Abstract
An elevator equipment does controlled running to the elevator when the hurricane or strong wind takes place, according to the signal detected by the vibration detector (5) which is arranged on the top of the hoist trunk (20) or the top of building, it forecasts and calculates the vibration and responding of the main suspension cable (7) and the like long dimension component in the hoist trunk (20), and sends out controlling dictation according to the computed result. The elevator equipment of the present invention can detect the vibration of the main suspension cable with high precision when the earthquake or strong wind takes place and do controlled running.
Description
Technical field
The present invention relates to a kind of lift facility, this lift facility carries out the control operation when causing building to rock because of earthquake or high wind.
Background technology
When earthquake took place, P ripple (compressional wave) and propagation speed be slowly but the S (shear wave) that presents the earthquake main motion propagates into building from focus respectively faster for propagation speed.As prior art, for example disclose a kind of scheme in following non-patent literature 1: the acceleration levels of building being rocked the horizontal direction of the detected S ripple of device is categorized into by special inferior grade, inferior grade and the high-grade threshold levels that constitutes, and control operation when carrying out the earthquake of elevator with this.Before the building that the main motion because of the S ripple produces rocks change greatly, special low-grade acceleration/accel by the detection level direction, perhaps by carrying out in the bottom of building and can detecting the P ripple initial stage fine motion detection that earthquake arrives in Zao several seconds than S ripple, elevator is suspended, carry out the control operation with this.
In addition, be subjected to the influence of focus earthquake far away, the long period earthquake takes place easily at the region of no relief with accumulation horizon, when the long period earthquake takes place or during high wind, though building to rock acceleration/accel little, but, the top of building rocks because can producing, so the main hoist cable of elevator, speed controller rope and (following these parts are referred to as " the long yardstick parts ") such as cables used to the cable and the signal communication of lift car power supply are easy to generate and rock, thereby contact with other equipment generations, cause device damage.Below, abbreviate rocking of this kind building as " building rocks ", building rocked the long yardstick parts that cause rock and vibrations are called " long yardstick parts rock ", and when these degree of rocking of expression, represent with " building rolling momentum " and " long yardstick parts rolling momentum ".
The acceleration levels that building during the long period earthquake rocks is low, if improve the acceleration detection sensitivity that building rocks in order to detect the low acceleration/accel of this grade, thereby then elevator may carry out unnecessary control and moves because of directly causing noise vibrations beyond the reason that long yardstick parts rock produce misoperation.Therefore, in order to reduce this kind misoperation, for example disclose a kind of control operating method in the prior art shown in patent documentation 1 and the patent documentation 2, its quantity of state by the speed, displacement or the speed that detect the building that is close with long yardstick parts vibrating state amount as far as possible and rock and the product of displacement etc. carries out control and moves.
Patent documentation 1: the patent of invention spy of Japan open clear 60-15382 communique ( claim 1 and 2, Fig. 2)
Patent documentation 2: the patent of invention spy of Japan open clear 60-197576 communique (claim 1, Fig. 8)
Non-patent literature 1: 94～100 pages of second one of version in 2002 " explanation of elevator technology standard " that Ministry of Land, Infrastructure and Transport dwelling house office building guidance class, Foundation's Japanese architecture equipment and elevator center and Corporation Japan elevator association edit.
As implied above, in described prior art, though the quantity of state of the acceleration/accel of building and the product of speed, displacement or speed and displacement etc. has carried out the control operation during by the detection earthquake, these prior aries are not carried out the control operation according to the quantity of state that directly causes long yardstick parts to rock.
And, make skyscraper produce the long period earthquake of rocking easily, it is a kind of earthquake that in the process that the remote earthquake in focus ground is propagated in the Plain part that is made of accumulation horizon in Plain, the similar Northeast etc., takes place, because the general apart from each other of its focus, reach 150～200 kilometers, so the P ripple is very faint.
