The elevator 1 has a control device 14 . The control device 14 is provided in the machine room 4, for example. The control device 14 is a device that controls the operation of the elevator 1 . Operation of the elevator 1 includes, for example, normal operation, earthquake control operation, and diagnostic operation. Here, the earthquake control operation is a control operation immediately after the occurrence of an earthquake to protect elevator equipment or evacuate passengers. Diagnosis operation is a control operation after the shaking of the earthquake subsides, automatically diagnosing whether or not restoration is possible. The control device 14 controls the air traffic control operation when an earthquake occurs based on the seismic response information. The seismic response information is, for example, a signal input from a response sensor. Here, the response sensor is a sensor that detects a seismic response due to an earthquake. The response sensors include, for example, the appliance response sensor 13 or each floor response sensor 12 . The control device 14 includes an earthquake control operating section 15 and a diagnostic operating section 16 . The earthquake control operation section 15 is a part that controls the earthquake control operation. The diagnostic operation section 16 is a part that controls diagnostic operation.

The control device 14 comprises a determination device 17 . In this example, the determination device 17 is mounted on the control device 14 as part of the device, for example. The judging device 17 is a device for judging the influence of the earthquake on the elevator equipment before diagnostic operation. The determination device 17 determines the contents of diagnosis in diagnostic operation based on the determined influence of the earthquake. The determination device 17 includes a response acquisition unit 18 , a damage criteria storage unit 19 , a damage level determination unit 20 , a damage level storage unit 21 , and a diagnosis content determination unit 22 .

The response acquisition unit 18 is a part that acquires response data. The response data includes seismic response information for each of the plurality of elevator equipment on each of the plurality of floors of the building 2 . Here, multiple floors in the response data may include the machine room 4 or the pit 5 . In this example, the response acquisition unit 18 acquires information on the seismic response of the elevator equipment to which the equipment response sensor 13 is installed based on the information on the seismic response obtained by the equipment response sensor 13 arranged on each floor. Alternatively, the response acquisition unit 18 obtains information on the seismic response of each of the plurality of elevator devices placed on each floor based on the information on the seismic response of the building 2 acquired by the floor response sensor 12 placed on each floor. may be obtained. Here, each floor response sensor 12 may be provided instead of the device response sensor 13 on some or all of the floors. Alternatively, each floor response sensor 12 may be provided together with the equipment response sensor 13 on some or all of the floors.

Note that the response acquisition unit 18 may acquire response data using a response estimation model. The response estimation model is a model for estimating the seismic response of a portion where no response sensor is provided based on seismic response information input from the response sensor. Alternatively, the response acquisition unit 18 may correct the acquired response data using a response estimation model. The response estimation model includes, for example, a building response model for estimating the seismic response of the building 2, an elevator response model for estimating the seismic response of elevator equipment, and the like.

The damage criteria storage unit 19 is a part that stores judgment criteria for equipment damage levels that indicate the damage status of each elevator equipment. A criterion is set in advance for each of the plurality of elevator devices. The criterion is, for example, a reference value for seismic response. The criteria are set based on, for example, strength design standards for each elevator device, information on past earthquake damage, or the results of earthquake damage simulations. In this example, criteria are set for three levels of equipment damage. Lv., which is the lowest equipment damage level among the three equipment damage levels. 1 is a device damage level indicating, for example, "minor damage that does not hinder driving". Lv., which is the second lowest equipment damage level among the three equipment damage levels. 2 is a device damage level indicating, for example, "the vehicle is drivable but has moderate damage". Lv., which is the highest equipment damage level among the three equipment damage levels. 3 is a device damage level indicating, for example, "a damage situation causing serious damage that makes it impossible to drive". Here, different standards may be set for each of the plurality of elevator devices as the criteria for determining the equipment damage level in each stage.

The damage level determination unit 20 determines the equipment damage level of each of the plurality of elevator equipment on each of the plurality of floors based on the equipment damage level determination criteria and the response data acquired by the response acquisition unit 18. is. The damage level determination unit 20 refers to the determination criteria stored in the damage criteria storage unit 19, for example. In this example, the damage level determination unit 20 determines the equipment damage level Lv. Elevator equipment for which a seismic response lower than the reference value of 1 is acquired may be determined to be undamaged.

The damage level storage unit 21 is a part that stores the damage level determined by the damage level determination unit 20 . The damage level storage unit 21 stores the equipment damage level of each of the plurality of elevator equipment on each of the plurality of floors.

The diagnostic content determination unit 22 is a part that determines the diagnostic content to be performed in the diagnostic operation based on the information stored in the damage level storage unit 21 . The contents of the diagnosis include, for example, information on the range of floors on which the car 8 or the counterweight 9 travels during diagnostic operation. Since diagnosis is performed by traveling of the car 8 or the counterweight 9 in the diagnostic operation, the range in which the car 8 or the counterweight 9 travels is the diagnostic range of the diagnostic operation. Further, the diagnostic content includes, for example, a diagnostic method in the diagnostic range. The diagnosis method includes, for example, the running speed of the car 8 or the counterweight 9 running on each floor, or the number of times of running on each floor.

The diagnostic content determination unit 22 outputs the determined diagnostic content to the diagnostic operation unit 16 to cause the diagnostic operation unit 16 to perform diagnostic operation based on the diagnostic content. In addition, the diagnostic content may also include whether diagnostic operation is possible. When it is determined that the diagnostic operation is not possible, the diagnostic operation section 16 does not perform the diagnostic operation.

Next, the function of the determination device 17 will be described with reference to FIG.
FIG. 2 is a flowchart showing functions of the determination device according to Embodiment 1. FIG.

When an earthquake occurs in step S101, the P-wave sensor 10 and the S-wave sensor 11 determine whether the detected acceleration exceeds a set threshold. P-wave sensor 10 operates to output a P-wave sense signal to controller 14 when the detected acceleration exceeds a set threshold. S-wave sensor 11 operates to output an S-wave sensing signal corresponding to the exceeded threshold to controller 14 when the detected acceleration exceeds a set threshold.

