Detailed Description
The present invention will be described with reference to the accompanying drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, like reference numerals designate like or corresponding parts throughout the several views.
Fig. 1 is a diagram showing an example of an elevator apparatus according to embodiment 1. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in a hoistway 3 by means of main ropes 4.
The main rope 4 is wound around a drive sheave 6 of the hoisting machine 5. The car 1 is driven by a hoisting machine 5. The hoisting machine 5 is controlled by a control device 7. Fig. 1 shows an example of a machine room 8 in which a hoisting machine 5 and a control device 7 are provided above a hoistway 3. The hoisting machine 5 and the control device 7 may be provided in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or may be installed in a pit of the hoistway 3.
In the example shown in fig. 1, a seismic detector 9 is provided in the machine room 8. The seismic detector 9 may be provided in the hoistway 3. The seismic detector 9 is for example an accelerometer. The seismic detector 9 detects the acceleration of the building. The seismic detector 9 outputs a signal corresponding to the detected acceleration. The signal from the seismic detector 9 is input to the control device 7.
In the present embodiment, an example will be described in which the seismic detector 9 outputs three-level signals corresponding to detected accelerations. For example, when detecting a specific acceleration of 1 st level or more, the seismic detector 9 outputs a 1 st signal. The seismic detector 9 outputs a 2 nd signal when detecting acceleration of a specific 2 nd level or more. The acceleration of level 2 is greater than the acceleration of level 1. The seismic detector 9 outputs a 3 rd signal when detecting acceleration of a specific 3 rd level or more. The acceleration of level 3 is greater than the acceleration of level 2.
The car 1 includes a door 10 and a door switch 11. The door switch 11 outputs a door closing signal, for example, if the door 10 is closed. As another example, if the door 10 is opened, the door switch 11 outputs a door opening signal. A door closing signal or a door opening signal from the door switch 11 is input to the control device 7.
Fig. 2 is a diagram showing an example of functions of the control device 7. The control device 7 includes, for example, a storage unit 20, an operation control unit 21, an interruption unit 22, a door detection unit 23, and a determination unit 24.
The operation control unit 21 controls, for example, an automatic operation, a control operation, and a diagnostic operation. The automatic operation is an operation for causing the car 1 to respond to the registered calls in sequence. The control operation is an operation for evacuation of passengers in the car 1 immediately after the occurrence of an earthquake. The diagnostic operation is an operation for determining the presence or absence of an abnormality. The diagnosis operation is performed by actually moving the car 1 after the end of the control operation.
Hereinafter, the functions of the elevator apparatus will be described in detail with reference to fig. 3 to 6. Fig. 3 to 5 are flowcharts showing an example of the operation of the elevator apparatus according to embodiment 1. Fig. 3 to 5 show a series of operation flows.
While the operation control unit 21 is automatically operating, the control device 7 determines whether or not the 3 rd signal is input from the seismic detector 9 (S101). If no is determined in S101, it is determined whether or not the 2 nd signal is input from the seismic detector 9 in the control device 7 (S102). If no is determined in S102, it is determined whether or not the 1 st signal is input from the seismic sensor 9 in the control device 7 (S103).
For example, when the seismic detector 9 detects acceleration of 1 st level or more and less than 2 nd level, it outputs a 1 st signal. Thus, in S103, it is determined as yes. When the determination is yes in S103, the operation control unit 21 starts the control operation for stopping the car 1 at the nearest floor (S104).
When the control operation is started in S104, the interruption unit 22 determines whether or not a specific interruption condition is satisfied (S105). For example, the control device 7 is provided with a safety circuit. As an example, the interrupt condition is established when the safety circuit operates. If the interrupt condition is not satisfied, it is determined whether or not the car 1 has stopped at the nearest floor (S109). If the determination is no in S109, it is again determined whether or not the interrupt condition is satisfied in S105. That is, the determination of S105 by the interrupt unit 22 is continued during the time period from the time when the car 1 stops at the nearest floor in the control operation. If yes is determined in S105, the interruption unit 22 interrupts the control operation, and the car 1 is stopped in an emergency (S106).