Its result, exist P ripple initial stage fine motion control can't bring into play its function, when elevator travels, long yardstick parts can come in contact with the equipment in the hoist trunk and produce problems such as passive safety, if take place and when improving the P wave detection sensitivity, then exist the elevator can be because of in-plant small-scale earthquake or the problem that enters meaningless suspended state with the irrelevant noise vibrations of earthquake for fear of this kind situation.And, the speed of rocking according to building, when the quantity of state of the product of displacement or speed and displacement etc. is judged rocking of long yardstick parts indirectly, owing to can't understand state variation such as increase degree that long yardstick parts rock and degree of damping one by one, does so also there is the problem that can not make correct judgement to following situation: (1) allow that reducing command speed runs slowly? (2) make elevator temporarily enter suspended state? (3) whether can make the elevator operation of taking refuge, rocking the position that can not increase significantly and make elevator move to long yardstick parts, can promptly long yardstick parts do not rock or not the position that produces resonance with building? perhaps (4) degree of damping that can't rock according to long yardstick parts etc. is reasonably determined the control operation releasing time of elevator etc.
For example, because of the building in the long period seismic motion rocks increase degree that the long yardstick parts that cause rock and degree of damping etc. to a great extent by the rolling flowing mode of building with rock lasting degree decision, so, the speed that only relies on building to rock, the quantity of state of the product of displacement or speed and displacement etc., then can't judge increase degree and degree of damping that long yardstick parts rock, so taked following control operation, promptly when judging that rocking has appearred in long yardstick parts, estimating that long yardstick parts rock greatly stopped in 3～5 minutes, and made the elevator stagnation of movement in this time period.
Summary of the invention
The object of the present invention is to provide a kind of high lift facility of control running precision that can address the above problem.
To achieve these goals, lift facility of the present invention carries out the control operation to elevator when earthquake or high wind take place, it is according to the detected signal of vibrations instrument that is arranged on hoist trunk top or building top, calculate the rolling momentum of long yardstick parts according to the rolling momentum of building, and according to this result of calculation, the control of rocking of long yardstick parts moves.
And, move by the control of rocking of carrying out described long yardstick parts, avoid elevator under the state that long yardstick parts rock, to travel, thereby can avoid making the passenger produce uneasiness, when avoiding elevator to travel with hoist trunk in equipment produce and to contact and produce passive safety, simultaneously, when also having adopted earthquake and the elevator control operation scheme during high wind, the building when this control operation scheme is used in combination the corresponding elevator earthquake of acceleration levels that of the prior art and building rock rocks the control operation scheme and described long yardstick parts rock the control operation scheme.
According to the present invention, can provide a kind of when detecting earthquake accurately and the long yardstick parts during high wind rock, thereby the elevator that carries out the control operation.

The specific embodiment
Followingly embodiments of the invention are described with reference to accompanying drawing.
Fig. 1 is the structural representation of the elevator in the embodiment of the invention.The lift facility of present embodiment is configured to, and lift car 1 is along not shown lifting rail, and counterbalanced weight 2 is also along not shown lifting rail.And lift car 1 and counterbalanced weight 2 are hung as bucket type by the main hoist cable 7 by the winch 4 in the Machine Room 21 on hoist trunk 20 tops, and are driven by winch 4.At this, be provided with control panel 3 and governor 6 and vibration detector 5 in the Machine Room 21, rope 8 is wound on the governor 6.And, from winch one side, being provided with balance hoist cable 9, this balance hoist cable 9 is used for the weight difference between the main hoist cable 7 of compensating elevator car 1 side and counterbalanced weight 2 sides.In addition, also be provided with the stern fast 10 of powering to lift car 1.So, be provided with main hoist cable 7, speed controller rope 8, balance hoist cable 9 and stern fast 10 isometric yardstick parts in hoist trunk 20.In addition, also be provided with the support 22 of equipment etc. in the hoist trunk that is used for supporting guide and elevator in the hoist trunk.
Be used to detect the vibration detector 5 that building rocks, except function, also have the function of the acceleration/accel that detects the z direction with the acceleration/accel that detects mutually orthogonal horizontal direction (x, y direction).Wherein, the acceleration/accel of z direction be used to judge the initial stage fine motion when seismic motion arrives and judge building rock by seimic still be to cause by high wind.At this, the acceleration pick-up of vibration detector 5 is formed by x, y direction one two and the sensor combinations of z axis of orientation, perhaps the 3-axis acceleration sensor by x, y, z direction one constitutes, and perhaps forms by making up each axial acceleration pick-up respectively.And, has arithmetic section 30 in the storage case of vibration detector 5, described arithmetic section 30 has control operation arbitration functions, it calculates the rolling momentum of long yardstick parts according to the acceleration signal of vibration detector 5 detected x, y direction, the rolling momentum and the pre-set threshold of long yardstick parts are compared, and in control panel 3, judge whether to carry out elevator control operation.At this, arithmetic section 30 also can be accommodated in the control panel 3 as the case may be.
