The specific embodiment
With reference to the accompanying drawings embodiment is described.
(first embodiment)
Fig. 1 is the figure of the formation of the related elevator of expression first embodiment.Nowadays imagine the situation that in certain building 10, is provided with an elevator 11.

In addition, be provided with car control setup 18 on the top of car 14.Car control setup 18 carries out open and close controlling to car door 19 when car 14 arrives arbitrary using escalator place of using escalator place 21a, 21b, 21c... of each layers.The transmission cable 20 of this car control setup 18 through being known as " lead-in wire (tail cord) " with after the control setup 22 stated be connected.
On the other hand, in the 10a of the Machine Room of building 10, be provided with the control setup 22 that is used to move control elevator 11.In addition, as far as the elevator of inorganic house type, in elevating road 10b, be provided with control setup 22.
This control setup 22 comprises the computing machine that has carried CPU, ROM, RAM etc., carry out towing machine 12 drive controlling etc., control relevant a series of processing with the operation of elevator.In addition; Of the back; This control setup 22 possesses: be used for since earthquake and/or high wind etc. causing under the situation that building 10 shakes, detect the rope that shakes of following this building 10 vibration function and be used for correspondingly car 14 being carried out the function of control operation with this testing result.
In addition, so-called " rope vibrations " is meant and follows the shaking of building 10, rope to vibrate in the horizontal direction.In addition, said here " rope " is meant the rope related with the up-down working phase of car 14, in the example of Fig. 1, except that main rope 13, also comprises compensation rope 17.
At this, near the top of building 10, be provided with the acceleration pick-up that shakes 23 that is used to detect the building 10 that causes owing to earthquake and/or high wind etc.This acceleration pick-up 23 comprises two axle acceleration sensors of the acceleration/accel of the horizontal direction (x direction and y direction) that can detect building, and this detection signal is outputed to control setup 22.
In addition, be connected with at control setup 22 and comprise the for example configuration switch 24 of rotor switch.This configuration switch 24 is set the needed various parameters of detection (Δ t, Δ α, G, Al) that above-mentioned control setup 22 carries out rope vibrations by the service personnel operation.
Fig. 2 is the block diagram that the function of the elevator control device 22 in expression first embodiment constitutes.
As shown in Figure 2, control setup 22 comprises rope vibrations test section 31, time meter 32 and control operation control part 33.
Rope vibrations test section 31 is by keeping watch on the time length that it shakes by each shaking quantity of acceleration pick-up 23 detected buildings 10.And; Rope vibrations test section 31; Based on the functional expression f (α that derives for the analysis result of the vibratory magnitude of rope from 10 the shaking quantity and the time length of building; T), set threshold value, be the above-mentioned threshold value of institute output rope vibrations detection signal when above the shaking quantity of building 10 and time length long-pending for rope vibrations.
Control operation control part 33 makes car 14 stop at nearest floor based on the rope vibrations detection signal from 31 outputs of rope vibrations test section or makes its control run to floor to be kept away.
At this, the functional expression that in rope vibrations detects, uses is described.
When the shaking quantity of building 10 and time length were resolved for the relation of the vibratory magnitude of rope, (α t) set up following functional expression f.
(α-Δα)(t-Δt)≥G ...(1)
α is the shaking quantity of building 10, and t is the time length that building shakes.In addition, Δ t, G, Δ α are the parameter that rope vibrations detects.
Δ t is the minimum duration that building shakes.Shake through in during this section of Δ t time from building takes place, have nothing to do with the size of vibration and do not carry out the detection of rope vibrations.
G is the threshold value that rope vibrations detects, and shakes amassing and setting of time length t with it with respect to the shaking quantity α of building 10.If the shaking quantity α of building 10 shakes the long-pending for more than the threshold value G of time length t with it, the rope vibrations of generation scheduled volume when car 14 stops at rope and shakes the position of resonance with building then.
Threshold value G is corresponding with the rope vibrations amount and set.For example the rope vibrations amount is being made as under the situation of 300mm, when with the shaking quantity α of building 10 and time length t concern pictorialization the time, become inverse proportional figure as shown in figure 3, α and t long-pending is steady state value.
Δ α is the minimum shaking quantity of building.It is meant because building shakes and causes rope resonance, the size of shaking of the building of the force balance of power that rope vibrations increases and rope vibrations convergence.Even the building below the Δ α shakes long-time continuing, rope vibrations can not begin to increase from scheduled volume yet.
Fig. 4 is the figure of the analysis result of expression rope vibrations, has represented the vibratory magnitude of rope is understood the result who analyses for these three grades by " vibration is high ", " vibrating low ", " vibration is special low ".
" vibration is high " is meant the vibrational state that rope might contact with the equipment in the elevating road 10b." vibrate " to be meant the state of rope low with 50～70% the degree vibration of " vibration is high "." vibration is special low " is meant the state that rope begins to vibrate.To these three grades difference setting threshold G, can be " vibration is high ", " vibrating low ", " spy is low in vibration " these three kinds of rope vibrations detection signals through in advance based on the vibratory magnitude of above-mentioned formula (1) output rope.
