Description

elevator equipment

technical field

The present invention relates to an elevator device that performs controlled operation when a building shakes due to an earthquake or strong wind.

Background technique

When an earthquake occurs, the faster P-wave (longitudinal wave) and the slower-propagating S (shear wave) that exhibit the main motion of the earthquake propagate from the source to the building, respectively. As a prior art, for example, the following non-patent document 1 discloses a method of classifying the acceleration level of the S wave in the horizontal direction detected by the building shaking device into thresholds consisting of an extremely low level, a low level, and a high level. Level, and use it to control the operation of elevators during earthquakes. Before the shaking of the building due to the main motion of the S wave becomes large, the arrival of an earthquake can be detected several seconds earlier than the S wave by detecting an extremely low level of acceleration in the horizontal direction, or by performing P waves in the lower part of the building The initial micro-motion detection makes the elevator pause, so as to control the operation.

In addition, long-period earthquakes are likely to occur in plain areas with accumulation layers due to the influence of earthquakes with far-away sources. When long-period earthquakes or strong winds occur, although the shaking acceleration of buildings is small, the upper part of the buildings will generate Shaking, so the main sling of the elevator, the governor rope, the cables for power supply to the elevator car, and the cables for signal communication (hereinafter referred to as "long-scale components") are prone to sloshing, resulting in interference with other equipment. Contact can cause equipment damage. Hereinafter, the shaking of this kind of building is simply referred to as "building shaking", and the shaking and vibration of long-scale components caused by building shaking are called "long-scale component shaking", and when expressing the degree of these shaking, " Shake amount of building" and "shake amount of long-scale components".

The acceleration level of building shaking during long-period earthquakes is low. If the acceleration detection sensitivity of building shaking is increased in order to detect the acceleration of this low level, the elevator may be caused by noise and vibration other than the cause that directly causes long-scale parts shaking. Misoperation, thereby performing unnecessary control operations. Therefore, in order to reduce this kind of misoperation, for example, in the prior art shown in Patent Document 1 and Patent Document 2, a control operation method is disclosed, which detects as close as possible to the shaking state of the long-scale components. Controlling operation is carried out by the state quantity of shaking speed, displacement or the product of speed and displacement.

Patent Document 1: Japanese Patent Laid-Open No. 60-15382 (Claims 1 and 2, FIG. 2 )

Patent Document 2: Japanese Patent Laid-Open No. 60-197576 (Claim 1, FIG. 8 )

Non-Patent Document 1: pp. 94-100 of Part 2 of the 2002 edition of "Explanation of Elevator Technical Standards" edited by the Construction Guidance Section of the Housing Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, the Japan Construction Equipment and Elevator Center, and the Japan Elevator Association.

As shown above, in the prior art, although the control operation is carried out by detecting the state quantity of acceleration, velocity, displacement, or the product of velocity and displacement of the building during an earthquake, these prior art are not based on The state quantities that directly cause long-scale components to shake are used for regulatory operation.

In addition, long-period earthquakes that tend to cause shaking of high-rise buildings are earthquakes that occur during the propagation of earthquakes that are far apart from each other in plains such as the Kanto Plain. The distance is relatively far, reaching 150-200 kilometers, so the P wave is very weak.

As a result, there are problems such as P-wave initial micro-motion control cannot perform its function, and long-scale components will come into contact with the equipment in the elevator passage to cause secondary damage when the elevator is running. If the P wave is increased to avoid this situation, When the wave detection sensitivity is low, there is a problem that the elevator will enter a needless stop state due to a small-scale earthquake in the short distance or noise and vibration unrelated to the earthquake. Moreover, when judging the shaking of long-scale components indirectly based on state quantities such as the speed of building shaking, displacement, or the product of speed and displacement, it is impossible to understand the state of the increase and attenuation of long-scale components one by one. Therefore, there are still problems that cannot make a correct judgment on the following situations: (1) Is it allowed to reduce the rated speed for deceleration operation? (2) Whether to temporarily stop the elevator? (3) Is it possible to make the elevator perform evacuation operation, and move the elevator to a position where the shaking of long-scale components will not increase significantly, that is, a position where the shaking of long-scale components will not resonate with the shaking of the building? Or (4) It is impossible to reasonably determine the release time of the control operation of the elevator according to the attenuation degree of long-scale component shaking.

