[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-173388 Summary of the Invention [Problem to be solved by the invention]

[0004] In addition to the Earthquake Early Warning, other information about earthquakes may be announced. For example, such information about earthquakes includes emergency information about the Nankai Trough earthquake. The elevator device described in Patent Document 1 can respond to the Earthquake Early Warning, but cannot perform appropriate control in response to, for example, the emergency information about the Nankai Trough earthquake.

[0006] An elevator system according to the present disclosure includes a first determination unit that determines whether a first earthquake emergency has been announced, which will be followed by a second earthquake emergency, a second determination unit that determines whether the second earthquake emergency has been announced, and an operation control unit that, when the first determination unit determines that the first earthquake emergency has been announced and there are no calls for the car, performs standby operation to keep the car on standby at a standby position in preparation for the occurrence of an earthquake.When the second determination unit determines that the second earthquake emergency has been announced, the operation control unit pauses the car if the announced second earthquake emergency evaluates that the likelihood of a major earthquake occurring has increased, and ends standby operation if the announced second earthquake emergency does not evaluate that the likelihood of a major earthquake occurring has increased.

[0007] An elevator system according to the present disclosure includes a first determination unit that determines whether a first earthquake emergency has been announced, which will be followed by a second earthquake emergency, a second determination unit that determines whether the second earthquake emergency has been announced, and an operation control unit that, when the first determination unit determines that the first earthquake emergency has been announced and there are no calls for the car, performs standby operation to keep the car on standby at a standby position in preparation for an earthquake. When the second determination unit determines that the second earthquake emergency has been announced, the operation control unit pauses the car if the announced second earthquake emergency evaluates that vigilance against a major earthquake is required, continues standby operation if the announced second earthquake emergency evaluates that caution against a major earthquake is required, and ends standby operation if the announced second earthquake emergency evaluates that neither vigilance nor caution against a major earthquake is required.

[0008] An elevator system according to the present disclosure includes a first determination unit that determines whether a first earthquake emergency has been announced, which will be followed by a second earthquake emergency, a second determination unit that determines whether the second earthquake emergency has been announced, and an operation control unit that, when the first determination unit determines that the first earthquake emergency has been announced, performs earthquake emergency operation to prevent equipment damage or entrapment in the car due to an earthquake. When the second determination unit determines that the second earthquake emergency has been announced, the operation control unit suspends the car if the announced second earthquake emergency evaluates that the likelihood of a major earthquake occurring has increased, and terminates earthquake emergency operation if the announced second earthquake emergency does not evaluate that the likelihood of a major earthquake occurring has increased.

[0009] An elevator system according to the present disclosure includes a first determination unit that determines whether a first earthquake emergency has been announced, which will be followed by a second earthquake emergency, a second determination unit that determines whether the second earthquake emergency has been announced, and an operation control unit that, when the first determination unit determines that the first earthquake emergency has been announced, performs earthquake emergency operation to prevent equipment damage or entrapment in the car due to an earthquake.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The following detailed description will be given with reference to the drawings. Duplicate descriptions will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0013] Embodiment 1 FIG. 1 is a diagram showing an example of an elevator apparatus 1 according to a first embodiment. The elevator apparatus 1 includes a car 2 and a counterweight 3. The car 2 moves up and down in a hoistway 4. The hoistway 4 is a vertically extending space formed in a building. As an example, a landing 5 where the car 2 can stop is provided on each floor of the building. The car 2 and the counterweight 3 are suspended from the hoistway 4 by a rope 6. FIG. 1 shows an example of an elevator apparatus 1 using a 1:1 roping system.

[0014] The rope 6 is wound around a drive sheave 8 of a hoisting machine 7. The hoisting machine 7 is controlled by a control device 9. When the drive sheave 8 rotates, the rope 6 moves in a direction corresponding to the direction in which the drive sheave 8 rotates. The car 2 moves up or down the hoistway 4 depending on the direction in which the rope 6 moves. The counterweight 3 moves in the direction opposite to the direction in which the car 2 moves. The hoisting machine 7 is an example of a device that drives the car 2. The movement of the car 2 is controlled by the control device 9.

