Fig. 3 is sensor unit 2 in the concrete presentation graphs 1 and the block scheme of each control setup 8.Each control setup 8 has: the master control part 8a that controls the action of each control setup 8 integral body; The 1st rope vibrations detecting unit (cord traverse shake detecting unit) 8b and the 2nd rope vibrations detecting unit 8c for detection of the generation of the vibration of main rope 5; The 8d of Parameter storage section; The pattern select switch 8e that selects one to switch to the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c; Monitor the car position monitoring unit 8f of the position of car 6; Controlled operation mode selection part 8g with the content that is used for definite controlled operation.The 1st rope vibrations detecting unit 8b comprises acceleration levels operational part 8h and comparing section 8i.The 2nd rope vibrations detecting unit 8c comprises the 8j of timer section, building mean amplitude of tide operational part 8k and rope amplitude amount operational part 8l.

The information of the resonant position D1～D4 of pre-stored the 2nd parameter that the 1st parameter used by the 1st rope vibrations detecting unit 8b is arranged, used by the 2nd rope vibrations detecting unit 8c, car 6 and being used for makes the information of retreating position (the keeping out of the way floor) E that car 6 keeps out of the way in the 8d of Parameter storage section.Wherein, resonant position D1～the D4 of car 6 (with reference to the oblique line position among Fig. 1) refers to when building 1 shook according to a natural period of oscillation, the position of the car 6 when the arbitrary rope in main rope 5, counterweight rope 7 and the speed controller rope 10 and building 1 resonance.Specifically, resonant position D1 refers to the position of shaking the car 6 when resonating of main rope 5 and the building 1 of car 6 sides, and resonant position D1 is disposed near the bottom of hoistway 1a.Resonant position D2 refers to the position of shaking the car 6 when resonating of counterweight rope 7 and building, and resonant position D2 devices spaced apart is configured in resonant position D1 top.Resonant position D3 refers to the position of shaking the car 6 when resonating of speed controller rope 10 and building 1, and resonant position D3 devices spaced apart is configured in resonant position D2 top.Resonant position D4 refer to the main rope 5 of heavy side and building 1 shake resonance the time the position of car 6, resonant position D4 is disposed near the bottom of machine room 1b.On the other hand, the retreating position E of car 6 refers to that the retreating position E of car 6 is configured between resonant position D3 and the resonant position D4 be used to avoiding each rope 5,7,10 and the position of the car 6 of the resonance of building 1.In addition, these resonant positions D1～D4 and retreating position E are the positions of measuring in advance.

Controlled operation mode selection part 8g sends the switching command that is used for the running of car 6 is switched to from common running controlled operation according to from the S ripple detection information of sensor unit 2 or the contents processing of P detection information or the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c to master control part 8a.Wherein, controlled operation is when building 1 shakes, and the speed of car 6 is lower than usually and continues to advance or makes car 6 in advancing rest in nearest floor or make car 6 emergent stoppings or make car 6 rest in the drive manner of retreating position E.Car position monitoring unit 8f monitors the position of car 6 according to the impulse singla from the impulse deviser on the S. A. that is installed in towing machine 3 (not shown).

Below, illustrate that the 1st rope vibrations detecting unit 8b detects the principle of rope vibrations (lateral shake).Fig. 4 is the building displacement z of expression in the general elevator and the diagram of curves of the relation of rope amplitude V and time t.The diagram of curves of the building displacement z when Fig. 5 is expression use the 1st rope vibrations detecting unit 8b and the relation of rope amplitude V and time t.The diagram of curves of the building acceleration/accel a when Fig. 6 is expression use the 1st rope vibrations detecting unit 8b and the relation of rope amplitude V and time t.In addition, Fig. 4,5 the longitudinal axis represent building displacement z and rope amplitude V, and the longitudinal axis of Fig. 6 represents building acceleration/accel a and rope amplitude V, and the transverse axis of Fig. 4～6 represents time t.

In Fig. 4, when building 1 was fixed the pure oscillation of amplitude according to a natural period of oscillation T, the amplitude of main rope 5 was that rope amplitude V increased along with the time.When the sensor unit 2 that shakes, is located at building 1 at building 1 detects shaking of building 1, carry out the controlled operation of cars 6 by each control setup 8, the car 6 in advancing advances to nearest floor, and car 6 rests in this floor.During this situation, if shake the time t that car 6 arrives nearest floor and rests against this from building 1 ₀Long, then the vibration of the horizontal direction of main rope 5 can be followed advancing of car 6 and increase.Wherein, if the minor increment that contacts with equipment in the hoistway by the end of main rope 5 is made as minimal-contact amplitude (permission shaking quantity) V ₀, then in situation shown in Figure 4, arrive nearest floors and rest against this time t by the end of car 6 ₀Long, so before car 6 arrived nearest floor, rope amplitude V namely surpassed minimal-contact amplitude V ₀, main rope 5 contacts with the interior equipment of the hoistway in the hoistway 1a.Therefore, the hooking that causes producing main rope 5 with because of the damage of main rope 5 with equipment in equipment in the hoistway contacts the hoistway that causes, advancing of car 6 brought obstacle.

