Abstract

PROBLEM TO BE SOLVED: To provide a controlled operation system for an elevator which reliably determines whether swings of a long-sized body due to long-period tremors of a construction are caused by an earthquake or a strong wind to perform controlled operation in accordance with the causes.SOLUTION: A controlled operation system 1 of an elevator E of the embodiment includes a long-sized body swing sensor 9, an earthquake early warning device 200, a wind velocity sensor 110, and an elevator control board 10. The long-sized body swing sensor 9 decides a swing state of a long-sized body T based on tremor information of a construction 100. The earthquake early warning device 200 sends an earthquake early warning. The wind velocity sensor 110 detects a wind velocity. The elevator control board 10 performs controlled operation in an earthquake in accordance with the swing state of the long-sized body T in receiving the earthquake early warning and performs controlled operation in a strong wind in accordance with the swing state of the long-sized body T when the wind velocity by the wind velocity sensor is equal to or more than a prescribed wind velocity. The opportunities of the controlled operation for maintaining the operation of the elevator are more frequent in the controlled operation in a strong wind than in the controlled operation in an earthquake.

Description

  Embodiments described herein relate generally to an elevator operation control system.

  Buildings, especially high-rise buildings that employ flexible structures, have long-period ground motion, which is long-period vibration caused by earthquakes, even if the epicenter of a relatively large earthquake is far from the building. When the frequency coincides with the frequency, the building is resonated and the amplitude is suddenly amplified, and a long-period shaking in which a relatively large shaking continues for a long time on the upper floor of the building is generated. Even in an elevator installed in a building, long objects such as main ropes swing due to long-period shaking, and contact with or get caught in the hoistway or structures in the hoistway, hindering elevator operation. Therefore, elevator control operation is adopted.

  Here, both long-period vibrations caused by earthquakes and long-period vibrations that occur when the building is shaken by the wind differ only in the input source, and long-period vibrations occur in the building if they match the natural frequency of the building. The long object is resonated.

JP 2008-137800 A

  The present invention has been made in view of the above, and it is possible to reliably determine whether the vibration of a long object due to a long-period vibration of a building is due to an earthquake or a wind, and control operation according to each is performed. An object of the present invention is to provide an elevator control operation system that can be performed.

  The elevator control operation system according to the embodiment includes a long object shake sensor, an earthquake information transmission device, a wind speed sensor, and a control device. The long object shake sensor determines the shake state of the long object that the elevator has based on the shake information of the building where the elevator is installed. The earthquake information transmitter transmits earthquake information. The wind speed sensor detects the wind speed outside the building. The control device controls the operation of the elevator E. When the control device receives the earthquake information, the control device performs an earthquake control operation according to the shake state of the long object determined by the long object shake detector, and if the wind speed by the wind speed sensor is equal to or higher than the predetermined wind speed, Control operation in strong winds according to the state of vibration of the object. The control operation during strong winds is more control operation that maintains the operation of the elevator than the control operation during an earthquake.

FIG. 2 is a block diagram of the elevator control operation system according to the present embodiment. FIG. 3 is an explanatory diagram of an earthquake control operation and a strong wind control operation of the elevator control operation system according to the embodiment. The control operation system 1 of the elevator E includes a long object shake detector 9, an emergency earthquake warning device 200, a wind speed sensor 110, and an elevator control panel 10, and further includes an alarm device 300. The elevator E is composed of a car 2, a main rope 3, a hoisting machine 4, a deflecting sheave 5, a counterweight 6, a compen- sion rope 7, a compensatory 8, a long object shake sensor 9, and an elevator. And a control panel 10. In the present embodiment, the car 2, the counterweight 6, the compensation rope 7, and the compensation sheave 8 are disposed in the hoistway 11. Further, the hoisting machine 4, the deflecting sheave 5, the long object shake sensor 9, and the elevator control panel 10 are disposed in the machine room 12. In addition, although this embodiment demonstrates the elevator E in which the machine room 12 is arrange | positioned at the upper part of the hoistway 11, the elevator E without the machine room 12 may be sufficient.

