Abstract

A system for controlling an elevator in a strong wind, the system performing meticulous operation of the elevator without uniformly stopping elevator operation even if a building is swayed by a strong wind. A displacement meter (1) is placed at a predetermined portion of the building and detects the amount of displacement of the building when it is swayed by a strong wind. A strong-wind control device (2) inputs a displacement amount detection signal from the displacement meter (1). When the amount of displacement is greater than a predetermined value, the strong-wind control device (2) determines the level of degree of risk, which level is previously set with regard to building sway by a strong wind, and outputs a control command according to the level of degree of risk to an elevator control device (3). The elevator control device (3) performs elevator control operation based on the control command.

Description

Specification

Elevator strong wind control system

TECHNICAL FIELD [0001] The present invention relates to an elevator strong wind control system that performs elevator operation control in response to shaking of a building caused by strong winds.

Background art

[0002] In an elevator system, since a car moves in a hoistway inside a building, the operation of the elevator is usually hardly affected by wind. However, in the case of high-rise buildings, the strong wind causes considerable vibration in the building itself, and the length of the main rope that suspends the car and the compen- sion rope connected to the car is also considerably long due to the long lifting and lowering stroke. As the building shakes, these long ropes swing greatly in the hoistway.

[0003] Then, various devices installed on the inner wall of the hoistway are damaged by the swinging of these ropes, and there is a risk that a safe operation of the elevator cannot be ensured. Therefore, in the past, in high buildings such as high-rise buildings, if the building shakes more than a certain level due to strong winds, it is determined that it is dangerous to continue the elevator operation, and the elevator Measures were taken to suspend operation (for example, Patent Document 1).

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a configuration diagram of an elevator strong wind control system according to a first embodiment of the present invention. In this figure, the displacement meter 1 is installed at a predetermined location of the building and detects the amount of displacement of the building when the building shakes due to strong winds or earthquakes.

[0019] The strong wind control device 2 receives the displacement amount detection signal from the displacement meter 1, and when the displacement amount exceeds a certain level, the level of the risk level is set in advance for the shaking of the building due to the strong wind. Judgment is made. A control command corresponding to the determined risk level is output to the elevator control device 3. [0020] The elevator control device 3 receives the control command from the strong wind control device 2, and performs the elevator operation control based on the control command.

On the other hand, a car 4 on which a passenger M rides is disposed so as to be movable up and down in the hoistway of the building, and one end side of a rope 5 is attached to the upper part of the car 4. The intermediate part of the rope 5 is wound around the lifting machine 6 and the other end of the rope 5 is attached to the counterweight 7. The elevator control device 3 controls the hoisting machine 6 with respect to the rotational direction and the rotational speed, and controls the raising / lowering movement of the car 4.

[0022] In the present embodiment, the level of danger related to the shaking of the building due to strong wind is the displacement amount force detected by the displacement meter 1, the first level in the case, and the first level in the case where the displacement amount is medium. The level is divided into three levels, the second level and the third level when the displacement is large.

[0023] When the displacement input from the displacement meter 1 exceeds a certain level, the strong wind control device 2 determines which of the above three levels the risk level is. Yes. If the determined level is, for example, the first level, a control command for continuing the operation in such a manner that the car is not stopped at a predetermined dangerous floor for a predetermined time or more is output to the elevator controller 3. Similarly, if the determined level is, for example, the second level, it will be set in advance! A control command will be output to the elevator controller 3 to prohibit the car from stopping on the dangerous floor and continue the operation. It is supposed to be. However, if the determined level is the third level, it will be set in advance! A control command to stop the operation after stopping the car on the safety floor will be output to the elevator controller 3. ing.

[0024] Here, "dangerous floor" refers to a floor where the building cannot be guaranteed to operate safely if the building is greatly shaken by strong winds and the force stops for a predetermined time or longer. What is

Points to floors other than “dangerous floor”. For example, in this embodiment, it is assumed that the building is a high-rise building with 80 floors above ground, and the “dangerous floor” is set in two dangerous sections, 10th floor to 20th floor and 60th floor to 70th floor.

Next, the operation of FIG. 1 will be described based on the flowchart of FIG. The strong wind control device 2 inputs the displacement amount of the building detected by the displacement meter 1 at predetermined intervals (step 1), and this displacement amount is Determine if it is above a certain level (step 2).

[0026] If the amount of displacement is above a certain level, that is, if the building is shaken to a certain extent by strong winds, the strong wind control device 2 calculates the risk level (step 3), and It is determined to which of the three levels the level corresponds (step 4).

[0027] If the determined level is "Level 1," the strong wind control device 2 places the car 4 on the dangerous floors 10 to 20 and 60 to 70 for a predetermined time (for example, about 10 seconds). The control command indicating that the operation should be continued without stopping is output to the elevator controller 3 (step 5). For example, if the car 4 that has increased its power on the first floor arrives at the 10th floor and stops and performs the door opening operation, the door closing operation is performed in a shorter time than in normal operation. Depart to the destination floor of

[0028] The next destination floor in this case is assumed to be a floor other than the 11th to 20th floors. In other words, if the car 4 stops at a certain dangerous floor, it is prohibited to stop continuously at another dangerous floor in the dangerous section to which the stopped dangerous floor belongs. This is because the presence of the car 4 continuously in the same dangerous section increases the risk of falling into a dangerous state. Therefore, it is only after the passenger M, who is riding on the force 4, can go to the 11th to 20th floors that he / she goes to other floors.