On the other hand, in Fig. 5, in the building displacement z that shakes of the building stage less than the building displacement z1 among Fig. 4, namely in stage of building displacement z2, if each control setup 8 is implemented the controlled operation of car 6, then at the time t that car 6 arrives nearest floors and rests against this that shakes from generation building 1 ₀During this time, rope amplitude V is less than situation shown in Figure 4, and rope amplitude V can not surpass minimal-contact amplitude V ₀Like this, distinguish in order to make car 6 rest in safely nearest floor, need to be according to a natural period of oscillation T of building 1, from the time t that car 6 arrives nearest floor that shakes of building 1 occurs ₀, and the minimal-contact amplitude V of main rope 5 ₀, be identified for the building displacement z or the building acceleration/accel a that make car 6 rest in nearest floor.

In addition, this sentences worst case evaluation, for the time t that car 6 arrives nearest floors and rests against this that shakes from generation building 1 ₀, use the longest between the floor, namely by the end of car 6 arrive nearest floors and rest against the value the longest standing time of this required time when the longest (below be made as the longest standing time t ₀).And, for the minimal-contact amplitude V of main rope 5 ₀, use until the distance that contacts with hoistway equipment is the shortest amplitude (the minimum shaking quantity that allows).Thus, under any state, can both make car 6 rest in safely nearest floor.These values are values of measuring in advance, are contained in the 1st parameter of storing in the 8d of Parameter storage section.

Acceleration levels operational part 8h uses a natural period of oscillation T, the minimal-contact amplitude V of building ₀The longest standing time t ₀, calculate the 1st acceleration levels a according to following formula (1) ₁And acceleration levels operational part 8h is the 1st acceleration levels a ₁2 times be calculated as the 2nd acceleration levels a ₂

[formula 1]

a ₁=(4 ω) * (α V ₀)/t ₀(1) formula

Wherein, ω represents the eigentone of building, ω=2 π/T.α represents by the end of minimal-contact amplitude V ₀The amplitude surplus, the scope of the value of α is 0＜α＜1.

Comparing section 8i will based on the building acceleration/accel a of the building 1 of the vibration detecting information that receives from sensor unit 2, with the 1st acceleration levels a ₁With the 2nd acceleration levels a ₂Compare.In addition, bandpass filter (not shown) utilizes this bandpass filter to send near the information of the acceleration/accel the eigentone of the building 1 in the vibration detecting information to 8 of each control setups between sensor unit 2 and Ge Tai control setup 8.And except the allergic reaction that will cause because of the single vibration of building 1, comparing section 8i has surpassed the 1st acceleration levels a confirming building acceleration/accel a ₁The time, building acceleration/accel a is surpassed the 1st acceleration levels a ₁Number of times count.And, as shown in Figure 6, along with building acceleration/accel a many times (times N, N is the integer more than 2) surpasses the 1st acceleration levels a ₁, comparing section 8i notice controlled operation mode selection part 8g begins to carry out the controlled operation of car 6.Controlled operation mode selection part 8g receives when beginning to carry out the information of controlled operation, sends the execution instruction of controlled operation to master control part 8a.

On the other hand, although be single vibration building acceleration/accel a when larger to a certain degree, rope amplitude V can surpass minimal-contact amplitude V sometimes ₀For this situation, comparing section 8i surpasses the 2nd acceleration levels a at building acceleration/accel a ₂The time, the number of times that surpasses of building acceleration/accel a is not counted, but notice controlled operation mode selection part 8g begins to carry out the controlled operation of car 6.When controlled operation mode selection part 8g receives the information of the controlled operation of carrying out car 6 since the 1st rope vibrations detecting unit 8b, send controlled operation to master control part 8a and carry out instruction, master control part 8a begins the controlled operation (controlled operation of using for phugoid) of car 6.The controlled operation of the car 6 of this moment is a kind of drive manners as follows, car 6 in advancing is moved to nearest floor, after this car 6 arrives nearest floor, make car 6 open door, the broadcast that loud speaker (not shown) in car 6 is exported lower elevator, urge thus the passenger of car 6 to go out elevator (driving action out of), from open the door through the schedule time after, car 6 is closed the door.

At this, in situation shown in Figure 6, at relative the 1st Looking Out Time t of the cycle T of vibration of building ₁(t ₁=T * N, N=positive integer) in time, surpasses at least the 1st acceleration levels a more than 2N time at building acceleration/accel a ₁The time, can think shaking of building 1 that phugoid causes occured.In addition, if with the 1st Looking Out Time t ₁Set longlyer, then might cause the vibration of main rope 5 to increase, so preferred the 1st Looking Out Time t ₁Be the longest standing time t ₀Below (namely resting in the needed maximum duration of nearest floor by the end of car 6).