  The car 2 is for passengers to get on and off. The car 2 is disposed between a pair of car guide rails (not shown), and moves up and down the hoistway 11 by moving up and down along the car guide rails.

  The main rope 3 connects the car 2 and the counterweight 6. In the present embodiment, one end of the main rope 3 is connected to the upper part of the car 2, and the other end is connected to the upper part of the counterweight 6, and is wound around the hoisting machine 4 and the deflecting sheave 5. ing.

  The hoisting machine 4 rotates the main rope 3 to rotate, and raises and lowers the car 2 and the counterweight 6 connected to the main rope 3 in a hoistway 11 like a fishing bottle. The hoisting machine 4 winds up the main rope 3 by the hoisting pulley 42 rotating by the driving force of the motor 41. The hoisting machine 4 is electrically connected to the elevator control panel 10, and drive control is performed by electric power supplied via the elevator control panel 10.

  The deflecting sheave 5 adjusts the fishing width when the main rope 3 is connected to the car 2 and the counterweight 6. The deflecting sheave 5 is set in the vicinity of the hoisting machine 4 in the machine room 12. The main rope 3 located between the hoisting machine 4 and the counterweight 6 is wound around the deflecting sheave 5 in this embodiment.

  The counterweight 6 moves up and down in the hoistway 11 in conjunction with the raising and lowering of the car 2, and causes an unbalance between the car 2 and the hoisting machine 4. The counterweight 6 is disposed between weight guide rails (not shown) and moves up and down along the weight guide rails.

  The compensation rope 7 is suspended from the car 2 and the counterweight 6. The compen- sion rope 7 has one end connected to the car 2 and the other end connected to the counterweight 6. In the present embodiment, the compen- sion rope 7 has one end fixed to the lower part in the vertical direction of the car 2 and the other end fixed to the lower part in the vertical direction of the counterweight 6.

  The compensation sheave 8 is arranged in a pit P provided in the lower part of the hoistway 11, and the compensation rope 7 is wound around it. The compensation sheave 8 prevents the compensation rope 7 from swinging in the horizontal direction while the car 2 is raised and lowered. The compensatory 8 is rotatably supported in the pit P.

  Here, the long object T in the present embodiment is the main rope 3 and the compen- sion rope 7. The main rope 3 is supported between the car 2 and the hoisting pulley 42, and between the counterweight 6 and the hoisting pulley 42, and the length between them changes according to the raising and lowering of the car 2. . In addition, the compen- sion rope 7 is supported between the car 2 and the compensatory 8 and between the counterweight 6 and the compensatory 8, and the length between them changes as the car 2 moves up and down.

  The long object shake sensor 9 detects the shake state of the long object that the elevator E has, based on the shake information of the building 100 in which the elevator E is installed. In the present embodiment, the long object shake sensor 9 includes an acceleration sensor, and detects acceleration and period as the building 100, for example, as shaking information of a high-rise building. The long object shake sensor 9 is provided in a predetermined part of the building 100 that is separated from the ground in the vertical direction, in the machine room 12 in this embodiment. This is because when the building 100 shakes, the building 100 shakes around the ground as a fulcrum. Based on the shaking information (including acceleration and period) of the building 100, the long object shake detector 9 determines whether or not the shake state of the long object T has become a preset value. The shake state of the long object T is determined. In this embodiment, the long object shake sensor 9 determines whether or not the shake state of the long object T has been set in advance to four set values stored in a storage unit (not shown). The swing state of the object T is determined in four stages. The four setting values are three earthquake setting values based on earthquake (earthquake [low] setting value, earthquake [middle] setting value, earthquake [high] setting value), and one strong wind setting value based on wind. (Strong wind setting value). On the other hand, there are four swinging states of the long object T: earthquake [low], earthquake [middle], earthquake [high], and strong wind. The swing state of the long object T at each set value is a state in which the shake is greatly increased in the order of earthquake [low] set value <earthquake [middle] set value <strong wind set value <earthquake [high] set value. In other words, the long object shake detector 9 determines that the long object T shake state is the earthquake [low] when the shake state of the long object T based on the shake information is equal to or greater than the earthquake [low] set value. If the swinging state of the object T is greater than or equal to the earthquake [medium] setting value, the swinging state of the long object T is the earthquake [medium], and if the swinging state of the long object T is greater than or equal to the strong wind setting value, If the swinging state is strong wind and the swinging state of the long object T is greater than or equal to the earthquake [high] set value, the swinging state of the long object T is determined to be earthquake [high]. The long object shake sensor 9 is electrically connected to the elevator control panel 10, and a shake state signal based on the determined magnitude of the shake of the long object T is input to the elevator control panel 10.