For example, the door detecting unit 23 detects that the door 10 is opened based on a door opening signal from the door switch 11. When the door detection unit 23 detects that the door 10 is open during the control operation, the safety circuit operates. Thus, the interruption condition is satisfied, and the control operation is interrupted. Namely, the car 1 is stopped urgently. The conditions for the operation of the safety circuit are not limited to the above examples. For example, the safety circuit may be operated when a specific signal is input from another safety device to the control device 7.
When the car 1 is stopped in an emergency in S106, the interruption unit 22 determines whether or not the interruption condition is continued (S107). When the determination is yes in S107, the operation control unit 21 does not restart the control operation. The operation control unit 21 keeps stopping the car 1. On the other hand, when the determination is no in S107, the operation control unit 21 restarts the control operation (S108). For example, in S108, the operation control unit 21 moves the car 1 to the nearest floor at a specific low speed slower than the moving speed in the automatic operation. The low speed is, for example, 10m/min.
When the control operation is restarted in S108, the interruption unit 22 determines whether or not the interruption condition is satisfied (S105). When the determination is yes in S105, the above operation is performed again. On the other hand, when the car 1 is stopped at the nearest floor by performing the control operation (yes in S109), the operation control unit 21 opens the door 10. Thus, the passenger can come out of the car 1. When a predetermined time has elapsed since the door 10 was opened, the operation control unit 21 closes the door 10. When the door 10 is closed at the nearest floor, it is determined whether or not a predetermined time has elapsed since the door 10 was closed (S110). When the determination is yes in S110, the operation control unit 21 restarts the normal operation (S111).
The seismic detector 9 outputs a 2 nd signal when detecting acceleration of 2 nd level or more and less than 3 rd level. Thus, in S102, it is determined as yes. When the determination is yes in S102, the operation control unit 21 starts the control operation for stopping the car 1 at the nearest floor (S112).
When the control operation is started in S112, the interruption unit 22 determines whether or not a specific interruption condition is satisfied (S113). For example, when the safety circuit is operated, the interrupt condition is satisfied. If the interrupt condition is not satisfied, it is determined whether or not the car 1 has stopped at the nearest floor (S117). If the determination is no in S117, it is determined again whether or not the interrupt condition is satisfied in S113. That is, the determination of S113 by the interrupt unit 22 is continued during the period from the time when the car 1 stops at the nearest floor in the control operation. If yes is determined in S113, the interruption unit 22 interrupts the control operation, and the car 1 is stopped in an emergency (S114).
The interrupt condition in S113 may be the same as the interrupt condition in S105. For example, when the door detection unit 23 detects that the door 10 is open during the control operation, the safety circuit operates. Thus, the interruption condition is satisfied, and the control operation is interrupted. Namely, the car 1 is stopped urgently.
When the car 1 is stopped in an emergency in S114, the interruption unit 22 determines whether or not the interruption condition is continued to be satisfied (S115). When the determination is yes in S115, the operation control unit 21 does not restart the control operation. The operation control unit 21 keeps stopping the car 1. On the other hand, when the determination is no in S115, the operation control unit 21 restarts the control operation (S116). For example, in S116, the operation control unit 21 moves the car 1 to the nearest floor at the above-described low speed.
When the control operation is restarted in S116, the interruption unit 22 determines whether or not the interruption condition is satisfied (S113). When the determination is yes in S113, the above operation is performed again. On the other hand, when the car 1 is stopped at the nearest floor by performing the control operation (yes in S117), the operation control portion 21 opens the door 10. Thus, the passenger can come out of the car 1. When a predetermined time has elapsed since the door 10 was opened, the operation control unit 21 closes the door 10. When the door 10 is closed at the nearest floor, it is determined whether or not a predetermined time has elapsed since the door 10 was closed (S118).
