Elevator control gear 31 and the slipping state judgement dress for judging the slipping state between driving rope sheave 4 and suspension body 10
Put 22 connections.Slipping state decision maker 22 is connected with slip detector 21.
Slip detector 21 is according to the signal from rotation detector 8 and the signal from position sensor 19, detection
Drive the amount of slip between rope sheave 4 and suspension body 10.
Specifically, slip detector 21 obtains according to the rotation amount of the driving rope sheave 4 detected by rotation detector 8

Office's property is skidded and locality is skidded.
Specifically, slipping state decision maker 22 detects the presence of following characteristic：That is, detected by rotation detector 8
In the case of a side in the speed that goes out and the driving force detected by traction machine motor 5 is increased, the opposing party is reduced.Also, beat
Sliding state determining apparatus 22 is according to floor gap amount of slip and whether there is above-mentioned characteristic, to judge being due to driving rope sheave 4 and suspension body
The decline of driving power between 10 and locally it is caused skidding and under normal traction state it is globally caused
Which side in small skidding.

In control.That is, elevator control gear 31 makes sedan-chair in the case where being determined as that skidding is exception caused by decline of driving power etc.
The operating in railway carriage or compartment 11 stops.
For example, elevator control gear 31 in the case where amount of slip reaches the 1st setting value, is judged to that there occurs larger to beat
It is sliding, make the emergent stopping of car 11.In addition, in the case that even amount of slip is not up to the 1st setting value, but set reaching than the 1st
The 2nd low setting value of definite value and there occurs locality skid in the case of, be also determined as driving power decline, make car 11 to most
Nearly floor or designated floor movement, and stop the operating of car 11.
In addition, elevator control gear 31, slip detector 21 and slipping state decision maker 22 pass through with only each other
Vertical microcomputer, realize mutually impregnable independent calculation process.
Here, the skidding detection process carried out by slip detector 21 is described in detail.First, in detection of skidding
The configuration space information for possessing tested drafting board 19a is needed in processing.
Fig. 3 shows the flow of the processing of the configuration space information for preserving tested drafting board 19a.In managing in this place, first
Car 11 is set to be moved to benchmark floor (being typically orlop) (step 1).Then, start car 11 until destination floor
Movement (step 2) untill (being typically the superiors).The signal from rotation detector 8 is added up in the movement, often
Aggregate-value is just preserved when by being detected drafting board 19a and is used as floor gap range information, and reset the processing (step of aggregate-value
3).Finally, terminate to handle when completing mobile untill destination floor.
The handling process is preferably carried out after lift appliance is just installed.That is, after lift appliance is just installed, shape is drawn
State is sound, does not produce skidding, it is thus possible to will drive the rotation amount of rope sheave 4 (caused by the rotation of the periphery of driving rope sheave 4
Advance amount) sendout of suspension body 10 is regarded as, it is capable of the floor gap aggregate-value of signal of spinning in future detector 8 as floor
Between distance handled.
In addition, what is illustrated below is judged as YES the feelings for the state do not skidded extremely by slipping state decision maker 22
Under condition, renewal can also be implemented and protect stored processing.
Below, skidding detection process is described in detail using Fig. 4.In managing in this place, as Fig. 3, make sedan-chair first
Railway carriage or compartment 11 is moved to benchmark floor (being typically orlop) (step 4).Then, start car 11 until destination floor (generally
The superiors) untill movement (step 5).The signal from rotation detector 8 is added up in the movement, whenever passing through
Just preserved during tested drafting board 19a aggregate-value as floor gap by when drive the rotation amount of rope sheave 4, and carry out replacement aggregate-value
Processing (step 6-1,2).
Also, using the rotation amount of driving rope sheave 4 preserved and the difference of floor gap range information as amount of slip export to
Slipping state decision maker 22 (step 6-3).Finally, terminate to handle when completing mobile untill destination floor.
Below, the determination processing of skidding state determining apparatus 22 is illustrated, Fig. 5~7 illustrate to be judged as skidding
Object multiple slipping states.The time of the amount of slip between driving rope sheave 4 and suspension body 10 is all shown in the drawings
Property change.