In addition, hang down acceleration detection information at each control setup 8 according to the spy from sensor unit 2, low acceleration detection information, or during special low acceleration detection information and executing controlled operation, by making the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c continue to play a role, automatic replacement behind the controlled operation of corresponding special low acceleration detection information, remote reset behind the controlled operation of corresponding low acceleration detection information, after manual replacement behind the controlled operation of corresponding high acceleration detection information, also can monitor the situation that building 1 continues to shake because of phugoid, in the low acceleration detection unit of spy, under the state that low acceleration detection unit or high acceleration probe unit are failure to actuate, can prevent main rope 5 with the shaking resonance of building 1 so that the phenomenon that rope vibrations increases.

Below, the action of each control setup 8 when using the 1st rope vibrations detecting unit 8b is described.The diagram of circuit of the action of each control setup 8 when Fig. 7 is expression use the 1st rope vibrations detecting unit 8b.In Fig. 7, at first, each control setup 8 is controlled the running of car 6 according to common running, and is confirmed whether to receive vibration detecting information from sensor unit 2, and car 6 is remained in operation according to common running until receive vibration detecting information (step S1).After receiving vibration detecting information from sensor unit 2, each control setup 8 is with the building acceleration/accel a and the 1st acceleration levels a that comprise in the vibration detecting information ₁With the 2nd acceleration levels a ₂Compare (step S2), confirm whether building acceleration/accel a surpasses the 2nd acceleration levels a ₂(step S3).Surpass the 2nd acceleration levels a at building acceleration/accel a ₂The time, each control setup 8 makes car 6 carry out running (step S4) according to controlled operation, makes car 6 move to nearest floor, makes car 6 open door, car 6 is stopped, the release of each control setup 8.

On the other hand, do not surpass the 2nd acceleration levels a at building acceleration/accel a ₂The time, each control setup 8 confirms whether building acceleration/accel a surpasses the 1st acceleration levels a ₁(step S5).Surpass the 1st acceleration levels a at building acceleration/accel a ₁The time, 8 pairs of building acceleration/accels of each control setup a surpasses the 1st acceleration levels a ₁Number of times count (step S6).And each control setup 8 confirms that building acceleration/accel a is at the 1st Looking Out Time t ₁Interior the 1st acceleration levels a that surpasses ₁Number of times whether repeatedly (step S7).At this moment, if building acceleration/accel a surpasses the 1st acceleration levels a ₁Number of times be repeatedly, each control setup 8 makes car 6 carry out running (step S4) according to controlled operation, make car 6 move to nearest floor, make car 6 open door, through after the schedule time car 6 is closed the door, the running of car 6 is stopped, the release of each control setup 8.And, do not surpass the 1st acceleration levels a at building acceleration/accel a ₁The time (the "No" direction of step S5) or building acceleration/accel a surpass the 1st acceleration levels a ₁Number of times when being a time (the no direction of step S7), each control setup 8 makes car 6 remain in operation according to common running, and standby is until receive vibration detecting information from sensor unit 2.

At this, during the controlled operation of the execution car 6 in Fig. 6 (during step S4), when making car 6 open the door, close behind the door at nearest floor, stage before the running that makes car 6 stops, the position that each control setup 8 is confirmed cars 6 is the arbitrary position among resonant position D1～D4 whether, when in the position of car 6 being the arbitrary position among resonant position D1～D4, also can make car 6 move to retreating position E.During this situation, as being used for determining the 1st acceleration levels a ₁The longest standing time t ₀, can consider that the passenger goes out the needed time of elevator after car 6 arrives nearest floor.Thus, can prevent after the broadcast of elevator under car 6 interior outputs (driving the passenger out of moves rear), in the large situation of vibration (amplitude) change of main rope 5, can not carry out the situation of keeping out of the way running.That is, before the vibration of main rope 5 became greatly, behind the elevator, each control setup 8 can be carried out the running of keeping out of the way of car 6 under each control setup 8 passenger in making car 6.

And, also can set the 0th acceleration levels a lower than the 1st acceleration levels ₀, surpass the 0th acceleration levels and when the 1st acceleration levels is following, about the running of car 6, its gait of march be lower than usually at building acceleration/accel a, and continue usually running.At this, as the 0th acceleration levels a ₀Concrete establishing method, can be made as the α in the above-mentioned formula (1) less than the 1st acceleration levels a ₁The value of α.During this situation, in the scope of the hooking that does not produce main rope 5, although produce the vibration of smaller main rope 5, but because the gait of march of car 6 is lower than usually, so when the vibration owing to main rope 5 of advancing of car 6 has problems, advancing of car 6 stopped or carrying out controlled operation, can not reduce terrifically the operating efficiency of elevator, and guarantee safety.