[0015] 1 shows an example in which the hoisting machine 7 and the control device 9 are installed in a machine room 10 above the hoistway 4. The hoisting machine 7 and the control device 9 may also be installed in the hoistway 4. The hoisting machine 7 may be provided at the top of the hoistway 4 or in a pit in the hoistway 4.

[0016] A communication device 11 is connected to the control device 9. The communication device 11 communicates with external devices via a network 12. The external devices may include a terminal provided in an information center 13. For example, the information center 13 is operated by a management company that manages the elevator device 1. The external devices may include a server managed by the management company. The external devices may also include other devices.

[0017] The communication device 11 receives emergency earthquake information. As an example, the communication device 11 receives emergency earthquake information from a public institution such as the Japan Meteorological Agency. The communication device 11 may receive emergency earthquake information from the information center 13. The communication device 11 may receive emergency earthquake information from other facilities, etc. The emergency earthquake information is different from the so-called emergency earthquake warning. The emergency earthquake information will be described in detail below.

[0018] Emergency earthquake information includes first and second earthquake information. First earthquake information is issued when an abnormal phenomenon is observed in a specific region or sea area, and an investigation has begun or is ongoing to determine whether the phenomenon is related to a large-scale earthquake in that region.

[0019] The second earthquake emergency information is released after the first earthquake emergency information is released. In other words, when the first earthquake emergency information is released, the second earthquake emergency information is always released afterwards. For example, the second earthquake emergency information may be released one to two hours after the first earthquake emergency information is released. The second earthquake emergency information is information released about the results of an investigation into an observed abnormal phenomenon.

[0020] The so-called Nankai Trough Earthquake Emergency Information is one example of such earthquake emergency information. In the Nankai Trough Earthquake Emergency Information, the first earthquake emergency information is announced as Nankai Trough Earthquake Emergency Information (Investigation Underway). In addition, the second earthquake emergency information is announced as Nankai Trough Earthquake Emergency Information (Massive Earthquake Alert), Nankai Trough Earthquake Emergency Information (Massive Earthquake Caution), or Nankai Trough Earthquake Emergency Information (Investigation Completed).

[0021] For example, if an investigation into observed abnormal phenomena indicates that the likelihood of a Nankai Trough earthquake occurring is relatively higher than normal, then an Emergency Nankai Trough Earthquake Information (Massive Earthquake Alert) or Emergency Nankai Trough Earthquake Information (Massive Earthquake Caution) will be issued. If it is not determined that the likelihood of a Nankai Trough earthquake occurring is relatively higher than normal, then an Emergency Nankai Trough Earthquake Information (Investigation End) will be issued. Specifically, if the observed abnormal phenomena correspond to a specific event, then an Emergency Nankai Trough Earthquake Information (Massive Earthquake Alert) will be issued. If the observed abnormal phenomena correspond to a specific other event, then an Emergency Nankai Trough Earthquake Information (Massive Earthquake Caution) will be issued. If the observed abnormal phenomena do not correspond to either the specific event or the specific other circumstances, then an Emergency Nankai Trough Earthquake Information (Investigation End) will be issued.

[0022] In the example shown in this embodiment, the emergency earthquake information includes not only official information released by public institutions, but also information issued by a person in charge at information center 13, for example, in response to the official information, as information corresponding to the official information.

[0023] FIG. 2 is a diagram showing an example of the control device 9. The control device 9 includes a first determination unit 20, an operation control unit 21, and a second determination unit 22. The control device 9 may further include an alarm control unit 23. The alarm control unit 23 controls the alarm 14. The alarm 14 may be a display or a speaker. Other alarm means may be provided as the alarm 14. The alarm 14 may be provided at each landing 5. The alarm 14 may be provided in the car 2. The alarm 14 may be provided at both each landing 5 and the car 2.

[0024] The functions of the elevator device 1 will be described in detail below with reference to Fig. 3. Fig. 3 is a flowchart showing an example of the operation of the elevator device 1. Specifically, Fig. 3 shows the operation flow of the control device 9.

[0025] In the control device 9, the first determination unit 20 determines whether or not a first earthquake emergency notice has been issued (S101). In the following, a detailed explanation will be given of an example in which the earthquake emergency notice is a Nankai Trough earthquake emergency notice. For example, if the Japan Meteorological Agency has not issued a Nankai Trough earthquake emergency notice (under investigation), the determination in S101 is No.

