The specific embodiment
Below, with reference to accompanying drawing, the control running gear of elevator involved in the present invention and the embodiment of method thereof are elaborated.
The first embodiment
Fig. 1 is the constructional drawing of conventional lift.The lift facility of the present embodiment is configured to lift car 1 and counterbalanced weight 2 carries out lifting along not shown guide rail.Lift car 1 and counterbalanced weight 2 are hung as well-bucket shape by the main hoisting rope 7 that is wound in the winch 4 of the Machine Room 12 that is positioned at hoist trunk 11 tops, and are driven by main hoisting rope 7.In addition, in Machine Room 12, be provided with control panel 3, governor 6 and vibration meter 5, on governor 6, be wound with speed controller rope 8.In addition, when observing from elevator pusher side, be provided with the rope 9 for compensation for the weight difference of the main hoisting rope 7 of compensating elevator car 1 side and counterbalanced weight 2 sides.In addition be also provided with for the stern fast 10 to lift car 1 power supply.As mentioned above, in hoist trunk 11, be provided with main hoisting rope 7, speed controller rope 8, rope 9 and the isometric size objects of stern fast 10 for compensation.And, in hoist trunk 11, be also provided with guide rail and for making the not shown support of equipment etc. in hoist trunk.The operation of elevator is undertaken by having the remote operation of the controller 100 of the arithmetical devices such as CPU (Central Processing Unit, central processing unit).In addition, as described later, controller 100 reads the vibration meter 5 of Machine Room and calculates acceleration/accel, with the rolling momentum to the long size objects of each floor, carries out real time operation.
Fig. 2 represents the Computing Principle of the rolling momentum of long size objects of the present invention.Controller 100 adopts the equation of motion of the simple substance point single degree of freedom model of vibration of long size objects to calculate each long size objects (for example main hoisting rope, compensation rope and speed controller rope) with respect to the relative rolling momentum of building.While approaching the natural period of building due to the natural period at long size objects, can produce the phenomenon of rocking increasing of long size objects, so a plurality of points in the natural period of the approaching building of controller 100 use and the natural period of long size objects carry out the rolling momentum of the long size objects of computing.For example, when high wind or during earthquake, at vibration meter 5, detect after vibration, controller 100 is according to the size of the detection signal of this vibration meter 5, adopt above-mentioned a plurality of model (adopting five models of displacement Xn-2～Xn+2 in the example shown in Fig. 2), with respect to the building that has occurred to rock, rock the acceleration/accel acceleration/accel of Machine Room (in the example shown in Fig. 2 with respect to), at each floor (be 1 layer to n layer), calculate in real time the relative rolling momentum of the long size objects of each model in the example shown in Fig. 2, and the contingent maximum momentum that shakes using its maxim as long size objects is calculated.
More specifically, when the natural period of building is set as to Tb, controller 100 as shown in Figure 2, the long size objects of computing is at rolling momentum (displacement) Xn of this natural period, computing extends Δ α 1 by the natural period Tb of building and the rolling momentum Xn+1 of the long size objects of the natural period Tb+ Δ α 1 that obtains, and the rolling momentum Xn+2 of the long size objects of computing natural period Tb+ Δ α 2 that the natural period Tb prolongation Δ α 2 of building is obtained.In contrast, controller 100 also computing dwindles Δ α 1 by the natural period Tb of building and the rolling momentum Xn-1 of the long size objects of the natural period Tb-Δ α 1 that obtains, and the rolling momentum Xn-2 of the long size objects of computing natural period Tb-Δ α 2 that the natural period Tb shortening Δ α 2 of building is obtained.And, controller 100 is defined as the maximum momentum that shakes for each floor by the maximum rolling momentum (displacement) in the rolling momentum of above-mentioned long size objects, and whether determined this rolling momentum of real-time judge has exceeded the threshold value of being specified in advance and be stored in the storage parts such as memory device that controller 100 has by client.
