, when the car (2) stops in response to the call and the door starts to open,
After that, in step (133) and step (134), the judgment counter C is used.
A count start determination and a count up of D are performed.

First, after the door is opened, the value of the judgment counter CD remains 0 (times) until the rise of the photoelectric detection signal (7a) ("0" → "1") is detected. (13
Go to 1) → (133) → exit and exit this program without any processing. Next, when the rising edge (“0” → “1”) of the photoelectric detection signal (7a) is detected in a certain calculation cycle, the process proceeds from step (133) to step (134), where the judgment counter CD is set to 1 ( () Times, and the processing in this calculation cycle ends. Then, from the next calculation cycle, step again until the condition of step (133) is satisfied.
From (131) → (133) → exit, you will exit this program without processing anything. The above is the counting program (22)
Is the operation.

Next, in the time change program of step (23) in FIG. 2, the time change operation program (2
Set the time limit VC1 from the start of light transmission and the time limit VC2 from the completion of door opening used in 4). In the fourth embodiment, the predetermined time V0 in step (58) of FIG. 5 is 3.0.
It is assumed that 3 (times) is set instead of (seconds).

Therefore, in the time limit changing program (23) in the fourth embodiment, when a passenger is detected, the door opening start condition is switched from the condition based on the door opening completion time to the condition based on the relighting time, and the car (2 ) Is crowded, the car call is stopped, and the number of passengers detected is less than the specified value V0, the time V from the start of light transmission is V
C1 is the second setting value VT2 for normal time (= 1.0 (seconds))
Is set to a longer first set value VT1 (= 2.5 (seconds)), and in the states other than the above, the time limit VC1 from the start of light transmission is set.
Is set to the second set value VT2.

In this way, the time period changing program (23) of FIG. 2 sets the time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening, but in the time period operation program of step (24), It is determined whether it is time to start the door closing according to the time periods VC1 and VC2, the door opening completion time, and the relighting time. This operation will be described in detail with reference to FIG.

The operation of the door control program in the normal case in which the car stops in response to a car call in a state where the car is not congested with a car load of 30% and the passenger gets off during the door opening operation, Since the operation is the same as that described in 1, the description will be omitted. The same applies to the case where the passenger dismounts after completing the door opening, or when the passenger answers the hall call. Thus, when the inside of the car (2) is not crowded, it is possible to immediately close the door and depart when the boarding / alighting ends.

Next, when the car is stopped in response to a car call in a crowded condition with a car load of 60%, the timed operation program (2
The operation of 4) will be described. When the first passenger gets in and out after the door is opened, the car call is answered in a crowded state with a car load of 60%, so the time VC1 from the start of light transmission in the above time change program (23) is 2. 5 (seconds), the time limit VC2 after completion of door opening is set to 0.0 (seconds). Therefore, until the number CD of detections of passengers is equal to or greater than the predetermined value V0 (= 3 times), the re-lighting time CT1 is not determined to be 2.5 (seconds) or more in step (69) to determine the door closing start. It will be.

Therefore, as shown in FIG.
Two or more passengers from (P1) to (P4), and the second and subsequent passengers (P
Even if 2) to (P4) are behind the car and the time interval between the first passenger (P1) and the second passenger (P2) becomes long,
A sufficient dismounting time of the set value VT1 (= 2.5 (seconds)) will be secured, so the second and later disembarking passengers (P2)
~ (P4) can get off with plenty of time.

After that, when it is detected that the second or later scheduled number of passengers have got off, that is, when the number of passengers detected CD is equal to or more than a predetermined value V0 (= 3 times),
Since the time limit VC1 from the start of light transmission is changed to 1.0 (seconds) by the above time change program (23), after that, as in the case where the inside of the car is not crowded, the step (6
In 9), when the relighting time CT1 becomes 1.0 (seconds) or more, it is decided to start the door closing. As a result, FIG.
As shown in, when the last passenger (P4) gets off, the door can be closed promptly.

As described above, in the fourth embodiment, when it is determined that the car is stopped and the car (2) is congested, the number CD of passengers detected is a predetermined value V0 (= 3). Times)
Until the above, the time period from the start of light transmission is set to a value longer than usual (= 2.5 seconds), and when the number of passengers detected is equal to or greater than the predetermined value V0, light transmission is started. The time limit of is set to a normal value (= 1.0 second).
As a result, even if the passengers near the doorway get off during the door-opening operation and the second and later passengers in the back of the car (2) cannot get off after the first passenger, After the passenger is detected, the door closing time is further delayed by the time VC1 (= 2.5 seconds) to secure the exit time, so there is no concern that the second and subsequent passengers will be missed.

In the above-mentioned fourth embodiment, the condition for detecting that the second and subsequent scheduled passengers have got off is that the number of passengers detected CD after opening the door is equal to or greater than a predetermined value V0 (= 3 times). However, the value of the predetermined value V0 is not limited to this. For example, if the car (2) is very crowded, set V0 = 4 and a large value, and if the car (2) is not very crowded, set V0 = 2 and a small value. For example, the value of the predetermined value V0 may be set according to the degree of congestion.