[0026] If S101 returns No, the operation control unit 21 performs normal operation (S102). In normal operation, when a call for car 2 is registered, the operation control unit 21 causes car 2 to respond to the registered call. In normal operation, when there is no call for car 2, the operation control unit 21 may cause car 2 to wait at the first waiting position. The first waiting position is preferably a stopping position at the hall 5. As an example, the first waiting position is a stopping position on the lobby floor. The first waiting position may be set so as to reduce waiting time for users. Operational efficiency may be taken into consideration when setting the first waiting position. Energy saving may be taken into consideration when setting the first waiting position.

[0027] When the communication device 11 receives the first earthquake emergency information during normal operation, the result of S101 is Yes. That is, the first determination unit 20 determines that the Nankai Trough earthquake emergency information (under investigation) has been announced. When the result of S101 is Yes, the operation control unit 21 performs standby operation (S103).

[0028] In standby operation, when a call for car 2 is registered, the operation control unit 21 causes car 2 to respond to the registered call. Also, in standby operation, when there is no call for car 2, car 2 is caused to wait at the second standby position. The second standby position does not have to be the stopping position of the hall 5. The second standby position may be the stopping position of the hall 5. The second standby position is a position to prepare for the occurrence of an earthquake.

[0029] As an example, the second standby position is a position different from the first standby position. The second standby position may be set based on a non-resonance position of the building in which the elevator apparatus 1 is installed. The non-resonance position is a position where the amplitude of vibrations is relatively small when the building resonates with earthquake vibrations. The second standby position may be set based on a position where long objects installed in the elevator apparatus 1 are less susceptible to earthquake vibrations when the car 2 stops.

[0030] When standby operation is started in S103, the notification control unit 23 causes the alarm 14 to notify that standby operation is being performed (S104). The notification in S104 is continued while standby operation is being performed by the operation control unit 21.

[0031] Furthermore, if S101 is determined to be Yes, the second determination unit 22 determines whether or not a second earthquake emergency information has been issued (S105). For example, if the Japan Meteorological Agency has not issued any of the Nankai Trough Earthquake Emergency Information (Massive Earthquake Alert), Nankai Trough Earthquake Emergency Information (Massive Earthquake Caution), and Nankai Trough Earthquake Emergency Information (Investigation End), the determination in S105 is No. If S105 is determined to be No, the operation control unit 21 continues standby operation (S103).

[0032] When the communication device 11 receives the second earthquake emergency information while the vehicle is in standby operation, the result of S105 is determined as Yes. That is, the second determination unit 22 determines that the second earthquake emergency information has been announced. When the second determination unit 22 determines that the second earthquake emergency information has been announced, the second determination unit 22 then identifies the content of the second earthquake emergency information.

[0033] Specifically, the second determination unit 22 first determines whether the published second earthquake emergency information is Nankai Trough earthquake emergency information (major earthquake alert) or not (S106). If the second earthquake emergency information published by the Japan Meteorological Agency is Nankai Trough earthquake emergency information (major earthquake alert), a Yes determination is made in S106. If a Yes determination is made in S106, the operation control unit 21 suspends the car 2 (S107). That is, the operation control unit 21 suspends the car 2 if the published second earthquake emergency information evaluates that alert to a major earthquake is required.

[0034] In S107, no call is registered for car 2. Even if a call is registered for car 2, in S107, the operation control unit 21 does not cause car 2 to respond to the registered call. In S107, car 2 stops with the door open or closed. In S107, the light on car 2 may be turned off.

[0035] When the car 2 is put to a halt in S107, the notification control unit 23 causes the annunciator 14 to notify that the car 2 is being halted (S108). The notification in S108 continues while the car 2 is halted.

[0036] If the announced second earthquake emergency information is not Nankai Trough earthquake emergency information (major earthquake alert), the determination in S106 is No. If the determination in S106 is No, the second determination unit 22 next determines whether the announced second earthquake emergency information is Nankai Trough earthquake emergency information (major earthquake alert) or not (S109).