For example, the degree of increase and attenuation of long-scale component shaking caused by the shaking of buildings in long-period earthquake motions is largely determined by the way and duration of shaking of the building. It is impossible to judge the increase and attenuation degree of long-scale component shaking if the state quantity such as the speed, displacement or the product of velocity and displacement of the object is used, so the following control operation is adopted, that is, when judging the occurrence of long-scale components When shaking, it is expected that the shaking of long-scale components will stop within 3 to 5 minutes, and the elevator will be stopped during this period of time.

Contents of the invention

It is an object of the present invention to provide elevator equipment with high control operation accuracy capable of solving the above-mentioned problems.

In order to achieve the above object, the elevator equipment of the present invention controls the operation of the elevator when an earthquake or strong wind occurs. The vibration amount of parts is calculated, and the vibration control operation of long-scale parts is carried out based on the calculation results.

Moreover, by carrying out the sway control operation of the long-scale components, the elevator is prevented from running in a state where the long-scale components are swaying, thereby avoiding uneasiness to passengers, and avoiding secondary damage caused by contact with equipment in the hoistway when the elevator is running. At the same time, the elevator control operation mode during the earthquake and strong wind is also adopted. The control operation mode is used in combination with the building shaking control operation mode of the elevator in the earthquake corresponding to the acceleration level of the building shaking in the prior art. Describe the operation mode of shaking control for long-scale components.

According to the present invention, it is possible to provide an elevator that detects with high precision long-term vibration of components during earthquakes and strong winds, and performs controlled operation.

Detailed ways

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a structural schematic diagram of an elevator in an embodiment of the present invention. In the elevator system of this embodiment, the elevator car 1 is raised and lowered along a guide rail not shown, and the counterweight 2 is also raised and lowered along a guide rail not shown. Moreover, the elevator car 1 and the counterweight 2 are suspended into a bucket type by the main rope 7 passing through the hoist 4 in the machine room 21 at the top of the hoistway 20 , and are driven by the hoist 4 . Here, the control panel 3 , the governor 6 , and the vibration detector 5 are installed in the machine room 21 , and the rope 8 is wound around the governor 6 . And, viewed from the hoist side, there is provided a balance rope 9 for compensating the weight difference between the main rope 7 on the side of the elevator car 1 and the side of the counterweight 2 . Furthermore, a tail cable 10 for supplying power to the elevator car 1 is also provided. In this way, elongated components such as the main sling 7 , the governor rope 8 , the balance sling 9 , and the tail cable 10 are installed in the hoistway 20 . In addition, a bracket 22 for supporting guide rails and equipment in the elevator passage is also provided in the elevator passage.

The vibration detector 5 for detecting shaking of a building has a function of detecting acceleration in the z direction in addition to a function of detecting acceleration in mutually orthogonal horizontal directions (x, y directions). Among them, the acceleration in the z direction is used to judge the initial micro-movement when the earthquake motion arrives and to judge whether the shaking of the building is caused by the earthquake or the strong wind. Here, the acceleration sensor of the shock detector 5 is composed of a combination of two-axis and z-axis sensors integrated in the x and y directions, or a three-axis acceleration sensor integrated in the x, y, and z directions, or by combining each Axial acceleration sensors are made. In addition, the storage case of the vibration detector 5 has a calculation part 30, and the calculation part 30 has a control operation judgment function, which calculates the amount of shaking of long-scale components according to the acceleration signals in the x and y directions detected by the vibration detector 5. , compare the shaking amount of the long-scale parts with a preset threshold value, and judge whether to carry out elevator control operation in the control panel 3 . Here, the calculation part 30 may also be accommodated in the control panel 3 according to specific circumstances.

