[characteristics of 3. load measuring sensors and vibration-proof rubber]
Fig. 3 is the output signal (voltage: the longitudinal axis) for indicating load measuring sensor 4 and load measuring sensor 4 at a distance from detection plate 5
The exemplary performance plot of the relationship of (mm: horizontal axis).Load measuring sensor 4 with and detection plate 5 at a distance from proportionally output voltage.If
By in carriage for without load when it is initial when load measuring sensor 4 at a distance from detection plate 5 (gap) be set as L1, then when this is initial
Distance L1 under load measuring sensor 4 output voltage be V1.If becoming payload ratings in carriage, vibration-proof rubber 3 is compressed,
Load measuring sensor 4 becomes the L2 shorter than L1 at a distance from detection plate 5, at this point, the output voltage of load measuring sensor 4 becomes V2.
Here, it may occur that vibration-proof rubber 3 is because of initial contraction and lasts deterioration to also not recover under no loading condition
The case where position of distance L1 when initial.For example, the load measuring sensor 4 when being without loading in carriage is at a distance from detection plate 5
Become the L11 shorter than distance L1.
Fig. 4 is the relationship for indicating to detect the load (useful load) in load detecting portion 22 based on the output signal of load measuring sensor 4
Performance plot.In Fig. 4, the longitudinal axis indicates useful load (%), and horizontal axis indicates the output voltage (V) of load measuring sensor 4.It is shown in Fig. 4
The value of useful load detected by load detecting portion 22 is recorded in load setpoint record portion 25.Load detecting portion 22 is by nothing
The output voltage V1 of load measuring sensor 4 is set as useful load 0% in carriage when loading, by when nominal load load measuring sensor 4 it is defeated
Voltage V2 is set as useful load 100% in carriage out.Load setpoint record portion is recorded to from the value of the 0% increased useful load
In 25.
Utilize the output voltage of the load measuring sensor 4 shown in Fig. 4 and the linear relationship of useful load, load compensation torque meter
Calculation portion 24 calculates the torque needed in advance when elevator starting, and using the calculated torque as inverse before opening braking (not shown)
Torque instruction needed for becoming device device 26 is sent.
However, if as shown in the L11 of Fig. 3, no load measuring sensor 4 when loading is at a distance from detection plate 5 because of vibration-proof rubber 3
Initial contraction and shorten, even if the output voltage of load measuring sensor 4 also becomes V11, thus such as then in carriage in no loading
Shown in Fig. 4, it is judged as the useful load in carriage with K%.Therefore, the torque if initial contraction amount becomes larger, when elevator starts
It is no longer appropriate, the seating of elevator can be felt to impact.
Load measuring sensor output valve when Fig. 5 and Fig. 6 show non-loaded in carriage lasts variable quantity.In Fig. 5 and Fig. 6,
The longitudinal axis indicates the displacement L in the gap of load measuring sensor 4x, what horizontal axis expression setting elevator rose passes through number of days.Here displacement
LxIt is indicated with L11-L1 (referring to Fig. 3).Fig. 5 is the example of the bigger elevator of the temperature change in elevator, and Fig. 6 is elevator
The example of the smaller elevator of interior temperature change.For example, can be upper with outside air temperature for the temperature being arranged in elevator
The case where rising the elevator in such environment in linkage is risen, as shown in figure 5, the temperature change become in elevator is bigger
State.On the other hand, in the case where having air-conditioning work in 24 hours in the facility for being provided with elevator, as shown in fig. 6, becoming elevator
The smaller state of temperature change in well.
After by elevator setting into facility, vibration-proof rubber 3 generates initial contraction amount Δ Ls.In addition, vibration-proof rubber 3 is because of season
It saves and stretches repeatedly, the variable quantity in the whole year is Δ Lse.The variation delta Lse in the whole year is as shown in figure 5, be 1 year intrinsic displacement Δ Lx
Minimum value Δ Lmin 1 and displacement LxMaximum value Δ Lmax 1 difference.While with variation delta Lse between this year,
Displacement LxIt is become larger because of the deterioration of vibration-proof rubber 3.
By comparing Fig. 5 and Fig. 6 it is found that initial contraction amount the Δ Ls and variation delta Lse caused by season of vibration-proof rubber 3
It is different according to the setting environment of elevator.Therefore, it carries out resetting using the load setpoint record portion 25 of actual loading
Plan be not maintenance plan that indifference determines, and the contraction for allowing for the initial contraction amount of vibration-proof rubber 3, lasting
It measures and is generated because stretching caused by season.