Next, in step S 102 , controller 14 determines whether P-wave sensor 10 has been activated based on whether a P-wave sensing signal is input from P-wave sensor 10 . When determining that P-wave sensor 10 is not operating, controller 14 continues normal operation of elevator 1 as shown in step S103. On the other hand, when determining that the P-wave sensor 10 has operated, the control device 14 causes the earthquake control operation section 15 to perform earthquake control operation.

In step S<b>104 , the earthquake control operation unit 15 determines whether the S wave sensor 11 has been activated based on whether the S wave sensing signal is input from the S wave sensor 11 . In this example, the earthquake control operation unit 15 determines whether the S-wave detector 11 has been activated based on the S-wave sensing signal corresponding to the low level threshold. When determining that the S-wave detector 11 is not operating, the earthquake control operation unit 15 stops the car 8 at the nearest floor so that passengers can get off the car 8, as shown in step S105. . After that, the earthquake control operation unit 15 suspends the running of the car 8 for a preset fixed time, as shown in step S106. After that, when it is confirmed that the shaking of the earthquake has subsided, the earthquake control operation section 15 restores the elevator 1 to normal operation as shown in step S103.

On the other hand, in step S104, when an earthquake of such magnitude that the earthquake control operation unit 15 determines that the S-wave detector 11 has been activated, there is a possibility that earthquake damage has occurred in one of the elevator devices. be. At this time, the control device 14 causes the determination device 17 to determine the influence of the earthquake on the elevator equipment. In this example, the determination of the earthquake influence by the determination device 17 is performed after the shaking of the earthquake subsides. That is, when it is determined in step S104 that the S-wave detector 11 has operated, the earthquake control operation section 15 stops the car 8 at the nearest floor so that passengers can get off as shown in step S107. . After that, the earthquake control operation unit 15 suspends the running of the car 8 for a predetermined period of time, as shown in step S108. After that, when it is confirmed that the shaking of the earthquake has subsided, the earthquake control operation section 15 causes the determination device 17 to determine the influence of the earthquake on the elevator equipment.

The determination device 17 determines the influence of the earthquake on the elevator equipment, for example, as follows. In step S109, based on the response data acquired by the response acquisition unit 18 and the determination criteria stored in the damage criteria storage unit 19, the damage level determination unit 20 determines whether the plurality of elevator equipment on each of the plurality of floors Determine the damage level of each device.

Next, in step S110, the diagnostic content determination unit 22 of the determination device 17 determines that the equipment damage level of each of the plurality of elevator equipment in the machine room 4 or the pit 5 is Lv. It is determined whether the number is 2 or less. If the equipment damage level in the machine room 4 or pit 5 is Lv. If there is elevator equipment higher than 2, the determination device 17 suspends the operation of the elevator 1 until the manual inspection by the technician is finished, as shown in step S116. At this time, the control device 14 does not allow the diagnostic operation section 16 to perform the diagnostic operation. On the other hand, if the equipment damage level of each of the plurality of elevator equipment in the machine room 4 or pit 5 is Lv. If it is less than or equal to 2, as shown in step S111, the diagnostic content determining unit 22 determines the range of floors that can be operated in diagnostic driving. The range of drivable floors determined here is the diagnostic range in the diagnostic operation.

Next, in step S112, the determination device 17 determines whether the floor on which the car 8 is currently stopped is within the diagnosis range. When the car 8 has not stopped within the diagnostic range, the determination device 17 suspends the operation of the elevator 1 until the manual inspection by the technical engineer is completed, as shown in step S116. At this time, the control device 14 does not allow the diagnostic operation section 16 to perform the diagnostic operation. On the other hand, when the car 8 is stopped within the diagnostic range, the diagnostic content determination unit 22 determines the diagnostic method within the diagnostic range, as shown in step S113. Based on the diagnostic content determined by the diagnostic content determination unit 22 in this manner, the diagnostic operation unit 16 performs diagnostic operation.

In step S114, the diagnostic operation section 16 starts diagnostic operation. As shown in step S115, the diagnostic operation unit 16 determines whether an abnormality is detected in the elevator 1 during diagnostic operation. When the diagnostic operation ends without detecting any abnormality, the diagnostic operation unit 16 restores the elevator 1 to normal operation as shown in step S103. On the other hand, when an abnormality is detected in the diagnostic operation, the diagnostic operation section 16 immediately stops the diagnostic operation. After that, as shown in step S116, the diagnostic operation unit 16 suspends the operation of the elevator 1 until the manual inspection by the technical engineer is completed.

Next, an example of the data structure in the determination device 17 will be described with reference to FIG.
3 is a diagram showing an example of a data structure in the determination device according to Embodiment 1. FIG.

The response data acquired by the response acquisition unit 18 includes information on the seismic response of each of the plurality of elevator equipment on each of the plurality of floors. Here, equipment E1, equipment E2, and equipment E3 are exemplified as elevator equipment. The acceleration of the device E1 is acquired as the information on the seismic response of the device E1. The speed of the device E2 is acquired as information on the seismic response of the device E2. The displacement of the device E3 is acquired as the information of the seismic response of the device E3. For example, when the equipment E1 is placed only on the first floor, the response data includes information on the seismic response of the equipment E1 only on the first floor. For example, when the equipment E2 is placed on each floor, the response data includes information on the seismic response of the equipment E2 on each floor. For example, when the equipment E3 is arranged over a plurality of floors, the response data includes information on the seismic response of the parts of the equipment E3 corresponding to each floor.

The criteria stored in the damage criteria storage unit 19 are set for each of the plurality of elevator devices. In this example, the equipment damage level Lv. The reference value of the criterion corresponding to 1 is set to 50 Gal. Also, if the equipment damage level Lv. The reference value of the criterion corresponding to 2 is set to 100 Gal.

The damage level storage unit 21 stores the equipment damage level determined by the damage level determination unit 20 . The equipment damage level indicates the damage status of each of the plurality of elevator equipment on each of the plurality of floors.

Next, an example of determination of earthquake influence by the determination device 17 will be described with reference to FIG.
FIG. 4 is a diagram showing an example of earthquake influence determination by the determination device according to the first embodiment.