For example, the maxim Xn of rolling momentum that calculates the long size objects of 5F at controller 100 in certain time point has reached the predetermined threshold value on opportunity with natural period Tb, and the maxim Xn+1 of the rolling momentum of the long size objects of 6F will reach this threshold value the opportunity at natural period Tb+ Δ α 1, now, this time point only have 5F be resonance floor, and be predicted as 6F soon (on the opportunity of natural period Tb+ Δ α 1) also may become resonance floor.Therefore, controller 100 is judged as 5F and 6F elevator can not be stopped, and does not stop above-mentioned floor at the control elevator that makes in service.As mentioned above, controller 100 carries out same computing for all floors of building, judges whether to exist the rolling momentum of long size objects to reach predetermined threshold value or be predicted to be and will reach the floor of predetermined threshold value.And, in the situation that being judged as, controller 100 exist the rolling momentum of long size objects to reach this threshold value or be predicted to be and will reach the floor of this threshold value, this floor is judged as to the resonance floor of this time point, and prediction equally also will occur that the rolling momentum of long size objects surpasses the floor of this threshold value in other cycle soon, and this floor may become on this opportunity resonance floor.Now, the operation of elevator is controlled, made elevator not stop above-mentioned floor.
It should be noted that, when controller 100 is judged as the rolling momentum of the long size objects going out according to each mode computation what in office according to the result of above-mentioned calculating in cycle (being 5 cycles in the example shown in Fig. 2), does not all reach predetermined threshold value or be predicted to be can not reach this threshold value time, this floor is judged as to off-resonance floor, makes elevator parking at this floor.
Fig. 3 is the diagram of circuit of the control operation in the control running gear of elevator of present embodiment.As shown in Figure 3, controller 100 is when vibration meter 5 detects building and occurred to rock because of high wind or earthquake (S301), as shown in Figure 2, for each floor, calculate the rolling momentum of long size objects, judged whether to occur to reach predetermined threshold value or be predicted to be to reach the rocking of long size objects (S302) of this threshold value.
And, when controller 100 is judged as in any floor and any cycle all less than occurring to have reached this threshold value or being predicted to be (S302 is No) when the long size objects that reaches this threshold value is rocked, be judged as long size objects and do not shake, make elevator proceed common operation (S304) according to speed before this.On the other hand, at controller 100, be judged as at any floor and occurred to reach predetermined threshold value or be for example predicted to be, by the long size objects that reaches this threshold value (main hoisting rope on the opportunity in any cycle of each model shown in Fig. 2, during rocking any in rope and speed controller rope for compensation) (S302 is Yes), carry out control operation, make the interim stop of elevator that the nearest off-resonance floor in off-resonance floor that above-mentioned long size objects rocks not occur, and do not stop and above-mentioned long size objects has occurred rock or be predicted to be the floor (S306) rocking there is above-mentioned long size objects.For example, suppose when vibration meter 5 detects rocking of building, elevator is positioned near 7 layers of building of 10 floors, and suppose that off-resonance floor is 1～3 layer and 8～10 layers, controller 100 carries out control operation, make elevator parking after 8 layers, nearest off-resonance floor, only 1～3 layer, off-resonance floor and 8～10 layers, stop, and at 4～7 layers, do not stop.
After this, the rocking whether to have converged to of the long size objects of controller 100 judgement is less than the degree of above-mentioned threshold value or is predicted to be the degree (S307) that is less than above-mentioned threshold value by converging to, when being judged as rocking of long size objects, also not converging to and be less than the degree of above-mentioned threshold value or be not also predicted to be when converging to the degree that is less than above-mentioned threshold value (S307 is No), proceed above-mentioned control operation.On the other hand, controller 100 has converged to and is less than the degree of above-mentioned threshold value or is predicted as when converging to the degree that is less than above-mentioned threshold value (S307 is Yes) being judged as rocking of long size objects, from control operation, switches to common operation (S304).So, due to the rocking after convergence of long size objects, controller 100 makes operational mode return to common operation automatically, thus the impact of rocking can be controlled in Min., thus can make elevator trouble-free operation.
As mentioned above, in the present embodiment, controller 100 is controlled by the operation shown in Fig. 3, using threshold value as benchmark, carry out the control operation in a stage, when building has occurred to rock, if the long size objects that vibration meter 5 did not all detect more than predetermined threshold value in any floor and any cycle rocks, or when not being predicted as long size objects more than predetermined threshold value and rocking, make elevator proceed common operation, on the other hand, if vibration meter 5 rocks to the long size objects more than predetermined threshold value at any floor and any cycle detection, or be predicted as when long size objects more than predetermined threshold value being detected and rock, carry out control operation, make the nearest off-resonance floor of the interim stop of elevator, and do not stop resonance floor.Thus, lift facility that can be in hoist trunk can not make lift car slow down in the scope sustaining damage and out of service because long size objects rocks as far as possible, and continues as off-resonance floor service is provided.That is to say, controller 100 can carry out control operation, make when the rolling momentum of the long size objects that has reached arbitrarily predetermined threshold value being detected, comprise soon and will become the floor of resonance floor, by the disposable not dock floor that is set as of resonance floor, for off-resonance floor, can continue the service that provides running velocity constant, even if building has occurred to rock when earthquake and during high wind, also can suitably make elevator carry out operation conventionally.
