Embodiment mode 1
Fig. 1 is a schematic diagram showing an example of an elevator structure.
As shown in fig. 1, an elevator 1 includes a hoistway 2, a hoisting machine 3, a rope 4, a car 5, a counterweight 6, a control panel 7, and a seismic detector 8. The hoistway 2 is formed to penetrate each floor of a building not shown, for example. The hoisting machine 3 is installed in, for example, a machine room not shown. The ropes 4 are wound around the traction machine 3. The car 5 and the counterweight 6 are suspended in the hoistway 2 by the rope 4. The car 5 and the counterweight 6 are driven by the hoisting machine 3 to ascend and descend. The hoisting machine 3 is controlled by a control panel 7.
As shown in fig. 1, the control panel 7 and the seismic detector 8 are provided in the hoistway 2, for example. The control panel 7 and the seismic detector 8 are disposed in a pit, for example. The control panel 7 and the seismic detector 8 may be installed in a machine room or the like, for example. The seismic detector 8 is electrically connected to the control panel 7.
The control panel 7 is electrically connected to the hoisting machine 3 and the maintenance device 9. The maintenance device 9 has a function of communicating with the monitoring center 10. That is, the control panel 7 can communicate with the monitoring center 10 via the maintenance device 9.
The control panel 7 and the maintenance device 9 are provided in, for example, a building in which the elevator 1 is installed. The monitoring center 10 is provided in a building other than the building in which the elevator 1 is installed, for example. The monitoring center 10 is, for example, a server installed in a management company of the elevator 1.
The monitoring center 10 can communicate with the control panels 7 of a plurality of elevators 1, for example. The monitoring center 10 can communicate with a plurality of maintenance apparatuses 9 provided in different buildings, for example.
Fig. 2 is a functional block diagram of an automatic recovery system of an elevator according to embodiment 1.
As shown in fig. 2, the control panel 7 includes an operation control unit 11. The seismic sensor 8 includes a communication unit 12, an acceleration detection unit 13, a sway direction detection unit 14, a sway time detection unit 15, and a self-diagnosis unit 16. The maintenance device 9 includes a probe control unit 17, an automatic diagnosis control unit 18, a storage unit 19, and a notification unit 20. The monitoring center 10 includes a storage unit 21 and an update unit 22.
The operation control unit 11 controls the operation of the elevator 1. The operation control unit 11 controls the movement of the car 5 by controlling the driving of the hoisting machine 3, for example. The operation control unit 11 controls opening and closing of the doors of the elevator 1 by means of a door opening and closing device, not shown, for example.
The communication unit 12 communicates with the control panel 7. The signal transmitted and received between the communication unit 12 and the control panel 7 is not a contact signal, for example. The transmission method between the communication unit 12 and the control panel 7 is, for example, serial transmission. The communication unit 12 transmits information to the control panel 7. The communication unit 12 receives information from the control panel 7. That is, the seismic detector 8 has a function of performing bidirectional communication with the control panel 7. The seismic sensor 8 has a function of performing bidirectional communication with the maintenance device 9 via the control panel 7.
The acceleration detection unit 13 detects a swing due to an earthquake or the like as an acceleration. The acceleration detection unit 13 detects acceleration at all times, for example. The acceleration is represented by, for example, a Gal (Gal) value.
The swing direction detecting unit 14 detects an acceleration in each swing direction. The swing direction includes, for example, a horizontal direction and a vertical direction. As the swing direction, for example, directions corresponding to X, Y, and Z axes perpendicular to each other may be set. As the horizontal direction among the swing directions, for example, a direction corresponding to four azimuths or eight azimuths may be set. The horizontal direction in the swing direction may be set according to the plane shape of the building, for example. The swing direction detection unit 14 detects acceleration in each swing direction at all times, for example. The acceleration in each swing direction is represented by, for example, a Gal value associated with the direction.
The swing direction detecting unit 14 may calculate the acceleration for each swing direction by, for example, decomposing the acceleration detected by the acceleration detecting unit 13. The swing direction detecting unit 14 may detect acceleration in each swing direction by a plurality of sensors corresponding to the swing directions, for example.