In the table of FIG. 4, the equipment damage levels determined by the damage level determining unit 20 are indicated by numerical values. In the table of FIG. 4, the part where the numerical value 1 is shown indicates that the equipment damage level of the elevator equipment on the floor is Lv. It represents that it was determined to be 1. In the table of FIG. 4, a blank part indicates that the elevator equipment was determined to be undamaged on the floor. In the example shown in FIG. 4, the elevator equipment located in machine room 4 and pit 5 has been determined to be undamaged. Also, in this example, the device damage level of the device E3 on the 7th floor is Lv. 3.

At this time, the equipment damage level of each of the plurality of elevator equipment in the machine room 4 and the pit 5 is Lv. Since it is less than or equal to 2, the diagnostic content determination unit 22 determines the range of floors that can be operated in the diagnostic operation as the diagnostic range. In this example, the device damage level is Lv. Since the elevator equipment determined to be 3 is located on the 7th floor, the diagnosis content determining unit 22 defines the range of floors in which neither the car 8 nor the counterweight 9 passes through the 7th floor as the diagnosis range. Here, the car 8 and the counterweight 9 run symmetrically and in opposite directions with respect to the intermediate floor. Therefore, the range of operable floors is the range in which the car 8 travels from the 1st floor to the 5th floor. At this time, in the diagnosis operation, the floors from the first floor to the fifth floor are diagnosed by the car 8 . Also, the floors from the 8th floor to the 12th floor are diagnosed by the counterweight 9 .

As described above, the determination device 17 according to Embodiment 1 includes the response acquisition unit 18 , the damage level storage unit 21 , the damage level determination unit 20 and the diagnosis content determination unit 22 . The response acquisition unit 18 acquires response data. The response data includes seismic response information for each of the plurality of elevator equipment on each of the plurality of floors. The damage level storage unit 21 stores equipment damage levels for each of a plurality of floors. The equipment damage level indicates the damage status of each of a plurality of elevator equipment. The damage level determination unit 20 determines the equipment damage level stored in the damage level storage unit 21 based on the equipment damage level determination criteria and the response data acquired by the response acquisition unit 18 . Equipment damage level criteria are set in advance for each of a plurality of elevator equipment. The diagnosis content determination unit 22 outputs the diagnosis content determined based on the information stored in the damage level storage unit 21 to the diagnostic operation unit 16 . The diagnostic operation unit 16 performs diagnostic operation based on the input diagnostic content.

Thereby, when the building 2 vibrates due to the occurrence of an earthquake, the equipment damage level of each of the plurality of elevator equipment on each of the plurality of floors is determined. Based on the equipment damage level, the diagnostic contents in the diagnostic run are determined before the diagnostic run. Since the contents of the diagnosis are determined according to the damage status of the elevator equipment, the occurrence of secondary damage due to diagnostic operation can be suppressed. In addition, since the equipment damage level of each of the plurality of elevator equipment on each of the plurality of floors is determined, the effects of deformation of the hall doors or guide rails due to deformation between building layers are taken into consideration. In this way, since the detailed damage situation is determined as the influence of the earthquake, the occurrence of secondary damage due to diagnostic operation can be suppressed more reliably. In addition, by determining the detailed damage situation, the determination device 17 can determine possible diagnostic contents with high certainty while suppressing the possibility of occurrence of secondary damage. Therefore, it is not necessary to set an excessive safety margin for the diagnostic operation, so the determination device 17 can increase the restoration rate of the elevator 1 by the automatically performed diagnostic operation. Here, since an earthquake can occur over a wide area, many elevators 1 are affected at the same time. At this time, since the number of specialist engineers who can handle the restoration of the elevator 1 damaged by the earthquake is limited, it may take time to restore the elevator 1 when waiting for the specialist engineers. In such a case, since the recovery rate of the elevator 1 is increased by the diagnostic operation automatically performed by the determination device 17, the elevator 1 can be expected to recover quickly. Moreover, since the contents of the diagnosis are determined according to the damage status of each floor, the diagnostic operation is made more efficient. Therefore, by shortening the time required for the diagnostic operation, the elevator 1 can be expected to be restored more quickly. In this way, the convenience for the users of the elevator 1 after an earthquake has occurred is improved.

Also, the response acquisition unit 18 acquires response data based on the measurement results of earthquake responses from each of the plurality of device response sensors 13 . Each of the plurality of equipment response sensors 13 is arranged on one of the plurality of floors by being attached to one of the plurality of elevator equipment.

The response acquisition unit 18 acquires response data from the information of the earthquake response of the elevator equipment directly measured by the equipment response sensor 13 attached to the elevator equipment. As a result, it is not necessary to estimate the response magnification of the elevator equipment to acquire the response data, so the certainty of determining the equipment damage level is enhanced. In addition, since the estimation of the response magnification is not involved, the reliability of the response data is increased, so the safety margin in the equipment damage level judgment criteria can be reduced. As a result, the determination device 17 can increase the restoration rate of the elevator 1 by the automatically performed diagnostic operation.

Further, the response acquisition unit 18 acquires response data based on measurement results of earthquake responses from each of the multiple floor response sensors 12 . Each of the multiple floor response sensors 12 is arranged on one of the multiple floors.

Typically, a number of elevator devices are provided on each floor of the building 2 . The response acquisition unit 18 acquires response data based on information on the earthquake response measured by each floor response sensor 12 arranged on each floor of the building 2 . Therefore, the response acquisition unit 18 can easily acquire response data using a small number of floor response sensors 12 .

Further, the diagnostic content determination unit 22 determines the range of floors on which the vehicle can be operated based on the equipment damage level. The diagnosis content determination unit 22 outputs the determined floor range to the diagnosis operation unit 16 as information on diagnosis content.

As a result, diagnostic operation is not performed on floors where secondary damage may occur, so the occurrence of secondary damage can be suppressed more reliably. Further, since diagnostic operation is performed only on floors where the possibility of secondary damage is low, at least partial restoration of the elevator 1 can be expected more quickly. This further improves user convenience.