It should be noted that, in step S307, controller 100 judgement converges to after being less than threshold value whether passed through the predetermined fixed time at the rolling momentum of long size objects, when after this identical threshold value not detected, automatically makes restoring running arrive common operation.In addition, in order preferentially to make elevator return to common operation, the process fixed time such as also can be arranged to not just make elevator return to common operation.In addition, when setting above-mentioned threshold value, by controller 100, according to the cutaway view of hoist trunk, obtained the minimum value in the gap between equipment in long size objects and hoist trunk, and pre-determine accordingly above-mentioned threshold value, make it possible to carry out control operation before long size objects contacts with equipment in hoist trunk.In addition, in above-mentioned example, the rolling momentum of the long size objects of computing near 5 cycles natural period of building, but also can increase and decrease according to the number of floor levels of building the quantity (for example increase the quantity of model at skyscraper, reduce the quantity of model at highly not high building) of model.
The second embodiment
In above-mentioned the first embodiment, at the long size objects that predetermined threshold value has occurred to surpass, rock or be predicted to be when the above-mentioned long size objects of generation rocked, controller 100 control elevators, make elevator not stop all resonance floors., when the most of floors in all floors are resonance floor, sometimes because the floor of not stopping too much not necessarily can improve passenger's convenience.In order to address this problem, elevator is controlled, make elevator periodically by resonance floor, below the method is described.It should be noted that, because the structure of lift facility is identical with the situation of the first embodiment, so the description thereof will be omitted at this.Referring to diagram of circuit, the control method of the control operation of the present embodiment is described.
As shown in Figure 4, controller 100 is identical with the situation of the first embodiment, after each processing of carrying out step S301～S304, for example judged whether to reach, in the threshold value (with the maximum that is less than long size objects shake threshold value (grade 1) corresponding to the rolling momentum of momentum and these two threshold values of threshold value (grade 2) corresponding with the maximum rolling momentum of long size objects) of predetermined a plurality of grades any threshold value or no being predicted to be will reach any threshold value (step S305) in above-mentioned threshold value, when being judged as, having reached the threshold value corresponding with grade 1 or be predicted to be and will reach the threshold value corresponding with grade 1, but do not reach the threshold value corresponding with grade 2 or be not predicted to be when reaching the threshold value corresponding with grade 2, operation to elevator is controlled, make elevator only by rolling momentum, reach the threshold value of grade 1 or be predicted to be the floor that reaches the threshold value of grade 1 (step S401).On the other hand, when being judged as, having reached the threshold value corresponding with grade 2 or be predicted to be when reaching the threshold value corresponding with grade 2, the operation of 100 pairs of elevators of controller is controlled, and making elevator by all rolling momentum, reach the threshold value of grade 1 and grade 2 or be predicted to be will reach the floor (step S402) of the threshold value of grade 1 and grade 2.
For example, suppose when vibration meter 5 detects rocking of building, elevator is positioned near 8 layers of building of 10 floors, and suppose to have reached with the maximum of grade 2 and shake threshold value corresponding to momentum or be predicted to be that to shake the floor of threshold value corresponding to momentum with the maximum of grade 2 be 5～6 layers by reaching, reached with the maximum that is less than grade 1 and shaken threshold value corresponding to the rolling momentum of momentum or be predicted to be that to shake the floor of threshold value corresponding to the rolling momentum of momentum with the maximum that is less than grade 1 be 3～4 layers and 7 layers by reaching, and other floor is off-resonance floor.Now, controller 100 is controlled, and makes elevator after stopping 8 layers, nearest off-resonance floor, if the rocking as grade 2 of long size objects, controller 100 is controlled, and makes elevator pass through all floors in 3～7 layers.On the other hand, when long size objects rock as grade 1 time, controller 100 is controlled, and makes elevator after stopping 8 layers, nearest off-resonance floor, only by 5～6 layers (stopping 3～4 layers and 7 layers).