The wobbling time detecting unit 15 detects a wobbling time. The swing time is, for example, a time during which the swing continues at an acceleration exceeding a preset threshold. The swing time is, for example, a time during which the acceleration detector 13 continuously detects acceleration exceeding a threshold value. For example, when the interval from the end time of the 1 st wobble time to the start time of the 2 nd wobble time is shorter than a predetermined time, the wobble time detector 15 may detect a period from the start time of the 1 st wobble time to the end time of the 2 nd wobble time as one continuous wobble time. The oscillation time is expressed in seconds or minutes, for example.
The communication unit 12 transmits various numerical values detected by the acceleration detection unit 13, the swing direction detection unit 14, and the swing time detection unit 15 to the control panel 7, for example. The communication unit 12 transmits various numerical values when the acceleration detection unit 13 detects, for example, an acceleration exceeding a threshold value. The control panel 7 sends, for example, various values to the maintenance device 9.
The communication unit 12 transmits, for example, a numerical value indicating the maximum acceleration detected by the acceleration detection unit 13. The communication unit 12 transmits, for example, a numerical value indicating the maximum acceleration in each swing direction detected by the swing direction detection unit 14. The communication unit 12 transmits, for example, a numerical value indicating the maximum wobbling time detected by the wobbling time detection unit 15. In this way, the seismic sensor 8 detects the sway as acceleration, and outputs a numerical value based on the detected acceleration.
The maximum acceleration is, for example, the maximum value of the acceleration detected by the acceleration detection unit 13 during a period from when the acceleration detected by the acceleration detection unit 13 exceeds a threshold value to when the acceleration becomes equal to or less than the threshold value. The maximum acceleration for each swing direction is, for example, the maximum value of the acceleration detected by the swing direction detecting unit 14 during the period.
The probe control unit 17 transmits a reset signal to the seismic probe 8, for example. The seismic detector 8 stops the output of the acceleration-based value, for example, when receiving a reset signal.
The probe control unit 17 periodically checks whether or not the seismic probe 8 is operating (active check), for example. The probe control unit 17 transmits a request signal to the seismic probe 8, for example. The communication unit 12 returns a response signal to the request signal, for example. For example, when the response signal is received within a predetermined time from the transmission of the request signal, the probe control unit 17 determines that the seismic probe 8 is operating. For example, when the response signal is not received within a predetermined time from the transmission of the request signal, the probe control unit 17 determines that the seismic probe 8 is not operating or that the connection between the control panel 7 and the seismic probe 8 is disconnected.
The probe control unit 17 transmits a functional diagnosis instruction to the seismic probe 8, for example. The self-diagnosis unit 16 performs a diagnosis operation based on a functional diagnosis command, for example. The diagnostic operation is, for example, a point inspection as to whether or not acceleration is detected or the seismic sensor 8 is reset normally. The communication unit 12 returns the diagnosis result of the self-diagnosis unit 16 to the maintenance device 9, for example.
The automatic diagnosis control unit 18 has a function of executing an automatic diagnosis operation via the control panel 7. The automatic diagnosis operation is an operation performed after an actual earthquake occurs, and is used to determine whether or not the elevator 1 can be automatically recovered. By the automatic diagnosis operation, for example, it is determined whether or not the equipment of the elevator 1 is damaged.
The automatic diagnosis control unit 18 executes an automatic diagnosis operation when the maximum acceleration output from the seismic sensor 8 is within a predetermined range equal to or less than a general reference value, for example. The general reference value is a value set in advance according to, for example, a vibration resistance standard prescribed by law. The general reference value is represented by a Gal value, for example.
The automatic diagnosis control unit 18 executes an automatic diagnosis operation when, for example, the maximum acceleration output from the seismic sensor 8 exceeds a general reference value but a numerical value based on the acceleration output from the seismic sensor 8 satisfies a single reference. The individual reference is set for each building or each elevator 1 in which the elevator 1 is installed, for example. That is, the content of the individual reference may differ from building to building or elevator 1 to elevator.