Fig. 5 shows in normal state globally caused less skidding, although how much size is due to car 11
Carrying state etc. and change, but larger skidding will not be produced in local time.On the other hand, Fig. 6 is shown in office
The larger skidding of caused locality under portion's abnormality, when the skidding develops by as continuation as shown in Figure 7 compared with
It is big to skid.
Here, when the relation between the amount of slip detected to slip detector 21 illustrates, in figure will beat
Dash area in sliding figure being accumulated by according to the time, each is equivalent to the amount of slip detected.Can according to these accompanying drawings
Know, in the case where producing the larger skidding of continuation, amount of slip differs widely with other two, easily makes a distinction.But
To globally producing the situation of less skidding in normal state and locally being produced under local anomaly state larger
Skidding in the case of, in the absence of the difference (or smaller) of amount of slip, both are cannot distinguish between according only to amount of slip.
On the other hand, Fig. 8 is the rotation for showing the driving rope sheave 4 when generating the smaller skidding of overall importance shown in Fig. 5
The curve map of the Temporal changes of the driving force of rotary speed and traction machine motor 5, Fig. 9 are to show generating the office shown in Fig. 6
The curve of the Temporal changes of the rotary speed of driving rope sheave 4 during the larger skidding of portion's property and the driving force of traction machine motor 5
Figure.
By using this rotary speed for driving rope sheave 4 and the transition information of the driving force of traction machine motor 5, Neng Goujin
The differentiation of the above-mentioned two states of row.Specifically, in the case where generating the skidding of locality, as shown in figure 9, producing
The phenomenon that the driving force of traction machine motor 5 declines while driving the rotary speed of rope sheave 4 to improve.
This is due to following situation and caused：Frictional force when producing skidding between suspension body 10 and driving rope sheave 4
Decline, by the driving force applied before frictional force will decline, rotary speed improves, and in common elevator, utilizes
Elevator control gear 31 is implemented to follow the control of command speed, thus by making speed reduce drive without departing from the control of command value
Power.
Therefore, the value that rotary speed is multiplied to obtain with driving force is focused on.Figure 10 is the rotary speed × driving for showing Fig. 8
The curve map of the Temporal changes of the value of power, Figure 11 are the Temporal changes of the value for the rotary speed × driving force for showing Fig. 9
Curve map.As shown in Figure 10, in the case where generating smaller skidding of overall importance, the value of rotary speed × driving force is normal
When mobility scale in constant.On the other hand, as shown in figure 11, in the case where generating the larger skidding of locality,
The value of rotary speed × driving force declines at the time of producing locality and skidding, mobility scale when deviate from normal.
So, by the way that rotary speed is multiplied with driving force, show significantly to deviate not producing the usual of locality skidding
The value of the mobility scale of traveling.Also, by catching the feature, it can more reliably make a distinction and detect exception.That is, it is logical
Cross and preset rotary speed the mobility scale of obtained amount when normal is multiplied with driving force, detect when floor gap is advanced
The situation of mobility scale when the product of rotary speed and driving force exceedes normal, can in high precision and simply detect locality
The generation of skidding.
Alternatively, it is also possible to not implement the computing that rotary speed is multiplied with driving force, and by individually judging to rotate respectively
Speed and driving force, to detect the generation of locality skidding.
Specifically, as shown in figure 12, setting and common driving force when floor gap is advanced first allows minimum
Deviation a1 and allow maximum deviation b1 with the rotary speed of usual traveling mode.Then, driving force deviation less than allowing
Minimum deflection a1 phenomenon and the deviation of rotary speed exceed allow maximum deviation b1 phenomenon it is simultaneous in the case of, judge
To be skidded for there occurs locality.
In addition, as shown in figure 13, also can be inclined according to the minimum of the usual driving force with car 11 when floor gap is advanced
Poor a2, what the rotary speed that setting to allow changed allows maximum deviation b2, exceedes in the maximum of rotary speed change
In the case of allowing maximum deviation b2, it is judged as generating locality skidding.
Here, the establishing method as b2, if so that with b2 with a2 reduce and increase and b2 as a2 increases and
The mode of the relation of reduction is set, then in the feelings for rising smaller but driving force and declining due to locality skidding of rotation amount
Under condition and in the case that decline is smaller but rotation amount rises because locality is skidded of driving force, can accurately it examine
Measure it is various in the case of locality skid.