[determination processing of the initial contraction of 4. vibration-proof rubbers]
Fig. 7 is the determination processing example for indicating the vibration-proof rubber initial contraction implemented by the diagnostics division 43 of maintenance plan generating means 40
Flow chart.Firstly, diagnostics division 43 reaches most in step S401 from the load measuring sensor gap that database 42 extracts every day
Small value (step S401).Here load measuring sensor gap is the gap detected when without loading by load measuring sensor 4.So
Afterwards, diagnostics division 43 determines whether the specified time limit (being here 6 months) after initial setting receives in load setpoint record portion 25
Collect data (step
S402).Here, during the prescribed period (step S402 is no) in the case where the interior data without collection, diagnostics division 43 is transferred to
The processing of step S401, back to the extraction process in load measuring sensor gap.
In addition, existing in the case where collection data (step S402 is yes) in during the prescribed period, 43 computational rules of diagnostics division
The slope K s (step S403) of period (being here every 10 days) interior load measuring sensor spacing variable quantity.Then, diagnostics division 43 judges
The slope K s of calculating whether >=0 Ks (step S404).Ks >=0 indicates that state of the slope K s equal to 0 or slope K s are greater than
0 state.Here, when being judged as is not Ks >=0, i.e. when slope K s is less than 0 value (step S404 is no), in load
The state that weight sensor gap persistently shortens, diagnostics division 43 is determined as that vibration-proof rubber 3 continues initial contraction, and is transferred to step
S403。
Also, when being judged as that slope K s is Ks >=0 (step S404 is yes), diagnostics division 43 determines vibration-proof rubber 3
Characteristic is that the elongation under thermal expansion caused by season (temperature) causes load measuring sensor gap to become more than initial contraction
Change, and is transferred to step S405.That is, it is Ks that diagnostics division 43, which changes the slope K s of load measuring sensor gap variable quantity from Ks < 0,
The maximum value of the variable quantity in load measuring sensor gap when >=0 | Δ Ls | and measure maximum value date recorded (step
Rapid S405).
Later, whether the state that diagnostics division 43 determines that slope K s is positive has continued to exceed the stipulated number that can arbitrarily set
(step S406) returns to the processing of step S403 if condition is invalid (step S406 is no).Also, the condition at
In the case where vertical (step S406 is yes), diagnostics division 43 establishes vibration-proof rubber initial contraction complement mark (step S407).Then,
Whether diagnostics division 43 determines the absolute value (| Δ Ls |) of the initial contraction amount Δ Ls of vibration-proof rubber 3 greater than arbitrary threshold value Δ th's
Absolute value (| Δ th |) (step S408).Here, arbitrary threshold value Δ th be set as load load-carrying variable quantity can be to the loading of elevator
The value that the detection of load-carrying impacts.
Diagnostics division 43 is in step S408 | Δ Ls | > | Δ th | condition set up when (step S408 is yes), establish operation
Plan Warning Mark, and is sent to maintenance plan generating means 40 (step S410).On the other hand, in step S408 | Δ Ls |
> | Δ th | condition it is invalid when (step S408 is no), diagnostics division 43 is transferred to vibration-proof rubber 3 by the judgement of seasonal effect
It handles (step S409).
[determination processing of 5. vibration-proof rubbers by seasonal effect]
Fig. 8 is the judgement of the vibration-proof rubber 3 that indicates to be implemented by the diagnostics division 43 of maintenance plan generating means 40 by seasonal effect
Manage the flow chart of example.Firstly, diagnostics division 43 determines whether to establish the initial contraction complement mark (step of vibration-proof rubber 3
S501).Here, in the case where not setting up initial contraction complement mark (step S501 is no), diagnostics division 43 carries out standby, directly
To establishing initial contraction complement mark.(step S501 is yes), diagnostics division in the case where establishing initial contraction complement mark
43 establish seasonal move mark Fh=1, and are initially set (step S502).
Also, the slope K s of (being here every 10 days) interior load measuring sensor gap variable quantity during 43 computational rules of diagnostics division
(step S503).Later, diagnostics division 43 determines whether to establish seasonal move mark Fh=1 (step S504).Here, it is establishing
In the case where seasonal move mark Fh=1 (step S504 is yes), the slope K s that is calculated in diagnostics division 43 judgment step S503
Whether Ks < 0 (step S505).By this judge to be judged as slope K s not be 0 < Ks in the case where (step S505 is no),
It is determined as that the elongation quantitative change under the thermal expansion that vibration-proof rubber 3 is generated by season (temperature) is more, the shape that load measuring sensor gap becomes larger
State continues, and the processing of return step S503.