Below, illustrate that the 2nd rope vibrations detecting unit 8c detects the principle of rope vibrations.Fig. 8 is for the instruction diagram that shakes that the building 1 that causes because of phugoid is described.Fig. 9 is the diagram of curves that is illustrated in relation when producing the shaking of the building 1 that causes because of phugoid, building displacement z and rope amplitude V and time t.In addition, the longitudinal axis among Fig. 9 represents building displacement z and rope amplitude V, and the transverse axis among Fig. 9 represents time t.In Fig. 8, shaking of the building 1 of the phugoid that causes because of earthquake (long period seismic oscillation) and/or high wind is shaking under the eigentone of building 1.And the increase and decrease amount of the amplitude that shakes of building 1 is compared with the cycle that building 1 shakes very lentamente and is changed.Therefore, the vibration of supposing building 1 is the pure oscillation of fixed amplitude, obtains the rope amplitude (size of the vibration of the horizontal direction of main rope 5) that produces because of shaking of building 1.At this, can think that the vibration of main rope 5 is not have the vibration of the string of decay, so rope amplitude V can utilize the vibration equation formula of following formula (2) to represent.

At this, these building eigentones ω, rope eigentone ω ₀, the tension force T ' of length, main rope 5 of main rope 5 and main rope 5 linear density ρ pre-stored in the 8d of Parameter storage section as the 2nd parameter (specification information of main rope 5).

In above-mentioned formula (2), if rope eigentone ω ₀ω is consistent with the building eigentone, then rope amplitude V and building shake resonance, and increase along with the time according to shown in Figure 9.The intrinsic curve Y of the rope amplitude V of this moment can utilize following formula (4) expression as the function of time t.

[formula 4]

$Y\left(t\right)=\frac{1}{2}z{\mathrm{\&omega;}}_{0}t\&CenterDot;\&CenterDot;\&CenterDot;\left(4\right)$ Formula

Wherein, building displacement z can be expressed as the displacement A of the upper end of the main rope 5 among Fig. 8 shown in following formula (5) ₁Displacement A with the lower end of main rope 5 ₂Aviation value.

[formula 5]

$z=\frac{1}{2}(A_1+A_2)\&CenterDot;\&CenterDot;\&CenterDot;\left(5\right)$ Formula

And, the displacement A of the upper end of main rope 5 ₁Displacement A with the lower end of main rope 5 ₂Can utilize following formula (6) to obtain.

[formula 6]

A _i=c _iA (i=1,2) ... (6) formula

Wherein, A represents building displacement information (for example building amplitude at machine room 1b place).c _jBe when building 1 shakes with an eigentone, the terminal position place of main rope 5 is to the value of the weighting of the shape of building 1, can calculate in advance or measure to obtain, and be contained in the 2nd parameter.

At this, above-mentioned formula (4) is illustrated in the evaluation number of the rope amplitude V that obtains when building displacement z is the pure oscillation of fixed amplitude.Figure 10 represents intrinsic curve and the rope amplitude V of the building displacement z of this moment.Figure 10 is the diagram of curves of the relation of the intrinsic curve of expression building displacement z and rope amplitude V and time t.In addition, the longitudinal axis among Figure 10 represents that dimension is 1 building displacement z and rope amplitude V, and the transverse axis among Figure 10 represents time t.And building displacement z represents the sine waveform of fixed amplitude (being normalized to 1).At this moment, time t is 1, and rope amplitude V is 1.

But the amplitude that shakes of building 1 changed along with the time in reality, so need to consider the change of building displacement z.Figure 11 represent building displacement z along with the time example in when variation.Figure 11 is the diagram of curves of expression building amplitude relation during according to a plurality of increase and decrease pattern time to time change, building displacement z and rope amplitude V and time t.In addition, the longitudinal axis among Figure 11 represents building displacement z and rope amplitude V, and the transverse axis among Figure 11 represents time t.And, (fixedly increase pattern) when Figure 11 shows respectively building displacement z and increases gradually, (fixedly minimizing pattern) when building displacement z reduces gradually, (midway reduce pattern) when building displacement z reduces midway and building displacement z example of (increasing pattern midway) when increasing midway.

In these examples, although the intrinsic curve of building displacement z differs from one another, be 1 o'clock at time t, rope amplitude V is that identical value is 1.At this moment, give following condition for the intrinsic curve of building displacement z, namely when from 0 to 1 couple of time t carried out time integral, value all was 1 (with reference to the oblique line part of Figure 11).Therefore, according to the result who time t from 0 to 1 is carried out time integral, if use the integrated value of building displacement z, then in when change, also can use above-mentioned formula (4) to estimate rope amplitude V along with the time in the building displacement.Therefore, carry out integration and divided by integration time, obtain the mean amplitude of tide z of the building displacement z in integration time by the absolute value to building displacement z _m(t), then obtain following formula (7).

[formula 7]

$z_m\left(t\right)=\frac{\mathrm{\&pi;}}{2}{\&Integral;}_0^t\left|z\right|\mathrm{d\&tau;}/t\&CenterDot;\&CenterDot;\&CenterDot;\left(7\right)$ Formula

By with the mean amplitude of tide z in the formula (7) _mBe updated to the building displacement z of above-mentioned formula (4), the bounds evaluation of the general rope amplitude when the building amplitude changes because of shaking of building 1 is shown in following formula (8).