  Here, when each set value is a long-period vibration in the building 100 at an acceleration set in advance by analysis, each set-up device (hereinafter referred to as “the hoistway 11” from the long object T to the hoistway 11 or the hoistway 11). It is determined by the time required for the amplitude of the long object T to grow until it reaches the shortest distance (including the case where the long object T contacts the contact object). For example, the earthquake [low] set value is a shake state of the long object T that can detect an initial stage of long-period vibration. The earthquake [medium] set value is a shake state of the long object T that is 60% to 70% of the amplitude of the long object T in the earthquake [high] set value. The strong wind setting value is a shake state of the long object T that is 80% to 90% of the amplitude of the long object T in the earthquake [high] setting value. The earthquake [high] set value is a swing state of the long object T in which the amplitude of the long object T is the shortest distance from the long object T to the contact object.

  The elevator control panel 10 is a control device and drives and controls at least the hoisting machine 4. In this embodiment, the motor control unit 101, the main microcomputer 102, the signal input unit 103, and the signal output unit 104 are controlled. It is comprised including.

  The motor control unit 101 controls the motor 41 of the hoisting machine 4. The motor control unit 101 controls the motor 41 to a normal rotation, reverse rotation, stop, or the like state based on a command signal from the main microcomputer 102, and puts the car 2 in a state such as ascending, descending, or stopping. .

  The main microcomputer 102 controls the operating state of the elevator E. The main microcomputer 102 is input to the signal input unit 103 and is based on an operation signal output when a passenger operates an operation panel (not shown) provided in the landing 20 on each floor or an operation panel provided in the car 2. The car 2 is raised and lowered to the target floor by outputting a command signal to the motor control unit 101 and driving and controlling the hoisting machine 4. Further, as shown in FIG. 3, the main microcomputer 102 in this embodiment performs either an earthquake control operation or a strong wind control operation based on the shake state signal, the wind speed signal, and the breaking news signal. The main microcomputer 102 performs either an earthquake control operation or a strong wind control operation based on the three conditions of the swinging state of the long object T, the presence / absence of receiving an earthquake early warning, and whether the wind speed is equal to or higher than a predetermined wind speed. I do.

  The signal input unit 103 receives signals from various sensors of the elevator E, the operation signals, and the like. In the present embodiment, the signal input unit 103 receives a shake state signal from the long object shake detector 9, a wind speed signal from the wind speed sensor 110, and a breaking information signal from the emergency earthquake warning device 200.

  The signal output unit 104 outputs a signal for operating various devices of the elevator E and an alarm signal for operating the alarm device 300.

  The wind speed sensor 110 detects the wind speed outside the building 100. In the present embodiment, the wind speed sensor 110 detects the wind speed by rotating the blades receiving wind. The wind speed sensor 110 is provided in the building 100 with its blades exposed to the outside of the building 100. That is, the wind speed sensor 110 detects the strength of the wind received by the building 100. The wind speed sensor 110 is electrically connected to the elevator control panel 10, and a wind speed signal is input to the elevator control panel 10 based on the detected wind speed.