The storage unit 19 of the maintenance device 9 stores individual reference data 23. The individual reference data 23 is, for example, data indicating individual references set for the elevator 1 controlled by the control panel 7 connected to the maintenance device 9 or the building in which the elevator 1 is installed.
The individual reference of a certain elevator 1 or a building in which the elevator 1 is installed is set based on, for example, an acceleration based on a sway in which no article damage has occurred in the elevator 1 in the past. The individual reference is set, for example, based on the acceleration output from the seismic detector 8 provided in the elevator 1 or the building in the past. The individual reference is set to, for example, an upper limit value based on the value of the acceleration output by the seismic detector 8.
The individual reference includes, for example, a numerical value indicating the maximum acceleration of the swing that has not caused the elevator 1 to cause damage to the article in the past. The value may be, for example, a value larger than a general reference value. The automatic diagnosis control unit 18 executes the automatic diagnosis operation, for example, when the maximum acceleration due to the earthquake exceeds the general reference value, but the maximum acceleration is equal to or less than the value included in the individual reference. For example, when the maximum acceleration due to an earthquake exceeds the value included in the individual reference, the automatic diagnosis control unit 18 does not perform the automatic diagnosis operation.
The individual reference includes, for example, a numerical value indicating the maximum acceleration in each swing direction of the swing that has not caused the elevator 1 to generate the article damage in the past. The value may be, for example, a value larger than a general reference value. The automatic diagnosis control unit 18 executes the automatic diagnosis operation, for example, when the maximum acceleration in each sway direction due to the earthquake is equal to or less than the value included in the individual reference even if the maximum acceleration due to the earthquake exceeds the general reference value. For example, when the maximum acceleration in each swing direction due to an earthquake exceeds the value included in the individual reference, the automatic diagnosis control unit 18 does not perform the automatic diagnosis operation.
The individual reference includes, for example, a numerical value indicating the maximum swing time of the swing that has not caused the elevator 1 to generate article damage in the past. The automatic diagnosis control unit 18 executes the automatic diagnosis operation, for example, when the maximum oscillation time due to the earthquake is equal to or less than the value included in the individual reference even if the maximum acceleration due to the earthquake exceeds the general reference value. For example, when the maximum oscillation time due to an earthquake exceeds the value included in the individual reference, the automatic diagnosis control unit 18 does not perform the automatic diagnosis operation.
The individual reference may include two or more of a numerical value representing the maximum acceleration of the sway in which the article damage has not occurred in the past, a numerical value representing the maximum acceleration in each sway direction, and a numerical value representing the maximum sway time, for example. The automatic diagnosis control unit 18 may determine whether or not to execute the automatic diagnosis operation based on a result of comparison between two or more of the maximum acceleration output from the seismic detector 8, the maximum acceleration for each sway direction, and the maximum sway time with individual references, for example.
The notification unit 20 notifies the monitoring center 10. The notification unit 20 notifies the monitoring center 10 of information relating to the operation of the maintenance device 9, for example. The notification unit 20 notifies the monitoring center 10 of information indicating the state of the elevator 1 obtained from the control panel 7, for example. The notification unit 20 notifies the monitoring center 10 of information obtained from the seismic detector 8, for example. The notification unit 20 notifies the monitoring center 10 of, for example, the maximum acceleration for each sway direction, the maximum sway time, and the like, which are output by the seismic detector 8 when an earthquake occurs.
For example, when it is determined that the elevator 1 is not damaged based on the result of the automatic diagnosis operation, the notification unit 20 notifies the monitoring center 10 of the fact.
For example, when determining that the elevator 1 has been damaged by an article based on the result of the automatic diagnosis operation, the notification unit 20 issues an operation request to the monitoring center 10 for a maintenance worker.
For example, when the numerical value based on the acceleration output from the seismic detector 8 does not satisfy the individual reference, the notification unit 20 issues an operation request to the monitoring center 10 for the maintenance worker.
The maintenance worker performs the spot inspection work of the elevator 1 in accordance with the departure application. The maintenance worker reports completion to the monitoring center 10 after the completion of the work. The completion report can be made via the control panel 7 or the maintenance device 9, for example. The completion report may be made, for example, directly to the monitoring center 10. The content of the completion report includes information indicating whether or not the elevator 1 has damaged the article, for example.