[formula 8]

$Y\left(t\right)=\frac{1}{2}{z}_m\left(t\right){\mathrm{\&omega;}}_{0}t=\frac{{\mathrm{\&pi;\&omega;}}_0}{4}{\&Integral;}_0^t\left|z\left(\mathrm{\&tau;}\right)\right|\mathrm{d\&tau;}\&CenterDot;\&CenterDot;\&CenterDot;\left(8\right)$ Formula

Wherein, in above-mentioned formula (7), use building displacement z (t), but also can use building acceleration/accel a (t).During this situation, the increase and decrease amount of building amplitude is compared the cycle that building shakes and is slowly changed, so building acceleration/accel a (t) can utilize following formula (9) expression.

[formula 9]

A (t) ≈ A (t) ω ₀ ²(9) formula

Thus, use above-mentioned formula (5) and formula (6) that above-mentioned formula (7) is carried out conversion, obtain following formula (10).

[formula 10]

$z_m\left(t\right)=\frac{\mathrm{\&pi;}(c_1+c_2)}{{{4\mathrm{\&omega;}}_0}^2}{\&Integral;}_0^t\left|a\left(\mathrm{\&tau;}\right)\right|\mathrm{d\&tau;}/t\&CenterDot;\&CenterDot;\&CenterDot;\left(10\right)$ Formula

By this formula (10) is updated in the above-mentioned formula (4), the bounds evaluation of the rope amplitude when using building acceleration/accel a (t) is shown in following formula (11).

[formula 11]

$Y\left(t\right)=\frac{\mathrm{\&pi;}(c_1+c_2)}{{8\mathrm{\&omega;}}_0}{\&Integral;}_0^t\left|a\left(\mathrm{\&tau;}\right)\right|\mathrm{d\&tau;}\&CenterDot;\&CenterDot;\&CenterDot;\left(11\right)$ Formula

As mentioned above, use formula (8) or formula (11) can be obtained rope amplitude V.By using the rope amplitude V that obtains like this, can utilize the structure of the 2nd rope vibrations detecting unit 2c among Fig. 2 to differentiate the controlled operation that to carry out car 6.

And, when the differentiation that the 2nd rope vibrations detecting unit 8c is calculated for the execution of carrying out controlled operation differentiates is made as the estimated valve Y (t) of rope amplitude of above-mentioned formula (11) with grade point Lv (t), obtain following formula (12).

[formula 12]

$L_v\left(t\right)=Y\left(t\right)=\frac{\mathrm{\&pi;}(c_1+c_2)}{{8\mathrm{\&omega;}}_0}{\&Integral;}_0^t\left|a\left(\mathrm{\&tau;}\right)\right|\mathrm{d\&tau;}=K\left(x\right){\&Integral;}_0^t\left|a\left(\mathrm{\&tau;}\right)\right|\mathrm{d\&tau;}\&CenterDot;\&CenterDot;\&CenterDot;\left(12\right)$ Formula

Wherein, K (x) expression comprises rope eigentone ω ₀At the interior coefficient entry definite according to car position x.For example, in Fig. 8, c ₂It is the value that changes according to car position x.In addition, consider the resonance condition of main rope 5 and building 1 herein, rope eigentone ω ₀ω equates with the building eigentone.

At this, illustrate that the 2nd rope vibrations detecting unit 8c calculates (derivation) and differentiates the step of using grade point Lv (t).Figure 12 is the instruction diagram of using the calculation procedure of grade point Lv (t) for the differentiation that explanation is undertaken by the 2nd rope vibrations detecting unit 8c.At first, the 2nd rope vibrations detecting unit 8c receives building acceleration/accel (acceleration signal) a (t), calculates the absolute value of this building acceleration/accel a (t) | a (t) | and, carry out the time integral of this computing value ∫ dt.Then, the 2nd rope vibrations detecting unit 8c according to be stored among the 8d of Parameter storage section building eigentone ω and from the car position x of car position monitoring unit 8f, calculating is based on the coefficient entry K (x) of car position x, according to this coefficient entry K (x) with carried out the acceleration signal ∫ of time integral | a (t) | dt, computational discrimination is with grade point Lv (t).

On the other hand, the pre-stored building acceleration/accel that has conduct to carry out the benchmark of controlled operation is benchmark acceleration/accel a in the 2nd parameter of the 8d of Parameter storage section ₃, the 0th～the 3rd grade allows amplitude L ₀～L ₃, corresponding the 0th grade allows amplitude L ₀The 2nd Looking Out Time t ₂, and the recovery that automatically recovers differentiate time t ₃These the 0th～the 3rd grades allow amplitude L ₀～L ₃Be and differentiate the value that compares usefulness with grade point Lv (t), be used for differentiation and could carry out controlled operation.The the 0th～the 3rd grade allows amplitude L ₀～L ₃The pass be L ₀＜L ₁＜L ₂＜L ₃

And building acceleration/accel a and the 0th grade allow amplitude L ₀Relation according to above-mentioned formula (3), the formula (13) below roughly utilizing is obtained.