However, after car 4 stops on the 10th floor, it is possible to stop next to any of the 60th to 70th floors. This is because the danger zone to which the 60th to 70th floors belong is different from the danger zone to which the 10th to 20th floors belong, and there is time to pass through the safety floor on the way.

[0029] Now, in Step 4, if the determined level is “Level 2”, the strong wind control device 2 has the car 4 on the 10th to 20th floors and the 60th to 70th floors, which are dangerous floors. A control command is issued to the elevator controller 3 to prohibit the stop and continue the operation (step 6). For example, if car 4 is rising from the first floor, the car call or landing call for the 10th to 20th floors, which is a dangerous floor, is invalidated. Therefore, if passenger M wants to go to any of these dangerous floors, he must get out of car 4 on the 9th or 21st floor.

[0030] If the determined level is "level 3" in step 4, the strong wind control device 2 outputs a control command to the elevator controller 3 indicating that the operation should be stopped after the car 4 is stopped on the safety floor, that is, floors other than the 10th floor to the 20th floor and the 60th floor to the 70th floor (Step 7). ). For example, if Force 4 is currently stopping on the 15th floor or rising near the 15th floor, stop operation after Car 4 arrives at the 21st floor and stops. Therefore, the passenger M can get off the car 4 to the safe floor where there is little shaking of the building, and the car 4 and the rope 5 etc. can also be less swung, so that these members during the operation stop Occurrence of a damage accident or the like due to a collision with the inner wall of the hoistway can be avoided.

[0031] Thus, according to the present embodiment, even if a certain amount of shaking occurs in the building due to strong winds, the operation is not immediately stopped, and if the shaking is small, stoppage at the dangerous floor is possible. Continue the operation by shortening the time, and if the shaking is moderate, continue the operation in a state where prohibition on the dangerous floor is prohibited. Since this can be done, service degradation for elevator users can be minimized.

[0032] Even if the building shake is large and the elevator operation has to be stopped, the car is stopped on the safety floor and then stopped so that the passenger can safely avoid the car power. At the same time, it is intended to prevent damages caused by the collision of the car or rope with the inner wall of the hoistway during operation stoppage.

[0033] In the first embodiment, the strong wind control device 2 determines that the danger level is "level 2" in step 4, and the elevator control device 3 controls the control according to this "level 2". When the command (control command according to Step 6) is input, the elevator control device 3 preferably operates the car 4 at a traveling speed that is decelerated compared to the case of normal operation. This is because the impact when the rope 5 or compen- sion rope contacts the hoistway inner wall during traveling can be reduced.

FIG. 3 is a configuration diagram of an elevator strong wind control system according to the second embodiment of the present invention. 3 differs from FIG. 1 in that the monitoring panel 8 is illustrated. This monitoring panel 8 is installed in a management room of a building, for example. As shown in the figure, a mode switching switch 9 having a mode switching lever 9a and a danger level selection lever 10a are provided. With 10 level selection switches!

[0035] The administrator presses the lever 9a of the mode switching switch 9 at three places "automatic", "off", and "manual". By locating in either of these modes, it is possible to select either the automatic mode or the manual mode, or to prevent the shift mode from functioning.

[0036] When the lever 9 & is set to "automatic", the monitoring panel 8 instructs the strong wind control device 2 that strong wind control should be performed based on the automatic mode. In this case, the strong wind control device 2 performs the same operation as that of the first embodiment described above.

[0037] When the lever 9a is set to "OFF", the monitoring panel 8 instructs the strong wind control device 2 to stop the strong wind control control. When lever 9a is set to `` cut '', it is necessary to prevent the strong wind control control function from being activated when the manager determines that the strong wind control is not necessary or during maintenance work by a maintenance worker. There are cases.

When the lever 9a is set to “manual”, the monitoring panel 8 instructs the strong wind control device 2 that the strong wind control should be performed based on the manual mode. In this case, the manager further positions the lever 10a of the level selection switch 10 in any one of the three locations “1”, “2”, and “3”, and based on his / her judgment. You can select the level of risk.

[0039] The lever positions "1", "2", and "3" correspond to "level 1", "level 2", and "level 3" described in the first embodiment. . For example, if the position of the lever 10a is “1”, a command signal indicating that “level 1” has been selected is output from the monitoring panel 8 to the strong wind control device 2. In this case, the strong wind control device 2 performs the control command based on the “level 1” selection command signal sent from the monitoring panel 8 without performing the operation of judging the level of danger based on the displacement amount input from the displacement meter 1. Is output to the elevator control device 3.

