Put the lower end that h4 is detected body 7.Herein, line La of the car 1 in the reference position of position detector 8 becomes position h2 and position
During the centre position h0 of h3, in being stopped in layers in the state of correct position.
Elevator control gear 20 is for example in the case where making car 1 stop at defined layer in decline, in 2 light-receivings
Device 81,82 not light at the time of detect out position h1, out position h2 is detected at the time of 83 not light of optical receiver in addition.From inspection
From at the time of measuring position h2, make car 1 it is further mobile as defined in distance, so as to which elevator control gear 20 makes car 1 exist
Position h0 stops.
In the case where car 1 is made to stop at defined layer in rising, elevator control gear 20 is equally based on 3 optical receivers
81st, 82,83 state comes test position h4 and h3, and from detect position h3 at the time of, make the further mobile regulation of car 1
Distance, so as to elevator control gear 20 make car 1 position h0 stop.
Make car 1 after position h0 stoppings in elevator control gear 20, the flat bed instruction department 24 of elevator control gear 20 into
Row flat bed controls.At this point, output of the flat bed instruction department 24 using impulse generator 4, based on 21 operations of car position operational part
The position of car 1 gone out, to be adjusted the control of the lifting position of car 1.Wherein, exist from flatting method determination unit
In the case of 23 instruction for being set as other flat bed control methods, flat bed instruction department 24 is detected using the detection of position detector 8
The detection of the position (above-mentioned position h1, h2, h3, h4) of body 7, to be adjusted the control of the lifting position of car 1.
[example (example 1) of the hand-off process of 4. flat beds control]
Fig. 5 is to show the flow chart of the example (example 1) of the hand-off process of flat bed control that elevator control gear 20 is carried out.
First, elevator control gear 20 judges whether the car 1 in lifting carries out acting (step in the stopping that any layer stops
S11).It is standby until stopping action is in the case of at the time of not being to enter stopping action from lifting (step S11 is no)
Only.
When being judged as YES in step s 11 at the time of carrying out stopping action (step S11 is yes), elevator control gear 20 is sentenced
Whether disconnected position detector 8 detects the position h1 of the upper end of the detected body 7 of stop-layer or position h4 (Fig. 4) (steps of lower end
Rapid S12).Herein, in the case where not detecting position h1 or position h4 (step S12 is no), elevator control gear 20 is treated
Machine is until detecting position h1 or position h4.
When detecting position h1 or position h4 in step s 12 (step S12 is yes), elevator control gear 20, which obtains, to be examined
Count value (the step that the impulse generator 4 for being installed on governor 3 under at the time of measuring position h1 or position h4 is exported
S13).The count value is obtained by car position operational part 21.
Then, governor abnormality determination unit 22 judges comparable with the position of the car 1 accessed by car position operational part 21
Whether the count value of impulse generator 4 deviates the range (step S14) as the threshold value of predetermined benchmark.
Herein, in the case of being judged as in the range of the threshold value as benchmark in step S14 (step S14 is no),
Since speed regulator system is normal, switching instruction of the flatting method determination unit 23 without flat bed control operation.
On the other hand, (step S14 is in the case of being judged as in step S14 outside the range as the threshold value of benchmark
It is), flatting method determination unit 23 switches over flat bed instruction department 24 the flat bed control of the detection for position detector 8 is utilized
Instruction (step S15).In step S14 outside the range as the threshold value of benchmark in the case of, it is assumed for example that due to adjust
The performance of the damping mechanism 6 of fast device system is declined, and governor hawser 2 is caused to be in the state that abnormal vibrations have occurred.
Position of the flat bed instruction department 24 of switching instruction detected by based on position detector 8 is had received, to carry out flat bed control
System.
Then, elevator control gear 20 notifies the hydraulic performance decline of the damping mechanism 6 of speed regulator system to external central monitoring position
(step S16).
[example (example 2) of the hand-off process of 5. flat beds control]
Fig. 6 is to show the flow chart of the example (example 2) of the hand-off process of flat bed control that elevator control gear 20 is carried out.