And corresponding the 0th grade allows amplitude L ₀The 2nd Looking Out Time t ₂Be t ₂=4 ω ₀L ₀/ a ₀Wherein, for example at L ₀=20mm, ω ₀=1rad/s, a ₃During=0.5gal, to the 2nd Looking Out Time t ₂Set 16sec.And, for example the 1st grade is allowed amplitude L ₁Set 50mm, the 2nd grade is allowed amplitude L ₂Set 100mm, the 3rd grade is allowed amplitude L ₃Setting the minimum amplitude amount that allows is 500mm (being the shortest distance of equipment in rope and the hoistway).

At this, controlled operation mode selection part 8g is in the time could carrying out controlled operation according to the contents processing differentiation of the 2nd rope vibrations test section 8c, contents processing according to the 2nd rope vibrations test section 8c, select monitoring mode, the pattern of going slowly, regulatory model, keep out of the way the arbitrary tupe in discrimination model, back off mode and the automatically recovery pattern, send for the instruction that car 6 is carried out based on the running of selected tupe to master control part 8a (being device for controlled operation 8).Said monitoring mode refers to surpass benchmark acceleration/accel a at building acceleration/accel a ₃The time tupe carried out by device for controlled operation 8, be the tupe that changes the new field of technical activity of the pattern of going slowly over to.The said pattern of going slowly refers to when the execution monitoring pattern, is beginning to play from monitoring mode through the 2nd Looking Out Time t ₂Before, differentiating with grade point Lv (t) above the 0th grade permission amplitude L ₀The time, by the tupe of device for controlled operation 8 execution.And each control setup 8 remains in operation car 6 and the gait of march when making the gait of march of car 6 be lower than common running when pattern is gone slowly in execution.

Said regulatory model refers to when pattern is gone slowly in execution, plays through the 2nd Looking Out Time t when pattern is gone slowly in execution certainly ₂Before, differentiating with grade point Lv (t) above the 1st grade permission amplitude L ₁The time, by the tupe of device for controlled operation 8 execution.Each control setup 8 makes car 6 move to nearest floor when carrying out regulatory model, after car arrives nearest floor, makes car 6 open door and the lower elevator broadcast of output, then makes car 6 close the door (driving action out of).The said discrimination model of keeping out of the way refers to when car 6 rests against resonant position D1～D4, and device for controlled operation 8 is confirmed to differentiate and whether surpassed the 2nd grade with grade point Lv (t) and allow amplitude L ₂Tupe.Each control setup 8 is being differentiated with grade point Lv (t) above the 2nd grade permission amplitude L when discrimination model is kept out of the way in execution ₂The time, make the running of car 6 stop at this stop position (recently floor).On the other hand, each control setup 8 is being differentiated with grade point Lv (t) not above the 2nd grade permission amplitude L when discrimination model is kept out of the way in execution ₂The time, can infer that then the vibration of main rope 5 can not increase, and carries out thus back off mode if car 6 moves towards the direction away from resonant position D1～D4.

Said back off mode refers to tupe from resonant position D1～D4 to retreating position E that car 6 is moved by each control setup 8 from.Each control setup 8 monitors to differentiate with grade point Lv (t) whether allow amplitude L above the 3rd grade when carrying out back off mode ₃, until car 6 arrives retreating position E, differentiating with grade point Lv (t) above the 3rd grade permission amplitude L ₃The time, the running that makes car 6 is emergent stopping on the spot.(that is, in the general elevator that is set with the zone of walking rapidly, refer to that emergent stopping when respond with the high acceleration probe unit moves identical contents processing.)

At this, differentiating with grade point Lv (t) above the 3rd grade permission amplitude L ₃And in the situation of car 6 emergent stoppings, differentiate when perhaps being resonant position D1～D4 in the position of car 6 and surpass the 2nd grade with grade point Lv (t) and allow amplitude L ₂And in the situation that the running of car 6 stops, manually resetting after the maintenance of having accepted the operating personnel, each control setup 8 makes the running of car 6 revert to common running thus.

On the other hand, said automatic recovery pattern refers to differentiating with grade point Lv (t) not above the 2nd grade permission amplitude L ₂Allow amplitude L with the 3rd grade ₃The time, when car 6 rests against retreating position E or nearest floor, whether can make car 6 revert to the tupe of common running by device for controlled operation 8 differentiations.And time t is differentiated in the recovery in the said automatic recovery pattern ₃, refer to from the moment of shaking convergence of building 1, to being equivalent to the 3rd grade permission amplitude L ₃Rope amplitude δ ₁(=L ₃) decay to and be equivalent to the 1st grade and allow amplitude L ₁Rope amplitude δ ₂(=L ₁) time carry out instrumentation, if make the running standby of car 6 until through this time, the vibration that then can be estimated as rope is calmed down.Thus, rest against nearest floor or retreating position E, building acceleration/accel a are lower than benchmark acceleration/accel a at car 6 ₃Stage, each control setup 8 makes timer action, is differentiating time t through over recovery ₃After, the running of car 6 is recovered automatically.

At this, counting down to through over recovery differentiation time t from the beginning timer ₃During in, surpass benchmark acceleration/accel a at building acceleration/accel a ₃The time, will count resets also counts again again.Wherein, recover differentiation time t ₃(fall time of rope amplitude) utilizes following formula (14) to represent.