Note that the determination device 17 may be a device external to the control device 14 . A part or all of the determination device 17 such as the response acquisition unit 18, the damage criteria storage unit 19, the damage level determination unit 20, the damage level storage unit 21, and the diagnosis content determination unit 22 are mounted on separate hardware. good too.

FIG. 6 is a configuration diagram of an elevator according to Embodiment 2. FIG.

As shown in FIG. 6, in the building 2, there may be floors on which the floor response sensors 12 are not provided. In the building 2, there may be no floor on which the response sensor 12 for each floor is provided. Alternatively, in the building 2, there may be floors on which no elevator equipment having the equipment response sensor 13 is installed. In the building 2, there may be no floor on which the elevator equipment with the equipment response sensor 13 is installed.

At this time, the response acquisition unit 18 estimates the response based on the seismic response information input from response sensors such as the P-wave sensor 10, the S-wave sensor 11, the car response sensor 13a, or the balance weight response sensor 13b. Get response data by model. The response estimation model is, for example, a model constructed in advance based on history information of response information in past earthquakes, simulation results, or the like. A response estimation model is installed in the response acquisition unit 18 .

As described above, the response acquisition unit 18 of the determination device 17 according to Embodiment 2 acquires response data using a response estimation model. A response estimation model is a model for estimating the seismic response of each of a plurality of elevator equipment on each of a plurality of floors.

Typically, a number of elevator devices are provided on each floor of the building 2 . The response acquisition unit 18 acquires response data by estimating a response estimation model based on, for example, seismic response information measured by a small number of response sensors. Alternatively, the response acquisition unit 18 acquires response data by estimating a response estimation model based on earthquake information from outside such as a seismic observation network. As a result, the response acquisition unit 18 can easily acquire response data using a small number of response sensors.

Embodiment 3.
FIG. 7 is a diagram illustrating an example of earthquake influence determination by the determination device according to the third embodiment.

In this example, the elevator equipment is classified into traveling equipment, landing equipment, or the like according to function, layout, or the like. The running equipment is elevator equipment for running the car 8 or the counterweight 9 . That is, the traveling equipment is elevator equipment that affects the traveling of the car 8 or the counterweight 9, elevator equipment that is affected by the traveling of the car 8 or the counterweight 9, or the like. The guide shoes of the car 8 and the counterweight 9, the guide rails, the brackets, the hoist 6, and the like are examples of traveling equipment. Landing equipment is elevator equipment that becomes part of the non-structural members of the building 2 at the landing, regardless of the running of the car 8 or the counterweight 9 . Hall doors, jambs, and the like are examples of hall equipment.

The damage level storage unit 21 stores equipment damage levels including information on classification of elevator equipment.

In the table of FIG. 7, for the equipment damage levels stored in the damage level storage unit 21, the maximum value of the equipment damage level for each classification of the elevator equipment is shown numerically. For example, the maximum equipment damage level determined for hall equipment on the 7th floor is Lv. 3. That is, on the 7th floor, the equipment damage level of at least one of the hall doors and the hall equipment such as the three-way frame is Lv. 3. Also, the maximum equipment damage level determined for the traveling equipment on the 7th floor is Lv. 1. The maximum equipment damage level determined for the running equipment in the machine room 4 is Lv. 1. The maximum equipment damage level determined for the running equipment in pit 5 is Lv. 1. In this example, Lv. An equipment damage level of 3 has not been determined for any traveling equipment.

At this time, the equipment damage level of each of the plurality of elevator equipment in the machine room 4 or pit 5 is Lv. Since it is 2 or less, the diagnostic content determination unit 22 determines the range of floors that can be operated in the diagnostic operation. Here, if the equipment damage level is Lv. The hall device determined as 3 is on the 7th floor. On the other hand, the equipment damage level for any traveling equipment is Lv. Not rated as 3. Since the landing equipment does not relate to the running of the car 8 or the counterweight 9, the equipment damage level is Lv. If the hall equipment determined as 3 is not used on the floor where the hall equipment is located, the possibility of causing secondary damage due to diagnostic operation is small. Therefore, the diagnostic content determination unit 22 determines the range of operable floors as the range in which the car 8 travels from the 1st floor to the 12th floor. At this time, in the diagnostic operation, the car 8 diagnoses the floors from the 1st floor to the 12th floor. Also, the floors from the 1st floor to the 12th floor are diagnosed by the counterweight 9 .

As described above, the diagnostic content determination unit 22 of the determination device 17 according to Embodiment 3 determines the range of drivable floors based on the equipment damage level indicating the damage status of the traveling equipment. The traveling device is an elevator device related to travel among the plurality of elevator devices. The diagnosis content determination unit 22 outputs the determined floor range to the diagnosis operation unit 16 as information on diagnosis content.

The diagnostic content determination unit 22 determines the diagnostic range based on the equipment damage level of the elevator equipment related to running. For this reason, the diagnostic range is not narrowed by the damage status of the elevator equipment that is not related to running. Therefore, automatic diagnostic operation is performed in a wider diagnostic range. As a result, restoration of the elevator 1 by diagnostic operation can be expected in a wider range.

Embodiment 4.
FIG. 8 is a diagram showing an example of earthquake influence determination by the determination device according to the fourth embodiment.

The damage level storage unit 21 stores floor damage levels. The floor damage level is a damage level indicating the damage status of each elevator 1 on a plurality of floors. The floor damage level is obtained by the damage level storage unit 21, for example. The damage level storage unit 21 obtains the highest damage level among the damage levels stored as equipment damage levels of a plurality of elevator equipment on the same floor as the floor damage level of the floor. The damage level storage unit 21 stores the floor damage level of each floor obtained in this manner.

The diagnosis content determination unit 22 determines the diagnosis content based on the floor damage level stored in the damage level storage unit 21 .

In the table of FIG. 8, floor damage levels are shown numerically. For example, the floor damage level of the 7th floor is Lv. 3. The floor damage level of the machine room 4 obtained based on the equipment damage level of the elevator equipment in the machine room 4 is Lv. 1. That is, the equipment damage level of each of the plurality of elevator equipment in the machine room 4 is Lv. 1 or less. The floor damage level of the machine room 4 obtained based on the equipment damage level of the elevator equipment in the pit 5 is Lv. 2. That is, the equipment damage level of each of the plurality of elevator equipment in pit 5 is Lv. 2 or less.