After this, controller 100 is identical with the situation of the first embodiment, judge degree or the no degree (S307) that is less than this threshold value by converging to that is predicted to be that is less than the threshold value corresponding with above-mentioned grade 1 and grade 2 that whether converged to of rocking of long size objects, when being judged as rocking of long size objects, also not converging to than the little degree of above-mentioned threshold value or be not also predicted to be when converging to the degree that is less than this threshold value (S307 is No), proceeding above-mentioned control operation.On the other hand, controller 100 converges to than the little degree of above-mentioned threshold value or is predicted to be when converging to the degree that is less than this threshold value (S307 is Yes) when being judged as rocking of long size objects, from control operation, is switched to common operation (S304).As mentioned above, because making operational mode automatically, controller 100 returns to common operation, thus the impact of rocking can be controlled in Min., thus can make elevator trouble-free operation.
As mentioned above, in a second embodiment, controller 100 arranges a plurality of predetermined threshold values, and according to each threshold value, elevator is carried out to interim control operation, when vibration meter 5 detects the long size objects that has surpassed the threshold value corresponding with each grade, rock or be predicted to be when the long size objects that surpasses the threshold value corresponding with each grade is rocked, the time point that the long size objects corresponding with each grade detected and rock, or by surpassing the time point that this long size objects rocks, make after the nearest off-resonance floor of the temporary transient stop of elevator being predicted to be, do not stop the control operation of resonance floor, can periodically reduce service available off-resonance floor thus, thereby can avoid the service available floor quantity of elevator to reduce quickly, can relax the deterioration of passenger convenience thus.
It should be noted that, controller 100 is identical with the situation of the first embodiment, in step S307, judgement converges to after being less than threshold value whether passed through the predetermined fixed time at the rolling momentum of long size objects, when after this identical threshold value not detected, automatically make restoring running arrive common operation.In addition, in order preferentially to make elevator return to common operation, the process fixed time such as also can be arranged to not just make elevator return to common operation.In addition, when setting above-mentioned threshold value, by controller 100, according to the cutaway view of hoist trunk, obtained the minimum value at the interval between equipment in long size objects and hoist trunk, and pre-determine accordingly above-mentioned threshold value, make it possible to carry out control operation before long size objects contacts with equipment in hoist trunk.In addition, in above-mentioned example, near the rolling momentum of 5 long size objects of the cycle computing natural period of building, but also can increase and decrease according to the number of floor levels of building the quantity (for example increase the quantity of model at skyscraper, reduce the quantity of model at highly not high building) of model.
The 3rd embodiment
In above-mentioned the second embodiment, 100 pairs of elevators of controller carry out interim control operation and control, but in addition for example also there is following situation: in the situation that the maximum of long size objects rolling momentum has reached the threshold value of grade 2 or has been predicted to be and will reach the threshold value of grade 2, if it is excessive to surpass the degree of this threshold value, can cause long size objects to sustain damage.Therefore, in order to tackle this situation, further arrange and represent that rolling momentum has exceeded the much degree of max-thresholds or has been predicted to be the baseline threshold that exceeds much degree (grade 3), when the rolling momentum of long size objects has reached this threshold value or has been predicted to be when reaching this threshold value, controller 100 forcibly makes elevator out of service.Below above-mentioned situation is described.Because the structure of lift facility is identical with the situation of the first embodiment and the second embodiment, so the description thereof will be omitted at this.Referring to diagram of circuit, the control method of the control operation of the present embodiment is described.
As shown in Figure 5, controller 100 is identical with the situation of the first embodiment and the second embodiment, after each processing of carrying out step S301～S304, the threshold value that has judged whether to reach predetermined a plurality of grades (is for example shaken threshold value (grade 1) corresponding to the rolling momentum of momentum with the maximum that is less than long size objects, shake threshold value (grade 2) corresponding to momentum and threshold value (grade 3) this three threshold values corresponding with the rolling momentum that significantly surpasses grade 2 with the maximum of long size objects) in any threshold value or no being predicted to be will reach any threshold value (step S305) in above-mentioned threshold value, when being judged as, having reached the threshold value corresponding with grade 1 or be predicted to be when reaching the threshold value corresponding with grade 1, identical with the situation of the second embodiment, operation to elevator is controlled, making elevator not stop rolling momentum has reached the threshold value of grade 1 or has been predicted to be and will reach each floor (step S401) of the threshold value of grade 1.