[formula 14]

${\mathrm{<figure-callout\; id="3"\; label="t"\; filenames="H2007800525864E00011.png,H2007800525864E00081.png"\; state="\{\{state\}\}">t</figure-callout>}}_3=\frac{1}{{\mathrm{\&zeta;\&omega;}}_0}\ln \left(\frac{{\mathrm{\&delta;}}_1}{{\mathrm{\&delta;}}_2}\right)\&CenterDot;\&CenterDot;\&CenterDot;\left(14\right)$ Formula

In above-mentioned formula (14), for example at δ ₁=500mm, δ ₂Differentiation time t during ω=1rad/s, is recovered in=50mm, ζ=0.005 ₃=460sec (about 8 minutes).

In addition, differentiating with grade point Lv (t) above the 2nd grade permission amplitude L ₂Allow amplitude L with the 3rd grade ₃The time, also can stop at car 6/emergent stopping differentiates time t by over recovery ₃After, the automatic maintenance running that each control setup 8 is carried out cars 6 (for example makes car 6 from the bottom top layer of going slowly, whether diagnosis can turn round usually, or measure car 6 at the drive manner of the stop precision of each floor), if it is no problem to be judged to be the running of car 6 under usually turning round, then carry out automatically and reset, make the running of car 6 revert to common running.

Below, the action of each control setup 8 when using the 2nd rope vibrations detecting unit 8c is described.The diagram of circuit of the action of each control setup 8 when Figure 13 is expression use the 2nd rope vibrations detecting unit 8c.In Figure 13, at first, each control setup 8 makes car 6 turn round according to common running, and is confirmed whether to receive vibration detecting information (step S11) from sensor unit 2, car 6 is turned round, until receive vibration detecting information according to common running.And each control setup 8 is reset timer (step S12) when receiving vibration detecting information from sensor unit 2, confirms whether the building acceleration/accel a that comprises in the vibration detecting information surpasses benchmark acceleration/accel a ₃(for example 0.5gal) (step S13).

Do not surpass benchmark acceleration/accel a at building acceleration/accel a ₃The time, each control setup 8 stops timer, makes car 6 proceed running according to common running, and is confirmed whether to receive vibration detecting information from sensor unit 2.On the other hand, surpass benchmark acceleration/accel a at building acceleration/accel a ₃The time, each control setup 8 starting timer 8j of section (carrying out the timer starting), execution monitoring pattern (step S14).And each control setup 8 calculates the differentiation grade point Lv (t) (step S15) of this moment, and confirms whether this differentiation surpasses the 0th grade with grade point Lv (t) and allow amplitude L ₀, until the timer gate time surpasses the 2nd Looking Out Time t ₂(step S16, S17).Surpassing the 2nd Looking Out Time t by the end of the timer gate time ₂Till, differentiating with grade point Lv (t) does not all have the 0th grade of surpassing to allow amplitude L ₀The time, each control setup 8 makes timer stop (step S18), makes car 6 proceed running according to common running, and is confirmed whether to receive vibration detecting information from sensor unit 2.

And, differentiating with grade point Lv (t) above the 0th grade permission amplitude L ₀The time, each control setup 8 switches to the running of car 6 and monitors running from common running, make its execution pattern (step S19) of going slowly.And each control setup 8 confirms to differentiate with grade point Lv (t) whether surpass the 1st grade permission amplitude L ₁, until through the schedule time (the 2nd Looking Out Time t ₂) (step S20, S21).At this moment, do not surpass the 1st grade permission amplitude L if differentiate with grade point Lv (t) ₁, then each control setup 8 is carried out automatically and is reset, and makes the running of car 6 revert to common running (step S21), makes car 6 proceed running according to common running, until receive next vibration detecting information.

On the other hand, differentiating with grade point Lv (t) above the 1st grade permission amplitude L ₁The time, each control setup 8 becomes regulatory model (step S23) to the tupe of controlled operation from monitoring mode, confirms car 6 whether advance (step S24).At this moment, if car 6 is being advanced, then each control setup 8 makes car 6 rest in nearest floor (step S25).When making car 6 rest in nearest floor or car 6 when not advancing, make car 6 open door, passenger's action is driven in elevator broadcast under the car 6 interior outputs out of, and car 6 is closed the door, and carries out and keeps out of the way discrimination model (step S26).

Then, each control setup 8 is confirmed the position of cars 6, and the position of confirming car 6 is the resonant position D1～D4 (step S27) of various ropes whether.At this moment, when in the position of car 6 not being the resonant position D1～D4 of various ropes, each control setup 8 is carried out automatic recovery pattern, after the over recovery differentiation time, implement automatically to reset, make the running of car 6 revert to common running (step S28), make car 6 proceed running according to common running, until receive next vibration detecting information.On the other hand, when in the position of car 6 being the resonant position D1～D6 of various ropes, each control setup 8 is relatively differentiated with grade point Lv (t) and the 2nd grade permission amplitude L ₂, confirm to differentiate with grade point Lv (t) whether surpass the 2nd grade permission amplitude L ₂(step S29).Differentiating with grade point Lv (t) above the 2nd grade permission amplitude L ₂The time, each control setup 8 directly makes car 6 stop, and in the maintenance of accepting the operating personnel with after manually resetting, makes the running of car 6 revert to common running (step S30), make car 6 proceed running according to common running, until receive next vibration detecting information.