In the fourth embodiment, the photoelectric detection device (7)
Although the number of passengers getting off is detected by the number of times the rays of light are blocked, the means for detecting the number of getting off passengers is not limited to this. For example, the cage load signal (8a) of the balance device (8)
The number of passengers getting off is calculated by the amount of change (the amount decreased from the car load before opening the door), or the passengers are individually identified by image-processing the image of the TV camera installed in the car (2), The passengers and the alighting passengers may be distinguished and counted from the moving direction, or the number of alighting passengers may be detected by a sensor using ultrasonic waves or infrared rays.

Example 5 In the above Examples 3 and 4,
The photoelectric detection device (7) sets the conditions for changing the time limit VC1 almost in the expectation that it will operate once for each passenger, but it looks like a car with a wide door opening (2). If a couple of people get off when getting off, it is hard to say that the change conditions are appropriate. In this case, it is known that the number of times the light is blocked by the photoelectric detection device (7) is reduced, and conversely the time during which the light is blocked becomes longer. In consideration of this point, it is a fifth embodiment to be described below to reduce the loss of the second and subsequent passengers getting off.

14 and 15 are diagrams showing an embodiment of the fifth invention of the present invention. FIG. 14 is a diagram of FIG.
15 is a flow chart showing the procedure of the counting program (22), and FIG. 15 is an operation explanatory diagram corresponding to FIG. 7 of the first embodiment. 1 to 3, 5, and 6 of the first embodiment are used as they are, the photoelectric detection device (7) operates in the counting means (13) (FIG. 1) in the fifth embodiment. It is assumed that time is counted and this is output as a count signal (13a). Further, the counting program (22) of FIG. 14 is realized by the program of the microcomputer for the counting means (13).

Next, the operation of the fifth embodiment will be described with reference to FIGS.
This will be described with reference to FIGS. 5, 6, 14, and 15.
In the door control program of FIG. 2, the operation of the in-car congestion determination program of step (21) is the same as that described in the first embodiment, so description thereof will be omitted and the counting program (22) of the next step (22) will be omitted. The operation will be described in detail with reference to FIG.

When the car (2) is in the door-closed state at step (151) in FIG. 14, the determination counter CD is set to 0 at step (152).
Initialize the auxiliary counter CDX to 0 (seconds) to 0.0 (seconds), and exit this program. And a basket (2)
Stops in response to the call and the door starts to open
In (153) to step (155), the count start determination and count-up of the auxiliary counter CDX and the determination counter CD are set.

First, the process proceeds to steps (151) → (153) → (155) until the first passenger is detected after the door is opened and the value of the auxiliary counter CDX is set to 0.0 every time. Reset. Next, if the first passenger is detected in a certain calculation cycle, the process proceeds to step (151) → (153) → (154), and step (154)
At the same time when the auxiliary counter CDX starts counting,
The value of the judgment counter CD that has been set up to that point is compared with the value of the auxiliary counter CDX, and the larger value is newly set in the judgment counter CD. It should be noted that the reason why the larger value is set in this way is that the time change VC (1) once sets the second set value in the time limit VC1 and then returns the time set VC1 to the original first set value again. This is to ensure that there is no

Then, in the calculation cycle while the photoelectric detection signal (7a) is "1", steps (151) → (153) → (15
In step (154), the auxiliary counter CDX is counted up and the judgment counter CD is set in step (154). When the passengers are no longer detected, the value of the auxiliary counter CDX is reset to 0.0 every time in step (155). Similarly, the photoelectric detection device is used for the second time and thereafter.
The operation time of (7) is counted, and a new value is set in the determination counter CD each time. The above is the operation of the counting program (22).

Next, in the time change program of step (23) in FIG. 2, the time operation program (24) is the same as in the first embodiment.
The time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening are set. In the fifth embodiment, it is assumed that the predetermined time V0 in step (58) in FIG. 5 is set to 1.5 (seconds) instead of 3.0 (seconds).

Therefore, in the time period changing program (23) in the fifth embodiment, when a passenger is detected, the door opening start condition is switched from the condition based on the door opening completion time to the condition based on the relighting time, and the car (2) The inside is crowded,
Until the operation of the photoelectric detection device (7) exceeds a predetermined time V0, the time VC1 from the start of light passage is the second set value VT2 (= 1.0) for normal time until the car call is stopped.
(Second)) longer than the first set value VT1 (= 2.5
(Second)), and in the states other than the above, the time period VC1 from the start of light transmission is set to the second set value VT2.

In this way, the time period changing program (23) in FIG. 2 sets the time period VC1 from the start of light transmission and the time period VC2 from the completion of door opening, but in the time period operation program of step (24), It is determined whether it is time to start the door closing according to the time periods VC1 and VC2, the door opening completion time, and the relighting time. This operation will be described in detail with reference to FIG.