[0037] If the second earthquake emergency information issued by the Japan Meteorological Agency is Nankai Trough earthquake emergency information (major earthquake warning), a Yes determination is made in S109. If a Yes determination is made in S109, the operation control unit 21 continues standby operation (S110). That is, if the second earthquake emergency information issued is evaluated as requiring caution against a major earthquake, the operation control unit 21 continues standby operation.

[0038] Even after the standby operation is continued in S110, the notification control unit 23 causes the alarm 14 to notify that the standby operation is being performed (S111). The notification in S111 continues while the standby operation is being performed by the operation control unit 21.

[0039] If the announced second earthquake emergency information is not Nankai Trough earthquake emergency information (major earthquake warning), the result of S109 is determined to be No. If the result of S109 is determined to be No, the second determination unit 22 next determines whether the announced second earthquake emergency information is Nankai Trough earthquake emergency information (investigation completed) (S112).

[0040] If the second earthquake emergency information released by the Japan Meteorological Agency is Nankai Trough earthquake emergency information (survey completed), a Yes determination is made in S112. If a Yes determination is made in S112, the operation control unit 21 ends the standby operation started in S103 (S113). That is, the operation control unit 21 ends the standby operation unless the released second earthquake emergency information evaluates that the possibility of a huge earthquake occurring has increased. After ending the standby operation in S113, the operation control unit 21 may start normal operation.

[0041] Furthermore, if the determination in S112 is Yes, the notification control unit 23 ends the notification that standby operation is being performed, which was started in S104 (S114).

[0042] In the example shown in this embodiment, when the first determination unit 20 determines that the first earthquake emergency information has been issued, standby operation is performed. Thereafter, when the second determination unit 22 determines that the second earthquake emergency information has been issued, if the second earthquake emergency information evaluates that vigilance against a huge earthquake is required, the car 2 is put into a halt. Furthermore, if the second earthquake emergency information evaluates that caution against a huge earthquake is required, standby operation is continued. If the second earthquake emergency information does not evaluate that vigilance against a huge earthquake or caution is required, standby operation is terminated. Therefore, the elevator device 1 can perform appropriate control in accordance with the earthquake emergency information.

[0043] In the present embodiment, an example has been described in which different operations are performed when the determination in S106 is Yes, when the determination in S109 is Yes, and when the determination in S112 is Yes. As another example, the same operation may be performed when the determination in S106 is Yes and when the determination in S109 is Yes.

[0044] 3, if the determination in S109 is Yes, the process may proceed to S107. In such a case, the process shown in S110 and the process shown in S111 may not be performed. That is, in this example, when the second determination unit 22 determines that the second earthquake emergency information has been issued, if the issued second earthquake emergency information evaluates that the possibility of a huge earthquake occurring is relatively higher than usual, the process shown in S107 and the process shown in S108 are performed. If the issued second earthquake emergency information does not evaluate that the possibility of a huge earthquake occurring is relatively higher than usual, the process shown in S113 and the process shown in S114 are performed.

[0045] The following describes other functions that can be adopted by the elevator system 1. If possible, the elevator system 1 may adopt a combination of the following functions.

[0046] As shown in Fig. 2, the control device 9 may further include a cancellation unit 24. The cancellation unit 24 has a function of canceling the standby operation started in S103. As an example, when a cancellation request signal is input to the control device 9, the cancellation unit 24 cancels the standby operation started in S103. When the standby operation is canceled by the cancellation unit 24, the operation control unit 21 may perform normal operation. Note that when the standby operation is canceled by the cancellation unit 24, the processes shown in S105 to S114 in Fig. 3 are not performed.

[0047] If the elevator device 1 is provided with the release unit 24, the owner or manager of the building in which the elevator device 1 is provided can release the standby operation after the first earthquake emergency information is issued, depending on the situation. As one example, a release request signal may be input to the control device 9 by operating a switch provided in the building's management room. Alternatively, a release request signal may be input to the control device 9 by performing a specific operation on a terminal owned by the building owner. The method for inputting a release request signal to the control device 9 is not limited to these examples.

[0048] Incidentally, even if the control device 9 is provided with the cancellation unit 24, if standby operation is continued as a result of a determination of Yes in S109, the subsequent standby operation does not need to be cancelled by the cancellation unit 24. That is, after a determination of Yes in S109, the standby operation continues even if a cancellation request signal is input to the control device 9.