When the determination is yes in S118, the operation control unit 21 starts the diagnostic operation (S119). When an abnormality is detected in the diagnostic operation (yes in S120), the operation control unit 21 stops the operation. In addition, an external report is made (S121). On the other hand, if no abnormality is detected during the diagnostic operation (no at S120), the operation control unit 21 resumes the normal operation (S122).
The seismic detector 9 outputs a 3 rd signal when detecting acceleration of 3 rd or higher. Thus, in S101, it is determined as yes. When the determination is yes in S101, the operation control unit 21 starts the control operation for stopping the car 1 at the nearest floor (S123).
When the control operation is started in S123, the interruption unit 22 determines whether or not a specific interruption condition is satisfied (S124). For example, when the safety circuit is operated, the interrupt condition is satisfied. If the interrupt condition is not satisfied, it is determined whether or not the car 1 has stopped at the nearest floor (S128). If the determination is no in S128, it is again determined whether or not the interrupt condition is satisfied in S124. That is, the determination of S124 by the interrupting unit 22 is continued during the time period from the time when the car 1 stops at the nearest floor in the control operation. If yes is determined in S124, the interruption unit 22 interrupts the control operation and brings the car 1 into emergency stop (S125).
The interrupt condition in S124 may be the same as the interrupt condition in S105 or the interrupt condition in S113. As described above, the door detecting section 23 detects the opening of the door 10. When the door detection unit 23 detects that the door 10 is open during the control operation, the safety circuit operates. Thus, the interruption condition is satisfied, and the control operation is interrupted. Namely, the car 1 is stopped urgently.
When the control operation is interrupted and the car 1 is stopped in an emergency in S125, the determination unit 24 determines whether or not a specific restart condition is satisfied (S126). The determination unit 24 determines S126 based on the time when the door detection unit 23 detects that the door 10 is open. When the determination is no in S126, the operation control unit 21 does not restart the control operation. The operation control unit 21 keeps stopping the car 1. On the other hand, when the determination is yes in S126, the operation control unit 21 restarts the control operation (S127). For example, in S127, the operation control unit 21 moves the car 1 toward the nearest floor at the low speed.
When the control operation is restarted in S127, the interruption unit 22 determines whether or not the interruption condition is satisfied (S124). When the determination is yes in S124, the above operation is performed again. On the other hand, when the car 1 is stopped at the nearest floor by performing the control operation (yes in S128), the operation control unit 21 opens the door 10. Thus, the passenger can come out of the car 1. When a predetermined time has elapsed from when the door 10 is opened, the operation control unit 21 closes the door 10. When the door 10 is closed at the nearest floor, it is determined whether or not a predetermined time has elapsed since the door 10 was closed (S129).
When the determination is yes in S129, the operation control unit 21 starts the diagnostic operation (S130). When an abnormality is detected in the diagnostic operation (yes in S131), the operation control unit 21 stops the operation. In addition, an external report is made (S132). On the other hand, if no abnormality is detected in the diagnostic operation (no in S131), the operation control unit 21 resumes the normal operation (S133).
Fig. 6 is a flowchart showing an example of the function of the determination unit 24. Fig. 6 shows an example of the operation flow performed in S126. Hereinafter, the time when the door detection unit 23 detects that the door 10 is open will also be referred to as "open time t1". When the control operation is interrupted in S125, the determination unit 24 determines whether or not the interruption condition is satisfied (S201). If the interrupt condition is not satisfied after the interrupt condition is temporarily satisfied in S124, the determination is no in S201. When the determination is no in S201, the determination unit 24 determines whether or not the interruption of the control operation in S125 is caused by the door detection unit 23 detecting that the door 10 is open (S202). When the determination is no in S202, the restart condition is not satisfied (S203).