The storage unit 21 of the monitoring center 10 stores the accumulated data 24 and the individual reference data 25.
The accumulated data 24 is, for example, data based on the acceleration value outputted from the seismic sensor 8 corresponding to the elevator 1 to be monitored by the monitoring center 10 in the past. The output data of the plurality of seismic sensors 8 corresponding to different elevators 1 or different buildings may be contained in the accumulation data 24. The accumulated data 24 includes, for example, a maximum acceleration for each swing direction, a maximum swing time, and the like.
The individual reference data 25 is, for example, data indicating individual references set for the elevator 1 to be monitored by the monitoring center 10 or a building in which the elevator 1 is installed. A plurality of individual references corresponding to different elevators 1 or different buildings may be contained in the individual reference data 25. The individual reference data 25 is set based on the accumulated data 24, for example.
The updating unit 22 changes the individual reference for the building or the elevator 1 corresponding to the seismic probe 8 in the individual reference data 25, for example, based on the latest output data of the seismic probe 8. The updating unit 22 changes, for example, the individual reference data 23 corresponding to the changed individual reference in the individual reference data 25. That is, the updating unit 22 updates the individual reference stored in the maintenance device 9. The individual reference data 23 stored in the maintenance device 9 is not changed depending on, for example, the operation of the control panel 7 and the operation of the maintenance device 9.
For example, when the maximum acceleration due to an earthquake exceeds a general reference value, the updating unit 22 sets the numerical value based on the acceleration output from the earthquake detector 8 as a new individual reference when the numerical value does not satisfy the individual reference and a completion report indicating that the elevator 1 has not damaged the article exists. That is, for example, when the present swing is larger than the swing that has not caused the article damage to the elevator 1 in the past but the elevator 1 does not cause the article damage, the updating unit 22 corrects the individual reference upward.
For example, when the maximum acceleration due to an earthquake exceeds a general reference value, the updating unit 22 sets a numerical value based on the acceleration output from the earthquake detector 8 as a new individual reference when the individual reference is satisfied and a completion report indicating that the elevator 1 has damaged the article exists. That is, for example, when the elevator 1 has an article damage although the current swing is smaller than the swing that has not caused the article damage to the elevator 1 in the past, the update unit 22 corrects the individual reference downward.
Fig. 3 is a diagram for explaining recovery of an elevator after an earthquake occurs.
Fig. 3 shows an example of processing corresponding to the value of the maximum acceleration output by the seismic detector 8. As shown in fig. 3, as a reference of the maximum acceleration output from the seismic detector 8, for example, Gal values corresponding to "extra low", "high", and "diagnosis" are set. High corresponds to, for example, a general reference value set for the elevator 1 against the earthquake level a. The "diagnosis" corresponds to, for example, a general reference value set for the elevator 1 for the earthquake resistance level S.
For example, in the case where the maximum acceleration output by the seismic detector 8 is "ultra low" or less, the normal operation of the elevator 1 is continued.
For example, when the maximum acceleration output from the seismic detector 8 is greater than "extra low" and equal to or less than "low", the elevator 1 is automatically reset after a predetermined time from the temporary stop. The elevator 1 starts to operate again after automatic reset.
For example, when the maximum acceleration output from the seismic sensor 8 is greater than "low" and equal to or less than "high", the automatic diagnosis operation of the elevator 1 is performed at the earthquake resistance level a and the earthquake resistance level S.
For example, when the maximum acceleration output from the earthquake detector 8 is greater than "high" and equal to or less than "diagnosis", the automatic diagnosis operation of the elevator 1 at the earthquake-resistant level S is performed.
For example, conventionally, when the maximum acceleration output from the seismic detector 8 is larger than "high", the elevator 1 of the earthquake-resistant class a needs to be recovered by a maintenance worker. For example, when the maximum acceleration output from the seismic sensor 8 is larger than "diagnosis", the elevator 1 of the earthquake-resistant level S needs to be recovered by a maintenance worker. In contrast, according to embodiment 1, even when the maximum acceleration output from the seismic sensor 8 is greater than "high" or "diagnostic", the automatic diagnostic operation of the elevator 1 can be performed based on the individual reference.