For example, in the relation for making there is a2 and b2 to be inversely proportional, can according to multiplying according to rotary speed and driving force
Product benchmark equal when being judged is judged.As specific judgment mode, in fig. 12, the maximum deviation of rotary speed
More than benchmark b2, thus it can interpolate that skidded to generate locality herein.
Alternatively, it is also possible to this on the contrary, first determine speed maximum deviation, driving force is determined according to the maximum deviation
Allow minimum deflection, whether these feasible values are exceeded according to speed, to carry out producing the judgement of locality skidding.
Below, Figure 14 shows the flow of the specific slipping state determination processing of slipping state decision maker 22.Here,
During mobile beginning to destination floor, into slipping state determination processing.In slipping state determination processing, receive and come from
The information of the amount of slip of sliding detection means 21, the 1st datum quantity of the amount of slip received and amount of slip set in advance is carried out
Compare (step 7-1,7-2).
In the case where amount of slip is more than the 1st datum quantity, exports the 1st abnormality and return to waiting processing state (step
Rapid 7-3).On the other hand, amount of slip be less than the 1st datum quantity in the case of, into the amount of slip received with it is set in advance
2nd datum quantity (the 1st datum quantity of amount of slip>2nd datum quantity) comparison processing (step 7-4).
In the case where amount of slip is more than the 2nd datum quantity, also implementing slip properties has evaluation (step 7-5) without exception.
Specific evaluation method is as described above.
Be determined as slip properties deposit in an exceptional case, output the 2nd abnormality simultaneously return to waiting processing state
(step 7-6).On the other hand, in the case of being determined as that amount of slip is less than datum quantity in step 7-4 and in step 7-5
In be judged as that slip properties do not have exception in the case of, be directly entered waiting processing state.
Here, the meaning of the 1st abnormality and the 2nd abnormality is according to the 1st and the 2nd datum quantity as decision threshold
Set and change.For example, the 1st datum quantity be set to be produced under the traction state that can not safely carry out each floor stop in service
Raw amount of slip.Then, in the case where amount of slip is more than the 1st datum quantity, elevator control gear 31 makes car 11 rest in most
Nearly floor makes service stop immediately, therefore ensures that security.
In addition, the 2nd datum quantity is set to be the amount of slip according to the variation of load capacity etc. changed in normal state
Maximum.Then, it is below the 1st datum quantity and more than in the case of the 2nd datum quantity in amount of slip, the state of lift appliance is believed
Breath is delivered to outside.Thereby, it is possible to the utilization for the condition improvement for considering to involve early stage.
As the specific transfer device of transmission state information, such as it can contemplate and carried out using sound to car 11 is inside and outside
Broadcast, the electronic communication of the display that is carried out using image or lamp etc. in the car 11 and the portable phone to user.
Alternatively, it is also possible to by elevator control gear and maintenance activity person or the communication unit between repair company or
Portable phone etc., locality is skidded and increased communicated by information.In this case, by as must stop
Safeguarded before the state of lift appliance operating, lift appliance continuous running can be made, user will not be brought in operating
Only caused inconvenience.

[numerical expression 4]
In formula 4, by the tension force of the suspension body 10 of the side of car 11 and the power of the difference of the tension force of the suspension body 10 of the side of counterweight 12
(uneven weight) is set to L '+f (X).X represents the position of car 11, and L ' represents the portion suitable with the load capacity in car 11
Point.
In addition, f (X) represents the cable for being hung on the length of the suspension body 10 of driving rope sheave 4 and being hung by car 11
The length of class (power-supplying patch etc.), weight change part caused by car position change are set to depending on car position X's
Value.
Specifically, for example, if considering the tendency for bringing the weight of the cable of load proportionally to change with position,
A × X will be set to the item that car position proportionally changes, by the suspension for correcting the side of car 11 when car position X is 0
The power of difference of the tension force of the tension force of body 10 and the suspension body 10 of the side of counterweight 12 and the constant term for weighing apparatus of making even is set to B, can utilize all