At this time, the floor damage level of the machine room 4 and the pit 5 is Lv. Since it is 2 or less, the diagnostic content determination unit 22 determines the range of floors that can be operated in the diagnostic operation. In this example, the floor damage level of the 7th floor is Lv. 3, the diagnostic content determining unit 22 determines the range of floors in which both the car 8 and the counterweight 9 do not pass through the seventh floor as the drivable range. Here, the car 8 and the counterweight 9 run symmetrically and in opposite directions with respect to the intermediate floor. Therefore, the range of operable floors is the range in which the car 8 travels from the 1st floor to the 5th floor. At this time, in the diagnosis operation, the floors from the first floor to the fifth floor are diagnosed by the car 8 . Also, the floors from the 8th floor to the 12th floor are diagnosed by the counterweight 9 .

As described above, the damage level storage unit 21 of the determination device 17 according to the fourth embodiment stores the highest equipment damage level among the equipment damage levels of the elevator equipment on the same floor for each of the plurality of floors. The equipment damage level is stored as the floor damage level of the relevant floor.
Further, the diagnostic content determination unit 22 determines the range of floors in which the vehicle can be driven based on the floor damage level. The diagnosis content determination unit 22 outputs the determined floor range to the diagnosis operation unit 16 as information on diagnosis content.

In general, whether or not the elevator can run and the possibility of secondary damage occurring in diagnostic operation is determined by the most severely damaged elevator equipment on each floor. Therefore, the diagnosis content determining unit 22 can more easily determine the diagnosis content based on the floor damage level that represents the damage situation on each floor, regardless of the device damage level of each elevator device.

Note that the floor damage level may be determined by a portion other than the damage level storage unit 21 in the determination device 17, such as the damage level determination unit 20 or the diagnosis content determination unit 22.

Embodiment 5.
9 and 10 are diagrams showing an example of earthquake influence determination by the determination device according to the fifth embodiment.

The diagnosis content determination unit 22 determines a diagnosis method based on the floor damage level stored in the damage level storage unit 21 . As a diagnostic method, the diagnostic content determining unit 22 determines the number of times the car 8 or the counterweight 9 travels on each floor. Here, the number of times of running is, for example, the minimum number of times of running in diagnostic operation.

For example, if the floor damage level is Lv. If it is 1, it is estimated that the earthquake impact on the elevator 1 is minor. At this time, the diagnostic content determination unit 22 determines the number of times of travel on each floor to be one.

In this case, the diagnostic operation unit 16 performs the diagnostic operation so that the car 8 runs on each floor from the first floor to the twelfth floor at least once. Alternatively, since the influence of the earthquake is estimated to be minor, the determination device 17 may restore the elevator 1 to normal operation without causing the diagnostic operation section 16 to perform diagnostic operation.

In FIG. 9, an example of diagnostic contents in the elevator 1 under other conditions is shown. In the table of FIG. 9, floor damage levels are shown numerically. For example, the floor damage level of the 7th floor is Lv. 3. The floor damage level of the 3rd floor is Lv. 2.

In this example, the floor damage level of the machine room 4 and the pit 5 is Lv. Since it is 2 or less, the diagnostic content determination unit 22 determines the range of floors that can be operated in the diagnostic operation. The floor damage level of the 7th floor is Lv. 3, the diagnostic content determining unit 22 determines the range of operable floors to be the range in which the car 8 travels from the first floor to the fifth floor.

The diagnostic content determination unit 22 determines a diagnostic method according to the floor damage level. If the floor damage level of one of the floors is Lv. If the number is 2, the total number of runs in the range of drivable floors is determined to be 2 times.

In this example, the diagnostic operation unit 16 causes the car 8 to travel from the first floor to the fifth floor as the first travel. The diagnostic operation unit 16 causes the car 8 to travel with, for example, a preset speed v as the upper limit of the travel speed. At this time, in the diagnosis operation, the car 8 performs the first diagnosis on the first to fifth floors. Also, the first diagnosis is performed by the counterweight 9 for the eighth to twelfth floors. Thereafter, the diagnostic operation unit 16 causes the car 8 to travel from the fifth floor to the first floor as the second travel. At this time, in the diagnosis operation, the second diagnosis is performed by the car 8 on the floors from the first floor to the fifth floor. Also, the second diagnosis is performed by the counterweight 9 for the eighth to twelfth floors.

FIG. 10 shows another example of determination of the number of times of travel by the diagnosis content determination unit 22 . The damage situation in FIG. 10 is the same as the damage situation in FIG.

If the floor damage level is Lv. For the floor that is 1, the number of times of travel is determined to be one. If the floor damage level is Lv. For the floor that is 2, the number of times of travel is determined to be 2 or more. In this example, the diagnostic content determination unit 22 determines that the floor damage level is Lv. For the 1st, 2nd, 4th, 5th, and 8th to 12th floors that are 1, the number of times of travel is determined to be 1. If the floor damage level is Lv. For the 3rd floor, which is 2, the number of times of travel is determined to be 3 times.

In this example, the diagnostic operation unit 16 causes the car 8 to travel from the first floor to the third floor as the first travel. At this time, in the diagnosis operation, the car 8 performs the first diagnosis on the first to fourth floors. Also, the first diagnosis is performed by the counterweight 9 for the floors from the ninth to the twelfth floors. Thereafter, the diagnostic operation unit 16 causes the car 8 to travel from the fourth floor to the third floor as the second travel. At this time, in the diagnosis operation, the car 8 performs the second diagnosis for the third floor. Here, in diagnostic driving, the diagnostic driving unit 16 may perform driving without diagnosis, for example, to adjust the driving direction or to adjust whether to stop or start the vehicle. In this example, the diagnostic operation unit 16 causes the car 8 to run from the 3rd floor to the 5th floor. Thereafter, the diagnostic operation unit 16 causes the car 8 to run from the fifth floor to the first floor. At this time, in the diagnosis operation, the car 8 performs the third diagnosis for the third floor.