The work of first embodiment then, is described.
Fig. 5 is the diagram of circuit of the work of treatment that detects of the rope vibrations of the elevator of expression in first embodiment.
At first, as initial setting, service personnel operating and setting switch 24 detects needed various parameter with rope vibrations and preestablishes in the rope vibrations test section 31 of control setup 22 (step S11).
Various parameters are meant above-mentioned minimum duration Δ t, minimum shaking quantity Δ α and threshold value G.In addition, in addition, also comprise and continue Looking Out Time A1.Value in the various parameters of this setting is stored in the not shown storage part that is arranged in the control setup 22, is read by rope vibrations test section 31 in good time.
Above-mentioned continuation Looking Out Time A1 is meant that the building of regarding identical size as shakes the lasting time.That is, as shown in Figure 6, alternatively up and down is repeatedly as sinusoidal waveform for the signal that building shakes.Therefore, temporarily low immediately than Δ α, in order to see the next cycle, during till continuing Looking Out Time A1, also proceeding to keep watch on.
At this, building is owing to earthquake and/or high wind etc. is shaken, and the acceleration signal of the shaking quantity α of expression building 10 is input to from acceleration pick-up 23 the rope vibrations test section 31 of control setup 22 (among the step S12 " being ").
When acceleration pick-up 23 degree of will speed up signals are input into rope vibrations test section 31, starting time meter 32 is kept watch on the time length t (step S13) of the shaking quantity α of this acceleration signal of expression.At this moment, consider that above-mentioned continuation Looking Out Time A1 carries out the supervision of time length t.
In the example of Fig. 6, represented that shaking quantity α is the time length of 1Gal and 3Gal, but in fact promptly carried out the supervision of time length by each shaking quantity of building by each acceleration/accel input, carry out the computing of above-mentioned formula (1).
When the shaking quantity α that obtains building 10 shook time length t with it, rope vibrations test section 31 calculating shaking quantity α shook amassing of time length t and detect rope vibrations (step S14) with it.In detail, also be considered as above-mentioned various parameter and the minimum duration Δ t and the minimum shaking quantity Δ α that set, (a t) carries out the computing of (α-Δ α) (t-Δ t) according to the functional expression f shown in the above-mentioned formula (1).
If the value that obtains as this operation result is (" to be ") among the step S15 more than the pre-set threshold G; Then rope vibrations test section 31 is judged as rope and is in by by the state that vibrates more than the determined scheduled volume of above-mentioned threshold value G, to control operation control part 33 output rope vibrations detection signals (step S16).Thus, in control operation control part 33, towing machine 12 is carried out drive controlling, make car 14 stop at nearest floor and perhaps move it to floor to be kept away.Then, for the sake of security, shake up to building convergence during, stop the operation (step S17) of elevator.
In addition, owing to move the position difference of waiting to keep away floor of destination, rope might resonate, so the set positions that will not resonate in advance is floor to be kept away.
So according to first embodiment, can use the shaking quantity of expression building and the functional expression of the relation of time length to set threshold value for rope vibrations, detect the vibration of rope through using this threshold value, can prevent that useless control from moving.
(second embodiment)
Describe in the face of second embodiment down.
In second embodiment, consider that also car position sets the threshold value of rope vibrations.
Fig. 7 is the block diagram that the function of the elevator control device 22 in expression second embodiment constitutes.In addition, for above-mentioned first embodiment in the identical identical Reference numeral of part mark of the formation of Fig. 2, omit explanation to it.
In second embodiment, in control setup 22, append and be provided with car position test section 34.Car position test section 34 detects the current location of car 14, and this detection signal is outputed to rope vibrations test section 31.
As the inspection method of car position, just like inferior method:, the impulse singla of exporting synchronously from the rotation of this pulse coder and motor is counted, thereby detected through using the pulse coder that for example on the motor drive shaft of towing machine 12, is provided with.
Rope vibrations test section 31 and the threshold value that is correspondingly changed rope vibrations by these car position test section 34 detected car positions output to the rope vibrations detection signal in the control operation control part 33 according to the threshold value after this change.
That is, when long period earthquake and/or high wind, building 10 shakes with a natural frequency easily.For example, with regard to depth of building was the super high rise building more than the 120m, a natural frequency was the scope of 0.1～0.5Hz.With regard to super high rise building, the natural frequency scope of rope is in 0.1～0.5Hz, because building shakes the possibility height that causes rope resonance.
At this, as shown in Figure 8, rope lengths L0 changes because of the stop position of car 14.Shown in following formula (2), correspondingly obtain 1 secondary frequencies with rope lengths L0.When the frequency of shaking when secondary frequencies of rope and building is consistent, cause resonance, the vibration of rope increases.On the contrary, if a secondary frequencies of rope is different with the frequency that building shakes, then rope does not resonate, and the vibration of rope does not increase.