On the other hand, although although will reach the threshold value corresponding with grade 1 but also not reach the threshold value corresponding with grade 2 or be not predicted to be when reaching the threshold value corresponding with grade 2 when being judged as to have reached the threshold value corresponding with grade 1 or be predicted to be, identical with the situation of the second embodiment, the operation of 100 pairs of elevators of controller is controlled, and makes elevator not stop all rolling momentum and has reached the threshold value of grade 1 or be predicted to be the floor that reaches the threshold value of grade 1 (step S402).
In addition, when shaking momentum, reached the threshold value corresponding with grade 2 or be predicted to be when reaching the threshold value corresponding with grade 2, what controller 100 was obtained this threshold value exceeds the degree deviation value of this threshold value (for example with), and judge whether rolling momentum has reached threshold value or no be predicted to be corresponding with grade 3 and will reach the threshold value corresponding with grade 3, when being judged as, shaking the degree of momentum and reached the threshold value corresponding with grade 3 or be predicted to be when reaching the threshold value corresponding with grade 3, make the nearest off-resonance floor of elevator parking, and make elevator temporarily (step S501) out of service.After this, at controller 100, being judged as rocking of long size objects has converged to and is less than the degree of the threshold value corresponding with grade 1 and grade 2 or is predicted to be and will converge to after the degree being less than with grade 1 and threshold value corresponding to grade 2, by loud speaker and monitoring device etc., by the information that requires maintainer to implement maintenance, notify maintainer, make thus maintainer manually overhaul (step S502).Then,, after maintainer overhauls, in the situation that elevator does not note abnormalities and receives the instruction that restarts operation, controller 100 is switched to common operation (step S304) by operation.
It should be noted that, controller 100 is identical with the situation of the first embodiment and the second embodiment, judge degree or the no degree (step S307) that is less than this threshold value by converging to that is predicted to be that is less than the threshold value corresponding with above-mentioned grade 1 and grade 2 that whether converged to of rocking of long size objects, when being judged as rocking of long size objects, converging to than the little degree of above-mentioned threshold value or be predicted to be when converging to the degree that is less than this threshold value (step S307 is Yes), the operation of elevator is switched to common operation (step S304).On the other hand, controller 100 be judged as rocking of long size objects also do not converge to be less than the degree of any threshold value in the threshold value corresponding with grade 1 or grade 2 or be not predicted to be by converge to be less than with grade 1 or threshold value corresponding to grade 2 in the degree of any threshold value time (step S307 is No), make elevator proceed control operation.As mentioned above, due to controller 100 long size objects rock convergence after automatically make operational mode return to common operation, so the impact of rocking can be controlled to Min., thereby can make elevator trouble-free operation.
For example, suppose when vibration meter 5 detects rocking of building, elevator is positioned near 8 layers of building of 10 floors, and suppose to have reached with the maximum of grade 2 and shake threshold value corresponding to momentum or be predicted to be that to shake the floor of threshold value corresponding to momentum with the maximum of grade 2 be 5～6 layers by reaching, reached with the maximum that is less than grade 1 and shaken threshold value corresponding to the rolling momentum of momentum or be predicted to be and shake threshold value corresponding to the rolling momentum of momentum by reaching with the maximum that is less than grade 1, but also do not reach and shake threshold value corresponding to momentum or be predicted to be with the maximum of grade 2 and can not reach that to shake the floor of threshold value corresponding to momentum with the maximum of grade 2 be 3～4 layers and 7 layers, in addition, suppose that the maximum momentum that shakes has not only reached the threshold value of grade 2 or has been predicted to be and will reach the threshold value of grade 2, but also reached the threshold value of grade 3 or be predicted to be the floor that arrives the threshold value of grade 3, be 6F, other floor is off-resonance floor.Now, because the rolling momentum of a part of floor of building (6 layers) has reached the threshold value of grade 3 or has been predicted to be the threshold value that will arrive grade 3, so controller 100 makes elevator after stopping 8 layers, nearest off-resonance floor, make elevator out of service.Rocking after convergence of long size objects, maintainer checks, maintainer, confirms after safety, and the instruction that controller 100 receives from maintainer, switches to common operation again by operation.In addition, when rocking of long size objects reached rocking or being predicted to be when reaching the rocking of grade 1 and grade 2 of grade 1 and grade 2, identical with the situation of the second embodiment, controller 100 is controlled, make elevator after stopping 8 layers, nearest off-resonance floor, only by 5～6 layers (stopping 3～4 layers and 7 layers).In addition, controller 100 is controlled, and makes elevator pass through all floors in 3～7 layers.