In the case where being judged as that slope K s is Ks < 0 in step S505 (step S505 is yes), diagnostics division 43 is to from Ks
Minimum value Δ Lmin1, elevator well temperature and the measurement day of load measuring sensor gap variable quantity when >=0 becomes Ks < 0
Recorded (step S506).Processing in step S506 is in the elongation being judged as under the thermal expansion generated by season (temperature)
Execution when amount becomes smaller, will not further be affected by temperature.Later, whether the state that the judgement of diagnostics division 43 Ks becomes Ks < 0 connects
Continuous has been more than the stipulated number (step S507) that can arbitrarily set.Here, it if the condition is invalid (step S507 is no), examines
Disconnected portion 43 returns to the processing of step S503.In the case where the condition of step S507 is set up (step S507 is yes), diagnostics division
43 are equipped with seasonal move mark Fh=0, and return to the processing of step S503.
In addition, in the judgement of step S504 in the case where seasonal move mark Fh=0 (step S504 is no), diagnosis
Portion 43 judges whether slope K s is >=0 Ks (step S509).In the judgement, (i.e. Ks the case where slope K s is not Ks >=0
The case where 0 <) under (step S509 is no), diagnostics division 43 return to step S503 processing.Sentence in the judgement of step S509
Breaking as slope K s is (step S509 is yes) in the case where >=0 Ks, to load measuring sensor when becoming Ks >=0 from Ks < 0
The maximum value of gap variable quantity | Δ Lmax1 |, elevator well temperature and measurement day recorded (step S510).The step
Processing in S510 is being judged as because the elongation quantitative change under the thermal expansion of season (temperature) generation is more, sensor gap becomes larger again
Shi Zhihang.
After recording in step S510, whether the state that the judgement of diagnostics division 43 Ks becomes >=0 Ks has continued to exceed and can appoint
The stipulated number (step S511) of meaning setting.(step in the case where being judged to not continuing to exceed stipulated number in the judgement
S511 is no), diagnostics division 43 returns to the processing of step S503.Also, it is judged to continuing to exceed in the judgement of step S511
In the case where stipulated number (step S511 is yes), diagnostics division 43 is to seasonal move amplitude, ao Lse=| Δ Lmax1 |-| Δ
Lmin1 | recorded (step S512).Later, seasonal move amplitude, ao Lse is scaled by diagnostics division 43 loads load-carrying variation width
Degree, and calculated in carriage by temperature change without the amplitude of fluctuation (step S513) for loading load-carrying under loading condition.Here
Conversion carried out based on Fig. 3 and characteristic shown in Fig. 4.
After being scaled loading load-carrying amplitude of variation, the loading load-carrying conversed in 43 determination step S513 of diagnostics division changes
Whether amplitude is more than the threshold value that can arbitrarily set of burden rating (step S514).Here, in the case where more than threshold value
(step S514 is yes), diagnostics division 43 is measuring maximum value | Δ Lmax1 | and minimum value | Δ Lmin1 | month at record
In intermediate month (intermediate month), and establish the big mark (step S515) of seasonal move amplitude.
Also, after establishing the big mark of seasonal move amplitude in step S515, it is judged as in step S514 and does not exist
In the case where more than threshold value (step S514 is no), diagnostics division 43 determines the variable quantity in load measuring sensor gap | Δ Lmax1 | be
It is no to be greater than threshold value | Δ th |.Here, in the variable quantity in load measuring sensor gap | Δ Lmax1 | it is greater than threshold value | Δ th | in the case where
(step S516 is yes), diagnostics division 43 establishes production plan Warning Mark, and sends operation meter to maintenance plan generating means 40
It draws Warning Mark (step S517).On the other hand, in the variable quantity in load measuring sensor gap | Δ Lmax1 | it is less than threshold value | Δ th |
In the case where (step S516 is no), diagnostics division 43 return to step S501 judgement (step S518), continue monitor vibrationproof rubber
It the shrinkage of glue and is influenced caused by season (temperature).
[the generation processing of 6. operations instruction plan]

It is), operation instruction planning department 44 determines whether to be provided with the elevator (step S606) of identical machine parallel.Also, it is setting parallel
In the case where being equipped with the elevator of identical machine (step S606 is yes), the elevator of identical machine is sentenced by operation instruction planning department 44
It is whether identical (step S607) to determine the upkeep operation moon.In addition, making in the case where the upkeep operation moon is identical (step S607 is yes)
Industry instruction planning department 44 determines that temperature change whether is set within whole year is specified the moon (step S608) in intermediate plan.It should
Judgement in step S608 is the flexible processing for being affected by temperature biggish scene and being determined in vibration-proof rubber 3.