The operation of the door control program in the normal case that the car (2) stops in response to a car call in a state where the car (2) is not congested with the car load of 30%, and passengers get off during the door opening operation Since the operation is the same as that described in the first embodiment, a description thereof will be omitted. The same applies to the case where the passenger dismounts after completing the door opening, or when the passenger answers the hall call. Thus, when the inside of the car (2) is not crowded, it is possible to immediately close the door and depart when the boarding / alighting ends.

Next, the car (2) is stopped in response to a car call in a crowded condition with a car load of 60%, and a timed operation program (24 ) Operation will be described. When the first passenger is detected after the door is opened, the car call is answered in a crowded condition with a car load of 60%.
In 3), the time period VC1 from the start of light transmission is set to 2.5 (seconds), and the time period VC2 from the completion of door opening is set to 0.0 (seconds). Therefore, the operation time of the photoelectric detection device (7) is the predetermined time V0 (=
Until the re-lighting time CT1 becomes 2.5 (seconds) or more in step (69) until it exceeds 1.5 seconds, the door closing start is not decided.

Therefore, as shown in FIG.
Two or more passengers from (P1) to (P4), and the second and subsequent passengers (P
Even if 2) to (P4) are behind the car (2) and the time interval between the first passenger (P1) and the second passenger (P2) becomes long,
The second set value VT1 (= 2.5 (seconds)) will be sufficient for the dismounting time, so the second and subsequent disembarking passengers
From (P2) to (P4), you can get off with plenty of time.

After that, when it is detected that the second and subsequent passengers are getting stuck and getting off, that is, the time during which the passengers are continuously detected (the time when the photoelectric detection device (7) continues to operate) is predetermined. When the time V0 (= 1.5 seconds) is exceeded, the time limit V from the start of light transmission by the above-mentioned time limit change program (23)
Since C1 is changed to 1.0 (seconds), after that,
Just like when the car (2) is not crowded,
In 9), when the relighting time CT1 becomes 1.0 (seconds) or more, it is decided to start the door closing. As a result, FIG.
As shown in, when the last passenger (P4) gets off, the door can be closed promptly.

As described above, in the fifth embodiment, when it is determined that the car is stopped and the car (2) is crowded, the time during which the passengers are continuously detected is a predetermined time V0.
During the time (= 1.5 seconds) or less, the time limit from the start of light transmission is set to a value longer than usual (= 2.5 seconds), and after that, when the predetermined time V0 or less is reached, the time limit from the light transmission start is set. The normal value (= 1.0 seconds) is set. As a result, even if the passengers near the doorway get off during the door-opening operation and the second and later passengers in the back of the car (2) cannot get off after the first passenger, After the passenger is detected, the door closing time is further delayed by the time VC1 (= 2.5 seconds) to secure the exit time, so there is no concern that the second and subsequent passengers will be missed.

In the fifth embodiment, the condition for detecting that the second and subsequent passengers are getting off is fixed as the predetermined time V0 (= 1.5 seconds) while the passengers are continuously detected. However, the value of the predetermined time V0 is not limited to this. Depending on the type of door device, for example, when the door opening width is wide, it becomes easier to get off in line, so V0 = 1.0
(Seconds) and set a little shorter, and when the door opening width is narrow, conversely V0
= 2.0 (seconds), for example, a longer value may be set as appropriate.

Further, in the fifth embodiment, the operation time of the photoelectric detection device (7) is re-counted each time the passenger is detected. However, the cumulative value of the operation time is calculated and the accumulated operation is performed. It is also easy to compare the time and the predetermined time V0 to determine the value to be set in the time limit VC1. In addition,
In this case, since the cumulative operation time corresponds to the number of passengers getting on and off, it is equivalent to the fourth embodiment in which the condition for changing the time limit VC1 is that a predetermined number of passengers get off.

Example 6 In the above Examples 1 to 5,
The weighing device (8) provided on the floor of the car (2) is used to detect the congestion in the car (2), but the means for detecting the congestion in the car (2) is not limited to this. For example, a device that detects the degree of congestion by performing image processing on the image of a television camera provided in the car, or a device that detects the number of passengers with a sensor that uses ultrasonic waves or infrared rays may be used.

Further, the reference value of the car load for determining whether the inside of the car is crowded is set to 50%, but the reference value is not limited to this. It is desirable to determine the above reference values as appropriate according to the purpose of the building in which the elevator is installed and the number of customers.

Example 7 Also, the above Examples 1 to 5
Then, the photoelectric detection device (7) is used as the passenger detection device for detecting the passengers getting on and off, but the present invention is not limited to this. It may be a passenger detection device that uses a sensor that uses ultrasonic waves or infrared rays, or a device that processes an image of a television camera image.

Example 8 Also, the above Examples 1 to 5
It is also easy to carry out by arbitrarily combining the time change conditions. In this case, since it is possible to make a detailed determination by making use of the characteristics of each timed changing condition, a further excellent effect can be expected.

Embodiment 9 Furthermore, in the above Embodiments 1 to 5, the case where one car (2) is arranged is shown, but also when two or more group management elevators are installed. It is obvious that this invention can be applied.