  The earthquake early warning device 200 is an earthquake information transmitting device, and transmits earthquake information, in this embodiment, an earthquake early warning. Here, emergency earthquake alerts immediately after the occurrence of an earthquake, analyze the detection results by a seismometer near the epicenter, estimate the epicenter and magnitude of the earthquake (magnitude), predict the arrival time and seismic intensity of each place, The prediction result is transmitted as earthquake information to various places having a predetermined seismic intensity (for example, seismic intensity 5), that is, notified. The earthquake early warning device 200 is provided outside the building 100 and is electrically connected to the elevator control panel 10 by wire or wirelessly, and a warning signal based on the emergency earthquake bulletin is sent to the elevator control panel 10. Sent. That is, when the elevator control panel 10 receives the breaking signal, it is predicted that an earthquake having a predetermined seismic intensity will occur in the area where the building 100 is built.

  The alarm device 300 is provided in an elevator monitoring room installed inside or outside the building 100, and notifies the elevator monitoring room of the state of the elevator E. The alarm device 300 may include, for example, a speaker, a warning light, or the like, or may be a monitoring system that monitors a plurality of elevators E in an elevator monitoring room.

  Next, the control operation by the elevator control operation system 1 according to the embodiment will be described. As shown in FIG. 3, when receiving the earthquake early warning, the elevator control panel 10 performs an earthquake control operation according to the determined swing state of the long object T. That is, the elevator control panel 10 performs an earthquake control operation when two conditions of receiving an earthquake early warning and a swinging state of the long object T are satisfied. Moreover, the elevator control panel 10 performs a strong wind time control operation according to the determined swing state of the long object T when the detected wind speed is equal to or higher than a predetermined wind speed. That is, the elevator control panel 10 performs a strong wind control operation when two conditions of a wind speed equal to or higher than a predetermined wind speed and a swing state of the long object T are satisfied. Here, the predetermined wind speed is a wind speed that causes a long-period vibration in the building 100 in which the elevator E is installed by the wind, that is, a long-period vibration in the building 100 in the same manner as a long-period ground motion.

  When the elevator control panel 10 receives the earthquake early warning and determines that the swinging state of the long object T is an earthquake [low], the elevator control panel 10 activates the alarm device 300 and issues an alarm as an earthquake control operation. At this time, the elevator control panel 10 does not restrict the operation of the elevator E, that is, the elevator E is continuously operated.

  When the elevator control panel 10 receives the earthquake early warning and determines that the swinging state of the long object T has changed from an earthquake [low] to an earthquake [medium], the elevator control panel 10 suspends the operation of the elevator E as an earthquake control operation. carry out. Here, the operation stop means that the car 2 is landed on the nearest floor when the car 2 is moving up and down, and the door 2 is opened to open the car 2 to the landing 20. On the other hand, the drive control of the hoisting machine 4 based on the operation signal is not performed. In addition, the elevator control panel 10 determines whether or not the nearest floor is a resonance floor where the long object T resonates with the shaking of the building 100 (predetermined based on the natural frequency of the building 100). If it is determined that the nearest floor is the resonance floor, the floor is landed on the non-resonance floor. In addition, the elevator control panel 10 can perform automatic operation return in the case of the control operation during an earthquake. In the elevator control panel 10, the long-period vibration of the building 100 starts to subside, and the swinging state of the long object T continues, for example, for a predetermined time or more and becomes an earthquake [low] set value or less, and the earthquake [medium] setting again. If it becomes the state which does not become more than a value, drive control of the hoisting machine 4 based on an operation signal will be performed, and the restriction | limiting of operation | movement of the elevator E will be cancelled | released.

  When the elevator control panel 10 receives the earthquake early warning and determines that the swinging state of the long object T has changed from an earthquake [medium] to an earthquake [high], the elevator control panel 10 stops the use of the elevator E as an earthquake control operation. To do. Here, the use stop means that the drive control of the hoisting machine 4 and the automatic operation return based on the operation signal are not performed as in the case of the operation stop. When the swinging state of the long object T is an earthquake [high], there is a high possibility that the long object T is in contact with the contact object, and the long object T or the contact object may be damaged. Therefore, the operation is resumed on condition that the inspection is performed by the worker.