And this arithmetic section 30 also has the function that the building that carries out as prior art rocks the control operation, and the horizontal direction acceleration/accel that its caused building of S ripple according to by earthquake the time rocks carries out building and rocks the control operation.
And, can pass through the vertical tremor measuring ability of vibration detector 5, though occurred rocking at long yardstick parts, when not detecting the vibrations of above-below direction, judge that rocking by high wind of these long yardstick parts causes, and with this control advisory passenger.
The calculation process of carrying out in described arithmetic section 30 based on the stability of handling and easily reasons such as preset parameters changes are set at digital processing, but also can be arranged to analog processing with it.
Fig. 2 is the structure instruction diagram of arithmetic section 30.The detection signal that arithmetic section 30 has the x, the y that are used for from vibration detector 5, a z direction is removed high-pass filter 31 (the x direction: 31X of the dc shift component that gravitational acceleration component that the levelness installation error because of vibration detector 5 causes and acceleration pick-up body had, y direction: 31Y, z direction: 31Z) and low-pass filter 32 (the x direction: 32X that is used for removing denoising vibrations component, y direction: 32Y, z direction: 32Z).And, when not needing P ripple by seismic motion to arrive in early days to judge, perhaps do not need to judge building rock by seimic or by high wind cause the time, there is no need to be provided with acceleration pick-up and filter 31Z, the 32Z of z direction.
In addition, arithmetic section 30 also has and rocks compose operation part 37,38,39 and rock judgment part 40 according to what the rolling momentum of these compose operations judged whether that long yardstick parts rock the control operation, and the signal that rocks judgment part 40 is sent to control panel 3 by signal wire (SW) 41.Wherein, the above-mentioned compose operation that rocks partly constitutes x direction rolling dynamic response arithmetic section 34X, 35X, 36X and Y direction rolling dynamic response arithmetic section 34Y, 35Y, 36Y, and synthetic each long yardstick parts rock the x of natural period, the rolling dynamic response operation result of y direction, x direction rolling dynamic response arithmetic section 34X, 35X, 36X and Y direction rolling dynamic response arithmetic section 34Y, 35Y, 36Y uses the output signal 33X of filter 32X and the output signal 33Y of filter 32Y, at by predefined natural period Ta, Tb, each long yardstick parts that a plurality of long yardstick parts that Tc constitutes rock in the vibrating mode rock vibrating mode, and the rolling momentum of the long yardstick parts of each time point is calculated.
In rocking judgment part 40, threshold value is arranged to a plurality of stages, and according to its grade, judge the restriction of running velocity, the time-out of operation, the recovery after maintainer's safety inspection, perhaps judge the Reduction Level that long yardstick parts rock, can remove the elevator control operation of carrying out at rocking of long yardstick parts thus.
Use the output signal 33X of filter 32X and the output signal 33Y of filter 32Y in the horizontal direction in the acceleration/accel compose operation part 42, building on the horizontal direction that causes of the S ripple of calculating during by earthquake rocks acceleration/accel, and rock in the judgment part 43 according to this result of calculation at building and to judge whether to carry out the control operation that building rocks, simultaneously this signal is sent to control panel 3 by signal wire (SW) 44.Rock among the embodiment of judgment part 43 at building, it is method according to non-patent literature 1, rock acceleration/accel according to building and judge what building rocked, but also can be shown in patent documentation 1 and patent documentation 2 like that, make building rock judgment part 43 and have the function that the speed of rocking according to building or displaced condition amount are judged.
In the acceleration detection of above-below direction, also adopt following method, promptly, according to the high-pass filter 31Z by being used to remove gravitational acceleration component be used for removing signal behind the low-pass filter 32Z of denoising vibrations component, P ripple initial stage fine motion when in up-and-down movement arithmetic section 45, detecting earthquake, and this signal is sent into building rock in the judgment part 43.