As mentioned above, in the 3rd embodiment, the situation of the control of controller 100 under the larger shaking amplitude of the deviation value of the operating distance of the control of the carrying out above-mentioned stage threshold value corresponding with grade 2 operation (the rolling momentum in the example shown in Fig. 5 has reached the threshold value corresponding with grade 3 or has been predicted to be and will reach the situation of the threshold value corresponding with grade 3), is judged as for the equipment of elevator operation may be sustained damage because of rocking of long size objects.Now, even after the rolling momentum convergence of long size objects, controller 100 does not make elevator automatically restore to common operation yet, and it is out of service that elevator is run to after nearest off-resonance floor, after maintainer's maintenance and confirming safely, by manually making elevator return to common operation.Thus, can when guaranteeing safety, periodically reduce service available off-resonance floor, identical with the situation of the second embodiment, can avoid the service available floor quantity of elevator to reduce quickly, can relax thus the deterioration of passenger convenience.
It should be noted that, controller 100 is identical with the situation of the first embodiment and the second embodiment, in step S307, judgement converges to after being less than threshold value whether passed through the predetermined fixed time at the rolling momentum of long size objects, when after this identical threshold value not detected, automatically make restoring running arrive common operation.In addition, in order preferentially to make elevator return to common operation, the process fixed time such as also can be arranged to not just make elevator return to common operation.In addition, when setting above-mentioned threshold value, by controller 100, according to the cutaway view of hoist trunk, obtained the minimum value at the interval between equipment in long size objects and hoist trunk, and pre-determine accordingly above-mentioned threshold value, make it possible to carry out control operation before long size objects contacts with equipment in hoist trunk.In addition, in above-mentioned example, near the rolling momentum of 5 long size objects of the cycle computing natural period of building, but also can increase and decrease according to the number of floor levels of building the quantity (for example increase the quantity of model at skyscraper, reduce the quantity of model at highly not high building) of model.
The 4th embodiment
In above-mentioned the second embodiment and the 3rd embodiment, elevator is controlled, make periodically to reduce service available off-resonance floor, can avoid thus passenger's convenience to suffer damage.; in the situation that be judged as rolling momentum, reached the threshold value of grade 1 or grade 2 or be predicted to be and will reach the threshold value of grade 1 or grade 2; if the rolling momentum of long size objects does not converge to the degree that is less than the threshold value corresponding with above-mentioned level, elevator does not switch to common operation.Now, possibly cannot make the operation scheme of elevator in best running state.In order to tackle this situation, to be arranged in, detect after the rocking of long size objects through in the situation of regular hour, if the long size objects corresponding with the threshold value of same levels detected, do not rock, the grade of the control operation of elevator is lowered to one-level.Below this situation is described.Because the structure of lift facility is identical with the situation of the first embodiment～three embodiment, so the description thereof will be omitted at this.Referring to diagram of circuit, the control method of the control operation of the present embodiment is described.
As shown in Figure 6, controller 100 is identical with the situation of the second embodiment and the 3rd embodiment, carry out each processing of step S301～S304, after this judge whether to have reached the threshold value (threshold value (grade 1) corresponding with being less than the maximum rolling momentum that shakes momentum for example of predetermined a plurality of grades, shake threshold value (grade 2) corresponding to momentum and threshold value (grade 3) this three threshold values corresponding with the rolling momentum that significantly surpasses grade 2 with the maximum of long size objects) in any threshold value or no being predicted to be will reach any threshold value (step S305) in this threshold value, when being judged as, having reached the threshold value corresponding with grade 2 or be predicted to be when reaching the threshold value corresponding with grade 2, through after the preassigned time, again judge whether to detect and arrived the threshold value of grade 2 or be predicted to be and will reach the rolling momentum (step S601) of the threshold value of grade 2.Controller 100 be judged as again do not detect arrived the threshold value of grade 2 or be predicted to be by reach grade 2 the rolling momentum of threshold value time (step S601 is No), enter step S401, operation to elevator is controlled, the grade of the control operation of elevator is lowered to one-level, make elevator only by rolling momentum, reach the threshold value of grade 1 or be predicted to be and will reach each floor of the threshold value of grade 1.