In addition, the calculation unit 30 also has a function of performing a building-sway control operation based on the horizontal acceleration of building sway caused by S-waves during an earthquake, which is a conventional building-sway control operation.

And, through the up-and-down vibration detection function of the vibration detector 5, when the vibration in the up-and-down direction is not detected although the long-scale component shakes, it can be judged that the shaking of the long-scale component is caused by strong wind, and the vibration of the long-scale component can be determined. Passengers will be notified of the regulatory situation.

The arithmetic processing performed in the arithmetic unit 30 is set as digital processing for reasons such as processing stability and ease of changing preset parameters, but it can also be set as analog processing.

FIG. 2 is an explanatory diagram showing the configuration of the calculation unit 30 . The computing part 30 has a high pass for removing the gravitational acceleration component caused by the levelness installation error of the shock detector 5 and the DC drift component of the acceleration sensor body from the detection signals in the x, y, and z directions of the shock detector 5. Filter 31 (x direction: 31X, y direction: 31Y, z direction: 31Z) and low-pass filter 32 (x direction: 32X, y direction: 32Y, z direction: 32Z) for removing noise vibration components. And, when it is not necessary to judge the early arrival by the P wave of the earthquake motion, or when it is not necessary to judge whether the shaking of the building is caused by the earthquake or the strong wind, it is not necessary to set the acceleration sensor and the filter 31Z in the z direction , 32Z.

In addition, the calculating part 30 also has shaking combining calculating parts 37, 38, 39 and a shaking judging part 40 which judges whether to carry out the shaking control operation of long-scale parts according to the shaking amount of these combined calculations, and the signal of the shaking judging part 40 passes through the signal line 41 Send to control panel 3. Wherein, the above-mentioned sloshing synthesis calculation part constitutes the sway response calculation parts 34X, 35X, 36X in the x direction and the sway response calculation parts 34Y, 35Y, 36Y in the Y direction, and synthesizes the sway response calculations in the x and y directions of the natural period of shaking of each long-scale component. As a result, the x-direction shake response operation sections 34X, 35X, 36X and the Y-direction shake response operation sections 34Y, 35Y, 36Y use the output signal 33X of the filter 32X and the output signal 33Y of the filter 32Y, for the natural period set in advance For each long-scale component shaking vibration mode among the multiple long-scale component shaking vibration modes composed of Ta, Tb, and Tc, the shaking amount of the long-scale component at each time point is calculated.

In the sway judging part 40, the threshold value is set to a plurality of stages, and according to its level, it is judged to limit the operating speed, to suspend the operation, to recover after the safety inspection of the maintenance personnel, or to judge the attenuation level of the swaying of long-scale components, thereby Elevator control operation against vibration of long-scale components can be released.

Using the output signal 33X of the filter 32X and the output signal 33Y of the filter 32Y in the horizontal direction acceleration synthesis operation part 42, calculate the building shake acceleration on the horizontal direction caused by the S wave during the earthquake, and when the building shakes The judging part 43 judges whether to carry out the control operation of building shaking according to the calculation result, and sends the signal to the control panel 3 through the signal line 44 at the same time. In the embodiment of the building shaking judging part 43, according to the method of Non-Patent Document 1, the building shaking is judged according to the acceleration of building shaking, but as shown in Patent Document 1 and Patent Document 2, the The building sway judging section 43 has a function of judging based on the speed of building sway or the displacement state amount.

In the acceleration detection in the up and down direction, the following method is also adopted, that is, according to the signal after passing through the high-pass filter 31Z for removing the gravitational acceleration component and the low-pass filter 32Z for removing the noise and vibration component, in the up-and-down motion calculation In the part 45, the P wave initial micromotion during an earthquake is detected, and the signal is sent to the building shaking judging part 43.

Generally speaking, the P-wave initial micromotion detection during an earthquake is performed by the P-wave detector 24 installed in the elevator pit 23 of the elevator passage 20 shown in FIG. Therefore, by detecting the initial micromotion by the Z-direction acceleration sensor of the vibration detector 5 installed on the upper part of the building, compared with the detection in the elevator pit 23, the detection accuracy can be further improved. Also, it is also possible to reduce malfunctions caused by traffic noise vibrations that are easily detected in the elevator pit portion.