When it is determined to be yes in S202, the determination unit 24 calculates the open time t1 from the door opening signal from the door switch 11 (S204). Next, the determination unit 24 determines whether or not the open time T1 calculated in S204 is shorter than the specific reference time T (S205). The reference time T is stored in the storage unit 20 in advance. For example, the reference time T is a specific time of 500msec or less. If the on time T1 is shorter than the reference time T, it is determined as no in S205. When the determination is no in S205, the restart condition is not satisfied (S203). That is, no is determined in S126. On the other hand, if the on time T1 is shorter than the reference time T, it is determined as yes in S205. When the determination is yes in S205, the restart condition is satisfied (S206). That is, in S126, it is determined as yes.
As described above, when the determination unit 24 determines in S126 that the restart condition is satisfied, the operation control unit 21 restarts the control operation interrupted in S125 (S127). On the other hand, if the determination unit 24 does not determine that the restart condition is satisfied in S126, the operation control unit 21 does not restart the control operation interrupted in S125.
In the example shown in the present embodiment, even when the control operation is interrupted in S125, if the restart condition is satisfied, the control operation is performed again. Therefore, in the example shown in the present embodiment, it is possible to reduce the situation in which passengers get trapped in the car 1 after an earthquake.
In the case where the 3 rd signal is output from the seismic detector 9, it is not known how much seismic activity actually occurs. Conventionally, when a safety circuit is operated after a control operation is started, the car 1 is stopped directly without restarting the control operation. However, the applicant has investigated the cause of the actual interruption of the control operation, and has found that in many cases the control operation is interrupted due to the extremely short time the door 10 is opened when the control operation is performed. The main reason for this phenomenon is that aftershock occurs when the control operation is performed.
Moreover, as known from the applicant's investigation, if the aftershock is small, the time for which the door 10 is opened is also short, and immediately after that, the door 10 is closed. Moreover, it was confirmed that: in the case where the regulating operation is interrupted by the door 10 being opened for only a very short time, there is little problem even if the regulating operation is restarted thereafter. The elevator apparatus according to the present embodiment is realized based on the investigation of the applicant. For example, the applicant has confirmed that if the reference time T is 500msec, no problem occurs at all even if the control operation is restarted within the range of investigation.
Hereinafter, other functions that can be adopted by the elevator apparatus will be described. The elevator apparatus may use a plurality of functions described below in combination.
Fig. 7 is a flowchart showing another example of the function of the determination unit 24. Fig. 7 shows an example of the operation flow performed in S126. The operation flow shown in fig. 7 corresponds to a flow in which the process shown in S207 is added to the operation flow shown in fig. 6.
When the determination is yes in S202, the determination unit 24 determines whether or not a predetermined time has elapsed since the control operation was interrupted in S125 (S207). For example, in S207, it is determined whether or not a predetermined time has elapsed since the door detection unit 23 no longer detected that the door 10 is open. When it is determined to be yes in S207, the determination section 24 calculates the open time t1 from the door signal from the door switch 11 (S204).
In the example shown in fig. 7, the restart condition is established when a predetermined time has elapsed since the control operation was interrupted in S125, and the open time T1 calculated in S204 is shorter than the reference time T. In the example shown in fig. 7, the control operation can be restarted after a predetermined time has elapsed since the occurrence of the aftershock. The determination in S207 may be performed after the determination in S205 is yes.
As another example, the control device 7 may further include a movement instruction unit 25. In this case, the elevator apparatus further includes a displacement sensor 12. The displacement sensor 12 is an example of a means for detecting the distance that the car 1 actually moves. The displacement sensor 12 is provided in the car 1, for example. A signal indicating the distance detected by the displacement sensor 12 is input to the control device 7. The above-described means may detect the distance that the car 1 actually moves based on the distance that the main rope 4 moves. As another example, the above-described mechanism may detect the distance that the car 1 actually moves from the rotation angle of the rotating body that is linked with the movement of the car 1.
Fig. 8 is a flowchart showing another example of the functions of the control device 7. Fig. 8 shows an example of the operation flow performed in S126. The operation flow shown in fig. 8 corresponds to a flow in which the processes shown in S208 and S209 are added to the operation flow shown in fig. 6.