As described above, the diagnosis content determination unit 22 of the determination device 17 according to the fifth embodiment determines the number of times of travel on the floor diagnosed in diagnostic operation according to the floor damage level of the floor. do. The diagnosis content determination unit 22 outputs the determined number of times of travel to the diagnostic operation unit 16 as information on the content of the diagnosis.

The diagnosis contents of the diagnostic operation are set according to the damage situation on each floor. Therefore, the occurrence of secondary damage due to diagnostic operation can be suppressed more reliably. In addition, detection of abnormality in diagnostic operation is performed more reliably. In addition, it is possible to simplify the operation contents of the diagnostic operation or to omit the diagnosis for floors that are estimated to have minor damage. Therefore, diagnostic operation is made more efficient. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Embodiment 6.
FIG. 11 is a diagram showing an example of earthquake influence determination by the determination device according to the sixth embodiment.

The diagnosis content determination unit 22 determines a diagnosis method based on the floor damage level stored in the damage level storage unit 21 . The diagnostic content determining unit 22 determines the traveling speed of the car 8 or the counterweight 9 on each floor as a diagnostic method. Here, the travel speed is, for example, the upper limit speed in diagnostic operation. If the floor damage level is Lv. 1, the running speed is determined to be the speed v1. If the floor damage level is Lv. 2, the running speed is determined to be v2. Here, the speed v1 is a speed faster than the speed v2. In this example, the speed v1 is a speed higher than the driving speed in normal diagnostic driving. Also, the speed v2 is, for example, a speed slower than the traveling speed in normal diagnostic operation. Both the speed v1 and the speed v2 in diagnostic operation are slower than the traveling speed in normal operation.

In FIG. 11, the car 8 has stopped at the 3rd floor before starting the diagnostic operation. At this time, the counterweight 9 is stopped on the tenth floor.

In this example, the diagnostic operation unit 16 causes the car 8 to travel from the third floor to the first floor as the first travel. At this time, the counterweight 9 travels from the 10th floor to the 12th floor. The traveling speed is set to speed v1 between the third floor and the first floor. On the other hand, on the 10th floor, the traveling speed is set to speed v2. Therefore, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v2 in the section from the 10th floor to the 11th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v2 in the section from the third floor to the second floor. Further, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the second floor to the first floor. At this time, the counterweight 9 is caused to travel so that the traveling speed does not exceed the speed v1 in the section from the 11th floor to the 12th floor.

In this way, the diagnostic content determination unit 22 follows the traveling speed determined by the higher floor damage level of the floor damage level of the floor on which the car 8 travels and the floor damage level of the floor on which the counterweight 9 travels. Generate a running speed pattern. The diagnostic operation unit 16 causes the car 8 and the counterweight 9 to travel according to the travel speed pattern generated by the diagnostic content determination unit 22 .

Subsequently, the diagnostic operation unit 16 causes the car 8 to travel from the first floor to the fifth floor as the second travel. At this time, the counterweight 9 travels from the 12th floor to the 8th floor. The diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the first floor to the second floor. At this time, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v1 in the section from the 12th floor to the 11th floor. Further, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v2 in the section from the 11th floor to the 8th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the second floor to the fifth floor.

Thus, in the diagnostic operation, the car 8 performs at least one diagnosis on the first to fifth floors. Also, at least one diagnosis is made by the counterweight 9 for the eighth to twelfth floors.

As described above, the diagnosis content determination unit 22 of the determination device 17 according to Embodiment 6 determines the traveling speed on the floor diagnosed in the diagnostic operation according to the floor damage level of the floor. do. The diagnosis content determination unit 22 outputs the determined traveling speed to the diagnosis operation unit 16 as information on diagnosis content.

The diagnosis contents of the diagnostic operation are set according to the damage situation on each floor. Therefore, the occurrence of secondary damage due to diagnostic operation can be suppressed more reliably. In addition, by diagnosing floors that are estimated to have moderate damage at low running speeds, it is possible to more reliably suppress the occurrence of secondary damage and more reliably detect abnormalities. become. Further, diagnosis operation is made more efficient by diagnosing floors that are presumed to be lightly damaged at a higher running speed than other floors. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Note that the speed v1 may be the same speed as the normal running speed. The speed v2 may be the same speed as the running speed in normal diagnostic operation. The diagnosis content determination unit 22 may determine the running speed from speeds of three or more stages as the running speed. Alternatively, the diagnostic content determination unit 22 may determine the running speed from a continuous range of speeds.

Embodiment 7.
FIG. 12 is a diagram showing an example of earthquake influence determination by the determination device according to the seventh embodiment.
The damage situation in FIG. 12 is the same as the damage situation in FIG.

The diagnosis content determining unit 22 updates the diagnosis content for the subsequent diagnostic operation based on the diagnosis result for the diagnostic operation.

As in the case of FIG. 11, the diagnostic operation unit 16 determines the higher floor damage level of the floor damage level of the floor on which the car 8 travels and the floor damage level of the floor on which the counterweight 9 travels. The car 8 and the counterweight 9 are run according to the running speed. That is, the diagnostic operation unit 16 causes the car 8 to travel from the third floor to the first floor as the first travel. The diagnostic driving unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v2 in the section from the 10th floor to the 11th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v2 in the section from the third floor to the second floor. Further, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the second floor to the first floor. At this time, the counterweight 9 is caused to travel so that the traveling speed does not exceed the speed v1 in the section from the 11th floor to the 12th floor.

If no abnormality is detected in the first run, the diagnostic content determination unit 22 updates the running speed. In this example, the running speed on the 10th floor is updated to v1. The diagnostic operation unit 16 performs diagnostic operation based on the updated diagnostic content.

Subsequently, the diagnostic operation unit 16 causes the car 8 to travel from the first floor to the fifth floor as the second travel. At this time, the counterweight 9 travels from the 12th floor to the 8th floor. Based on the updated diagnostic method, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v1 in the section from the 12th floor to the 10th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the first floor to the third floor. Further, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v2 in the section from the 10th floor to the 8th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the third floor to the fifth floor.