[0049] As another example, as shown in FIG. 2, the control device 9 may further include a pause unit 25. The pause unit 25 has a function of canceling the standby operation started in S103 and pausing the car 2. As an example, when a pause request signal is input to the control device 9, the pause unit 25 cancels the standby operation started in S103. When the standby operation is canceled by the pause unit 25, the operation control unit 21 pauses the car 2. At this time, the notification control unit 23 may notify the fact that the car 2 is paused from the alarm 14. Note that when the standby operation is canceled by the pause unit 25, the processes shown in S105 to S114 in FIG. 3 are not performed.

[0050] If the suspension unit 25 is provided, the owner or manager of the building in which the elevator device 1 is installed can cancel the standby operation after the first earthquake emergency information is issued depending on the situation. Any method may be used to input the suspension request signal to the control device 9.

[0051] Fig. 4 is a flowchart showing another example of the operation of the elevator device 1. The processes shown in S201 to S202 in Fig. 4 are similar to the processes shown in S101 to S102 in Fig. 3. For example, if the communication device 11 receives the first earthquake emergency information during normal operation, a determination of Yes is made in S201.

[0052] If S201 returns Yes, the operation control unit 21 performs earthquake emergency operation (S203). Earthquake emergency operation is an operation for suppressing damage to equipment due to an earthquake or for suppressing people being trapped in car 2. In earthquake emergency operation, specific restrictions are imposed on the control of car 2 that are not imposed in normal operation. In earthquake emergency operation, when a call for car 2 is registered, the operation control unit 21 causes car 2 to respond to the registered call to the extent that it can respond.

[0053] As an example, during earthquake special operation, control may be performed to prevent car 2 from entering the express zone. That is, the operation control unit 21 prohibits car 2 from entering the express zone during earthquake special operation. The express zone is a section of the section in which car 2 can travel that includes floors on which no hall 5 is provided. For example, if car 2 stops on the first floor and floors 10-15 of a building, and no hall 5 is provided on floors 2-9, the section from floor 2 to 9 is the express zone. In this example, during earthquake special operation, service is provided that stops on floors 10-15. During earthquake special operation, car 2 does not enter the express zone, so car 2 does not move downward from the 10th floor. That is, during earthquake special operation, car 2 does not stop on the first floor.

[0054] As another example, during earthquake temporary operation, a speed limit may be imposed on car 2. During earthquake temporary operation, other limits may be imposed.

[0055] When the earthquake temporary operation is started in S203, the notification control unit 23 causes the alarm 14 to notify that the earthquake temporary operation is being performed (S204). The notification in S204 continues while the operation control unit 21 is performing the earthquake temporary operation.

[0056] The processing shown in S205 to S209 in Fig. 4 is the same as the processing shown in S105 to S109 in Fig. 3. If the determination in S205 is No, the operation control unit 21 continues the earthquake temporary operation (S203).

[0057] Furthermore, if the second determination unit 22 determines that second earthquake emergency information has been issued (Yes in S205) and the second earthquake emergency information is Nankai Trough earthquake emergency information (major earthquake warning), then Yes is determined in S209. If Yes is determined in S209, the operation control unit 21 continues earthquake emergency operation (S210). That is, if the issued second earthquake emergency information evaluates that caution is required for a major earthquake, the operation control unit 21 continues earthquake emergency operation.

[0058] Even after the standby operation continues in S210, the notification control unit 23 causes the alarm 14 to notify that the earthquake temporary operation is being performed (S211). The notification in S211 continues while the operation control unit 21 is performing the earthquake temporary operation.

[0059] The process shown in S212 in Fig. 4 is the same as the process shown in S112 in Fig. 3. If the determination in S212 is Yes, the operation control unit 21 ends the earthquake special operation started in S203 (S213). That is, the operation control unit 21 ends the earthquake special operation unless the published second earthquake special information indicates an increased possibility of a huge earthquake occurring. After ending the earthquake special operation in S213, the operation control unit 21 may start normal operation.