P ripple initial stage fine motion during earthquake detects, in general, P ripple detector 24 in the elevator hole 23 that is arranged on hoist trunk 20 shown in Figure 1 carries out, but because up-and-down movement can increase in building, so, the Z directional acceleration sensor of the vibration detector 5 by being arranged on building top detects the initial stage fine motion, compares with the occasion that detects in elevator hole 23, can further improve accuracy of detection.And, can also alleviate the misoperation that easy detected transportation noise vibrations are produced in the part of elevator hole.
The signal that rocks judgment part 43 according to building shown in Figure 2 judge building to rock control and the prior art shown in the non-patent literature 1 that acceleration/accel carries out basic identical, but in non-patent literature 1, owing to can not be directly carry out control according to the rolling momentum of long yardstick parts, so when the setting building rocks the acceleration rate threshold of judgment part 43, not that acceleration levels allowed on the structural strength according to elevator is set, but along with depth of building raises, dwindle the setting value of acceleration rate threshold gradually, relax degree of damage with this.And in the present embodiment, owing to can rock control by rocking judgment part 40 long yardstick parts, so when the setting building rocks the acceleration rate threshold of judgment part 43, can set high acceleration rate threshold, be about to it and set the threshold value (about 100～150Gal) that the allowable strength with the structure of elevator and mechanism adapts for, thus, can avoid when the few in-plant small-scale earthquake of long period component takes place, carrying out unnecessary acceleration/accel control.
The treatment scheme of computing is rocked in explanation according to the long yardstick parts of output signal 33X, the 33Y of the filter in the arithmetic section 30 32 in Fig. 3.
34X represents to use output signal 33X, the 33Y of filter 32, calculate the arithmetic section of x directional response with natural period Ta, 34Y represents y directional response arithmetic section, 35X represents to calculate with natural period Tb the arithmetic section of x directional response, 35Y represents y directional response arithmetic section, 36X represents to calculate with natural period Tc the arithmetic section of x directional response, and 36Y represents y directional response arithmetic section.37,38,39 expressions are rocked the compose operation part to what rocking of the x of each described natural period, y direction synthesized, and have represented computing signal waveform example at each position.
Be example with main hoist cable 7 in Fig. 4, the three dimensional pattern figure when adopting long yardstick parts to rock describes calculation function and the control operation arbitration functions that arithmetic section 30 has concurrently.
Vibrating locus on 51 two-dimensional surfaces that are illustrated in the bigger roughly horizontal plane on midway location 50 of the amplitude of the main hoist cable 7 that rocks with three dimensional constitution, 34X, 35X, 36X represent the projection components towards X-axis of the vibrating locus 51 of each natural period Ta, Tb, Tc is carried out the x direction rolling dynamic response arithmetic section of the long yardstick parts of computing, and 34Y, 35Y, 36Y represent the y direction rolling dynamic response arithmetic section to the long yardstick parts that carry out computing towards the projection components of Y-axis.Thus, rock the x that carries out in the compose operation part 37,38,39 in the horizontal plane 50, the compose operation of y direction component what the long yardstick parts in each cycle rocked.
Following casehistory rocks the control of rocking of computing based on the long yardstick parts of present embodiment.(α＜β＜γ＜δ) as the threshold value of rocking judgment part 40, the embodiment that rocks control with the rolling momentum according to long yardstick parts describes for ratio α %, the β %, γ % and the δ % that rock limit size L that come in contact at support 22 grades with respect to main hoist cable 7 with the rolling momentum of long yardstick parts shown in Figure 4.
It is in service to rock control at long yardstick parts, make and rock judgment part 40 and have control operation arbitration functions, promptly carry out the control operation of following mode: when the rate of rocking of long yardstick parts surpasses β %, run slowly or the operation of the forced call control when top (under the state of main sling shaking, if it is top that lift car directly drives to, then lift car produces unusual vibrations sometimes, so one deck produces virtual call by operating software before top, make the interim operational mode of stopping of elevator) etc. the operation controlled operation that travels, when surpassing γ %, operation suspension when decaying to β % when following, restarts the controlled operation that travels, when decaying to α % when following, the operation of decontroling, when surpassing δ %, the maintenance in hoist trunk makes elevator out of service before finishing.