When the determination is yes in S205, the movement command unit 25 outputs a movement command to the hoisting machine 5 (S208). The movement command output in S208 is, for example, a command for moving the car 1 a specific distance l1 in a direction in which the car 1 is away from the counterweight 2. The distance l1 is, for example, 50mm. By outputting a movement command from the movement command unit 25, the car 1 moves in a direction away from the counterweight 2. Then, the distance l2 by which the car 1 actually moves in response to the movement command from the movement command unit 25 is detected by the displacement sensor 12. The movement command output in S208 may be a command for moving the car 1 in a direction in which the car 1 approaches the counterweight 2. The movement command output in S208 may be a command for moving the car 1 in both directions of the direction in which the car 1 is away from the counterweight 2 and the direction in which the car 1 approaches the counterweight 2.
Next, the determination unit 24 determines whether or not the difference between the distance L1 and the distance L2 is shorter than the specific reference distance L (S209). The reference distance L is, for example, 0.1mm. That is, in S209, it is determined whether or not the car 1 has actually moved in accordance with the movement command from the movement command unit 25. If the difference between the distance L1 and the distance L2 is shorter than the reference distance L, it is determined as no in S209. When the determination is no in S209, the restart condition is not satisfied (S203). On the other hand, if the difference between the distance L1 and the distance L2 is shorter than the reference distance L, it is determined as yes in S209. When the determination is yes in S209, the restart condition is satisfied (S206).
In the example shown in fig. 8, if the difference between the distance L1 and the distance L2 is shorter than the reference distance L, the control operation is not restarted. Therefore, in the example shown in fig. 8, if the main rope 4 is caught by equipment in the hoistway 3 due to a residual shock, for example, the control operation can be prevented from being restarted.
In the example shown in fig. 8, the process shown in S207 may be performed before or after the process shown in S204, as in the example shown in fig. 7. For example, when it is determined to be yes in S202, the determination unit 24 determines whether or not a predetermined time has elapsed since the control operation was interrupted in S119 (S207). In this case, the movement command unit 25 outputs a movement command in S208 when a predetermined time has elapsed since the control operation was interrupted in S119 and the open time T1 calculated in S204 is shorter than the reference time T.
As another example, the control device 7 may further include a torque detection unit 26. The torque detection unit 26 detects the torque of the hoisting machine 5. When the restart condition is satisfied and the control operation is restarted in S126, the interruption unit 22 also interrupts the control operation based on the torque detected by the torque detection unit 26. For example, the interruption unit 22 interrupts the control operation when the torque detected by the torque detection unit 26 exceeds the reference torque after the control operation is restarted. The reference torque is stored in the storage unit 20 in advance. Thus, when the main rope 4 is caught by the equipment in the hoistway 3 due to the aftershock, the control operation after restarting can be immediately interrupted.
In the present embodiment, reference numerals 20 to 26 denote functions of the control device 7. Fig. 9 is a diagram showing an example of hardware resources of the control device 7. The control device 7 includes, as hardware resources, a processing circuit 30 including, for example, a processor 31 and a memory 32. The functions of the storage unit 20 are realized by the memory 32. The control device 7 executes a program stored in the memory 32 by the processor 31 to realize the functions of the respective units shown by reference numerals 21 to 26.
Fig. 10 is a diagram showing another example of the hardware resources of the control device 7. In the example shown in fig. 10, the control device 7 includes, for example, a processing circuit 30 including a processor 31, a memory 32, and dedicated hardware 33. Fig. 10 shows an example in which a part of functions of the control device 7 are realized by dedicated hardware 33. All functions of the control device 7 may be realized by dedicated hardware 33. As the dedicated hardware 33, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit: application specific integrated circuit), an FPGA (Field Programmable Gate Array: field programmable gate array), or a combination thereof can be employed.