Depth of building: H (m)
Natural period a: T of building (s)=0.025 * H
Building one secondary frequencies: f (Hz)=1/T
The amplitude of building topmost: D (m)
The acceleration/accel of building topmost: α (m/S
2)
α＝D×(2π/T)
2
One secondary frequencies of rope: fi (Hz)
Rope lengths: L0 (m)
The mean tension of rope: T0 (N)
The quality of the average unit length of rope: ρ A (kg/m).
So, because the vibratory magnitude in rope when resonance is correspondingly different with car position, so the preferred threshold value of switching for above-mentioned shaking quantity α shakes amassing of time length t with it for.
Fig. 9 is the diagram of circuit of the work of treatment that detects of the rope vibrations of the elevator of expression in second embodiment.
At first, as initial setting, service personnel operating and setting switch 24 detects needed various parameter with rope vibrations and preestablishes in the rope vibrations test section 31 of control setup 22 (step S21).
Various parameters are meant above-mentioned minimum duration Δ t, minimum shaking quantity Δ α and threshold value G.In addition, in addition, also comprise and continue Looking Out Time A1.About threshold value G, measure rope in advance and shake the vibratory magnitude of resonance because of car position and building, set and the corresponding threshold value of this vibratory magnitude by each car position.Value in the various parameters of this setting is stored in the not shown storage part that is arranged in the control setup 22, is read by rope vibrations test section 31 in good time.
At this, building is owing to earthquake and/or high wind etc. is shaken, and the acceleration signal of the shaking quantity α of expression building 10 is input to from acceleration pick-up 23 the rope vibrations test section 31 of control setup 22 (among the step S22 " being ").
When acceleration pick-up 23 degree of will speed up signals are input into rope vibrations test section 31, starting time meter 32 is kept watch on the time length t (step S23) of the shaking quantity α of this acceleration signal of expression.At this moment, consider that above-mentioned continuation Looking Out Time A1 carries out the supervision of time length t.
When the shaking quantity α that obtains building 10 shook time length t with it, rope vibrations test section 31 calculating shaking quantity α shook amassing of time length t and detect rope vibrations (step S24) with it.In detail, also be considered as above-mentioned various parameter and the minimum duration Δ t and the minimum shaking quantity Δ α that set, (a t) carries out the computing of (α-Δ α) (t-Δ t) according to the functional expression f shown in the above-mentioned formula (1).
At this moment, stop at floor arbitrarily if be made as car 14, then rope vibrations test section 31 from car position detect 34 obtain this stop position (current car position) information (step S25).Then, rope vibrations test section 31 and this car position be switching threshold G (step S26) correspondingly, and the threshold value G after this switching is compared (step S27) with the value that in above-mentioned steps S24, calculates.
Its result; If operation values is threshold value G above (" being ") among the step S27; Then rope vibrations test section 31 is judged as rope and is in by by the state that vibrates more than the determined scheduled volume of above-mentioned threshold value G, to control operation control part 33 output rope vibrations detection signals (step S28).Thus, in control operation control part 33, towing machine 12 is carried out drive controlling, make car 14 stop at nearest floor and perhaps move it to floor to be kept away.Then, for the sake of security, shake up to building convergence during, stop the operation (step S29) of elevator.
Rope maybe be because of moving the further resonance of position of waiting to keep away floor of destination, so the set positions that will not resonate in advance is floor to be kept away.
So according to second embodiment, consider that through appending car position comes setting threshold, can further correctly detect and follow the rope vibrations that building shakes and switch to the control operation.

In such formation, when building 10 shakes owing to earthquake and/or high wind, detect the shaking quantity α of buildings 10 and it is offered arithmetic and logic unit 52 by the acceleration pick-ups in the detector 50 51.Calculating shaking quantity α shakes amassing of time length t and detects rope vibrations with it in arithmetic and logic unit 52.In detail, append the minimum duration Δ t and the minimum shaking quantity Δ α that are considered as above-mentioned various parameter and set, (a t) carries out the computing of (α-Δ α) (t-Δ t) according to the functional expression f shown in the above-mentioned formula (1).
If the value that obtains as this operation result is more than the pre-set threshold G, then export the rope vibrations detection signals to control setup 22 from arithmetic and logic unit 52.
In this case; As shown in Figure 4; If for the vibratory magnitude of rope is understood the result that analyses setting threshold G respectively for these three grades by " vibration is high ", " vibrate low ", " vibration is special low ", can be " vibration is high ", " vibrating low ", " it is low to vibrate the spy " these three kinds of rope vibrations detection signals to the vibratory magnitude of control setup 22 output ropes then based on above-mentioned formula (1).In control setup 22, if be transfused to this rope vibrations detection signal, then operational mode is switched to the control operation, make car 14 stop at nearest floor and perhaps move it to floor to be kept away.