The effect that below the elevator control of explanation when earthquake is in service when being used in combination the long yardstick parts shown in the present embodiment and rocking control and building used in the prior art and rock control.Long yardstick parts rock control and building rocks control by being used in combination, the P ripple initial stage that employing is carried out according to predefined P ripple threshold value and S ripple threshold value is detected control and the monitoring control of S ripple initial stage, even missed the faint P ripple initial stage fine motion in the long period seismic motion, also can detect long yardstick parts and rock control by the initial stage of S ripple.Specifically, long yardstick parts rock after the S ripple arrives, its intensity roughly increased in 30～60 seconds, so long yardstick parts of stage rock control in early days, can make elevator move to the position that long yardstick parts are difficult to rock as the case may be and take refuge.At this, after adopting S ripple initial stage control, because of the situation of small-scale earthquake in the temporary transient stop of floor recently can increase to some extent, but since after detecting the S ripple through the regular hour after, building rocks judgment part 43 can remove the control of rocking acceleration/accel based on building in the size back of the acceleration/accel of judging the S ripple, so as long as after long yardstick component no longer is rocked, just can return to normal operation rapidly.Specifically, as long as detecting the size of the horizontal direction acceleration/accel compose operation value behind the S ripple shakes below the fatigue resistance at the allowed building of structure and mechanism of elevator, then after the releasing building rocks control, because rocking control, long yardstick parts involved in the present invention can bring into play its effect, so bring influence can for the function of the expection of elevator control operation.
In the above description, the threshold value of rocking judgment part 40 is configured to the mono-scale, but also can be by judgement zone 52 shown in Figure 4 is set, and whether the response coordinate figure of judging x, y direction has surpassed should the zone.
Below the long yardstick parts of explanation rock RESPONSE CALCULATION.Long period earthquake or high wind when taking place in long yardstick parts, along with rocking and produce, rocks in building, the intrinsic periodic band separately and the size thereof that are comprised in the motion of the periodic change that occurs when building rocks and long period seismic motion that is taken place and wind have certain relation, and the principal component of building slosh cycle remains the natural period of building top when rocking maximum.Therefore, long yardstick parts are at the natural period T of its natural period that rocks near building
0When (second), rock generation resonance with building, and cause it to rock increasing.
For example, aspect each long yardstick parts and building rock elevator car position when resonance takes place, when the position of lift car is near the bottom floor of building, the main hoist cable of lift car side easily and building rock and resonate, and when lift car is positioned at floor in the middle of the building, tension force less than the speed controller rope 8 of main hoist cable 7 and balance hoist cable 9 easily and building rock and resonate.So, long yardstick parts rock the influence that can be subjected to elevator car position, but to rock the degree that the infringement that causes takes place relevant with the rolling momentum of long yardstick parts because of long yardstick parts.Therefore, the vibrating mode of a plurality of natural perioies under the state that a natural period by having long yardstick parts and a natural period of building are close is calculated the rolling momentum, just can reach and carry out elevator control operation this purpose.
At this, it is relevant with the size of rocking of building that a natural period of building generally has its cycle, and along with elongated characteristic of its cycle of the increase of rocking.Building when high wind or long period earthquake rocks a natural period value of the building of acceleration/accel when the 30Gal left and right sides, the time will rocking acceleration/accel than the shatter-proof design of building, to be set in the natural period of the building of 200Gal when above slightly short, and the design value of natural period differs when providing high wind surely or the value during the long period seismic motion.And it is different that each of the minor face of building and long side direction rocks the natural period of building of direction.For this reason, change because of the minor face of building natural period and the periodic amplitude of long side direction and the size that building rocks for fear of the cycle, thereby bring difficulty for the prediction of rocking of long yardstick parts, so by adopting a plurality of long yardstick parts that constitute by natural period Ta, Tb, Tc to rock vibrating mode, improve the accuracy rate that rocks prediction, and predict the rolling momentum of long yardstick parts according to the rolling dynamic response of each described pattern, carry out the control operation with this.And, response data during according to the earthquake that observed, the natural period value of study building, and use the natural period of being acquired, regulate natural period Ta, the Tb of the vibrating mode that long yardstick parts rock, the value of Tc, to improve the precision of prediction of long yardstick parts transverse shakiness amount.