Fig. 4 is a flowchart showing an operation example of an automatic recovery system for an elevator according to embodiment 1.
When an earthquake occurs, the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output from the seismic sensor 8 is "extremely low" or less (step S101). When it is determined in step S101 that the maximum acceleration is "extremely low" or less, the service of the elevator 1 is continued.
When it is determined in step S101 that the maximum acceleration is greater than "extra low", the elevator 1 is stopped (step S102). The automatic diagnosis control unit 18 determines whether or not the maximum acceleration output from the seismic sensor 8 is "low" or less (step S103). If it is determined in step S103 that the maximum acceleration is "low" or less, the elevator 1 automatically resets after 1 minute, for example (step S104). After step S104, the service of elevator 1 is continued.
When it is determined in step S103 that the maximum acceleration is greater than "low", the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output from the seismic detector 8 is equal to or less than "high" (step S105). If it is determined in step S105 that the maximum acceleration is "high" or less, the process of step S108 is performed.
When it is determined in step S105 that the maximum acceleration is greater than "high", the automatic diagnosis control unit 18 determines whether or not the earthquake-resistant level of the elevator 1 is the earthquake-resistant level S (step S106). If it is determined in step S106 that the acceleration is the earthquake resistance level S, the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output from the earthquake detector 8 is equal to or less than "diagnosis" (step S107). If it is determined in step S107 that the maximum acceleration is equal to or less than "diagnosis", the process of step S108 is performed.
In step S108, the notification unit 20 notifies the monitoring center 10. The content notified in step S108 is, for example, content indicating that an automatic diagnostic operation is performed. After step S108, the automatic diagnosis control unit 18 performs an automatic diagnosis operation of the elevator 1 (step S109). The automatic diagnosis control unit 18 determines whether or not the elevator 1 has a damage to the article based on the result of the automatic diagnosis operation (step S110). If it is determined in step S110 that the elevator 1 is not damaged, the notification unit 20 notifies the monitoring center 10 (step S111). The content notified in step S111 is, for example, content indicating that the elevator 1 has no damage to the article. In this case the service of the elevator 1 is continued.
If it is determined in step S110 that the elevator 1 has an article damage, the notification unit 20 notifies the monitoring center 10 (step S112). The content notified in step S112 is, for example, a work request of the maintenance worker. The maintenance worker checks and repairs the elevator 1 in accordance with the departure request (step S113). The maintenance worker reports completion to the monitoring center 10 after the completion of the work (step S114).
If it is determined in step S106 that the earthquake-resistant level is not the earthquake-resistant level S, the process of step S115 is performed. When it is determined in step S107 that the maximum acceleration is greater than "diagnosis", the process of step S115 is performed.
In step S115, the automatic diagnosis control unit 18 determines whether or not the automatic diagnosis operation using the individual reference can be executed. The determination of step S115 depends on whether or not there is a maintenance contract for the elevator 1 relating to the automatic diagnostic operation using the individual reference, for example. If it is determined in step S115 that the automatic diagnosis operation using the individual reference cannot be executed, the process of step S112 is performed.
If it is determined in step S115 that the automatic diagnosis operation using the individual reference can be executed, the automatic diagnosis control unit 18 acquires output data based on the acceleration due to the current earthquake from the seismic sensor 8 (step S116). The notification unit 20 notifies the monitoring center 10 of the output data (step S117). The automatic diagnosis control unit 18 determines whether or not the acquired output data satisfies the individual criterion (step S118).
If it is determined in step S118 that the output data satisfies the individual reference, the process of step S108 is performed. If it is determined in step S118 that the output data does not satisfy the individual reference, the process of step S112 is performed.