[0040] Thus, according to the second embodiment, the manager can freely switch the mode for strong wind control, and when switching to the manual mode, it seems appropriate based on his own judgment. You can select the level of risk that will occur.

FIG. 4 is a configuration diagram of an elevator strong wind control system according to the third embodiment of the present invention. 4 is different from FIG. 3 in that a monitoring panel 8A having a mode display 11 and a level display 12 is provided instead of the monitoring panel 8. FIG. This monitoring panel 8A is shown in Fig. 3. There are also a mode switching switch 9 and a level selection switch 10 which are omitted for convenience of drawing.

[0042] The mode indicator 11 has indicator lights 11a and l ib. Indicator light 11a illuminates when automatic mode is selected (when lever 9a is in the “automatic” position) and indicator light 1 lb is when manual mode is selected. Lights when lever 9a is in “manual” position.

[0043] Further, the level indicator 12 has indicator lights 12a, 12b, and 12c. When the automatic mode is selected, these indicator lights 12a, 12b, and 12c are lit when the strong wind control device 2 determines `` Level 1 '', `` Level 2 '', and `` Level 3 '' respectively. On the other hand, when the manual mode is selected, the administrator selects “Level 1”, “Level 2”, and “Level 3” (the lever 10a is “1”, “2” respectively). , When it is positioned at “3”).

[0044] According to the third embodiment, the manager can immediately confirm the currently selected mode and the level of danger level, and can perform elevator operation management more accurately and quickly. it can.

Note that the third embodiment assumes a configuration in which a mode indicator 11 and a level indicator 12 are added to the configuration of the second embodiment (FIG. 3). When applied to the configuration of this embodiment (FIG. 1), only the automatic mode is set, so that only the level indicator 12 may be attached.

FIG. 5 is a configuration diagram of an elevator strong wind control system according to the fourth embodiment of the present invention. Fig. 5 differs from Fig. 1 in that an earthquake sensor 13 and an earthquake control device 14 are added. In other words, the fourth embodiment is designed to cope with a large earthquake during strong wind control. The type of seismic sensor 13 is not particularly limited, but is a measurement seismometer that measures earthquake motion (ground motion), or a speedometer that detects earthquake vibration as velocity 'acceleration' displacement information Even a deviation such as a meter or displacement meter! /.

Next, the operation of FIG. 5 will be described. The seismic control device 14 inputs the sensor signal from the earthquake sensor 13 every predetermined period, and determines whether a large earthquake of a predetermined level or higher has occurred. It has been determined. The discrimination result of the seismic control device 14 is input to the elevator control device 3.

[0048] Then, when the elevator control device 3 inputs a determination result indicating that a large earthquake of a predetermined level or more has occurred from the earthquake control device 14, the content of the control command input from the strong wind control device 2 is determined. Regardless, the car 4 is immediately stopped on the nearest floor, and the door is opened so that the passenger M is evacuated from the force 4.

[0049] For example, now, the elevator control device 3 is controlling the operation based on the control command of the risk level "level 2" from the strong wind control device 2, and the force 4 is above the 15th floor, which is a dangerous floor. If it is ascending, car 4 would normally only be able to stop at a floor higher than the 20th floor.

However, even in this case, when the elevator control device 3 inputs the determination result indicating that a large earthquake has occurred from the seismic control device 14, the elevator control device 3 moves the car to the 16th floor, which is the nearest floor at that time. And evacuate passenger M to the 16th floor. Rather than moving the car 4 from the 15th floor to the 21st floor during a major earthquake, this is because the car 4 is stopped immediately on the 16th floor, even if it is a dangerous floor. However, it is a force that is considered to have little life-threatening risk for passenger M.

[0050] Thus, according to the fourth embodiment, when a large earthquake occurs during strong wind control, there is a greater risk of life to passengers than to deal with strong winds. Priority can be given to dealing with major earthquakes.

FIG. 6 is a configuration diagram of an elevator strong wind control system according to the fifth embodiment of the present invention. FIG. 6 differs from FIG. 1 in that a speaker 15 as a notification means is shown in the car 4, and an elevator operation based on strong wind control is currently performed by an audio output signal from the elevator control device 3. The fact that it is possible to notify passenger M is that

That is, the elevator control device 3 has a voice output unit in which a message to be notified to the elevator user is stored in advance, and a message corresponding to the control command from the strong wind control device 2 is displayed. Audio output is now possible. For example, if passenger M wants to go to the 15th floor, a strong wind control operation with a risk level of “Level 2” will be carried out! As a result, the car 4 does not stop on the 15th floor and passes as it is, so the passenger M becomes confused. However, in this embodiment, in such a case, since the speaker 15 is operated in advance based on strong wind control, a user who wants to go to the 10th to 20th floors gets down on the 9th or 21st floor. Passenger M will not be confused because he will also announce that he should use the stairs.

According to the fifth embodiment, even if a strong wind control operation in a form different from the normal operation is performed and the elevator user is inconvenienced to some extent, the necessary information is notified to the elevator user. Therefore, it is possible to avoid giving anxiety to the elevator users and making the elevator users feel dissatisfied.