The control of judging the shaking acceleration of the building based on the signal of the building shaking judging part 43 shown in FIG. 2 is basically the same as the prior art shown in Non-Patent Document 1. The shaking amount of long-scale parts is controlled, so when setting the acceleration threshold of the building shaking judgment part 43, it is not set according to the allowable acceleration level on the structural strength of the elevator, but as the height of the building increases. , and gradually reduce the set value of the acceleration threshold to moderate the damage. However, in the present embodiment, since the shaking control of long-scale parts can be carried out by the shaking judging part 40, when setting the acceleration threshold of the building shaking judging part 43, a high acceleration threshold can be set, that is, it can be set to be the same as The threshold value (about 100-150Gal) suitable for the structure of the elevator and the allowable strength of the mechanism can avoid unnecessary acceleration control when a short-distance small-scale earthquake with few long-period components occurs.

In FIG. 3 , the processing flow of long-scale component shaking calculation based on the output signals 33X and 33Y of the filter 32 in the calculation unit 30 will be described.

34X represents the calculation part for calculating the response in the x direction with the natural period Ta using the output signals 33X and 33Y of the filter 32, 34Y represents the calculation part for the response in the y direction, 35X represents the calculation part for calculating the response in the x direction with the natural period Tb, and 35Y represents y The direction response operation part, 36X represents the operation part for calculating the response in the x direction with the natural period Tc, and 36Y represents the operation part for the response in the y direction. 37 , 38 , and 39 denote a shake synthesizing operation section for synthesizing the shakes in the x and y directions of each of the natural periods, and show examples of computed signal waveforms at the respective locations.

In FIG. 4 , the main sling 7 is taken as an example, and the three-dimensional model diagram when long-scale components shake is used to describe the calculation function and the control operation judgment function of the calculation part 30 .

51 represents the swaying locus on the two-dimensional surface in the horizontal plane 50 in the horizontal plane 50 at the middle position where the amplitude of the main rope 7 swaying three-dimensionally is relatively large, and 34X, 35X, and 36X represent the swaying trajectory for each natural period Ta, Tb, The x-direction shake response calculation part of the long-scale component that calculates the projection component of the shake trajectory 51 toward the X axis of Tc, 34Y, 35Y, and 36Y represent the y-direction shake response of the long-scale component that calculates the projection component toward the Y axis Operation part. As a result, the compositing calculations of the components in the x and y directions in the horizontal plane 50 are performed in the wobbling synthesis calculation units 37 , 38 , and 39 of the long-scale component wobbles of each period.

The shake control based on the shake calculation of long-scale components in this embodiment is illustrated below with an example. The ratios α%, β%, γ%, and δ% of the amount of sway of the elongated components shown in FIG. γ<δ) is used as the threshold value of the sway determination section 40, and an example in which sway control is performed based on the amount of sway of a long-scale component will be described.

In the sway control operation of long-scale components, the sway judging part 40 has a control operation judgment function, that is, the control operation is performed in the following manner: when the sway rate of long-scale components exceeds β%, the deceleration operation or the compulsory operation when approaching the top floor are performed. Call control operation (in the state where the main sling is shaking, if the elevator car travels directly to the highest floor, the elevator car will sometimes produce abnormal vibrations, so a virtual call is generated by running software on the previous floor of the highest floor, so that the elevator Temporary parking operation mode) and other operations, such as the running control operation, when it exceeds γ%, the operation is suspended, when the decay is below β%, the operation control operation is restarted, when the decay is below α%, the control operation is released, when When it exceeds δ%, the elevator is stopped before the inspection in the hoistway is completed.