In the flow chart of the Fig. 6, step S21, the processing in S22, S23 and the processing phase in step S11, S12, S13 of Fig. 5
Together, it omits the description.
Then, after the processing of step S23, elevator control gear 20 judges whether position detector 8 detects stopping
The position h2 of centre of detected body 7 of the layer or position h3 (Fig. 4) of lower end.Herein, position h2 or position are not being detected
In the case of h3 (step S24 is no), elevator control gear 20 is standby until detecting position h2 or position h3.
When position h2 or position h3 is detected in step S22 (step S24 is yes), elevator control gear 20, which obtains, to be examined
Count value (the step that the impulse generator 4 for being installed on governor 3 under at the time of measuring position h2 or position h3 is exported
S25).The count value is obtained by the car position operational part 21 of elevator control gear 20.
Then, governor abnormality determination unit 22 judges accessed count value in step S23, with being obtained in step s 25
The difference for the count value got, and judge whether the difference deviates the range (step as the threshold value of predetermined benchmark
S26)。
Herein, in the case of being judged as in the range of the threshold value as benchmark in step S26 (step S26 is no),
Since speed regulator system is normal, switching instruction of the flatting method determination unit 23 without flat bed control operation.
On the other hand, (step S26 is in the case of being judged as in step S26 outside the range as the threshold value of benchmark
It is), flatting method determination unit 23 switches over flat bed instruction department 24 the flat bed control of the detection for position detector 8 is utilized
Instruction (step S27).
The flat bed instruction department 24 for having received switching instruction carries out flat bed control based on the position detected by position detector 8
System.
Then, elevator control gear 20 notifies the hydraulic performance decline of the damping mechanism 6 of speed regulator system to external central monitoring position
(step S28).
[example (example 3) of the hand-off process of 6. flat beds control]
Fig. 7 be show to be installed on when car 1 in lifting stops speed that the impulse generator 13 of motor 12 detects, with
It is installed on the exemplary performance plot of speed that the impulse generator 4 of governor 3 detects.Then, based on the car shown in Fig. 7
The characteristic of speed during stopping, to illustrate to carry out the example (example 3) of the hand-off process of flat bed control.
First, with reference to Fig. 7, the characteristic of detected speed illustrates when stopping to the car 1 in lifting.Fig. 7
The longitudinal axis be speed, horizontal axis is the time.
Car 1 in lifting is installed on what the impulse generator 13 of motor 12 detected in the case where any layer stops
Speed V1 slowly declines, and until certain low velocity, and maintains the operating status under the certain speed of the low speed.So
Afterwards, under operating status of the elevator control gear 20 under the certain speed of low speed, the position for making car 1 is consistent with the floor that stops simultaneously
Stop.At this point, the speed V1 of car 1 becomes 0.
Herein, it is installed on the speed that the speed V2 that the impulse generator 4 of governor 3 detects is detected with impulse generator 13
Degree V1 has a little difference.That is, the speed V1 detected with the impulse generator 13 of 12 side of motor links, the arteries and veins of 3 side of governor
The speed V2 that generator 4 detects is rushed also to decline.Wherein, even if in the case where speed V1 becomes certain low velocity, speed
V2 is also carried out after slightly lower speed is dropped to for the time being, is slowly returned to the act of the certain low velocity identical with speed V1
It is dynamic.
The characteristic of speed V2 that the impulse generator 4 of 3 side of governor detects is that governor hawser 2 is non-vibrating normal
When characteristic, however in the case where abnormal vibrations have occurred in governor hawser 2, become the speed V3 of characteristic shown in Fig. 7.