After this, controller 100 enters step S307, identical with the situation of the first embodiment～three embodiment, judge degree or the no degree (step S307) that is less than this threshold value by converging to that is predicted to be that is less than the threshold value corresponding with above-mentioned grade 1 that whether converged to of rocking of long size objects, when being judged as rocking of long size objects, converging to than the little degree of this threshold value or be predicted to be when converging to the degree that is less than this threshold value (step S307 is Yes), the operation of elevator is switched to common operation (step S304).On the other hand, controller 100 does not also converge to and is less than the degree of this threshold value or is not predicted to be when converging to the degree that is less than this threshold value (step S307 is No) being judged as rocking of long size objects, makes elevator proceed control operation.As mentioned above, due to controller 100 long size objects rock convergence after automatically make operational mode return to common operation, so the impact of rocking can be controlled in Min., thereby can make elevator trouble-free operation.
As mentioned above, in the 4th embodiment, when vibration meter 5 detects threshold value corresponding to the grade with larger in the threshold value that has reached corresponding with a plurality of grades or is predicted to be when arriving the rocking of long size objects of this threshold value, through after the preassigned time, in the situation that again do not detect, arrived the threshold value corresponding with identical grade or be not predicted to be and will reach the rocking of long size objects of the threshold value corresponding with identical grade, the operation of 100 pairs of elevators of controller is controlled, the grade of the control operation of elevator is lowered to one-level, make elevator only by shaking momentum, reach the threshold value corresponding with lower grade or be predicted to be and will reach each floor of the threshold value corresponding with lower grade.Thus, can confirm in real time the rocking of long size objects of this time point, can provide suitable elevator service according to the situation of rocking of long size objects, can relax thus the deterioration of passenger convenience simultaneously.
It should be noted that, as shown in Figure 6, when the rolling momentum of long size objects has reached the threshold value corresponding with grade 3 or has been predicted to be when reaching the threshold value corresponding with grade 3, because lift facility may sustain damage because of rocking of long size objects.Now, even converge to the threshold value corresponding with lower grade or be predicted to be when converging to the threshold value corresponding with lower grade at the rolling momentum of long size objects, do not make elevator automatically restore to common operation yet, and it is out of service that elevator is run to after nearest off-resonance floor, after maintainer's maintenance and confirming safely, by manually making elevator return to common operation.
After this, controller 100 is identical with the situation of the first embodiment～three embodiment, in step S307, judgement converges to after being less than threshold value whether passed through the predetermined fixed time at the rolling momentum of long size objects, when after this identical threshold value not detected, automatically make restoring running arrive common operation.In addition, in order preferentially to make elevator return to common operation, the process fixed time such as also can be arranged to not just make elevator return to common operation.In addition, when setting above-mentioned threshold value, by controller 100, according to the cutaway view of hoist trunk, obtained the minimum value at the interval between equipment in long size objects and hoist trunk, and pre-determine accordingly above-mentioned threshold value, make it possible to carry out control operation before long size objects contacts with equipment in hoist trunk.In addition, in above-mentioned example, near the rolling momentum of 5 long size objects of the cycle computing natural period of building, but also can increase and decrease according to the number of floor levels of building the quantity (for example increase the quantity of model at skyscraper, reduce the quantity of model at highly not high building) of model.
The present invention is not subject to the restriction of above-described embodiment, can comprise various variation.For example, the present invention will be described in detail for the mode to be easily understood for above-described embodiment, but do not mean that the present invention must have all structures of carrying out explanation.For example, in the 4th embodiment, the threshold value corresponding with two grades of take controlled the operation of elevator as prerequisite, make elevator only by rolling momentum, from the threshold value with higher level is corresponding, be reduced to each floor corresponding with the threshold value of lower grade, but also can between the threshold value that is divided into more than 3 stage, carry out above-mentioned control etc.In addition, a part of structure of certain embodiment can be replaced with to the structure of other embodiment, also the structure of other embodiment can be appended in the structure of some embodiment, also can a part of structure of each embodiment be appended, be deleted and be replaced by other structures.