The following will describe the effect of combining the vibration control of long-scale components shown in the present embodiment and the control of building vibrations in the prior art in the control operation of elevators during earthquakes. By combining long-scale component shaking control and building shaking control, P-wave initial detection control and S-wave initial monitoring control based on the preset P-wave threshold and S-wave threshold are adopted, even if the long-period seismic motion is missed Weak P-wave initial fretting can also be used to control long-scale component shaking through the initial detection of S-wave. Specifically, after the S-wave arrives, the intensity of long-scale component shaking increases approximately within 30 to 60 seconds, so long-scale component shaking control can be carried out in the early stage, and the elevator can be moved to long-scale components that are difficult to reach according to specific conditions. Evacuate to a shaking location. Here, after adopting the S-wave initial control, the situation of temporarily stopping at the nearest floor due to small-scale earthquakes will increase, but after a certain period of time has passed after the S-wave is detected, the building shaking judging part 43 can judge After the acceleration of the S wave, the control based on the shaking acceleration of the building is released, so as long as the long-scale components no longer shake, they can quickly return to normal operation. Specifically, as long as the magnitude of the synthetic calculation value of the acceleration in the horizontal direction after the S wave is detected is below the allowable building shaking intensity of the structure and mechanism of the elevator, after the building shaking control is lifted, due to the The vibration control of long-scale parts can play its role, so it will not affect the expected function of the elevator control operation.

In the above description, the threshold value of the shaking judging part 40 is set as a single scalar, but it is also possible to judge whether the response coordinate values in the x and y directions exceed this region by setting the judging region 52 shown in FIG. 4 .

The following describes the calculation of the shaking response of long-scale components. When long-period earthquakes or strong winds occur, the long-scale components will sway along with the shaking of the building. The periodic components that appear when the building shakes are related to the respective inherent periodic frequency bands contained in the long-period seismic motion and wind motion. It has a certain relationship with its size, and the principal component of the building shaking cycle is still a natural cycle when the upper part of the building shakes the most. Therefore, when the natural period of the long-scale component is close to the primary natural period T ₀ (seconds) of the building, it will resonate with the building's shaking, resulting in an increase in its shaking.

For example, in terms of the position of the elevator car when each long-scale component resonates with the sway of the building, when the position of the elevator car is near the lower floor of the building, the main rope on the side of the elevator car is likely to interfere with the sway of the building. Resonance, and when the elevator car is located in the middle of the building, the governor rope 8 and the balance sling 9 whose tension is smaller than the main sling 7 tend to resonate with the shaking of the building. In this way, the shaking of long parts is affected by the position of the elevator car, but the degree of damage caused by the shaking of long parts is related to the amount of shaking of long parts. Therefore, the control operation of the elevator can be achieved by calculating the shaking amount from the vibration modes of multiple natural periods in a state where the primary natural period of long-scale components is close to the primary natural period of the building.

Here, the first-order natural period of a building generally has a characteristic that its period is related to the magnitude of the shaking of the building, and the period becomes longer as the shaking increases. The primary natural period value of the building when the shaking acceleration of the building is around 30Gal during strong winds or long-period earthquakes is slightly shorter than the natural period of the building when the shaking acceleration is set above 200Gal in the earthquake-resistant design of the building, and the natural period The design value of period can not necessarily give the value of strong wind or long-period seismic motion. Furthermore, the natural period of the building is different in each shaking direction in the short side and the long side direction of the building. For this reason, in order to avoid the fluctuation of the period due to the period amplitude of the short side and long side direction of the building's natural period and the size of the building's shaking, which will bring difficulties to the shaking prediction of long-scale components, the natural period Ta, Multiple long-scale component shaking vibration modes composed of Tb and Tc are used to improve the accuracy of shaking prediction, and the shaking amount of long-scale components is predicted according to the shaking responses of each of the modes, so as to perform control operations. And, according to the response data of the observed earthquake, learn the natural period value of the building, and use the learned natural period to adjust the values of the natural period Ta, Tb, Tc of the vibration mode of long-scale component shaking, so as to Improve the prediction accuracy of lateral sloshing of long-scale components.

Regarding the attenuation characteristics of the shaking vibration system of long-scale components, although the components of long-scale components are slightly different, by using common values that can stably calculate the amount of sloshing of long-scale components, it is possible to ensure real-time calculation of the amount of sloshing Processing performance.