If no abnormality is detected in the second run, the diagnostic content determination unit 22 updates the running speed. In this example, the running speed on the 9th floor is updated to v1. Note that the diagnosis content determination unit 22 may update the number of times of travel based on the diagnosis result of the diagnostic operation. That is, the diagnostic content determination unit 22 may increase or decrease the number of times of travel. Further, even when no abnormality is detected, the diagnosis content determination unit 22 does not have to update the traveling speed for any floor. The diagnosis content determination unit 22 may update the running speed to a lower speed when a sign of abnormality is detected even when no abnormality is detected.

The diagnostic operation unit 16 causes the car 8 to travel from the fifth floor to the first floor as the third travel. At this time, the counterweight 9 travels from the 8th floor to the 12th floor. Based on the updated diagnostic method, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v2 in the section from the 8th floor to the 9th floor. At this time, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v2 in the section from the fifth floor to the fourth floor. Further, the diagnostic operation unit 16 causes the car 8 to travel so that the traveling speed does not exceed the speed v1 in the section from the fourth floor to the first floor. At this time, the diagnostic operation unit 16 causes the counterweight 9 to travel so that the traveling speed does not exceed the speed v1 in the section from the 9th floor to the 12th floor.

As described above, the diagnostic content determination unit 22 of the determination device 17 according to the seventh embodiment determines the diagnosis content when the floor once diagnosed in the diagnostic operation is diagnosed again in the diagnostic operation. is updated based on the results already diagnosed for that floor. The diagnostic content determination unit 22 outputs the updated diagnostic content to the diagnostic operation unit 16 .

The diagnosis contents of the diagnostic driving are updated according to the result of the diagnosis of the diagnostic driving on each floor. Here, the diagnosis result used for updating the diagnosis content is the provisional diagnosis result before the diagnostic operation is completed. In this way, since the contents of the diagnosis are updated based on the results of the provisional diagnosis, diagnostic driving is performed with the contents of the diagnosis more suitable for the damage situation. Therefore, it is possible to more reliably suppress the occurrence of secondary damage and to more reliably detect anomalies on floors that are estimated to be moderately damaged. In addition, diagnostic operation can be made more efficient for floors that are estimated to have minor damage. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Embodiment 8.
FIG. 13 is a diagram showing an example of determination of earthquake influence by the determination device according to the eighth embodiment.

The diagnosis content determination unit 22 determines a diagnosis method based on information stored in the damage level storage unit 21 . The diagnosis content determining unit 22 determines the door opening/closing speed for each floor as a diagnostic method. Here, the door opening/closing speed is, for example, the upper limit speed when the landing door opens/closes. In this example, the diagnostic content determination unit 22 determines the door opening/closing speed based on the equipment damage level of the hall door. If the equipment damage level of the hall door is Lv. 1, the door opening/closing speed is determined to be the speed vd1. If the equipment damage level of the hall door is Lv. 2, the door opening/closing speed is determined to be the speed vd2. In this example, the speed vd1 is a speed higher than the door opening/closing speed in normal diagnostic operation. Also, the speed vd2 is slower than the door opening/closing speed in normal diagnostic operation, for example. Both the speed v1 and the speed v2 in diagnostic operation are slower than the door opening/closing speed in normal operation.

In the table of FIG. 13, the equipment damage levels of the hall doors stored in the damage level storage unit 21 are indicated by numerical values. For example, the equipment damage level of the hall door on the 4th floor is Lv. 2. In this example, the diagnostic operation unit 16 diagnoses opening/closing of the doors so that the door opening/closing speed does not exceed the speed vd1 when the car 8 is stopped on the 1st to 3rd floors and the 5th floor. Further, the diagnosis operation unit 16 diagnoses opening/closing of the door so that the door opening/closing speed does not exceed the speed vd2 when the car 8 is stopped on the fourth floor. On floors from the sixth floor to the twelfth floor on which the car 8 does not run, opening/closing of the door is not diagnosed regardless of the device damage level of the landing door.

As described above, the diagnosis content determination unit 22 of the determination device 17 according to the eighth embodiment has the damage level storage unit 21 store the door opening/closing speed on the floor where door opening/closing is diagnosed in the diagnostic operation. decision based on the information available. The diagnosis content determination unit 22 outputs the determined door opening/closing speed to the diagnosis operation unit 16 as information on the content of diagnosis.

The diagnosis contents of the diagnostic operation are set according to the damage situation on each floor. Therefore, the occurrence of secondary damage due to diagnostic operation can be suppressed more reliably. In addition, for floors where it is estimated that damage caused by door opening/closing is moderate, diagnosis is performed at a slow door opening/closing speed to more reliably suppress the occurrence of secondary damage and detect abnormalities. be able to do it for sure. Further, diagnosis operation is made more efficient by diagnosing floors in which door opening/closing damage is estimated to be minor at a higher opening/closing speed than other floors. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Note that the speed vd1 may be the same speed as the normal door opening/closing speed. The speed vd2 may be the same speed as the door opening/closing speed in normal diagnostic operation. The diagnosis content determination unit 22 may determine the door opening/closing speed from three or more levels of door opening/closing speeds. Alternatively, the diagnostic content determination unit 22 may determine the door opening/closing speed from a continuous speed range.

Further, the diagnosis content determination unit 22 may determine the door opening/closing speed based on the floor damage level. Further, the diagnostic content determination unit 22 may determine the door opening/closing speed based on the equipment damage level of elevator equipment other than the hall door, such as jambs. Further, the diagnosis content determination unit 22 may update the diagnosis content regarding the door opening/closing speed as the diagnosis content based on the diagnosis result in the diagnostic operation.

Embodiment 9.
FIG. 14 is a diagram showing an example of determination of earthquake influence by the determination device according to the ninth embodiment.

The diagnosis content determination unit 22 determines a diagnosis method based on information stored in the damage level storage unit 21 . As a diagnostic method, the diagnostic content determination unit 22 determines conditions for detecting anomalies in diagnostic operation based on, for example, equipment damage levels or floor damage levels. The abnormality detection condition is, for example, a threshold for a measured value used for abnormality determination in diagnostic operation. Here, the measured value used for abnormality determination is, for example, the torque value of the hoisting machine 6, the acceleration value of the car 8, or the like.