In embodiment 1, the communication unit 12 of the seismic sensor 8 has a function of performing bidirectional communication with the control panel 7 of the elevator 1. The communication unit 12 transmits, for example, a numerical value indicating the maximum acceleration for each swing direction, and a numerical value indicating the maximum swing time to the control panel 7. That is, the output data of the seismic detector 8 is not a simple contact signal corresponding to the magnitude of the wobble, but a detailed numerical value showing the wobble characteristic. Therefore, according to embodiment 1, it is possible to expand services such as elevator control operation and automatic diagnosis operation at the time of occurrence of an earthquake by using output data of the earthquake detector. Further, according to embodiment 1, the connection state between the seismic sensor and the control panel can be easily checked.
In embodiment 1, the seismic sensor 8 may have a vibration generating unit, for example. The vibration generating unit has a function of generating vibration by a servo motor or the like, for example. The self-diagnosis unit 16 operates the vibration generation unit in accordance with a functional vibration command transmitted from the probe control unit 17, for example. The self-diagnosis unit 16 determines whether or not the various values detected by the acceleration detection unit 13, the swing direction detection unit 14, and the swing time detection unit 15 are normal after the vibration generation unit starts operating, for example. The communication unit 12 returns various values and the determination result of the self-diagnosis unit 16 to the maintenance device 9, for example. Thus, it is possible to easily confirm that the seismic sensor is operating normally when an earthquake actually occurs. The vibration generator may be a device separate from the seismic sensor 8 as long as it can transmit vibration to the seismic sensor 8.
In embodiment 1, the automatic diagnosis control unit 18 has a function of executing an automatic diagnosis operation of the elevator 1 after an earthquake occurs, and executes the automatic diagnosis operation when the maximum acceleration output from the earthquake detector 8 is included in a predetermined range not more than a preset general reference value. The storage unit 19 stores individual references set for each building or each elevator 1. The automatic diagnosis control unit 18 performs the automatic diagnosis operation when the maximum acceleration output by the seismic probe 8 exceeds the general reference value but the numerical value based on the acceleration output by the seismic probe 8 satisfies the individual reference stored in the storage unit 19. Therefore, according to embodiment 1, the automatic diagnosis operation can be performed according to the earthquake resistance of each building or each elevator. As a result, the proportion of elevators that automatically recover after an earthquake occurs can be increased. Moreover, the burden of maintenance workers after the occurrence of the earthquake can be reduced.
In embodiment 1, the individual reference includes, for example, the maximum acceleration of the elevator 1 in the past without causing the swing of the article damage. The automatic diagnosis control unit 18 determines whether to execute an automatic diagnosis operation, for example, based on a result of comparison between the maximum acceleration output from the seismic detector 8 and a single reference. Therefore, the automatic diagnosis operation can be performed according to the earthquake resistance of each building or each elevator.
In embodiment 1, the individual reference includes, for example, the maximum acceleration in each swing direction of the swing that has not caused the elevator 1 to cause damage to the article in the past. The automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation, for example, based on a result of comparison between the maximum acceleration in each swing direction output from the seismic detector 8 and the individual reference. In this case, whether to perform the automatic diagnosis operation is determined in consideration of a case where the earthquake resistance of the building or the elevator differs depending on the sway direction. Thus, an automatic diagnostic operation can be performed according to the specific seismic capacity of each building or each elevator.
In embodiment 1, the individual reference includes, for example, the maximum swing time of the swing that has not caused the elevator 1 to generate the article damage in the past. The automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation based on a result of comparison between the maximum oscillation time output from the seismic detector 8 and the individual reference, for example. In this case, whether to perform the automatic diagnosis operation is determined in consideration of a case where the earthquake resistance of the building or the elevator differs depending on the swing time. Thus, an automatic diagnostic operation can be performed according to the specific seismic capacity of each building or each elevator.
In embodiment 1, the automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation based on the comparison result between at least two of the maximum acceleration output from the seismic probe 8, the maximum acceleration in each sway direction, and the maximum sway time, and the individual reference, for example. Thus, an automatic diagnostic operation can be performed based on the more specific seismic capacity of each building or each elevator.
In embodiment 1, the individual reference is set based on, for example, an acceleration based on a swing that has not caused damage to the elevator 1 in the past. Therefore, the automatic diagnosis operation can be performed according to the actual earthquake resistance of each building or each elevator.