Rock at long yardstick parts aspect the attenuation characteristic of vibroseis; though each inscape of long yardstick parts is slightly different; but, then can guarantee to shake the real-time handling property of momentum calculating by adopting the general value to carry out stability Calculation to the rolling momentum of long yardstick parts.
The speed setting that the digital operation of arithmetic section 30 is handled becomes the such speed of all vibration respondings calculating of end in degree of will speed up analog signal conversion becomes sample period (second) of digital signal, and sets the real-time processing speed that the response of being obtained can be carried out in regular turn RESPONSE CALCULATION as the initial value in next calculation procedure for.And the sample period (second) is for example relevant with the shortest natural perioies (second) in predefined many group natural perioies, but needs only roughly about 0.01～0.03 second, just can keep the precision of RESPONSE CALCULATION.
According to said structure, that can judge each time point rocks the vibrating state of the long yardstick parts that produce because of building, so can be according to the seismic spread far away of focus ground the mode of rocking of the building in the incidental long period seismic motion and the lasting degree of rocking during to region of no relief with accumulation horizon, calculate increase degree and degree of damping that long yardstick parts rock in regular turn, can the long yardstick parts when considering earthquake or high wind rock and carry out high-precision elevator control on the basis of characteristics and move.
In the above-described embodiments, arithmetic section 30 has long yardstick parts and rocks the control function, but can know that building can rock etc. because of typhoon or powerful seasonal wind etc. in advance in the long period band time according to weather forecast, for fear of bringing uneasiness to the passenger, also can adopt elevator control operation is separated from the control scope of rocking judgment part 40, the operation result that long yardstick parts are rocked arithmetic section is presented on elevator monitoring dish in the building equipment monitoring room etc., thereby is judged the operation scheme of the control function that long yardstick parts rock by the elevator monitoring chamber.
As mentioned above, because the up-and-down movement of the earthquake at earthquake initial stage can increase in building, so detect on building top, compare with the occasion that in elevator hole 23, detects, accuracy of detection can be better, but detecting in the method for earthquake initial stage fine motion by first acceleration pick-up that is arranged on building top, being subjected to easily with lift facility and conditioning unit etc. is the influence of noise vibrations of the building inner machine equipment of representative.So, at other positions that can avoid subordinative building takes place with the vibrations of the noise on building top second acceleration pick-up is set separately, and according to the logic of these first and second acceleration pick-ups detected earthquake initial stage fine motion values with judge whether the initial stage fine motion of seismic motion arrives, then can not be subjected to the influence of noise vibrations and accurately detect the initial stage fine motion.And,, then also can use the P ripple detector 24 that is arranged in the elevator hole 23 if can avoid dependency taking place with the noise vibrations on building top.
Use long yardstick parts to rock control at the same time and building rocks control, and carry out under the situation of detection control of P ripple initial stage and the monitoring control of S ripple initial stage according to predefined P ripple threshold value and S ripple threshold value, when judgement initial stage fine motion, as shown in Figure 5, with the compose operation of the acceleration signal of all directions of carrying out x, y, z, for example with
Carrying out the signal of 3-axis acceleration compose operation part 46 of computing and the threshold value that building rocks judgment part 43 compares, can detect the initial stage fine motion that P ripple and S ripple mix, and the principal component of P ripple initial stage fine motion is a up-and-down movement, but when the long period earthquake takes place, because focus ground is far away, so also comprise the component of acceleration of horizontal direction.Therefore, by judging P ripple initial stage fine motion, then can improve the accuracy of detection of initial stage fine motion with the 3-axis acceleration composite signal.
In the above-described embodiments, vibration detector 5 is arranged in the Machine Room 21, but so long as can detect the position that building rocks, the not special restriction in position is set.And, in the above description, rock at long yardstick parts and to have adopted acceleration transducer signals in the computing, but also can the operating speed sensor signal, at this moment, only need to change the operational method of arithmetic section, just can rock in the computing and use at long yardstick parts.