  When the elevator control panel 10 determines that the detected wind speed is equal to or higher than the predetermined wind speed and the swinging state of the long object T is an earthquake [low], the elevator control panel 10 issues an alarm as a strong wind control operation in the same manner as the earthquake control operation. The device 300 is activated to give an alarm. At this time, the elevator control panel 10 does not restrict the operation of the elevator E, that is, the elevator E is continuously operated.

  When the elevator control panel 10 determines that the detected wind speed is equal to or higher than the predetermined wind speed and the swinging state of the long object T is changed from earthquake [low] to earthquake [medium], the elevator E is controlled as a strong wind control operation. Carry out driving. Here, the limited operation refers to drive control of the hoisting machine 4 based on the operation signal, but the stop floor based on the operation signal is only the resonance floor or near the resonance floor (for example, the first floor above and below the resonance floor). If it is, it will pass through the stop floor. In other words, even if the passenger attempts to call registration or destination floor registration in the elevator control panel 10 by setting the resonance floor or the first floor above and below the resonance floor as the stop floor of the car 2, the operation is not accepted.

  When the elevator control panel 10 determines that the detected wind speed is equal to or higher than the predetermined wind speed and the swinging state of the long object T has changed from earthquake [medium] to earthquake [high], the control operation during earthquake is controlled as a strong wind control operation. Similarly to the above, the use of the elevator E is stopped.

  As described above, in the control operation system 1 of the elevator E according to the embodiment, when the earthquake early warning is received, the control operation at the time of the earthquake according to the shake state of the long object T is performed, and the wind speed is equal to or higher than the predetermined wind speed. Since the control operation of the strong wind is more frequent than the control operation during the earthquake according to the swinging state of the long object T, the control of the operation of the elevator E is performed, so that the long object shakes due to the long-period vibration of the building 100. Whether it is an earthquake or a wind can be reliably determined. In addition, if the long-period vibration of the building 100 is caused by wind, the control operation for continuously operating the elevator E that is not set to the control operation at the time of earthquake is set for the control operation at the time of strong wind. In this embodiment, the limited operation is set. Has been. The limited operation, which is a control operation during strong winds, is the same as the suspension of operation, which is a control operation during an earthquake, with the condition that the swing state of the long object T is an earthquake [medium]. If the runout is caused by wind, the operation of the elevator E can be continued. Therefore, when the shake of the long object T is caused by the wind, the opportunity for the operation stop of the elevator E can be reduced, and the convenience for the user can be improved.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.

The elevator control operation system according to the embodiment includes a long object shake sensor, an earthquake information transmission device, a wind speed sensor, and a control device. The long object shake sensor determines the shake state of the long object that the elevator has based on the shake information of the building where the elevator is installed. The earthquake information transmitter transmits earthquake information. The wind speed sensor detects the wind speed outside the building. The control device controls the operation of the elevator E. When the control device receives the earthquake information, the control device performs an earthquake control operation according to the shake state of the long object determined by the long object shake detector, and if the wind speed by the wind speed sensor is equal to or higher than the predetermined wind speed, Control operation in strong winds according to the state of vibration of the object. The shake state of the long object is determined based on a plurality of set values. The control operation during earthquake is performed based on the set value for earthquake, and the control operation during strong wind is performed based on the set value for earthquake and the set value for strong wind different from the set value for earthquake. Control operation during an earthquake based on the same set value for earthquakes is an operation stop that can automatically return to operation, and control operation during strong winds is a continuous operation. The setting value for strong winds is a state in which the swinging state of the long object swings larger than the case of the same earthquake setting value. Control operation during strong winds based on setting values for strong winds is an outage that can return to automatic operation, and control operations during earthquakes and strong winds based on the same setting values for earthquakes that swing more than the setting values for strong winds. The control operation is a suspension of use that cannot return to automatic operation.

When the elevator control panel 10 determines that the detected wind speed is equal to or higher than the predetermined wind speed and the swinging state of the long object T has changed from a strong wind to an earthquake [high], as the strong wind control operation, as in the earthquake control operation. , Stop the use of the elevator E.