Also, it is determined as (step when set temperature variation specifies the moon in intermediate plan in the judgement of step S608
Rapid S608 be yes), operation instruction planning department 44 is adjusted production plan to the elevator, so that from planning the specified moon recently
The adjustment operation (step S610) using actual loading is carried out in the upkeep operation moon.At this point, operation instruction planning department 44 is judged as
It is similarly deteriorated in the same machine other than production plan indicating elevator and parallel arrangement of elevator, thus simultaneously
Production plan is carried out, to can be reduced the scheduling job being adjusted using actual loading.
In addition, being determined as (step when non-set temperature variation specifies the moon in intermediate plan in the judgement of step S608
Rapid S608 be no), influenced as caused by the temperature of vibration-proof rubber smaller, operation indicates the progress of planning department 44 next
Check that the middle of the month uses the adjustment production plan (step S611) of actual loading.At this point, it is also same as the processing in step S610, it is right
Other parallel arrangement of elevators also carry out production plan.
In addition, be determined as in step s 605 it is not set in the case where sentence in (step S608 is no) or step S609
It is set in not parallel arrangement of situation the situation for being determined as that the upkeep operation moon is different in (step S609 is no) or step S610
Under (step S610 is no), be transferred to the determination processing of step S609.In step S609, operation instruction planning department 44 determines whether
It is set with the plan based on seasonal move and specifies the moon.Here, in the case where being judged to having the specified moon (step S609 is yes), make
Industry instruction planning department 44 is only adjusted production plan to production plan indicating elevator, so that in the dimension nearest from the plan instruction moon
The adjustment operation (step S612) using actual loading is carried out in the shield operation moon.On the other hand, it is determined as not having in step S609
In the case where having the specified moon (step S609 is no), operation instruction planning department 44 is only adjusted work to production plan indicating elevator
Industry plan, so that carrying out the adjustment production plan (step S613) using actual loading in the upkeep operation moon next time.
In the above process, by the variation to every elevator monitoring load measuring sensor gap, thus to vibration-proof rubber
Initial contraction and shrink caused by lasting and temperature caused by influence to be monitored, and be changed to defined threshold from initial value
When value, the adjustment using actual loading is carried out by indicating, so as to indicate to carry out operation with the appropriate period.In addition, passing through
Production plan also is carried out simultaneously in parallel elevator, so as to once be made simultaneously by multiple elevators in a facility
Industry can be reduced the number that actual loading is carried to correct operation, so as to efficiently be modified operation.
[7. variation]
In addition, when establishing production plan, the intermediate month in the month there are seasonal move establishes in above embodiment
Carry out the plan of operation.Determine in this way as unit of the moon and the plan of establishing is an example, also can use week, date etc.
Other information judges not by the period of seasonal effect, and establishes production plan.For example, operation instruction planning department 44 also can be determined that
It detects the intermediate date of that day and that day for detecting seasonal move minimum value of seasonal move maximum value, and establishes
The operation that the intermediate date nearby carries out operation indicates plan.Alternatively, can also be judged appropriate as unit of week age
Week, to establish the operation instruction plan for carrying out operation.By by day, week as unit of establish plan, so as to establish plan, with
More suitable period carries out operation.
In addition, when being modified operation, temperature that temperature detector 11 detects can be used also as to temperature
The correction amount that caused variable quantity is corrected.That is, can also be carried out since vibration-proof rubber 3 can stretch because of temperature
The more accurate amendment that the temperature variation is taken into account.In addition, the setting of temperature detector 11 is supplying in above embodiment
In the elevator that elevator 1 is advanced.It is preferred that temperature detector 11 is arranged in elevator like this, but as long as being at least provided with
Thermometer is set in the facility of elevator.In addition it is also possible to the record of the temperature as detected by temperature detector 11 is omitted,
To without amendment based on temperature.
In addition, in the flowchart of fig. 9, being provided with the elevator of same machine and the upkeep operation moon parallel in same facility
In identical situation, production plan is established, to carry out operation to the elevator of parallel arrangement of same machine simultaneously.In contrast,
It can also also be judged as there are non-parallel setting but in the case where the elevator of the different location in same facility is arranged in
It is higher that it is in a possibility that same state, so that production plan is established, to carry out operation simultaneously.Even in this case, example
The elevator of the same machine of different places in same facility is such as set, can also only be detected in respective temperature detector 11
In the case that the temperature arrived is the temperature of similar trend, establishes production plan and come while carrying out operation.