That is, speed V2 when normal is shown compared with the speed V1 of 12 side of motor, after difference slowly expands, it is slowly returned to
The movement of speed V1.On the other hand, speed V3 when abnormal vibrations have occurred in governor hawser 2 is shown in governor hawser 2
It under the influence of exception, is changed within the shorter period, and returns to the movement of speed V1.Therefore, governor abnormality determination unit 22
The difference of speed V2 and speed V3 during stopping by detecting the car 1, so as to can determine that the exception of speed regulator system.Specifically
For, governor abnormality determination unit 22 in the count value of the impulse generator 13 for detecting 12 side of motor, with 3 side of governor
During difference state devious (state vibrated as shown in Figure 7) of the count value of impulse generator 4, speed governing can be judged
The exception of device system.
Fig. 8 is to show that applying the flat bed that the elevator control gear 20 for carrying out the principle judged extremely is carried out controls
The flow chart of the example (example 3) of hand-off process.
In the flow chart of the Fig. 8, the processing in step S31 is identical with the processing in the step S11 of Fig. 5, omits the description.
Then, when being judged as YES in step S31 at the time of carrying out stopping action (step S31 is yes), elevator controlling dress
The governor abnormality determination unit 22 for putting 20 starts to be installed on the acquisition (step of count value that the impulse generator 4 of governor 3 exports
S32).In addition, governor abnormality determination unit 22 starts to be installed on obtaining for the count value of the output of impulse generator 13 of motor 12
It takes (step S33).
Then, governor abnormality determination unit 22 judges the variation and pulse generation for the count value that impulse generator 4 is exported
The difference for the count value that device 13 is exported, and judge to whether there is deviation (step S34) in the difference.It is deposited in difference herein
In the state that the speed V3 that the state of deviation is equivalent in Fig. 7 is vibrated like that.
It is judged as that in difference speed regulator system is just there is no (step S34 is no) in the case of deviation in step S34
Often, switching instruction of the flatting method determination unit 23 without flat bed control operation.
On the other hand, in the case of being judged as in step S34 in difference there are deviation (step S34 is yes), flat bed
Method determination unit 23 switches over flat bed instruction department 24 instruction of the flat bed control of the detection for position detector 8 is utilized
(step S35).
The flat bed instruction department 24 for having received switching instruction carries out flat bed control based on the position detected by position detector 8
System.
Then, elevator control gear 20 notifies the hydraulic performance decline of the damping mechanism 6 of speed regulator system to external central monitoring position
(step S36).
[effect caused by 7. switching flat bed controls]
As discussed above, governor abnormality determination unit 22 switches elevator by judging the exception of speed regulator system
Control device 20 carries out control method during flat bed control, even if so as in the case where exception has occurred in speed regulator system,
It can carry out accurate flat bed control.
In addition, governor abnormality determination unit 22 judges that the abnormal state of speed regulator system is to inhibit the vibration of governor hawser 2
The structure member deterioration of damping mechanism 6, governor hawser 2 situations of abnormal vibrations has occurred, it is assumed that flat bed in this state
The precision deterioration of control.Therefore, it in this exemplary governor abnormality determination unit 22, is used by the way that flat bed control is switched to
The control method of position detected by position detector 8, so as to the deterioration of precision for preventing flat bed from controlling.
In addition, in the present case, can the abnormal judgement based on 6 grade speed regulator systems of damping mechanism, by speed governing
The exception of device system is notified to central monitoring position etc., therefore the replacement for the component that upkeep operation person can be sent promptly to be met
Deng processing.
[7. variation]
In addition, in above-mentioned embodiment example, the abnormal situation of speed regulator system is determined in governor abnormality determination unit 22
Under, as from it is usual when different other flat beds control, carried out the flat bed based on the position detected by position detector 8
Control, however other flat bed controls can also be switched to.For example, or be for example equipped on car 1 camera it is attached in door
It is closely shot, and the difference from the floor of the image recognition detection building side of the shooting image, with the floor of car 1, into
Row flat bed controls.
In addition, example 1, example 2 shown in flow chart in Fig. 5, Fig. 6, Fig. 8, in the processing of example 3, detected
Value as threshold value come outside the range that sets in the case of be determined as exception, and switch flat bed control, however as judgement