[0060] Furthermore, if the determination in S212 is Yes, the notification control unit 23 ends the notification that earthquake special operation is being performed, which was started in S204 (S214).

[0061] In the example shown in FIG. 4, when the first determination unit 20 determines that the first earthquake emergency information has been issued, earthquake emergency operation is performed. Thereafter, when the second determination unit 22 determines that the second earthquake emergency information has been issued, if the second earthquake emergency information evaluates that vigilance against a huge earthquake is required, car 2 is suspended. Furthermore, if the second earthquake emergency information evaluates that caution against a huge earthquake is required, earthquake emergency operation is continued. If the second earthquake emergency information does not evaluate that vigilance against a huge earthquake or caution is required, earthquake emergency operation is terminated. Therefore, the elevator device 1 can perform appropriate control in accordance with the earthquake emergency information.

[0062] As in the example shown in FIG. 3, in the example shown in FIG. 4, the same operation may be performed when the determination in S206 is Yes and when the determination in S209 is Yes.

[0063] 4, if the determination in S209 is Yes, the process may proceed to S207. In such a case, the process shown in S210 and the process shown in S211 may not be performed. That is, in this example, when the second determination unit 22 determines that the second earthquake emergency information has been issued, if the issued second earthquake emergency information evaluates that the possibility of a huge earthquake occurring is relatively higher than usual, the process shown in S207 and the process shown in S208 are performed. If the issued second earthquake emergency information does not evaluate that the possibility of a huge earthquake occurring is relatively higher than usual, the process shown in S213 and the process shown in S214 are performed.

[0064] In the example shown in Fig. 4, the control device 9 may further include a cancellation unit 24. In the example shown in Fig. 4, the cancellation unit 24 has a function of canceling the earthquake temporary operation started in S203. As an example, when a cancellation request signal is input to the control device 9, the cancellation unit 24 cancels the earthquake temporary operation started in S203. When the earthquake temporary operation is canceled by the cancellation unit 24, the operation control unit 21 may perform normal operation. Note that when the earthquake temporary operation is canceled by the cancellation unit 24, the processes shown in S205 to S214 in Fig. 4 are not performed.

[0065] Even if the control device 9 is equipped with the cancellation unit 24, if earthquake temporary operation is continued by determining Yes in S209, the earthquake temporary operation thereafter does not need to be canceled by the cancellation unit 24. In other words, after determining Yes in S209, earthquake temporary operation continues as is even if a cancellation request signal is input to the control device 9.

[0066] Furthermore, in the example shown in FIG. 4, the control device 9 may further include a pause unit 25. In this example, the pause unit 25 has the function of canceling the earthquake temporary operation started in S203 and pausing the car 2. As an example, when a pause request signal is input to the control device 9, the pause unit 25 cancels the earthquake temporary operation started in S203. When the earthquake temporary operation is canceled by the pause unit 25, the operation control unit 21 pauses the car 2. At this time, the notification control unit 23 may notify the fact that the car 2 is paused from the alarm 14. Note that when the earthquake temporary operation is canceled by the pause unit 25, the processing shown in S205 to S214 in FIG. 4 is not performed.

[0067] 5 is a diagram showing an example of hardware resources of the control device 9. The control device 9 includes, as hardware resources, a processing circuit 30 including a processor 31 and a memory 32. The processing circuit 30 may include multiple processors 31. The processing circuit 30 may include multiple memories 32.

[0068] In this embodiment, the units denoted by the reference numerals 20 to 25 represent functions possessed by the control device 9. The functions of the units denoted by the reference numerals 20 to 25 can be realized by software written as a program, firmware, or a combination of software and firmware. The program is stored in the memory 32. The control device 9 realizes the functions of the units denoted by the reference numerals 20 to 25 by executing the program stored in the memory 32 using the processor 31 (computer).

[0069] The processor 31 is also called a CPU (Central Processing Unit), etc. The memory 32 may be a semiconductor memory, etc.

[0070] Fig. 6 is a diagram showing another example of hardware resources of the control device 9. In the example shown in Fig. 6, the control device 9 includes a processing circuit 30 including a processor 31, a memory 32, and dedicated hardware 33. Fig. 6 shows an example in which some of the functions of the control device 9 are realized by the dedicated hardware 33.