The speed of the digital operation processing of the operation part 30 is set to such a speed that all vibration response calculations are completed within the sampling period (second) of converting the acceleration analog signal into a digital signal, and is set to be able to convert the obtained response value The real-time processing speed at which response calculations are sequentially performed as initial values in the next calculation step. Also, the sampling period (seconds) is related to, for example, the shortest natural period (seconds) among a plurality of preset natural periods, but as long as it is approximately 0.01 to 0.03 seconds, the accuracy of response calculation can be maintained.

According to the above-mentioned structure, it is possible to judge the shaking state of long-scale components caused by shaking of buildings at various points in time, so it can be based on the long-period seismic motion that is likely to occur when an earthquake with a long-distance focal point propagates to a plain area with accumulation layers According to the shaking mode and duration of shaking of the building, the increase and attenuation degree of long-scale component shaking are calculated in sequence, and high-precision elevator control can be carried out on the basis of considering the shaking characteristics of long-scale components during earthquakes or strong winds run.

In the above-mentioned embodiment, the calculation part 30 has the long-scale component shaking control function, but when it is known in advance from the weather forecast that the building will shake due to typhoon or strong monsoon, etc. in a long period of time, in order to avoid To bring uneasiness to passengers, it is also possible to separate the control operation of the elevator from the control range of the shaking judgment part 40, and display the calculation results of the shaking calculation part of the long-scale parts on the elevator monitoring panel in the building equipment monitoring room, etc., thereby The operation mode of the control function for judging the shaking of long-scale components is judged by the elevator monitoring room.

As mentioned above, since the up-and-down movement of the earthquake in the early stage of the earthquake will increase in the building, the detection accuracy will be better when the detection is performed on the upper part of the building compared with the detection in the elevator pit 23. The first acceleration sensor installed on the upper part of the building detects the initial vibration of the earthquake, which is easily affected by the noise and vibration of the machinery and equipment in the building represented by elevator equipment and air-conditioning equipment. Therefore, another second acceleration sensor is installed in other parts of the building that can avoid the dependence on the noise and vibration of the upper part of the building, and the initial vibration value of the earthquake detected by these first and second acceleration sensors is calculated according to the logic sum. By judging whether or not the initial micromotion of the seismic movement has arrived, the initial micromotion can be accurately detected without being affected by noise and vibration. In addition, the P-wave detector 24 provided in the elevator pit 23 may be used as long as dependence on the noise and vibration of the upper part of the building can be avoided.

进行运算的三轴加速度合成运算部分46的信号与建筑物晃动判断部分43的阈值进行比较，能够检测到P波和S波混合的初期微动，并且P波初期微动的主分量为上下运动，但在发生长周期地震时，由于震源地较远，所以也包括水平方向的加速度分量。因此，通过以三轴加速度合成信号判断P波初期微动，则能够提高初期微动的检测精度。When long-scale component shaking control and building shaking control are used at the same time, and the P wave initial detection control and S wave initial monitoring control are performed according to the preset P wave threshold and S wave threshold, when judging the initial slight movement, As shown in Figure 5, the synthesis operation of the acceleration signals in each direction of x, y, and z is used, for example, with

Comparing the signal of the three-axis acceleration synthesis calculation part 46 with the threshold value of the building shaking judgment part 43, it is possible to detect the initial slight movement of the mixture of P wave and S wave, and the main component of the initial slight movement of the P wave is up and down motion. , but when a long-period earthquake occurs, the acceleration component in the horizontal direction is also included because the epicenter is far away. Therefore, the detection accuracy of the initial micromotion can be improved by judging the initial micromotion of the P wave using the triaxial acceleration composite signal.

In the above-mentioned embodiments, the vibration detector 5 is installed in the machine room 21, but the installation location is not particularly limited as long as it is a location where shaking of the building can be detected. In addition, in the above description, the acceleration sensor signal is used in the long-scale part shake calculation, but the speed sensor signal can also be used. In this case, it can be used in the long-scale part shake calculation only by changing the calculation method of the calculation part. .