And, differentiating with grade point Lv (t) not above the 2nd grade permission amplitude L ₂The time, each control setup 8 is carried out back off mode, begins to make car 6 to retreating position E running (step S31).At this moment, each control setup 8 confirms to differentiate with grade point Lv (t) whether surpass the 3rd grade permission amplitude L ₃(step S32).If differentiate with grade point Lv (t) and do not surpass the 3rd grade permission amplitude L ₃Then each control setup 8 is carried out automatic recovery pattern, implement automatically replacement after the over recovery differentiation time, makes the running of car 6 revert to common running (step S33), make car 6 proceed running according to common running, until receive next vibration detecting information.On the other hand, surpass the 3rd grade permission amplitude L if differentiate with grade point Lv (t) ₃Then each control setup 8 makes on the spot emergent stopping of car 6, in the maintenance of accepting the operating personnel with after manually resetting, makes the running of car 6 revert to common running (step S34), make car 6 proceed running according to common running, until receive next vibration detecting information.

At this, at least either party, pattern select switch 8e and the controlled operation mode selection part 8g among the 1st rope vibrations detecting unit 8b in each control setup 8 and the 2nd rope vibrations detecting unit 8c is configured for differentiating the controlled operation that could carry out controlled operation and carries out judegment part.That is, controlled operation execution judegment part is assemblied in respectively in each control setup 8.And two each control setups 8 are controlled respectively the running (operation of elevator) of corresponding car 6 independently of one another according to common running or controlled operation.In addition, the information of setting in each control setup 8 8d of Parameter storage section separately is different because of the specification of elevator, when receiving identical vibration detecting information from sensor unit 2, each control setup 8 also uses respectively the 1st rope vibrations detecting unit 8b or the 2nd rope vibrations detecting unit 8c independently to calculate rope amplitude (size of the vibration of link), and the execution of the line pipe system of going forward side by side running is differentiated.Thus, when each control setup in two each control setups 8 was carried out the controlled operation of car 6, another each control setup 8 made car 6 remain in operation according to common running.

And each control setup 8 can be made of the computing machine (not shown) with arithmetic processing section (CPU), storage part (ROM, RAM and hard disk etc.) and signal input and output section.In the storage part of the computing machine of each control setup 8, store for the function that realizes the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c, the 8d of Parameter storage section, car position monitoring unit 8f, be the program of Fig. 7 and action shown in Figure 13.

In the controlled operation system of above-mentioned elevator, two each control setups 8 are that controlled operation is carried out judegment part according to the vibration detecting information from a sensor unit 2, the independent rope amplitude (size of rope vibrations) that calculates, according to the rope amplitude that calculates, independent differentiation could be carried out the controlled operation of each car 6, so can switch to controlled operation to the running of the car 6 in a plurality of elevators from common running independently, can improve the discrimination precision the when running of car 6 switched to controlled operation from common running.

In addition, in embodiment 1, amplitude (size of vibration) differentiation according to main rope 5 could be carried out controlled operation, but amplitude that also can independent detection master rope 5, the amplitude of counterweight rope 7, the amplitude of speed controller rope 10 are differentiated according to various ropes amplitude separately and could be carried out controlled operation.And, also can differentiate according to the amplitude of control cable 9 and could carry out controlled operation.

And, in embodiment 1, can select the output that the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c are selected in a ground by pattern select switch 8e, but also can make the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c cooperation.More specifically, can be the result of the 1st rope vibrations detecting unit 8b the 1st acceleration levels a shown in the formula (1) ₁Benchmark acceleration/accel a as the 2nd rope vibrations detecting unit 8c ₃Thus, can be to benchmark acceleration/accel a ₃Provide basis of design, simultaneously the benchmark acceleration/accel a of the 2nd rope vibrations detecting unit 8c ₃Be set as variable parameter.

In addition, in embodiment 1, can select the output that the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c are selected in a ground by pattern select switch 8e, replace pattern select switch 8e but the AND circuit also can be set, controlled operation mode selection part 8g only differentiates when both output is consistent could carry out controlled operation.Thus, redundant by making the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c, can improve the discrimination precision when carrying out controlled operation.

In addition, more than use the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c, but also can omit the either party among the 1st rope vibrations detecting unit 8b and the 2nd rope vibrations detecting unit 8c.During this situation, do not need pattern select switch 8e yet.

In addition, also can utilize the operation computing machine that can be connected with control setup 8, suitably change is stored in the setting of the various parameters (the 1st and the 2nd parameter) among the 8d of Parameter storage section.Thus, can at random set/adjust the detection level of the rope vibrations corresponding with environment is set.