In embodiment 1, the updating unit 22 updates the individual reference stored in the storage unit 19, for example. The automatic diagnosis control unit 18 and the storage unit 19 are provided in, for example, a maintenance device 9 installed in the same building as the elevator 1. The updating unit 22 is provided in, for example, the monitoring center 10 that can communicate with the maintenance device 9. Therefore, it is possible to prevent the maintenance worker from erroneously changing the individual reference at the time of the spot inspection of the elevator.
In embodiment 1, for example, when the maximum acceleration output from the seismic detector 8 exceeds a general reference value, the updating unit 22 sets the numerical value based on the acceleration output from the seismic detector 8 as the individual reference when the numerical value does not satisfy the individual reference and the maintenance worker confirms that the elevator 1 has not been damaged. That is, the updating unit 22 corrects the individual reference of the elevator 1 or the building having a high earthquake resistance upward. Therefore, the automatic diagnosis operation can be performed according to the actual earthquake resistance of each building or each elevator.
In embodiment 1, for example, when the maximum acceleration output from the seismic detector 8 exceeds a general reference value, the updating unit 22 sets the numerical value based on the acceleration output from the seismic detector 8 as the individual reference when the numerical value satisfies the individual reference and the maintenance worker confirms that the elevator 1 has a damage to the article. That is, the updating unit 22 corrects the individual reference of the elevator 1 or the building having low earthquake resistance downward. Therefore, the automatic diagnosis operation can be performed according to the actual earthquake resistance of each building or each elevator.
In embodiment 1, the individual reference regarding a certain elevator 1 or a building in which the elevator 1 is installed is set based on, for example, an acceleration output from an earthquake detector 8 installed in a place different from the elevator 1 or the building in the past. The individual reference for a certain elevator 1 can be set, for example, based on the acceleration output from the seismic sensor 8 installed in another elevator 1 having the same or similar machine type and hoistway size. The individual reference for a certain building can be set, for example, based on the acceleration output from the seismic sensor 8 installed in another building that is the same or similar, such as the number of floors, the number of years of the building, the plane shape, the structural material, and the foundation. In this case, for example, an appropriate individual reference can be set for a newly installed elevator or a newly completed building.
In embodiment 1, the probe control unit 17, the automatic diagnosis control unit 18, the storage unit 19, and the notification unit 20 may be used as the functions of the control panel 7. In this case, it is also possible to perform an automatic diagnosis operation according to the earthquake resistance of each building or each elevator.
Fig. 5 is a hardware configuration diagram of the maintenance device.
The functions of the probe control unit 17, the automatic diagnosis control unit 18, the storage unit 19, and the notification unit 20 in the maintenance device 9 can be realized by a processing circuit. The processing circuitry may be dedicated hardware 50. The processing circuitry may have a processor 51 and a memory 52. The processing circuit may be a part of dedicated hardware 50, and further include a processor 51 and a memory 52. Fig. 5 shows an example in which the processing circuit is partly formed as dedicated hardware 50 and has a processor 51 and a memory 52.
Where at least a portion of the processing circuitry is at least one dedicated hardware 50, the processing circuitry may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.
In the case where the processing circuit has at least one processor 51 and at least one memory 52, the respective functions of the probe control section 17, the automatic diagnosis control section 18, the storage section 19, and the notification section 20 are realized by software, firmware, or a combination of software and firmware. The software and firmware are described as programs and stored in the memory 52. The processor 51 realizes the functions of the respective sections by reading out and executing the program stored in the memory 52. The processor 51 is also called a CPU (Central processing unit), a Central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. The Memory 52 is a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like, a magnetic Disk, a flexible Disk, an optical Disk, a compact Disk, a mini Disk, a DVD (Digital Versatile Disk), or the like.
In this way, the processing circuitry can implement the functions of the maintenance device 9 by hardware, software, firmware, or a combination thereof. The functions of the control panel 7, the seismic sensor 8, and the monitoring center 10 are also realized by a processing circuit similar to the processing circuit shown in fig. 5.