In FIG. 14, the horizontal axis of the graph represents the elapsed time from the occurrence of the earthquake. The vertical axis of the graph represents diagnostic target values such as measured values used for abnormality detection in diagnostic operation.

The diagnostic operation unit 16 detects an abnormality when conditions for detecting an abnormality are satisfied in the diagnostic operation. In this example, the diagnostic operation unit 16 sets the abnormality detection condition that the diagnostic target value exceeds a set threshold value. In the diagnostic operation unit 16, a threshold value Th2 is set as an initial value for conditions for detecting an abnormality. The threshold Th2 is a value preset based on, for example, the strength design of elevator equipment such as the hoisting machine 6 or the car 8 to which the diagnosis target value corresponds.

After the determination by the damage level determination unit 20, the diagnosis content determination unit 22 determines the abnormality detection conditions as the diagnosis content. The diagnosis content determination unit 22 determines that the equipment damage level of the elevator equipment corresponding to the diagnosis target value is Lv. For the floor that is 1, the threshold for the abnormality detection condition is determined as Th1. Here, the threshold Th1 is a value raised from the threshold Th2. In other words, the diagnostic content determination unit 22 relaxes the conditions for abnormality detection. There is a possibility that fluctuations in diagnostic target values are not due to the effects of earthquakes on floors that are presumed to have minor damage. At this time, by relaxing the conditions for abnormality detection, erroneous detection of a change in a diagnosis target value, which is not originally abnormal, as an abnormality can be prevented.

After the diagnostic content is determined, the diagnostic operation section 16 starts the diagnostic operation. The diagnostic operation unit 16 detects an abnormality when the diagnosis target value exceeds the originally set threshold value Th2 on the floor where the condition for abnormality detection has not been raised. On the other hand, on the floor for which the abnormality detection condition has been raised, if the diagnosis target value exceeds the threshold Th2 but does not exceed the raised threshold Th1 as shown in FIG. Not detected.

It should be noted that the diagnosis content determining unit 22 determines that the equipment damage level of the elevator equipment corresponding to the diagnosis target value is Lv. 2, the threshold value for the abnormality detection condition may be determined to be a value lower than Th2. In other words, the diagnostic content determination unit 22 may set stricter conditions for abnormality detection.

As described above, the diagnostic content determination unit 22 of the determination device 17 according to the ninth embodiment determines the conditions for abnormality detection in diagnostic operation based on the information stored in the damage level storage unit 21 . The diagnostic content determination unit 22 outputs the determined abnormality detection conditions to the diagnostic operation unit 16 as information on diagnostic content.

The diagnosis contents of the diagnostic operation are set according to the damage situation on each floor. Therefore, the occurrence of secondary damage due to diagnostic operation can be suppressed more reliably. In addition, by making the conditions for abnormality detection more stringent for floors that are estimated to be moderately damaged, it is possible to more reliably suppress the occurrence of secondary damage and more reliably detect abnormalities. become. Further, by diagnosing floors in which damage is estimated to be minor under conditions for detecting anomalies that are less severe than those for other floors, fluctuations in diagnostic target values are allowed. Therefore, erroneous detection of abnormalities is suppressed, and diagnostic operation is made more efficient. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Note that the diagnostic content determination unit 22 may determine the conditions for abnormality detection based on the floor damage level. Further, the diagnosis content determination unit 22 may update the abnormality detection condition as the diagnosis content based on the diagnosis result of the diagnostic operation.

Embodiment 10.
FIG. 15 is a diagram showing an example of earthquake influence determination by the determination device according to the tenth embodiment.

The diagnosis content determination unit 22 determines the diagnosis content based on the swing amount of the rope body of the elevator 1 . The rope bodies of the elevator 1 are, for example, main ropes 7, balance ropes, governor ropes or control cables. The swing amount of the rope body is acquired by the device response sensor 13, for example. Alternatively, the swing amount of the rope body may be obtained by a response estimation model. The amount of swaying of the rope body is, for example, the amplitude of lateral swaying in the horizontal direction.

It is presumed that when the amount of swaying of the rope body is small, the rope body does not get caught on equipment around it. Therefore, when the amount of swaying of the rope body is smaller than a preset reference value, there is little possibility that secondary damage will occur due to diagnostic operation. On the other hand, when the amount of swaying of the rope body is large, there is a possibility that the rope body may be caught in equipment around the rope body. Therefore, when the swing amount of the rope body is larger than the reference value, the diagnostic content determination unit 22 reduces the traveling speed in the generated traveling speed pattern by a certain ratio such as 10%.

The diagnostic operation unit 16 performs diagnostic operation according to the diagnostic content determined by the diagnostic content determination unit 22 based on the swing amount of the rope body.

As described above, the diagnosis content determination unit 22 of the determination device 17 according to the tenth embodiment determines the diagnosis content based on the swing amount of the rope body of the elevator 1 . The diagnostic content determination unit 22 outputs the determined diagnostic content to the diagnostic operation unit 16 .

If the swing amount is large, the rope body may get caught on peripheral equipment. At this time, the entanglement of the rope may cause secondary damage due to diagnostic operation. Corresponding to this, the diagnostic content of the diagnostic operation is set according to the swing amount of the rope body, so the occurrence of secondary damage due to the diagnostic operation can be suppressed more reliably.

It should be noted that, when the swing amount of the rope body is smaller than the reference value, the diagnostic content determining unit 22 may increase the traveling speed in the generated traveling speed pattern by a certain ratio such as 10%. As a result, the time required for diagnostic operation is shortened, so that the elevator 1 can be expected to be restored sooner.

Further, when the swing amount of the rope body is larger than the reference value, the diagnostic content determination unit 22 may tighten the abnormality detection conditions by, for example, lowering the threshold value. Alternatively, when the swing amount of the rope body is greater than the reference value, the diagnosis content determination unit 22 may increase the number of times of running.

The determination device according to the present disclosure can be applied to elevators.
